2011-05-25mmc: remove redundant irq disablingJohn Ogness1-8/+0
There is no need to disable irq's when using the sg_copy_*_buffer() functions because those functions do that already. There are also no races for the mm_queue struct here that would require the irq's to be disabled before calling sg_copy_*_buffer().

2011-05-16drm: Take lock around probes for drm_fb_helper_hotplug_eventChris Wilson2-5/+23
We need to hold the dev->mode_config.mutex whilst detecting the output status. But we also need to drop it for the call into drm_fb_helper_single_fb_probe(), which indirectly acquires the lock when attaching the fbcon. Failure to do so exposes a race with normal output probing. Detected by adding some warnings that the mutex is held to the backend detect routines: [ 17.772456] WARNING: at drivers/gpu/drm/i915/intel_crt.c:471 intel_crt_detect+0x3e/0x373 [i915]() [ 17.772458] Hardware name: Latitude E6400 [ 17.772460] Modules linked in: ....

If the requested device is already active, ignore the request. This restores the original behaviour of the interface. The change was probably an unintended side effect of commit 66b37c6777c4 vga_switcheroo: split switching into two stages which did not take into account to duplicate the !active check in the split-off stage2. Fix this by factoring that check out of stage1 into the debugfs_write routine.

FS_COW_FL and FS_NOCOW_FL were newly introduced to control per file COW in btrfs, but FS_NOCOW_FL is sufficient. The fact is we don't have corresponding BTRFS_INODE_COW flag. COW is default, and FS_NOCOW_FL can be used to switch off COW for a single file. If we mount btrfs with nodatacow, a newly created file will be set with the FS_NOCOW_FL flag. So to turn on COW for it, we can just clear the FS_NOCOW_FL flag. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>

When a btrfs disk is created by mixed data & metadata option, it will have no pure data or pure metadata space info. In btrfs's for-linus branch, commit 78b1ea13838039cd88afdd62519b40b344d6c920 (Btrfs: fix OOPS of empty filesystem after balance) initializes space infos at the very beginning. The problem is this initialization does not take the mixed case into account, which will cause btrfs will easily get into ENOSPC in mixed case.

2011-05-14tmpfs: fix race between swapoff and writepageHugh Dickins1-6/+4
Shame on me! Commit b1dea800ac39 "tmpfs: fix race between umount and writepage" fixed the advertized race, but introduced another: as even its comment makes clear, we cannot safely rely on a peek at list_empty() while holding no lock - until info->swapped is set, shmem_unuse_inode() may delete any formerly-swapped inode from the shmem_swaplist, which in this case would leave a swap area impossible to swapoff. Although I don't relish taking the mutex every time, I don't care much for the alternatives either; and at least the peek at list_empty() in shmem_evict_inode() (a hotter path since most inodes would never have been swapped) remains safe, because we already truncated the whole file.

This moves the if (num_registered_fb == FB_MAX) return -ENXIO; check _AFTER_ the call to do_remove_conflicting_framebuffers() as this would (now in a safe way) allow a native driver to replace the conflicting one even if all slots in registered_fb[] are taken. This also prevents unregistering a framebuffer that is no longer registered (vga16f will unregister at module unload time even if the frame buffer had been unregistered earlier due to being found conflicting).

2011-05-14fbmem: fix remove_conflicting_framebuffers racesLinus Torvalds1-49/+68
When a register_framebuffer() call results in us removing old conflicting framebuffers, the new registration_lock doesn't protect that situation. And we can't just add the same locking to the function, because these functions call each other: register_framebuffer() calls remove_conflicting_framebuffers, which in turn calls unregister_framebuffer for any conflicting entry. In order to fix it, this just creates wrapper functions around all three functions and makes the versions that actually do the work be called "do_xxx()", leaving just the wrapper that gets the lock and calls the worker function. So the rule becomes simply that "do_xxxx()" has to be called with the lock held, and now do_register_framebuffer() can just call do_remove_conflicting_framebuffers(), and that in turn can call _do_unregister_framebuffer(), and there is no deadlock, and we can hold the registration lock over the whole sequence, fixing the races. It also makes error cases simpler, and fixes one situation where we would return from unregister_framebuffer() without releasing the lock, pointed out by Bruno Prémont.

2011-05-14rbd: fix split bio handlingYehuda Sadeh1-20/+151
The rbd driver currently splits bios when they span an object boundary. However, the blk_end_request expects the completions to roll up the results in block device order, and the split rbd/ceph ops can complete in any order. This patch adds a struct rbd_req_coll to track completion of split requests and ensures that the results are passed back up to the block layer in order. This fixes errors where the file system gets completion of a read operation that spans an object boundary before the data has actually arrived. The bug is easily reproduced with iozone with a working set larger than available RAM.

2011-05-13ipv6: restore correct ECN handling on TCP xmitSteinar H. Gunderson1-3/+13
Since commit e9df2e8fd8fbc9 (Use appropriate sock tclass setting for routing lookup) we lost ability to properly add ECN codemarks to ipv6 TCP frames. It seems like TCP_ECN_send() calls INET_ECN_xmit(), which only sets the ECN bit in the IPv4 ToS field (inet_sk(sk)->tos), but after the patch, what's checked is inet6_sk(sk)->tclass, which is a completely different field. Close bug https://bugzilla.kernel.org/show_bug.cgi?id=34322 [Eric Dumazet] : added the INET_ECN_dontxmit() fix and replace macros by inline functions for clarity. Signed-off-by: Steinar H.

2011-05-13vsprintf: Turn kptr_restrict off by defaultIngo Molnar1-1/+1
kptr_restrict has been triggering bugs in apps such as perf, and it also makes the system less useful by default, so turn it off by default. This is how we generally handle security features that remove functionality, such as firewall code or SELinux - they have to be configured and activated from user-space. Distributions can turn kptr_restrict on again via this line in /etc/sysctrl.conf: kernel.kptr_restrict = 1 ( Also mark the variable __read_mostly while at it, as it's typically modified only once per bootup, or not at all. ) Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: David S.

2011-05-13net/9p/protocol.c: Fix a memory leakPedro Scarapicchia Junior1-0/+1
When p9pdu_readf() is called with "s" attribute, it allocates a pointer that will store a string. In p9dirent_read(), this pointer is not being released, leading to out of memory errors. This patch releases this pointer after string is copyed to dirent->d_name.

2011-05-13ne-h8300: Fix regression caused during net_device_ops conversionGeert Uytterhoeven2-9/+9
Changeset dcd39c90290297f6e6ed8a04bb20da7ac2b043c5 ("ne-h8300: convert to net_device_ops") broke ne-h8300 by adding 8390.o to the link. That meant that lib8390.c was included twice, once in ne-h8300.c and once in 8390.c, subject to different macros. This patch reverts that by avoiding the wrappers in 8390.c. Fix based on commits 217cbfa856dc1cbc2890781626c4032d9e3ec59f ("mac8390: fix regression caused during net_device_ops conversion") and 4e0168fa4842e27795a75b205a510f25b62181d9 ("mac8390: fix build with NET_POLL_CONTROLLER").
