Version: 7.2.1-bp154.2.9.1
* Wed Nov 09 2022 Jan Engelhardt <>
- Update to release 7.2.1
  * Attempts to mark well-known headers like Content-Length and
    Host hop-by-hop through a Connection-header will now cause a
    400 "Bad request" response.
    (VSV00010, CVE-2022-45059, boo#1205243)
  * Apply the same character set rules to HTTP/2 pseudo-headers
    as is done on the corresponding HTTP/1 request-line field
    parsing. (VSV00011, CVE-2022-45060, boo#1205242)
* Sat Oct 29 2022 Dirk Müller <>
- update to 7.2.0:
  * Functions ``VRT_AddVDP()``, ``VRT_AddVFP()``,
    ``VRT_RemoveVDP()`` and ``VRT_RemoveVFP()`` are deprecated.
  * Cookie headers generated by vmod_cookie no longer have a
    spurious trailing semicolon at the end of the string. This
    could break VCL relying on the previous incorrect behavior.
  * The ``SessClose`` and ``BackendClose`` reason ``rx_body``,
    which previously output ``Failure receiving req.body``, has
    been rewritten to ``Failure receiving body``.
  * Prototypical Varnish Extensions (VEXT). Similar to VMODs, a
    VEXT is loaded by the cache process. Unlike VMODs that have
    the combined lifetime of all the VCLs that reference them, a
    VEXT has the lifetime of the cache process itself. There are
    no built-in extensions so far.
  * Duration parameters can optionally take a unit, with the same
    syntax as duration units in VCL.
  * Calls to ``VRT_CacheReqBody()`` and ``std.cache_req_body``
    from outside client vcl subs now fail properly instead of
    triggering an assertion failure.
  * New "B" string for the package branch in ``VCS_String()``.
    For the 7.2.0 version, it would yield the 7.2 branch.
  * The new ``vcc_feature`` bits parameter replaces previous
    ``vcc_*`` boolean parameters. The latter still exist as
    deprecated aliases.
  * The ``-k`` option from ``varnishlog`` is now supported by
  * New functions ```` and ``std.timed_call()`` in
  * New ``MAIN.shm_bytes`` counter.
  * A ``req.http.via`` header is set before entering
    ``vcl_recv``. Via headers are generated using the
    ``server.identity`` value. It defaults to the host name and
    can be turned into a pseudonym with the ``varnishd -i``
    option. Via headers are appended in both directions, to work
    with other hops that may advertise themselves.
  * A ``resp.http.via`` header is no longer overwritten by
    varnish, but rather appended to.
  * The ``server.identity`` syntax is now limited to a "token" as
    defined in the HTTP grammar to be suitable for Via headers.
  * In ``varnishtest`` a Varnish instance will use its VTC
    instance name as its instance name (``varnishd -i``) by
    default for predictable Via headers in test cases.
  * VMOD and VEXT authors can use functions from ``vnum.h``.
  * Do not filter pseudo-headers as regular headers.
  * The termination rules for ``WRK_BgThread()`` were relaxed to
    allow VMODs to use it.
  * ``(struct worker).handling`` has been moved to the newly
    introduced ``struct wrk_vpi`` and replaced by a pointer to
    it, as well as ``(struct vrt_ctx).handling`` has been
    replaced by that pointer. ``struct wrk_vpi`` is for state at
    the interface between VRT and VGC and, in particular, is not
    const as ``struct vrt_ctx`` aka ``VRT_CTX``.
  * Panics now contain information about VCL source files and
  * The ``Begin`` log record has a 4th field for subtasks like
    ESI sub-requests.
  * The ``-E`` option for log utilities now works as documented,
    with any type of sub-task based on the ``Begin[4]`` field.
    This covers ESI like before, and sub-tasks spawned by VMODs
    (provided that they log the new field).
  * No more ``req.http.transfer-encoding`` for ESI sub-requests.
  * The thread pool reserve is now limited to tasks that can be
    queued. A backend background fetch is no longer eligible for
    queueing. It would otherwise slow a grace hit down
    significantly when thread pools are saturated.
  * The unused ``fetch_no_thread`` counter was renamed to
    ``bgfetch_no_thread`` because regular backend fetch tasks are
    always scheduled.
  * The macros ``FEATURE()``, ``EXPERIMENT()``, ``DO_DEBUG()``,
    and ``MGT_VCC_FEATURE()`` now return a boolean value (``0``
    or ``1``) instead of the (private) flag value.
  * A regression in the transport code led MAIN.client_req to be
    incremented for requests coming back from the waiting list,
    it was fixed.

  * Fix an HTTP/2.0 request smuggling vulnerability. [bnc#1188470]
* Sun Jul 04 2021 Dirk Müller <>
- update to 6.6.0:
  * The ban_cutoff parameter now refers to the overall length of
    the ban list, including completed bans, where before only
    non-completed (“active”) bans were counted towards ban_cutoff.
  * Body bytes accounting has been fixed to always represent the
    number of body bytes moved on the wire, exclusive of
    protocol-specific overhead like HTTP/1 chunked encoding or
    HTTP/2 framing.
  * The connection close reason has been fixed to properly report
    SC_RESP_CLOSE where previously only SC_REQ_CLOSE was reported.
  * Unless the new validate_headers feature is disabled, all newly
    set headers are now validated to contain only characters
    allowed by RFC7230.
  * The filter_re, keep_re and get_re functions from the bundled
    cookie vmod have been changed to take the VCL_REGEX type. This
    implies that their regular expression arguments now need to be
    literal, not e.g. string.
  * The interface for private pointers in VMODs has been changed,
    the VRT backend interface has been changed, many filter
    (VDP/VFP) related signatures have been changed, and the

- Changes introduced by version 5.1.1:
  * Fix bug introduced by stubborn old bugger right before release
    5.1.0 was cut.
- Changes introduced by version 5.1.0:
  * Added varnishd command-line options -I, -x and -?, and
    tightened restrictions on permitted combinations of options.
  * More progress on support for HTTP/2.
  * Add ``return(fail)`` to almost all VCL subroutines.
  * Restored the old hit-for-pass, invoked with
    ``return(pass(DURATION))`` from
    ``vcl_backend_response``. hit-for-miss remains the default.
    Added the cache_hitmiss stat, and cache_hitpass only counts the
    new/old hit-for-pass cases. Restored HitPass to the Varnish
    log, and added HitMiss. Added the HFP prefix to TTL log entries
    to log a hit-for-pass duration.
  * Rolled back the fix for #1206. Client delivery decides solely
    whether to send a 304 client response, based on client request
    and response headers.
  * Added
  * Added vxid as a lefthand side for VSL queries.
  * Added the setenv and write_body commands for Varnish test cases
    (VTCs). err_shell is deprecated. Also added the operators
  - cliexpect, -match and -hdrlen, and -reason replaces -msg.
    Added the ${bad_backend} macro.
  * varnishtest can be stopped with the TERM, INT and KILL signals,
    but not with HUP.
  * The fallback director has now an extra, optional parameter to
    keep using the current backend until it falls sick.
  * VMOD shared libraries are now copied to the workdir, to avoid
    problems when VMODs are updated via packaging systems.
  * Bump the VRT version to 6.0.
  * Export more symbols from
  * The size of the VSL log is limited to 4G-1b, placing upper
    bounds on the -l option and the vsl_space and vsm_space
  * Added parameters clock_step, thread_pool_reserve and
  * Parameters vcl_dir and vmod_dir are deprecated, use vcl_path
    and vmod_path instead.
  * All parameters are defined, even on platforms that don't
    support them. An unsupported parameter is documented as such in Setting such a parameter is not an error, but has
    no effect.
  * Clarified the interpretations of the + and - operators in VCL
    with operands of the various data types.
  * DURATION types may be used in boolean contexts.
  * INT, DURATION and REAL values can now be negative.
  * Response codes 1000 or greater may now be set in VCL
    internally. resp.status is delivered modulo 1000 in client
  * IP addresses can be compared for equality in VCL.
  * Introduce the STEVEDORE data type, and the objects
    storage.SNAME in VCL. Added and;
    beresp.storage_hint is deprecated.

  * Varnish 5.0 changes some (mostly) internal APIs and adds some
  major new features over Varnish 4.1.
  * 5.0 supports jumping from the active VCL's vcl_recv{} to another
  VCL via a VCL label.
  * Very Experimental HTTP/2 support
  * We have added to the "directors" VMOD? an overhauled version of
  a director which was available as an out-of-tree VMOD under the
  name VSLP for a couple of years. It is basically a better hash
  director which uses consistent hashing to provide improved
  stability of backend node selection when the configuration and/or
  health state of backends changes.
  * Hit-For-Pass is now actually Hit-For-Miss
  * We have made the ban lurker even more efficient by example of
  some real live situations with tens of thousands of bans using
  inefficient regular expressions.
  * The waitinglist logic for ESI subrequests now uses condition
  variables to trigger immediate continuation of ESI processing
  when an object being waited for becomes available.
  * Backend PROXY protocol requests are now supported through the
  .proxy_header attribute of the backend definition.
  * VCL files are now also being searched for in
  /usr/share/varnish/vcl if not found in /etc/varnish.
  * The basic device detection vcl is now bundled with varnish.

  stale copy is available, serve the client the stale copy while
  fetching an updated copy from the backend in the background.
