This restores commits: c573972c 1a590434 da2e2c21 which initially accidently went into 'net', were reverted there, and then properly placed into 'net-next'. But the next net --> net-next merge accidently wiped them out again. Reported-by:

Callers of skb_seq_read() are currently forced to call skb_abort_seq_read() even when consuming all the data because the last call to skb_seq_read (the one that returns 0 to indicate the end) fails to unmap the last fragment page. With this patch callers will be allowed to traverse the SKB data by calling skb_prepare_seq_read() once and repeatedly calling skb_seq_read() as originally intended (and documented in the original commit 677e90ed), that is, only call skb_abort_seq_read() if the sequential read is actually aborted.

John W. Linville says: ==================== I would guess that this is the last big wireless pull request before the 3.11 merge window... Regarding the mac80211 bits, Johannes says: "I have a number of mesh fixes and improvements from Colleen, Jacob, Ashok and Thomas, powersave fixes in mac80211 from Alex, improved management-TX from Antonio, and a few various things, including locking fixes, from others and myself. Overall though, nothing really stands out." As for the iwlwifi bits, Johannes says: "Emmanuel contributed two AP mode fixes, removed an unused field, fixed a comment and added a warning for something that shouldn't happen in practice, and I removed the declaration of a function that doesn't even exist and cleaned up a small include." "This time I have a number of cleanups, a small fix from Emmanuel and two performance improvements that combined reduce our driver's CPU utilisation as much as 75% in high TX-throughput scenarios." "These two patches fix two issues with using rfkill randomly during traffic, which would then cause our driver to stop working and not be able to recover at all." Regarding the ath6kl bits, Kalle says: "Here are few simple patches for ath6kl. We have a suspend crash fix for USB from Shafi, use of mac_pton(), a compiler warning fix and a fix for module initialisation error path." Kalle also sends the biggest single item of note, the new ath10k driver for Qualcomm Atheros 802.11ac CQA98xx devices. Included is an NFC pull, of which Samuel says: "These are the pending NFC patches for the 3.11 merge window. It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2), along with a few more for the pn544 and pn533 drivers, the LLCP disconnection path and an LLCP memory leak. Highlights for this one are: - An initial secure element API. NFC chipsets can carry an embedded secure element or get access to the SIM one. In both cases they control the secure elements and this API provides a way to discover, enable and disable the available SEs. It also exports that to userspace in order for SE focused middleware to actually do something with them (e.g. payments). - NCI over SPI support. SPI is the most complex NCI specified transport layer and we now have support for it in the kernel. The next step will be to implement drivers for NCI chipsets using this transport like e.g. bcm2079x. - NFC p2p hardware simulation driver. We now have an nfcsim driver that is mostly a loopback device between 2 NFC interfaces. It also implements the rest of the NFC core API like polling and target detection. This driver, with neard running on top of it, allows us to completely test the LLCP, SNEP and Handover implementation without physical hardware. - A Firmware update netlink API. Most (All ?) HCI chipsets have a special firmware update mode where applications can push a new firmware that will be flashed. We now have a netlink API for providing that mode to e.g. nfctool." On top of all that, there are a variety of updates to brcmfmac, iwlegacy, rtlwifi, wil6210, and the TI wl12xx drivers. As usual, the bcma and ssb busses get a little love as well, as do a handful of others here and there. ==================== Signed-off-by: -

netif_alloc_netdev_queues() uses kcalloc() to allocate memory for the "struct netdev_queue *_tx" array. For large number of tx queues, kcalloc() might fail, so this patch does a fallback to vzalloc(). As vmalloc() adds overhead on a critical network path, add __GFP_REPEAT to kzalloc() flags to do this fallback only when really needed. Signed-off-by:

htb_sched structures are big, and source of false sharing on SMP. Every time a packet is queued or dequeue, many cache lines must be touched because structures are not lay out properly. By carefully splitting htb_sched in two parts, and define sub structures to increase data locality, we can improve performance dramatically on SMP. New htb_prio structure can also be used in htb_class to increase data locality. I got 26 % performance increase on a 24 threads machine, with 200 concurrent netperf in TCP_RR mode, using a HTB hierarchy of 4 classes. Signed-off-by:

In previous discussions, I tried to find some reasonable heuristics for delayed ACK, however this seems not possible, according to Eric: "ACKS might also be delayed because of bidirectional traffic, and is more controlled by the application response time. TCP stack can not easily estimate it." "ACK can be incredibly useful to recover from losses in a short time. The vast majority of TCP sessions are small lived, and we send one ACK per received segment anyway at beginning or retransmits to let the sender smoothly increase its cwnd, so an auto-tuning facility wont help them that much." and according to David: "ACKs are the only information we have to detect loss. And, for the same reasons that TCP VEGAS is fundamentally broken, we cannot measure the pipe or some other receiver-side-visible piece of information to determine when it's "safe" to stretch ACK. And even if it's "safe", we should not do it so that losses are accurately detected and we don't spuriously retransmit. The only way to know when the bandwidth increases is to "test" it, by sending more and more packets until drops happen. That's why all successful congestion control algorithms must operate on explicited tested pieces of information. Similarly, it's not really possible to universally know if it's safe to stretch ACK or not." It still makes sense to enable or disable quick ack mode like what TCP_QUICK_ACK does. Similar to TCP_QUICK_ACK option, but for people who can't modify the source code and still wants to control TCP delayed ACK behavior. As David suggested, this should belong to per-path scope, since different pathes may want different behaviors.

ETRAX_ETHERNET selects ETHERNET and MII, which depend on NETDEVICES. I don't think anything should select NETDEVICES, so make it a dependency. It also doesn't need to select or depend on ETHERNET, which has nothing to do with the Ethernet library functions. BPCTL selects MII, which depends on NETDEVICES. But everything in the drivers/staging/silicom directory is related to net devices, so make NET_VENDOR_SILICOM depend on NETDEVICES and remove the now-redundant dependencies on NET. Signed-off-by:

All drivers that select MII also need to select NET_CORE because MII depends on it. This is a bit ridiculous because NET_CORE is just a menu option that doesn't enable any code by itself. There is also no need for it to be a visible option, since its users all select it. Signed-off-by:
