+IRQ-flags state tracing
+
+started by Ingo Molnar <mingo@redhat.com>
+
+the "irq-flags tracing" feature "traces" hardirq and softirq state, in
+that it gives interested subsystems an opportunity to be notified of
+every hardirqs-off/hardirqs-on, softirqs-off/softirqs-on event that
+happens in the kernel.
+
+CONFIG_TRACE_IRQFLAGS_SUPPORT is needed for CONFIG_PROVE_SPIN_LOCKING
+and CONFIG_PROVE_RW_LOCKING to be offered by the generic lock debugging
+code. Otherwise only CONFIG_PROVE_MUTEX_LOCKING and
+CONFIG_PROVE_RWSEM_LOCKING will be offered on an architecture - these
+are locking APIs that are not used in IRQ context. (the one exception
+for rwsems is worked around)
+
+architecture support for this is certainly not in the "trivial"
+category, because lots of lowlevel assembly code deal with irq-flags
+state changes. But an architecture can be irq-flags-tracing enabled in a
+rather straightforward and risk-free manner.
+
+Architectures that want to support this need to do a couple of
+code-organizational changes first:
+
+- move their irq-flags manipulation code from their asm/system.h header
+ to asm/irqflags.h
+
+- rename local_irq_disable()/etc to raw_local_irq_disable()/etc. so that
+ the linux/irqflags.h code can inject callbacks and can construct the
+ real local_irq_disable()/etc APIs.
+
+- add and enable TRACE_IRQFLAGS_SUPPORT in their arch level Kconfig file
+
+and then a couple of functional changes are needed as well to implement
+irq-flags-tracing support:
+
+- in lowlevel entry code add (build-conditional) calls to the
+ trace_hardirqs_off()/trace_hardirqs_on() functions. The lock validator
+ closely guards whether the 'real' irq-flags matches the 'virtual'
+ irq-flags state, and complains loudly (and turns itself off) if the
+ two do not match. Usually most of the time for arch support for
+ irq-flags-tracing is spent in this state: look at the lockdep
+ complaint, try to figure out the assembly code we did not cover yet,
+ fix and repeat. Once the system has booted up and works without a
+ lockdep complaint in the irq-flags-tracing functions arch support is
+ complete.
+- if the architecture has non-maskable interrupts then those need to be
+ excluded from the irq-tracing [and lock validation] mechanism via
+ lockdep_off()/lockdep_on().
+
+in general there is no risk from having an incomplete irq-flags-tracing
+implementation in an architecture: lockdep will detect that and will
+turn itself off. I.e. the lock validator will still be reliable. There
+should be no crashes due to irq-tracing bugs. (except if the assembly
+changes break other code by modifying conditions or registers that
+shouldnt be)

+Runtime locking correctness validator
+=====================================
+
+started by Ingo Molnar <mingo@redhat.com>
+additions by Arjan van de Ven <arjan@linux.intel.com>
+
+Lock-class
+----------
+
+The basic object the validator operates upon is a 'class' of locks.
+
+A class of locks is a group of locks that are logically the same with
+respect to locking rules, even if the locks may have multiple (possibly
+tens of thousands of) instantiations. For example a lock in the inode
+struct is one class, while each inode has its own instantiation of that
+lock class.
+
+The validator tracks the 'state' of lock-classes, and it tracks
+dependencies between different lock-classes. The validator maintains a
+rolling proof that the state and the dependencies are correct.
+
+Unlike an lock instantiation, the lock-class itself never goes away: when
+a lock-class is used for the first time after bootup it gets registered,
+and all subsequent uses of that lock-class will be attached to this
+lock-class.
+
+State
+-----
+
+The validator tracks lock-class usage history into 5 separate state bits:
+
+- 'ever held in hardirq context' [ == hardirq-safe ]
+- 'ever held in softirq context' [ == softirq-safe ]
+- 'ever held with hardirqs enabled' [ == hardirq-unsafe ]
+- 'ever held with softirqs and hardirqs enabled' [ == softirq-unsafe ]
+
+- 'ever used' [ == !unused ]
+
+Single-lock state rules:
+------------------------
+
+A softirq-unsafe lock-class is automatically hardirq-unsafe as well. The
+following states are exclusive, and only one of them is allowed to be
+set for any lock-class:
+
+ <hardirq-safe> and <hardirq-unsafe>
+ <softirq-safe> and <softirq-unsafe>
+
+The validator detects and reports lock usage that violate these
+single-lock state rules.
+
+Multi-lock dependency rules:
+----------------------------
+
+The same lock-class must not be acquired twice, because this could lead
+to lock recursion deadlocks.
+
+Furthermore, two locks may not be taken in different order:
+
+ <L1> -> <L2>
+ <L2> -> <L1>
+
+because this could lead to lock inversion deadlocks. (The validator
+finds such dependencies in arbitrary complexity, i.e. there can be any
+other locking sequence between the acquire-lock operations, the
+validator will still track all dependencies between locks.)
+
+Furthermore, the following usage based lock dependencies are not allowed
+between any two lock-classes:
+
+ <hardirq-safe> -> <hardirq-unsafe>
+ <softirq-safe> -> <softirq-unsafe>
+
+The first rule comes from the fact the a hardirq-safe lock could be
+taken by a hardirq context, interrupting a hardirq-unsafe lock - and
+thus could result in a lock inversion deadlock. Likewise, a softirq-safe
+lock could be taken by an softirq context, interrupting a softirq-unsafe
+lock.
+
+The above rules are enforced for any locking sequence that occurs in the
+kernel: when acquiring a new lock, the validator checks whether there is
+any rule violation between the new lock and any of the held locks.
+
+When a lock-class changes its state, the following aspects of the above
+dependency rules are enforced:
+
+- if a new hardirq-safe lock is discovered, we check whether it
+ took any hardirq-unsafe lock in the past.
+
+- if a new softirq-safe lock is discovered, we check whether it took
+ any softirq-unsafe lock in the past.
+
+- if a new hardirq-unsafe lock is discovered, we check whether any
+ hardirq-safe lock took it in the past.
+
+- if a new softirq-unsafe lock is discovered, we check whether any
+ softirq-safe lock took it in the past.
+
+(Again, we do these checks too on the basis that an interrupt context
+could interrupt _any_ of the irq-unsafe or hardirq-unsafe locks, which
+could lead to a lock inversion deadlock - even if that lock scenario did
+not trigger in practice yet.)
+
+Exception: Nested data dependencies leading to nested locking
+-------------------------------------------------------------
+
+There are a few cases where the Linux kernel acquires more than one
+instance of the same lock-class. 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.
This sequence of events is committed to the memory coherence system in an order
that the rest of the system might perceive as the unordered set of { STORE A,
-STORE B, STORE C } all occuring before the unordered set of { STORE D, STORE E
+STORE B, STORE C } all occurring before the unordered set of { STORE D, STORE E

+

+
+amemthresh - INTEGER
+ default 1024
+
+ It sets the available memory threshold (in pages), which is
+ used in the automatic modes of defense. When there is no
+ enough available memory, the respective strategy will be
+ enabled and the variable is automatically set to 2, otherwise
+ the strategy is disabled and the variable is set to 1.
+
+cache_bypass - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ If it is enabled, forward packets to the original destination

+ address is not local (iph->daddr is RTN_UNICAST). It is mostly

+
+ Only available when IPVS is compiled with the CONFIG_IPVS_DEBUG
+
+ Higher debugging levels include the messages for lower debugging
+ levels, so setting debug level 2, includes level 0, 1 and 2
+ messages. Thus, logging becomes more and more verbose the higher
+ the level.
+
+drop_entry - INTEGER
+ 0 - disabled (default)
+
+ The drop_entry defense is to randomly drop entries in the
+ connection hash table, just in order to collect back some
+ memory for new connections. In the current code, the
+ drop_entry procedure can be activated every second, then it
+ randomly scans 1/32 of the whole and drops entries that are in
+ the SYN-RECV/SYNACK state, which should be effective against
+ syn-flooding attack.
+
+ The valid values of drop_entry are from 0 to 3, where 0 means
+ that this strategy is always disabled, 1 and 2 mean automatic
+ modes (when there is no enough available memory, the strategy
+ is enabled and the variable is automatically set to 2,
+ otherwise the strategy is disabled and the variable is set to
+ 1), and 3 means that that the strategy is always enabled.
+
+drop_packet - INTEGER
+ 0 - disabled (default)
+
+ The drop_packet defense is designed to drop 1/rate packets
+ before forwarding them to real servers. If the rate is 1, then
+ drop all the incoming packets.
+
+ The value definition is the same as that of the drop_entry. In
+ the automatic mode, the rate is determined by the follow
+ formula: rate = amemthresh / (amemthresh - available_memory)
+ when available memory is less than the available memory
+ threshold. When the mode 3 is set, the always mode drop rate
+ is controlled by the /proc/sys/net/ipv4/vs/am_droprate.
+
+expire_nodest_conn - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ The default value is 0, the load balancer will silently drop
+ packets when its destination server is not available. It may
+ be useful, when user-space monitoring program deletes the
+ destination server (because of server overload or wrong
+ detection) and add back the server later, and the connections
+ to the server can continue.
+
+ If this feature is enabled, the load balancer will expire the
+ connection immediately when a packet arrives and its
+ destination server is not available, then the client program
+ will be notified that the connection is closed. This is
+ equivalent to the feature some people requires to flush
+ connections when its destination is not available.
+
+expire_quiescent_template - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ When set to a non-zero value, the load balancer will expire
+ persistent templates when the destination server is quiescent.
+ This may be useful, when a user makes a destination server
+ quiescent by setting its weight to 0 and it is desired that
+ subsequent otherwise persistent connections are sent to a
+ different destination server. By default new persistent
+ connections are allowed to quiescent destination servers.
+
+ If this feature is enabled, the load balancer will expire the
+ persistence template if it is to be used to schedule a new
+ connection and the destination server is quiescent.
+
+nat_icmp_send - BOOLEAN
+ 0 - disabled (default)
+ not 0 - enabled
+
+ It controls sending icmp error messages (ICMP_DEST_UNREACH)
+ for VS/NAT when the load balancer receives packets from real
+ servers but the connection entries don't exist.
+
+secure_tcp - INTEGER
+ 0 - disabled (default)
+
+ The secure_tcp defense is to use a more complicated state
+ transition table and some possible short timeouts of each
+ state. In the VS/NAT, it delays the entering the ESTABLISHED
+ until the real server starts to send data and ACK packet
+ (after 3-way handshake).
+
+ The value definition is the same as that of drop_entry or
+ drop_packet.
+
+sync_threshold - INTEGER
+ default 3
+
+ It sets synchronization threshold, which is the minimum number
+ of incoming packets that a connection needs to receive before
+ the connection will be synchronized. A connection will be
+ synchronized, every time the number of its incoming packets
+ modulus 50 equals the threshold. The range of the threshold is
+ from 0 to 49.

-The time allowed for off node allocations after zone reclaim
-has failed to reclaim enough pages to allow a local allocation.
+This is available only on NUMA kernels.
-Time is set in seconds and set by default to 30 seconds.
+A percentage of the file backed pages in each zone. Zone reclaim will only
+occur if more than this percentage of pages are file backed and unmapped.
+This is to insure that a minimal amount of local pages is still available for
+file I/O even if the node is overallocated.
-Reduce the interval if undesired off node allocations occur. However, too
-frequent scans will have a negative impact onoff node allocation performance.
+The default is 1 percent.

is a bit braindead (no matching channel masks or no matching filter mask),
we won't support this - yet. it doesn't event support negative filters,
so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
- parse TS data. USB bandwith will be a problem when having large
+ parse TS data. USB bandwidth will be a problem when having large

+ This feature enables the kernel to prove that all locking

+ correct: that under no circumstance could an arbitrary (and

+ sequences (on an arbitrary number of CPUs, running an
+ arbitrary number of tasks and interrupt contexts) cause a
+ deadlock.
+
+ In short, this feature enables the kernel to report locking
+ related deadlocks before they actually occur.
+
+ The proof does not depend on how hard and complex a
+ deadlock scenario would be to trigger: how many
+ participant CPUs, tasks and irq-contexts would be needed
+ for it to trigger. The proof also does not depend on
+ timing: if a race and a resulting deadlock is possible
+ theoretically (no matter how unlikely the race scenario
+ is), it will be proven so and will immediately be
+ reported by the kernel (once the event is observed that
+ makes the deadlock theoretically possible).
+
+ If a deadlock is impossible (i.e. the locking rules, as
+ observed by the kernel, are mathematically correct), the
+ kernel reports nothing.
+
+ NOTE: this feature can also be enabled for rwlocks, mutexes
+ and rwsems - in which case all dependencies between these
+ different locking variants are observed and mapped too, and
+ the proof of observed correctness is also maintained for an
+ arbitrary combination of these separate locking variants.
