| * ip_vs.h: fix implicit use of module_get/module_put from module.hPaul Gortmaker2011-10-311-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This file was using the module get/put functions in two simple inline functions. But module_get/put were only within scope because of the implicit presence of module.h being everywhere. Rather than add module.h to another file in include/ -- which is exactly the thing we are trying to avoid, simply convert these one-line functions into a define, as per what was done for the device_schedule_callback() in commit 523ded71de0c5e669733.

* ipvs: Remove all remaining references to rt->rt_{src,dst}Julian Anastasov2011-05-121-5/+4
| | | | | | | | | | | | | | | Remove all remaining references to rt->rt_{src,dst} by using dest->dst_saddr to cache saddr (used for TUN mode). For ICMP in FORWARD hook just restrict the rt_mode for NAT to disable LOCALNODE. All other modes do not allow IP_VS_RT_MODE_RDR, so we should be safe with the ICMP forwarding. Using cp->daddr as replacement for rt_dst is safe for all modes except BYPASS, even when cp->dest is NULL because it is cp->daddr that is used to assign cp->dest for sync-ed connections.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DESCRIPTION This patch tries to restore the initial init and cleanup sequences that was before namspace patch. Netns also requires action when net devices unregister which has never been implemented. I.e this patch also covers when a device moves into a network namespace, and has to be released. IMPLEMENTATION The number of calls to register_pernet_device have been reduced to one for the ip_vs.ko Schedulers still have their own calls. This patch adds a function __ip_vs_service_cleanup() and an enable flag for the netfilter hooks. The nf hooks will be enabled when the first service is loaded and never disabled again, except when a namespace exit starts.

* IPVS: Use global mutex in ip_vs_app.cSimon Horman2011-03-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the work to make IPVS network namespace aware __ip_vs_app_mutex was replaced by a per-namespace lock, ipvs->app_mutex. ipvs->app_key is also supplied for debugging purposes. Unfortunately this implementation results in ipvs->app_key residing in non-static storage which at the very least causes a lockdep warning. This patch takes the rather heavy-handed approach of reinstating __ip_vs_app_mutex which will cover access to the ipvs->list_head of all network namespaces.

* ipvs: properly zero stats and ratesJulian Anastasov2011-03-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | The global tot_stats contains cpustats field just like the stats for dest and svc, so better use it to simplify the usage in estimation_timer. 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). Also, make sure ip_vs_stats_percpu_show reads properly the u64 stats from user context.

* ipvs: make "no destination available" message more informativePatrick Schaaf2011-02-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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: netns, connection hash got net as param.Hans Schillstrom2011-01-131-11/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | Connection hash table is now name space aware. i.e. net ptr >> 8 is xor:ed to the hash, and this is the first param to be compared. The net struct is 0xa40 in size ( a little bit smaller for 32 bit arch:s) and cache-line aligned, so a ptr >> 5 might be a more clever solution ? All lookups where net is compared uses net_eq() which returns 1 when netns is disabled, and the compiler seems to do something clever in that case. ip_vs_conn_fill_param() have *net as first param now. Three new inlines added to keep conn struct smaller when names space is disabled. - ip_vs_conn_net() - ip_vs_conn_net_set() - ip_vs_conn_net_eq() *v3 moved net compare to the end in "fast path" Signed-off-by: Hans Schillstrom <hans.schillstrom@ericsson.com> Acked-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The statistic counter locks for every packet are now removed, and that statistic is now per CPU, i.e. no locks needed. However summing is made in ip_vs_est into ip_vs_stats struct which is moved to ipvs struc. procfs, ip_vs_stats now have a "per cpu" count and a grand total. A new function seq_file_single_net() in ip_vs.h created for handling of single_open_net() since it does not place net ptr in a struct, like others. /var/lib/lxc # cat /proc/net/ip_vs_stats_percpu Total Incoming Outgoing Incoming Outgoing CPU Conns Packets Packets Bytes Bytes 0 0 3 1 9D 34 1 0 1 2 49 70 2 0 1 2 34 76 3 1 2 2 70 74 ~ 1 7 7 18A 18E Conns/s Pkts/s Pkts/s Bytes/s Bytes/s 0 0 0 0 0 *v3 ip_vs_stats reamains as before, instead ip_vs_stats_percpu is added. u64 seq lock added *v4 Bug correction inbytes and outbytes as own vars.. per_cpu counter for all stats now as suggested by Julian.

Two new inline functions added to get net ptr from skb.

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.
