Revision history for RPi-Serial

3.02       2026-06-12
        - Fixed a heap buffer overflow in gets(): the Perl wrapper passed a
          zero-length scalar that the XS tty_gets() then wrote up to $num_bytes
          into. tty_gets() is now a self-allocating XSUB (Newx/Safefree) that
          returns the exact bytes read
        - gets() is now binary-safe: it returns the exact bytes read (embedded
          NULs and trailing whitespace preserved) instead of running the result
          through unpack "A*"
        - tty_gets() now croaks on a read error instead of calling exit(-1),
          and clears O_NONBLOCK on the fd so the port's VTIME read timeout
          applies (short/idle reads return the partial data instead of
          spuriously failing)
