2022-01-16machine: ssh: Add 'safety-checks?' field.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/52766>. Reported by Michael Rohleder <mike@rohleder.de>. * gnu/machine/ssh.scm (<machine-ssh-configuration>)[safety-checks?]: New field. (machine-check-file-system-availability): Return the empty list when 'safety-checks?' is false. (machine-check-initrd-modules): Likewise. * doc/guix.texi (Invoking guix deploy): Document it.
2022-01-09machine: ssh: Open a single SSH session per machine.Ludovic Courtès
Previously, any call to 'managed-host-remote-eval' and similar would open a new SSH session to the host. With this change, an SSH session is opened once, cached, and then reused by all subsequent calls to 'machine-ssh-session'. * gnu/machine/ssh.scm (<machine-ssh-configuration>): Add 'this-machine-ssh-configuration'. [session]: Mark as thunked and change default value to an 'open-machine-ssh-session*' call. (open-machine-ssh-session, open-machine-ssh-session*): New procedures. (machine-ssh-session): Replace inline code by call to 'open-machine-ssh-session'.

2021-06-20services: openssh: Replace 'without-password' by 'prohibit-password'.Brice Waegeneire
For some time, OpenSSH's option 'PermitRootLogin' has deprecated the ambiguous argument 'without-password' with 'prohibit-password'. * doc/guix.texi (Network Services): Replace 'without-password by 'prohibit-password. * gnu/machine/digital-ocean.scm (guix-infect): Change system configuration to use 'prohibit-password. * gnu/services/ssh.scm (openssh-configuration): Change comment to use 'prohibit-password. (openssh-config-file): Add support for 'prohibit-password to 'permit-root-login'.

2021-06-01machine: ssh: Gracefully handle failure of the effectful bits.Ludovic Courtès
Previously, '&inferior-exception' raised by 'upgrade-shepherd-services' and co. would go through as-is, leaving users with an ugly backtrace. * gnu/machine/ssh.scm (deploy-managed-host): Define 'eval/error-handling' and use it in lieu of EVAL as arguments to 'switch-to-system', 'upgrade-shepherd-services', and 'install-bootloader'.
2021-02-25machine: ssh: Use 'formatted-message'.Ludovic Courtès
* gnu/machine/ssh.scm (machine-check-initrd-modules): Use 'formatted-message' instead of 'format' + '&message'.

This is a followup to 70ffa8af1e93ab8a92c4622745e9cb4a2782f3c8, which did not really solve the problem. * gnu/machine/ssh.scm (not-config?): New procedure. (machine-boot-parameters): Use it as an argument to 'source-module-closure'.

[boot-parameters-store-directory-prefix]: New accessor. (read-boot-parameters): Read directory-prefix from store field. (operating-system-boot-parameters-file): Add directory-prefix to store field. * guix/scripts/system.scm (reinstall-bootloader): Use boot-parameters-store-directory-prefix. * test/boot-parameters.scm (%default-btrfs-subvolume, %default-store-directory-prefix): New variables.

2020-08-25Remove "guile-zlib" extension when unused.Mathieu Othacehe
This is a follow-up of 755f365b02b42a5d1e8ef3000dadef069553a478. As (zlib) is autoloaded in (gnu build linux-modules), "guile-zlib" is needed as an extension only when it is effectively used. * gnu/installer.scm (installer-program): Remove "guile-zlib" from 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/shadow.scm (account-shepherd-service): Ditto.
2020-08-25linux-libre: Support module compression.Mathieu Othacehe
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.
2020-07-27machine: ssh: Check for potential system downgrades.Ludovic Courtès

2020-06-18machine: ssh: Fix guix deploy hang when using non-DCE UUIDs.Maxim Cournoyer
Fixes <https://issues.guix.gnu.org/issue/41237>. The UUID type information was lost when passing to the lower gexp code strata, which led to not being able to recreate the UUID in the generated script. This occurred for non-DCE type UUIDs such as that of a FAT file system. A following commit will prevent the find-partition-by-uuid procedure from entering a loop when its UUID argument is invalid. Reported-by: Brice Waegeneire <brice@waegenei.re> * gnu/machine/ssh.scm (machine-check-file-system-availability): Replace the STRING->UUID procedure by the UUID macro, and provide the UUID type as its second argument.
