arm64/mm: Remove hack in mmap randomize layout

2015-09-13T16:07:59Z

commit d6c763afab142a85e4770b4bc2a5f40f256d5c5d upstream. Since commit 8a0a9bd4db63 ('random: make get_random_int() more random'), get_random_int() returns a random value for each call, so comment and hack introduced in mmap_rnd() as part of commit 1d18c47c735e ('arm64: MMU fault handling and page table management') are incorrects. Commit 1d18c47c735e seems to use the same hack introduced by commit a5adc91a4b44 ('powerpc: Ensure random space between stack and mmaps'), latter copied in commit 5a0efea09f42 ('sparc64: Sharpen address space randomization calculations.'). But both architectures were cleaned up as part of commit fa8cbaaf5a68 ('powerpc+sparc64/mm: Remove hack in mmap randomize layout') as hack is no more needed since commit 8a0a9bd4db63. So the present patch removes the comment and the hack around get_random_int() on AArch64's mmap_rnd(). Cc: David S.

crypto: caam - fix memory corruption in ahash_final_ctx

2015-09-13T16:07:59Z

commit b310c178e6d897f82abb9da3af1cd7c02b09f592 upstream. When doing pointer operation for accessing the HW S/G table, a value representing number of entries (and not number of bytes) must be used.

libfc: Fix fc_fcp_cleanup_each_cmd()

2015-09-13T16:07:59Z

commit 8f2777f53e3d5ad8ef2a176a4463a5c8e1a16431 upstream. Since fc_fcp_cleanup_cmd() can sleep this function must not be called while holding a spinlock. This patch avoids that fc_fcp_cleanup_each_cmd() triggers the following bug: BUG: scheduling while atomic: sg_reset/1512/0x00000202 1 lock held by sg_reset/1512: #0: (&(&fsp->scsi_pkt_lock)->rlock){+.-...}, at: [] fc_fcp_cleanup_each_cmd.isra.21+0xa5/0x150 [libfc] Preemption disabled at:[] fc_fcp_cleanup_each_cmd.isra.21+0xa5/0x150 [libfc] Call Trace: [] dump_stack+0x4f/0x7b [] __schedule_bug+0x6c/0xd0 [] __schedule+0x71a/0xa10 [] schedule+0x32/0x80 [] fc_seq_set_resp+0xac/0x100 [libfc] [] fc_exch_done+0x41/0x60 [libfc] [] fc_fcp_cleanup_each_cmd.isra.21+0xcf/0x150 [libfc] [] fc_eh_device_reset+0x1c3/0x270 [libfc] [] scsi_try_bus_device_reset+0x29/0x60 [] scsi_ioctl_reset+0x258/0x2d0 [] scsi_ioctl+0x150/0x440 [] sd_ioctl+0xad/0x120 [] blkdev_ioctl+0x1b6/0x810 [] block_ioctl+0x38/0x40 [] do_vfs_ioctl+0x2f8/0x530 [] SyS_ioctl+0x81/0xa0 [] system_call_fastpath+0x16/0x7a Signed-off-by: Bart Van Assche Signed-off-by: Vasu Dev Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

EDAC, ppc4xx: Access mci->csrows array elements properly

2015-09-13T16:07:59Z

commit 5c16179b550b9fd8114637a56b153c9768ea06a5 upstream. The commit de3910eb79ac ("edac: change the mem allocation scheme to make Documentation/kobject.txt happy") changed the memory allocation for the csrows member. But ppc4xx_edac was forgotten in the patch. Fix it.

localmodconfig: Use Kbuild files too

2015-09-13T16:07:59Z

commit c0ddc8c745b7f89c50385fd7aa03c78dc543fa7a upstream. In kbuild it is allowed to define objects in files named "Makefile" and "Kbuild". Currently localmodconfig reads objects only from "Makefile"s and misses modules like nouveau.

perf: Fix fasync handling on inherited events

2015-09-13T16:07:59Z

commit fed66e2cdd4f127a43fd11b8d92a99bdd429528c upstream. Vince reported that the fasync signal stuff doesn't work proper for inherited events. So fix that. Installing fasync allocates memory and sets filp->f_flags |= FASYNC, which upon the demise of the file descriptor ensures the allocation is freed and state is updated. Now for perf, we can have the events stick around for a while after the original FD is dead because of references from child events. So we cannot copy the fasync pointer around. We can however consistently use the parent's fasync, as that will be updated.

mm/hwpoison: fix page refcount of unknown non LRU page

2015-09-13T16:07:59Z

commit 4f32be677b124a49459e2603321c7a5605ceb9f8 upstream. After trying to drain pages from pagevec/pageset, we try to get reference count of the page again, however, the reference count of the page is not reduced if the page is still not on LRU list. Fix it by adding the put_page() to drop the page reference which is from __get_any_page().
