when the source sg contains more than 1 fragment and destination sg contains 1 fragment, the caam driver mishandle the buffers to be sent to caam.

2019-02-08crypto: ccp - fix the SEV probe in kexec boot pathSingh, Brijesh
A kexec reboot may leave the firmware in INIT or WORKING state. Currently, we issue PLATFORM_INIT command during the probe without checking the current state. The PLATFORM_INIT command fails if the FW is already in INIT state. Lets check the current state, if FW is not in UNINIT state then transition it to UNINIT before initializing or upgrading the FW.

2019-02-08crypto: ccree - fix resume race condition on initGilad Ben-Yossef
We were enabling autosuspend, which is using data set by the hash module, prior to the hash module being inited, casuing a crash on resume as part of the startup sequence if the race was lost. This was never a real problem because the PM infra was using low res timers so we were always winning the race, until commit 8234f6734c5d ("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-) Fix this by seperating the PM setup and enablement and doing the latter only at the end of the init sequence.

2019-02-07net: phy: let genphy_c45_read_link manage the devices to checkHeiner Kallweit
Let genphy_c45_read_link manage the devices to check, this removes overhead from callers. Add C22EXT to the list of excluded devices because it doesn't implement the status register. According to the 802.3 clause 45 spec registers 29.0 - 29.4 are reserved. At the moment we have very few clause 45 PHY drivers, so we are lacking experience whether other drivers will have to exclude further devices, or may need to check PHY XS. If we should figure out that list of devices to check needs to be configurable, I think best will be to add a device list member to struct phy_driver. v2: - adjusted commit message - exclude also device C22EXT from link checking Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

When we add a new GENEVE device with IPv6 remote, checking only for IS_ENABLED(CONFIG_IPV6) is not enough as we may disable IPv6 in the kernel command line (ipv6.disable=1), and calling rt6_lookup() would cause a NULL pointer dereference. v2: - don't mix declarations and code (reported by Stefano Brivio, Eric Dumazet) - there's no need to use in6_dev_get() as we only need to check that idev exists (reported by David Ahern).

2019-02-07net/mlx5e: Add tx timeout support for mlx5e tx reporterEran Ben Elisha
With this patch, ndo_tx_timeout callback will be redirected to the tx reporter in order to detect a tx timeout error and report it to the devlink health. (The watchdog detects tx timeouts, but the driver verify the issue still exists before launching any recover method). In addition, recover from tx timeout in case of lost interrupt was added to the tx reporter recover method. The tx timeout recover from lost interrupt is not a new feature in the driver, this patch re-organize the functionality and move it to the tx reporter recovery flow. tx timeout example: (with auto_recover set to false, if set to true, the manual recover and diagnose sections are irrelevant) $cat /sys/kernel/debug/tracing/trace ... devlink_health_report: bus_name=pci dev_name=0000:00:09.0 driver_name=mlx5_core reporter_name=tx: TX timeout on queue: 0, SQ: 0x8a, CQ: 0x35, SQ Cons: 0x2 SQ Prod: 0x2, usecs since last trans: 14912000 $devlink health show pci/0000:00:09.0: name tx state healthy #err 1 #recover 0 last_dump_ts N/A parameters: grace_period 500 auto_recover false $devlink health diagnose pci/0000:00:09.0 reporter tx -j -p { "SQs": [ { "sqn": 138, "HW state": 1, "stopped": true },{ "sqn": 142, "HW state": 1, "stopped": false } ] } $devlink health diagnose pci/0000:00:09.0 reporter tx SQs: sqn: 138 HW state: 1 stopped: true sqn: 142 HW state: 1 stopped: false $devlink health recover pci/0000:00:09 reporter tx $devlink health show pci/0000:00:09.0: name tx state healthy #err 1 #recover 1 last_dump_ts N/A parameters: grace_period 500 auto_recover false Signed-off-by: Eran Ben Elisha <eranbe@mellanox.com> Reviewed-by: Moshe Shemesh <moshe@mellanox.com> Acked-by: Saeed Mahameed <saeedm@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2019-02-07net/mlx5e: Add tx reporter supportEran Ben Elisha
Add mlx5e tx reporter to devlink health reporters. This reporter will be responsible for diagnosing, reporting and recovering of tx errors. This patch declares the TX reporter operations and creates it using the devlink health API. Currently, this reporter supports reporting and recovering from send error CQE only. In addition, it adds diagnose information for the open SQs. For a local SQ recover (due to driver error report), in case of SQ recover failure, the recover operation will be considered as a failure. For a full tx recover, an attempt to close and open the channels will be done. If this one passed successfully, it will be considered as a successful recover. The SQ recover from error CQE flow is not a new feature in the driver, this patch re-organize the functions and adapt them for the devlink health API. For this purpose, move code from en_main.c to a new file named reporter_tx.c.

In order to restart WCN3990 firmware, the driver needs to send qmi_wlan_disable message followed by the qmi_wlan_enable message to the WCN3990 firmware. Currently the qmi_wlan_disable message is not sent to the WCN3990 firmware when hw-restart crash is injected, which causes the firmware to crash when the driver sends qmi_wlan_enable message during ath10k_restart.

2019-02-07ath10k: Enable bundle tx compl for management frames in WCN3990Rakesh Pillai
WCN3990 sends tx completion of multiple management frames bundled together in a single event, if the host driver exposes the support to handle this bundled tx completion event. This reduces the number of WMI events which are sent to the host driver by the target. Set the BUNDLE_TX_COMPL flag in the host capability flags when host sends the wmi init command, to indicate the host capability to handle bundled tx completion for management frames.

HOST capability interface data structures are updated in HL3.1 fw version. Update the qmi host capability members for compatibility across different firmware versions. Since this change breaks backward compatibility with HL2.0 fw, HL2.0 fw upgrade to WLAN.HL.2.0-01617-QCAHLSWMTPLZ-1 or later version is required. Testing: Tested on QCS404 platform(WCN3990 HW).

2019-02-07ACPI: Set debug output flags independent of ACPICAErik Schmauss
There was a divergence between Linux and ACPICA on the definition of ACPI_DEBUG_DEFAULT. This divergence was solved by taking ACPICA's definition in 4c1379d7bb42. After resolving the divergence, it was clear that Linux users wanted to use their old set of debug flags. This change fixes the divergence by setting these debug flags during acpi_early_init() rather than during global variable initialization in acpixf.h (owned by ACPICA).
