Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[IPV4] FIB_HASH: Reduce memory needs and speedup lookups Currently, sizeof(struct fib_alias) is 24 or 48 bytes on 32/64 bits arches. Because of SLAB_HWCACHE_ALIGN requirement, these are rounded to 32 and 64 bytes respectively. This patch moves rcu to the end of fib_alias, and conditionally defines it only for CONFIG_IP_FIB_TRIE. We also remove SLAB_HWCACHE_ALIGN requirement for fib_alias and fib_node objects because it is not necessary. (BTW SLUB currently denies it for objects smaller than cache_line_size() / 2, but not SLAB) Finally, sizeof(fib_alias) go back to 16 and 32 bytes. Then, we can embed one fib_alias on each fib_node, to favor locality. Most of the time access to the fib_alias will be free because one cache line contains both the list head (fn_alias) and (one of) the list element.

[IPv4]: FIB configuration using struct fib_config Introduces struct fib_config replacing the ugly struct kern_rta prone to ordering issues. Avoids creating faked netlink messages for auto generated routes or requests via ioctl. A new interface net/nexthop.h is added to help navigate through nexthop configuration arrays. A new struct nl_info will be used to carry the necessary netlink information to be used for notifications later on. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

[NETLINK]: Correctly set NLM_F_MULTI without checking the pid This patch rectifies some rtnetlink message builders that derive the flags from the pid.
