2005-08-29[CCID3]: Separate most of the packet history codeArnaldo Carvalho de Melo
This also changes the list_for_each_entry_safe_continue behaviour to match its kerneldoc comment, that is, to start after the pos passed. Also adds several helper functions from previously open coded fragments, making the code more clear. Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
2005-08-29[TCPDIAG]: Implement cheapest way of supporting DCCPDIAG_GETSOCKArnaldo Carvalho de Melo
With ugly ifdefs, etc, but this actually: 1. keeps the existing ABI, i.e. no need to recompile the iproute2 utilities if not interested in DCCP. 2. Provides all the tcp_diag functionality in DCCP, with just a small patch that makes iproute2 support DCCP. Of course I'll get this cleaned-up in time, but for now I think its OK to be this way to quickly get this functionality. iproute2-ss050808 patch at: http://vger.kernel.org/~acme/iproute2-ss050808.dccp.patch Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

2005-08-29[ICSK]: Move TCP congestion avoidance members to icskArnaldo Carvalho de Melo
This changeset basically moves tcp_sk()->{ca_ops,ca_state,etc} to inet_csk(), minimal renaming/moving done in this changeset to ease review. Most of it is just changes of struct tcp_sock * to struct sock * parameters. With this we move to a state closer to two interesting goals: 1. Generalisation of net/ipv4/tcp_diag.c, becoming inet_diag.c, being used for any INET transport protocol that has struct inet_hashinfo and are derived from struct inet_connection_sock. Keeps the userspace API, that will just not display DCCP sockets, while newer versions of tools can support DCCP. 2. INET generic transport pluggable Congestion Avoidance infrastructure, using the current TCP CA infrastructure with DCCP.

That groups all of the tables and variables associated to the TCP timewait schedulling/recycling/killing code, that now can be isolated from the TCP specific code and used by other transport protocols, such as DCCP.

2005-08-29[NETFILTER]: New iptables DCCP protocol header matchHarald Welte

2005-08-29[DCCP]: make <linux/dccp.h> include-able from userspaceHarald Welte
The protocol header files in <linux/foo.h> are usually structured in a way to be included by userspace code. The top section consists of general protocol structure definitions, typedefs, enums - followed by an #ifdef __KERNEL__ section. Currently <linux/dccp.h> doesn't follow that convention and can therefore not be used from userspace. However, for example iptables' libipt_dccp.c actually needs various definitions from there.

2005-08-29[NETFILTER]: add /proc/net/netfilter interface to nf_queueHarald Welte
This patch adds a /proc/net/netfilter/nf_queue file, similar to the recently-added /proc/net/netfilter/nf_log. It indicates which queue handler is registered to which protocol family. This is useful since there are now multiple queue handlers in the treee (ip[6]_queue, nfnetlink_queue). Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

2005-08-29[NETFILTER]: add correct bridging support to nfnetlink_{queue,log}Harald Welte
This patch adds support for passing the real 'physical' device ifindex down to userspace via nfnetlink_log and nfnetlink_queue. This feature basically obsoletes net/bridge/netfilter/ebt_ulog.c, and it is likely ebt_ulog.c will die with one of the next couple of patches.

2005-08-29[ICSK]: Move generalised functions from tcp to inet_connection_sockArnaldo Carvalho de Melo
This also improves reqsk_queue_prune and renames it to inet_csk_reqsk_queue_prune, as it deals with both inet_connection_sock and inet_request_sock objects, not just with request_sock ones thus belonging to inet_request_sock.

2005-08-29[NET]: Introduce inet_connection_sockArnaldo Carvalho de Melo
This creates struct inet_connection_sock, moving members out of struct tcp_sock that are shareable with other INET connection oriented protocols, such as DCCP, that in my private tree already uses most of these members. The functions that operate on these members were renamed, using a inet_csk_ prefix while not being moved yet to a new file, so as to ease the review of these changes.

2005-08-29[INET]: Generalise tcp_tw_bucket, aka TIME_WAIT socketsArnaldo Carvalho de Melo
This paves the way to generalise the rest of the sock ID lookup routines and saves some bytes in TCPv4 TIME_WAIT sockets on distro kernels (where IPv6 is always built as a module): [root@qemu ~]# grep tw_sock /proc/slabinfo tw_sock_TCPv6 0 0 128 31 1 tw_sock_TCP 0 0 96 41 1 [root@qemu ~]# Now if a protocol wants to use the TIME_WAIT generic infrastructure it only has to set the sk_prot->twsk_obj_size field with the size of its inet_timewait_sock derived sock and proto_register will create sk_prot->twsk_slab, for now its only for INET sockets, but we can introduce timewait_sock later if some non INET transport protocolo wants to use this stuff. Next changesets will take advantage of this new infrastructure to generalise even more TCP code.

2005-08-29[INET]: Generalise tcp_v4_hash & tcp_unhashArnaldo Carvalho de Melo
It really just makes the existing code be a helper function that tcp_v4_hash and tcp_unhash uses, specifying the right inet_hashinfo, tcp_hashinfo. One thing I'll investigate at some point is to have the inet_hashinfo pointer in sk_prot, so that we get all the hashtable information from the sk pointer, this can lead to some extra indirections that may well hurt performance/code size, we'll see. Ultimate idea would be that sk_prot would provide _all_ the information about a protocol implementation. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[TCP]: Move the tcp sock states to net/tcp_states.hArnaldo Carvalho de Melo
Lots of places just needs the states, not even linux/tcp.h, where this enum was, needs it.

2005-08-29[NETFILTER]: don't use nested attributes for conntrack_expectHarald Welte
We used to use nested nfattr structures for ip_conntrack_expect. This is bogus, since ip_conntrack and ip_conntrack_expect are communicated in different netlink message types. both should be encoded at the top level attributes, no extra nesting required. This patch addresses the issue. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NETFILTER]: attribute count is an attribute of message type, not subsytemHarald Welte
Prior to this patch, every nfnetlink subsystem had to specify it's attribute count. However, in reality the attribute count depends on the message type within the subsystem, not the subsystem itself. This patch moves 'attr_count' from 'struct nfnetlink_subsys' into nfnl_callback to fix this. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NETFILTER]: Fix multiple problems with the conntrack event cachePatrick McHardy
refcnt underflow: the reference count is decremented when a conntrack entry is removed from the hash but it is not incremented when entering new entries. missing protection of process context against softirq context: all cache operations need to locally disable softirqs to avoid races. Additionally the event cache can't be initialized when a packet enteres the conntrack code but needs to be initialized whenever we cache an event and the stored conntrack entry doesn't match the current one. incorrect flushing of the event cache in ip_ct_iterate_cleanup: without real locking we can't flush the cache for different CPUs without incurring races. The cache for different CPUs can only be flushed when no packets are going through the code. ip_ct_iterate_cleanup doesn't need to drop all references, so flushing is moved to the cleanup path.

2005-08-29[INET]: Move bind_hash from tcp_sk to inet_skArnaldo Carvalho de Melo
This should really be in a inet_connection_sock, but I'm leaving it for a later optimization, when some more fields common to INET transport protocols now in tcp_sk or inet_sk will be chunked out into inet_connection_sock, for now its better to concentrate on getting the changes in the core merged to leave the DCCP tree with only DCCP specific code. Next changesets will take advantage of this move to generalise things like tcp_bind_hash, tcp_put_port, tcp_inherit_port, making the later receive a inet_hashinfo parameter, and even __tcp_tw_hashdance, etc in the future, when tcp_tw_bucket gets transformed into the struct timewait_sock hierarchy. tcp_destroy_sock also is eligible as soon as tcp_orphan_count gets moved to sk_prot. A cascade of incremental changes will ultimately make the tcp_lookup functions be fully generic. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S.

2005-08-29[INET]: Just rename the TCP hashtable functions/structs to inet_Arnaldo Carvalho de Melo
This is to break down the complexity of the series of patches, making it very clear that this one just does: 1. renames tcp_ prefixed hashtable functions and data structures that were already mostly generic to inet_ to share it with DCCP and other INET transport protocols. 2. Removes not used functions (__tb_head & tb_head) 3. Removes some leftover prototypes in the headers (tcp_bucket_unlock & tcp_v4_build_header) Next changesets will move tcp_sk(sk)->bind_hash to inet_sock so that we can make functions such as tcp_inherit_port, __tcp_inherit_port, tcp_v4_get_port, __tcp_put_port, generic and get others like tcp_destroy_sock closer to generic (tcp_orphan_count will go to sk->sk_prot to allow this). Eventually most of these functions will be used passing the transport protocol inet_hashinfo structure. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> Signed-off-by: David S.
