* [NETFILTER]: Kconfig: fix xt_physdev dependenciesPatrick McHardy2006-10-041-1/+1
| | | | | | | | | xt_physdev depends on bridge netfilter, which is a boolean, but can still be built modular because of special handling in the bridge makefile. Add a dependency on BRIDGE to prevent XT_MATCH_PHYSDEV=y, BRIDGE=m. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETFILTER]: x_tables: simplify compat APIPatrick McHardy2006-09-221-83/+109
| | | | | | | | | | | | Split the xt_compat_match/xt_compat_target into smaller type-safe functions performing just one operation. Handle all alignment and size-related conversions centrally in these function instead of requiring each module to implement a full-blown conversion function. Replace ->compat callback by ->compat_from_user and ->compat_to_user callbacks, responsible for converting just a single private structure.

* [NETFILTER]: ulog: fix panic on SMP kernelsMark Huang2006-08-131-0/+3
| | | | | | | | | | | | | | | | Fix kernel panic on various SMP machines. The culprit is a null ub->skb in ulog_send(). If ulog_timer() has already been scheduled on one CPU and is spinning on the lock, and ipt_ulog_packet() flushes the queue on another CPU by calling ulog_send() right before it exits, there will be no skbuff when ulog_timer() acquires the lock and calls ulog_send(). Cancelling the timer in ulog_send() doesn't help because it has already been scheduled and is running on the first CPU. Similar problem exists in ebt_ulog.c and nfnetlink_log.c.

* [SECURITY] secmark: nul-terminate secdataJames Morris2006-08-021-0/+2
| | | | | | | | | | | | | | | | | The patch below fixes a problem in the iptables SECMARK target, where the user-supplied 'selctx' string may not be nul-terminated. From initial analysis, it seems that the strlen() called from selinux_string_to_sid() could run until it arbitrarily finds a zero, and possibly cause a kernel oops before then. The impact of this appears limited because the operation requires CAP_NET_ADMIN, which is essentially always root. Also, the module is not yet in wide use.

* [NETFILTER]: xt_pkttype: fix mismatches on locally generated packetsPhil Oester2006-07-241-1/+11
| | | | | | | | | | | | | | | | | Locally generated broadcast and multicast packets have pkttype set to PACKET_LOOPBACK instead of PACKET_BROADCAST or PACKET_MULTICAST. This causes the pkttype match to fail to match packets of either type. The below patch remedies this by using the daddr as a hint as to broadcast|multicast. While not pretty, this seems like the only way to solve the problem short of just noting this as a limitation of the match.
