2013-01-24Btrfs: do not allow logged extents to be merged or removedJosef Bacik3-3/+16
We drop the extent map tree lock while we're logging extents, so somebody could come in and merge another extent into this one and screw up our logging, or they could even remove us from the list which would keep us from logging the extent or freeing our ref on it, so we need to make sure to not clear LOGGING until after the extent is logged, and then we can merge it to adjacent extents. Thanks, Signed-off-by: Josef Bacik <[email protected]>
2013-01-24x86/msr: Add capabilities checkAlan Cox1-0/+3
At the moment the MSR driver only relies upon file system checks. This means that anything as root with any capability set can write to MSRs. Historically that wasn't very interesting but on modern processors the MSRs are such that writing to them provides several ways to execute arbitary code in kernel space. Sample code and documentation on doing this is circulating and MSR attacks are used on Windows 64bit rootkits already. In the Linux case you still need to be able to open the device file so the impact is fairly limited and reduces the security of some capability and security model based systems down towards that of a generic "root owns the box" setup. Therefore they should require CAP_SYS_RAWIO to prevent an elevation of capabilities. The impact of this is fairly minimal on most setups because they don't have heavy use of capabilities. Those using SELinux, SMACK or AppArmor rules might want to consider if their rulesets on the MSR driver could be tighter.

2013-01-24DM-RAID: Fix RAID10's check for sufficient redundancyJonathan Brassow2-64/+38
Before attempting to activate a RAID array, it is checked for sufficient redundancy. That is, we make sure that there are not too many failed devices - or devices specified for rebuild - to undermine our ability to activate the array. The current code performs this check twice - once to ensure there were not too many devices specified for rebuild by the user ('validate_rebuild_devices') and again after possibly experiencing a failure to read the superblock ('analyse_superblocks'). Neither of these checks are sufficient. The first check is done properly but with insufficient information about the possible failure state of the devices to make a good determination if the array can be activated. The second check is simply done wrong in the case of RAID10 because it doesn't account for the independence of the stripes (i.e. mirror sets). The solution is to use the properly written check ('validate_rebuild_devices'), but perform the check after the superblocks have been read and we know which devices have failed. This gives us one check instead of two and performs it in a location where it can be done right. Only RAID10 was affected and it was affected in the following ways: - the code did not properly catch the condition where a user specified a device for rebuild that already had a failed device in the same mirror set. (This condition would, however, be caught at a deeper level in MD.) - the code triggers a false positive and denies activation when devices in independent mirror sets have failed - counting the failures as though they were all in the same set. The most likely place this error was introduced (or this patch should have been included) is in commit 4ec1e369 - first introduced in v3.7-rc1. Consequently this fix should also go in v3.7.y, however there is a small conflict on the .version in raid_target, so I'll submit a separate patch to -stable.

2013-01-23drm/radeon: fix a rare case of double kfreeIlija Hadzic1-0/+2
If one (but not both) allocations of p->chunks[].kpage[] in radeon_cs_parser_init fail, the error path will free the successfully allocated page, but leave a stale pointer value in the kpage[] field. This will later cause a double-free when radeon_cs_parser_fini is called. This patch fixes the issue by forcing both pointers to NULL after kfree in the error path. The circumstances under which the problem happens are very rare. The card must be AGP and the system must run out of kmalloc area just at the right time so that one allocation succeeds, while the other fails.

2013-01-23r8169: remove the obsolete and incorrect AMD workaroundTimo Teräs1-7/+0
This was introduced in commit 6dccd16 "r8169: merge with version 6.001.00 of Realtek's r8169 driver". I did not find the version 6.001.00 online, but in 6.002.00 or any later r8169 from Realtek this hunk is no longer present. Also commit 05af214 "r8169: fix Ethernet Hangup for RTL8110SC rev d" claims to have fixed this issue otherwise. The magic compare mask of 0xfffe000 is dubious as it masks parts of the Reserved part, and parts of the VLAN tag. But this does not make much sense as the VLAN tag parts are perfectly valid there. In matter of fact this seems to be triggered with any VLAN tagged packet as RxVlanTag bit is matched. I would suspect 0xfffe0000 was intended to test reserved part only. Finally, this hunk is evil as it can cause more packets to be handled than what was NAPI quota causing net/core/dev.c: net_rx_action(): WARN_ON_ONCE(work > weight) to trigger, and mess up the NAPI state causing device to hang. As result, any system using VLANs and having high receive traffic (so that NAPI poll budget limits rtl_rx) would result in device hang.

2013-01-23net: cdc_mbim: send ZLP only for the specific buggy deviceBjørn Mork1-0/+19
Reverting 328d7b8 and instead adding an exception for the Sierra Wireless MC7710. commit 328d7b8 (net: cdc_mbim: send ZLP after max sized NTBs) added a workaround for an issue observed on one specific device. Concerns were raised that this workaround adds a performance penalty to all devices based on questionable, if not buggy, behaviour of a single device: "If you add ZLP for NTBs of dwNtbOutMaxSize, you are heavily affecting CPU load, increasing interrupt load by factor of 2 in high load traffic scenario and possibly decreasing throughput for all other devices which behaves correctly." "The idea of NCM was to avoid extra ZLPs. If your transfer is exactly dwNtbOutMaxSize, it's known, you can submit such request on the receiver side and you do not need any EOT indicatation, so the frametime can be used for useful data." Adding a device specific exception to prevent the workaround from affecting well behaved devices. The assumption here is that needing a ZLP is truly an *exception*. We do not yet have enough data to verify this. The generic workaround in commit 328d7b8 should be considered acceptable despite the performance penalty if the exception list becomes a maintainance hassle.

2013-01-23ALSA: hda - Fix inconsistent pin states after resumeTakashi Iwai1-3/+2
The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a module parameter] introduced the polling jack detection code, but it also moved the call of snd_hda_jack_set_dirty_all() in the resume path after resume/init ops call. This caused a regression when the jack state has been changed during power-down (e.g. in the power save mode). Since the driver doesn't probe the new jack state but keeps using the cached value due to no dirty flag, the pin state remains also as if the jack is still plugged. The fix is simply moving snd_hda_jack_set_dirty_all() to the original position. Reported-by: Manolo Díaz <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>

2013-01-22fs/cifs/cifs_dfs_ref.c: fix potential memory leakageCong Ding1-0/+2
When it goes to error through line 144, the memory allocated to *devname is not freed, and the caller doesn't free it either in line 250. So we free the memroy of *devname in function cifs_compose_mount_options() when it goes to error.

2013-01-22Revert "drivers/misc/ti-st: remove gpio handling"Luciano Coelho1-1/+36
This reverts commit eccf2979b2c034b516e01b8a104c3739f7ef07d1. The reason is that it broke TI WiLink shared transport on Panda. Also, callback functions should not be added to board files anymore, so revert to implementing the power functions in the driver itself. Additionally, changed a variable name ('status' to 'err') so that this revert compiles properly.
