[PATCH 1/1] netfilter: nf_ct_tcp: pack nf_ct_tcp_flags to match user space

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On some platforms (here: Intel IXP4xx ARM big endian)
sizeof(struct nf_ct_tcp_flags) evaluates to 4 bytes while in the user
space code 2 bytes is hard coded.
Add "__attribute__ ((__packed__))" to enforce matching structure
sizes.
