Suspend to disk works for swap files too (even if it is located
on an ecrypted file system):

reboot syscall can be performed with an additional argument. In some
systems this functionality can be useful to modify the mode of the
next boot performed by the bootloader.

To write useful bus code clients need to validate utf8 frequently since
the bus reacts allergic to it. Since glibc does not provide any calls
for this, let's provide it as part of libsystemd-bus.

zero-copy network IO
This also drops --ignore-env, which can't really work anymore if we
allow multiple fds. Also adds support for pretty printing of peer
identities for debug purposes, and abstract namespace UNIX sockets. Also
ensures that we never take more connections than a certain limit.
|
|
Among other things this makes sure we set SO_REUSEADDR which is
immensely useful.

|
Instead of individually checking for containers in each user do this
once in a new call proc_cmdline() that read the file only if we are not
in a container.
|

|
|
Should fix linking with old toolchain.
|
|
Move this to src/share/net-util.c, so it can be used elsewhere.

detect_container()
After all, we ended up calling detect_container() more often than
detect_virtualization(), hence the former one should cache the results,
since the latter is only a wrapper around the former.

This allow querying the RTC time from the unprivileged timedatectl.

array from stdarg function parameters
This allows us to turn lists of strings passed in easily into string
arrays without having to allocate memory.
|
|
There is no point in keeping one timestamp for each directory, as we only
ever care about the most recent one.

Parses a whitespace separated list of strings into a vector of enums.

This introduces a new key NamePolicy, which takes an ordered list of naming
policies. The first successful one is applide. If all fail the value of Name
(if any) is used.
The possible policies are 'onboard', 'slot', 'path' and 'mac'.
This patch introduces a default link file, which replaces the equivalent udev
rule.

The indentation was wrong, also put the semicolon on a separate line to make it clear it is a for-loop
with an epmyt body.
|
|
I want to use this from a bulitin in a subsequent patch.
|
|
Otherwise, the user would have to manually initialize the pointer. Nobody currently uses this code,
so the change in behaviour sohuld be fine.

-Og Optimize debugging experience. -Og enables optimizations that do
not interfere with debugging. It should be the optimization level of
choice for the standard edit-compile-debug cycle, offering a
reasonable level of optimization while maintaining fast compilation
and a good debugging experience.

maximum
Messages with log levels above the current maximum log level will be dropped
inside log_meta(). But to be able to call the function, all parameters for
the function need to be provided. This can easily get expensive, if values
need to be calculated or functions are used in parameters.
Avoid all useless work by checking inside the macro, before we look
at any parameters passed to the logging functions.

When set to 0 this will stop tools like the backlight and rfkill tools to
restore state from previous boot. This is useful in case the stored state
is bogus to the extent that it is preventing you from resetting it (e.g.,
the backlight settings cause the screen to be off on boot on a system where
the backlight can not be adjusted directly from the keyboard).
|
|
This way, timedatectl can be run over the network and determine all
properties correctly from the server rather than the client.
|
|
Always use our own macros, and name all our own macros the same style.
|
|
This function should get the same treatment as other qsort uses
did in 7ff7394 "Never call qsort on potentially NULL arrays".

glob_extend() would completely fail to work, or return incorrect
data if it wasn't being passed the current getopt "optarg" variable
as it used the global variable, instead of the passed parameters.
|
|
each invocation
We can determine the list entry type via the typeof() gcc construct, and
so we should to make the macros much shorter to use.

Emacs C indenting really gets confused by these lines if they carry no
trailing semicolon, hence let's make this nicer for good old emacs. The
other macros which define functions already do this too, so let's copy
the scheme here.
Also, let's use an uppercase name for the macro. So far our rough rule
was that macros that are totally not function-like (like this ones,
which define a function) are uppercase. (Well, admittedly it is a rough
rule only, for example function and variable decorators are all
lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and
also they at least got underscore prefixes.) Also, the macros that
define functions that we already have are all uppercase, so let's do the
same here...
