Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says:
====================
pull request (net): ipsec 2022-09-29
1) Use the inner instead of the outer protocol for GSO on inter
address family tunnels. This fixes the GSO case for address
family tunnels. From Sabrina Dubroca.
2) Reset ipcomp_scratches with NULL when freed, otherwise
it holds obsolete address. From Khalid Masum.
3) Reinject transport-mode packets through workqueue
instead of a tasklet. The tasklet might take too
long to finish. From Liu Jian.
Please pull or let me know if there are problems.
