Fixes #5452.
2017-02-02fs-util: unify code we use to check if dirent's d_name is "." or ".."Lennart Poettering
We use different idioms at different places. Let's replace this is the one true new idiom, that is even a bit faster...

2016-12-21gpt-auto-generator: enable auto-discovery logic also for verity root file ↵Lennart Poettering
systems verity block devices have two backing devices: the data partition and the hash partition. Previously the gpt auto-discovery logic would refuse working on devices with multiple backing devices, losen this up a bit, to permit them as long as the backing devices are all located on the same physical media.
2016-12-21verity: add support for setting up verity-protected root disks in the initrdLennart Poettering
This adds a generator and a small service that will look for "roothash=" on the kernel command line and use it for setting up a very partition for the root device. This provides similar functionality to nspawn's existing --roothash= switch.
2016-12-21gpt-auto-discovery: port to dissect-image.c dissectorLennart Poettering
Change the gpt auto discovery generator to use the same dissector as nspawn and the rest of the tools. This removes the separate dissector code that the generator previously had and unifies the relevant code.
2016-12-21gpt-auto-generator: drop duplicate container checkLennart Poettering
We already check for containers early in main(), no need to do this check again.
2016-12-21gpt-auto-generator: support LUKS encrypted root partitionsLennart Poettering
Previously, we supported GPT auto-discovery for /home and /srv, but not for the root partition. Add that, too. Fixes: #859

2016-12-21util-lib: various improvements to kernel command line parsingLennart Poettering
This improves kernel command line parsing in a number of ways: a) An kernel option "foo_bar=xyz" is now considered equivalent to "foo-bar-xyz", i.e. when comparing kernel command line option names "-" and "_" are now considered equivalent (this only applies to the option names though, not the option values!). Most of our kernel options used "-" as word separator in kernel command line options so far, but some used "_". With this change, which was a source of confusion for users (well, at least of one user: myself, I just couldn't remember that it's systemd.debug-shell, not systemd.debug_shell). Considering both as equivalent is inspired how modern kernel module loading normalizes all kernel module names to use underscores now too. b) All options previously using a dash for separating words in kernel command line options now use an underscore instead, in all documentation and in code. Since a) has been implemented this should not create any compatibility problems, but normalizes our documentation and our code. c) All kernel command line options which take booleans (or are boolean-like) have been reworked so that "foobar" (without argument) is now equivalent to "foobar=1" (but not "foobar=0"), thus normalizing the handling of our boolean arguments. Specifically this means systemd.debug-shell and systemd_debug_shell=1 are now entirely equivalent. d) All kernel command line options which take an argument, and where no argument is specified will now result in a log message. e.g. passing just "systemd.unit" will no result in a complain that it needs an argument. This is implemented in the proc_cmdline_missing_value() function. e) There's now a call proc_cmdline_get_bool() similar to proc_cmdline_get_key() that parses booleans (following the logic explained in c). f) The proc_cmdline_parse() call's boolean argument has been replaced by a new flags argument that takes a common set of bits with proc_cmdline_get_key(). g) All kernel command line APIs now begin with the same "proc_cmdline_" prefix. h) There are now tests for much of this. Yay!
2016-12-20gpt-auto-generator: rename add_boot() → add_esp()Lennart Poettering
After all, the call doesn't necessarily mount /boot anymore, but possibly /efi now.
2016-12-01tree-wide: stop using canonicalize_file_name(), use chase_symlinks() insteadLennart Poettering
Let's use chase_symlinks() everywhere, and stop using GNU canonicalize_file_name() everywhere. For most cases this should not change behaviour, however increase exposure of our function to get better tested. Most importantly in a few cases (most notably nspawn) it can take the correct root directory into account when chasing symlinks.

2016-10-23tree-wide: drop NULL sentinel from strjoinZbigniew Jędrzejewski-Szmek
This makes strjoin and strjoina more similar and avoids the useless final argument. spatch -I . -I ./src -I ./src/basic -I ./src/basic -I ./src/shared -I ./src/shared -I ./src/network -I ./src/locale -I ./src/login -I ./src/journal -I ./src/journal -I ./src/timedate -I ./src/timesync -I ./src/nspawn -I ./src/resolve -I ./src/resolve -I ./src/systemd -I ./src/core -I ./src/core -I ./src/libudev -I ./src/udev -I ./src/udev/net -I ./src/udev -I ./src/libsystemd/sd-bus -I ./src/libsystemd/sd-event -I ./src/libsystemd/sd-login -I ./src/libsystemd/sd-netlink -I ./src/libsystemd/sd-network -I ./src/libsystemd/sd-hwdb -I ./src/libsystemd/sd-device -I ./src/libsystemd/sd-id128 -I ./src/libsystemd-network --sp-file coccinelle/strjoin.cocci --in-place $(git ls-files src/*.c) git grep -e '\bstrjoin\b.*NULL' -l|xargs sed -i -r 's/strjoin\((.*), NULL\)/strjoin(\1)/' This might have missed a few cases (spatch has a really hard time dealing with _cleanup_ macros), but that's no big issue, they can always be fixed later.
2016-10-22tree-wide: make parse_proc_cmdline() strip "rd." prefix automaticallyZbigniew Jędrzejewski-Szmek
This stripping is contolled by a new boolean parameter. When the parameter is true, it means that the caller does not care about the distinction between initrd and real root, and wants to act on both rd-dot-prefixed and unprefixed parameters in the initramfs, and only on the unprefixed parameters in real root. If the parameter is false, behaviour is the same as before. Changes by caller: log.c (systemd.log_*): changed to accept rd-dot-prefix params pid1: no change, custom logic cryptsetup-generator: no change, still accepts rd-dot-prefix params debug-generator: no change, does not accept rd-dot-prefix params fsck: changed to accept rd-dot-prefix params fstab-generator: no change, custom logic gpt-auto-generator: no change, custom logic hibernate-resume-generator: no change, does not accept rd-dot-prefix params journald: changed to accept rd-dot-prefix params modules-load: no change, still accepts rd-dot-prefix params quote-check: no change, does not accept rd-dot-prefix params udevd: no change, still accepts rd-dot-prefix params I added support for "rd." params in the three cases where I think it's useful: logging, fsck options, journald forwarding options.
2016-10-22tree-wide: allow state to be passed through to parse_proc_cmdline_itemZbigniew Jędrzejewski-Szmek
No functional change.

2016-07-21gpt-generator: relax EFI check a bitLennart Poettering
Previously, we'd not mount the ESP except on EFI boots, and only when the ESP used for booting matches the ESP we found. With this change on non-EFI boots we'll mount a discovered ESP anyway, and on EFI boots we'll only mount it if it matches the ESP we booted from.
2016-07-21gpt-generator: use /efi as mount point for the ESP if it existsLennart Poettering
Let's make the EFI generator a bit smarter: if /efi exists it is used as mount point for the ESP, otherwise /boot is used. This should increase compatibility with distros which use legacy boot loaders that insist on having /boot as something that isn't the ESP.
2016-05-12Create initrd-root-device.target synchronization point (#3239)Daniel Drake
Add a synchronization point so that custom initramfs units can run after the root device becomes available, before it is fsck'd and mounted. This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-02-03gpt-auto: handle errors from blkid more correctlyLennart Poettering
Let's make sure we don't choke if blkid_probe_lookup_value() returns a NULL string. Also, make sur we propagate the correct error when blkid_probe_lookup_value() fails.

2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-10-06gpt-auto-generator: fix duplicate backing partition checkLennart Poettering
We shouldn't exit the loop early, otherwise our duplicate backing partition check won't work.
2015-09-30gpt-auto-generator: check fstab for /boot entriesKay Sievers
We need to prevent the creation of the gpt automount unit, which will not get overridden by the fstab mount unit. https://github.com/systemd/systemd/issues/1378
2015-09-08gpt-auto: fix ESP options and descriptionMarius Thesing
Since 59512f21 the parameters were passed in the wrong order, causing the options to be interpreted as the description. Also, while "false" was supposed to be passed for "rw", the ESP should actually be mounted read-write. It just happened to be "true" since the description char* was passed for "rw".
2015-09-07basic: rework virtualization detection APILennart Poettering
Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.
2015-09-07gpt-auto: minor simplificatin handling the no-auto GPT flagLennart Poettering
Let's query the flags only once, and document why we ignore it for the ESP.
2015-09-07gpt-auto: try to handle LUKS root partitions betterLennart Poettering
If the root file system is located on an encrypted root disk, we'll not find the GPT partition table for it. Let's fix that by following the slaves/ symlinks in /sys for the device. We only handle devices having exactly one backing device. Also see: #1167

add_automount() was only used on EFI systems, compile it conditionally to avoid the warning.
2015-08-11gpt-auto-generator: apply partition-type flags only to specific partition-typesKay Sievers
The partition-type flags are defined independently for every partition-type. Apply them only to the types where they are defined, and not to the ESP, which does not appear to share the same set of flags. https://github.com/systemd/systemd/issues/920

Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.
