* uuid,afs: move struct uuid_v1 back into afsChristoph Hellwig2017-06-051-1/+1
| | | | | | | | | | | | | | | This essentially is a partial revert of commit ff548773 ("afs: Move UUID struct to linux/uuid.h") and moves struct uuid_v1 back into fs/afs as struct afs_uuid. It however keeps it as big endian structure so that we can use the normal uuid generation helpers when casting to/from struct afs_uuid. The V1 uuid intrepretation in struct form isn't really useful to the rest of the kernel, and not really compatible to it either, so move it back to AFS instead of polluting the global uuid.h.

* afs: Use core kernel UUID generationArnd Bergmann2017-02-101-47/+1
| | | | | | | | | | | | | AFS uses a time based UUID to identify the host itself. This requires getting a timestamp which is currently done through the getnstimeofday() interface that we want to eventually get rid of. Instead of replacing it with a ktime-based interface, simply remove the entire function and use generate_random_uuid() instead, which has a v4 ("completely random") UUID instead of the time-based one.

* afs: Move UUID struct to linux/uuid.hDavid Howells2017-02-101-12/+13
| | | | | | | | | Move the afs_uuid struct to linux/uuid.h, rename it to uuid_v1 and change the u16/u32 fields to __be16/__be32 instead so that the structure can be cast to a 16-octet network-order buffer. Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de
* afs: Add some tracepointsDavid Howells2017-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Add three tracepoints to the AFS filesystem: (1) The afs_recv_data tracepoint logs data segments that are extracted from the data received from the peer through afs_extract_data(). (2) The afs_notify_call tracepoint logs notification from AF_RXRPC of data coming in to an asynchronous call. (3) The afs_cb_call tracepoint logs incoming calls that have had their operation ID extracted and mapped into a supported cache manager service call. To make (3) work, the name strings in the afs_call_type struct objects have to be annotated with __tracepoint_string. This is done with the CM_NAME() macro. Further, the AFS call state enum needs a name so that it can be used to declare parameter types. Signed-off-by: David Howells <dhowells@redhat.com>

* afs: add afs_wq and use it instead of the system workqueueTejun Heo2011-01-141-2/+11
| | | | | | | | | | | | | | | flush_scheduled_work() is going away. afs needs to make sure all the works it has queued have finished before being unloaded and there can be arbitrary number of pending works. Add afs_wq and use it as the flush domain instead of the system workqueue. Also, convert cancel_delayed_work() + flush_scheduled_work() to cancel_delayed_work_sync() in afs_mntpt_kill_timer().

* AFS: Fix the module init error handlingDavid Howells2010-08-071-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the module init error handling. There are a bunch of goto labels for aborting the init procedure at different points and just undoing what needs undoing - they aren't all in the right places, however. This can lead to an oops like the following: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 IP: [<ffffffff81042a31>] destroy_workqueue+0x17/0xc0 ...

* Detach sched.h from mm.hAlexey Dobriyan2007-05-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

* AFS: AFS fixupsDavid Howells2007-05-091-0/+2
| | | | | | | | | | | | | | | | | | | | | Make some miscellaneous changes to the AFS filesystem: (1) Assert RCU barriers on module exit to make sure RCU has finished with callbacks in this module. (2) Correctly handle the AFS server returning a zero-length read. (3) Split out data zapping calls into one function (afs_zap_data). (4) Rename some afs_file_*() functions to afs_*() where they apply to non-regular files too. (5) Be consistent about the presentation of volume ID:vnode ID in debugging output.

* [AFS]: Adjust the new netdevice scanning codeDavid Howells2007-05-031-1/+1
| | | | | | | | | | | | | | | | | Adjust the new netdevice scanning code provided by Patrick McHardy: (1) Restore the function banner comments that were dropped. (2) Rather than using an array size of 6 in some places and an array size of ETH_ALEN in others, pass a pointer instead and pass the array size through so that we can actually check it. (3) Do the buffer fill count check before checking the for_primary_ifa condition again. This permits us to skip that check should maxbufs be reached before we run out of interfaces.

* [AFS]: Add support for the CB.GetCapabilities operation.David Howells2007-04-261-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | Add support for the CB.GetCapabilities operation with which the fileserver can ask the client for the following information: (1) The list of network interfaces it has available as IPv4 address + netmask plus the MTUs. (2) The client's UUID. (3) The extended capabilities of the client, for which the only current one is unified error mapping (abort code interpretation). To support this, the patch adds the following routines to AFS: (1) A function to iterate through all the network interfaces using RTNETLINK to extract IPv4 addresses and MTUs. (2) A function to iterate through all the network interfaces using RTNETLINK to pull out the MAC address of the lowest index interface to use in UUID construction.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+286
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
