8f5d270 Linus Torvalds 22 June 2014, 05:01:15 UTC Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c new drivers from Wolfram Sang: "Here is a pull request from i2c hoping for the "new driver" rule. Originally, I wanted to send this request during the merge window, but code checkers with very recent additions complained, so a few fixups were needed. So, some more time went by and I merged rc1 to get a stable base" So the "new driver" rule is really about drivers that people absolutely need for the kernel to work on new hardware, which is not so much the case for i2c. So I considered not pulling this, but eventually relented. Just for FYI: the whole (and only) point of "new drivers" is not that new drivers cannot regress things (they can, and they have - by triggering badly tested code on machines that never triggered that code before), but because they can bring to life machines that otherwise wouldn't be useful at all without the drivers. So the new driver rule is for essential things that actual consumers would care about, ie devices like networking or disk drivers that matter to normal people (not server people - they run old kernels anyway, so mainlining new drivers is irrelevant for them). * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: sun6-p2wi: fix call to snprintf i2c: rk3x: add NULL entry to the end of_device_id array i2c: sun6i-p2wi: use proper return value in probe i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller support i2c: sunxi: add P2WI DT bindings documentation i2c: rk3x: add driver for Rockchip RK3xxx SoC I2C adapter 22 June 2014, 05:01:15 UTC

Nothing is actually built if this config is 'Y' and it just leads to more patches that add a select under a platform Kconfig so that some other CPUfreq option can be chosen.

c55f139 Miao Xie 19 June 2014, 02:42:54 UTC Btrfs: fix deadlock when mounting a degraded fs The deadlock happened when we mount degraded filesystem, the reproduced steps are following: # mkfs.btrfs -f -m raid1 -d raid1 <dev0> <dev1> # echo 1 > /sys/block/`basename <dev0>`/device/delete # mount -o degraded <dev1> <mnt> The reason was that the counter -- bi_remaining was wrong. If the missing or unwriteable device was the last device in the mapping array, we would not submit the original bio, so we shouldn't increase bi_remaining of it in btrfs_end_bio(), or we would skip the final endio handle. Fix this problem by adding a flag into btrfs bio structure. If we submit the original bio, we will set the flag, and we increase bi_remaining counter, or we don't. Though there is another way to fix it -- decrease bi_remaining counter of the original bio when we make sure the original bio is not submitted, this method need add more check and is easy to make mistake.

When run scrub with balance, sometimes -ENOENT will be returned, since in scrub_enumerate_chunks() will search dev_extent in *COMMIT_ROOT*, but btrfs_lookup_block_group() will search block group in *MEMORY*, so if a chunk is removed but not committed, -ENOENT will be returned. However, there is no need to stop scrubbing since other chunks may be scrubbed without problem. So this patch changes the behavior to skip removed chunks and continue to scrub the rest.

In fact, only the free space that is used to store the file data had this problem, the others didn't because the metadata of them is updated in the same transaction context. There are many methods which can fix the above problem - track the allocated space, and write it out when we write out the free space cache - account the size of the allocated space that is used to store the file data, if the size is not zero, don't write out the free space cache. The first one is complex and may make the performance drop down. This patch chose the second method, we use a per-block-group variant to account the size of that allocated space. Besides that, we also introduce a per-block-group read-write semaphore to avoid the race between the allocation and the free space cache write out.

ea4ebde Chris Mason 19 June 2014, 21:16:52 UTC Btrfs: fix deadlocks with trylock on tree nodes The Btrfs tree trylock function is poorly named. It always takes the spinlock and backs off if the blocking lock is held. This can lead to surprising lockups because people expect it to really be a trylock. This commit makes it a pure trylock, both for the spinlock and the blocking lock. It also reworks the nested lock handling slightly to avoid taking the read lock while a spinning write lock might be held. Signed-off-by: Chris Mason <clm@fb.com> 19 June 2014, 21:19:55 UTC
60efcf0 Rob Herring 12 June 2014, 17:52:44 UTC tty/serial: fix 8250 early console option passing to regular console In the conversion to generic early console, the passing of options from the early 8250 console to the regular ttyS console was broken. This resulted in the baud rate changing when switching consoles during boot. This feature allows specifying a single console option on the kernel command line rather than both an early console and regular serial tty console. It would be nice to generalize this feature. However, it only works if the correct baud rate can be probed early which is not the case on many platforms which have non-standard UART clock rates. So for now, this is left as an 8250 specific feature.

66528f9 Peter Hurley 16 June 2014, 12:10:42 UTC tty: Correct INPCK handling If INPCK is not set, input parity detection should be disabled. This means parity errors should not be received from the tty driver, and the data received should be treated normally. SUS v3, 11.2.2, General Terminal Interface - Input Modes, states: "If INPCK is set, input parity checking shall be enabled. If INPCK is not set, input parity checking shall be disabled, allowing output parity generation without input parity errors. Note that whether input parity checking is enabled or disabled is independent of whether parity detection is enabled or disabled (see Control Modes). If parity detection is enabled but input parity checking is disabled, the hardware to which the terminal is connected shall recognize the parity bit, but the terminal special file shall not check whether or not this bit is correctly set." Ignore parity errors reported by the tty driver when INPCK is not set, and handle the received data normally.

ef8b9dd Peter Hurley 16 June 2014, 12:10:41 UTC serial: Fix IGNBRK handling If IGNBRK is set without either BRKINT or PARMRK set, some uart drivers send a 0x00 byte for BREAK without the TTYBREAK flag to the line discipline, when it should send either nothing or the TTYBREAK flag set. This happens because the read_status_mask masks out the BI condition, which uart_insert_char() then interprets as a normal 0x00 byte. SUS v3 is clear regarding the meaning of IGNBRK; Section 11.2.2, General Terminal Interface - Input Modes, states: "If IGNBRK is set, a break condition detected on input shall be ignored; that is, not put on the input queue and therefore not read by any process." Fix read_status_mask to include the BI bit if IGNBRK is set; the lsr status retains the BI bit if a BREAK is recv'd, which is subsequently ignored in uart_insert_char() when masked with the ignore_status_mask.

A mixed bag of fixes, many of which feel just to late for 3.15. * hid sensors - some devices need a feature report request in order to change power state. This isn't part of the spec, but has been observed on several devices and does no harm to others. * mpl3115 has had two errors in the buffer description fixed. The presure is signed, not unsigned and the temperature has 12 bits rather than 16. These could lead to incorrect interpretation of the data in userspace. * tsl2x7x - the high byte of the proximity thresholds should be written along with the low byte (which was). This could lead to interesting results with large thresholds. * twl4030 - a flag to specify processed values were required was not set when initializing a reading. As such values returned were in an unknown state. Fixed by simply initializing it appropriately. * IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig build errors. * ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework already performs one. As such for big endian systems, the bytes would be in the wrong order in the magnetic field measurements reported. * mxs-lradc - the controllable voltage dividers were not enabled / disabled for later channels than the first one during conversion. * at91_adc error handling returned -ENOMEM in a u8. Return value of at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and also original values to be returned. * mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for NULL to detect an error. 18 June 2014, 17:41:08 UTC

883a1d4 Lars-Peter Clausen 18 June 2014, 11:32:35 UTC ALSA: control: Make sure that id->index does not overflow The ALSA control code expects that the range of assigned indices to a control is continuous and does not overflow. Currently there are no checks to enforce this. If a control with a overflowing index range is created that control becomes effectively inaccessible and unremovable since snd_ctl_find_id() will not be able to find it. This patch adds a check that makes sure that controls with a overflowing index range can not be created.

ac902c1 Lars-Peter Clausen 18 June 2014, 11:32:34 UTC ALSA: control: Handle numid overflow Each control gets automatically assigned its numids when the control is created. The allocation is done by incrementing the numid by the amount of allocated numids per allocation. This means that excessive creation and destruction of controls (e.g. via SNDRV_CTL_IOCTL_ELEM_ADD/REMOVE) can cause the id to eventually overflow. Currently when this happens for the control that caused the overflow kctl->id.numid + kctl->count will also over flow causing it to be smaller than kctl->id.numid. Most of the code assumes that this is something that can not happen, so we need to make sure that it won't happen Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jaroslav Kysela <perex@perex.cz> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> 18 June 2014, 13:13:23 UTC

82262a4 Lars-Peter Clausen 18 June 2014, 11:32:32 UTC ALSA: control: Fix replacing user controls There are two issues with the current implementation for replacing user controls. The first is that the code does not check if the control is actually a user control and neither does it check if the control is owned by the process that tries to remove it. That allows userspace applications to remove arbitrary controls, which can cause a user after free if a for example a driver does not expect a control to be removed from under its feed. The second issue is that on one hand when a control is replaced the user_ctl_count limit is not checked and on the other hand the user_ctl_count is increased (even though the number of user controls does not change). This allows userspace, once the user_ctl_count limit as been reached, to repeatedly replace a control until user_ctl_count overflows. Once that happens new controls can be added effectively bypassing the user_ctl_count limit. Both issues can be fixed by instead of open-coding the removal of the control that is to be replaced to use snd_ctl_remove_user_ctl(). This function does proper permission checks as well as decrements user_ctl_count after the control has been removed. Note that by using snd_ctl_remove_user_ctl() the check which returns -EBUSY at beginning of the function if the control already exists is removed. This is not a problem though since the check is quite useless, because the lock that is protecting the control list is released between the check and before adding the new control to the list, which means that it is possible that a different control with the same settings is added to the list after the check. Luckily there is another check that is done while holding the lock in snd_ctl_add(), so we'll rely on that to make sure that the same control is not added twice.

07f4d9d Lars-Peter Clausen 18 June 2014, 11:32:31 UTC ALSA: control: Protect user controls against concurrent access The user-control put and get handlers as well as the tlv do not protect against concurrent access from multiple threads. Since the state of the control is not updated atomically it is possible that either two write operations or a write and a read operation race against each other. Both can lead to arbitrary memory disclosure. This patch introduces a new lock that protects user-controls from concurrent access. Since applications typically access controls sequentially than in parallel a single lock per card should be fine.

2227901 Victor Kamensky 03 June 2014, 18:21:30 UTC arm64: ptrace: fix empty registers set in prstatus of aarch32 process core Currently core file of aarch32 process prstatus note has empty registers set. As result aarch32 core files create by V8 kernel are not very useful. It happens because compat_gpr_get and compat_gpr_set functions can copy registers values to/from either kbuf or ubuf. ELF core file collection function fill_thread_core_info calls compat_gpr_get with kbuf set and ubuf set to 0. But current compat_gpr_get and compat_gpr_set function handle copy to/from only ubuf case. Fix is to handle kbuf and ubuf as two separate cases in similar way as other functions like user_regset_copyout, user_regset_copyin do.
