In investigating a hang in kcfd, I wanted to find the call path to
libxml2's xmlInitParser() routine. So, under snv89, I invoked dtrace:
# dtrace -n 'pid$target::xmlInitParser:entry { ustack(); }' \
-c 'elfsign verify -v /usr/lib/security/pkcs11_kernel.so.1'
dtrace: invalid probe specifier pid$target::xmlInitParser:entry { ustack(); }:
probe description pid2794::xmlInitParser:entry does not match any probes
elfsign: verification of /usr/lib/security/pkcs11_kernel.so.1 passed.
...
Specifying the libxml2.so.2 module doesn't help. Removing the function
name altogether does result in a probe at libxml2.so.2`xmlInitParser,
but I have to search through an exhaustive list of all function calls.
How do I narrow my probe specification?
Thanks -JZ
