wengzhe opened a new pull request, #10103:
URL: https://github.com/apache/nuttx/pull/10103

   ## Summary
   Patches included:
   - net/procfs: Simplify logic for tcp/udp stats
       1. Take out `net_ip_binding_laddr/raddr` macro
       2. `INET6_ADDRSTRLEN` is long enough for all address buffer and no need 
to
          add 0 to the end of buffer since `inet_ntop` will do so
   - net: Add `FIOC_FILEPATH` ioctl support for tcp/udp/local sockets
       - Example of `/proc/PID/group/fd`, which prints the file path:
       ```
       FD  OFLAGS  TYPE POS       PATH
       0   3       1    0         /dev/console
       1   3       1    0         /dev/console
       2   3       1    0         /dev/console
       3   3       9    0         udp:[0.0.0.0:10197<->114.118.7.163:123, tx 
0/16384, rx 0/16384, flg 1]
       4   1027    9    0         tcp:[0.0.0.0:23<->0.0.0.0:0, tx 0/16384, rx 
0/16384 + ofo 0, st 01, flg 31]
       5   67      9    0         local:[md:ap]
       ```
   
   ## Impact
   Mainly: procfs `/proc/PID/group/fd` with tcp/udp/local sockets
   Slightly: procfs `/proc/net/tcp` and `/proc/net/udp`
   
   ## Testing
   Manually
