Subject: [nf-next PATCH 0/2] netfilter: xt_recent: Allow for much larger hitcount values
Date: Thu, 13 Jun 2024 16:32:52 +0200 [thread overview]
Message-ID: <20240613143254.26622-1-phil@nwl.cc> (raw)
Patch 2 lifts the restriction of 255 as max hitcount value by adjusting
XT_RECENT_MAX_NSTAMPS value and increasing required struct field sizes
accordingly.
In struct recent_entry, field 'nstamps' was 16bit in size of unclear
reasons. Patch 1 changes that to match field 'index' providing rationale
why it is sufficient, thus pavin the way for keeping both at 32bit (and
avoiding a larger size for 'nstamps').
Phil Sutter (2):
netfilter: xt_reent: Reduce size of struct recent_entry::nstamps
netfilter: xt_recent: Largely lift restrictions on max hitcount value
