2011-05-11mm: tracing: add missing GFP flags to tracingMel Gorman
include/linux/gfp.h and include/trace/events/gfpflags.h are out of sync. When tracing is enabled, certain flags are not recognised and the text output is less useful as a result. Add the missing flags.

2011-05-11tmpfs: fix spurious ENOSPC when racing with unswapHugh Dickins
Testing the shmem_swaplist replacements for igrab() revealed another bug: writes to /dev/loop0 on a tmpfs file which fills its filesystem were sometimes failing with "Buffer I/O error"s. These came from ENOSPC failures of shmem_getpage(), when racing with swapoff: the same could happen when racing with another shmem_getpage(), pulling the page in from swap in between our find_lock_page() and our taking the info->lock (though not in the single-threaded loop case). This is unacceptable, and surprising that I've not noticed it before: it dates back many years, but (presumably) was made a lot easier to reproduce in 2.6.36, which sited a page preallocation in the race window. Fix it by rechecking the page cache before settling on an ENOSPC error.

2011-05-11tmpfs: fix race between umount and swapoffHugh Dickins
The use of igrab() in swapoff's shmem_unuse_inode() is just as vulnerable to umount as that in shmem_writepage(). Fix this instance by extending the protection of shmem_swaplist_mutex right across shmem_unuse_inode(): while it's on the list, the inode cannot be evicted (and the filesystem cannot be unmounted) without shmem_evict_inode() taking that mutex to remove it from the list. But since shmem_writepage() might take that mutex, we should avoid making memory allocations or memcg charges while holding it: prepare them at the outer level in shmem_unuse(). When mem_cgroup_cache_charge() was originally placed, we didn't know until that point that the page from swap was actually a shmem page; but nowadays it's noted in the swap_map, so we're safe to charge upfront. For the radix_tree, do as is done in shmem_getpage(): preload upfront, but don't pin to the cpu; so we make a habit of refreshing the node pool, but might dip into GFP_NOWAIT reserves on occasion if subsequently preempted. With the allocation and charge moved out from shmem_unuse_inode(), we can also hold index map and info->lock over from finding the entry.

This igrap-iput pair was added in commit 1b1b32f2c6f6 "tmpfs: fix shmem_swaplist races" based on incorrect assumptions: igrab() protects the inode from concurrent eviction by deletion, but it does nothing to protect it from concurrent unmounting, which goes ahead despite the raised i_count. So this use of igrab() was wrong all along, but the race made much worse in 2.6.37 when commit 63997e98a3be "split invalidate_inodes()" replaced two attempts at invalidate_inodes() by a single evict_inodes(). Konstantin posted a plausible patch, raising sb->s_active too: I'm unsure whether it was correct or not; but burnt once by igrab(), I am sure that we don't want to rely more deeply upon externals here. Fix it by adding the inode to shmem_swaplist earlier, while the page lock on page in page cache still secures the inode against eviction, without artifically raising i_count. It was originally added later because shmem_unuse_inode() is liable to remove an inode from the list while it's unswapped; but we can guard against that by taking spinlock before dropping mutex.

2011-05-11memcg: allocate memory cgroup structures in local nodesAndi Kleen
Commit dde79e005a769 ("page_cgroup: reduce allocation overhead for page_cgroup array for CONFIG_SPARSEMEM") added a regression that the memory cgroup data structures all end up in node 0 because the first attempt at allocating them would not pass in a node hint. Since the initialization runs on CPU #0 it would all end up node 0. This is a problem on large memory systems, where node 0 would lose a lot of memory. Change the alloc_pages_exact() to alloc_pages_exact_nid(). This will still fall back to other nodes if not enough memory is available. [ RED-PEN: right now it would fall back first before trying vmalloc_node. Probably not the best strategy ... But I left it like that for now. ] Signed-off-by: Andi Kleen <ak@linux.intel.com> Reported-by: Doug Nelson Cc: David Rientjes <rientjes@google.com> Reviewed-by: Michal Hocko <mhocko@suse.cz> Cc: Dave Hansen <dave@linux.vnet.ibm.com> Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Reviewed-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-05-10slub: Revert "[PARISC] slub: fix panic with DISCONTIGMEM"David Rientjes
This reverts commit 4a5fa3590f09, which did not allow SLUB to be used on architectures that use DISCONTIGMEM without compiling NUMA support without CONFIG_BROKEN also set. The slub panic that it was intended to prevent is addressed by d9b41e0b54fd ("[PARISC] set memory ranges in N_NORMAL_MEMORY when onlined") on parisc so there is no further slub issues with such a configuration. The reverts allows SLUB now to be used on such architectures since there haven't been any reports of additional errors.

2011-05-10xfrm: Don't allow esn with disabled anti replay detectionSteffen Klassert
Unlike the standard case, disabled anti replay detection needs some nontrivial extra treatment on ESN. RFC 4303 states: Note: If a receiver chooses to not enable anti-replay for an SA, then the receiver SHOULD NOT negotiate ESN in an SA management protocol. Use of ESN creates a need for the receiver to manage the anti-replay window (in order to determine the correct value for the high-order bits of the ESN, which are employed in the ICV computation), which is generally contrary to the notion of disabling anti-replay for an SA. So return an error if an ESN state with disabled anti replay detection is inserted for now and add the extra treatment later if we need it.

2011-05-10xfrm: Assign the inner mode output function to the dst entrySteffen Klassert
As it is, we assign the outer modes output function to the dst entry when we create the xfrm bundle. This leads to two problems on interfamily scenarios. We might insert ipv4 packets into ip6_fragment when called from xfrm6_output. The system crashes if we try to fragment an ipv4 packet with ip6_fragment. This issue was introduced with git commit ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed). The second issue is, that we might insert ipv4 packets in netfilter6 and vice versa on interfamily scenarios. With this patch we assign the inner mode output function to the dst entry when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner mode is used and the right fragmentation and netfilter functions are called. We switch then to outer mode with the output_finish functions.
