Subject: macsec: fix validation failed in asynchronous operation.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b3bdc3acbb44d74d0b7ba4d97169577a2b46dc88;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

macsec: fix validation failed in asynchronous operation.

MACSec test failed when asynchronous crypto operations is used. It
encounters packet validation failed since macsec_skb_cb(skb)->valid
is always 'false'.

This patch adds missing "macsec_skb_cb(skb)->valid = true" in
macsec_decrypt_done() when "err == 0".
