* [PATCH] cfq-iosched: many performance fixesJens Axboe2006-06-23
| | | | | | | | | | | | | | | | | | | | This is a collection of patches that greatly improve CFQ performance in some circumstances. - Change the idling logic to only kick in after a request is done and we are deciding what to do. Before the idling included the request service time, so it was hard to adjust. Now it's true think/idle time. - Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep it in control for sync and sequential (or close to) workloads. - Expire queues immediately and move on to other busy queues, if we are not going to idle after the current one finishes. - Don't rearm idle timer if there are no busy queues. Just leave the system idle. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] cfq-iosched: correctly set ioprio on both targetsJens Axboe2006-06-23
| | | | | | | | | | | | | | | | | Patch originally from Vasily Tarasov <vtaras@sw.ru> If you set io-priority of process 1 using sys_ioprio_set system call by another process 2 (like ionice do), then cfq_init_prio_data() function sets priority of process 2 (current) on queue of process 1 and clears the flag, that designates change of ioprio. So the process 1 will work like with priority of process 2. I propose not to call cfq_init_prio_data() on io-priority change, but only mark queue as queue with changed prority. Every time when new request comes cfq-scheduler checks for this flag and atomaticaly changes priority of queue to new value. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] Kill PF_SYNCWRITE flagJens Axboe2006-06-23
| | | | | | | | | | | | | | | A process flag to indicate whether we are doing sync io is incredibly ugly. It also causes performance problems when one does a lot of async io and then proceeds to sync it. Part of the io will go out as async, and the other part as sync. This causes a disconnect between the previously submitted io and the synced io. For io schedulers such as CFQ, this will cause us lost merges and suboptimal behaviour in scheduling. Remove PF_SYNCWRITE completely from the fsync/msync paths, and let the O_DIRECT path just directly indicate that the writes are sync by using WRITE_SYNC instead.

| | | | | | | | | | | | | | The queue lock can be taken from interrupts so it must always be taken with irq disabling primitives. Some primitives already verify this. blk_start_queue() is called under this lock, so interrupts must be disabled.

| * [NET]: Require CAP_NET_ADMIN to create tuntap devices.David Woodhouse2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | The tuntap driver allows an admin to create persistent devices and assign ownership of them to individual users. Unfortunately, relaxing the permissions on the /dev/net/tun device node so that they can actually use those devices will _also_ allow those users to create arbitrary new devices of their own. This patch corrects that, and adjusts the recommended permissions for the device node accordingly. Signed-off-By: David Woodhouse <dwmw2@infradead.org> Signed-off-by: David S.

| * [IPSEC]: Handle GSO packetsHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch segments GSO packets received by the IPsec stack. This can happen when a NIC driver injects GSO packets into the stack which are then forwarded to another host. The primary application of this is going to be Xen where its backend driver may inject GSO packets into dom0. Of course this also can be used by other virtualisation schemes such as VMWare or UML since the tap device could be modified to inject GSO packets received through splice.

| * [NET]: Add generic segmentation offloadHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the infrastructure for generic segmentation offload. The idea is to tap into the potential savings of TSO without hardware support by postponing the allocation of segmented skb's until just before the entry point into the NIC driver. The same structure can be used to support software IPv6 TSO, as well as UFO and segmentation offload for other relevant protocols, e.g., DCCP.

| * [NET]: Merge TSO/UFO fields in sk_buffHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NET]: Prevent transmission after dev_deactivateHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dev_deactivate function has bit-rotted since the introduction of lockless drivers. In particular, the spin_unlock_wait call at the end has no effect on the xmit routine of lockless drivers. With a little bit of work, we can make it much more useful by providing the guarantee that when it returns, no more calls to the xmit routine of the underlying driver will be made. The idea is simple. There are two entry points in to the xmit routine. The first comes from dev_queue_xmit. That one is easily stopped by using synchronize_rcu. This works because we set the qdisc to noop_qdisc before the synchronize_rcu call. That in turn causes all subsequent packets sent to dev_queue_xmit to be dropped. The synchronize_rcu call also ensures all outstanding calls leave their critical section. The other entry point is from qdisc_run. Since we now have a bit that indicates whether it's running, all we have to do is to wait until the bit is off. I've removed the loop to wait for __LINK_STATE_SCHED to clear. This is useless because netif_wake_queue can cause it to be set again. It is also harmless because we've disarmed qdisc_run. I've also removed the spin_unlock_wait on xmit_lock because its only purpose of making sure that all outstanding xmit_lock holders have exited is also given by dev_watchdog_down.

| * [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
