[-- Attachment #1: Type: text/plain, Size: 79134 bytes --]
On 3.19.0-rc4+, I encountered below error with attached test
case(bind_netlink.c). Please execute the following commands to reproduce
the error:
gcc -Wall -o bind_netlink bind_netlink.c
./bind_netlink 1000
By the way, if we run another test case(bind_tipc.c), the similar issue
will happen on TIPC socket.
Therefore, it seems that the issue is closely associated with rhashtable
instead of specific stacks like netlink or tipc.
Regards,
Ying

As removals can occur during resizes, entries may be referred to from
both tbl and future_tbl when the removal is requested. Therefore
rhashtable_remove() must unlink the entry in both tables if this is
the case. The existing code did search both tables but stopped when it
hit the first match.
Failing to do so resulted in use after remove.
Fixes: 97defe1 ("rhashtable: Per bucket locks & deferred expansion/shrinking")

Ying: This should fix the panic that was at the end of your TIPC
related boot log. I'm still working on the use after free.

Er, failing to do what? Stopping when it hit the first match?

Your below changes are reasonable for me. But after I applied the patch,
my reported two issues still happened :( And failure logs are completely
same before.

Hi Thomas,
I will be on vacation in next few days. So if you have an updated patch
resolving the issue, please let Richard(richard.alpe@ericsson.com) help
you to verify because he initially found the issue. After I identified
what it closely was related to rhashtable and it also happened in
netlink, I posted it on netdev mail list.
Regards,
Ying
