commit 66fc1303 ("mm: shmem_zero_setup skip security check and lockdep conflict with XFS") caused a regression for SELinux by disabling any SELinux checking of mprotect PROT_EXEC on shared anonymous mappings. However, even before that regression, the checking on such mprotect PROT_EXEC calls was inconsistent with the checking on a mmap PROT_EXEC call for a shared anonymous mapping. On a mmap, the security hook is passed a NULL file and knows it is dealing with an anonymous mapping and therefore applies an execmem check and no file checks. On a mprotect, the security hook is passed a vma with a non-NULL vm_file (as this was set from the internally-created shmem file during mmap) and therefore applies the file-based execute check and no execmem check. Since the aforementioned commit now marks the shmem zero inode with the S_PRIVATE flag, the file checks are disabled and we have no checking at all on mprotect PROT_EXEC. Add a test to the mprotect hook logic for such private inodes, and apply an execmem check in that case. This makes the mmap and mprotect checking consistent for shared anonymous mappings, as well as for /dev/zero and ashmem.

The increased use of pdtlb/pitlb instructions seemed to increase the frequency of random segmentation faults building packages. Further, we had a number of cases where TLB inserts would repeatedly fail and all forward progress would stop. The Haskell ghc package caused a lot of trouble in this area. The final indication of a race in pte handling was this syslog entry on sibaris (C8000): swap_free: Unused swap offset entry 00000004 BUG: Bad page map in process mysqld pte:00000100 pmd:019bbec5 addr:00000000ec464000 vm_flags:00100073 anon_vma:0000000221023828 mapping: (null) index:ec464 CPU: 1 PID: 9176 Comm: mysqld Not tainted 4.0.0-2-parisc64-smp #1 Debian 4.0.5-1 Backtrace: [<0000000040173eb0>] show_stack+0x20/0x38 [<0000000040444424>] dump_stack+0x9c/0x110 [<00000000402a0d38>] print_bad_pte+0x1a8/0x278 [<00000000402a28b8>] unmap_single_vma+0x3d8/0x770 [<00000000402a4090>] zap_page_range+0xf0/0x198 [<00000000402ba2a4>] SyS_madvise+0x404/0x8c0 Note that the pte value is 0 except for the accessed bit 0x100. This bit shouldn't be set without the present bit. It should be noted that the madvise system call is probably a trigger for many of the random segmentation faults. In looking at the kernel code, I found the following problems: 1) The pte_clear define didn't take TLB lock when clearing a pte. 2) We didn't test pte present bit inside lock in exception support. 3) The pte and tlb locks needed to merged in order to ensure consistency between page table and TLB. This also has the effect of serializing TLB broadcasts on SMP systems. The attached change implements the above and a few other tweaks to try to improve performance. Based on the timing code, TLB purges are very slow (e.g., ~ 209 cycles per page on rp3440). Thus, I think it beneficial to test the split_tlb variable to avoid duplicate purges. Probably, all PA 2.0 machines have combined TLBs. I dropped using __flush_tlb_range in flush_tlb_mm as I realized all applications and most threads have a stack size that is too large to make this useful. I added some comments to this effect. Since implementing 1 through 3, I haven't had any random segmentation faults on mx3210 (rp3440) in about one week of building code and running as a Debian buildd.

The pointer to an AFU in the adapter's list of AFUs can be null if we're in the process of removing AFUs. The afu_list_lock doesn't guard against this. Say we have 2 slices, and we're in the process of removing cxl. - We remove the AFUs in order (see cxl_remove). In cxl_remove_afu for AFU 0, we take the lock, set adapter->afu[0] = NULL, and release the lock. - Then we get an slbia. In cxl_slbia we take the lock, and set afu = adapter->afu[0], which is NULL. - Therefore our attempt to check afu->enabled will blow up. Therefore, check if afu is a null pointer before dereferencing it.

At present we don't create efficient ebitmaps when importing NetLabel category bitmaps. This can present a problem when comparing ebitmaps since ebitmap_cmp() is very strict about these things and considers these wasteful ebitmaps not equal when compared to their more efficient counterparts, even if their values are the same. This isn't likely to cause problems on 64-bit systems due to a bit of luck on how NetLabel/CIPSO works and the default ebitmap size, but it can be a problem on 32-bit systems. This patch fixes this problem by being a bit more intelligent when importing NetLabel category bitmaps by skipping over empty sections which should result in a nice, efficient ebitmap.

Reading page fault handler code I've noticed that under right circumstances kernel would map anonymous pages into file mappings: if the VMA doesn't have vm_ops->fault() and the VMA wasn't fully populated on ->mmap(), kernel would handle page fault to not populated pte with do_anonymous_page(). Let's change page fault handler to use do_anonymous_page() only on anonymous VMA (->vm_ops == NULL) and make sure that the VMA is not shared. For file mappings without vm_ops->fault() or shred VMA without vm_ops, page fault on pte_none() entry would lead to SIGBUS. Signed-off-by: NKirill A.

Grab a reference on a network namespace of the 'rbd map' (in case of rbd) or 'mount' (in case of ceph) process and use that to open sockets instead of always using init_net and bailing if network namespace is anything but init_net. Be careful to not share struct ceph_client instances between different namespaces and don't add any code in the !CONFIG_NET_NS case. This is based on a patch from Hong Zhiguo <zhiguohong@tencent.com>. Signed-off-by: NIlya Dryomov <idryomov@gmail.com> Reviewed-by: NSage Weil <sage@redhat.com>
