2013-09-06Squashfs: fix corruption checks in squashfs_lookup()Phillip Lougher
The dir_count and size fields when read from disk are sanity checked for correctness. However, the sanity checks only check the values are not greater than expected. As dir_count and size were incorrectly defined as signed ints, this can lead to corrupted values appearing as negative which are not trapped. Signed-off-by: Phillip Lougher <phillip@squashfs.org.uk>
2013-09-06Squashfs: fix corruption check in get_dir_index_using_name()Phillip Lougher
Patch "Squashfs: sanity check information from disk" from Dan Carpenter adds a missing check for corruption in the "size" field while reading the directory index from disk. It, however, sets err to -EINVAL, this value is not used later, and so setting it is completely redundant. So remove it. Errors in reading the index are deliberately non-fatal. If we get an error in reading the index we just return the part of the index we have managed to read - the index isn't essential, just quicker.

2013-09-05dm: add statistics supportMikulas Patocka
Support the collection of I/O statistics on user-defined regions of a DM device. If no regions are defined no statistics are collected so there isn't any performance impact. Only bio-based DM devices are currently supported. Each user-defined region specifies a starting sector, length and step. Individual statistics will be collected for each step-sized area within the range specified. The I/O statistics counters for each step-sized area of a region are in the same format as /sys/block/*/stat or /proc/diskstats but extra counters (12 and 13) are provided: total time spent reading and writing in milliseconds. All these counters may be accessed by sending the @stats_print message to the appropriate DM device via dmsetup. The creation of DM statistics will allocate memory via kmalloc or fallback to using vmalloc space. At most, 1/4 of the overall system memory may be allocated by DM statistics. The admin can see how much memory is used by reading /sys/module/dm_mod/parameters/stats_current_allocated_bytes See Documentation/device-mapper/statistics.txt for more details.

2013-09-05dm thin: always return -ENOSPC if no_free_space is setMike Snitzer
If pool has 'no_free_space' set it means a previous allocation already determined the pool has no free space (and failed that allocation with -ENOSPC). By always returning -ENOSPC if 'no_free_space' is set, we do not allow the pool to oscillate between allocating blocks and then not. But a side-effect of this determinism is that if a user wants to be able to allocate new blocks they'll need to reload the pool's table (to clear the 'no_free_space' flag). This reload will happen automatically if the pool's data volume is resized. But if the user takes action to free a lot of space by deleting snapshot volumes, etc the pool will no longer allow data allocations to continue without an intervening table reload.

2013-09-05dm ioctl: increase granularity of type_lock when loading tableMike Snitzer
Hold the mapped device's type_lock before calling populate_table() since it is where the table's type is determined based on the specified targets. There is no need to allow concurrent table loads to race to establish the table's targets or type. This eliminates the need to grab the lock in dm_table_set_type(). Also verify that the type_lock is held in both dm_set_md_type() and dm_get_md_type(). Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2013-09-05dm ioctl: prevent rename to empty name or uuidAlasdair Kergon
A device-mapper device must always have a name consisting of a non-empty string. If the device also has a uuid, this similarly must not be an empty string. The DM_DEV_CREATE ioctl enforces these rules when the device is created, but this patch is needed to enforce them when DM_DEV_RENAME is used to change the name or uuid.

2013-09-05dm: allow error target to replace bio-based and request-based targetsMike Snitzer
It may be useful to switch a request-based table to the "error" target. Enhance the DM core to allow a hybrid target_type which is capable of handling either bios (via .map) or requests (via .map_rq). Add a request-based map function (.map_rq) to the "error" target_type; making it DM's first hybrid target. Train dm_table_set_type() to prefer the mapped device's established type (request-based or bio-based). If the mapped device doesn't have an established type default to making the table with the hybrid target(s) bio-based. Tested 'dmsetup wipe_table' to work on both bio-based and request-based devices.

2013-09-05fuse: use d_materialise_unique()Miklos Szeredi
Use d_materialise_unique() instead of d_splice_alias(). This allows dentry subtrees to be moved to a new place if there moved, even if something is referencing a dentry in the subtree (open fd, cwd, etc..). This will also allow us to drop a subtree if it is found to be replaced by something else. In this case the disconnected subtree can later be reconnected to its new location. d_materialise_unique() ensures that a directory entry only ever has one alias. We keep fc->inst_mutex around the calls for d_materialise_unique() on directories to prevent a race with mkdir "stealing" the inode.

2013-09-05vfs: check unlinked ancestors before mountMiklos Szeredi
We check submounts before doing d_drop() on a non-empty directory dentry in NFS (have_submounts()), but we do not exclude a racing mount. Nor do we prevent mounts to be added to the disconnected subtree using relative paths after the d_drop(). This patch fixes these issues by checking for unlinked (unhashed, non-root) ancestors before proceeding with the mount. This is done with rename seqlock taken for write and with ->d_lock grabbed on each ancestor in turn, including our dentry itself. This ensures that the only one of check_submounts_and_drop() or has_unlinked_ancestor() can succeed. Signed-off-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Conflicts: drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c net/bridge/br_multicast.c net/ipv6/sit.c The conflicts were minor: 1) sit.c changes overlap with change to ip_tunnel_xmit() signature. 2) br_multicast.c had an overlap between computing max_delay using msecs_to_jiffies and turning MLDV2_MRC() into an inline function with a name using lowercase instead of uppercase letters. 3) stmmac had two overlapping changes, one which conditionally allocated and hooked up a dma_cfg based upon the presence of the pbl OF property, and another one handling store-and-forward DMA made. The latter of which should not go into the new of_find_property() basic block. Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "This series contains: - Exynos s5p-mfc driver got support for VP8 encoder - Some SoC drivers gained support for asynchronous registration (needed for DT) - The RC subsystem gained support for RC activity LED; - New drivers added: a video decoder(adv7842), a video encoder (adv7511), a new GSPCA driver (stk1135) and support for Renesas R-Car (vsp1) - the first SDR kernel driver: mirics msi3101. Due to some troubles with the driver, and because the API is still under discussion, it will be merged at staging for 3.12.

As reported by Randy Dunlap: ==================== when CONFIG_IPV6=m and CONFIG_NETFILTER_XT_MATCH_SOCKET=y: net/built-in.o: In function `socket_mt6_v1_v2': xt_socket.c:(.text+0x51b55): undefined reference to `udp6_lib_lookup' net/built-in.o: In function `socket_mt_init': xt_socket.c:(.init.text+0x1ef8): undefined reference to `nf_defrag_ipv6_enable' ==================== Like several other modules under net/netfilter/ we have to have a dependency "IPV6 disabled or set compatibly with this module" clause.

2013-09-05vxlan: Fix kernel panic on device delete.Pravin B Shelar
On vxlan device create if socket create fails vxlan device is not added to hash table. Therefore we need to check if device is in hashtable before we delete it from hlist. Following patch avoid the crash. net-next already has this fix. ---8<--- BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffffa05f9ca7>] vxlan_dellink+0x77/0xf0 [vxlan] PGD 42b2d9067 PUD 42e04c067 PMD 0 Oops: 0002 [#1] SMP Modules linked in: vxlan(-) Hardware name: Dell Inc.
