2008-03-04[NETNS][IPV6] route6 - make route6 per namespaceDaniel Lezcano
This patch makes the routing engine use the network namespaces to access routing informations: Add a network namespace parameter to ipv6_route_ioctl and propagate the network namespace value to all the routing code that have not yet been changed.

2008-03-03[AF_KEY]: Dump SA/SP entries non-atomicallyTimo Teras
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.

2008-03-03[NETNS][IPV6] rt6_stats - make the stats per network namespaceBenjamin Thery
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.

2008-03-03[NETNS][IPV6] rt6_stats - dynamically allocate the routes statisticsDaniel Lezcano
This patch allocates the rt6_stats struct dynamically when the fib6 is initialized. That provides the ability to create several instances of this structure for the network namespaces.

2008-03-03[NETNS][IPV6] fib6_rules - handle several network namespacesDaniel Lezcano
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.

2008-03-03[NETNS][IPV6] fib6 rule - dynamic allocation of the rules struct opsDaniel Lezcano
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.

2008-03-03[NETNS][IPV6] ip6_fib - clean node use namespaceBenjamin Thery
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.

2008-03-03[NETNS][IPV6] ip6_fib - gc timer per namespaceDaniel Lezcano
Move the timer initialization at the network namespace creation and store the network namespace in the timer argument.

2008-03-03[NETNS][IPV6] ip6_fib - dynamically allocate gc-timerDaniel Lezcano
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. That will allow to make multiple instance of the garbage collecting timer and make them per namespace.

2008-03-03[NETNS][IPV6] ip6_fib - add net to gc timer parameterDaniel Lezcano
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.

The fib table for ipv6 are moved to the network namespace structure. All references to them are made relatively to the network namespace. 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.

2008-02-29mac80211: fix key replacing, hw accelJohannes Berg
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.

2008-02-29mac80211: split ieee80211_key_alloc/freeJohannes Berg
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>

2008-02-29mac80211: safely free beacon in ieee80211_if_reinitJohannes Berg
If ieee80211_if_reinit() is called from ieee80211_unregister_hw() then it is possible that the driver will still request a beacon (it is allowed to until ieee80211_unregister_hw() has returned.)

2008-02-29mac80211: Disallow concurrent IBSS/STA mode interfacesJohannes Berg
Disallow having more than one IBSS interface up at any time because of beacon distribution issues, and for now also disallow having more than one IBSS/STA interface up at the same time because we use the master interface's BSS struct which would be completely corrupted when we have more than one up.

2008-02-29mac80211: atomically check whether STA exists alreadyJohannes Berg
When a STA structure is added, it is often checked whether it already exists before adding it. This, however, isn't done atomically so there is a race condition that could lead to two STA structures being added with the same MAC address. This patch changes sta_info_add() to return an ERR_PTR in case of failure and adds the failure mode -EEXIST when the STA already exists.
