Subject: meta time rules display after 00:00 UTC
Date: Tue, 31 Oct 2023 14:53:45 -0400 [thread overview]
Message-ID: <CAOoaxdFXq6aJJMrFC40PRqd7ZTJDroRVh-BpH8Vz7H618V5GYQ@mail.gmail.com> (raw)
meta hour rules don't display properly after being created when the
hour is on or after 00:00 UTC. The netlink debug looks correct for
seconds past midnight UTC, but displaying the rules looks like an
overflow or a byte order problem. I am in UTC-0400, so today, 20:00
and later exhibits the problem, while 19:00 and earlier hours are
fine.
nft add table ip t
nft add chain ip t c
nft add rule ip t c meta hour "19:00"-"19:59" counter
nft add rule ip t c meta hour "20:00"-"20:59" counter
nft list table ip t
table ip t {
chain c {
meta hour "19:00"-"19:59" counter packets 0 bytes 0
meta hour "1193042:28:16"-"1193043:27:16" counter
packets 0 bytes 0
}
}
# nft -d netlink -c add rule ip t c meta hour "20:00"-"20:59" counter

[ meta load hour => reg 1 ]
