Zbigniew Jędrzejewski-Szmek 349cc4a507 build-sys: use #if Y instead of #ifdef Y everywhere
The advantage is that is the name is mispellt, cpp will warn us.

$ git grep -Ee "conf.set\('(HAVE|ENABLE)_" -l|xargs sed -r -i "s/conf.set\('(HAVE|ENABLE)_/conf.set10('\1_/"
$ git grep -Ee '#ifn?def (HAVE|ENABLE)' -l|xargs sed -r -i 's/#ifdef (HAVE|ENABLE)/#if \1/; s/#ifndef (HAVE|ENABLE)/#if ! \1/;'
$ git grep -Ee 'if.*defined\(HAVE' -l|xargs sed -i -r 's/defined\((HAVE_[A-Z0-9_]*)\)/\1/g'
$ git grep -Ee 'if.*defined\(ENABLE' -l|xargs sed -i -r 's/defined\((ENABLE_[A-Z0-9_]*)\)/\1/g'
+ manual changes to meson.build

squash! build-sys: use #if Y instead of #ifdef Y everywhere

v2:
- fix incorrect setting of HAVE_LIBIDN2

Susant Sahani 593022fa37 systemd-link: add support to configure the device port (#6153)
This work allows to configure device port:

tp — An Ethernet interface using Twisted-Pair cable as the medium.
aui — Attachment Unit Interface (AUI). Normally used with hubs.
bnc — An Ethernet interface using BNC connectors and co-axial cable.
mii — An Ethernet interface using a Media Independent Interface (MII).
fibre — An Ethernet interface using Optical Fibre as the medium.

Lennart Poettering 1d84ad9445 util-lib: various improvements to kernel command line parsing
This improves kernel command line parsing in a number of ways:

a) An kernel option "foo_bar=xyz" is now considered equivalent to
   "foo-bar-xyz", i.e. when comparing kernel command line option names "-" and
   "_" are now considered equivalent (this only applies to the option names
   though, not the option values!). Most of our kernel options used "-" as word
   separator in kernel command line options so far, but some used "_". With
   this change, which was a source of confusion for users (well, at least of
   one user: myself, I just couldn't remember that it's systemd.debug-shell,
   not systemd.debug_shell). Considering both as equivalent is inspired how
   modern kernel module loading normalizes all kernel module names to use
   underscores now too.

b) All options previously using a dash for separating words in kernel command
   line options now use an underscore instead, in all documentation and in
   code. Since a) has been implemented this should not create any compatibility
   problems, but normalizes our documentation and our code.

c) All kernel command line options which take booleans (or are boolean-like)
   have been reworked so that "foobar" (without argument) is now equivalent to
   "foobar=1" (but not "foobar=0"), thus normalizing the handling of our
   boolean arguments. Specifically this means systemd.debug-shell and
   systemd_debug_shell=1 are now entirely equivalent.

d) All kernel command line options which take an argument, and where no
   argument is specified will now result in a log message. e.g. passing just
   "systemd.unit" will no result in a complain that it needs an argument. This
   is implemented in the proc_cmdline_missing_value() function.

e) There's now a call proc_cmdline_get_bool() similar to proc_cmdline_get_key()
   that parses booleans (following the logic explained in c).

f) The proc_cmdline_parse() call's boolean argument has been replaced by a new
   flags argument that takes a common set of bits with proc_cmdline_get_key().

g) All kernel command line APIs now begin with the same "proc_cmdline_" prefix.

h) There are now tests for much of this. Yay!

Martin Pitt dbe81cbd2a siphash24: change result argument to uint64_t
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.

Lennart Poettering 07630cea1f util-lib: split our string related calls from util.[ch] into its own file 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.

Jacob Keller 66d3752e81 document ability to disable MACAddressPolicy
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.

Tom Gundersen 7eb08da4b3 udev: net_setup - allow matching on OriginalName=
This has been requested repeatedly, so let's give it a go. We explicitly do not allow matching
on names that have already been changed (from a previous udev run, or otherwise), and matching
on unpredictable names (ethX) is discouraged (but not currently disallowed).

We also currently allow:

[Match]
Name=veth0

[Link]
Name=my-name0
SomeOtherSetting=true

Which means that the link file will be applied the first time it is invoked, but
not on subsequent invocations, which may be surprising.

Michal Schmidt 0a1beeb642 treewide: auto-convert the simple cases to log_*_errno()
As a followup to 086891e5c1 "log: add an "error" parameter to all
low-level logging calls and intrdouce log_error_errno() as log calls
that take error numbers", use sed to convert the simple cases to use
the new macros:

find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/'

Multi-line log_*() invocations are not covered.
And we also should add log_unit_*_errno().

Tom Gundersen 04b67d4925 udev: link_setup - respect kernel name assign policy
Newer kernels export meta-information about the origin of an ifname. Respect this
from the ifname rename logic. We do not rename any interfaces that was originally
named by userspace, nor once which have already been renamed from userspace.

Moreover, we optionally do not (the default) rename interfaces which the kernel
claims to have named in a predictable way.

Zbigniew Jędrzejewski-Szmek a2a5291b3f Reject invalid quoted strings
String which ended in an unfinished quote were accepted, potentially
with bad memory accesses.

Reject anything which ends in a unfished quote, or contains
non-whitespace characters right after the closing quote.

_FOREACH_WORD now returns the invalid character in *state. But this return
value is not checked anywhere yet.

Also, make 'word' and 'state' variables const pointers, and rename 'w'
to 'word' in various places. Things are easier to read if the same name
is used consistently.

mbiebl_> am I correct that something like this doesn't work
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"'
mbiebl_> systemd seems to strip of the quotes
mbiebl_> systemctl status shows
mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS  $RootDir $MountPoint
