Hi Everyone,
Just thought I would point out that I uploaded a patch with 3 new
dissectors. Steven had reviewed my first pass at the GPS dissector
previously. I have addressed his comments inline below. I hope
everything is in order. Please let me know if I need to make any changes
for it to be merged.
Thanks,

Fixed.

\Point made, however I would like to keep a copy of the values locally
for future improvements (maybe making a cleaner text representation with
the appropriate
degrees of precision displayed). Also, if I were to skip the
tvb_get_letohl() call,
how do I make sure values are byte-swapped on big-endian systems?

Fixed.

I ran the code through a prettifier before generating the patch. It has
these style brackets now. If there are any particular
indent/astyle/whatever formatter rules you'd like me to run it through
that is fine with me. I just ran astyle --brackets=attach.
I would still like to pursue breaking PPI stuff out with a dissector
table. However I wasn't able to get to it yet, and I'd like to minimize
the amount of changes to existing code I make while committing my own
dissectors. I may get some more PPI tags shortly, that would be a good
opportunity for me to make the change.
Also, I re-ran the fuzzer (with all dissectors loaded and with a input
that triggered every field to begin with)
No events after 7k passes.
