* libgo: handle linking to NetBSD's versioned symbolsNikhil Benesch2020-10-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On NetBSD, for backwards compatibility, various libc symbols are renamed to a symbol with a version suffix. For example, this is the (abbreviated) definition of sigaction: int sigaction(...) __asm__ ("__sigaction14") This poses a challenge for libgo, which attempts to link sigaction by way of an "//extern" comment: //extern sigaction func sigaction(...) This results in a reference to the deprecated compatibility symbol "sigaction", rather than the desired "__sigaction14" symbol. This patch introduces a new "//extern-sysinfo" comment to handle this situation. The new mklinknames.awk script scans a package for these comments and outputs a "//go:linkname" directive that links the wrapper to the correct versioned symbol, as determined by parsing the __asm__ annotation on the function's declaration in gen-sysinfo.go. For now, only the following packages are scanned by mklinknames.awk: os os/user runtime syscall gotools/: * Makefile.am (check-runtime): Add runtime_linknames.go to --extrafiles. * Makefile.in: Regenerate.

* syscall: only compile ptrace varargs shim on LinuxNikhil Benesch2020-10-2112-14/+14
| | | | | | | | | | | | | | Only compile the __go_ptrace varargs shim on Linux to avoid compilation failures on some other platforms. The C ptrace function is not entirely portable (e.g., NetBSD has `int data` instead of `void* data`), and so far Linux is the only platform that needs the varargs shim. Additionally, make the types in the ptrace and raw_ptrace function declarations match. This makes it more clear that the only difference between the two is that calls via the former are allowed to block while calls via the latter are not.

* libgo: fix ptrace syscall hooks into glibcPaul E. Murphy2020-09-172-2/+2
| | | | | | | | | | | | | | | | | | ptrace is actually declared as a variadic function. On ppc64le the ABI requires to the caller to allocate space for the parameters and allows the caller to modify them. On ppc64le, depending on how and what version of GCC is used, it will save to parameter save area. This happened to clobber a saved LR, and caused syscall.TestExecPtrace to fail with a timeout when the tracee segfaults, and waits for the parent process to inspect. Wrap this function to avoid directly calling glibc's ptrace from go. Fixes golang/go#36698 Fixes go/92567 Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/254755
