neighbour: switch to standard rcu, instead of rcu_bh

2023-03-22T04:32:18+00:00

rcu_bh is no longer a win, especially for objects freed with standard call_rcu(). Switch neighbour code to no longer disable BH when not necessary. Signed-off-by: Eric Dumazet Signed-off-by: Jakub Kicinski

ipv6: fix skb drops in igmp6_event_query() and igmp6_event_report()

2022-03-03T17:47:06+00:00

While investigating on why a synchronize_net() has been added recently in ipv6_mc_down(), I found that igmp6_event_query() and igmp6_event_report() might drop skbs in some cases. Discussion about removing synchronize_net() from ipv6_mc_down() will happen in a different thread.

ipv6: separate ndisc_ns_create() from ndisc_send_ns()

2022-02-21T12:13:45+00:00

This patch separate NS message allocation steps from ndisc_send_ns(), so it could be used in other places, like bonding, to allocate and send IPv6 NS message. Also export ndisc_send_skb() and ndisc_ns_create() for later bonding usage. Signed-off-by: Hangbin Liu Signed-off-by: David S. Miller

ipv6: ndisc: adjust ndisc_ifinfo_sysctl_change prototype

2020-08-24T13:40:07+00:00

Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") changed ndisc_ifinfo_sysctl_change to take a kernel pointer. Adjust its prototype in net/ndisc.h as well to fix the following sparse warning: net/ipv6/ndisc.c:1838:5: error: symbol 'ndisc_ifinfo_sysctl_change' redeclared with different type (incompatible argument 3 (different address spaces)): net/ipv6/ndisc.c:1838:5: int extern [addressable] [signed] [toplevel] ndisc_ifinfo_sysctl_change( ... ) net/ipv6/ndisc.c: note: in included file (through include/net/ipv6.h): ./include/net/ndisc.h:496:5: note: previously declared as: ./include/net/ndisc.h:496:5: int extern [addressable] [signed] [toplevel] ndisc_ifinfo_sysctl_change( ... ) net/ipv6/ndisc.c: note: in included file (through include/net/ip6_route.h): Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") Cc: Christoph Hellwig Signed-off-by: Tobias Klauser Signed-off-by: David S.
