Subject: ABI Breakage - nftnl_rule_parse_attr_cb
Date: Tue, 21 Jun 2022 20:07:24 +0000	[thread overview]
Message-ID: <fb274774-b42e-fce8-7018-2c21a93a4d38@vt.edu> (raw)

Hi,

I am getting an ABI breakage error at these lines in rule.c:

case NFTA_RULE_HANDLE:
         if (mnl_attr_validate(attr, MNL_TYPE_U64) < 0)
             abi_breakage();
         break;

It only seems to happen when I set the flag NLM_F_ECHO in 
nftnl_rule_nlmsg_build_hdr. I want to hold onto the rule handle of the 
returned rule, which is why I set it to echo. This error was not 
affecting me in Ubuntu 20.04, but started as soon as I upgraded to 
22.04. I am running Linux kernel version 5.15.0-39-generic with 
libnftnl-dev version 1.2.1-1build1.

Thanks,

Kiernan
