Miller" <davem@...emloft.net> Subject: [ 013/110] net: flow_dissector: fix thoff for IPPROTO_AH 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Eric Dumazet <edumazet@...gle.com> [ Upstream commit b86783587b3d1d552326d955acee37eac48800f1 ] In commit 8ed781668dd49 ("flow_keys: include thoff into flow_keys for later usage"), we missed that existing code was using nhoff as a temporary variable that could not always contain transport header offset. This is not a problem for TCP/UDP because port offset (@poff) is 0 for these protocols.
