From: Guillaume Nault Date: Mon, 5 Jun 2023 21:55:25 +0000 (+0200) Subject: ipv4: Set correct scope in inet_csk_route_*(). X-Git-Tag: v6.5-rc1~163^2~164^2~1 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=4b095281cacab0b62e7f11d6d8c4a6d49ecaae42;p=tomoyo%2Ftomoyo-test1.git ipv4: Set correct scope in inet_csk_route_*(). RT_CONN_FLAGS(sk) overloads the tos parameter with the RTO_ONLINK bit when sk has the SOCK_LOCALROUTE flag set. This is only useful for ip_route_output_key_hash() to eventually adjust the route scope. Let's drop RTO_ONLINK and set the correct scope directly to avoid this special case in the future and to allow converting ->flowi4_tos to dscp_t.
