[PATCH openEuler-1.0-LTS v2] xen-netback: don't produce zero-size SKB frags
by Ziyang Xuan 20 Feb '24
by Ziyang Xuan 20 Feb '24

From: Jan Beulich <jbeulich(a)suse.com>
stable inclusion
from stable-v4.19.306
commit 5bb8270789c88c0e4ad78c0de2f274f2275c7f6c
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YCSC
CVE: CVE-2023-46838
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit c7ec4f2d684e17d69bbdd7c4324db0ef5daac26a upstream.
While frontends may submit zero-size requests (wasting a precious slot),
core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs
support for compound pages") can't deal with SKBs when they have all
zero-size fragments. Respond to empty requests right when populating
fragments; all further processing is fragment based and hence won't
encounter these empty requests anymore.
In a way this should have been that way from the beginning: When no data
is to be transferred for a particular request, there's not even a point
in validating the respective grant ref. That's no different from e.g.
passing NULL into memcpy() when at the same time the size is 0.
This is XSA-448 / CVE-2023-46838.

From: Johan Hovold <johan(a)kernel.org>
stable inclusion
from stable-v4.19.191
commit 76d7fc0857bc4033415fcad905db13753d0febc7
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I926JG
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 1b8b20868a6d64cfe8174a21b25b74367bdf0560 ]
Drivers should return -ENOTTY ("Inappropriate I/O control operation")
when an ioctl isn't supported, while -EINVAL is used for invalid
arguments.
Fix up the TIOCMGET, TIOCMSET and TIOCGICOUNT helpers which returned
-EINVAL when a tty driver did not implement the corresponding
operations.
Note that the TIOCMGET and TIOCMSET helpers predate git and do not get a
corresponding Fixes tag below.
Fixes: d281da7ff6f7 ("tty: Make tiocgicount a handler")
