3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Andreas Henriksson <andr...@fatal.se> [ Upstream commit 13eb2ab2d33c57ebddc57437a7d341995fc9138c ] When trying to delete a table >= 256 using iproute2 the local table will be deleted. The table id is specified as a netlink attribute when it needs more then 8 bits and iproute2 then sets the table field to RT_TABLE_UNSPEC (0). Preconditions to matching the table id in the rule delete code doesn't seem to take the "table id in netlink attribute" into condition so the frh_get_table helper function never gets to do its job when matching against current rule. Use the helper function twice instead of peaking at the table value directly.
