Get rid of the manual clock source selection mess and use ktime. Also use a scalar representation, which allows to clean up pkt_sched.h a bit more and results in less ktime_to_ns() calls in most cases. The PSCHED_US2JIFFIE/PSCHED_JIFFIE2US macros are implemented quite inefficient by this patch, following patches will convert all qdiscs to hrtimers and get rid of them entirely. Signed-off-by:

This time we have to set it to skb->tail that is not anymore equal to skb->data, so we either add a new helper or just add the skb->tail - skb->data offset, for now do the later. Signed-off-by:

ip6_nd_hdr is always called immediately after a alloc_skb + skb_reserve sequence, i.e. when skb->tail is equal to skb->data, making it correct to use skb_reset_network_header(). Signed-off-by:
-
Arnaldo Carvalho de Melo authored
This is similar to the skb_reset_network_header(), i.e. at the point we reset the transport header pointer/offset skb->tail is equal to skb->data. Signed-off-by:

Use nfattr_parse to parse attributes, this patch also modifies the default behaviour since unknown attributes will be ignored instead of returning EINVAL. This ensure backward compatibility: new libraries with new attributes and old kernels can work. Signed-off-by:

This patch let userspace programs set the IP_CT_TCP_BE_LIBERAL flag to force the pickup of established connections. Signed-off-by:

The PUSH flag is accepted with every other valid combination. Let's get it out of the tcp_valid_flags table and reduce the number of combinations we have to handle. This does not significantly reduce the table size however (8 bytes). Signed-off-by:

This combination has been encountered on an IBM AS/400 in response to packets sent to a closed session. There is no particular reason to mark it invalid. Signed-off-by:

This unifies the codes to copy netfilter related datas. Before copying, nf_copy() puts original members in destination skb. Signed-off-by:

This unifies the codes to copy netfilter related datas. Note that __nf_copy() assumes destination skb doesn't have any netfilter related members. Signed-off-by:

Now it uses jhash, but using jhash2 would be around 3-4 times faster (on P4). Signed-off-by:

Remove nfnetlink_check_attributes duplicates message size and callback id checks. nfnetlink_find_client and nfnetlink_rcv_msg already do such checks. Signed-off-by:

The retrying after an allocation failure is not necessary anymore since we're holding the mutex the entire time, for the same reason the double allocation race can't happen anymore. Signed-off-by:

Now that we don't use nf_conntrack_lock anymore but a single mutex for all protocol handling, no need to release and grab it again for sysctl registration. Signed-off-by:

Patrick McHardy authored
Remove ugly special-casing of nf_conntrack_l4proto_generic, all it wants is its sysctl tables registered, so do that explicitly in an init function and move the remaining protocol initialization and cleanup code to nf_conntrack_proto.c as well. Signed-off-by:
-
Patrick McHardy authored
The protocol lookups done by nf_conntrack are already protected by RCU, there is no need to keep taking nf_conntrack_lock for registration and unregistration. Switch to a mutex. Signed-off-by:

For the places where we need a pointer to the transport header, it is still legal to touch skb->h.raw directly if just adding to, subtracting from or setting it to another layer header. Signed-off-by:

These are a bit more subtle, they are of this type: - skb->h.raw = payload; __skb_pull(skb, payload - skb->data); + skb_reset_transport_header(skb); __skb_pull results in: skb->data = skb->data + payload - skb->data; skb->data = payload; So after __skb_pull we have skb->data pointing to payload and we can just call skb_reset_transport_header(skb), that will do: skb->h.raw = payload; The others are similar, allowing us to get rid of some more cases where a pointer was being attributed to the layer headers.
