This will provide fully accuracy to the mapcount calculation in the write protect faults, so page pinning will not get broken by false positive copy-on-writes. total_mapcount() isn't the right calculation needed in reuse_swap_page(), so this introduces a page_trans_huge_mapcount() that is effectively the full accurate return value for page_mapcount() if dealing with Transparent Hugepages, however we only use the page_trans_huge_mapcount() during COW faults where it strictly needed, due to its higher runtime cost. This also provide at practical zero cost the total_mapcount information which is needed to know if we can still relocate the page anon_vma to the local vma. If page_trans_huge_mapcount() returns 1 we can reuse the page no matter if it's a pte or a pmd_trans_huge triggering the fault, but we can only relocate the page anon_vma to the local vma->anon_vma if we're sure it's only this "vma" mapping the whole THP physical range. Kirill A. Shutemov discovered the problem with moving the page anon_vma to the local vma->anon_vma in a previous version of this patch and another problem in the way page_move_anon_rmap() was called. Andrew Morton discovered that CONFIG_SWAP=n wouldn't build in a previous version, because reuse_swap_page must be a macro to call page_trans_huge_mapcount from swap.h, so this uses a macro again instead of an inline function. With this change at least it's a less dangerous usage than it was before, because "page" is used only once now, while with the previous code reuse_swap_page(page++) would have called page_mapcount on page+1 and it would have increased page twice instead of just once. Dean Luick noticed an uninitialized variable that could result in a rmap inefficiency for the non-THP case in a previous version. Mike Marciniszyn said: : Our RDMA tests are seeing an issue with memory locking that bisects to : commit 61f5d698 ("mm: re-enable THP") : : The test program registers two rather large MRs (512M) and RDMA : writes data to a passive peer using the first and RDMA reads it back : into the second MR and compares that data. The sizes are chosen randomly : between 0 and 1024 bytes. : : The test will get through a few (<= 4 iterations) and then gets a : compare error. : : Tracing indicates the kernel logical addresses associated with the individual : pages at registration ARE correct , the data in the "RDMA read response only" : packets ARE correct. : : The "corruption" occurs when the packet crosse two pages that are not physically : contiguous. The second page reads back as zero in the program. : : It looks like the user VA at the point of the compare error no longer points to : the same physical address as was registered. : : This patch totally resolves the issue!

A concurrency issue about KSM in the function scan_get_next_rmap_item. task A (ksmd): |task B (the mm's task): | mm = slot->mm; | down_read(&mm->mmap_sem); | | ... | | spin_lock(&ksm_mmlist_lock); | | ksm_scan.mm_slot go to the next slot; | | spin_unlock(&ksm_mmlist_lock); | |mmput() -> | ksm_exit(): | |spin_lock(&ksm_mmlist_lock); |if (mm_slot && ksm_scan.mm_slot != mm_slot) { | if (!mm_slot->rmap_list) { | easy_to_free = 1; | ... | |if (easy_to_free) { | mmdrop(mm); | ... | |So this mm_struct may be freed in the mmput(). | up_read(&mm->mmap_sem); | As we can see above, the ksmd thread may access a mm_struct that already been freed to the kmem_cache. Suppose a fork will get this mm_struct from the kmem_cache, the ksmd thread then call up_read(&mm->mmap_sem), will cause mmap_sem.count to become -1. As suggested by Andrea Arcangeli, unmerge_and_remove_all_rmap_items has the same SMP race condition, so fix it too. My prev fix in function scan_get_next_rmap_item will introduce a different SMP race condition, so just invert the up_read/spin_unlock order as Andrea Arcangeli said.

Commit 702e5bc6 ("ocfs2: use generic posix ACL infrastructure") refactored code to use posix_acl_create. The problem with this function is that it is not mindful of the cluster wide inode lock making it unsuitable for use with ocfs2 inode creation with ACLs. For example, when used in ocfs2_mknod, this function can cause deadlock as follows. The parent dir inode lock is taken when calling posix_acl_create -> get_acl -> ocfs2_iop_get_acl which takes the inode lock again. This can cause deadlock if there is a blocked remote lock request waiting for the lock to be downconverted. And same deadlock happened in ocfs2_reflink. This fix is to revert back using ocfs2_init_acl.

Commit 743b5f14 ("ocfs2: take inode lock in ocfs2_iop_set/get_acl()") introduced this issue. ocfs2_setattr called by chmod command holds cluster wide inode lock when calling posix_acl_chmod. This latter function in turn calls ocfs2_iop_get_acl and ocfs2_iop_set_acl. These two are also called directly from vfs layer for getfacl/setfacl commands and therefore acquire the cluster wide inode lock. If a remote conversion request comes after the first inode lock in ocfs2_setattr, OCFS2_LOCK_BLOCKED will be set. And this will cause the second call to inode lock from the ocfs2_iop_get_acl() to block indefinetly. The deleted version of ocfs2_acl_chmod() calls __posix_acl_chmod() which does not call back into the filesystem. Therefore, we restore ocfs2_acl_chmod(), modify it slightly for locking as needed, and use that instead.

This fixes CVE-2016-0758. In the ASN.1 decoder, when the length field of an ASN.1 value is extracted, it isn't validated against the remaining amount of data before being added to the cursor. With a sufficiently large size indicated, the check: datalen - dp < 2 may then fail due to integer overflow. Fix this by checking the length indicated against the amount of remaining data in both places a definite length is determined. Whilst we're at it, make the following changes: (1) Check the maximum size of extended length does not exceed the capacity of the variable it's being stored in (len) rather than the type that variable is assumed to be (size_t). (2) Compare the EOC tag to the symbolic constant ASN1_EOC rather than the integer 0. (3) To reduce confusion, move the initialisation of len outside of: for (len = 0; n > 0; n--) { since it doesn't have anything to do with the loop counter n.

For ipgre interface in collect metadata mode, it doesn't make sense for the interface to be of ARPHRD_IPGRE type. The outer header of received packets is not needed, as all the information from it is present in metadata_dst. We already don't set ipgre_header_ops for collect metadata interfaces, which is the only consumer of mac_header pointing to the outer IP header. Just set the interface type to ARPHRD_NONE in collect metadata mode for ipgre (not gretap, that still correctly stays ARPHRD_ETHER) and reset mac_header. Fixes: a64b04d8 ("gre: do not assign header_ops in collect metadata mode") Fixes: 2e15ea39 ("ip_gre: Add support to collect tunnel metadata.")

When using conntrack helpers from OVS, a common configuration is to perform a lookup without specifying a helper, then go through a firewalling policy, only to decide to attach a helper afterwards. In this case, the initial lookup will cause a ct entry to be attached to the skb, then the later commit with helper should attach the helper and confirm the connection. However, the helper attachment has been missing. If the user has enabled automatic helper attachment, then this issue will be masked as it will be applied in init_conntrack(). It is also masked if the action is executed from ovs_packet_cmd_execute() as that will construct a fresh skb. This patch fixes the issue by making an explicit call to try to assign the helper if there is a discrepancy between the action's helper and the current skb->nfct.

The x86 exception table sorting was changed in commit 29934b0f ("x86/extable: use generic search and sort routines") to use the arch independent code in lib/extable.c. However, the patch was mangled somehow on its way into the kernel from the last version posted at [1]. The committed version kind of attempted to incorporate the changes of commit 548acf19 ("x86/mm: Expand the exception table logic to allow new handling options") as in _completely_ _ignoring_ the x86 specific 'handler' member of struct exception_table_entry. This effectively broke the sorting as entries will only partly be swapped now. Fortunately, the x86 Kconfig selects BUILDTIME_EXTABLE_SORT, so the exception table doesn't need to be sorted at runtime. However, in case that ever changes, we better not break the exception table sorting just because of that. [ Ard Biesheuvel points out that BUILDTIME_EXTABLE_SORT applies to the core image only, but we still rely on the sorting routines for modules in that case - Linus ] Fix this by providing a swap_ex_entry_fixup() macro that takes care of the 'handler' member.

The HDMI/DP audio output on ATI/AMD chips got broken due to the recent restructuring of chmap. Fortunately, Daniel Exner could bisect, and pointed the culprit commit [739ffee9: ALSA: hda - Add hdmi chmap verb programming ops to chmap object]. This commit moved some ops from hdmi_ops to chmap_ops, and reassigned the ops in the embedded chmap object in hdmi_spec instead. Unfortunately, the reassignment of these ops in patch_atihdmi() were moved into an if block that is performed only for old chips. Thus, on newer chips, the generic ops is still used, which doesn't work for such ATI/AMD chips. This patch addresses the regression, simply by moving the assignment of chmap ops to the right place.

Jamal Hadi Salim says: ==================== Some actions were broken in allowing for late binding of actions. Late binding workflow is as follows: a) create an action and provide all necessary parameters for it Optionally provide an index or let the kernel give you one. Example: sudo tc actions add action police rate 1kbit burst 90k drop index 1 b) later on bind to the pre-created action from a filter definition by merely specifying the index. Example: sudo tc filter add dev lo parent ffff: protocol ip prio 8 \ u32 match ip src 127.0.0.8/32 flowid 1:8 action police index 1 ==================== Signed-off-by: NDavid S.
