udp forward

[hwk888]

During use, UDP will not be able to receive packets from the network card, and it will wait for data, but it is normal to use it on other platforms, and I don't know what will cause it.

The UDP log output stops here, the previous UDP protocol handshake is normal, and the UDP data does not receive any data by the forwarding time。

LOG_D ("%p socks5 udp recvfrom udp", self);

adat = HEV_SOCKS5 (self)->data;
alen = sizeof (struct sockaddr_in6);
rlen = hev_task_io_socket_recvfrom (hev_socks5_udp_get_fd (self), rbuf,
                                    sizeof (rbuf), 0, adat, &alen,
                                    task_io_yielder, self);

I need more information about how to reproduce it? and which platforms works and which not?

[hwk888]

I tested on the armv7l platform, same platform, different router

[heiher]

Any more? No ideas for current info.

There is a problem with the ASUS AC1900c test, and the ASUS ax56u test is normal. The problematic test found that UDP was not successful

Does Linux kernel version 2.6.36.4brcmarm support? I run the program under the kernel, and UDP cannot be sent to the protocol stack，I found UDP to be problematic under this kernel and does not send and receive data properly

Excuse me, and I want to ask. How to start the lwip api/socket.c log, I tried several switches but could not start the module log

I'm not sure.

I suggest that you try using hev-socks5-tunnel with hev-socks5-server in UDP relay over TCP mode.

[hwk888]

I have tried this method, and the result is the same. udp can't send and receive normally.

[hwk888]

I'm running in the router system.

[heiher]

Could you paste the full logs of hev-socks5-tunnel and hev-socks5-server?

log config:

misc:
  log-file: stderr
  log-level: debug

[hwk888]

OK
