* tc: propogate errors from tcf_hash_createStephen Hemminger2008-11-261-2/+2
| | | | | | | Allow tcf_hash_create to return different errors on estimator failure. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* net_cls_act: act_simple dont ignore realloc codeJamal Hadi Salim2008-05-061-8/+9
| | | | | | | | reallocation of the policy data was being ignored. It could fail. Simplify so that there is no need for reallocating. Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
* net_cls_act: Make act_simple use of netlink policy.Jamal Hadi Salim2008-05-051-18/+16Star
| | | | | | | | Convert to netlink helpers by using netlink policy validation. As a side effect fixes a leak. Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
* [PKT_SCHED]: Fix datalen check in tcf_simp_init().Patrick McHardy2008-04-181-1/+1
| | | | | | | | | | datalen is unsigned so it can never be less than zero, but that's ok because the attribute passed to nla_len() has been validated and therefore a negative return value is impossible.

* [NET_SCHED]: Propagate nla_parse return valuePatrick McHardy2008-01-291-2/+6
| | | | | | | | nla_parse() returns more detailed errno codes, propagate them back on error. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo2007-04-261-1/+1
| | | | | | | | | | | | | | | So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

* [PKT_SCHED] act_simple.c: make struct simp_hash_info staticAdrian Bunk2006-09-231-1/+1

* [PKT_SCHED]: Kill pkt_act.h inlining.David S. Miller2006-09-221-31/+152
| | | | | | | | | | | | | | | | | | This was simply making templates of functions and mostly causing a lot of code duplication in the classifier action modules. We solve this more cleanly by having a common "struct tcf_common" that hash worker functions contained once in act_api.c can work with. Callers work with real action objects that have the common struct plus their module specific struct members. You go from a common object to the higher level one using a "to_foo()" macro which makes use of container_of() to do the dirty work. This also kills off act_generic.h which was only used by act_simple.c and keeping it around was more work than the it's value. Signed-off-by: David S. Miller <davem@davemloft.net>
