2021-07-30can: esd_usb2: fix memory leakPavel Skripkin1-1/+15
In esd_usb2_setup_rx_urbs() MAX_RX_URBS coherent buffers are allocated and there is nothing, that frees them: 1) In callback function the urb is resubmitted and that's all 2) In disconnect function urbs are simply killed, but URB_FREE_BUFFER is not set (see esd_usb2_setup_rx_urbs) and this flag cannot be used with coherent buffers. So, all allocated buffers should be freed with usb_free_coherent() explicitly. Side note: This code looks like a copy-paste of other can drivers. The same patch was applied to mcba_usb driver and it works nice with real hardware. There is no change in functionality, only clean-up code for coherent buffers.

2021-07-30can: mcba_usb_start(): add missing urb->transfer_dma initializationPavel Skripkin1-0/+2
Yasushi reported, that his Microchip CAN Analyzer stopped working since commit 91c02557174b ("can: mcba_usb: fix memory leak in mcba_usb"). The problem was in missing urb->transfer_dma initialization. In my previous patch to this driver I refactored mcba_usb_start() code to avoid leaking usb coherent buffers. To archive it, I passed local stack variable to usb_alloc_coherent() and then saved it to private array to correctly free all coherent buffers on ->close() call. But I forgot to initialize urb->transfer_dma with variable passed to usb_alloc_coherent(). All of this was causing device to not work, since dma addr 0 is not valid and following log can be found on bug report page, which points exactly to problem described above. | DMAR: [DMA Write] Request device [00:14.0] PASID ffffffff fault addr 0 [fault reason 05] PTE Write access is not set Fixes: 91c02557174b ("can: mcba_usb: fix memory leak in mcba_usb") Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990850 Link: https://lore.kernel.org/r/20210725103630.23864-1-paskripkin@gmail.com Cc: linux-stable <stable@vger.kernel.org> Reported-by: Yasushi SHOJI <yasushi.shoji@gmail.com> Signed-off-by: Pavel Skripkin <paskripkin@gmail.com> Tested-by: Yasushi SHOJI <yashi@spacecubics.com> [mkl: fixed typos in commit message - thanks Yasushi SHOJI] Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

2021-07-27net/mlx5e: Fix nullptr in mlx5e_hairpin_get_mdev()Dima Chumak1-2/+31
The result of __dev_get_by_index() is not checked for NULL and then gets dereferenced immediately. Also, __dev_get_by_index() must be called while holding either RTNL lock or @dev_base_lock, which isn't satisfied by mlx5e_hairpin_get_mdev() or its callers. This makes the underlying hlist_for_each_entry() loop not safe, and can have adverse effects in itself. Fix by using dev_get_by_index() and handling nullptr return value when ifindex device is not found. Update mlx5e_hairpin_get_mdev() callers to check for possible PTR_ERR() result.

2021-07-27net/mlx5e: RX, Avoid possible data corruption when relaxed ordering and LRO ↵Tariq Toukan1-1/+10
combined When HW aggregates packets for an LRO session, it writes the payload of two consecutive packets of a flow contiguously, so that they usually share a cacheline. The first byte of a packet's payload is written immediately after the last byte of the preceding packet. In this flow, there are two consecutive write requests to the shared cacheline: 1. Regular write for the earlier packet. 2. Read-modify-write for the following packet. In case of relaxed-ordering on, these two writes might be re-ordered. Using the end padding optimization (to avoid partial write for the last cacheline of a packet) becomes problematic if the two writes occur out-of-order, as the padding would overwrite payload that belongs to the following packet, causing data corruption. Avoid this by disabling the end padding optimization when both LRO and relaxed-ordering are enabled.

2021-07-25octeontx2-pf: Fix interface down flag on errorGeetha sowjanya2-4/+8
In the existing code while changing the number of TX/RX queues using ethtool the PF/VF interface resources are freed and reallocated (otx2_stop and otx2_open is called) if the device is in running state. If any resource allocation fails in otx2_open, driver free already allocated resources and return. But again, when the number of queues changes as the device state still running oxt2_stop is called. In which we try to free already freed resources leading to driver crash. This patch fixes the issue by setting the INTF_DOWN flag on error and free the resources in otx2_stop only if the flag is not set.

2021-07-25octeontx2-af: Fix PKIND overlap between LBK and LMAC interfacesGeetha sowjanya3-4/+11
Currently PKINDs are not assigned to LBK channels. The default value of LBK_CHX_PKIND (channel to PKIND mapping) register is zero, which is resulting in a overlap of pkind between LBK and CGX LMACs. When KPU1 parser config is modified when PTP timestamping is enabled on the CGX LMAC interface it is impacting traffic on LBK interfaces as well. This patch fixes the issue by reserving the PKIND#0 for LBK devices. CGX mapped PF pkind starts from 1 and also fixes the max pkind available.

2021-07-24can: mcp251xfd: mcp251xfd_irq(): stop timestamping worker in case error in IRQMarc Kleine-Budde1-0/+1
In case an error occurred in the IRQ handler, the chip status is dumped via devcoredump and all IRQs are disabled, but the chip stays powered for further analysis. The chip is in an undefined state and will not receive any CAN frames, so shut down the timestamping worker, which reads the TBC register regularly, too. This avoids any CRC read error messages if there is a communication problem with the chip.
