* mac80211: add support for wds_bridge hostapd featureDaniel Golle2020-01-221-2/+6
| | | | | | | | | | | | | hostapd allows putting WDS (4addr mode) clients into a separate bridge other than the bridge regular (3addr mode) clients end up in. This is useful for example giving WDS clients access to several VLANs (trunking) while regular clients will end up inside a specific VLAN. Add 'wds_bridge' config parameter for wifi-iface which contains the name of the bridge. hostapd-mini already supports this feature, so all needed is to add the UCI wrapping in mac80211.sh.

* mac80211: fix txpower when using DFS channelsDavid Bauer2019-12-161-2/+7
| | | | | | | | | | | With this patch, txpower for the PHY is applied when configuring the PHY instead of the VIF. Otherwise, the configured txpower is not applied for the first initialized VIF when using DFS channels, as it is currently applied too early when the CAC hasn't finished.

* mac80211: don't call md5sum on non-existing fileDaniel Golle2019-12-081-1/+1
| | | | | | | | | | | | If no AP is configured, hostapd-${phy}.conf is not being created, hence md5sum fails and causes log pollution: netifd: radio1 (3183): md5sum: can't open '/var/run/hostapd-phy1.conf': No such file or directoy Hence make sure the file exists when calling md5sum.

* hostapd: re-introduce process trackingDaniel Golle2019-12-081-0/+3
| | | | | | | | | | | Before commit 60fb4c92b6 ("hostapd: add ubus reload") netifd was tracking hostapd/wpa_supplicant and restarting wifi in case of a process crash. Restore this behaviour by tracking the PIDs of hostapd and wpa_supplicant. Also make sure hostapd and/or wpa_supplicant have been started before emmitting ubus calls to them using ubus wait_for.

* mac80211: detect existing interface before addingDaniel Golle2019-11-161-4/+35
| | | | | | | | | | | | | | | Keep existing wdev when creating new nl80211 interfaces if phy and type match, delete it otherwise. To make this work, also remove left-over debugging function which prevented the return-value of the 'iw' command to be taken into account in mac80211_iw_interface_add(). As 4addr-mode (WDS) was setup during interface creation for station interfaces, also set it after interface creation to make sure an existing sta interface ends up with the right mode.

| | | | | | | | | | | | The channel can be selected automatically at run time by setting channel=acs_survey or channel=0, both of which will enable the ACS survey based algorithm in hostapd. If the option acs_exclude_dfs is set in the hostpad config DFS channels from ACS are excluded on channel selection. This commit will add the possibilty to exclude the dfs channel on ACS survey.

* mac80211: gracefully handle preexisting VIFJo-Philipp Wich2017-05-141-0/+6
| | | | | | | | | | | | | | | | | | | | Gracefully handle cases where the to-be-created wireless interface already exists on the system which might commonly happen with non-multi-SSID capable wireless drivers. This fixes commit 8301e613655c2d95fa5430a1a57d92d966fdc70b which caused previously ignored "Too many open files in system (-23)" errors to fail the wireless setup procedure. With the updated approach we'll still try recreating the vif after one second if the first attempt to do so failed with ENFILE but we will now consider the operation successfull if a second attempt still yields ENFILE with the requested ifname already existing on the system.

* mac80211, hostapd: always explicitly set beacon intervalMatthias Schiffer2017-05-131-4/+6
| | | | | | | | | | | | | | | | One of the latest mac80211 updates added sanity checks, requiring the beacon intervals of all VIFs of the same radio to match. This often broke AP+11s setups, as these modes use different default intervals, at least in some configurations (observed on ath9k). Instead of relying on driver or hostapd defaults, change the scripts to always explicitly set the beacon interval, defaulting to 100. This also applies the beacon interval to 11s interfaces, which had been forgotten before. VIF-specific beacon_int setting is removed from hostapd.sh. Fixes FS#619.

* mac80211: Fix race condition leading to wifi interfaces not coming up at ↵Vittorio Gambaletta2017-03-221-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boot sometimes. In the drv_mac80211_setup function, mac80211_interface_cleanup is called to ask the kernel to delete all existing interfaces for the phy that is being configured via netlink. Later in the first function, mac80211_prepare_vif is called to set up the new interfaces as required. But sometimes, when mac80211_prepare_vif (and so the relevant `iw phy x interface add y` command) runs, the kernel might still be cleaning up the old interface with the same ifname. It usually takes very few time to do that; possibly a few milliseconds of sleep in the script after detecting this error condition could be enough, but the busybox sh does not support sub-second sleep intervals. When this happens, iw obviously fails to create the new interface; and the following message is printed in the system log, followed by subsequent failure messages from hostapd in case this would have been an AP interface. Tue Mar 14 04:21:57 2017 daemon.notice netifd: radio1 (2767): command failed: Too many open files in system (-23) This was a long-standing issue existing since at least OpenWrt Backfire, and today I finally managed to debug and (hopefully) solve it. It was happening very few times on most devices; but it was happening a lot more frequently on fast platforms with multiple radios, such as the powerpc-based dual-ath9k-radio tl-wdr4900-v1.

* base-files, mac80211, broadcom-wl: use uci to populate wireless configChristian Lamparter2016-11-031-22/+21
| | | | | | | | | | | | | | | | | | | | Previously, wifi detect simply dumped its generated wireless configuration to STDOUT. A second step was needed to append the configuration to /etc/config/wireless (or create it, if it didn't exist). With this patch, The wifi detection script will now use uci to update the wireless configuration directly. This patch also makes the initially created wifi-iface a named section ('default_radio$X' for mac80211 and 'default_wl$X' for broadcom). With this change, uci will not print the cfgHASH to STDOUT (which would now corrupt the wireless configuration). It will also prevent adding duplicated wifi interface configurations, if the wifi configuration is run concurrently. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
