2013-01-14vfs: add missing virtual cache flush after editing partial pagesLinus Torvalds1-0/+1
Andrew Morton pointed this out a month ago, and then I completely forgot about it. If we read a partial last page of a block device, we will zero out the end of the page, but since that page can then be mapped into user space, we should also make sure to flush the cache on architectures that have virtual caches. We have the flush_dcache_page() function for this, so use it. Now, in practice this really never matters, because nobody sane uses virtual caches to begin with, and they largely exist on old broken RISC arhitectures. And even if you did run on one of those obsolete CPU's, the whole "mmap and access the last partial page of a block device" behavior probably doesn't actually exist. The normal IO functions (read/write) will never see the zeroed-out part of the page that migth not be coherent in the cache, because they honor the size of the device. So I'm marking this for stable (3.7 only), but I'm not sure anybody will ever care.

2013-01-14btrfs: update timestamps on truncate()Eric Sandeen1-3/+14

2013-01-14btrfs: fix btrfs_cont_expand() freeing IS_ERR emZach Brown1-0/+1
btrfs_cont_expand() tries to free an IS_ERR em as it gets an error from btrfs_get_extent() and breaks out of its loop. An instance of -EEXIST was reported in the wild: https://bugzilla.redhat.com/show_bug.cgi?id=874407 I have no idea if that -EEXIST is surprising, or not. Regardless, this error handling should be cleaned up to handle other reasonable errors (ENOMEM, EIO; whatever). This seemed to be the only buggy freeing of the relatively rare IS_ERR em so I opted to fix the caller rather than teach free_extent_map() to use IS_ERR_OR_NULL().

2013-01-14Btrfs: add orphan before truncating pagecacheJosef Bacik1-15/+38
Running xfstests 83 in a loop would sometimes fail the fsck. This happens because if we invalidate a page that already has an ordered extent setup for it we will complete the ordered extent ourselves, assuming that the truncate will clean everything up. The problem with this is there is plenty of time for the truncate to fail after we've done this work. So to fix this we need to add the orphan item first to make sure the cleanup gets done properly, and then we can truncate the pagecache and all that stuff and be safe. This fixes the btrfsck failures I was seeing while running 83 in a loop. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

2013-01-11fs/exec.c: work around icc miscompilationXi Wang1-1/+2
The tricky problem is this check: if (i++ >= max) icc (mis)optimizes this check as: if (++i > max) The check now becomes a no-op since max is MAX_ARG_STRINGS (0x7FFFFFFF). This is "allowed" by the C standard, assuming i++ never overflows, because signed integer overflow is undefined behavior. This optimization effectively reverts the previous commit 362e6663ef23 ("exec.c, compat.c: fix count(), compat_count() bounds checking") that tries to fix the check. This patch simply moves ++ after the check.

2013-01-11f2fs: add f2fs_balance_fs in several interfacesJaegeuk Kim4-0/+10
The f2fs_balance_fs() is to check the number of free sections and decide whether it needs to conduct cleaning or not. If there are not enough free sections, the cleaning job should be started. In order to control an amount of free sections even under high utilization, f2fs should call f2fs_balance_fs at all the VFS interfaces that are able to produce dirty pages. This patch adds the function calls in the missing interfaces as follows. 1. f2fs_setxattr() The f2fs_setxattr() produces dirty node pages so that we should call f2fs_balance_fs() either likewise doing in other VFS interfaces such as f2fs_lookup(), f2fs_mkdir(), and so on. 2. f2fs_sync_file() We should guarantee serving free sections for syncing metadata during fsync. Previously, there is no space check before triggering checkpoint and sync_node_pages. Therefore, if a bunch of fsync calls are triggered under 100% of FS utilization, f2fs is able to be faced with no free sections, resulting in BUG_ON(). 3. f2fs_sync_fs() Before calling write_checkpoint(), we should guarantee that there are minimum free sections. 4. f2fs_write_inode() f2fs_write_inode() is also able to produce dirty node pages.

2013-01-06tcp: fix MSG_SENDPAGE_NOTLAST logicEric Dumazet1-1/+3
commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all frags but the last one for a splice() call. The condition used to set the flag in pipe_to_sendpage() relied on splice() user passing the exact number of bytes present in the pipe, or a smaller one. But some programs pass an arbitrary high value, and the test fails. The effect of this bug is a lack of tcp_push() at the end of a splice(pipe -> socket) call, and possibly very slow or erratic TCP sessions. We should both test sd->total_len and fact that another fragment is in the pipe (pipe->nrbufs > 1) Many thanks to Willy for providing very clear bug report, bisection and test programs.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit from the pstore filesystem. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2013-01-03NFS: Fix access to suid/sgid executablesWeston Andros Adamson2-13/+21
nfs_open_permission_mask() should only check MAY_EXEC for files that are opened with __FMODE_EXEC. Also fix NFSv4 access-in-open path in a similar way -- openflags must be used because fmode will not always have FMODE_EXEC set.

Pull GFS2 fixes from Steven Whitehouse: "Here are four small bug fixes for GFS2. There is no common theme here really, just a few items that were fixed recently. The first fixes lock name generation when the glock number is 0. The second fixes a race allocating reservation structures and the final two fix a performance issue by making small changes in the allocation code." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes: GFS2: Reset rd_last_alloc when it reaches the end of the rgrp GFS2: Stop looking for free blocks at end of rgrp GFS2: Fix race in gfs2_rs_alloc GFS2: Initialize hex string to '0'
