* semaphore: consolidate arch headers into a generic oneVineet Gupta2020-05-0613-422/+2
| | | | | | | | | | | | | | | | | | This consolidates the copy-pasted arch specific semaphore header into single version (based on s390) which suffices 32-bit and and 64-bit arch/ABI based on the canonical WORDSIZE. For now I've left out arches which use alternate defines to choose for 32 vs 64-bit builds (aarch64, mips) which in theory can also use the same header.

* y2038: Introduce struct __timex64 - new internal glibc typeLukasz Majewski2020-05-051-0/+46
| | | | | | | | | | | | | | | | | | | The introduced glibc's 'internal' struct __timex64 is a copy of Linux kernel's struct __kernel_timex (v5.6) introduced for properly handling data for clock_adjtime64 syscall. As the struct's __kernel_timex size is the same as for archs with __WORDSIZE == 64, proper padding and data types conversion (i.e. long to long long) had to be added for architectures with __WORDSIZE == 32 && __TIMESIZE != 64. Moreover, it stores time in struct __timeval64 rather than struct timeval, which makes it Y2038-proof.

| | | | | | | The nscd/nscd_helper.c uses __clock_gettime to get current time and on this basis calculate the relative timeout for poll. By using __clock_gettime64 on systems with __WORDSIZE == 32 && __TIMESIZE != 64 the timeout is correctly calculated after time_t overflow.

| | | | | | | | | | | | | | | This change brings 64 bit time support to inet deadline related code for architectures with __WORDSIZE == 32 && __TIMESIZE != 64. It is also safe to replace struct timespec with struct __timespec64 in deadline related structures as: - The __deadline_to_ms () returns the number of miliseconds to deadline to be used with __poll (and hence it is a relative value). - To calculate the deadline from timeval (which will be converted latter) the uintmax_t type is used (unsinged long long int).

| | | | | | | | | | | For Linux glibc ports the __TIMESIZE == 64 ensures proper aliasing for __clock_gettime64 (to __clock_gettime). When __TIMESIZE != 64 (like ARM32, PPC) the glibc expects separate definition of the __clock_gettime64. The HURD port only provides __clock_gettime, so this patch adds __clock_gettime64 as a tiny wrapper on it. Acked-by: Samuel Thibault <samuel.thibault@ens-lyon.org>

* powerpc64le/power9: guard power9 strcmp against rtld usage [BZ# 25905]Paul E. Murphy2020-05-041-0/+2
| | | | | | | | | | | | | | | | strcmp is used while resolving PLT references. Vector registers should not be used during this. The P9 strcmp makes heavy use of vector registers, so it should be avoided in rtld. This prevents quiet vector register corruption when glibc is configured with --disable-multi-arch and --with-cpu=power9. This can be seen with test-float64x-compat_totalordermag during the first call into totalordermagf64x@GLIBC_2.27. Add a guard to fallback to the power8 implementation when building power9 strcmp for libraries other than libc. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

All localedef tests which run with default paths need to have the $(complocaledir) created in testroot.pristine. The localedef binary will not by itself create the default path, but it will write into the path. By adding this we can simplify the localedef tests. The variable $complocaledir is the value of the configured $(complocaledir) which is the location of the compiled locales that will be searched by the runtime by default. The command mkdirp will be available in script setup and will be equivalent to running `mkdir -p`. The variable and command can be used to write more complex tests.

* powerpc64le: Enable support for IEEE long doubleGabriel F. T. Gomes2020-04-307-0/+232
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | X32 has 32-bit long and pointer with 64-bit off_t. Since x32 psABI requires that pointers passed in registers must be zero-extended to 64bit, x32 can share many syscall interfaces with LP64. When a LP64 syscall with long and unsigned long int arguments is used for x32, these arguments must be properly extended to 64-bit. Otherwise if the upper 32 bits of the register have undefined value, such a syscall will be rejected by kernel. For syscalls implemented in assembly codes, 'U' is added to syscall signature key letters for unsigned long, which is zero-extended to 64-bit types. SYSCALL_ULONG_ARG_1 and SYSCALL_ULONG_ARG_2 are passed to syscall-template.S for the first and the second unsigned long int arguments if PSEUDOS_HAVE_ULONG_INDICES is defined. They are used by x32 to zero-extend 32-bit arguments to 64 bits. Tested on i386, x86-64 and x32 as well as with build-many-glibcs.py.

The macros were used only in defining the union, which was used nowhere in glibc. As GMP's gmp-impl.h is over 5000 lines, the file in glibc is so far from the GMP version that it doesn't seem to make sense to keep things there that are not relevant in glibc. (I expect there is plenty more in the header after this patch that is also not relevant in glibc and can be cleaned up later.) Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch.
