2025-05-21selftests: harness: Remove dependency on libatomicThomas Weißschuh
__sync_bool_compare_and_swap() is deprecated and requires libatomic on GCC. Compiler toolchains don't necessarily have libatomic available, so avoid this requirement by using atomics that don't need libatomic.

2025-05-21selftests: harness: Mark functions without prototypes staticThomas Weißschuh
With -Wmissing-prototypes the compiler will warn about non-static functions which don't have a prototype defined. As they are not used from a different compilation unit they don't need to be defined globally. Avoid the issue by marking the functions static.

2025-05-21tools/nolibc: include nolibc.h early from all header filesThomas Weißschuh
Inclusion of any nolibc header file should also bring all other headers. On the other hand it should also be possible to include any nolibc header files in any order. Currently this is implemented by including the catch-all nolibc.h after the headers own definitions. This is problematic if one nolibc header depends on another one. The first header has to include the other one before defining any symbols. That in turn will include the rest of nolibc while the current header has not defined anything yet. If any other part of nolibc depends on definitions from the current header, errors are encountered. This is already the case today. Effectively nolibc can only be included in the order of nolibc.h. Restructure the way "nolibc.h" is included. Move it to the beginning of the header files and before the include guards. Now any header will behave exactly like "nolibc.h" while the include guards prevent any duplicate definitions.

2025-05-21nvme: avoid creating multipath sysfs group under namespace path devicesNilay Shroff
Commit 4dbd2b2ebe4c ("nvme-multipath: Add visibility for round-robin io-policy") introduced the creation of the multipath sysfs group under the NVMe head gendisk device node. However, it also inadvertently added the same sysfs group under each namespace path device which head node refers to and that is incorrect. The multipath sysfs group should only be exposed through the namespace head gendisk node. This is sufficient, as the head device already provides symbolic links to the individual namespace paths it manages. This patch fixes the issue by preventing the creation of the multipath sysfs group under namespace path devices, ensuring it only appears under the head disk node.

2025-05-21wifi: mt76: mt76x2: Add support for LiteOn WN4516R,WN4519RHenk Vergonet
Adds support for: - LiteOn WN4516R - LiteOn WN4519R Both use: - A nonstandard USB connector - Mediatek chipset MT7600U - ASIC revision: 76320044 Disabled VHT support on ASIC revision 76320044: This fixes the 5G connectibity issue on LiteOn WN4519R module see https://github.com/openwrt/mt76/issues/971 And may also fix the 5G issues on the XBox One Wireless Adapter see https://github.com/openwrt/mt76/issues/200 I have looked at the FCC info related to the MT7632U chip as mentioned in here: https://github.com/openwrt/mt76/issues/459 These confirm the chipset does not support 'ac' mode and hence VHT should be turned of.

2025-05-21wifi: mt76: mt7996: prevent uninit return in mt7996_mac_sta_add_linksQasim Ijaz
If link_conf_dereference_protected() or mt7996_vif_link() or link_sta_dereference_protected() fail the code jumps to the error_unlink label and returns ret which is uninitialised. Fix this by setting err before jumping to error_unlink.

2025-05-21Revert "wifi: mt76: mt7996: fill txd by host driver"Shayne Chen
This reverts commit 3b522cadedfe6e9e0e8193d7d4ab5aa8d0c73209. The MTK connac3 has introduced new hardware, SDO (Software Defined Offload), to offload the process of filling the TX descriptor. Initially, there were some issues, but after several fixes, it should now be stable, allowing us to revert this commit. Additionally, activating SDO is essential for the proper functioning of features like TX checksum offload.
