2015-10-05asix: Continue processing URB if no RX netdev bufferDean Jenkins1-12/+19
Avoid a loss of synchronisation of the Ethernet Data header 32-bit word due to a failure to get a netdev socket buffer. The ASIX RX handling algorithm returned 0 upon a failure to get an allocation of a netdev socket buffer. This causes the URB processing to stop which potentially causes a loss of synchronisation with the Ethernet Data header 32-bit word. Therefore, subsequent processing of URBs may be rejected due to a loss of synchronisation. This may cause additional good Ethernet frames to be discarded along with outputting of synchronisation error messages. Implement a solution which checks whether a netdev socket buffer has been allocated before trying to copy the Ethernet frame into the netdev socket buffer. But continue to process the URB so that synchronisation is maintained. Therefore, only a single Ethernet frame is discarded when no netdev socket buffer is available.

2015-10-05asix: On RX avoid creating bad Ethernet framesDean Jenkins1-0/+28
When RX Ethernet frames span multiple URB socket buffers, the data stream may suffer a discontinuity which will cause the current Ethernet frame in the netdev socket buffer to be incomplete. This frame needs to be discarded instead of appending unrelated data from the current URB socket buffer to the Ethernet frame in the netdev socket buffer. This avoids creating a corrupted Ethernet frame in the netdev socket buffer. A discontinuity can occur when the previous URB socket buffer held an incomplete Ethernet frame due to truncation or a URB socket buffer containing the end of the Ethernet frame was missing. Therefore, add a sanity test for when an Ethernet frame spans multiple URB socket buffers to check that the remaining bytes of the currently received Ethernet frame point to a good Data header 32-bit word of the next Ethernet frame. Upon error, reset the remaining bytes variable to zero and discard the current netdev socket buffer. Assume that the Data header is located at the start of the current socket buffer and attempt to process the next Ethernet frame from there. This avoids unnecessarily discarding a good URB socket buffer that contains a new Ethernet frame.

2015-10-05asix: Simplify asix_rx_fixup_internal() netdev allocDean Jenkins1-9/+7
The code is checking that the Ethernet frame will fit into a netdev allocated socket buffer within the constraints of MTU size, Ethernet header length plus VLAN header length. The original code was checking rx->remaining each loop of the while loop that processes multiple Ethernet frames per URB and/or Ethernet frames that span across URBs. rx->remaining decreases per while loop so there is no point in potentially checking multiple times that the Ethernet frame (remaining part) will fit into the netdev socket buffer. The modification checks that the size of the Ethernet frame will fit the netdev socket buffer before allocating the netdev socket buffer. This avoids grabbing memory and then deciding that the Ethernet frame is too big and then freeing the memory.

2015-10-05asix: Tidy-up 32-bit header word synchronisationDean Jenkins1-15/+13
Tidy-up the Data header 32-bit word synchronisation logic in asix_rx_fixup_internal() by removing redundant logic tests. The code is looking at the following cases of the Data header 32-bit word that is present before each Ethernet frame: a) all 32 bits of the Data header word are in the URB socket buffer b) first 16 bits of the Data header word are at the end of the URB socket buffer c) last 16 bits of the Data header word are at the start of the URB socket buffer eg. split_head = true Note that the lifetime of rx->split_head exists outside of the function call and is accessed per processing of each URB. Therefore, split_head being true acts on the next URB to be processed. To check for b) the offset will be 16 bits (2 bytes) from the end of the buffer then indicate split_head is true. To check for c) split_head must be true because the first 16 bits have been found. To check for a) else c) Note that the || logic of the old code included the state (skb->len - offset == sizeof(u16) && rx->split_head) which is not possible because the split_head cannot be true whilst checking for b). This is because the split_head indicates that the first 16 bits have been found and that is not possible whilst checking for the first 16 bits. Therefore simplify the logic.

2015-10-05asix: Rename remaining and size for clarityDean Jenkins2-21/+22
The Data header synchronisation is easier to understand if the variables "remaining" and "size" are renamed. Therefore, the lifetime of the "remaining" variable exists outside of asix_rx_fixup_internal() and is used to indicate any remaining pending bytes of the Ethernet frame that need to be obtained from the next socket buffer. This allows an Ethernet frame to span across multiple socket buffers. "size" is now local to asix_rx_fixup_internal() and contains the size read from the Data header 32-bit word. Add "copy_length" to hold the number of the Ethernet frame bytes (maybe a part of a full frame) that are to be copied out of the socket buffer.

2015-10-05enic: do hang reset only in case of tx timeoutGovindarajulu Varadarajan4-3/+40
The current code invokes hang reset in case of error interrupt. We should hang reset only in case of tx timeout. This because of the way hang reset is implemented in firmware. Hang reset takes more firmware resources than soft reset. Adaptor does not generate error interrupt in case of tx timeout. Hang reset only in case of tx timeout, in .ndo_tx_timeout.

2015-10-05mwifiex: avoid gettimeofday in ba_threshold settingArnd Bergmann1-11/+4
mwifiex_get_random_ba_threshold() uses a complex homegrown implementation to generate a pseudo-random number from the current time as returned from do_gettimeofday(). This currently requires two 32-bit divisions plus a couple of other computations that are eventually discarded as only eight bits of the microsecond portion are used at all. We could replace this with a call to get_random_bytes(), but that might drain the entropy pool too fast if this is called for each packet. Instead, this patch converts it to use ktime_get_ns(), which is a bit faster than do_gettimeofday(), and then uses a similar algorithm as before, but in a way that takes both the nanosecond and second portion into account for slightly-more-but-still-not-very-random pseudorandom number.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-09-30 This series contains updates to i40e and i40evf only. Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e and i40evf. Shannon provides several updates and fixes, first fixes up a type clash in i40e_aq_rc_to_posix(), where the error codes are signed values, so we need to treat them as such. Then fixes up a padding issue where an extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly acknowledge the padding. Updated i40e to keep debugfs register read and writes from accessing outside of the io-remapped space. Added support and device id for another 20 GbE device. Jesse fixes the transmit hand workaround code for ARM that was causing Tx hangs to still occur occasionally when there really was no hang. Then fixed the receive dropped counter to show up in netstat interface. Refactor the interrupt enable function since it was always making the caller add the base_vector from the VSI struct which is already passed to the function. Fix kbuild warnings found in 0day build infrastructure by adding a harmless cast to a dev_info(), also fix 32 bit build warnings found by sparse. Greg fixed a configuration error that results if a port VLAN is set for a VF before the VF driver is loaded, so that when the VF driver is loaded the port VLAN is ignored. Mitch fixes the use of QOS field consistently in i40e_ndo_set_vf_port_vlan(). Modified the init timing of the driver to increase stability on load/unload and SR-IOV enable/disable cycles. Anjali updates i40e to not collect VEB stats if they are disabled in the hardware for performance reasons. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Pull IOVA fixes from David Woodhouse: "The main fix here is the first one, fixing the over-allocation of size-aligned requests. The other patches simply make the existing IOVA code available to users other than the Intel VT-d driver, with no functional change. I concede the latter really *should* have been submitted during the merge window, but since it's basically risk-free and people are waiting to build on top of it and it's my fault I didn't get it in, I (and they) would be grateful if you'd take it" * git://git.infradead.org/intel-iommu: iommu: Make the iova library a module iommu: iova: Export symbols iommu: iova: Move iova cache management to the iova library iommu/iova: Avoid over-allocating when size-aligned

Pull power management and ACPI fixes from Rafael Wysocki: "These are fixes mostly, for a few changes made in this cycle (the intel_idle driver, the OPP library, the ACPI EC driver, turbostat) and for some issues that have just been discovered (ACPI PCI IRQ management, PCI power management documentation, turbostat), with a couple of cleanups on top of them. Specifics: - intel_idle driver fixup for the recently added Skylake chips support (Len Brown). - Operating Performance Points (OPP) library fix related to the recently added support for new DT bindings and a fix for a typo in a comment (Viresh Kumar, Stephen Boyd). - ACPI EC driver fix for a recently introduced memory leak in an error code path (Lv Zheng). - ACPI PCI IRQ management fix for the issue where an ISA IRQ is shared with a PCI device which requires it to be configured in a different way and may cause an interrupt storm to happen as a result with an extra ACPI SCI IRQ handling simplification on top of it (Jiang Liu). - Update of the PCI power management documentation that became outdated and started to actively confuse the readers to make it actually reflect the code (Rafael J Wysocki). - turbostat fixes including an IVB Xeon regression fix (related to the --debug command line option), Skylake adjustment for the TSC running at a frequency that doesn't match the base one exactly, and a Knights Landing quirk to account for the fact that it only updates APERF and MPERF every 1024 clock cycles plus bumping up the turbostat version number (Len Brown, Hubert Chrzaniuk)" * tag 'pm+acpi-4.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: tools/power turbosat: update version number tools/power turbostat: SKL: Adjust for TSC difference from base frequency tools/power turbostat: KNL workaround for %Busy and Avg_MHz tools/power turbostat: IVB Xeon: fix --debug regression ACPI / PCI: Remove duplicated penalty on SCI IRQ ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQ ACPI / EC: Fix a memory leak issue in acpi_ec_query() PM / OPP: Fix typo modifcation -> modification PCI / PM: Update runtime PM documentation for PCI devices PM / OPP: of_property_count_u32_elems() can return errors intel_idle: Skylake Client Support - updated
