on mips Updated config to allow compilation of rcrt1.o for mips and modified it's crt1.S to perform relocates in __start. The mips architecture performs relocations differently then most other architectures. reloc_static_pie was rewritten, taking code from dl-startup.c, in order to perfrom the additional relocations. Modifications were made to mips' dl-startup.h to allow for the use of contained macros without including _start definition. Signed-off-by: linted <linted@users.noreply.github.com>

2022-07-26Added support for creation of Static Position-Independent Executables (PIE) ↵linted
on i386, x86_64, and arm. This patch adds the generation of rcrt1.o which is used by gcc when compiling with the --static-pie flag. rcrt1.o differs from crt1.o and Scrt1.o in that it the executable has a dynamic section but no relocations have been performed prior to _start being called. crt1.o assumes there to be no dynamic relocations, and Scrt1.o has all relocations performed prior to execution by lsdo. The new reloc_static_pie function handles parsing the dynamic section, and performing the relocations in a architecture agnostic method. It also sets _dl_load_base which is used when initalizing TLS to ensure loading from the proper location. This allows for easier porting of static-pie support to additional architectures as only modifications to crt1.S to find the load address are required.

2022-01-10arc: fix signal handler restorerSergey Matyukevich
When MD_FALLBACK_FRAME_STATE_FOR handler in libgcc unwind code checks the second instruction opcode in __default_rt_sa_restorer function, it expects to see the following values for ARC cores: - 0x7ee0781e for ARCv2 LE - 0x003f226f for ARC700 LE ARC700 value correspond to trap0 instruction. ARCv2 value corresponds to the following code: traps_0 j_s [blink] However, unlike glibc, uClibc implementation of __default_rt_sa_restorer for ARC does not have that jump. Hence libgcc unwind code is not able to recognize signal frame correctly on ARCv2 and completes too early. This change fixes libgcc unwinding over signal frame on ARCv2 adding missing jump to __default_rt_sa_restorer. Signed-off-by: Sergey Matyukevich <sergey.matyukevich@synopsys.com>

2021-06-04powerpc: fix PIE/PIC builds with newer gcc/binutils which use secureplt by ↵Yann Sionneau
default This patch fixes segfault of all user space processes (including init, which caused a panic) on recent buildroot powerpc32 builds. The issue has been reported by Romain Naour in this thread: https://mailman.uclibc-ng.org/pipermail/devel/2021-May/002068.html Recent buildroot toolchain enables secure PLT in powerpc gcc. The latter will then supply -msecure-plt to gas invocations by default. Recent buildroot also enables PIE by defaults. For the secure PLT to work in PIC, the r30 register needs to point to the GOT. Old "bss plt" was just a one-instruction-wide PLT slot, pointed-to by a R_PPC_JMP_SLOT relocation, which was written on-the-fly to contain a branch instruction to the correct address. It therefore had to stay writable. New secure PLT only contains read-only code which loads the branch address from the writable GOT. Note: secure PLT without PIC does not need r30 to be set. Because offset between plt stub code and got is known at link-time. In this case the PLT entry looks like: 1009b3e0 <__uClibc_main@plt>: 1009b3e0: 3d 60 10 0e lis r11,4110 1009b3e4: 81 6b 03 74 lwz r11,884(r11) 1009b3e8: 7d 69 03 a6 mtctr r11 1009b3ec: 4e 80 04 20 bctr Whereas secure PLT with PIC - offset between plt and got is unknown at link-time - looks like this: 000af800 <00000000.plt_pic32.__uClibc_main>: af800: 81 7e 03 80 lwz r11,896(r30) af804: 7d 69 03 a6 mtctr r11 af808: 4e 80 04 20 bctr af80c: 60 00 00 00 nop Signed-off-by: Yann Sionneau <yann@sionneau.net>
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>

2020-09-15Fix 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>

2020-01-30poll: avoid calling select with empty sets which hangs the processYann Sionneau
Avoid calling select with empty sets which hangs the process This makes uClibc-ng act like glibc and musl Without this fix the test_poll of python3 testsuite hangs forever Scenario of the issue: If you call poll with only invalid file descriptors, like in python3 testsuite (https://github.com/python/cpython/blob/master/Lib/test/test_poll.py#L83) You will go through uClibc poll emulation code, which is based on select syscall. Your first call to select will fail, it will return -1 and errno will be set to EBADF: https://github.com/wbx-github/uclibc-ng/blob/master/libc/sysdeps/linux/common/poll.c#L120 Then you will go through the for loop which tests individually each file descriptor by calling select on each one: https://github.com/wbx-github/uclibc-ng/blob/master/libc/sysdeps/linux/common/poll.c#L163 each call will also return -1 with errno being equal to EBADF. Therefore all pollfd will have the POLLNVAL flag in their respective revents field. And, the most important, rset/wset/xset will stay empty. Then the for loop ends, the "continue" makes the while loop run again. The following select() is run again: https://github.com/wbx-github/uclibc-ng/blob/master/libc/sysdeps/linux/common/poll.c#L120 But this time the sets are empty. If the poll was called with timeout set to -1, this select will hang forever because there is no timeout and the sets are empty so no event will ever wake it up. test program: int main(void) { struct pollfd pfd; int ret; int pipe_fds[2]; pipe(pipe_fds); close(pipe_fds[0]); close(pipe_fds[1]); pfd.fd = pipe_fds[0]; pfd.events = POLLIN | POLLOUT | POLLPRI; pfd.revents = 0; ret = poll(&pfd, 1, -1); printf("ret: %d\n", ret); if (ret < 0) printf("error: %s", strerror(errno)); else { puts("revents: "); if (pfd.revents & POLLERR) printf(" POLLERR"); if (pfd.revents & POLLHUP) printf(" POLLHUP"); if (pfd.revents & POLLNVAL) printf(" POLLNVAL"); puts(""); } return 0; } This hangs on uClibc-ng aarch64 and Kalray's arch (kv3) but does the following on musl and glibc: " ret: 1 revents: POLLNVAL " strace output of this program with uClibc *without* the patch applied: pselect6(4, [3], [3], [3], NULL, NULL) = -1 EBADF (Bad file descriptor) pselect6(4, [3], [3], [3], {tv_sec=0, tv_nsec=0}, NULL) = -1 EBADF (Bad file descriptor) pselect6(0, 0x7ffffffb80, 0x7ffffffb68, 0x7ffffffb50, NULL, NULL (never finishes) strace output of this program with uClibc *with* the patch applied: pselect6(4, [3], [3], [3], NULL, NULL) = -1 EBADF (Bad file descriptor) pselect6(4, [3], [3], [3], {tv_sec=0, tv_nsec=0}, NULL) = -1 EBADF (Bad file descriptor) write(1, "ret: 1\n", 7ret: 1 ) = 7 write(1, "revents: \n", 10revents: ) = 10 write(1, " POLLNVAL\n", 10 POLLNVAL ) = 10 exit_group(0) = ? +++ exited with 0 +++

2019-10-30Make __syscall_error return long, as expected by syscall() callersCarlos Santos
The return type of syscall() is long so __syscall_error, which is jumped to by syscall handlers to stash an error number into errno, must return long too otherwhise it returs 4294967295L instead of -1L. For example, syscall for x86_64 is defined in libc/sysdeps/linux/x86_64/syscall.S as syscall: movq %rdi, %rax /* Syscall number -> rax. */ movq %rsi, %rdi /* shift arg1 - arg5. */ movq %rdx, %rsi movq %rcx, %rdx movq %r8, %r10 movq %r9, %r8 movq 8(%rsp),%r9 /* arg6 is on the stack. */ syscall /* Do the system call. */ cmpq $-4095, %rax /* Check %rax for error. */ jae __syscall_error /* Branch forward if it failed. */ ret /* Return to caller. */ In libc/sysdeps/linux/x86_64/__syscall_error.c, __syscall_error is defined as int __syscall_error(void) attribute_hidden; int __syscall_error(void) { register int err_no __asm__ ("%rcx"); __asm__ ("mov %rax, %rcx\n\t" "neg %rcx"); __set_errno(err_no); return -1; } So __syscall_error returns -1 as a 32-bit int in a 64-bit register, %rax (0x00000000ffffffff, whose decimal value is decimal 4294967295) and a test like this always returns false: if (syscall(number, ...) == -1) foo(); Fix the error by making __syscall_error return a long, like syscall(). The problem can be circumvented by the caller by coercing the returned value to int before comparing it to -1: if ((int) syscall(number, ...) == -1) foo(); The same problem probably occurs on other 64-bit systems but so far only x86_64 was tested, so this change must be considered experimental.
