Subject: [PATCH net-next 0/2] rtnetlink: RTNL avoidance in rtnl_getlink()
Date: Mon, 18 May 2026 10:01:32 +0000 [thread overview]
Message-ID: <20260518100134.809042-1-edumazet@google.com> (raw)
Many shell scripts invoke iproute2 commands specifying a device by
its name.
This series improves their performance avoiding RTNL acquisition
for their (repeated) name->index conversion.
Eric Dumazet (2):
rtnetlink: use nla_nest_end_safe() in rtnl_fill_prop_list()
rtnetlink: do not acquire RTNL for RTM_GETLINK with
RTEXT_FILTER_NAME_ONLY
