net: tip: fix a couple kernel-doc markups

2021-01-14T18:30:24Z

A function has a different name between their prototype and its kernel-doc markup: ../net/tipc/link.c:2551: warning: expecting prototype for link_reset_stats(). Prototype was for tipc_link_reset_stats() instead ../net/tipc/node.c:1678: warning: expecting prototype for is the general link level function for message sending().

tipc: fix NULL deref in tipc_link_xmit()

2021-01-09T22:44:47Z

The buffer list can have zero skb as following path: tipc_named_node_up()->tipc_node_xmit()->tipc_link_xmit(), so we need to check the list before casting an &sk_buff.

tipc: do sanity check payload of a netlink message

2020-12-16T20:45:02Z

When we initialize nlmsghdr with no payload inside tipc_nl_compat_dumpit() the parsing function returns -EINVAL. We fix it by making the parsing call conditional.

xdp_return_frame_bulk() needs to pass a xdp_buff to __xdp_return(). strlcpy got converted to strscpy but here it makes no functional difference, so just keep the right code. Conflicts: net/netfilter/nf_tables_api.c Signed-off-by: Jakub Kicinski

net: tipc: prevent possible null deref of link

2020-12-08T23:53:41Z

`tipc_node_apply_property` does a null check on a `tipc_link_entry` pointer but also accesses the same pointer out of the null check block. This triggers a warning on Coverity Static Analyzer because we're implying that `e->link` can BE null. Move "Update MTU for node link entry" line into if block to make sure that we're not in a state that `e->link` is null. Signed-off-by: Cengiz Can Signed-off-by: David S. Miller

tipc: support 128bit node identity for peer removing
