Varnish 7.4.2
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture.

7.4.229 Jan 2024 13:44
major bugfix:
* The ``vcl_req_reset`` feature (controllable through the ``feature``
parameter, see `varnishd(1)`) has been added and enabled by default
to terminate client side VCL processing early when the client is
gone.
*req_reset* events trigger a VCL failure and are reported to
`vsl(7)` as ``Timestamp: Reset`` and accounted to ``main.req_reset``
in `vsc` as visible through ``varnishstat(1)``.
In particular, this feature is used to reduce resource consumption
of HTTP/2 "rapid reset" attacks (see below).
Note that *req_reset* events may lead to client tasks for which no
VCL is called ever. Presumably, this is thus the first time that
valid `vcl(7)` client transactions may not contain any ``VCL_call``
records.
* Added mitigation options and visibility for HTTP/2 "rapid reset"
attacks (CVE-2023-44487_, 3996_, 3997_, 3998_, 3999_).
Global rate limit controls have been added as parameters, which can
be overridden per HTTP/2 session from VCL using the new vmod ``h2``:
* The ``h2_rapid_reset`` parameter and ``h2.rapid_reset()`` function
define a threshold duration for an ``RST_STREAM`` to be classified
as "rapid": If an ``RST_STREAM`` frame is parsed sooner than this
duration after a ``HEADERS`` frame, it is accounted against the
rate limit described below.
The default is one second.
* The ``h2_rapid_reset_limit`` parameter and
``h2.rapid_reset_limit()`` function define how many "rapid" resets
may be received during the time span defined by the
``h2_rapid_reset_period`` parameter / ``h2.rapid_reset_period()``
function before the HTTP/2 connection is forcibly closed with a
``GOAWAY`` and all ongoing VCL client tasks of the connection are
aborted.
The defaults are 100 and 60 seconds, corresponding to an allowance
of 100 "rapid" resets per minute.
* The ``h2.rapid_reset_budget()`` function can be used to query the
number of currently allowed "rapid" resets.
* Sessions closed due to
7.4.029 Jan 2024 13:11
major bugfix:
* The ``VSB_quote_pfx()`` (and, consequently, ``VSB_quote()``) function
no longer produces `` v`` for a vertical tab. This improves
compatibility with JSON.
* The bundled *zlib* has been updated to match *zlib 1.3*.
* The ``VSHA256_*`` functions have been added to libvarnishapi (3946_).
* Tabulation of the ``vcl.list`` CLI output has been modified
slightly.
* VCL now supports "protected headers", which can neither be set nor unset.
* The ``Content-Length`` and ``Transfer-Encoding`` headers are now
protected. For the common use case of ``unset
xxx.http.Content-Length`` to dismiss a body, ``unset xxx.body``
should be used.
* Error handling of numeric literals in exponent notation has been
improved in the VCL compiler (3971_).
* Finalization of the storage private state of busy objects has been
fixed. This bug could trigger a panic when ``vcl_synth `` was used
to replace the object body and storage was changed from one of the
built-in storage engines to a storage engine from an extension (3953_).
* HTTP/2 header field validation is now more strict with respect to
allowed characters (3952_).
* A bug has been fixed in the filter handling code which could trigger
a panic when ``resp.filters`` was used from ``vcl_synth `` (3968_).
* The utility macros ``ALLOC_OBJ_EXTRA()`` and ``ALLOC_FLEX_OBJ()``
have been added to ``miniobj.h`` to simplify allocation of objects
larger than a struct and such with a flexible array.
* The ``varnishapi`` version has been increased to 3.1 and the
functions ``VENC_Encode_Base64()`` and ``VENC_Decode_Base64()`` are
now exposed.
* Two bugs in the ban expression parser have been fixed where one of them
could lead to a panic if a ban expression with an empty header name was
issued (3962_).
* The ``v_cold`` macro has been added to add ``__attribute__((cold))``
on compilers supporting it. It is used for ``VRT_fail()`` to mark
failure code paths as cold.
* ``varnishtest`` now generates ``User-
