I have a very recent kernel (with the latest procfs fixes from Sean) and it
has KTRACE defined in it. The main problem I have is that truss does
execute the command but doesn't show anything...
Running this:
203 [20:30] roberto@keltia:~> truss /bin/echo foo
cannot set PF_LINGER: Inappropriate ioctl for device
foo
^C
...and sits there till I kill it.
Sources from CTM delta cvs-cur #3883 1997/12/09 14:11:27. Make world done
yesterday.
Is there a problem between KTRACE and truss ? What did I miss ?
Latest patch from Sean is this one:
sef 1997/12/08 21:03:43 PST
Modified files:
sys/miscfs/procfs procfs_subr.c
Log:
Code to prevent a panic caused by procfs_exit(). Note that i don't know
what is teh root cause -- but, sometimes, a procfs vnode in pfshead is
apparantly corrupt (or a UFS vnode instead). Without this patch, I can
get it to panic by doing (in csh)
Kernel config. file available on demand.
