* [NET_SCHED]: Fix endless loops caused by inaccurate qlen counters (part 1)Patrick McHardy2006-12-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | There are multiple problems related to qlen adjustment that can lead to an upper qdisc getting out of sync with the real number of packets queued, leading to endless dequeueing attempts by the upper layer code. All qdiscs must maintain an accurate q.qlen counter. There are basically two groups of operations affecting the qlen: operations that propagate down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the root qdisc and operations only affecting a subtree or single qdisc (change, graft, delete class). Since qlen changes during operations from the second group don't propagate to ancestor qdiscs, their qlen values become desynchronized. This patch adds a function to propagate qlen changes up the qdisc tree, optionally calling a callback function to perform qdisc-internal maintenance when the child qdisc becomes empty. The follow-up patches will convert all qdiscs to use this function where necessary. Noticed by Timo Steinbach <tsteinbach@astaro.com>.

* NetLabel: convert to an extensibile/sparse category bitmapPaul Moore2006-12-021-3/+99
| | | | | | | | | | | | | | | | The original NetLabel category bitmap was a straight char bitmap which worked fine for the initial release as it only supported 240 bits due to limitations in the CIPSO restricted bitmap tag (tag type 0x01). This patch converts that straight char bitmap into an extensibile/sparse bitmap in order to lay the foundation for other CIPSO tag types and protocols. This patch also has a nice side effect in that all of the security attributes passed by NetLabel into the LSM are now in a format which is in the host's native byte/bit ordering which makes the LSM specific code much simpler; look at the changes in security/selinux/ss/ebitmap.c as an example.

* [NETFILTER]: x_tables: add NFLOG targetPatrick McHardy2006-12-024-2/+21
| | | | | | | | | | | Add new NFLOG target to allow use of nfnetlink_log for both IPv4 and IPv6. Currently we have two (unsupported by userspace) hacks in the LOG and ULOG targets to optionally call to the nflog API. They lack a few features, namely the IPv4 and IPv6 LOG targets can not specify a number of arguments related to nfnetlink_log, while the ULOG target is only available for IPv4. Remove those hacks and add a clean way to use nfnetlink_log. Signed-off-by: Patrick McHardy <kaber@trash.net>

* [NETFILTER]: sip conntrack: better NAT handlingPatrick McHardy2006-12-021-1/+4
| | | | | | | | | | | | | | | | | | | | | | | The NAT handling of the SIP helper has a few problems: - Request headers are only mangled in the reply direction, From/To headers not at all, which can lead to authentication failures with DNAT in case the authentication domain is the IP address - Contact headers in responses are only mangled for REGISTER responses - Headers may be mangled even though they contain addresses not participating in the connection, like alternative addresses - Packets are droppen when domain names are used where the helper expects IP addresses This patch takes a different approach, instead of fixed rules what field to mangle to what content, it adds symetric mapping of From/To/Via/Contact headers, which allows to deal properly with echoed addresses in responses and foreign addresses not belonging to the connection.

* [UDP(-Lite)]: consolidate v4 and v6 get|setsockopt codeGerrit Renker2006-12-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch consolidates set/getsockopt code between UDP(-Lite) v4 and 6. The justification is that UDP(-Lite) is a transport-layer protocol and therefore the socket option code (at least in theory) should be AF-independent. Furthermore, there is the following code reduplication: * do_udp{,v6}_getsockopt is 100% identical between v4 and v6 * do_udp{,v6}_setsockopt is identical up to the following differerence --v4 in contrast to v4 additionally allows the experimental encapsulation types UDP_ENCAP_ESPINUDP and UDP_ENCAP_ESPINUDP_NON_IKE --the remainder is identical between v4 and v6 I believe that this difference is of little relevance. The advantages in not duplicating twice almost completely identical code. The patch further simplifies the interface of udp{,v6}_push_pending_frames, since for the second argument (struct udp_sock *up) it always holds that up = udp_sk(sk); where sk is the first function argument.
