Hi, using the nfs-kernel-server package on openwrt x86_64 machine seems to throw a bug in the rpc.mountd: it crashes when a client try to make a remote mount.
I discovered a sort of bug by the combination of uclibc and nfs-utils. There is also a thread to this page that explain it https://bugs.alpinelinux.org/issues/1486. I tried to patch the code as suggested there and it works correctly! Please find attached a patch with the change. I made it against the trunk Hope to see it committed upstream.
