* Server backend storage hang should not cause the mount point to hang.Anand Avati2010-01-234-6/+158
| | | | | | | | | | | | | | | | | | | Submitted-by: Krishna Srinivas <krishna@gluster.com> NOTE: fixed compilation issues in posix.c introduced while merging storage/posix polls for FS/kernel being functional by issuing statvfs() call. In case statvfs expires the timer, storage/posix will send CHILD_DOWN to upper translator. Ultimately this will cause protocol/server to disconnect all clients connected and also cleans up the data structures. Hence if soft lockup or other kernel bug causes backend FS to hang, the clients will not be hung. Signed-off-by: Krishna Srinivas <krishna@gluster.com> Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | | | | Support for auxiliary group ids is needed for transmission of more than one group id right through the xlator tree so that posix can use these group ids to perform in-house permission tests. The in-house permission checks are needed so that we do not have to depend on non-POSIX calls like setfs[ug]id for changing the user for each fop. The setfs[ug]id are also limited since they do not allow setting multiple group id as required for operation with NFS, which sends us all the group ids for a process issuing file system requests.
