Subject: Properly initialize siginfo_t object passed to print_stopped function
X-Git-Tag: v4.11~184
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=135f5cf634b2fbf3b10f3f5c9c596418fbd07273;p=strace

Properly initialize siginfo_t object passed to print_stopped function

* strace.c (trace): Clear the whole siginfo_t variable before passing it
to ptrace(PTRACE_GETSIGINFO) because the latter may initialize only a
part of the structure.
