/*! \file isc/app.h
* \brief ISC Application Support
*
* Dealing with program termination can be difficult, especially in a
* multithreaded program. The routines in this module help coordinate
* the shutdown process. They are used as follows by the initial (main)
* thread of the application:
*
*\li isc_app_start(); Call very early in main(), before
* any other threads have been created.
*
*\li isc_app_run(); This will post any on-run events,
* and then block until application
* shutdown is requested. A shutdown
* request is made by calling
* isc_app_shutdown(), or by sending
* SIGINT or SIGTERM to the process.
* After isc_app_run() returns, the
* application should shutdown itself.
*
*\li isc_app_finish(); Call very late in main().
*
* Applications that want to use SIGHUP/isc_app_reload() to trigger reloading
* should check the result of isc_app_run() and call the reload routine if
* the result is ISC_R_RELOAD. They should then call isc_app_run() again
* to resume waiting for reload or termination.
*
* Use of this module is not required. In particular, isc_app_start() is
* NOT an ISC library initialization routine.
*
* This module also supports per-thread 'application contexts'. With this
* mode, a thread-based application will have a separate context, in which
* it uses other ISC library services such as tasks or timers. Signals are
* not caught in this mode, so that the application can handle the signals
* in its preferred way.
*
* \li MP:
* Clients must ensure that isc_app_start(), isc_app_run(), and
* isc_app_finish() are called at most once. isc_app_shutdown()
* is safe to use by any thread (provided isc_app_start() has been
* called previously).
*
* The same note applies to isc_app_ctxXXX() functions, but in this case
* it's a per-thread restriction. For example, a thread with an
* application context must ensure that isc_app_ctxstart() with the
* context is called at most once.
*
* \li Reliability:
* No anticipated impact.
*
* \li Resources:
* None.
*
* \li Security:
* No anticipated impact.
*
* \li Standards:
* None.

* \brief provide a back trace of the running process to help debug problems.
*
* This module tries to get a back trace of the process using some platform
* dependent way when available. It also manages an internal symbol table
* that maps function addresses used in the process to their textual symbols.
* This module is expected to be used to help debug when some fatal error
* happens.
*
* IMPORTANT NOTE: since the (major) intended use case of this module is
* dumping a back trace on a fatal error, normally followed by self termination,
* functions defined in this module generally doesn't employ assertion checks
* (if it did, a program bug could cause infinite recursive calls to a
* backtrace function). These functions still perform minimal checks and return
* ISC_R_FAILURE if they detect an error, but the caller should therefore be
* very careful about the use of these functions, and generally discouraged to
* use them except in an exit path. The exception is
* isc_backtrace_getsymbolfromindex(), which is expected to be used in a
* non-error-handling context and validates arguments with assertion checks.

* \brief Bitstring manipulation functions.
*
* A bitstring is a packed array of bits, stored in a contiguous
* sequence of octets. The "most significant bit" (msb) of a bitstring
* is the high bit of the first octet. The "least significant bit" of a
* bitstring is the low bit of the last octet.
*
* Two bit numbering schemes are supported, "msb0" and "lsb0".
*
* In the "msb0" scheme, bit number 0 designates the most significant bit,
* and any padding bits required to make the bitstring a multiple of 8 bits
* long are added to the least significant end of the last octet.
*
* In the "lsb0" scheme, bit number 0 designates the least significant bit,
* and any padding bits required to make the bitstring a multiple of 8 bits
* long are added to the most significant end of the first octet.
*
* E.g., consider the bitstring "11010001111". This bitstring is 11 bits
* long and will take two octets. Let "p" denote a pad bit. In the msb0
* encoding, it would be
*
* \verbatim
* Octet 0 Octet 1

* The entropy object is locked internally. All callbacks into
* application-provided functions (for setup, gathering, and
* shutdown of sources) are guaranteed to be called with the
* entropy API lock held. This means these functions are
* not permitted to call back into the entropy API.
*
* \li Reliability:
* No anticipated impact.
*
* \li Resources:
* A buffer, used as an entropy pool.
*
* \li Security:
* While this code is believed to implement good entropy gathering
* and distribution, it has not been reviewed by a cryptographic
* expert.
* Since the added entropy is only as good as the sources used,
* this module could hand out bad data and never know it.

#ifndef ISC_FSACCESS_H
#define ISC_FSACCESS_H 1
/*! \file isc/fsaccess.h
* \brief The ISC filesystem access module encapsulates the setting of file
* and directory access permissions into one API that is meant to be
* portable to multiple operating systems.
*
* The two primary operating system flavors that are initially accommodated
* are POSIX and Windows NT 4.0 and later. The Windows NT access model is
* considerable more flexible than POSIX's model (as much as I am loathe to
* admit it), and so the ISC API has a higher degree of complexity than would
* be needed to simply address POSIX's needs.
*
* The full breadth of NT's flexibility is not available either, for the
* present time. Much of it is to provide compatibility with what Unix
* programmers are expecting. This is also due to not yet really needing all
* of the functionality of an NT system (or, for that matter, a POSIX system)
* in BIND9, and so resolving how to handle the various incompatibilities has
* been a purely theoretical exercise with no operational experience to
* indicate how flawed the thinking may be.
*
* Some of the more notable dumbing down of NT for this API includes:
*
*\li Each of FILE_READ_DATA and FILE_READ_EA are set with #ISC_FSACCESS_READ.
*
* \li All of FILE_WRITE_DATA, FILE_WRITE_EA and FILE_APPEND_DATA are
* set with #ISC_FSACCESS_WRITE. FILE_WRITE_ATTRIBUTES is not set
* so as to be consistent with Unix, where only the owner of the file
* or the superuser can change the attributes/mode of a file.
*
* \li Both of FILE_ADD_FILE and FILE_ADD_SUBDIRECTORY are set with
* #ISC_FSACCESS_CREATECHILD. This is similar to setting the WRITE
* permission on a Unix directory.
*
* \li SYNCHRONIZE is always set for files and directories, unless someone
* can give me a reason why this is a bad idea.
*
* \li READ_CONTROL and FILE_READ_ATTRIBUTES are always set; this is
* consistent with Unix, where any file or directory can be stat()'d
* unless the directory path disallows complete access somewhere along
* the way.
*
* \li WRITE_DAC is only set for the owner. This too is consistent with
* Unix, and is tighter security than allowing anyone else to be
* able to set permissions.
*
* \li DELETE is only set for the owner. On Unix the ability to delete
* a file is controlled by the directory permissions, but it isn't
* currently clear to me what happens on NT if the directory has
* FILE_DELETE_CHILD set but a file within it does not have DELETE
* set. Always setting DELETE on the file/directory for the owner
* gives maximum flexibility to the owner without exposing the
* file to deletion by others.
*
* \li WRITE_OWNER is never set. This too is consistent with Unix,
* and is also tighter security than allowing anyone to change the
* ownership of the file apart from the superu..ahem, Administrator.
*
* \li Inheritance is set to NO_INHERITANCE.
*
* Unix's dumbing down includes:
*
* \li The sticky bit cannot be set.
*
* \li setuid and setgid cannot be set.
*
* \li Only regular files and directories can be set.
*
* The rest of this comment discusses a few of the incompatibilities
* between the two systems that need more thought if this API is to
* be extended to accommodate them.
*
* The Windows standard access right "DELETE" doesn't have a direct
* equivalent in the Unix world, so it isn't clear what should be done
* with it.
*
* The Unix sticky bit is not supported. While NT does have a concept
* of allowing users to create files in a directory but not delete or
* rename them, it does not have a concept of allowing them to be deleted
* if they are owned by the user trying to delete/rename. While it is
* probable that something could be cobbled together in NT 5 with inheritance,
* it can't really be done in NT 4 as a single property that you could
* set on a directory. You'd need to coordinate something with file creation
* so that every file created had DELETE set for the owner but noone else.
*
* On Unix systems, setting #ISC_FSACCESS_LISTDIRECTORY sets READ.
* ... setting either #ISC_FSACCESS_CREATECHILD or #ISC_FSACCESS_DELETECHILD
* sets WRITE.
* ... setting #ISC_FSACCESS_ACCESSCHILD sets EXECUTE.
*
* On NT systems, setting #ISC_FSACCESS_LISTDIRECTORY sets FILE_LIST_DIRECTORY.
* ... setting #ISC_FSACCESS_CREATECHILD sets FILE_CREATE_CHILD independently.
* ... setting #ISC_FSACCESS_DELETECHILD sets FILE_DELETE_CHILD independently.
* ... setting #ISC_FSACCESS_ACCESSCHILD sets FILE_TRAVERSE.
*
* Unresolved: XXXDCL
* \li What NT access right controls the ability to rename a file?
* \li How does DELETE work? If a directory has FILE_DELETE_CHILD but a
* file or directory within it does not have DELETE, is that file
* or directory deletable?
* \li To implement isc_fsaccess_get(), mapping an existing Unix permission
* mode_t back to an isc_fsaccess_t is pretty trivial; however, mapping
* an NT DACL could be impossible to do in a responsible way.
* \li Similarly, trying to implement the functionality of being able to
* say "add group writability to whatever permissions already exist"
* could be tricky on NT because of the order-of-entry issue combined
* with possibly having one or more matching ACEs already explicitly
* granting or denying access. Because this functionality is
* not yet needed by the ISC, no code has been written to try to
* solve this problem.

/*****
***** Module Info
*****/
/*! \file isc/hash.h
*
* \brief The hash API
* provides an unpredictable hash value for variable length data.
* A hash object contains a random vector (which is hidden from clients
* of this API) to make the actual hash value unpredictable.
*
* The algorithm used in the API guarantees the probability of hash
* collision; in the current implementation, as long as the values stored
* in the random vector are unpredictable, the probability of hash
* collision between arbitrary two different values is at most 1/2^16.
*
* Although the API is generic about the hash keys, it mainly expects
* DNS names (and sometimes IPv4/v6 addresses) as inputs. It has an
* upper limit of the input length, and may run slow to calculate the
* hash values for large inputs.
*
* This API is designed to be general so that it can provide multiple
* different hash contexts that have different random vectors. However,
* it should be typical to have a single context for an entire system.
* To support such cases, the API also provides a single-context mode.
*
* \li MP:
* The hash object is almost read-only. Once the internal random vector
* is initialized, no write operation will occur, and there will be no
* need to lock the object to calculate actual hash values.
*
* \li Reliability:
* In some cases this module uses low-level data copy to initialize the
* random vector. Errors in this part are likely to crash the server or
* corrupt memory.
*
* \li Resources:
* A buffer, used as a random vector for calculating hash values.
*
* \li Security:
* This module intends to provide unpredictable hash values in
* adversarial environments in order to avoid denial of service attacks
* to hash buckets.
* Its unpredictability relies on the quality of entropy to build the
* random vector.
*
* \li Standards:
* None.

*
* \brief A buffer is a region of memory, together with a set of related subregions.
* Buffers are used for parsing and I/O operations.
*
* The 'used region' and the 'available' region are disjoint, and their
* union is the buffer's region. The used region extends from the beginning
* of the buffer region to the last used byte. The available region
* extends from one byte greater than the last used byte to the end of the
* buffer's region. The size of the used region can be changed using various
* buffer commands. Initially, the used region is empty.
*
* The used region is further subdivided into two disjoint regions: the
* 'consumed region' and the 'remaining region'. The union of these two
* regions is the used region. The consumed region extends from the beginning
* of the used region to the byte before the 'current' offset (if any). The
* 'remaining' region the current pointer to the end of the used
* region. The size of the consumed region can be changed using various
* buffer commands. Initially, the consumed region is empty.
*
* The 'active region' is an (optional) subregion of the remaining region.
* It extends from the current offset to an offset in the remaining region
* that is selected with isc_buffer_setactive(). Initially, the active region
* is empty. If the current offset advances beyond the chosen offset, the
* active region will also be empty.
*

*
* a == base of buffer.

*

*
* base is a valid pointer to length bytes of memory
*
* 0 <= used <= length
*
* 0 <= current <= used
*
* 0 <= active <= used
* (although active < current implies empty active region)

* 0 means "match any type"; any other value will only match the given
* type.
*
* It's possible that a client will attempt to define a <key, type, value>
* tuple when a tuple with the given key and type already exists in the table.
* What to do in this case is specified by the client. Possible policies are:
*
*\li #isc_symexists_reject Disallow the define, returning #ISC_R_EXISTS
*\li #isc_symexists_replace Replace the old value with the new. The
* undefine action (if provided) will be called
* with the old <key, type, value> tuple.
*\li #isc_symexists_add Add the new tuple, leaving the old tuple in
* the table. Subsequent lookups will retrieve
* the most-recently-defined tuple.
*
* A lookup of a key using type 0 will return the most-recently defined
* symbol with that key. An undefine of a key using type 0 will undefine the
* most-recently defined symbol with that key. Trying to define a key with
* type 0 is illegal.
*
* The symbol table library does not make a copy the key field, so the
* caller must ensure that any key it passes to isc_symtab_define() will not
* change until it calls isc_symtab_undefine() or isc_symtab_destroy().
*
* A user-specified action will be called (if provided) when a symbol is
* undefined. It can be used to free memory associated with keys and/or
* values.
*
* A symbol table is implemented as a hash table of lists; the size of the
* hash table is set by the 'size' parameter to isc_symtbl_create(). When
* the number of entries in the symbol table reaches three quarters of this
* value, the hash table is reallocated with size doubled, in order to
* optimize lookup performance. This has a negative effect on insertion
* performance, which can be mitigated by sizing the table appropriately
* when creating it.
*
* \li MP:
* The callers of this module must ensure any required synchronization.
*
* \li Reliability:
* No anticipated impact.

/*****
***** Module Info
*****/
/*! \file isc/task.h
* \brief The task system provides a lightweight execution context, which is
* basically an event queue.
* When a task's event queue is non-empty, the
* task is runnable. A small work crew of threads, typically one per CPU,
* execute runnable tasks by dispatching the events on the tasks' event
* queues. Context switching between tasks is fast.
*
* \li MP:
* The module ensures appropriate synchronization of data structures it
* creates and manipulates.
* The caller must ensure that isc_taskmgr_destroy() is called only
* once for a given manager.
*
* \li Reliability:
* No anticipated impact.
*
* \li Resources:
* TBS
*
* \li Security:
* No anticipated impact.
*
* \li Standards:
* None.
*
* \section purge Purging and Unsending
*
* Events which have been queued for a task but not delivered may be removed
* from the task's event queue by purging or unsending.
*
* With both types, the caller specifies a matching pattern that selects
* events based upon their sender, type, and tag.
*
* Purging calls isc_event_free() on the matching events.
*
* Unsending returns a list of events that matched the pattern.
* The caller is then responsible for them.
*
* Consumers of events should purge, not unsend.
*
* Producers of events often want to remove events when the caller indicates
* it is no longer interested in the object, e.g. by canceling a timer.
* Sometimes this can be done by purging, but for some event types, the
* calls to isc_event_free() cause deadlock because the event free routine
* wants to acquire a lock the caller is already holding. Unsending instead
* of purging solves this problem. As a general rule, producers should only
* unsend events which they have sent.

/*! \file isc/timer.h
* \brief Provides timers which are event sources in the task system.
*
* Three types of timers are supported:
*
*\li 'ticker' timers generate a periodic tick event.
*
*\li 'once' timers generate an idle timeout event if they are idle for too
* long, and generate a life timeout event if their lifetime expires.
* They are used to implement both (possibly expiring) idle timers and
* 'one-shot' timers.
*
*\li 'limited' timers generate a periodic tick event until they reach
* their lifetime when they generate a life timeout event.
*
*\li 'inactive' timers generate no events.
*
* Timers can change type. It is typical to create a timer as
* an 'inactive' timer and then change it into a 'ticker' or
* 'once' timer.
*
*\li MP:
* The module ensures appropriate synchronization of data structures it
* creates and manipulates.
* Clients of this module must not be holding a timer's task's lock when
* making a call that affects that timer. Failure to follow this rule
* can result in deadlock.
* The caller must ensure that isc_timermgr_destroy() is called only
* once for a given manager.
*
* \li Reliability:
* No anticipated impact.
*
* \li Resources:
* TBS
*
* \li Security:
* No anticipated impact.
