Hi there, I'm following the security advisory to patch the cpio vulnerability (update to 6_0_0 RELENG p2, make obj, make depend), yet when it comes to make, it shows some error message as follows: /usr/src/gnu/usr.bin/cpio/../../../contrib/cpio/copyin.c:536: error: redefinition of 'safer_name_suffix' /usr/src/gnu/usr.bin/cpio/../../../contrib/cpio/copyin.c:488: error: previous

Hi I encountered this problem a few times in the past, but only now it is consistent enough so I can write this email. In short, the problem is that after I copy some structure from the profiled program to the dtrace space, and set a "this-dataP" variable to point to the local copy, after a while some of the fields of the local structure are overridden with junk values. In

Hi, I have a situation where a DTrace script is printing out extra characters, despite the copyin() call giving a specific length. Can anyone think of why this might be? It''s fine the first time all of the probes fire, but on a second run of my generating operations, I get junk in there. For example: set setop length 5, FOUND KEY, STORED set setop length 5, FOUND KEY, STORED get

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...

...teh h_alias array the other entries in the array get corrupted. So I have ended up with this script: #!/usr/bin/dtrace -CZs #include <netdb.h> pid$target::gethostbyname_r:return { self->r = (struct hostent *)copyin(arg1, sizeof (struct hostent)); printf("%d Host: %s", pid, copyinstr((uintptr_t)self->r->h_name)); printf(" h_aliases %p ", self->r->h_aliases); self->a = (char **)copyin((uintptr_t)self->r->h_aliases, 4*sizeof (char *)); } #define ALIAS(X) \ pid$target::gethostbyname_r:return \ / self->a[X] != 0 / \ { \ printf("%d h_ali...

I have a clause that look like this: syscall::write:entry /execname == "ntpd" && self->recspec/ { speculate(self->recspec); printf(" fd=%d buf=%d\n%s",arg0,arg2, stringof(copyin(arg1,arg2-1))); } The ntpd program always write a \n trminated string in this context, so I used the "arg2-1" to drop the \n. This works

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

[1] Predicates in one-liners I would like to list the probe modules in my executable and then dynamically create a dscript to trace execution of those modules alone (by excluding the 3rd party and system libraries). I tried the below script without success. The conditional given in the predicate is not taking effect. Why is this so ? $ dtrace -ln ''pid$target:::

Hi Expert I want to use dtrace to monitor the content change of one file. I made following scripts, #!/usr/sbin/dtrace -s inline int MYPID = $1; syscall::write:entry /pid == MYPID/ { tracemem(arg1, arg2); printf("\n"); } It always has an following error bash-3.00$ sudo dumpFIFO.dtrace 3836 dtrace: failed to compile script ./dumpFIFO.dtrace: line 19: tracemem( ) argument #2

ive been using wine for about a month now and ive tried a couple different versions but i cant install or run anything on wine from a CD..i did a work around for it by just copyin the cd to my hard drive and got my game installed, but it comes with 3 play disks and an install disk, and when i try to play it even when the correct play disk is in and copied everywhere on my hard drive the game still

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?

hi, I''m using the PID provider to trace a 32-bit app, prtdiag. I''m trying to print the value of "propname" (arg1) in the following func: int picl_get_propval_by_name(picl_nodehdl_t nodeh, const char *propname, void *valbuf, size_t nbytes) ... i''ve tried many versions, but this is a representative one: 53 this string propname; 54 55

There is a Slashdot discussion today titled "Cambridge Researcher Breaks OpenBSD Systrace". Slashdot anonymous member has a comment "Even Sun''s Dtrace might be vulnerable." I don''t think it is.

Hi all, OK, so this at first looked like a clear cut "Don''t do it, or at worst handle the results" issue my customer has come to me with, but the more we discuss it, the more it looks like we should have better ways of dealing with this issue. > We have user defined dtrace probe points in the application which use > as parameter 64 bit values: > > provider adv {

Howdy, I am trying to migrate several scripts to use application defined types, and am running into a few issues. When I attempt to run a script with a application defined type, it looks like the DTrace preprocessor is getting angry with me: $ cat view.d #include "httpd.h" :::acceptconnection { this->addr = (conn_rec *)copyin(arg0,sizeof(conn_rec *)); } $ dtrace -C

Hi. I've configured a Samba PDC controller on which I've configured a couple of printers using Cups.
