2020-03-18tty: fix compat TIOCGSERIAL checking wrong function ptrEric Biggers
Commit 77654350306a ("take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl()") changed the compat version of TIOCGSERIAL to start checking for the presence of the ->set_serial function pointer rather than ->get_serial. This appears to be a copy-and-paste error, since ->get_serial is the function pointer that is called as well as the pointer that is checked by the non-compat version of TIOCGSERIAL. Fix this by checking the correct function pointer.

2020-03-18ath11k: Perform per-msdu rx processingSriram R
As Hash based reo destination selection is configured, the decapped packets reach different reo destintion rings based on the destintaion ring selected for the computed hash (based on the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and as configured by driver. Hence the current implementation of amsdu list based processing after all the subframes of amsdu are received (since all msdu's for a pdev are received in same reo dest ring), is not applicable here and hence is replaced with per msdu based handling as these subframes can be received in different reo dest rings. Also, as some of the rx descriptor fields might be valid only for the first msdu (for ex. received 80211 header, encryption type, etc), it might not be useful now as we cannot sync between different subframes received in different rings. Hence do not rely on those fields and replace them with fieds valid only on per msdu descriptors. Also cache other details such as encryption type for a peer so that it can be reused when a packet is received from it.

2020-03-18ath11k: Adding proper validation before accessing tx_statsPravas Kumar Panda
Before dumping tx_stats proper validation was not been taken care of. Due to which we were encountering null pointer dereference(kernel panic). This scenario will arise when a station is getting disconnected and we are changing the STA state by ath11k_mac_op_sta_state and assigning tx_stats as NULL and after this the mac80211 will destroy the debugfs entry from where we are trying to read the stats. If anyone tries to dump tx_stats for that STA in between setting tx_stats to NULL and debugfs file removal without checking the NULL value it will run into a NULL pointer exception. Proceeding with the analysis of "ARM Kernel Panic". The APSS crash happened due to OOPS on CPU 3. Crash Signature : Unable to handle kernel NULL pointer dereference at virtual address 00000360 During the crash, PC points to "ath11k_debug_htt_stats_init+0x16ac/0x1acc [ath11k]" LR points to "ath11k_debug_htt_stats_init+0x1688/0x1acc [ath11k]".

last_keep_alive_jiffies is updated in probe and when a keep-alive event is received. In case the driver times-out on a keep-alive event, it has high chances of continuously timing-out on keep-alive events. This is because when the driver recovers from the keep-alive-timeout reset the value of last_keep_alive_jiffies is very old, and if a keep-alive event is not received before the next timer expires, the value of last_keep_alive_jiffies will cause another keep-alive-timeout reset and so forth in a loop.

2020-03-17net: ena: fix request of incorrect number of IRQ vectorsArthur Kiyanovski
Bug: In short the main issue is caused by the fact that the number of queues is changed using ethtool after ena_probe() has been called and before ena_up() was executed. Here is the full scenario in detail: * ena_probe() is called when the driver is loaded, the driver is not up yet at the end of ena_probe(). * The number of queues is changed -> io_queue_count is changed as well - ena_up() is not called since the "dev_was_up" boolean in ena_update_queue_count() is false. * ena_up() is called by the kernel (it's called asynchronously some time after ena_probe()). ena_setup_io_intr() is called by ena_up() and it uses io_queue_count to get the suitable irq lines for each msix vector. The function ena_request_io_irq() is called right after that and it uses msix_vecs - This value only changes during ena_probe() and ena_restore() - to request the irq vectors. This results in "Failed to request I/O IRQ" error for i > io_queue_count. Numeric example: * After ena_probe() io_queue_count = 8, msix_vecs = 9. * The number of queues changes to 4 -> io_queue_count = 4, msix_vecs = 9. * ena_up() is executed for the first time: ** ena_setup_io_intr() inits the vectors only up to io_queue_count. ** ena_request_io_irq() calls request_irq() and fails for i = 5. How to reproduce: simply run the following commands: sudo rmmod ena && sudo insmod ena.ko; sudo ethtool -L eth1 combined 3; Fix: Use ENA_MAX_MSIX_VEC(adapter->num_io_queues + adapter->xdp_num_queues) instead of adapter->msix_vecs. We need to take XDP queues into consideration as they need to have msix vectors assigned to them as well. Note that the XDP cannot be attached before the driver is up and running but in XDP mode the issue might occur when the number of queues changes right after a reset trigger. The ENA_MAX_MSIX_VEC simply adds one to the argument since the first msix vector is reserved for management queue.

2020-03-17net: ena: fix incorrect setting of the number of msix vectorsArthur Kiyanovski
Overview: We don't frequently change the msix vectors throughout the life cycle of the driver. We do so in two functions: ena_probe() and ena_restore(). ena_probe() is only called when the driver is loaded. ena_restore() on the other hand is called during device reset / resume operations. We use num_io_queues for calculating and allocating the number of msix vectors. At ena_probe() this value is equal to max_num_io_queues and thus this is not an issue, however ena_restore() might be called after the number of io queues has changed. A possible bug scenario is as follows: * Change number of queues from 8 to 4. (num_io_queues = 4, max_num_io_queues = 8, msix_vecs = 9,) * Trigger reset occurs -> ena_restore is called. (num_io_queues = 4, max_num_io_queues =8 , msix_vecs = 5) * Change number of queues from 4 to 6. (num_io_queues = 6, max_num_io_queues = 8, msix_vecs = 5) * The driver will reset due to failure of check_for_rx_interrupt_queue() Fix: This can be easily fixed by always using max_num_io_queues to init the msix_vecs, since this number won't change as opposed to num_io_queues.

2020-03-17nfp: allow explicitly selected delayed statsJakub Kicinski
NFP flower offload uses delayed stats. Kernel recently gained the ability to specify stats types. Make nfp accept DELAYED stats, not just the catch all "any". Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-17net: rename flow_action_hw_stats_types* -> flow_action_hw_stats*Jakub Kicinski
flow_action_hw_stats_types_check() helper takes one of the FLOW_ACTION_HW_STATS_*_BIT values as input. If we align the arguments to the opening bracket of the helper there is no way to call this helper and stay under 80 characters. Remove the "types" part from the new flow_action helpers and enum values. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-17net: bcmgenet: keep MAC in reset until PHY is upDoug Berger
As noted in commit 28c2d1a7a0bf ("net: bcmgenet: enable loopback during UniMAC sw_reset") the UniMAC must be clocked at least 5 cycles while the sw_reset is asserted to ensure a clean reset. That commit enabled local loopback to provide an Rx clock from the GENET sourced Tx clk. However, when connected in MII mode the Tx clk is sourced by the PHY so if an EPHY is not supplying clocks (e.g. when the link is down) the UniMAC does not receive the necessary clocks. This commit extends the sw_reset window until the PHY reports that the link is up thereby ensuring that the clocks are being provided to the MAC to produce a clean reset. One consequence is that if the system attempts to enter a Wake on LAN suspend state when the PHY link has not been active the MAC may not have had a chance to initialize cleanly. In this case, we remove the sw_reset and enable the WoL reception path as normal with the hope that the PHY will provide the necessary clocks to drive the WoL blocks if the link becomes active after the system has entered suspend.

2020-03-17Revert "net: bcmgenet: use RGMII loopback for MAC reset"Doug Berger
This reverts commit 3a55402c93877d291b0a612d25edb03d1b4b93ac. This is not a good solution when connecting to an external switch that may not support the isolation of the TXC signal resulting in output driver contention on the pin. A different solution is necessary. Signed-off-by: Doug Berger <opendmb@gmail.com> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-03-17net: phy: improve phy_driver callback handle_interruptHeiner Kallweit
did_interrupt() clears the interrupt, therefore handle_interrupt() can not check which event triggered the interrupt. To overcome this constraint and allow more flexibility for customer interrupt handlers, let's decouple handle_interrupt() from parts of the phylib interrupt handling. Custom interrupt handlers now have to implement the did_interrupt() functionality in handle_interrupt() if needed. Fortunately we have just one custom interrupt handler so far (in the mscc PHY driver), convert it to the changed API. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
