* [NETLINK]: Generic netlink receive queue processorThomas Graf2005-11-09
| | | | | | | | | | | | | Introduces netlink_run_queue() to handle the receive queue of a netlink socket in a generic way. Processes as much as there was in the queue upon entry and invokes a callback function for each netlink message found. The callback function may refuse a message by returning a negative error code but setting the error pointer to 0 in which case netlink_run_queue() will return with a qlen != 0.

* [NETLINK]: Make netlink_callback->done() optionalThomas Graf2005-11-09
| | | | | | | | Most netlink families make no use of the done() callback, making it optional gets rid of all unnecessary dummy implementations. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETLINK]: Type-safe netlink messages/attributes interfaceThomas Graf2005-11-09
| | | | | | | | | | | | | | Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation. The resulting netlink code should be smaller, less error prone and easier to understand. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETFILTER]: Add nf_conntrack subsystem.Yasuyuki Kozakai2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing connection tracking subsystem in netfilter can only handle ipv4. There were basically two choices present to add connection tracking support for ipv6. We could either duplicate all of the ipv4 connection tracking code into an ipv6 counterpart, or (the choice taken by these patches) we could design a generic layer that could handle both ipv4 and ipv6 and thus requiring only one sub-protocol (TCP, UDP, etc.) connection tracking helper module to be written. In fact nf_conntrack is capable of working with any layer 3 protocol. The existing ipv4 specific conntrack code could also not deal with the pecularities of doing connection tracking on ipv6, which is also cured here. For example, these issues include: 1) ICMPv6 handling, which is used for neighbour discovery in ipv6 thus some messages such as these should not participate in connection tracking since effectively they are like ARP messages 2) fragmentation must be handled differently in ipv6, because the simplistic "defrag, connection track and NAT, refrag" (which the existing ipv4 connection tracking does) approach simply isn't feasible in ipv6 3) ipv6 extension header parsing must occur at the correct spots before and after connection tracking decisions, and there were no provisions for this in the existing connection tracking design 4) ipv6 has no need for stateful NAT The ipv4 specific conntrack layer is kept around, until all of the ipv4 specific conntrack helpers are ported over to nf_conntrack and it is feature complete. Once that occurs, the old conntrack stuff will get placed into the feature-removal-schedule and we will fully kill it off 6 months later.

* Fix AGP compile on non-x86 architecturesLinus Torvalds2005-11-09
| | | | | | | | | | | | AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i spurely an x86'ism. The proper AGP mapping flusher that should be used is "flush_agp_mappings()", which on x86 obviously happens to do a global TLB flush. This makes AGP (or at least the config _I_ happen to use) compile again on ppc64. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] i2c-viapro: Some adjustmentsJean Delvare2005-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The big i2c-viapro SMBus driver update which went into 2.6.14-git1 introduced a few minor issues. Nothing critical, but I would like a few adjustments to be merged in to fix the following problems: * VIA should not be spelled Via. * Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro driver. * When debugging is disabled, half of messages would be logged. * Drop an unneeded masking. * Some port reads can be avoided now that the transaction size is passed as a parameter to vt596_transaction(). * SMBus Receive Byte transactions are used for probing too (for EEPROMs), so hide errors on these too.

For small allocations this isn't really seen, but when you start allocating 50000 pages of AGP space, for say, texture memory, then things can take seconds to complete. In some cases the situation is doubled or even quadrupled in the time due to SMP, or a deallocation, then a new reallocation. I've had a case of upto 20 seconds wait time to deallocate and reallocate AGP space. This patch fixes the problem by making it the caller's responsibility to call global_flush_tlb(), and so removes it from every instance of mapping a page into AGP space until the time that all change_page_attr() changes are done.
