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!

ipvs: Move userspace definitions to include/linux/ip_vs.h Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h" directly. This file also contains kernel-only definitions. Normally, public definitions should live in include/linux, so this patch moves the definitions shared with userspace to a new file, "include/linux/ip_vs.h". This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once used to point into skb->nfcache. To make old ipvsadms still compile with this, the old header file includes the new one. Thanks to Dave Miller and Horms for noting/adding the missing Kbuild entry for the new header file.

This is preparation to support ip_vs_out processing in LOCAL_OUT. ipvs_property=1 will be used to avoid expensive lookups for traffic sent by transmitters. Now when conntrack support is not used we call ip_vs_notrack method to avoid problems in OUTPUT and POST_ROUTING hooks instead of exiting POST_ROUTING as before.

ipvs: netfilter connection tracking changes Add more code to IPVS to work with Netfilter connection tracking and fix some problems. - Allow IPVS to be compiled without connection tracking as in 2.6.35 and before. This can avoid keeping conntracks for all IPVS connections because this costs memory. ip_vs_ftp still depends on connection tracking and NAT as implemented for 2.6.36. - Add sysctl var "conntrack" to enable connection tracking for all IPVS connections. For loaded IPVS directors it needs tuning of nf_conntrack_max limit. - Add IP_VS_CONN_F_NFCT connection flag to request the connection to use connection tracking. This allows user space to provide this flag, for example, in dest->conn_flags. This can be useful to request connection tracking per real server instead of forcing it for all connections with the "conntrack" sysctl. This flag is set currently only by ip_vs_ftp and of course by "conntrack" sysctl. - Add ip_vs_nfct.c file to hold all connection tracking code, by this way main code should not depend of netfilter conntrack support. - Return back the ip_vs_post_routing handler as in 2.6.35 and use skb->ipvs_property=1 to allow IPVS to work without connection tracking Connection tracking: - most of the code is already in 2.6.36-rc - alter conntrack reply tuple for LVS-NAT connections when first packet from client is forwarded and conntrack state is NEW or RELATED. Additionally, alter reply for RELATED connections from real server, again for packet in original direction. - add IP_VS_XMIT_TUNNEL to confirm conntrack (without altering reply) for LVS-TUN early because we want to call nf_reset. It is needed because we add IPIP header and the original conntrack should be preserved, not destroyed. The transmitted IPIP packets can reuse same conntrack, so we do not set skb->ipvs_property. - try to destroy conntrack when the IPVS connection is destroyed. It is not fatal if conntrack disappears before that, it depends on the used timers. Fix problems from long time: - add skb->ip_summed = CHECKSUM_NONE for the LVS-TUN transmitters Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Patrick McHardy <kaber@trash.net>

IPVS: Allow boot time change of hash size 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.

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.

ipvs: properly zero stats and rates Currently, the new percpu counters are not zeroed and the zero commands do not work as expected, we still show the old sum of percpu values. OTOH, we can not reset the percpu counters from user context without causing the incrementing to use old and bogus values. So, as Eric Dumazet suggested fix that by moving all overhead to stats reading in user context. Do not introduce overhead in timer context (estimator) and incrementing (packet handling in softirqs). The new ustats0 field holds the zero point for all counter values, the rates always use 0 as base value as before. When showing the values to user space just give the difference between counters and the base values. The only drawback is that percpu stats are not zeroed, they are accessible only from /proc and are new interface, so it should not be a compatibility problem as long as the sum stats are correct after zeroing.

[IPVS]: Synchronize closing of Connections 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: changes for local real server This patch deals with local real servers: - Add support for DNAT to local address (different real server port). It needs ip_vs_out hook in LOCAL_OUT for both families because skb->protocol is not set for locally generated packets and can not be used to set 'af'. - Skip packets in ip_vs_in marked with skb->ipvs_property because ip_vs_out processing can be executed in LOCAL_OUT but we still have the conn_out_get check in ip_vs_in. - Ignore packets with inet->nodefrag from local stack - Require skb_dst(skb) != NULL because we use it to get struct net - Add support for changing the route to local IPv4 stack after DNAT depending on the source address type. Local client sets output route and the remote client sets input route. It looks like IPv6 does not need such rerouting because the replies use addresses from initial incoming header, not from skb route. - All transmitters now have strict checks for the destination address type: redirect from non-local address to local real server requires NAT method, local address can not be used as source address when talking to remote real server. - Now LOCALNODE is not set explicitly as forwarding method in real server to allow the connections to provide correct forwarding method to the backup server. Not sure if this breaks tools that expect to see 'Local' real server type. If needed, this can be supported with new flag IP_VS_DEST_F_LOCAL. Now it should be possible connections in backup that lost their fwmark information during sync to be forwarded properly to their daddr, even if it is local address in the backup server. By this way backup could be used as real server for DR or TUN, for NAT there are some restrictions because tuple collisions in conntracks can create problems for the traffic. - Call ip_vs_dst_reset when destination is updated in case some real server IP type is changed between local and remote.

IPVS: netns to services part 1 Services hash tables got netns ptr a hash arg, While Real Servers (rs) has been moved to ipvs struct. Two new inline functions added to get net ptr from skb. Since ip_vs is called from different contexts there is two places to dig for the net ptr skb->dev or skb->sk this is handled in skb_net() and skb_sknet() Global functions, ip_vs_service_get() ip_vs_lookup_real_service() etc have got struct net *net as first param. If possible get net ptr skb etc, - if not &init_net is used at this early stage of patching. ip_vs_ctl.c procfs not ready for netns yet. *v3 Comments by Julian - __ip_vs_service_find and __ip_vs_svc_fwm_find are fast path, net_eq(svc->net, net) so the check is at the end now. - net = skb_net(skb) in ip_vs_out moved after check for skb_dst.

ipvs: IPv6 tunnel mode IPv6 encapsulation uses a bad source address for the tunnel. i.e. VIP will be used as local-addr and encap. dst addr. Decapsulation will not accept this. Example LVS (eth1 2003::2:0:1/96, VIP 2003::2:0:100) (eth0 2003::1:0:1/96) RS (ethX 2003::1:0:5/96) tcpdump 2003::2:0:100 > 2003::1:0:5: IP6 (hlim 63, next-header TCP (6) payload length: 40) 2003::3:0:10.50991 > 2003::2:0:100.http: Flags [S], cksum 0x7312 (correct), seq 3006460279, win 5760, options [mss 1440,sackOK,TS val 1904932 ecr 0,nop,wscale 3], length 0 In Linux IPv6 impl. you can't have a tunnel with an any cast address receiving packets (I have not tried to interpret RFC 2473) To have receive capabilities the tunnel must have: - Local address set as multicast addr or an unicast addr - Remote address set as an unicast addr. - Loop back addres or Link local address are not allowed. This causes us to setup a tunnel in the Real Server with the LVS as the remote address, here you can't use the VIP address since it's used inside the tunnel. Solution Use outgoing interface IPv6 address (match against the destination). i.e. use ip6_route_output() to look up the route cache and then use ipv6_dev_get_saddr(...) to set the source address of the encapsulated packet. Additionally, cache the results in new destination fields: dst_cookie and dst_saddr and properly check the returned dst from ip6_route_output. We now add xfrm_lookup call only for the tunneling method where the source address is a local one.

As tot_stats is registered as estimator we can remove the special ip_vs_read_cpu_stats call for tot_stats. Fix ip_vs_read_cpu_stats to be called under stats lock because it is still used as synchronization between estimation timer and user context (the stats readers).

ipvs: do not schedule conns from real servers This patch is needed to avoid scheduling of packets from local real server when we add ip_vs_in in LOCAL_OUT hook to support local client. Currently, when ip_vs_in can not find existing connection it tries to create new one by calling ip_vs_schedule. The default indication from ip_vs_schedule was if connection was scheduled to real server. If real server is not available we try to use the bypass forwarding method or to send ICMP error. But in some cases we do not want to use the bypass feature. So, add flag 'ignored' to indicate if the scheduler ignores this packet. Make sure we do not create new connections from replies. We can hit this problem for persistent services and local real server when ip_vs_in is added to LOCAL_OUT hook to handle local clients. Also, make sure ip_vs_schedule ignores SYN packets for Active FTP DATA from local real server. The FTP DATA connection should be created on SYN+ACK from client to assign correct connection daddr.

ipvs: make "no destination available" message more informative When IP_VS schedulers do not find a destination, they output a terse "WLC: no destination available" message through kernel syslog, which I can not only make sense of because syslog puts them in a logfile together with keepalived checker results. This patch makes the output a bit more informative, by telling you which virtual service failed to find a destination. Example output: kernel: [1539214.552233] IPVS: wlc: TCP 192.168.8.30:22 - no destination available kernel: [1539299.674418] IPVS: wlc: FWM 22 0x00000016 - no destination available I have tested the code for IPv4 and FWM services, as you can see from the example; I do not have an IPv6 setup to test the third code path with. To avoid code duplication, I put a new function ip_vs_scheduler_err() into ip_vs_sched.c, and use that from the schedulers instead of calling IP_VS_ERR_RL directly.

[IPVS]: Bind connections on stanby if the destination exists 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.

ipvs: netfilter connection tracking changes Add more code to IPVS to work with Netfilter connection tracking and fix some problems. - Allow IPVS to be compiled without connection tracking as in 2.6.35 and before. This can avoid keeping conntracks for all IPVS connections because this costs memory. ip_vs_ftp still depends on connection tracking and NAT as implemented for 2.6.36. - Add sysctl var "conntrack" to enable connection tracking for all IPVS connections. For loaded IPVS directors it needs tuning of nf_conntrack_max limit. - Add IP_VS_CONN_F_NFCT connection flag to request the connection to use connection tracking. This allows user space to provide this flag, for example, in dest->conn_flags. This can be useful to request connection tracking per real server instead of forcing it for all connections with the "conntrack" sysctl. This flag is set currently only by ip_vs_ftp and of course by "conntrack" sysctl. - Add ip_vs_nfct.c file to hold all connection tracking code, by this way main code should not depend of netfilter conntrack support. - Return back the ip_vs_post_routing handler as in 2.6.35 and use skb->ipvs_property=1 to allow IPVS to work without connection tracking Connection tracking: - most of the code is already in 2.6.36-rc - alter conntrack reply tuple for LVS-NAT connections when first packet from client is forwarded and conntrack state is NEW or RELATED. Additionally, alter reply for RELATED connections from real server, again for packet in original direction. - add IP_VS_XMIT_TUNNEL to confirm conntrack (without altering reply) for LVS-TUN early because we want to call nf_reset. It is needed because we add IPIP header and the original conntrack should be preserved, not destroyed.

ipvs: netfilter connection tracking changes Add more code to IPVS to work with Netfilter connection tracking and fix some problems. - Allow IPVS to be compiled without connection tracking as in 2.6.35 and before. This can avoid keeping conntracks for all IPVS connections because this costs memory. ip_vs_ftp still depends on connection tracking and NAT as implemented for 2.6.36. - Add sysctl var "conntrack" to enable connection tracking for all IPVS connections. For loaded IPVS directors it needs tuning of nf_conntrack_max limit. - Add IP_VS_CONN_F_NFCT connection flag to request the connection to use connection tracking. This allows user space to provide this flag, for example, in dest->conn_flags. This can be useful to request connection tracking per real server instead of forcing it for all connections with the "conntrack" sysctl. This flag is set currently only by ip_vs_ftp and of course by "conntrack" sysctl. - Add ip_vs_nfct.c file to hold all connection tracking code, by this way main code should not depend of netfilter conntrack support. - Return back the ip_vs_post_routing handler as in 2.6.35 and use skb->ipvs_property=1 to allow IPVS to work without connection tracking Connection tracking: - most of the code is already in 2.6.36-rc - alter conntrack reply tuple for LVS-NAT connections when first packet from client is forwarded and conntrack state is NEW or RELATED. Additionally, alter reply for RELATED connections from real server, again for packet in original direction. - add IP_VS_XMIT_TUNNEL to confirm conntrack (without altering reply) for LVS-TUN early because we want to call nf_reset. It is needed because we add IPIP header and the original conntrack should be preserved, not destroyed. The transmitted IPIP packets can reuse same conntrack, so we do not set skb->ipvs_property. - try to destroy conntrack when the IPVS connection is destroyed.

ipvs: fix active FTP - Do not create expectation when forwarding the PORT command to avoid blocking the connection. The problem is that nf_conntrack_ftp.c:help() tries to create the same expectation later in POST_ROUTING and drops the packet with "dropping packet" message after failure in nf_ct_expect_related. - Change ip_vs_update_conntrack to alter the conntrack for related connections from real server. If we do not alter the reply in this direction the next packet from client sent to vport 20 comes as NEW connection. We alter it but may be some collision happens for both conntracks and the second conntrack gets destroyed immediately. The connection stucks too.

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!

ipvs: Move userspace definitions to include/linux/ip_vs.h Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h" directly. This file also contains kernel-only definitions. Normally, public definitions should live in include/linux, so this patch moves the definitions shared with userspace to a new file, "include/linux/ip_vs.h". This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once used to point into skb->nfcache. To make old ipvsadms still compile with this, the old header file includes the new one. Thanks to Dave Miller and Horms for noting/adding the missing Kbuild entry for the new header file.
