An extra 2 + * bytes will be allocated for the client to append CRLF if wanted. The + * value of *LEN will include these two bytes. + * + * All the marshalling functions produce a buffer with the fields + * separated by colons (except for the hostent marshalling, which uses '@' + * to separate fields).

This is because RFC2553 is silent about which error + * code must be returned for which situation. + *\li IPv4 classful (shortened) form. RFC2553 is silent about it. XNET 5.2 + * says to use inet_aton() to convert IPv4 numeric to binary (allows + * classful form as a result). + * current code - disallow classful form for IPv4 (due to use of inet_pton). + *\li freeaddrinfo(NULL). RFC2553 is silent about it. XNET 5.2 says it is + * invalid. + * current code - SEGV on freeaddrinfo(NULL) + * Note: + *\li We use getipnodebyname() just for thread-safeness. There's no intent + * to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to + * getipnodebyname(). + *\li The code filters out AFs that are not supported by the kernel, + * when globbing NULL hostname (to loopback, or wildcard). Is it the right + * thing to do? What is the relationship with post-RFC2553 AI_ADDRCONFIG + * in ai_flags? + *\li (post-2553) semantics of AI_ADDRCONFIG itself is too vague. + * (1) what should we do against numeric hostname (2) what should we do + * against NULL hostname (3) what is AI_ADDRCONFIG itself. AF not ready? + * non-loopback address configured? global address configured? + * \par Additional Issue: + * To avoid search order issue, we have a big amount of code duplicate + * from gethnamaddr.c and some other places. The issues that there's no + * lower layer function to lookup "IPv4 or IPv6" record. Calling + * gethostbyname2 from getaddrinfo will end up in wrong search order, as + * follows: + * \li The code makes use of following calls when asked to resolver with + * ai_family = PF_UNSPEC: + *\code getipnodebyname(host, AF_INET6); + * getipnodebyname(host, AF_INET); + *\endcode + * \li This will result in the following queries if the node is configure to + * prefer /etc/hosts than DNS: + *\code + * lookup /etc/hosts for IPv6 address + * lookup DNS for IPv6 address + * lookup /etc/hosts for IPv4 address + * lookup DNS for IPv4 address + *\endcode + * which may not meet people's requirement. + * \li The right thing to happen is to have underlying layer which does + * PF_UNSPEC lookup (lookup both) and return chain of addrinfos. + * This would result in a bit of code duplicate with _dns_ghbyname() and + * friends. + */ + +#include "port_before.h" + +#include <sys/types.h> +#include <sys/param.h> +#include <sys/socket.h> + +#include <net/if.h> +#include <netinet/in.h> + +#include <arpa/inet.h> +#include <arpa/nameser.h> + +#include <netdb.h> +#include <resolv.h> +#include <string.h> +#include <stdlib.h> +#include <stddef.h> +#include <ctype.h> +#include <unistd.h> +#include <stdio.h> +#include <errno.h> + +#include <stdarg.h> + +#include <irs.h> +#include <isc/assertions.h> + +#include "port_after.h" + +#include "irs_data.h" + +#define SUCCESS 0 +#define ANY 0 +#define YES 1 +#define NO 0 + +static const char in_addrany[] = { 0, 0, 0, 0 };

provides multiple outstanding asynchronous timers and I/O +to a cooperating application. The model is similar to that of the X +Toolkit, in that events are registered with the library and the application +spends most of its time in the +.Fn evMainLoop +function. If an application already has a main loop, it can safely register +events with this library as long as it periodically calls the +.Fn evGetNext +and +.Fn evDispatch +functions. (Note that +.Fn evGetNext +has both polling and blocking modes.) +.Pp +The function +.Fn evCreate +creates an event context which is needed by all the other functions in this +library. All information used internally by this library is bound to this +context, rather than to static storage. This makes the library +.Dq thread safe , +and permits other library functions to use events without +disrupting the application's use of events. +.Pp +The function +.Fn evDestroy +destroys a context that has been created by +.Fn evCreate . +All dynamic memory bound to this context will be freed. An implicit +.Fn evTimerClear +will be done on all timers set in this event context. An implicit +.Fn evDeselectFD +will be done on all file descriptors selected in this event context. +.Pp +The function +.Fn evGetNext +potentially waits for and then retrieves the next asynchronous event, +placing it in the object of the +.Fa ev +pointer argument. The following +.Fa options +are available: +.Fa EV_POLL , +meaning that +.Fn evGetNext +should not block, but rather return +.Dq Fa -1 +with +.Fa errno +set to +.Fa EWOULDBLOCK +if no events have occurred; +.Fa EV_WAIT , +which tells +.Fn evGetNext +to block internally until the next event occurs; and +.Fa EV_NULL , +which tells +.Fn evGetNext +that it should return a special +.Dq no-op +event, which is ignored by +.Fn evDispatch +but handled correctly by +.Fn evDrop . +.Fa EV_NULL +can be necessary to the correct functioning of a caller\-written equivilent to +.Fn evMainLoop , +wherein perterbations caused by external system events must be polled for, and +the default behaviour of internally ignoring such events is undesirable. +Note that +.Fa EV_POLL +and +.Fa EV_WAIT +are mutually exclusive. +.Pp +The function +.Fn evDispatch +dispatches an event retrieved by +.Fn evGetNext . +This usually involves calling the function that was associated with the event +when the event was registered with +.Fn evSetTimer , +.Fn evResetTimer , +or +.Fn evSelectFD . +All events retrieved by +.Fn evGetNext +must be given over to +.Fn evDispatch +at some point, since there is some dynamic memory associated with each event. +.Pp +The function +.Fn evDrop +deallocates dynamic memory that has been allocated by +.Fn evGetNext . +Calling +.Fn evDispatch +has the side effect of calling +.Fn evDrop , +but if you are going to drop the event rather than dispatch it, you will have +to call +.Fn evDrop +directly. +.Pp +The function +.Fn evMainLoop +is just: +.Bd -literal -offset indent +while ((x = evGetNext(opaqueCtx, &event, EV_WAIT)) == 0) + if ((x = evDispatch(opaqueCtx, event)) < 0) + break; +return (x); +.Ed +.Pp +In other words, get events and dispatch them until an error occurs. One such +error would be that all the events under this context become unregistered; in +that event, there will be nothing to wait for and +.Fn evGetNext +becomes an undefined operation. +.Pp +The function +.Fn evConsTime +is a constructor for +.Dq Fa struct timespec +which allows these structures to be created and then passed as arguments to +other functions without the use of temporary variables. (If C had inline +constructors, there would be no need for this function.) +.Pp +The functions +.Fn evTimeSpec +and +.Fn evTimeVal +are utilities which allow the caller to convert a +.Dq Fa struct timeval +to a +.Dq Fa struct timespec +(the function of +.Fn evTimeSpec ) +or vice versa (the function of +.Fn evTimeVal ) . +Note that the name of the function indicates the type of the return value. +.Pp +The function +.Fn evAddTime +adds two +.Dq Fa struct timespec +values and returns the result as a +.Dq Fa struct timespec . +.Pp +The function +.Fn evSubTime +subtracts its second +.Dq Fa struct timespec +argument from its first +.Dq Fa struct timespec +argument and returns the result as a +.Dq Fa struct timespec . +.Pp +The function +.Fn evCmpTime +compares its two +.Dq Fa struct timespec +arguments and returns an +.Dq Fa int +that is less than zero if the first argument specifies an earlier time than +the second, or more than zero if the first argument specifies a later time +than the second, or equal to zero if both arguments specify the same time. +.Pp +The function +.Fn evNowTime +returns a +.Dq Fa struct timespec +which either describes the current time +(using +.Xr clock_gettime 2 or +.Xr gettimeofday 2 ) , +if successful, or has its fields set to zero, if there is an error. +(In the latter case, the caller can check +.Va errno , +since it will be set by +.Xr gettimeofday 2 . ) +The timestamp returned may not be UTC time if +the "monotime" option has been enabled with +.Fn evSetOption . +.Pp +The function +.Fn evUTCTime +is like +.Fn evNowTime +except the result is always on the UTC timescale. +.Pp +The function +.Fn evLastEventTime +returns the +.Dq Fa struct timespec +which describes the last time that certain events happened to the +event context indicated by +.Fa opaqueCtx . +This value is updated by +.Fn evCreate +and +.Fn evGetNext +(upon entry and after +.Xr select 2 +returns); it is routinely compared with other times in the internal handling +of, e.g., timers. +.Pp +The function +.Fn evSetTimer +registers a timer event, which will be delivered as a function call to the +function specified by the +.Fa func +argument. The event will be delivered at absolute time +.Fa due , +and then if time +.Fa inter +is not equal to +.Dq Fn evConsTime 0 0 , +subsequently at intervals equal to time +.Fa inter . +As a special case, specifying a +.Fa due +argument equal to +.Dq Fn evConsTime 0 0 +means +.Dq due immediately . +The +.Fa opaqueID +argument, if specified as a value other than +.Fa NULL , +will be used to store the resulting +.Dq timer \s-1ID\s+1 , +useful as an argument to +.Fn evClearTimer . +Note that in a +.Dq one\-shot +timer (which has an +.Fa inter +argument equal to +.Dq Fa evConsTime(0,0) ) +the user function +.Fa func +should deallocate any dynamic memory that is uniquely bound to the +.Fa uap , +since no handles to this memory will exist within the event library +after a one\-shot timer has been delivered. +.Pp +The function +.Fn evResetTimer +resets the values of the timer specified by +.Fa id +to the given arguments. The arguments are the same as in the description of +.Fn evSetTimer +above. +.Pp +The function +.Fn evClearTimer +will unregister the timer event specified by +.Fa id . +Note that if the +.Fa uap +specified in the corresponding +.Fn evSetTimer +call is uniquely bound to any dynamic memory, then that dynamic memory should +be freed by the caller before the handle is lost. After a call to +.Fn evClearTimer , +no handles to this +.Fa uap +will exist within the event library. +.Pp +The function +.Fn evConfigTimer +can be used to manipulate other aspects of a timer. +Currently two modes are defined "rate" and "interval" which affect the +way recurrent timers are scheduled. +The default mode is "interval" where the event gets scheduled +.Fa inter +after last time it was run. +If mode "rate" is selected the event gets scheduled +.Fa inter +after last time it was scheduled. +For both "rate" and "interval" the numerical argument +.Fa value +is ignored. +.Pp +The function +.Fn evSetIdleTimer +is similar to (and built on) +.Fn evSetTimer ; +it registers an idle timer event which provides for the function call to +.Fa func +to occur. However, for an +.Em idle +timer, the call will occur after at least +.Dq Fa max_idle +time has passed since the time the idle timer was +.Dq last touched ; +originally, this is set to the time returned by +.Fn evLastEventTime +(described above) for the event context specified by +.Fa opaqueCtx . +This is a +.Dq one\-shot +timer, but the time at which the +.Fa func +is actually called can be changed by recourse to +.Fn evTouchIdleTimer +(described below). The pointer to the underlying +.Dq timer \s-1ID\s+1 +is returned in +.Fa opaqueID , +if it is +.No non- Ns Dv NULL . +.Pp +The +.Fn evTouchIdleTimer +function updates the idle timer associated with +.Fa id , +setting its idea of the time it was last accessed to the value returned by +.Fn evLastEventTime +(described above) for the event context specified by +.Fa opaqueCtx . +This means that the idle timer will expire after at least +.Fa max_idle +time has passed since this (possibly new) time, providing a caller mechanism +for resetting the call to the +.Fa func +associated with the idle timer. (See the description of +.Fn evSetIdleTimer , +above, for information about +.Fa func +and +.Fa max_idle . ) +.Pp +The +.Fn evResetIdleTimer +function reschedules a timer and resets the callback function and its argument. +Note that resetting a timer also ``touches'' it. +.Pp +The +.Fn evClearIdleTimer +function unregisters the idle timer associated with +.Fa id . +See the discussion under +.Fn evClearTimer , +above, for information regarding caller handling of the +.Fa uap +associated with the corresponding +.Fn evSetIdleTimer +call. +.Pp +The function +.Fn evWaitFor +places the function +.Fa func +on the given event context's wait queue with the associated (possibly +.Dv NULL ) +.Dq Fa tag ; +if +.Fa id +is +.No non- Ns Dv NULL , +then it will contain the +.Dq wait \s-1ID\s+1 +associated with the created queue element. +.Pp +The function +.Fn evDo +marks +.Em all +of the +.Dq waiting +functions in the given event context's wait queue with the associated (possibly +.Dv NULL ) +.Dq Fa tag +as runnable. This places these functions in a +.Dq done +queue which will be read by +.Fn evGetNext . +.Pp +The function +.Fn evUnwait +will search for the +.Dq wait \s-1ID\s+1 +.Fa id +in the wait queue of the given event context; if an element with the given +.Fa id +is not found, then the +.Dq done +queue of that context is searched. If found, the queue element is removed +from the appropriate list. +.Pp +The function +.Fn evDefer +causes a function (specified as +.Fa func , +with argument +.Fa uap ) +to be dispatched at some later time. Note that the +.Fa tag +argument to +.Fa func +will always be +.Fa NULL +when dispatched. +.Pp +The function +.Fn evSelectFD +registers a file I/O event for the file descriptor specified by +.Fa fd . +Bits in the +.Fa eventmask +argument are named +.Fa EV_READ , +.Fa EV_WRITE , +and +.Fa EV_EXCEPT . +At least one of these bits must be specified. If the +.Fa id +argument is not equal to +.Fa NULL , +it will be used to store a unique ``file event \s-1ID\s+1'' for this event, +which is useful in subsequent calls to +.Fn evDeselectFD . +A file descriptor will be made nonblocking using the +.Fa O_NONBLOCK +flag with +.Xr fcntl 2 +on its first concurrent registration via +.Fn evSelectFD . +An +.Fn evSelectFD +remains in effect until cancelled via +.Fn evDeselectFD . +.Pp +The function +.Fn evDeselectFD +unregisters the ``file event'' specified by the +.Fa id +argument. If the corresponding +.Fa uap +uniquely points to dynamic memory, that memory should be freed before its +handle is lost, since after a call to +.Fn evDeselectFD , +no handles to this event's +.Fa uap +will remain within the event library. A file descriptor will be taken out of +nonblocking mode (see +.Fa O_NONBLOCK +and +.Xr fcntl 2 ) +when its last event registration is removed via +.Fn evDeselectFD , +if it was in blocking mode before the first registration via +.Fn evSelectFD . +.Pp +The function +.Fn evConsIovec +is a constructor for a single +.Ft struct iovec +structure, which is useful for +.Fn evWrite +and +.Fn evRead . +.Pp +The functions +.Fn evWrite +and +.Fn evRead +start asynchronous stream I/O operations on file descriptor +.Fa fd . +The data to be written or read is in the scatter/gather descriptor specified by +.Fa iov +and +.Fa cnt . +The supplied function +.Fa func +will be called with argument +.Fa uap +when the I/O operation is complete. If +.Fa id +is not +.Fa NULL , +it will be filled a with the stream event identifier suitable for use with +.Fn evCancelRW . +.Pp +The function +.Fn evCancelRW +extinguishes an outstanding +.Fn evWrite +or +.Fn evRead +call. System I/O calls cannot always be cancelled, but you are guaranteed +that the +.Fa func +function supplied to +.Fn evWrite +or +.Fn evRead +will not be called after a call to +.Fn evCancelRW . +Care should be taken not to deallocate or otherwise reuse the space pointed +to by the segment descriptors in +.Fa iov +unless the underlying file descriptor is closed first. +.Pp +The function +.Fn evTimeRW +sets the stream associated with the given stream \s-1ID\s+1 +.Dq Fa id +to have the idle timer associated with the timer \s-1ID\s+1 +.Dq Fa timer . +.Pp +The function +.Fn evUntimeRW +says that the stream associated with the given stream \s-1ID\s+1 +.Dq Fa id +should ignore its idle timer, if present. +.Pp +The functions +.Fn evListen , +.Fn evConnect , +and +.Fn evCancelConn +can be used to manage asynchronous incoming and outgoing socket connections. +Sockets to be used with these functions should first be created with +.Xr socket 2 +and given a local name with +.Xr bind 2 . +It is extremely unlikely that the same socket will ever be +useful for both incoming and outgoing connections. The +.Fa id +argument to +.Fn evListen +and +.Fn evConnect +is either +.Fa NULL +or the address of a +.Ft evFileID +variable which can then be used in a subsequent call to +.Fn evCancelConn . +.Pp +After a call to +.Fn evListen , +each incoming connection arriving on +.Fa fd +will cause +.Fa func +to be called with +.Fa uap +as one of its arguments. +.Fn evConnect +initiates an outgoing connection on +.Fa fd +to destination address +.Fa ra +(whose length is +.Fa ralen ) . +When the connection is complete, +.Fa func +will be called with +.Fa uap +as one of its arguments. The argument +.Fa fd +to +.Fn \*(lp*func\*(rp +will be +.Fa -1 +if an error occurred that prevented this connection from completing +successfully. In this case +.Fn errno +will have been set and the socket described by +.Fa fd +will have been closed. The +.Fn evCancelConn +function will prevent delivery of all pending and subsequent +events for the outstanding connection. The +.Fn evHold +function will suspend the acceptance of new connections on the listener +specified by +.Fa id . +Connections will be queued by the protocol stack up to the system's limit. The +.Fn evUnhold +function will reverse the effects of +.Fn evHold , +allowing incoming connections to be delivered for listener +.Fa id . +The +.Fn evTryAccept +function will poll the listener specified by +.Fa id , +accepting a new connection if one is available, and queuing a connection event +for later retrieval by +.Fn evGetNext . +If the connection event queued is an accept error(), sys_errno will contain +the error code; otherwise it will be zero. All connection events queued by +.Fn evTryAccept +will be delivered by +.Fn evGetNext +before a new select is done on the listener. +.Pp +The function +.Fn evSetDebug +sets the debugging +.Fa level +and diagnostic +.Fa output +file handle for an event context. Greater numeric levels will +result in more verbose output being sent to the output FILE during program +execution. +.Pp +The function +.Fn evPrintf +prints a message with the format +.Dq Fa fmt +and the following arguments (if any), on the output stream associated +with the event context pointed to by +.Fa ctx . +The message is output if the event context's debug level is greater than +or equal to the indicated +.Fa level . +.Pp +The function +.Fn evInitID +will initialize an opaque +.Dq evConn \s-1ID\s+1 , +.Dq evFile \s-1ID\s+1 , +.Dq evStream \s-1ID\s+1 , +.Dq evTimer \s-1ID\s+1 , +.Dq evWait \s-1ID\s+1 , +.Dq evContext , +or +.Dq evEvent , +which is passed by reference to a state which +.Fn evTestID +will recognize. +This is useful to make a handle as "not in use". +.Pp +The function +.Fn evTestID +will examine an opaque \s-1ID\s+1 and return +.Dq TRUE +only if it is not in its initialized state. +.Pp +The functions +.Fn evGetOption +and +.Fn evSetOption +can be used to inspect and modify options. +Currently there is only one option, "monotime" and it is global for all +instances of eventlib so the ctx argument must be passed as NULL. +.Pp +The default value for the "monotime" option is zero which selects +the UTC timescale. +When set to a value of one, eventlib will use the +CLOCK_MONOTONIC timescale from +.Xr clock_gettime +instead. +The CLOCK_MONOTONIC timescale is never stepped and should +run at a rate as close to TAI as possible, so it is unaffected +when the system clock is set. +If timerevents should run at a predictable rate, set the value +to one, of they should run at a predictable time of day, leave +it at zero. +If the CLOCK_MONOTONIC timescale is not available on the system, +attempts to set/get this option will fail. +.Sh RETURN VALUES +All the functions whose return type is +.Dq Fa int +use the standard convention of returning zero (0) to indicate success, or +returning +.Dq Fa -1 +and setting +.Fa errno +to indicate failure. +.Sh FILE +.Pa heap.h , +which is in the +.Pa src/lib/isc +directory of the current +.Sy BIND +distribution. +.Sh ERRORS +The possible values for +.Fa errno +when one of the +.Dq Fa int +functions in this library returns +.Dq Fa -1 +include those of the Standard C Library and also: +.Bl -tag -width EWOULDBLOCKAA +.It Bq Er EINVAL +Some function argument has an unreasonable value. +.It Bq Er EINVAL +The specified file descriptor has an integer value greater than the default +.Fa FD_SETSIZE , +meaning that the application's limit is higher than the library's. +.It Bq Er ENOENT +The specified +.Dq event \s-1ID\s+1 +does not exist. +.It Bq Er EWOULDBLOCK +No events have occurred and the +.Fa EV_POLL +option was specified. +.It Bq Er EBADF +The specified signal was unblocked outside the library. +.El +.Sh SEE ALSO +.Xr gettimeofday 2 , +.Xr select 2 , +.Xr fcntl 3 , +.Xr malloc 3 , +.Xr @INDOT@named @SYS_OPS_EXT@ , +.Xr readv 3 , +.Xr writev 3 . +.Sh BUGS +This huge man page needs to be broken up into a handful of smaller ones. +.Sh HISTORY +The +.Nm eventlib +library was designed by Paul Vixie with excellent advice from his friends +and with tips 'o the cap to the X Consortium and the implementors of DEC SRC +Modula-3. diff --git a/lib/bind/isc/eventlib_p.h b/lib/bind/isc/eventlib_p.h new file mode 100644 index 0000000..5896553 --- /dev/null +++ b/lib/bind/isc/eventlib_p.h @@ -0,0 +1,281 @@ +/* + * Copyright (c) 2005 by Internet Systems Consortium, Inc.

The user defines a +priority scheme, and provides a function for comparison of the priority +of heap elements +(see the description of the +.Ft heap_higher_priority_func +function pointer, below). +.Pp +Each of the functions depends upon the +.Ft heap_context +type, which is a pointer to a +.Ft struct heap_context +.Pq see Pa heap.h No for more information . +.Pp +The +.Pa heap.h +header file also defines the following set of function +function pointers: +.Bd -literal -offset indent +typedef int (*heap_higher_priority_func)(void *, void *); +typedef void (*heap_index_func)(void *, int); +typedef void (*heap_for_each_func)(void *, void *); +.Ed +.Pp +These are pointers to user-defined functions. +The +.Ft heap_higher_priority_func +type is a pointer to a function which compares two +different heap (queue) elements and returns an +.Ft int +which answers the question, "Does the first queue element +have a higher priority than the second?" In other words, +a function pointer of this type +.Em must +return a number greater than zero +if the element indicated by the first argument is of a higher priority than +that indicated by the second element, and zero otherwise. +.Pp +The other two function pointers are documented in the descriptions +of +.Fn heap_new +.Pq Va heap_index_func +and +.Fn heap_for_each +.Pq Va heap_for_each_func , +below. +.Pp +The function +.Fn heap_new +initializes a +.Ft struct heap_context +and returns a pointer to it. The +.Fa higher_priority +function pointer +.Em must +be +.No non\- Ns Dv NULL . +As explained above, this refers to a +function supplied by the user which compares the priority of two different +queue or heap elements; see above for more information. +The second argument, +.Fa index , +is a pointer to a user-defined function whose arguments are +a heap element and its index in the heap. +.Fa Index +is intended to provide the user a means of knowing the internal index +of an element in the heap while maintaining the opacity of the implementation; +since the user has to know the actual indexes of heap elements in order to use, +e.g., +.Fn heap_delete +or +.Fn heap_element , +the user +.Fa index +function could store the index in the heap element, itself. If +.Fa index +is +.No non\- Ns Dv NULL , +then it is called +.Em whenever +the index of an element changes, allowing the user to stay up\-to\-date +with index changes. +The last argument, +.Fa array_size_increment +will be used, as its name suggests, by +.Xr malloc 3 +or +.Xr realloc 3 +to increment the array which implements the heap; if zero, a default value +will be used. +.Pp +The +.Fn heap_free +function frees the given +.Ft heap_context +argument +.Pq Fa ctx , +which also frees the entire +.Nm heap , +if it is +.No non\- Ns Dv NULL . +The argument +.Fa ctx +should be +.No non\- Ns Dv NULL . +.Pp +The +.Fn heap_insert +function is used to insert the new heap element +.Fa elt +into the appropriate place (priority\-wise) in the +.Ft heap +indicated by +.Fa ctx +(a pointer to a +.Ft heap_context ) . +If +.No non\- Ns Dv NULL , +the user-defined +.Ft higher_priority +function pointer associated with the indicated +.Nm heap +is used to determine that +.Dq appropriate place ; +the highest\-priority elements are at the front of the queue (top of +the heap). +(See the description of +.Fn heap_new , +above, for more information.) +.Pp +The function +.Fn heap_delete +is used to delete the +.Fa i\- Ns th +element of the queue (heap), and fixing up the queue (heap) from that +element onward via the priority as determined by the user function +pointed to by +.Ft higher_priority +function pointer +(see description of +.Fn heap_new , +above). +.Pp +.Fn heap_increased +.Pp +.Fn heap_decreased +.Pp +The +.Fn heap_element +function returns the +.Fa i\- Ns th +element of the queue/heap indicated by +.Fa ctx , +if possible. +.Pp +The +.Fn heap_for_each +function provides a mechanism for the user to increment through the entire +queue (heap) and perform some +.Fa action +upon each of the queue elements. This +.Fa action +is pointer to a user\-defined function with two arguments, the first of +which should be interpreted by the user's function as a heap element. The +second value passed to the user function is just the +.Fa uap +argument to +.Fn heap_for_each ; +this allows the user to specify additional arguments, if necessary, to +the function pointed to by +.Fa action . +.\" The following requests should be uncommented and +.\" used where appropriate.

(The fact that +.Dq more important +means +.Dq more negative , +under the current scheme, is an implementation detail; if a channel has +a priority of +.Dv log_error , +then it will +.Em not +log messages with the +.Dv log_warning +priority, but it +.Em will +log messages with the +.Dv log_error +or +.Dv log_critical +priority.) +.Pp +The +.Nm logging channel +also has an indication of the type of logging performed. Currently, +the supported +.Nm logging types +include (see also +.Sx Logging Types , +below): +.Bl -tag -width "log_syslog" -compact -offset indent +.It Dv log_syslog +for +.Xr syslog 3 Ns -style +logging +.It Dv log_file +for use of a file +.It Dv log_null +for +.Em no +logging +.El +A new logging channel is created by calling either +.Fn log_new_syslog_channel , +.Fn log_new_file_channel , +or +.Fn log_new_null_channel , +respectively. +When a channel is no longer to be used, it can be freed using +.Fn log_free_channel . +.Pp +Both +.Dv log_syslog +and +.Dv log_file +channel types can include more information; for instance, a +.Dv log_syslog Ns -type +channel allows the specification of a +.Xr syslog 3 Ns -style +.Dq facility , +and a +.Dv log_file Ns -type +channels allows the caller to set a maximum file size and number +of versions. (See +.Fn log_new_syslog_channel +or +.Fn log_new_file_channel , +below.) +Additionally, once a logging channel of type +.Dv log_file +is defined, the functions +.Fn log_open_stream +and +.Fn log_close_stream +can open or close the stream associated with the logging channel's logging +filename. The +.Fn log_get_stream +and +.Fn log_get_filename +functions return the stream or filename, respectively, of such a logging +channel. Also unique to logging channels of type +.Dv log_file +is the +.Fn log_set_file_owner +function, which tells the logging system what user and group ought to own +newly created files (which is only effective if the caller is privileged.) +.Pp +Callers provide +.Dq Nm categories , +determining both the number of such categories and any (optional) names. +Categories are like array indexes in C; if the caller declares +.Dq Va n +categories, then they are considered to run from 0 to +.Va n-1 ; +with this scheme, a category number would be invalid if it were negative or +greater than/equal to +.Va n . +Each category can have its own list of +.Nm logging channels +associated with it; we say that such a channel is +.Dq in +the particular category. +.Sy NOTE : +Individual logging channels can appear in more than one category. +.Pp +A +.Dq Nm logging context +is the set of all +.Nm logging channels +associated with the context's +.Nm categories ; +thus, a particular +.Nm category +scheme is associated with a particular +.Nm logging context . +.Sy NOTE : +A logging channel may appear in more than one logging context, and in +multiple categories within each logging context. +.Pp +Use +.Fn log_add_channel +and +.Fn log_remove_channel +to add or remove a logging channel to some category in a logging context. +To see if a given category in a logging context is being used, use the +Boolean test +.Fn log_category_is_active . +.Pp +A +.Nm logging context +can also have a +.Nm priority +(logging level) +and various flags associated with the whole context; in order to alter the +flags or change the priority of a context, use +.Fn log_option . +.Ss Message Priorities +Currently, five +.Nm priorities +(logging levels) are supported (they can also be found in the header file): +.Bd -literal -offset indent +#define log_critical (-5) +#define log_error (-4) +#define log_warning (-3) +#define log_notice (-2) +#define log_info (-1) +.Ed +.Pp +In the current implementation, logging messages which have a level greater +than 0 are considered to be debugging messages. +.Ss Logging Types +The three different +.Nm logging types +currently supported are different values of the enumerated type +.Ft log_output_type +(these are also listed in the header file): +.Bd -literal -offset indent +typedef enum { log_syslog, log_file, log_null } log_output_type; +.Ed +.Ss Logging Channel Flags +There are several flags which can be set on a logging channel; the flags +and their meanings are as follows (they are also found in the header file): +.Bl -tag -width "LOG_USE_CONTEXT_LEVEL " -offset indent +.It Dv LOG_CHANNEL_BROKEN +This is set only when some portion of +.Fn log_open_stream +fails: +.Xr open 2 +or +.Xr fdopen 3 +fail; +.Xr stat 2 +fails in a +.Dq bad +way; versioning or truncation is requested on a non-normal file. +.It Dv LOG_CHANNEL_OFF +This is set for channels opened by +.Fn log_new_null_channel . +.It Dv LOG_CLOSE_STREAM +If this flag is set, then +.Fn log_free_channel +will free a +.No non- Dv NULL +stream of a logging channel which is being +.Xr free 3 Ns -d +(if the logging channel is of type +.Dv log_file , +of course). +.It Dv LOG_PRINT_CATEGORY +If set, +.Fn log_vwrite +will insert the category name, if available, into logging messages which are +logged to channels of type +.Dv log_syslog +or +.Dv log_file . +.It Dv LOG_PRINT_LEVEL +If set, +.Fn log_vwrite +will insert a string identifying the message priority level into the +information logged to channels of type +.Dv log_syslog +or +.Dv log_file . +.It Dv LOG_REQUIRE_DEBUG +Only log debugging messages (i.e., those with a priority greater than zero). +.It Dv LOG_TIMESTAMP +If set, +.Fn log_vwrite +will insert a timestamp into logging messages which are logged to channels of +type +.Dv log_syslog +or +.Dv log_file . +.It Dv LOG_TRUNCATE +Truncate logging file when re-opened +.Fn ( log_open_stream +will +.Xr unlink 2 +the file and then +.Xr open 2 +a new file of the same name with the +.Dv O_EXCL +bit set). +.It Dv LOG_USE_CONTEXT_LEVEL +Use the logging context's priority or logging level, rather than the logging +channel's own priority. This can be useful for those channels which are +included in multiple logging contexts. +.El +.Ss FUNCTION DESCRIPTIONS +The function +.Fn log_open_stream +is for use with channels which log to a file; i.e., logging channels with a +.Va type +field set to +.Dq Dv log_file . +If the logging channel pointed to by +.Dq Fa chan +is valid, it attempts to open (and return) the stream associated with that +channel. If the stream is already opened, then it is returned; otherwise, +.Xr stat 2 +is used to test the filename for the stream. +.Pp +At this point, if the logging file is supposed to have different +.Va versions +(i.e., incremented version numbers; higher numbers indicate older versions +of the logging file). If so, then any existing versions are +.Xr rename 2 Ns -d +to have one version-number higher than previously, and the +.Dq current +filename for the stream is set to the +.Dq \&.0 +form of the name. Next, if the logging file is supposed to be truncated +(i.e., the +.Dv LOG_TRUNCATE +bit of the +.Va flags +field of the logging channel structure is set), then any file with the +.Dq current +filename for the stream is +.Xr unlink 2 Ns -d . +.Sy NOTE : +If the logging file is +.Em not +a regular file, and either of the above operations (version numbering +or truncation) is supposed to take place, a +.Dv NULL +file pointer is returned. +.Pp +Finally, the filename associated with the logging channel is +.Xr open 2 Ns -d +using the appropriate flags and a mode which sets the read/write permissions +for the user, group, and others. The file descriptor returned by +.Xr open 2 +is then passed to +.Xr fopen 3 , +with the append mode set, and the stream returned by this call is stored +in the +.Fa chan +structure and returned. +.Pp +If +.Fn log_open_stream +fails at any point, then the +.Dv LOG_CHANNEL_BROKEN +bit of the +.Va flags +field of the logging channel pointed to by +.Fa chan +is set, a +.Dv NULL +is returned, and +.Va errno +contains pertinent information. +.Pp +The +.Fn log_close_stream +function closes the stream associated with the logging channel pointed to by +.Dq Fa chan +(if +.Fa chan +is valid and the stream exists and can be closed properly by +.Xr fclose 3 ) . +The stream is set to +.Dv NULL +even if the call to +.Xr fclose 3 +fails. +.Pp +The function +.Fn log_get_stream +returns the stream associated with the logging channel pointed to by +.Dq Fa chan , +if it is +.No non- Ns Dv NULL +and specifies a logging channel which has a +.Dv FILE * +or stream associated with it. +.Pp +The +.Fn log_get_filename +function returns the name of the file associated with the logging channel +pointed to by +.Dq Fa chan , +if it is +.No non- Ns Dv NULL +and specifies a logging channel which has a file associated with it. +.Pp +The +.Fn log_vwrite +function performs the actual logging of a message to the various logging +channels of a logging context +.Fa lc . +The message consists of an +.Xr fprint 3 Ns -style +.Fa format +and its associated +.Fa args +(if any); it will be written to all logging channels in the given +.Fa category +which have a priority set to +.Fa level +or any +.Em less important +priority value. If the +.Fa category +is not valid or has no logging channels, then the category defaults to 0. +.Pp +There are a number of conditions under which a call to +.Fn log_vwrite +will not result in actually logging the message: if there is no logging channel +at even the default category (0), or if a given channel is either +.Dq broken +or +.Dq off +(i.e., its flags have +.Dv LOG_CHANNEL_BROKEN +or +.Dv LOG_CHANNEL_OFF +set, respectively), or if the logging channel channel is of type +.Dv log_null . +Additionally, if the logging channel's flag has +.Dv LOG_REQUIRE_DEBUG +set and the message is not a debugging message (i.e., has a level greater +than 0), then it will not be logged. +Finally, if the message's priority is less important than the +channel's logging level (the priority threshold), will not be logged. +.Sy NOTE : +If a logging channel's flag has +.Dv LOG_USE_CONTEXT_LEVEL +set, it will use the logging context's priority, rather than its own. +.Pp +If all of these hurdles are passed, then only +.Dv log_syslog +and +.Dv log_file +channels actually can have logging. For channels which use +.Xr syslog 3 , +the channel's +.Xr syslog 3 +facility is used in conjunction with a potentially modified form of the +message's priority level, since +.Xr syslog 3 +has its own system of priorities +.Pq Pa /usr/include/syslog.h . +All debug messages (priority >= 0) are mapped to +.Xr syslog 3 Ns 's +.Dv LOG_DEBUG +priority, all messages +.Dq more important +than +.Dv log_critical +are mapped to +.Dv LOG_CRIT , +and the priorities corresponding to the ones listed in the section +.Sx Message Priorities +are given the obvious corresponding +.Xr syslog 3 +priority. +.Pp +For +.Dv log_file +type logging channels, if the file size is greater than the maximum file +size, then no logging occurs. (The same thing happens if a +.Dv NULL +stream is encountered and +.Fn log_open_stream +fails to open the channel's stream.) +.Pp +For both logging to normal files and logging via +.Xr syslog 3 , +the value of the flags +.Dv LOG_TIMESTAMP , +.Dv LOG_PRINT_CATEGORY , +and +.Dv LOG_PRINT_LEVEL +are used in determining whether or not these items are included in the logged +information. +.Pp +The +.Fn log_write +function is merely a front-end to a call to +.Fn log_vwrite ; +see the description of that function, above, for more information. +.Pp +.Fn log_check +and +.Fn log_check_channel +are used to see if a contemplated logging call will actually generate any +output, which is useful when creating a log message involves non-trivial +work. +.Fn log_check +will return non-zero if a call to +.Fn log_vwrite +with the given +.Fa category +and +.Fa level +would generate output on any channels, and zero otherwise. +.Fn log_check_channel +will return non-zero if writing to the +.Fa chan +at the given +.Fa level +would generate output. +.Pp +The function +.Fn log_new_context +creates a new +.Nm logging context , +and stores this in the +.Dq Va opaque +field of the argument +.Dq Fa lc , +and opaque structure used internally.

If the +.Fa option +is +.Dv LOG_OPTION_DEBUG , +then a non-zero +.Fa value +results in setting the debug flag of the logging context, while a zero +.Fa value +means that the debug flag is reset. +.Pp +The +.Fn log_category_is_active +test returns a 1 if the given +.Fa category +of the indicated logging context +.Fa lc +has at least one logging channel, and 0, otherwise. +.Pp +The functions +.Fn log_new_syslog_channel , +.Fn log_new_file_channel , +and +.Fn log_new_null_channel +create a new channel of the type specified (thus, the difference in arguments); +the +.Dq Va type +field of the new +.Do +.Ft struct log_channel +.Dc +is always set to the appropriate value. +.Pp +The +.Fn log_new_syslog_channel +function +.Xr malloc 3 Ns -s +a new +.Ft struct log_channel +of +.Va type +.Dv log_syslog , +i.e., a logging channel which will use +.Xr syslog 3 . +The new structure is filled out with the +.Dq Fa flags , +.Dq Fa level , +and +.Dq Fa facility +which are given; the +.Va references +field is initialized to zero. +See +.Sx Logging Channel Flags +and +.Sx Message Priorities , +above, or the header file for information about acceptable values for +.Dq Fa flags , +and +.Dq Fa level . +The +.Dq Fa facility . +can be any valid +.Xr syslog 3 +facility; see the appropriate system header file or manpage for more +information. +.Pp +.Ft log_channel +.Fn log_new_file_channel "unsigned int flags" "int level" \ + "char *name" "FILE *stream" "unsigned int versions" \ + "unsigned long max_size" +.Pp +.Fn log_new_null_channel +.Pp +The functions +.Fn log_inc_references +and +.Fn log_dec_references +increment or decrements, respectively, the +.Va references +field of the logging channel pointed to by +.Dq Fa chan , +if it is a valid channel (and if the +.Va references +field is strictly positive, in the case of +.Fn log_dec_references ) . +These functions are meant to track changes in the number of different clients +which refer to the given logging channel. +.Pp +The +.Fn log_free_channel +function frees the +field of the logging channel pointed to by +.Dq Fa chan +if there are no more outstanding references to it.

The symmetric call is +.Fn memput , +which callers use to return a piece of memory obtained from +.Fn memget . +Statistics about memory usage are returned by +.Fn memstats , +which prints a report on the stream +.Fa out . +.Ss INTERNALS +Internally, linked lists of free memory blocks are stored in an array. +The size of this array is determined by the value +.Dv MEM_FREECOUNT , +currently set to 1100. In general, for any requested blocksize +.Dq Fa size , +any free blocks will be stored on the linked list at that index. +No free lists are managed for blocks greater than or equal to +.Dv MEM_FREECOUNT +bytes; instead, calls to +.Xr malloc 3 +or +.Xr free 3 +are made, directly. +.Pp +Since the blocks are actually stored as linked lists, they must at least +be large enough to hold a pointer to the next block. This size, which is +.Dv SMALL_SIZE_LIMIT , +is currently defined as +.Bd -literal -offset indent +#define SMALL_SIZE_LIMIT sizeof(struct { void *next; }) +.Ed +.Pp +Both +.Fn memget +and +.Fn memput +enforce this limit; for example, any call to +.Fn memget +requesting a block smaller than +.Dv SMALL_SIZE_LIMIT +bytes will actually be considered to be of size +.Dv SMALL_SIZE_LIMIT +internally. (Such a caller request will be logged for +.Fn memstats +purposes using the caller-requested +.Fa size ; +see the discussion of +.Fn memstats , +below, for more information.) +.Pp +Additionally, the requested +.Fa size +will be adjusted so that when a large +.Xr malloc 3 Ns No -d +chunk of memory is broken up into a linked list, the blocks will all fall on +the correct memory alignment boundaries. Thus, one can conceptualize a call +which mentions +.Fa size +as resulting in a +.Fa new_size +which is used internally. +.Pp +In order to more efficiently allocate memory, there is a +.Dq target +size for calls to +.Xr malloc 3 . +It is given by the pre-defined value +.Dv MEM_TARGET , +which is currently 4096 bytes. +For any requested block +.Fa size , +enough memory is +.Xr malloc 3 Ns No -d +in order to fill up a block of about +.Dv MEM_TARGET +bytes. +.No [ Ns Sy NOTE : +For allocations larger than +.Dv MEM_TARGET Ns No /2 +bytes, there is a +.Dq fudge factor +introduced which boosts the target size by 25% of +.Dv MEM_TARGET . +This means that enough memory for two blocks +will actually be allocated for any +.Fa size +such that +.Pq Dv MEM_TARGET Ns No / 3 +.No < Fa size No < +.Pq Dv MEM_TARGET Ns No *5/8 , +provided that the value of +.Dv MEM_FREECOUNT +is at least as large as the upper limit shown above.] +.Pp +.Ss FUNCTION DESCRIPTIONS +.Pp +The function +.Fn memget +returns a pointer to a block of memory of at least the requested +.Fa size . +After adjusting +.Fa size +to the value +.Va new_size +as mentioned above in the +.Sx INTERNALS +subsection, the internal array of free lists is checked. +If there is no block of the needed +.Va new_size , +then +.Fn memget +will +.Xr malloc 3 +a chunk of memory which is as many times as +.Va new_size +will fit into the target size. This memory is then turned into a linked list +of +.Va new_size Ns No -sized +blocks which are given out as requested; the last such block is the first one +returned by +.Fn memget . +If the requested +.Fa size +is zero or negative, then +.Dv NULL +is returned and +.Va errno +is set to +.Dv EINVAL ; +if +.Fa size +is larger than or equal to the pre-defined maximum size +.Dv MEM_FREECOUNT , +then only a single block of exactly +.Fa size +will be +.Xr malloc 3 Ns No -d +and returned. +.Pp +The +.Fn memput +call is used to return memory once the caller is finished with it. +After adjusting +.Fa size +the the value +.Va new_size +as mentioned in the +.Sx INTERNALS +subsection, above, the block is placed at the head of the free list of +.Va new_size Ns -sized +blocks. +If the given +.Fa size +is zero or negative, then +.Va errno +is set to +.Dv EINVAL , +as for +.Fn memget . +If +.Fa size +is larger than or equal to the pre-defined maximum size +.Dv MEM_FREECOUNT , +then the block is immediately +.Xr free 3 Ns No -d . +.Pp +.Sy NOTE : +It is important that callers give +.Fn memput +.Em only +blocks of memory which were previously obtained from +.Fn memget +if the block is +.Em actually +less than +.Dv SMALL_SIZE_LIMIT +bytes in size. Since all blocks will be added to a free list, any block +which is not at least +.Dv SMALL_SIZE_LIMIT +bytes long will not be able to hold a pointer to the next block in the +free list. +.Pp +The +.Fn memstats +function will summarize the number of calls to +.Fn memget +and +.Fn memput +for any block size from 1 byte up to +.Pq Dv MEM_FREECOUNT No - 1 +bytes, followed by a single line for any calls using a +.Fa size +greater than or equal to +.Dv MEM_FREECOUNT ; +a brief header with shell-style comment lines prefaces the report and +explains the information.

Each node +of the tree contains the expected left & right subtree pointers, a short int +balance indicator, and a pointer to the user data. On a 32 bit system, this +means an overhead of 4+4+2+4 bytes per node (or, on a RISC or otherwise +alignment constrained system with implied padding, 4+4+4+4 bytes per node). +There is no key data type enforced by this package; a caller supplied +compare routine is used to compare user data blocks. +.Pp +Balanced binary trees are very fast on searches and replacements, but have a +moderately high cost for additions and deletions. If your application does a +lot more searches and replacements than it does additions and deletions, the +balanced (AVL) binary tree is a good choice for a data structure. +.Pp +.Fn Tree_init +creates an empty tree and binds it to +.Dq Fa tree +(which for this and all other routines in this package should be declared as +a pointer to void or int, and passed by reference), which can then be used by +other routines in this package. Note that more than one +.Dq Fa tree +variable can exist at once; thus multiple trees can be manipulated +simultaneously. +.Pp +.Fn Tree_srch +searches a tree for a specific node and returns either +.Fa NULL +if no node was found, or the value of the user data pointer if the node +was found. +.Fn compare +is the address of a function to compare two user data blocks. This routine +should work much the way +.Xr strcmp 3 +does; in fact, +.Xr strcmp +could be used if the user data was a \s-2NUL\s+2 terminated string. +.Dq Fa Data +is the address of a user data block to be used by +.Fn compare +as the search criteria. The tree is searched for a node where +.Fn compare +returns 0. +.Pp +.Fn Tree_add +inserts or replaces a node in the specified tree. The tree specified by +.Dq Fa tree +is searched as in +.Fn tree_srch , +and if a node is found to match +.Dq Fa data , +then the +.Fn del_uar +function, if non\-\s-2NULL\s+2, is called with the address of the user data +block for the node (this routine should deallocate any dynamic memory which +is referenced exclusively by the node); the user data pointer for the node +is then replaced by the value of +.Dq Fa data . +If no node is found to match, a new node is added (which may or may not +cause a transparent rebalance operation), with a user data pointer equal to +.Dq Fa data . +A rebalance may or may not occur, depending on where the node is added +and what the rest of the tree looks like. +.Fn Tree_add +will return the +.Dq Fa data +pointer unless catastrophe occurs in which case it will return \s-2NULL\s+2. +.Pp +.Fn Tree_delete +deletes a node from +.Dq Fa tree . +A rebalance may or may not occur, depending on where the node is removed from +and what the rest of the tree looks like. +.Fn Tree_delete +returns TRUE if a node was deleted, FALSE otherwise. +.Pp +.Fn Tree_trav +traverses all of +.Dq Fa tree , +calling +.Fn trav_uar +with the address of each user data block. If +.Fn trav_uar +returns FALSE at any time, +.Fn tree_trav +will immediately return FALSE to its caller. Otherwise all nodes will be +reached and +.Fn tree_trav +will return TRUE. +.Pp +.Fn Tree_mung +deletes every node in +.Dq Fa tree , +calling +.Fn del_uar +(if it is not \s-2NULL\s+2) with the user data address from each node (see +.Fn tree_add +and +.Fn tree_delete +above). The tree is left in the same state that +.Fn tree_init +leaves it in \- i.e., empty. +.Sh BUGS +Should have a way for the caller to specify application-specific +.Xr malloc +and +.Xr free +functions to be used internally when allocating meta data. +.Sh AUTHOR +Paul Vixie, converted and augumented from Modula\-2 examples in +.Dq Algorithms & Data Structures , +Niklaus Wirth, Prentice\-Hall, ISBN 0\-13\-022005\-1. diff --git a/lib/bind/make/includes.in b/lib/bind/make/includes.in new file mode 100644 index 0000000..d7e21cb --- /dev/null +++ b/lib/bind/make/includes.in @@ -0,0 +1,44 @@ +# Copyright (C) 2004 Internet Systems Consortium, Inc.
