c99402724a s3-vfs: Use ENOATTR in errno comparison for getxattr
* ENODATA is not defined in FreeBSD
* ENOATTR is defined to be a synonym for ENODATA in Linux
* In its absence Samba already defines ENOATTR to either
  ENODATA or ENOENT

Thus it is safe and correct to compare with ENOATTR rather

0736fdcdb0 smbd: use async dos_mode_at_send in smbd_smb2_query_directory_send()
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.

732ba3c84a vfs_glusterfs: include glusterfs/api/glfs.h without relying on -I options
BUG: https://bugzilla.samba.org/show_bug.cgi?id=13125

The glfs.h header file has always resided under glusterfs/api/ in the
standard include directory. The glusterfs-api.pc file adds the unneeded
-I${includedir}/glusterfs compiler option. This option will be removed
from future versions of the pkg-config file.

This change can safely be backported to older versions if there is a
need to have them build against glusterfs-3.13 or newer.

1249801ec7 vfs_glusterfs: Fix exporting subdirs with shadow_copy2
Since the glusterfs vfs module does not operate on a
locally mounted path, but on a "virtual" path starting
at the volume root, some assumptions of the code about
the vfs connect path fail. One example is the shadow_copy2
module which tries to detect the mount point from the
connectpath. In order to circumvent this problem, this
patch forces the "shadow:mountpoint" option to "/", which
skips the mount-point-detection code.

This patch will only have an effect if both the glusterfs
and the shadow_copy2 module are listed in vfs objects
in the right order, i.e. first shadow_copy2, and then
glusterfs.

857745655b support volfile fetch from multiple glusterd nodes
glusterfs:volfile_server option can be used in smb.conf to define where
to fetch the volfile from. Currently it supports only a single IP or a
hostname. The default is 'localhost'.

glfs_set_volfile_server() has been enhanced in gfapi to support
multiple invocations. A list is maintained in libgfapi which gets
appended on every invocation. When glfs_init is performed, libgfapi
would first try to fetch the volfile from glusterd on that node.
However, on failure to fetch the volfile, it would proceed to contact
glusterd on every node in the list until it gets the volfile or
exhausts the list. This enhacement was done in Gluster commit [2].
This commit is available in 3.6, 3.7, 3.8 versions of Gluster.

As we cannot have multiple lines having the same key of
glusterfs:volfile_server in a share definition in smb.conf, we propose
a scheme like this:

where value of glusterfs:volfile_server could be list of white space seperated
elements where each element could be unix+/path/to/socket/file or
[tcp+]IP|hostname|\[IPv6\][:port].

Note the restriction on naming a IPv6 host, it follows the same
restriction that is based on IPv6 naming in URL as per RFC 2732[1].

12c0b6bf40 s3/vfs: change fallocate mode flags from enum->uint32_t
The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)

The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.

Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

variables, as a result all the clients would have a single log file,
which complicated debugging.
In this patch, variable substitution is performed for gluster log file.
Hence allowing user to customise the gluster log file name.

ba04400d01 vfs_glusterfs: Fix excessive debug output from vfs_gluster_open().
The vfs_gluster_open() function generates a debug message (at level 0)
for every failed attempt to open a pathname.  This includes cases in
which attempts are made to open a directory as a file (those attempts
are retried calling vfs_gluster_opendir()).  The result is that the log
file fills with messages about failed attempts to open directories, just
because they are directories.

This latest version, of the patch completely removes logging from the
vfs_gluster_open() function.  The error code returned is handled in
upper layers, and the open function in the default VFS module does not
log any errors.

This is a "bottom" vfs plugin (not something to be stacked on top of
