2011-12-20binary_sysctl(): fix memory leakMichel Lespinasse
binary_sysctl() calls sysctl_getname() which allocates from names_cache slab usin __getname() The matching function to free the name is __putname(), and not putname() which should be used only to match getname() allocations. This is because when auditing is enabled, putname() calls audit_putname *instead* (not in addition) to __putname(). Then, if a syscall is in progress, audit_putname does not release the name - instead, it expects the name to get released when the syscall completes, but that will happen only if audit_getname() was called previously, i.e. if the name was allocated with getname() rather than the naked __getname(). So, __getname() followed by putname() ends up leaking memory.

2011-12-20oom: fix integer overflow of points in oom_badnessFrantisek Hrbata
An integer overflow will happen on 64bit archs if task's sum of rss, swapents and nr_ptes exceeds (2^31)/1000 value. This was introduced by commit f755a04 oom: use pte pages in OOM score where the oom score computation was divided into several steps and it's no longer computed as one expression in unsigned long(rss, swapents, nr_pte are unsigned long), where the result value assigned to points(int) is in range(1..1000). So there could be an int overflow while computing 176 points *= 1000; and points may have negative value. Meaning the oom score for a mem hog task will be one. 196 if (points <= 0) 197 return 1; For example: [ 3366] 0 3366 35390480 24303939 5 0 0 oom01 Out of memory: Kill process 3366 (oom01) score 1 or sacrifice child Here the oom1 process consumes more than 24303939(rss)*4096~=92GB physical memory, but it's oom score is one. In this situation the mem hog task is skipped and oom killer kills another and most probably innocent task with oom score greater than one. The points variable should be of type long instead of int to prevent the int overflow.

2011-12-20nilfs2: potential integer overflow in nilfs_ioctl_clean_segments()Haogang Chen
There is a potential integer overflow in nilfs_ioctl_clean_segments(). When a large argv[n].v_nmembs is passed from the userspace, the subsequent call to vmalloc() will allocate a buffer smaller than expected, which leads to out-of-bound access in nilfs_ioctl_move_blocks() and lfs_clean_segments(). The following check does not prevent the overflow because nsegs is also controlled by the userspace and could be very large. if (argv[n].v_nmembs > nsegs * nilfs->ns_blocks_per_segment) goto out_free; This patch clamps argv[n].v_nmembs to UINT_MAX / argv[n].v_size, and returns -EINVAL when overflow.

2011-12-20cpusets: stall when updating mems_allowed for mempolicy or disjoint nodemaskDavid Rientjes
Kernels where MAX_NUMNODES > BITS_PER_LONG may temporarily see an empty nodemask in a tsk's mempolicy if its previous nodemask is remapped onto a new set of allowed cpuset nodes where the two nodemasks, as a result of the remap, are now disjoint. c0ff7453bb5c ("cpuset,mm: fix no node to alloc memory when changing cpuset's mems") adds get_mems_allowed() to prevent the set of allowed nodes from changing for a thread. This causes any update to a set of allowed nodes to stall until put_mems_allowed() is called. This stall is unncessary, however, if at least one node remains unchanged in the update to the set of allowed nodes. This was addressed by 89e8a244b97e ("cpusets: avoid looping when storing to mems_allowed if one node remains set"), but it's still possible that an empty nodemask may be read from a mempolicy because the old nodemask may be remapped to the new nodemask during rebind. To prevent this, only avoid the stall if there is no mempolicy for the thread being changed. This is a temporary solution until all reads from mempolicy nodemasks can be guaranteed to not be empty without the get_mems_allowed() synchronization. Also moves the check for nodemask intersection inside task_lock() so that tsk->mems_allowed cannot change. This ensures that nothing can set this tsk's mems_allowed out from under us and also protects tsk->mempolicy.

irq_set_chained_handler sets 'desc->handle_irq'. However this irq is called by handle_nested_irq from handle_twl4030_pih, and that uses action->thread_fn.

2011-12-20perf record: Add ability to record event periodAndrew Vagin
The problem is that when SAMPLE_PERIOD is not set, the kernel generates a number of samples in proportion to an event's period. Number of these samples may be too big and the kernel throttles all samples above a defined limit. E.g.: I want to trace when a process sleeps. I created a process which sleeps for 1ms and for 4ms. perf got 100 events in both cases. swapper 0 [000] 1141.371830: sched_stat_sleep: comm=foo pid=1801 delay=1386750 [ns] swapper 0 [000] 1141.369444: sched_stat_sleep: comm=foo pid=1801 delay=4499585 [ns] In the first case a kernel want to send 4499585 events and in the second case it wants to send 1386750 events. perf-reports shows that process sleeps in both places equal time. Instead of this we can get only one sample with an attribute period. As result we have less data transferring between kernel and user-space and we avoid throttling of samples. The patch "events: Don't divide events if it has field period" added a kernel part of this functionality.

2011-12-19Revert "mmc: enable runtime PM by default"Ohad Ben-Cohen
When SDIO runtime PM was originally introduced, we immediately faced two regressions with two different chipsets, and in response decided not to enable it by default. With the recent work on the 8686 we hoped we found all the gotchas, so 08da834 did make sense (at least experimentally). Unfortunately we now see that some setups out there still refuse to work when SDIO runtime PM is enabled by default (see http://www.spinics.net/lists/linux-mmc/msg11161.html), and obviously we can't live with these kind of regressions.

Drop the "state" argument from sdhci_suspend_host. Its only user is the PCI glue; this allows to move all SDHCI glues to use dev_pm_ops instead. Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>

2011-12-19sctp: fix incorrect overflow check on autocloseXi Wang
Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for limiting the autoclose value. If userspace passes in -1 on 32-bit platform, the overflow check didn't work and autoclose would be set to 0xffffffff. This patch defines a max_autoclose (in seconds) for limiting the value and exposes it through sysctl, with the following intentions. 1) Avoid overflowing autoclose * HZ. 2) Keep the default autoclose bound consistent across 32- and 64-bit platforms (INT_MAX / HZ in this patch). 3) Keep the autoclose value consistent between setsockopt() and getsockopt() calls.

2011-12-19x86, dumpstack: Fix code bytes breakage due to missing KERN_CONTClemens Ladisch
When printing the code bytes in show_registers(), the markers around the byte at the fault address could make the printk() format string look like a valid log level and facility code. This would prevent this byte from being printed and result in a spurious newline: [ 7555.765589] Code: 8b 32 e9 94 00 00 00 81 7d 00 ff 00 00 00 0f 87 96 00 00 00 48 8b 83 c0 00 00 00 44 89 e2 44 89 e6 48 89 df 48 8b 80 d8 02 00 00 [ 7555.765683] 8b 48 28 48 89 d0 81 e2 ff 0f 00 00 48 c1 e8 0c 48 c1 e0 04 Add KERN_CONT where needed, and elsewhere in show_registers() for consistency.

In case a conditional jump is followed by a long jump, conditional jump target is one byte past the start of target instruction.
