Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says: ==================== pull request (net): ipsec 2020-06-19 1) Fix double ESP trailer insertion in IPsec crypto offload if netif_xmit_frozen_or_stopped is true. From Huy Nguyen. 2) Merge fixup for "remove output_finish indirection from xfrm_state_afinfo". From Stephen Rothwell. 3) Select CRYPTO_SEQIV for ESP as this is needed for GCM and several other encryption algorithms. Also modernize the crypto algorithm selections for ESP and AH, remove those that are maked as "MUST NOT" and add those that are marked as "MUST" be implemented in RFC 8221. From Eric Biggers. Please note the merge conflict between commit: a7f7f6248d97 ("treewide: replace '---help---' in Kconfig files with 'help'") from Linus' tree and commits: 7d4e39195925 ("esp, ah: consolidate the crypto algorithm selections") be01369859b8 ("esp, ah: modernize the crypto algorithm selections") from the ipsec tree. ==================== Signed-off-by: David S.
