[for-linus][PATCH 01/15] ring-buffer: Fix writing to the buffer with max_data_size

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The maximum ring buffer data size is the maximum size of data that can be recorded on the ring buffer. Events must be smaller than the sub buffer data size minus any meta data. This size is checked before trying to allocate from the ring buffer because the allocation assumes that the size will fit on the sub buffer. The maximum size was calculated as the size of a sub buffer page (which is currently PAGE_SIZE minus the sub buffer header) minus the size of the meta data of an individual event. But it missed the possible adding of a time stamp for events that are added long enough apart that the event meta data can't hold the time delta. When an event is added that is greater than the current BUF_MAX_DATA_SIZE minus the size of a time stamp, but still less than or equal to BUF_MAX_DATA_SIZE, the ring buffer would go into an infinite loop, looking for a page that can hold the event. Luckily, there's a check for this loop and after 1000 iterations and a warning is emitted and the ring buffer is disabled. But this should never happen. This can happen when a large event is added first, or after a long period where an absolute timestamp is prefixed to the event, increasing its size by 8 bytes. This passes the check and then goes into the algorithm that causes the infinite loop. For events that are the first event on the sub-buffer, it does not need to add a timestamp, because the sub-buffer itself contains an absolute timestamp, and adding one is redundant. The fix is to check if the event is to be the first event on the sub-buffer, and if it is, then do not add a timestamp. This also fixes 32 bit adding a timestamp when a read of before_stamp or write_stamp is interrupted. There's still no need to add that timestamp if the event is going to be the first event on the sub buffer. Also, if the buffer has "time_stamp_abs" set, then also check if the length plus the timestamp is greater than the BUF_MAX_DATA_SIZE.

[PATCH] drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x

by Hamza Mahfooz

There have recently been changes that break backwards compatibility, that were introduced into DMUB firmware (for DCN32x) concerning FPO and SubVP. So, since those are just power optimization features, we can just disable them unless the user is using a new enough version of DMUB firmware.

Our btrfs subvolume snapshot <source> <destination> utility enforces that <source> is the root of the subvolume, however this isn't enforced in the kernel.

patch "parport: parport_serial: Add Brainboxes device IDs and geometry" added to char-misc-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled parport: parport_serial: Add Brainboxes device IDs and geometry to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know.
