2017-03-01udev: Use parent bus id for virtio disk builtin path-id (#5500)Viktor Mihajlovski
The builtin path id for virtio block devices has been changed to use the bus id without a prefix "virtio-pci" to be compatible with all virtio transport types. In order to not break existing setups, the by-path symlinks for virtio block devices on the PCI bus are reintroduced by udev rules. The virtio-pci symlinks are considered to be deprecated and should be replaced by the native PCI symlinks. Example output for a virtio disk in PCI slot 7: $ ls /dev/disk/by-path pci-0000:00:07.0 pci-0000:00:07.0-part1 virtio-pci-0000:00:07.0 virtio-pci-0000:00:07.0-part1 See also [1] https://lists.freedesktop.org/archives/systemd-devel/2017-February/038326.html [2] https://lists.freedesktop.org/archives/systemd-devel/2017-March/038397.html This reverts f073b1b but keeps the same symlinks for compatibility.

2017-02-17udev: fix id_net_name_path for virtio-ccw interfaces (#5357)Viktor Mihajlovski
The CCW id_net_name_path detection didn't account for virtio interfaces on the CCW bus. As a result the default interface names for virtio-ccw interfaces would use the old eth<x> format instead of enc<busid>. Since virtio-pci interface naming follows the naming rules of the parent bus, the names_ccw() logic was changed to apply the CCW interface naming rules to virtio interfaces as well, e.g. enc2000 for an interface with a CCW bus id 0.0.2000. As virtio interfaces are apt to get the otherwise unusual CCW bus id 0.0.0000, the last '0' is now preserved in this case. The virtio subsystem skipping loop has been moved from names_pci() into a function skip_virtio() that can be reused for all bus types with virtio network devices. Since virtio-ccw interfaces use single CCW addresses the ccwgroup requirement was relaxed and the C definitions were changed accordingly.
2017-02-17udevd: use signal_to_string() instead of strsignal() at one placeLennart Poettering
strsignal() sucks, as it tries to generate human readable strings from something that isn't really human readable by concept. Let's use signal_to_string() instead, making this more grokkable. Difference is: SIGINT gets translated → "SIGINT" rather than → "Interrupted".
2017-01-27udev-event: use in-place whitespace replacementDan Streetman
Instead of using a temp buffer to replace whitespace in variable substitutions, just allow util_replace_whitespace to replace in-place. Add a comment to util_replace_whitespace indicating it is used to replace in-place, to prevent accidental future breakage.

2017-01-03udev-rules: perform whitespace replacement for symlink subst valuesDan Streetman
If the string_escape option is either unset or 'replace' (i.e. if it is not 'none'), then enable whitespace replacement in SYMLINK variable substitution values, as added in the last patch. This will keep any whitespace that is directly contained in a SYMLINK value, but will replace any whitespace that is added to the SYMLINK value as a result of variable substitution (except $result/%c). This fixes bug 4833.
2017-01-03udev-event: add replace_whitespace param to udev_event_apply_formatDan Streetman
If replace_whitespace is true, each substitution value has all its whitespace removed/replaced by util_replace_whitespace (except the SUBST_RESULT substitution - $result{} or %c{} - which handles spaces itself as field separators). All existing callers are updated to pass false, so no functional change is made by this patch. This is needed so the SYMLINK assignment can replace any spaces introduced through variable substitution, becuase the SYMLINK value is a space-separated list of symlinks to create. Any variables that contain spaces will thus unexpectedly change the symlink value from a single symlink to multiple incorrectly-named symlinks. This is used in the next patch, which enables the whitespace replacement for SYMLINK variable substitution.
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!

2016-12-01Spot inconsistent quoting (just one single quote) (#4732)Tobias Stoeckmann
It is possible to specify only one quote in udev rules, which is not detected as an invalid quoting (" instead of "" for empty string). Technically this doesn't lead to a bug, because the string ends in two terminating nul characters at this position, but a user should still be reminded that his configuration is invalid.

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.

2016-10-06sd-device/networkd: unify code to get a socket for issuing netdev ioctls onLennart Poettering
As suggested here: https://github.com/systemd/systemd/pull/4296#issuecomment-251911349 Let's try AF_INET first as socket, but let's fall back to AF_NETLINK, so that we can use a protocol-independent socket here if possible. This has the benefit that our code will still work even if AF_INET/AF_INET6 is made unavailable (for exmple via seccomp), at least on current kernels.

2016-07-20core: when forcibly killing/aborting left-over unit processes log about itLennart Poettering
Let's lot at LOG_NOTICE about any processes that we are going to SIGKILL/SIGABRT because clean termination of them didn't work. This turns the various boolean flag parameters to cg_kill(), cg_migrate() and related calls into a single binary flags parameter, simply because the function now gained even more parameters and the parameter listed shouldn't get too long. Logging for killing processes is done either when the kill signal is SIGABRT or SIGKILL, or on explicit request if KILL_TERMINATE_AND_LOG instead of LOG_TERMINATE is passed. This isn't used yet in this patch, but is made use of in a later patch.
