Take intialization of ->hook_entry[...], ->entries_size and ->nentries over there, pull the check for empty chains into the end of that sucker. Now it's self-contained, so we can move it up in the very beginning of translate_table() *and* we can rely on ->hook_entry[] being properly transliterated after it.

Split ebt_check_entry_size_and_hooks() in two parts - one that does sanity checks on pointers (basically, checks that we can safely use iterator from now on) and the rest of it (looking into details of entry). The loop applying ebt_check_entry_size_and_hooks() is split in two. Populating newinfo->hook_entry[] is done in the first part. Unused arguments killed.

No need to revisit a chain we'd already finished with during the check for current hook. It's either instant loop (which we'd just detected) or a duplicate work. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When peeking at the next packet in a child qdisc by calling dequeue/requeue, the upper qdisc qlen counter may get out of sync in case the requeue fails. The qdisc and the child qdisc both have their counter decremented, but since no packet is given to the upper qdisc it won't decrement its counter itself. requeue should not fail, so this is mostly for "correctness".

Convert HFSC to use qdisc_tree_decrease_len() and add a callback for deactivating a class when its child queue becomes empty. All queue purging goes through hfsc_purge_queue(), which is used in three cases: grafting, class creation (when a leaf class is turned into an intermediate class by attaching a new class) and class deletion. In all cases qdisc_tree_decrease_len() is needed. Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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>.

qlen adjustment should happen immediately in ->delete and not in the class destroy function because the reference count will not hit zero in ->delete (sch_api holds a reference) but in ->put. Since the qdisc lock is released between deletion of the class and final destruction this creates an externally visible error in the qlen counter.

We're seeing increasing namespace conflicts between the global class_destroy() function declared in linux/device.h, and the private function in the SELinux core code.

Add support for the ranged tag (tag type #5) to the CIPSOv4 protocol. The ranged tag allows for seven, or eight if zero is the lowest category, category ranges to be specified in a CIPSO option. Each range is specified by two unsigned 16 bit fields, each with a maximum value of 65534. The two values specify the start and end of the category range; if the start of the category range is zero then it is omitted.

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.

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: NPatrick McHardy <kaber@trash.net>

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.
