This reverts commit 274193224cdabd687d804a26e0150bb20f2dd52c. We have some problems related to selection of empty queues that need to be resolved, evidence so far points to the recursive merge logic making either being the cause or at least the accelerator for this.

Removing the parent of a watched file results in "kernel BUG at fs/notify/mark.c:139". To reproduce add "-w /tmp/audit/dir/watched_file" to audit.rules rm -rf /tmp/audit/dir This is caused by fsnotify_destroy_mark() being called without an extra reference taken by the caller.

2012-01-14dm: do not forward ioctls from logical volumes to the underlying devicePaolo Bonzini3-2/+27

2012-01-14block: fail SCSI passthrough ioctls on partition devicesPaolo Bonzini3-2/+55
Linux allows executing the SG_IO ioctl on a partition or LVM volume, and will pass the command to the underlying block device. This is well-known, but it is also a large security problem when (via Unix permissions, ACLs, SELinux or a combination thereof) a program or user needs to be granted access only to part of the disk. This patch lets partitions forward a small set of harmless ioctls; others are logged with printk so that we can see which ioctls are actually sent. In my tests only CDROM_GET_CAPABILITY actually occurred. Of course it was being sent to a (partition on a) hard disk, so it would have failed with ENOTTY and the patch isn't changing anything in practice. Still, I'm treating it specially to avoid spamming the logs. In principle, this restriction should include programs running with CAP_SYS_RAWIO. If for example I let a program access /dev/sda2 and /dev/sdb, it still should not be able to read/write outside the boundaries of /dev/sda2 independent of the capabilities. However, for now programs with CAP_SYS_RAWIO will still be allowed to send the ioctls. Their actions will still be logged. This patch does not affect the non-libata IDE driver. That driver however already tests for bd != bd->bd_contains before issuing some ioctl; it could be restricted further to forbid these ioctls even for programs running with CAP_SYS_ADMIN/CAP_SYS_RAWIO.

2012-01-13Unused iocbs in a batch should not be accounted as active.Gleb Natapov1-2/+9
Since commit 080d676de095 ("aio: allocate kiocbs in batches") iocbs are allocated in a batch during processing of first iocbs. All iocbs in a batch are automatically added to ctx->active_reqs list and accounted in ctx->reqs_active. If one (not the last one) of iocbs submitted by an user fails, further iocbs are not processed, but they are still present in ctx->active_reqs and accounted in ctx->reqs_active. This causes process to stuck in a D state in wait_for_all_aios() on exit since ctx->reqs_active will never go down to zero. Furthermore since kiocb_batch_free() frees iocb without removing it from active_reqs list the list become corrupted which may cause oops. Fix this by removing iocb from ctx->active_reqs and updating ctx->reqs_active in kiocb_batch_free().

Commit 8a25a2fd126c ("cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystem") changed how things are dealt with in the MCE subsystem. Some of the things that got broken due to this are CPU hotplug and suspend/hibernate. MCE uses per_cpu allocations of struct device. So, when a CPU goes offline and comes back online, in order to ensure that we start from a clean slate with respect to the MCE subsystem, zero out the entire per_cpu device structure to 0 before using it.

2012-01-13kconfig/streamline-config.pl: Fix parsing Makefile with variablesSteven Rostedt1-0/+29
Thomas Lange reported that when he did a 'make localmodconfig', his config was missing the brcmsmac driver, even though he had the module loaded. Looking into this, I found the file: drivers/net/wireless/brcm80211/brcmsmac/Makefile had the following in the Makefile: MODULEPFX := brcmsmac obj-$(CONFIG_BRCMSMAC) += $(MODULEPFX).o The way streamline-config.pl works, is parsing all the obj-$(CONFIG_FOO) += foo.o lines to find that CONFIG_FOO belongs to the module foo.ko. But in this case, the brcmsmac.o was not used, but a variable in its place. By changing streamline-config.pl to remember defined variables in Makefiles and substituting them when they are used in the obj-X lines, allows Thomas (and others) to have their brcmsmac module stay configured when it is loaded and running "make localmodconfig".

2012-01-13UBIFS: fix key printingArtem Bityutskiy6-88/+91
Before commit 56e46742e846e4de167dde0e1e1071ace1c882a5 we have had locking around all printing macros and we could use static buffers for creating key strings and printing them. However, now we do not have that locking and we cannot use static buffers. This commit removes the old DBGKEY() macros and introduces few new helper macros for printing debugging messages plus a key at the end. Thankfully, all the messages are already structures in a way that the key is printed in the end. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2012-01-13nouveau: Support Optimus models for vga_switcherooPeter Lekensteyn3-5/+42
Newer nVidia cards with Optimus do not support/use the DSM switching functions. Instead, it require a DSM function to be called prior to bringing a device into D3 state. No other _DSM calls are necessary before/after enabling/disabling a device. Switching between discrete and integrated GPU is not supported by this Optimus _DSM call, therefore return on the switching method.

[This fixes a crash on boot if the system is plugged into an HDTV so it's probably appropriate to push even though it didn't make the window.

To get around that issues we discard modes that doesn't fit. This is a temporary solution until we can freely allocate framebuffer memory.
