In the current Documentation/md.txt, the lower limit value of stripe_cache_size is 16 and the default value is 128, but when I update kernel to the latest mainline version and RAID5 array is created by mdadm, then execute the following commands, it shows an error and a difference respectively. 1) set stripe_cache_size to 16 [root@localhost ~]# echo 16 > /sys/block/md0/md/stripe_cache_size bash: echo: write error: Invalid argument 2) read the default value of stripe_cache_size [root@localhost ~]# cat /sys/block/md0/md/stripe_cache_size 256 I read drivers/md/raid5.c and find the following related code: 1) in function 'raid5_set_cache_size': if (size <= 16 || size > 32768) return -EINVAL; 2) #define NR_STRIPES 256 So the lower limit value of stripe_cache_size should be 17 and the default value should be 256.

2016-06-16[media] videobuf2-v4l2: Verify planes array in buffer dequeueingSakari Ailus
When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer which will be dequeued is not known until the buffer has been removed from the queue. The number of planes is specific to a buffer, not to the queue. This does lead to the situation where multi-plane buffers may be requested and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument struct with fewer planes. __fill_v4l2_buffer() however uses the number of planes from the dequeued videobuf2 buffer, overwriting kernel memory (the m.planes array allocated in video_usercopy() in v4l2-ioctl.c) if the user provided fewer planes than the dequeued buffer had.

2016-06-15[media] media: fix use-after-free in cdev_put() when app exits after driver ↵Shuah Khan
unbind When driver unbinds while media_ioctl is in progress, cdev_put() fails with when app exits after driver unbinds. Add devnode struct device kobj as the cdev parent kobject. cdev_add() gets a reference to it and releases it in cdev_del() ensuring that the devnode is not deallocated as long as the application has the device file open. media_devnode_register() initializes the struct device kobj before calling cdev_add(). media_devnode_unregister() does cdev_del() and then deletes the device. devnode is released when the last reference to the struct device is gone. This problem is found on uvcvideo, em28xx, and au0828 drivers and fix has been tested on all three. kernel: [ 193.599736] BUG: KASAN: use-after-free in cdev_put+0x4e/0x50 kernel: [ 193.599745] Read of size 8 by task media_device_te/1851 kernel: [ 193.599792] INFO: Allocated in __media_device_register+0x54 kernel: [ 193.599951] INFO: Freed in media_devnode_release+0xa4/0xc0 kernel: [ 193.601083] Call Trace: kernel: [ 193.601093] [<ffffffff81aecac3>] dump_stack+0x67/0x94 kernel: [ 193.601102] [<ffffffff815359b2>] print_trailer+0x112/0x1a0 kernel: [ 193.601111] [<ffffffff8153b5e4>] object_err+0x34/0x40 kernel: [ 193.601119] [<ffffffff8153d9d4>] kasan_report_error+0x224/0x530 kernel: [ 193.601128] [<ffffffff814a2c3d>] ? kzfree+0x2d/0x40 kernel: [ 193.601137] [<ffffffff81539d72>] ? kfree+0x1d2/0x1f0 kernel: [ 193.601154] [<ffffffff8157ca7e>] ? cdev_put+0x4e/0x50 kernel: [ 193.601162] [<ffffffff8157ca7e>] cdev_put+0x4e/0x50 kernel: [ 193.601170] [<ffffffff815767eb>] __fput+0x52b/0x6c0 kernel: [ 193.601179] [<ffffffff8117743a>] ? switch_task_namespaces+0x2a kernel: [ 193.601188] [<ffffffff815769ee>] ____fput+0xe/0x10 kernel: [ 193.601196] [<ffffffff81170023>] task_work_run+0x133/0x1f0 kernel: [ 193.601204] [<ffffffff8117746e>] ? switch_task_namespaces+0x5e kernel: [ 193.601213] [<ffffffff8111b50c>] do_exit+0x72c/0x2c20 kernel: [ 193.601224] [<ffffffff8111ade0>] ? release_task+0x1250/0x1250 - - - kernel: [ 193.601360] [<ffffffff81003587>] ? exit_to_usermode_loop+0xe7 kernel: [ 193.601368] [<ffffffff810035c0>] exit_to_usermode_loop+0x120 kernel: [ 193.601376] [<ffffffff810061da>] syscall_return_slowpath+0x16a kernel: [ 193.601386] [<ffffffff82848b33>] entry_SYSCALL_64_fastpath+0xa6 Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> Tested-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-15[media] media-device: dynamically allocate struct media_devnodeMauro Carvalho Chehab
struct media_devnode is currently embedded at struct media_device. While this works fine during normal usage, it leads to a race condition during devnode unregister. the problem is that drivers assume that, after calling media_device_unregister(), the struct that contains media_device can be freed. This is not true, as it can't be freed until userspace closes all opened /dev/media devnodes. In other words, if the media devnode is still open, and media_device gets freed, any call to an ioctl will make the core to try to access struct media_device, with will cause an use-after-free and even GPF. Fix this by dynamically allocating the struct media_devnode and only freeing it when it is safe.

2016-06-15[media] media-devnode: fix namespace messMauro Carvalho Chehab
Along all media controller code, "mdev" is used to represent a pointer to struct media_device, and "devnode" for a pointer to struct media_devnode. However, inside media-devnode.[ch], "mdev" is used to represent a pointer to struct media_devnode. This is very confusing and may lead to development errors. So, let's change all occurrences at media-devnode.[ch] to also use "devnode" for such pointers. This patch doesn't make any functional changes.

2016-06-10Documentation/sphinx: add support for specifying extra export filesJani Nikula
Let the user specify file patterns where to look for the EXPORT_SYMBOLs in addition to the file with kernel-doc comments. This is directly based on the -export-file FILE option added to kernel-doc in "kernel-doc: add support for specifying extra files for EXPORT_SYMBOLs", but we extend that with globbing patterns in the Sphinx extension. The file patterns are added as options to the :export: and :internal: arguments of the kernel-doc directive. For example, to extract the documentation of exported functions from include/net/mac80211.h: .. kernel-doc:: include/net/mac80211.h :export: net/mac80211/*.c Without the file pattern, no exported functions would be found, as the EXPORT_SYMBOLs are placed in the various source files under net/mac80211. The matched files are also added as dependencies on the document in Sphinx, as they may affect the output. This is one of the reasons to do the globbing in the Sphinx extension instead of in scripts/kernel-doc. The file pattern remains optional, and is not needed if the kernel-doc comments and EXPORT_SYMBOLs are placed in the source file passed in as the main argument to the kernel-doc directive. This is the most common case across the kernel source tree. Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-06-10kernel-doc: add support for specifying extra files for EXPORT_SYMBOLsJani Nikula
If the kernel-doc comments for functions are not in the same file as the EXPORT_SYMBOL statements, the -export and -internal output selections do not work as expected. This is typically the case when the kernel-doc comments are in header files next to the function declarations and the EXPORT_SYMBOL statements are next to the function definitions in the source files. Let the user specify additional source files in which to look for the EXPORT_SYMBOLs using the new -export-file FILE option, which may be given multiple times. The pathological example for this is include/net/mac80211.h, which has all the kernel-doc documentation for the exported functions defined in a plethora of source files net/mac80211/*.c.

Jani Nikula says: Jon, this is v2 of [1] and [2], with a considerable amount of polish and fixes added. We started dogfooding this within drm-intel, and Daniel has reviewed the lot and contributed a number of fixes, most notably accurate file and line number references from Sphinx build errors/warnings to the kernel-doc comments in source code. We believe this is now in good shape for merging for v4.8. It's all in my sphinx-for-docs-next branch that you've already looked at; pull details below. When this lands in docs-next and we can backmerge to drm, we'll plunge ahead and convert gpu.tmpl to rst, and have that ready for v4.8. We think it's best to contribute that via the drm tree, as it'll involve splitting up the documentation and likely numerous updates to kernel-doc comments. I plan to update Documentation/kernel-doc-nano-HOWTO.txt for Sphinx and rst, obviously converting it to rst while at it.

This adds the missing auto-select bits for DVB-frontends and tuners (if MEDIA_SUBDRV_AUTOSELECT is enabled) which are used by the various rtl28xxu devices. The driver itself probes for three more tuners, but it's not actually using any of them: - MEDIA_TUNER_MT2063 - MEDIA_TUNER_MT2266 - MEDIA_TUNER_MXL5007T Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
