+.Dt KQUEUE 2 +.Os +.Sh NAME +.Nm kqueue , +.Nm kevent +.Nd kernel event notification mechanism +.Sh LIBRARY +.Lb libc +.Sh SYNOPSIS +.In sys/types.h +.In sys/event.h +.In sys/time.h +.Ft int +.Fn kqueue "void" +.Ft int +.Fn kevent "int kq" "const struct kevent *changelist" "int nchanges" "struct kevent *eventlist" "int nevents" "const struct timespec *timeout" +.Fn EV_SET "&kev" ident filter flags fflags data udata +.Sh DESCRIPTION +The +.Fn kqueue +system call +provides a generic method of notifying the user when an event +happens or a condition holds, based on the results of small +pieces of kernel code termed filters. +A kevent is identified by the (ident, filter) pair; there may only +be one unique kevent per kqueue. +.Pp +The filter is executed upon the initial registration of a kevent +in order to detect whether a preexisting condition is present, and is also +executed whenever an event is passed to the filter for evaluation. +If the filter determines that the condition should be reported, +then the kevent is placed on the kqueue for the user to retrieve. +.Pp +The filter is also run when the user attempts to retrieve the kevent +from the kqueue. +If the filter indicates that the condition that triggered +the event no longer holds, the kevent is removed from the kqueue and +is not returned. +.Pp +Multiple events which trigger the filter do not result in multiple +kevents being placed on the kqueue; instead, the filter will aggregate +the events into a single struct kevent. +Calling +.Fn close +on a file descriptor will remove any kevents that reference the descriptor. +.Pp +The +.Fn kqueue +system call +creates a new kernel event queue and returns a descriptor. +The queue is not inherited by a child created with +.Xr fork 2 . +However, if +.Xr rfork 2 +is called without the +.Dv RFFDG +flag, then the descriptor table is shared, +which will allow sharing of the kqueue between two processes. +.Pp +The +.Fn kevent +system call +is used to register events with the queue, and return any pending +events to the user. +The +.Fa changelist +argument +is a pointer to an array of +.Va kevent +structures, as defined in +.In sys/event.h . +All changes contained in the +.Fa changelist +are applied before any pending events are read from the queue. +The +.Fa nchanges +argument +gives the size of +.Fa changelist . +The +.Fa eventlist +argument +is a pointer to an array of kevent structures. +The +.Fa nevents +argument +determines the size of +.Fa eventlist . +When +.Fa nevents +is zero, +.Fn kevent +will return immediately even if there is a +.Fa timeout +specified unlike +.Xr select 2 . +If +.Fa timeout +is a non-NULL pointer, it specifies a maximum interval to wait +for an event, which will be interpreted as a struct timespec. +If +.Fa timeout +is a NULL pointer, +.Fn kevent +waits indefinitely. +To effect a poll, the +.Fa timeout +argument should be non-NULL, pointing to a zero-valued +.Va timespec +structure. +The same array may be used for the +.Fa changelist +and +.Fa eventlist . +.Pp +The +.Fn EV_SET +macro is provided for ease of initializing a +kevent structure. +.Pp +The +.Va kevent +structure is defined as: +.Bd -literal +struct kevent { + uintptr_t ident; /* identifier for this event */ + short filter; /* filter for event */ + u_short flags; /* action flags for kqueue */ + u_int fflags; /* filter flag value */ + intptr_t data; /* filter data value */ + void *udata; /* opaque user data identifier */ +}; +.Ed +.Pp +The fields of +.Fa struct kevent +are: +.Bl -tag -width XXXfilter +.It ident +Value used to identify this event. +The exact interpretation is determined by the attached filter, +but often is a file descriptor. +.It filter +Identifies the kernel filter used to process this event. +The pre-defined +system filters are described below. +.It flags +Actions to perform on the event. +.It fflags +Filter-specific flags. +.It data +Filter-specific data value. +.It udata +Opaque user-defined value passed through the kernel unchanged. +.El +.Pp +The +.Va flags +field can contain the following values: +.Bl -tag -width XXXEV_ONESHOT +.It EV_ADD +Adds the event to the kqueue. +Re-adding an existing event +will modify the parameters of the original event, and not result +in a duplicate entry. +Adding an event automatically enables it, +unless overridden by the EV_DISABLE flag. +.It EV_ENABLE +Permit +.Fn kevent +to return the event if it is triggered. +.It EV_DISABLE +Disable the event so +.Fn kevent +will not return it. +The filter itself is not disabled. +.It EV_DISPATCH +Disable the event source immediately after delivery of an event. +See +.Dv EV_DISABLE +above. +.It EV_DELETE +Removes the event from the kqueue. +Events which are attached to +file descriptors are automatically deleted on the last close of +the descriptor. +.It EV_RECEIPT +This flag is useful for making bulk changes to a kqueue without draining +any pending events. +When passed as input, it forces +.Dv EV_ERROR +to always be returned. +When a filter is successfully added the +.Va data +field will be zero. +.It EV_ONESHOT +Causes the event to return only the first occurrence of the filter +being triggered. +After the user retrieves the event from the kqueue, +it is deleted. +.It EV_CLEAR +After the event is retrieved by the user, its state is reset. +This is useful for filters which report state transitions +instead of the current state. +Note that some filters may automatically +set this flag internally. +.It EV_EOF +Filters may set this flag to indicate filter-specific EOF condition. +.It EV_ERROR +See +.Sx RETURN VALUES +below. +.El +.Pp +The predefined system filters are listed below. +Arguments may be passed to and from the filter via the +.Va fflags +and +.Va data +fields in the kevent structure. +.Bl -tag -width EVFILT_SIGNAL +.It EVFILT_READ +Takes a descriptor as the identifier, and returns whenever +there is data available to read. +The behavior of the filter is slightly different depending +on the descriptor type. +.Pp +.Bl -tag -width 2n +.It Sockets +Sockets which have previously been passed to +.Fn listen +return when there is an incoming connection pending. +.Va data +contains the size of the listen backlog. +.Pp +Other socket descriptors return when there is data to be read, +subject to the +.Dv SO_RCVLOWAT +value of the socket buffer. +This may be overridden with a per-filter low water mark at the +time the filter is added by setting the +NOTE_LOWAT +flag in +.Va fflags , +and specifying the new low water mark in +.Va data . +On return, +.Va data +contains the number of bytes of protocol data available to read. +.Pp +If the read direction of the socket has shutdown, then the filter +also sets EV_EOF in +.Va flags , +and returns the socket error (if any) in +.Va fflags . +It is possible for EOF to be returned (indicating the connection is gone) +while there is still data pending in the socket buffer. +.It Vnodes +Returns when the file pointer is not at the end of file. +.Va data +contains the offset from current position to end of file, +and may be negative. +.It "Fifos, Pipes" +Returns when the there is data to read; +.Va data +contains the number of bytes available. +.Pp +When the last writer disconnects, the filter will set EV_EOF in +.Va flags . +This may be cleared by passing in EV_CLEAR, at which point the +filter will resume waiting for data to become available before +returning. +.It "BPF devices" +Returns when the BPF buffer is full, the BPF timeout has expired, or +when the BPF has +.Dq immediate mode +enabled and there is any data to read; +.Va data +contains the number of bytes available. +.El +.It EVFILT_WRITE +Takes a descriptor as the identifier, and returns whenever +it is possible to write to the descriptor. +For sockets, pipes +and fifos, +.Va data +will contain the amount of space remaining in the write buffer. +The filter will set EV_EOF when the reader disconnects, and for +the fifo case, this may be cleared by use of EV_CLEAR. +Note that this filter is not supported for vnodes or BPF devices. +.Pp +For sockets, the low water mark and socket error handling is +identical to the EVFILT_READ case. +.It EVFILT_AIO +The sigevent portion of the AIO request is filled in, with +.Va sigev_notify_kqueue +containing the descriptor of the kqueue that the event should +be attached to, +.Va sigev_value +containing the udata value, and +.Va sigev_notify +set to SIGEV_KEVENT. +When the +.Fn aio_* +system call is made, the event will be registered +with the specified kqueue, and the +.Va ident +argument set to the +.Fa struct aiocb +returned by the +.Fn aio_* +system call. +The filter returns under the same conditions as aio_error. +.It EVFILT_VNODE +Takes a file descriptor as the identifier and the events to watch for in +.Va fflags , +and returns when one or more of the requested events occurs on the descriptor. +The events to monitor are: +.Bl -tag -width XXNOTE_RENAME +.It NOTE_DELETE +The +.Fn unlink +system call +was called on the file referenced by the descriptor. +.It NOTE_WRITE +A write occurred on the file referenced by the descriptor. +.It NOTE_EXTEND +The file referenced by the descriptor was extended. +.It NOTE_ATTRIB +The file referenced by the descriptor had its attributes changed. +.It NOTE_LINK +The link count on the file changed. +.It NOTE_RENAME +The file referenced by the descriptor was renamed. +.It NOTE_REVOKE +Access to the file was revoked via +.Xr revoke 2 +or the underlying file system was unmounted. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It EVFILT_PROC +Takes the process ID to monitor as the identifier and the events to watch for +in +.Va fflags , +and returns when the process performs one or more of the requested events. +If a process can normally see another process, it can attach an event to it. +The events to monitor are: +.Bl -tag -width XXNOTE_TRACKERR +.It NOTE_EXIT +The process has exited. +The exit status will be stored in +.Va data . +.It NOTE_FORK +The process has called +.Fn fork . +.It NOTE_EXEC +The process has executed a new process via +.Xr execve 2 +or similar call. +.It NOTE_TRACK +Follow a process across +.Fn fork +calls. +The parent process will return with NOTE_TRACK set in the +.Va fflags +field, while the child process will return with NOTE_CHILD set in +.Va fflags +and the parent PID in +.Va data . +.It NOTE_TRACKERR +This flag is returned if the system was unable to attach an event to +the child process, usually due to resource limitations. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It EVFILT_SIGNAL +Takes the signal number to monitor as the identifier and returns +when the given signal is delivered to the process. +This coexists with the +.Fn signal +and +.Fn sigaction +facilities, and has a lower precedence. +The filter will record +all attempts to deliver a signal to a process, even if the signal has +been marked as SIG_IGN. +Event notification happens after normal +signal delivery processing. +.Va data +returns the number of times the signal has occurred since the last call to +.Fn kevent . +This filter automatically sets the EV_CLEAR flag internally. +.It EVFILT_TIMER +Establishes an arbitrary timer identified by +.Va ident . +When adding a timer, +.Va data +specifies the timeout period in milliseconds. +The timer will be periodic unless EV_ONESHOT is specified. +On return, +.Va data +contains the number of times the timeout has expired since the last call to +.Fn kevent . +This filter automatically sets the EV_CLEAR flag internally. +There is a system wide limit on the number of timers +which is controlled by the +.Va kern.kq_calloutmax +sysctl. +.It Dv EVFILT_NETDEV +Takes a descriptor to a network interface as the identifier, and the events to watch for in +.Va fflags . +It returns, when one or more of the requested events occur on the descriptor. +The events to monitor are: +.Bl -tag -width XXNOTE_LINKDOWN +.It Dv NOTE_LINKUP +The link is up. +.It Dv NOTE_LINKDOWN +The link is down. +.It Dv NOTE_LINKINV +The link state is invalid. +.El +.Pp +On return, +.Va fflags +contains the events which triggered the filter. +.It Dv EVFILT_USER +Establishes a user event identified by +.Va ident +which is not assosicated with any kernel mechanism but is triggered by +user level code. +The lower 24 bits of the +.Va fflags +may be used for user defined flags and manipulated using the following: +.Bl -tag -width XXNOTE_FFLAGSMASK +.It Dv NOTE_FFNOP +Ignore the input +.Va fflags . +.It Dv NOTE_FFAND +Bitwise AND +.Va fflags . +.It Dv NOTE_FFOR +Bitwise OR +.Va fflags . +.It Dv NOTE_COPY +Copy +.Va fflags . +.It Dv NOTE_FFCTRLMASK +Control mask for +.Va fflags . +.It Dv NOTE_FFLAGSMASK +User defined flag mask for +.Va fflags . +.El +.Pp +A user event is triggered for output with the following: +.Bl -tag -width XXNOTE_FFLAGSMASK +.It Dv NOTE_TRIGGER +Cause the event to be triggered. +.El +.Pp +On return, +.Va fflags +contains the users defined flags in the lower 24 bits. +.El +.Sh RETURN VALUES +The +.Fn kqueue +system call +creates a new kernel event queue and returns a file descriptor. +If there was an error creating the kernel event queue, a value of -1 is +returned and errno set. +.Pp +The +.Fn kevent +system call +returns the number of events placed in the +.Fa eventlist , +up to the value given by +.Fa nevents . +If an error occurs while processing an element of the +.Fa changelist +and there is enough room in the +.Fa eventlist , +then the event will be placed in the +.Fa eventlist +with +.Dv EV_ERROR +set in +.Va flags +and the system error in +.Va data . +Otherwise, +.Dv -1 +will be returned, and +.Dv errno +will be set to indicate the error condition. +If the time limit expires, then +.Fn kevent +returns 0. +.Sh ERRORS +The +.Fn kqueue +system call fails if: +.Bl -tag -width

Status

 The current implementation status is here.
+

+There are several compatibility issues to be aware of when using this library under Linux:

+
    
+
+
  1. The NOTE_LOWAT flag is not supported. According to socket(7),
    
+
    +"The select(2) and poll(2) system  calls  currently  do not respect the 
+SO_RCVLOWAT setting on Linux, and mark a socket readable when even  a  
+single  byte  of data is available.  A subsequent read from the socket 
+will block until SO_RCVLOWAT bytes are available."
    
+
    2.

    Usage
    
+
+Assuming that libkqueue is installed under /usr/include:
+
+
      
+
    1. Add -I/usr/lib/kqueue to the CFLAGS variable.
+
    2. Add #include <sys/event.h> to the source code.
+
    3. Link against the libkqueue library by appending -lkqueue for single-threaded programs, or -lkqueue_r for multi-threaded programs.
+
    
+
+One major difference between libkqueue and the real kqueue is that 
+closing the kqueue descriptor will not free any of the resources
+associated with the descriptor. The following example shows how to
+close the descriptor and free the resources:
+
    
+
    +    int kqfd;
+
+    kqfd = kqueue();
+
+    /* ... */
+
+    close(kqfd);
+    #if LIBKQUEUE
+    kqueue_free(kqfd);
+    #endif
+
    
+
+If your program accesses an event queue from multiple threads,
+you should link against the threadsafe version of the library (libkqueue_r).
+This will provide reentrant versions of kqueue() and kevent().

      Usage

      libkqueue is a multi-threaded library and kqueue() and kevent() are safe to be used from multiple threads. -Assuming that libkqueue is installed under /usr/include: - +Here are the steps to use libkqueue in your program:
        -
      1. Add -I/usr/lib/kqueue to the CFLAGS variable. +
      2. Add `pkg-config libkqueue --cflags` to the CFLAGS variable. +
      3. Add `pkg-config libkqueue --libs` to the LDADD variable.
      4. Add #include <sys/event.h> to the source code. -
      5. Link against the libkqueue library by adding -lkqueue to the LDADD variable.
      One major difference between libkqueue and the real kqueue is that From 131285197d4e1ee62ce784d6ecd25e5e7954d77a Mon Sep 17 00:00:00 2001 From: mheily Date: Sun, 1 Nov 2009 23:49:32 +0000 Subject: [PATCH 0032/1120] docfix git-svn-id: svn://svn.code.sf.net/p/libkqueue/code/trunk@32 fb4e3144-bc1c-4b72-a658-5bcd248dd7f7 --- vendor/libkqueue/configure | 2 ++ 1 file changed, 2 insertions(+) diff --git a/vendor/libkqueue/configure b/vendor/libkqueue/configure index f8aed75f3..bbd24ca81 100755 --- a/vendor/libkqueue/configure +++ b/vendor/libkqueue/configure @@ -87,3 +87,5 @@ sed -e " s,@@MANDIR@@,$mandir,g;

        Status

      1. -The NOTE_EXTEND flag for the EVFILT_VNODE filter is not supported. An alternative approach is to use a combination of stat(2) and NOTE_ATTRIB to keep track of changes to the file's st_size field. -

      2. -The NOTE_LINK flag for the EVFILT_VNODE filter is not supported. An alternative approach is to use a combination of stat(2) and NOTE_ATTRIB to keep track of changes to the file's st_nlink field. -
        3. - -
      3. The NOTE_DELETE flag is supported; however, the event will not be triggered if the program holds an open file descriptor to the file being monitored. This behavior isn't documented in any Linux manpage; see here for discussion. A workaround would be to close the file descriptor after setting the NOTE_DELETE watch. +When an EVFILT_SIGNAL event is generated, the data field +is set to 1 regardless of how many times the signal was received by the process.

              Threads

              -libkqueue is a threadsafe library, and kqueue() and kevent() are safe to be used from multiple threads. libkqueue requires that the POSIX threads headers (pthread.h) be available, but does not require you to link against libpthread.so. This allows it to be used in both non-threaded and multi-threaded programs. +libkqueue uses one or more helper threads, so all programs that link with libkqueue must also link against the pthreads library. Calls to kqueue() and kevent() are safe to be used from multiple threads.

          +

          Portability of kevent(2) across BSD systems

          + +There are some differences in the behavior of the kevent(2) system call across the various BSD-based operating systems. Here are some of the differences to be aware of: + +
            + +
          1. FreeBSD 8 does not set the EV_ADD flag for kevents on the eventlist, but OpenBSD and Darwin do. This means you should never use the equality operator (==) to test the flags; use the logical AND operator instead. +
            2. + +
          2. The EVFILT_USER filter behaves differently from other filters with respect to the EV_ONESHOT flag. All other filters will preserve the flag when the event is triggered and placed on the eventlist. The EVFILT_USER filter does not preserve this flag. +
            3. + +
          3. +OpenBSD has the NOTE_TRUNCATE fflag, while FreeBSD and Darwin do not. +
            4. + + + +
          + +

        -
      • GCC -
      • Linux 2.6.22 or higher -
      • glibc 2.8 or higher -

      Usage

      - - -

      Ordinary Makefile

      - -Here are the steps to use libkqueue in your program if you use an ordinary Makefile: - -
        -
      1. Add `pkg-config libkqueue --cflags` to the CFLAGS variable. -
      2. Add `pkg-config libkqueue --libs` to the LDADD variable. -
      3. Add #include <sys/event.h> to the source code. -
      -

      - -

      Autoconf/Automake/Libtool

      - -If your program uses the GNU Autoconf/Automake/Libtool build system, the following steps will allow you to use libkqueue: - -
        - -
      1. Add the following to configure.ac: -
        -#
-# Prefer native kqueue(2); otherwise use libkqueue if present.
-#
-AC_CHECK_HEADER(sys/event.h, [],
-  [PKG_CHECK_MODULES(KQUEUE, libkqueue)]
-)
-
        -
        2. - -
      2. -Add the following to Makefile.am (assuming your program is named "foo"): -
        -foo_CFLAGS+=$(KQUEUE_CFLAGS)
-foo_LDADD+=$(KQUEUE_LIBS)
-
        -
        3. -
      - -

      Instead of using the $(KQUEUE_LIBS) variable, you could just add libkqueue.la to your programs LDADD variable. - -

      Threads

      - -libkqueue uses one or more helper threads, so all programs that link with libkqueue must also link against the pthreads library. Calls to kqueue() and kevent() are safe to be used from multiple threads. - - -

      Overview

      +libkqueue is a userspace implementation of the kqueue(2) kernel event notification mechanism. Initial efforts are focused on porting to the Linux 2.6 kernel. There is also an experimental Solaris port. + +

      +libkqueue acts as a translator between the kevent structure and the native kernel facilities of the host machine. The following diagram illustrates how this works under Linux: +

      + +

      + +

      + +Solaris has an event ports facility that is very similar to kqueue. On this platform, the kevent() function is mapped directly to the port_get() system call: + +

      + +

      + +

      Benchmarks

      +On Linux, libkqueue provides O(1) scalability relative to the number of concurrent client connections. This is an improvement over the traditional poll(2) system call which has O(N) scalability. For testing, two versions of the thttpd web server were compiled: one using libkqueue, and one using poll(2). The ApacheBench benchmarking utility was used to compare the performance of both versions. A custom script was used to create thousands of idle connections to the server, to simulate the use of HTTP Keepalives on a busy real-world server. +

      Usage

      + +Here are some issues to be aware of when using this library under any platform:
      + +
        + +
      1. +The EVFILT_PROC filter is not implemented. +
        2. + +
      2. +The EVFILT_AIO filter is not implemented. +
        3. + +
      3. When a kqueue descriptor is closed, it's resources are not immediately reclaimed. Instead, they will be freed the next time that the kqueue(2) function is called. +
        4. + +
      4. +A signal handler is implicitly installed when a EVFILT_SIGNAL kevent is created. For compatibility with kernel-based kqueue(2), programs must ignore signals that will generate kevents. After an EVFILT_SIGNAL kevent is created, a program must not modify the disposition of the associated signal. The following example shows the proper way to handle SIGUSR1 with a kevent:

        +

        +int main() {
+  int kqfd;
+  struct kevent kev;
+
+  kqfd = kqueue();
+  signal(SIGUSR1, SIG_IGN);
+  EV_SET(&kev, SIGUSR1, EVFILT_SIGNAL, EV_ADD, 0, 0, NULL);
+  kevent(kqfd, &kev, 1, NULL, 0, NULL);
+}
+
        +
      + +

      Linux

      + +There are several compatibility issues to be aware of when using this library under Linux:
      + +
        + +
      1. The NOTE_LOWAT flag is not supported. According to socket(7),
        +
        +"The select(2) and poll(2) system  calls  currently  do not respect the 
+SO_RCVLOWAT setting on Linux, and mark a socket readable when even  a  
+single  byte  of data is available.  A subsequent read from the socket 
+will block until SO_RCVLOWAT bytes are available."
        +
        2. + +
      2. +The NOTE_REVOKE flag is not supported because Linux does not have +a revoke(2) system call. +
        3. + +
      3. +When an EVFILT_SIGNAL event is generated, the data field +is set to 1 regardless of how many times the signal was received by the process. +
        4. + +
      4. +When an EVFILT_READ event occurs on a listening socket, the data field is set to 1 regardless of how many pending connections are available. + + + +
      + +

      Solaris

      +Here are the issues to be aware of when using this library under Solaris:
      + +
        + +
      1. +Solaris 10 or newer is required. It should work with OpenSolaris and other Solaris-based distributions, but has not been tested. +
        2. + +
      2. +The EVFILT_VNODE filter is not implemented. This will eventually be implemented +using the PORT_SOURCE_FILE mechanism described here. +
        3. + +
      3. The EVFILT_TIMER filter is implemented using high-resolution timers. In order to use high-resolution timers, the calling process must hold the PRIV_PROC_CLOCK_HIGHRES privilege. This privilege is not granted to ordinary users by default. It can be granted to individual users by running the following command as root:
        +
        +# usermod -K defaultpriv=basic,proc_clock_highres $user
+
        +
      + +

      BSD-based systems

      + +There are some differences in the behavior of the kevent(2) system call across the various BSD-based operating systems. Here are some of the differences to be aware of: + +
        + +
      1. FreeBSD 8 does not set the EV_ADD flag for kevents on the eventlist, but OpenBSD and Darwin do. This means you should never use the equality operator (==) to test the flags; use the logical AND operator instead. +
        2. + +
      2. The EVFILT_USER filter behaves differently from other filters with respect to the EV_ONESHOT flag. All other filters will preserve the flag when the event is triggered and placed on the eventlist. The EVFILT_USER filter does not preserve this flag. +
        3. + +
      3. +OpenBSD has the NOTE_TRUNCATE fflag, while FreeBSD and Darwin do not. +
        4. + +
      4. +EVFILT_FS is undocumented and only available on FreeBSD and Darwin. Here is the CVS commit log which could be helpful to document this filter. +
        5. + + +
      + +

      Integration

      + +

      Ordinary Makefile

      + +Here are the steps to use libkqueue in your program if you use an ordinary Makefile: + +
        +
      1. Add ‘pkg-config libkqueue --cflags‘ to the CFLAGS variable. +
      2. Add ‘pkg-config libkqueue --libs‘ to the LDADD variable. +
      3. Add #include <sys/event.h> to the source code. +
      +

      + +

      Autoconf/Automake/Libtool

      + +If your program uses the GNU Autoconf/Automake/Libtool build system, the following steps will allow you to use libkqueue: + +
        + +
      1. Add the following to configure.ac: +
        +#
+# Prefer native kqueue(2); otherwise use libkqueue if present.
+#
+AC_CHECK_HEADER(sys/event.h, [],
+  [PKG_CHECK_MODULES(KQUEUE, libkqueue)]
+)
+
        +
        2. + +
      2. +Add the following to Makefile.am (assuming your program is named "foo"): +
        +foo_CFLAGS+=$(KQUEUE_CFLAGS)
+foo_LDADD+=$(KQUEUE_LIBS)
+
        +
        3. +
      + +

      Instead of using the $(KQUEUE_LIBS) variable, you could just add libkqueue.la to your programs LDADD variable. + +

Initial efforts are focused on porting to the Linux 2.6 kernel. There is also an experimental Solaris port.

      libkqueue acts as a translator between the kevent structure and the native kernel facilities of the host machine. The following diagram illustrates how this works under Linux:

      - +Linux implementation

      Solaris has an event ports facility that is very similar to kqueue. On this platform, the kevent() function is mapped directly to the port_get() system call:

      - +Solaris implementation

      Benchmarks

      On Linux, libkqueue provides O(1) scalability relative to the number of concurrent client connections. This is an improvement over the traditional poll(2) system call which has O(N) scalability. For testing, two versions of the thttpd web server were compiled: one using libkqueue, and one using poll(2). The ApacheBench benchmarking utility was used to compare the performance of both versions. A custom script was used to create thousands of idle connections to the server, to simulate the use of HTTP Keepalives on a busy real-world server.

Add reference counting to the knote structure. This is slightly buggy and probably unnecessary. Eliminate the kqueue_lock() and kqueue_unlock() functions, and create a heirarchy of two locks: the knotelist lock at the filter level, and a per-knote lock. This needs to be looked at more closely. Make note of a race condition when kev.flags contains EV_ADD | EV_DISABLE and a new knote is created. git-svn-id: svn://svn.code.sf.net/p/libkqueue/code/trunk@411 fb4e3144-bc1c-4b72-a658-5bcd248dd7f7 --- vendor/libkqueue/src/common/filter.c | 1 + vendor/libkqueue/src/common/kevent.c | 108 +++++++++++--------------- vendor/libkqueue/src/common/knote.c | 47 +++++++++-- vendor/libkqueue/src/common/private.h | 14 ++-- vendor/libkqueue/src/linux/platform.c | 8 +- vendor/libkqueue/src/linux/user.c | 1 + 6 files changed, 100 insertions(+), 79 deletions(-) diff --git a/vendor/libkqueue/src/common/filter.c b/vendor/libkqueue/src/common/filter.c index 8724baf4a..18461a647 100644 --- a/vendor/libkqueue/src/common/filter.c +++ b/vendor/libkqueue/src/common/filter.c @@ -46,6 +46,7 @@ filter_register(struct kqueue *kq, short filter, const struct filter *src) memcpy(dst, src, sizeof(*src));

This is controlled by the SERIALIZE_KEVENT macro. This temporarily restores the behavior from libkqueue 1.0 to give us time to implement fine-grained locking properly.

      Overview

      -libkqueue is a userspace implementation of the kqueue(2) kernel event notification mechanism. Initial efforts are focused on porting to the Linux 2.6 kernel. There is also an experimental Solaris port. - -

      -libkqueue acts as a translator between the kevent structure and the native kernel facilities of the host machine. The following diagram illustrates how this works under Linux: -

      - -

      -Linux implementation -

      - -Solaris has an event ports facility that is very similar to kqueue. On this platform, the kevent() function is mapped directly to the port_get() system call: - -

      -Solaris implementation -

      - -

      Benchmarks

      -On Linux, libkqueue provides O(1) scalability relative to the number of concurrent client connections. This is an improvement over the traditional poll(2) system call which has O(N) scalability. For testing, two versions of the thttpd web server were compiled: one using libkqueue, and one using poll(2). The ApacheBench benchmarking utility was used to compare the performance of both versions. A custom script was used to create thousands of idle connections to the server, to simulate the use of HTTP Keepalives on a busy real-world server. -

      Usage

      - -Here are some issues to be aware of when using this library under any platform: -
      - -
        - -
      1. -The EVFILT_PROC filter is not implemented. -
        2. - -
      2. -The EVFILT_AIO filter is not implemented. -
        3. - -
      3. When a kqueue descriptor is closed, it's resources are not immediately reclaimed. Instead, they will be freed the next time that the kqueue(2) function is called. -
        4. - -
      4. -A signal handler is implicitly installed when a EVFILT_SIGNAL kevent is created. For compatibility with kernel-based kqueue(2), programs must ignore signals that will generate kevents. After an EVFILT_SIGNAL kevent is created, a program must not modify the disposition of the associated signal. The following example shows the proper way to handle SIGUSR1 with a kevent: - -
        -int main() {
-  int kqfd;
-  struct kevent kev;
-
-  kqfd = kqueue();
-  signal(SIGUSR1, SIG_IGN);
-  EV_SET(&kev, SIGUSR1, EVFILT_SIGNAL, EV_ADD, 0, 0, NULL);
-  kevent(kqfd, &kev, 1, NULL, 0, NULL);
-}

      - -

      Linux

      - -There are several compatibility issues to be aware of when using this library under Linux:
      - -
        - -
      1. The NOTE_LOWAT flag is not supported. According to socket(7),
        -
        -"The select(2) and poll(2) system  calls  currently  do not respect the 
-SO_RCVLOWAT setting on Linux, and mark a socket readable when even  a  
-single  byte  of data is available.  A subsequent read from the socket 
-will block until SO_RCVLOWAT bytes are available."
        -
        2. - -
      2. -The NOTE_REVOKE flag is not supported because Linux does not have -a revoke(2) system call. -
        3. - -
      3. -When an EVFILT_SIGNAL event is generated, the data field -is set to 1 regardless of how many times the signal was received by the process. -
        4. - -
      4. -When an EVFILT_READ event occurs on a listening socket, the data field is set to 1 regardless of how many pending connections are available. - - - -
      - -

      Solaris

      - -Here are the issues to be aware of when using this library under Solaris:
      - -
        - -
      1. -Solaris 10 or newer is required. It should work with OpenSolaris and other Solaris-based distributions, but has not been tested. -
        2. - -
      2. -When an EVFILT_READ event is generated, the data field -is set to 1 regardless of how many bytes are available to read. -
        3. - -
      3. -When an EVFILT_TIMER event is generated, the data field -is set to 1 regardless of how many times the timer has been triggered. -
        4. - -
      4. -The EVFILT_VNODE filter is not implemented. This will eventually be implemented -using the PORT_SOURCE_FILE mechanism described here. -
        5. - -
      5. The EVFILT_TIMER filter is implemented using high-resolution timers. In order to use high-resolution timers, the calling process must hold the PRIV_PROC_CLOCK_HIGHRES privilege. This privilege is not granted to ordinary users by default. It can be granted to individual users by running the following command as root:
        -
        -# usermod -K defaultpriv=basic,proc_clock_highres $user
-
        -
      - -

      BSD-based systems

      - -There are some differences in the behavior of the kevent(2) system call across the various BSD-based operating systems. Here are some of the differences to be aware of: - -
        - -
      1. FreeBSD 8 does not set the EV_ADD flag for kevents on the eventlist, but OpenBSD and Darwin do. This means you should never use the equality operator (==) to test the flags; use the logical AND operator instead. -
        2. - -
      2. The EVFILT_USER filter behaves differently from other filters with respect to the EV_ONESHOT flag. All other filters will preserve the flag when the event is triggered and placed on the eventlist. The EVFILT_USER filter does not preserve this flag. -
        3. - -
      3. -OpenBSD has the NOTE_TRUNCATE fflag, while FreeBSD and Darwin do not. -
        4. - -
      4. -EVFILT_FS is undocumented and only available on FreeBSD and Darwin. Here is the CVS commit log which could be helpful to document this filter. -
        5. - - -
      - -

      Integration

      - -

      Ordinary Makefile

      - -Here are the steps to use libkqueue in your program if you use an ordinary Makefile: - -
        -
      1. Add ‘pkg-config libkqueue --cflags‘ to the CFLAGS variable. -
      2. Add ‘pkg-config libkqueue --libs‘ to the LDADD variable. -
      3. Add #include <sys/event.h> to the source code. -
      - -

      Autoconf/Automake/Libtool

      - -If your program uses the GNU Autoconf/Automake/Libtool build system, the following steps will allow you to use libkqueue: - -
        - -
      1. Add the following to configure.ac: -
        -#
-# Prefer native kqueue(2); otherwise use libkqueue if present.
-#
-AC_CHECK_HEADER(sys/event.h, [],
-  [PKG_CHECK_MODULES(KQUEUE, libkqueue)]
-)
-
        -
        2. - -
      2. -Add the following to Makefile.am (assuming your program is named "foo"): -
        -foo_CFLAGS+=$(KQUEUE_CFLAGS)
-foo_LDADD+=$(KQUEUE_LIBS)
-
        -
        3. -
      - -Instead of using the $(KQUEUE_LIBS) variable, you could just add libkqueue.la to your programs LDADD variable. - -

      Threads

      - -libkqueue uses one or more helper threads, so all programs that link with libkqueue must also link against the pthreads library. Calls to kqueue() and kevent() are safe to be used from multiple threads. - -m4_include(footer.m4) From 6a82981463e3ee5e19560219c288ce860ff85356 Mon Sep 17 00:00:00 2001 From: marius Date: Wed, 4 May 2011 17:39:25 +0000 Subject: [PATCH 0471/1120] Fixed some mistakes within the CMakeLists.txt Made latest revision compatible to windows again git-svn-id: svn://svn.code.sf.net/p/libkqueue/code/trunk@500 fb4e3144-bc1c-4b72-a658-5bcd248dd7f7 --- vendor/libkqueue/CMakeLists.txt | 7 ------- vendor/libkqueue/src/common/debug.h | 4 +++- vendor/libkqueue/test/CMakeLists.txt | 2 +- 3 files changed, 4 insertions(+), 9 deletions(-) diff --git a/vendor/libkqueue/CMakeLists.txt b/vendor/libkqueue/CMakeLists.txt index d81531306..92155bf8a 100644 --- a/vendor/libkqueue/CMakeLists.txt +++ b/vendor/libkqueue/CMakeLists.txt @@ -17,13 +17,6 @@ cmake_minimum_required(VERSION 2.8) INCLUDE (CheckIncludeFiles) -#tests -option(KQUEUE_TESTS "Enable to build tests for libkqueue" OFF) -if(KQUEUE_TESTS) - message("-- Adding tests for libkqueue") - add_subdirectory(test) -endif() - project(kqueue) #files diff --git a/vendor/libkqueue/src/common/debug.h b/vendor/libkqueue/src/common/debug.h index 9fbd1653c..e69ba32ad 100644 --- a/vendor/libkqueue/src/common/debug.h +++ b/vendor/libkqueue/src/common/debug.h @@ -19,7 +19,9 @@ #include #include -#include +#ifndef _WIN32 +# include +#endif extern int DEBUG_ACTIVE; extern char *DEBUG_IDENT; diff --git a/vendor/libkqueue/test/CMakeLists.txt b/vendor/libkqueue/test/CMakeLists.txt index 770650335..e09c4d754 100644 --- a/vendor/libkqueue/test/CMakeLists.txt +++ b/vendor/libkqueue/test/CMakeLists.txt @@ -56,5 +56,5 @@ else() endif() add_executable(libkqueue-test ${SRC}) -target_link_libraries(libkqueue-test libkqueue ${LIBS}) +target_link_libraries(libkqueue-test kqueue ${LIBS}) set_target_properties(libkqueue-test PROPERTIES DEBUG_POSTFIX "D") From 3d4f6b85b3292f6458241bbacb9e81daf2f23082 Mon Sep 17 00:00:00 2001 From: marius Date: Mon, 9 May 2011 19:04:31 +0000 Subject: [PATCH 0472/1120] Removed unused/unneeded evt_loop implementation git-svn-id: svn://svn.code.sf.net/p/libkqueue/code/trunk@501 fb4e3144-bc1c-4b72-a658-5bcd248dd7f7 --- vendor/libkqueue/src/windows/event_loop.c | 269 ---------------------- vendor/libkqueue/src/windows/event_loop.h | 119 ---------- vendor/libkqueue/src/windows/platform.c | 25 +- vendor/libkqueue/src/windows/platform.h | 2 - 4 files changed, 2 insertions(+), 413 deletions(-) delete mode 100644 vendor/libkqueue/src/windows/event_loop.c delete mode 100644 vendor/libkqueue/src/windows/event_loop.h diff --git a/vendor/libkqueue/src/windows/event_loop.c b/vendor/libkqueue/src/windows/event_loop.c deleted file mode 100644 index 64c2b088a..000000000 --- a/vendor/libkqueue/src/windows/event_loop.c +++ /dev/null @@ -1,269 +0,0 @@ -/* -* Copyright (c) 2011 Marius Zwicker -* -* Permission to use, copy, modify, and distribute this software for any -* purpose with or without fee is hereby granted, provided that the above -* copyright notice and this permission notice appear in all copies. -* -* THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES -* WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF -* MERCHANTABILITY AND FITNESS.

This pathname is null-terminated, and may include further null bytes ('\0') to align subsequent reads to a suitable address boundary. Without this patch, the abort is triggered after the loop exits. Removing the abort would cause misaligned reads, where the next time get_one_event was called, the structure would be populate with the name of the file from the previous event. --- vendor/libkqueue/src/linux/vnode.c | 71 ++++++++++++++++++------------ 1 file changed, 43 insertions(+), 28 deletions(-) diff --git a/vendor/libkqueue/src/linux/vnode.c b/vendor/libkqueue/src/linux/vnode.c index a02c505c5..e8a5d0eed 100644 --- a/vendor/libkqueue/src/linux/vnode.c +++ b/vendor/libkqueue/src/linux/vnode.c @@ -49,9 +49,15 @@ inotify_event_dump(struct inotify_event *evt) { static __thread char buf[1024];

However, this system call does not work for descriptors other than sockets, and it'd be a total waste of time to call it just to get ENOTSOCK. In order to avoid the cost of the context switch, let's store some additional information from the times the knote was created. This change mostly deals with the Linux code only; likely the same changes can be applied to Windows as well. However, this issue is to be addressed by a separate commit. --- vendor/libkqueue/src/common/kevent.c | 2 +- vendor/libkqueue/src/common/private.h | 17 ++-- vendor/libkqueue/src/linux/platform.c | 101 ++++++++++++++++++------ vendor/libkqueue/src/linux/read.c | 25 +++--- vendor/libkqueue/src/linux/write.c | 16 +++- vendor/libkqueue/src/windows/platform.c | 8 +- vendor/libkqueue/src/windows/read.c | 2 +- 7 files changed, 123 insertions(+), 48 deletions(-) diff --git a/vendor/libkqueue/src/common/kevent.c b/vendor/libkqueue/src/common/kevent.c index fe808f188..21bf23417 100644 --- a/vendor/libkqueue/src/common/kevent.c +++ b/vendor/libkqueue/src/common/kevent.c @@ -144,7 +144,7 @@ kevent_copyin_one(struct kqueue *kq, const struct kevent *src) memcpy(&kn->kev, src, sizeof(kn->kev)); kn->kev.flags &= ~EV_ENABLE; kn->kev.flags |= EV_ADD;//FIXME why? - kn->kn_kq = kq; + kn->kn_kq = kq; assert(filt->kn_create); if (filt->kn_create(filt, kn) < 0) { knote_release(kn); diff --git a/vendor/libkqueue/src/common/private.h b/vendor/libkqueue/src/common/private.h index 39ffe6749..89e2281c6 100644 --- a/vendor/libkqueue/src/common/private.h +++ b/vendor/libkqueue/src/common/private.h @@ -66,14 +66,21 @@ struct eventfd { /* * Flags used by knote->kn_flags */ -#define KNFL_PASSIVE_SOCKET (0x01) /* Socket is in listen(2) mode */ -#define KNFL_REGULAR_FILE (0x02) /* File descriptor is a regular file */ -#define KNFL_STREAM_SOCKET (0x03) /* File descriptor is a stream socket */ -#define KNFL_KNOTE_DELETED (0x10) /* The knote object is no longer valid */ +#define KNFL_FILE (1U << 0U) +#define KNFL_PIPE (1U << 1U) +#define KNFL_SOCKET (1U << 2U) +#define KNFL_BLOCKDEV (1U << 3U) +#define KNFL_CHARDEV (1U << 4U) +#define KNFL_SOCKET_PASSIVE (KNFL_SOCKET | (1U << 5U)) +#define KNFL_SOCKET_STREAM (KNFL_SOCKET | (1U << 6U)) +#define KNFL_SOCKET_DGRAM (KNFL_SOCKET | (1U << 7U)) +#define KNFL_SOCKET_RDM (KNFL_SOCKET | (1U << 8U)) +#define KNFL_SOCKET_SEQPACKET (KNFL_SOCKET | (1U << 9U)) +#define KNFL_KNOTE_DELETED (1U << 31U) struct knote { struct kevent kev; - int kn_flags; + unsigned int kn_flags; union { /* OLD */ int pfd; /* Used by timerfd */ diff --git a/vendor/libkqueue/src/linux/platform.c b/vendor/libkqueue/src/linux/platform.c index fec7655b0..7067933bd 100644 --- a/vendor/libkqueue/src/linux/platform.c +++ b/vendor/libkqueue/src/linux/platform.c @@ -552,32 +552,95 @@ linux_get_descriptor_type(struct knote *kn) { socklen_t slen; struct stat sb; - int i, lsock, stype; + int ret, lsock, stype; socklen_t out_len; + const int fd = (int)kn->kev.ident; /* - * Test if the descriptor is a socket. + * Determine the actual descriptor type. */ - if (fstat(kn->kev.ident, &sb) < 0) { + if (fstat(fd, &sb) < 0) { dbg_perror("fstat(2)"); return (-1); } - if (S_ISREG(sb.st_mode)) { - kn->kn_flags |= KNFL_REGULAR_FILE; - dbg_printf("fd %d is a regular file\n", (int)kn->kev.ident); - return (0); + switch (sb.st_mode & S_IFMT) { + case S_IFREG: + dbg_printf("fd %d is a regular file\n", fd); + kn->kn_flags |= KNFL_FILE; + break; + + case S_IFIFO: + dbg_printf("fd %d is a pipe\n", fd); + kn->kn_flags |= KNFL_PIPE; + break; + + case S_IFBLK: + dbg_printf("fd %d is a block device\n", fd); + kn->kn_flags |= KNFL_BLOCKDEV; + break; + + case S_IFCHR: + dbg_printf("fd %d is a character device\n", fd); + kn->kn_flags |= KNFL_CHARDEV; + break; + + case S_IFSOCK: + dbg_printf("fd %d is a socket\n", fd); + kn->kn_flags |= KNFL_SOCKET; + break; + + default: + errno = EBADF; + dbg_perror("unknown fd type"); + return -1; } /* * Test if the socket is active or passive. */ - if (!

CPack seems to have no concept of this, so puts the whole description, as-is, in the Description: field. This means that lines following a line-break don't start with a space. This spectacularly breaks component packages. Essentially a CPack bug, which should have a package Summary and a package Description and handle them correctly, but messing around with the format here will also affect the RPM packages because the debian-specific settings don't override the generic one.

Known limitations: - Need to verify correct behaviour of EV_DISPATCH when both filters are registered for events. This now needs to be implemented internally by libkqueue instead of relying on EPOLLET, as EPOLLET applies to both EPOLLIN and EPOLLOUT. - If the number of events we are to return does not have sufficient space for at least two entries when polling an FD registered for both read and write events, the write event will be lost. We can fix this by implementing a linked list of pending events we return before calling the platform's wait function. Will probably copy the dlist implementation from FreeRADIUS across, as it's been well tested, and is a header only implementation like the current rbtree. A dlist is needed to store entries for EVFILT_PROC anyway, which is the next filter that needs major attention. --- vendor/libkqueue/src/common/kevent.c | 4 +- vendor/libkqueue/src/common/private.h | 21 +- vendor/libkqueue/src/linux/platform.c | 543 ++++++++++++++++++++++---- vendor/libkqueue/src/linux/platform.h | 121 +++++- vendor/libkqueue/src/linux/read.c | 51 +-- vendor/libkqueue/src/linux/signal.c | 13 +- vendor/libkqueue/src/linux/timer.c | 11 +- vendor/libkqueue/src/linux/user.c | 7 +- vendor/libkqueue/src/linux/vnode.c | 7 +- vendor/libkqueue/src/linux/write.c | 37 +- 10 files changed, 645 insertions(+), 170 deletions(-) diff --git a/vendor/libkqueue/src/common/kevent.c b/vendor/libkqueue/src/common/kevent.c index 628155328..fa9bd5078 100644 --- a/vendor/libkqueue/src/common/kevent.c +++ b/vendor/libkqueue/src/common/kevent.c @@ -177,12 +177,12 @@ kevent_copyin_one(struct kqueue *kq, const struct kevent *src) rv = knote_delete(filt, kn); dbg_printf("knote_delete returned %d", rv); } else if (src->flags & EV_DISABLE) { - kn->kev.flags |= EV_DISABLE; rv = filt->kn_disable(filt, kn); + if (rv == 0) kn->kev.flags |= EV_DISABLE; dbg_printf("kn_disable returned %d", rv); } else if (src->flags & EV_ENABLE) { - kn->kev.flags &= ~EV_DISABLE; rv = filt->kn_enable(filt, kn); + if (rv == 0) kn->kev.flags &= ~EV_DISABLE; dbg_printf("kn_enable returned %d", rv); } else if (src->flags & EV_ADD || src->flags == 0 || src->flags & EV_RECEIPT) { kn->kev.udata = src->udata; diff --git a/vendor/libkqueue/src/common/private.h b/vendor/libkqueue/src/common/private.h index 668680a2f..0c2762a1f 100644 --- a/vendor/libkqueue/src/common/private.h +++ b/vendor/libkqueue/src/common/private.h @@ -139,7 +139,7 @@ struct knote { * */ struct filter { - short kf_id; //!< EVFILT_* facility this filter provides. + short kf_id; //!< EVFILT_* facility this filter provides. /* filter operations */ @@ -151,20 +151,19 @@ struct filter { int (*kn_create)(struct filter *, struct knote *); - int (*kn_modify)(struct filter *, struct knote *, - const struct kevent *); + int (*kn_modify)(struct filter *, struct knote *, const struct kevent *); int (*kn_delete)(struct filter *, struct knote *); int (*kn_enable)(struct filter *, struct knote *); int (*kn_disable)(struct filter *, struct knote *); - struct eventfd kf_efd; /* Used by user.c */ + struct eventfd kf_efd; //!< Used by user.c //MOVE TO POSIX? - int kf_pfd; /* fd to poll(2) for readiness */ - int kf_wfd; /* fd to write when an event occurs */ + int kf_pfd; //!< fd to poll(2) for readiness + int kf_wfd; //!< fd to write when an event occurs //----? - struct evfilt_data *kf_data; /* filter-specific data */ + struct evfilt_data *kf_data; //!< filter-specific data */ RB_HEAD(knt, knote) kf_knote; pthread_rwlock_t kf_knote_mtx; struct kqueue *kf_kqueue; @@ -182,10 +181,10 @@ struct filter { * in receiving notifications for. */ struct kqueue { - int kq_id; //!< File descriptor used to identify this kqueue. - struct filter kq_filt[EVFILT_SYSCOUNT]; //!< Filters supported by the kqueue.
