s3:tests: Improve debugging for test_wbinfo_lookuprids_cache.sh

2026-04-22T16:35:58+00:00

Note that if this test fails, it is like something else creating keys.
The last time it was a crashing smbd which left a key in the database
and this test failed as a result.

vfs_ceph_new: remove double-cleanup in closedir

2026-04-21T22:18:42+00:00

vfs_ceph_release_fh() was called explicitly then again via the FSP
extension destructor triggered by vfs_ceph_remove_fh(). Drop the
explicit call and let the destructor handle cleanup.

vfs_ceph_new: fix return type mismatch in disk_free

2026-04-21T21:15:30+00:00

-ENOMEM cast to uint64_t is not the error sentinel UINT64_MAX and
leaves errno unset. Set errno and return UINT64_MAX instead.
Also replace UINT64_MAX instead of (uint64_t)-1) in all error path.

The functions 'brl_lock_windows_default' and 'brl_lock_posix' uses
explicit 'errno_ret' value to avoid possible errno overwrite. Use in

smbdotconf: Add "automount fs types" to smb.conf

2026-04-20T19:57:42+00:00

This adds a new global parameter "automount fs types" that allows
administrators to configure additional filesystem types that should
trigger automounting, beyond the always-supported autofs filesystem.

To enable 'samba unaware FS' automounting, add:

    automount fs types = 0x12345678

This allows e.g. ZFS snapshots in /.zfs/snapshot to be
mounted. To find out the magic number that is not listed
in /usr/include/linux/magic.h, run:

    stat -f -c '0x%t' /path/to/mountpoint

This avoids mixing malloc and talloc allocation patterns and

snapper_gmt_fstatat is failing when called on items in a
'previous version' snapshot because the wrong timestamp value is
passed (the raw timewarp value is used) and snapper_gmt_convert cannot
find the valid snapshot instance to use.
