Mark Johnston e572bc11ec Add a function, memstr, which can be used to convert a buffer of ... null-separated strings to a single string. This can be used to print the full arguments of a process using execsnoop (from the DTrace toolkit) or with the following one-liner: dtrace -n 'syscall::execve:return {trace(curpsinfo->pr_psargs);}' Note that this relies on the process arguments being cached via the struct proc, which means that it will not work for argvs longer than kern.ps_arg_cache_limit. However, the following rather non-portable script can be used to extract any argv at exec time: fbt::kern_execve:entry { printf("%s", memstr(args[1]->begin_argv, ' ', args[1]->begin_envv - args[1]->begin_argv)); } The debug.dtrace.memstr_max sysctl limits the maximum argument size to memstr(). Thanks to Brendan Gregg for helpful comments on freebsd-dtrace. Tested by: Fabian Keil (earlier version) MFC after: 2 weeks		2013-10-16 01:39:26 +00:00
