x_tables matches and targets that require nf_conntrack_ipv[4|6] to work don't have enough information to load on demand these modules. This patch introduces the following changes to solve this issue: o nf_ct_l3proto_try_module_get: try to load the layer 3 connection tracker module and increases the refcount. o nf_ct_l3proto_module put: drop the refcount of the module.

The expectation mask has some particularities that requires a different handling. The protocol number fields can be set to non-valid protocols, ie. l3num is set to 0xFFFF. Since that protocol does not exist, the mask tuple will not be dumped. Moreover, this results in a kernel panic when nf_conntrack accesses the array of protocol handlers, that is PF_MAX (0x1F) long. This patch introduces the function ctnetlink_exp_dump_mask, that correctly dumps the expectation mask. Such function uses the l3num value from the expectation tuple that is a valid layer 3 protocol number. The value of the l3num mask isn't dumped since it is meaningless from the userspace side.

Add a slab cache for the SELinux inode security struct, one of which is allocated for every inode instantiated by the system. The memory savings are considerable. On 64-bit, instead of the size-128 cache, we have a slab object of 96 bytes, saving 32 bytes per object. After booting, I see about 4000 of these and then about 17,000 after a kernel compile. With this patch, we save around 530KB of kernel memory in the latter case. On 32-bit, the savings are about half of this. Signed-off-by:

Remove the call to sel_make_bools() from sel_fill_super(), as policy needs to be loaded before the boolean files can be created. Policy will never be loaded during sel_fill_super() as selinuxfs is kernel mounted during init and the only means to load policy is via selinuxfs. Also, the call to d_genocide() on the error path of sel_make_bools() is incorrect and replaced with sel_remove_bools(). Signed-off-by:

Unify the error path of sel_fill_super() so that all errors pass through the same point and generate an error message. Also, removes a spurious dput() in the error path which breaks the refcounting for the filesystem (litter_kill_super() will correctly clean things up itself on error). Signed-off-by:

This patch disables the automatic labeling of new inodes on disk when no policy is loaded. Discussion is here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180296 In short, we're changing the behavior so that when no policy is loaded, SELinux does not label files at all. Currently it does add an 'unlabeled' label in this case, which we've found causes problems later. SELinux always maintains a safe internal label if there is none, so with this patch, we just stick with that and wait until a policy is loaded before adding a persistent label on disk. The effect is simply that if you boot with SELinux enabled but no policy loaded and create a file in that state, SELinux won't try to set a security extended attribute on the new inode on the disk. This is the only sane behavior for SELinux in that state, as it cannot determine the right label to assign in the absence of a policy. That state usually doesn't occur, but the rawhide installer seemed to be misbehaving temporarily so it happened to show up on a test install. Signed-off-by:

Centralize the page migration functions in anticipation of additional tinkering. Creates a new file mm/migrate.c 1. Extract buffer_migrate_page() from fs/buffer.c 2. Extract central migration code from vmscan.c 3. Extract some components from mempolicy.c 4. Export pageout() and remove_from_swap() from vmscan.c 5. Make it possible to configure NUMA systems without page migration and non-NUMA systems with page migration. I had to so some #ifdeffing in mempolicy.c that may need a cleanup. Signed-off-by:

1. Only disable interrupts if there is actually something to free 2. Only dirty the pcp cacheline if we actually freed something. 3. Disable interrupts for each single pcp and not for cleaning all the pcps in all zones of a node. drain_node_pages is called every 2 seconds from cache_reap. This fix should avoid most disabling of interrupts. Signed-off-by:

The list_lock also protects the shared array and we call drain_array() with the shared array. Therefore we cannot go as far as I wanted to but have to take the lock in a way so that it also protects the array_cache in drain_pages. (Note: maybe we should make the array_cache locking more consistent? I.e. always take the array cache lock for shared arrays and disable interrupts for the per cpu arrays?) Signed-off-by:

And a parameter to drain_array to control the freeing of all objects and then use drain_array() to replace instances of drain_array_locked with drain_array. Doing so will avoid taking locks in those locations if the arrays are empty. Signed-off-by:

Christoph Lameter authored
cache_reap takes the l3->list_lock (disabling interrupts) unconditionally and then does a few checks and maybe does some cleanup. This patch makes cache_reap() only take the lock if there is work to do and then the lock is taken and released for each cleaning action. The checking of when to do the next reaping is done without any locking and becomes racy. Should not matter since reaping can also be skipped if the slab mutex cannot be acquired. The same is true for the touched processing. If we get this wrong once in awhile then we will mistakenly clean or not clean the shared cache. This will impact performance slightly. Note that the additional drain_array() function introduced here will fall out in a subsequent patch since array cleaning will now be very similar from all callers. Signed-off-by:

follow_hugetlb_page() walks a range of user virtual address and then fills in list of struct page * into an array that is passed from the argument list. It also gets a reference count via get_page(). For compound page, get_page() actually traverse back to head page via page_private() macro and then adds a reference count to the head page. Since we are doing a virt to pte look up, kernel already has a struct page pointer into the head page. So instead of traverse into the small unit page struct and then follow a link back to the head page, optimize that with incrementing the reference count directly on the head page. The benefit is that we don't take a cache miss on accessing page struct for the corresponding user address and more importantly, not to pollute the cache with a "not very useful" round trip of pointer chasing. This adds a moderate performance gain on an I/O intensive database transaction workload. Signed-off-by:

Quite a long time back, prepare_hugepage_range() replaced is_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to verify if an address range is suitable for a hugepage mapping. is_aligned_hugepage_range() stuck around, but only to implement prepare_hugepage_range() on archs which didn't implement their own. Most archs (everything except ia64 and powerpc) used the same implementation of is_aligned_hugepage_range(). On powerpc, which implements its own prepare_hugepage_range(), the custom version was never used. In addition, "is_aligned_hugepage_range()" was a bad name, because it suggests it returns true iff the given range is a good hugepage range, whereas in fact it returns 0-or-error (so the sense is reversed). This patch cleans up by abolishing is_aligned_hugepage_range(). Instead prepare_hugepage_range() is defined directly. Most archs use the default version, which simply checks the given region is aligned to the size of a hugepage. ia64 and powerpc define custom versions. The ia64 one simply checks that the range is in the correct address space region in addition to being suitably aligned. The powerpc version (just as previously) checks for suitable addresses, and if necessary performs low-level MMU frobbing to set up new areas for use by hugepages. No libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR). Signed-off-by:

The optional hugepage callback, hugetlb_free_pgd_range() is presently implemented non-trivially only on ia64 (but I plan to add one for powerpc shortly). It has its own prototype for the function in asm-ia64/pgtable.h. However, since the function is called from generic code, it make sense for its prototype to be in the generic hugetlb.h header file, as the protypes other arch callbacks already are (prepare_hugepage_range(), set_huge_pte_at(), etc.). This patch makes it so. Signed-off-by:
