| | | | | | | | | | | Some of the files (issp_*) that are involved in the firmware loading have unclear licensing statements. Removing the problematic files and adapting the code to compile without them is easier and faster than getting legal advise to understand if the files are under a free software license or not.

| | | | | | | | | | | | | The samsung_extdisp driver for GT-I9500 was affected by CVE-2015-1800 and CVE-2015-1801. The Galaxy S3 uses an older version of this driver and is at least affected by CVE-2015-1801. Newer kernel versions for the GT-I9500 had the driver completely removed. I also found no indication that the driver is actually needed for the S3, so let's disable it. vulnerability disclosure and further information: http://blog.quarkslab.com/kernel-vulnerabilities-in-the-samsung-s4.html Signed-off-by: Wolfgang Wiedmeyer <wolfgit@wiedmeyer.de>

* ALSA: pcm : Call kill_fasync() in stream lockTakashi Iwai2017-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | Currently kill_fasync() is called outside the stream lock in snd_pcm_period_elapsed(). This is potentially racy, since the stream may get released even during the irq handler is running. Although snd_pcm_release_substream() calls snd_pcm_drop(), this doesn't guarantee that the irq handler finishes, thus the kill_fasync() call outside the stream spin lock may be invoked after the substream is detached, as recently reported by KASAN. As a quick workaround, move kill_fasync() call inside the stream lock. The fasync is rarely used interface, so this shouldn't have a big impact from the performance POV. Ideally, we should implement some sync mechanism for the proper finish of stream and irq handler. But this oneliner should suffice for most cases, so far.

* net: avoid signed overflows for SO_{SND|RCV}BUFFORCEEric Dumazet2017-01-081-2/+2
| | | | | | | | | | | | | | | | | | | CAP_NET_ADMIN users should not be allowed to set negative sk_sndbuf or sk_rcvbuf values, as it can lead to various memory corruptions, crashes, OOM... Note that before commit 82981930125a ("net: cleanups in sock_setsockopt()"), the bug was even more serious, since SO_SNDBUF and SO_RCVBUF were vulnerable. This needs to be backported to all known linux kernels. Again, many thanks to syzkaller team for discovering this gem.
