Subject: libxtables backward compatibility
Date: Sun, 3 Jul 2016 16:00:42 -0400 [thread overview]
Message-ID: <20160703160042.76f76433@playground> (raw)
I've search hither and yon and have found no (obvious) answers.
Are newer versions of libxtables.so backward-compatible with older versions?
Specifically, should programs linked to--and expecting to use--libxtables.so.7 (iptables v1.4.14) work with versions libxtables.so.10 (v1.4.21) and libxtables.so.11 (v1.6)? I suspect yes, since I haven't seen problems symlinking .10 to .7. But a definitive answer would be nice to have.
If they aren't compatible, I'll plan on including .7 and .10 binaries in the update packet.
(I know about nftables and look forward to deploying its flexibility, but we're still on linux 3.4; I'm working on updating to 3.14. Our next release will use linux 4.4 (or newer) and nftables. But that is a major change; we have a lot of rule generators in several syntaxes that will need to be modernized. The user interface will also need to be reworked.)
Thanks,
Neal
