Subject: [PATCH] Don't feed anything but regular iovec's to
|
||||
blk_rq_map_user_iov
|
||||
|
||||
In theory we could map other things, but there's a reason that function
|
||||
is called "user_iov". Using anything else (like splice can do) just
|
||||
confuses it.

Subject: [PATCH] net: avoid signed overflows for SO_{SND|RCV}BUFFORCE
|
||||
|
||||
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.
