* s3: vfs_dirsort module.Jeremy Allison2014-02-121-7/+112
| | | | | | | | | | | | | | | | | | | | | | | Allow dirsort to work when multiple simultaneous directories are open. The old code only keeps one active private data pointer on the connection struct, opening a second directory on the same connection will overwrite it. This modification turns the private data pointer into a linked list of open directories on the connection struct, and finds the correct one by searching on the passed in DIR *. With this code in place, smbd passes raw.search torture test on a share definition with: vfs objects = dirsort https://bugzilla.samba.org/show_bug.cgi?id=10406 Signed-off-by: Jeremy Allison <jra@samba.org> Reviewed-by: Andrew Bartlett <abartlet@samba.org>

| | | | | | | | | | | | | The Linux CIFS client does not pass an updated atime when a write() is done. This causes the vfs/glusterfs module to set the atime to -1 on the Gluster backend, resulting in an atime far in the future (year 2106).

* s3: Avoid oplock break by storing timestamps with gpfs_set_timesChristof Schmitt2014-01-093-6/+69
| | | | | | | | | | | | | | | | The gpfs_set_times API call allows setting timestamps directly in GPFS without going through the utime() call. Using this API call fixes an unecessary oplock break when a client sends a SET_FILE_ALLOCATION_INFO request and no other client has opened the file. The call to utime() triggers the oplock break through the Linux kernel. Using the gpfs_set_times call for updating the timestamp avoids the call to utime() and the oplock break.

| | | | | | | | | | | | | | | | In Samba configuration file, one of the options of gluster type is log file, the value of this option was not allowed to contain any variables, as a result all the clients would have a single log file, which complicated debugging.

| | | | | | | | | | | | | | | I was being overly cautious. This is initialization is not necessary, since further down in the for-loop, the memory always gets fully initialized because the insert string is inserted at various slash positions. So this talloc_zero_array can be skipped: this an expensive thing to do in virtually every VFS call. This essentially reverts commit 249e9b4a34d8959bd94735c1921ecfc24d6a2705.

| | | | | | | | | | | | | | | The VFS interfaces are sychronous, as the operations only modify meta-data. These hooks are dependent on support for transparent compression by the underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST.
