2021-12-17powerpc64[le]: Allocate extra stack frame on syscall.SMatheus Castanho1-0/+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.

2021-12-17nss: Use "files dns" as the default for the hosts database (bug 28700)Florian Weimer3-6/+5
This matches what is currently in nss/nsswitch.conf. The new ordering matches what most distributions use in their installed configuration files. It is common to add localhost to /etc/hosts because the name does not exist in the DNS, but is commonly used as a host name. With the built-in "dns [!UNAVAIL=return] files" default, dns is searched first and provides an answer for "localhost" (NXDOMAIN). We never look at the files database as a result, so the contents of /etc/hosts is ignored. This means that "getent hosts localhost" fail without a /etc/nsswitch.conf file, even though the host name is listed in /etc/hosts. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

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.

2021-12-16Remove upper limit on tunable MALLOC_MMAP_THRESHOLDPatrick McGehearty1-10/+5
The current limit on MALLOC_MMAP_THRESHOLD is either 1 Mbyte (for 32-bit apps) or 32 Mbytes (for 64-bit apps). This value was set by a patch dated 2006 (15 years ago). Attempts to set the threshold higher are currently ignored. The default behavior is appropriate for many highly parallel applications where many processes or threads are sharing RAM. In other situations where the number of active processes or threads closely matches the number of cores, a much higher limit may be desired by the application designer. By today's standards on personal computers and small servers, 2 Gbytes of RAM per core is commonly available. On larger systems 4 Gbytes or more of RAM is sometimes available. Instead of raising the limit to match current needs, this patch proposes to remove the limit of the tunable, leaving the decision up to the user of a tunable to judge the best value for their needs. This patch does not change any of the defaults for malloc tunables, retaining the current behavior of the dynamic malloc mmap threshold. bugzilla 27801 - Remove upper limit on tunable MALLOC_MMAP_THRESHOLD Reviewed-by: DJ Delorie <dj@redhat.com> malloc/ malloc.c changed do_set_mmap_threshold to remove test for HEAP_MAX_SIZE.

Starting with commit b05fae4d8e34604a72ee36d2d3164391b76fcf0b "elf: Use the minimal malloc on tunables_strdup", I get lots of segfaults in static tests on s390x when also using, e.g.: export GLIBC_TUNABLES="glibc.elision.enable=1" tunables_strdup callls __minimal_malloc which tries to call __mmap due to insufficient space left. __mmap itself first setups a new stack frame and segfaults when copying the stack-protector canary from thread-pointer.

2021-12-15malloc: Add Huge Page support to arenasAdhemerval Zanella3-44/+99
It is enabled as default for glibc.malloc.hugetlb set to 2 or higher. It also uses a non configurable minimum value and maximum value, currently set respectively to 1 and 4 selected huge page size. The arena allocation with huge pages does not use MAP_NORESERVE. As indicate by kernel internal documentation [1], the flag might trigger a SIGBUS on soft page faults if at memory access there is no left pages in the pool. 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. Checked on x86_64-linux-gnu with no reserved pages, 10 reserved pages (which trigger mmap(MAP_HUGETBL) failures) and with 256 reserved pages (which does not trigger mmap(MAP_HUGETLB) failures).

2021-12-15malloc: Add Huge Page support for mmapAdhemerval Zanella11-15/+207
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.

2021-12-15malloc: Add madvise support for Transparent Huge PagesAdhemerval Zanella13-0/+259
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 error handling is moved to sysdeps/ieee754 version with no SVID support. 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.
2021-12-13math: Use fmin/fmax on hypotWilco Dijkstra1-2/+3
It optimizes for architectures that provides fast builtins. Checked on aarch64-linux-gnu.
2021-12-13aarch64: Add math-use-builtins-f{max,min}.hAdhemerval Zanella6-112/+8
It allows to remove the arch-specific implementations.
2021-12-13math: Add math-use-builtinds-fmin.hAdhemerval Zanella3-0/+10
It allows the architecture to use the builtin instead of generic implementation.
2021-12-13math: Add math-use-builtinds-fmax.hAdhemerval Zanella7-0/+14
It allows the architecture to use the builtin instead of generic implementation.
2021-12-13math: Remove powerpc e_hypotAdhemerval Zanella9-327/+1
The generic implementation is shows only slight worse performance: POWER10 reciprocal-throughput latency master 8.28478 13.7253 new hypot 7.21945 13.1933 POWER9 reciprocal-throughput latency master 13.4024 14.0967 new hypot 14.8479 15.8061 POWER8 reciprocal-throughput latency master 15.5767 16.8885 new hypot 16.5371 18.4057 One way to improve might to make gcc generate xsmaxdp/xsmindp for fmax/fmin (it onl does for -ffast-math, clang does for default options). Checked on powerpc64-linux-gnu (power8) and powerpc64le-linux-gnu (power9).
2021-12-13i386: Move hypot implementation to CAdhemerval Zanella3-139/+48
The generic hypotf is slight slower, mostly due the tricks the assembly does to optimize the isinf/isnan/issignaling. The generic hypot is way slower, since the optimized implementation uses the i386 default excessive precision to issue the operation directly. A similar implementation is provided instead of using the generic implementation: Checked on i686-linux-gnu.
