* mac80211: allow ACS restriction with fixed channelJan Hoffmann2020-07-061-1/+1
| | | | | | | | | | | This can be useful when a DFS channel is configured, as the ACS channel list is taken into account when switching channels after a radar event. For example, this allows to prevent the SRD channels from being used in that case. Signed-off-by: Jan Hoffmann <jan@3e8.eu> [reorder structure] Signed-off-by: David Bauer <mail@david-bauer.net>
* mac80211: fix use of local variableLeon M. George2020-06-241-1/+1
| | | | | | | | | | mac80211_get_addr is called from mac80211_generate_mac, where the local variable initialisation id="${macidx:-0}" suggests that macidx is not always defined. Probably, idx was supposed to be used instead of $(($macidx + 1)).

* mac80211: make sure existing iface belongs to correct (fullmac) phyDaniel Golle2020-04-171-8/+18
| | | | | | | | | | | | | | Some FullMAC cfg80211 wireless devices do not support virtual interfaces, hence there is script logic to keep the existing network device. Improve this to support renaming the interface if needed and make sure the existing interface actually belongs to the right phy. Change calls to 'iw' to avoid outputing warnings and errors to not confuse users of such devices. Also bump PKG_RELEASE which has been forgotten in the previous two mac80211 changes.

* mac80211: do not try to setup hostapd-managed interfaces.Oldřich Jedlička2020-03-201-7/+11
| | | | | | | | | | | | | | | | | | | | | | For virtual access points (when multiple SSIDs are used for one physical AP), there exist one physical network interface and multiple virtual interfaces, which are fully under control of hostapd. When networking is setup, the script `/lib/netifd/wireless/mac80211.sh` is called, which tries to bring the interface up by a call to `ip link set dev <iface> up`. This call might fail for virtual APs, because the virtual interface might not have been created by hostapd yet. There are some artifical delays in the script most probably to handle this, but when DFS channel availability check on 5GHz band is issued, hostapd can delay creating virtual interfaces by a minute. In order to fix this (or work around it), do not try to bring the interface up (this is responsibility of hostapd anyway) and do not try to set txpower on the virtual interface. Fixes FS#2698.

* 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.

| | | | | | | | | | | Before commit 60fb4c92b6 ("hostapd: add ubus reload") netifd was tracking hostapd/wpa_supplicant and restarting wifi in case of a process crash.

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.

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.
