* tree-wide: add dlopen ELF notes to all dlopen() deps of oursLennart Poettering2024-05-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* various: use strdup_to() in various obvious casesZbigniew Jędrzejewski-Szmek2024-03-201-5/+1
| | | | | strdup_to() returns 0 on success and here we convert obvious blocks which either return -ENOMEM or 0.
* kbd-util: allow to override the default keymap directoriesYu Watanabe2024-03-141-4/+10
| | | | | | | | | | | | | | This introduces $SYSTEMD_KEYMAP_DIRECTORIES environment variable to override the hardcoded keymap directories. I think it is not necessary to provide the first class configuration option for controlling the keymap directories, but it is not good to hardcode the paths. So, let's introduce an environment variable to override that. Prompted by #31759. Closes #31759.
* locale: use O_PATH directory fd and faccessat() in find_converted_keymap()Yu Watanabe2024-03-141-9/+16
| | | | | | | | | Previously, it is assumed that the paths in KBD_KEYMAP_DIRS are ended with a slash. But, in the next commit, paths will become controllable by users, and each path may not be ended with a slash. This should not change any effective behaviors. Just refactoring and preparation.
* polkit: turn "interactive" flag to polkit APIs into a proper flags field ↵Lennart Poettering2024-03-111-3/+3
| | | | | | | | | | | | (#31715) This adds for both the D-Bus and the Varlink flavours of our polkit client api a flags parameter. And then folds the "bool interactive" flag that the D-Bus version so far had, into a flag, and also adds support for it in the Varlink API. Since this means the Varlink API gained another parameter, let's do what we already did for the D-Bus API and add a _full() version of the API that has the flags and the good_uid parameter, and one without both.
* tree-wide: switch dlopen hooks over to DLSYM_PROTOTYPE()/DLSYM_FUNCTION()Lennart Poettering2024-03-012-28/+12
| | | | | | | | | | | | | | | | | | | | | | | | | We have these pretty macros, let's use them everywhere (so far we mostly used them for newer additions only). This PR is mostly an excercise in "perl -p -i -e", but there are some special cases: * idn-util.c exposes a function whose prototype in the official library headers is marked with the "const" attribute, and this apparently does not propagate along typeof() correctly and then __builtin_types_compatible_p() fails later because it detects that prototype and original function don't match in prototype. * libbpf removed some symbols in newer versions, hence we need to define some prototypes manually to still be able to build. * libcryptsetup marked a symbol as deprecated we want to use (knowing it is deprecated). By using the macros this is detected by the compiler. We work around it via the usual warning off macros. Note by using these macros we assume that all symbols are known during build time. Which might not be the case. We might need to revert this commit for some symbols if this trips up builds on older distros.

* polkit: simplify bus_verify_polkit_async() + drop auth-by-cap dbus featureLennart Poettering2023-12-211-12/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies bus_verify_polkit_async() and related calls quite a bit: 1. This removes any support for authentication-by-Linux-capability. This is ultimately a kdbus leftover: with classic AF_UNIX transports we cannot authenticate by capabilities securely (because we cannot acquire it from the peer without races), hence we never actually did. Since the necessary kernel work didn't materialize in the last 10y, and is unlikely to be added, let's just kill this context. We cannot quite remove the caps stuff from sd-bus for API compat, but for our polkit logic let's kill it. 2. The "good_uid" and "interactive" params are only necessary in very few cases, hence let's move them to a new call bus_verify_polkit_async_full() and make bus_verify_polkit_async() a wrapper around it without those two parameters. This also fixes a bunch of wrong uses of the "interactive" bool. The bool makes no sense today as the ALLOW_INTERACTIVE_AUTHORIZATION field in the D-Bus message header replaces it fully. We only need it to implement method calls we introduced prior to that header field becoming available in D-Bus. And it should only be used on such old method calls, and otherwise always be set to false. This does not change behaviour in any way. Just simplifies stuff. Fixes: #21586
* tree-wide: use the usual spelling of "cannot"Zbigniew Jędrzejewski-Szmek2023-11-131-1/+1

* find_legacy_keymap: extend variant match bonus againAdam Williamson2023-09-222-1/+8
| | | | | | | | | | | | If the column is "-" and the X context variant specifer only contains commas, we should also give the match bonus. The variant string is supposed to be a comma-separated list as long as the list of layouts, so it's quite natural for consumers to be written in such a way that they pass a string only containing commas if there are multiple layouts and no variants. anaconda is a real world case that does this.

* find_legacy_keymap: try matching with layout order reversedAdam Williamson2023-09-192-16/+33
| | | | | | | | | | | | | | | | | | | | | | | The lines in kbd-model-map date back to ye olde times (RH's old system-config-keyboard), and I think predate this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1039185 where we got strong feedback that, for 'switched' layout setups like Russian, US English should be the *first* layout and the native layout the *second* one. This is how anaconda and, as of recently, gnome-initial-setup configure such cases - but that means, if we try to use localed to convert these configurations using kbd-model-map, we get the wrong result (we get "us" as the console layout). See also: https://bugzilla.redhat.com/show_bug.cgi?id=1912609 where we first noticed this wasn't working right, but sadly, we 'fixed' it with a not-really-correct bodge in anaconda instead of doing it properly.

* find_legacy_keymap: fix empty variant matchingAdam Williamson2023-09-192-1/+13
| | | | | | | | | | | | We should give a match bonus if the X context variant is empty and the xvariant column in kbd-model-map is "-" (which means none). Currently, we don't, which means that if you call this on a context with layouts bg,us and no variant, you get the console layout bg_pho-utf8 instead of bg_bds-utf8 (because both score the same, and the bg_pho-utf8 row comes first). You should get bg_bds-utf8 in this case. Signed-off-by: Adam Williamson <awilliam@redhat.com>

* bus-unit-util: add common code for reloading PID 1Lennart Poettering2023-07-101-13/+2
| | | | | | We have this very similar code in various places, and it#s not entirely obvious (since we want a prolonged timeout for the reload), hence unify this at one place.
* kbd-model-map: change the order of Hungarian keymapsBalló György2023-06-071-2/+2
| | | This changes the console layout from 'hu101' to 'hu' when the user calls 'localectl set-x11-keymap hu', because 'hu' is the expected layout instead of 'hu101' for most users.
* label: Introduce LabelOps to do pre/post labelling operationsDaan De Meyer2023-05-311-1/+1
| | | | | | | | | By default, label_ops is initialized with a NULL pointer which translates to noop labelling operations. In mac_selinux_init() and the new mac_smack_init(), we initialize label_ops with a MAC specific LabelOps pointer. We also introduce mac_init() to initialize any configured MACs and replace all usages of mac_selinux_init() with mac_init().

* locale: when no xvariant match select the entry with an empty xvariantFranck Bui2023-04-262-1/+45
| | | | | | When doing a conversion and the specified 'xc->xvariant' has no match, select the x11 layout entry with a matching layout and an empty xvariant if such entry exists. It's still better than no conversion at all.
* locale: convert generated vconsole keymap to x11 layout automaticallyFranck Bui2023-04-241-5/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing x11->console conversions, find_converted_keymap() searches automatically for a candidate in the converted keymap directory for a given x11 layout. However doing console->x11 conversions, this automatic search is not done hence simple conversion in this direction can't be achieved without populating kbd-model-map with entries for converted keymaps. For example, let's consider "at" layout which is not part of kbd-model-map. The "at" x11 layout has a generated keymap "/usr/share/kbd/keymaps/xkb/at.map.gz". If we configure "at" for the x11 layout, localed is able to automatically find the "at" converted vc layout and the conversion just works : $ localectl set-x11-keymap at $ localectl System Locale: LANG=en_US.UTF-8 VC Keymap: at X11 Layout: at However in the opposite direction, ie when setting the vc keymap to "at", no conversion is done and the x11 layout is not defined: $ localectl set-keymap at $ localectl System Locale: LANG=en_US.UTF-8 VC Keymap: at X11 Layout: (unset) This patch fixes this limitation as the implemenation is relatively simple and it removes the need to populate kbd-model-map with (many) entries for converted keymaps. However the patch doesn't remove the existing entries in kbd-model-map which became unneeded after this change to be on the safe side. Note: by default the automatically generated x11 keyboard configs use keyboard model "microsoftpro" which should be equivalent to "pc105" model but with the internet/media key mapping added.

* localed: fix invalid free after shifting pointers using strstripOlivier Gayot2023-04-071-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After manually editing /etc/locale.gen, calling localectl set-locale sometimes fails. When it fails, the systemd journal shows: systemd-localed: free() / invalid pointer. It turned out that it only fails if some of the uncommented lines in /etc/locale.gen have leading spaces, as in: * C.UTF-8 <= OK * en_US.UTF-8 <= OK * fr_FR.UTF-8 <= NOK After parsing a line from /etc/locale.gen, we use strstrip() to obtain the "trimmed" line (without leading or trailing spaces). However, we store the result of strstrip() in the original pointer containing the untrimmed line. This pointer is later passed to free (this is done automatically using _cleanup_free_). This is a problem because if any leading space is present, the pointer will essentially be shifted from its original value. This will result in an invalid free upon cleanup. The same issue is present in the locale_gen_locale_supported function. Fixed by storing the result of strstrip() in a different pointer.

* basic: add RuntimeScope enumLennart Poettering2023-03-101-1/+1
| | | | | | | | | | | | In various tools and services we have a per-system and per-user concept. So far we sometimes used a boolean indicating whether we are in system mode, or a reversed boolean indicating whether we are in user mode, or the LookupScope enum used by the lookup path logic. Let's address that, in introduce a common enum for this, we can use all across the board. This is mostly just search/replace, no actual code changes.

* localed: skip verification when libxkbcommon is not installedZbigniew Jędrzejewski-Szmek2023-03-081-6/+6
| | | | | | | | | | | | | | | | | | | | | | | When compliled without libxkbcommon, we do no verification and accept the arguments as given. When compliled against with, if dlopen() works, we do the verification. But if dlopen() fails, we would refuse the call and return SD_BUS_ERROR_INVALID_ARGS. 5de344704df64d8f31448f1222432bc87ddcfbef added things this way when converting to dlopen(), but it seems not very useful: it can be expected that when the library is supported but missing at runtime, we degrade softly, and that the behaviour is something inbetween the cases of hard disable at compilation time and full support. But right now we behave more strictly then if disabled at compilation. Change the code to just warn if dlopen fails, but accept the arguments. (There are various minimization scenarios where forcing the installation of libxkbcommon is not useful. E.g. a small installation where we want to set the keymap via logind, but the configuration is managed by a configuration management system and is known to be valid. Verification via libxkbcommon is just overhead in this case.) 800f65f827c9828d4c872d44b19ca8a008505690 moved the check earlier, so now even a noop case of setting the values that were already in place can fail. C.f. https://bugzilla.redhat.com/show_bug.cgi?id=2175244.
