| * [CVE-2009-0029] System call wrapper special casesHeiko Carstens2009-01-14
| | | | | | | | | | | | | | | | | | | | | | | | System calls with an unsigned long long argument can't be converted with the standard wrappers since that would include a cast to long, which in turn means that we would lose the upper 32 bit on 32 bit architectures. Also semctl can't use the standard wrapper since it has a 'union' parameter. So we handle them as special case and add some extra wrappers instead.

| * Fix timeouts in sys_pselect7Bernd Schmidt2009-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we (Analog Devices) updated our Blackfin kernel to 2.6.28, we've seen occasional 5-second hangs from telnet. telnetd calls select with a NULL timeout, but with the new kernel, the system call occasionally returns 0, which causes telnet to call sleep (5). This did not happen with earlier kernels. The code in sys_pselect7 looks a bit strange, in particular the variable "to" is initialized to NULL, then changed if a non-null timeout was passed in, but not used further. It needs to be passed to core_sys_select instead of &end_time. This bug was introduced by 8ff3e8e85fa6c312051134b3953e397feb639f51 ("select: switch select() and poll() over to hrtimers").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code would leak iterators and leave reference counts on rsbs because it was ignoring the "stop" seq callback. The code followed an example that used the seq operations differently. This new code is based on actually understanding how the seq operations work. It also improves things by saving the hash bucket in the position to avoid cycling through completed buckets in start. Siged-off-by: Davd Teigland <teigland@redhat.com>

| * | filesystem freeze: add error handling of write_super_lockfs/unlockfsTakashi Sato2009-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ext3 in mainline Linux doesn't have the freeze feature which suspends write requests. So, we cannot take a backup which keeps the filesystem's consistency with the storage device's features (snapshot and replication) while it is mounted. In many case, a commercial filesystem (e.g. VxFS) has the freeze feature and it would be used to get the consistent backup. If Linux's standard filesystem ext3 has the freeze feature, we can do it without a commercial filesystem. So I have implemented the ioctls of the freeze feature. I think we can take the consistent backup with the following steps. 1. Freeze the filesystem with the freeze ioctl. 2. Separate the replication volume or create the snapshot with the storage device's feature. 3. Unfreeze the filesystem with the unfreeze ioctl. 4. Take the backup from the separated replication volume or the snapshot. This patch: VFS: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they can return an error. Rename write_super_lockfs and unlockfs of the super block operation freeze_fs and unfreeze_fs to avoid a confusion. ext3, ext4, xfs, gfs2, jfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that write_super_lockfs returns an error if needed, and unlockfs always returns 0. reiserfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they always return 0 (success) to keep a current behavior.
