IPVS: Move IPVS to net/netfilter/ipvs

2008-10-06T21:38:24Z

Since IPVS now has partial IPv6 support, this patch moves IPVS from net/ipv4/ipvs to net/netfilter/ipvs. It's a result of: $ git mv net/ipv4/ipvs net/netfilter and adapting the relevant Kconfigs/Makefiles to the new path. Signed-off-by: Julius Volz Signed-off-by: Simon Horman

ipvs: Restrict sync message to 255 connections

2008-09-21T23:55:58Z

The nr_conns variable in the sync message header is only eight bits wide and will overflow on interfaces with a large MTU. As a result the backup won't parse all connections contained in the sync buffer. On regular ethernet with an MTU of 1500 this isn't a problem, because we can't overflow the value, but consider jumbo frames being used on a cross-over connection between both directors. We now restrict the size of the sync buffer, so that we never put more than 255 connections into a single sync buffer. Signed-off-by: Sven Wegener Signed-off-by: Simon Horman

ipvs: Use pointer to address from sync message

2008-09-07T23:34:43Z

We want a pointer to it, not the value casted to a pointer. Signed-off-by: Sven Wegener Acked-by: Julius Volz Signed-off-by: Simon Horman

IPVS: Convert real server lookup functions

2008-09-05T01:17:10Z

Convert functions for looking up destinations (real servers) to support IPv6 services/dests. Signed-off-by: Julius Volz Signed-off-by: Simon Horman

IPVS: Extend functions for getting/creating connections

2008-09-05T01:17:08Z

Extend functions for getting/creating connections and connection templates for IPv6 support and fix the callers. Signed-off-by: Julius Volz Signed-off-by: Simon Horman

IPVS: Change IPVS data structures to support IPv6 addresses

2008-09-05T01:17:03Z

Introduce new 'af' fields into IPVS data structures for specifying an entry's address family. Convert IP addresses to be of type union nf_inet_addr. Signed-off-by: Julius Volz Signed-off-by: Simon Horman

ipvs: Fix possible deadlock in sync code

2008-08-11T09:44:38Z

Commit 998e7a76804b7a273a0460c2cdd5a51fa9856717 ("ipvs: Use kthread_run() instead of doing a double-fork via kernel_thread()") introduced a possible deadlock in the sync code. We need to use the _bh versions for the lock, as the lock is also accessed from a bottom half. Signed-off-by: Sven Wegener Acked-by: Simon Horman

ipvs: Use schedule_timeout_interruptible() instead of msleep_interruptible()

2008-07-16T22:33:20Z

So that kthread_stop() can wake up the thread and we don't have to wait one second in the worst case for the daemon to actually stop. Signed-off-by: Sven Wegener Acked-by: Simon Horman

ipvs: Put backup thread on mcast socket wait queue

2008-07-16T22:33:20Z

Instead of doing an endless loop with sleeping for one second, we now put the backup thread onto the mcast socket wait queue and it gets woken up as soon as we have data to process. Signed-off-by: Sven Wegener Acked-by: Simon Horman

ipvs: Use kthread_run() instead of doing a double-fork via kernel_thread()

2008-07-16T22:33:20Z

This also moves the setup code out of the daemons, so that we're able to return proper error codes to user space. The current code will return success to user space when the daemon is started with an invald mcast interface. With these changes we get an appropriate "No such device" error. We longer need our own completion to be sure the daemons are actually running, because they no longer contain code that can fail and kthread_run() takes care of the rest.
