q->now is increased during dequeue and doesn't contain the current time afterwards, resulting in a too large timeout value for the qdisc watchdog. Use "now" instead, which still contains the current time. Signed-off-by:

The timer resolution exported in /proc/net/psched is used by userspace to calculate HTB's burst values. Currently it is set to HZ, since we're now using hrtimers, use KTIME_MONOTONIC_RES, which makes HTB use smaller burst values. This patch also affects libnl, which incorrectly uses this value for the SFQ perturbation parameter, which is always in seconds, and some routing cache values, which are in USER_HZ, so both cases are broken anyway.

Now that all packet schedulers have been converted to hrtimers most users of PSCHED_JIFFIE2US and PSCHED_US2JIFFIE are gone. The remaining users use it to convert external time units to packet scheduler clock ticks, so use PSCHED_TICKS_PER_SEC instead. Signed-off-by:

Switch delay_timer to hrtimer. The class penalty parameter is changed to use psched ticks as units. Since iproute never supported using this and the only existing user (libnl) incorrectly assumes psched ticks as units anyway, this shouldn't break anything. Signed-off-by:

cbq_undelay_prio is supposed to return a time delta, but returns the current time for non-active priorities, causing cbq_undelay to mark the priority as active and schedule a timer for twice the current time. Signed-off-by:

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:

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 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:

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:

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:

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:
