seccomp is activated by default in vsftpd and this has caused compatibility issues with some kernel versions. This was fixed as one can see as https://bugzilla.redhat.com/show_bug.cgi?id=845980, but can still cause issues with newer kernels with kernel 4.18+. And there is even a patch 0034-Turn-off-seccomp-sandbox-because-it-is-too-strict.patch in fedora[https://dl.fedoraproject.org/pub/fedora/linux/releases/29/Everything/source/tree/Packages/v/vsftpd-3.0.3-28.fc29.src.rpm] turning off seccomp sandbox for vsftpd by default as below which means fedora doesn't limit the syscall any more by default. [snip] - tunable_seccomp_sandbox = 1; + tunable_seccomp_sandbox = 0; tunable_allow_writeable_chroot = 0; tunable_accept_timeout = 60; [snip] Refresh 0001-vsftpd-allow-sysinfo-in-the-seccomp-sandbox.patch to allow one more syscall getdents64 in the seccomp sandbox apart from the previous one in below commit: fbffcf3f3 vsftpd: allow sysinfo() in the seccomp sandbox before this patch: root@qemux86-64:~# tnftp 127.0.0.1 Connected to 127.0.0.1. 220 (vsFTPd 3.0.3) Name (127.0.0.1:root): anonymous 331 Please specify the password.

meta-networking
===============
This layer is intended to be a central point for networking-related
packages and configuration. It should be useful directly on top of
oe-core and compliments meta-openembedded. It should be primarily useful
to the following groups:
- Anyone building a small networking device (eg. a home router /
bridge / switch).
- Anyone wanting to add network services to their device (eg.
anything that might benefit from a small ftp/tftp server)
