Subject: [PATCH net-2.6.25 0/10] Make fragments live in net namespaces
Date: Tue, 22 Jan 2008 16:52:36 +0300 [thread overview]
Message-ID: <4795F524.8060204@openvz.org> (raw)
The overall design I propose is to keep the hash table
global and tag inet_frag_queue with the net. Since the
fragments hash is going to be re-sizable, this is OK to
keep fragments from different namespace in one hash.
To speedup the evicting process LRU list is made per
namespace.
As far as the CTL-tuned variables are concerned, the
timeout and thresholds are made per namespace, since
they have the per namespace sense, but the secret rebuild
interval is read-only in sub-namespaces.
Since fragment management code is consolidated for ipv4
and ipv6 I make them all in one go. The conntrack_reasm
netns-ization is not done - we have to make at least the
core netfilter per namespace first, but this reasm code
is patched to keep working in the initial namespace.
