Re: handling rdma apps using chroot

I'm looking for ideas on the best way for handling applications which use

For background, I'm trying to run vsftpd over rsockets using the preload
library with fork support.  vsftpd will run only if I comment out its use of
chroot.  I can reproduce the issue by inserting a chroot call into rstream.

Does anyone have any suggestions?

Somehow you need to open the verbs device before doing the choot.. I
think once verbs is open there is no further need for sysfs and dev..

Sounds like you are chrooting before creating the listening socket?
