2005-08-29[NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointersEric Dumazet
This patch puts mostly read only data in the right section (read_mostly), to help sharing of these data between CPUS without memory ping pongs. On one of my production machine, tcp_statistics was sitting in a heavily modified cache line, so *every* SNMP update had to force a reload.

2005-08-29[TCP]: Move the tcp sock states to net/tcp_states.hArnaldo Carvalho de Melo
Lots of places just needs the states, not even linux/tcp.h, where this enum was, needs it. This speeds up development of the refactorings as less sources are rebuilt when things get moved from net/tcp.h.

2005-08-29[NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte
As discussed at netconf'05, we're trying to save every bit in sk_buff. The patch below makes sk_buff 8 bytes smaller. I did some basic testing on my notebook and it seems to work. The only real in-tree user of nfcache was IPVS, who only needs a single bit. Unfortunately I couldn't find some other free bit in sk_buff to stuff that bit into, so I introduced a separate field for them. Maybe the IPVS guys can resolve that to further save space. Initially I wanted to shrink pkt_type to three bits (PACKET_HOST and alike are only 6 values defined), but unfortunately the bluetooth code overloads pkt_type :( The conntrack-event-api (out-of-tree) uses nfcache, but Rusty just came up with a way how to do it without any skb fields, so it's safe to remove it. - remove all never-implemented 'nfcache' code - don't have ipvs code abuse 'nfcache' field. currently get's their own compile-conditional skb->ipvs_property field. IPVS maintainers can decide to move this bit elswhere, but nfcache needs to die. - remove skb->nfcache field to save 4 bytes - move skb->nfctinfo into three unused bits to save further 4 bytes Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

2005-07-11[NET]: move config options out to individual protocolsSam Ravnborg
Move the protocol specific config options out to the specific protocols. With this change net/Kconfig now starts to become readable and serve as a good basis for further re-structuring. The menu structure is left almost intact, except that indention is fixed in most cases. Most visible are the INET changes where several "depends on INET" are replaced with a single ifdef INET / endif pair. Several new files were created to accomplish this change - they are small but serve the purpose that config options are now distributed out where they belongs.

2005-07-11[IPVS]: Add and reorder bh locks after moving to keventd.Julian Anastasov
An addition to the last ipvs changes that move update_defense_level/si_meminfo to keventd: - ip_vs_random_dropentry now runs in process context and should use _bh locks to protect from softirqs - update_defense_level still needs _bh locks after si_meminfo is called, for the same purpose Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.

2005-06-28[IPVS]: Close race conditions on ip_vs_conn_tab list modificationNeil Horman
In an smp system, it is possible for an connection timer to expire, calling ip_vs_conn_expire while the connection table is being flushed, before ct_write_lock_bh is acquired. Since the list iterator loop in ip_vs_con_flush releases and re-acquires the spinlock (even though it doesn't re-enable softirqs), it is possible for the expiration function to modify the connection list, while it is being traversed in ip_vs_conn_flush. The result is that the next pointer gets set to NULL, and subsequently dereferenced, resulting in an oops.

2005-06-26[IPVS]: Fix for overflowspageexec
From: <pageexec@freemail.hu> $subject was fixed in 2.4 already, 2.6 needs it as well. The impact of the bugs is a kernel stack overflow and privilege escalation from CAP_NET_ADMIN via the IP_VS_SO_SET_STARTDAEMON/IP_VS_SO_GET_DAEMON ioctls. People running with 'root=all caps' (i.e., most users) are not really affected (there's nothing to escalate), but SELinux and similar users should take it seriously if they grant CAP_NET_ADMIN to other users.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
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!
