Hello everyone,
For my bluetooth daemon project, called blued, I wrote a patch that
adds some HCI commands to netgraph to allow for secure simple pairing
to work. I would like to upstream my patch so my software can be used
without the end-user having to patch the kernel. I've attached my
patch for review.
If I need to create an account on Phabricator and supply my patch that
way, I can look into that instead.
Thank you for any feedback on the matter!
Cordially,
Andreas Kempe
