It does not use any functions from libcap directly. The CAP_* constants in use
through this file come from "missing.h" which will import <linux/capability.h>
and complement it with CAP_* constants not defined by the current kernel
headers.
Add an explicit import of our "capability.h" since it does use the function
capability_bounding_set_drop from that header file. Previously, that header was
implicitly imported through through "cap-list.h".
Tested that "systemd-nspawn" builds cleanly and works after this change.

In any case, the compiler generates the same code inline and never
actually calls the library function.

The new test-cap-list introduced in commit 2822da4fb7f891 uses the included
table of capabilities. However, it uses cap_last_cap() which probes the kernel
for the last available capability. On an older kernel (e.g. 3.10 from RHEL 7)
that causes the test to fail with the following message:
Assertion '!capability_to_name(cap_last_cap()+1)' failed at src/test/test-cap-list.c:30, function main(). Aborting.
Fix it by exporting the size of the static table and using it in the test
instead of the dynamic one from the current kernel.
Tested by successfully running ./test-cap-list and the whole `make check` test
suite with this patch on a RHEL 7 host.

We make use of the btrfs subvol crtime for this, and for gpt images of a
manually managed xattr, if we can.

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.
|
|
There is alot of cleanup that will have to happen to turn on
-fstrict-aliasing, but I think our code should be "correct" to the rule.

This way "machinectl login" can be opened up to run without privileges.

Accidentally forgot to commit this. Sorry!

After all, pretty much all our tools include it, and it should hence be
shared.
Also move sysfs-show.h from core/ to login/, since it has no point to
exist in core.

on a pty and returns the pty master fd to the client
This is a one-stop solution for "machinectl login", and should simplify
getting logins in containers.

files from core
Stuff in src/shared or src/libsystemd should *never* include code from
src/core or any of the tools, so don't do that here either. It's not OK!

sd_bus_creds_get_well_known_names() fails with -ENODATA in case the
message has no names attached, which is intended behavior if the
remote connection didn't own any names at the time of sending.
The function already deals with 'sender_names' being an empty strv,
so we can just continue in such cases.
|
|
Messages to destinations that are not currently owned by any bus connection
will cause kdbus related function to return with either -ENXIO or -ESRCH.
Such conditions should not make the proxyd terminate but send a sane
SD_BUS_ERROR_NAME_HAS_NO_OWNER error reply to the proxied connection.
|

For that, ask machined for a container PTY and use that.

Then, port "machinectl" over to make use of it.

I figure "pull-dck" is not a good name, given that one could certainly
read the verb in a way that might be funny for 16year-olds. ;-)
Also, don't hardcode the index URL to use, make it runtime and configure
time configurable instead.

We originally only supported escaping ucs2 encoded characters (as \uxxxx). This
only covers the BMP. Support escaping also utf16 surrogate pairs (on the form
\uxxxx\uyyyy) to cover all of unicode.
|
|
We originally only supported the BMP (i.e., we treated UTF-16 as UCS-2).
|
|
Originally we only supported ucs2, so move the ucs4 version from libsystemd-terminal to shared
and use that everywhere.

Kernel notifications carry a timestamp now, so make sure
bus_kernel_translate_message() doesn't complain when it stumbles across
them.

The KDBUS_CMD_FREE ioctl struct has a size field now, which needs to be set.

Sync kdbus.h with upstream changes:
* Two optional cancellation points where added for synchronously
blocking KDBUS_CMD_SEND commands: A sigmask to change the mask
of accepted signals before the task is put to sleep, and a
generic file descriptor that can be written to, in order to cancel
the command. Both methods are currently unused.
* The KDBUS_CMD_CANCEL ioctl was removed. sd-bus was never using
that command, so there's no change needed.
* Some kerneldoc fixes
|
|
* (potentially) public headers must reside in src/systemd/ (not in
src/libsystemd*)
* some private (not prefixed with sd_) functions moved from sd-lldp.h to
lldp-internal.h
* introduce lldp-util.h for the cleanup macro, as these should not be public
* rename the cleanup macro, we always name them _cleanup_foo_, never
_cleanup_sd_foo_
* mark some function arguments as 'const'

hidden_file() is a bit more precise, since dot files usually shouldn't
be ignored, but certainly be considered hidden.
