01e2d06 | Linus Torvalds | 12 July 2015, 22:00:20 UTC | Revert "drm/i915: Use crtc_state->active in primary check_plane func" This reverts commit dec4f799d0a4c9edae20512fa60b0a36f3299ca2. Jörg Otte reports a NULL pointder dereference due to this commit, as 'crtc_state' very much can be NULL: crtc_state = state->base.state ? intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL; So the change to test 'crtc_state->base.active' cannot possibly be correct as-is. There may be some other minimal fix (like just checking crtc_state for NULL), but I'm just reverting it now for the rc2 release, and people like Daniel Vetter who actually know this code will figure out what the right solution is in the longer term.

75a6f82 | Al Viro | 08 July 2015, 01:42:38 UTC | freeing unlinked file indefinitely delayed Normally opening a file, unlinking it and then closing will have the inode freed upon close() (provided that it's not otherwise busy and has no remaining links, of course). However, there's one case where that does *not* happen. Namely, if you open it by fhandle with cold dcache, then unlink() and close(). In normal case you get d_delete() in unlink(2) notice that dentry is busy and unhash it; on the final dput() it will be forcibly evicted from dcache, triggering iput() and inode removal. In this case, though, we end up with *two* dentries - disconnected (created by open-by-fhandle) and regular one (used by unlink()). The latter will have its reference to inode dropped just fine, but the former will not - it's considered hashed (it is on the ->s_anon list), so it will stay around until the memory pressure will finally do it in. As the result, we have the final iput() delayed indefinitely. It's trivial to reproduce - void flush_dcache(void) { system("mount -o remount,rw /"); } static char buf[20 * 1024 * 1024]; main() { int fd; union { struct file_handle f; char buf[MAX_HANDLE_SZ]; } x; int m; x.f.handle_bytes = sizeof(x); chdir("/root"); mkdir("foo", 0700); fd = open("foo/bar", O_CREAT | O_RDWR, 0600); close(fd); name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0); flush_dcache(); fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR); unlink("foo/bar"); write(fd, buf, sizeof(buf)); system("df ."); /* 20Mb eaten */ close(fd); system("df ."); /* should've freed those 20Mb */ flush_dcache(); system("df ."); /* should be the same as #2 */ } will spit out something like Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 303843 1131 100% / Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 322023 283282 21692 93% / - inode gets freed only when dentry is finally evicted (here we trigger than by remount; normally it would've happened in response to memory pressure hell knows when).

892e8ca | Stephen Smalley | 10 July 2015, 13:40:59 UTC | selinux: fix mprotect PROT_EXEC regression caused by mm change commit 66fc13039422ba7df2d01a8ee0873e4ef965b50b ("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 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.

6b5e741 | James Hogan | 17 April 2015, 09:44:16 UTC | MIPS: Pistachio: Support CDMM & Fast Debug Channel Implement the mips_cdmm_phys_base() platform callback to provide a default Common Device Memory Map (CDMM) physical base address for the Pistachio SoC. This allows the CDMM in each VPE to be configured and probed for devices, such as the Fast Debug Channel (FDC). The physical address chosen is just below the default CPC address, which appears to also be unallocated. The FDC IRQ is also usable on Pistachio, and is routed through the GIC, so implement the get_c0_fdc_int() platform callback using gic_get_c0_fdc_int(), so the FDC driver doesn't have to fall back to polling.

Move the workaround for interAptiv and proAptiv out of gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use the FDC interrupt.

cccf34e | Markos Chandras | 10 July 2015, 08:29:10 UTC | MIPS: c-r4k: Fix cache flushing for MT cores MT_SMP is not the only SMP option for MT cores. The MT_SMP option allows more than one VPE per core to appear as a secondary CPU in the system. Because of how CM works, it propagates the address-based cache ops to the secondary cores but not the index-based ones. Because of that, the code does not use IPIs to flush the L1 caches on secondary cores because the CM would have done that already. However, the CM functionality is independent of the type of SMP kernel so even in non-MT kernels, IPIs are not necessary. As a result of which, we change the conditional to depend on the CM presence. Moreover, since VPEs on the same core share the same L1 caches, there is no need to send an IPI on all of them so we calculate a suitable cpumask with only one VPE per core.

3324603 | Paul Moore | 09 July 2015, 18:20:36 UTC | selinux: don't waste ebitmap space when importing NetLabel categories 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.

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: Kirill A.

a6335fa | Alexander Sverdlin | 02 July 2015, 15:16:01 UTC | MIPS: bootmem: Don't use memory holes for page bitmap Commit f9a7febd leads to a fact that mapstart and therefore a page bitmap for bootmem allocator immediately follows initrd_end. This doesn't always work well on Octeon, where there are holes in PFN ranges (refer to 5b3b1688 and 4MB-aligned PFN allocation). Depending on the inird location it could happen, that mapstart would be in an area not allocated by plat_mem_setup() in arch/mips/cavium-octeon/setup.c, but in the alignment hole between initrd and the next PFN area. Later on this memory will be unconditionally made available to buddy allocator at the end of free_all_bootmem_core() (mm/bootmem.c). All of this results in Linux using the memory not designated for Linux in Octeon's plat_mem_setup(), which in turn means corruption of the memory used by another OS/baremetal code on the same SoC. It doesn't look to me as a problem of Octeon platform code, but rather as an inability of f9a7febd to deal correctly with the fragmented memory-mappings. Proposed fix moves the check for initrd address to the same calculation-loop in bootmem_init() (arch/mips/kernel/setup.c), which also accounts for kernel code location. This should result in mapstart located starting from the first PFN area after kernel code AND initrd.

19ee835 | Chris Wilson | 29 June 2015, 13:01:19 UTC | drm/i915: Declare the swizzling unknown for L-shaped configurations The old style of memory interleaving swizzled upto the end of the first even bank of memory, and then used the remainder as unswizzled on the unpaired bank - i.e. swizzling is not constant for all memory. This causes problems when we try to migrate memory and so the kernel prevents migration at all when we detect L-shaped inconsistent swizzling. However, this issue also extends to userspace who try to manually detile into memory as the swizzling for an individual page is unknown (it depends on its physical address only known to the kernel), userspace cannot correctly swizzle objects. v2: Mark the global swizzling as unknown rather than adjust the value reported to userspace.

673c2c3 | Chris Metcalf | 08 July 2015, 21:07:41 UTC | modpost: work correctly with tile coldtext sections The tilegx and tilepro compilers use .coldtext for their unlikely executed text section name, so an __attribute__((cold)) function will (when compiled with higher optimization levels) land in the .coldtext section. Modify modpost to add .coldtext to the set of OTHER_TEXT_SECTIONS so we don't get warnings about referencing such a section in an __ex_table block, and then also modify arch/tile/lib/memcpy_user_64.c so that it uses plain ".coldtext" instead of ".coldtext.memcpy". The latter naming is a relic of an earlier use of -ffunction-sections, which we no longer use by default.

Now that we have a mechanism for describing disparate PMUs and their interrupts in device tree, this patch makes use of these to describe the PMUs for all CPUs in the system. For consistency, the existing A15 PMU interrupt-affinity property is reflowed across two lines.
