2017-07-15saa7134: fix warm Medion 7134 EEPROM readMaciej S. Szmigiero
commit 5a91206ff0d0548939f3e85a65fb76b400fb0e89 upstream. When saa7134 module driving a Medion 7134 card is reloaded reads of this card EEPROM (required for automatic detection of tuner model) will be corrupted due to I2C gate in DVB-T demod being left closed. This sometimes also happens on first saa7134 module load after a warm reboot. Fix this by opening this I2C gate before doing EEPROM read during i2c initialization. Signed-off-by: Maciej S.

2017-07-15x86/mm/pat: Don't report PAT on CPUs that don't support itMikulas Patocka
commit 99c13b8c8896d7bcb92753bf0c63a8de4326e78d upstream. The pat_enabled() logic is broken on CPUs which do not support PAT and where the initialization code fails to call pat_init(). Due to that the enabled flag stays true and pat_enabled() returns true wrongfully. As a consequence the mappings, e.g. for Xorg, are set up with the wrong caching mode and the required MTRR setups are omitted. To cure this the following changes are required: 1) Make pat_enabled() return true only if PAT initialization was invoked and successful. 2) Invoke init_cache_modes() unconditionally in setup_arch() and remove the extra callsites in pat_disable() and the pat disabled code path in pat_init(). Also rename __pat_enabled to pat_disabled to reflect the real purpose of this variable.

2017-07-15crypto: caam - fix gfp allocation flags (part I)Horia Geantă
commit 42cfcafb91dabb0f9d9e08396c39824535948c67 upstream. Changes in the SW cts (ciphertext stealing) code in commit 0605c41cc53ca ("crypto: cts - Convert to skcipher") revealed a problem in the CAAM driver: when cts(cbc(aes)) is executed and cts runs in SW, cbc(aes) is offloaded in CAAM; cts encrypts the last block in atomic context and CAAM incorrectly decides to use GFP_KERNEL for memory allocation. Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is set, i.e. remove MAY_BACKLOG flag. We split the fix in two parts - first is sent to -stable, while the second is not (since there is no known failure case).

2017-07-15staging: comedi: fix clean-up of comedi_class in comedi_init()Ian Abbott
commit a9332e9ad09c2644c99058fcf6ae2f355e93ce74 upstream. There is a clean-up bug in the core comedi module initialization functions, `comedi_init()`. If the `comedi_num_legacy_minors` module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to `class_destroy(comedi_class)` at the appropriate place in the clean-up sequence.

2017-07-15locking/rwsem-spinlock: Fix EINTR branch in __down_write_common()Kirill Tkhai
commit a0c4acd2c220376b4e9690e75782d0c0afdaab9f upstream. If a writer could been woken up, the above branch if (sem->count == 0) break; would have moved us to taking the sem. So, it's not the time to wake a writer now, and only readers are allowed now. Thus, 0 must be passed to __rwsem_do_wake(). Next, __rwsem_do_wake() wakes readers unconditionally. But we mustn't do that if the sem is owned by writer in the moment. Otherwise, writer and reader own the sem the same time, which leads to memory corruption in callers. rwsem-xadd.c does not need that, as: 1) the similar check is made lockless there, 2) in __rwsem_mark_wake::try_reader_grant we test, that sem is not owned by writer.

2017-07-15perf probe: Fix to probe on gcc generated symbols for offline kernelMasami Hiramatsu
commit 8a937a25a7e3c19d5fb3f9d92f605cf5fda219d8 upstream. Fix perf-probe to show probe definition on gcc generated symbols for offline kernel (including cross-arch kernel image). gcc sometimes optimizes functions and generate new symbols with suffixes such as ".constprop.N" or ".isra.N" etc. Since those symbol names are not recorded in DWARF, we have to find correct generated symbols from offline ELF binary to probe on it (kallsyms doesn't correct it). For online kernel or uprobes we don't need it because those are rebased on _text, or a section relative address. E.g. Without this: $ perf probe -k build-arm/vmlinux -F __slab_alloc* __slab_alloc.constprop.9 $ perf probe -k build-arm/vmlinux -D __slab_alloc p:probe/__slab_alloc __slab_alloc+0 If you put above definition on target machine, it should fail because there is no __slab_alloc in kallsyms. With this fix, perf probe shows correct probe definition on __slab_alloc.constprop.9: $ perf probe -k build-arm/vmlinux -D __slab_alloc p:probe/__slab_alloc __slab_alloc.constprop.9+0 Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/148350060434.19001.11864836288580083501.stgit@devbox Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Krister Johansen <kjlx@templeofstupid.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

In commit daeecbc0c431 ("perf tools: Add event_update event scale type"), the handling of PERF_EVENT_UPDATE__SCALE cast struct event_update_event->data to a pointer to event_update_event_scale, uses some field from this casted struct and then ends up falling through to the handling of another event type, PERF_EVENT_UPDATE__CPUS were it casts that ev->data to yet another type, oops, fix it by inserting the missing break.

If a TPM2 loses power without a TPM2_Shutdown command being issued (a "disorderly reboot"), it may lose some state that has yet to be persisted to NVRam, and will increment the DA counter. After the DA counter gets sufficiently large, the TPM will lock the user out. NOTE: This only changes behavior on TPM2 devices. Since TPM1 uses sysfs, and sysfs relies on implicit locking on chip->ops, it is not safe to allow this code to run in TPM1, or to add sysfs support to TPM2, until that locking is made explicit.

2017-07-15mqueue: fix a use-after-free in sys_mq_notify()Cong Wang
commit f991af3daabaecff34684fd51fac80319d1baad1 upstream. The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it.

2017-07-12rt286: add Thinkpad Helix 2 to force_combo_jack_tableYifeng Li
commit fe0dfd6358a17c79bd7d6996af7512ba452a7059 upstream. Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M broadwell-audio and rt286 codec. For all versions of Linux kernel, the stereo output doesn't work properly when earphones are plugged in, the sound was coming out from both channels even if the audio contains only the left or right channel. Furthermore, if a music recorded in stereo is played, the two channels cancle out each other out, as a result, no voice but only distorted background music can be heard, like a sound card with builtin a Karaoke sount effect. Apparently this tablet uses a combo jack with polarity incorrectly set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2 to force_combo_jack_table[] and the issue is resolved. The microphone input doesn't work regardless to the presence of this patch and still needs help from other developers to investigate. This is my first patch to LKML directly, sorry for CC-ing too many people here.

2017-07-12x86/uaccess: Optimize copy_user_enhanced_fast_string() for short stringsPaolo Abeni
commit 236222d39347e0e486010f10c1493e83dbbdfba8 upstream. According to the Intel datasheet, the REP MOVSB instruction exposes a pretty heavy setup cost (50 ticks), which hurts short string copy operations. This change tries to avoid this cost by calling the explicit loop available in the unrolled code for strings shorter than 64 bytes. The 64 bytes cutoff value is arbitrary from the code logic point of view - it has been selected based on measurements, as the largest value that still ensures a measurable gain. Micro benchmarks of the __copy_from_user() function with lengths in the [0-63] range show this performance gain (shorter the string, larger the gain): - in the [55%-4%] range on Intel Xeon(R) CPU E5-2690 v4 - in the [72%-9%] range on Intel Core i7-4810MQ Other tested CPUs - namely Intel Atom S1260 and AMD Opteron 8216 - show no difference, because they do not expose the ERMS feature bit.

2017-07-12pinctrl: mxs: atomically switch mux and drive strength configUwe Kleine-König
commit da6c2addf66d7ff7d0b090d6267d4292f951e4e6 upstream. To set the mux mode of a pin two bits must be set. Up to now this is implemented using the following idiom: writel(mask, reg + CLR); writel(value, reg + SET); . This however results in the mux mode being 0 between the two writes. On my machine there is an IC's reset pin connected to LCD_D20. The bootloader configures this pin as GPIO output-high (i.e. not holding the IC in reset). When Linux reconfigures the pin to GPIO the short time LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse the connected IC. The same problem is present for the pin's drive strength setting which is reset to low drive strength before using the right value. So instead of relying on the hardware to modify the register setting using two writes implement the bit toggling using read-modify-write.
