[PATCH v2 0/2] cipso: make cipso_v4_skbuff_delattr() fully remove the CIPSO options

[Ondrej Mosnacek <omosnace@redhat.com>]

This series aims to improve cipso_v4_skbuff_delattr() to fully
remove the CIPSO options instead of just clearing them with NOPs.
That is implemented in the second patch, while the first patch is
a bugfix for cipso_v4_delopt() that the second patch depends on.

Tested using selinux-testsuite a TMT/Beakerlib test from this PR:
https://src.fedoraproject.org/tests/selinux/pull-request/488

Changes in v2:
- drop the paranoid WARN_ON() usage
- reword the description of the second patch

v1: https://lore.kernel.org/linux-security-module/20240416152913.1527166-1-omosnace@redhat.com/

Ondrej Mosnacek (2):
  cipso: fix total option length computation
  cipso: make cipso_v4_skbuff_delattr() fully remove the CIPSO options
