This requires just to pass the appropriate struct net pointer into __raw_v[46]_lookup and skip sockets that do not belong to a needed namespace. The proper net is get from skb->dev in all the cases. Signed-off-by:

If declared as unsigned short, these fields can overflow, and whole trie logic is broken. I could not make the machine crash, but some tnode can never be freed. Note for 64 bit arches : By reordering t_key and parent in [node, leaf, tnode] structures, we can use 32 bits hole after t_key so that sizeof(struct tnode) doesnt change after this patch.

alg_key_len is currently defined as 'signed int'. This unfortunatly leads to integer divides in several paths. Converting it to unsigned is safe and saves 208 bytes of text on i386. Signed-off-by:

In struct tnode, we use two fields of 5 bits for 'pos' and 'bits'. Switching to plain 'unsigned char' (8 bits) take the same space because of compiler alignments, and reduce text size by 435 bytes on i386.

Make FIB TRIE go through sparse checker without warnings. Signed-off-by:

Stephen Hemminger authored
The FIB TRIE code has a bunch of statistics, but the code is hidden behind an ifdef that was never implemented. Since it was dead code, it was broken as well. This patch fixes that by making it a config option. 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:

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:

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:

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:

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:
