2025-05-21tools/nolibc: implement wait() in terms of waitpid()Thomas Weißschuh
Newer architectures like riscv 32-bit are missing sys_wait4(). Make use of the fact that wait(&status) is defined to be equivalent to waitpid(-1, status, 0) to implement it on all architectures.

2025-05-21tools/nolibc: fall back to sys_clock_gettime() in gettimeofday()Thomas Weißschuh
Newer architectures (like riscv32) do not implement sys_gettimeofday(). In those cases fall back to sys_clock_gettime(). While that does not support the timezone argument of sys_gettimeofday(), specifying this argument invokes undefined behaviour, so it's safe to ignore.

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.

2025-05-21tools/nolibc: add target to check header usabilityThomas Weißschuh

2025-05-21efi: zboot specific mechanism for embedding SBAT sectionVitaly Kuznetsov
SBAT is a mechanism which improves SecureBoot revocations of UEFI binaries by introducing a generation-based technique. Compromised or vulnerable UEFI binaries can be prevented from booting by bumping the minimal required generation for the specific component in the bootloader. More information on the SBAT can be obtained here: https://github.com/rhboot/shim/blob/main/SBAT.md Upstream Linux kernel does not currently participate in any way in SBAT as there's no existing policy in how SBAT generation number should be defined. Keep the status quo and provide a mechanism for distro vendors and anyone else who signs their kernel for SecureBoot to include their own SBAT data. This leaves the decision on the policy to the vendor. Basically, each distro implementing SecureBoot today, will have an option to inject their own SBAT data during kernel build and before it gets signed by their SecureBoot CA. Different distro do not need to agree on the common SBAT component names or generation numbers as each distro ships its own 'shim' with their own 'vendor_cert'/'vendor_db' Implement support for embedding SBAT data for architectures using zboot (arm64, loongarch, riscv). Put '.sbat' section in between '.data' and '.text' as the former also covers '.bss' and thus must be the last one.

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: mt7996: rework radar HWRDD idxStanleyYP Wang
The definition of MT_RX_SEL (for rdd_rx_sel) is mixed with the definition of HWRDD idx. For example, MT_RX_SEL2 is for background HWRDD idx, not an option of rdd_rx_sel. Additionally, HWRDD idx does not exactly map to band idx for Connac 3 chips. So, add mt7996_get_rdd_idx as a helper function. Finally, remove some parts of the code inherited from the legacy chips. For instance, 1. rdd_state is used for single-band-dual-HWRDD chips (for 80+80), especially the 76xx series. 2. rdd_rx_sel is also used for single-band-dual-HWRDD chips rx_sel = 0 => RDD0 for WF0, RDD1 for WF2 rx_sel = 1 => RDD0 for WF1, RDD1 for WF3 Chip Variants | 5G rdd idx | Background rdd idx ---------------------------|----------------|------------------- MT7996 (except 205/255) | 1 | 2 MT7992 | 1 | 2 MT7990 | 1 | 2 Signed-off-by: StanleyYP Wang <StanleyYP.Wang@mediatek.com> Reviewed-by: Shayne Chen <shayne.chen@mediatek.com> Reviewed-by: Money Wang <money.wang@mediatek.com> Link: https://patch.msgid.link/20250320015926.3948672-1-StanleyYP.Wang@mediatek.com Signed-off-by: Felix Fietkau <nbd@nbd.name>

Some of the variants do not support background radar, so add a helper to report background radar capability. For mt7916, only the variant of 5G 2T2R + 1R supports background radar.
