* ipvs: provide default ip_vs_conn_{in,out}_get_protoSimon Horman2010-08-021-0/+12

* IPVS: make FTP work with full NAT supportHannes Eder2010-07-231-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | Use nf_conntrack/nf_nat code to do the packet mangling and the TCP sequence adjusting. The function 'ip_vs_skb_replace' is now dead code, so it is removed. To SNAT FTP, use something like: % iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 \ --vport 21 -j SNAT --to-source 192.168.10.10 and for the data connections in passive mode: % iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 \ --vportctl 21 -j SNAT --to-source 192.168.10.10 using '-m state --state RELATED' would also works. Make sure the kernel modules ip_vs_ftp, nf_conntrack_ftp, and nf_nat_ftp are loaded.

* IPVS: Allow boot time change of hash sizeCatalin(ux) M. BOIE2010-01-051-11/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was very frustrated about the fact that I have to recompile the kernel to change the hash size. So, I created this patch. If IPVS is built-in you can append ip_vs.conn_tab_bits=?? to kernel command line, or, if you built IPVS as modules, you can add options ip_vs conn_tab_bits=??. To keep everything backward compatible, you still can select the size at compile time, and that will be used as default. It has been about a year since this patch was originally posted and subsequently dropped on the basis of insufficient test data. Mark Bergsma has provided the following test results which seem to strongly support the need for larger hash table sizes: We do however run into the same problem with the default setting (212 = 4096 entries), as most of our LVS balancers handle around a million connections/SLAB entries at any point in time (around 100-150 kpps load). With only 4096 hash table entries this implies that each entry consists of a linked list of 256 connections *on average*. To provide some statistics, I did an oprofile run on an 2.6.31 kernel, with both the default 4096 table size, and the same kernel recompiled with IP_VS_CONN_TAB_BITS set to 18 (218 = 262144 entries). I built a quick test setup with a part of Wikimedia/Wikipedia's live traffic mirrored by the switch to the test host. With the default setting, at ~ 120 kpps packet load we saw a typical %si CPU usage of around 30-35%, and oprofile reported a hot spot in ip_vs_conn_in_get: samples % image name app name symbol name 1719761 42.3741 ip_vs.ko ip_vs.ko ip_vs_conn_in_get 302577 7.4554 bnx2 bnx2 /bnx2 181984 4.4840 vmlinux vmlinux __ticket_spin_lock 128636 3.1695 vmlinux vmlinux ip_route_input 74345 1.8318 ip_vs.ko ip_vs.ko ip_vs_conn_out_get 68482 1.6874 vmlinux vmlinux mwait_idle After loading the recompiled kernel with 218 entries, %si CPU usage dropped in half to around 12-18%, and oprofile looks much healthier, with only 7% spent in ip_vs_conn_in_get: samples % image name app name symbol name 265641 14.4616 bnx2 bnx2 /bnx2 143251 7.7986 vmlinux vmlinux __ticket_spin_lock 140661 7.6576 ip_vs.ko ip_vs.ko ip_vs_conn_in_get 94364 5.1372 vmlinux vmlinux mwait_idle 86267 4.6964 vmlinux vmlinux ip_route_input [ horms@verge.net.au: trivial up-port and minor style fixes ] Signed-off-by: Catalin(ux) M.

* ipvs: Embed estimator object into stats objectSven Wegener2008-08-111-2/+26
| | | | | | | | | | | | | | | There's no reason for dynamically allocating an estimator object for every stats object. Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

* [IPVS]: Synchronize closing of ConnectionsRumen G. Bogdanovski2007-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This patch makes the master daemon to sync the connection when it is about to close. This makes the connections on the backup to close or timeout according their state. Before the sync was performed only if the connection is in ESTABLISHED state which always made the connections to timeout in the hard coded 3 minutes. However the Andy Gospodarek's patch ([IPVS]: use proper timeout instead of fixed value) effectively did nothing more than increasing this to 15 minutes (Established state timeout). So this patch makes use of proper timeout since it syncs the connections on status changes to FIN_WAIT (2min timeout) and CLOSE (10sec timeout). However if the backup misses CLOSE hopefully it did not miss FIN_WAIT. Otherwise we will just have to wait for the ESTABLISHED state timeout. As it is without this patch. This way the number of the hanging connections on the backup is kept to minimum. And very few of them will be left to timeout with a long timeout. This is important if we want to make use of the fix for the real server overcommit on master/backup fail-over. Signed-off-by: Rumen G.

* [IPVS]: Bind connections on stanby if the destination existsRumen G. Bogdanovski2007-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the problem with node overload on director fail-over. Given the scenario: 2 nodes each accepting 3 connections at a time and 2 directors, director failover occurs when the nodes are fully loaded (6 connections to the cluster) in this case the new director will assign another 6 connections to the cluster, If the same real servers exist there. The problem turned to be in not binding the inherited connections to the real servers (destinations) on the backup director. Therefore: "ipvsadm -l" reports 0 connections: root@test2:~# ipvsadm -l IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP test2.local:5999 wlc -> node473.local:5999 Route 1000 0 0 -> node484.local:5999 Route 1000 0 0 while "ipvs -lnc" is right root@test2:~# ipvsadm -lnc IPVS connection entries pro expire state source virtual destination TCP 14:56 ESTABLISHED 192.168.0.10:39164 192.168.0.222:5999 192.168.0.51:5999 TCP 14:59 ESTABLISHED 192.168.0.10:39165 192.168.0.222:5999 192.168.0.52:5999 So the patch I am sending fixes the problem by binding the received connections to the appropriate service on the backup director, if it exists, else the connection will be handled the old way. So if the master and the backup directors are synchronized in terms of real services there will be no problem with server over-committing since new connections will not be created on the nonexistent real services on the backup. However if the service is created later on the backup, the binding will be performed when the next connection update is received. With this patch the inherited connections will show as inactive on the backup: root@test2:~# ipvsadm -l IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP test2.local:5999 wlc -> node473.local:5999 Route 1000 0 1 -> node484.local:5999 Route 1000 0 1 rumen@test2:~$ cat /proc/net/ip_vs IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP C0A800DE:176F wlc -> C0A80033:176F Route 1000 0 1 -> C0A80032:176F Route 1000 0 1 Regards, Rumen Bogdanovski Acked-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Rumen G.
