nm_utils_hwaddr_valid() is used for validating strings. It should
not assert against calling it with an empty string "". That is just
an invalid hwaddr.

Thanks to the marvelous effort of the GNU compiler developer we can now
spare a couple of bits that could be used for more important things,
like this commit message. Standards commitees yet have to catch up.
"nm-utils/nm-jansson.h" and thus <jansson.h> must be included only
after "nm-json.h". Enforce that by never including them directly,
except from "nm-json.h" itself.
Having it in libnm doesn't make any sense and prevents using it for more
internal functionality.
Too bad nm_utils_wifi_strength_bars() is already a public API.
No problem -- replace it with a compatible yet dumber equivalent.
binary-search can find an index of a matching entry in a sorted
list. However, if the list contains multiple entries that compare
equal, it can be interesting to find the first/last entry. For example,
if you want to append new items after the last.
Extend binary search to optionally continue the binary search
to determine the range that compares equal.
"no_value" indicates that the the attribute is a single word, not a
key=value pair. If the type is BOOLEAN then the attribute is considered
true, if it's a STRING then the key is used instead of a value.
"consumes_rest" indicates that the particular key takes the unparseable
tail of the string for a value.
This allows parsing tc-style strings. Consider this filter:
,------ regular key/value pair
,-----'----.
root handle 1234: matchall action simple foo bar baz
| | `-----------.-----------'
| | `- "", STRING, consumes_rest
| `------------------- "kind", STRING, no_value
`-------------------------------------- "root', BOOLEAN, no_value
Make use of NMUtilsNamedValue in nm_utils_format_variant_attributes().
This avoids creating a GList and sorting it.
Also, reuse nm_utils_named_values_from_str_dict() in
nm_setting_bond_get_option().
I don't think we should do this.
- renamining/dropping configure options is still an annoyance,
because it requires to different ./configure options depending
on the version. The rename from --enable-teamctl to --enable-team
might be theoretically nice, but more annoying then helpful.
- There is no strict dependency between --enable-team and
--enable-json-validation. At most, one could argue that
when enabling the team plugin (--enable-teamctl), then
libnm must also be build with --enable-json-validation.
But in fact, the team plugin will happily work with a
libnm that doesn't link against libjansson.
That is --enable-teamctl --disable-json-validation will work
in practice just fine.
On the other hand, libnm is a client library to create connection
profiles, fully supporting team profiles also makes sense if the
actual plugin is not installed (or build). Thus, --disable-teamctl
--enable-json-validation certainly makes sense.
At this point, one might ask whether libnm is even still complete without
libjansson. Maybe libnm should *require* --enable-json-validation.
But that is not what the patch was doing, and it would also need
some careful consideration before doing so.
This reverts commit 9d5cd7eae8.
Rename the team functionality enablement from 'teamdctl' to 'team'.
Force jansson lib requirement for team functionality: NetworkManager
requires the teamd daemon to manage team. As teamd depends upon jansson
lib, adding jansson requirement for teaming support in NetworkManager
seems reasonable.
Remove the jansson_validation flag, as the only generic json function in
nmcli (not related to team) was the one to check if a string was in json
format. Anyway, that function is used for team checks only. So, move
also json validation functions under the WITH_TEAM flag.
till now when no explicit value was set on a property, the default value
for that property was returned, also if the property was not applicable
to the selected runner.
Fix this, showing default values for properties only when relevant and
showing instead -1 or null when the property is not relevant for the
selected runner.
Moreover, reset all the properties but the link-watchers when the team.runner
is changed: this is required to clean up the properties unrelated to the
new runner and start with the runner-specific defaults.
Move code from _nm_utils_team_config_get to the brand new
_json_team_add_defaults function without any change.
Then remove the duplicated code from _nm_utils_team_config_equal and
leverage the new function. Here the only functional change is that
the defaults for "notify_peers" and "mcast_rejoin" for the
"activebackup" runner are added (the only case in which their default
values are different than 0).
When jansson lib version is < 2.8 the order of the keys of json objects
is not preserved automatically. In particular, when loading the json
string, parsing it and dumping it back to a string the key order will be
lost if the now deprecated JSON_PRESERVE_ORDER flag is not set.
Add the flag: will do nothing on recent jansson versions but will fix
behavior for legacy ones.
We should use the same str2bool parser everywhere: _nm_utils_ascii_str_to_bool().
Incidentally, this function allows more forms of expressing a boolean
value.
$ nmcli connection modify "$CON" ipv4.routes '1.2.3.4/32 1.2.3.1 onlink=1'
Error: failed to modify ipv4.routes: invalid option 'onlink=1': invalid boolean value '1' for attribute 'onlink'.
We also do this for libnm and libnm-core, where it causes visible changes
in behavior. But if somebody would rely on the hashing implementation
for hash tables, it would be seriously flawed.
Next we will use siphash24() instead of the glib version g_direct_hash() or
g_str_hash(). Hence, the "nm-utils/nm-hash-utils.h" header becomes very
fundamental and will be needed basically everywhere.
Instead of requiring the users to include them, let it be included via
"nm-default.h" header.
Currently there are multiple features that require Jansson support,
but WITH_JANSSON=1 is set only when configuring with
--enable-json-validation. Therefore a build with
"--disable-json-validation --enable-ovs" fails.
The availability of Jansson (WITH_JANSSON) should only be used:
- to check if dependent features can be enabled
- to determine compiler and linker flags in the Makefile
- in nm-jansson.h to define compatibility functions if needed
Everything else must be controlled by a configure switch.

We want to support large number of routes. Reduce the number
of copies, by adding internal accessor functions.
Also, work around a complaint from coverity:
46. NetworkManager-1.9.2/libnm-core/nm-utils.c:1987:
dereference: Dereferencing a null pointer "names".
Since kernel commit a4176a9391868bfa87705bcd2e3b49e9b9dd2996 (net:
reject creation of netdev names with colons), kernel rejects any
colons in the interface name.
Since kernel could get away with tightening up the check, we can
too.
The user anyway can not choose arbitrary interface names, like
"all", "default", "bonding_masters" are all going to fail one
way or another.
