Some of the more advanced +chipsets are able to deal with these errors; these include PCI-E chipsets, +and the PCI-host bridges found on IBM Power4 and Power5-based pSeries +boxes. A typical action taken is to disconnect the affected device, +halting all I/O to it. The goal of a disconnection is to avoid system +corruption; for example, to halt system memory corruption due to DMA's +to "wild" addresses. Typically, a reconnection mechanism is also +offered, so that the affected PCI device(s) are reset and put back +into working condition. The reset phase requires coordination +between the affected device drivers and the PCI controller chip. +This document describes a generic API for notifying device drivers +of a bus disconnection, and then performing error recovery. +This API is currently implemented in the 2.6.16 and later kernels. + +Reporting and recovery is performed in several steps. First, when +a PCI hardware error has resulted in a bus disconnect, that event +is reported as soon as possible to all affected device drivers, +including multiple instances of a device driver on multi-function +cards. This allows device drivers to avoid deadlocking in spinloops, +waiting for some i/o-space register to change, when it never will. +It also gives the drivers a chance to defer incoming I/O as +needed. + +Next, recovery is performed in several stages. Most of the complexity +is forced by the need to handle multi-function devices, that is, +devices that have multiple device drivers associated with them. +In the first stage, each driver is allowed to indicate what type +of reset it desires, the choices being a simple re-enabling of I/O +or requesting a hard reset (a full electrical #RST of the PCI card). +If any driver requests a full reset, that is what will be done. + +After a full reset and/or a re-enabling of I/O, all drivers are +again notified, so that they may then perform any device setup/config +that may be required. After these have all completed, a final +"resume normal operations" event is sent out. + +The biggest reason for choosing a kernel-based implementation rather +than a user-space implementation was the need to deal with bus +disconnects of PCI devices attached to storage media, and, in particular, +disconnects from devices holding the root file system. If the root +file system is disconnected, a user-space mechanism would have to go +through a large number of contortions to complete recovery. Almost all +of the current Linux file systems are not tolerant of disconnection +from/reconnection to their underlying block device. By contrast, +bus errors are easy to manage in the device driver. Indeed, most +device drivers already handle very similar recovery procedures; +for example, the SCSI-generic layer already provides significant +mechanisms for dealing with SCSI bus errors and SCSI bus resets. + + +Detailed Design +--------------- +Design and implementation details below, based on a chain of +public email discussions with Ben Herrenschmidt, circa 5 April 2005. The error recovery API support is exposed to the driver in the form of a structure of function pointers pointed to by a new field in struct -pci_driver. The absence of this pointer in pci_driver denotes an -"non-aware" driver, behaviour on these is platform dependant. -Platforms like ppc64 can try to simulate pci hotplug remove/add. - -The definition of "pci_error_token" is not covered here. It is based on -Seto's work on the synchronous error detection. We still need to define -functions for extracting infos out of an opaque error token. This is -separate from this API. +pci_driver. A driver that fails to provide the structure is "non-aware", +and the actual recovery steps taken are platform dependent. The +arch/powerpc implementation will simulate a PCI hotplug remove/add. This structure has the form: - struct pci_error_handlers { - int (*error_detected)(struct pci_dev *dev, pci_error_token error); + int (*error_detected)(struct pci_dev *dev, enum pci_channel_state); int (*mmio_enabled)(struct pci_dev *dev); - int (*resume)(struct pci_dev *dev); int (*link_reset)(struct pci_dev *dev); int (*slot_reset)(struct pci_dev *dev); + void (*resume)(struct pci_dev *dev); }; -A driver doesn't have to implement all of these callbacks. The -only mandatory one is error_detected(). If a callback is not -implemented, the corresponding feature is considered unsupported. -For example, if mmio_enabled() and resume() aren't there, then the -driver is assumed as not doing any direct recovery and requires +The possible channel states are: +enum pci_channel_state { + pci_channel_io_normal, /* I/O channel is in normal state */ + pci_channel_io_frozen, /* I/O to channel is blocked */ + pci_channel_io_perm_failure, /* PCI card is dead */ +}; + +Possible return values are: +enum pci_ers_result { + PCI_ERS_RESULT_NONE, /* no result/none/not supported in device driver */ + PCI_ERS_RESULT_CAN_RECOVER, /* Device driver can recover without slot reset */ + PCI_ERS_RESULT_NEED_RESET, /* Device driver wants slot to be reset. */ + PCI_ERS_RESULT_DISCONNECT, /* Device has completely failed, is unrecoverable */ + PCI_ERS_RESULT_RECOVERED, /* Device driver is fully recovered and operational */ +}; + +A driver does not have to implement all of these callbacks; however, +if it implements any, it must implement error_detected().

Within this function and after it returns, the driver shouldn't do any new IOs. Called in task context. This is sort of a "quiesce" point.

A platform with +no slot reset capability may want to just "ignore" drivers that can't recover (disconnect them) and try to let other cards on the same segment recover.

These kernels provide +special resources and mechanisms to maintain these "threads". The Linux +kernel, in a clever and simple manner, does not make distinction +between processes and "threads". The kernel allows processes to share +resources and thus they can achieve legacy "threads" behavior without +requiring additional data structures and mechanisms in the kernel. The +power of implementing threads in this manner comes not only from +its simplicity but also from allowing application programmers to work +outside the confinement of all-or-nothing shared resources of legacy +threads. On Linux, at the time of thread creation using the clone system +call, applications can selectively choose which resources to share +between threads. + +unshare system call adds a primitive to the Linux thread model that +allows threads to selectively 'unshare' any resources that were being +shared at the time of their creation. unshare was conceptualized by +Al Viro in the August of 2000, on the Linux-Kernel mailing list, as part +of the discussion on POSIX threads on Linux. unshare augments the +usefulness of Linux threads for applications that would like to control +shared resources without creating a new process. unshare is a natural +addition to the set of available primitives on Linux that implement +the concept of process/thread as a virtual machine. + +2) Benefits +----------- +unshare would be useful to large application frameworks such as PAM +where creating a new process to control sharing/unsharing of process +resources is not possible. Since namespaces are shared by default +when creating a new process using fork or clone, unshare can benefit +even non-threaded applications if they have a need to disassociate +from default shared namespace. The following lists two use-cases +where unshare can be used. + +2.1 Per-security context namespaces +----------------------------------- +unshare can be used to implement polyinstantiated directories using +the kernel's per-process namespace mechanism. Polyinstantiated directories, +such as per-user and/or per-security context instance of /tmp, /var/tmp or +per-security context instance of a user's home directory, isolate user +processes when working with these directories. Using unshare, a PAM +module can easily setup a private namespace for a user at login. +Polyinstantiated directories are required for Common Criteria certification +with Labeled System Protection Profile, however, with the availability +of shared-tree feature in the Linux kernel, even regular Linux systems +can benefit from setting up private namespaces at login and +polyinstantiating /tmp, /var/tmp and other directories deemed +appropriate by system administrators. + +2.2 unsharing of virtual memory and/or open files +------------------------------------------------- +Consider a client/server application where the server is processing +client requests by creating processes that share resources such as +virtual memory and open files. Without unshare, the server has to +decide what needs to be shared at the time of creating the process +which services the request. unshare allows the server an ability to +disassociate parts of the context during the servicing of the +request. For large and complex middleware application frameworks, this +ability to unshare after the process was created can be very +useful. + +3) Cost +------- +In order to not duplicate code and to handle the fact that unshare +works on an active task (as opposed to clone/fork working on a newly +allocated inactive task) unshare had to make minor reorganizational +changes to copy_* functions utilized by clone/fork system call. +There is a cost associated with altering existing, well tested and +stable code to implement a new feature that may not get exercised +extensively in the beginning. However, with proper design and code +review of the changes and creation of an unshare test for the LTP +the benefits of this new feature can exceed its cost. + +4) Requirements +--------------- +unshare reverses sharing that was done using clone(2) system call, +so unshare should have a similar interface as clone(2). That is, +since flags in clone(int flags, void *stack) specifies what should +be shared, similar flags in unshare(int flags) should specify +what should be unshared. Unfortunately, this may appear to invert +the meaning of the flags from the way they are used in clone(2). +However, there was no easy solution that was less confusing and that +allowed incremental context unsharing in future without an ABI change. + +unshare interface should accommodate possible future addition of +new context flags without requiring a rebuild of old applications. +If and when new context flags are added, unshare design should allow +incremental unsharing of those resources on an as needed basis. + +5) Functional Specification +--------------------------- +NAME + unshare - disassociate parts of the process execution context + +SYNOPSIS + #include <sched.h> + + int unshare(int flags); + +DESCRIPTION + unshare allows a process to disassociate parts of its execution + context that are currently being shared with other processes. Part + of execution context, such as the namespace, is shared by default + when a new process is created using fork(2), while other parts, + such as the virtual memory, open file descriptors, etc, may be + shared by explicit request to share them when creating a process + using clone(2). + + The main use of unshare is to allow a process to control its + shared execution context without creating a new process. + + The flags argument specifies one or bitwise-or'ed of several of + the following constants. + + CLONE_FS + If CLONE_FS is set, file system information of the caller + is disassociated from the shared file system information. + + CLONE_FILES + If CLONE_FILES is set, the file descriptor table of the + caller is disassociated from the shared file descriptor + table. + + CLONE_NEWNS + If CLONE_NEWNS is set, the namespace of the caller is + disassociated from the shared namespace. + + CLONE_VM + If CLONE_VM is set, the virtual memory of the caller is + disassociated from the shared virtual memory. + +RETURN VALUE + On success, zero returned. On failure, -1 is returned and errno is + +ERRORS + EPERM CLONE_NEWNS was specified by a non-root process (process + without CAP_SYS_ADMIN). + + ENOMEM Cannot allocate sufficient memory to copy parts of caller's + context that need to be unshared. + + EINVAL Invalid flag was specified as an argument. + +CONFORMING TO + The unshare() call is Linux-specific and should not be used + in programs intended to be portable. + +SEE ALSO + clone(2), fork(2) + +6) High Level Design +-------------------- +Depending on the flags argument, the unshare system call allocates +appropriate process context structures, populates it with values from +the current shared version, associates newly duplicated structures +with the current task structure and releases corresponding shared +versions. Helper functions of clone (copy_*) could not be used +directly by unshare because of the following two reasons. + 1) clone operates on a newly allocated not-yet-active task + structure, where as unshare operates on the current active + task. Therefore unshare has to take appropriate task_lock() + before associating newly duplicated context structures + 2) unshare has to allocate and duplicate all context structures + that are being unshared, before associating them with the + current task and releasing older shared structures. Failure + do so will create race conditions and/or oops when trying + to backout due to an error. Consider the case of unsharing + both virtual memory and namespace. After successfully unsharing + vm, if the system call encounters an error while allocating + new namespace structure, the error return code will have to + reverse the unsharing of vm. As part of the reversal the + system call will have to go back to older, shared, vm + structure, which may not exist anymore. + +Therefore code from copy_* functions that allocated and duplicated +current context structure was moved into new dup_* functions. Now, +copy_* functions call dup_* functions to allocate and duplicate +appropriate context structures and then associate them with the +task structure that is being constructed. unshare system call on +the other hand performs the following: + 1) Check flags to force missing, but implied, flags + 2) For each context structure, call the corresponding unshare + helper function to allocate and duplicate a new context + structure, if the appropriate bit is set in the flags argument. + 3) If there is no error in allocation and duplication and there + are new context structures then lock the current task structure, + associate new context structures with the current task structure, + and release the lock on the current task structure. + 4) Appropriately release older, shared, context structures. + +7) Low Level Design +------------------- +Implementation of unshare can be grouped in the following 4 different +items: + a) Reorganization of existing copy_* functions + b) unshare system call service function + c) unshare helper functions for each different process context + d) Registration of system call number for different architectures + + 7.1) Reorganization of copy_* functions + Each copy function such as copy_mm, copy_namespace, copy_files, + etc, had roughly two components. The first component allocated + and duplicated the appropriate structure and the second component + linked it to the task structure passed in as an argument to the copy + function. The first component was split into its own function. + These dup_* functions allocated and duplicated the appropriate + context structure. The reorganized copy_* functions invoked + their corresponding dup_* functions and then linked the newly + duplicated structures to the task structure with which the + copy function was called. + + 7.2) unshare system call service function + * Check flags + Force implied flags. If CLONE_THREAD is set force CLONE_VM. + If CLONE_VM is set, force CLONE_SIGHAND. If CLONE_SIGHAND is + set and signals are also being shared, force CLONE_THREAD. If + CLONE_NEWNS is set, force CLONE_FS. + * For each context flag, invoke the corresponding unshare_* + helper routine with flags passed into the system call and a + reference to pointer pointing the new unshared structure + * If any new structures are created by unshare_* helper + functions, take the task_lock() on the current task, + modify appropriate context pointers, and release the + task lock. + * For all newly unshared structures, release the corresponding + older, shared, structures. + + 7.3) unshare_* helper functions + For unshare_* helpers corresponding to CLONE_SYSVSEM, CLONE_SIGHAND, + and CLONE_THREAD, return -EINVAL since they are not implemented yet. + For others, check the flag value to see if the unsharing is + required for that structure. If it is, invoke the corresponding + dup_* function to allocate and duplicate the structure and return + a pointer to it. + + 7.4) Appropriately modify architecture specific code to register the + the new system call. + +8) Test Specification +--------------------- +The test for unshare should test the following: + 1) Valid flags: Test to check that clone flags for signal and + signal handlers, for which unsharing is not implemented + yet, return -EINVAL. + 2) Missing/implied flags: Test to make sure that if unsharing + namespace without specifying unsharing of filesystem, correctly + unshares both namespace and filesystem information. + 3) For each of the four (namespace, filesystem, files and vm) + supported unsharing, verify that the system call correctly + unshares the appropriate structure. Verify that unsharing + them individually as well as in combination with each + other works as expected. + 4) Concurrent execution: Use shared memory segments and futex on + an address in the shm segment to synchronize execution of + about 10 threads. Have a couple of threads execute execve, + a couple _exit and the rest unshare with different combination + of flags. Verify that unsharing is performed as expected and + that there are no oops or hangs. + +9) Future Work +-------------- +The current implementation of unshare does not allow unsharing of +signals and signal handlers. Signals are complex to begin with and +to unshare signals and/or signal handlers of a currently running +process is even more complex. If in the future there is a specific +need to allow unsharing of signals and/or signal handlers, it can +be incrementally added to unshare without affecting legacy +applications using unshare. + diff --git a/Documentation/video4linux/CARDLIST.cx88 b/Documentation/video4linux/CARDLIST.cx88 index 56e194f1a0b..8bea3fbd054 100644 --- a/Documentation/video4linux/CARDLIST.cx88 +++ b/Documentation/video4linux/CARDLIST.cx88 @@ -42,4 +42,4 @@ 41 -> Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profile) [0070:9800,0070:9802] 42 -> digitalnow DNTV Live!
