commit 401879c5 upstream. The N_IRDA line discipline may access the previous line discipline's closed and already-fre private data on open [1]. The tty->disc_data field _never_ refers to valid data on entry to the line discipline's open() method. Rather, the ldisc is expected to initialize that field for its own use for the lifetime of the instance (ie. from open() to close() only).

commit f33798de upstream. commit 9ce119f3 ("tty: Fix GPF in flush_to_ldisc()") fixed a GPF caused by a line discipline which does not define a receive_buf() method. However, the vt driver (and speakup driver also) pushes selection data directly to the line discipline receive_buf() method via tty_ldisc_receive_buf(). Fix the same problem in tty_ldisc_receive_buf(). Signed-off-by:

commit 4392bf33 upstream. hid_ignore_special_drivers works fine until hid_scan_report autodetects and reassign devices (for hid-multitouch, hid-microsoft and hid-rmi). Simplify the handling of the parameter: if it is there, use hid-generic, no matter what, and if not, scan the device or rely on the hid_have_special_driver table. This was detected while trying to disable hid-multitouch on a Surface Pro cover which prevented to use the keyboard. Signed-off-by:

commit ac4cbedf upstream. There are still a couple of minor issues in the X.509 leap year handling: (1) To avoid doing a modulus-by-400 in addition to a modulus-by-100 when determining whether the year is a leap year or not, I divided the year by 100 after doing the modulus-by-100, thereby letting the compiler do one instruction for both, and then did a modulus-by-4. Unfortunately, I then passed the now-modified year value to mktime64() to construct a time value. Since this isn't a fast path and since mktime64() does a bunch of divisions, just condense down to "% 400". It's also easier to read. (2) The default month length for any February where the year doesn't divide by four exactly is obtained from the month_length[] array where the value is 29, not 28. This is fixed by altering the table. Reported-by:

commit 836b34a9 upstream. create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and create_uaxx_quirk() functions allocate the audioformat object by themselves and free it upon error before returning. However, once the object is linked to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be double-freed, eventually resulting in a memory corruption. This patch fixes these failures in the error paths by unlinking the audioformat object before freeing it. Based on a patch by Takashi Iwai <tiwai@suse.de> [Note for stable backports: this patch requires the commit 902eb7fd ('ALSA: usb-audio: Minor code cleanup in create_fixed_stream_quirk()')] Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1283358Reported-by:
