The only error from fib_insert_node is if memory allocation fails, so instead of passing by reference, just use the convention of returning NULL. Signed-off-by:

trie_init is worthless it is just zeroing stuff that is already zero! Move the memset() down to make it obvious. Signed-off-by:

Still, the benefits are pretty obvious from the codiff's results. Signed-off-by:

When a new address is added, we must check if the new address does not already exists. This patch makes this check to be aware of a network namespace, so the check will look if the address already exists for the specified network namespace. While the addresses are browsed, the addresses which do not belong to the namespace are discarded. Signed-off-by:

When I studied the neighbor code I puzzled over what the NUD can mean for quite a long time. Finally I asked Alexey and he said that this was smth like "neighbor unreachability detection". Signed-off-by:

Otherwise we beat heavily on the global tcp_memory atomics when all of the sockets in the system are slowly sending perioding packet clumps. Noticed and suggested by Eric Dumazet. Signed-off-by: -

Actually the net->ipv6.devconf_all can be used in a few places, but to keep the /proc/sys/net/ipv6/conf/ sysctls work consistently in the namespace we should use the per-net devconf_all in the sysctl "forwarding" handler. Signed-off-by:
-
Pavel Emelyanov authored
All its users are in net/ipv6/addrconf.c's sysctl handlers. Since they already have the struct net to get from, the per-net ipv6_devconf_dflt can already be used. Signed-off-by:
-
Pavel Emelyanov authored
This is the core. Declare and register the pernet subsys for addrconf. The init callback the will create the devconf-s. The init_net will reuse the existing statically declared confs, so that accessing them from inside the ipv6 code will still work. The register_pernet_subsys() is moved above the ipv6_add_dev() call for loopback, because this function will need the net->devconf_dflt pointer to be already set. Signed-off-by:
-
Pavel Emelyanov authored
This includes passing the net to __addrconf_sysctl_register and saving this on the ctl_table->extra2 to be used in handlers (those, needing it). Signed-off-by:

This error code will be needed to abort the namespace creation if needed. Probably, this is to be checked when a new device is created (currently it is ignored). Signed-off-by:
-
Pavel Emelyanov authored
The addrconf sysctls and neigh sysctls are registered and unregistered always in pairs, so they can be joined into one (well, two) functions, that accept the struct inet6_dev and do all the job. This also get rids of unneeded ifdefs inside the code. Signed-off-by:

seq_open_net requires that first field of the seq->private data to be struct seq_net_private. In reality this is a single pointer to a struct net for now. The patch makes code consistent. Signed-off-by:

The iterator state->ns.neigh_sub_iter initialization is moved from arp_seq_open to clip_seq_start for convinience. This should not be a problem as the iterator will be used only after the seq_start callback. Signed-off-by:

cat /proc/net/atm/arp causes the NULL pointer dereference in the get_proc_net+0xc/0x3a. This happens as proc_get_net believes that the parent proc dir entry contains struct net. Fix this assumption for "net/atm" case. The problem is introduced by the commit c0097b07abf5f92ab135d024dd41bd2aada1512f from Eric W. Biederman/Daniel Lezcano. Signed-off-by:

nl_info is used to track the end-user destination of routing change notification. This is a natural object to hold a namespace on. Place it there and utilize the context in the appropriate places. Acked-by:

The patch extends the inet_addr_type and inet_dev_addr_type with the network namespace pointer. That allows to access the different tables relatively to the network namespace. The modification of the signature function is reported in all the callers of the inet_addr_type using the pointer to the well known init_net. Acked-by:

Replace the direct pointers to local and main tables with calls to fib_get_table() with appropriate argument. This doesn't introduce additional dereferences, but makes the access to fib tables uniform in any (CONFIG_IP_MULTIPLE_TABLES) case. Acked-by:
