I've seen timeout errors from HCI commands where it looks like schedule_timeout() has returned immediately; additional logging for the error case gives: req_status=1 req_result=0 remaining=10000 jiffies so the device is still in state HCI_REQ_PEND and the value returned by schedule_timeout() is the same as the original timeout (HCI_INIT_TIMEOUT on a system with HZ=1000). Use wait_event_interruptible_timeout() instead of open-coding similar behaviour which is subject to the spurious failure described above.

There are some controllers sending out advertising data with illegal length value which is longer than HCI_MAX_AD_LENGTH, causing the buffer last_adv_data overflows. To avoid these controllers from overflowing the buffer, we do not process the advertisement data if its length is incorrect.

btbcm_setup_patchram() starts with initializing the controller (and getting the firmware filename) and then after loading the firmware, does a re-init.

btbcm_finalize() does a re-init of the controller, which is almost the same as the initial init. Modify btbcm_initialize() so that it can be used for this re-init and modify btbcm_finalize() to use it. As an added bonus this also makes the dev_info from btbcm_finalize() use the proper hw_name instead of always printing "BCM".

Hans de Goede authored
btbcm_setup_patchram() was using the upper nibble of the revision code to determine if we are dealing with an uart or USB connected bcm-bt device, but just as btbcm_initialize() has started accepting 1 and 2 as uart connected devices, I've now encountered an USB connected device (0a5c:216c) which has 0 in the upper nibble. So it seems that the upper nibble is not really a reliable indicator of the bus type. Instead check hdev->bus which does give us a reliable indication. This fixes the patchram code trying to load the patchram by the fallback BCM.hcd filename, now it correctly requests BCM43142A0-0a5c-216c.hcd.

Interrupts specified through an "Interrupt" ACPI resource (versus through a "GpioInt" resource) are now always assumed to be active low. When this change was originally made the Thinkpad 8 quirk was kept around because it was uncertain if the Thinkpad 8 uses an "Interrupt" or a "GpioInt" resource. Bug https://bugzilla.kernel.org/show_bug.cgi?id=196701 has a DSDT for the Thinkpad 8 attached and it uses an "Interrupt" resource, so the quirk is not necessary and the quirk, as well as the irq-active-low quirk handling code can be removed.

The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430 wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does contain a valid ActiveLow GpioInt entry, but the GPIO it points to never goes low, so either the IRQ pin is not connected, or the ACPI resource- table points to the wrong GPIO. Eitherway things will not work if we try to use the specified IRQ, this commits adds a DMI based broken-irq blacklist and disables use of the IRQ and thus also runtime-pm for devices on this list. This blacklist starts with the the Meegopad T08, fixing bluetooth not working on this hdmi-stick. Since this is not a battery powered device the loss of runtime-pm is not really an issue.

This patch makes use of build_skb() throughout in driver's receieve data path [HW gro flow and non HW gro flow]. With this, driver can build skb directly from the page segments which are already mapped to the hardware instead of allocating new SKB via netdev_alloc_skb() and memcpy the data which is quite costly. This really improves performance (keeping same or slight gain in rx throughput) in terms of CPU utilization which is significantly reduced [almost half] in non HW gro flow where for every incoming MTU sized packet driver had to allocate skb, memcpy headers etc. Additionally in that flow, it also gets rid of bunch of additional overheads [eth_get_headlen() etc.] to split headers and data in the skb.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-05-17 This series contains updates to ixgbe, ixgbevf and ice drivers. Cathy Zhou resolves sparse warnings by using the force attribute. Mauro S M Rodrigues fixes a bug where IRQs were not freed if a PCI error recovery system opts to remove the device which causes ixgbe_io_error_detected() to return PCI_ERS_RESULT_DISCONNECT before calling ixgbe_close_suspend() which results in IRQs not freed and crashing when the remove handler calls pci_disable_device(). Resolved this by calling ixgbe_close_suspend() before evaluating the PCI channel state. Pavel Tatashin releases the rtnl_lock during the call to ixgbe_close_suspend() to allow scaling if device_shutdown() is multi-threaded. Emil modifies ixgbe to not validate the MAC address during a reset, unless the MAC was set on the host so that the VF will get a new MAC address every time it reloads. Also updates ixgbevf to set hw->mac.perm_addr in order to retain the custom MAC on a reset. Anirudh updates the ice NVM read/erase/update AQ commands to align with the latest specification. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

We recently refactored this code and introduced a static checker warning. Smatch complains that if cmd->index is zero then we would underflow the arrays. That's obviously true. The question is whether we prevent cmd->index from being zero at a different level. I've looked at the code and I don't immediately see a check for that.

Antoine Tenart says: ==================== net: mvpp2: phylink conversion This series convert the Marvell PPv2 driver to phylink (models the MAC to PHY link). One important point is the PPv2 driver supports two probe modes: device tree and ACPI. This series only brings phylink support for the device tree mode, as the ACPI one will need further work. Still, the driver should be working as before when using ACPI. This split should be temporary, and was discussed with Marcin (in Cc.) who added ACPI support to the driver. Also as the SFP cages on both DB boards can be considered as non-wired. We thus chose not to describe those SFP cages and we use fixed-link. The rest of the series uses phylink to add support for 1000BaseX and 2500BaseX modes in the PPv2 driver. To do this, two patches are needed in the common PHY framework (patches 3 and 4). The last 4 patches modify the device tree to use the new PPv2 functionalities. The series has been tested for the device tree mode on the 7040-db, 8040-db and 8040-mcbin boards, to ensure all the interface where working as expected. @Dave: patches 7 to 10 should go through the mvebu tree (Gregory in Cc.) to avoid any conflict with the other mvebu dt patches taken during this cycle. The series is based on today's net-next. Since v2: - Removed the SFP description from the DB boards, as their SFP cages are wired properly. We now use fixed-link. - Because of this rework, split the series in two, so that the SFP part is reviewed separately. - Small fixes in the phylink patch. - Rebased on the latest net-next branch. Since v1: - Chose a different approach to the SFP changes, as the previous ones weren't valid and reworked both BD boards device trees. - Misc fixes. - Added Kishon's acked-by on one patch. - Rebaed on latest net-next branch. ==================== Signed-off-by: David S.

Convert the PPv2 driver to implement phylink helpers, and use phylink in DT mode. The other mode supported is ACPI, which will need further work in order to be entirely compatible with phylink. The MAC and GoP configuration functions were completely moved to fit into the phylink helpers. When a PHY is always present between the MAC and the physical port, phylink only is used, but when this is not the case (the MAC directly is connected to the physical port) the link IRQ is used to detect changes in the link state and call phylink_mac_change. The ACPI mode do not uses phylink as of now, and the changes shouldn't impact its use. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
