* Add IPV6_MULTICAST_ALL from Linux 4.20 to bits/in.h.Joseph Myers2019-01-011-0/+1
| | | | | | | | | | This patch adds the IPV6_MULTICAST_ALL constant from Linux 4.20 to bits/in.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_MULTICAST_ALL): New macro.
* Add PACKET_IGNORE_OUTGOING from Linux 4.20 to netpacket/packet.h.Joseph Myers2019-01-011-0/+1
| | | | | | | | | | This patch adds the PACKET_IGNORE_OUTGOING constant from Linux 4.20 to netpacket/packet.h. Tested for x86_64. * sysdeps/unix/sysv/linux/netpacket/packet.h (PACKET_IGNORE_OUTGOING): New macro.
* Add HWCAP_SSBS from Linux 4.20 to AArch64 bits/hwcap.h.Joseph Myers2019-01-011-0/+1
| | | | | | | | | | This patch adds the HWCAP_SSBS constant from Linux 4.20 to the AArch64 bits/hwcap.h. Tested with build-many-glibcs.py for aarch64-linux-gnu. * sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SSBS): New macro.
* Update syscall-names.list for Linux 4.20.Joseph Myers2019-01-011-2/+3
| | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 4.20. Although there are no new syscalls, the riscv_flush_icache syscall has moved to asm/unistd.h (previously in asm/syscalls.h) and so now needs to be added to the list. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 4.20. (riscv_flush_icache): New syscall.

* riscv: Use __has_include__ to include <asm/syscalls.h> [BZ #24022]H.J. Lu2018-12-311-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <asm/syscalls.h> has been removed by commit 27f8899d6002e11a6e2d995e29b8deab5aa9cc25 Author: David Abdurachmanov <david.abdurachmanov@gmail.com> Date: Thu Nov 8 20:02:39 2018 +0100 riscv: add asm/unistd.h UAPI header Marcin Juszkiewicz reported issues while generating syscall table for riscv using 4.20-rc1. The patch refactors our unistd.h files to match some other architectures. - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h - Adjust kernel asm/unistd.h So now asm/unistd.h UAPI header should show all syscalls for riscv. <asm/syscalls.h> may be restored by Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header Date: Tue, 11 Dec 2018 09:09:35 +0100 UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header, which did resolve issue with missing syscalls macros resulting in glibc (2.28) build failure. It also broke glibc in a different way: asm/syscalls.h is being used by glibc. I noticed this while doing Fedora 30/Rawhide mass rebuild. The patch returns asm/syscalls.h header and incl. it into asm/unistd.h. I plan to send a patch to glibc to use asm/unistd.h instead of asm/syscalls.h In the meantime, we use __has_include__, which was added to GCC 5, to check if <asm/syscalls.h> exists before including it. Tested with build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7. [BZ #24022] * sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if <asm/syscalls.h> exists with __has_include__ before including it.

* Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers2018-12-212-0/+3
| | | | | | | | | | | | | | | | | | | | | | The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations.

* Remove x86 mathinline.h.Joseph Myers2018-12-192-295/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After previous cleanups, the only code in the x86 bits/mathinline.h that is relevant with current compilers is the inline of __ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES (i.e. for when libm itself is being built). This inline is something that does belong in glibc not GCC, since __ieee754_atan2l is a purely internal function name. This patch moves that inline to a new sysdeps/x86/fpu/math_private.h, removing the bits/mathinline.h header. Note that previously the inline was only for non-SSE 32-bit x86. That condition does not make sense, however, for a long double function; if it's not inlined, exactly the same x87 instruction will end up getting used by the out-of-line function, for both 32-bit and 64-bit. So that condition is not retained in the new version. Tested for x86_64 and x86. As expected, installed stripped shared libraries are unchanged for 32-bit x86, but installed stripped libm.so is changed for x86_64 because calls to __ieee754_atan2l start being inlined where previously they were out of line calls. (The same change to start inlining the function would presumably also apply for 32-bit built with -mfpmath=sse, but that's not a configuration I've tested.) * sysdeps/x86/fpu/math_private.h: New file. * sysdeps/x86/fpu/bits/mathinline.h: Remove.
* Remove x86 mathinline.h sinh, cosh, tanh inlines.Joseph Myers2018-12-191-16/+0
| | | | | | | | | | | | | | | | | | | | | | Continuing the removal of bits/mathinline.h inlines that would better be done by the compiler, this patch removes x86 inlines for sinh, cosh and tanh functions (inlines only previously present for fast-math, non-SSE 32-bit x86). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such inlines as an optimization in GCC. I believe the only remaining part of the x86 bits/mathinline.h that does anything useful with current compilers after this patch is the __LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to remove the whole header and move that inline to a sysdeps math_private.h header in a subsequent patch. Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline definition. (cosh): Likewise. (tanh): Likewise.
* Print cache size and geometry auxv types on LD_SHOW_AUXV=1Tulio Magno Quites Machado Filho2018-12-191-2/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when LD_SHOW_AUXV=1.

However different than sparc, alpha defines the restorer as the 5th argument (sparc defines as the 4th).

This patch fixes it by using the Linux generic definition meant for the RT kernel ABI. Checked the signal tests on emulated m68-linux-gnu (Aranym). It fixes the faulty signal/tst-sigaction and man works as expected. Adhemerval Zanella <adhemerval.zanella@linaro.org> James Clarke <jrtc27@jrtc27.com> [BZ #23960] * sysdeps/unix/sysv/linux/kernel_sigaction.h (HAS_SA_RESTORER): Define if SA_RESTORER is defined.

* Remove __ASSUME_ST_INO_64_BIT.Joseph Myers2018-12-187-43/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment "However, SH is lame, and still does not have a 64-bit inode field.". The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha case is, however, trivially useless: none of the files that test __ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel support for stat64 syscalls, with a 64-bit st_ino field, in Linux 2.6.4; the define to 0 for Alpha in glibc predates that). The SH kernel gained support for a 64-bit st_ino in struct stat64 in commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64() syscall."), which is in Linux 2.6.22 and later. So the redefinition of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of the files testing it do so immediately after a stat64-family syscall has been used, which will always have set the 64-bit st_ino correctly (in addition to the 32-bit __st_ino), while the relevant code __xstat32_conv executes only after such a syscall in the function calling __xstat32_conv. Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it. Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases around it identical, so that conditional is also removed. Tested compilation with build-many-glibcs.py for its Alpha and SH configurations; also ran the glibc testsuite for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT): Remove macro definition. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_ST_INO_64_BIT): Do not undefine and define. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_ST_INO_64_BIT): Likewise. * sysdeps/unix/sysv/linux/fxstat64.c: Do not include <kernel-features.h>.

* S390: Cleanup ifunc-resolve.h.Stefan Liebler2018-12-186-41/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ifunc macros s390_vx_libc* are no longer used and can be removed as all users are now relying on s390_libc_ifunc_expr. The same applies to s390_libc_ifunc. The macro s390_libc_ifunc_init is now renamed to s390_libc_ifunc_expr_stfle_init and the users are adjusted accordingly. ChangeLog: * sysdeps/s390/multiarch/ifunc-resolve.h (s390_vx_libc_ifunc, s390_vx_libc_ifunc_redirected, s390_vx_libc_ifunc2, s390_vx_libc_ifunc_init, s390_vx_libc_ifunc2_redirected, s390_libc_ifunc): Delete macro definition.
