This patch move RX queue allocation to alloc_netdev_mq and freeing of the queues to free_netdev (symmetric to TX queue allocation). Each kobject RX queue takes a reference to the queue's device so that the device can't be freed before all the kobjects have been released-- this obviates the need for reference counts specific to RX queues.

Now that VLAN packets are tagged in dev_hard_start_xmit() at the bottom of the stack we no longer need to tag them in the 8021Q module (Except in the !VLAN_FLAG_REORDER_HDR case). This allows the accel path and non accel paths to be consolidated. Here the vlan_tci in the skb is always set and we allow the stack to add the actual tag in dev_hard_start_xmit().

It is possible for the headroom to be smaller then the hard_header_len for a short period of time after toggling the vlan offload setting. This is not a hard error and skb_cow_head is called in __vlan_put_tag() to resolve this.

Toggling the vlan tx|rx hw offloads needs to set the hard_header_len as well otherwise we end up using LL_RESERVED_SPACE incorrectly. This results in pskb_expand_head() being used unnecessarily.

We currently use vlan_features to check for TSO support if there is a vlan tag. However, it's quite likely that the NIC is not able to do TSO when there is an arbitrary number of tags. Therefore if there is more than one tag (in-band or out-of-band), fall back to software emulation.

由 Jesse Gross 提交于
When checking if it is necessary to linearize a packet, we currently use vlan_features if the packet contains either an in-band or out- of-band vlan tag. However, in-band tags aren't special in any way for scatter/gather since they are part of the packet buffer and are simply more data to DMA. Therefore, only use vlan_features for out- of-band tags, which could potentially have some interaction with scatter/gather.

由 Gerrit Renker 提交于
This patch replaces an almost identical replication of code: large parts of dccp_parse_options() re-appeared as ccid2_ackvector() in ccid2.c. Apart from the duplication, this caused two more problems: 1. CCIDs should not need to be concerned with parsing header options; 2. one can not assume that Ack Vectors appear as a contiguous area within an skb, it is legal to insert other options and/or padding in between. The current code would throw an error and stop reading in such a case. Since Ack Vectors provide CCID-specific information, they are now processed by the CCID directly, separating this functionality from the main DCCP code.

This removes * functions for which updates have been provided in the preceding patches and * the @av_vec_len field - it is no longer necessary since the buffer length is now always computed dynamically. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>
-
由 Gerrit Renker 提交于
The problem with Ack Vectors is that i) their length is variable and can in principle grow quite large, ii) it is hard to predict exactly how large they will be. Due to the second point it seems not a good idea to reduce the MPS; in particular when on average there is enough room for the Ack Vector and an increase in length is momentarily due to some burst loss, after which the Ack Vector returns to its normal/average length. The solution taken by this patch is to subtract a minimum-expected Ack Vector length from the MPS, and to defer any larger Ack Vectors onto a separate Sync - but only if indeed there is no space left on the skb. This patch provides the infrastructure to schedule Sync-packets for transporting (urgent) out-of-band data. Its signalling is quicker than scheduling an Ack, since it does not need to wait for new application data. Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>

由 Gerrit Renker 提交于
This aggregates Ack Vector processing (handling input and clearing old state) into one function, for the following reasons and benefits: * all Ack Vector-specific processing is now in one place; * duplicated code is removed; * ensuring sanity: from an Ack Vector point of view, it is better to clear the old state first before entering new state; * Ack Event handling happens mostly within the CCIDs, not the main DCCP module.

This patch updates the code which registers new packets as received, using the new circular buffer interface. It contributes a new algorithm which * supports both tail/head pointers and buffer wrap-around and * deals with overflow (head/tail move in lock-step). Signed-off-by: NGerrit Renker <gerrit@erg.abdn.ac.uk>
-
由 Gerrit Renker 提交于
This provides a routine to consistently update the buffer state when the peer acknowledges receipt of Ack Vectors; updating state in the list of Ack Vectors as well as in the circular buffer. While based on RFC 4340, several additional (and necessary) precautions were added to protect the consistency of the buffer state. These additions are essential, since analysis and experience showed that the basic algorithm was insufficient for this task (which lead to problems that were hard to debug). The algorithm now * deals with HC-sender acknowledging to HC-receiver and vice versa, * keeps track of the last unacknowledged but received seqno in tail_ackno, * has special cases to reset the overflow condition when appropriate, * is protected against receiving older information (would mess up buffer state).
