* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* When mangling names, optionally emit a warning (#8400)Zbigniew Jędrzejewski-Szmek2018-03-211-2/+2
| | | | | | | | | | | | | | | | | | The warning is not emitted for absolute paths like /dev/sda or /home, which are converted to .device and .mount unit names without any fuss. Most of the time it's unlikely that users use invalid unit names on purpose, so let's warn them. Warnings are silenced when --quiet is used. $ build/systemctl show -p Id hello@foo-bar/baz Invalid unit name "hello@foo-bar/baz" was escaped as "hello@foo-bar-baz" (maybe you should use systemd-escape?) Id=hello@foo-bar-baz.service $ build/systemd-run --user --slice foo-bar/baz --unit foo-bar/foo true Invalid unit name "foo-bar/foo" was escaped as "foo-bar-foo" (maybe you should use systemd-escape?) Invalid unit name "foo-bar/baz" was escaped as "foo-bar-baz" (maybe you should use systemd-escape?) Running as unit: foo-bar-foo.service Fixes #8302.
* log: remove LOG_TARGET_SAFE pseudo log targetLennart Poettering2018-01-241-1/+2
| | | | | | | | | | | | | This removes LOG_TARGET_SAFE. It's made redundant by the new "prohibit-ipc" logging flag, as it used to have a similar effect: avoid logging to the journal/syslog, i.e. any local services in order to avoid deadlocks when we lock from PID 1 or its utility processes (such as generators). All previous users of LOG_TARGET_SAFE are switched over to the new setting. This makes things a bit safer for all, as not even the SYSTEMD_LOG_TARGET env var can be used to accidentally log to the journal anymore in these programs.
* Add SPDX license identifiers to source files under the LGPLZbigniew Jędrzejewski-Szmek2017-11-191-0/+1
| | | | | This follows what the kernel is doing, c.f. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5fd54ace4721fc5ce2bb5aef6318fcf17f421460.

* util-lib: various improvements to kernel command line parsingLennart Poettering2016-12-211-32/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!
* debug-generator: simplify handling of arg_default_unitZbigniew Jędrzejewski-Szmek2016-12-171-8/+4
| | | | Also free the allocated memory before exiting.
* tree-wide: drop NULL sentinel from strjoinZbigniew Jędrzejewski-Szmek2016-10-231-2/+2
| | | | | | | | | | | | | 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.
* tree-wide: make parse_proc_cmdline() strip "rd." prefix automaticallyZbigniew Jędrzejewski-Szmek2016-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* tree-wide: allow state to be passed through to parse_proc_cmdline_itemZbigniew Jędrzejewski-Szmek2016-10-221-2/+2
| | | | No functional change.
* tree-wide: remove Emacs lines from all filesDaniel Mack2016-02-101-2/+0
| | | | | This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

* util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering2015-10-241-0/+1
| | | | | | | | | | | | | | 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.
* tree-wide: update empty-if coccinelle script to cover empty-while and moreLennart Poettering2015-09-091-4/+2
| | | | Let's also clean up single-line while and for blocks.
* tree-wide: make use of log_error_errno() return value in more casesLennart Poettering2015-09-091-4/+6
| | | | | | | The previous coccinelle semantic patch that improved usage of log_error_errno()'s return value, only looked for log_error_errno() invocations with a single parameter after the error parameter. Update the patch to handle arbitrary numbers of additional arguments.
* core: rework unit name validation and manipulation logicLennart Poettering2015-05-051-6/+6
| | | | | | | | | | | | | | | A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
* treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt2014-11-281-2/+2
| | | | | | | | | | | If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
* treewide: no need to negate errno for log_*_errno()Michal Schmidt2014-11-281-1/+1
| | | | It corrrectly handles both positive and negative errno values.
* treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt2014-11-281-1/+1
| | | | | | | | | | | | | As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
* util: simplify proc_cmdline() to reuse get_process_cmdline()Lennart Poettering2014-11-071-2/+3
| | | | Also, make all parsing of the kernel cmdline non-fatal.
* debug-generator: add new kernel cmdline option systemd.wants= to add units ↵Lennart Poettering2014-06-201-17/+53
| | | | to the initial transaction
* debug-generator: add new generatorLennart Poettering2014-06-192-0/+138
debug-generator can mask specific units if they are specified on the kernel command line with systemd.mask=. debug-generator can pull in debug-shell.service is systemd.debug-shell is passed on the kernel command line.
