proc: convert everything to "struct proc_ops"

2020-02-04T03:05:26+00:00

The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in seq_file.h. Conversion rule is: llseek => proc_lseek unlocked_ioctl => proc_ioctl xxx => proc_xxx delete ".owner = THIS_MODULE" line [akpm@linux-foundation.org: fix drivers/isdn/capi/kcapi_proc.c] [sfr@canb.auug.org.au: fix kernel/sched/psi.c] Link: http://lkml.kernel.org/r/20200122180545.36222f50@canb.auug.org.au Link: http://lkml.kernel.org/r/20191225172546.GB13378@avx2 Signed-off-by: Alexey Dobriyan Signed-off-by: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

NFSv4.1: Don't rebind to the same source port when reconnecting to the server

2019-11-04T02:28:45+00:00

NFSv2, v3 and NFSv4 servers often have duplicate replay caches that look at the source port when deciding whether or not an RPC call is a replay of a previous call. This requires clients to perform strange TCP gymnastics in order to ensure that when they reconnect to the server, they bind to the same source port. NFSv4.1 and NFSv4.2 have sessions that provide proper replay semantics, that do not look at the source port of the connection. This patch therefore ensures they can ignore the rebind requirement.

lockd: Make two symbols static

2019-07-03T21:52:09+00:00

Fix sparse warnings: fs/lockd/clntproc.c:57:6: warning: symbol 'nlmclnt_put_lockowner' was not declared. Should it be static? fs/lockd/svclock.c:409:35: warning: symbol 'nlmsvc_lock_ops' was not declared. Should it be static? Reported-by: Hulk Robot Signed-off-by: YueHaibing Signed-off-by: J.

lockd: Show pid of lockd for remote locks

2019-07-03T21:52:09+00:00

Use the pid of lockd instead of the remote lock's svid for the fl_pid for local POSIX locks. This allows proper enumeration of which local process owns which lock. The svid is meaningless to local lock readers. Signed-off-by: Benjamin Coddington Signed-off-by: J. Bruce Fields

lockd: Remove lm_compare_owner and lm_owner_key

2019-07-03T21:52:08+00:00

Now that the NLM server allocates an nlm_lockowner for fl_owner, there's no need for special hashing or comparison. Signed-off-by: Benjamin Coddington Signed-off-by: J. Bruce Fields

lockd: Convert NLM service fl_owner to nlm_lockowner

2019-07-03T21:52:08+00:00

Do as the NLM client: allocate and track a struct nlm_lockowner for use as the fl_owner for locks created by the NLM sever. This allows us to keep the svid within this structure for matching locks, and will allow us to track the pid of lockd in a future patch. It should also allow easier reference of the nlm_host in conflicting locks, and simplify lock hashing and comparison.

lockd: prepare nlm_lockowner for use by the server

2019-07-03T21:52:08+00:00

The nlm_lockowner structure that the client uses to track locks is generally useful to the server as well. Very similar functions to handle allocation and tracking of the nlm_lockowner will follow. Rename the client functions for clarity. Signed-off-by: Benjamin Coddington Signed-off-by: J. Bruce Fields

Revert "lockd: Show pid of lockd for remote locks"

2019-05-31T13:43:26+00:00

This reverts most of commit b8eee0e90f97 ("lockd: Show pid of lockd for remote locks"), which caused remote locks to not be differentiated between remote processes for NLM. We retain the fixup for setting the client's fl_pid to a negative value.
