2021-04-24include/sys/personality.h: resync with glibcThomas Petazzoni
The trigger for this resync was ADDR_NO_RANDOMIZE, which was not defined in uClibc-ng, but is used for example by the uftrace project. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
2021-04-18libpthread/nptl: create timer thread with sufficiant stack size (account for ↵Peter Seiderer
TLS) Create timer thread with sufficiant stack size (take into account allocated space for thread-local-storage), for this backport glibc commit 'Create internal threads with sufficient stack size' ([1], [2]) introducing __pthread_get_minstack() and use it in __start_helper_thread(). Fixes timer_create() in case of linking with library using large TLS area (e.g openblas, see [3]).

2021-04-09open: Add support for O_TMPFILENicolas Cavallari
Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY) to make it fail on old kernels. Copying definitions from glibc for O_TMPFILE is not enough to support O_TMPFILE; The open() wrapper also need to pass the mode when the flag contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed but yield unexpected results. openat() is curiously not affected since it passes the mode unconditionally..

2021-01-27sh: Add 64-bit time types from kernelGeoffrey Le Gourriérec
Building uclibc 1.0.37 for SuperH architecture with linux-headers 5.10.7 fails at libpthread level due to missing time-related data structures, usually defined by the kernel. Define those missing data structures in SuperH-specific kernel_types.h. Context: building for sh4eb-r2d[1] and sh4-r2d[1] boards emulations for QEMU using the buildroot image generation tool. Regarding the issue, a patch[3] was already issued in the kernel some time ago, which aimed to solve precisely this problem. After coming up with a quick and dirty patch for buildroot modifying Linux headers[4], some discussion was sparked on the subject with Linux folks[5]. Some analyzing later, conclusion was that: 1) Previously mentioned patch[4] was fixing the symptom, not the ill 2) SuperH-specific code in uclibc could be patched instead, to solve the problem for other use cases (e.g. building just a toolchain) [1] https://git.buildroot.net/buildroot/tree/configs/qemu_sh4eb_r2d_defconfig?h=2020.02.9 [2] https://git.buildroot.net/buildroot/tree/configs/qemu_sh4_r2d_defconfig?h=2020.02.9 [3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc94cf2092c7c1267fa2deb8388d624f50eba808 [4] https://git.buildroot.net/buildroot/commit/?id=742f37de8d0e3797698411dfc6a63bd7e98aafe2 [5] https://patchwork.kernel.org/project/linux-sh/patch/20210123165652.10884-1-geoffrey.legourrierec@gmail.com/ Signed-off-by: Geoffrey Le Gourriérec <geoffrey.legourrierec@gmail.com>

2020-12-23stdlib: fix potential UB and integer overflow with huge allocations using ↵Yann Sionneau
malloc-simple allocator Two things are fixed by this commit: 1/ It is wrong to allocate an object of size > PTRDIFF_MAX. It is explained in this thread: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63303 2/ There was a possible integer overflow in both malloc() and memalign() implementations of stdlib/malloc-simple. The malloc() integer overflow issue is fixed by the side effect of fixing the PTRDIFF_MAX issue. The memalign() one is fixed by adding a comparison. Signed-off-by: Yann Sionneau <yann@sionneau.net>

Previous implementation was respecting the man page description of what the function should do. Also the function does not seem to be defined by POSIX. But... to be really useful the function needs to handle option matching and not just substring matching. This is copy pasted from glibc.

2020-09-15Fix memory corruption due to struct stat fieldYann Sionneau
Kernel stat/stat64 structure and uClibc-ng ones were not in sync regarding the timespec fields. Kernel had them but uClibc did not expose it in some cases. Man page says that stat struct should have timespec fields if: * _POSIX_C_SOURCE is defined to 200809L or greater or * _XOPEN_SOURCE is defined to 700 or greater or * _BSD_SOURCE is defined or * _SVID_SOURCE is defined In the case of buildroot vim build, neither _BSD_SOURCE nor _SVID_SOURCE were defined. Only _POSIX_C_SOURCE and _XOPEN_SOURCE were defined. uClibc-ng header only checked for _BSD_SOURCE and _SVID_SOURCE via __USE_MISC. This patch adds a check to __USE_XOPEN2K8 which is defined if _POSIX_C_SOURCE >= 200809L or _XOPEN_SOURCE >= 700 This for instance fixes a crash at startup of vim (not the busybox one) on aarch64 and all other arch where in kernel STAT_HAVE_NSEC is set and where stat.h in uClibc-ng comes from libc/sysdeps/linux/common-generic/bits Signed-off-by: Yann Sionneau <ysionneau@kalray.eu>

2020-09-13utils/getconf: Fix compilation errorDamien Le Moal
In the main() function, all cases of the "switch (specs[i].num)" switch-case are all conditionally defined. Depending on the target environementi, none of them may endup being defined, resulting in the code block before the no-op default case to generate a "warning: statement will never be executed" compilation error. Avoid this by conditionally defining this code block with the macro DO_GETCONF_NAME which is itself defined if any of the switc cases is defined too.
