2010-02-08V4L/DVB: Fix the risk of an oops at dvb_dmx_releaseMauro Carvalho Chehab
dvb_dmx_init tries to allocate virtual memory for 2 pointers: filter and feed. If the second vmalloc fails, filter is freed, but the pointer keeps pointing to the old place. Later, when dvb_dmx_release() is called, it will try to free an already freed memory, causing an OOPS.

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.

2010-02-07ima: initialize ima before inodes can be allocatedEric Paris
ima wants to create an inode information struct (iint) when inodes are allocated. This means that at least the part of ima which does this allocation (the allocation is filled with information later) should before any inodes are created. To accomplish this we split the ima initialization routine placing the kmem cache allocator inside a security_initcall() function. Since this makes use of radix trees we also need to make sure that is initialized before security_initcall().

2010-02-07fix ima breakageMimi Zohar
The "Untangling ima mess, part 2 with counters" patch messed up the counters. Based on conversations with Al Viro, this patch streamlines ima_path_check() by removing the counter maintaince. The counters are now updated independently, from measuring the file, in __dentry_open() and alloc_file() by calling ima_counts_get(). ima_path_check() is called from nfsd and do_filp_open(). It also did not measure all files that should have been measured. Reason: ima_path_check() got bogus value passed as mask.

2010-02-07freeze_bdev: don't deactivate successfully frozen MS_RDONLY sbJun'ichi Nomura
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. Otherwise a crash reported here can happen: http://lkml.org/lkml/2010/1/16/37 http://lkml.org/lkml/2010/1/28/53 This patch should be applied for 2.6.32 stable series, too.

2010-02-05hwmon: (w83781d) Request I/O ports individually for probingJean Delvare
Different motherboards have different PNP declarations for W83781D/W83782D chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

As anticipated, we've run into a buggy BIOS: [ 0.081818] pci 0000:00:14.0: reg 10: [io 0x6000-0x7fff] [ 0.081906] pci 0000:00:14.0: reg 14: [io 0x6100-0x61ff] [ 0.082015] pci 0000:00:14.0: reg 18: [io 0x6200-0x63ff] [ 0.082917] pci 0000:00:14.2: reg 20: [io 0xe000-0xe00f] [ 0.083551] pci 0000:00:15.0: reg 10: [mem 0xa0010000-0xa0010fff] [ 0.084436] pci 0000:00:15.1: reg 10: [mem 0xa0011000-0xa0011fff] [ 0.088816] PCI: pci_cache_line_size set to 32 bytes [ 0.088938] pci 0000:00:14.0: address space collision: [io 0x6100-0x61ff] already in use [ 0.089052] pci 0000:00:14.0: can't reserve [io 0x6100-0x61ff] This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge device's BAR0 to 8k. In reality, it should be 8 bytes (BAR0 is used for SMBus stuff). This quirk checks for an incorrect size, and resets it accordingly.
