* libsystemd: turn json.[ch] into a public APILennart Poettering2024-06-121-0/+2
| | | | | | | | | | | | | | | This is preparation for making our Varlink API a public API. Since our Varlink API is built on top of our JSON API we need to make that public first (it's a nice API, but JSON APIs there are already enough, this is purely about the Varlink angle). I made most of the json.h APIs public, and just placed them in sd-json.h. Sometimes I wasn't so sure however, since the underlying data structures would have to be made public too. If in doubt I didn#t risk it, and moved the relevant API to src/libsystemd/sd-json/json-util.h instead (without any sd_* symbol prefixes). This is mostly a giant search/replace patch.
* repart: Use crypt_reencrypt_run() if availableDaan De Meyer2024-06-121-0/+1
| | | | | crypt_reencrypt() is deprecated, so let's look for and prefer crypt_reencrypt_run() if it is available.
* meson: Pass -Wno-deprecated-declarations when detecting libcryptsetup functionsDaan De Meyer2024-06-031-0/+3
| | | | Otherwise we fail to detect crypt_reencrypt() if -Werror is used.
* meson: add static libs to libudev/libsystemd target aliasesLuca Boccassi2024-06-011-4/+12
| | | | | If static libraries are enabled, then group them in the build target together with the shared libraries, to match the install tags.
* meson: add alias targets to group nss and pam modulesLuca Boccassi2024-05-311-0/+15
| | | | | | Add aliases grouping these modules, so that they can be built without knowing the SONAME version in advance. Match the install tag names.

* libsystemd: link with '-z nodelete'Michal Sekletar2024-05-221-0/+2
| | | | | | | We want to avoid reinitialization of our global variables with static storage duration in case we get dlopened multiple times by the same application. This will avoid potential resource leaks that could have happened otherwise (e.g. leaking journal socket fd).
* pidfd: properly detect if libc offers pidfd syscalls and make use of them thenLennart Poettering2024-05-081-2/+4
| | | | | We never updated the meson checks when glibc finally learned about these syscalls, address that.
* tree-wide: add dlopen ELF notes to all dlopen() deps of oursLennart Poettering2024-05-081-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use 'recommended' priority for the default compression library, to indicate that it should be prioritized over the other ones, as it will be used to compress journals/core files. Also use 'recommended' for kmod, as systems will likely fail to boot if it's missing from the initrd. Use 'suggested' for everything else. There is one dlopen'ed TPM library that has the name generated at runtime (depending on the driver), so that cannot be added, as it needs to be known at build time. Also when we support multiple ABI versions list them all, as for the same reason we cannot know which one will be used at build time. $ dlopen-notes.py build/libsystemd.so.0.39.0 build/src/shared/libsystemd-shared-256.so libarchive.so.13 suggested libbpf.so.0 suggested libbpf.so.1 suggested libcryptsetup.so.12 suggested libdw.so.1 suggested libelf.so.1 suggested libfido2.so.1 suggested libgcrypt.so.20 suggested libidn2.so.0 suggested libip4tc.so.2 suggested libkmod.so.2 recommended liblz4.so.1 suggested liblzma.so.5 suggested libp11-kit.so.0 suggested libpcre2-8.so.0 suggested libpwquality.so.1 suggested libqrencode.so.3 suggested libqrencode.so.4 suggested libtss2-esys.so.0 suggested libtss2-mu.so.0 suggested libtss2-rc.so.0 suggested libzstd.so.1 recommended Co-authored-by: Luca Boccassi <bluca@debian.org>
* test: Only set environment variable if integration tests are enabled.Daan De Meyer2024-05-061-8/+8
| | | | | | | | | If we set it to '0' if integration tests are not enabled then we can't enable them from the command line since environment from meson takes priority over environment variables from the command line. We also rename the related variables to avoid conflicts with the existing integration_tests variable.
* meson: Remove --debug from mkosi argumentsDaan De Meyer2024-05-051-1/+0
| | | | | The exit status issue for which we introduced this was fixed so let's remove --debug again to make the meson output less verbose.
* meson: bump libbpf dependency to 1.4.0 when using gccLuca Boccassi2024-04-301-1/+1
| | | | | | | | | | | | | bpf_core_type_id_kernel() needs libbpf 1.4.0 when building with gcc rather than clang, so bump the dependency accordingly. More precisely, the following change is needed: https://github.com/libbpf/libbpf/commit/b19fdbf1be21a28f88740375a575ebd9dfbea68f Related to: https://github.com/systemd/systemd/issues/31869 Follow-up for 8aee931e7ae1adb01eeac0e1e4c0aef6ed3969ec

* meson: Properly check dependencies of mkosi targetDaan De Meyer2024-04-251-6/+15
| | | | | | | Let's insist on mkosi being found if the integration-tests option is enabled and let's only add dependencies on systemd-journal-remote and systemd-measure if they're being built. Drop ukify from the list as its part of public_programs.

* test: Various mkosi integration test improvementsDaan De Meyer2024-04-231-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Stop using logging module since the default output formatting is pretty bad. Prefer print() for now. - Log less, logging the full mkosi command line is rather verbose, especially when it contains multi-line dropins. - Streamline the journalctl command we output for debugging failed tests. - Don't force usage of the disk image format. - Don't force running without unit tests. - Don't force disabling RuntimeBuildSources. - Update documentation to streamline the command for running a single test and remove sudo as it's not required anymore. - Improve the console output by having the test unit's output logged to both the journal and the console. - Disable journal console log forwarding as we have journal forwarding as a better alternative. - Delete existing journal file before running test. - Delete journal files of succeeded tests to reduce disk usage. - Rename system_mkosi target to just mkosi - Pass in mkosi source directory explicitly to accomodate arbitrary build directory locations. - Add test interactive debugging if stdout is connected to a tty - Stop explicitly using the 'system' image since it'll likely be dropped soon. - Only forward journal if we're not running in debugging mode. - Stop using testsuite.target and instead just add the necessary extras to the main testsuite unit via the credential dropin. - Override type to idle so test output is not interleaved with status output. - Don't build mkosi target by default - Always add the mkosi target if mkosi is found - Remove dependency of the integration tests on the mkosi target as otherwise the image is always built, even though we configure it to not be built by default. - Move mkosi output, cache and build directory into build/ so that invocations from meson and regular invocations share the same directories. - Various aesthetic cleanups.

* nsresourced: add new daemon for granting clients user namespaces and ↵Lennart Poettering2024-04-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | assigning resources to them This adds a small, socket-activated Varlink daemon that can delegate UID ranges for user namespaces to clients asking for it. The primary call is AllocateUserRange() where the user passes in an uninitialized userns fd, which is then set up. There are other calls that allow assigning a mount fd to a userns allocated that way, to set up permissions for a cgroup subtree, and to allocate a veth for such a user namespace. Since the UID assignments are supposed to be transitive, i.e. not permanent, care is taken to ensure that users cannot create inodes owned by these UIDs, so that persistancy cannot be acquired. This is implemented via a BPF-LSM module that ensures that any member of a userns allocated that way cannot create files unless the mount it operates on is owned by the userns itself, or is explicitly allowelisted. BPF LSM program with contributions from Alexei Starovoitov.

By turning this into a dlopen() dependency, we can make our depchain during install time quite a bit smaller. In particular as inside of containers kmod doesn't help anyway as CAP_SYS_MODULE is not available anyway. While we are at it, also share the code that sets up logging/kmod context.

* ssh-generator: create privsep dir via tmpfiles.d/ if we are told toLennart Poettering2024-04-031-0/+5
| | | | | | | | | | | | | | | | | | To make it easy to have a workable ssh-generator on various distros, let's optionally generate the ssh privsep dir via tmpfiles.d/ drop-in. This enables the concept with a path of /run/sshd/ as default. This is the path Debian/Ubuntu uses, and means that we just work on those distros. Debian/Ubuntu is the only distro (apparently?) that puts the privsep dir under /run/, hence always needs the dir to be created manually. Other distros don't need it that much, because they place the dir in /usr/ (fedora, best choice!) or /var/ (others, not ideal, because still mutable). Also adds a longer explanation about this in NEWS, in the hope that distro maintaines read that and maybe start cleaning this up. Alternative to: #31543
* gcrypt: dlopenify for libsystemdLuca Boccassi2024-04-031-4/+5
| | | | | | | | | gcrypt is used only for journal sealing operations in libsystemd, so it can be made into a dlopen dependency that is used only on demand. This allows to reduce the footprint of libsystemd in the most common cases. Keep systemd-pull and systemd-resolved with normal linking, as they are executables, and usually built with OpenSSL support anyway.

| * homework: Always upload volume key to keyringAdrian Vovk2024-03-231-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit makes homework always upload the LUKS volume key into the kernel keyring. This is different from previous behavior in three notable ways: - Previously, we'd only upload if auto-resize was on. In preparation for upcoming changes, now we always upload - Previously, we'd upload the user's actual password (or a password obtained from a FIDO key or similar). Now, we upload the LUKS volume key itself, to remove a layer of unnecessary indirection. - Previously, Lock() wouldn't remove the key from the kernel keyring. This, of course, defeats the purpose of Lock(), so now it removes the key This commit also allows the LUKS volume to be unlocked using the volume key we obtained from the keyring.

* meson: always use vcs_tagZbigniew Jędrzejewski-Szmek2024-03-131-14/+9
| | | | | | | | | | | | | | | | | The branch with configure_file() was broken: meson doesn't know that this file is a prerequisite for other targets, so partial rebuilds were broken. Easy reproducer: git mv .git{,.no} touch meson build && ninja -C build src/basic/libbasic.a rm build/version.h ninja -C build src/basic/libbasic.a Using vcs_tag() also in that case makes meson always build the file. (Combined with the issue fixed in previous commit, I was encountering failed builds quite often.) Fixes 3f6ce3d4f04de0f765bb3bde0e400d0823829486.
* meson: .git can also be a fileZbigniew Jędrzejewski-Szmek2024-03-131-1/+1
| | | | | | | With git-worktree, .git is just a file that specifies where the parent git directory is. All the git information is available in a git worktree, so it should be treated the same as a checkout with a .git directory.
* meson: Remove version_h dependency from jinja2_cmdlineDaan De Meyer2024-03-061-1/+1
| | | | | | | | version_h includes GIT_VERSION which only makes sense for C files which aren't preprocessed by jinja2 so remove the argument. The end result of this change is that the man pages are not recompiled anymore every time GIT_VERSION changes.
* dynamically load compression librariesMatteo Croce2024-03-051-6/+7

* rpm/macros: add %_kernel_install_dirZbigniew Jędrzejewski-Szmek2024-02-291-0/+1
| | | | | | | | | | This makes it easier for people packaging kernel-install plugins to get the path right. E.g. https://src.fedoraproject.org/rpms/python-virt-firmware/pull-request/3 fixes an issue where %{_libdir}/kernel/install.d was used, which gives incorrect results on 64-bit architectures. %_kernel_install_dir will make this even easier.
* tree-wide: use "_" rather than "-" as separator in kernel cmdline optionsLennart Poettering2024-02-281-2/+2
| | | | | | | | | | | Most of our kernel cmdline options use underscores as word separators in kernel cmdline options, but there were some exceptions. Let's fix those, and also use underscores. Since our /proc/cmdline parsers don't distinguish between the two characters anyway this should not break anything, but makes sure our own codebase (and in particular docs and log messages) are internally consistent.
