mlx5e_create_ttc_table_groups() frees ft->g on failure of kvzalloc(), but such failure will be caught by its caller in mlx5e_create_ttc_table() and ft->g will be freed again in mlx5e_destroy_flow_table(). The same issue also occurs in mlx5e_create_ttc_table_groups(). Set ft->g to NULL after kfree() to avoid double free.

Prior to this patch, configuring speed to 50G with autoneg off over devices supporting 50G per lane failed. Support for 50G per lane introduced a new set of link-modes, on which driver always performed a speed validation as if only legacy link-modes were configured.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change. These tests explicitly test for a recently discovered problem in the IPv6 routing framework where PMTU exceptions were not properly released when replacing a route via "ip route change ...". After creating PMTU exceptions, the route from the device A to R1 will be replaced with a new route, then device A will be deleted. If the PMTU exceptions were properly cleaned up by the kernel, this device deletion will succeed. Otherwise, the unregistration of the device will stall, and messages such as the following will be logged in dmesg: unregister_netdevice: waiting for veth_A-R1 to become free.

Route removal is handled by two code paths. The main removal path is via fib6_del_route() which will handle purging any PMTU exceptions from the cache, removing all per-cpu copies of the DST entry used by the route, and releasing the fib6_info struct. The second removal location is during fib6_add_rt2node() during a route replacement operation. This path also calls fib6_purge_rt() to handle cleaning up the per-cpu copies of the DST entries and releasing the fib6_info associated with the older route, but it does not flush any PMTU exceptions that the older route had. Since the older route is removed from the tree during the replacement, we lose any way of accessing it again. As these lingering DSTs and the fib6_info struct are holding references to the underlying netdevice struct as well, unregistering that device from the kernel can never complete.

The previous patch fixes a TEF vs. TX race condition, by first updating the TEF tail pointer in hardware, and then updating the driver internal pointer. The same pattern exists in the RX-path, too. This should be no problem, as the driver accesses the RX-FIFO from the interrupt handler only, thus the access is properly serialized. Fix the order here, too, so that the TEF- and RX-path look similar.

The mcp251xfd driver uses a TX FIFO for sending CAN frames and a TX Event FIFO (TEF) for completed TX-requests. The TEF event handling in the mcp251xfd_handle_tefif() function has a race condition. It first increments the tx-ring's tail counter to signal that there's room in the TX and TEF FIFO, then it increments the TEF FIFO in hardware. A running mcp251xfd_start_xmit() on a different CPU might not stop the txqueue (as the tx-ring still shows free space). The next mcp251xfd_start_xmit() will push a message into the chip and the TX complete event might overflow the TEF FIFO. This patch changes the order to fix the problem.

Aligning to tx_ndp_modulus is not sufficient because the next align call can be cdc_ncm_align_tail, which can add up to ctx->tx_modulus + ctx->tx_remainder - 1 bytes. This used to lead to occasional crashes on a Huawei 909s-120 LTE module as follows: - the condition marked /* if there is a remaining skb [...] */ is true so the swaps happen - skb_out is set from ctx->tx_curr_skb - skb_out->len is exactly 0x3f52 - ctx->tx_curr_size is 0x4000 and delayed_ndp_size is 0xac (note that the sum of skb_out->len and delayed_ndp_size is 0x3ffe) - the for loop over n is executed once - the cdc_ncm_align_tail call marked /* align beginning of next frame */ increases skb_out->len to 0x3f56 (the sum is now 0x4002) - the condition marked /* check if we had enough room left [...] */ is false so we break out of the loop - the condition marked /* If requested, put NDP at end of frame. */ is true so the NDP is written into skb_out - now skb_out->len is 0x4002, so padding_count is minus two interpreted as an unsigned number, which is used as the length argument to memset, leading to a crash with various symptoms but usually including > Call Trace: > <IRQ> > cdc_ncm_fill_tx_frame+0x83a/0x970 [cdc_ncm] > cdc_mbim_tx_fixup+0x1d9/0x240 [cdc_mbim] > usbnet_start_xmit+0x5d/0x720 [usbnet] The cdc_ncm_align_tail call first aligns on a ctx->tx_modulus boundary (adding at most ctx->tx_modulus-1 bytes), then adds ctx->tx_remainder bytes. Alternatively, the next alignment call can occur in cdc_ncm_ndp16 or cdc_ncm_ndp32, in which case at most ctx->tx_ndp_modulus-1 bytes are added. A similar problem has occurred before, and the code is nontrivial to reason about, so add a guard before the crashing call. By that time it is too late to prevent any memory corruption (we'll have written past the end of the buffer already) but we can at least try to get a warning written into an on-disk log by avoiding the hard crash caused by padding past the buffer with a huge number of zeros.

Samuel Holland says: ==================== Fixes for dwmac-sun8i suspend/resume This series fixes issues preventing dwmac-sun8i from working after a suspend/resume cycle. Those issues include the PHY being left powered off, the MAC syscon configuration being reset, and the reference to the reset controller being improperly dropped. They also fix related issues in probe error handling and driver removal. ==================== Signed-off-by: -
Samuel Holland authored
Previously, sun8i_dwmac_set_syscon was called from a chain of functions in several different files: sun8i_dwmac_probe stmmac_dvr_probe stmmac_hw_init stmmac_hwif_init sun8i_dwmac_setup sun8i_dwmac_set_syscon which made the lifetime of the syscon values hard to reason about. Part of the problem is that there is no similar platform driver callback from stmmac_dvr_remove. As a result, the driver unset the syscon value in sun8i_dwmac_exit, but this leaves it uninitialized after a suspend/ resume cycle. It was also unset a second time (outside sun8i_dwmac_exit) in the probe error path. Move the init to the earliest available place in sun8i_dwmac_probe (after stmmac_probe_config_dt, which initializes plat_dat), and the deinit to the corresponding position in the cleanup order. Since priv is not filled in until stmmac_dvr_probe, this requires changing the sun8i_dwmac_set_syscon parameters to priv's two relevant members.

While stmmac_pltfr_remove calls sun8i_dwmac_exit, the sun8i_dwmac_init and sun8i_dwmac_exit functions are also called by the stmmac_platform suspend/resume callbacks. They may be called many times during the device's lifetime and should not release resources used by the driver. Furthermore, there was no error handling in case registering the MDIO mux failed during probe, and the EPHY clock was never released at all. Fix all of these issues by moving the deinitialization code to a driver removal callback. Also ensure the EPHY is powered down before removal.

stmmac_pltfr_remove does three things in one function, making it inapproprate for unwinding the steps in the probe function. Currently, a failure before the call to stmmac_dvr_probe would leak OF node references due to missing a call to stmmac_remove_config_dt.

A call to dma_alloc_coherent() is wrapped by sonic_alloc_descriptors(). This is correctly freed in the remove function, but not in the error handling path of the probe function. Fix this by adding the missing dma_free_coherent() call. While at it, rename a label in order to be slightly more informative.
