Re: inconsistent wget behavior
Hi Fabio, I'm on vacation now (Chinese new year). I hope I'll find some time to revive my imx8 board. I've tried sandbox and qemu. Both of them are not reproducible. I'm wondering if it could be some packet loss that causes the issue. Because sandbox and qemu there won't be any missing packets because of loopback devices.

I have already wrote something but I can not test. Will send tonight. My
feeling is that sometime the initial sequence number of TCP ip is next to
wrap around but not sure.

And what happen if you are going to generate out of sequence packet
and with large seq_number on purpose?
I think that lwip has much more sense

Re: inconsistent wget behavior
Hi
Is this code correct?
if (tcp_seq_num >= initial_data_seq_num &&
store_block(pkt, tcp_seq_num - initial_data_seq_num,
len) != 0) {
wget_fail("wget: store error\n",
tcp_seq_num, tcp_ack_num, action);
return;
}
Can not be seq_num wrap around? Another point seems that is not
guarantee packet reassembly

Re: inconsistent wget behavior
Hi Fabio, I tried to investigate this by U-boot sandbox. But it seems to me that I cannot reproduce this issue. I put a file on localhost apache server and tried to download it from localhost. I might need a more persistent way to reproduce this bug.

The number of bytes transferred and md5sum always match, so this is a wget bug.

What if you take wget out of the equation and use "tftp" to grab a large file with a known checksum, repeatedly (note that "rhash -C" will give a crc32 in Linux so you can confirm the correct value and loop a get, crc32, compare, repeat loop with a little work) ? I ask because I was reminded today that for me at least, the RPi ethernet isn't reliable in U-Boot for me if you stress it too hard. So I'd like to try see if this is "wget bug" or "network driver/related bug". -- Tom signature.asc Description: PGP signature

inconsistent wget behavior
Greetings, I've recently given wget/tcp a try and find the results inconsistent. Transferring the same file 15 times in a row will eventually give me an incomplete transfer with packet/byte count wrong but showing 'Transfer Successful'.
