* linux: Enable vDSO for static linking as default (BZ#19767)Adhemerval Zanella2019-08-051-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch assumes static vDSO is supported as default, it is now supported on all current architectures that support vDSO. It allows removing both ALWAYS_USE_VSYSCALL define, which an architecture requires to explicit define and USE_VSYSCALL (which defines vDSO only for shared or if architecture defines ALWAYS_USE_VSYSCALL). Checked with a build against all affected ABIs. [BZ #19767] * sysdeps/unix/sysv/linux/aarch64/sysdep.h (ALWAYS_USE_VSYSCALL): Remove definition. * sysdeps/unix/sysv/linux/arm/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86/libc-vdso.h: Remove #if USE_VSYSCALL. * sysdeps/unix/sysv/linux/sysdep-vdso.h: Likewise. * sysdeps/unix/sysv/linux/sysdep.h (ALWAYS_USE_VSYSCALL, USE_VSYSCALL): Remove defitions.

* Enable VDSO on x86_64 statically linked programs [BZ #19767]Rafael Ávila de Espíndola2018-11-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the required code already existed, and some of it was already running. AT_SYSINFO_EHDR is processed if NEED_DL_SYSINFO_DSO is defined, but it looks like it always is. The call to setup_vdso is also unconditional, so all that was left to do was setup the function pointers and use them. This patch just deletes some #ifdef to enable that.

* x86-64/CET: Extend ucontext_t to save shadow stackH.J. Lu2018-07-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a field to ucontext_t to save shadow stack: 1. getcontext and swapcontext are updated to save the caller's shadow stack pointer and return addresses. 2. setcontext and swapcontext are updated to restore shadow stack and jump to new context directly. 3. makecontext is updated to allocate a new shadow stack and set the caller's return address to __start_context. Since makecontext allocates a new shadow stack when making a new context and kernel allocates a new shadow stack for clone/fork/vfork syscalls, we track the current shadow stack base. In setcontext and swapcontext, if the target shadow stack base is the same as the current shadow stack base, we unwind the shadow stack. Otherwise it is a stack switch and we look for a restore token. We enable shadow stack at run-time only if program and all used shared objects, including dlopened ones, are shadow stack enabled, which means that they must be compiled with GCC 8 or above and glibc 2.28 or above. We need to save and restore shadow stack only if shadow stack is enabled. When caller of getcontext, setcontext, swapcontext and makecontext is compiled with smaller ucontext_t, shadow stack won't be enabled at run-time. We check if shadow stack is enabled before accessing the extended field in ucontext_t.

* Linux: Consolidate {RTLD_}SINGLE_THREAD_P definitionAdhemerval Zanella2017-10-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current GLIBC has two ways to implement the single thread optimization on syscalls to avoid calling the cancellation path: either by using global variables (__{libc,pthread}_multiple_thread) or by accessing the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB). Both the variables and the macros to acces its value are defined in the architecture sysdep-cancel.h header. This patch consolidates its definition on only one header, sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define (SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer to use the global variables instead of the TCB field. This is an optimization, so if the architecture does not define it, the TCB method will be used as default.

* Fix {INLINE,INTERNAL}_SYSCALL macros for x32Adhemerval Zanella2017-08-221-109/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem for x32 is the {INTERNAL,INLINE}_SYSCALL C macros explicit cast the arguments to 'long int', thus passing as 32 bits arguments that should be passed to 64 bits. Previous x32 implementation uses the auto-generated syscalls from assembly macros (syscalls.list), so the {INTERNAL,INLINE}_SYSCALL macros are never used with 64 bit argument in x32 (which are internally broken for this ILP). To fix it I used a strategy similar to MIPS64n32 (although both ABI differs for some syscalls on how top pass 64-bits arguments) where argument types for kernel call are defined using GCC extension 'typeof' with a arithmetic operation. This allows 64-bits arguments to be defined while 32-bits argument will still passed as 32-bits. I also cleanup the {INLINE,INTERNAL}_SYSCALL definition by defining 'inline_syscallX' instead of constructing the argument passing using macros (it adds some readability) and removed the ununsed INTERNAL_SYSCALL_NCS_TYPES define (since the patch idea is exactly to avoid requiric explicit types passing).

* x86-64: Update LO_HI_LONG for p{readv,writev}{64}v2H.J. Lu2017-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel interface for p{readv,writev}{64}v is (unsigned long fd, {const }struct iovec *iov, unsigned long vlen, unsigned long pos_l, unsigned long pos_h) Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64 and __ARCH_WANT_COMPAT_SYS_PWRITEV64, (unsigned long fd, {const }struct iovec *iov, unsigned long vlen, off64_t pos) is used for p{readv,writev}{64}v. X32 is the only such target. The LO_HI_LONG macro is used to pass offset to the pos_l and pos_h pair. Since pos_h is ignored when size of offset == sizeof of pos_l, x86-64 has #define LO_HI_LONG(val) (val) But the kernel interface for p{readv,writev}{64}v2 is (unsigned long fd, {const }struct iovec *iov, unsigned long vlen, unsigned long pos_l, unsigned long pos_h, int flags) Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64V2 and __ARCH_WANT_COMPAT_SYS_PWRITEV64V2, (unsigned long fd, {const }struct iovec *iov, unsigned long vlen, off64_t pos, int flags) is used for p{readv,writev}{64}v2. X32 is the only such target. Update x86-64 LO_HI_LONG to pass 0 as the high part of the offset argument for p{readv,writev}{64}v2 and define a different LO_HI_LONG for x32 to only pass one argument for offset. Tested on x32 and x86-64. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (LO_HI_LONG): Pass 0 as the high part of offset. * sysdeps/unix/sysv/linux/x86_64/x32/sysdep.h (LO_HI_LONG): New.

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg.

* Consolidate sched_getcpuAdhemerval Zanella2015-06-091-0/+1
| | | | | | | | This patch consolidates the sched_getcpu implementations across all arches (except tile, which requires its own). This patch removes the powerpc, x86_64 and x32 specific files and change the default linux one to use INLINE_VSYSCALL where possible (for ports that implements it).

* Consolidate vDSO macros and usageAdhemerval Zanella2015-05-261-55/+0
| | | | | | | | | | | | | | | | This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.
