* 9p: transport API reorganizationEric Van Hensbergen2008-02-06
| | | | | | | | | | This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step.

* 9p: add support for sticky bitAnthony Liguori2008-02-06
| | | | | | | | | | | | GDM gets unhappy if /var/gdm doesn't have the sticky bit set. This patch adds support for the sticky bit in much the same way setuid/setgid is supported. With this patch, I can launch X from a v9fs rootfs (although I quickly run out of fds in the server once gnome starts up).

* 9p: create transport rpc cut-thruEric Van Hensbergen2008-02-06
| | | | | | | | | Add a new transport function which allows a cut-thru directly to the transport instead of processing request through the mux if the cut-thru exists. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The port offset calculations depend on the protocol family, but, as Adrian noticed, I broke this logic with the commit 5ee31fc1ecdcbc234c8c56dcacef87c8e09909d8 [INET]: Consolidate inet(6)_hash_connect.

* [SOCK] proto: Add hashinfo member to struct protoArnaldo Carvalho de Melo2008-02-03

Now only the lookup routines receive as a parameter a struct inet_hashtable. With this we further reuse code, reducing the difference among INET transport protocols. Eventually work has to be done on UDP and SCTP to make them share this infrastructure and get as a bonus inet_diag interfaces so that iproute can be used with these protocols. net-2.6/net/ipv4/inet_hashtables.c: struct proto | +8 struct inet_connection_sock_af_ops | +8 2 structs changed __inet_hash_nolisten | +18 __inet_hash | -210 inet_put_port | +8 inet_bind_bucket_create | +1 __inet_hash_connect | -8 5 functions changed, 27 bytes added, 218 bytes removed, diff: -191 net-2.6/net/core/sock.c: proto_seq_show | +3 1 function changed, 3 bytes added, diff: +3 net-2.6/net/ipv4/inet_connection_sock.c: inet_csk_get_port | +15 1 function changed, 15 bytes added, diff: +15 net-2.6/net/ipv4/tcp.c: tcp_set_state | -7 1 function changed, 7 bytes removed, diff: -7 net-2.6/net/ipv4/tcp_ipv4.c: tcp_v4_get_port | -31 tcp_v4_hash | -48 tcp_v4_destroy_sock | -7 tcp_v4_syn_recv_sock | -2 tcp_unhash | -179 5 functions changed, 267 bytes removed, diff: -267 net-2.6/net/ipv6/inet6_hashtables.c: __inet6_hash | +8 1 function changed, 8 bytes added, diff: +8 net-2.6/net/ipv4/inet_hashtables.c: inet_unhash | +190 inet_hash | +242 2 functions changed, 432 bytes added, diff: +432 vmlinux: 16 functions changed, 485 bytes added, 492 bytes removed, diff: -7 /home/acme/git/net-2.6/net/ipv6/tcp_ipv6.c: tcp_v6_get_port | -31 tcp_v6_hash | -7 tcp_v6_syn_recv_sock | -9 3 functions changed, 47 bytes removed, diff: -47 /home/acme/git/net-2.6/net/dccp/proto.c: dccp_destroy_sock | -7 dccp_unhash | -179 dccp_hash | -49 dccp_set_state | -7 dccp_done | +1 5 functions changed, 1 bytes added, 242 bytes removed, diff: -241 /home/acme/git/net-2.6/net/dccp/ipv4.c: dccp_v4_get_port | -31 dccp_v4_request_recv_sock | -2 2 functions changed, 33 bytes removed, diff: -33 /home/acme/git/net-2.6/net/dccp/ipv6.c: dccp_v6_get_port | -31 dccp_v6_hash | -7 dccp_v6_request_recv_sock | +5 3 functions changed, 5 bytes added, 38 bytes removed, diff: -33 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

* [NETNS]: Lookup in FIB semantic hashes taking into account the namespace.Denis V. Lunev2008-01-31
| | | | | | | | | | | | | The namespace is not available in the fib_sync_down_addr, add it as a parameter. Looking up a device by the pointer to it is OK.

* [IPV4] route cache: Introduce rt_genid for smooth cache invalidationEric Dumazet2008-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | Current ip route cache implementation is not suited to large caches. We can consume a lot of CPU when cache must be invalidated, since we currently need to evict all cache entries, and this eviction is sometimes asynchronous. min_delay & max_delay can somewhat control this asynchronism behavior, but whole thing is a kludge, regularly triggering infamous soft lockup messages. When entries are still in use, this also consumes a lot of ram, filling dst_garbage.list. A better scheme is to use a generation identifier on each entry, so that cache invalidation can be performed by changing the table identifier, without having to scan all entries. No more delayed flushing, no more stalling when secret_interval expires. Invalidated entries will then be freed at GC time (controled by ip_rt_gc_timeout or stress), or when an invalidated entry is found in a chain when an insert is done. Thus we keep a normal equilibrium. This patch : - renames rt_hash_rnd to rt_genid (and makes it an atomic_t) - Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit) - Checks entry->rt_genid at appropriate places :

* [IPSEC]: Add support for combined mode algorithmsHerbert Xu2008-01-31
| | | | | | | | | | | | | | | | This patch adds support for combined mode algorithms with GCM being the first algorithm supported. Combined mode algorithms can be added through the xfrm_user interface using the new algorithm payload type XFRMA_ALG_AEAD. Each algorithms is identified by its name and the ICV length. For the purposes of matching algorithms in xfrm_tmpl structures, combined mode algorithms occupy the same name space as encryption algorithms. This is in line with how they are negotiated using IKE.

* [IPSEC]: Use crypto_aead and authenc in ESPHerbert Xu2008-01-31
| | | | | | | | | This patch converts ESP to use the crypto_aead interface and in particular the authenc algorithm. This lays the foundations for future support of combined mode algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* NetLabel: Introduce static network labels for unlabeled connectionsPaul Moore2008-01-29
| | | | | | | | | | | | | | | | | | Most trusted OSs, with the exception of Linux, have the ability to specify static security labels for unlabeled networks. This patch adds this ability to the NetLabel packet labeling framework. If the NetLabel subsystem is called to determine the security attributes of an incoming packet it first checks to see if any recognized NetLabel packet labeling protocols are in-use on the packet. If none can be found then the unlabled connection table is queried and based on the packets incoming interface and address it is matched with a security label as configured by the administrator using the netlabel_tools package. The matching security label is returned to the caller just as if the packet was explicitly labeled using a labeling protocol.

* NetLabel: Add IP address family information to the netlbl_skbuff_getattr() ↵Paul Moore2008-01-29
| | | | | | | | | | | | function In order to do any sort of IP header inspection of incoming packets we need to know which address family, AF_INET/AF_INET6/etc., it belongs to and since the sk_buff structure does not store this information we need to pass along the address family separate from the packet itself.

* NetLabel: Add secid token support to the NetLabel secattr structPaul Moore2008-01-29
| | | | | | | | | | | This patch adds support to the NetLabel LSM secattr struct for a secid token and a type field, paving the way for full LSM/SELinux context support and "static" or "fallback" labels. In addition, this patch adds a fair amount of documentation to the core NetLabel structures used as part of the NetLabel kernel API.

* [NETNS]: Routing cache virtualization.Denis V. Lunev2008-01-28
| | | | | | | | | | | | Basically, this piece looks relatively easy. Namespace is already available on the dst entry via device and the device is safe to dereferrence. Compare it with one of a searcher and skip entry if appropriate. The only exception is ip_rt_frag_needed. So, add namespace parameter to it. Signed-off-by: Denis V.
