Tom Herbert 1913540a13 ila: Fix crash caused by rhashtable changes ... commit ca26893f05 ("rhashtable: Add rhlist interface") added a field to rhashtable_iter so that length became 56 bytes and would exceed the size of args in netlink_callback (which is 48 bytes). The netlink diag dump function already has been allocating a iter structure and storing the pointed to that in the args of netlink_callback. ila_xlat also uses rhahstable_iter but is still putting that directly in the arg block. Now since rhashtable_iter size is increased we are overwriting beyond the structure. The next field happens to be cb_mutex pointer in netlink_sock and hence the crash. Fix is to alloc the rhashtable_iter and save it as pointer in arg. Tested: modprobe ila ./ip ila add loc 3333:0:0:0 loc_match 2222:0:0:1, ./ip ila list # NO crash now Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S.
