+
+@item #:out-of-source?
+This Boolean, @code{#f} by default, indicates whether to run builds in a
+build directory separate from the source tree.
+
+When it is true, the @code{configure} phase creates a separate build
+directory, changes to that directory, and runs the @code{configure}
+script from there.  This is useful for packages that require it, such as
+@code{glibc}.
+
+@item #:tests?
+This Boolean, @code{#t} by default, indicates whether the @code{check}
+phase should run the package's test suite.
+
+@item #:test-target
+This string, @code{"check"} by default, gives the name of the makefile
+target used by the @code{check} phase.
+
+@item #:parallel-build?
+@itemx #:parallel-tests?
+These Boolean values specify whether to build, respectively run the test
+suite, in parallel, with the @code{-j} flag of @command{make}.  When
+they are true, @code{make} is passed @code{-j@var{n}}, where @var{n} is
+the number specified as the @option{--cores} option of
+@command{guix-daemon} or that of the @command{guix} client command
+(@pxref{Common Build Options, @option{--cores}}).

+the @code{RUNPATH} of ELF binaries (@code{.so} shared libraries as well
+as executables) previously installed by the @code{install} phase.
+
+This validation step consists in making sure that all the shared
+libraries needed by an ELF binaries, which are listed as
+@code{DT_NEEDED} entries in its @code{PT_DYNAMIC} segment, appear in the
+@code{DT_RUNPATH} entry of that binary.  In other words, it ensures that

+error at run time.  @xref{Options, @option{-rpath},, ld, The GNU

+substitutes for them instead of building locally (@pxref{Substitutes}).

+escalation has been found in the code that creates user accounts on Guix
+System---Guix on other distros is unaffected.  The system is only vulnerable
+during the activation of user accounts that do not already exist.
+
+This bug is fixed and Guix System users are advised to upgrade their system,
+with a command along the lines of:
+
+@example
+guix system reconfigure /run/current-system/configuration.scm
+@end example
+
+The attack can happen when @command{guix system reconfigure} is running.
+Running @command{guix system reconfigure} can trigger the creation of new user
+accounts if the configuration specifies new accounts.  If a user whose account
+is being created manages to log in after the account has been created but
+before ``skeleton files'' copied to its home directory have the right
+ownership, they may, by creating an appropriately-named symbolic link in the
+home directory pointing to a sensitive file, such as @file{/etc/shadow}, get
+root privileges.
+
+See @uref{https://issues.guix.gnu.org/47584} for more information on this
+bug.")

+
+Der Fehler wurde behoben und wir empfehlen Nutzern von Guix System, ihre
+Systeme zu aktualisieren, mit einem Befehl wie:
+
+@example
+guix system reconfigure /run/current-system/configuration.scm
+@end example
+
+Der Angriff kann erfolgen, während @command{guix system reconfigure} läuft.
+Wenn @command{guix system reconfigure} ausgeführt wird, kann das die Erzeugung
+neuer Benutzerkonten auslösen, wenn in der Konfiguration neue Konten angegeben
+wurden.  Wenn ein Benutzer, dessen Konto gerade angelegt wird, es
+fertigbringt, sich anzumelden, bevor „Skeleton-Dateien“ in seinem Persönlichen
+Verzeichnis den richtigen Besitzer haben, kann er durch Anlegen einer gezielt
+benannten symbolischen Verknüpfung in seinem Persönlichen Verzeichnis auf eine

+after they have been inadvertently deleted or the primary partition table at
+sector 0 damaged.  In both cases, the contents of these partitions still exist
+on the disk but the operating system cannot access them.
+
+Gpart ignores the partition table and scans each sector of the device or image
+file for several known file system and partition types.  Only partitions which
+have been formatted in some way can be recognized.  Several file system guessing
+modules are built in; more can be written and loaded at run time.
+
+The guessed table can be restored manually, for example with @command{fdisk},
+written to a file, or---if you firmly believe it's entirely correct---directly
+to disk.
+
+It should be stressed that gpart does a very heuristic job.  It can easily be
+right in its guesswork but it can also be terribly wrong.  Never believe its
+output without any plausibility checks.")

+Subject: [PATCH] build: fix netinet/sctp.h not to be installed
+
+After libcnetinet_HEADERS was set to sctp.h.in, netinet/sctp.h can
+no longer be installed into ${includedir}.
+
+Since "AC_CONFIG_HEADERS([src/include/netinet/sctp.h])" is already
+added into configure.ac, there's no need to generate sctp.h by
+automake.
+
+So we simply set libcnetinet_HEADERS back to sctp.h.

+    http: unset `F_CHUNKED` on new `Transfer-Encoding`
+    
+    Duplicate `Transfer-Encoding` header should be a treated as a single,
+    but with original header values concatenated with a comma separator. In
+    the light of this, even if the past `Transfer-Encoding` ended with
+    `chunked`, we should be not let the `F_CHUNKED` to leak into the next
+    header, because mere presence of another header indicates that `chunked`
+    is not the last transfer-encoding token.

+Subject: [PATCH] patch rktio_process for "/bin/sh" on Guix
+
+Racket provides the functions `system` and `process`,
+which execute shell commands using `sh` (or `cmd` on Windows).
+Racket assumes that `sh` can be found at "/bin/sh",
+which is not necessarily true on Guix.
+
+This patch adds a special case for "/bin/sh" to `rktio_process`,
+the C function that implements the core of `system`, `process`,
+and related Racket functions.
+
+Guix should enable the special case by defining the C preprocessor
+macro `GUIX_RKTIO_PATCH_BIN_SH` with the path to `sh` in the store.
+If:
+
+    1. The `GUIX_RKTIO_PATCH_BIN_SH` macro is defined; and
+
+    2. `rktio_process` is called with the exact path "/bin/sh"; and
+
+    3. The path specified by `GUIX_RKTIO_PATCH_BIN_SH` does exists;
+
+then `rktio_process` will execute the file specified
+by `GUIX_RKTIO_PATCH_BIN_SH` instead of "/bin/sh".
+
+Compared to previous attempts to patch the Racket sources,
+making this change at the C level is both:
+
+    - More comprehensive: it catches all attempts to execute "/bin/sh",
+      without having to track down the source of every occurance; and
+

-Subject: [PATCH] nsenter: clone /proc/self/exe to avoid exposing host binary
- to container
-
-There are quite a few circumstances where /proc/self/exe pointing to a
-pretty important container binary is a _bad_ thing, so to avoid this we
-have to make a copy (preferably doing self-clean-up and not being
-writeable).
-
-We require memfd_create(2) -- though there is an O_TMPFILE fallback --
-but we can always extend this to use a scratch MNT_DETACH overlayfs or
-tmpfs. The main downside to this approach is no page-cache sharing for
-the runc binary (which overlayfs would give us) but this is far less
-complicated.
-
-This is only done during nsenter so that it happens transparently to the
-Go code, and any libcontainer users benefit from it. This also makes
-ExtraFiles and --preserve-fds handling trivial (because we don't need to
-worry about it).
-
-Fixes: CVE-2019-5736

+From a0541334a6394f8237a4393b7372693cd7e96f15 Mon Sep 17 00:00:00 2001
+From: Jouni Malinen <j@w1.fi>
+Date: Sat, 13 Mar 2021 18:19:31 +0200
+Subject: ASN.1: Validate DigestAlgorithmIdentifier parameters
+
+The supported hash algorithms do not use AlgorithmIdentifier parameters.
+However, there are implementations that include NULL parameters in
+addition to ones that omit the parameters. Previous implementation did
+not check the parameters value at all which supported both these cases,
+but did not reject any other unexpected information.
+
+Use strict validation of digest algorithm parameters and reject any
+unexpected value when validating a signature. This is needed to prevent
+potential forging attacks.
