This patch is based on an earlier one submitted by Jon Maxwell with the following commit message: "We recently encountered a bug where a few customers using ibmveth on the same LPAR hit an issue where a TCP session hung when large receive was enabled. Closer analysis revealed that the session was stuck because the one side was advertising a zero window repeatedly. We narrowed this down to the fact the ibmveth driver did not set gso_size which is translated by TCP into the MSS later up the stack. The MSS is used to calculate the TCP window size and as that was abnormally large, it was calculating a zero window, even although the sockets receive buffer was completely empty." We rely on the Virtual I/O Server partition in a pseries environment to provide the MSS through the TCP header checksum field. The stipulation is that users should not disable checksum offloading if rx packet aggregation is enabled through VIOS. Some firmware offerings provide the MSS in the RX buffer. This is signalled by a bit in the RX queue descriptor. Reviewed-by:

In flood situations, keeping sk_rmem_alloc at a high value prevents producers from touching the socket. It makes sense to lower sk_rmem_alloc only at the end of udp_rmem_release() after the thread draining receive queue in udp_recvmsg() finished the writes to sk_forward_alloc. Signed-off-by:

If udp_recvmsg() constantly releases sk_rmem_alloc for every read packet, it gives opportunity for producers to immediately grab spinlocks and desperatly try adding another packet, causing false sharing. We can add a simple heuristic to give the signal by batches of ~25 % of the queue capacity. This patch considerably increases performance under flood by about 50 %, since the thread draining the queue is no longer slowed by false sharing. Signed-off-by:

In UDP RX handler, we currently clear skb->dev before skb is added to receive queue, because device pointer is no longer available once we exit from RCU section. Since this first cache line is always hot, lets reuse this space to store skb->truesize and thus avoid a cache line miss at udp_recvmsg()/udp_skb_destructor time while receive queue spinlock is held.

Idea of busylocks is to let producers grab an extra spinlock to relieve pressure on the receive_queue spinlock shared by consumer. This behavior is requested only once socket receive queue is above half occupancy. Under flood, this means that only one producer can be in line trying to acquire the receive_queue spinlock. These busylock can be allocated on a per cpu manner, instead of a per socket one (that would consume a cache line per socket) This patch considerably improves UDP behavior under stress, depending on number of NIC RX queues and/or RPS spread.

The QDF2432 and the QDF2400 have slightly different internal PHYs, so there are some programming differences. Some of the registers in the QDF2400 have moved, and some registers require different values during initialization. Because of the differences, and because HIDs are a scare resource, the ACPI tables specify the hardware version in an _HRV property. Version 1 is the QDF2432, and version 2 is the QDF2400. Any future SOC that has the same internal PHY but different programming requirements will be assigned the next available version number. Signed-off-by:

The internal PHY of the EMAC differs on each SOC, and the list will only continue to grow. By separating the code into individual files, we can add support for more SOCs more cleanly. Note: The internal PHY is also sometimes called the SGMII device. We also stop referring to the various PHY variations by version number, so no more "v2", "v3", etc. Instead, the devices are named after the SOC they are, which is in sync with the device tree property names. Future patches will probably rearrange more code among the files. Signed-off-by:

Pull libnvdimm fixes from Dan Williams: "Several fixes to the DSM (ACPI device specific method) marshaling implementation. I consider these urgent enough to send for 4.9 consideration since they fix the kernel's handling of ARS (Address Range Scrub) commands. Especially for platforms without machine-check-recovery capabilities, successful execution of ARS commands enables the platform to potentially break out of an infinite reboot problem if a media error is present in the boot path. There is also a one line fix for a device-dax read-only mapping regression. Commits 9a901f54 ("acpi, nfit: fix extended status translations for ACPI DSMs") and 325896ff ("device-dax: fix private mapping restriction, permit read-only") are true regression fixes for changes introduced this cycle. Commit efda1b5d ("acpi, nfit, libnvdimm: fix / harden ars_status output length handling") fixes the kernel's handling of zero-length results, this never would have worked in the past, but we only just recently discovered a BIOS implementation that emits this arguably spec non-compliant result. The remaining two commits are additional fall out from thinking through the implications of a zero / truncated length result of the ARS Status command. In order to mitigate the risk that these changes introduce yet more regressions they are backstopped by a new unit test in commit a7de92da ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that mocks up inputs to acpi_nfit_ctl()" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix private mapping restriction, permit read-only tools/testing/nvdimm: unit test acpi_nfit_ctl() acpi, nfit: fix bus vs dimm confusion in xlat_status acpi, nfit: validate ars_status output buffer size acpi, nfit, libnvdimm: fix / harden ars_status output length handling acpi, nfit: fix extended status translations for ACPI DSMs

When mac80211 abandons an association attempt, it may free all the data structures, but inform cfg80211 and userspace about it only by sending the deauth frame it received, in which case cfg80211 has no link to the BSS struct that was used and will not cfg80211_unhold_bss() it. Fix this by providing a way to inform cfg80211 of this with the BSS entry passed, so that it can clean up properly, and use this ability in the appropriate places in mac80211. This isn't ideal: some code is more or less duplicated and tracing is missing. However, it's a fairly small change and it's thus easier to backport - cleanups can come later.

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned and the random MAC address to be used when privacy is enabled. When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26ab ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d3 ("cfg80211: Allow a scan request for a specific BSSID").

The array for initializing the cle is set up on the stack with almost entirely constant data and then passed to a function that converts it into HW specific bit patterns.
