2010-02-13nilfs2: fix potential hang in nilfs_error on errors=remount-roRyusuke Konishi
nilfs_error() calls nilfs_detach_segment_constructor() if errors=remount-ro option is specified, and this may lead to a hang due to recursive locking of, for instance, nilfs->ns_segctor_sem and others. In this case, detaching segment constructor is not necessary because read-only flag is set to the filesystem and further writes are blocked. This fixes the potential hang issue by removing the nilfs_detach_segment_constructor() call from nilfs_error. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
2010-02-13nilfs2: use mnt_want_write in ioctls where write access is neededRyusuke Konishi
A few nilfs2 ioctls need to ask for and then later release write access to the mount in order to avoid potential write to read-only mounts. This adds the missing mnt_want_write and mnt_drop_write in nilfs_ioctl_change_cpmode, nilfs_ioctl_delete_checkpoint, and nilfs_ioctl_clean_segments.

2010-02-12xfs: optimize log flushing in xfs_fsyncChristoph Hellwig
If we have a pinned inode it must have a log item attached to it. Usually that log item will have ili_last_lsn already set, in which case we only need to flush the log up to that LSN instead of doing a full log force. This gives speedups of about 5% in some fsync heavy workloads. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
2010-02-12xfs: only clear the suid bit once in xfs_writeChristoph Hellwig

Note that xfs_write_clear_setuid issues a sync transaction while the path through ->setattr doesn't, but that is consistant with the other filesystems.

2010-02-12GFS2: Fix bmap allocation corner-case bugSteven Whitehouse
This patch solves a corner case during allocation which occurs if both metadata (indirect) and data blocks are required but there is an obstacle in the filesystem (e.g. a resource group header or another allocated block) such that when the allocation is requested only enough blocks for the metadata are returned. By changing the exit condition of this loop, we ensure that a minimum of one data block will always be returned. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2010-02-11fs/exec.c: restrict initial stack space expansion to rlimitMichael Neuling
When reserving stack space for a new process, make sure we're not attempting to expand the stack by more than rlimit allows. This fixes a bug caused by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") and unmasked by fc63cf237078c86214abcb2ee9926d8ad289da9b ("exec: setup_arg_pages() fails to return errors"). This bug means that when limiting the stack to less the 20*PAGE_SIZE (eg. 80K on 4K pages or 'ulimit -s 79') all processes will be killed before they start. This is particularly bad with 64K pages, where a ulimit below 1280K will kill every process. To test, do: 'ulimit -s 15; ls' before and after the patch is applied. Before it's applied, 'ls' should be killed. After the patch is applied, 'ls' should no longer be killed. A stack limit of 15KB since it's small enough to trigger 20*PAGE_SIZE. Also 15KB not a multiple of PAGE_SIZE, which is a trickier case to handle correctly with this code. 4K pages should be fine to test with.

2010-02-08Revert "nfsd4: fix error return when pseudoroot missing"J. Bruce Fields
Commit f39bde24b275ddc45d fixed the error return from PUTROOTFH in the case where there is no pseudofilesystem. This is really a case we shouldn't hit on a correctly configured server: in the absence of a root filehandle, there's no point accepting version 4 NFS rpc calls at all. But the shared responsibility between kernel and userspace here means the kernel on its own can't eliminate the possiblity of this happening. And we have indeed gotten this wrong in distro's, so new client-side mount code that attempts to negotiate v4 by default first has to work around this case. Therefore when commit f39bde24b275ddc45d arrived at roughly the same time as the new v4-default mount code, which explicitly checked only for the previous error, the result was previously fine mounts suddenly failing. We'll fix both sides for now: revert the error change, and make the client-side mount workaround more robust. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

2010-02-07Fix race in tty_fasync() properlyLinus Torvalds
This reverts commit 703625118069 ("tty: fix race in tty_fasync") and commit b04da8bfdfbb ("fnctl: f_modown should call write_lock_irqsave/ restore") that tried to fix up some of the fallout but was incomplete. It turns out that we really cannot hold 'tty->ctrl_lock' over calling __f_setown, because not only did that cause problems with interrupt disables (which the second commit fixed), it also causes a potential ABBA deadlock due to lock ordering. Thanks to Tetsuo Handa for following up on the issue, and running lockdep to show the problem. It goes roughly like this: - f_getown gets filp->f_owner.lock for reading without interrupts disabled, so an interrupt that happens while that lock is held can cause a lockdep chain from f_owner.lock -> sighand->siglock. - at the same time, the tty->ctrl_lock -> f_owner.lock chain that commit 703625118069 introduced, together with the pre-existing sighand->siglock -> tty->ctrl_lock chain means that we have a lock dependency the other way too. So instead of extending tty->ctrl_lock over the whole __f_setown() call, we now just take a reference to the 'pid' structure while holding the lock, and then release it after having done the __f_setown. That still guarantees that 'struct pid' won't go away from under us, which is all we really ever needed.

Thanks Thomas and Christoph for testing and review. I removed 'smp_wmb()' before up_write from the previous patch, since up_write() should have necessary ordering constraints. (I.e. the change of s_frozen is visible to others after up_write) I'm quite sure the change is harmless but if you are uncomfortable with Tested-by/Reviewed-by on the modified patch, please remove them. If MS_RDONLY, freeze_bdev should just up_write(s_umount) instead of deactivate_locked_super(). Also, keep sb->s_frozen consistent so that remount can check the frozen state.
