| * cfg80211: call cfg80211_stop_ap when switch from P2P_GO typeNguyen Dinh Phi2021-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 563fbefed46ae4c1f70cffb8eb54c02df480b2c2 upstream. If the userspace tools switch from NL80211_IFTYPE_P2P_GO to NL80211_IFTYPE_ADHOC via send_msg(NL80211_CMD_SET_INTERFACE), it does not call the cleanup cfg80211_stop_ap(), this leads to the initialization of in-use data. For example, this path re-init the sdata->assigned_chanctx_list while it is still an element of assigned_vifs list, and makes that linked list corrupt.

This leads to initialization of in-use memory (e.g. init u.ibss while in-use by u.ocb) due to a shared struct/union within ieee80211_sub_if_data: struct ieee80211_sub_if_data { ... union { struct ieee80211_if_ap ap; struct ieee80211_if_vlan vlan; struct ieee80211_if_managed mgd; struct ieee80211_if_ibss ibss; // <- shares address struct ieee80211_if_mesh mesh; struct ieee80211_if_ocb ocb; // <- shares address struct ieee80211_if_mntr mntr; struct ieee80211_if_nan nan; } u; ... } Therefore add handling of otype == NL80211_IFTYPE_OCB, during cfg80211_change_iface() to perform cleanup when leaving OCB mode. link to syzkaller bug: https://syzkaller.appspot.com/bug?id=0612dbfa595bf4b9b680ff7b4948257b8e3732d5 Reported-by: syzbot+105896fac213f26056f9@syzkaller.appspotmail.com Signed-off-by: Du Cheng <ducheng2@gmail.com> Link: https://lore.kernel.org/r/20210428063941.105161-1-ducheng2@gmail.com Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
| * cfg80211: mitigate A-MSDU aggregation attacksMathy Vanhoef2021-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2b8a1fee3488c602aca8bea004a087e60806a5cf upstream. Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP) header, and if so dropping the complete A-MSDU frame. This mitigates known attacks, although new (unknown) aggregation-based attacks may remain possible. This defense works because in A-MSDU aggregation injection attacks, a normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042 header. In other words, the destination MAC address of the first A-MSDU subframe contains the start of an RFC1042 header during an aggregation attack. We can detect this and thereby prevent this specific attack. For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and Fragmentation". Note that for kernel 4.9 and above this patch depends on "mac80211: properly handle A-MSDUs that start with a rfc1042 header". Otherwise this patch has no impact and attacks will remain possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit a1d5ff5651ea592c67054233b14b30bf4452999c upstream. Properly parse A-MSDUs whose first 6 bytes happen to equal a rfc1042 header. This can occur in practice when the destination MAC address equals AA:AA:03:00:00:00. More importantly, this simplifies the next patch to mitigate A-MSDU injection attacks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it.

| * cfg80211: Purge frame registrations on iftype changeDenis Kenzior2019-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c1d3ad84eae35414b6b334790048406bd6301b12 upstream. Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird situations where frames possibly not allowed on a given interface type remain registered due to the type switching happening after registration. The kernel currently relies on userspace apps to actually purge the registrations themselves, this is not something that the kernel should rely on. Add a call to cfg80211_mlme_purge_registrations() to forcefully remove any registrations left over prior to switching the iftype.

I noticed this bug because in commit 9cf0a0b4b64a ("cfg80211: Add support for 60GHz band channels 5 and 6") we made "freq <= 56160 + 2160 * 6" a valid requency when before it was only "freq <= 56160 + 2160 * 4" that was valid. It introduces a static checker warning: net/wireless/util.c:1571 ieee80211_chandef_to_operating_class() warn: always true condition '(freq <= 56160 + 2160 * 6) => (0-u16max <= 69120)' But really we probably shouldn't have been truncating the high bits away to begin with.

This value will be compared against GCD of all beaconing interfaces of matching combinations. If the driver doesn't advertise this value, the old behaviour where all beacon intervals must be identical is retained. If it is specified, then any beacon interval for an interface in the interface combination as well as the GCD of all active beacon intervals in the combination must be greater or equal to this value.

* | cfg80211: Add option to report the bss entry in connect resultKanchanapally, Vidyullatha2016-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since cfg80211 maintains separate BSS table entries for APs if the same BSSID, SSID pair is seen on multiple channels, it is possible that it can map the current_bss to a BSS entry on the wrong channel. This current_bss will not get flushed unless disconnected and cfg80211 reports a wrong channel as the associated channel. Fix this by introducing a new cfg80211_connect_bss() function which is similar to cfg80211_connect_result(), but it includes an additional parameter: the bss the STA is connected to. This allows drivers to provide the exact bss entry that matches the BSS to which the connection was completed.

The new function is used by commit "cfg80211/mac80211: disconnect on suspend" which is reverted in order to avoid the disconnection while going to suspend.

* cfg80211: ignore netif running state when changing iftypeMichal Kazior2015-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was possible for mac80211 to be coerced into an unexpected flow causing sdata union to become corrupted. Station pointer was put into sdata->u.vlan.sta memory location while it was really master AP's sdata->u.ap.next_beacon. This led to station entry being later freed as next_beacon before __sta_info_flush() in ieee80211_stop_ap() and a subsequent invalid pointer dereference crash. The problem was that ieee80211_ptr->use_4addr wasn't cleared on interface type changes. This could be reproduced with the following steps: # host A and host B have just booted; no # wpa_s/hostapd running; all vifs are down host A> iw wlan0 set type station host A> iw wlan0 set 4addr on host A> printf 'interface=wlan0\nssid=4addrcrash\nchannel=1\nwds_sta=1' > /tmp/hconf host A> hostapd -B /tmp/conf host B> iw wlan0 set 4addr on host B> ifconfig wlan0 up host B> iw wlan0 connect -w hostAssid host A> pkill hostapd # host A crashed: [ 127.928192] BUG: unable to handle kernel NULL pointer dereference at 00000000000006c8 [ 127.929014] IP: [<ffffffff816f4f32>] __sta_info_flush+0xac/0x158 ...

* cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnectJohannes Berg2015-05-26
| | | | | | | | | | | | | | | | | | | | When we disconnect from the AP, drivers call cfg80211_disconnect(). This doesn't know whether the disconnection was initiated locally or by the AP though, which can cause problems with the supplicant, for example with WPS. This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

Change this to no longer be flags but use a separate field for the bandwidth ('bw') instead. While at it, add support for 5 and 10 MHz rates - these are reported as regular legacy rates with their real bitrate, but tagged as 5/10 now to make it easier to distinguish them. In the nl80211 API, the flags are preserved, but the code now can also clearly only set a single one of the flags. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
