/*
* Queue Management APIs
*
* There are currently two subtly different methods of maintining
* a queue of objects. Both APIs are contained in this file, and
* unfortunately overlap.
* (there is also a third way maintained in bsd/sys/queue.h)
*
* Both methods use a common queue head and linkage pattern:
* The head of a queue is declared as:
* queue_head_t q_head;
*
* Elements in this queue are chained together using
* struct queue_entry objects embedded within a structure:
* struct some_data {
* int field1;
* int field2;
* ...
* queue_chain_t link;
* ...
* int last_field;
* };
* struct some_data is referred to as the queue "element."
* (note that queue_chain_t is typedef'd to struct queue_entry)
*
* IMPORTANT: The two queue iteration methods described below are not
* compatible with one another. You must choose one and be careful
* to use only the supported APIs for that method.
*
* Method 1: chaining of queue_chain_t (linkage chains)
* This method uses the next and prev pointers of the struct queue_entry
* linkage object embedded in a queue element to point to the next or
* previous queue_entry structure in the chain. The head of the queue
* (the queue_head_t object) will point to the first and last
* struct queue_entry object, and both the next and prev pointer will
* point back to the head if the queue is empty.
*
* This method is the most flexible method of chaining objects together
* as it allows multiple chains through a given object, by embedding
* multiple queue_chain_t objects in the structure, while simultaneously
* providing fast removal and insertion into the queue using only
* struct queue_entry object pointers.
*

* [1] qe_foreach_element
* [1] qe_foreach_element_safe
*
* Method 2: chaining of elements (element chains)
* This method uses the next and prev pointers of the struct queue_entry
* linkage object embedded in a queue element to point to the next or
* previous queue element (not another queue_entry). The head of the
* queue will point to the first and last queue element (struct some_data
* from the above example) NOT the embedded queue_entry structure. The
* first queue element will have a prev pointer that points to the
* queue_head_t, and the last queue element will have a next pointer
* that points to the queue_head_t.
*
* This method requires knowledge of the queue_head_t of the queue on
* which an element resides in order to remove the element. Iterating
* through the elements of the queue is also more cumbersome because
* a check against the head pointer plus a cast then offset operation
* must be performed at each step of the iteration.

* A generic priorty ordered queue implementation based on pairing heaps.
*
* Reference Papers:
* - A Back-to-Basics Empirical Study of Priority Queues (https://arxiv.org/abs/1403.0252)
* - The Pairing Heap: A New Form of Self-Adjusting Heap
* (https://www.cs.cmu.edu/~sleator/papers/pairing-heaps.pdf)
*
* The XNU implementation is a basic version of the pairing heap.
* It allows for O(1) insertion and amortized O(log n) deletion.
*
* It is not a stable data structure by default since adding stability would
* need more pointers and hence more memory.
*
* Type of queues
*
* There are several types of priority queues, with types named:
*
* struct priority_queue_<subtype>_<min|max>
*
* In the rest of this header, `struct priority_queue` is used as
* a generic type to mean any priority_queue type.
*
* min/max refers to whether the priority queue is a min or a max heap.
*
* the subtype can be:
*
* - sched, in which case the key is built in the linkage and assumed to
* be a scheduler priority.
*
* - sched_stable, in which case the key is a combination of:
* * a scheduler priority
* * whether the entry was preempted or not
* * a timestamp.
*
* - generic, in which case a comparison function must be passed to
* the priority_queue_init.
*
* Element Linkage:
*
* Both types use a common queue head and linkage pattern.
* The head of a priority queue is declared as:
*
* struct priority_queue_<subtype>_<min|max> pq_head;
*
* Elements in this queue are linked together using one of the struct
* priority_queue_entry_<subtype> objects embedded within a structure:
*
* struct some_data {
* int field1;
* int field2;
* ...
* struct priority_queue_entry link;
* ...
* int last_field;
* };
* struct some_data is referred to as the queue "element"
*
* This method uses the next, prev and child pointers of the struct
* priority_queue_entry linkage object embedded in a queue element to
* point to other elements in the queue. The head of the priority queue
* (the priority_queue object) will point to the root of the pairing
* heap (NULL if heap is empty). This method allows multiple chains
* through a given object, by embedding multiple priority_queue_entry
* objects in the structure, while simultaneously providing fast removal
* and insertion into the heap using only priority_queue_entry object
* pointers.

/*
*
* THE KCDATA MANIFESTO
*
* Kcdata is a self-describing data serialization format. It is meant to get
* nested data structures out of xnu with minimum fuss, but also for that data
* to be easy to parse. It is also meant to allow us to add new fields and
* evolve the data format without breaking old parsers.
*
* Kcdata is a permanent data format suitable for long-term storage including
* in files. It is very important that we continue to be able to parse old
* versions of kcdata-based formats. To this end, there are several
* invariants you MUST MAINTAIN if you alter this file.
*
* * None of the magic numbers should ever be a byteswap of themselves or
* of any of the other magic numbers.
*
* * Never remove any type.
*
* * All kcdata structs must be packed, and must exclusively use fixed-size
* types.
*
* * Never change the definition of any type, except to add new fields to
* the end.
*
* * If you do add new fields to the end of a type, do not actually change
* the definition of the old structure. Instead, define a new structure
* with the new fields. See thread_snapshot_v3 as an example. This
* provides source compatibility for old readers, and also documents where
* the potential size cutoffs are.
*
* * If you change libkdd, or kcdata.py run the unit tests under libkdd.
*
* * If you add a type or extend an existing one, add a sample test to
* libkdd/tests so future changes to libkdd will always parse your struct
* correctly.
*
* For example to add a field to this:
*
* struct foobar {
* uint32_t baz;
* uint32_t quux;
* } __attribute__ ((packed));
*
* Make it look like this:
*
* struct foobar {
* uint32_t baz;
* uint32_t quux;
* ///////// end version 1 of foobar. sizeof(struct foobar) was 8 ////////
* uint32_t frozzle;
* } __attribute__ ((packed));
*
* If you are parsing kcdata formats, you MUST
*
* * Check the length field of each struct, including array elements. If the
* struct is longer than you expect, you must ignore the extra data.
*
* * Ignore any data types you do not understand.
*
* Additionally, we want to be as forward compatible as we can. Meaning old
* tools should still be able to use new data whenever possible. To this end,
* you should:
*
* * Try not to add new versions of types that supplant old ones. Instead
* extend the length of existing types or add supplemental types.
*
* * Try not to remove information from existing kcdata formats, unless
* removal was explicitly asked for. For example it is fine to add a
* stackshot flag to remove unwanted information, but you should not
* remove it from the default stackshot if the new flag is absent.
*
* * (TBD) If you do break old readers by removing information or
* supplanting old structs, then increase the major version number.
*
*
*
* The following is a description of the kcdata format.
*
*
* The format for data is setup in a generic format as follows
*
* Layout of data structure:
*
* | 8 - bytes |
* | type = MAGIC | LENGTH |
* | 0 |
* | type | size |
* | flags |
* | data |
* |___________data____________|
* | type | size |
* | flags |
* |___________data____________|
* | type = END | size=0 |
* | 0 |
*
*
* The type field describes what kind of data is passed. For example type = TASK_CRASHINFO_UUID means the following data is a uuid.
* These types need to be defined in task_corpses.h for easy consumption by userspace inspection tools.
*
* Some range of types is reserved for special types like ints, longs etc. A cool new functionality made possible with this
* extensible data format is that kernel can decide to put more information as required without requiring user space tools to
* re-compile to be compatible. The case of rusage struct versions could be introduced without breaking existing tools.
*
* Feature description: Generic data with description
* -------------------
* Further more generic data with description is very much possible now. For example
*
* - kcdata_add_uint64_with_description(cdatainfo, 0x700, "NUM MACH PORTS");
* - and more functions that allow adding description.
* The userspace tools can then look at the description and print the data even if they are not compiled with knowledge of the field apriori.
*
* Example data:
* 0000 57 f1 ad de 00 00 00 00 00 00 00 00 00 00 00 00 W...............
* 0010 01 00 00 00 00 00 00 00 30 00 00 00 00 00 00 00 ........0.......
* 0020 50 49 44 00 00 00 00 00 00 00 00 00 00 00 00 00 PID.............

* 0090 ed 58 91 f1
*
* Feature description: Container markers for compound data
* ------------------
* If a given kernel data type is complex and requires adding multiple optional fields inside a container
* object for a consumer to understand arbitrary data, we package it using container markers.
*
* For example, the stackshot code gathers information and describes the state of a given task with respect
* to many subsystems. It includes data such as io stats, vm counters, process names/flags and syscall counts.
*
* kcdata_add_container_marker(kcdata_p, KCDATA_TYPE_CONTAINER_BEGIN, STACKSHOT_KCCONTAINER_TASK, task_uniqueid);
* // add multiple data, or add_<type>_with_description()s here
*
* kcdata_add_container_marker(kcdata_p, KCDATA_TYPE_CONTAINER_END, STACKSHOT_KCCONTAINER_TASK, task_uniqueid);
*
* Feature description: Custom Data formats on demand
* --------------------
* With the self describing nature of format, the kernel provider can describe a data type (uniquely identified by a number) and use
* it in the buffer for sending data. The consumer can parse the type information and have knowledge of describing incoming data.
* Following is an example of how we can describe a kernel specific struct sample_disk_io_stats in buffer.
*
* struct sample_disk_io_stats {
* uint64_t disk_reads_count;
* uint64_t disk_reads_size;
* uint64_t io_priority_count[4];
* uint64_t io_priority_size;
* } __attribute__ ((packed));
*
*
* struct kcdata_subtype_descriptor disk_io_stats_def[] = {
* {KCS_SUBTYPE_FLAGS_NONE, KC_ST_UINT64, 0 * sizeof(uint64_t), sizeof(uint64_t), "disk_reads_count"},
* {KCS_SUBTYPE_FLAGS_NONE, KC_ST_UINT64, 1 * sizeof(uint64_t), sizeof(uint64_t), "disk_reads_size"},
* {KCS_SUBTYPE_FLAGS_ARRAY, KC_ST_UINT64, 2 * sizeof(uint64_t), KCS_SUBTYPE_PACK_SIZE(4, sizeof(uint64_t)), "io_priority_count"},
* {KCS_SUBTYPE_FLAGS_ARRAY, KC_ST_UINT64, (2 + 4) * sizeof(uint64_t), sizeof(uint64_t), "io_priority_size"},
* };
*
* Now you can add this custom type definition into the buffer as
* kcdata_add_type_definition(kcdata_p, KCTYPE_SAMPLE_DISK_IO_STATS, "sample_disk_io_stats",
* &disk_io_stats_def[0], sizeof(disk_io_stats_def)/sizeof(struct kcdata_subtype_descriptor));
*
* Feature description: Compression
* --------------------
* In order to avoid keeping large amunt of memory reserved for a panic stackshot, kcdata has support
* for compressing the buffer in a streaming fashion. New data pushed to the kcdata buffer will be
* automatically compressed using an algorithm selected by the API user (currently, we only support
* pass-through and zlib, in the future we plan to add WKDM support, see: 57913859).
*
* To start using compression, call:
* kcdata_init_compress(kcdata_p, hdr_tag, memcpy_f, comp_type);
* where:
* `kcdata_p` is the kcdata buffer that will be used
* `hdr_tag` is the usual header tag denoting what type of kcdata buffer this will be
* `memcpy_f` a memcpy(3) function to use to copy into the buffer, optional.
* `compy_type` is the compression type, see KCDCT_ZLIB for an example.
*
* Once compression is initialized:
* (1) all self-describing APIs will automatically compress
* (2) you can now use the following APIs to compress data into the buffer:
* (None of the following will compress unless kcdata_init_compress() has been called)
*
* - kcdata_push_data(kcdata_descriptor_t data, uint32_t type, uint32_t size, const void *input_data)
* Pushes the buffer of kctype @type at[@input_data, @input_data + @size]
* into the kcdata buffer @data, compressing if needed.
*
* - kcdata_push_array(kcdata_descriptor_t data, uint32_t type_of_element,
* uint32_t size_of_element, uint32_t count, const void *input_data)
* Pushes the array found at @input_data, with element type @type_of_element, where
* each element is of size @size_of_element and there are @count elements into the kcdata buffer
* at @data.
*
* - kcdata_compression_window_open/close(kcdata_descriptor_t data)
* In case the data you are trying to push to the kcdata buffer @data is difficult to predict,
* you can open a "compression window". Between an open and a close, no compression will be done.
* Once you clsoe the window, the underlying compression algorithm will compress the data into the buffer
* and automatically rewind the current end marker of the kcdata buffer.
* There is an ASCII art in kern_cdata.c to aid the reader in understanding
* this.
*
* - kcdata_finish_compression(kcdata_descriptor_t data)
* Must be called at the end to flush any underlying buffers used by the compression algorithms.
* This function will also add some statistics about the compression to the buffer which helps with
* decompressing later.
*
* Once you are done with the kcdata buffer, call kcdata_deinit_compress to
* free any buffers that may have been allocated internal to the compression
* algorithm.

* Interruptible flag for waits.
*
* THREAD_UNINT: Uninterruptible wait
* Wait will only end when someone explicitly wakes up the thread, or if the
* wait timeout expires.
*
* Use this state if the system as a whole cannot recover from a thread being
* interrupted out of the wait.
*
* THREAD_INTERRUPTIBLE:
* Wait will end if someone explicitly wakes up the thread, the wait timeout
* expires, or the current thread is being terminated.
*
* This value can be used when your operation may not be cleanly restartable
* for the current process or thread (i.e. the loss of state would be only visible
* to the current client). Since the thread is exiting anyways, you're willing
* to cut the operation short. The system as a whole must be able to cleanly
* deal with the interruption (i.e. remain in a consistent and recoverable state).
*
* THREAD_ABORTSAFE:
* Wait will end if someone explicitly wakes up the thread, the wait timeout
* expires, the current thread is being terminated, if any signal arrives for
* the task, or thread_abort_safely() is called on the thread.
*
* Using this value means that you are willing to be interrupted in the face
* of any user signal, and safely rewind the thread back to the user/kernel
* boundary. Many syscalls will try to restart the operation they were performing
* after the signal has been handled.
*
* You must provide this value for any unbounded wait - otherwise you will
* pend user signals forever.
*
* THREAD_WAIT_NOREPORT:
* The scheduler has a callback (sched_call) that some subsystems use to
* decide whether more threads should be thrown at a given problem by trying
* to maintain a good level of concurrency.
*
* When the wait will not be helped by adding more threads (e.g. lock
* contention), using this flag as an argument to assert_wait* (or any of its
* wrappers) will prevent the next wait/block to cause thread creation.
*
* This comes in two flavors: THREAD_WAIT_NOREPORT_KERNEL, and
* THREAD_WAIT_NOREPORT_USER to prevent reporting about the wait for kernel
* and user threads respectively.
*
* Thread interrupt mask:
*
* The current maximum interruptible state for the thread, as set by
* thread_interrupt_level(), will limit the conditions that will cause a wake.
* This is useful for code that can't be interrupted to set before calling code
* that doesn't know that.
*
* Thread termination vs safe abort:
*
* Termination abort: thread_abort(), thread_terminate()
*
* A termination abort is sticky. Once a thread is marked for termination, every
* THREAD_INTERRUPTIBLE wait will return immediately with THREAD_INTERRUPTED
* until the thread successfully exits.
*
* Safe abort: thread_abort_safely()
*
* A safe abort is not sticky. The current wait, (or the next wait if the thread
* is not currently waiting) will be interrupted, but then the abort condition is cleared.
* The next wait will sleep as normal. Safe aborts only have a single effect.
*
* The path back to the user/kernel boundary must not make any further unbounded
* wait calls. The waiter should detect the THREAD_INTERRUPTED return code
* from an ABORTSAFE wait and return an error code that causes its caller
* to understand that the current operation has been interrupted, and its
* caller should return a similar error code, and so on until the
* user/kernel boundary is reached. For Mach, the error code is usually KERN_ABORTED,
* for BSD it is EINTR.
*
* Debuggers rely on the safe abort mechanism - a signaled thread must return to
* the AST at the user/kernel boundary for the debugger to finish attaching.
*
* No wait/block will ever disappear a thread out from under the waiter. The block
* call will always either return or call the passed in continuation.
