ip_finish_output_gso() may call .ndo_features_check() even before the skb has a L2 header. This conflicts with qeth_get_ip_version()'s attempt to inspect the L2 header via vlan_eth_hdr().

Due to insufficient locking, qeth_core_set_online() and qeth_dev_layer2_store() can run in parallel, both attempting to load & setup the discipline (and stepping on each other toes along the way). A similar race can also occur between qeth_core_remove_device() and qeth_dev_layer2_store(). Access to .discipline is meant to be protected by the discipline_mutex, so add/expand the locking in qeth_core_remove_device() and qeth_core_set_online(). Adjust the locking in qeth_l*_remove_device() accordingly, as it's now handled by the callers in a consistent manner. Based on an initial patch by Ursula Braun.

When qeth_dev_layer2_store() - holding the discipline_mutex - waits inside qeth_l*_remove_device() for a qeth_do_reset() thread to complete, we can hit a deadlock if qeth_do_reset() concurrently calls qeth_set_online() and thus tries to aquire the discipline_mutex. Move the discipline_mutex locking outside of qeth_set_online() and qeth_set_offline(), and turn the discipline into a parameter so that callers understand the dependency. To fix the deadlock, we can now relax the locking: As already established, qeth_l*_remove_device() waits for qeth_do_reset() to complete. So qeth_do_reset() itself is under no risk of having card->discipline ripped out while it's running, and thus doesn't need to take the discipline_mutex.

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.

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.

This means we are not overwriting the configuration for the third port (port two since we start counting from zero) with the settings for the sixth port (with number five) anymore.
