Such cases typically happen when there +is some sort of hierarchy within objects of the same type. In these +cases there is an inherent "natural" ordering between the two objects +(defined by the properties of the hierarchy), and the kernel grabs the +locks in this fixed order on each of the objects. + +An example of such an object hieararchy that results in "nested locking" +is that of a "whole disk" block-dev object and a "partition" block-dev +object; the partition is "part of" the whole device and as long as one +always takes the whole disk lock as a higher lock than the partition +lock, the lock ordering is fully correct. The validator does not +automatically detect this natural ordering, as the locking rule behind +the ordering is not static. + +In order to teach the validator about this correct usage model, new +versions of the various locking primitives were added that allow you to +specify a "nesting level". An example call, for the block device mutex, +looks like this: + +enum bdev_bd_mutex_lock_class +{ + BD_MUTEX_NORMAL, + BD_MUTEX_WHOLE, + BD_MUTEX_PARTITION +}; + + mutex_lock_nested(&bdev->bd_contains->bd_mutex, BD_MUTEX_PARTITION); + +In this case the locking is done on a bdev object that is known to be a +partition. + +The validator treats a lock that is taken in such a nested fasion as a +separate (sub)class for the purposes of validation. + +Note: When changing code to use the _nested() primitives, be careful and +check really thoroughly that the hiearchy is correctly mapped; otherwise +you can get false positives or false negatives. + +Proof of 100% correctness: +-------------------------- + +The validator achieves perfect, mathematical 'closure' (proof of locking +correctness) in the sense that for every simple, standalone single-task +locking sequence that occured at least once during the lifetime of the +kernel, the validator proves it with a 100% certainty that no +combination and timing of these locking sequences can cause any class of +lock related deadlock. [*] + +I.e. complex multi-CPU and multi-task locking scenarios do not have to +occur in practice to prove a deadlock: only the simple 'component' +locking chains have to occur at least once (anytime, in any +task/context) for the validator to be able to prove correctness. (For +example, complex deadlocks that would normally need more than 3 CPUs and +a very unlikely constellation of tasks, irq-contexts and timings to +occur, can be detected on a plain, lightly loaded single-CPU system as +well!) + +This radically decreases the complexity of locking related QA of the +kernel: what has to be done during QA is to trigger as many "simple" +single-task locking dependencies in the kernel as possible, at least +once, to prove locking correctness - instead of having to trigger every +possible combination of locking interaction between CPUs, combined with +every possible hardirq and softirq nesting scenario (which is impossible +to do in practice). + +[*] assuming that the validator itself is 100% correct, and no other + part of the system corrupts the state of the validator in any way. + We also assume that all NMI/SMM paths [which could interrupt + even hardirq-disabled codepaths] are correct and do not interfere + with the validator. We also assume that the 64-bit 'chain hash' + value is unique for every lock-chain in the system. Also, lock + recursion must not be higher than 20. + +Performance: +------------ + +The above rules require _massive_ amounts of runtime checking. If we did +that for every lock taken and for every irqs-enable event, it would +render the system practically unusably slow. The complexity of checking +is O(N^2), so even with just a few hundred lock-classes we'd have to do +tens of thousands of checks for every event. + +This problem is solved by checking any given 'locking scenario' (unique +sequence of locks taken after each other) only once. A simple stack of +held locks is maintained, and a lightweight 64-bit hash value is +calculated, which hash is unique for every lock chain. The hash value, +when the chain is validated for the first time, is then put into a hash +table, which hash-table can be checked in a lockfree manner. If the +locking chain occurs again later on, the hash table tells us that we +dont have to validate the chain again. diff --git a/trunk/Documentation/networking/ipvs-sysctl.txt b/trunk/Documentation/networking/ipvs-sysctl.txt new file mode 100644 index 000000000000..4ccdbca03811 --- /dev/null +++ b/trunk/Documentation/networking/ipvs-sysctl.txt @@ -0,0 +1,143 @@ +/proc/sys/net/ipv4/vs/* Variables: + +am_droprate - INTEGER + default 10 + + It sets the always mode drop rate, which is used in the mode 3 + of the drop_rate defense. + +amemthresh - INTEGER + default 1024 + + It sets the available memory threshold (in pages), which is + used in the automatic modes of defense.
