Subjectstrace BROKEN since 1.3.96
Date

Hi!

Kernel 1.3.96 breaks strace-3.0.8, because strace
reads "/proc/<pid>/mem" to access a tasks memory.

Reading this file seems to be no longer permitted,
except for the task <pid> itself.

What access method for the data segment of a process should we use?

As a quick fix I copied the oldway for SUNOS4, using request
PTRACE_PEEKDATA for ptrace (function "umoven" in file "util.c").

Surprisingly it works!
