This puts CONFIG_PROC_FS defines around the proc init/exit functions and also avoids compiling proc.c if procfs is not supported. Also make SCTP_DBG_OBJCNT depend on procfs. Signed-off-by:

Some of the metrics (RTT, RTTVAR and RTAX_RTO_MIN) are stored in kernel units (jiffies) and this leaks out through the netlink API to user space where the units for jiffies are unknown. This patches changes the kernel to convert to/from milliseconds. This changes the ABI, but milliseconds seemed like the most natural unit for these parameters. Values available via syscall in /proc/net/rt_cache and netlink will be in milliseconds. Signed-off-by:

Idea is from Patrick McHardy. Instead of managing the list of qdiscs on the device level, manage it in the root qdisc of a netdev_queue. This solves all kinds of visibility issues during qdisc destruction. The way to iterate over all qdiscs of a netdev_queue is to visit the netdev_queue->qdisc, and then traverse it's list. The only special case is to ignore builting qdiscs at the root when dumping or doing a qdisc_lookup(). That was not needed previously because builtin qdiscs were not added to the device's qdisc_list.

The u32_list is just an indirect way of maintaining a reference to a U32 node on a per-qdisc basis. Just add an explicit node pointer for u32 to struct Qdisc an do away with this global list. Signed-off-by: -

Add new sockopt to reserve some headroom in the mmaped ring frames in front of the packet payload. This can be used f.i. when the VLAN header needs to be (re)constructed to avoid moving the entire payload. Signed-off-by:

This change allows the first TX ring (CID 16) and the first TSS TX ring (CID 32) to be used concurrently. Before this change, we could get TSO errors when both TX rings were used concurrently. Signed-off-by:

With the recent changes to tx mutiqueue, e1000 was not calling netif_start_queue() before calling netif_wake_queue(). This causes an oops during loading of the driver. (Based on commit d55b53ff ("igb/ixgbe/e1000e: resolve tx multiqueue bug").) Signed-off-by:

The only structure declared within is the netns_mib, which will carry all our mibs within. I didn't put the mibs in the existing netns_xxx structures to make it possible to mark this one as properly aligned and get in a separate "read-mostly" cache-line. Signed-off-by:

Instead of 'pfifo_fast' we have just plain 'fifo_fast'. No priority queues, just a straight FIFO. This is necessary in order to legally have a seperate qdisc per queue in multi-TX-queue setups, and thus get full parallelization. Signed-off-by: -
David S. Miller authored
We have to have exclusive access to the given qdisc anyways, so doing even more locking is superfluous. Signed-off-by: -
David S. Miller authored
Move the destruction of the old queue into qdisc_graft(). When operating on a root qdisc (ie. "parent == NULL"), apply the operation to all queues. The caller has grabbed a single implicit reference for this graft, therefore when we apply the change to more than one queue we must grab additional qdisc references. Otherwise, we are operating on a class of a specific parent qdisc, and therefore no multiqueue handling is necessary. Signed-off-by: -
