Hi,
Here's a set of patches I've ended up creating today due to various
issues found with LE security handling. Most of the issues fixed have
been in the three for a bit longer time, but the issue fixed by 3/6 was
introduced (by me) by the change to use passkey notification instead of
confirmation.
I've left the LTK re-encryption removal to be the last patch since it
can be debated whether we want it or not. I've on occasion had quite
many LTK re-encryption failures when testing against my iPhone, but
mostly it works just fine. Removing the re-encryption drops the failures
to 0. Today I kept getting local failures (Start Encrypt cmd_status)
constantly with local Intel Bluetooth hardware and a Bluetooth mouse.
Removing the re-encryption made this work again.
