* Get the kernel module file name rather than hard-coding it like on Solaris.
* Use FreeBSD's process library API.
* Handle FreeBSD's different lock types.
* Get the list of loaded providers via a syscall.
* There are a few placeholders in here for which there isn't libproc
support code yet. This is relevent to userland tracing. This set of
commits is designed to get kernel tracing up and running, with the
userland stuff to follow later.
error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.
Add a couple of functions to get and set the error location which can
be optionally compiled into the library.
* Handle the different ioctl design.
* Support the freopen() changes.
* Use functions in FreeBSD's process library rather than the CDDL
library that Solaris has which sits on top of their process file
system and is therefore unsuitable for use on FreeBSD. The libproc
API for FreeBSD is deliberately different to that on Solaris because
Sun wouldn't release the libproc.h header under a BSD license.
* On FreeBSD define both LITTLE_ENDIAN and BIG_ENDIAN and then set the
BYTE_ORDER to the one we are using. On Solaris they define one or
the other but not both. For us to keep using FreeBSD header files,
we need to use endian definitions the same way we do in pure BSD
code.
use 'const' and just override it whenever we feel like it. If we use
it at all, then we need to do it properly.
Add a couple of functions that were useful in getting this code ported.
* Use the FreeBSD shell.
* On FreeBSD the tests run from the OBJDIR, so output files go there
rather than in the source tree like they do on Solaris.
* FreeBSD doesn't need a special path to the compiler.
OpenSolaris. This commit resets files to match the versions in the
OpenSolaris tree as of 2008/04/10.
The changes in this import from the previous import are the ones that
will subsequently re-applied to take files off the vendor branch. This
is unfortunately necessary because the Solaris developers won't allow
FreeBSD support #ifdefs in their source code because that creates
'dead code' (stuff that they never compile).
and show up with different names: first try to open provider using
remembered name and compare its ident, if equal, this is our provider,
if not equal or there is no provider with such name, find provider with
remembered ident and don't care about the name.
