| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates the struct termios definition on its own header and adds arch-defined ones for ABIs that deviate from generic implementation.

* termios: Define TIOCSER_TEMT with __USE_MISC (BZ#17783)Adhemerval Zanella2019-01-033-3/+10
| | | | | | | | | | | | | | | | | | This patch defines TIOCSER_TEMT on all architectures using the __USE_MISC guards similar to BZ#17782 fix. Latest Linux UAPI defines TIOCSER_TEMT with the same value for all architectures, so it is safe to use the value as default for all ABIs.

* Update Linux kernel version in tst-mman-consts.py.Joseph Myers2019-01-021-1/+1
| | | | | | | | | | | | | | | This patch updates the Linux kernel version in tst-mman-consts.py to 4.20 (meaning that's the version for which glibc is expected to have the same constants as the kernel, up to the exceptions listed in the test). (Once we have more such tests sharing common infrastructure, I expect the kernel version will be something set in the infrastructure shared by all such tests, rather than something needing updating separately for each test for each new kernel version.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Expect constants to match with Linux 4.20.
* ARM: fix kernel assisted atomics with GCC 8 (bug 24034)Aurelien Jarno2019-01-021-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pre-ARMv7 CPUs are missing atomic compare and exchange and/or barrier instructions. Therefore those are implemented using kernel assistance, calling a kernel function at a specific address, and passing the arguments in the r0 to r4 registers. This is done by specifying registers for local variables. The a_ptr variable is placed in the r2 register and declared with __typeof (mem). According to the GCC documentation on local register variables, if mem is a constant pointer, the compiler may substitute the variable with its initializer in asm statements, which may cause the corresponding operand to appear in a different register. This happens in __libc_start_main with the pointer to the thread counter for static binaries (but not the shared ones): # ifdef SHARED unsigned int *ptr = __libc_pthread_functions.ptr_nthreads; # ifdef PTR_DEMANGLE PTR_DEMANGLE (ptr); # endif # else extern unsigned int __nptl_nthreads __attribute ((weak)); unsigned int *const ptr = &__nptl_nthreads; # endif This causes static binaries using threads to crash when the GNU libc is built with GCC 8 and most notably tst-cancel21-static. To fix that, use the same trick than for the volatile qualifier, defining a_ptr as a union. Changelog: [BZ #24034] * sysdeps/unix/sysv/linux/arm/atomic-machine.h (__arm_assisted_compare_and_exchange_val_32_acq): Use uint32_t rather than __typeof (...) for the a_ptr variable.
* Add IPV6_MULTICAST_ALL from Linux 4.20 to bits/in.h.Joseph Myers2019-01-011-0/+1
| | | | | | | | | | This patch adds the IPV6_MULTICAST_ALL constant from Linux 4.20 to bits/in.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_MULTICAST_ALL): New macro.

| | | | | | | | | | This patch adds the HWCAP_SSBS constant from Linux 4.20 to the AArch64 bits/hwcap.h. Tested with build-many-glibcs.py for aarch64-linux-gnu. * sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SSBS): New macro.
* Update syscall-names.list for Linux 4.20.Joseph Myers2019-01-011-2/+3
| | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 4.20. Although there are no new syscalls, the riscv_flush_icache syscall has moved to asm/unistd.h (previously in asm/syscalls.h) and so now needs to be added to the list. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 4.20. (riscv_flush_icache): New syscall.

* riscv: Use __has_include__ to include <asm/syscalls.h> [BZ #24022]H.J. Lu2018-12-311-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <asm/syscalls.h> has been removed by commit 27f8899d6002e11a6e2d995e29b8deab5aa9cc25 Author: David Abdurachmanov <david.abdurachmanov@gmail.com> Date: Thu Nov 8 20:02:39 2018 +0100 riscv: add asm/unistd.h UAPI header Marcin Juszkiewicz reported issues while generating syscall table for riscv using 4.20-rc1. The patch refactors our unistd.h files to match some other architectures. - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h - Adjust kernel asm/unistd.h So now asm/unistd.h UAPI header should show all syscalls for riscv. <asm/syscalls.h> may be restored by Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header Date: Tue, 11 Dec 2018 09:09:35 +0100 UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header, which did resolve issue with missing syscalls macros resulting in glibc (2.28) build failure. It also broke glibc in a different way: asm/syscalls.h is being used by glibc. I noticed this while doing Fedora 30/Rawhide mass rebuild. The patch returns asm/syscalls.h header and incl. it into asm/unistd.h. I plan to send a patch to glibc to use asm/unistd.h instead of asm/syscalls.h In the meantime, we use __has_include__, which was added to GCC 5, to check if <asm/syscalls.h> exists before including it. Tested with build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7. [BZ #24022] * sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if <asm/syscalls.h> exists with __has_include__ before including it.
* Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers2018-12-212-0/+3
| | | | | | | | | | | | | | | | | | | | | | The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations. [BZ #24023] * sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf PLT reference in libc.so. * sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow _Q_lltoq and _Q_qtod PLT references in libc.so.

* Remove __ASSUME_ST_INO_64_BIT.Joseph Myers2018-12-187-43/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment "However, SH is lame, and still does not have a 64-bit inode field.". The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha case is, however, trivially useless: none of the files that test __ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel support for stat64 syscalls, with a 64-bit st_ino field, in Linux 2.6.4; the define to 0 for Alpha in glibc predates that). The SH kernel gained support for a 64-bit st_ino in struct stat64 in commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64() syscall."), which is in Linux 2.6.22 and later. So the redefinition of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of the files testing it do so immediately after a stat64-family syscall has been used, which will always have set the 64-bit st_ino correctly (in addition to the 32-bit __st_ino), while the relevant code __xstat32_conv executes only after such a syscall in the function calling __xstat32_conv. Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it. Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases around it identical, so that conditional is also removed. Tested compilation with build-many-glibcs.py for its Alpha and SH configurations; also ran the glibc testsuite for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT): Remove macro definition. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_ST_INO_64_BIT): Do not undefine and define. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_ST_INO_64_BIT): Likewise. * sysdeps/unix/sysv/linux/fxstat64.c: Do not include <kernel-features.h>.

* Do not clobber r12 for ia64 syscalls.Joseph Myers2018-12-171-1/+1
| | | | | | | | | | | | | GCC mainline now gives errors for an asm that clobbers the stack pointer. According to <https://gcc.gnu.org/ml/gcc-patches/2018-12/msg00932.html> GCC previously ignored such a clobber; thus, this patch removes it from the clobbers for ia64 syscalls.

* Add test that MAP_* constants agree with kernel.Joseph Myers2018-12-172-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the process of building up and using Python infrastructure for extracting and using values in headers, this patch adds a test that MAP_* constants from sys/mman.h agree with those in the Linux kernel headers. (Other sys/mman.h constants could be added to the test separately.) This set of constants has grown over time, so the generic code is enhanced to allow saying extra constants are OK on either side of the comparison (where the caller sets those parameters based on the Linux kernel headers version, compared with the version the headers were last updated from). Although the test is a custom Python file, my intention is to move in future to a single Python script for such tests and text files it takes as inputs, once there are enough examples to provide a guide to the common cases in such tests (I'd like to end up with most or all such sets of constants copied from kernel headers having such tests, and likewise for structure layouts from the kernel). The Makefile code is essentially the same as for tst-signal-numbers, but I didn't try to find an object file to depend on to represent the dependency on the headers used by the test (the conform/ tests don't try to represent such header dependencies at all, for example). Tested with build-many-glibcs.py, and also for x86_64 with older kernel headers. * scripts/glibcextract.py (compare_macro_consts): Take parameters to allow extra macros from first or second sources. * sysdeps/unix/sysv/linux/tst-mman-consts.py: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (tests-special): Add $(objpfx)tst-mman-consts.out.

* Move tst-signal-numbers to Python.Joseph Myers2018-12-103-90/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the tst-signal-numbers test from shell + awk to Python. As with gen-as-const, the point is not so much that shell and awk are problematic for this code, as that it's useful to build up general infrastructure in Python for use of a range of code involving extracting values from C headers. This patch moves some code from gen-as-const.py to a new glibcextract.py, which also gains functions relating to listing macros, and comparing the values of a set of macros from compiling two different pieces of code. It's not just signal numbers that should have such tests; pretty much any case where glibc copies constants from Linux kernel headers should have such tests that the values and sets of constants agree except where differences are known to be OK. Much the same also applies to structure layouts (although testing those without hardcoding lists of fields to test will be more complicated). Given this patch, another test for a set of macros would essentially be just a call to glibcextract.compare_macro_consts (plus boilerplate code - and we could move to having separate text files defining such tests, like the .sym inputs to gen-as-const, so that only a single Python script is needed for most such tests). Some such tests would of course need new features, e.g. where the set of macros changes in new kernel versions (so you need to allow new macro names on the kernel side if the kernel headers are newer than the version known to glibc, and extra macros on the glibc side if the kernel headers are older). tst-syscall-list.sh could become a Python script that uses common code to generate lists of macros but does other things with its own custom logic. There are a few differences from the existing shell + awk test. Because the new test evaluates constants using the compiler, no special handling is needed any more for one signal name being defined to another. Because asm/signal.h now needs to pass through the compiler, not just the preprocessor, stddef.h is included as well (given the asm/signal.h issue that it requires an externally provided definition of size_t). The previous code defined __ASSEMBLER__ with asm/signal.h; this is removed (__ASSEMBLY__, a different macro, eliminates the requirement for stddef.h on some but not all architectures). Tested for x86_64, and with build-many-glibcs.py. * scripts/glibcextract.py: New file. * scripts/gen-as-const.py: Do not import os.path, re, subprocess or tempfile. Import glibcexctract.

* Fix Arm __ASSUME_COPY_FILE_RANGE (bug 23915).Joseph Myers2018-11-231-3/+4
| | | | | | | | | | | | | | | | | The generic kernel-features.h defines __ASSUME_COPY_FILE_RANGE for 4.5 and later kernels. However, for 32-bit Arm binaries running on 64-bit Arm kernels, the syscall was only wired up in the 4.7 kernel, although the 32-bit Arm kernel had the syscall from 4.5 onwards. This patch corrects the Arm kernel-features.h to undefine the macro for configured minimum kernel versions before 4.7. Tested (compilation only) with a build-many-glibcs.py build for arm-linux-gnueabi.
