Patch to imlement plugins
Thanks for patch, I'll append it, but it could be earliest in fedora core 7.
Many thanks. If you do so, I will suggest to create a package vsftpd-devel with
the following files:
to allow easy plugin development.
... by looking at the development packages, it seems it will NOT be included in
Fedora 7 ...
Are there some plans to really include it ?
Hi, sorry but this plugins could be implemented in Fedora 9 and later after
testing version. Upstream doesn't answer a long time so we have to make review,
test package and a lot of tests. Sorry for this long process.
Yes, upstream site seems abandoned. This is a pity because the product is good.
I hope I'm wrong, ot that someone else will make it live again.
Anyway, I'm running FC6 for now and ported this patch to the FC6 version (2.0.5-
10): I'm using it daily (in a prod server) and it did not need real update
since FC6 early days.
When you need the patch for 2.0.5-10, just ask here !
Thanks for your interest
Will functions that are called using this plugin be able to access files out of the chroot? (e.g. /bin/sh )
No. They are called directly. Plugin library is loaded dynamically (dlopen), plugin function addresses are latched, then called when needed, thus being executed in the same context as the server process. No fork/exec is performed.

Patch to implement plugins (against vsftpd-2.2.0-5)
This version of the patch fixes compilation problems on 64-bit architectures
Upstream communicates over one year again. I've sent the patch to Chris Evans aprox. half a year ago. I don't plan to add this patch independently of upstream.
Upstream has obtained this patch therefore I don't see any reason to keep the bug opened in accordance to comment 11.
