2020-07-17Merge branch 'bcmgenet-WAKE_FILTER'David S. Miller
Doug Berger says: ==================== net: bcmgenet: fix WAKE_FILTER resume from deep sleep The WAKE_FILTER logic can only wake the system from the standby power state. However, some systems that include the GENET IP support deeper power saving states and the driver should suspend and resume correctly from those states as well. This commit set squashes a few issues uncovered while testing suspend and resume from these deep sleep states. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-17net: bcmgenet: restore HFB filters on resumeDoug Berger
The Hardware Filter Block RAM may not be preserved when the GENET block is reset during a deep sleep, so it is not sufficient to only backup and restore the enables. This commit clears out the HFB block and reprograms the rxnfc rules when the system resumes from a suspended state. To support this the bcmgenet_hfb_create_rxnfc_filter() function is modified to access the register space directly so that it can't fail due to memory allocation issues.

2020-07-17net: bcmgenet: test RBUF_ACPI_EN when resumingDoug Berger
When the GENET driver resumes from deep sleep the UMAC_CMD register may not be accessible and therefore should not be accessed from bcmgenet_wol_power_up_cfg() if the GENET has been reset. This commit adds a check of the RBUF_ACPI_EN flag when Wake on Filter is enabled. A clear flag indicates that the GENET hardware must have been reset so the remainder of the hardware programming is bypassed.

2020-07-12bnxt_en: Fix completion ring sizing with TPA enabled.Michael Chan
The current completion ring sizing formula is wrong with TPA enabled. The formula assumes that the number of TPA completions are bound by the RX ring size, but that's not true. TPA_START completions are immediately recycled so they are not bound by the RX ring size. We must add bp->max_tpa to the worst case maximum RX and TPA completions. The completion ring can overflow because of this mistake. This will cause hardware to disable the completion ring when this happens, leading to RX and TX traffic to stall on that ring. This issue is generally exposed only when the RX ring size is set very small. Fix the formula by adding bp->max_tpa to the number of RX completions if TPA is enabled.

2020-07-10mips: Remove compiler check in unroll macroNathan Chancellor
CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build (see our Travis link below). Clang 8 was chosen as a minimum version for this check because there were some improvements around __builtin_constant_p in that release. In reality, MIPS was not even buildable until clang 9 so that check was not technically necessary. Just remove all compiler checks and just assume that we have a working compiler.

Ido Schimmel says: ==================== mlxsw: Various fixes Fix two issues found by syzkaller. Patch #1 removes inappropriate usage of WARN_ON() following memory allocation failure. Constantly triggered when syzkaller injects faults. Patch #2 fixes a use-after-free that can be triggered by 'devlink dev info' following a failed devlink reload. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-10mlxsw: pci: Fix use-after-free in case of failed devlink reloadIdo Schimmel
In case devlink reload failed, it is possible to trigger a use-after-free when querying the kernel for device info via 'devlink dev info' [1]. This happens because as part of the reload error path the PCI command interface is de-initialized and its mailboxes are freed. When the devlink '->info_get()' callback is invoked the device is queried via the command interface and the freed mailboxes are accessed. Fix this by initializing the command interface once during probe and not during every reload. This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c') and also allows user space to query the running firmware version (for example) from the device after a failed reload.

Nicolas Ferre says: ==================== net: macb: Wake-on-Lan magic packet fixes and GEM handling Here is a split series to fix WoL magic-packet on the current macb driver. Only fixes in this one based on current net/master. Changes in v5: - Addressed the error code returned by phylink_ethtool_set_wol() as suggested by Russell. If PHY handles WoL, MAC doesn't stay in the way. - Removed Florian's tag on 3/5 because of the above changes. - Correct the "Fixes" tag on 1/5. Changes in v4: - Pure bug fix series for 'net'. GEM addition and MACB update removed: will be sent later. Changes in v3: - Revert some of the v2 changes done in macb_resume(). Now the resume function supports in-depth re-configuration of the controller in order to deal with deeper sleep states. Basically as it was before changes introduced by this series - Tested for non-regression with our deeper Power Management mode which cuts power to the controller completely Changes in v2: - Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()") needed for keeping phy state consistent - Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent putting the macb in runtime pm suspend mode when WoL is used - Collect review tags on 3 first patches from Florian: Thanks! - Review of macb_resume() function - Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers ==================== Signed-off-by: David S.

Keep previous function goals and integrate phylink actions to them. phylink_ethtool_get_wol() is not enough to figure out if Ethernet driver supports Wake-on-Lan. Initialization of "supported" and "wolopts" members is done in phylink function, no need to keep them in calling function. phylink_ethtool_set_wol() return value is considered and determines if the MAC has to handle WoL or not. The case where the PHY doesn't implement WoL leads to the MAC configuring it to provide this feature.

2020-07-10net: macb: mark device wake capable when "magic-packet" property presentNicolas Ferre
Change the way the "magic-packet" DT property is handled in the macb_probe() function, matching DT binding documentation. Now we mark the device as "wakeup capable" instead of calling the device_init_wakeup() function that would enable the wakeup source. For Ethernet WoL, enabling the wakeup_source is done by using ethtool and associated macb_set_wol() function that already calls device_set_wakeup_enable() for this purpose. That would reduce power consumption by cutting more clocks if "magic-packet" property is set but WoL is not configured by ethtool.
