f5364c1 Linus Torvalds 10 June 2016, 19:10:02 UTC Merge branch 'stacking-fixes' (vfs stacking fixes from Jann) Merge filesystem stacking fixes from Jann Horn. * emailed patches from Jann Horn <jannh@google.com>: sched: panic on corrupted stack end ecryptfs: forbid opening files without mmap handler proc: prevent stacking filesystems on top 10 June 2016, 19:10:02 UTC
29d6455 Jann Horn 01 June 2016, 09:55:07 UTC sched: panic on corrupted stack end Until now, hitting this BUG_ON caused a recursive oops (because oops handling involves do_exit(), which calls into the scheduler, which in turn raises an oops), which caused stuff below the stack to be overwritten until a panic happened (e.g. via an oops in interrupt context, caused by the overwritten CPU index in the thread_info). Just panic directly. Signed-off-by: Jann Horn <jannh@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 10 June 2016, 19:09:43 UTC
2f36db7 Jann Horn 01 June 2016, 09:55:06 UTC ecryptfs: forbid opening files without mmap handler This prevents users from triggering a stack overflow through a recursive invocation of pagefault handling that involves mapping procfs files into virtual memory.

e54ad7f Jann Horn 01 June 2016, 09:55:05 UTC proc: prevent stacking filesystems on top This prevents stacking filesystems (ecryptfs and overlayfs) from using procfs as lower filesystem. There is too much magic going on inside procfs, and there is no good reason to stack stuff on top of procfs. (For example, procfs does access checks in VFS open handlers, and ecryptfs by design calls open handlers from a kernel thread that doesn't drop privileges or so.)

9d98bce Rui Wang 08 June 2016, 06:59:52 UTC x86/ioapic: Fix incorrect pointers in ioapic_setup_resources() On a 4-socket Brickland system, hot-removing one ioapic is fine. Hot-removing the 2nd one causes panic in mp_unregister_ioapic() while calling release_resource(). It is because the iomem_res pointer has already been released when removing the first ioapic. To explain the use of &res[num] here: res is assigned to ioapic_resources, and later in ioapic_insert_resources() we do: struct resource *r = ioapic_resources; for_each_ioapic(i) { insert_resource(&iomem_resource, r); r++; } Here 'r' is treated as an arry of 'struct resource', and the r++ ensures that each element of the array is inserted separately. Thus we should call release_resouce() on each element at &res[num]. Fix it by assigning the correct pointers to ioapics[i].iomem_res in ioapic_setup_resources().

This fixes warnings like: NOHZ: local_softirq_pending 282 ... which can happen when running things like selftests/x86. This will change perf's static percpu buffer usage in IST context.

0ca00fc Eli Cohen 09 June 2016, 21:07:40 UTC net/mlx5e: Fix blue flame quota logic Blue flame is a latency enhancement feature that allows the driver to write the packet data directly to the NIC's registers thus making the read of the packet data from host memory redundant. We maintain a quota for the blue flame which is reloaded whenever we identify that the hardware is processing send requests and processes them fast enough so by the time we post the next send request it was able to process all the pending ones. This indicates that the hardware is capable of processing more blue flame requests efficiently. The blue flame quota is decremented whenever we send using blue flame. The current code erroneously clears the budget if we did not use blue flame for the current post send operation and we fix it here.

Even if it was doing that, checking for IS_ERR_OR_NULL(p) and then returning PTR_ERR(p) would have cause bugs, since PTR_ERR(NULL) --> success, crash.

18aba41 Oleg Drokin 08 June 2016, 22:33:59 UTC mm/fadvise.c: do not discard partial pages with POSIX_FADV_DONTNEED I noticed that the logic in the fadvise64_64 syscall is incorrect for partial pages. While first page of the region is correctly skipped if it is partial, the last page of the region is mistakenly discarded. This leads to problems for applications that read data in non-page-aligned chunks discarding already processed data between the reads. A somewhat misguided application that does something like write(XX bytes (non-page-alligned)); drop the data it just wrote; repeat gets a significant penalty in performance as a result.

Tejun submitted commit 23d11a58a9a6 ("workqueue: skip flush dependency checks for legacy workqueues") for the legacy create*_workqueue() interface.

770a537 Gerald Schaefer 08 June 2016, 22:33:50 UTC mm: thp: broken page count after commit aa88b68c3b1d Christian Borntraeger reported a kernel panic after corrupt page counts, and it turned out to be a regression introduced with commit aa88b68c3b1d ("thp: keep huge zero page pinned until tlb flush"), at least on s390. put_huge_zero_page() was moved over from zap_huge_pmd() to release_pages(), and it was replaced by tlb_remove_page(). However, release_pages() might not always be triggered by (the arch-specific) tlb_remove_page(). On s390 we call free_page_and_swap_cache() from tlb_remove_page(), and not tlb_flush_mmu() -> free_pages_and_swap_cache() like the generic version, because we don't use the MMU-gather logic. Although both functions have very similar names, they are doing very unsimilar things, in particular free_page_xxx is just doing a put_page(), while free_pages_xxx calls release_pages(). This of course results in very harmful put_page()s on the huge zero page, on architectures where tlb_remove_page() is implemented in this way. It seems to affect only s390 and sh, but sh doesn't have THP support, so the problem (currently) probably only exists on s390.

67961f9 Mike Kravetz 08 June 2016, 22:33:42 UTC mm/hugetlb: fix huge page reserve accounting for private mappings When creating a private mapping of a hugetlbfs file, it is possible to unmap pages via ftruncate or fallocate hole punch. If subsequent faults repopulate these mappings, the reserve counts will go negative. This is because the code currently assumes all faults to private mappings will consume reserves. The problem can be recreated as follows: - mmap(MAP_PRIVATE) a file in hugetlbfs filesystem - write fault in pages in the mapping - fallocate(FALLOC_FL_PUNCH_HOLE) some pages in the mapping - write fault in pages in the hole This will result in negative huge page reserve counts and negative subpool usage counts for the hugetlbfs. Note that this can also be recreated with ftruncate, but fallocate is more straight forward. This patch modifies the routines vma_needs_reserves and vma_has_reserves to examine the reserve map associated with private mappings similar to that for shared mappings. However, the reserve map semantics for private and shared mappings are very different. This results in subtly different code that is explained in the comments.

3d5fdff Prasun Maiti 06 June 2016, 14:34:19 UTC wext: Fix 32 bit iwpriv compatibility issue with 64 bit Kernel iwpriv app uses iw_point structure to send data to Kernel. The iw_point structure holds a pointer. For compatibility Kernel converts the pointer as required for WEXT IOCTLs (SIOCIWFIRST to SIOCIWLAST). Some drivers may use iw_handler_def.private_args to populate iwpriv commands instead of iw_handler_def.private. For those case, the IOCTLs from SIOCIWFIRSTPRIV to SIOCIWLASTPRIV will follow the path ndo_do_ioctl(). Accordingly when the filled up iw_point structure comes from 32 bit iwpriv to 64 bit Kernel, Kernel will not convert the pointer and sends it to driver. So, the driver may get the invalid data. The pointer conversion for the IOCTLs (SIOCIWFIRSTPRIV to SIOCIWLASTPRIV), which follow the path ndo_do_ioctl(), is mandatory. This patch adds pointer conversion from 32 bit to 64 bit and vice versa, if the ioctl comes from 32 bit iwpriv to 64 bit Kernel.

However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the FSL DCU driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. Use flat regmap cache and specify max register to be large enouth to cover all registers available in LS1021a and Vybrids register space.
