From: Ido Schimmel Date: Wed, 21 Aug 2024 12:52:49 +0000 (+0300) Subject: ipv4: icmp: Pass full DS field to ip_route_input() X-Git-Tag: v6.1.130~53 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=28e46a8c2103cdaa44024e5685172e46e0fb415c;p=thirdparty%2Fkernel%2Fstable.git ipv4: icmp: Pass full DS field to ip_route_input() [ Upstream commit 1c6f50b37f711b831d78973dad0df1da99ad0014 ] Align the ICMP code to other callers of ip_route_input() and pass the full DS field. In the future this will allow us to perform a route lookup according to the full DSCP value. No functional changes intended since the upper DSCP bits are masked when comparing against the TOS selectors in FIB rules and routes.
