2006-01-03[IPVS]: Cleanup IP_VS_DBG statements.Roberto Nibali
From: Roberto Nibali <ratz@drugphish.ch> The attached patch (against current -GIT) is a cleanup patch which does following: o lookup debug messages shifted back to 9 o added more informational value to flags and refcnt since those entries can be in multiple referenced structures o cleanup 80 char violation It's the prepatch to the session pool implementation and helps very much to debug and monitor important variables and structures regarding the threshold limitation and persistency without the thousands of lookup messages which noone is interested in.

2005-11-29[NET]: Add const markers to various variables.Arjan van de Ven
the patch below marks various variables const in net/; the goal is to move them to the .rodata section so that they can't false-share cachelines with things that get written to, as well as potentially helping gcc a bit with optimisations.

2005-11-08[IPVS]: fix connection leak if expire_nodest_conn=1Julian Anastasov
There was a fix in 2.6.13 that changed the behaviour of ip_vs_conn_expire_now function not to put reference to connection, its callers should hold write lock or connection refcnt. But we forgot to convert one caller, when the real server for connection is unavailable caller should put the connection reference. It happens only when sysctl var expire_nodest_conn is set to 1 and such connections never expire. Thanks to Roberto Nibali who found the problem and tested a 2.4.32-rc2 patch, which is equal to this 2.6 version. Patch for 2.4 is already sent to Marcelo.

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-09-14[IPVS]: ip_vs_ftp breaks connections using persistenceJulian Anastasov
ip_vs_ftp when loaded can create NAT connections with unknown client port for passive FTP. For such expectations we lookup with cport=0 on incoming packet but it matches the format of the persistence templates causing packets to other persistent virtual servers to be forwarded to real server without creating connection. Later the reply packets are treated as foreign and not SNAT-ed. This patch changes the connection lookup for packets from clients: * introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the connection as template * create new connection lookup function just for templates - ip_vs_ct_in_get * make sure ip_vs_conn_in_get hits only connections with IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way we avoid returning template when looking for cport=0 (ftp) Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S. Miller <davem@davemloft.net>

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[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. Miller <davem@davemloft.net>
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!
