[PATCH 6.1 027/798] netfilter: nf_tables: elements with timeout below CONFIG_HZ never expire

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>

[ Upstream commit e0c47281723f301894c14e6f5cd5884fdfb813f9 ]

Element timeout that is below CONFIG_HZ never expires because the
timeout extension is not allocated given that nf_msecs_to_jiffies64()
returns 0. Set timeout to the minimum value to honor timeout.

Fixes: 8e1102d5a159 ("netfilter: nf_tables: support timeouts larger than 23 days")
