Fixes <https://bugs.gnu.org/31977>.
Reported by Paul Garlick <pgarlick@tourbillion-technology.com>.
* gnu/build/linux-container.scm (unprivileged-user-namespace-supported?):
Return #f when the 'userns-file' does not exist.
Since commit 8ce6f4dc28, importing this
module in a gexp would pull in (guix config) from the host, thereby
leading to non-reproducible derivations. Users in (gnu services ...) do
not expect that so simply remove the (guix utils) dependency for now.
* gnu/build/shepherd.scm (fork+exec-command/container)[strip-pid]: New
procedure.
Use it instead of 'strip-keyword-arguments'.
* gnu/build/image.scm (make-partition-image): Use 'raise' instead of
'format' when TYPE is not supported.
(convert-disk-image): Remove unneeded 'begin'.
Fixes: <https://issues.guix.gnu.org/44101>.
* gnu/build/bootloader.scm (write-file-on-device): Pass 'no-fail flag instead
of 'no-create. Use a latin-1 transcoder.
* guix/scripts/system/reconfigure.scm (install-bootloader-program): Add a
"disk-installer" argument and use it as a fallback.
(install-bootloader): Adapt accordingly.
* gnu/tests/reconfigure.scm (run-install-bootloader-test): Ditto.
This is a follow-up of f19cf27c2b. The
bootloader installation must be done on the final disk-image, hence using
"disk-image-installer" instead of "installer" callback.
* gnu/bootloader/u-boot.scm: Turn all installer callbacks into
disk-image-installer callbacks.
* gnu/build/bootloader.scm (write-file-on-device): Open the output file with
'no-truncate and 'no-create options.
* gnu/system/image.scm (with-imported-modules*): Add (gnu build bootloader)
module.
This allows the client running on the host to know when it's actually
connect to the server running in the guest. Failing that, the client
would connect right away to QEMU and send secrets even though the server
is not running yet in the guest, which is unreliable.
* gnu/build/secret-service.scm (secret-service-send-secrets): Add
#:handshake-timeout. Read from SOCK an initial message from the
server. Return #f on error.
(secret-service-receive-secrets): Send 'secret-service-server' message
to the client. Close SOCK upon timeout.
* gnu/services/virtualization.scm (hurd-vm-shepherd-service): 'start'
method returns #f when 'secret-service-send-secrets' returns #f.
* gnu/build/secret-service.scm (secret-service-receive-secrets)
[wait-for-client]: Call 'select' with a 60s timeout before 'accept'.
Return #f upon timeout.
[read-secrets]: Return FILES on success.
Adjust caller of 'wait-for-client' to handle #f.
* gnu/build/image.scm (convert-disk-image): New procedure.
(genimage): Remove target argument.
* gnu/system/image.scm (system-disk-image): Add support for 'compressed-qcow2
image format. Call "convert-disk-image" to apply image conversions on the
final image. Add "qemu-minimal" to the build inputs.
(system-image): Also add support for 'compressed-qcow2.
Fixes: <https://issues.guix.gnu.org/43533>.
* gnu/build/shepherd.scm (fork+exec-command/container): Check if containers
are supported before joining PID namespaces.
This is a follow-up of 5316dfc0f1. Some users of
run-container may expect that the container is jailed, even if there are no
mounts. This is the case for some Guix tests.
* gnu/build/linux-container.scm (run-container): Do not jail the container
when the requested root is "/".
When the store overlay is mounted, other processes such as kmscon, udev
and guix-daemon may open files from the store, preventing the
underlying install support from being umounted. See:
https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00161.html.
To avoid this situation, mount the store overlay inside a container,
and run the installation from within that container.
* gnu/build/shepherd.scm (fork+exec-command/container): New procedure.
* gnu/services/base.scm (guix-shepherd-service): Support an optional PID
argument passed to the "start" method. If that argument is passed, ensure that
guix-daemon enters the given PID MNT namespace by using
fork+exec-command/container procedure.
* gnu/installer/final.scm (umount-cow-store): Remove it,
(install-system): run the installation from within a container.
* gnu/installer/newt/final.scm (run-install-shell): Remove the display hack.
We may want to run a container inside the MNT namespace, without jailing the
container. If RUN-CONTAINER is passed a null MOUNTS list, do not jail the
container.
* gnu/build/linux-container.scm (run-container): Do not call
MOUNT-FILE-SYSTEMS if MOUNTS list is empty.
Move the cow-store procedure from the service declaration in (gnu system
install) to (gnu build install), so that it can be called from within a
different context than Shepherd.
* gnu/build/install.scm (mount-cow-store, unmount-cow-store): New procedures.
* gnu/system/install.scm (make-cow-store): Remove it,
(cow-store-service-type): adapt it accordingly.
This adds a "secret-service" that can be added to a Childhurd VM to receive
out-of-band secrets (keys) sent from the host.

* gnu/services/virtualization.scm (secret-service-activation): New procedure.
(secret-service-type): New variable.
* gnu/build/secret-service.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
This commit adds support for GZIP compression for linux-libre kernel
modules. The initrd modules are kept uncompressed as the initrd is already
compressed as a whole.
The linux-libre kernel also supports XZ compression, but as Guix does not have
any available bindings for now, and the compression time is far more
significant, GZIP seems to be a better option.
* gnu/build/linux-modules.scm (modinfo-section-contents): Use
'call-with-gzip-input-port' to read from a module file using '.gz' extension,
(strip-extension): new procedure,
(dot-ko): adapt to support compression,
(ensure-dot-ko): ditto,
(file-name->module-name): ditto,
(find-module-file): ditto,
(load-linux-module*): ditto,
(module-name->file-name/guess): ditto,
(module-name-lookup): ditto,
(write-module-name-database): ditto,
(write-module-alias-database): ditto,
(write-module-device-database): ditto.
* gnu/installer.scm (installer-program): Add "guile-zlib" to the extensions.
* gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto.
* gnu/services.scm (activation-script): Ditto.
* gnu/services/base.scm (default-serial-port): Ditto,
(agetty-shepherd-service): ditto,
(udev-service-type): ditto.
* gnu/system/image.scm (gcrypt-sqlite3&co): Ditto.
* gnu/system/linux-initrd.scm (flat-linux-module-directory): Add "guile-zlib"
to the extensions and make sure that the initrd only contains
uncompressed module files.
* gnu/system/shadow.scm (account-shepherd-service): Add "guile-zlib" to the
extensions.
* guix/profiles.scm (linux-module-database): Ditto.
* gnu/system/file-systems.scm (<file-system>): Add a mount-may-fail? field.
(file-system->spec): adapt accordingly,
(spec->file-system): ditto.
* gnu/build/file-systems.scm (mount-file-system): If 'system-error is raised
and mount-may-fail? is true, ignore it. Otherwise, re-raise the exception.

This fixes <https://bugs.gnu.org/42151>.
* gnu/system/images/hurd.scm (hurd-initialize-root-partition): Use #:wal-mode #f
in call to ...
* gnu/build/image.scm (initialize-root-partition): ... this, add #:wal-mode?
parameter, pass it to ...
(register-closure): ... this, add #:wal-mode? parameter, pass it to ...
* guix/store/database.scm (with-database): ... this, add #:wal-mode?
parameter, pass it to ...
(call-with-database): ... this, add #:wal-mode? parameter; when
set to #f, do not set journal_model=WAL.
The "image-root" derivation output is used as a temporary directory that is
passed to mke2fs and mkdosfs later on. By merging the creation of this
directory and the production of partition images, we can get rid of the
derivation.
As mke2fs and mkdosfs are not able to override file permissions, call those
commands with fakeroot. This way, all the image files will be owned by root,
even if image generation is done in an unprivilegded context.
* gnu/system/image.scm (system-disk-image): Merge "image-root" and
"iso9660-image" derivations so that we spare an extra derivation. Also add
"fakeroot" and its runtime dependencies to the inputs.
* gnu/build/image.scm (make-ext-image, make-vfat-image): Make sure that mke2fs
and mkdosfs are respectively called by fakeroot.
Note: Using `getxattr' on the Hurd instead of running showtrans does not
work (yet?).
* gnu/build/hurd-boot.scm (setup-translator): Use 'setxattr' instead of
invoking settrans.
* gnu/system.scm (hurd-multiboot-modules): Add --x-xattr-translator-records to
enable xattr-embedding of translators.
* gnu/build/hurd-boot.scm (make-hurd-device-nodes): Do not create
dev/{null,zero,full,random,urandom} mount points.
(passive-translator-xattr?, passive-translator-installed?, translated?,
set-translator, set-hurd-device-translators): New procedures.
(false-if-EEXIST): New macro.
(boot-hurd-system): Use them instead of running MAKEDEV.
This mirrors a change made in the Shepherd 0.8.0. Previously, upon
startup failure, we could have left processes behind.
* gnu/build/shepherd.scm (read-pid-file/container): Kill (- PID) instead
of PID.
Fixes <https://bugs.gnu.org/41791>.
Reported by Tobias Geerinckx-Rice <me@tobias.gr>.
This change mirrors changes made in the Shepherd 0.8.1, where signals
are blocked in the shepherd process in support of 'signalfd'. The
regression was introduced with the switch to 0.8.1 in
3f9c62d1a8: child processes would not
receive SIGTERM upon 'herd stop SERVICE'.
* gnu/build/shepherd.scm <top level>: Autoload (shepherd system).
(make-forkexec-constructor/container): Call call to 'sigaction' and
'unblock-signals'.
* gnu/build/activation.scm (boot-time-system):
Evaluate the linux-command-line thunk for linux systems to boot
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
Calling "mknod" without root permissions fails. Plus those device nodes do not
appear to be needed to boot.
* gnu/build/image.scm (initialize-root-partition): Do not use
make-essential-device-nodes as default make-device-nodes procedure.
This decouples startup of the Hurd from the "hurd" package, moving the RC
script into SYSTEM.
* gnu/packages/hurd.scm (hurd)[inputs]: Remove hurd-rc-script.
[arguments]: Do not substitute it. Update "runsystem.sh" to parse kernel
arguments and exec into --system=SYSTEM/rc.
(hurd-rc-script): Move to...
* gnu/services.scm (%hurd-rc-file): ...this new variable.
(hurd-rc-entry): New procedure.
(%hurd-startup-service): Use it in new variable.
* gnu/system.scm (hurd-default-essential-services): Use it.
* gnu/build/activation.scm (boot-time-system): Use "command-line" for the
Hurd.
* gnu/system.scm (hurd-default-essential-services): Add %boot-service and
%activation-service.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Remove #:target.
[builder]: Use #+. Don't pass #:target-arm32? and #:target-aarch64? to
'load-in-linux-vm'.
Pass #:target #f to 'gexp->derivation'.
(qemu-image): Adjust accordingly.
* gnu/build/vm.scm (load-in-linux-vm): Remove #:target-aarch64?
and #:target-arm32?. Define them as local variables.
* gnu/build/image.scm (initialize-root-partition): Add bootloader-package and
bootloader-installer arguments. Run the bootloader-installer if defined.
* gnu/system/image.scm (system-disk-image): Adapt the partition initializer
call accordingly.
