* [AF_KEY]: Dump SA/SP entries non-atomicallyTimo Teras2008-03-04
| | | | | | | | | | | | Stop dumping of entries when af_key socket receive queue is getting full and continue it later when there is more room again. This fixes dumping of large databases. Currently the entries not fitting into the receive queue are just dropped (including the end-of-dump message) which can confuse applications.

* [NETNS][IPV6] rt6_stats - make the stats per network namespaceBenjamin Thery2008-03-04
| | | | | | | | | | The rt6_stats is now per namespace with this patch. It is allocated when a network namespace is created and freed when the network namespace exits and references are relative to the network namespace.

* [NETNS][IPV6] rt6_stats - dynamically allocate the routes statisticsDaniel Lezcano2008-03-04

* [NETNS][IPV6] fib6_rules - handle several network namespacesDaniel Lezcano2008-03-04
| | | | | | | | | | | | | | | | | The fib6_rules_ops is moved to the network namespace structure. All references are changed to have it relatively to it. Each time a network namespace is created a new fib6_rules_ops is allocated, initialized and stored into the network namespace structure. The common part of the fib rules is namespace aware, so it is quite easy to retrieve the network namespace from the rules and use it in the different callbacks.

| | | | | | | | | | | | | The fib6_rules_ops structure is dynamically allocated, so that allows to make several instances of it per network namespace. The global static fib6_rules_ops structure is renamed to fib6_rules_ops_template in order to quickly memcopy it for the structure initialization.

| | | | | | | | | | | | | | The fib6_clean_node function should have the network namespace it is working on. The fib6_cleaner_t structure is extended with the network namespace field to be passed to the fib6_clean_node function. The different functions calling the fib6_clean_node function are extended with the netns parameter when needed to propagate the netns pointer.

* [NETNS][IPV6] ip6_fib - dynamically allocate gc-timerDaniel Lezcano2008-03-04
| | | | | | | | | | | The ip6_fib_timer gc timer is dynamically allocated and initialized in the ip6 fib init function. There are no more references to a static global variable.

* [NETNS][IPV6] ip6_fib - add net to gc timer parameterDaniel Lezcano2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | The fib tables are now relative to the network namespace. When the garbage collector timer expires, we must have a network namespace parameter in order to retrieve the tables. For now this is the init_net, but we should be able to have a timer per namespace and use the timer callback parameter to pass the network namespace from the expired timer. The timer callback, fib6_run_gc, is actually used to be called synchronously by some functions and asynchronously when the timer expires. When the timer expires, the delay specified for fib6_run_gc parameter is always zero. So, I changed fib6_run_gc to not be a timer callback but a function called by the timer callback and I added a timer callback where its work is just to retrieve from the data arg of the timer the network namespace and call fib6_run_gc with zero expiring time and the network namespace parameters. That makes the code cleaner for the fib6_run_gc callers. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S.

All external calls to the ip6_fib functions taking the network namespace parameter are made using the init_net variable, so the ip6_fib engine is ready for the namespaces but the callers not yet.

| * mac80211: fix key replacing, hw accelJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though I thought about it a lot and had also tested it, some of my recent changes in the key code broke replacing keys, making the kernel oops because a key is removed from a list while not on it. This patch fixes that using the list as an indication whether or not the key is on it (an empty list means it's not on any list.) Also, this patch fixes hw accel enabling, the check for not doing hw accel when the interface is down was lost and is restored by this. Additionally, move adding the key to the list into the function __ieee80211_key_replace() for more consistency. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * mac80211: split ieee80211_key_alloc/freeJohannes Berg2008-02-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to RCU-ify sta_info, we need to be able to allocate a key without linking it to an sdata/sta structure (because allocation cannot be done in an rcu critical section). This patch splits up ieee80211_key_alloc() and updates all users appropriately. While at it, this patch fixes a number of race conditions such as finally making key replacement atomic, unfortunately at the expense of more complex code. Note that this patch documents /existing/ bugs with sta info and key interaction, there is currently a race condition when a sta info is freed without holding the RTNL. This will finally be fixed by a followup patch. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
