wifi: mac80211_hwsim: claim DBE capability

2026-06-03T12:11:59+00:00

Claim DBE capability in UHR MAC capabilities, hostapd will have to sort out the actual DBE capabilities based on the EHT capabilities. Link: https://patch.msgid.link/20260529102644.4db84674e8c2.I8731be8ea589c94ece5623e7e716cbbc03f50466@changeid Signed-off-by: Johannes Berg

wifi: Update UHR PHY capabilities to D1.4

2026-06-03T12:11:58+00:00

There are new capabilities in D1.4, and some reserved bits. Update the code accordingly. Link: https://patch.msgid.link/20260529102644.f146932b21e2.I12bad84157bf809fbe285b79420143b3c456d9d2@changeid Signed-off-by: Johannes Berg

wifi: cfg80211: remove 5/10 MHz channel support

2026-06-03T12:07:05+00:00

Remove WIPHY_FLAG_SUPPORTS_5_10_MHZ and 5/10 MHz channel width support. We contemplated this back in early 2023 and didn't do it yet, but nobody stepped up to maintain it. It's already _mostly_ dead code since it can really only be used for AP and maybe IBSS and monitor, but not on a client since there's no way to scan (and hasn't been in a very long time, if ever), so the only thing that ever could really happen with it was run syzbot and trip over assumptions in the code.

wifi: mac80211_hwsim: add debug messages for link changes

2026-05-28T07:50:06+00:00

It's useful to be able to see the link addresses when the interface links change, so add some prints to hwsim for the vif link change callback.

wifi: mac80211_hwsim: modernise S1G channel list

2026-05-28T07:48:15+00:00

The current S1G channel list in mac80211_hwsim does not represent what S1G drivers would advertise that being 1MHz primaries. Also, include the NO_PRIMARY flag on the edgeband 1MHz primaries to emulate US operation such that it can also be tested.

wifi: mac80211_hwsim: don't run RC update on new STA on S1G vif

2026-05-28T07:48:15+00:00

mac80211_hwsim_sta_rc_update() is unable to handle S1G widths so when a new STA is added under a S1G vif the WARN is hit preventing hwsim use for S1G. For now, skip calling rc_update() for S1G interfaces. This is required such that the soon-to-be S1G hwsim tests can successfully run.

Do not declare support for Extended Key ID for NAN, as defined in section 7.4 in the WiFi Aware specification v4.0 (in order to support security association upgrade).

wifi: mac80211_hwsim: reject NAN on multi-radio wiphys

2026-05-20T10:02:10+00:00

When userspace creates a new hwsim radio with both HWSIM_ATTR_MULTI_RADIO and HWSIM_ATTR_SUPPORT_NAN_DEVICE, hwsim_new_radio_nl() sets BIT(NL80211_IFTYPE_NAN_DATA) in wiphy->interface_modes while configuring the wiphy with n_radio > 1. This violates the invariant checked in wiphy_register(): (interface_modes & BIT(NL80211_IFTYPE_NAN_DATA)) && (!nan_capa.phy.ht.ht_supported || n_radio > 1) triggering a WARN reachable from userspace via genetlink. With panic_on_warn this becomes a denial of service. Refuse the combination at parse time with -EINVAL and an extack message, matching the cfg80211 constraint that NAN is not supported on multi-radio wiphys.

2026-05-06T09:42:12+00:00

This is already claimed for VHT and HE, so it doesn't really make sense to not claim it for HT, and this causes sigma-dut failures since it assumes VHT support implies HT support. Link: https://patch.msgid.link/20260506093231.155762-2-johannes@sipsolutions.net Signed-off-by: Johannes Berg
