2020-08-03net: stmmac: fix failed to suspend if phy based WOL is enabledJisheng Zhang
With the latest net-next tree, if test suspend/resume after enabling WOL, we get error as below: [ 487.086365] dpm_run_callback(): mdio_bus_suspend+0x0/0x30 returns -16 [ 487.086375] PM: Device stmmac-0:00 failed to suspend: error -16 -16 means -EBUSY, this is because I didn't enable wakeup of the correct device when implementing phy based WOL feature. To be honest, I caught the issue when implementing phy based WOL and then fix it locally, but forgot to amend the phy based wol patch. Today, I found the issue by testing net-next tree.

2020-08-03libnvdimm/security: ensure sysfs poll thread woke up and fetch updated attrJane Chu
commit 7d988097c546 ("acpi/nfit, libnvdimm/security: Add security DSM overwrite support") adds a sysfs_notify_dirent() to wake up userspace poll thread when the "overwrite" operation has completed. But the notification is issued before the internal dimm security state and flags have been updated, so the userspace poll thread wakes up and fetches the not-yet-updated attr and falls back to sleep, forever. But if user from another terminal issue "ndctl wait-overwrite nmemX" again, the command returns instantly.

2020-08-03libnvdimm/security: the 'security' attr never show 'overwrite' stateJane Chu
'security' attribute displays the security state of an nvdimm. During normal operation, the nvdimm state maybe one of 'disabled', 'unlocked' or 'locked'. When an admin issues # ndctl sanitize-dimm nmem0 --overwrite the attribute is expected to change to 'overwrite' until the overwrite operation completes. But tests on our systems show that 'overwrite' is never shown during the overwrite operation. i.e. # cat /sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0012:00/ndbus0/nmem0/security unlocked the attribute remain 'unlocked' through out the operation, consequently "ndctl wait-overwrite nmem0" command doesn't wait at all. The driver tracks the state in 'nvdimm->sec.flags': when the operation starts, it adds an overwrite bit to the flags; and when the operation completes, it removes the bit. Hence security_show() should check the 'overwrite' bit first, in order to indicate the actual state when multiple bits are set in the flags.

2020-08-04gpio: don't use same lockdep class for all devm_gpiochip_add_data usersAhmad Fatoum
Commit 959bc7b22bd2 ("gpio: Automatically add lockdep keys") documents in its commits message its intention to "create a unique class key for each driver". It does so by having gpiochip_add_data add in-place the definition of two static lockdep classes for LOCKDEP use. That way, every caller of the macro adds their gpiochip with unique lockdep classes. There are many indirect callers of gpiochip_add_data, however, via use of devm_gpiochip_add_data. devm_gpiochip_add_data has external linkage and all its users will share the same lockdep classes, which probably is not intended. Fix this by replicating the gpio_chip_add_data statics-in-macro for the devm_ version as well.

2020-08-03atm: idt77252: avoid accessing the data mapped to streaming DMAJia-Ju Bai
In queue_skb(), skb->data is mapped to streaming DMA on line 850: dma_map_single(..., skb->data, ...); Then skb->data is accessed on lines 862 and 863: tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) | (skb->data[2] << 8) | (skb->data[3] << 0); and on lines 893 and 894: tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) | (skb->data[2] << 8) | (skb->data[3] << 0); These accesses may cause data inconsistency between CPU cache and hardware. To fix this problem, the calculation result of skb->data is stored in a local variable before DMA mapping, and then the driver accesses this local variable instead of skb->data.

2020-08-03atm: eni: avoid accessing the data mapped to streaming DMAJia-Ju Bai
In do_tx(), skb->data is mapped to streaming DMA on line 1111: paddr = dma_map_single(...,skb->data,DMA_TO_DEVICE); Then skb->data is accessed on line 1153: (skb->data[3] & 0xf) This access may cause data inconsistency between CPU cache and hardware. To fix this problem, skb->data[3] is assigned to a local variable before DMA mapping, and then the driver accesses this local variable instead of skb->data[3].

This adds full 802.1q VLAN support to the qca8k, allowing the use of vlan_filtering and more complicated bridging setups than allowed by basic port VLAN support. Tested with a number of untagged ports with separate VLANs and then a trunk port with all the VLANs tagged on it. v3: - Pull QCA8K_PORT_VID_DEF changes into separate cleanup patch - Reverse Christmas tree notation for variable definitions - Use untagged instead of tagged for consistency v2: - Return sensible errnos on failure rather than -1 (rmk) - Style cleanups based on Florian's feedback - Silently allow VLAN 0 as device correctly treats this as no tag Signed-off-by: Jonathan McDowell <noodles@earth.li> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Acked-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: David S.

Rather than using a magic value of 1 when configuring the port VIDs add a QCA8K_PORT_VID_DEF define and use that instead. Also fix up the bitmask in the process; the top 4 bits are reserved so this wasn't a problem, but only masking 12 bits is the correct approach.

Wei Yongjun marks power management functions with __maybe_unused. Nick disables VLAN pruning in promiscuous mode and renames grst_delay to grst_timeout. Kiran modifies the check for linearization and corrects the vsi_id mask value. Vignesh replaces the use of flow profile locks to RSS profile locks for RSS rule removal. Destroys flow profile lock on clearing XLT table and clears extraction sequence entries. Jesse adds some statistics and removes an unreported one. Brett allows for 2 queue configuration for VFs. Surabhi adds a check for failed allocation of an extraction sequence table. Tony updates the PTYPE lookup table and makes other trivial fixes.

2020-08-03cxgb4: fix extracting IP addresses in TC-FLOWER rulesRahul Lakkireddy
commit c8729cac2a11 ("cxgb4: add ethtool n-tuple filter insertion") has removed checking control key for determining IP address types for TC-FLOWER rules, which causes all the rules being inserted to hardware to become IPv6 rule type always. So, add back the check to select the correct IP address type to extract and hence fix the correct rule type being inserted to hardware. Also, ethtool_rx_flow_key doesn't have any control key and instead directly sets the IPv4/IPv6 address keys. So, explicitly set the IP address type for ethtool n-tuple filters to reuse the same code.

2020-08-03of: unittest: Use bigger address cells to catch parser regressionsNicolas Saenz Julienne
Getting address and size cells for dma-ranges/ranges parsing is tricky and shouldn't rely on the node's count_cells() method. The function starts looking for cells on the parent node, as its supposed to work with device nodes, which doesn't work when input with bus nodes, as generally done when parsing ranges. Add test to catch regressions on that specific quirk as developers will be tempted to edit it out in favor of the default method.
