* 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>

| | | | | | | | hurd initialization stages use RUN_HOOK to run various initialization functions. That is however using absolute addresses which need to be relocated, which is done later by csu.

* malloc: Add Huge Page support for mmapAdhemerval Zanella2021-12-153-0/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Zanella2021-12-154-0/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
