Clean up the various different email addresses of mine listed in the code to a single current and valid address. As Dave says his network merges for 2.6.28 are now done this seems a good point to send them in where they won't risk disrupting real changes.

2008-10-10cipso: Add support for native local labeling and fixup mapping namesPaul Moore2-21/+108
This patch accomplishes three minor tasks: add a new tag type for local labeling, rename the CIPSO_V4_MAP_STD define to CIPSO_V4_MAP_TRANS and replace some of the CIPSO "magic numbers" with constants from the header file. The first change allows CIPSO to support full LSM labels/contexts, not just MLS attributes. The second change brings the mapping names inline with what userspace is using, compatibility is preserved since we don't actually change the value. The last change is to aid readability and help prevent mistakes. Signed-off-by: Paul Moore <paul.moore@hp.com>
2008-10-10selinux: Set socket NetLabel based on connection endpointPaul Moore1-0/+74
Previous work enabled the use of address based NetLabel selectors, which while highly useful, brought the potential for additional per-packet overhead when used. This patch attempts to solve that by applying NetLabel socket labels when sockets are connect()'d. This should alleviate the per-packet NetLabel labeling for all connected sockets (yes, it even works for connected DGRAM sockets).

2008-10-10netlabel: Add functionality to set the security attributes of a packetPaul Moore1-39/+183
This patch builds upon the new NetLabel address selector functionality by providing the NetLabel KAPI and CIPSO engine support needed to enable the new packet-based labeling. The only new addition to the NetLabel KAPI at this point is shown below: * int netlbl_skbuff_setattr(skb, family, secattr) ... and is designed to be called from a Netfilter hook after the packet's IP header has been populated such as in the FORWARD or LOCAL_OUT hooks. This patch also provides the necessary SELinux hooks to support this new functionality. Smack support is not currently included due to uncertainty regarding the permissions needed to expand the Smack network access controls.

2008-10-10netlabel: Replace protocol/NetLabel linking with refrerence countsPaul Moore1-137/+98
NetLabel has always had a list of backpointers in the CIPSO DOI definition structure which pointed to the NetLabel LSM domain mapping structures which referenced the CIPSO DOI struct. The rationale for this was that when an administrator removed a CIPSO DOI from the system all of the associated NetLabel LSM domain mappings should be removed as well; a list of backpointers made this a simple operation. Unfortunately, while the backpointers did make the removal easier they were a bit of a mess from an implementation point of view which was making further development difficult. Since the removal of a CIPSO DOI is a realtively rare event it seems to make sense to remove this backpointer list as the optimization was hurting us more then it was helping. However, we still need to be able to track when a CIPSO DOI definition is being used so replace the backpointer list with a reference count. In order to preserve the current functionality of removing the associated LSM domain mappings when a CIPSO DOI is removed we walk the LSM domain mapping table, removing the relevant entries.

2008-10-09udp: complete port availability checkingEric Dumazet1-24/+19
While looking at UDP port randomization, I noticed it was litle bit pessimistic, not looking at type of sockets (IPV6/IPV4) and not looking at bound addresses if any. We should perform same tests than when binding to a specific port. This permits a cleanup of udp_lib_get_port() Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2008-10-09tcpv[46]: fix md5 pseudoheader address field orderingIlpo Järvinen1-2/+2
Maybe it's just me but I guess those md5 people made a mess out of it by having *_md5_hash_* to use daddr, saddr order instead of the one that is natural (and equal to what csum functions use). For the segment were sending, the original addresses are reversed so buff's saddr == skb's daddr and vice-versa.

2008-10-09inet: Make tunnel RX/TX byte counters more consistentHerbert Xu1-2/+5
This patch makes the RX/TX byte counters for IPIP, GRE and SIT more consistent. Previously we included the external IP headers on the way out but not when the packet is inbound. The new scheme is to count payload only in both directions. For IPIP and SIT this simply means the exclusion of the external IP header. For GRE this means that we exclude the GRE header as well.

2008-10-09gre: Add Transparent Ethernet BridgingHerbert Xu1-32/+174
This patch adds support for Ethernet over GRE encapsulation. This is exposed to user-space with a new link type of "gretap" instead of "gre". It will create an ARPHRD_ETHER device in lieu of the usual ARPHRD_IPGRE. Note that to preserver backwards compatibility all Transparent Ethernet Bridging packets are passed to an ARPHRD_IPGRE tunnel if its key matches and there is no ARPHRD_ETHER device whose key matches more closely.

2008-10-09gre: Add netlink interfaceHerbert Xu1-4/+243
This patch adds a netlink interface that will eventually displace the existing ioctl interface. It utilises the elegant rtnl_link_ops mechanism. This also means that user-space no longer needs to rely on the tunnel interface being of type GRE to identify GRE tunnels. The identification can now occur using rtnl_link_ops.

2008-10-09gre: Move MTU setting out of ipgre_tunnel_bind_devHerbert Xu1-5/+11
This patch moves the dev->mtu setting out of ipgre_tunnel_bind_dev. This is in prepartion of using rtnl_link where we'll need to make the MTU setting conditional on whether the user has supplied an MTU. This also requires the move of the ipgre_tunnel_bind_dev call out of the dev->init function so that we can access the user parameters later. This patch also adds a check to prevent setting the MTU below the minimum of 68. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-09gre: Use needed_headroomHerbert Xu1-7/+8
Now that we have dev->needed_headroom, we can use it instead of having a bogus dev->hard_header_len. This also allows us to include dev->hard_header_len in the MTU computation so that when we do have a meaningful hard_harder_len in future it is included automatically in figuring out the MTU. Incidentally, this fixes a bug where we ignored the needed_headroom field of the underlying device in calculating our own hard_header_len.

2008-10-08inet: cleanup of local_port_rangeEric Dumazet2-20/+19
I noticed sysctl_local_port_range[] and its associated seqlock sysctl_local_port_range_lock were on separate cache lines. Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values.

2008-10-08udp: Improve port randomizationEric Dumazet1-44/+12
Current UDP port allocation is suboptimal. We select the shortest chain to chose a port (out of 512) that will hash in this shortest chain. First, it can lead to give not so ramdom ports and ease give attackers more opportunities to break the system. Second, it can consume a lot of CPU to scan all table in order to find the shortest chain. Third, in some pathological cases we can fail to find a free port even if they are plenty of them. This patch zap the search for a short chain and only use one random seed. Problem of getting long chains should be addressed in another way, since we can obtain long chains with non random ports.

2008-10-08tcp: fix length used for checksum in a resetIlpo Järvinen1-1/+1
While looking for some common code I came across difference in checksum calculation between tcp_v6_send_(reset|ack) I couldn't explain. I checked both v4 and v6 and found out that both seem to have the same "feature". I couldn't find anything in rfc nor anywhere else which would state that md5 option should be ignored like it was in case of reset so I came to a conclusion that this is probably a genuine bug. I suspect that addition of md5 just was fooled by the excessive copy-paste code in those functions and the reset part was never tested well enough to find out the problem.

2008-10-08netfilter: xtables: move extension arguments into compound structure (1/6)Jan Engelhardt5-58/+36
The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).
