ctdb-daemon: Run "startipreallocate" event in SHUTDOWN runstate
Even though all nodes may be shutting down there is still a very small
window for a race when multiple nodes are shut down. For simplicity,
assume 2 nodes. Assume the shutdowns of nodes are staggered, which is
usual because they're usually initiated by a loop (e.g. onnode -p all
ctdb shutdown). Although commands can continue in parallel, some
commands are started later than others.
Consider this sequence:
1. Node 0 reaches ctdb_shutdown_takeover() in
ctdb_shutdown_sequence() and a takeover run starts
2. Node 1 has not yet set its runlevel to SHUTDOWN in
ctdb_shutdown_sequence()
3. The leader node asks node 1 which IPs it can host
4. Node 1 replies "all of them"
5. Node 1 now sets its runlevel to SHUTDOWN in
ctdb_shutdown_sequence()
6. The leader node continues with the takeover run, first asking all
nodes to run "startipreallocate"
7. Node 0 runs "startipreallocate", so its NFS server starts grace
8. Node 1 does not run "startipreallocate" because it is not in
RUNNING runstate, so its NFS server does not start grace
9. The leader node continues with the takeover run, first asking all
nodes to run "releaseip" for IPs they can no longer hold
10. Node 0 releases all IPs, since it is SHUTDOWN runstate (so can't
host IPs)
11. As part of this, the NFS server on node 0 releases locks held
against IPs it is releasing
12. A client connected to node 1, where the NFS server is not in
grace, takes ("steals") one of those locks
This client is then permitted to reclaim the lock when nodes are
restarted.

ctdb-daemon: Avoid aborting during early shutdown
An early shutdown can put ctdbd into SHUTDOWN runstate before ctdbd
has completed all early initialisation. Some of the start-time
transitions then attempt to set the runstate to FIRST_RECOVERY or
RUNNING, which would make the runstate go backwards, so ctdbd aborts.
Upcoming changes cause ctdbd shutdown to take longer, so the problem
will become more likely. With those changes, this can be
unreliably (50% of the time?) triggered by:
since it does an early shutdown due to a version mismatch.
Avoid this by noticing when the runstate is SHUTDOWN and refusing to
continue with subsequent early initialisation steps, which aren't
needed when shutting down.
Earlier runstate transitions do not seems likely to cause an abort
during early shutdown. The following:
sees ctdbd already into FIRST_RECOVERY before the shutdown is
processed.
The change to ctdb_run_startup() probably isn't strictly necessary.
There will be no abort in this case. ctdb_shutdown_sequence() will
always run the "shutdown" event and then stop the event daemon, so it
doesn't seem possible that services could be left running. However,
we might as well avoid running the "startup" event when shutting down,
even if only to avoid confusing logs.
Ultimately, it seems like some redesign would be needed to avoid this
in a more predictable manner, rather than responding when an early
initialisation step inconveniently completes during shutdown. For
example, hanging a lot of the start-time event handling off a common
talloc context, could allow it to be cancelled with a single
TALLOC_FREE(). However, a change like that would involve a lot of
analysis to ensure that the talloc hierarchy is correct and there is
no change of free'd pointers being dereferenced. So, we're probably
better off just keeping this issue in mind during a broader redesign.

Use the same logic from shadow_copy2 module to always prepend the
connectpath to the relative snapshot path so as to return converted
path corresponding to the file's share root.
Please note that with the current working directory staying at the
connectpath level we are safe to prefix it to the smb_filename. In
other words it seems we never get past the connectpath internally
during normal file system operations via chdir(). Since all relative
paths are now based on dirfsp we could constitute absolute path by
prepending the connectpath to full_path_from_dirfsp_atname() output

vfs_ceph_snapshots: Use full path from dirfsp at smb_fname
In ceph_snap_gmt_openat() we hand in the incoming smb_fname as it is
to ceph_snap_gmt_strip_snapshot() which is then passed on to derive
the actual snapshot path using ceph_snap_gmt_convert(). But this can
go wrong in ceph_snap_gmt_convert_dir() while opening the snapdir.
Unless we constitute the full path from dirfsp at the first place we
always end up opening the snapdir from the parent directory with
OpenDir().
For example with dirfsp("foobar") and smb_fname("shift.txt"), we open
snapdir from share root because parent is calculated as empty string
via ceph_snap_get_parent_path(). Instead we could construct the full
path from dirfsp using full_path_from_dirfsp_atname() to ensure we
don't open the wrong snapdir.
Since we have access to the twrp token at VFS layer it doesn't make
much sense to make use of ceph_snap_gmt_strip_snapshot() in openat.
We could instead directly act based on already available twrp token
avoiding an extra copy of incoming smb_filename.

smbd: use share_mode_do_locked_brl()
Fix a deadlock that can happen if two clients happen to open and byte-range-lock
two different files whos record in locking.tdb and brlock.tdb happen to sit on
the same hashchain.
The deadlock was introduced by commit 680c7907325b433856ac1dd916ab63e671fbe4ab. Before, we used share_mode_do_locked()
in do_lock() which meant we acquired a chainlock on locking.tdb before getting a
chainlock on brlock.tdb via brl_get_locks_for_locking(), so the TDB chainlock
order invariant was always uphold.
The following race between specific client requests lead to the deadlock.
Client A) issues a byte-range-lock request on a file:
B1) glock and chainlock locking.tdb (via _share_mode_entry_prepare_lock())
B2) attempt to chainlock brlock.tdb (via file_has_brlocks())
[2]
The glock from A1 is per record and hence doesn't synchronize with the glock
from B1 as it is for a different file and hence a different record, subsequently
A2 and A3 violate the lock order constraint
To avoid the chainlock lock order violation in the second client we modify the
br-lock code to not take the brlock.tdb chainlock from step A2 via
br_get_locks() for the whole time we process the request. Instead we just fetch
the br-locks via br_get_locks_readonly(), so when running into
contend_level2_oplocks_begin_default() to check for leases and looking into
locking.tdb we don't hold a brlock.tdb chainlock.
Or im simpler terms, we only ever take at most one low-level TDB chainlock at a
time:
Byte-range-lock code calls share_mode_do_locked_brl(..., cb_fn, ...):
1) chainlock locking.tdb
2) glock locking.tdb (via share_mode_do_locked_vfs_allowed())
3) chainunlock locking.tdb
4) share_mode_do_locked_brl_fn() -> brl_get_locks_readonly_parse():
a) chainlock brlock.tdb
b) parse record and store in-memory copy
c) chainunlock brlock.tdb
5) run cb_fn()
6) chainlock brlock.tdb:
a) br_lck->record = dbwrap_fetch_locked(brlock_db, ...)
b) store modifed br_lck from 5) via byte_range_lock_flush()
7) chainunlock brlock.tdb
8) chainlock locking.tdb
9) gunlock locking.tdb
10) chainunlock locking.tdb
All access to brlock.tdb is synchronized correctly via glocks on the locking.tdb
record of the file (step 3)), so operations still appear atomic to clients.
As a result of using share_mode_do_locked_brl(), the functions do_[un]lock() ->
brl_[un]lock() now loop over the same br_lck object in memory, avoiding
repeatedly fetching and storing the locks per loop.

vfs_ceph_new: detect case sensitivity in CephFS

vfs_ceph_new: Do not resolve by inode number
CephFS snapshots within snap directory shares the same inode number from

an inode which is not a snapshot directory. Therefore to be functionally
correct we avoid resolving by inode number but proper name.

It can very well be the case that the incoming path is absolute in

vfs_ceph_new: use libcephfs nonblocking API for async-io ops
Use libcephfs non-blocking API (ceph_ll_nonblocking_readv_writev[1]) in
combination with smb VFS async hooks ({pread,pwrite,fsync}_send/_recv).
Fills libcephfs' struct ceph_ll_io_info with single iovec and
submit/complete the operation asynchronously on libcephfs side, with
corresponding tevent schedule-immediate upon completion on smbd side.
Control nonblocking/normal I/O mode via config parameter. The common
parts of async I/O (with/without HAVE_CEPH_ASYNCIO) are united.
Specifically, use same struct vfs_ceph_aio_state and common code via
helper function for all async I/O hooks. When HAVE_CEPH_ASYNCIO
is True _and_ config option 'asyncio = yes' use libcephfs asynchronous
I/O API. Otherwise, fake async operation using normal blocking APIs.
s3:utils: Remove call of ads_startup() from net_ads_keytab_create()
Calling ads_startup() is not needed in net_ads_keytab_create. Keytab
creation code in sync_pw2keytabs() decides if it needs to talk to DC or
not and connects to AD accordingly.
Fixing this, makes the bug below easier to reproduce using
'net ads keytab create'.
