Hello,
Since months I regular use a Netgear R7800 (hard drive connected in USB) to do transfers to and from using ssh (scp or sshfs).
But maybe since one or two months files get sometimes corrupted even if transfer is OK. The corruption frequency depends of computer used and file used, but with some files I don't have to make more than 5 transfers to see corruption.
used build : hnyman build (stable : 19.07 and recently 21.02, both impacted lately)
From the tests I have done, there are at least 2 working workaround :
Use dropbear (but slow)
Use hnyman master build (tested r17520) with openssh
So I suspect a problem with current SSH version. If this is the case :
If needed, the file I use to test is the source of nss-3.63.1 : nss-3.63.1.tar.gzhttp://ftp.luis.uni-hannover.de/gentoo/distfiles/11/nss-3.63.1.tar.gz )
I will do bug report for this if needed, but before would like to know if it can be reproduced and/or if I miss something.
Thank you.
ps : I'm new to openwrt, first post

Run a ip -s link to verify that there are no errors.

Back to 21.02 with openssh, sha256sum report corrupted file at first scp and it seems there are no errors :
