Documentation: fix sctp_wmem in ip-sysctl.rst

2022-07-24T20:41:58+00:00

Since commit 1033990ac5b2 ("sctp: implement memory accounting on tx path"), SCTP has supported memory accounting on tx path where 'sctp_wmem' is used by sk_wmem_schedule(). So we should fix the description for this option in ip-sysctl.rst accordingly. v1->v2: - Improve the description as Marcelo suggested.

Documentation: fix udp_wmem_min in ip-sysctl.rst

2022-07-20T00:34:53+00:00

UDP doesn't support tx memory accounting, and sysctl udp_wmem_min is not really used anywhere. So we should fix the description in ip-sysctl.rst accordingly. Fixes: 95766fff6b9a ("[UDP]: Add memory accounting.")

ipv4: Fix data-races around sysctl_ip_dynaddr.

2022-07-13T11:56:49+00:00

While reading sysctl_ip_dynaddr, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Kuniyuki Iwashima Signed-off-by: David S. Miller

cipso: Fix data-races around sysctl.

2022-07-08T11:10:33+00:00

While reading cipso sysctl variables, they can be changed concurrently. So, we need to add READ_ONCE() to avoid data-races. Fixes: 446fda4f2682 ("[NetLabel]: CIPSOv4 engine") Signed-off-by: Kuniyuki Iwashima Acked-by: Paul Moore Signed-off-by: David S. Miller

Documentation: add description for net.sctp.ecn_enable

2022-06-11T05:18:20+00:00

Describe it in networking/ip-sysctl.rst like other SCTP options. Fixes: 2f5268a9249b ("sctp: allow users to set netns ecn flag with sysctl") Signed-off-by: Xin Long Acked-by: Marcelo Ricardo Leitner Signed-off-by: Jakub Kicinski

Documentation: add description for net.sctp.intl_enable

2022-06-11T05:18:20+00:00

Describe it in networking/ip-sysctl.rst like other SCTP options. We need to document this especially as when using the feature of User Message Interleaving, some socket options also needs to be set.

net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na

2022-05-31T09:36:57+00:00

RFC 9131 changes default behaviour of handling RX of NA messages when the corresponding entry is absent in the neighbour cache. The current implementation is limited to accept just unsolicited NAs. However, the RFC is more generic where it also accepts solicited NAs. Both types should result in adding a STALE entry for this case. Expand accept_untracked_na behaviour to also accept solicited NAs to be compliant with the RFC and rename the sysctl knob to accept_untracked_na.
