netfilter: nf_flow_table: fix big-endian integer overflow
In some configurations, gcc reports an integer overflow: net/netfilter/nf_flow_table_offload.c: In function 'nf_flow_rule_match': net/netfilter/nf_flow_table_offload.c:80:21: error: unsigned conversion from 'int' to '__be16' {aka 'short unsigned int'} changes value from '327680' to '0' [-Werror=overflow] mask->tcp.flags = TCP_FLAG_RST | TCP_FLAG_FIN; ^~~~~~~~~~~~ From what I can tell, we want the upper 16 bits of these constants, so they need to be shifted in cpu-endian mode. Fixes: c29f74e0df7a ("netfilter: nf_flow_table: hardware offload support") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
