2011-02-17net: Add initial_ref arg to dst_alloc().David S. Miller
This allows avoiding multiple writes to the initial __refcnt. The most simplest cases of wanting an initial reference of "1" in ipv4 and ipv6 have been converted, the rest have been left along and kept at the existing "0". Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-11xfrm: check trunc_len in XFRMA_ALG_AUTH_TRUNCNicolas Dichtel
Maximum trunc length is defined by MAX_AH_AUTH_LEN (in bytes) and need to be checked when this value is set (in bits) by the user. In ah4.c and ah6.c a BUG_ON() checks this condiftion. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-01-10netlink: test for all flags of the NLM_F_DUMP compositeJan Engelhardt
Due to NLM_F_DUMP is composed of two bits, NLM_F_ROOT | NLM_F_MATCH, when doing "if (x & NLM_F_DUMP)", it tests for _either_ of the bits being set. Because NLM_F_MATCH's value overlaps with NLM_F_EXCL, non-dump requests with NLM_F_EXCL set are mistaken as dump requests. Substitute the condition to test for _all_ bits being set.

2010-12-14net: Abstract default MTU metric calculation behind an accessor.David S. Miller
Like RTAX_ADVMSS, make the default calculation go through a dst_ops method rather than caching the computation in the routing cache entries. Now dst metrics are pretty much left as-is when new entries are created, thus optimizing metric sharing becomes a real possibility. Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-13net: Abstract default ADVMSS behind an accessor.David S. Miller
Make all RTAX_ADVMSS metric accesses go through a new helper function, dst_metric_advmss(). Leave the actual default metric as "zero" in the real metric slot, and compute the actual default value dynamically via a new dst_ops AF specific callback. For stacked IPSEC routes, we use the advmss of the path which preserves existing behavior. Unlike ipv4/ipv6, DecNET ties the advmss to the mtu and thus updates advmss on pmtu updates. This inconsistency in advmss handling results in more raw metric accesses than I wish we ended up with. Signed-off-by: David S. Miller <davem@davemloft.net>

2010-12-10xfrm: Fix xfrm_state_migrate leakThomas Egerer
xfrm_state_migrate calls kfree instead of xfrm_state_put to free a failed state. According to git commit 553f9118 this can cause memory leaks.

2010-12-09net: Abstract away all dst_entry metrics accesses.David S. Miller
Use helper functions to hide all direct accesses, especially writes, to dst_entry metrics values. This will allow us to: 1) More easily change how the metrics are stored. 2) Implement COW for metrics. In particular this will help us put metrics into the inetpeer cache if that is what we end up doing. We can make the _metrics member a pointer instead of an array, initially have it point at the read-only metrics in the FIB, and then on the first set grab an inetpeer entry and point the _metrics member there.

2010-11-21net: allow GFP_HIGHMEM in __vmalloc()Eric Dumazet
We forgot to use __GFP_HIGHMEM in several __vmalloc() calls. In ceph, add the missing flag. In fib_trie.c, xfrm_hash.c and request_sock.c, using vzalloc() is cleaner and allows using HIGHMEM pages as well. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-09-20xfrm: Allow different selector family in temporary stateThomas Egerer
The family parameter xfrm_state_find is used to find a state matching a certain policy. This value is set to the template's family (encap_family) right before xfrm_state_find is called. The family parameter is however also used to construct a temporary state in xfrm_state_find itself which is wrong for inter-family scenarios because it produces a selector for the wrong family. Since this selector is included in the xfrm_user_acquire structure, user space programs misinterpret IPv6 addresses as IPv4 and vice versa. This patch splits up the original init_tempsel function into a part that initializes the selector respectively the props and id of the temporary state, to allow for differing ip address families whithin the state.
