uuid,afs: move struct uuid_v1 back into afs

2017-06-05T14:56:34Z

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 generation

2017-02-10T16:34:17Z

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.h

2017-02-10T16:34:17Z

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 Reviewed-by: Arnd Bergmann

afs: Add some tracepoints

2017-01-09T09:18:13Z

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

AFS: Correctly assemble the client UUID

Correctly assemble the client UUID by OR'ing in the flags rather than assigning them over the other components. Reported-by: Himangi Saraogi Signed-off-by: David Howells Signed-off-by: Linus Torvalds

afs: add afs_wq and use it instead of the system workqueue

2011-01-14T17:25:11Z

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 handling

2010-08-07T21:23:37Z

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: [] destroy_workqueue+0x17/0xc0 ...
