ip6_dst_ops is dynamically allocated in init and exit functions. That provides the ability to do multiple instanciations of this structure. This will be needed for network namespaces, indeed dst_ops stores data that are required to be per namespace: entries and gc_thresh. Signed-off-by:

The rt6_info structures are moved inside the network namespace structure. All references to these structures are now relative to the initial network namespace. Signed-off-by:

This patch make mindless changes and prepares the code to use dynamic allocation for rt6_info structure. The code accesses the rt6_info structure as a pointer instead of a global static variable. Signed-off-by:

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. Signed-off-by:

Add a network namespace parameter to rt6_purge_dflt_routers. This is needed to call fib6_get_table with the appropriate network namespace. Signed-off-by:

Make /proc/net/ipv6_route and /proc/net/rt6_stats to be per namespace. These proc files are now created when the network namespace is initialized. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
-
Daniel Lezcano authored
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. Signed-off-by:

Daniel Lezcano authored
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. Signed-off-by:
-
Daniel Lezcano authored
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. Signed-off-by:

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. Signed-off-by:

Move the timer initialization at the network namespace creation and store the network namespace in the timer argument. That enables multiple timers (one per network namespace) to do garbage collecting. Signed-off-by:
-
Daniel Lezcano authored
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. Signed-off-by:
-
Daniel Lezcano authored
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:

The function fib6_clean_all takes the network namespace as parameter. That allows to flush the routes related to a specific network namespace. Signed-off-by:

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.

This patch changes the fib6 tables to be dynamically allocated. That provides the ability to make several instances of them when a new network namespace is created. Signed-off-by:

There are some place, that calculate the ARP header length. These calculations are correct, but a) some operate with "magic" constants, b) enlarge the code length (sometimes at the cost of coding style), c) are not informative from the first glance. The proposal is to introduce a helper, that includes all the good sides of these calculations. Signed-off-by:
