------------------------------------------
[~aw], I quoted wine source code for reference. Not to use their code as-is.
BTW wine is under LGPL.
You can find similar approach to get platform specific thread id in lots of
other implementations also. I hope there should not be any license issues for
the patch.
[~trtrmitya], In my opinion we should include platform specific code that we
can actually compile and test on. Adding Solaris specific code is possible, I
have also seen few JIRA related to that. But not sure who can compile and
verify on Solaris. Did FreeBSD specific code work for you?
Let me know if Solaris specific code is needed.

> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.6.0

> In OpensslSecureRandom.c you use Linux-specific syscall gettid():
> static unsigned long pthreads_thread_id(void)
> {
> return (unsigned long)syscall(SYS_gettid);
> }
> Man page says:
> gettid() is Linux-specific and should not be used in programs that are
> intended to be portable.
> This breaks hadoop-2.6.0 compilation on FreeBSD (may be on other OSes too).
