general/other Linuxulator and mqueuefs

[qubu88]

Hello all,

I am having a problem opening the fedora binary on FreeBSD in Linux compatibility mode. It looks like mqueuefs is not working/implemented in compatibility mode. Can anyone confirm this?
Simple test binary which uses mq_open function does not work. Output from dmesg:

linux: jid 0 pid 9053 (test_mq_linux): syscall mq_open not implemented

Thanks
Kuba

according to https://cgit.freebsd.org/src/tree/sys/compat/linux/linux_dummy.c there is no such thing, so I guess you are right and it has not been implemented

FreeBSD seems to have an mqueuefs: https://man.freebsd.org/cgi/man.cgi?query=mqueuefs

But it doesn't have a layer to provide a Linux variant. So the next step is figuring out what the differences are between that fs in Linux and in FreeBSD. Maybe only a thin layer is needed.
