Backport a5a441ae283d ("ice/ptp: fix crosstimestamp reporting")

by Markus Blöchl

Hi Greg, please consider backporting a5a441ae283d ("ice/ptp: fix crosstimestamp reporting") into linux-6.12.y It fixes a regression from the series around d4bea547ebb57 ("ice/ptp: Remove convert_art_to_tsc()") which affected multiple drivers and occasionally caused phc2sys to fail on ioctl(fd, PTP_SYS_OFFSET_PRECISE, ...). This was the initial fix for ice but apparently tagging it for stable was forgotten during submission. A similar fix for e1000e can be found here: Link: https://lore.kernel.org/lkml/20250709-e1000e_crossts-v2-1-2aae94384c59@bloc… The hunk was moved around slightly in the upstream commit 92456e795ac6 ("ice: Add unified ice_capture_crosststamp"). Let me know if you therefore want a separate patch, I just didn't want to to steal the credits here. Thanks a lot! Markus --

[PATCH 1/2] nvmem: layouts: u-boot-env: remove crc32 endianness conversion

by srini＠kernel.org

From: "Michael C. Pratt" <mcpratt(a)pm.me> On 11 Oct 2022, it was reported that the crc32 verification of the u-boot environment failed only on big-endian systems for the u-boot-env nvmem layout driver with the following error. Invalid calculated CRC32: 0x88cd6f09 (expected: 0x096fcd88) This problem has been present since the driver was introduced, and before it was made into a layout driver. The suggested fix at the time was to use further endianness conversion macros in order to have both the stored and calculated crc32 values to compare always represented in the system's endianness. This was not accepted due to sparse warnings and some disagreement on how to handle the situation. Later on in a newer revision of the patch, it was proposed to use cpu_to_le32() for both values to compare instead of le32_to_cpu() and store the values as __le32 type to remove compilation errors. The necessity of this is based on the assumption that the use of crc32() requires endianness conversion because the algorithm uses little-endian, however, this does not prove to be the case and the issue is unrelated. Upon inspecting the current kernel code, there already is an existing use of le32_to_cpu() in this driver, which suggests there already is special handling for big-endian systems, however, it is big-endian systems that have the problem. This, being the only functional difference between architectures in the driver combined with the fact that the suggested fix was to use the exact same endianness conversion for the values brings up the possibility that it was not necessary to begin with, as the same endianness conversion for two values expected to be the same is expected to be equivalent to no conversion at all. After inspecting the u-boot environment of devices of both endianness and trying to remove the existing endianness conversion, the problem is resolved in an equivalent way as the other suggested fixes. Ultimately, it seems that u-boot is agnostic to endianness at least for the purpose of environment variables. In other words, u-boot reads and writes the stored crc32 value with the same endianness that the crc32 value is calculated with in whichever endianness a certain architecture runs on. Therefore, the u-boot-env driver does not need to convert endianness. Remove the usage of endianness macros in the u-boot-env driver, and change the type of local variables to maintain the same return type. If there is a special situation in the case of endianness, it would be a corner case and should be handled by a unique "compatible". Even though it is not necessary to use endianness conversion macros here, it may be useful to use them in the future for consistent error printing.

[6.6.y] ipv6: make addrconf_wq single threaded

by Brett A C Sheffield

TL;DR - please backport dfd2ee086a63c730022cb095576a8b3a5a752109 "ipv6: make addrconf_wq single threaded" to 6.6.y (only). When testing the stable and LTS kernels this week I noticed one of our tests was failing on the 6.6.y kernels and passing on both newer and older stable kernels as well as mainline. It is not a perfect test. Running the test in a tight loop, it would occasionally fail on other kernels after thousands of iterations (6k-10k). However, on 6.6.y it usually fails on the first or second run, so I thought it was worth digging a bit. I've bisected the behaviour change back to: 86bfbb7ce4f67a88df2639198169b685668e7349 "sched/fair: Add lag based placement" The regression is later fixed by completely unrelated commit: dfd2ee086a63c730022cb095576a8b3a5a752109 "ipv6: make addrconf_wq single threaded" ie. a change to the scheduler caused the change in behaviour, and changing ipv6 addrconf to use a single-threaded workqueue seems to have "fixed" it. The original test is creating three tap interfaces, binding a socket to each and sending a packet on each. It's a simple test just to check that binding a socket to an interface works with our API. I wrote a simplified test, which just: - creates a single TAP interface, disables DAD, and brings it up - times how long before a single IPv6 packet can be sent without error These are the results for the commit (e0c2ff903c32) before the change: 2025-07-18 07:01:33-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:35-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:37-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:01:39-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:40-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 2306 tries (0.00296s) 2025-07-18 07:01:47-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:49-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:01:50-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:52-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:53-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:01:59-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:02:00-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:02:01-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:03-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:05-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 2042 tries (0.00266s) 2025-07-18 07:05:07-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:05:09-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) 2025-07-18 07:05:11-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00003s) 2025-07-18 07:05:12-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00004s) 2025-07-18 07:05:15-00:00 6.5.0-rc2-00017-ge0c2ff903c32 8 bytes sent after 1 tries (0.00002s) ie. sending mostly succeeds on the first attempt after TAP creation, with occasional outliers.

There is a race if indio_dev exits buffer mode in the middle of the interrupt that flushes the fifo. Fix this by calling synchronize_irq() to ensure that no interrupt is currently running when disabling buffer mode.
