search for: siginfo_t

I now have a Solaris account and I''ve been able to try out my DT_Logger code there. I ran into several issues, but the one I''m stuck on (though working around :-) is the need for a much simplified siginfo_t definition. I looked at /usr/include/sys/siginfo.h, but I can''t figure out what the maze of #ifdefs would actually resolve to, so I don''t know which data elements I can ask dtrace to print. Could someone point me to a more straightforward definition? -r -- http://www.cfcl.com/...

Currently the blacklist is maintained by hand in kprobes.c which is separated from the function definition and is hard to catch up the kernel update. To solve this issue, I've tried to implement new NOKPROBE_SYMBOL() macro for making kprobe blacklist at build time. Since the NOKPROBE_SYMBOL() macros can be placed right after the function is defined, it is easy to maintain. This series
