| | | | | | | | | | Now that we use write_inode to flush server cache related to fid, we don't need tsyncfs either fort dotl or dotu protocols. For dotu this helps to do a more efficient server flush.

| * ipv4: Fix "Set rt->rt_iif more sanely on output routes."OGAWA Hirofumi2011-04-071-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1018b5c01636c7c6bda31a719bda34fc631db29a ("Set rt->rt_iif more sanely on output routes.") breaks rt_is_{output,input}_route. This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0". To fix it, this does: 1) Add "int rt_route_iif;" to struct rtable 2) For input routes, always set rt_route_iif to same value as rt_iif 3) For output routes, always set rt_route_iif to zero. Set rt_iif as it is done currently. 4) Change rt_is_{output,input}_route() to test rt_route_iif Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The description for buf_size was misleading and just said you couldn't TX larger aggregates, but of course you can't TX aggregates in a way that would exceed the window either, which is possible even if the aggregates are shorter than that.

* | | net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs2011-03-302-0/+24
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

* | xfrm: Assign esn pointers when cloning a stateSteffen Klassert2011-03-281-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | When we clone a xfrm state we have to assign the replay_esn and the preplay_esn pointers to the state if we use the new replay detection method. To this end, we add a xfrm_replay_clone() function that allocates memory for the replay detection and takes over the necessary values from the original state.

* | route: Take the right src and dst addresses in ip_route_newportsSteffen Klassert2011-03-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | When we set up the flow informations in ip_route_newports(), we take the address informations from the the rt_key_src and rt_key_dst fields of the rtable. They appear to be empty. So take the address informations from rt_src and rt_dst instead.

Since we want to avoid atomic ops in qdisc fast path - it was the meaning of commit 371121057607e (QDISC_STATE_RUNNING dont need atomic bit ops) - fix is to move THROTTLE bit into 'state' field, this one being manipulated with SMP and IRQ safe operations.

* | ipv4: fix route deletion for IPs on many subnetsJulian Anastasov2011-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alex Sidorenko reported for problems with local routes left after IP addresses are deleted. It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the estimator reading from estimation_timer to user context. ip_vs_read_estimator() will be used to decode the rate values. As the decoded rates are not set by estimation timer there is no need to reset them in ip_vs_zero_stats. There is no need ip_vs_new_estimator() to encode stats to rates, if the destination is in trash both the stats and the rates are inactive.

| | * | 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.

| | * | ipvs: reorganize tot_statsJulian Anastasov2011-03-151-2/+1

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove include/net/netns/ip_vs.h because it depends on structures from include/net/ip_vs.h. As ipvs is pointer in struct net it is better to move struct netns_ipvs into include/net/ip_vs.h, so that we can easily use other structures in struct netns_ipvs. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
