Commit 1e39f384 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by:

It was found (by Sasha) that if you use a futex located in the gate area we get stuck in an uninterruptible infinite loop, much like the ZERO_PAGE issue. While looking at this problem, PeterZ realized you'll get into similar trouble when hitting any install_special_pages() mapping. And are there still drivers setting up their own special mmaps without page->mapping, and without special VM or pte flags to make get_user_pages fail? In most cases, if page->mapping is NULL, we do not need to retry at all: Linus points out that even /proc/sys/vm/drop_caches poses no problem, because it ends up using remove_mapping(), which takes care not to interfere when the page reference count is raised. But there is still one case which does need a retry: if memory pressure called shmem_writepage in between get_user_pages_fast dropping page table lock and our acquiring page lock, then the page gets switched from filecache to swapcache (and ->mapping set to NULL) whatever the refcount. Fault it back in to get the page->mapping needed for key->shared.inode. Reported-by:

The sanity check (timeout < 0) never works; the dividend is unsigned and so is the division, which should have been a signed division. long timeout = (ct->timeout.expires - jiffies) / HZ; if (timeout < 0) timeout = 0; This patch converts the time values to signed for the division. Signed-off-by:

Commit 2a95ea6c ("procfs: do not overflow get_{idle,iowait}_time for nohz") did not take into account that one some architectures jiffies and cputime use different units. This causes get_idle_time() to return numbers in the wrong units, making the idle time fields in /proc/stat wrong. Instead of converting the usec value returned by get_cpu_{idle,iowait}_time_us to units of jiffies, use the new function usecs_to_cputime64 to convert it to the correct unit of cputime64_t.

commit 8aacc9f5 ("mm/mempolicy.c: fix pgoff in mbind vma merge") is the slightly incorrect fix. Why? Think following case. 1. map 4 pages of a file at offset 0 [0123] 2. map 2 pages just after the first mapping of the same file but with page offset 2 [0123][23] 3. mbind() 2 pages from the first mapping at offset 2. mbind_range() should treat new vma is, [0123][23] |23| mbind vma but it does [0123][23] |01| mbind vma Oops. then, it makes wrong vma merge and splitting ([01][0123] or similar).

Commit 5e081591 "block: warn if tag is greater than real_max_depth" cleaned up blk_queue_end_tag() to warn when the tag is truly invalid (greater than real_max_depth). However, it changed behavior in the tag < max_depth case to not end the request. Leading to triggering of BUG_ON(blk_queued_rq(rq)) in the request completion path: http://marc.info/?l=linux-kernel&m=132204370518629&w=2 In order to allow blk_queue_resize_tags() to shrink the tag space blk_queue_end_tag() must always complete tags with a value less than real_max_depth regardless of the current max_depth. The comment about "handling the shrink case" seems to be what prompted changes in this space, so remove it and BUG on all invalid tags (made even simpler by Matthew's suggestion to use an unsigned compare).

Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver The previous patch breaks reset watchdog behaviour on the older hardware. It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or 6300ESB) is preserved and that the behaviour for newer hardware is changed. We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN bit in the SMI_EN register. So the new behaviour becomes: turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog. turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1 (ICHO till ICH5 + 6300ESB only) turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.

Bruce Fields notes that commit 778fc546 ("locks: fix tracking of inprogress lease breaks") introduced a possible error pointer dereference on failure to allocate memory. locks_conflict() will dereference the passed-in new lease lock structure that may be an error pointer. This means an open (without O_NONBLOCK set) on a file with a lease applied (generally only done when Samba or nfsd (with v4) is running) could crash if a kmalloc() fails. So instead of playing games with IS_ERROR() all over the place, just check the allocation failure early. That makes the code more straightforward, and avoids this possible bad pointer dereference.
