Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which
enforce pointer alignment this fixes crashes when we previously cast an
unaligned array to uint64_t*, and on others this should at least improve
performance as the compiler now aligns these properly.
This also simplifies the code in most cases by getting rid of typecasts. The
only place which we can't change is struct duid's en.id, as that is _packed_
and public API, so we can't enforce alignment of the "id" field and have to
use memcpy instead.

Improve and enhance the path_id udev builtin to correctly handle bus'
available on Linux on z Systems (s390).
Previously, the CCW bus and, in particular, any FCP devices on it, have
been treated separately. This commit integrates the CCW bus into the
device chain loop. FCP devices and their associated SCSI disks are now
handled through the common SCSI handling functions in path_id.
This implies also a change in the naming of the symbolic links created
by udev. So any backports of this commit to existing Linux distribution
must be done with care. If a backport is required, a udev rule must be
created to also create the "old-style" symbolic links.
Apart from the CCW bus, this commit adds bus support for the:
- ccwgroup bus which manages network devices, and
- ap bus which manages cryptographic adapters
- iucv bus which manages IUCV devices on z/VM

[v2] treewide: treatment of errno and other cleanups
|
|
with small manual cleanups for style.
|
|
|
|
Our functions return negative error codes.
Do not rely on errno being set after calling our own functions.

There are more than enough to deserve their own .c file, hence move them
over.

string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

This really deserves its own file, given how much code this is now.
|
|
We don't use that anywhere any more. With the introduction of alias names it
also is not a proper mapping any more as several keys (e. g. KEY_COFFEE and
KEY_SCREENLOCK) have the same numerical mapping.

While it is currently possible to either not set MACAddressPolicy or set
it to a value different from "persistent" or "random", it is not obvious
that a user can do so. Add a policy, "none", which simply retains kernel
MAC addresses (same as not filling in the policy at all) and document it
so that users are aware of this setting.

Enhance matching of TAG keys
|
|
Use %m where previously %s was used together with strerrno().
Fixes: e53fc357a9b "tree-wide: remove a number of invocations of
strerror() and replace by %m"
|
|
The TAG key can be used in rules for event matching. At the moment, it
does not support inequality tests. This patch enhances the key test to
validate the rule if it does not contain a given TAG (by TAG!="value").

Let's clean up our tree a bit, and reduce invocations of the
thread-unsafe strerror() by replacing it with printf()'s %m specifier.

Another Coccinelle script.
|

Let's also clean up single-line while and for blocks.

Coccinelle fixes

Turns this:
r = -errno;
log_error_errno(errno, "foo");
into this:
r = log_error_errno(errno, "foo");
and this:
r = log_error_errno(errno, "foo");
return r;
into this:
return log_error_errno(errno, "foo");
|
|
Replace this:
if (fd >= 0)
safe_close(fd);
by this:
safe_close(fd);
|
|
Replace this:
close(fd);
fd = -1;
write this:
fd = safe_close(fd);
|
|
This replaces this:
free(p);
p = NULL;
by this:
p = mfree(p);
Change generated using coccinelle. Semantic patch is added to the
sources.

This seems to be an oversight from:
707b66c66381c899d7ef640e158ffdd5bcff4deb
We have to return ENODATA instead of ENOENT if a requested entry is
non-present. Also fix the call-site in udev to check for these errors.
|
|
The recent cgroup-rework changed the error code for un-mounted cgroupfs to
ENOEXEC. Make sure udev ignores it just like ENOENT and does not spill
warnings on the screen.

Virtio buses are undeterministically enumerated, so we cannot use them as a basis
for deterministic naming (see bf81e792f3c0). However, we are guaranteed that there
is only ever one virtio bus for every parent device, so we can simply skip over
the virtio buses when naming the devices.

The function "free" is documented in the way that no action shall occur for
a passed null pointer. It is therefore not needed that a function caller
repeats a corresponding check.

This issue was fixed by using the software Coccinelle 1.0.1.

treewide: trivial issues detected by smatch
|
|
The partition-type flags are defined independently for every partition-type. Apply
them only to the types where they are defined, and not to the ESP, which does not
appear to share the same set of flags.

tree-wide: do not return error codes as bool
