2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.

a single user so far.
2015-02-01Add a snprinf wrapper which checks that the buffer was big enoughZbigniew Jędrzejewski-Szmek
If we scale our buffer to be wide enough for the format string, we should expect that the calculation was correct. char_array_0() invocations are removed, since snprintf nul-terminates the output in any case. A similar wrapper is used for strftime calls, but only in timedatectl.c.
2014-12-24sd-bus: rename sd_bus_open_system_container() to sd_bus_open_system_machine()Lennart Poettering
Pretty much everywhere else we use the generic term "machine" when referring to containers in API, so let's do though in sd-bus too. In particular, since the concept of a "container" exists in sd-bus too, but as part of the marshalling system.
2014-11-28treewide: yet more log_*_errno + return simplificationsMichal Schmidt
Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
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().
2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
2014-07-27core: only set the kernel's timezone when the RTC runs in local timeKay Sievers
We can not reliably manage any notion of local time. Every daylight saving time change or time zone change by traveling will make the time jump, and the local time might jump backwards which creates unsolvable problems with file timestamps. We will no longer tell the kernel our local time zone and leave everything set to UTC. This will effectively turn FAT timestamps into UTC timestamps. If and only if the machine is configured to read the RTC in local time mode, the kernel's time zone will be configured, but systemd-timesysnc will disable the kernel's system time to RTC syncing. In this mode, the RTC will not be managed, and external tools like Windows bootups are expected to manage the RTC's time. https://bugs.freedesktop.org/show_bug.cgi?id=81538
2014-07-07shared: make timezone and locale enumeration and validation genericLennart Poettering
This way we can reuse it other code thatn just localectl/localed + timedatectl/timedated.
2014-04-14timedatectl: avoid using uninitialized varThomas Hindoe Paaboel Andersen
sec is not set if have_time is false so avoid using it. have_time was introduced in 9ff09bcb86fb125768667aca9bc0b10b1745370a but only the first uses for sec were covered Found with scan-build

Which does have TimeUSec. Should we specifically check for this method instead of assuming time=0 means it doesn't exist?

2013-12-10bus: introduce "trusted" bus concept and encode access control in object vtablesLennart Poettering
Introduces a new concept of "trusted" vs. "untrusted" busses. For the latter libsystemd-bus will automatically do per-method access control, for the former all access is automatically granted. Per-method access control is encoded in the vtables: by default all methods are only accessible to privileged clients. If the SD_BUS_VTABLE_UNPRIVILEGED flag is set for a method it is accessible to unprivileged clients too. By default whether a client is privileged is determined via checking for its CAP_SYS_ADMIN capability, but this can be altered via the SD_BUS_VTABLE_CAPABILITY() macro that can be ORed into the flags field of the method. Writable properties are also subject to SD_BUS_VTABLE_UNPRIVILEGED and SD_BUS_VTABLE_CAPABILITY() for controlling write access to them. Note however that read access is unrestricted, as PropertiesChanged messages might send out the values anyway as an unrestricted broadcast. By default the system bus is set to "untrusted" and the user bus is "trusted" since per-method access control on the latter is unnecessary. On dbus1 busses we check the UID of the caller rather than the configured capability since the capability cannot be determined without race. On kdbus the capability is checked if possible from the attached meta-data of a message and otherwise queried from the sending peer. This also decorates the vtables of the various daemons we ship with these flags.

This way, timedatectl can be run over the network and determine all properties correctly from the server rather than the client.
2013-07-02man: improve grammar and word formatting in numerous man pagesJason St. John
Use proper grammar, word usage, adjective hyphenation, commas, capitalization, spelling, etc. To improve readability, some run-on sentences or sentence fragments were revised. [zj: remove the space from 'file name', 'host name', and 'time zone'.]
2013-06-09Allow for the use of @ in remote host callsDaniel Wallace
Without this you have to use %40 with the -H flag because dbus doesn't like the @ sign being unescaped.
2013-05-23Fix --no-ask-passwordJan Janssen
POSIX_ME_HARDER mode is disabled for localectl. It doesn't make much sense in case of localectl, and there's little reason for localectl to behave specially.

2013-04-05Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek
Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.
