Instead of adjusting job timeouts in the core, let fstab-generator
write out a dropin snippet with the appropriate JobTimeout.
x-systemd-device.timeout option is removed from Options= line
in the generated unit.
The functions to write dropins are moved from core/unit.c to
shared/dropin.c, to make them available outside of core.
generator.c is moved to libsystemd-label, because it now uses
functions defined in dropin.c, which are in libsystemd-label.

This allows us to bootup a rootfs with a /usr directory only.

shifting from a non fixed number of bits >= to the size of the type
leads to weird results, handle the special case of << 32 to fix it.
This was causing a test failure from test-socket-util:
Assertion 'in_addr_prefix_intersect(f, &ua, apl, &ub, bpl) == result' failed at
/var/tmp/paludis/build/sys-apps-systemd-scm/work/systemd-scm/src/test/test-socket-util.c:147, function
test_in_addr_prefix_intersect_one(). Aborting.
Minimal reproducer:
paludisbuild@Lou /tmp $ cat test.c
static void test(unsigned m) {
unsigned nm = 0xFFFFFFFFUL << (32-m);
printf("%u: %x\n", m, nm);
}
int main (void) {
test(1);
test(0);
return 0;
}
paludisbuild@Lou /tmp $ gcc -m32 -std=gnu99 test.c -o test32
paludisbuild@Lou /tmp $ ./test32

0: ffffffff
paludisbuild@Lou /tmp $ gcc -std=gnu99 test.c -o test64
paludisbuild@Lou /tmp $ ./test64

We used to check if e.g. IFLA_BOND_MAX is defined and provide fallback
values in missing.h is it wasn't. But over time, various kernel
versions added IFLA_* defines, so checking for IFLA_BOND_MAX is not
enough if the kernel is new enough to have some of them but too old to
have all. In case we detect that the latest known enum value is
missing, #define most of them.

Update for the current behavior of path_strv_resolve which now returns
paths relative to the given root, not the full absolute paths.
|
|
This restores the original root handling logic that was present prior to
112cfb18 when path expansion moved to path_strv_canonicalize_absolute.
That behavior partially went away in 12ed81d9.
Alternatively all users of conf_files_list* could be updated to
concatenate the paths themselves as unit_file_query_preset did but since
no user needs the un-concatenated form that is pointless duplication.
|
|
Since 12ed81d9 path_strv_canonicalize_absolute leaves the search list
relative to the given root directory instead of resolving paths to their
true location as the name implies. To better reflect this behavior
rename to the less strongly worded path_strv_resolve.

The idea was to not fail on, nor to ignore errors from chown()/chmod(),
but to proceed and simply return the most recent error...

Previously it would recursively copy the entire tree in, and descend
into subdirectories even if the destination already exists. Let's do
what the documentation says and not do that.
If files down the tree shall be copied too, they should get their own
"C" lines.

Introduce a new configuration file /etc/systemd/coredump.conf to
configure when to place coredumps in the journal and when on disk.
Since the coredumps are quite large, default to storing them only on
disk.

This is based on parts of similar patches from Michael Marineau and
Lukas Nykrin, but simply uses strappenda3().

|

The DefaultInstance= name is used when enabling template units when only
specifying the template name, but no instance.
Add DefaultInstance=tty1 to getty@.service, so that when the template
itself is enabled an instance for tty1 is created.
This is useful so that we "systemctl preset-all" can work properly,
because we can operate on getty@.service after finding it, and the right
instance is created.

only after traversing all search directories
Let's always make sure to look in all search directories for the full
unit names first, before looking for templates for them.

do all-unit preset operations
The new "systemctl preset-all" command may now be used to put all
installed units back into the enable/disable state the vendor/admin
encoded in preset files.
Also, introduce "systemctl --preset-mode=enable-only" and "systemctl
--preset-mode=disable-only" to only apply the enable or only the disable
operations of a "systemctl preset" or "systemctl preset-all" operation.
"systemctl preset-all" implements this RFE:

We need to check for the last dot, not the first one in a unit name, for
the suffix. Correct that.

This is similar to malloc_multiply() and friends. It is realloc() with a
multiplication-overflow check.
|
|
Passing 0 to malloc() is not required to return NULL. Therefore, don't
bail out if "b" is 0. This is not of importance to the existing helpers,
but the upcoming realloc_multiply() requires this. To keep consistence, we
keep the same behavior for the other helpers.
|

As it turns out, we cannot use _Pragma in compound-statements. Therefore,
constructs like MIN(MAX(a, b), x) will warn due to shadowed variable
declarations. The DISABLE_WARNING_SHADOW macro can be used to suppress
these.
Note that using UNIQUE(_var) does not work either as GCC uses the last
line of a macro-expansion for __LINE__, therefore, still causing both
macros to have the same variables. We could use different variable-names
for MIN and MAX, but that just hides the problem and still fails for
MIN(something(MIN(a, b)), c).
The only working solution is to use __COUNTER__ and pass it pre-evaluated
as extra argument to a macro to use as name-prefix. This, however, makes
all these macros much more complicated so I'll go with manual
DISABLE_WARNING_SHADOW so far.

destination before creating a symlink
Also, make use of this for mtab as long as mount insists on creating it
even if we invoke it with "-n".

The file should have been in /usr/lib/ in the first place, since it
describes the OS container in /usr (and not the configuration in /etc),
hence, let's support os-release files in /usr/lib as fallback if no
version in /etc exists, following the usual override logic.
A prior commit already enabled tmpfiles to create /etc/os-release as a
symlink to /usr/lib/os-release should it be missing, thus providing nice
compatibility with applications only checking in /etc.
While it's probably a good idea if all apps check both locations via a
fallback logic, it is only necessary in the early boot process, as long
as the /etc/os-release symlink has not been restored, in case we boot
with an empty /etc.
