[PATCH] ptrace: Add compat PTRACE_{G,S}ETSIGMASK handlers

2017-06-29 Thread James Morse
compat_ptrace_request() lacks handlers for PTRACE_{G,S}ETSIGMASK, instead using those in ptrace_request(). The compat variant should read a compat_sigset_t from userspace instead of ptrace_request()s sigset_t. While compat_sigset_t is the same size as sigset_t, it is defined as 2xu32, instead of a
