[GitHub] [nuttx] wengzhe opened a new pull request, #7969: net/devif_loopback: Add robustness to avoid infinite loop

[GitBox <gi...@apache.org>]

wengzhe opened a new pull request, #7969:
URL: https://github.com/apache/nuttx/pull/7969

   ## Summary
   When ipv4_input/ipv6_input called by devif_loopback writes wrong data into buffer (another bug we're fixing), the else block does nothing but only record the 'dropped' statistic, then infinite loop happens.
   
   Refers to previous lo device with dropping logic:
   https://github.com/apache/nuttx/blob/releases/11.0/drivers/net/loopback.c#L178-L180
   
   ## Impact
   Increase robustness, actually drop packet when we want.
   
   ## Testing
   pass CI; manually triggered edge case to check infinite loop disappears.
