2012-03-31s3-aio-fork: Fix a segfault in vfs_aio_forkVolker Lendecke1-7/+9
aio_suspend does not signal the main process with a signal, it just waits. The aio_fork module does not use the signal at all, it directly calls back into the main smbd by calling smbd_aio_complete_aio_ex. This is an abstraction violation, but the alternative would have been to use signals where they are not needed. However, in wait_for_aio_completion this bites us: With aio_fork we call handle_aio_completed twice on the same aio_ex struct: Once from the call to handle_aio_completion within the aio_fork module and once from the code in wait_for_aio_completion. This patch fixes it in a pretty bad way by introducing flag variables and more state. But the mid-term plan is to replace the posix aio calls from the vfs and do pread_send/recv and pwrite_send/recv at the vfs layer, so this will significantly change anyway. Thanks to Kirill Malkin <kirill.malkin@starboardstorage.com> for reporting this crash! Autobuild-User: Volker Lendecke <vl@samba.org> Autobuild-Date: Sat Mar 31 15:25:55 CEST 2012 on sn-devel-104
2012-03-31s3-aio-fork: Fix aio_suspend event hierarchyVolker Lendecke1-10/+8
We end up here multiple times. There's no real point putting the events into the child struct, at the end of this routine we need to free them anyway.

2012-03-26s3: Pass filters explicitly through vfs notify watchVolker Lendecke4-11/+17
This removes a dependency on "struct notify_entry" and makes the nature of the API more explicit. We depend upon the VFS module to mask out elements from e->filter and e->subdir_filter that it took over to handle.

2012-03-24lib/util: Remove obsolete sys_getpid() and sys_fork().Jelmer Vernooij3-3/+3
The performance of these is minimal (these days) and they can return invalid results when used as part of applications that do not use sys_fork(). Autobuild-User: Jelmer Vernooij <jelmer@samba.org> Autobuild-Date: Sat Mar 24 21:55:41 CET 2012 on sn-devel-104

2012-03-22s3:vfs_gpfs: remove fallback to linux_setleaseChristian Ambach1-6/+0
if setting the lease in GPFS failed, there is not much sense in trying to set a lease just locally that would not inform us of openers on other cluster nodes
2012-03-22s3:vfs_gpfs: correct use of profiling macrosChristian Ambach1-4/+5

2012-03-22s3:vfs_gpfs: Implement fallocate callback for GPFSChristof Schmitt3-0/+54
GPFS provides the gpfs_prealloc call. Implement the fallocate callback with mode VFS_FALLOCATE_EXTEND_SIZE using this call. There is no support for VFS_FALLOCATE_KEEP_SIZE, so report this mode as not available.
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.
2012-03-22s3:vfs_gpfs: add GPFS api calls for quota and free space reportingChristof Schmitt2-0/+80
Add the GPFS api calls for reporting the quotas and free space: - get_gpfs_quota for querying a quota - get_gpfs_fset_id for mapping a path to a fileset id

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>

This will be used to enforce a lock hierarchy between the databases. We have seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb. These should be fixed by refusing a dbwrap_fetch_locked that does not follow a defined lock hierarchy.

2011-12-03Revert making public of the samba-module library.Jelmer Vernooij1-1/+1
This library was tiny - containing just two public functions than were themselves trivial. The amount of overhead this causes isn't really worth the benefits of sharing the code with other projects like OpenChange. In addition, this code isn't really generically useful anyway, as it can only load from the module path set for Samba at configure time. Adding a new library was breaking the API/ABI anyway, so OpenChange had to be updated to cope with the new situation one way or another. I've added a simpler (compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.
