Subject: [PATCH v1 net-next 0/4] net: Hold per-netns RTNL during netdev notifier registration.
Date: Sat, 4 Jan 2025 15:37:31 +0900	[thread overview]
Message-ID: <20250104063735.36945-1-kuniyu@amazon.com> (raw)

Patch 1 converts the global netdev notifier to blocking_notifier,
which will be called under per-netns RTNL without RTNL, then we
need to protect the ongoing netdev_chain users from unregistration.

Patch 2 ~ 4 adds per-netns RTNL for registration of the global
and per-netns netdev notifiers.


Kuniyuki Iwashima (4):
  net: Convert netdev_chain to blocking_notifier.
  net: Hold __rtnl_net_lock() in (un)?register_netdevice_notifier().
  net: Hold rtnl_net_lock() in (un)?register_netdevice_notifier_net().
  net: Hold rtnl_net_lock() in
    (un)?register_netdevice_notifier_dev_net().
