From: Jakub Kicinski Date: Tue, 9 Jul 2019 02:53:15 +0000 (-0700) Subject: net/tls: add missing prot info init X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ab232e61e728a08a2cb4ebb439d7d2aa75df89c9;p=openwrt%2Fstaging%2Fblogic.git net/tls: add missing prot info init Turns out TLS_TX in HW offload mode does not initialize tls_prot_info. Since commit 9cd81988cce1 ("net/tls: use version from prot") we actually use this field on the datapath. Luckily we always compare it to TLS 1.3, and assume 1.2 otherwise. So since zero is not equal to 1.3, everything worked fine. Fixes: 9cd81988cce1 ("net/tls: use version from prot") Signed-off-by: Jakub Kicinski Reviewed-by: Dirk van der Merwe Signed-off-by: David S.
