net: rename reference+tracking helpers

2022-06-10T04:52:55Z

Netdev reference helpers have a dev_ prefix for historic reasons. Renaming the old helpers would be too much churn but we can rename the tracking ones which are relatively recent and should be the default for new code. Rename: dev_hold_track() -> netdev_hold() dev_put_track() -> netdev_put() dev_replace_track() -> netdev_ref_replace() Link: https://lore.kernel.org/r/20220608043955.919359-1-kuba@kernel.org Signed-off-by: Jakub Kicinski

ipv6: add ipv6_dev_find to stubs

2021-03-30T20:29:39Z

Add ipv6_dev_find to ipv6_stub to allow lookup of net_devices by IPV6 address in net/ipv4/icmp.c. Signed-off-by: Andreas Roeseler Signed-off-by: David S. Miller

mld: convert ifmcaddr6 to RCU

2021-03-26T22:14:56Z

The ifmcaddr6 has been protected by inet6_dev->lock(rwlock) so that the critical section is atomic context. In order to switch this context, changing locking is needed. The ifmcaddr6 actually already protected by RTNL So if it's converted to use RCU, its control path context can be switched to sleepable.

net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup

2019-12-04T20:27:13Z

ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route(). This requires some changes in all the callers, as these two functions take different arguments and have different return types.
