William San Filippo resolved MYNEWT-119.
----------------------------------------
Resolution: Fixed
> Nimble stack crashing if PHY receives a PDU that is 257 bytes long.
> -------------------------------------------------------------------
>
> Key: MYNEWT-119
> URL: https://issues.apache.org/jira/browse/MYNEWT-119
> Project: Mynewt
> Issue Type: Bug
> Components: Nimble
> Affects Versions: v0_8_0_beta1
> Reporter: William San Filippo
> Assignee: William San Filippo
> Priority: Blocker
> Labels: controller, mbuf
> Fix For: v0_8_0_beta2
>
>
> There is a bug in the code which will cause the device to crash if it
> receives a mbuf that is too large. Unfortunately I dont have a debug output
> of the crash but we could obtain one if we think it is necessary. Running the
> un-fixed code in a noisy environment with lots of simultaneous connections
> should reproduce it eventually.
> This problem was caused when we moved the controller code to use msys mbufs.
> The buffer was not sized properly as the PHY still needs a flat buffer to
> receive into and since the PHY currently uses mbufs, these mbufs need to
> accommodate at least 257 bytes of data (they only had 256 bytes).
