* Add NEWS entry for Update to Unicode 13.0.0 [BZ #25819]Mike FABIAN2020-07-101-2/+2
| | | | | | | | | Unicode 13.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 13.0.0, using the generator scripts contributed by Mike FABIAN (Red Hat).

* Remove --enable-obsolete-nsl configure flagPetr Vorel2020-07-081-5/+15
| | | | | | | | | | | | | | | | | | | this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.

* nss: Remove cryptographic key support from nss_files, nss_nis, nss_nisplusFlorian Weimer2020-07-071-0/+6

* string: Add strerrorname_np and strerrordesc_npAdhemerval Zanella2020-07-071-0/+10
| | | | | | | | | | | | | | | | | The strerrorname_np returns error number name (e.g. "EINVAL" for EINVAL) while strerrordesc_np returns string describing error number (e.g "Invalid argument" for EINVAL). Different than strerror, strerrordesc_np does not attempt to translate the return description, both functions return NULL for an invalid error number. They should be used instead of sys_errlist and sys_nerr, both are thread and async-signal safe. These functions are GNU extensions.

* Add the __libc_single_threaded variableFlorian Weimer2020-07-061-0/+6
| | | | | | | | | | | | | | The variable is placed in libc.so, and it can be true only in an outer libc, not libcs loaded via dlmopen or static dlopen. Since thread creation from inner namespaces does not work, pthread_create can update __libc_single_threaded directly. Using __libc_early_init and its initial flag, implementation of this variable is very straightforward. A future version may reset the flag during fork (but not in an inner namespace), or after joining all threads except one. Reviewed-by: DJ Delorie <dj@redhat.com>
* Linux: Perform rseq registration at C startup and thread creationMathieu Desnoyers2020-07-061-0/+10
| | | | | | | | | | | | | | | | | | | Register rseq TLS for each thread (including main), and unregister for each thread (excluding main). "rseq" stands for Restartable Sequences. See the rseq(2) man page proposed here: https://lkml.org/lkml/2018/9/19/647 Those are based on glibc master branch commit 3ee1e0ec5c. The rseq system call was merged into Linux 4.18. The TLS_STATIC_SURPLUS define is increased to leave additional room for dlopen'd initial-exec TLS, which keeps elf/tst-auditmany working. The increase (76 bytes) is larger than 32 bytes because it has not been increased in quite a while. The cost in terms of additional TLS storage is quite significant, but it will also obscure some initial-exec-related dlopen failures.

| | | | | | | | | | | | | | On platforms where long double may have two different formats, i.e.: the same format as double (64-bits) or something else (128-bits), building with -mlong-double-128 is the default and function calls in the user program match the name of the function in Glibc. When building with -mlong-double-64, Glibc installed headers redirect such calls to the appropriate function. Likewise, the internals of glibc are now built against IEEE long double. However, the only (minimally) notable usage of long double is difftime. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add compiler feature tests to ensure we can build ieee128 long double. These test for -mabi=ieeelongdouble, -mno-gnu-attribute, and -Wno-psabi. Likewise, verify some compiler bugs have been addressed. These aren't helpful for building glibc, but may cause test failures when testing the new long double. See notes below from Raji. On powerpc64le, some older compiler versions give error for the function signbit() for 128-bit floating point types. This is fixed by PR83862 in gcc 8.0 and backported to gcc6 and gcc7. This patch adds a test to check compiler version to avoid compiler errors during make check. Likewise, test for -mno-gnu-attribute support which was On powerpc64le, a few files are built on IEEE long double mode (-mabi=ieeelongdouble), whereas most are built on IBM long double mode (-mabi=ibmlongdouble, the default for -mlong-double-128). Since binutils 2.31, linking object files with different long double modes causes errors similar to: ld: libc_pic.a(s_isinfl.os) uses IBM long double, libc_pic.a(ieee128-qefgcvt.os) uses IEEE long double. collect2: error: ld returned 1 exit status make[2]: *** [../Makerules:649: libc_pic.os] Error 1 The warnings are fair and correct, but in order for glibc to have support for both long double modes on powerpc64le, they have to be ignored. This can be accomplished with the use of -mno-gnu-attribute option when building the few files that require IEEE long double mode. However, -mno-gnu-attribute is not available in GCC 6, the minimum version required to build glibc, so this patch adds a test for this feature in powerpc64le builds, and fails early if it's not available.

* Linux: Use system call tables during buildFlorian Weimer2020-01-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Use <arch-syscall.h> instead of <asm/unistd.h> to obtain the system call numbers. A few direct includes of <asm/unistd.h> need to be removed (if the system call numbers are already provided indirectly by <sysdep.h>) or replaced with <sys/syscall.h>. Current Linux headers for alpha define the required system call names, so most of the _NR_* hacks are no longer needed. For the 32-bit arm architecture, eliminate the INTERNAL_SYSCALL_ARM macro, now that we have regular system call names for cacheflush and set_tls. There are more such cleanup opportunities for other architectures, but these cleanups are required to avoid macro redefinition errors during the build. For ia64, it is desirable to use <asm/break.h> directly to obtain the break number for system calls (which is not a system call number itself). This requires replacing __BREAK_SYSCALL with __IA64_BREAK_SYSCALL because the former is defined as an alias in <asm/unistd.h>, but not in <asm/break.h>.

* Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304]Florian Weimer2019-11-271-0/+6
| | | | | | | | | | | | | | | | | | | | | If a lazy binding failure happens during the execution of an ELF constructor or destructor, the dynamic loader catches the error and reports it using the dlerror mechanism. This is undesirable because there could be other constructors and destructors that need processing (which are skipped), and the process is in an inconsistent state at this point. Therefore, we have to issue a fatal dynamic loader error error and terminate the process. Note that the _dl_catch_exception in _dl_open is just an inner catch, to roll back some state locally. If called from dlopen, there is still an outer catch, which is why calling _dl_init via call_dl_init and a no-exception is required and cannot be avoiding by moving the _dl_init call directly into _dl_open. _dl_fini does not need changes because it does not install an error handler, so errors are already fatal there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consolidate generic gettimeofday implementation to use clock_gettime. Linux ports that still provide gettimeofday through vDSO are not changed. Remove sysdeps/unix/clock_gettime.c, which implemented clock_gettime using gettimeofday; new OS ports must provide a real implementation of clock_gettime. Rename sysdeps/mach/gettimeofday.c to sysdeps/mach/clock_gettime.c and convert into an implementation of clock_gettime. It only supports CLOCK_REALTIME; Mach does not appear to have any support for monotonic clocks. It uses __host_get_time, which provides at best microsecond resolution. Hurd is currently using sysdeps/posix/clock_getres.c for clock_getres; its output for CLOCK_REALTIME is based on sysconf (_SC_CLK_TCK), and I do not know whether that gives the correct result. Unlike settimeofday, there are no known uses of gettimeofday's vestigial "get time zone" feature that are not bugs. (The per-process timezone support in localtime and friends is unrelated, and the programs that set the kernel's offset between the hardware clock and UTC do not need to read it back.) Therefore, this feature is dummied out. Henceforth, if gettimeofday's "struct timezone" argument is not NULL, it will write zeroes to both fields. Any program that is actually looking at this data will thus think it is running in UTC, which is probably more correct than whatever it was doing before. [__]gettimeofday no longer has any internal callers, so we can now remove its internal prototype and PLT bypass aliases. The __gettimeofday@GLIBC_2.0 export remains, in case it is used by any third-party code. It also allows to simplify the arch-specific implementation on x86 and powerpc to remove the hack to disable the internal route to non iFUNC variant for internal symbol. This patch also fixes a missing optimization on aarch64, powerpc, and x86 where the code used on static build do not use the vDSO.

* Consolidate and deprecate ftimeZack Weinberg2019-10-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | ftime is an obsolete variation on gettimeofday, offering only millisecond time resolution; it was probably a system call in ooold versions of BSD Unix. For historic reasons, we had three implementations of it. These are all consolidated into time/ftime.c, and then the function is deprecated. For some reason, the implementation of ftime in terms of gettimeofday was rounding rather than truncating microseconds to milliseconds. In all the other places where we use a higher-resolution time function to implement a lower-resolution one, we truncate. ftime is changed to match, just for tidiness' sake. Like gettimeofday, ftime tries to report the time zone, and using that information is always a bug. This patch dummies out the reported timezone information; the timezone and dstflag fields of the returned "struct timeb" will always be zero.

The vestigial "set time zone" feature of settimeofday complicates the generic settimeofday implementation a little. The only remaining uses of this feature that aren't just bugs, are using it to inform the Linux kernel of the offset between the hardware clock and UTC, on systems where the hardware clock doesn't run in UTC (usually because of dual-booting with Windows). There currently isn't any other way to do this. However, the callers that do this call settimeofday with _only_ the timezone argument non-NULL. Therefore, glibc's new behavior is: callers of settimeofday must supply one and only one of the two arguments. If both arguments are non-NULL, or both arguments are NULL, the call fails and sets errno to EINVAL. When only the timeval argument is supplied, settimeofday calls __clock_settime(CLOCK_REALTIME), same as stime. When only the timezone argument is supplied, settimeofday calls a new internal function called __settimezone. On Linux, only, this function will pass the timezone structure to the settimeofday system call. On all other operating systems, and on Linux architectures that don't define __NR_settimeofday, __settimezone is a stub that always sets errno to ENOSYS and returns -1. The settimeoday syscall is enabled on Linux by the flag COMPAT_32BIT_TIME, which is an option to either 32-bits ABIs or COMPAT builds (defined usually by 64-bit kernels that want to support 32-bit ABIs, such as x86). The idea to future 64-bit time_t only ABIs is to not provide settimeofday syscall. The same semantics are implemented for Linux/Alpha's GLIBC_2.0 compat symbol for settimeofday. There are no longer any internal callers of __settimeofday, so the internal prototype is removed. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

* Add tgmath.h macros for narrowing functions.Joseph Myers2019-08-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When adding some of the TS 18661 narrowing functions for glibc 2.28, I deferred adding corresponding <tgmath.h> support because of unresolved questions about the specification for those type-generic macros, especially in relation to _FloatN and _FloatNx types. Those issues are now clarified in the response to Clarification Request 13 to TS 18661-3, and this patch adds the deferred tgmath.h support. As with other tgmath.h macros, there are fairly straightforward implementations based on __builtin_tgmath for GCC 8 and later, which result in exactly the right function being called in each case, and more complicated implementations for GCC 7 and earlier, which generally result in a function being called whose arguments have the right format (i.e. an alias for the right function), but which might not be exactly the function name specified by TS 18661. In one case with older compilers (f32x* macros, where the type _Float64x exists and all the arguments have type _Float32 or _Float32x), there is a further relaxation and the function called may have arguments narrower than the one specified by the TS, but still wide enough to represent the arguments exactly, so the result of the call is unchanged (as this does not affect any case where rounding of integer arguments might be involved). With GCC 6 or before this is inherently unavoidable (but still harmless and not detectable by how the compiled program behaves, unless it redefines the functions in question like the testcases do) because _Float32x and _Float64 are both typedefs for double in that case but the specified semantics result in different functions, with different argument formats, being called for those two argument types. Tests for the new macros are handled through gen-tgmath-tests.py, which deals with the special-case handling for older GCC. Tested as follows: with the full glibc testsuite on x86_64 and x86 (with GCC 6, 7 and 8); with the math/ tests on aarch64 and arm (with GCC 6, 7 and 8); with build-many-glibcs.py (with GCC 6, 7 and 9). * math/tgmath.h [__HAVE_FLOAT128X]: Give error.

* Make totalorder and totalordermag functions take pointer arguments.Joseph Myers2019-08-151-1/+6

This patch updates glibc accordingly. As a defect resolution, the API is changed unconditionally rather than supporting any sort of TS 18661-1 mode for compilation with the old version of the API. There are compat symbols for existing binaries that pass floating-point arguments directly. As a consequence of changing to pointer arguments, there are no longer type-generic macros in tgmath.h for these functions. Because of the fairly complicated logic for creating libm function aliases and determining the set of aliases to create in a given glibc configuration, rather than duplicating all that in individual source files to create the versioned and compat symbols, the source files for the various versions of totalorder functions are set up to redefine weak_alias before using libm_alias_* macros to create the symbols required. In turn, this requires creating a separate alias for each symbol version pointing to the same implementation (see binutils bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is done automatically using __COUNTER__. (As I noted in <https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might well make sense for glibc's symbol versioning macros to do that alias creation with __COUNTER__ themselves, which would somewhat simplify the logic in the totalorder source files.) It is of course desirable to test the compat symbols. I did this with the generic libm-test machinery, but didn't wish to duplicate the actual tables of test inputs and outputs, and thought it risky to attempt to have a single object file refer to both default and compat versions of the same function in order to test them together. Thus, I created libm-test-compat_totalorder.inc and libm-test-compat_totalordermag.inc which include the generated .c files (with the processed version of those tables of inputs) from the non-compat tests, and added appropriate dependencies. I think this provides sufficient test coverage for the compat symbols without also needing to make the special ldbl-96 and ldbl-128ibm tests (of peculiarities relating to the representations of those formats that can't be covered in the generic tests) run for the compat symbols. Tests of compat symbols need to be internal tests, meaning _ISOMAC is not defined. Making some libm-test tests into internal tests showed up two other issues. GCC diagnoses duplicate macro definitions of __STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added an appropriate conditional and filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue. On ia64, include/setjmp.h ends up getting included indirectly from libm-symbols.h, resulting in conflicting definitions of the STR macro (also defined in libm-test-driver.c); I renamed the macros in include/setjmp.h. (It's arguable that we should have common internal headers used everywhere for stringizing and concatenation macros.)
