ath10k: Fix the MTU size on QCA9377 SDIO

2022-01-27T09:54:36Z

commit 09b8cd69edcf2be04a781e1781e98e52a775c9ad upstream. On an imx6dl-pico-pi board with a QCA9377 SDIO chip, simply trying to connect via ssh to another machine causes: [ 55.824159] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [ 55.832169] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [ 55.838529] ath10k_sdio mmc1:0001:1: failed to push frame: -12 [ 55.905863] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [ 55.913650] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [ 55.919887] ath10k_sdio mmc1:0001:1: failed to push frame: -12 , leading to an ssh connection failure. One user inspected the size of frames on Wireshark and reported the followig: "I was able to narrow the issue down to the mtu. If I set the mtu for the wlan0 device to 1486 instead of 1500, the issue does not happen. The size of frames that I see on Wireshark is exactly 1500 after setting it to 1486." Clearing the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE avoids the problem and the ssh command works successfully after that. Introduce a 'credit_size_workaround' field to ath10k_hw_params for the QCA9377 SDIO, so that the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE is not set in this case. Tested with QCA9377 SDIO with firmware WLAN.TF.1.1.1-00061-QCATFSWPZ-1.

mtd: nand: bbt: Fix corner case in bad block table handling

2022-01-27T09:54:36Z

commit fd0d8d85f7230052e638a56d1bfea170c488e6bc upstream. In the unlikely event that both blocks 10 and 11 are marked as bad (on a 32 bit machine), then the process of marking block 10 as bad stomps on cached entry for block 11. There are (of course) other examples.

mm/hmm.c: allow VM_MIXEDMAP to work with hmm_range_fault

2022-01-27T09:54:36Z

commit 87c01d57fa23de82fff593a7d070933d08755801 upstream. hmm_range_fault() can be used instead of get_user_pages() for devices which allow faulting however unlike get_user_pages() it will return an error when used on a VM_MIXEDMAP range. To make hmm_range_fault() more closely match get_user_pages() remove this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL case in hmm_vma_handle_pte(). Rather than replicating the logic of vm_normal_page() call it directly and do a check for the zero pfn similar to what get_user_pages() currently does. Also add a test to hmm selftest to verify functionality.

commit 99218cbf81bf21355a3de61cd46a706d36e900e6 upstream. platform_get_irq() returns negative error number instead 0 on failure. And the doc of platform_get_irq() provides a usage example: int irq = platform_get_irq(pdev, 0); if (irq < 0) return irq; Fix the check of return value to catch errors correctly.

scripts/dtc: dtx_diff: remove broken example from help text

2022-01-27T09:54:35Z

commit d8adf5b92a9d2205620874d498c39923ecea8749 upstream. dtx_diff suggests to use <(...) syntax to pipe two inputs into it, but this has never worked: The /proc/self/fds/... paths passed by the shell will fail the `[ -f "${dtx}" ] && [ -r "${dtx}" ]` check in compile_to_dts, but even with this check removed, the function cannot work: hexdump will eat up the DTB magic, making the subsequent dtc call fail, as a pipe cannot be rewound. Simply remove this broken example, as there is already an alternative one that works fine.
