| * ipconfig: Handle devices which take some time to come up.David S. Miller2010-03-121-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some network devices, particularly USB ones, take several seconds to fully init and appear in the device list. If the user turned ipconfig on, they are using it for NFS root or some other early booting purpose. So it makes no sense to just flat out fail immediately if the device isn't found. It also doesn't make sense to just jack up the initial wait to something crazy like 10 seconds. Instead, poll immediately, and then periodically once a second, waiting for a usable device to appear. Fail after 12 seconds. Signed-off-by: David S. Miller <davem@davemloft.net> Tested-by: Christian Pellegrin <chripell@fsfe.org>

| * net: fix route cache rebuildsEric Dumazet2010-03-081-12/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added an automatic route cache rebuilding in commit 1080d709fb9d8cd43 but had to correct few bugs. One of the assumption of original patch, was that entries where kept sorted in a given way. This assumption is known to be wrong (commit 1ddbcb005c395518 gave an explanation of this and corrected a leak) and expensive to respect. Paweł Staszewski reported to me one of his machine got its routing cache disabled after few messages like : [ 2677.850065] Route hash chain too long! [ 2677.850080] Adjust your secret_interval! [82839.662993] Route hash chain too long! [82839.662996] Adjust your secret_interval! [155843.731650] Route hash chain too long! [155843.731664] Adjust your secret_interval! [155843.811881] Route hash chain too long! [155843.811891] Adjust your secret_interval! [155843.858209] vlan0811: 5 rebuilds is over limit, route caching disabled [155843.858212] Route hash chain too long! [155843.858213] Adjust your secret_interval! This is because rt_intern_hash() might be fooled when computing a chain length, because multiple entries with same keys can differ because of TOS (or mark/oif) bits. In the rare case the fast algorithm see a too long chain, and before taking expensive path, we call a helper function in order to not count duplicates of same routes, that only differ with tos/mark/oif bits. This helper works with data already in cpu cache and is not be very expensive, despite its O(N^2) implementation. Paweł Staszewski sucessfully tested this patch on his loaded router.

| * gre: fix hard header destination address checkingTimo Teräs2010-03-041-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipgre_header() can be called with zero daddr when the gre device is configured as multipoint tunnel and still has the NOARP flag set (which is typically cleared by the userspace arp daemon). If the NOARP packets are not dropped, ipgre_tunnel_xmit() will take rt->rt_gateway (= NBMA IP) and use that for route look up (and may lead to bogus xfrm acquires). The multicast address check is removed as sending to multicast group should be ok. In fact, if gre device has a multicast address as destination ipgre_header is always called with multicast address.

| * ipsec: Fix bogus bundle flowiHerbert Xu2010-03-031-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I merged the bundle creation code, I introduced a bogus flowi value in the bundle. Instead of getting from the caller, it was instead set to the flow in the route object, which is totally different. The end result is that the bundles we created never match, and we instead end up with an ever growing bundle list. Thanks to Jamal for find this problem.

The rcu_dereference() in __sk_free() is protected by the fact that it is never reached if an update could change it. Check for this by using rcu_dereference_check() to verify that the struct sock's ->sk_wmem_alloc counter is zero. Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: David S.

It turns out that when we restart sysctls we were restarting with the values already changed. Which unfortunately meant that the second time through we thought there was no change and skipped all kinds of work, despite the fact that there was indeed a change. I have fixed this the simplest way possible by restoring the changed values when we restart the sysctl write.

| * | | netfilter: nf_nat: support mangling a single TCP packet multiple timesPatrick McHardy2010-02-111-16/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nf_nat_mangle_tcp_packet() can currently only handle a single mangling per window because it only maintains two sequence adjustment positions: the one before the last adjustment and the one after. This patch makes sequence number adjustment tracking in nf_nat_mangle_tcp_packet() optional and allows a helper to manually update the offsets after the packet has been fully handled.

| * | | netfilter: nf_conntrack_sip: add TCP supportPatrick McHardy2010-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add TCP support, which is mandated by RFC3261 for all SIP elements. SIP over TCP is similar to UDP, except that messages are delimited by Content-Length: headers and multiple messages may appear in one packet. Signed-off-by: Patrick McHardy <kaber@trash.net>
| * | | netfilter: nf_conntrack_sip: pass data offset to NAT functionsPatrick McHardy2010-02-111-50/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using TCP multiple SIP messages might be present in a single packet. A following patch will parse them by setting the dptr to the beginning of each message. The NAT helper needs to reload the dptr value after mangling the packet however, so it needs to know the offset of the message to the beginning of the packet.

| * | | netfilter: xtables: generate initial table on-demandJan Engelhardt2010-02-108-199/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The static initial tables are pretty large, and after the net namespace has been instantiated, they just hang around for nothing. This commit removes them and creates tables on-demand at runtime when needed. Size shrinks by 7735 bytes (x86_64). Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
