Package: linux
Version: 6.1.52-1
Severity: grave

Dear Maintainers,

linux-image-6.1.0-12-amd64 causes a serious regression in nftables. After 
upgrading one of my machines, nftables fails to start - leaving the system 
without an active firewall.

Doing
`nft -cf /etc/nftables.conf'
throws many "Operation not supported" errors on rulesets that have been in 
place for months wihtout issues.

Just to give two simple examples from the log when nftables fails to start:
/etc/nftables.conf:99:4-44: Error: Could not process rule: Operation not 
supported
                        tcp option maxseg size 1-500 counter drop
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/etc/nftables.conf:308:4-27: Error: Could not process rule: Operation not 
supported
                        tcp dport sip-tls accept
                        ^^^^^^^^^^^^^^^^^^^^^^^^

Downgrading to linux-image-6.1.0-11-amd64 resolves the issue.

Notes: I'm running a local rebuild of linux-image-amd64 with a few additional 
symbols enabled. But since these symbols are totally unrelated to the netfilter 
subsystem and there are no changes to the source itself, I'm certain, this 
affects the original Debian build as well. Whether it only affects certain 
architectures or rulesets, I can't say, though.

I'm cc'ing [email protected] because the update came via the 
stable-security channel.


Thanks and regards,

Timo
