[PATCH net-next v1 0/2] ipv6: make IPV6_FREEBIND and IPV6_TRANSPARENT lockless

Posted by Xuanqiang Luo 2 weeks ago

From: Xuanqiang Luo <luoxuanqiang@kylinos.cn>

Move both IPv6 setters to the lockless setsockopt path.

Patch 1 handles IPV6_FREEBIND.

Patch 2 handles IPV6_TRANSPARENT.

Xuanqiang Luo (2):
  ipv6: make IPV6_FREEBIND setsockopt lockless
  ipv6: make IPV6_TRANSPARENT setsockopt lockless

The changes are fine, they simply align IPv6 with what IP_FREEBIND and
IP_TRANSPARENT have been doing in ip_sockglue.c already.

However, both patches touch the same switch() in the same function and
do exactly the same thing. Please squash them into a single patch in
v2, no cover letter needed then.

Thanks!
