* Linux: Add ppoll fortify symbol for 64 bit time_t (BZ# 29746)Adhemerval Zanella2022-11-0825-15/+125
| | | | | | | | | | | | | | | | | | | | Similar to ppoll, the poll.h header needs to redirect the poll call to a proper fortified ppoll with 64 bit time_t support. The implementation is straightforward, just need to add a similar check as __poll_chk and call the 64 bit time_t ppoll version. The debug fortify tests are also extended to cover 64 bit time_t for affected ABIs. Unfortunately it requires an aditional symbol, which makes backport tricky. One possibility is to add a static inline version if compiler supports is and call abort instead of __chk_fail, so fortified version will call __poll64 in the end. Another possibility is to just remove the fortify support for _TIME_BITS=64. Checked on i686-linux-gnu.

* elf: Rework exception handling in the dynamic loader [BZ #25486]Florian Weimer2022-11-0334-271/+89
| | | | | | | | | | | | | | | | | | | | | | | The old exception handling implementation used function interposition to replace the dynamic loader implementation (no TLS support) with the libc implementation (TLS support). This results in problems if the link order between the dynamic loader and libc is reversed (bug 25486). The new implementation moves the entire implementation of the exception handling functions back into the dynamic loader, using THREAD_GETMEM and THREAD_SETMEM for thread-local data support. These depends on Hurd support for these macros, added in commit b65a82e4e757c1e6cb7073916 ("hurd: Add THREAD_GET/SETMEM/_NC"). One small obstacle is that the exception handling facilities are used before the TCB has been set up, so a check is needed if the TCB is available. If not, a regular global variable is used to store the exception handling information. Also rename dl-error.c to dl-catch.c, to avoid confusion with the dlerror function.

* Fix build with GCC 13 _FloatN, _FloatNx built-in functionsJoseph Myers2022-10-318-12/+753
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 13 has added more _FloatN and _FloatNx versions of existing <math.h> and <complex.h> built-in functions, for use in libstdc++-v3. This breaks the glibc build because of how those functions are defined as aliases to functions with the same ABI but different types. Add appropriate -fno-builtin-* options for compiling relevant files, as already done for the case of long double functions aliasing double ones and based on the list of files used there. I fixed some mistakes in that list of double files that I noticed while implementing this fix, but there may well be more such (harmless) cases, in this list or the new one (files that don't actually exist or don't define the named functions as aliases so don't need the options). I did try to exclude cases where glibc doesn't define certain functions for _FloatN or _FloatNx types at all from the new uses of -fno-builtin-* options. As with the options for double files (see the commit message for commit 49348beafe9ba150c9bd48595b3f372299bddbb0, "Fix build with GCC 10 when long double = double."), it's deliberate that the options are used even if GCC currently doesn't have a built-in version of a given functions, so providing some level of future-proofing against more such built-in functions being added in future. Tested with build-many-glibcs.py for aarch64-linux-gnu powerpc-linux-gnu powerpc64le-linux-gnu x86_64-linux-gnu (compilers and glibcs builds) with GCC mainline.

* Correctly determine libc.so 'OUTPUT_FORMAT' when cross-compiling.Ludovic Courtès2022-10-283-5/+94
| | | | | | | | | | | | | | | | | | Commit 87d583c6e8cd0e49f64da76636ebeec033298b4d replaces the sed script with an "objdump -f" invocation to determine the 'OUTPUT_FORMAT' bit of the libc.so linker script. However, when cross-compiling, for example from x86_64-linux-gnu to aarch64-linux-gnu, "objdump -f" would report the wrong format ("elf64-little"). Conversely, "aarch64-linux-gnu-objdump -f" reports "elf64-littleaarch64" as expected. This patch changes 'configure.ac' to use AC_CHECK_TOOL rather than '$CC -print-prog-name=objdump' to determine the value of the OBJDUMP variable. That way, OBJDUMP is set to TRIPLET-objdump when cross-compiling for TRIPLET. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>

* stdlib/strfrom: Add copysign to fix NAN issue on riscv (BZ #29501)Letu Ren2022-10-283-1/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the specification of ISO/IEC TS 18661-1:2014, The strfromd, strfromf, and strfroml functions are equivalent to snprintf(s, n, format, fp) (7.21.6.5), except the format string contains only the character %, an optional precision that does not contain an asterisk *, and one of the conversion specifiers a, A, e, E, f, F, g, or G, which applies to the type (double, float, or long double) indicated by the function suffix (rather than by a length modifier). Use of these functions with any other 20 format string results in undefined behavior. strfromf will convert the arguement with type float to double first. According to the latest version of IEEE754 which is published in 2019, Conversion of a quiet NaN from a narrower format to a wider format in the same radix, and then back to the same narrower format, should not change the quiet NaN payload in any way except to make it canonical. When either an input or result is a NaN, this standard does not interpret the sign of a NaN. However, operations on bit strings—copy, negate, abs, copySign—specify the sign bit of a NaN result, sometimes based upon the sign bit of a NaN operand. The logical predicates totalOrder and isSignMinus are also affected by the sign bit of a NaN operand. For all other operations, this standard does not specify the sign bit of a NaN result, even when there is only one input NaN, or when the NaN is produced from an invalid operation. converting NAN or -NAN with type float to double doesn't need to keep the signbit. As a result, this test case isn't mandatory. The problem is that according to RISC-V ISA manual in chapter 11.3 of riscv-isa-20191213, Except when otherwise stated, if the result of a floating-point operation is NaN, it is the canonical NaN. The canonical NaN has a positive sign and all significand bits clear except the MSB, a.k.a. the quiet bit. For single-precision floating-point, this corresponds to the pattern 0x7fc00000. which means that conversion -NAN from float to double won't keep the signbit. Since glibc ought to be consistent here between types and architectures, this patch adds copysign to fix this problem if the string is NAN. This patch adds two different functions under sysdeps directory to work around the issue. This patch has been tested on x86_64 and riscv64.

* aarch64: Use memcpy_simd as the default memcpyWilco Dijkstra2022-10-266-370/+81
| | | | | | Since __memcpy_simd is the fastest memcpy on almost all cores, replace the generic memcpy with it. If SVE is available, a SVE memcpy will be used by default (including for Neoverse N2).
* aarch64: Cleanup memset ifuncWilco Dijkstra2022-10-262-17/+26
| | | | | Cleanup memset ifunc selectors. The A64FX memset relies on a ZVA size of 256, so add an explicit check.
