I''ve been trying to get access to a userland string that''s behind a second level pointer using DTrace, but I can''t seem to get it to work. I started with the example on the Team DTrace Tips and Tricks slides: trace(copyinstr(*(uintptr_t *)copyin(arg0, curpsinfo->pr_dmodel == PR_MODEL_ILP32 ? 4 : 8))); And when I couldn''t get it to work, I started breaking it down into smaller pieces to see what was going on at each step. Here''s the "C" and "D" code: --- pt.c --- static int sz = sizeof(char *); main() { c...

I would like to know how to get access to errno when using pid provider to probe calls to libc functions like fopen(). The built-in errno appears to be only for system calls. What I''d like to be able to do is investigate where in an application I''m encountering EMFILE and what the stack looks like at the time. This message posted from opensolaris.org

Hi I have a Dtrace script ( attached ) which examines memory usage, using fbt:genunix:anon_resvmem:entry & return On my T2000 it totals the 65k pages being reserved by my application, printing out the total in bytes. Seems to work well, tested with a small app that malloced < 65 K, malloced 200M and mmapeed a 16M file and it appeared to get things correct. Could I just get a second pair

I''m interested in monitoring the amount of stack used by a multi-threaded program. I assume ''stackdepth'' built-in would be useful...but not sure. Been through demo''s, ToolKit, and internals..but it''s just not clicking for me yet. Not sure how to measure start/end of stack size dynamically...Anyone know how to break this down?

hi fnds, i want to print the filenames on which the stat system call is acting when a stat system call is invoked. can anyone can help me this regard. Thanks jeevan

Hi all, I am trying to write a D script which would print ustack() for every program in the system receiving SIGSEGV. All the stacks printed in trap()/sigtoproc() context do not have meaningful symbols. The following solves the problem to some degree but I''d much rather have a self-contained D script. dtrace -w -n ''fbt:genunix:sigtoproc:entry/arg2 == 11/ {

...and an explanation of how the args work if i''m missing something Thanks James Dickens information relied on: from socketsize.d /* ** Process Socket Write */ fbt:sockfs:so_update_attrs:entry /arg1 == 1/ { /* fetch details */ this->size = arg3; cmd = (string)curpsinfo->pr_psargs; /* store details */ @Size[pid,cmd] = quantize(this->size); } from src/src/uts/common/fs/sockfs/socksubr.c void so_update_attrs(struct sonode *so, int flag) _______________________________________________ DTrace mailing list DTrace@opensolaris.org https://www.ope...

Hi, I am tracking down a problem and would like to know how I can follow a forked process with my dtrace script, or how I can trace a dynamic library. Here is the problem. I am tracing dtlogin, and specifically I am trying to determine what error libpkcs11`<routine> is returning. It turns out dtlogin forks a lot of processes, and I believe the second forked process is the one that winds
