[IPVS]: Synchronize closing of Connections

2007-11-07T12:15:10+00:00

This patch makes the master daemon to sync the connection when it is about
to close.  This makes the connections on the backup to close or timeout
according their state.  Before the sync was performed only if the
connection is in ESTABLISHED state which always made the connections to
timeout in the hard coded 3 minutes. However the Andy Gospodarek's patch
([IPVS]: use proper timeout instead of fixed value) effectively did nothing
more than increasing this to 15 minutes (Established state timeout).  So
this patch makes use of proper timeout since it syncs the connections on
status changes to FIN_WAIT (2min timeout) and CLOSE (10sec timeout).
However if the backup misses CLOSE hopefully it did not miss FIN_WAIT.
Otherwise we will just have to wait for the ESTABLISHED state timeout. As
it is without this patch.  This way the number of the hanging connections
on the backup is kept to minimum. And very few of them will be left to
timeout with a long timeout.

This is important if we want to make use of the fix for the real server
overcommit on master/backup fail-over.

[NETFILTER]: Replace sk_buff ** with sk_buff *

2007-10-15T19:26:29+00:00

With all the users of the double pointers removed, this patch mops up by
finally replacing all occurances of sk_buff ** in the netfilter API by
sk_buff *.

[IPVS]: Replace local version of skb_make_writable

This patch removes the IPVS-specific version of skb_make_writable and
replaces it with the netfilter one.

[IPV4]: Change ip_defrag to return an integer

2007-10-15T19:26:25+00:00

Now that ip_frag always returns the packet given to it on input, we can
change it to return an integer indicating error instead.  This patch does
that and updates all its callers accordingly.

[IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_dev

2007-10-10T23:52:48+00:00

Now that multiple loopback devices are becoming possible it makes
the code a little cleaner and more maintainable to test if a deivice
is th a loopback device by testing dev->flags & IFF_LOOPBACK instead
of dev == loopback_dev.

[NET]: Dynamically allocate the loopback device, part 1.

2007-10-10T23:52:14+00:00

This patch replaces all occurences to the static variable
loopback_dev to a pointer loopback_dev. That provides the
mindless, trivial, uninteressting change part for the dynamic
allocation for the loopback.

[NET]: Treat CHECKSUM_PARTIAL as CHECKSUM_UNNECESSARY

2007-04-26T05:28:43+00:00

When a transmitted packet is looped back directly, CHECKSUM_PARTIAL
maps to the semantics of CHECKSUM_UNNECESSARY.  Therefore we should
treat it as such in the stack.

[IP]: Introduce ip_hdrlen()

2007-04-26T05:25:07+00:00

For the common sequence "skb->nh.iph->ihl * 4", removing a good number of open
coded skb->nh.iph uses, now to go after the rest...

Just out of curiosity, here are the idioms found to get the same result:

skb->nh.iph->ihl << 2
skb->nh.iph->ihl<<2
skb->nh.iph->ihl * 4
skb->nh.iph->ihl*4
(skb->nh.iph)->ihl * sizeof(u32)
