* [IPV6] XFRM: Fix connected socket to use transformation.Noriaki TAKAMIYA2007-10-111-0/+4
| | | | | | | | | | | | | | | | | | | | When XFRM policy and state are ready after TCP connection is started, the traffic should be transformed immediately, however it does not on IPv6 TCP. It depends on a dst cache replacement policy with connected socket. It seems that the replacement is always done for IPv4, however, on IPv6 case it is done only when routing cookie is changed. This patch fix that non-transformation dst can be changed to transformation one. This behavior is required by MIPv6 and improves IPv6 IPsec. Fixes by Masahide NAKAMURA.

* [IPV6]: Fix routing round-robin locking.David S. Miller2007-03-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per RFC2461, section 6.3.6, item #2, when no routers on the matching list are known to be reachable or probably reachable we do round robin on those available routes so that we make sure to probe as many of them as possible to detect when one becomes reachable faster. Each routing table has a rwlock protecting the tree and the linked list of routes at each leaf. The round robin code executes during lookup and thus with the rwlock taken as a reader. A small local spinlock tries to provide protection but this does not work at all for two reasons: 1) The round-robin list manipulation, as coded, goes like this (with read lock held): walk routes finding head and tail spin_lock(); rotate list using head and tail spin_unlock(); While one thread is rotating the list, another thread can end up with stale values of head and tail and then proceed to corrupt the list when it gets the lock. This ends up causing the OOPS in fib6_add() later onthat many people have been hitting. 2) All the other code paths that run with the rwlock held as a reader do not expect the list to change on them, they expect it to remain completely fixed while they hold the lock in that way. So, simply stated, it is impossible to implement this correctly using a manipulation of the list without violating the rwlock locking semantics. Reimplement using a per-fib6_node round-robin pointer. This way we don't need to manipulate the list at all, and since the round-robin pointer can only ever point to real existing entries we don't need to perform any locking on the changing of the round-robin pointer itself. We only need to reset the round-robin pointer to NULL when the entry it is pointing to is removed. The idea is from Thomas Graf and it is very similar to how this was implemented before the advanced router selection code when in. Signed-off-by: David S. Miller <davem@davemloft.net>

* [IPv6] route: FIB6 configuration using struct fib6_configThomas Graf2006-09-221-11/+27
| | | | | | | | | | | | | Replaces the struct in6_rtmsg based interface orignating from the ioctl interface with a struct fib6_config based on. Allows changing the interface without breaking the ioctl interface and avoids passing on tons of parameters. The recently introduced struct nl_info is used to pass on netlink authorship information for notifications. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

* [IPV6]: V6 route events reported with wrong netlink PID and seq numberJamal Hadi Salim2005-06-211-3/+6
| | | | | | | | | | | | | | | | | | | | | | | Essentially netlink at the moment always reports a pid and sequence of 0 always for v6 route activities. To understand the repurcassions of this look at: http://lists.quagga.net/pipermail/quagga-dev/2005-June/003507.html While fixing this, i took the liberty to resolve the outstanding issue of IPV6 routes inserted via ioctls to have the correct pids as well. This patch tries to behave as close as possible to the v4 routes i.e maintains whatever PID the socket issuing the command owns as opposed to the process. That made the patch a little bulky. I have tested against both netlink derived utility to add/del routes as well as ioctl derived one. The Quagga folks have tested against quagga. This fixes the problem and so far hasnt been detected to introduce any new issues.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+185
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
