* basic: split out dev_t related calls into new devno-util.[ch]Lennart Poettering2022-04-132-2/+3
| | | | | | | | | | | | | | No actual code changes, just splitting out of some dev_t handling related calls from stat-util.[ch], they are quite a number already, and deserve their own module now I think. Also, try to settle on the name "devnum" as the name for the concept, instead of "devno" or "dev" or "devid". "devnum" is the name exported in udev APIs, hence probably best to stick to that. (this just renames a few symbols to "devum", local variables are left untouched, to make the patch not too invasive) No actual code changes.

This way we don't end up linking a separate copy into various binaries. It would even end up in libsystemd, where it is not needed. (Maybe it'd be removed in some optimization phase, but it's better to not rely on that.) $ grep -l -r -a 'path is not absolute%s' build/ build/libnss_systemd.so.2 build/pam_systemd_home.so build/test-dlopen build/src/basic/libbasic.a.p/path-util.c.o build/src/basic/libbasic.a build/src/shared/libsystemd-shared-249.so build/test-bus-error build/libnss_mymachines.so.2 build/pam_systemd.so build/libnss_resolve.so.2 build/libnss_myhostname.so.2 build/libsystemd.so.0.32.0 build/libudev.so.1.7.2 $ grep -l -r -a 'path is not absolute%s' build/ build/src/shared/libsystemd-shared-251.a.p/parse-helpers.c.o build/src/shared/libsystemd-shared-251.a build/src/shared/libsystemd-shared-251.so No functional change.

| | | | | | | | | | | Same idea as 03677889f0ef42cdc534bf3b31265a054b20a354. No functional change intended. The type of the iterator is generally changed to be 'const char*' instead of 'char*'. Despite the type commonly used, modifying the string was not allowed. I adjusted the naming of some short variables for clarity and reduced the scope of some variable declarations in code that was being touched anyway.

| | | | | | | | Add support for PIN enrollment with TPM2. A new "tpm2-pin" field is introduced into metadata to signal that the policy needs to include a PIN. v2: fix tpm2_make_luks2_json in sd-repart
* tpm2: support policies with PINGrigori Goronzy2022-03-151-1/+1
| | | | | | | | | | | Modify TPM2 authentication policy to optionally include an authValue, i.e. a password/PIN. We use the "PIN" terminology since it's used by other systems such as Windows, even though the PIN is not necessarily numeric. The pin is hashed via SHA256 to allow for arbitrary length PINs. v2: fix tpm2_seal in sd-repart v3: applied review feedback
* meson: do not use split() in file listsZbigniew Jędrzejewski-Szmek2022-03-021-3/+1
| | | | | | | | | | | The approach to use '''…'''.split() instead of a list of strings was initially used when converting from automake because it allowed identical blocks of lines to be used for both, making the conversion easier. But over the years we have been using normal lists more and more, especially when there were just a few filenames listed. This converts the rest. No functional change.

* sd128: export sd_id128_to_uuid_string()Lennart Poettering2022-02-141-11/+11
| | | | | | | | | We expose various other forms of UUID helpers already, i.e. SD_ID128_UUID_FORMAT_STR and SD_ID128_MAKE_UUID_STR(), and we parse UUIDs, hence add a high-level helper for formatting UUIDs too. This doesn't add any new code, it just moves some helpers id128-util.[ch] → sd-id128.[ch], to make them public.
* repart: fix sector size handlingLennart Poettering2022-02-081-80/+132
| | | | | | | | | | | | | | | | | This queries the sector size from libfdisk instead of assuming 512, and uses that when converting from bytes to the offset/size values libfdisk expects. This is an alternative to Tom Yan's #21823, but prefers using libfdisk's own ideas of the sector size instead of going directly to the backing device via ioctls. (libfdisk can after all also operate on regular files, where the sector size concept doesn't necessarily apply the same way.) This also makes the "grain" variable, i.e. how we'll align the partitions. Previously this was hardcoded to 4K, and that still will be the minimum grain we use, but should the sector size be larger than that we'll use the next multiple of the sector size instead.

* | repart: fix free area calculations for unaligned partitionsLennart Poettering2021-11-091-5/+8
| | | | | | | | | | | | To properly detect how much space we have to distribute we need to take into account that both the partition offset and the partition size aren't aligned.
* | repart: don't distribute space after unaligned partitionsLennart Poettering2021-11-091-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we operate on a disk that has a pre-existing unaligned partition (i.e. one that doesn't start on multiple of 4K, or doesn't have a size of multiple 4K), then the amount of space after it to distribute among partitions isn't a multiple of 4K either. So far we might end up passing the remaining fraction to any partition that wanted it, which was usually the first one after it that is newly defined. This then confused the later placement algorithm, since it assumed all partitions we newly allocate were properly aligned but by being extended by the fractional space they wouldn't be anymore. Let's hence fix that by ensuring we never pass space to later partitions so that things wouldn't be aligned anymore. Anything that is left-over then at the very end (i.e. typically exactly the remaining fraction) is added as padding to the existing, unaligned partition, so that it can't confuse anyone.

* tpm2: support RSA primary keys as fallback if TPM2 devices don't support ECCLennart Poettering2021-09-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | Previously, we hardcoded use of ECC as primary keys, since they are much faster (i.e. saving multiple seconds) to do TPM2 operations with. Alas, not all TPM2 chips appear to support ECC. Bummer. Let's hence add a fallback logic: if we can't create an ECC primary key, use an RSA key, and store that fact away. AFIU the security guarantees should be roughly the same, it's just that RSA primary keys is so much slower to work with than ECC. The primary key algorithm is used is stored in the JSON header of LUKS disks, in a new field. If the field is absent we assume to use ECC, to provide full compatibility with old systemd versions. The primary key algorithm is stored in a new field in the credentials file format (in fact, a previously unused zero space is used), too. Hopefully, this should ensure that TPM2 support will "just work" on more systems. Fixes: #20361
* repart: Support volatile-root for finding the root partitionKristian Klausen2021-09-011-12/+29
| | | | | | | | | The automatic logic can't always find the original root partition (ex: if the rootfs is copied to a ext4 fs backed by zram in the initramfs), so we want to support "/run/systemd/volatile-root" which is a symlink to the original root partition. Fix #20610

* Drop the text argument from assert_not_reached()Zbigniew Jędrzejewski-Szmek2021-08-032-2/+2
| | | | | | | | | | | | | | | | | In general we almost never hit those asserts in production code, so users see them very rarely, if ever. But either way, we just need something that users can pass to the developers. We have quite a few of those asserts, and some have fairly nice messages, but many are like "WTF?" or "???" or "unexpected something". The error that is printed includes the file location, and function name. In almost all functions there's at most one assert, so the function name alone is enough to identify the failure for a developer. So we don't get much extra from the message, and we might just as well drop them. Dropping them makes our code a tiny bit smaller, and most importantly, improves development experience by making it easy to insert such an assert in the code without thinking how to phrase the argument.
* tpm2-util: auto-detect supported PCR banksLennart Poettering2021-07-301-2/+3
| | | | | | | | | | | | | | | | | | | Previously, we'd encode PCR policies strictly with the SHA256 PCR bank set. However, as it appears not all hw implement those. Sad. Let's add some minimal logic to auto-detect supported PCR banks: if SHA256 is supported, use that. But if not, automatically fall back to SHA1. This then changes both the LUKS code, and the credentials code to serialize the selected bank, along with the rest of the data in order to make this robust. This extends the LUK2 JSON metadata in a compatible way. The credentials encryption format is modified in an incompatible way however, but given that this is not part of any official release should be OK. Fixes: #20134
