tools/nolibc/stdio: let perror work when NOLIBC_IGNORE_ERRNO is set

2026-01-11T14:18:20+00:00

[ Upstream commit c485ca3aff2442adea4c08ceb5183e671ebed22a ] There is no errno variable when NOLIBC_IGNORE_ERRNO is defined. As such, simply print the message with "unknown error" rather than the integer value of errno.

objtool: Fix find_{symbol,func}_containing()

[ Upstream commit 5da6aea375cde499fdfac3cde4f26df4a840eb9f ] The current find_{symbol,func}_containing() functions are broken in the face of overlapping symbols, exactly the case that is needed for a new ibt/endbr supression. Import interval_tree_generic.h into the tools tree and convert the symbol tree to an interval tree to support proper range stabs.

asm-generic: Unify uapi bitsperlong.h for arm64, riscv and loongarch

2025-12-06T21:12:34+00:00

[ Upstream commit 8386f58f8deda81110283798a387fb53ec21957c ] Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, it is probably fine to unify the definition of __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h. In order to keep safe and avoid regression, only unify uapi bitsperlong.h for some archs such as arm64, riscv and loongarch which are using newer toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

tools bitmap: Add missing asm-generic/bitsperlong.h include

[ Upstream commit f38ce0209ab4553906b44bd1159e35c740a84161 ] small_const_nbits is defined in asm-generic/bitsperlong.h which bitmap.h uses but doesn't include causing build failures in some build systems. Add the missing #include. Note the bitmap.h in tools has diverged from that of the kernel, so no changes are made there.

tools/nolibc: make time_t robust if __kernel_old_time_t is missing in host headers

2025-10-15T09:56:29+00:00

[ Upstream commit 0ff52df6b32a6b04a7c9dfe3d7a387aff215b482 ] Commit d5094bcb5bfd ("tools/nolibc: define time_t in terms of __kernel_old_time_t") made nolibc use the kernel's time type so that `time_t` matches `timespec::tv_sec` on all ABIs (notably x32). But since __kernel_old_time_t is fairly new, notably from 2020 in commit 94c467ddb273 ("y2038: add __kernel_old_timespec and __kernel_old_time_t"), nolibc builds that rely on host headers may fail. Switch to __kernel_time_t, which is the same as __kernel_old_time_t and has existed for longer. Tested in PPC VM of Open Source Lab of Oregon State University (./tools/testing/selftests/rcutorture/bin/mkinitrd.sh) Fixes: d5094bcb5bfd ("tools/nolibc: define time_t in terms of __kernel_old_time_t") Signed-off-by: Zhouyi Zhou [Thomas: Reformat commit and its message a bit] Signed-off-by: Thomas Weißschuh Signed-off-by: Sasha Levin

bonding: Add independent control state machine

2025-08-28T14:26:18+00:00

[ Upstream commit 240fd405528bbf7fafa0559202ca7aa524c9cd96 ] Add support for the independent control state machine per IEEE 802.1AX-2008 5.4.15 in addition to the existing implementation of the coupled control state machine. Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in the LACP MUX state machine for separated handling of an initial Collecting state before the Collecting and Distributing state. This enables a port to be in a state where it can receive incoming packets while not still distributing. This is useful for reducing packet loss when a port begins distributing before its partner is able to collect. Added new functions such as bond_set_slave_tx_disabled_flags and bond_set_slave_rx_enabled_flags to precisely manage the port's collecting and distributing states. Previously, there was no dedicated method to disable TX while keeping RX enabled, which this patch addresses. Note that the regular flow process in the kernel's bonding driver remains unaffected by this patch. The extension requires explicit opt-in by the user (in order to ensure no disruptions for existing setups) via netlink support using the new bonding parameter coupled_control. The default value for coupled_control is set to 1 so as to preserve existing behaviour.

tools/nolibc: fix spelling of FD_SETBITMASK in FD_* macros

commit a477629baa2a0e9991f640af418e8c973a1c08e3 upstream. While nolibc-test does test syscalls, it doesn't test as much the rest of the macros, and a wrong spelling of FD_SETBITMASK in commit feaf75658783a broke programs using either FD_SET() or FD_CLR() without being noticed.

tools/nolibc: define time_t in terms of __kernel_old_time_t

2025-08-28T14:25:53+00:00

[ Upstream commit d5094bcb5bfdfea2cf0de8aaf77cc65db56cbdb5 ] Nolibc assumes that the kernel ABI is using a time values that are as large as a long integer. For most ABIs this holds true. But for x32 this is not correct, as it uses 32bit longs but 64bit times. Also the 'struct stat' implementation of nolibc relies on timespec::tv_sec and time_t being the same type. While timespec::tv_sec comes from the kernel and is of type __kernel_old_time_t, time_t is defined within nolibc. Switch to the __kernel_old_time_t to always get the correct type.

kallsyms: fix build without execinfo

commit a95743b53031b015e8949e845a9f6fdfb2656347 upstream. Some libc's like musl libc don't provide execinfo.h since it's not part of POSIX. In order to fix compilation on musl, only include execinfo.h if available (HAVE_BACKTRACE_SUPPORT) This was discovered with c104c16073b7 ("Kunit to check the longest symbol length") which starts to include linux/kallsyms.h with Alpine Linux' configs.
