This makes it possible to utilize agents in the "external UI" mode
instead of hardcoded handling of VPN secrets requests.
Ideally this would be turned into a library so that nm-applet can share
the code, but figuring out the right API might be a non-trivial
undertaking.
We commonly don't use the glib typedefs for char/short/int/long,
but their C types directly.
$ git grep '\<g\(char\|short\|int\|long\|float\|double\)\>' | wc -l
587
$ git grep '\<\(char\|short\|int\|long\|float\|double\)\>' | wc -l
21114
One could argue that using the glib typedefs is preferable in
public API (of our glib based libnm library) or where it clearly
is related to glib, like during
g_object_set (obj, PROPERTY, (gint) value, NULL);
However, that argument does not seem strong, because in practice we don't
follow that argument today, and seldomly use the glib typedefs.
Also, the style guide for this would be hard to formalize, because
"using them where clearly related to a glib" is a very loose suggestion.
Also note that glib typedefs will always just be typedefs of the
underlying C types. There is no danger of glib changing the meaning
of these typedefs (because that would be a major API break of glib).
A simple style guide is instead: don't use these typedefs.
No manual actions, I only ran the bash script:
FILES=($(git ls-files '*.[hc]'))
sed -i \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\>\( [^ ]\)/\1\2/g' \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\> /\1 /g' \
-e 's/\<g\(char\|short\|int\|long\|float\|double\)\>/\1/g' \
"${FILES[@]}"
If the hints parameter to the agent request wasn't empty, ask
specifically for the 802-1x keys listed in the hints and skip the
guessing. I didn't add human readable names for all of the 802-1x
settings, it could be useful to do for at least the three 802-1x
properties that add_8021x_secrets already knows about because
those may have translations.

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.
Replace the usage of g_str_hash() with our own nm_str_hash().
GLib's g_str_hash() uses djb2 hashing function, just like we
do at the moment. The only difference is, that we use a diffrent
seed value.
Note, that we initialize the hash seed with random data (by calling
getrandom() or reading /dev/urandom). That is a change compared to
before.
This change of the hashing function and accessing the random pool
might be undesired for libnm/libnm-core. Hence, the change is not
done there as it possibly changes behavior for public API. Maybe
we should do that later though.
At this point, there isn't much of a change. This patch becomes
interesting, if we decide to use a different hashing algorithm.
Branch f9b1bc16e9 added bluetooth NAP
support. A NAP connection is of connection.type "bluetooth", but it
also has a "bridge" setting. Also, it is primarily handled by NMDeviceBridge
and NMBridgeDeviceFactory (with help from NMBluezManager).
However, don't let nm_connection_get_connection_type() and
nm_connnection_is_type() lie about what the connection.type is.
The type is "bluetooth" for most purposes -- at least, as far as
the client is concerned (and the public API of libnm). This restores
previous API behavior, where nm_connection_get_connection_type()
and nm_connection_is_type() would be simple accessors to the
"connection.type" property.
Only a few places care about the bridge aspect, and those places need special
treatment. For example NMDeviceBridge needs to be fully aware that it can
handle bluetooth NAP connection. That is nothing new: if you handle a
connection of any type, you must know which fields matter and what they
mean. It's not enough that nm_connection_get_connection_type() for bluetooth
NAP connectins is claiming to be a bridge.
Counter examples, where the original behavior is right:
src/nm-manager.c- g_set_error (error,
src/nm-manager.c- NM_MANAGER_ERROR,
src/nm-manager.c- NM_MANAGER_ERROR_FAILED,
src/nm-manager.c- "NetworkManager plugin for '%s' unavailable",
src/nm-manager.c: nm_connection_get_connection_type (connection));
the correct message is: "no bluetooth plugin available", not "bridge".
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: if ( ( nm_connection_is_type (connection, NM_SETTING_WIRED_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: && !nm_connection_get_setting_pppoe (connection))
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_VLAN_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_WIRELESS_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_INFINIBAND_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_BOND_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_TEAM_SETTING_NAME)
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c: || nm_connection_is_type (connection, NM_SETTING_BRIDGE_SETTING_NAME))
src/settings/plugins/ifcfg-rh/nms-ifcfg-rh-writer.c- return TRUE;
the correct behavior is for ifcfg-rh plugin to reject bluetooth NAP
connections, not proceed and store it.
Since we use g_str_has_prefix() to match a request_id with the
connection path, there can be wrong matches. For example:
request_id: /org/freedesktop/NetworkManager/Settings/10/802-1x
connection: /org/freedesktop/NetworkManager/Settings/1
would match. Add a trailing slash to the connection path stored in the
agent to prevent this.
- All internal source files (except "examples", which are not internal)
should include "config.h" first. As also all internal source
files should include "nm-default.h", let "config.h" be included
by "nm-default.h" and include "nm-default.h" as first in every
source file.
We already wanted to include "nm-default.h" before other headers
because it might contains some fixes (like "nm-glib.h" compatibility)
that is required first.
- After including "nm-default.h", we optinally allow for including the
corresponding header file for the source file at hand. The idea
is to ensure that each header file is self contained.
- Don't include "config.h" or "nm-default.h" in any header file
(except "nm-sd-adapt.h"). Public headers anyway must not include
these headers, and internal headers are never included after
"nm-default.h", as of the first previous point.
- Include all internal headers with quotes instead of angle brackets.
In practice it doesn't matter, because in our public headers we must
include other headers with angle brackets. As we use our public
headers also to compile our interal source files, effectively the
result must be the same. Still do it for consistency.
- Except for <config.h> itself. Include it with angle brackets as suggested by
https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers
The localization headers are now included via "nm-default.h".
Also fixes several places, where we wrongly included <glib/gi18n-lib.h>
instead of <glib/gi18n.h>. For example under "clients/" directory.
set_connection_path() is almost always called right before enable(),
and it's unclear why it would be called anywhere else. So just
merge the two methods.
nm_secret_agent_simple_*() functions should take an
NMSecretAgentSimple, not an NMSecretAgent.
The type macros were incorrectly validating against
NM_TYPE_SECRET_AGENT rather than NM_TYPE_SECRET_AGENT_SIMPLE.
If we're activating the device without knowing the connection in advance, defer
servicing the requests for the secrets until we set the path.
[lkundrak@fedora20-2 ~]$ nmcli --ask c ifname wlan0
(process:18405): libnm-CRITICAL **: nm_object_get_path: assertion 'NM_IS_OBJECT (object)' failed
Error: Connection activation failed: The device has no connections available.
[lkundrak@fedora20-2 ~]$
When a connection is being activated, nmcli could ask for secrets for another
connection, which might confuse users. We check the request now and only ask
for secrets of connection being activated.
Test case:
$ nmcli con up my-ethernet0
Passwords or encryption keys are required to access the wireless network 'Red Hat'.
Warning: password for '802-1x.identity' not given in 'passwd-file' and nmcli cannot ask without '--ask' option.
