tipc: do sanity check payload of a netlink message

2020-12-16T20:45:02+00:00

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.

net: tipc: prevent possible null deref of link

2020-12-08T23:53:41+00:00

`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.

tipc: support 128bit node identity for peer removing

2020-12-05T01:40:27+00:00

We add the support to remove a specific node down with 128bit
node identifier, as an alternative to legacy 32-bit node address.

example:
$tipc peer remove identiy <1001002|16777777>
