Discoverable Partitions Specification
|
|
|
|
Input devices like rudders or pedals are joystick-like; they don't have
buttons, but axes like RX, THROTTLE, or RUDDER. These don't interfere with
other device types with absolute axes (touch screens, touchpads, and
accelerometers), so it's fairly safe to mark them as ID_INPUT_JOYSTICK and thus
hand out dynamic ACLs to the user.

Since the index is already post-incremented when the array is appended
to, this assertion can be wrongly reached when the array is at capacity
(with the NULL terminator). The bug is reproducible on shutdown with
the following settings in /etc/systemd/system.conf:
LogTarget=journal-or-kmsg
LogColor=yes
LogLocation=yes

Fixup for 76800848f281c3 'networkd: link - degrade failed UP to warning'.
|
|
For large values of item->size, the 'part' pointer can wrap around,
which results in an illegal pointer, but currently passes the for-loop
condition.

Instead of iterating through the list of partitions and probing them all
with blkid, simply probe the partition table and use that information to
only probe the partitions we care for.
|
|
Something else may still bring the link up, so don't enter failed state prematurely.

|
Bring some arrays that are used for DEFINE_STRING_TABLE_LOOKUP() in the
same order than the enums they reference.
Also, pass the corresponding _MAX value to the array initalizer where
appropriate.

Activator connections may upload policy when registering to the bus.
This patch contains code to translate between BusNamePolicy objects and
the kdbus specific items.
|
|
Bring kdbus.h in sync with recent policy related changes. Most notably,
KDBUS_MAKE_POLICY_OPEN is now gone. The rest doesn't matter for systemd
at this point, as the policy functionality was not yet used.
|
|
There are three directives to specify bus name polices in .busname
files:
* AllowUser [username] [access]
* AllowGroup [groupname] [access]
* AllowWorld [access]
Where [access] is one of
* 'see': The user/group/world is allowed to see a name on the bus
* 'talk': The user/group/world is allowed to talk to a name
* 'own': The user/group/world is allowed to own a name

This patch introduces reading ethernet address and IPV4/IPv6
as well which is based on table based look up.
[tomegun: rename read_ether() to read_ether_addr() to match the append function.]

When the manager receives a SIGUSR2 signal, it opens a memory stream
with open_memstream(), uses the returned file handle for logging, and
dumps the logged content with log_dump().
However, the char* buffer is only safe to use after the file handle has
been flushed with fflush, as the man pages states:
When the stream is closed (fclose(3)) or flushed (fflush(3)), the
locations pointed to by ptr and sizeloc are updated to contain,
respectively, a pointer to the buffer and the current size of the
buffer.
These values remain valid only as long as the caller performs no
further output on the stream. If further output is performed, then the
stream must again be flushed before trying to access these variables.
Without that call, dump remains NULL and the daemon crashes in
log_dump().
|

|
|
When a busname unit enters BUSNAME_FAILURE_SERVICE_FAILED_PERMANENT, the
serialization will not be able to look up the result as string via
busname_result_to_string(). This leads to an assertion trap during
daemon-reexec.

When run in an initrd and no root= argument is set (or is set to
root=gpt-auto) we will automatically look for the root partition on the
same disk the EFI ESP is located on.
Since we look for swap, /home and /srv on the disk the root partition is
located on, we hence have a fully discoverable chain:
Firmware discovers the EFI ESP partition → the initrd discovers the
root partition → the host OS discovers swap, /home, and /srv.
Note that this requires an EFI boot loader that sets the
LoaderDevicePartUUID EFI variable, such as Gummiboot.

same disk as the ESP, expose a property on the udev device
This is preparation for a logic to automatically discover the root
partition to boot from if no partition has been configured explicitly.
This makes use of our newly defined GPT type GUIDs for our root disks:
#define GPT_ROOT_X86 SD_ID128_MAKE(44,47,95,40,f2,97,41,b2,9a,f7,d1,31,d5,f0,45,8a)
#define GPT_ROOT_X86_64 SD_ID128_MAKE(4f,68,bc,e3,e8,cd,4d,b1,96,e7,fb,ca,f9,84,b7,09)
We define differen GUIDs for different architectures to allow images
which finde the right root partition for the appropriate arch.

With the new sd_rtnl_message_read_string(), there is no longer a need for
rtnl_message_get_ifname().
|
|
This patch introduces new netlink attribute parsing logic
which is table based lookup and sd_rtnl_message_read_*
methods for reading attributes. By doing this user does not
have to loop for the attribute values . Only providing the
attribute type it gets the attribute values which is optimized
and sd_rtnl_message_read_* methods are simplified.

In addition to checking whether the diestination mount point is
populated, check whether it is already a mount point.
If it is already a mount point, or if it is unpopulated, let's create
the unit.
|

|
|
Already split variable assignments before invoking the callback. And
drop "rd." settings if we are not in an initrd.

- Add support for finding and mounting /srv based on GPT data, similar
to how we already handly /home.
- Share the fsck logic between GPT, EFI and fstab generators
- Make sure we never run the EFI generator inside containers
- Drop DefaultDependencies=no from EFI mount units
- Other fixes

Bridges will change their MAC address when other devices are enslaved. We need
the correct MAC address to acquire a DHCP lease, so take note of it whenever
it changes.
