While chasing a bug in g_lock (not in master) I saw some opportunity to
simplify g_lock_trylock a bit. This is array handling, and array
handling is just extremely error-prone. This *might* be a little less
efficient or large numbers of READ locks, but this remains to be
seen. For now, simplify the code.
First, we make two passes now: One to remove ourselves, and the other
one to search for conflicts. Mixing up both made it pretty hard for me
to follow the code.
Second, I've removed the _mylock and mylock pointer/struct logic and
replaced it with the "mylock.pid.pid != 0 ? &mylock : NULL" when calling
g_lock_store. To me, this focuses the logic whether to add ourselves in
one place instead of spreading it around in the whole routine.

The current implementation of `rmdir` hopes to get the directory deleted
on closing last open handle when FILE_DELETE_ON_CLOSE is set on it. But
for non-empty directories Windows doesn't error out during an open call.
Following that we internally refuse to set initial delete_on_close while
opening a non-empty directory. This prevents us from trying to delete
the directory when last open handle is closed.
Instead of relying on FILE_DELETE_ON_CLOSE during an open we explicitly
set delete_on_close token on directory handle once it is available. This
ensures that NT_STATUS_DIRECTORY_NOT_EMPTY is returned for `rmdir` on
non-empty directories while closing open directory handle.

Finally: use the new dos_mode_at_send() in the directory enumeration
loop. This means that fetching the DOS attributes for directory entries
is done asynchronously with regard to the enumeration loop.
As the DOS attribute is typically read from an extended attribute in the
filesytem, this avoids sequentially blocking on IO. If the IO subsystem
is slow servicing these request, enabling async processing can result in
performance improvements.
A parametric option
smbd:async dosmode = true | false (default: false)
can be used to enable the new async processing.
Simulating slow IO with usleep(5000) in the synchronous and asynchronous
versions of SMB_VFS_GET_DOS_ATTRIBUTES(), the results of enumerating a
directory with 10,000 files are:
smbd:async dosmode = no:
$ time bin/smbclient -U slow%x //localhost/test -c "ls dir\*" > /dev/null
real 0m59.597s
user 0m0.024s
sys 0m0.012s
smbd:async dosmode = yes:
$ time bin/smbclient -U slow%x //localhost/test -c "ls dir\*" > /dev/null
real 0m0.698s
user 0m0.038s
sys 0m0.025s
Performance gains in real world workloads depends on whether the actual
IO requests can be merged and parallelized by the kernel. Without such
wins at the IO layer, the async processing may even be slower then the
sync processing due to the additional overhead.
The following parameters can be used to adapt async processing behaviour
for specific workloads and systems:
aio max threads = X (default: 100)
smbd:max async dosmode = Y (default: "aio max threads" * 2)
By default we have at most twice the number of async requests in flight
as threads provided by the underlying threadpool. This ensures a worker
thread that finishes a job can directly pick up a new one without going
to sleep.
It may be advisable to reduce the number of threads to avoid scheduling
overhead while also increasing "smbd:max async dosmode".
Note that we disable async processing for certain VFS modules in the VFS
connect function to avoid the overhead of triggering the sync fallback
in dos_mode_at_send(). This is done for VFS modules that implement the
sync SMB_VFS_GET_DOS_ATTRIBUTES(), but not the async version (gpfs), and
for VFS modules that don't share a real filesystem where fchdir() can be
used (ceph, gluster). It is disabled for catia, because we realized that
the catia name translation macros used on
fsps (CATIA_FETCH_FSP_[PRE|POST]_NEXT) have a bug (#13547).
We use threadpool = smb_vfs_ev_glue_tp_chdir_safe() and then
pthreadpool_tevent_max_threads(threadpool) to get the number of maximum
worker threads which matches the pool used by the low level
SMB_VFS_GETXATTRAT_[SEND|RECV] implementation in vfs_default.
This is a terrible abstraction leak that should be removed in the future
by maybe making it possible to ask a VFS function which threadpool it
uses, internally suporting chaining so VFS function FOO that internally
uses BAR can forward the question to BAR.
On a hyphotetical system that had a getxattrat(dirfd, path, ...)
syscall and at the same time doesn't support per-thread current working
directories (eg FreeBSD doesn't have the latter) but has support for
per-thread-credentials, pthreadpool_tevent_max_threads() on the
tp_chdir_safe threadpool returns 1.
So when hooking the hyphotetical getxattrat() into the async
SMB_VFS_GETXATTRAT_[SEND|RECV] implementation in an VFS module, the
implementation could use the tp_path_safe threadpool, but the SMB2
layer would use the wrong threadpool in the call to
pthreadpool_tevent_max_threads(), resulting in no parallelism.
