* [NETFILTER]: nf_conntrack_core: avoid taking nf_conntrack_lock in ↵Patrick McHardy2008-02-011-3/+3
| | | | | | | | | | | | nf_conntrack_alter_reply The conntrack is unconfirmed, so we have an exclusive reference, which means that the write_lock is definitely unneeded. A read_lock used to be needed for the helper lookup, but since we're using RCU for helpers now rcu_read_lock is enough. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [NETFILTER]: x_tables: return new table from {arp,ip,ip6}t_register_table()Alexey Dobriyan2008-02-011-1/+11
| | | | | | | | | | | | | | | | | | | | | Typical table module registers xt_table structure (i.e. packet_filter) and link it to list during it. We can't use one template for it because corresponding list_head will become corrupted. We also can't unregister with template because it wasn't changed at all and thus doesn't know in which list it is. So, we duplicate template at the very first step of table registration. Table modules will save it for use during unregistration time and actual filtering. Do it at once to not screw bisection. P.S.: renaming i.e. packet_filter => __packet_filter is temporary until full netnsization of table modules is done.

* SELinux: Enable dynamic enable/disable of the network access checksPaul Moore2008-01-291-1/+12
| | | | | | | | | | | | | | | | | | | | | | This patch introduces a mechanism for checking when labeled IPsec or SECMARK are in use by keeping introducing a configuration reference counter for each subsystem. In the case of labeled IPsec, whenever a labeled SA or SPD entry is created the labeled IPsec/XFRM reference count is increased and when the entry is removed it is decreased. In the case of SECMARK, when a SECMARK target is created the reference count is increased and later decreased when the target is removed. These reference counters allow SELinux to quickly determine if either of these subsystems are enabled. NetLabel already has a similar mechanism which provides the netlbl_enabled() function. This patch also renames the selinux_relabel_packet_permission() function to selinux_secmark_relabel_packet_permission() as the original name and description were misleading in that they referenced a single packet label which is not the case.

* [NETFILTER]: xt_TOS: Change semantic of mask valueJan Engelhardt2008-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the behavior of xt_TOS v1 so that the mask value the user supplies means "zero out these bits" rather than "keep these bits". This is more easy on the user, as (I would assume) people keep more bits than zeroing, so, an example: Action: Set bit 0x01. before (&): iptables -j TOS --set-tos 0x01/0xFE after (&~): iptables -j TOS --set-tos 0x01/0x01 This is not too "tragic" with xt_TOS, but where larger fields are used (e.g. proposed xt_MARK v2), `--set-xmar 0x01/0x01` vs. `--set-xmark 0x01/0xFFFFFFFE` really makes a difference. Other target(!) modules, such as xt_TPROXY also use &~ rather than &, so let's get to a common ground. (Since xt_TOS has not yet left the development tree en direction to mainline, the semantic can be changed as proposed without breaking iptables.)
