Subject: [PATCH net-next 0/5] ipv4: Convert ip_route_input_slow() and its callers to dscp_t.
Date: Tue, 1 Oct 2024 21:28:30 +0200 [thread overview]
Message-ID: <cover.1727807926.git.gnault@redhat.com> (raw)
Prepare ip_route_input_slow() and its call chain to future conversion
of ->flowi4_tos.
The ->flowi4_tos field of "struct flowi4" is used in many different
places, which makes it hard to convert it from __u8 to dscp_t.
In order to avoid a big patch updating all its users at once, this
patch series gradually converts some users to dscp_t. Those users now
set ->flowi4_tos from a dscp_t variable that is converted to __u8 using
inet_dscp_to_dsfield().
When all users of ->flowi4_tos will use a dscp_t variable, converting
that field to dscp_t will just be a matter of removing all the
inet_dscp_to_dsfield() conversions.
This series concentrates on ip_route_input_slow() and its direct and
indirect callers.
Guillaume Nault (5):
ipv4: Convert icmp_route_lookup() to dscp_t.
ipv4: Convert ip_route_input() to dscp_t.
ipv4: Convert ip_route_input_noref() to dscp_t.
ipv4: Convert ip_route_input_rcu() to dscp_t.
ipv4: Convert ip_route_input_slow() to dscp_t.
