This series addresses issues related to MLO handling in probe response acceptance and scan request validation. * Validate SCAN_FLAG_AP in scan request during MLO: Enforce the requirement for the NL80211_SCAN_FLAG_AP flag in scan requests when an AP interface is beaconing. Apply this restriction to ML interfaces by using the existing helper ieee80211_num_beaconing_links() to check if any link is beaconing. * Accept probe response on link address as well: Ensure unicast probe response frames are accepted if the destination address matches any of the link addresses when a random MAC address is not requested. This change corrects the behavior where probe response frames are dropped incorrectly for MLO interfaces. Both the changes are as such independent from each other. Since both are related to MLO scanning, currently kept in same series. --- Changes in v2: - Use ieee80211_num_beaconing_links() alone since now it can handle non-mlo as well. - Link to v1: https://lore.kernel.org/r/20250513-bug_fix_mlo_scan-v1-0-94235bb42fbe@xxxxxxxxxxxxxxxx --- Aditya Kumar Singh (2): wifi: mac80211: validate SCAN_FLAG_AP in scan request during MLO wifi: mac80211: accept probe response on link address as well net/mac80211/cfg.c | 2 +- net/mac80211/scan.c | 18 +++++++++++++++++- 2 files changed, 18 insertions(+), 2 deletions(-) --- base-commit: 68b44b05f4c880c42109a91d2e0e7faa94f40529 change-id: 20250402-bug_fix_mlo_scan-fe57f57b1c86
