| |
Hi,
there is trouble with the option CONFIG_FILTER. The structure sk_filter used with patch 2.2.2 isn't defined in any header. Only the struct sock_filter is given in include/linux/filter.h. It looks like sk_filter and sock_filter are different structures because the sk_run_filter call in include/net/sock.h uses the entries insns and len of that new structure. That means something like
struct sk_filter { unsigned short len; atomic_t refcnt; struct sock_filter *insns; }
Besides this the change of sk_run_filter() in net/core/filter.c wasn't ported to include/linux/filter.h. The (inlined) function sk_filter_len() is missed (calculate the real length out of the numbers of blocks used??). And some macros are missed: SKF_NET_OFF, SKF_LL_OFF, SKF_AD_OFF, SKF_AD_PROTOCOL, SKF_AD_PKTTYPE, and SKF_AD_IFINDEX.
