* elf: Add _dl_find_object functionFlorian Weimer2021-12-2832-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | It can be used to speed up the libgcc unwinder, and the internal _dl_find_dso_for_object function (which is used for caller identification in dlopen and related functions, and in dladdr). _dl_find_object is in the internal namespace due to bug 28503. If libgcc switches to _dl_find_object, this namespace issue will be fixed. It is located in libc for two reasons: it is necessary to forward the call to the static libc after static dlopen, and there is a link ordering issue with -static-libgcc and libgcc_eh.a because libc.so is not a linker script that includes ld.so in the glibc build tree (so that GCC's internal -lc after libgcc_eh.a does not pick up ld.so). It is necessary to do the i386 customization in the sysdeps/x86/bits/dl_find_object.h header shared with x86-64 because otherwise, multilib installations are broken. The implementation uses software transactional memory, as suggested by Torvald Riegel. Two copies of the supporting data structures are used, also achieving full async-signal-safety.

* microblaze: Add missing implementation when !__ASSUME_TIME64_SYSCALLSThomas Petazzoni2021-12-281-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit a92f4e6299fe0e3cb6f77e79de00817aece501ce ("linux: Add time64 pselect support"), a Microblaze specific implementation of __pselect32() was added to cover the case of kernels < 3.15 which lack the pselect6 system call. This new file sysdeps/unix/sysv/linux/microblaze/pselect32.c takes precedence over the default implementation sysdeps/unix/sysv/linux/pselect32.c. However sysdeps/unix/sysv/linux/pselect32.c provides an implementation of __pselect32() which is needed when __ASSUME_TIME64_SYSCALLS is not defined. On Microblaze, which is a 32-bit architecture, __ASSUME_TIME64_SYSCALLS is only true for kernels >= 5.1. Due to sysdeps/unix/sysv/linux/microblaze/pselect32.c taking precedence over sysdeps/unix/sysv/linux/pselect32.c, it means that when we are with a kernel >= 3.15 but < 5.1, we need a __pselect32() implementation, but sysdeps/unix/sysv/linux/microblaze/pselect32.c doesn't provide it, and sysdeps/unix/sysv/linux/pselect32.c which would provide it is not compiled in. This causes the following build failure on Microblaze with for example Linux kernel headers 4.9: [...]/build/libc_pic.os: in function `__pselect64': (.text+0x120b44): undefined reference to `__pselect32' collect2: error: ld returned 1 exit status Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | | | | | | | When the clock_id is CLOCK_PROCESS_CPUTIME_ID or CLOCK_THREAD_CPUTIME_ID, on the 5.10 kernel powerpc 32-bit, the 32-bit vDSO is executed successfully ( because the __kernel_clock_gettime in arch/powerpc/kernel/vdso32/gettimeofday.S does not support these two IDs, the 32-bit time_t syscall will be used), but tp32.tv_sec is equal to 0, causing the 64-bit time_t syscall to continue to be used, resulting in two system calls.

* powerpc64[le]: Allocate extra stack frame on syscall.SMatheus Castanho2021-12-171-0/+4
| | | | | | | | | | | | | The syscall function does not allocate the extra stack frame for scv like other assembly syscalls using DO_CALL_SCV. So after commit d120fb9941 changed the offset that is used to save LR, syscall ended up using an invalid offset, causing regressions on powerpc64. So make sure the extra stack frame is allocated in syscall.S as well to make it consistent with other uses of DO_CALL_SCV and avoid similar issues in the future.

* arm: Guard ucontext _rtld_global_ro access by SHARED, not PIC macroFlorian Weimer2021-12-172-4/+4
| | | | | | | | | | | | | | | | Due to PIE-by-default, PIC is now defined in more cases. libc.a does not have _rtld_global_ro, and statically linking setcontext fails. SHARED is the right condition to use, so that libc.a references _dl_hwcap instead of _rtld_global_ro. For static PIE support, the !SHARED case would still have to be made PIC. This patch does not achieve that. Fixes commit 23645707f12f2dd9d80b51effb2d9618a7b65565 ("Replace --enable-static-pie with --disable-default-pie").

* malloc: Add Huge Page support for mmapAdhemerval Zanella2021-12-151-0/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With the morecore hook removed, there is not easy way to provide huge pages support on with glibc allocator without resorting to transparent huge pages. And some users and programs do prefer to use the huge pages directly instead of THP for multiple reasons: no splitting, re-merging by the VM, no TLB shootdowns for running processes, fast allocation from the reserve pool, no competition with the rest of the processes unlike THP, no swapping all, etc. This patch extends the 'glibc.malloc.hugetlb' tunable: the value '2' means to use huge pages directly with the system default size, while a positive value means and specific page size that is matched against the supported ones by the system. Currently only memory allocated on sysmalloc() is handled, the arenas still uses the default system page size. To test is a new rule is added tests-malloc-hugetlb2, which run the addes tests with the required GLIBC_TUNABLE setting. On systems without a reserved huge pages pool, is just stress the mmap(MAP_HUGETLB) allocation failure. To improve test coverage it is required to create a pool with some allocated pages.

* malloc: Add madvise support for Transparent Huge PagesAdhemerval Zanella2021-12-151-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | Linux Transparent Huge Pages (THP) current supports three different states: 'never', 'madvise', and 'always'. The 'never' is self-explanatory and 'always' will enable THP for all anonymous pages. However, 'madvise' is still the default for some system and for such case THP will be only used if the memory range is explicity advertise by the program through a madvise(MADV_HUGEPAGE) call. To enable it a new tunable is provided, 'glibc.malloc.hugetlb', where setting to a value diffent than 0 enables the madvise call. This patch issues the madvise(MADV_HUGEPAGE) call after a successful mmap() call at sysmalloc() with sizes larger than the default huge page size. The madvise() call is disable is system does not support THP or if it has the mode set to "never" and on Linux only support one page size for THP, even if the architecture supports multiple sizes. To test is a new rule is added tests-malloc-hugetlb1, which run the addes tests with the required GLIBC_TUNABLE setting. Checked on x86_64-linux-gnu. Reviewed-by: DJ Delorie <dj@redhat.com>

The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). Only ia64 is unchanged, since it still uses the arch specific __libm_error_region on its implementation. Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.

| | | | | | | | | | | | | | | | | | | | | | | | | | Now that Hurd implementis both close_range and closefrom (f2c996597d), we can make close_range() a base ABI, and make the default closefrom() implementation on top of close_range(). The generic closefrom() implementation based on __getdtablesize() is moved to generic close_range(). On Linux it will be overriden by the auto-generation syscall while on Hurd it will be a system specific implementation. The closefrom() now calls close_range() and __closefrom_fallback(). Since on Hurd close_range() does not fail, __closefrom_fallback() is an empty static inline function set by__ASSUME_CLOSE_RANGE. The __ASSUME_CLOSE_RANGE also allows optimize Linux __closefrom_fallback() implementation when --enable-kernel=5.9 or higher is used. Finally the Linux specific tst-close_range.c is moved to io and enabled as default. The Linuxism and CLOSE_RANGE_UNSHARE are guarded so it can be built for Hurd (I have not actually test it).
