Can be reproduced when running dlm_controld (tested on 4.4.x, 4.12.4): # seq 1 100 | xargs -P0 -n1 dlm_tool join # seq 1 100 | xargs -P0 -n1 dlm_tool leave misc_register fails due to duplicate sysfs entry, which causes dlm_device_register to free ls->ls_device.name. In dlm_device_deregister the name was freed again, causing memory corruption. According to the comment in dlm_device_deregister the name should've been set to NULL when registration fails, so this patch does that. sysfs: cannot create duplicate filename '/dev/char/10:1' ------------[ cut here ]------------ warning: cpu: 1 pid: 4450 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x56/0x70 modules linked in: msr rfcomm dlm ccm bnep dm_crypt uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core videodev btusb media btrtl btbcm btintel bluetooth ecdh_generic intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm snd_hda_codec_hdmi irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel thinkpad_acpi pcbc nvram snd_seq_midi snd_seq_midi_event aesni_intel snd_hda_codec_realtek snd_hda_codec_generic snd_rawmidi aes_x86_64 crypto_simd glue_helper snd_hda_intel snd_hda_codec cryptd intel_cstate arc4 snd_hda_core snd_seq snd_seq_device snd_hwdep iwldvm intel_rapl_perf mac80211 joydev input_leds iwlwifi serio_raw cfg80211 snd_pcm shpchp snd_timer snd mac_hid mei_me lpc_ich mei soundcore sunrpc parport_pc ppdev lp parport autofs4 i915 psmouse e1000e ahci libahci i2c_algo_bit sdhci_pci ptp drm_kms_helper sdhci pps_core syscopyarea sysfillrect sysimgblt fb_sys_fops drm wmi video cpu: 1 pid: 4450 comm: dlm_test.exe not tainted 4.12.4-041204-generic hardware name: lenovo 232425u/232425u, bios g2et82ww (2.02 ) 09/11/2012 task: ffff96b0cbabe140 task.stack: ffffb199027d0000 rip: 0010:sysfs_warn_dup+0x56/0x70 rsp: 0018:ffffb199027d3c58 eflags: 00010282 rax: 0000000000000038 rbx: ffff96b0e2c49158 rcx: 0000000000000006 rdx: 0000000000000000 rsi: 0000000000000086 rdi: ffff96b15e24dcc0 rbp: ffffb199027d3c70 r08: 0000000000000001 r09: 0000000000000721 r10: ffffb199027d3c00 r11: 0000000000000721 r12: ffffb199027d3cd1 r13: ffff96b1592088f0 r14: 0000000000000001 r15: ffffffffffffffef fs: 00007f78069c0700(0000) gs:ffff96b15e240000(0000) knlgs:0000000000000000 cs: 0010 ds: 0000 es: 0000 cr0: 0000000080050033 cr2: 000000178625ed28 cr3: 0000000091d3e000 cr4: 00000000001406e0 call trace: sysfs_do_create_link_sd.isra.2+0x9e/0xb0 sysfs_create_link+0x25/0x40 device_add+0x5a9/0x640 device_create_groups_vargs+0xe0/0xf0 device_create_with_groups+0x3f/0x60 ?

The latest change of compat_sys_sigpending in commit 8f13621a ("sigpending(): move compat to native") has broken it in two ways. First, it tries to write 4 bytes more than userspace expects: sizeof(old_sigset_t) == sizeof(long) == 8 instead of sizeof(compat_old_sigset_t) == sizeof(u32) == 4. Second, on big endian architectures these bytes are being written in the wrong order. This bug was found by strace test suite. Reported-by:

Current ext4_expand_extra_isize just tries to expand extra isize, if someone is holding xattr lock or some check fails, it will give up. So rename its name to ext4_try_to_expand_extra_isize. Besides that, we clean up unnecessary check and move some relative checks into it. Signed-off-by:

ext4_xattr_inode_read() currently reads each block sequentially while waiting for io operation to complete before moving on to the next block. This prevents request merging in block layer. Add a ext4_bread_batch() function that starts reads for all blocks then optionally waits for them to complete. A similar logic is used in ext4_find_entry(), so update that code to use the new function. Signed-off-by:

When an xattr block has a single reference, block is updated inplace and it is reinserted to the cache. Later, a cache lookup is performed to see whether an existing block has the same contents. This cache lookup will most of the time return the just inserted entry so deduplication is not achieved. Running the following test script will produce two xattr blocks which can be observed in "File ACL: " line of debugfs output: mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G mount /dev/sdb /mnt/sdb touch /mnt/sdb/{x,y} setfattr -n user.1 -v aaa /mnt/sdb/x setfattr -n user.2 -v bbb /mnt/sdb/x setfattr -n user.1 -v aaa /mnt/sdb/y setfattr -n user.2 -v bbb /mnt/sdb/y debugfs -R 'stat x' /dev/sdb | cat debugfs -R 'stat y' /dev/sdb | cat This patch defers the reinsertion to the cache so that we can locate other blocks with the same contents.

After commit 62d1034f53e3 ("fortify: use WARN instead of BUG for now"), we get a warning about possible stack overflow from a memcpy that was not strictly bounded to the size of the local variable: inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2: include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=] We actually had a bug here that would have been found by the warning, but it was already fixed last year in commit 30a9d7af ("ext4: fix stack memory corruption with 64k block size"). This replaces the fixed-length structure on the stack with a variable-length structure, using the correct upper bound that tells the compiler that everything is really fine here. I also change the loop count to check for the same upper bound for consistency, but the existing code is already correct here. Note that while clang won't allow certain kinds of variable-length arrays in structures, this particular instance is fine, as the array is at the end of the structure, and the size is strictly bounded.

The dir_nlink feature has been enabled by default for new ext4 filesystems since e2fsprogs-1.41 in 2008, and was automatically enabled by the kernel for older ext4 filesystems since the dir_nlink feature was added with ext4 in kernel 2.6.28+ when the subdirectory count exceeded EXT4_LINK_MAX-1. Automatically adding the file system features such as dir_nlink is generally frowned upon, since it could cause the file system to not be mountable on older kernel, thus preventing the administrator from rolling back to an older kernel if necessary. In this case, the administrator might also want to disable the feature because glibc's fts_read() function does not correctly optimize directory traversal for directories that use st_nlinks field of 1 to indicate that the number of links in the directory are not tracked by the file system, and could fail to traverse the full directory hierarchy. Fortunately, in the past ten years very few users have complained about incomplete file system traversal by glibc's fts_read(). This commit also changes ext4_inc_count() to allow i_nlinks to reach the full EXT4_LINK_MAX links on the parent directory (including "." and "..") before changing i_links_count to be 1.

ext4_find_unwritten_pgoff() does not properly handle a situation when starting index is in the middle of a page and blocksize < pagesize. The following command shows the bug on filesystem with 1k blocksize: xfs_io -f -c "falloc 0 4k" \ -c "pwrite 1k 1k" \ -c "pwrite 3k 1k" \ -c "seek -a -r 0" foo In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048, SEEK_DATA) will return the correct result. Fix the problem by neglecting buffers in a page before starting offset. Reported-by:Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by:

This fixes a problem where the system gets stuck in a loop unable to wakeup via power button in s2idle. The problem happens because: - press power button: - system emits 0xc0 (power press), event ignored - system emits 0xc1 (power release), event processed, emited as KEY_POWER - set wakeup_mode to true - system goes to s2idle - press power button - system emits 0xc0 (power press), wakeup_mode is true, system wakes - system emits 0xc1 (power release), event processed, emited as KEY_POWER - system goes to s2idle again To avoid this situation, process the presses (which matches what intel-hid does too).

Visually, the images look the same, but the file size is now a lot smaller than before, and they don't use some XML tags that would cause them to be badly parsed by some ImageMagick versions, or to require a lot of memory by TeTex, with would break PDF output on some distributions" * tag 'media/v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (68 commits) media: atomisp2: array underflow in imx_enum_frame_size() media: atomisp2: array underflow in ap1302_enum_frame_size() media: atomisp2: Array underflow in atomisp_enum_input() media: platform: davinci: drop VPFE_CMD_S_CCDC_RAW_PARAMS media: platform: davinci: return -EINVAL for VPFE_CMD_S_CCDC_RAW_PARAMS ioctl media: venus: don't abuse dma_alloc for non-DMA allocations media: venus: hfi: fix error handling in hfi_sys_init_done() media: venus: fix compile-test build on non-qcom ARM platform media: venus: mark PM functions as __maybe_unused media: cec-notifier: small improvements media: pulse8-cec: persistent_config should be off by default media: cec: cec_transmit_attempt_done: ignore CEC_TX_STATUS_MAX_RETRIES media: staging: atomisp: array underflow in ioctl media: lirc: LIRC_GET_REC_RESOLUTION should return microseconds media: svg: avoid too long lines media: svg files: simplify files media: selection.svg: simplify the SVG file media: vimc: set id_table for platform drivers media: staging: atomisp: disable warnings with cc-disable-warning media: davinci: variable 'common' set but not used ... -

We've changed the discard command handling into parallel manner. But, in this change, I forgot decreasing the usage count of the bio which was used to send discard request. I'm sorry about that. Fixes: a0154344 ("ext4: send parallel discards on commit completions") Signed-off-by:

Pull GPIO fixes from Linus Walleij: - LP87565: set the proper output level for direction_output. - stm32: fix the kernel build by selecting the hierarchical irqdomain symbol properly - this happens to be done in the pin control framework but whatever, it had dependencies to GPIO so we need to apply it here. - Select the hierarchical IRQ domain also for Xgene. - Fix wakeups to work on MXC. - Fix up the device tree binding on Exar that went astray, also add the right bindings. - Fix the unwanted events for edges from the library. - Fix the unbalanced chanined IRQ on the Tegra. * tag 'gpio-v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio: tegra: fix unbalanced chained_irq_enter/exit gpiolib: skip unwanted events, don't convert them to opposite edge gpio: exar: Use correct property prefix and document bindings gpio: gpio-mxc: Fix: higher 16 GPIOs usable as wake source gpio: xgene-sb: select IRQ_DOMAIN_HIERARCHY pinctrl: stm32: select IRQ_DOMAIN_HIERARCHY instead of depends on gpio: lp87565: Set proper output level and direction for direction_output MAINTAINERS: Add entry for Whiskey Cove PMIC GPIO driver

Pull clk fixes from Stephen Boyd: "A handful of critical fixes for changes introduce this merge window. - The TI sci_clk_get() API was pretty broken and nobody noticed. - There were some CPUfreq crashes on C.H.I.P devices because we failed to propagate rates up the clk tree. - Also, the Intel Atom PMC clk driver needs to mark a clk critical if the firmware has it enabled already so that audio doesn't get killed on Baytrail. - Gemini devices have a dead serial console because the reset control usage in the serial driver assume one method of reset that gemini doesn't support (this will be fixed in the next version in the reset framework so this is the small fix for -rc series). - Finally we have two rate calculation fixes, one for Exynos and one for Meson SoCs, that fix rate inconsistencies" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: keystone: sci-clk: Fix sci_clk_get clk: meson: mpll: fix mpll0 fractional part ignored clk: samsung: exynos5420: The EPLL rate table corrections clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock clk: x86: Do not gate clocks enabled by the firmware clk: gemini: Fix reset regression -

Pull x86 fix from Thomas Gleixner: "The recent irq core changes unearthed API abuse in the HPET code, which manifested itself in a suspend/resume regression.
