2024-10-01Disable _TIME_BITS if the compiler defaults to itAdhemerval Zanella1-0/+3
Even though building glibc with 64 bit time_t flags is not supported, and the usual way is to patch the build system to avoid it; some systems do enable it by default, and it increases the requirements to build glibc in such cases (it also does not help newcomers when trying to build glibc). The conform namespace and linknamespace tests also do not expect that flag to be set by default, so disable it as well. Checked with a build/check for major ABI and some (i386, arm, mipsel, hppa) with a toolchain that has LFS flags by default. Reviewed-by: DJ Delorie <dj@redhat.com>

2024-06-12tunables: sort tunables list (BZ 30027)DJ Delorie1-1/+1
Sort tunables list at the time it's generated. Note: adding new tunables will cause other tunable IDs to change, but that was the case before anyway. POSIX does not guarantee the order of "foo in bar" AWK operators, so the order was indeterminate before anyway. Even depending on the order to be the same across multiple calls, such as in this script, is undefined, so sorting the list resolves that also. Note that sorting is not dependent on the user's locale.

2024-05-09Force DT_RPATH for --enable-hardcoded-path-in-testsH.J. Lu1-3/+6
On Fedora 40/x86-64, linker enables --enable-new-dtags by default which generates DT_RUNPATH instead of DT_RPATH. Unlike DT_RPATH, DT_RUNPATH only applies to DT_NEEDED entries in the executable and doesn't applies to DT_NEEDED entries in shared libraries which are loaded via DT_NEEDED entries in the executable. Some glibc tests have libstdc++.so.6 in DT_NEEDED, which has libm.so.6 in DT_NEEDED. When DT_RUNPATH is generated, /lib64/libm.so.6 is loaded for such tests. If the newly built glibc is older than glibc 2.36, these tests fail with assert/tst-assert-c++: /export/build/gnu/tools-build/glibc-gitlab-release/build-x86_64-linux/libc.so.6: version `GLIBC_2.36' not found (required by /lib64/libm.so.6) assert/tst-assert-c++: /export/build/gnu/tools-build/glibc-gitlab-release/build-x86_64-linux/libc.so.6: version `GLIBC_ABI_DT_RELR' not found (required by /lib64/libm.so.6) Pass -Wl,--disable-new-dtags to linker when building glibc tests with --enable-hardcoded-path-in-tests.

Add --enable-fortify-source option. It is now possible to enable fortification through a configure option. The level may be given as parameter, if none is provided, the configure script will determine what is the highest level possible that can be set considering GCC built-ins availability and set it. If level is explicitly set to 3, configure checks if the compiler supports the built-in function necessary for it or raise an error if it isn't. If the configure option isn't explicitly enabled, it _FORTIFY_SOURCE is forcibly undefined (and therefore disabled). The result of the configure checks are new variables, ${fortify_source} and ${no_fortify_source} that can be used to appropriately populate CFLAGS. A dedicated patch will follow to make use of this variable in Makefiles when necessary. Updated NEWS and INSTALL. Adding dedicated x86_64 variant that enables the configuration.

The errlist.c is built with -fno-toplevel-reorder to avoid compiler to reorder the compat assembly directives due an assembler issue [1] (fixed on 2.39). This patch removes the compiler flags by split the compat symbol generation in two phases. First the _sys_errlist_internal internal without any compat symbol directive is preprocessed to generate an assembly source code. This generate assembly is then used as input on a platform agnostic errlist-data.S which then creates the compat definitions. This prevents compiler to move any compat directive prior the _sys_errlist_internal definition itself. Checked on a make check run-built-tests=no on all affected ABIs.

2021-12-13Replace --enable-static-pie with --disable-default-pieSiddhesh Poyarekar1-7/+14
Build glibc programs and tests as PIE by default and enable static-pie automatically if the architecture and toolchain supports it. Also add a new configuration option --disable-default-pie to prevent building programs as PIE. Only the following architectures now have PIE disabled by default because they do not work at the moment. hppa, ia64, alpha and csky don't work because the linker is unable to handle a pcrel relocation generated from PIE objects. The microblaze compiler is currently failing with an ICE. GNU hurd tries to enable static-pie, which does not work and hence fails. All these targets have default PIE disabled at the moment and I have left it to the target maintainers to enable PIE on their targets. build-many-glibcs runs clean for all targets. I also tested x86_64 on Fedora and Ubuntu, to verify that the default build as well as --disable-default-pie work as expected with both system toolchains.

2021-09-17Run conform/ tests using newly built libcJoseph Myers1-7/+16
Although the conform/ header tests are built using the headers of the glibc under test, the execution tests from conformtest (a few tests of the values of macros evaluating to string constants) are linked and run with system libc, not the newly built libc. Apart from preventing testing in cross environments, this can be a problem even for native testing. Specifically, it can be useful to do native testing when building with a cross compiler that links with a libc that is not the system libc; for example, on x86_64, you can test all three ABIs that way if the kernel support is present, even if the host OS lacks 32-bit or x32 libraries or they are older than the libraries in the sysroot used by the compiler used to build glibc. This works for almost all tests, but not for these conformtest tests. Arrange for conformtest to link and run test programs similarly to other tests, with consequent refactoring of various variables in Makeconfig to allow passing relevant parts of the link-time command lines down to conformtest. In general, the parts of the link command involving $@ or $^ are separated out from the parts that should be passed to conformtest (the variables passed to conformtest still involve various variables whose names involve $(@F), but those variables simply won't be defined for the conformtest makefile rules and I think their presence there is harmless). This is also most of the support that would be needed to allow running those tests of string constants for cross testing when test-wrapper is defined. That will also need changes to where conformtest.py puts the test executables, so it puts them in the main object directory (expected to be shared with a test system in cross testing) rather than /tmp (not expected to be shared) as at present. Tested for x86_64.

This results in an error during build which is not noticed because it somehow does not terminate the build. Exclude the modules cppflags from the pre-processing command and fix up the time64-compat.mk target so that the build runs without issues. Reviewed-by: Andreas Schwab <schwab@linux-m68k.org>
2021-06-15y2038: Add test coverageAdhemerval Zanella1-0/+14
It is enabled through a new rule, tests-y2038, which is built only when the ABI supports the comapt 64-bit time_t (defined by the header time64-compat.h, which also enables the creation of the symbol Version for Linux). It means the tests are not built for ABI which already provide default 64-bit time_t. The new rule already adds the required LFS and 64-bit time_t compiler flags. The current coverage is: * libc: - adjtime tst-adjtime-time64 - adjtimex tst-adjtimex-time64 - clock_adjtime tst-clock_adjtime-time64 - clock_getres tst-clock-time64, tst-cpuclock1-time64 - clock_gettime tst-clock-time64, tst-clock2-time64, tst-cpuclock1-time64 - clock_nanosleep tst-clock_nanosleep-time64, tst-cpuclock1-time64 - clock_settime tst-clock2-time64 - cnd_timedwait tst-cnd-timedwait-time64 - ctime tst-ctime-time64 - ctime_r tst-ctime-time64 - difftime tst-difftime-time64 - fstat tst-stat-time64 - fstatat tst-stat-time64 - futimens tst-futimens-time64 - futimes tst-futimes-time64 - futimesat tst-futimesat-time64 - fts_* tst-fts-time64 - getitimer tst-itimer-timer64 - getrusage - gettimeofday tst-clock_nanosleep-time64 - glob / globfree tst-gnuglob64-time64 - gmtime tst-gmtime-time64 - gmtime_r tst-gmtime-time64 - lstat tst-stat-time64 - localtime tst-y2039-time64 - localtime_t tst-y2039-time64 - lutimes tst-lutimes-time64 - mktime tst-mktime4-time64 - mq_timedreceive tst-mqueue{1248}-time64 - mq_timedsend tst-mqueue{1248}-time64 - msgctl test-sysvmsg-time64 - mtx_timedlock tst-mtx-timedlock-time64 - nanosleep tst-cpuclock{12}-time64, tst-mqueue8-time64, tst-clock-time64 - nftw / ftw ftwtest-time64 - ntp_adjtime tst-ntp_adjtime-time64 - ntp_gettime tst-ntp_gettime-time64 - ntp_gettimex tst-ntp_gettimex-time64 - ppoll tst-ppoll-time64 - pselect tst-pselect-time64 - pthread_clockjoin_np tst-join14-time64 - pthread_cond_clockwait tst-cond11-time64 - pthread_cond_timedwait tst-abstime-time64 - pthread_mutex_clocklock tst-abstime-time64 - pthread_mutex_timedlock tst-abstime-time64 - pthread_rwlock_clockrdlock tst-abstime-time64, tst-rwlock14-time64 - pthread_rwlock_clockwrlock tst-abstime-time64, tst-rwlock14-time64 - pthread_rwlock_timedrdlock tst-abstime-time64, tst-rwlock14-time64 - pthread_rwlock_timedwrlock tst-abstime-time64, tst-rwlock14-time64 - pthread_timedjoin_np tst-join14-time64 - recvmmsg tst-cancel4_2-time64 - sched_rr_get_interval tst-sched_rr_get_interval-time64 - select tst-select-time64 - sem_clockwait tst-sem5-time64 - sem_timedwait tst-sem5-time64 - semctl test-sysvsem-time64 - semtimedop test-sysvsem-time64 - setitimer tst-mqueue2-time64, tst-itimer-timer64 - settimeofday tst-settimeofday-time64 - shmctl test-sysvshm-time64 - sigtimedwait tst-sigtimedwait-time64 - stat tst-stat-time64 - thrd_sleep tst-thrd-sleep-time64 - time tst-mqueue{1248}-time64 - timegm tst-timegm-time64 - timer_gettime tst-timer4-time64 - timer_settime tst-timer4-time64 - timerfd_gettime tst-timerfd-time64 - timerfd_settime tst-timerfd-time64 - timespec_get tst-timespec_get-time64 - timespec_getres tst-timespec_getres-time64 - utime tst-utime-time64 - utimensat tst-utimensat-time64 - utimes tst-utimes-time64 - wait3 tst-wait3-time64 - wait4 tst-wait4-time64 * librt: - aio_suspend tst-aio6-time64 - mq_timedreceive tst-mqueue{1248}-time64 - mq_timedsend tst-mqueue{1248}-time64 - timer_gettime tst-timer4-time64 - timer_settime tst-timer4-time64 * libanl: - gai_suspend Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
2021-06-03dlfcn: Cleanups after -ldl is no longer requiredFlorian Weimer1-6/+0
This commit removes the ELF constructor and internal variables from dlfcn/dlfcn.c. The file now serves the same purpose as nptl/libpthread-compat.c, so it is renamed to dlfcn/libdl-compat.c. The use of libdl-shared-only-routines ensures that libdl.a is empty. This commit adjusts the test suite not to use $(libdl). The libdl.so symbolic link is no longer installed.

2021-03-15Build libc-start with stack protector for SHAREDSiddhesh Poyarekar1-0/+8
This does not change the emitted code since __libc_start_main does not return, but is important for formal flags compliance. This also cleans up the cosmetic inconsistency in the stack protector flags in csu, especially the incorrect value of STACK_PROTECTOR_LEVEL.

2021-01-02Update copyright dates with scripts/update-copyrightsPaul Eggert1-1/+1
I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master
2020-11-16Add {,sysdep-}ld-library-path make variableSamuel Thibault1-0/+3
On GNU/Hurd we not only need $(common-objpfx) in LD_LIBRARY_PATH when loading dynamic objects, but also $(common-objpfx)/mach and $(common-objpfx)/hurd. This adds an ld-library-path variable to be used as LD_LIBRARY_PATH basis in Makefiles, and a sysdep-ld-library-path variable for sysdeps to add some more paths, here mach/ and hurd/.
2020-04-29Makeconfig: Use $(error ...) to output error messageSimon Marchi1-1/+1
Being not familiar with the glibc repository, I typed "make" inside some subdirectory that has a Makefile, and was met with: $ make ../Makeconfig:42: *** missing separator. Stop. At Makeconfig:42, we have: objdir must be defined by the build-directory Makefile. Change that to use $(error ...), which I guess was the original intention. The result is: $ make ../Makeconfig:42: *** objdir must be defined by the build-directory Makefile. Stop.
2020-03-25Makeconfig: sandwich gnulib-tests between libc/ld linking of testsPaul E. Murphy1-6/+6
This better resembles the default linking process with the gnulibs, and also resolves the increasingly difficult to maintain f128-loader-link usage on powerpc64le as some libgcc symbols are dependent on those found in the loader (ld).
