A flaw was found in the IA32 system call emulation provided
on AMD64 and Intel 64 platforms. An improperly validated 64-bit
value could be stored in the %RAX register, which could trigger an

Details : In filter_check_grant, for non_grant cache write, we should
check the left space by if (*left > ungranted + bytes), instead
of (*left > ungranted), because only we are sure the left space
is enough for another "bytes", then the ungrant space should be

Severity : enhancement
Bugzilla : 10768
Description: 64-bit inode version
Details: : Add a on-disk 64-bit inode version for ext3 to track changes made
to the inode. This will be required for version-based recovery.
Severity : normal
Frequency : rare
Bugzilla : 11818
Description: MDS fails to start if a duplicate client export is detected
Details : in some rare cases it was possible for a client to connect to
an MDS multiple times. Upon recovery the MDS would detect this
and fail during startup. Handle this more gracefully.
Severity : enhancement
Bugzilla : 11563
Description: Add -o localflock option to simulate old noflock
behaviour.
Details : This will achieve local-only flock/fcntl locks
coherentness.
Severity : minor
Frequency : rare
Bugzilla : 11658
Description: log_commit_thread vs filter_destroy race leads to crash
Details : Take import reference before releasing llog record semaphore
Severity : normal
Frequency : rare
Bugzilla : 12477
Description: Wrong request locking in request set processing
Details : ptlrpc_check_set wrongly uses req->rq_lock for proctect add to
imp_delayed_list, in this place should be used imp_lock.
Severity : normal
Frequency : when reconnection
Bugzilla : 11662
Description: Grant Leak when osc reconnect to OST
Details : When osc reconnect ost, OST(filter) should check whether it
should grant more space to client by comparing fed_grant and
cl_avail_grant, and return the granted space to client instead
of "new granted" space, because client will call osc_init_grant
to update the client grant space info.
Severity : normal
Frequency : when client reconnect to OST
Bugzilla : 11662
Description: Grant Leak when osc do resend and replay bulk write
Details : When osc reconnect to OST, OST(filter)should clear grant info of
bulk write request, because the grant info while be sync between
OSC and OST when reconnect, and we should ignore the grant info
these of resend/replay write req.
Severity : normal
Frequency : rare
Bugzilla : 11662
Description: Grant space more than avaiable left space sometimes.
Details : When then OST is about to be full, if two bulk writing from
different clients came to OST. Accord the avaliable space of the
OST, the first req should be permitted, and the second one
should be denied by ENOSPC. But if the seconde arrived before
the first one is commited. The OST might wrongly permit second
writing, which will cause grant space > avaiable space.
Severity : normal
Frequency : when client is evicted
Bugzilla : 12371
Description: Grant might be wrongly erased when osc is evicted by OST
Details : when the import is evicted by server, it will fork another
thread ptlrpc_invalidate_import_thread to invalidate the
import, where the grant will be set to 0. While the original
thread will update the grant it got when connecting. So if
the former happened latter, the grant will be wrongly errased
because of this race.
Severity : normal
Frequency : rare
Bugzilla : 12401
Description: Checking Stale with correct fid
Details : ll_revalidate_it should uses de_inode instead of op_data.fid2
to check whether it is stale, because sometimes, we want the
enqueue happened anyway, and op_data.fid2 will not be initialized.
Severity : enhancement
Bugzilla : 11647
Description: update patchless client
Details : Add support for patchless client with 2.6.20, 2.6.21 and RHEL 5
Severity : normal
Frequency : only with 2.4 kernel
Bugzilla : 12134
Description: random memory corruption
Details : size of struct ll_inode_info is to big for union inode.u and this
can be cause of random memory corruption.
Severity : normal
Frequency : rare
Bugzilla : 10818
Description: Memory leak in recovery
Details : Lov_mds_md was not free in an error handler in mds_create_object.
It should also check obd_fail before fsfilt_start, otherwise if
fsfilt_start return -EROFS,(failover mds during mds recovery).
then the req will return with repmsg->transno = 0 and rc = EROFS.
and we met hit the assert LASSERT(req->rq_reqmsg->transno ==
req->rq_repmsg->transno) in ptlrpc_replay_interpret. Fcc should
be freed no matter whether fsfilt_commit success or not.
Severity : minor
Frequency : only with huge count clients
Bugzilla : 11817
Description: Prevents from taking the superblock lock in llap_from_page for
a soon died page.
Details : using LL_ORIGIN_REMOVEPAGE origin flag instead of LL_ORIGIN_UNKNOW
for llap_from_page call in ll_removepage prevents from taking the
superblock lock for a soon died page.
Severity : normal
Frequency : rare
Bugzilla : 11935
Description: Not check open intent error before release open handle
Details : in some rare cases, the open intent error is not checked before
release open handle, which may cause
ASSERTION(open_req->rq_transno != 0), because it tries to release
the failed open handle.
Severity : normal
Frequency : rare
Bugzilla : 12556
Description: Set cat log bitmap only after create log success.
Details : in some rare cases, the cat log bitmap is set too early. and it
should be set only after create log success.
Severity : major
Bugzilla : 11971
Description: Accessing a block bevice can re-enable I/O when Lustre is
tearing down a device.
Details : dev_clear_rdonly(bdev) must be called in kill_bdev() instead of
blkdev_put().
Severity : minor
Bugzilla : 11706
Description: service threads may hog cpus when there are a lot of requests
Details : Insert cond_resched to give other threads a chance to use some CPU
Severity : normal
Frequency : rare
Bugzilla : 12086
Description: the cat log was not initialized in recovery
Details : When mds(mgs) do recovery, the tgt_count might be zero, so the
unlink log on mds will not be initialized until mds post
recovery. And also in mds post recovery, the unlink log will
initialization will be done asynchronausly, so there will be race
between add unlink log and unlink log initialization.
Severity : normal
Bugzilla : 12597
Description: brw_stats were being printed incorrectly
Details : brw_stats were being printed as log2 but all of them were not
recorded as log2. Also remove some code duplication arising from
filter_tally_{read,write}.
Severity : normal
Bugzilla : 11674
Frequency : rare, only in recovery.
Description: ASSERTION(req->rq_type != LI_POISON) failed
Details : imp_lock should be held while iterating over imp_sending_list for
prevent destroy request after get timeout in ptlrpc_queue_wait.
Severity : normal
Bugzilla : 12689
Description: replay-single.sh test 52 fails
Details : A lock's skiplist need to be cleanup when it being unlinked
Severity : normal
Bugzilla : 11737
Description: Short directio read returns full requested size rather than
Details : Direct I/O operations should return actual amount of bytes
Severity : enhancement
Bugzilla : 10589
Description: metadata RPC reduction (e.g. for rm performance)
Details : decrease the amount of synchronous RPC between clients and servers
by canceling conflicing lock before the operation on the client
and packing thier handles into the main operation RPC to server.
Severity : enhancement
Bugzilla : 4900
Description: Async OSC create to avoid the blocking unnecessarily.
Details : If a OST has no remain object, system will block on the creating
when need to create a new object on this OST. Now, ways use
pre-created objects when available, instead of blocking on an
empty osc while others are not empty. If we must block, we block
for the shortest possible period of time.
Severity : enhancement
Bugzilla : 12702
Description: refine locking for avoid write wrong info into lov_objid file
Details : fix possible races with add new target and write/update data in
lov_objid file.

Description: 1.6 client sometimes fails to mount from a 1.4 MDT
Details : Uninitialized flags sometimes cause configuration commands to
be skipped.
Severity : normal
Frequency : patchless clients only
Bugzilla : 12391
Description: missing __iget() symbol export
Details : The __iget() symbol export is missing. To avoid the need for
this on patchless clients the deathrow inode reaper is turned
off, and we depend on the VM to clean up old inodes. This
dependency was during via the fix for bug 12181.
