apteryx pushed a commit to branch master
in repository guix.
commit 1bdeec5d66cfeea3a5fc5d69690dd32cb32ee104
Author: muradm <mail@muradm.net>
AuthorDate: Sun Dec 17 15:49:21 2023 +0300
services: connman: Add 'connman-general-configuration'.
Currently connman has no main.conf as specified in 'man 5 connman.conf'
which
would allow setting NetworkInterfaceBalcklist and other useful options.
This patch adds connman-general-configuration, serializes it and
passes to connmad with --config= flag.
All configuration fields are 'maybe-*' deliberately, to not disturb current
users and not require supporting configuration changes for connmand.
* gnu/services/networking.scm (<connman-general-configuration>): New
configuration record to represent main.conf for connmand.
(<connman-configuration>)[general-configuration]: New field.
(connman-shepherd-service): Honor it.
*doc/guix.texi (Networking Services): Add generated configuration.

+@table @asis
+@item @code{input-request-timeout} (type: maybe-number)
+Set input request timeout. Default is 120 seconds. The request for
+inputs like passphrase will timeout after certain amount of time. Use
+this setting to increase the value in case of different user interface
+designs.
+
+@item @code{browser-launch-timeout} (type: maybe-number)
+Set browser launch timeout. Default is 300 seconds. The request for
+launching a browser for portal pages will timeout after certain amount
+of time. Use this setting to increase the value in case of different
+user interface designs.
+
+@item @code{background-scanning?} (type: maybe-boolean)
+Enable background scanning. Default is true. If wifi is disconnected,
+the background scanning will follow a simple back off mechanism from 3s
+up to 5 minutes. Then, it will stay in 5 minutes unless user
+specifically asks for scanning through a D-Bus call. If so, the
+mechanism will start again from 3s. This feature activates also the
+background scanning while being connected, which is required for roaming
+on wifi. When @code{background-scanning?} is false, ConnMan will not
+perform any scan regardless of wifi is connected or not, unless it is
+requested by the user through a D-Bus call.
+
+@item @code{use-gateways-as-timeservers?} (type: maybe-boolean)
+Assume that service gateways also function as timeservers. Default is
+false.
+
+@item @code{fallback-timeservers} (type: maybe-list)
+List of Fallback timeservers. These timeservers are used for NTP sync
+when there are no timeservers set by the user or by the service, and
+when @code{use-gateways-as-timeservers?} is @code{#f}. These can
+contain a mixed combination of fully qualified domain names, IPv4 and
+IPv6 addresses.
+
+@item @code{fallback-nameservers} (type: maybe-list)
+List of fallback nameservers appended to the list of nameservers given
+by the service. The nameserver entries must be in numeric format, host
+names are ignored.
+
+@item @code{default-auto-connect-technologies} (type: maybe-list)
+List of technologies that are marked autoconnectable by default. The
+default value for this entry when empty is @code{"ethernet"},
+@code{"wifi"}, @code{"cellular"}. Services that are automatically
+connected must have been set up and saved to storage beforehand.
+
+@item @code{default-favourite-technologies} (type: maybe-list)
+List of technologies that are marked favorite by default. The default
+value for this entry when empty is @code{"ethernet"}. Connects to
+services from this technology even if not setup and saved to storage.
+
+@item @code{always-connected-technologies} (type: maybe-list)
+List of technologies which are always connected regardless of
+preferred-technologies setting (@code{auto-connect?} @code{#t}). The
+default value is empty and this feature is disabled unless explicitly
+enabled.
+
+@item @code{preferred-technologies} (type: maybe-list)
+List of preferred technologies from the most preferred one to the least
+preferred one. Services of the listed technology type will be tried one
+by one in the order given, until one of them gets connected or they are
+all tried. A service of a preferred technology type in state 'ready'
+will get the default route when compared to another preferred type
+further down the list with state 'ready' or with a non-preferred type; a
+service of a preferred technology type in state 'online' will get the
+default route when compared to either a non-preferred type or a
+preferred type further down in the list.
+
+@item @code{network-interface-blacklist} (type: maybe-list)
+List of blacklisted network interfaces. Found interfaces will be
+compared to the list and will not be handled by ConnMan, if their first
+characters match any of the list entries. Default value is
+@code{"vmnet"}, @code{"vboxnet"}, @code{"virbr"}, @code{"ifb"}.
+
+@item @code{allow-hostname-updates?} (type: maybe-boolean)
+Allow ConnMan to change the system hostname. This can happen for
+example if we receive DHCP hostname option. Default value is @code{#t}.
+
+@item @code{allow-domainname-updates?} (type: maybe-boolean)
+Allow connman to change the system domainname. This can happen for
+example if we receive DHCP domainname option. Default value is
+@code{#t}.
+
+@item @code{single-connected-technology?} (type: maybe-boolean)
+Keep only a single connected technology at any time. When a new service
+is connected by the user or a better one is found according to
+preferred-technologies, the new service is kept connected and all the
+other previously connected services are disconnected. With this setting
+it does not matter whether the previously connected services are in
+'online' or 'ready' states, the newly connected service is the only one
+that will be kept connected. A service connected by the user will be
+used until going out of network coverage. With this setting enabled
+applications will notice more network breaks than normal. Note this
+options can't be used with VPNs. Default value is @code{#f}.
+
+@item @code{tethering-technologies} (type: maybe-list)
+List of technologies that are allowed to enable tethering. The default
+value is @code{"wifi"}, @code{"bluetooth"}, @code{"gadget"}. Only those
+technologies listed here are used for tethering. If one wants to tether
+ethernet, then add @code{"ethernet"} in the list. Note that if ethernet
+tethering is enabled, then a DHCP server is started on all ethernet
+interfaces. Tethered ethernet should never be connected to corporate or
+home network as it will disrupt normal operation of these networks. Due
+to this ethernet is not tethered by default. Do not activate ethernet
+tethering unless you really know what you are doing.
+
+@item @code{persistent-tethering-mode?} (type: maybe-boolean)
+Restore earlier tethering status when returning from offline mode,
+re-enabling a technology, and after restarts and reboots. Default value
+is @code{#f}.
+
+@item @code{enable-6to4?} (type: maybe-boolean)
+Automatically enable anycast 6to4 if possible. This is not recommended,
+as the use of 6to4 will generally lead to a severe degradation of
+connection quality. See RFC6343. Default value is @code{#f} (as
+recommended by RFC6343 section 4.1).
+
+@item @code{vendor-class-id} (type: maybe-string)
+Set DHCP option 60 (Vendor Class ID) to the given string. This option
+can be used by DHCP servers to identify specific clients without having
+to rely on MAC address ranges, etc.
+
+@item @code{enable-online-check?} (type: maybe-boolean)
+Enable or disable use of HTTP GET as an online status check. When a
+service is in a READY state, and is selected as default, ConnMan will
+issue an HTTP GET request to verify that end-to-end connectivity is
+successful. Only then the service will be transitioned to ONLINE state.
+If this setting is false, the default service will remain in READY
+state. Default value is @code{#t}.
+
+@item @code{online-check-ipv4-url} (type: maybe-string)
+IPv4 URL used during the online status check. Please refer to the
+README for more detailed information. Default value is
+@uref{http://ipv4.connman.net/online/status.html}.
+
+@item @code{online-check-ipv6-url} (type: maybe-string)
+IPv6 URL used during the online status check. Please refer to the
+README for more detailed information. Default value is
+@uref{http://ipv6.connman.net/online/status.html}.
+
+@item @code{online-check-initial-interval} (type: maybe-number)
+Range of intervals between two online check requests. Please refer to
+the README for more detailed information. Default value is @samp{1}.
+
+@item @code{online-check-max-interval} (type: maybe-number)
+Range of intervals between two online check requests. Please refer to
+the README for more detailed information. Default value is @samp{1}.
+
+@item @code{enable-online-to-ready-transition?} (type: maybe-boolean)
+WARNING: This is an experimental feature. In addition to
+@code{enable-online-check} setting, enable or disable use of HTTP GET to
+detect the loss of end-to-end connectivity. If this setting is
+@code{#f}, when the default service transitions to ONLINE state, the
+HTTP GET request is no more called until next cycle, initiated by a
+transition of the default service to DISCONNECT state. If this setting
+is @code{#t}, the HTTP GET request keeps being called to guarantee that
+end-to-end connectivity is still successful. If not, the default
+service will transition to READY state, enabling another service to
+become the default one, in replacement. Default value is @code{#f}.
+
+@item @code{auto-connect-roaming-services?} (type: maybe-boolean)
+Automatically connect roaming services. This is not recommended unless
+you know you won't have any billing problem. Default value is
+@code{#f}.
+
+@item @code{address-conflict-detection?} (type: maybe-boolean)
+Enable or disable the implementation of IPv4 address conflict detection
+according to RFC5227. ConnMan will send probe ARP packets to see if an
+IPv4 address is already in use before assigning the address to an
+interface. If an address conflict occurs for a statically configured
+address, an IPv4LL address will be chosen instead (according to
+RFC3927). If an address conflict occurs for an address offered via
+DHCP, ConnMan sends a DHCP DECLINE once and for the second conflict
+resorts to finding an IPv4LL address. Default value is @code{#f}.
+
+@item @code{localtime} (type: maybe-string)
+Path to localtime file. Defaults to @file{/etc/localtime}.
+
+@item @code{regulatory-domain-follows-timezone?} (type: maybe-boolean)
+Enable regulatory domain to be changed along timezone changes. With
+this option set to true each time the timezone changes the first present
+ISO3166 country code is read from
+@file{/usr/share/zoneinfo/zone1970.tab} and set as regulatory domain
+value. Default value is @code{#f}.
+
+@item @code{resolv-conf} (type: maybe-string)
+Path to resolv.conf file. If the file does not exist, but intermediate
+directories exist, it will be created. If this option is not set, it
+tries to write into @file{/var/run/connman/resolv.conf} if it fails
+(@file{/var/run/connman} does not exist or is not writeable). If you do
+not want to update resolv.conf, you can set @file{/dev/null}.
