2011-03-21bfs: fix bitmap size argument to find_first_zero_bit()Akinobu Mita1-1/+1
The usage of find_first_zero_bit() in bfs_create() is wrong for two reasons. The bitmap size argument to find_first_zero_bit() is info->si_lasti but the correct bitmap size is info->si_lasti + 1 as info->si_lasti is the last valid index in info->si_imap bitmap. Another problem is that it is impossible to detect that info->si_imap bitmap is full because there is an off-by-one bug in the return value check for find_first_zero_bit(). If no zero bits exist in info->si_imap, find_first_zero_bit() returns info->si_lasti. But the check can't catch it due to the off-by-one.

2011-03-21introduce sys_syncfs to sync a single file systemSage Weil7-2/+34
It is frequently useful to sync a single file system, instead of all mounted file systems via sync(2): - On machines with many mounts, it is not at all uncommon for some of them to hang (e.g. unresponsive NFS server). sync(2) will get stuck on those and may never get to the one you do care about (e.g., /). - Some applications write lots of data to the file system and then want to make sure it is flushed to disk. Calling fsync(2) on each file introduces unnecessary ordering constraints that result in a large amount of sub-optimal writeback/flush/commit behavior by the file system. There are currently two ways (that I know of) to sync a single super_block: - BLKFLSBUF ioctl on the block device: That also invalidates the bdev mapping, which isn't usually desirable, and doesn't work for non-block file systems. - 'mount -o remount,rw' will call sync_filesystem as an artifact of the current implemention. Relying on this little-known side effect for something like data safety sounds foolish. Both of these approaches require root privileges, which some applications do not have (nor should they need?) given that sync(2) is an unprivileged operation. This patch introduces a new system call syncfs(2) that takes an fd and syncs only the file system it references. Maybe someday we can $ sync /some/path and not get sync: ignoring all arguments The syscall is motivated by comments by Al and Christoph at the last LSF. syncfs(2) seems like an appropriate name given statfs(2). A similar ioctl was also proposed a while back, see http://marc.info/?l=linux-fsdevel&m=127970513829285&w=2 Signed-off-by: Sage Weil <[email protected]> Signed-off-by: Al Viro <[email protected]>

2011-03-21powerpc/ptrace: Remove BUG_ON when full register set not availableMike Wolf2-3/+14
In some cases during a threaded core dump not all the threads will have a full register set. This happens when the signal causing the core dump races with a thread exiting. The race happens when the exiting thread has entered the kernel for the last time before the signal arrives, but doesn't get far enough through the exit code to avoid being included in the core dump. So we get a thread included in the core dump which is never going to go out to userspace again and only has a partial register set recorded Normally we would catch each thread as it is about to go into userspace and capture the full register set then. However, this exiting thread is never going to go out to userspace again, so we have no way to capture its full register set. It doesn't really matter, though, as this is a thread which is effectively already dead. So instead of hitting a BUG() in this case (a really bad choice of action in the first place), we use a poison value for the register values.

2011-03-21powerpc: Make MPIC honor the "pic-no-reset" device tree propertyMeador Inge2-11/+59
This property, defined in the Open PIC binding, tells the kernel not to use the reset bit in the global configuration register. Additionally, its presence mandates that only sources which are actually used (i.e. appear in the device tree) should have their VECPRI bits initialized. Although, "pic-no-reset" can be used for the same use cases that "protected-sources" is covering, the "protected-sources" implementation was left completely intact. This is a more pragmatic approach as there are already several existing systems which use protected sources. If "pic-no-reset" *and* "protected-sources" are both used, however, then "pic-no-reset" takes precedence in terms of the init behavior and the sanity checks done by protected sources will still take place.

2011-03-21powerpc: Document the Open PIC device tree bindingMeador Inge1-0/+98
This binding documents several properties that have been in use for quite some time, and adds one new property 'pic-no-reset', which controls the runtime initialization behavior of the PIC. More specifically, the presence of 'pic-no-reset' mandates that the PIC shall not be reset during runtime initialization and that any initialization related to interrupt sources shall be limited to sources explicitly referenced in the device tree. This functionality is useful in AMP systems where multiple OSes are sharing the PIC and the reinitialization of the PIC can interfere with OSes that are already up and running. The interrupt specifier definition is based off of Stuart Yoder's FSL MPIC binding.

Commit b5d937de0367d26f65b9af1aef5f2c34c1939be0 has a bug which causes basically a NULL dereference in the PCI code during boot on ppc64 machines. fetch_dev_dn() is called when dev->dev.of_node is NULL, so using that as the starting point for the search makes no sense.
