From 453ed90d1395a5281a8f1a0de5d8aabc66202e34 Mon Sep 17 00:00:00 2001 From: Latchesar Ionkov Date: Sun, 5 Apr 2009 16:22:16 -0500 Subject: [PATCH 0001/1012] net/9p: set correct stat size when sending Twstat messages The 9P2000 Twstat message requires the size of the stat structure to be specified. Currently the 9p code writes zero instead of the actual size. This behavior confuses some of the file servers that check if the size is correct. This patch adds a new function that calculcates the stat size and puts the value in the appropriate place in the 9P message.

The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

From now on, drivers should always use ioremap() instead of IO_ADDRESS(). In addition, remove the davinci_[read|write]* macros in favor of using ioremap.

Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean for ointing out this issue.

Also, since the enable will fail on the suspend path, the disable on the resume path will trigger unbalanced enable/disable warnings.

Practical choices at this point are GPTIMER1 or GPTIMER12. Both of these timers are in the WKUP powerdomain, and so are unaffected by chip power management. GPTIMER1 can use sys_clk as a source, for applications where a high-resolution timer is more important than power management. GPTIMER12 has the special property that it has the secure 32kHz oscillator as its source clock, which may be less prone to glitches than the off-chip 32kHz oscillator. But on HS devices, it may not be available for Linux use. It appears that most boards are fine with GPTIMER1, but BeagleBoard should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs in revisions B4 and below. Modify board-omap3beagle.c to use GPTIMER12. This patch originally used a Kbuild config option to select the GPTIMER, but was changed to allow this to be specified in board-*.c files, per Tony's request. Kalle Vallo found a bug in an earlier version of this patch - thanks Kalle. Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and 3430SDP.

So, what's happening here is that the drive is reporting a sense of 2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and then we ask for the media event notification before checking that result at all. The check_media_event_descriptor() call isn't getting a check condition, but it's also reporting that the tray is closed and that there's no media. In actuality it doesn't yet know if there's media or not, but there's no way to express that in the media event status field.

The only reference to them is through any outstanding exchanges pending on the rogue ports. If the module is removed while a retry is set on a rogue port (say a Plogi retry for instance), this retry is not cancelled because there is no reference to the rogue port in the discovery rports list. Thus the local port can clean itself up, delete the exchange pool, and then the rogue port timeout can fire and try to start up another exchange. This patch tracks the rogue ports in a new list disc->rogue_rports. Creating a new list instead of using the disc->rports list keeps remote port code change to a minimum. 1) Whenever a rogue port is created, it is immediately added to the disc->rogue_rports list. 2) When the rogues port goes to ready, it is removed from the rogue list and the real remote port is added to the disc->rports list 3) The removal of the rogue from the disc->rogue_rports list is done in the context of the fc_rport_work() workQ thread in discovery callback. 4) Real rports are removed from the disc->rports list like before. Lookup is done only in the real rports list. This avoids making large changes to the remote port code. 5) In fc_disc_stop_rports, the rogues list is traversed in addition to the real list to stop the rogue ports and issue logoffs on them. This way, rogue ports get cleaned up when the local port goes away. 6) rogue remote ports are not removed from the list right away, but removed late in fc_rport_work() context, multiple threads can find the same remote port in the list and call rport_logoff(). Rport_logoff() only continues with the logoff if port is not in NONE state, thus preventing multiple logoffs and multiple list deletions. 7) Since the rport is removed from the disc list at a later stage (in the disc callback), incoming frames can find the rport even if rport_logoff() has been called on the rport. When rport_logoff() is called, the rport state is set to NONE, and we are trying to cancel all exchanges and retries on that port. While in this state, if an incoming Plogi/Prli/Logo or other frames match the rport, we should not reply because the rport is in the NONE state. Just drop the frame, since the rport will be deleted soon in the disc callback (fc_rport_work) 8) In fc_disc_single(), remove rport lookup and call to fc_disc_del_target. fc_disc_single() is called from recv_rscn_req() where rport lookup and rport_logoff is already done.

In OSD2r01-r04 it was aligned on 2 bytes. (This is because in OSD2r01 the complete element was 8 bytes padded at end but the header was not adjusted and caused permanent miss-alignment.) OSD1 elements are not padded and might be or might not be aligned. OSD1 is still supported. In this code we do all the code re-factoring to separate OSD1/OSD2 differences but do not change actual wire format. All wire format changes will happen in one patch later, for bisect-ability.

So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed.

The compatibilities are a bit different based on which kernel was used previously + Users of TI/MV kernels no longer see mtd2 "params" (mainline u-boot env is in a different place) * Filesystem is now mtd2 ... vs mtd3 + Users of GIT kernels now see mtd0 and mtd1 partitions * Filesystem partition starts 640 KBytes earlier * Filesystem is now mtd2 ... vs mtd0 * Linux now *uses* the flash-resident BBT * Removes annoying slowdown/hiccup during boot * Potentially ~64KB less space available with TI/MV kernels If you *used* NAND partitions from Linux, there is no solution that's fully compatible with all previous kernels in those respects ... ergo this "best compromise". It'd be good to back back up the filesystem data; or, carry your own backwards-compatibility patch for awhile.

This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen.

This patch fixes this by checking the OOM bit in the NAPI poll handler before attempting to do rx refill. This means that once OOM occurs, we won't try to do any memory allocations again until the next invocation of the poll handler. While we're at it, change the OOM flag to be a single bit instead of one bit per receive queue since OOM is a system state rather than a per-queue state, and cancel the OOM timer on entry to the NAPI poll handler if it's running to prevent it from firing when we've already come out of OOM.

This can under heavy traffic occasionally lead to small numbers being added to the upper half of the 64bit mib counter even though no 32bit wrap has occured. Since we poll the mib counters at least every 30 seconds anyway, we might as well just skip the reads of the upper halves of the hardware counters without breaking the stats, which this patch does.

This has been reported via bugzilla a while ago (#717) and has recently also shown up via lockdep. So allocate a temporary buffer to format the kernel getbmap structures into and then copy them out after dropping the locks. A little problem with this is that we limit the number of extents we can copy out by the maximum allocation size, but I see no real way around that.

This was useful to avoid regressions, but is long overdue to be removed. Now that the Kerberos (asn/spnego) code is working in fs/cifs/sess.c, and the NTLMSSP code moved (NTLMSSP blob setup be rewritten with the next patch in this series) quite a bit of dead code from fs/cifs/connect.c now can be removed. This old code should have been removed last year, but the earlier krb5 patches did not move/remove the NTLMSSP code which we had asked to be done first. Since no one else volunteered, I am doing it now. It is extremely important that we continue to examine the documentation for this area, to make sure our code continues to be uptodate with changes since Windows 2003.

This document +describes the multi-touch (MT) protocol which allows kernel drivers to +report details for an arbitrary number of fingers. + + +Usage +----- + +Anonymous finger details are sent sequentially as separate packets of ABS +events. Only the ABS_MT events are recognized as part of a finger +packet. The end of a packet is marked by calling the input_mt_sync() +function, which generates a SYN_MT_REPORT event. The end of multi-touch +transfer is marked by calling the usual input_sync() function. + +A set of ABS_MT events with the desired properties is defined. The events +are divided into categories, to allow for partial implementation. The +minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and +ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the +device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size +of the approaching finger. Anisotropy and direction may be specified with +ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with +more granular information may specify general shapes as blobs, i.e., as a +sequence of rectangular shapes grouped together by an +ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify +whether the touching tool is a finger or a pen or something else. + + +Event Semantics +--------------- + +The word "contact" is used to describe a tool which is in direct contact +with the surface. A finger, a pen or a rubber all classify as contacts. + +ABS_MT_TOUCH_MAJOR + +The length of the major axis of the contact. The length should be given in +surface units. If the surface has an X times Y resolution, the largest +possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal. + +ABS_MT_TOUCH_MINOR + +The length, in surface units, of the minor axis of the contact. If the +contact is circular, this event can be omitted. + +ABS_MT_WIDTH_MAJOR + +The length, in surface units, of the major axis of the approaching +tool. This should be understood as the size of the tool itself. The +orientation of the contact and the approaching tool are assumed to be the +same. + +ABS_MT_WIDTH_MINOR + +The length, in surface units, of the minor axis of the approaching +tool. Omit if circular. + +The above four values can be used to derive additional information about +the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates +the notion of pressure. The fingers of the hand and the palm all have +different characteristic widths [1]. + +ABS_MT_ORIENTATION + +The orientation of the ellipse. The value should describe half a revolution +clockwise around the touch center. The scale of the value is arbitrary, but +zero should be returned for an ellipse aligned along the Y axis of the +surface. As an example, an index finger placed straight onto the axis could +return zero orientation, something negative when twisted to the left, and +something positive when twisted to the right. This value can be omitted if +the touching object is circular, or if the information is not available in +the kernel driver. + +ABS_MT_POSITION_X + +The surface X coordinate of the center of the touching ellipse. + +ABS_MT_POSITION_Y + +The surface Y coordinate of the center of the touching ellipse. + +ABS_MT_TOOL_TYPE + +The type of approaching tool. A lot of kernel drivers cannot distinguish +between different tool types, such as a finger or a pen. In such cases, the +event should be omitted. The protocol currently supports MT_TOOL_FINGER and +MT_TOOL_PEN [2]. + +ABS_MT_BLOB_ID + +The BLOB_ID groups several packets together into one arbitrarily shaped +contact. This is a low-level anonymous grouping, and should not be confused +with the high-level contactID, explained below. Most kernel drivers will +not have this capability, and can safely omit the event. + + +Finger Tracking +--------------- + +The kernel driver should generate an arbitrary enumeration of the set of +anonymous contacts currently on the surface. The order in which the packets +appear in the event stream is not important. + +The process of finger tracking, i.e., to assign a unique contactID to each +initiated contact on the surface, is left to user space; preferably the +multi-touch X driver [3]. In that driver, the contactID stays the same and +unique until the contact vanishes (when the finger leaves the surface). The +problem of assigning a set of anonymous fingers to a set of identified +fingers is a euclidian bipartite matching problem at each event update, and +relies on a sufficiently rapid update rate. + +Notes +----- + +In order to stay compatible with existing applications, the data +reported in a finger packet must not be recognized as single-touch +events. In addition, all finger data must bypass input filtering, +since subsequent events of the same type refer to different fingers. + +The first kernel driver to utilize the MT protocol is the bcm5974 driver, +where examples can be found. + +[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the +difference between the contact position and the approaching tool position +could be used to derive tilt. +[2] The list can of course be extended. +[3] The multi-touch X driver is currently in the prototyping stage. At the +time of writing (April 2009), the MT protocol is not yet merged, and the +prototype implements finger matching, basic mouse support and two-finger +scrolling. The project aims at improving the quality of current multi-touch +functionality available in the synaptics X driver, and in addition +implement more advanced gestures. -- GitLab From d185cda7712fd1d9e349174639d76eadc66679be Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 30 Apr 2009 17:45:10 +0000 Subject: [PATCH 0194/1012] [CIFS] rename cifs_strndup to cifs_strndup_from_ucs In most cases, cifs_strndup is converting from Unicode (UCS2 / UTF-32) to the configured local code page for the Linux mount (usually UTF8), so Jeff suggested that to make it more clear that cifs_strndup is doing a conversion not just memory allocation and copy, rename the function to including "from_ucs" (ie Unicode) Signed-off-by: Steve French --- fs/cifs/CHANGES | 6 +++++- fs/cifs/cifs_unicode.c | 6 +++--- fs/cifs/cifs_unicode.h | 7 ++++--- fs/cifs/cifssmb.c | 12 ++++++------ fs/cifs/connect.c | 5 +++-- fs/cifs/sess.c | 8 ++++---- 6 files changed, 25 insertions(+), 19 deletions(-) diff --git a/fs/cifs/CHANGES b/fs/cifs/CHANGES index 1bf81813627..1b0643c2eac 100644 --- a/fs/cifs/CHANGES +++ b/fs/cifs/CHANGES @@ -2,7 +2,11 @@ Version 1.58 ------------ Guard against buffer overruns in various UCS-2 to UTF-8 string conversions when the UTF-8 string is composed of unusually long (more than 4 byte) converted -characters. +characters.

The ocfs2 directory index updates two blocks when we remove an entry - the dx root and the dx leaf. OCFS2_DELETE_INODE_CREDITS was only accounting for the dx leaf. This shows up when ocfs2_delete_inode() runs out of credits in jbd2_journal_dirty_metadata() at "J_ASSERT_JH(jh, handle->h_buffer_credits > 0);". The test that caught this was running dirop_file_racer from the ocfs2-test suite with a 250-character filename PREFIX. Run on a 512B blocksize, it forces the orphan dir index to grow large enough to trigger.

That's not always the case. Instead of passing "max_len" to the string converter, pass "min(len, max_len)", which makes it do the right thing while still keeping the parser confined to the response. Also fix up the prototypes of this function and the callers so that max_len is unsigned (like len is).

The notion of compatibility events just started with POWER6. So there is no way that any other tool could exist that is using these oprofile_cpu_type strings we want to change.

This is resulting in modpost's main function calling read_markers() and then write_markers() on the same file. We then have read_markers() mmap'ing the file, and writer_markers() opening that same file for writing. The issue is that read_markers() exits without munmap'ing the file and is as a matter holding a reference on Modules.markers. When write_markers() is opening that very same file for writing, we still have a reference on it and cygwin (Windows?) is then making fopen() fail with EPERM. Calling release_file() before exiting read_markers() clears that reference (and memory leak) and fopen() then succeeds. Tested on both cygwin (1.3.22) and Linux. Also ran modpost within valgrind on Linux to make sure that the munmap'ed file was not accessed after read_markers() Signed-off-by: Cedric Hombourger Cc: Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg --- scripts/mod/modpost.c | 1 + 1 file changed, 1 insertion(+) diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index 8d46ea7d671..57d71a5f31b 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -1990,6 +1990,7 @@ static void read_markers(const char *fname) if (!mod->skip) add_marker(mod, marker, fmt); } + release_file(file, size); return; fail: fatal("parse error in markers list file\n"); -- GitLab From a182ad3d0f858f50bb719a48bb35a013e12366c5 Mon Sep 17 00:00:00 2001 From: Nico Schottelius Date: Sat, 25 Apr 2009 09:48:39 +0200 Subject: [PATCH 0217/1012] kbuild: fix scripts/setlocalversion with git When using trees like wireless-testing, which have untagged tags, scripts/setlocalversion does not display any git indication for localversion.

But this heuristic has two problems: it will miss a bad section that has no relocations, and it will incorrectly flag many gcc-generated sections as bad when compiling with -ffunction-sections -fdata-sections. On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one: WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.

The commit added a warning when handle_IRQ_event() is called outside of hard interrupt context. This breaks the generic tasklet based interrupt resend mechanism which is used when the hardware has no way to retrigger the interrupt. So we get a warning for a use case which is correct and worked for years. Remove it.

Avoid an endless loop issue by requiring that a highres valid clocksource be installed before we call tick_periodic() in a loop when using ONESHOT mode. The result is we will only increment jiffies once per interrupt until a continuous hardware clocksource is available. Without this, we can run into a endless loop, where each cycle through the loop, jiffies is updated which increments time by tick_period or more (due to clock steering), which can cause the event programming to think the next event was before the newly incremented time and fail causing tick_periodic() to be called again and the whole process loops forever.

This allows the filesystem to have full control of page dirtying events coming from the VM. Rather than simply hold the page locked over the page_mkwrite call, we call page_mkwrite with the page unlocked and allow callers to return with it locked, so filesystems can avoid LOR conditions with page lock. The problem with the current scheme is this: a filesystem that wants to associate some metadata with a page as long as the page is dirty, will perform this manipulation in its ->page_mkwrite. It currently then must return with the page unlocked and may not hold any other locks (according to existing page_mkwrite convention). In this window, the VM could write out the page, clearing page-dirty. The filesystem has no good way to detect that a dirty pte is about to be attached, so it will happily write out the page, at which point, the filesystem may manipulate the metadata to reflect that the page is no longer dirty. It is not always possible to perform the required metadata manipulation in ->set_page_dirty, because that function cannot block or fail. The filesystem may need to allocate some data structure, for example. And the VM cannot mark the pte dirty before page_mkwrite, because page_mkwrite is allowed to fail, so we must not allow any window where the page could be written to if page_mkwrite does fail. This solution of holding the page locked over the 3 critical operations (page_mkwrite, setting the pte dirty, and finally setting the page dirty) closes out races nicely, preventing page cleaning for writeout being initiated in that window. This provides the filesystem with a strong synchronisation against the VM here. - Sage needs this race closed for ceph filesystem. - Trond for NFS (http://bugzilla.kernel.org/show_bug.cgi?id=12913). - I need it for fsblock. - I suspect other filesystems may need it too (eg. btrfs). - I have converted buffer.c to the new locking. Even simple block allocation under dirty pages might be susceptible to i_size changing under partial page at the end of file (we also have a buffer.c-side problem here, but it cannot be fixed properly without this patch). - Other filesystems (eg. NFS, maybe btrfs) will need to change their page_mkwrite functions themselves. [ This also moves page_mkwrite another step closer to fault, which should eventually allow page_mkwrite to be moved into ->fault, and thus avoiding a filesystem calldown and page lock/unlock cycle in __do_fault. ] [akpm@linux-foundation.org: fix derefs of NULL ->mapping] Cc: Sage Weil Cc: Trond Myklebust Signed-off-by: Nick Piggin Cc: Valdis Kletnieks Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- Documentation/filesystems/Locking | 24 ++++--- fs/buffer.c | 10 +-- mm/memory.c | 108 +++++++++++++++++++++--------- 3 files changed, 98 insertions(+), 44 deletions(-) diff --git a/Documentation/filesystems/Locking b/Documentation/filesystems/Locking index 76efe5b71d7..3120f8dd2c3 100644 --- a/Documentation/filesystems/Locking +++ b/Documentation/filesystems/Locking @@ -512,16 +512,24 @@ locking rules: BKL mmap_sem PageLocked(page) open: no yes close: no yes -fault: no yes -page_mkwrite: no yes no +fault: no yes can return with page locked +page_mkwrite: no yes can return with page locked access: no yes - ->page_mkwrite() is called when a previously read-only page is -about to become writeable.

Considering hierarchy, shrinking has to be done from the mem_over_limit, not from the memcg which the page would be charged to. mem_cgroup_try_charge_swapin() does all of these things properly, so we use it and call cancel_charge_swapin when it succeeded.

Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears. This happens on every switch between text consoles.

That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

But NR_CPUS proportional isn't good calculation. In general, possibility of lock contention is proportional to the number of online cpus, not theorical maximum cpus (NR_CPUS). The current kernel has generic percpu-counter stuff. using it is right way. it makes code simplify and percpu_counter_read_positive() don't make underflow issue.

On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.

This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info().

The whole approach is actually fully broken and based on assumptions that are no longer valid. With the introduction of Simple Pairing support, the creation of low-level ACL links got changed. This change invalidates the reason why in the past two independent work queues have been used for adding/removing sysfs devices. The adding of the actual sysfs device is now postponed until the host controller successfully assigns an unique handle to that link. So the real synchronization happens inside the controller and not the host. The only left-over problem is that some internals of the sysfs device handling are not initialized ahead of time. This leaves potential access to invalid data and can cause various NULL pointer dereferences. To fix this a new function makes sure that all sysfs details are initialized when an connection attempt is made. The actual sysfs device is only registered when the connection has been successfully established. To avoid a race condition with the registration, the check if a device is registered has been moved into the removal work. As an extra protection two flush_work() calls are left in place to make sure a previous add/del work has been completed first.

This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

Thus, the i2c bus connected to the controller gets stuck afterwards. I have seen this kind of error on a custom board in certain load situations most probably caused by interference or noise. A possible reaction is to let the controller generate a STOP condition. This is documented in the PCA9564 data sheet (2006-09-01) and the same is done for other NACK states as well. Further, state 0x38 isn't handled completely, either. Try to do another START in this case like the data sheet says. As this couldn't be tested, I've added a comment to try to reset the chip if the START doesn't help as suggested by Wolfram Sang.

To see that, run the following command on a fbdev console with a 24bpp video mode, using a non-accelerated driver such as (u)vesafb: reset ; echo -e '\e[41mtest\e[K' The expected result is 'test' displayed on a line with red background. Instead of that, 'test' has a red background, but the rest of the line (rendered using fillrect()) contains a distored colorful pattern. This patch fixes the problem by correctly computing rotation shifts. It has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

The problem is that under NOMMU conditions it is really important to be able to allocate large contiguous chunks of memory, but when munmap() or exit_mmap() releases big stretches of memory, return of these to the buddy allocator can be deferred, and when it does finally happen, it can be in small chunks. Whilst the fragmentation this incurs isn't so much of a problem under MMU conditions as userspace VM is glued together from individual pages with the aid of the MMU, it is a real problem if there isn't an MMU. By clamping the page freeing queue size to 0, pages are returned to the allocator immediately, and the buddy detector is more likely to be able to glue them together into large chunks immediately, and fragmentation is less likely to occur. By disabling batching of frees, and by turning off the trimming of excess space during boot, Coldfire can manage to boot.

Make the initial setting of this variable a Kconfig configuration option. The reason there can be excess space is that the allocator only allocates in power-of-2 size chunks, but mmap()'s can be made in sizes that aren't a power of 2. There are two alternatives: (1) Keep the excess as dead space. The dead space then remains unused for the lifetime of the mapping. Mappings of shared objects such as libc, ld.so or busybox's text segment may retain their dead space forever. (2) Return the excess to the allocator. This means that the dead space is limited to less than a page per mapping, but it means that for a transient process, there's more chance of fragmentation as the excess space may be reused fairly quickly. During the boot process, a lot of transient processes are created, and this can cause a lot of fragmentation as the pagecache and various slabs grow greatly during this time. By turning off the trimming of excess space during boot and disabling batching of frees, Coldfire can manage to boot. A better way of doing things might be to have /sbin/init turn this option off. By that point libc, ld.so and init - which are all long-duration processes - have all been loaded and trimmed.

When md is loading a bitmap which it knows is out of date, it fills each page with 1s and writes it back out again. However the write_page call makes used of bitmap->file_pages and bitmap->last_page_size which haven't been set correctly yet. So this can sometimes fail. Move the setting of file_pages and last_page_size to before the call to write_page. This bug can cause the assembly on an array to fail, thus making the data inaccessible.

If we have a raid10 with multiple missing devices, and we recover just one of these to a spare, then we risk (depending on the bitmap and array chunk size) clearing bits of the bitmap for which recovery isn't complete (because a device is still missing). This can lead to a subsequent "re-add" being recovered without any IO happening, which would result in loss of data. This patch takes the safe approach of not clearing bitmap bits if the array will still be degraded. This patch is suitable for all active -stable kernels.

Being able to write 'clean' to an 'array_state' of an inactive array to activate it in 'clean' mode is both unnecessary and inconvenient. It is unnecessary because the same can be achieved by writing 'active'. This activates and array, but it still remains 'clean' until the first write. It is inconvenient because writing 'clean' is more often used to cause an 'active' array to revert to 'clean' mode (thus blocking any writes until a 'write-pending' is promoted to 'active'). Allowing 'clean' to both activate an array and mark an active array as clean can lead to races: One program writes 'clean' to mark the active array as clean at the same time as another program writes 'inactive' to deactivate (stop) and active array. Depending on which writes first, the array could be deactivated and immediately reactivated which isn't what was desired. So just disable the use of 'clean' to activate an array. This avoids a race that can be triggered with mdadm-3.0 and external metadata, so it suitable for -stable.

The MOVW and MOVT are both load-immediate instructions, MOVW loads 16 bits into the bottom half of a register, and MOVT loads 16 bits into the top half of a register. The relocation information for these instructions has a full 32 bit value, plus an addend which is stored in the 16 immediate bits in the instruction itself. The immediate bits in the instruction are not contiguous (the register # splits it into a 4 bit and 12 bit value), so the addend has to be extracted accordingly and added to the value. The value is then split and put into the instruction; a MOVW uses the bottom 16 bits of the value, and a MOVT uses the top 16 bits.

And to make sure somebody can't just start from the same original seed of all-zeroes, and then do the "half_md4_transform()" over and over until they get the same sequence as the kernel has, each iteration also mixes in the same old "current->pid + jiffies" we used - so we should now have a regular strong pseudo-number generator, but we also have one that doesn't have a single seed. Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It has no real meaning. It could be anything. I just picked the previous seed, it's just that now we keep the state in between calls and that will feed into the next result, and that should make all the difference. I made that hash be a per-cpu data just to avoid cache-line ping-pong: having multiple CPU's write to the same data would be fine for randomness, and add yet another layer of chaos to it, but since get_random_int() is supposed to be a fast interface I did it that way instead. I considered using "__raw_get_cpu_var()" to avoid any preemption overhead while still getting the hash be _mostly_ ping-pong free, but in the end good taste won out.

This caused problems later when the consumer attempted to unmap the pages using the page-list (using the list addresses which were assumed to be still in CPU-endian order). Fix the mlx4 driver to allocate two buffers and use a private buffer for the hardware-format bus addresses. This patch fixes , an NFS/RDMA server crash. The cause of the crash was found by Vu Pham of Mellanox. The fix is along the lines suggested by Steve Wise in comment #21 in bug 1571.

The problem arises because fwmarks are stored in the 4th octet of a union nf_inet_addr .all, however in the case of IPv4 only the first octet, corresponding to .ip, is assigned and compared. In other words, using .all = { 0, 0, 0, htonl(svc->fwmark) always results in a value of 0 (32bits) being stored for IPv4. This means that one fwmark can be used, as it ends up being mapped to 0, but things break down when multiple fwmarks are used, as they all end up being mapped to 0. As fwmarks are 32bits a reasonable fix seems to be to just store the fwmark in .ip, and comparing and storing .ip when fwmarks are used. This patch makes the assumption that in calls to ip_vs_ct_in_get() and ip_vs_sched_persist() if the proto parameter is IPPROTO_IP then we are dealing with an fwmark. I believe this is valid as ip_vs_in() does fairly strict filtering on the protocol and IPPROTO_IP should not be used in these calls unless explicitly passed when making these calls for fwmarks in ip_vs_sched_persist().

Now all platform_driver is registered by platform_driver_register, which makes probe()/release()/... of platform_driver passed parameter of platform_device *, so platform driver can get platform_data from platform_device; 2. Other kind of devices do not need to use platform_data, we can decrease size of device if moving it to platform_device. Taking into consideration of thousands of files to be fixed and they can't be finished in one night(maybe it will take a long time), so we keep platform_data in device to allow two kind of cases coexist until all platform devices pass its platfrom data from platform_device->platform_data. All patches to do this kind of conversion are welcome. As we don't really want to do it, it was a bad idea.

It wouldn't cause corruption, but could cause decreased performance due to allocating a larger chunk of the journal (~ 27 blocks) than it would actually use. This patch loads the xattr root dentry at xattr initialization and creates it on-demand. Since we're using the cached dentry, there's no point in keeping lookup_or_create_dir around, so that's removed.

It did this by checking that the driver defined a method for the try_fmt handler for that buffer type. However, try_fmt is optional and a driver might not provide it even though it does support that type. So use g_fmt instead, since that isn't optional. This should fix a problem with VBI capture with saa7146.

In case the connection setup fails, hci_dev_put() is never called. Procedure to reproduce the issue: # hciconfig hci0 up # lsmod | grep btusb -> "used by" refcount = 1 # hcitool cc -> will get timeout # lsmod | grep btusb -> "used by" refcount = 2 # hciconfig hci0 down # lsmod | grep btusb -> "used by" refcount = 1 # rmmod btusb -> ERROR: Module btusb is in use The hci_dev_put() call got moved into del_conn() with the 2.6.25 kernel to fix an issue with hci_dev going away before hci_conn. However that change was wrong and introduced this problem. When calling hci_conn_del() it has to call hci_dev_put() after freeing the connection details. This handling should be fully symmetric. The execution of del_conn() is done in a work queue and needs it own calls to hci_dev_hold() and hci_dev_put() to ensure that the hci_dev stays until the connection cleanup has been finished.

If that happens then, the connection attempt will be canceled. This only applies to outgoing connections, but currently it can also be triggered by incoming connection. Don't call hci_acl_connect_cancel() on incoming connection since these have to be either accepted or rejected in this state. Once they are successfully connected they need to be fully disconnected anyway. Also remove the wrong hci_acl_disconn() call for SCO and eSCO links since at this stage they can't be disconnected either, because the connection handle is still unknown.

So it's not sufficient to ensure that you use phys_addr_t or uint64_t everywhere you handle physical addresses -- you also have to avoid using the construct 'addr & PAGE_MASK', because that will strip the high 32 bits of the address. This patch avoids that problem by using PHYSICAL_PAGE_MASK instead of PAGE_MASK where appropriate. It leaves '& PAGE_MASK' in a few instances that don't matter -- where it's being used on the virtual bus addresses we're dishing out, which are 32-bit anyway. Since PHYSICAL_PAGE_MASK is not present on other architectures, we have to define it (to PAGE_MASK) if it's not already defined. Maybe it would be better just to fix PAGE_MASK for i386/PAE?

This usually works well but if an error occurs during configuration stage, ata_dev_revalidate_and_attach() returns with error code and forgets new_mask. On the retry run, dev->class is set and new_mask for the device is clear, so the device just gets revalidated and thus ends up skipping post-configuration procedure including scheduling of SCSI_HOTPLUG for the device. When this occurs, ATA part of probing works fine but SCSI probing usually doesn't happen and makes the device unreachable. The behavior has been around for a very long time but it has been uncovered with the recent addition of 1_5_GBPS horkage which uses -EAGAIN return value from ata_dev_configure() to restart the probing sequence after forcing cable speed. This can be fixed by making sure dev->class is permanently set only after all configurations are successfully complete. Fix it.

For any *.text section, literals are placed in a corresponding *.literal section. The linker script (vmlinux.lds) must place these in the correct order. It must also combine them, when the *.text section can be larger than L32R's 256 kB range. For example, this doesn't work: *(.literal) *(.text) because L32R instructions at the end of .text can't reach the literals. The linker can solve this if they are combined in parentheses, like this: *(.literal .text) because it is now allowed mix literals in .text to bring them in range. None of this is done by standard vmlinux.lds.h macros such as TEXT_TEXT and INIT_TEXT. To avoid replicating the logic of that header file, we instead post-process the generated linker script to convert *(xxx.text) to *(xxx.literal xxx.text) for the following text sections: .text .ref.text .*init.text .*exit.text .text.* using a sed script. To do this we must override the default rule for vmlinux.lds (see scripts/Makefile.build and the top-level Makefile) to insert this extra step.

It checks bio->bi_idx against bio->bi_vcnt, but the subsequent code uses idx (which is, bio->bi_idx + next_idx) as the array index into bio_vec array. This means that the test really make sense only at the first iteration of !(nr_bytes >=bio->bi_size) case (when next_idx == zero). Fix this by replacing bio->bi_idx with idx.

This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination). If respective flag is not set, the driver assumes dma-unmapping as page.

This would not be a problem except that hugetlbfs also provide a ->readpage implementation. As it exists, the core VM can assume the base page size is being used, allocate pages on behalf of the filesystem, insert them into the page cache and call ->readpage to populate them. These pages are the wrong size and at the wrong offset for hugetlbfs causing confusion. This patch deletes the ->readpage implementation for hugetlbfs on the grounds the core VM should not be allocating and populating pages on behalf of hugetlbfs. There should be no existing users of the ->readpage implementation so it should not cause a regression.

This problem doesn't occur during normal operation. You have to 1) Boot with wireless enabled. eeepc-laptop should load automatically. 2) modprobe -r eeepc-laptop 3) modprobe eeepc-laptop On boot, the default rfkill state will be set to enabled. With the current core code, step 2) will disable the wireless. Therefore in step 3), the wireless will change state during registration, from disabled to enabled.

This is easily detected. The RFKILL API states that in such cases, we should call rfkill_force_state() to notify the core. I have reported the bug to Asus. I believe this is the right thing to do for robustness, even if this particular firmware bug is fixed. 2) The same bug causes the wireless toggle key to be reported as 0x11 instead of 0x10. 0x11 is otherwise unused, so it should be safe to add this as a new keycode. The bug is triggered by removing the laptop battery while hibernated. On resume, the wireless toggle key causes the firmware to toggle the wireless state itself. (Also, the key is reported as 0x11 when the current wireless state is OFF). This is very poor behaviour because the OS can't predict whether the firmware is controlling the RFKILL state. Without this workaround, the bug means users have to press the wireless toggle key twice to enable, due to the OS/firmware conflict. (Assuming rfkill-input or equivalent is being used). The workaround avoids this. I believe that acpid scripts which toggle the value of the sysfs state file when the toggle key is pressed will be rendered ineffective by the bug, regardless of this workaround. If they simply toggle the state, when the firmware has already toggled it, then you will never see a state change. Tested on "EEEPC 4G" only.

SHE underclocks and undervolts the FSB and undervolts the CPU (at preset 2, "powersave"), or slightly overclocks the CPU (at preset 0, "performance"). Preset 1 is the default setting with default clocks and voltage. The new eeepc-laptop driver doesn't support it anymore. The attached patch adds support for it to eeepc-laptop. It's very straight-forward and almost trivial.

When ext4_get_blocks_wrap() is called with create=1, the uninitialized extent is converted into an initialized one, so the BH_Unwritten flag is no longer appropriate.

In #20896 we found that vbetool clobbers the IER. In KMS mode this is particularly bad since we don't set the interrupt regs late (in EnterVT), so we'd fail to get *any* interrupts at all after X started (since some distros have scripts that call vbetool at X startup apparently). So this patch checks IER at wait_request time, and re-enables interrupts if it's been clobbered. In a proper config this check should never be triggered. This is really a distro issue, but having a sanity check is nice, as long as it doesn't have a real performance hit.

With kernel mode-setting, this becomes a problem, and makes native resolution boot go haywire -- for example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080 display uses only the top left 1024x768, and auto-configured X will end up only 1024x768 as well. With this change, graphical boot and X both do 1920x1080 as expected. Note that we're simply embracing and extending the early bail-out code in place for the Mac Mini here. The xorg intel driver uses pci subsystem device and vendor id for matching, while we're using dmi lookups here. The MSI addition is courtesy of and tested by Bill Nottingham.

One of the "operations" that the device indicates is "queue a packet and update the window start". When the queue is empty, this is equivalent to "deliver the packet and update the window start". That case was optimized in i2400m_roq_queue_update_ws() so that we would not pointlessly queue and dequeue a packet. However, when the optimization was active, it wasn't updating the window start. That caused the reorder management code to get confused later on with what seemed to be wrong reorder requests from the device. Thus the fix implemented is to do the right thing and update the window start in both cases, when the queue is empty (and the optimization is done) and when not.

Background ---------- The performance monitor unit of the 64-bit POWER processor family has the ability to collect accurate instruction-level samples when profiling on marked events (i.e., "PM_MRK_"). In processors prior to POWER6, the MMCRA register contained "slot information" that the oprofile kernel driver used to adjust the value latched in the SIAR at the time of a PMU interrupt. But as of POWER6, these slot bits in MMCRA are no longer necessary for oprofile to use, since the SIAR itself holds the accurate sampled instruction address. With POWER6, these MMCRA slot bits were zero'ed out by hardware so oprofile's use of these slot bits was, in effect, a NOP. But with POWER7, these bits are no longer zero'ed out; however, they serve some other purpose rather than slot information. Thus, using these bits on POWER7 to adjust the SIAR value results in samples being attributed to the wrong instructions. The attached patch changes the oprofile kernel driver to ignore these slot bits on all newer processors starting with POWER6.

However, for a number of mpic implementations we have no isu (thus pass in 0) and will end up with a no linear map (size = 0). This causes us to always call irq_find_mapping() from mpic_get_irq(). By moving the allocation of the host map to after we've determined the number of sources we can actually benefit from having a linear map for the non-isu users that covers all the interrupt sources.

First, historically, we don't allocate the ROM resource in the resource tree. I'm not entirely certain of why, I susepct they often contained garbage on x86 but it's hard to tell. This causes the current generic code to always call pci_assign_resource() when trying to access the said ROM from sysfs, which will try to re-assign some new address regardless of what the ROM BAR was already set to at boot time. This can be a problem on hypervisor platforms like pSeries where we aren't supposed to move PCI devices around (and in fact probably can't). Second, our code that generates the PCI tree from the OF device-tree (instead of doing config space probing) which we mostly use on pseries at the moment, didn't set the (new) flag IORESOURCE_SIZEALIGN on any resource. That means that any attempt at re-assigning such a resource with pci_assign_resource() would fail due to resource_alignment() returning 0. This fixes this by doing these two things: - The code that calculates resource flags based on the OF device-node is improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at it also set IORESOURCE_READONLY for ROMs since we were lacking that too - We now allocate ROM resources as part of the resource tree. However to limit the chances of nasty conflicts due to busted firmwares, we only do it on the second pass of our two-passes allocation scheme, so that all valid and enabled BARs get precedence. This brings pSeries back the ability to access PCI ROMs via sysfs (and thus initialize various video cards from X etc...).

Work is progressing to switch away from pdflush as the process backing for flushing out dirty data. So it seems pointless to add more knobs to control pdflush threads. The original author of the patch did not have any specific use cases for adding the knobs, so we can easily revert this before 2.6.30 to avoid having to maintain this API forever.

The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

This could potentially cause the wrong location on disk to be read or written to, including potentially causing the corruption of the block group descriptors and/or inode table. This bug has been in the ext4 code since almost the very beginning of ext4's development. Fortunately once the data is stored in the page cache cache, ext4_get_blocks() doesn't need to be called, so trying to replicate this problem to the point where we could identify its root cause was *extremely* difficult. Many thanks to Kevin Shanahan for working over several months to be able to reproduce this easily so we could finally nail down the cause of the corruption.

The same can happen for iscsi when transitioning from logged in to failed and blocking the sdevs. This patch converts iscsi and fc's transitions back to use DID_IMM_RETRY instead of DID_TRANSPORT_DISRUPTED which has a limited number of retries that we do not want to use for handling this race.

It appears that the hit is entirely due to the paravirtualized spinlocks introduced by: | commit 8efcbab674de2bee45a2e4cdf97de16b8e609ac8 | Date: Mon Jul 7 12:07:51 2008 -0700 | | paravirt: introduce a "lock-byte" spinlock implementation The extra call/return in the spinlock path is somehow causing an increase in the cycles/instruction of somewhere around 2-7% (seems to vary quite a lot from test to test). The working theory is that the CPU's pipeline is getting upset about the call->call->locked-op->return->return, and seems to be failing to speculate (though I haven't seen anything definitive about the precise reasons). This doesn't entirely make sense, because the performance hit is also visible on unlock and other operations which don't involve locked instructions. But spinlock operations clearly swamp all the other pvops operations, even though I can't imagine that they're nearly as common (there's only a .05% increase in instructions executed). If I disable just the pv-spinlock calls, my tests show that pvops is identical to non-pvops performance on native (my measurements show that it is actually about .1% faster, but Xiaohui shows a .05% slowdown). Summary of results, averaging 10 runs of the "mmperf" test, using a no-pvops build as baseline: nopv Pv-nospin Pv-spin CPU cycles 100.00% 99.89% 102.18% instructions 100.00% 100.10% 100.15% CPI 100.00% 99.79% 102.03% cache ref 100.00% 100.84% 100.28% cache miss 100.00% 90.47% 88.56% cache miss rate 100.00% 89.72% 88.31% branches 100.00% 99.93% 100.04% branch miss 100.00% 103.66% 107.72% branch miss rt 100.00% 103.73% 107.67% wallclock 100.00% 99.90% 102.20% The clear effect here is that the 2% increase in CPI is directly reflected in the final wallclock time. (The other interesting effect is that the more ops are out of line calls via pvops, the lower the cache access and miss rates. Not too surprising, but it suggests that the non-pvops kernel is over-inlined. On the flipside, the branch misses go up correspondingly...) So, what's the fix? Paravirt patching turns all the pvops calls into direct calls, so _spin_lock etc do end up having direct calls. For example, the compiler generated code for paravirtualized _spin_lock is: <_spin_lock+0>: mov %gs:0xb4c8,%rax <_spin_lock+9>: incl 0xffffffffffffe044(%rax) <_spin_lock+15>: callq *0xffffffff805a5b30 <_spin_lock+22>: retq The indirect call will get patched to: <_spin_lock+0>: mov %gs:0xb4c8,%rax <_spin_lock+9>: incl 0xffffffffffffe044(%rax) <_spin_lock+15>: callq <__ticket_spin_lock> <_spin_lock+20>: nop; nop /* or whatever 2-byte nop */ <_spin_lock+22>: retq One possibility is to inline _spin_lock, etc, when building an optimised kernel (ie, when there's no spinlock/preempt instrumentation/debugging enabled). That will remove the outer call/return pair, returning the instruction stream to a single call/return, which will presumably execute the same as the non-pvops case. The downsides arel 1) it will replicate the preempt_disable/enable code at eack lock/unlock callsite; this code is fairly small, but not nothing; and 2) the spinlock definitions are already a very heavily tangled mass of #ifdefs and other preprocessor magic, and making any changes will be non-trivial. The other obvious answer is to disable pv-spinlocks. Making them a separate config option is fairly easy, and it would be trivial to enable them only when Xen is enabled (as the only non-default user). But it doesn't really address the common case of a distro build which is going to have Xen support enabled, and leaves the open question of whether the native performance cost of pv-spinlocks is worth the performance improvement on a loaded Xen system (10% saving of overall system CPU when guests block rather than spin). Still it is a reasonable short-term workaround.

The uarts available in the ep93xx have individual clock controls. The current implementation assumes that the bootloader has enabled the clocks before the kernel has booted. It also assumes that the bootloader has set the UARTBAUD bit indicating that the uarts are running off the 14.7456MHz external crystal. This fixes both issues. It also allows the uart clocks to be stopped when there are no users.

Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.

In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN.

That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close().

It also includes a fix for a bogus NULL pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted. It's possible for CIFSSMBQueryUnixSymLink to return without setting target_path to a valid pointer. If that happens then the current value to which we're initializing this pointer could cause an oops when it's kfree'd. This patch is a little more comprehensive than the last patches. It reorganizes cifs_follow_link a bit for (hopefully) better readability. It should also eliminate the uneeded allocation of full_path on servers without unix extensions (assuming they can get to this point anyway, of which I'm not convinced). On a side note, I'm not sure I agree with the logic of enabling this query even when unix extensions are disabled on the client. It seems like that should disable this as well. But, changing that is outside the scope of this fix, so I've left it alone for now.

This is nice and fast, but won't work well if memory is fragmented, since the slab allocator works with physically contiguous memory (i.e. order > 2 allocations are likely to fail fairly early after booting and doing some work). This patch works around the issue by falling back to vmalloc for >PAGE_SIZE allocations. This is ugly, but much less work than chaining a bunch of pages together by hand (suprisingly there's not a bunch of generic kernel helpers for this yet afaik). vmalloc space is somewhat precious on 32 bit kernels, but our allocations shouldn't be big enough to cause problems, though they're routinely more than a page. Note that this patch doesn't address the unchecked alloc-based-on-ioctl-args in GEM; that needs to be fixed in a separate patch. Also, I've deliberately ignored the DRM's "area" junk. I don't think anyone actually uses it anymore and I'm hoping it gets ripped out soon. [Updated: removed size arg to new free function. We could unify the free functions as well once the DRM mem tracking is ripped out.] fd.o bug #20152 (part 1/3) Signed-off-by: Jesse Barnes Signed-off-by: Eric Anholt --- drivers/gpu/drm/i915/i915_gem.c | 38 +++++++++++++-------------------- include/drm/drmP.h | 24 +++++++++++++++++++++ 2 files changed, 39 insertions(+), 23 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index b189b49c760..4a24c90fb94 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -349,7 +349,7 @@ i915_gem_shmem_pread_slow(struct drm_device *dev, struct drm_gem_object *obj, last_data_page = (data_ptr + args->size - 1) / PAGE_SIZE;

The eventual fault was fixed up by futex_handle_fault() which walked the VMA with mmap_sem held. After the cleanup patches which removed the mmap_sem dependency of the futex code commit 4dc5b7a36a49eff97050894cf1b3a9a02523717 (futex: clean up fault logic) removed the private VMA walk logic from the futex code. This change results in a stale RO mapping which is not fixed up. Instead of reintroducing the previous fault logic we set up the mapping in get_user_pages_fast() read/write for all operations which modify user space data. Also handle private futexes in the same way and make the current unconditional access_ok(VERIFY_WRITE) depend on the futex op.

The failure scenario in the kexec case is the following: * Assume a PCI device is not power-manageable by the platform and has PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR. * The device is put into D3 before kexec (using the native PCI PM). * After kexec, pci_setup_device() sets the device's power state to PCI_UNKNOWN. * pci_set_power_state(dev, PCI_D0) is called by the device's driver. * __pci_start_power_transition(dev, PCI_D0) is called and since the device is not power-manageable by the platform, it causes pci_update_current_state(dev, PCI_D0) to be called. As a result the device's current_state field is updated to PCI_D3, in accordance with the contents of its PCI PM registers. * pci_raw_set_power_state() is called and it changes the device power state to D0. *However*, it should also call pci_restore_bars() to reinitialize the device, but it doesn't, because the device's current_state field has been modified earlier. To prevent this from happening, modify pci_platform_power_transition() so that it doesn't use pci_update_current_state() to update the current_state field for devices that aren't power-manageable by the platform. Instead, this field should be updated directly for devices that don't support the native PCI PM. Signed-off-by: Rafael J.

This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

Therefore, we have this layout: extra: +-------------------------+ | struct iw_encode_ext { | | ... | | u16 key_len; | | u8 key[0]; | | }; | +-------------------------+ | key material | +-------------------------+ Now, all drivers I checked use ext->key_len without checking that both key_len and the struct fit into the extra buffer that has been copied from userspace. This leads to a buffer overrun while reading that buffer, depending on the driver it may be possible to specify arbitrary key_len or it may need to be a proper length for the key algorithm specified. Thankfully, this is only exploitable by root, but root can actually cause a segfault or use kernel memory as a key (which you can even get back with siocgiwencode or siocgiwencodeext from the key buffer). Fix this by verifying that key_len fits into the buffer along with struct iw_encode_ext. Signed-off-by: Johannes Berg Signed-off-by: John W.

As explained by Johannes Berg A - lock T - timer phase CPU 1 CPU 2 --------------------------------------------- some place that calls cancel_timer_sync() (which is the | code) lock-irq(A) | "lock-irq"(T) | "unlock"(T) | wait(T) unlock(A) timer softirq "lock"(T) run(T) "unlock"(T) irq handler lock(A) unlock(A) Now all that again, interleaved, leading to deadlock: lock-irq(A) "lock"(T) run(T) IRQ during or maybe before run(T) --> lock(A) "lock-irq"(T) wait(T) We fix this by moving the call to cancel_delayed_work() into workqueue. There are cases where the work may not actually be queued or running at the time we are trying to cancel it, but cancel_delayed_work() is able to deal with this. Also cleanup iwl_set_mode related to this call. This function (iwl_set_mode) is only called when bringing interface up and there will thus not be any scanning done. No need to try to cancel scanning.

Lukyanov found a regression in 2.6.29 and made a complete analysis found in http://bugzilla.kernel.org/show_bug.cgi?id=13339 Quoted here because its a perfect one : begin_of_quotation 2.6.29 patch has introduced flexible route cache rebuilding. Unfortunately the patch has at least one critical flaw, and another problem. rt_intern_hash calculates rthi pointer, which is later used for new entry insertion. The same loop calculates cand pointer which is used to clean the list. If the pointers are the same, rtable leak occurs, as first the cand is removed then the new entry is appended to it. This leak leads to unregister_netdevice problem (usage count > 0). Another problem of the patch is that it tries to insert the entries in certain order, to facilitate counting of entries distinct by all but QoS parameters. Unfortunately, referencing an existing rtable entry moves it to list beginning, to speed up further lookups, so the carefully built order is destroyed. For the first problem the simplest patch it to set rthi=0 when rthi==cand, but it will also destroy the ordering. end_of_quotation Problematic commit is 1080d709fb9d8cd4392f93476ee46a9d6ea05a5b (net: implement emergency route cache rebulds when gc_elasticity is exceeded) Trying to keep dst_entries ordered is too complex and breaks the fact that order should depend on the frequency of use for garbage collection. A possible fix is to make rt_intern_hash() simpler, and only makes rt_check_expire() a litle bit smarter, being able to cope with an arbitrary entries order. The added loop is running on cache hot data, while cpu is prefetching next object, so should be unnoticied. Reported-and-analyzed-by: Alexander V.

For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is rejected (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

When fsl_dma_tx_submit() is run, it only assigns a cookie to the first descriptor. All of the remaining descriptors keep their original value, including the last descriptor, which is set to -EBUSY. After the DMA completes, the driver will update the last completed cookie to be -EBUSY, which is an error code instead of a valid cookie. This causes dma_async_is_complete() to always return DMA_IN_PROGRESS. This causes the fsldma driver to never cleanup the queue of link descriptors, and the driver will re-run the DMA transaction on the hardware each time it receives the End-of-Chain interrupt. This causes an infinite loop. With this patch, fsl_dma_tx_submit() is changed to assign a cookie to every descriptor in the chain. The rest of the code then works without problems.

At least one vendor actively set all the flags to zero, but left ECX on return at 24. This bug may be present in other BIOSes. The breakage functionally means the ACPI 3 flags are probably completely useless, and that no OS any time soon is going to rely on their existence. Therefore, drop support completely. We may want to revisit this question in the future, if we find ourselves actually needing the flags. This reverts all or part of the following checkins: cd670599b7b00d9263f6f11a05c0edeb9cbedaf3 c549e71d073a6e9a4847497344db28a784061455 However, retain the part from the latter commit that copies e820 into a temporary buffer; that is an unrelated BIOS workaround. Put in a comment to explain that part. See https://bugzilla.redhat.com/show_bug.cgi?id=499396 for some additional information.

As the connector type_id is coupled to the connector type, the connector type cannot simply be modified on an initialised connector. This patch changes the order of operations on intel_sdvo_init so that the type is determined before the connector is intialised. This fixes a bug whereby the name card0-VGA-1 would be allocted to both a CRT and an SDVO connector since the SDVO connector would be initialised with type 'unknown' and hence have its type_id assigned from the wrong pool.

Previously, we would set the control bus switch before calls were made to request EDID information over DDC. But recently the DDC code started doing multiple I2C transfers to get the EDID extensions as well. This tripped up SDVO, because the control bus switch is only in effect until the next STOP after a START.

After discussion yesteday on samba-technical about the posix lookup regression, and looking at a problem with cifs posix open to one particular Samba version, Jeff and JRA realized that Samba server's behavior changed in this area (posix open behavior on files vs. directories). To make this behavior consistent, JRA just made a fix to Samba server to alter how it handles open of directories (now returning the equivalent of EISDIR instead of success). Since we don't know at lookup time whether the inode is a directory or file (and thus whether posix open will succeed with most current Samba server), this change avoids the posix open code on lookup open (just issues posix open on creates). This gets the semantic benefits we want (atomicity, posix byte range locks, improved write semantics on newly created files) and file create still is fast, and we avoid the problem that Jeff noticed yesterday with "openat" (and some open directory calls) of non-cached directories to one version of Samba server, and will work with future Samba versions (which include the fix jra just pushed into Samba server). I confirmed this approach with jra yesterday and with Shirish today. Posix open is only called (at lookup time) for file create now. For opens (rather than creates), because we do not know if it is a file or directory yet, and current Samba no longer allows us to do posix open on dirs, we could end up wasting an open call on what turns out to be a dir. For file opens, we wait to call posix open till cifs_open. It could be added here (lookup) in the future but the performance tradeoff of the extra network request when EISDIR or EACCES is returned would have to be weighed against the 50% reduction in network traffic in the other paths.

The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done twice on skbuffs recycled in this way, causing there not to be enough room in the skb anymore to receive a full packet, eventually leading to an skb_over_panic from gfar_clean_rx_ring() -> skb_put(). Resetting the skb->data pointer to skb->head + NET_SKB_PAD before putting the skb back onto the recycle list restores the mentioned invariant, and should fix this issue.

Thus the conntrack entry is destroyed but the destination retransmits data until timeout. The same technique, i.e. sending properly crafted RST segments, can easily be used to bypass connlimit/connbytes based restrictions (the sample script written by Robert can be found in the netfilter mailing list archives). The patch below adds a new flag and new field to struct ip_ct_tcp_state so that checking RST segments can be made more strict and thus TCP conntrack can catch the invalid ones: the RST segment is accepted only if its sequence number higher than or equal to the highest ack we seen from the other direction. (The last_ack field cannot be reused because it is used to catch resent packets.)

This triggered while booting an F11 PAE kernel; the futex initialization code runs before any CR3 reloads and writes to a NULL pointer; the futex subsystem ended up uninitialized, killing PI futexes and pulseaudio which uses them.

The kernel image is one statically linked object and only uses two relocation types - R_386_PC32 and R_386_32, of the two only the latter needs massaging during kernel relocation and thus handled by relocs. R_386_PC32 is ignored and all other relocation types are considered error. When the target of a relocation resides in a discarded section, binutils doesn't throw away the relocation record but nullifies it by changing it to R_386_NONE, which unfortunately makes relocs fail. The problem was triggered by yet out-of-tree x86 stack unwind patches but given the binutils behavior, ignoring R_386_NONE is the right thing to do. The problem has been tracked down to binutils behavior by Jan Beulich.

If not all of the active events are acknowledged, or a new event becomes active while the existing ones are cleared in the handler, we will not see a new interrupt. The current interrupt handler masks off the Rx and Tx events once the NAPI handler has been scheduled, which opens a race window in which we can get another Rx or Tx event and never ACK'ing it, stopping all activity until the link is reset (ifconfig down/up).

The rwlock seems to be taken around the whole call to cpufreq_governor_dbs(), when it should be only taken around accesses to the locked data, and especially *not* around the call to dbs_timer_exit(). Reverting my fix attempt would put the teardown race back in place (replacing the cancel_delayed_work_sync by cancel_delayed_work). Instead, a proper fix would imply modifying this critical section : cpufreq.c: __cpufreq_remove_dev() ... if (cpufreq_driver->target) __cpufreq_governor(data, CPUFREQ_GOV_STOP); unlock_policy_rwsem_write(cpu); To make sure the __cpufreq_governor() callback is not called with rwsem held. This would allow execution of cancel_delayed_work_sync() without being nested within the rwsem. Applies on top of the 2.6.30-rc5 tree. Required to remove circular dep in teardown of both conservative and ondemande governors so they can use cancel_delayed_work_sync(). CPUFREQ_GOV_STOP does not modify the policy, therefore this locking seemed unneeded. Signed-off-by: Mathieu Desnoyers CC: KOSAKI Motohiro Cc: Greg KH CC: Ingo Molnar CC: "Rafael J.

Currently powernow-k8 determines CPU frequency from ACPI PSS objects, but according to AMD family 11h BKDG this frequency is just a rounded value: "CoreFreq (MHz) = The CPU COF specified by MSRC001_00[6B:64][CpuFid] rounded to the nearest 100 Mhz." As a consequnce powernow-k8 reports wrong CPU frequency on some systems, e.g. on Turion X2 Ultra: powernow-k8: Found 1 AMD Turion(tm)X2 Ultra DualCore Mobile ZM-82 processors (2 cpu cores) (version 2.20.00) powernow-k8: 0 : pstate 0 (2200 MHz) powernow-k8: 1 : pstate 1 (1100 MHz) powernow-k8: 2 : pstate 2 (600 MHz) But this is wrong as frequency for Pstate2 is 550 MHz. x86info reports it correctly: #x86info -a |grep Pstate ... Pstate-0: fid=e, did=0, vid=24 (2200MHz) Pstate-1: fid=e, did=1, vid=30 (1100MHz) Pstate-2: fid=e, did=2, vid=3c (550MHz) (current) Solution is to determine the frequency directly from Pstate MSRs instead of using rounded values from ACPI table.

The pitch field is an exponent on pre-965, so we were rejecting buffers on 8xx that we shouldn't have. 915 got lucky in that the largest legal value happened to match (8KB / 512 = 0x10), but 8xx has a smaller tile width. Additionally, we programmed that bad value into the register on 8xx, so the only pitch that would work correctly was 4096 (512-1023 pixels), while others would probably give bad rendering or hangs.

On the 865, but not the 855, the clflush we do appears to not actually make it out to the hardware all the time. An easy way to safely reproduce was X -retro, which would show that some of the blits involved in drawing the lovely root weave didn't make it out to the hardware. Those blits are 32 bytes each, and 1-2 would be missing at various points around the screen. Other experimentation (doing more clflush, doing more AGP chipset flush, poking at some more device registers to maybe trigger more flushing) didn't help. krh came up with the wbinvd as a way to successfully get all those blits to appear.

While it was a good idea to try to use the mm/vmalloc.c allocator instead of our own (in fact, ours is itself a dup on an old variant of the vmalloc one), unfortunately, the approach is terminally busted since dma_alloc_coherent() can be called at interrupt time or in atomic contexts and there's little chances we'll make the code in mm/vmalloc.c cope with\ that :-( Until we can get the generic code to forbid that idiocy and fix all drivers abusing it, we pretty much have no choice but revert to our custom virtual space allocator. There's also a problem with SMP safety since freeing such mapping would require an IPI which cannot be done at interrupt time. However, right now, I don't think we support any platform that is both SMP and has non-coherent DMA (don't laugh, I know such things do exist !) so we can sort that out later.

The implementation we just revived has issues, such as using a Kconfig-defined virtual address area in kernel space that nothing actually carves out (and thus will overlap whatever is there), or having some dependencies on being self contained in a single PTE page which adds unnecessary constraints on the kernel virtual address space. This fixes it by using more classic PTE accessors and automatically locating the area for consistent memory, carving an appropriate hole in the kernel virtual address space, leaving only the size of that area as a Kconfig option. It also brings some dma-mask related fixes from the ARM implementation which was almost identical initially but grew its own fixes.

The pci_dev struct itself wasn't deallocated because acpiphp kept a reference, but some of its fields became invalid. acpiphp doesn't have any real reason to keep a pointer to a pci_dev around.

The svcrdma module was incorrectly unmapping the RPCRDMA header page. On IBM pserver systems this causes a resource leak that results in running out of bus address space (10 cthon iterations will reproduce it). The code was mapping the full page but only unmapping the actual header length. The fix is to only map the header length. I also cleaned up the use of ib_dma_map_page() calls since the unmap logic always uses ib_dma_unmap_single(). I made these symmetrical.

Since operand lengths other than 32bit are required, the full implementations are only available if the ARMv6K extensions are present (for the LDREXB, LDREXH and LDREXD instructions). For ARMv6, only 32-bits cmpxchg is available. Mathieu : Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes). Make cmpxchg64_local always available. Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does. Change since v3 : - Add "memory" clobbers (thanks to Nicolas Pitre) - removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+. Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not supported by the Linux kernel currently. Put back arm < v6 cmpxchg support.

The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

A larger patch (f7e7aa585) a few days after this one added the same line to the Makefile, but in a different place. While it'd be more correct to revert that one, it's easier to revert this one because this is a one-liner.

Replace that build-time scheme with a load-time module parameter: "7300_idle.forceload=1" to make it easier to test the driver on hardware that while not officially validated, works fine and is much more commonly available. By default (no modparam) the driver will continue to load only on the i7300. Note that ioat_dma runs a copy of i7300_idle's probe routine to know to reserve an IOAT channel for i7300_idle. This change makes ioat_dma do that always on the i5000, just like it does on the i7300.

These functions being meaningless on x86 (if CONFIG_DMA_API_DEBUG is not set). The HW ends up with a bogus bus address. This patch saves the page buffer bus address for all plaftorms.

Subject: [PATCH 0889/1012] mtd: MXC NAND driver fixes (v5) The following patch fixes: - re-initialization of host->col_addr which is used as byte index between the successive READID flash commands. - compile error when CONFIG_PM is enabled - pass on the error code from clk_get() - return -ENOMEM in case of failed ioremap() - pass on the return value of platform_driver_probe() directly - remove excessive printk - let command line partition table parsing with mxc_nand name. The cmd_line parsing is done via name that differs from mxc_nand by default and looks like "NAND 256MiB 1,8V 8-bit" Signed-off-by: Vladimir Barinov Signed-off-by: Lothar Wassmann Acked-by: Sascha Hauer Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse --- drivers/mtd/nand/mxc_nand.c | 43 ++++++++++++++++++++----------------- 1 file changed, 23 insertions(+), 20 deletions(-) diff --git a/drivers/mtd/nand/mxc_nand.c b/drivers/mtd/nand/mxc_nand.c index f3548d04801..40c26080ecd 100644 --- a/drivers/mtd/nand/mxc_nand.c +++ b/drivers/mtd/nand/mxc_nand.c @@ -831,6 +831,7 @@ static void mxc_nand_command(struct mtd_info *mtd, unsigned command, break; case NAND_CMD_READID: + host->col_addr = 0; send_read_id(host); break; @@ -867,6 +868,7 @@ static int __init mxcnd_probe(struct platform_device *pdev) mtd->priv = this; mtd->owner = THIS_MODULE; mtd->dev.parent = &pdev->dev; + mtd->name = "mxc_nand"; /* 50 us command delay time */ this->chip_delay = 5; @@ -882,8 +884,10 @@ static int __init mxcnd_probe(struct platform_device *pdev) this->verify_buf = mxc_nand_verify_buf; host->clk = clk_get(&pdev->dev, "nfc"); - if (IS_ERR(host->clk)) + if (IS_ERR(host->clk)) { + err = PTR_ERR(host->clk); goto eclk; + } clk_enable(host->clk); host->clk_act = 1; @@ -896,7 +900,7 @@ static int __init mxcnd_probe(struct platform_device *pdev) host->regs = ioremap(res->start, res->end - res->start + 1); if (!host->regs) { - err = -EIO; + err = -ENOMEM; goto eres; } @@ -1011,30 +1015,35 @@ static int __devexit mxcnd_remove(struct platform_device *pdev) #ifdef CONFIG_PM static int mxcnd_suspend(struct platform_device *pdev, pm_message_t state) { - struct mtd_info *info = platform_get_drvdata(pdev); + struct mtd_info *mtd = platform_get_drvdata(pdev); + struct nand_chip *nand_chip = mtd->priv; + struct mxc_nand_host *host = nand_chip->priv; int ret = 0; DEBUG(MTD_DEBUG_LEVEL0, "MXC_ND : NAND suspend\n"); - if (info) - ret = info->suspend(info); - - /* Disable the NFC clock */ - clk_disable(nfc_clk); /* FIXME */ + if (mtd) { + ret = mtd->suspend(mtd); + /* Disable the NFC clock */ + clk_disable(host->clk); + } return ret; } static int mxcnd_resume(struct platform_device *pdev) { - struct mtd_info *info = platform_get_drvdata(pdev); + struct mtd_info *mtd = platform_get_drvdata(pdev); + struct nand_chip *nand_chip = mtd->priv; + struct mxc_nand_host *host = nand_chip->priv; int ret = 0; DEBUG(MTD_DEBUG_LEVEL0, "MXC_ND : NAND resume\n"); - /* Enable the NFC clock */ - clk_enable(nfc_clk); /* FIXME */ - if (info) - info->resume(info); + if (mtd) { + /* Enable the NFC clock */ + clk_enable(host->clk); + mtd->resume(mtd); + } return ret; } @@ -1055,13 +1064,7 @@ static struct platform_driver mxcnd_driver = { static int __init mxc_nd_init(void) { - /* Register the device driver structure. */ - pr_info("MXC MTD nand Driver\n"); - if (platform_driver_probe(&mxcnd_driver, mxcnd_probe) != 0) { - printk(KERN_ERR "Driver register failed for mxcnd_driver\n"); - return -ENODEV; - } - return 0; + return platform_driver_probe(&mxcnd_driver, mxcnd_probe); } static void __exit mxc_nd_cleanup(void) -- GitLab From 81e2962801bbb4e740c501ca687d5cb857929c04 Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Thu, 28 May 2009 17:43:59 +0200 Subject: [PATCH 0890/1012] jffs2: Fix corruption when flash erase/write failure Erase errors such as: "Newly-erased block contained word 0xa4ef223e at offset 0x0296a014" and failure to write the clean marker, moves the offending erase block to erasing list before calling jffs2_erase_failed().

However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

As part of this, page_table_shareable() checks a pair of vma->vm_flags and they must match if they are to be shared. All VMA flags are taken into account, including VM_LOCKED. The problem is that VM_LOCKED is cleared on fork(). When a process with a shared memory segment forks() to exec() a helper, there will be shared VMAs with different flags. The impact is that the shared segment is sometimes considered shareable and other times not, depending on what process is checking. What happens is that the segment page tables are being shared but the count is inaccurate depending on the ordering of events. As the page tables are freed with put_page(), bad pmd's are found when some of the children exit. The hugepage counters also get corrupted and the Total and Free count will no longer match even when all the hugepage-backed regions are freed. This requires a reboot of the machine to "fix". This patch addresses the problem by comparing all flags except VM_LOCKED when deciding if pagetables should be shared or not for hugetlbfs-backed mapping.

The reservation behaviour differs depending on whether the mapping was mapped MAP_SHARED or MAP_PRIVATE. For MAP_SHARED mappings, hugepages are reserved when mmap() is first called and are tracked based on information associated with the inode. Other processes mapping MAP_SHARED use the same reservation. MAP_PRIVATE track the reservations based on the VMA created as part of the mmap() operation. Each process mapping MAP_PRIVATE must make its own reservation. hugetlbfs currently checks if a VMA is MAP_SHARED with the VM_SHARED flag and not VM_MAYSHARE. For file-backed mappings, such as hugetlbfs, VM_SHARED is set only if the mapping is MAP_SHARED and the file was opened read-write. If a shared memory mapping was mapped shared-read-write for populating of data and mapped shared-read-only by other processes, then hugetlbfs would account for the mapping as if it was MAP_PRIVATE. This causes processes to fail to map the file MAP_SHARED even though it should succeed as the reservation is there. This patch alters mm/hugetlb.c and replaces VM_SHARED with VM_MAYSHARE when the intent of the code was to check whether the VMA was mapped MAP_SHARED or MAP_PRIVATE.

So disregard a _PSS with a frequency so large that it can't be represented by cpufreq. https://bugzilla.redhat.com/show_bug.cgi?id=500311 Signed-off-by: Len Brown --- drivers/acpi/processor_perflib.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/drivers/acpi/processor_perflib.c b/drivers/acpi/processor_perflib.c index cafb41000f6..60e543d3234 100644 --- a/drivers/acpi/processor_perflib.c +++ b/drivers/acpi/processor_perflib.c @@ -309,9 +309,15 @@ static int acpi_processor_get_performance_states(struct acpi_processor *pr) (u32) px->bus_master_latency, (u32) px->control, (u32) px->status)); - if (!px->core_frequency) { - printk(KERN_ERR PREFIX - "Invalid _PSS data: freq is zero\n"); + /* + * Check that ACPI's u64 MHz will be valid as u32 KHz in cpufreq + */ + if (!px->core_frequency || + ((u32)(px->core_frequency * 1000) != + (px->core_frequency * 1000))) { + printk(KERN_ERR FW_BUG PREFIX + "Invalid BIOS _PSS frequency: 0x%llx MHz\n", + px->core_frequency); result = -EFAULT; kfree(pr->performance->states); goto end; -- GitLab From 34ac272b3aaef11a91e19a72f3ac5772a96ffbc5 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 26 May 2009 23:35:34 -0400 Subject: [PATCH 0913/1012] ACPI: video: DMI workaround broken eMachines E510 BIOS enabling display brightness http://bugzilla.kernel.org/show_bug.cgi?id=13376 Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/video.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index 810cca90ca7..ee45e760422 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -570,6 +570,14 @@ static struct dmi_system_id video_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "Aspire 5710Z"), }, }, + { + .callback = video_set_bqc_offset, + .ident = "eMachines E510", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "EMACHINES"), + DMI_MATCH(DMI_PRODUCT_NAME, "eMachines E510"), + }, + }, {} }; -- GitLab From 93bcece20ef87c29548ec7e66532f1018572cea0 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 19 May 2009 15:08:41 -0400 Subject: [PATCH 0914/1012] ACPI: video: DMI workaround broken Acer 5315 BIOS enabling display brightness http://bugzilla.kernel.org/show_bug.cgi?id=13121 Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/video.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index ee45e760422..6d897bbd3bd 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -578,6 +578,14 @@ static struct dmi_system_id video_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "eMachines E510"), }, }, + { + .callback = video_set_bqc_offset, + .ident = "Acer Aspire 5315", + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "Acer"), + DMI_MATCH(DMI_PRODUCT_NAME, "Aspire 5315"), + }, + }, {} }; -- GitLab From 1fc8d33acafe68bdcc21b327d22ef3820b819727 Mon Sep 17 00:00:00 2001 From: Jaswinder Singh Rajput Date: Wed, 20 May 2009 11:56:08 +0530 Subject: [PATCH 0915/1012] drm/i915: acpi/video.c fix section mismatch warning Currently acpi_video_exit() is exported as well as using __exit which causes: WARNING: drivers/acpi/video.o(__ksymtab+0x0): Section mismatch in reference from the variable __ksymtab_acpi_video_exit to the function .exit.text:acpi_video_exit() The symbol acpi_video_exit is exported and annotated __exit Fix this by removing the __exit annotation of acpi_video_exit or drop the export.

That resulted in xfs_fsr deadlocking itself on platforms, which don't handle double unlock of rw_semaphore nicely. It caused the count go negative, which represents the write holder, without really having one. ia64 is one of the platforms where deadlock was easily reproduced and the fix was tested.

The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000.

When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops.

This patch changes this - we check the variant and revision fields in the main ID register to determine which errata to apply. We also avoid re-applying erratum 460075 if it has already been applied. Applying this fix in non-secure mode results in the kernel failing to boot (or even do anything.) This fixes booting on some ARMv7 based platforms which otherwise silently fail.

However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away.

Add drm_helper_connector_dpms. Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

It starts off with a hint to help find the best block group for a given allocation. The hint is resolved into a block group, but we don't properly check to make sure the block group we find isn't in the middle of being freed due to filesystem shrinking or balancing. If it is being freed, the list pointers in it are bogus and can't be trusted. But, the code happily goes along and uses them in the list_for_each loop, leading to all kinds of fun. The fix used here is to check to make sure the block group we find really is on the list before we use it. list_del_init is used when removing it from the list, so we can do a proper check. The allocation clustering code has a similar bug where it will trust the block group in the current free space cluster. If our allocation flags have changed (going from single spindle dup to raid1 for example) because the drives in the FS have changed, we're not allowed to use the old block group any more. The fix used here is to check the current cluster against the current allocation flags.

Stracing dd reveals that it first does an mmap2, which makes 1GB worth of zero page mappings. Then it performs a read on those pages from /dev/zero, and finally it performs a write. The machine died during the reads. Looking at the code, it was noticed that /dev/zero's read operation had been changed by 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving zero page mappings to actually zeroing the page. The zeroing of the pages causes physical pages to be allocated to the process. But, when the process exhausts all the memory that it can, the kernel cannot kill it, as it is still in the kernel mode allocating more memory. Consequently, the kernel eventually crashes. To fix this, I propose that when a fatal signal is pending during /dev/zero read operation, we simply return and let the user process die.

I believe the changelog is right and this wake_up() is wrong in many ways, but GDB assumes that ptrace(PTRACE_DETACH, child, 0, 0) always wakes up the tracee. Despite the fact this breaks SIGNAL_STOP_STOPPED/group_stop_count logic, and despite the fact this wake_up_process() can break another assumption: PTRACE_DETACH with SIGSTOP should leave the tracee in TASK_STOPPED case. Because the untraced child can dequeue SIGSTOP and call do_signal_stop() before ptrace_detach() calls wake_up_process(). Revert this change for now.

Of these three, only ext2 and jfs's get_block() function pays attention to bh->b_size --- which is normally always the filesystem blocksize except when the get_block() function is called by either mpage_readpage(), mpage_readpages(), or the direct I/O routines in fs/direct_io.c. Unfortunately, nobh_truncate_page() does not initialize map_bh before calling the filesystem-supplied get_block() function. So ext2 and jfs will try to calculate the number of blocks to map by taking stack garbage and shifting it left by inode->i_blkbits. This should be *mostly* harmless (except the filesystem will do some unnneeded work) unless the stack garbage is less than filesystem's blocksize, in which case maxblocks will be zero, and the attempt to find out whether or not the filesystem has a hole at a given logical block will fail, and the page cache entry might not get zero'ed out. Also if the stack garbage in in map_bh->state happens to have the BH_Mapped bit set, there could be an attempt to call readpage() on a non-existent page, which could cause nobh_truncate_page() to return an error when it should not. Fix this by initializing map_bh->state and map_bh->size. Fortunately, it's probably fairly unlikely that ext2 and jfs users mount with nobh these days.

The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

This caused things like no being able to read the root filesystem, resulting in missing console devices and inability to run 'init', causing a boot-time panic. This fixes it by properly returning the lowest pending async ID: if there is any running async work, that will have a lower ID than any pending work, and we should _not_ look at the pending work list. There were alternative patches from Jaswinder and James, but this one also cleans up the code by removing the pointless 'ret' variable and the unnecesary testing for an empty list around 'for_each_entry()' (if the list is empty, the for_each_entry() thing just won't execute).

This is used to achieve a stable state before making internal changes. Currently this quiescing applies equally to normal IO, resync IO, and reshape IO. However there is a problem with applying it to reshape IO. Reshape can have multiple 'stripe_heads' that must be active together. If the quiesce come between allocating the first and the last of such a collection, then we deadlock, as the last will not be allocated until the quiesce is lifted, the quiesce will not be lifted until the first (which has been allocated) gets used, and that first cannot be used until the last is allocated. It is not necessary to inhibit reshape IO when a quiesce is requested. Those places in the code that require a full quiesce will ensure the reshape thread is not running at all. So allow reshape requests to get access to new stripe_heads without being blocked by a 'quiesce'. This only affects in-place reshapes (i.e. where the array does not grow or shrink) and these are only newly supported. So this patch is not needed in earlier kernels.

( original thread at http://lkml.org/lkml/2009/6/8/192 ) Problem is this driver tells that NIC frames up to 16383 bytes can be received but provides skb to rx ring allocated with smaller sizes (1536 bytes in case standard 1500 bytes MTU is used) When a frame larger than what was allocated by driver is received, dma transfert can occurs past the end of buffer and corrupt kernel memory. Fix is to tell to NIC what is the maximum size a frame can be. This bug is very old, (before git introduction, linux-2.6.10), and should be backported to stable versions.

We were concerned about side effects from this change and one has been identified. I saw several error messages. They cause autofs to become quite confused and don't really point to the actual problem. Things like: handle_packet_missing_direct:1376: can't find map entry for (43,1827932) which is usually totally fatal (although in this case it wouldn't be except that I treat is as such because it normally is). do_mount_direct: direct trigger not valid or already mounted /test/nested/g3c/s1/ss1 which is recoverable, however if this problem is at play it can cause autofs to become quite confused as to the dependencies in the mount tree because mount triggers end up mounted multiple times. It's hard to accurately check for this over mounting case and automount shouldn't need to if the kernel module is doing its job. There was one other message, similar in consequence of this last one but I can't locate a log example just now. When checking if a mount has already completed prior to adding a new mount request to the wait queue we check if the dentry is hashed and, if so, if it is a mount point. But, if a mount successfully completed while we slept on the wait queue mutex the dentry must exist for the mount to have completed so the test is not really needed. Mounts can also be done on top of a global root dentry, so for the above case, where a mount request completes and the wait queue entry has already been removed, the hashed test returning false can cause an incorrect callback to the daemon. Also, d_mountpoint() is not sufficient to check if a mount has completed for the multi-mount case when we don't have a real mount at the base of the tree.

During this scan, we sometimes have to drop j_list_lock and then we recheck whether the journal buffer head didn't get freed by journal_try_to_free_buffers(). But checking for buffer_jbd(bh) isn't enough because a new journal head could get attached to our buffer head. So add a check whether the journal head remained the same and whether it's still at the same transaction and list. This is a nasty bug and can cause problems like memory corruption (use after free) or trigger various assertions in JBD code (observed).
