* [IPV4]: Use network-order dport for all visible inet_lookup_*Herbert Xu2006-09-221-5/+5
| | | | | | | | | | | | | | | | Right now most inet_lookup_* functions take a host-order hnum instead of a network-order dport because that's how it is represented internally. This means that users of these functions have to be careful about using the right byte-order. To add more confusion, inet_lookup takes a network-order dport unlike all other functions. So this patch changes all visible inet_lookup functions to take a dport and move all dport->hnum conversion inside them.

* [MLSXFRM]: Auto-labeling of child socketsVenkat Yekkirala2006-09-222-2/+8
| | | | | | | | | | | | | This automatically labels the TCP, Unix stream, and dccp child sockets as well as openreqs to be at the same MLS level as the peer. This will result in the selection of appropriately labeled IPSec Security Associations. This also uses the sock's sid (as opposed to the isec sid) in SELinux enforcement of secmark in rcv_skb and postroute_last hooks.

* [DCCP]: Fix CCID3Ian McDonald2006-08-276-193/+154
| | | | | | | | | | | | | | | | | | | | | | | | | This fixes CCID3 to give much closer performance to RFC4342. CCID3 is meant to alter sending rate based on RTT and loss. The performance was verified against: http://wand.net.nz/~perry/max_download.php For example I tested with netem and had the following parameters: Delayed Acks 1, MSS 256 bytes, RTT 105 ms, packet loss 5%. This gives a theoretical speed of 71.9 Kbits/s. I measured across three runs with this patch set and got 70.1 Kbits/s. Without this patchset the average was 232 Kbits/s which means Linux can't be used for CCID3 research properly. I also tested with netem turned off so box just acting as router with 1.2 msec RTT. The performance with this is the same with or without the patch at around 30 Mbit/s. Signed off by: Ian McDonald <ian.mcdonald@jandi.co.nz> Signed-off-by: David S. Miller <davem@davemloft.net>

* [IPV6]: Audit all ip6_dst_lookup/ip6_dst_store callsHerbert Xu2006-08-021-2/+2
| | | | | | | | | | | | | | | | | | | The current users of ip6_dst_lookup can be divided into two classes: 1) The caller holds no locks and is in user-context (UDP). 2) The caller does not want to lookup the dst cache at all. The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't. This patch adds __ip6_dst_store for those (everyone except UDP/datagram) that don't need an extra lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [DCCP]: Fix default sequence window sizeIan McDonald2006-07-244-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When using the default sequence window size (100) I got the following in my logs: Jun 22 14:24:09 localhost kernel: [ 1492.114775] DCCP: Step 6 failed for DATA packet, (LSWL(6279674225) <= P.seqno(6279674749) <= S.SWH(6279674324)) and (P.ackno doesn't exist or LAWL(18798206530) <= P.ackno(1125899906842620) <= S.AWH(18798206548), sending SYNC...

I went to alter the default sysctl and it didn't take for new sockets. Below patch fixes this. I think the default is too low but it is what the DCCP spec specifies. As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec to 3.5. This is still far too slow but it is a step in the right direction. Compile tested only for IPv6 but not particularly complex change.

* [DCCP]: Fix sock_orphan dead lockHerbert Xu2006-05-061-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling sock_orphan inside bh_lock_sock in dccp_close can lead to dead locks. For example, the inet_diag code holds sk_callback_lock without disabling BH. If an inbound packet arrives during that admittedly tiny window, it will cause a dead lock on bh_lock_sock. Another possible path would be through sock_wfree if the network device driver frees the tx skb in process context with BH enabled. We can fix this by moving sock_orphan out of bh_lock_sock. The tricky bit is to work out when we need to destroy the socket ourselves and when it has already been destroyed by someone else. By moving sock_orphan before the release_sock we can solve this problem. This is because as long as we own the socket lock its state cannot change. So we simply record the socket state before the release_sock and then check the state again after we regain the socket lock. If the socket state has transitioned to DCCP_CLOSED in the time being, we know that the socket has been destroyed. Otherwise the socket is still ours to keep. This problem was discoverd by Ingo Molnar using his lock validator. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi2006-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

Also the feature negotiation and option parsing code will mostly touch dccps_minisock, which will simplify some stuff.
