2013-08-01Ensure gpfs kernel leases are wrapped in a become_root()/unbecome_root() pair.Ralph Wuerthner1-0/+6

2013-05-09vfs: Fix compile of vfs_gpfs.c.Alexander Werth1-18/+33
Since the smb4acl is now correctly allocated on mem_ctx and not the talloc stack frame we can free the stack frame correctly. And the chmod emulation code now needs the vfs handle since that is now required by the callback function to set the smb4acl.

2013-05-09vfs: Allocate SMB4ACL_T on an explict memory contextAndrew Bartlett1-8/+20
This ensures the caller knows exactly what the memory lifetime of this returned object is. This makes the NFSv4 ACL code consistent with the POSIX and NT ACL code, to avoid supprising developers who have worked on those other parts of the ACL code. Most of this patch is adding a memory context to the callers and passing it in. Andrew Bartlett Reviewed-by: Jeremy Allison <jra@samba.org>

2012-10-11smbd: Add mem_ctx to {f,}get_nt_acl VFS callAndrew Bartlett1-5/+9
This makes it clear which context the returned SD is allocated on, as a number of callers do not want it on talloc_tos(). As the ACL transformation allocates and then no longer needs a great deal of memory, a talloc_stackframe() call is used to contain the memory that is not returned further up the stack. Andrew Bartlett
2012-10-11smbd: Add mem_ctx to sys_acl_init() and all callersAndrew Bartlett1-10/+14
This changes from allocation on NULL to allocation on the supplied memory context. Currently that supplied context is talloc_tos() at the the final consumer of the ACL. Andrew Bartlett

2012-08-29s3:vfs_gpfs: Use directory not file to get fileset idChristof Schmitt1-2/+22
The query of the fileset quota needs to determine the file set id first. With the currently available interface, this requires opening the file to get a file descriptor. For files, this open can fail when a share mode is set. Workaround this by querying the fileset id on the directory instead. The proper solution would be getting an interface for getting the fileset id that does not require opening the file.

2012-08-15s3-smbd: Change allocation of smb_acl_t to talloc()Andrew Bartlett1-2/+2
The acl element is changed to be a talloc child, and is no longer one element longer than requested by virtue of the acl[1] base pointer. This also avoids one of the few remaining cases of over-allocation of a structure. Andrew Bartlett

2012-07-11s3:vfs_gpfs: Check softquota before gracetimeChristof Schmitt1-1/+2
gpfs_quotactl can return a non-zero softquota gracetime even when no softquota has been set. This could lead to "disk full" being reported to a client. The easiest fix is to check for a valid softquota before checking the softquota gracetime.
2012-06-22s3-vfs_gpfs: Fix bug #9003, posix acl on gpfsVolker Lendecke1-2/+2
gpfs2smb_acl can leave errno!=0 around even if it returned a correct result!=NULL. We can only rely on errno being set if another error condition (in this case result==NULL) indicates an error. If result!=NULL, errno is undefined and can be anything. This leads to SAFE_FREE(result) further down even in the success case.

2012-03-22s3:vfs_gpfs: Report disk space and usage on GPFS share according to quotasChristof Schmitt1-0/+129
When a client requests the information about free space and space used, adjust the reported values according to quotas in the GPFS file system: - Retrieve quotas for the current user, current group and fileset for the top level of the share. - If the soft block quota grace time has expired, report disk as full. - If a hard block quota has been exceeded, report disk as full. - If none of the hard block quotas been exceeded, report share size and free space according to the lowest limits found in the quotas. - If no applicable hard block quota has been set, report the information from the statfs call. This feature is disabled by default and has to be enabled by setting the option gpfs:dfreequota.

2012-02-10s3:vfs_gpfs:Fix query of creation time from GPFSChristof Schmitt1-0/+3
Setting the creation time through SetFileTime on a GPFS file system and querying it with GetFileTime shows a mismatch. The vfs_gpfs module first retrieves the information from the operating system and the flag st_ex_calculated_birthtime is set to false. When vfs_gpfs retrieves the birthtime from GPFS the flag st_ex_calculated_birthtime has to be set to true. Otherwise the birth time will get overwritten by a call to update_stat_ex_mtime, reporting the wrong time to a client system. Signed-off-by: Christian Ambach <ambi@samba.org>
