SCSI commands + are 6, 10, 12, or 16 bytes long, often followed by an associated data + payload. + + + SCSI commands can be transported over just about any kind of bus, and + are the default protocol for storage devices attached to USB, SATA, + SAS, Fibre Channel, FireWire, and ATAPI devices. SCSI packets are + also commonly exchanged over Infiniband, + I20, TCP/IP + (iSCSI), even + Parallel + ports. + + + + Design of the Linux SCSI subsystem + + The SCSI subsystem uses a three layer design, with upper, mid, and low + layers. Every operation involving the SCSI subsystem (such as reading + a sector from a disk) uses one driver at each of the 3 levels: one + upper layer driver, one lower layer driver, and the SCSI midlayer. + + + The SCSI upper layer provides the interface between userspace and the + kernel, in the form of block and char device nodes for I/O and + ioctl(). The SCSI lower layer contains drivers for specific hardware + devices. + + + In between is the SCSI mid-layer, analogous to a network routing + layer such as the IPv4 stack. The SCSI mid-layer routes a packet + based data protocol between the upper layer's /dev nodes and the + corresponding devices in the lower layer. It manages command queues, + provides error handling and power management functions, and responds + to ioctl() requests. + + + + + + SCSI upper layer + + The upper layer supports the user-kernel interface by providing + device nodes. + + + sd (SCSI Disk) + sd (sd_mod.o) + + + + sr (SCSI CD-ROM) + sr (sr_mod.o) + + + st (SCSI Tape) + st (st.o) + + + sg (SCSI Generic) + sg (sg.o) + + + ch (SCSI Media Changer) + ch (ch.c) + + + + + SCSI mid layer + + + SCSI midlayer implementation + + include/scsi/scsi_device.h + + +!Iinclude/scsi/scsi_device.h + + + + drivers/scsi/scsi.c + Main file for the SCSI midlayer. +!Edrivers/scsi/scsi.c + + + drivers/scsi/scsicam.c + + SCSI + Common Access Method support functions, for use with + HDIO_GETGEO, etc. + +!Edrivers/scsi/scsicam.c + + + drivers/scsi/scsi_error.c + Common SCSI error/timeout handling routines. +!Edrivers/scsi/scsi_error.c + + + drivers/scsi/scsi_devinfo.c + + Manage scsi_dev_info_list, which tracks blacklisted and whitelisted + devices. + +!Idrivers/scsi/scsi_devinfo.c + + + drivers/scsi/scsi_ioctl.c + + Handle ioctl() calls for SCSI devices. + +!Edrivers/scsi/scsi_ioctl.c + + + drivers/scsi/scsi_lib.c + + SCSI queuing library. + +!Edrivers/scsi/scsi_lib.c + + + drivers/scsi/scsi_lib_dma.c + + SCSI library functions depending on DMA + (map and unmap scatter-gather lists). + +!Edrivers/scsi/scsi_lib_dma.c + + + drivers/scsi/scsi_module.c + + The file drivers/scsi/scsi_module.c contains legacy support for + old-style host templates.

Dealing with kobjects requires understanding a few different types, +all of which make reference to each other. In an attempt to make things +easier, we'll take a multi-pass approach, starting with vague terms and +adding detail as we go. To that end, here are some quick definitions of +some terms we will be working with. -0. Introduction + - A kobject is an object of type struct kobject. Kobjects have a name + and a reference count. A kobject also has a parent pointer (allowing + objects to be arranged into hierarchies), a specific type, and, + usually, a representation in the sysfs virtual filesystem. -The kobject infrastructure performs basic object management that larger -data structures and subsystems can leverage, rather than reimplement -similar functionality. This functionality primarily concerns: + Kobjects are generally not interesting on their own; instead, they are + usually embedded within some other structure which contains the stuff + the code is really interested in. -- Object reference counting. -- Maintaining lists (sets) of objects. -- Object set locking. -- Userspace representation. + No structure should EVER have more than one kobject embedded within it. + If it does, the reference counting for the object is sure to be messed + up and incorrect, and your code will be buggy. So do not do this. -The infrastructure consists of a number of object types to support -this functionality. Their programming interfaces are described below -in detail, and briefly here: + - A ktype is the type of object that embeds a kobject. Every structure + that embeds a kobject needs a corresponding ktype. The ktype controls + what happens to the kobject when it is created and destroyed. -- kobjects a simple object. -- kset a set of objects of a certain type. -- ktype a set of helpers for objects of a common type. + - A kset is a group of kobjects. These kobjects can be of the same ktype + or belong to different ktypes. The kset is the basic container type for + collections of kobjects. Ksets contain their own kobjects, but you can + safely ignore that implementation detail as the kset core code handles + this kobject automatically. + When you see a sysfs directory full of other directories, generally each + of those directories corresponds to a kobject in the same kset. -The kobject infrastructure maintains a close relationship with the -sysfs filesystem. Each kobject that is registered with the kobject -core receives a directory in sysfs. Attributes about the kobject can -then be exported. Please see Documentation/filesystems/sysfs.txt for -more information. +We'll look at how to create and manipulate all of these types. A bottom-up +approach will be taken, so we'll go back to kobjects. -The kobject infrastructure provides a flexible programming interface, -and allows kobjects and ksets to be used without being registered -(i.e. with no sysfs representation). This is also described later. +Embedding kobjects -1. kobjects +It is rare for kernel code to create a standalone kobject, with one major +exception explained below. Instead, kobjects are used to control access to +a larger, domain-specific object. To this end, kobjects will be found +embedded in other structures. If you are used to thinking of things in +object-oriented terms, kobjects can be seen as a top-level, abstract class +from which other classes are derived. A kobject implements a set of +capabilities which are not particularly useful by themselves, but which are +nice to have in other objects. The C language does not allow for the +direct expression of inheritance, so other techniques - such as structure +embedding - must be used. -1.1 Description +So, for example, the UIO code has a structure that defines the memory +region associated with a uio device: +struct uio_mem { + struct kobject kobj; + unsigned long addr; + unsigned long size; + int memtype; + void __iomem *internal_addr; +}; -struct kobject is a simple data type that provides a foundation for -more complex object types. It provides a set of basic fields that -almost all complex data types share. kobjects are intended to be -embedded in larger data structures and replace fields they duplicate. +If you have a struct uio_mem structure, finding its embedded kobject is +just a matter of using the kobj member. Code that works with kobjects will +often have the opposite problem, however: given a struct kobject pointer, +what is the pointer to the containing structure? You must avoid tricks +(such as assuming that the kobject is at the beginning of the structure) +and, instead, use the container_of() macro, found in : -1.2 Definition + container_of(pointer, type, member) -struct kobject { - const char * k_name; - struct kref kref; - struct list_head entry; - struct kobject * parent; - struct kset * kset; - struct kobj_type * ktype; - struct sysfs_dirent * sd; - wait_queue_head_t poll; -}; +where pointer is the pointer to the embedded kobject, type is the type of +the containing structure, and member is the name of the structure field to +which pointer points. The return value from container_of() is a pointer to +the given type. So, for example, a pointer "kp" to a struct kobject +embedded within a struct uio_mem could be converted to a pointer to the +containing uio_mem structure with: -void kobject_init(struct kobject *); -int kobject_add(struct kobject *); -int kobject_register(struct kobject *); + struct uio_mem *u_mem = container_of(kp, struct uio_mem, kobj); -void kobject_del(struct kobject *); -void kobject_unregister(struct kobject *); +Programmers often define a simple macro for "back-casting" kobject pointers +to the containing type. -struct kobject * kobject_get(struct kobject *); -void kobject_put(struct kobject *); +Initialization of kobjects -1.3 kobject Programming Interface +Code which creates a kobject must, of course, initialize that object. Some +of the internal fields are setup with a (mandatory) call to kobject_init(): -kobjects may be dynamically added and removed from the kobject core -using kobject_register() and kobject_unregister(). Registration -includes inserting the kobject in the list of its dominant kset and -creating a directory for it in sysfs. + void kobject_init(struct kobject *kobj, struct kobj_type *ktype); -Alternatively, one may use a kobject without adding it to its kset's list -or exporting it via sysfs, by simply calling kobject_init(). An -initialized kobject may later be added to the object hierarchy by -calling kobject_add(). An initialized kobject may be used for -reference counting. +The ktype is required for a kobject to be created properly, as every kobject +must have an associated kobj_type. After calling kobject_init(), to +register the kobject with sysfs, the function kobject_add() must be called: -Note: calling kobject_init() then kobject_add() is functionally -equivalent to calling kobject_register(). + int kobject_add(struct kobject *kobj, struct kobject *parent, const char *fmt, ...); -When a kobject is unregistered, it is removed from its kset's list, -removed from the sysfs filesystem, and its reference count is decremented. -List and sysfs removal happen in kobject_del(), and may be called -manually. kobject_put() decrements the reference count, and may also -be called manually. +This sets up the parent of the kobject and the name for the kobject +properly. If the kobject is to be associated with a specific kset, +kobj->kset must be assigned before calling kobject_add(). If a kset is +associated with a kobject, then the parent for the kobject can be set to +NULL in the call to kobject_add() and then the kobject's parent will be the +kset itself. -A kobject's reference count may be incremented with kobject_get(), -which returns a valid reference to a kobject; and decremented with -kobject_put(). An object's reference count may only be incremented if -it is already positive. +As the name of the kobject is set when it is added to the kernel, the name +of the kobject should never be manipulated directly. If you must change +the name of the kobject, call kobject_rename(): -When a kobject's reference count reaches 0, the method struct -kobj_type::release() (which the kobject's kset points to) is called. -This allows any memory allocated for the object to be freed. + int kobject_rename(struct kobject *kobj, const char *new_name); +There is a function called kobject_set_name() but that is legacy cruft and +is being removed. If your code needs to call this function, it is +incorrect and needs to be fixed. -NOTE!!! +To properly access the name of the kobject, use the function +kobject_name(): -It is _imperative_ that you supply a destructor for dynamically -allocated kobjects to free them if you are using kobject reference -counts. The reference count controls the lifetime of the object. -If it goes to 0, then it is assumed that the object will -be freed and cannot be used. + const char *kobject_name(const struct kobject * kobj); -More importantly, you must free the object there, and not immediately -after an unregister call. If someone else is referencing the object -(e.g. through a sysfs file), they will obtain a reference to the -object, assume it's valid and operate on it. If the object is -unregistered and freed in the meantime, the operation will then -reference freed memory and go boom. +There is a helper function to both initialize and add the kobject to the +kernel at the same time, called supprisingly enough kobject_init_and_add(): -This can be prevented, in the simplest case, by defining a release -method and freeing the object from there only. Note that this will not -secure reference count/object management models that use a dual -reference count or do other wacky things with the reference count -(like the networking layer). + int kobject_init_and_add(struct kobject *kobj, struct kobj_type *ktype, + struct kobject *parent, const char *fmt, ...); +The arguments are the same as the individual kobject_init() and +kobject_add() functions described above. -1.4 sysfs -Each kobject receives a directory in sysfs. This directory is created -under the kobject's parent directory. +Uevents -If a kobject does not have a parent when it is registered, its parent -becomes its dominant kset. +After a kobject has been registered with the kobject core, you need to +announce to the world that it has been created. This can be done with a +call to kobject_uevent(): -If a kobject does not have a parent nor a dominant kset, its directory -is created at the top-level of the sysfs partition. + int kobject_uevent(struct kobject *kobj, enum kobject_action action); +Use the KOBJ_ADD action for when the kobject is first added to the kernel. +This should be done only after any attributes or children of the kobject +have been initialized properly, as userspace will instantly start to look +for them when this call happens. +When the kobject is removed from the kernel (details on how to do that is +below), the uevent for KOBJ_REMOVE will be automatically created by the +kobject core, so the caller does not have to worry about doing that by +hand. -2. ksets -2.1 Description +Reference counts -A kset is a set of kobjects that are embedded in the same type. +One of the key functions of a kobject is to serve as a reference counter +for the object in which it is embedded. As long as references to the object +exist, the object (and the code which supports it) must continue to exist. +The low-level functions for manipulating a kobject's reference counts are: + struct kobject *kobject_get(struct kobject *kobj); + void kobject_put(struct kobject *kobj); -struct kset { - struct kobj_type * ktype; - struct list_head list; - struct kobject kobj; - struct kset_uevent_ops * uevent_ops; -}; +A successful call to kobject_get() will increment the kobject's reference +counter and return the pointer to the kobject. +When a reference is released, the call to kobject_put() will decrement the +reference count and, possibly, free the object. Note that kobject_init() +sets the reference count to one, so the code which sets up the kobject will +need to do a kobject_put() eventually to release that reference. -void kset_init(struct kset * k); -int kset_add(struct kset * k); -int kset_register(struct kset * k); -void kset_unregister(struct kset * k); +Because kobjects are dynamic, they must not be declared statically or on +the stack, but instead, always allocated dynamically. Future versions of +the kernel will contain a run-time check for kobjects that are created +statically and will warn the developer of this improper usage. -struct kset * kset_get(struct kset * k); -void kset_put(struct kset * k); +If all that you want to use a kobject for is to provide a reference counter +for your structure, please use the struct kref instead; a kobject would be +overkill. For more information on how to use struct kref, please see the +file Documentation/kref.txt in the Linux kernel source tree. -struct kobject * kset_find_obj(struct kset *, char *); +Creating "simple" kobjects -The type that the kobjects are embedded in is described by the ktype -pointer. +Sometimes all that a developer wants is a way to create a simple directory +in the sysfs hierarchy, and not have to mess with the whole complication of +ksets, show and store functions, and other details. This is the one +exception where a single kobject should be created. To create such an +entry, use the function: -A kset contains a kobject itself, meaning that it may be registered in -the kobject hierarchy and exported via sysfs. More importantly, the -kset may be embedded in a larger data type, and may be part of another -kset (of that object type). + struct kobject *kobject_create_and_add(char *name, struct kobject *parent); -For example, a block device is an object (struct gendisk) that is -contained in a set of block devices. It may also contain a set of -partitions (struct hd_struct) that have been found on the device. The -following code snippet illustrates how to express this properly. +This function will create a kobject and place it in sysfs in the location +underneath the specified parent kobject. To create simple attributes +associated with this kobject, use: - struct gendisk * disk; - ... - disk->kset.kobj.kset = &block_kset; - disk->kset.ktype = &partition_ktype; - kset_register(&disk->kset); + int sysfs_create_file(struct kobject *kobj, struct attribute *attr); +or + int sysfs_create_group(struct kobject *kobj, struct attribute_group *grp); -- The kset that the disk's embedded object belongs to is the - block_kset, and is pointed to by disk->kset.kobj.kset. +Both types of attributes used here, with a kobject that has been created +with the kobject_create_and_add(), can be of type kobj_attribute, so no +special custom attribute is needed to be created. -- The type of objects on the disk's _subordinate_ list are partitions, - and is set in disk->kset.ktype. +See the example module, samples/kobject/kobject-example.c for an +implementation of a simple kobject and attributes. -- The kset is then registered, which handles initializing and adding - the embedded kobject to the hierarchy. -2.2 kset Programming Interface +ktypes and release methods -All kset functions, except kset_find_obj(), eventually forward the -calls to their embedded kobjects after performing kset-specific -operations. ksets offer a similar programming model to kobjects: they -may be used after they are initialized, without registering them in -the hierarchy. +One important thing still missing from the discussion is what happens to a +kobject when its reference count reaches zero. The code which created the +kobject generally does not know when that will happen; if it did, there +would be little point in using a kobject in the first place. Even +predictable object lifecycles become more complicated when sysfs is brought +in as other portions of the kernel can get a reference on any kobject that +is registered in the system. -kset_find_obj() may be used to locate a kobject with a particular -name. The kobject, if found, is returned. +The end result is that a structure protected by a kobject cannot be freed +before its reference count goes to zero. The reference count is not under +the direct control of the code which created the kobject. So that code must +be notified asynchronously whenever the last reference to one of its +kobjects goes away. -There are also some helper functions which names point to the formerly -existing "struct subsystem", whose functions have been taken over by -ksets. +Once you registered your kobject via kobject_add(), you must never use +kfree() to free it directly. The only safe way is to use kobject_put(). It +is good practice to always use kobject_put() after kobject_init() to avoid +errors creeping in. +This notification is done through a kobject's release() method. Usually +such a method has a form like: -decl_subsys(name,type,uevent_ops) + void my_object_release(struct kobject *kobj) + { + struct my_object *mine = container_of(kobj, struct my_object, kobj); -Declares a kset named '_subsys' of type with -uevent_ops . For example, + /* Perform any additional cleanup on this object, then... */ + kfree(mine); + } -decl_subsys(devices, &ktype_device, &device_uevent_ops); +One important point cannot be overstated: every kobject must have a +release() method, and the kobject must persist (in a consistent state) +until that method is called. If these constraints are not met, the code is +flawed. Note that the kernel will warn you if you forget to provide a +release() method. Do not try to get rid of this warning by providing an +"empty" release function; you will be mocked mercilessly by the kobject +maintainer if you attempt this. -is equivalent to doing: +Note, the name of the kobject is available in the release function, but it +must NOT be changed within this callback. Otherwise there will be a memory +leak in the kobject core, which makes people unhappy. -struct kset devices_subsys = { - .ktype = &ktype_devices, - .uevent_ops = &device_uevent_ops, -}; -kobject_set_name(&devices_subsys, name); +Interestingly, the release() method is not stored in the kobject itself; +instead, it is associated with the ktype. So let us introduce struct +kobj_type: + + struct kobj_type { + void (*release)(struct kobject *); + struct sysfs_ops *sysfs_ops; + struct attribute **default_attrs; + }; -The objects that are registered with a subsystem that use the -subsystem's default list must have their kset ptr set properly. These -objects may have embedded kobjects or ksets. The -following helper makes setting the kset easier: +This structure is used to describe a particular type of kobject (or, more +correctly, of containing object). Every kobject needs to have an associated +kobj_type structure; a pointer to that structure must be specified when you +call kobject_init() or kobject_init_and_add(). +The release field in struct kobj_type is, of course, a pointer to the +release() method for this type of kobject. The other two fields (sysfs_ops +and default_attrs) control how objects of this type are represented in +sysfs; they are beyond the scope of this document. -kobj_set_kset_s(obj,subsys) +The default_attrs pointer is a list of default attributes that will be +automatically created for any kobject that is registered with this ktype. -- Assumes that obj->kobj exists, and is a struct kobject. -- Sets the kset of that kobject to the kset . -int subsystem_register(struct kset *s); -void subsystem_unregister(struct kset *s); +ksets -These are just wrappers around the respective kset_* functions. +A kset is merely a collection of kobjects that want to be associated with +each other. There is no restriction that they be of the same ktype, but be +very careful if they are not. -2.3 sysfs +A kset serves these functions: -ksets are represented in sysfs when their embedded kobjects are -registered. They follow the same rules of parenting, with one -exception. If a kset does not have a parent, nor is its embedded -kobject part of another kset, the kset's parent becomes its dominant -subsystem. + - It serves as a bag containing a group of objects. A kset can be used by + the kernel to track "all block devices" or "all PCI device drivers." -If the kset does not have a parent, its directory is created at the -sysfs root. This should only happen when the kset registered is -embedded in a subsystem itself. + - A kset is also a subdirectory in sysfs, where the associated kobjects + with the kset can show up. Every kset contains a kobject which can be + set up to be the parent of other kobjects; the top-level directories of + the sysfs hierarchy are constructed in this way. + - Ksets can support the "hotplugging" of kobjects and influence how + uevent events are reported to user space. -3. struct ktype +In object-oriented terms, "kset" is the top-level container class; ksets +contain their own kobject, but that kobject is managed by the kset code and +should not be manipulated by any other user. -3.1. Description +A kset keeps its children in a standard kernel linked list. Kobjects point +back to their containing kset via their kset field. In almost all cases, +the kobjects belonging to a ket have that kset (or, strictly, its embedded +kobject) in their parent. -struct kobj_type { - void (*release)(struct kobject *); - struct sysfs_ops * sysfs_ops; - struct attribute ** default_attrs; +As a kset contains a kobject within it, it should always be dynamically +created and never declared statically or on the stack. To create a new +kset use: + struct kset *kset_create_and_add(const char *name, + struct kset_uevent_ops *u, + struct kobject *parent); + +When you are finished with the kset, call: + void kset_unregister(struct kset *kset); +to destroy it. + +An example of using a kset can be seen in the +samples/kobject/kset-example.c file in the kernel tree. + +If a kset wishes to control the uevent operations of the kobjects +associated with it, it can use the struct kset_uevent_ops to handle it: + +struct kset_uevent_ops { + int (*filter)(struct kset *kset, struct kobject *kobj); + const char *(*name)(struct kset *kset, struct kobject *kobj); + int (*uevent)(struct kset *kset, struct kobject *kobj, + struct kobj_uevent_env *env); }; -Object types require specific functions for converting between the -generic object and the more complex type. struct kobj_type provides -the object-specific fields, which include: +The filter function allows a kset to prevent a uevent from being emitted to +userspace for a specific kobject. If the function returns 0, the uevent +will not be emitted. + +The name function will be called to override the default name of the kset +that the uevent sends to userspace. By default, the name will be the same +as the kset itself, but this function, if present, can override that name. + +The uevent function will be called when the uevent is about to be sent to +userspace to allow more environment variables to be added to the uevent. + +One might ask how, exactly, a kobject is added to a kset, given that no +functions which perform that function have been presented. The answer is +that this task is handled by kobject_add(). When a kobject is passed to +kobject_add(), its kset member should point to the kset to which the +kobject will belong. kobject_add() will handle the rest. + +If the kobject belonging to a kset has no parent kobject set, it will be +added to the kset's directory. Not all members of a kset do necessarily +live in the kset directory. If an explicit parent kobject is assigned +before the kobject is added, the kobject is registered with the kset, but +added below the parent kobject. + + +Kobject removal -- release: Called when the kobject's reference count reaches 0. This - should convert the object to the more complex type and free it. +After a kobject has been registered with the kobject core successfully, it +must be cleaned up when the code is finished with it. To do that, call +kobject_put(). By doing this, the kobject core will automatically clean up +all of the memory allocated by this kobject. If a KOBJ_ADD uevent has been +sent for the object, a corresponding KOBJ_REMOVE uevent will be sent, and +any other sysfs housekeeping will be handled for the caller properly. -- sysfs_ops: Provides conversion functions for sysfs access. Please - see the sysfs documentation for more information. +If you need to do a two-stage delete of the kobject (say you are not +allowed to sleep when you need to destroy the object), then call +kobject_del() which will unregister the kobject from sysfs. This makes the +kobject "invisible", but it is not cleaned up, and the reference count of +the object is still the same. At a later time call kobject_put() to finish +the cleanup of the memory associated with the kobject. -- default_attrs: Default attributes to be exported via sysfs when the - object is registered.Note that the last attribute has to be - initialized to NULL ! You can find a complete implementation - in block/genhd.c +kobject_del() can be used to drop the reference to the parent object, if +circular references are constructed. It is valid in some cases, that a +parent objects references a child. Circular references _must_ be broken +with an explicit call to kobject_del(), so that a release functions will be +called, and the objects in the former circle release each other. -Instances of struct kobj_type are not registered; only referenced by -the kset.

Overview / What is Socket CAN +-------------------------------- + +The socketcan package is an implementation of CAN protocols +(Controller Area Network) for Linux. CAN is a networking technology +which has widespread use in automation, embedded devices, and +automotive fields. While there have been other CAN implementations +for Linux based on character devices, Socket CAN uses the Berkeley +socket API, the Linux network stack and implements the CAN device +drivers as network interfaces. The CAN socket API has been designed +as similar as possible to the TCP/IP protocols to allow programmers, +familiar with network programming, to easily learn how to use CAN +sockets. + +2. Motivation / Why using the socket API +---------------------------------------- + +There have been CAN implementations for Linux before Socket CAN so the +question arises, why we have started another project. Most existing +implementations come as a device driver for some CAN hardware, they +are based on character devices and provide comparatively little +functionality. Usually, there is only a hardware-specific device +driver which provides a character device interface to send and +receive raw CAN frames, directly to/from the controller hardware. +Queueing of frames and higher-level transport protocols like ISO-TP +have to be implemented in user space applications. Also, most +character-device implementations support only one single process to +open the device at a time, similar to a serial interface. Exchanging +the CAN controller requires employment of another device driver and +often the need for adaption of large parts of the application to the +new driver's API. + +Socket CAN was designed to overcome all of these limitations. A new +protocol family has been implemented which provides a socket interface +to user space applications and which builds upon the Linux network +layer, so to use all of the provided queueing functionality. A device +driver for CAN controller hardware registers itself with the Linux +network layer as a network device, so that CAN frames from the +controller can be passed up to the network layer and on to the CAN +protocol family module and also vice-versa. Also, the protocol family +module provides an API for transport protocol modules to register, so +that any number of transport protocols can be loaded or unloaded +dynamically. In fact, the can core module alone does not provide any +protocol and cannot be used without loading at least one additional +protocol module. Multiple sockets can be opened at the same time, +on different or the same protocol module and they can listen/send +frames on different or the same CAN IDs. Several sockets listening on +the same interface for frames with the same CAN ID are all passed the +same received matching CAN frames. An application wishing to +communicate using a specific transport protocol, e.g. ISO-TP, just +selects that protocol when opening the socket, and then can read and +write application data byte streams, without having to deal with +CAN-IDs, frames, etc. + +Similar functionality visible from user-space could be provided by a +character device, too, but this would lead to a technically inelegant +solution for a couple of reasons: + +* Intricate usage. Instead of passing a protocol argument to + socket(2) and using bind(2) to select a CAN interface and CAN ID, an + application would have to do all these operations using ioctl(2)s. + +* Code duplication. A character device cannot make use of the Linux + network queueing code, so all that code would have to be duplicated + for CAN networking. + +* Abstraction. In most existing character-device implementations, the + hardware-specific device driver for a CAN controller directly + provides the character device for the application to work with. + This is at least very unusual in Unix systems for both, char and + block devices. For example you don't have a character device for a + certain UART of a serial interface, a certain sound chip in your + computer, a SCSI or IDE controller providing access to your hard + disk or tape streamer device. Instead, you have abstraction layers + which provide a unified character or block device interface to the + application on the one hand, and a interface for hardware-specific + device drivers on the other hand. These abstractions are provided + by subsystems like the tty layer, the audio subsystem or the SCSI + and IDE subsystems for the devices mentioned above. + + The easiest way to implement a CAN device driver is as a character + device without such a (complete) abstraction layer, as is done by most + existing drivers. The right way, however, would be to add such a + layer with all the functionality like registering for certain CAN + IDs, supporting several open file descriptors and (de)multiplexing + CAN frames between them, (sophisticated) queueing of CAN frames, and + providing an API for device drivers to register with. However, then + it would be no more difficult, or may be even easier, to use the + networking framework provided by the Linux kernel, and this is what + Socket CAN does. + + The use of the networking framework of the Linux kernel is just the + natural and most appropriate way to implement CAN for Linux. + +3. Socket CAN concept +--------------------- + + As described in chapter 2 it is the main goal of Socket CAN to + provide a socket interface to user space applications which builds + upon the Linux network layer. In contrast to the commonly known + TCP/IP and ethernet networking, the CAN bus is a broadcast-only(!) + medium that has no MAC-layer addressing like ethernet. The CAN-identifier + (can_id) is used for arbitration on the CAN-bus. Therefore the CAN-IDs + have to be chosen uniquely on the bus. When designing a CAN-ECU + network the CAN-IDs are mapped to be sent by a specific ECU. + For this reason a CAN-ID can be treated best as a kind of source address. + + 3.1 receive lists + + The network transparent access of multiple applications leads to the + problem that different applications may be interested in the same + CAN-IDs from the same CAN network interface. The Socket CAN core + module - which implements the protocol family CAN - provides several + high efficient receive lists for this reason. If e.g. a user space + application opens a CAN RAW socket, the raw protocol module itself + requests the (range of) CAN-IDs from the Socket CAN core that are + requested by the user. The subscription and unsubscription of + CAN-IDs can be done for specific CAN interfaces or for all(!) known + CAN interfaces with the can_rx_(un)register() functions provided to + CAN protocol modules by the SocketCAN core (see chapter 5). + To optimize the CPU usage at runtime the receive lists are split up + into several specific lists per device that match the requested + filter complexity for a given use-case. + + 3.2 local loopback of sent frames + + As known from other networking concepts the data exchanging + applications may run on the same or different nodes without any + change (except for the according addressing information): + + ___ ___ ___ _______ ___ + | _ | | _ | | _ | | _ _ | | _ | + ||A|| ||B|| ||C|| ||A| |B|| ||C|| + |___| |___| |___| |_______| |___| + | | | | | + -----------------(1)- CAN bus -(2)--------------- + + To ensure that application A receives the same information in the + example (2) as it would receive in example (1) there is need for + some kind of local loopback of the sent CAN frames on the appropriate + node. + + The Linux network devices (by default) just can handle the + transmission and reception of media dependent frames. Due to the + arbritration on the CAN bus the transmission of a low prio CAN-ID + may be delayed by the reception of a high prio CAN frame. To + reflect the correct* traffic on the node the loopback of the sent + data has to be performed right after a successful transmission. If + the CAN network interface is not capable of performing the loopback for + some reason the SocketCAN core can do this task as a fallback solution. + See chapter 6.2 for details (recommended). + + The loopback functionality is enabled by default to reflect standard + networking behaviour for CAN applications. Due to some requests from + the RT-SocketCAN group the loopback optionally may be disabled for each + separate socket. See sockopts from the CAN RAW sockets in chapter 4.1. + + * = you really like to have this when you're running analyser tools + like 'candump' or 'cansniffer' on the (same) node. + + 3.3 network security issues (capabilities) + + The Controller Area Network is a local field bus transmitting only + broadcast messages without any routing and security concepts. + In the majority of cases the user application has to deal with + raw CAN frames. Therefore it might be reasonable NOT to restrict + the CAN access only to the user root, as known from other networks. + Since the currently implemented CAN_RAW and CAN_BCM sockets can only + send and receive frames to/from CAN interfaces it does not affect + security of others networks to allow all users to access the CAN. + To enable non-root users to access CAN_RAW and CAN_BCM protocol + sockets the Kconfig options CAN_RAW_USER and/or CAN_BCM_USER may be + selected at kernel compile time. + + 3.4 network problem notifications + + The use of the CAN bus may lead to several problems on the physical + and media access control layer. Detecting and logging of these lower + layer problems is a vital requirement for CAN users to identify + hardware issues on the physical transceiver layer as well as + arbitration problems and error frames caused by the different + ECUs. The occurrence of detected errors are important for diagnosis + and have to be logged together with the exact timestamp. For this + reason the CAN interface driver can generate so called Error Frames + that can optionally be passed to the user application in the same + way as other CAN frames. Whenever an error on the physical layer + or the MAC layer is detected (e.g. by the CAN controller) the driver + creates an appropriate error frame. Error frames can be requested by + the user application using the common CAN filter mechanisms. Inside + this filter definition the (interested) type of errors may be + selected. The reception of error frames is disabled by default. + +4. How to use Socket CAN +------------------------ + + Like TCP/IP, you first need to open a socket for communicating over a + CAN network. Since Socket CAN implements a new protocol family, you + need to pass PF_CAN as the first argument to the socket(2) system + call. Currently, there are two CAN protocols to choose from, the raw + socket protocol and the broadcast manager (BCM). So to open a socket, + you would write + + s = socket(PF_CAN, SOCK_RAW, CAN_RAW); + + and + + s = socket(PF_CAN, SOCK_DGRAM, CAN_BCM); + + respectively. After the successful creation of the socket, you would + normally use the bind(2) system call to bind the socket to a CAN + interface (which is different from TCP/IP due to different addressing + - see chapter 3). After binding (CAN_RAW) or connecting (CAN_BCM) + the socket, you can read(2) and write(2) from/to the socket or use + send(2), sendto(2), sendmsg(2) and the recv* counterpart operations + on the socket as usual. There are also CAN specific socket options + described below. + + The basic CAN frame structure and the sockaddr structure are defined + in include/linux/can.h: + + struct can_frame { + canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */ + __u8 can_dlc; /* data length code: 0 .. 8 */ + __u8 data[8] __attribute__((aligned(8))); + }; + + The alignment of the (linear) payload data[] to a 64bit boundary + allows the user to define own structs and unions to easily access the + CAN payload. There is no given byteorder on the CAN bus by + default. A read(2) system call on a CAN_RAW socket transfers a + struct can_frame to the user space. + + The sockaddr_can structure has an interface index like the + PF_PACKET socket, that also binds to a specific interface: + + struct sockaddr_can { + sa_family_t can_family; + int can_ifindex; + union { + struct { canid_t rx_id, tx_id; } tp16; + struct { canid_t rx_id, tx_id; } tp20; + struct { canid_t rx_id, tx_id; } mcnet; + struct { canid_t rx_id, tx_id; } isotp; + } can_addr; + }; + + To determine the interface index an appropriate ioctl() has to + be used (example for CAN_RAW sockets without error checking): + + int s; + struct sockaddr_can addr; + struct ifreq ifr; + + s = socket(PF_CAN, SOCK_RAW, CAN_RAW); + + strcpy(ifr.ifr_name, "can0" ); + ioctl(s, SIOCGIFINDEX, &ifr); + + addr.can_family = AF_CAN; + addr.can_ifindex = ifr.ifr_ifindex; + + bind(s, (struct sockaddr *)&addr, sizeof(addr)); + + (..) + + To bind a socket to all(!) CAN interfaces the interface index must + be 0 (zero). In this case the socket receives CAN frames from every + enabled CAN interface. To determine the originating CAN interface + the system call recvfrom(2) may be used instead of read(2). To send + on a socket that is bound to 'any' interface sendto(2) is needed to + specify the outgoing interface. + + Reading CAN frames from a bound CAN_RAW socket (see above) consists + of reading a struct can_frame: + + struct can_frame frame; + + nbytes = read(s, &frame, sizeof(struct can_frame)); + + if (nbytes < 0) { + perror("can raw socket read"); + return 1; + } + + /* paraniod check ... */ + if (nbytes < sizeof(struct can_frame)) { + fprintf(stderr, "read: incomplete CAN frame\n"); + return 1; + } + + /* do something with the received CAN frame */ + + Writing CAN frames can be done similarly, with the write(2) system call: + + nbytes = write(s, &frame, sizeof(struct can_frame)); + + When the CAN interface is bound to 'any' existing CAN interface + (addr.can_ifindex = 0) it is recommended to use recvfrom(2) if the + information about the originating CAN interface is needed: + + struct sockaddr_can addr; + struct ifreq ifr; + socklen_t len = sizeof(addr); + struct can_frame frame; + + nbytes = recvfrom(s, &frame, sizeof(struct can_frame), + 0, (struct sockaddr*)&addr, &len); + + /* get interface name of the received CAN frame */ + ifr.ifr_ifindex = addr.can_ifindex; + ioctl(s, SIOCGIFNAME, &ifr); + printf("Received a CAN frame from interface %s", ifr.ifr_name); + + To write CAN frames on sockets bound to 'any' CAN interface the + outgoing interface has to be defined certainly. + + strcpy(ifr.ifr_name, "can0"); + ioctl(s, SIOCGIFINDEX, &ifr); + addr.can_ifindex = ifr.ifr_ifindex; + addr.can_family = AF_CAN; + + nbytes = sendto(s, &frame, sizeof(struct can_frame), + 0, (struct sockaddr*)&addr, sizeof(addr)); + + 4.1 RAW protocol sockets with can_filters (SOCK_RAW) + + Using CAN_RAW sockets is extensively comparable to the commonly + known access to CAN character devices. To meet the new possibilities + provided by the multi user SocketCAN approach, some reasonable + defaults are set at RAW socket binding time: + + - The filters are set to exactly one filter receiving everything + - The socket only receives valid data frames (=> no error frames) + - The loopback of sent CAN frames is enabled (see chapter 3.2) + - The socket does not receive its own sent frames (in loopback mode) + + These default settings may be changed before or after binding the socket. + To use the referenced definitions of the socket options for CAN_RAW + sockets, include . + + 4.1.1 RAW socket option CAN_RAW_FILTER + + The reception of CAN frames using CAN_RAW sockets can be controlled + by defining 0 .. n filters with the CAN_RAW_FILTER socket option. + + The CAN filter structure is defined in include/linux/can.h: + + struct can_filter { + canid_t can_id; + canid_t can_mask; + }; + + A filter matches, when + + & mask == can_id & mask + + which is analogous to known CAN controllers hardware filter semantics. + The filter can be inverted in this semantic, when the CAN_INV_FILTER + bit is set in can_id element of the can_filter structure. In + contrast to CAN controller hardware filters the user may set 0 .. n + receive filters for each open socket separately: + + struct can_filter rfilter[2]; + + rfilter[0].can_id = 0x123; + rfilter[0].can_mask = CAN_SFF_MASK; + rfilter[1].can_id = 0x200; + rfilter[1].can_mask = 0x700; + + setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, &rfilter, sizeof(rfilter)); + + To disable the reception of CAN frames on the selected CAN_RAW socket: + + setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, NULL, 0); + + To set the filters to zero filters is quite obsolete as not read + data causes the raw socket to discard the received CAN frames. But + having this 'send only' use-case we may remove the receive list in the + Kernel to save a little (really a very little!) CPU usage. + + 4.1.2 RAW socket option CAN_RAW_ERR_FILTER + + As described in chapter 3.4 the CAN interface driver can generate so + called Error Frames that can optionally be passed to the user + application in the same way as other CAN frames. The possible + errors are divided into different error classes that may be filtered + using the appropriate error mask. To register for every possible + error condition CAN_ERR_MASK can be used as value for the error mask. + The values for the error mask are defined in linux/can/error.h . + + can_err_mask_t err_mask = ( CAN_ERR_TX_TIMEOUT | CAN_ERR_BUSOFF ); + + setsockopt(s, SOL_CAN_RAW, CAN_RAW_ERR_FILTER, + &err_mask, sizeof(err_mask)); + + 4.1.3 RAW socket option CAN_RAW_LOOPBACK + + To meet multi user needs the local loopback is enabled by default + (see chapter 3.2 for details). But in some embedded use-cases + (e.g. when only one application uses the CAN bus) this loopback + functionality can be disabled (separately for each socket): + + int loopback = 0; /* 0 = disabled, 1 = enabled (default) */ + + setsockopt(s, SOL_CAN_RAW, CAN_RAW_LOOPBACK, &loopback, sizeof(loopback)); + + 4.1.4 RAW socket option CAN_RAW_RECV_OWN_MSGS + + When the local loopback is enabled, all the sent CAN frames are + looped back to the open CAN sockets that registered for the CAN + frames' CAN-ID on this given interface to meet the multi user + needs. The reception of the CAN frames on the same socket that was + sending the CAN frame is assumed to be unwanted and therefore + disabled by default. This default behaviour may be changed on + demand: + + int recv_own_msgs = 1; /* 0 = disabled (default), 1 = enabled */ + + setsockopt(s, SOL_CAN_RAW, CAN_RAW_RECV_OWN_MSGS, + &recv_own_msgs, sizeof(recv_own_msgs)); + + 4.2 Broadcast Manager protocol sockets (SOCK_DGRAM) + 4.3 connected transport protocols (SOCK_SEQPACKET) + 4.4 unconnected transport protocols (SOCK_DGRAM) + + +5. Socket CAN core module +------------------------- + + The Socket CAN core module implements the protocol family + PF_CAN. CAN protocol modules are loaded by the core module at + runtime. The core module provides an interface for CAN protocol + modules to subscribe needed CAN IDs (see chapter 3.1). + + 5.1 can.ko module params + + - stats_timer: To calculate the Socket CAN core statistics + (e.g. current/maximum frames per second) this 1 second timer is + invoked at can.ko module start time by default.

CAN network drivers +---------------------- + + Writing a CAN network device driver is much easier than writing a + CAN character device driver. Similar to other known network device + drivers you mainly have to deal with: + + - TX: Put the CAN frame from the socket buffer to the CAN controller. + - RX: Put the CAN frame from the CAN controller to the socket buffer. + + See e.g. at Documentation/networking/netdevices.txt . The differences + for writing CAN network device driver are described below: + + 6.1 general settings + + dev->type = ARPHRD_CAN; /* the netdevice hardware type */ + dev->flags = IFF_NOARP; /* CAN has no arp */ + + dev->mtu = sizeof(struct can_frame); + + The struct can_frame is the payload of each socket buffer in the + protocol family PF_CAN. + + 6.2 local loopback of sent frames + + As described in chapter 3.2 the CAN network device driver should + support a local loopback functionality similar to the local echo + e.g. of tty devices. In this case the driver flag IFF_ECHO has to be + set to prevent the PF_CAN core from locally echoing sent frames + (aka loopback) as fallback solution: + + dev->flags = (IFF_NOARP | IFF_ECHO); + + 6.3 CAN controller hardware filters + + To reduce the interrupt load on deep embedded systems some CAN + controllers support the filtering of CAN IDs or ranges of CAN IDs. + These hardware filter capabilities vary from controller to + controller and have to be identified as not feasible in a multi-user + networking approach. The use of the very controller specific + hardware filters could make sense in a very dedicated use-case, as a + filter on driver level would affect all users in the multi-user + system. The high efficient filter sets inside the PF_CAN core allow + to set different multiple filters for each socket separately. + Therefore the use of hardware filters goes to the category 'handmade + tuning on deep embedded systems'.

+ break; + case 'M': + case 'm': + mem <<= 20; + break; + case 'K': + case 'k': + mem <<= 10; + /* fall through */ + default: + break; + } + + +不要把多个语句放在一行里，除非你有什么东西要隐藏： + + if (condition) do_this; + do_something_everytime; + +也不要在一行里放多个赋值语句。内核代码风格超级简单。就是避免可能导致别人误读的表 +达式。 + +除了注释、文档和Kconfig之外，不要使用空格来缩进，前面的例子是例外，是有意为之。 + +选用一个好的编辑器，不要在行尾留空格。 + + + 第二章：把长的行和字符串打散 + +代码风格的意义就在于使用平常使用的工具来维持代码的可读性和可维护性。 + +每一行的长度的限制是80列，我们强烈建议您遵守这个惯例。 + +长于80列的语句要打散成有意义的片段。每个片段要明显短于原来的语句，而且放置的位置 +也明显的靠右。同样的规则也适用于有很长参数列表的函数头。长字符串也要打散成较短的 +字符串。唯一的例外是超过80列可以大幅度提高可读性并且不会隐藏信息的情况。 + +void fun(int a, int b, int c) +{ + if (condition) + printk(KERN_WARNING "Warning this is a long printk with " + "3 parameters a: %u b: %u " + "c: %u \n", a, b, c); + else + next_statement; +} + + 第三章：大括号和空格的放置 + +C语言风格中另外一个常见问题是大括号的放置。和缩进大小不同，选择或弃用某种放置策 +略并没有多少技术上的原因，不过首选的方式，就像Kernighan和Ritchie展示给我们的，是 +把起始大括号放在行尾，而把结束大括号放在行首，所以： + + if (x is true) { + we do y + } + +这适用于所有的非函数语句块（if、switch、for、while、do）。比如： + + switch (action) { + case KOBJ_ADD: + return "add"; + case KOBJ_REMOVE: + return "remove"; + case KOBJ_CHANGE: + return "change"; + default: + return NULL; + } + +不过，有一个例外，那就是函数：函数的起始大括号放置于下一行的开头，所以： + + int function(int x) + { + body of function + } + +全世界的异端可能会抱怨这个不一致性是……呃……不一致的，不过所有思维健全的人都知道（ +a）K&R是_正确的_，并且（b）K&R是正确的。此外，不管怎样函数都是特殊的（在C语言中 +，函数是不能嵌套的）。 + +注意结束大括号独自占据一行，除非它后面跟着同一个语句的剩余部分，也就是do语句中的 +“while”或者if语句中的“else”，像这样： + + do { + body of do-loop + } while (condition); + +和 + + if (x == y) { + .. + } else if (x > y) { + ... + } else { + .... + } + +理由：K&R。 + +也请注意这种大括号的放置方式也能使空（或者差不多空的）行的数量最小化，同时不失可 +读性。因此，由于你的屏幕上的新行是不可再生资源（想想25行的终端屏幕），你将会有更 +多的空行来放置注释。 + +当只有一个单独的语句的时候，不用加不必要的大括号。 + +if (condition) + action(); + +这点不适用于本身为某个条件语句的一个分支的单独语句。这时需要在两个分支里都使用大 +括号。 + +if (condition) { + do_this(); + do_that(); +} else { + otherwise(); +} + + 3.1：空格 + +Linux内核的空格使用方式（主要）取决于它是用于函数还是关键字。（大多数）关键字后 +要加一个空格。值得注意的例外是sizeof、typeof、alignof和__attribute__，这些关键字 +某些程度上看起来更像函数（它们在Linux里也常常伴随小括号而使用，尽管在C语言里这样 +的小括号不是必需的，就像“struct fileinfo info”声明过后的“sizeof info”）。 + +所以在这些关键字之后放一个空格： + if, switch, case, for, do, while +但是不要在sizeof、typeof、alignof或者__attribute__这些关键字之后放空格。例如， + s = sizeof(struct file); + +不要在小括号里的表达式两侧加空格。这是一个反例： + + s = sizeof( struct file ); + +当声明指针类型或者返回指针类型的函数时，“*”的首选使用方式是使之靠近变量名或者函 +数名，而不是靠近类型名。例子： + + char *linux_banner; + unsigned long long memparse(char *ptr, char **retptr); + char *match_strdup(substring_t *s); + +在大多数二元和三元操作符两侧使用一个空格，例如下面所有这些操作符： + + = + - < > * / % | & ^ <= >= == != ? : + +但是一元操作符后不要加空格： + & * + - ~ ! sizeof typeof alignof __attribute__ defined + +后缀自加和自减一元操作符前不加空格： + ++ -- + +前缀自加和自减一元操作符后不加空格： + ++ -- + +“.”和“->”结构体成员操作符前后不加空格。 + +不要在行尾留空白。有些可以自动缩进的编辑器会在新行的行首加入适量的空白，然后你 +就可以直接在那一行输入代码。不过假如你最后没有在那一行输入代码，有些编辑器就不 +会移除已经加入的空白，就像你故意留下一个只有空白的行。包含行尾空白的行就这样产 +生了。 + +当git发现补丁包含了行尾空白的时候会警告你，并且可以应你的要求去掉行尾空白；不过 +如果你是正在打一系列补丁，这样做会导致后面的补丁失败，因为你改变了补丁的上下文。 + + + 第四章：命名 + +C是一个简朴的语言，你的命名也应该这样。和Modula-2和Pascal程序员不同，C程序员不使 +用类似ThisVariableIsATemporaryCounter这样华丽的名字。C程序员会称那个变量为“tmp” +，这样写起来会更容易，而且至少不会令其难于理解。 + +不过，虽然混用大小写的名字是不提倡使用的，但是全局变量还是需要一个具描述性的名字 +。称一个全局函数为“foo”是一个难以饶恕的错误。 + +全局变量（只有当你真正需要它们的时候再用它）需要有一个具描述性的名字，就像全局函 +数。如果你有一个可以计算活动用户数量的函数，你应该叫它“count_active_users()”或者 +类似的名字，你不应该叫它“cntuser()”。 + +在函数名中包含函数类型（所谓的匈牙利命名法）是脑子出了问题——编译器知道那些类型而 +且能够检查那些类型，这样做只能把程序员弄糊涂了。难怪微软总是制造出有问题的程序。 + +本地变量名应该简短，而且能够表达相关的含义。如果你有一些随机的整数型的循环计数器 +，它应该被称为“i”。叫它“loop_counter”并无益处，如果它没有被误解的可能的话。类似 +的，“tmp”可以用来称呼任意类型的临时变量。 + +如果你怕混淆了你的本地变量名，你就遇到另一个问题了，叫做函数增长荷尔蒙失衡综合症 +。请看第六章（函数）。 + + + 第五章：Typedef + +不要使用类似“vps_t”之类的东西。 + +对结构体和指针使用typedef是一个错误。当你在代码里看到： + + vps_t a; + +这代表什么意思呢？ + +相反，如果是这样 + + struct virtual_container *a; + +你就知道“a”是什么了。 + +很多人认为typedef“能提高可读性”。实际不是这样的。它们只在下列情况下有用： + + (a) 完全不透明的对象（这种情况下要主动使用typedef来隐藏这个对象实际上是什么）。 + + 例如：“pte_t”等不透明对象，你只能用合适的访问函数来访问它们。 + + 注意！不透明性和“访问函数”本身是不好的。我们使用pte_t等类型的原因在于真的是 + 完全没有任何共用的可访问信息。 + + (b) 清楚的整数类型，如此，这层抽象就可以帮助消除到底是“int”还是“long”的混淆。 + + u8/u16/u32是完全没有问题的typedef，不过它们更符合类别(d)而不是这里。 + + 再次注意！要这样做，必须事出有因。如果某个变量是“unsigned long“，那么没有必要 + + typedef unsigned long myflags_t; + + 不过如果有一个明确的原因，比如它在某种情况下可能会是一个“unsigned int”而在 + 其他情况下可能为“unsigned long”，那么就不要犹豫，请务必使用typedef。 + + (c) 当你使用sparse按字面的创建一个新类型来做类型检查的时候。 + + (d) 和标准C99类型相同的类型，在某些例外的情况下。 + + 虽然让眼睛和脑筋来适应新的标准类型比如“uint32_t”不需要花很多时间，可是有些 + 人仍然拒绝使用它们。 + + 因此，Linux特有的等同于标准类型的“u8/u16/u32/u64”类型和它们的有符号类型是被 + 允许的——尽管在你自己的新代码中，它们不是强制要求要使用的。 + + 当编辑已经使用了某个类型集的已有代码时，你应该遵循那些代码中已经做出的选择。 + + (e) 可以在用户空间安全使用的类型。 + + 在某些用户空间可见的结构体里，我们不能要求C99类型而且不能用上面提到的“u32” + 类型。因此，我们在与用户空间共享的所有结构体中使用__u32和类似的类型。 + +可能还有其他的情况，不过基本的规则是永远不要使用typedef，除非你可以明确的应用上 +述某个规则中的一个。 + +总的来说，如果一个指针或者一个结构体里的元素可以合理的被直接访问到，那么它们就不 +应该是一个typedef。 + + + 第六章：函数 + +函数应该简短而漂亮，并且只完成一件事情。函数应该可以一屏或者两屏显示完（我们都知 +道ISO/ANSI屏幕大小是80x24），只做一件事情，而且把它做好。 + +一个函数的最大长度是和该函数的复杂度和缩进级数成反比的。所以，如果你有一个理论上 +很简单的只有一个很长（但是简单）的case语句的函数，而且你需要在每个case里做很多很 +小的事情，这样的函数尽管很长，但也是可以的。 + +不过，如果你有一个复杂的函数，而且你怀疑一个天分不是很高的高中一年级学生可能甚至 +搞不清楚这个函数的目的，你应该严格的遵守前面提到的长度限制。使用辅助函数，并为之 +取个具描述性的名字（如果你觉得它们的性能很重要的话，可以让编译器内联它们，这样的 +效果往往会比你写一个复杂函数的效果要好。） + +函数的另外一个衡量标准是本地变量的数量。此数量不应超过5－10个，否则你的函数就有 +问题了。重新考虑一下你的函数，把它分拆成更小的函数。人的大脑一般可以轻松的同时跟 +踪7个不同的事物，如果再增多的话，就会糊涂了。即便你聪颖过人，你也可能会记不清你2 +个星期前做过的事情。 + +在源文件里，使用空行隔开不同的函数。如果该函数需要被导出，它的EXPORT*宏应该紧贴 +在它的结束大括号之下。比如： + +int system_is_up(void) +{ + return system_state == SYSTEM_RUNNING; +} +EXPORT_SYMBOL(system_is_up); + +在函数原型中，包含函数名和它们的数据类型。虽然C语言里没有这样的要求，在Linux里这 +是提倡的做法，因为这样可以很简单的给读者提供更多的有价值的信息。 + + + 第七章：集中的函数退出途径 + +虽然被某些人声称已经过时，但是goto语句的等价物还是经常被编译器所使用，具体形式是 +无条件跳转指令。 + +当一个函数从多个位置退出并且需要做一些通用的清理工作的时候，goto的好处就显现出来 +了。 + +理由是： + +- 无条件语句容易理解和跟踪 +- 嵌套程度减小 +- 可以避免由于修改时忘记更新某个单独的退出点而导致的错误 +- 减轻了编译器的工作，无需删除冗余代码;) + +int fun(int a) +{ + int result = 0; + char *buffer = kmalloc(SIZE); + + if (buffer == NULL) + return -ENOMEM; + + if (condition1) { + while (loop1) { + ... + } + result = 1; + goto out; + } + ... +out: + kfree(buffer); + return result; +} + + 第八章：注释 + +注释是好的，不过有过度注释的危险。永远不要在注释里解释你的代码是如何运作的：更好 +的做法是让别人一看你的代码就可以明白，解释写的很差的代码是浪费时间。 + +一般的，你想要你的注释告诉别人你的代码做了什么，而不是怎么做的。也请你不要把注释 +放在一个函数体内部：如果函数复杂到你需要独立的注释其中的一部分，你很可能需要回到 +第六章看一看。你可以做一些小注释来注明或警告某些很聪明（或者槽糕）的做法，但不要 +加太多。你应该做的，是把注释放在函数的头部，告诉人们它做了什么，也可以加上它做这 +些事情的原因。 + +当注释内核API函数时，请使用kernel-doc格式。请看 +Documentation/kernel-doc-nano-HOWTO.txt和scripts/kernel-doc以获得详细信息。 + +Linux的注释风格是C89“/* ... */”风格。不要使用C99风格“// ...”注释。 + +长（多行）的首选注释风格是： + + /* + * This is the preferred style for multi-line + * comments in the Linux kernel source code. + * Please use it consistently. + * + * Description: A column of asterisks on the left side, + * with beginning and ending almost-blank lines. + */ + +注释数据也是很重要的，不管是基本类型还是衍生类型。为了方便实现这一点，每一行应只 +声明一个数据（不要使用逗号来一次声明多个数据）。这样你就有空间来为每个数据写一段 +小注释来解释它们的用途了。 + + + 第九章：你已经把事情弄糟了 + +这没什么，我们都是这样。可能你的使用了很长时间Unix的朋友已经告诉你“GNU emacs”能 +自动帮你格式化C源代码，而且你也注意到了，确实是这样，不过它所使用的默认值和我们 +想要的相去甚远（实际上，甚至比随机打的还要差——无数个猴子在GNU emacs里打字永远不 +会创造出一个好程序）（译注：请参考Infinite Monkey Theorem） + +所以你要么放弃GNU emacs，要么改变它让它使用更合理的设定。要采用后一个方案，你可 +以把下面这段粘贴到你的.emacs文件里。 + +(defun linux-c-mode () + "C mode with adjusted defaults for use with the Linux kernel." + (interactive) + (c-mode) + (c-set-style "K&R") + (setq tab-width 8) + (setq indent-tabs-mode t) + (setq c-basic-offset 8)) + +这样就定义了M-x linux-c-mode命令。当你hack一个模块的时候，如果你把字符串 +-*- linux-c -*-放在头两行的某个位置，这个模式将会被自动调用。如果你希望在你修改 +/usr/src/linux里的文件时魔术般自动打开linux-c-mode的话，你也可能需要添加 + +(setq auto-mode-alist (cons '("/usr/src/linux.*/.*\\.[ch]$" . linux-c-mode) + auto-mode-alist)) + +到你的.emacs文件里。 + +不过就算你尝试让emacs正确的格式化代码失败了，也并不意味着你失去了一切：还可以用“ +indent”。 + +不过，GNU indent也有和GNU emacs一样有问题的设定，所以你需要给它一些命令选项。不 +过，这还不算太糟糕，因为就算是GNU indent的作者也认同K&R的权威性（GNU的人并不是坏 +人，他们只是在这个问题上被严重的误导了），所以你只要给indent指定选项“-kr -i8” +（代表“K&R，8个字符缩进”），或者使用“scripts/Lindent”，这样就可以以最时髦的方式 +缩进源代码。 + +“indent”有很多选项，特别是重新格式化注释的时候，你可能需要看一下它的手册页。不过 +记住：“indent”不能修正坏的编程习惯。 + + + 第十章：Kconfig配置文件 + +对于遍布源码树的所有Kconfig*配置文件来说，它们缩进方式与C代码相比有所不同。紧挨 +在“config”定义下面的行缩进一个制表符，帮助信息则再多缩进2个空格。比如： + +config AUDIT + bool "Auditing support" + depends on NET + help + Enable auditing infrastructure that can be used with another + kernel subsystem, such as SELinux (which requires this for + logging of avc messages output). Does not do system-call + auditing without CONFIG_AUDITSYSCALL. + +仍然被认为不够稳定的功能应该被定义为依赖于“EXPERIMENTAL”： + +config SLUB + depends on EXPERIMENTAL && !ARCH_USES_SLAB_PAGE_STRUCT + bool "SLUB (Unqueued Allocator)" + ... + +而那些危险的功能（比如某些文件系统的写支持）应该在它们的提示字符串里显著的声明这 +一点： + +config ADFS_FS_RW + bool "ADFS write support (DANGEROUS)" + depends on ADFS_FS + ... + +要查看配置文件的完整文档，请看Documentation/kbuild/kconfig-language.txt。 + + + 第十一章：数据结构 + +如果一个数据结构，在创建和销毁它的单线执行环境之外可见，那么它必须要有一个引用计 +数器。内核里没有垃圾收集（并且内核之外的垃圾收集慢且效率低下），这意味着你绝对需 +要记录你对这种数据结构的使用情况。 + +引用计数意味着你能够避免上锁，并且允许多个用户并行访问这个数据结构——而不需要担心 +这个数据结构仅仅因为暂时不被使用就消失了，那些用户可能不过是沉睡了一阵或者做了一 +些其他事情而已。 + +注意上锁不能取代引用计数。上锁是为了保持数据结构的一致性，而引用计数是一个内存管 +理技巧。通常二者都需要，不要把两个搞混了。 + +很多数据结构实际上有2级引用计数，它们通常有不同“类”的用户。子类计数器统计子类用 +户的数量，每当子类计数器减至零时，全局计数器减一。 + +这种“多级引用计数”的例子可以在内存管理（“struct mm_struct”：mm_users和mm_count） +和文件系统（“struct super_block”：s_count和s_active）中找到。 + +记住：如果另一个执行线索可以找到你的数据结构，但是这个数据结构没有引用计数器，这 +里几乎肯定是一个bug。 + + + 第十二章：宏，枚举和RTL + +用于定义常量的宏的名字及枚举里的标签需要大写。 + +#define CONSTANT 0x12345 + +在定义几个相关的常量时，最好用枚举。 + +宏的名字请用大写字母，不过形如函数的宏的名字可以用小写字母。 + +一般的，如果能写成内联函数就不要写成像函数的宏。 + +含有多个语句的宏应该被包含在一个do-while代码块里： + +#define macrofun(a, b, c) \ + do { \ + if (a == 5) \ + do_this(b, c); \ + } while (0) + +使用宏的时候应避免的事情： + +1) 影响控制流程的宏： + +#define FOO(x) \ + do { \ + if (blah(x) < 0) \ + return -EBUGGERED; \ + } while(0) + +非常不好。它看起来像一个函数，不过却能导致“调用”它的函数退出；不要打乱读者大脑里 +的语法分析器。 + +2) 依赖于一个固定名字的本地变量的宏： + +#define FOO(val) bar(index, val) + +可能看起来像是个不错的东西，不过它非常容易把读代码的人搞糊涂，而且容易导致看起来 +不相关的改动带来错误。 + +3) 作为左值的带参数的宏： FOO(x) = y；如果有人把FOO变成一个内联函数的话，这种用 +法就会出错了。 + +4) 忘记了优先级：使用表达式定义常量的宏必须将表达式置于一对小括号之内。带参数的 +宏也要注意此类问题。 + +#define CONSTANT 0x4000 +#define CONSTEXP (CONSTANT | 3) + +cpp手册对宏的讲解很详细。Gcc internals手册也详细讲解了RTL（译注：register +transfer language），内核里的汇编语言经常用到它。 + + + 第十三章：打印内核消息 + +内核开发者应该是受过良好教育的。请一定注意内核信息的拼写，以给人以好的印象。不要 +用不规范的单词比如“dont”，而要用“do not”或者“don't”。保证这些信息简单、明了、无 +歧义。 + +内核信息不必以句号（译注：英文句号，即点）结束。 + +在小括号里打印数字(%d)没有任何价值，应该避免这样做。 + +里有一些驱动模型诊断宏，你应该使用它们，以确保信息对应于正确的 +设备和驱动，并且被标记了正确的消息级别。这些宏有：dev_err(), dev_warn(), +dev_info()等等。对于那些不和某个特定设备相关连的信息，定义了 +pr_debug()和pr_info()。 + +写出好的调试信息可以是一个很大的挑战；当你写出来之后，这些信息在远程除错的时候 +就会成为极大的帮助。当DEBUG符号没有被定义的时候，这些信息不应该被编译进内核里 +（也就是说，默认地，它们不应该被包含在内）。如果你使用dev_dbg()或者pr_debug()， +就能自动达到这个效果。很多子系统拥有Kconfig选项来启用-DDEBUG。还有一个相关的惯例 +是使用VERBOSE_DEBUG来添加dev_vdbg()消息到那些已经由DEBUG启用的消息之上。 + + + 第十四章：分配内存 + +内核提供了下面的一般用途的内存分配函数：kmalloc()，kzalloc()，kcalloc()和 +vmalloc()。请参考API文档以获取有关它们的详细信息。 + +传递结构体大小的首选形式是这样的： + + p = kmalloc(sizeof(*p), ...); + +另外一种传递方式中，sizeof的操作数是结构体的名字，这样会降低可读性，并且可能会引 +入bug。有可能指针变量类型被改变时，而对应的传递给内存分配函数的sizeof的结果不变。 + +强制转换一个void指针返回值是多余的。C语言本身保证了从void指针到其他任何指针类型 +的转换是没有问题的。 + + + 第十五章：内联弊病 + +有一个常见的误解是内联函数是gcc提供的可以让代码运行更快的一个选项。虽然使用内联 +函数有时候是恰当的（比如作为一种替代宏的方式，请看第十二章），不过很多情况下不是 +这样。inline关键字的过度使用会使内核变大，从而使整个系统运行速度变慢。因为大内核 +会占用更多的指令高速缓存（译注：一级缓存通常是指令缓存和数据缓存分开的）而且会导 +致pagecache的可用内存减少。想象一下，一次pagecache未命中就会导致一次磁盘寻址，将 +耗时5毫秒。5毫秒的时间内CPU能执行很多很多指令。 + +一个基本的原则是如果一个函数有3行以上，就不要把它变成内联函数。这个原则的一个例 +外是，如果你知道某个参数是一个编译时常量，而且因为这个常量你确定编译器在编译时能 +优化掉你的函数的大部分代码，那仍然可以给它加上inline关键字。kmalloc()内联函数就 +是一个很好的例子。 + +人们经常主张给static的而且只用了一次的函数加上inline，如此不会有任何损失，因为没 +有什么好权衡的。虽然从技术上说这是正确的，但是实际上这种情况下即使不加inline gcc +也可以自动使其内联。而且其他用户可能会要求移除inline，由此而来的争论会抵消inline +自身的潜在价值，得不偿失。 + + + 第十六章：函数返回值及命名 + +函数可以返回很多种不同类型的值，最常见的一种是表明函数执行成功或者失败的值。这样 +的一个值可以表示为一个错误代码整数（-Exxx＝失败，0＝成功）或者一个“成功”布尔值（ +0＝失败，非0＝成功）。 + +混合使用这两种表达方式是难于发现的bug的来源。如果C语言本身严格区分整形和布尔型变 +量，那么编译器就能够帮我们发现这些错误……不过C语言不区分。为了避免产生这种bug，请 +遵循下面的惯例： + + 如果函数的名字是一个动作或者强制性的命令，那么这个函数应该返回错误代码整 + 数。如果是一个判断，那么函数应该返回一个“成功”布尔值。 + +比如，“add work”是一个命令，所以add_work()函数在成功时返回0，在失败时返回-EBUSY。 +类似的，因为“PCI device present”是一个判断，所以pci_dev_present()函数在成功找到 +一个匹配的设备时应该返回1，如果找不到时应该返回0。 + +所有导出（译注：EXPORT）的函数都必须遵守这个惯例，所有的公共函数也都应该如此。私 +有（static）函数不需要如此，但是我们也推荐这样做。 + +返回值是实际计算结果而不是计算是否成功的标志的函数不受此惯例的限制。一般的，他们 +通过返回一些正常值范围之外的结果来表示出错。典型的例子是返回指针的函数，他们使用 +NULL或者ERR_PTR机制来报告错误。 + + + 第十七章：不要重新发明内核宏 + +头文件include/linux/kernel.h包含了一些宏，你应该使用它们，而不要自己写一些它们的 +变种。比如，如果你需要计算一个数组的长度，使用这个宏 + + #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0])) + +类似的，如果你要计算某结构体成员的大小，使用 + + #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f)) + +还有可以做严格的类型检查的min()和max()宏，如果你需要可以使用它们。你可以自己看看 +那个头文件里还定义了什么你可以拿来用的东西，如果有定义的话，你就不应在你的代码里 +自己重新定义。 + + + 第十八章：编辑器模式行和其他需要罗嗦的事情 + +有一些编辑器可以解释嵌入在源文件里的由一些特殊标记标明的配置信息。比如，emacs +能够解释被标记成这样的行： + +-*- mode: c -*- + +或者这样的： + +/* +Local Variables: +compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c" +End: +*/ + +Vim能够解释这样的标记： + +/* vim:set sw=8 noet */ + +不要在源代码中包含任何这样的内容。每个人都有他自己的编辑器配置，你的源文件不应 +该覆盖别人的配置。这包括有关缩进和模式配置的标记。人们可以使用他们自己定制的模 +式，或者使用其他可以产生正确的缩进的巧妙方法。 + + + + 附录 I：参考 + +The C Programming Language, 第二版, 作者Brian W.

charset=us-ascii; format=flowed +---- 邮件头 ---- +问题在于 “format=flowed” 会让接收端的某些邮件软件将邮件中的制表符替换 +成空格以及做一些类似的替换。这样，你发送的时候看起来没问题的补丁就被破 +坏了。 + +要修正这个问题，只需要将你的 mozilla 的 defaults/pref/mailnews.js 文件 +里的 +pref("mailnews.send_plaintext_flowed", false); // RFC 2646======= +修改成 +pref("mailnews.display.disable_format_flowed_support", true); +就可以了。 + +7) e-mail 的大小 + +给 Linus 发送补丁的时候，永远按照第6小节说的做。 + +大的改动对邮件列表不合适，对某些维护者也不合适。如果你的补丁，在不压缩 +的情况下，超过了40kB，那么你最好将补丁放在一个能通过 internet 访问的服 +务器上，然后用指向你的补丁的 URL 替代。 + +8) 指出你的内核版本 + +在标题和在补丁的描述中，指出补丁对应的内核的版本，是很重要的。 + +如果补丁不能干净的在最新版本的内核上打上，Linus 是不会接受它的。 + +9) 不要气馁，继续提交。 + +当你提交了改动以后，耐心地等待。如果 Linus 喜欢你的改动并且同意它，那么 +它将在下一个内核发布版本中出现。 + +然而，如果你的改动没有出现在下一个版本的内核中，可能有若干原因。减少那 +些原因，修正错误，重新提交更新后的改动，是你自己的工作。 + +Linus不给出任何评论就“丢弃”你的补丁是常见的事情。在系统中这样的事情很 +平常。如果他没有接受你的补丁，也许是由于以下原本： +* 你的补丁不能在最新版本的内核上干净的打上。 +* 你的补丁在 linux-kernel 邮件列表中没有得到充分的讨论。 +* 风格问题（参照第2小节） +* 邮件格式问题（重读本节） +* 你的改动有技术问题。 +* 他收到了成吨的 e-mail，而你的在混乱中丢失了。 +* 你让人为难。 + +有疑问的时候，在 linux-kernel 邮件列表上请求评论。 + +10) 在标题上加上 PATCH 的字样 + +Linus 和 linux-kernel 邮件列表的 e-mail 流量都很高，一个通常的约定是标 +题行以 [PATCH] 开头。这样可以让 Linus 和其他内核开发人员可以从 e-mail +的讨论中很轻易的将补丁分辨出来。 + +11）为你的工作签名 + +为了加强对谁做了何事的追踪，尤其是对那些透过好几层的维护者的补丁，我们 +建议在发送出去的补丁上加一个 “sign-off” 的过程。 + +"sign-off" 是在补丁的注释的最后的简单的一行文字，认证你编写了它或者其他 +人有权力将它作为开放源代码的补丁传递。规则很简单：如果你能认证如下信息 +： + 开发者来源证书 1.1 + 对于本项目的贡献，我认证如下信息： + （a）这些贡献是完全或者部分的由我创建，我有权利以文件中指出 + 的开放源代码许可证提交它；或者 + （b）这些贡献基于以前的工作，据我所知，这些以前的工作受恰当的开放 + 源代码许可证保护，而且，根据许可证，我有权提交修改后的贡献， + 无论是完全还是部分由我创造，这些贡献都使用同一个开放源代码许可证 + （除非我被允许用其它的许可证），正如文件中指出的；或者 + （c）这些贡献由认证（a），（b）或者（c）的人直接提供给我，而 + 且我没有修改它。 + （d）我理解并同意这个项目和贡献是公开的，贡献的记录（包括我 + 一起提交的个人记录，包括 sign-off ）被永久维护并且可以和这个项目 + 或者开放源代码的许可证同步地再发行。 + 那么加入这样一行： + Signed-off-by: Random J Developer + +使用你的真名（抱歉，不能使用假名或者匿名。） + +有人在最后加上标签。现在这些东西会被忽略，但是你可以这样做，来标记公司 +内部的过程，或者只是指出关于 sign-off 的一些特殊细节。 + +12）标准补丁格式 + +标准的补丁，标题行是： + Subject: [PATCH 001/123] 子系统:一句话概述 + +标准补丁的信体存在如下部分： + + - 一个 "from" 行指出补丁作者。 + + - 一个空行 + + - 说明的主体，这些说明文字会被拷贝到描述该补丁的永久改动记录里。 + + - 一个由"---"构成的标记行 + + - 不合适放到改动记录里的额外的注解。 + + - 补丁本身（diff 输出） + +标题行的格式，使得对标题行按字母序排序非常的容易 - 很多 e-mail 客户端都 +可以支持 - 因为序列号是用零填充的，所以按数字排序和按字母排序是一样的。 + +e-mail 标题中的“子系统”标识哪个内核子系统将被打补丁。 + +e-mail 标题中的“一句话概述”扼要的描述 e-mail 中的补丁。“一句话概述” +不应该是一个文件名。对于一个补丁系列（“补丁系列”指一系列的多个相关补 +丁），不要对每个补丁都使用同样的“一句话概述”。 + +记住 e-mail 的“一句话概述”会成为该补丁的全局唯一标识。它会蔓延到 git +的改动记录里。然后“一句话概述”会被用在开发者的讨论里，用来指代这个补 +丁。用户将希望通过 google 来搜索"一句话概述"来找到那些讨论这个补丁的文 +章。 + +一些标题的例子： + + Subject: [patch 2/5] ext2: improve scalability of bitmap searching + Subject: [PATCHv2 001/207] x86: fix eflags tracking + +"from" 行是信体里的最上面一行，具有如下格式： + From: Original Author + +"from" 行指明在永久改动日志里，谁会被确认为作者。如果没有 "from" 行，那 +么邮件头里的 "From: " 行会被用来决定改动日志中的作者。 + +说明的主题将会被提交到永久的源代码改动日志里，因此对那些早已经不记得和 +这个补丁相关的讨论细节的有能力的读者来说，是有意义的。 + +"---" 标记行对于补丁处理工具要找到哪里是改动日志信息的结束，是不可缺少 +的。 + +对于 "---" 标记之后的额外注解，一个好的用途就是用来写 diffstat，用来显 +示修改了什么文件和每个文件都增加和删除了多少行。diffstat 对于比较大的补 +丁特别有用。其余那些只是和时刻或者开发者相关的注解，不合适放到永久的改 +动日志里的，也应该放这里。 +使用 diffstat的选项 "-p 1 -w 70" 这样文件名就会从内核源代码树的目录开始 +，不会占用太宽的空间（很容易适合80列的宽度，也许会有一些缩进。） + +在后面的参考资料中能看到适当的补丁格式的更多细节。 + +------------------------------- +第二节 提示，建议和诀窍 +------------------------------- + +本节包含很多和提交到内核的代码有关的通常的"规则"。事情永远有例外...但是 +你必须真的有好的理由这样做。你可以把本节叫做Linus的计算机科学入门课。 + +1) 读 Document/CodingStyle + +Nuff 说过，如果你的代码和这个偏离太多，那么它有可能会被拒绝，没有更多的 +审查，没有更多的评价。 + +2) #ifdef 是丑陋的 +混杂了 ifdef 的代码难以阅读和维护。别这样做。作为替代，将你的 ifdef 放 +在头文件里，有条件地定义 "static inline" 函数，或者宏，在代码里用这些东 +西。让编译器把那些"空操作"优化掉。 + +一个简单的例子，不好的代码： + + dev = alloc_etherdev (sizeof(struct funky_private)); + if (!dev) + return -ENODEV; + #ifdef CONFIG_NET_FUNKINESS + init_funky_net(dev); + #endif + +清理后的例子: + +(头文件里) + #ifndef CONFIG_NET_FUNKINESS + static inline void init_funky_net (struct net_device *d) {} + #endif + +(代码文件里) + dev = alloc_etherdev (sizeof(struct funky_private)); + if (!dev) + return -ENODEV; + init_funky_net(dev); + +3) 'static inline' 比宏好 + +Static inline 函数相比宏来说，是好得多的选择。Static inline 函数提供了 +类型安全，没有长度限制，没有格式限制，在 gcc 下开销和宏一样小。 + +宏只在 static inline 函数不是最优的时候[在 fast paths 里有很少的独立的 +案例]，或者不可能用 static inline 函数的时候[例如字符串分配]。 +应该用 'static inline' 而不是 'static __inline__', 'extern inline' 和 +'extern __inline__' 。 + +4) 不要过度设计 + +不要试图预计模糊的未来事情，这些事情也许有用也许没有用："让事情尽可能的 +简单，而不是更简单"。 + +---------------- +第三节 参考文献 +---------------- + +Andrew Morton, "The perfect patch" (tpp). + + +Jeff Garzik, "Linux kernel patch submission format". + + +Greg Kroah-Hartman, "How to piss off a kernel subsystem maintainer". + + + + + +NO!!!!

[原发到linux-kernel的一封邮件] + +主要的窍门是有五年和这些烦人的oops消息打交道的经验;-) + +实际上，你有办法使它更简单。我有两个不同的方法： + + gdb /usr/src/linux/vmlinux + gdb> disassemble + +那是发现问题的简单办法，至少如果bug报告做的好的情况下（象这个一样-运行ksymoops +得到oops发生的函数及函数内的偏移）。 + +哦，如果报告发生的内核以相同的编译器和相似的配置编译它会有帮助的。 + +另一件要做的事是反汇编bug报告的“Code”部分：ksymoops也会用正确的工具来做这件事， +但如果没有那些工具你可以写一个傻程序： + + char str[] = "\xXX\xXX\xXX..."; + main(){} + +并用gcc -g编译它然后执行“disassemble str”（XX部分是由Oops报告的值-你可以仅剪切 +粘贴并用“\x”替换空格-我就是这么做的，因为我懒得写程序自动做这一切）。 + +另外，你可以用scripts/decodecode这个shell脚本。它的使用方法是： +decodecode < oops.txt + +“Code”之后的十六进制字节可能（在某些架构上）有一些当前指令之前的指令字节以及 +当前和之后的指令字节 + +Code: f9 0f 8d f9 00 00 00 8d 42 0c e8 dd 26 11 c7 a1 60 ea 2b f9 8b 50 08 a1 +64 ea 2b f9 8d 34 82 8b 1e 85 db 74 6d 8b 15 60 ea 2b f9 <8b> 43 04 39 42 54 +7e 04 40 89 42 54 8b 43 04 3b 05 00 f6 52 c0 + +最后，如果你想知道代码来自哪里，你可以： + + cd /usr/src/linux + make fs/buffer.s # 或任何产生BUG的文件 + +然后你会比gdb反汇编更清楚的知道发生了什么。 + +现在，问题是把你所拥有的所有数据结合起来：C源码（关于它应该怎样的一般知识）， +汇编代码及其反汇编得到的代码（另外还有从“oops”消息得到的寄存器状态-对了解毁坏的 +指针有用，而且当你有了汇编代码你也能拿其它的寄存器和任何它们对应的C表达式做匹配 +）。 + +实际上，你仅需看看哪里不匹配（这个例子是“Code”反汇编和编译器生成的代码不匹配）。 +然后你须要找出为什么不匹配。通常很简单-你看到代码使用了空指针然后你看代码想知道 +空指针是怎么出现的，还有检查它是否合法.. + +现在，如果明白这是一项耗时的工作而且需要一丁点儿的专心，没错。这就是我为什么大多 +只是忽略那些没有符号表信息的崩溃报告的原因：简单的说太难查找了（我有一些 +程序用于在内核代码段中搜索特定的模式，而且有时我也已经能找出那些崩溃的地方，但是 +仅仅是找出正确的序列也确实需要相当扎实的内核知识） + +_有时_会发生这种情况，我仅看到崩溃中的反汇编代码序列， 然后我马上就明白问题出在 +哪里。这时我才意识到自己干这个工作已经太长时间了;-) + + Linus + + +--------------------------------------------------------------------------- +关于Oops跟踪的注解： + +为了帮助Linus和其它内核开发者，klogd纳入了大量的支持来处理保护错误。为了拥有对 +地址解析的完整支持至少应该使用1.3-pl3的sysklogd包。 + +当保护错误发生时，klogd守护进程自动把内核日志信息中的重要地址翻译成它们相应的符 +号。 + +klogd执行两种类型的地址解析。首先是静态翻译其次是动态翻译。静态翻译和ksymoops +一样使用System.map文件。为了做静态翻译klogd守护进程必须在初始化时能找到system +map文件。关于klogd怎样搜索map文件请参看klogd手册页。 + +动态地址翻译在使用内核可装载模块时很重要。 因为内核模块的内存是从内核动态内存池 +里分配的，所以不管是模块开始位置还是模块中函数和符号的位置都不是固定的。 + +内核支持允许程序决定装载哪些模块和它们在内存中位置的系统调用。使用这些系统调用 +klogd守护进程生成一张符号表用于调试发生在可装载模块中的保护错误。 + +至少klogd会提供产生保护错误的模块名。还可有额外的符号信息供可装载模块开发者选择 +以从模块中输出符号信息。 + +因为内核模块环境可能是动态的，所以必须有一种机制当模块环境发生改变时来通知klogd +守护进程。 有一些可用的命令行选项允许klogd向当前执行中的守护进程发送信号，告知符 +号信息应该被刷新了。 更多信息请参看klogd手册页。 + +sysklogd发布时包含一个补丁修改了modules-2.0.0包，无论何时一个模块装载或者卸载都 +会自动向klogd发送信号。打上这个补丁提供了必要的对调试发生于内核可装载模块的保护 +错误的无缝支持。 + +以下是被klogd处理过的发生在可装载模块中的一个保护错误例子： +--------------------------------------------------------------------------- +Aug 29 09:51:01 blizard kernel: Unable to handle kernel paging request at virtual address f15e97cc +Aug 29 09:51:01 blizard kernel: current->tss.cr3 = 0062d000, %cr3 = 0062d000 +Aug 29 09:51:01 blizard kernel: *pde = 00000000 +Aug 29 09:51:01 blizard kernel: Oops: 0002 +Aug 29 09:51:01 blizard kernel: CPU: 0 +Aug 29 09:51:01 blizard kernel: EIP: 0010:[oops:_oops+16/3868] +Aug 29 09:51:01 blizard kernel: EFLAGS: 00010212 +Aug 29 09:51:01 blizard kernel: eax: 315e97cc ebx: 003a6f80 ecx: 001be77b edx: 00237c0c +Aug 29 09:51:01 blizard kernel: esi: 00000000 edi: bffffdb3 ebp: 00589f90 esp: 00589f8c +Aug 29 09:51:01 blizard kernel: ds: 0018 es: 0018 fs: 002b gs: 002b ss: 0018 +Aug 29 09:51:01 blizard kernel: Process oops_test (pid: 3374, process nr: 21, stackpage=00589000) +Aug 29 09:51:01 blizard kernel: Stack: 315e97cc 00589f98 0100b0b4 bffffed4 0012e38e 00240c64 003a6f80 00000001 +Aug 29 09:51:01 blizard kernel: 00000000 00237810 bfffff00 0010a7fa 00000003 00000001 00000000 bfffff00 +Aug 29 09:51:01 blizard kernel: bffffdb3 bffffed4 ffffffda 0000002b 0007002b 0000002b 0000002b 00000036 +Aug 29 09:51:01 blizard kernel: Call Trace: [oops:_oops_ioctl+48/80] [_sys_ioctl+254/272] [_system_call+82/128] +Aug 29 09:51:01 blizard kernel: Code: c7 00 05 00 00 00 eb 08 90 90 90 90 90 90 90 90 89 ec 5d c3 +--------------------------------------------------------------------------- + +Dr. G.W.
