There are different types (variants) of UUIDs defined.
Especially variants 3 and 5 are name based variants (rfc4122).
The way we create our UUIDs in nm_utils_uuid_generate_from_string()
however does not create them according to RFC and does not set
the flags to indicate the variant.
Modify the signature of nm_utils_uuid_generate_from_string() to accept
a "uuid_type" argument, so that we later can add other algorithms without
breaking API.
In general, we shouldn't end up with an unencrypted copy of a
certificate key anyway, so this function ought to be unnecessary (or
at least, not broadly useful enough to be in the public API).
nm-applet's GConf migration tool needs it, but that will eventually go
away, and until then it can just use libnm-util.
crypto_md5_hash() only has two users:
(a) crypto_make_des_aes_key()
(b) nm_utils_uuid_generate_from_string()
For (b) it is just a complicated way to compute the MD5 hash. The
restrictions on salt and password don't matter. Actually they
are harmful because we cannot compute the MD5 hash of the empty
word.
For (a), the caller should make sure to pass whatever restrictions
he wants to enforce on the data.
For example, it is counterintuitive, that crypto_md5_hash() would
require @salt_len, enforce it to be at least 8 bytes, and then just
use the first 8 bytes. If the caller (a) wants that behavior, he
should make sure that he passes in 8 bytes.
Likewise for the empty word. If the caller does not want to compute
the hash of empty passwords, he must not hash them.
Indeed, all of this was enforced by assertions, any caller already
did the right thing.
Rather than requiring crypto_init() to have been called beforehand,
just have every method that depends on it call it itself.
This required adding a GError argument to crypto_is_pkcs12_data(),
which in turn required a few other changes elsewhere.
We were always using the gateway field of the first address in
ipv4.addresses / ipv6.addresses to set the gateway, but to be
compatible with old behavior, we should actually be using the first
non-0 gateway field (if the first one is 0).
NMIPRoute is used by NMSettingIPConfig, but also
NMIPConfig. In the former case, default routes are (still)
disallowed. But in the NMIPConfig use-case, it can make sense
to expose default routes as NMIPRoute instances.
Relax the restriction on the NMIPRoute API to allow this
future change.
No code actually supports having NMIPRoute instances with
prefix length zero (default routes). Up to now, all such uses
would be a bug.

Add nm-utils methods to check if a file is a certificate or private
key file.
nm-applet currently has its own internal versions of these, but they
ended up having to duplicate a bunch of logic that we already have in
crypto.c.
Update crypto_verify_private_key() and
crypto_verify_private_key_data() to indicate whether the key was
encrypted or not.
Rename crypto_decrypt_private_key() and
crypto_decrypt_private_key_data() to
crypto_decrypt_openssl_private_key*, since that's the only private key
format they deal with, and the old names made them sound more generic
than they were. Also, update the openssl private key parsing code to
recognize unencrypted private keys as well. (Previously we accepted
unencrypted PKCS#8 keys, but not unencrypted openssl-style keys.)

Since libnm-core secret-flags properties are now enum-typed rather
than just being uints, we can now actually recognize them when
generating docs, rather than just assuming that every property whose
name ends in '-flags', but isn't in NMSettingDcb, is a secret-flags
property.
Add "---dbus---" sections to the NMSetting property docs, in the same
style as the plugin docs, parse them out into a file
"nm-setting-docs-overrides.xml", and use them to override the GObject
property docs in nm-setting-docs.xml.
This lets us put more D-Bus-specific information in the setting docs,
without cluttering up the property docs, and it also lets us document
dbus-only properties.
Add nm_setting_get_dbus_property_type(), and use this to get the
correct type for properties in nm-seting-docs.xml, in situations where
the D-Bus and GObject property types don't match.
In the case of enum/flags-valued properties, give both the enum name
and the underlying D-Bus type.
Each GBytes-valued property was using
_nm_setting_class_transform_property() to register a GBytes<->'ay'
transform. So just build that rule into the generic machinery in
nm-setting.c.
Move the settings/plugins doc generation from libnm-util to
libnm-core, since libnm-util isn't being updated for all new
properties.
With this commit, the keyfile and ifcfg-rh documentation is basically
unchanged, except that deprecated properties are now gone, and new
properties have been added, and the sections are in a different order.
(generate-plugin-docs.pl just outputs the settings in Makefile order,
and they were unsorted in libnm-util, but are sorted in libnm-core).
The settings documentation used for nm-settings.5, the D-Bus API docs,
and the nmcli help is changed a bit more at this point, and mostly for
the worse, since the libnm-core setting properties don't match up with
the D-Bus API as well as the libnm-util ones do. To be fixed...
(I also removed the "plugins docs" line in each plugin docs comment
block while moving them, since those blocks will be used for more than
just plugins soon, and it's sort of obvious anyway.)
Although libnm filters out properties received from the daemon that it
doesn't understand, there may be other clients that do not. In
particular, a client might call GetSettings() on a connection, update
the ipv4.addresses property in the returned dictionary, and then pass
the dictionary to Update(). In that case, the updated dictionary would
contain ipv4.address-data, but it would not reflect the changes the
client intended to make.
Fix this by changing the daemon side to prefer the legacy properties
to the new ones if both are set, and changing the client side to not
send the legacy properties (since we don't support new clients talking
to old servers anyway).
All the old "const GByteArray" methods got changed to return a GBytes
instead, but since they aren't declared "const" any more, we need to
explicitly annotate them "(transfer none)".
Also, the scanner apparently doesn't recognize that an (out)
"const char **" is "(transfer none)", so annotate that in two places
too
Libraries need to include <gi18n-lib.h>, not <gi18n.h>, so that _()
will get defined to "dgettext (GETTEXT_DOMAIN, string)" rather than
"gettext (string)" (which will use the program's default domain, which
works fine for programs in the NetworkManager tree, but not for
external users). Likewise, we need to call bindtextdomain() so that
gettext can find the translations if the library is installed in a
different prefix from the program using it (and
bind_textdomain_codeset(), so it will know the translations are in
UTF-8 even if the locale isn't).
(The fact that no one noticed this was broken before is because the
libraries didn't really start returning useful translated strings much
until 0.9.10, and none of the out-of-tree clients have been updated to
actually show those strings to users yet.)
config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
Make the type return GBytes since most in-tree users want that.
Allow the function to accept many more formats as valid hex, including
bytes delimited by ':' and a leading '0x'.
Update the docs build to include and exclude the correct files.
Fill in some missing documentation, and fix problems in the existing
docs. (In particular, "<" can't appear as a literal in documentation,
so change it to "<". Also, "PKCS#12" has to be written as
"PKCS#<!-- -->12", or gtk-doc will think "#12" is a reference to a
type named "12".)
b64c82a3 removed the warning in libnm-util when
nm_setting_new_from_hash() sees an unrecognized property, but we were
still warning in the equivalent libnm-core code. But it doesn't make
sense to warn here either: we do add new properties sometimes, but we
always make sure that older clients still get the information they
need as well, so they can just ignore the new property.
Add AddressData and RouteData properties to NMSettingIPConfig and
NMIP[46]Config. These are like the existing "addresses" and "routes"
properties, but using strings and containing additional attributes,
like NMIPAddress and NMIPRoute.
This only affects the D-Bus representations; there are no API changes
to NMSettingIP{,4,6}Config or NMIP{4,6}Config as a result of this; the
additional information is just added to the existing 'addresses' and
'routes' properties.
NMSettingIP4Config and NMSettingIP6Config now always generate both
old-style data ('addresses', 'address-labels', 'routes') and new-style
data ('address-data', 'gateway', 'route-data') when serializing to
D-Bus, for backward compatibility. When deserializing, they will fill
in the 'addresses' and 'routes' properties from the new-style data if
it is present (ignoring the old-style data), or from the old-style
data if the new-style isn't present.
The daemon-side NMIP4Config and NMIP6Config always emit changes for
both 'Addresses'/'Routes' and 'AddressData'/'RouteData'. The
libnm-side classes initially listen for changes on both properties,
but start ignoring the 'Addresses' and 'Routes' properties once they
know the daemon is also providing 'AddressData' and 'RouteData'.
