* net: ipv6: fix oops in inet_putpeer()Patrick McHardy2012-08-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 97bab73f (inet: Hide route peer accesses behind helpers.) introduced a bug in xfrm6_policy_destroy(). The xfrm_dst's _rt6i_peer member is not initialized, causing a false positive result from inetpeer_ptr_is_peer(), which in turn causes a NULL pointer dereference in inet_putpeer().

* net: Pass optional SKB and SK arguments to dst_ops->{update_pmtu,redirect}()David S. Miller2012-07-171-4/+6
| | | | | | | | | | | | | | | | This will be used so that we can compose a full flow key. Even though we have a route in this context, we need more. In the future the routes will be without destination address, source address, etc. keying. One ipv4 route will cover entire subnets, etc. In this environment we have to have a way to possess persistent storage for redirects and PMTU information. This persistent storage will exist in the FIB tables, and that's why we'll need to be able to rebuild a full lookup flow key here. Using that flow key will do a fib_lookup() and create/update the persistent entry. Signed-off-by: David S. Miller <davem@davemloft.net>

* net: Implement read-only protection and COW'ing of metrics.David S. Miller2011-01-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Routing metrics are now copy-on-write. Initially a route entry points it's metrics at a read-only location. If a routing table entry exists, it will point there. Else it will point at the all zero metric place-holder called 'dst_default_metrics'. The writeability state of the metrics is stored in the low bits of the metrics pointer, we have two bits left to spare if we want to store more states. For the initial implementation, COW is implemented simply via kmalloc. However future enhancements will change this to place the writable metrics somewhere else, in order to increase sharing. Very likely this "somewhere else" will be the inetpeer cache. Note also that this means that metrics updates may transiently fail if we cannot COW the metrics successfully. But even by itself, this patch should decrease memory usage and increase cache locality especially for routing workloads. In those cases the read-only metric copies stay in place and never get written to. TCP workloads where metrics get updated, and those rare cases where PMTU triggers occur, will take a very slight performance hit. But that hit will be alleviated when the long-term writable metrics move to a more sharable location. Since the metrics storage went from a u32 array of RTAX_MAX entries to what is essentially a pointer, some retooling of the dst_entry layout was necessary. Most importantly, we need to preserve the alignment of the reference count so that it doesn't share cache lines with the read-mostly state, as per Eric Dumazet's alignment assertion checks. The only non-trivial bit here is the move of the 'flags' member into the writeable cacheline. This is OK since we are always accessing the flags around the same moment when we made a modification to the reference count. Signed-off-by: David S. Miller <davem@davemloft.net>

* | xfrm: cache bundles instead of policies for outgoing flowsTimo Teräs2010-04-071-31/+0
|/ | | | | | | | | | | | | | | __xfrm_lookup() is called for each packet transmitted out of system. The xfrm_find_bundle() does a linear search which can kill system performance depending on how many bundles are required per policy. This modifies __xfrm_lookup() to store bundles directly in the flow cache. If we did not get a hit, we just create a new bundle instead of doing slow search. This means that we can now get multiple xfrm_dst's for same flow (on per-cpu basis). Signed-off-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipsec: Fix bogus bundle flowiHerbert Xu2010-03-031-1/+2

Instead of getting from the caller, it was instead set to the flow in the route object, which is totally different.

* xfrm: select sane defaults for xfrm[4|6] gc_threshNeil Horman2009-07-301-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Choose saner defaults for xfrm[4|6] gc_thresh values on init Currently, the xfrm[4|6] code has hard-coded initial gc_thresh values (set to 1024). Given that the ipv4 and ipv6 routing caches are sized dynamically at boot time, the static selections can be non-sensical. This patch dynamically selects an appropriate gc threshold based on the corresponding main routing table size, using the assumption that we should in the worst case be able to handle as many connections as the routing table can. For ipv4, the maximum route cache size is 16 * the number of hash buckets in the route cache. Given that xfrm4 starts garbage collection at the gc_thresh and prevents new allocations at 2 * gc_thresh, we set gc_thresh to half the maximum route cache size. For ipv6, its a bit trickier. there is no maximum route cache size, but the ipv6 dst_ops gc_thresh is statically set to 1024. It seems sane to select a simmilar gc_thresh for the xfrm6 code that is half the number of hash buckets in the v6 route cache times 16 (like the v4 code does).

* xfrm: export xfrm garbage collector thresholds via sysctlNeil Horman2009-07-271-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Export garbage collector thresholds for xfrm[4|6]_dst_ops Had a problem reported to me recently in which a high volume of ipsec connections on a system began reporting ENOBUFS for new connections eventually. It seemed that after about 2000 connections we started being unable to create more. A quick look revealed that the xfrm code used a dst_ops structure that limited the gc_thresh value to 1024, and always dropped route cache entries after 2x the gc_thresh. It seems the most direct solution is to export the gc_thresh values in the xfrm[4|6] dst_ops as sysctls, like the main routing table does, so that higher volumes of connections can be supported. This patch has been tested and allows the reporter to increase their ipsec connection volume successfully.
