[tipc-discussion] Subscription cancellation is broken

[Erik H. <eri...@gm...>]

Hi
a raw memcmp of the subscriptions wont work here:
https://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git/tree/net/tipc/topsrv.c#n236

The subscription in the list may have filter set to 0x0, 0x1 or 0x2, but the
received cancellation request this will always be 0x4
The result is that no sub will be found when processing the cancel request,
and events will be generated until you close the topology connection.
I made a real hacky workaround here:
