glusterfsd: Memleak in glusterfsd process while brick mux is on

2018-04-06T12:47:34+00:00

Problem: At the time of stopping the volume while brick multiplex is
         enabled memory is not cleanup from all server side xlators.

Solution: To cleanup memory for all server side xlators call fini
          in glusterfs_handle_terminate after send GF_EVENT_CLEANUP
          notification to top xlator.

feature/bitrot: remove internal xattrs from lookup cbk

2017-12-19T04:39:05+00:00

Problem:
afr requests all xattrs in lookup via the list-xattr key. If bitrot is
enabled and later disabled, or if the bitrot xattrs were present due to
an older version of bitrot which used to create the xattrs without
enabling the feature, the xattrs (trusted.bit-rot.version in particular)
was not getting filtered and ended up reaching the client stack. AFR, on
noticing different values of the xattr across bricks of the replica,
started triggering spurious metadata heals.

Fix:
Filter all internal xattrs in bitrot xlator before unwinding lookup,
(f)getxattr.

Thanks to Kotresh for the help in RCA'ing.

features/worm: Adding check to newloc when doing rename

2017-10-25T14:07:19+00:00

Problem: Since rename didn't check if newloc exists and it's
retention state it was possible to rename a new file that wasn't
in retention over a existing file that was in read-only state.

libgfchangelog: Fix possible null pointer dereference

2017-10-25T11:38:12+00:00

If pthread_attr_init fails, gf_msg uses this->name
where 'this' is not initialized yet. This patch fixes
the same.

features/locks: Maintain separation of lock->client_pid, flock->l_pid

2017-10-06T06:30:35+00:00

Problem:
grant_blocked_locks() constructs flock from lock. Locks xlator uses
frame->root->pid interchangeably flock->l_pid. With gNFS frame->root->pid
(which translates to lock->client_pid) is not same as flock->l_pid, this leads
to lk's cbk returning flock with l_pid from lock->client_pid instead of input
flock->l_pid. This triggers EC's error code path leading to failure of lk call,
because the response' flock->l_pid is different from request's flock->l_pid.

Fix:
Maintain separation of lock->client_pid, flock->l_pid. Always unwind with
flock with correct pid.

arbiter: return ENOSYS for 'non readable' FOPs

2017-09-10T18:34:38+00:00

AFR marks the arbiter as 'non readable'. This has been introduced with
commit 8ab87137 (afr: do not set arbiter as a readable subvol in inode
context). arbiter_readv() should not get called anymore, so it could be
removed. However, it is a good defensive approach to have all the inode
read FOPs that can not be handled by the arbiter to return ENOSYS.
