* powerpc: Remove backtrace implementationAdhemerval Zanella2021-10-201-133/+0
| | | | | | | | | | | | | | | The powerpc optimization to provide a fast stacktrace requires some ad-hoc code to handle Linux signal frames and the change is fragile once the kernel decides to slight change its execution sequence [1]. The generic implementation work as-is and it should be future proof since the kernel provides the expected CFI directives in vDSO shared page. Checked on powerpc-linux-gnu, powerpc64le-linux-gnu, and powerpc64-linux-gnu. [1] https://sourceware.org/pipermail/libc-alpha/2021-January/122027.html

| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master
* Fix array overflow in backtrace on PowerPC (bug 25423)Andreas Schwab2020-01-211-0/+2
| | | | | | When unwinding through a signal frame the backtrace function on PowerPC didn't check array bounds when storing the frame address. Fixes commit d400dcac5e ("PowerPC: fix backtrace to handle signal trampolines").
* elf: Move vDSO setup to rtld (BZ#24967)Adhemerval Zanella2020-01-031-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch moves the vDSO setup from libc to loader code, just after the vDSO link_map setup. For static case the initialization is moved to _dl_non_dynamic_init instead. Instead of using the mangled pointer, the vDSO data is set as attribute_relro (on _rtld_global_ro for shared or _dl_vdso_* for static). It is read-only even with partial relro. It fixes BZ#24967 now that the vDSO pointer is setup earlier than malloc interposition is called. Also, vDSO calls should not be a problem for static dlopen as indicated by BZ#20802. The vDSO pointer would be zero-initialized and the syscall will be issued instead. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, s390x-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. I also run some tests on mips. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* Refactor vDSO initialization codeAdhemerval Zanella2019-09-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux vDSO initialization code the internal function pointers require a lot of duplicated boilerplate over different architectures. This patch aims to simplify not only the code but the required definition to enable a vDSO symbol. The changes are: 1. Consolidate all init-first.c on only one implementation and enable the symbol based on HAVE_*_VSYSCALL existence. 2. Set the HAVE_*_VSYSCALL to the architecture expected names string. 3. Add a new internal implementation, get_vdso_mangle_symbol, which returns a mangled function pointer. Currently the clock_gettime, clock_getres, gettimeofday, getcpu, and time are handled in an arch-independent way, powerpc still uses some arch-specific vDSO symbol handled in a specific init-first implementation.

* Rename struct ucontext tag (bug 21457).Joseph Myers2017-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed. Tested for x86_64, and with build-many-glibcs.py.

* powerpc: Fix signal handling in backtraceAdhemerval Zanella2017-05-111-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now with read consolidation which uses SYSCALL_CANCEL macro, a frame pointer is created in the syscall code and this makes the powerpc backtrace obtain a bogus entry for the signal handling patch. It is because it does not setup the correct frame pointer register (r1) based on the saved value from the kernel sigreturn. It was not failing because the syscall frame pointer register was the same one for the next frame (the function that actually called the syscall). This patch fixes it by setup the next stack frame using the saved one by the kernel sigreturn. It fixes tst-backtrace{5,6} from the read consolidation patch. Checked on powerpc-linux-gnu and powerpc64le-linux-gnu. * sysdeps/powerpc/powerpc32/backtrace.c (is_sigtramp_address): Use void* for argument type and use VDSO_SYMBOL macro.
