2011-12-20nilfs2: potential integer overflow in nilfs_ioctl_clean_segments()Haogang Chen1-0/+3
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 Rientjes1-5/+24
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.

2011-12-20mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handlerNeilBrown1-5/+8
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. So the handled set with irq_set_chained_handler is never called. So change to use request_threaded_irq instead - that sets the correct field. Tested on GTA04 Phoenux.

2011-12-19Revert "mmc: enable runtime PM by default"Ohad Ben-Cohen1-11/+0
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.

2011-12-19sctp: fix incorrect overflow check on autocloseXi Wang5-3/+21
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.
