Add Netfilter hook functions or modify existing ones, if possible, to process IPv6 packets.

2008-09-05IPVS: Add 'af' args to protocol handler functionsJulius Volz4-118/+162
Add 'af' arguments to conn_schedule(), conn_in_get(), conn_out_get() and csum_check() function pointers in struct ip_vs_protocol. Extend the respective functions for TCP, UDP, AH and ESP and adjust the callers. The changes in the callers need to be somewhat extensive, since they now need to pass a filled out struct ip_vs_iphdr * to the modified functions instead of a struct iphdr *.

2008-09-05IPVS: Add IPv6 support flag to schedulersJulius Volz10-33/+63
Add 'supports_ipv6' flag to struct ip_vs_scheduler to indicate whether a scheduler supports IPv6. Set the flag to 1 in schedulers that work with IPv6, 0 otherwise. This flag is checked in a later patch while trying to add a service with a specific scheduler. Adjust debug in v6-supporting schedulers to work with both address families.

2008-09-05IPVS: Add internal versions of sockopt interface structsJulius Volz1-48/+90
Add extended internal versions of struct ip_vs_service_user and struct ip_vs_dest_user (the originals can't be modified as they are part of the old sockopt interface). Adjust ip_vs_ctl.c to work with the new data structures and add some minor AF-awareness. Signed-off-by: Julius Volz <[email protected]> Signed-off-by: Simon Horman <[email protected]>
2008-09-05IPVS: Change IPVS data structures to support IPv6 addressesJulius Volz18-108/+109

2008-09-02ipv: Re-enable IP when MTU > 68Breno Leitao1-3/+12
Re-enable IP when the MTU gets back to a valid size. This patch just checks if the in_dev is NULL on a NETDEV_CHANGEMTU event and if MTU is valid (bigger than 68), then re-enable in_dev. Also a function that checks valid MTU size was created. Signed-off-by: Breno Leitao <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2008-08-28tcp: Skip empty hash buckets faster in /proc/net/tcpAndi Kleen1-7/+19
On most systems most of the TCP established/time-wait hash buckets are empty. When walking the hash table for /proc/net/tcp their read locks would always be aquired just to find out they're empty. This patch changes the code to check first if the buckets have any entries before taking the lock, which is much cheaper than taking a lock. Since the hash tables are large this makes a measurable difference on processing /proc/net/tcp, especially on architectures with slow read_lock (e.g. PPC) On a 2GB Core2 system time cat /proc/net/tcp > /dev/null (with a mostly empty hash table) goes from 0.046s to 0.005s. On systems with slower atomics (like P4 or POWER4) or larger hash tables (more RAM) the difference is much higher. This can be noticeable because there are some daemons around who regularly scan /proc/net/tcp. Original idea for this patch from Marcus Meissner, but redone by me.

2008-08-19ipvs: Fix race conditions in lblcr schedulerSven Wegener1-115/+114
We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. Also getting an entry under read lock, then locking for write and trying to delete that entry looks fishy, but should be no problem here, because we're only comparing a pointer. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.

2008-08-19ipvs: Fix race conditions in lblc schedulerSven Wegener1-108/+96
We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. And we also need to check in the critical region wether the destination is still available, i.e. it's not in the trash. If we drop our reference counter, the destination can be purged from the trash at any time. Our caller only guarantees that no destination is moved to the trash, while we are scheduling. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.

2008-08-15ipv4: Disable route secret interval on zero intervalHerbert Xu1-6/+70
Let me first state that disabling the route cache hash rebuild should not be done without extensive analysis on the risk profile and careful deliberation. However, there are times when this can be done safely or for testing. For example, when you have mechanisms for ensuring that offending parties do not exist in your network. This patch lets the user disable the rebuild if the interval is set to zero. This also incidentally fixes a divide-by-zero error with name-spaces. In addition, this patch makes the effect of an interval change immediate rather than it taking effect at the next rebuild as is currently the case.

Commit 8ab19ea36c5c5340ff598e4d15fc084eb65671dc ("ipvs: Fix possible deadlock in estimator code") fixed a deadlock condition, but that condition can only happen during unload of IPVS, because during normal operation there is at least our global stats structure in the estimator list. The mod_timer() and del_timer_sync() calls are actually initialization and cleanup code in disguise. Let's make it explicit and move them to their own init and cleanup function.

2008-08-15ipvs: Only call init_service, update_service and done_service for schedulers ↵Sven Wegener8-123/+12
if defined There are schedulers that only schedule based on data available in the service or destination structures and they don't need any persistent storage or initialization routine. These schedulers currently provide dummy functions for the init_service, update_service and/or done_service functions.

2008-08-11ipvs: Explictly clear ip_vs_stats membersSimon Horman1-1/+14
In order to align the coding styles of ip_vs_zero_stats() and its child-function ip_vs_zero_estimator(), clear ip_vs_stats members explicitlty rather than doing a limited memset(). This was chosen over modifying ip_vs_zero_estimator() to use memset() as it is more robust against changes in members in the relevant structures. memset() would be prefered if all members of the structure were to be cleared.

2008-08-11ipvs: No need to zero out ip_vs_stats during initializationSven Wegener1-3/+3
It's a global variable and automatically initialized to zero. And now we can also initialize the lock at compile time. Signed-off-by: Sven Wegener <[email protected]> Acked-by: Simon Horman <[email protected]>
2008-08-11ipvs: Embed estimator object into stats objectSven Wegener2-80/+39
There's no reason for dynamically allocating an estimator object for every stats object. Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

2008-08-11ipvs: Annotate init functions with __initSven Wegener4-5/+5
Being able to discard these functions saves a couple of bytes at runtime. The cleanup functions can't be annotated with __exit as they are also called from init functions. Signed-off-by: Sven Wegener <[email protected]> Acked-by: Simon Horman <[email protected]>
