TIPC name table updates are distributed asynchronously in a cluster, entailing a risk of certain race conditions. E.g., if two nodes simultaneously issue conflicting (overlapping) publications, this may not be detected until both publications have reached a third node, in which case one of the publications will be silently dropped on that node. Hence, we end up with an inconsistent name table. In most cases this conflict is just a temporary race, e.g., one node is issuing a publication under the assumption that a previous, conflicting, publication has already been withdrawn by the other node. However, because of the (rtt related) distributed update delay, this may not yet hold true on all nodes. The symptom of this failure is a syslog message: "tipc: Cannot publish {%u,%u,%u}, overlap error". In this commit we add a resiliency queue at the receiving end of the name table distributor. When insertion of an arriving publication fails, we retain it in this queue for a short amount of time, assuming that another update will arrive very soon and clear the conflict. If so happens, we insert the publication, otherwise we drop it. The (configurable) retention value defaults to 2000 ms. Knowing from experience that the situation described above is extremely rare, there is no risk that the queue will accumulate any large number of items.

We need to perform the same actions when processing deferred name table updates, so this functionality is moved to a separate function.

Because the Tx has the features of stopping queue and aggregation, We don't need many tx buffers. Change the tx number from 10 to 4 to reduce the usage of the memory. This could save 16K * 6 bytes memory. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

David Miller says: ==================== net: Make dev_hard_start_xmit() work fundamentally on lists After this patch set, dev_hard_start_xmit() will work fundemantally on any and all SKB lists. This opens the path for a clean implementation of pulling multiple packets out during qdisc_restart(), and then passing that blob in one shot to dev_hard_start_xmit(). There were two main architectural blockers to this: 1) The GSO handling, we kept the original GSO head SKB around simply because dev_hard_start_xmit() had no way to communicate to the caller how far into the segmented list it was able to go. Now it can, so the head GSO can be liberated immediately. All of the special GSO head SKB destructor et al. handling goes away too. 2) Validate of VLAN, CSUM, and segmentation characteristics was being performed inside of dev_hard_start_xmit(). If want to truly batch, we have to let the higher levels to this. In particular, this is now dequeue_skb()'s job. And with those two issues out of the way, it should now be trivial to build experiments on top of this patch set, all of the framework should be there now. You could do something as simple as: skb = q->dequeue(q); if (skb) skb = validate_xmit_skb(skb, qdisc_dev(q)); if (skb) { struct sk_buff *new, *head = skb; int limit = 5; do { new = q->dequeue(q); if (new) new = validate_xmit_skb(new, qdisc_dev(q)); if (new) { skb->next = new; skb = new; } } while (new && --limit); skb = head; } inside of the else branch of dequeue_skb().

dev_hard_start_xmit() does two things, it first validates and canonicalizes the SKB, then it actually sends it. Make a set of helper functions for doing the first part. Signed-off-by: David S. Miller <davem@davemloft.net>

There is a slight policy change happening here as well. The previous code would drop the entire rest of the GSO skb if any of them got, for example, a congestion notification. That makes no sense, anything NET_XMIT_MASK and below is something like congestion or policing. And in the congestion case it doesn't even mean the packet was actually dropped. Just continue until dev_xmit_complete() evaluates to false. Signed-off-by: David S. Miller <davem@davemloft.net>

Tom Herbert says: ==================== net: Checksum offload changes - Part VI I am working on overhauling RX checksum offload. Goals of this effort are: - Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY - Preserve CHECKSUM_COMPLETE through encapsulation layers - Don't do skb_checksum more than once per packet - Unify GRO and non-GRO csum verification as much as possible - Unify the checksum functions (checksum_init) - Simplify code What is in this sixth patch set: - Clarify the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Add csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model. - Allow GRO path to "consume" checksums provided in CHECKSUM_UNNECESSARY and to report new verfied checksums for use in normal path fallback. - Add proper support to SCTP to accept CHECKSUM_UNNECESSARY to validate header CRC. - Modify drivers to set skb->csum_level instead of setting skb->encapsulation to indicate validation of an encapsulated checksum on receive. v2: Allocate a new 16 bits for flags in skbuff. Please review carefully and test if possible, mucking with basic checksum functions is always a little precarious :-) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Allow GRO path to "consume" checksums provided in CHECKSUM_UNNECESSARY and to report new checksums verfied for use in fallback to normal path. Change GRO checksum path to track csum_level using a csum_cnt field in NAPI_GRO_CB. On GRO initialization, if ip_summed is CHECKSUM_UNNECESSARY set NAPI_GRO_CB(skb)->csum_cnt to skb->csum_level + 1. For each checksum verified, decrement NAPI_GRO_CB(skb)->csum_cnt while its greater than zero. If a checksum is verfied and NAPI_GRO_CB(skb)->csum_cnt == 0, we have verified a deeper checksum than originally indicated in skbuf so increment csum_level (or initialize to CHECKSUM_UNNECESSARY if ip_summed is CHECKSUM_NONE or CHECKSUM_COMPLETE).

This patch: - Clarifies the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Adds csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). This replaces the overloading of skb->encapsulation, that field is is now only used to indicate inner headers are valid. - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model.

Commit 6c9808ce ("tipc: remove port_lock") accidentally involves a potential bug: when tipc socket instance(tsk) is not got with given reference number in tipc_sk_get(), tsk is set to NULL. Subsequently we jump to exit label where to decrease socket reference counter pointed by tsk pointer in tipc_sk_put(). However, As now tsk is NULL, oops may happen because of touching a NULL pointer.

This patch adds support to run Power On Self Test (POST) for 83xx adapters. POST can be run in 3 different speed modes : i) Fast mode (takes about 690 ms) ii) Medium mode (takes about 2930 ms) iii) Slow mode (takes about 7500 ms) To run POST, firmware file with name "83xx_post_fw.bin" should be present under /lib/firmware directory. load_fw_file module parameter is used to specify POST operation and its speed mode. load_fw_file = 2 : Fast mode load_fw_file = 3 : Medium mode load_fw_file = 4 : Slow mode Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.
