-Subject: [PATCH] mac80211: mesh: clean up rx_bcn_presp API
-
-commit a5b983c6073140b624f64e79fea6d33c3e4315a0 upstream.
-
-We currently pass the entire elements to the rx_bcn_presp()
-method, but only need mesh_config. Additionally, we use the
-length of the elements to calculate back the entire frame's
-length, but that's confusing - just pass the length of the
-frame instead.

-
-commit 49a765d6785e99157ff5091cc37485732496864e upstream.
-
-There's no need to parse all elements etc. just to find the
-authentication challenge - use cfg80211_find_elem() instead.
-This also allows us to remove WLAN_EID_CHALLENGE handling
-from the element parsing entirely.

-Subject: [PATCH] mac80211: always allocate struct ieee802_11_elems
-
-As the 802.11 spec evolves, we need to parse more and more
-elements. This is causing the struct to grow, and we can no
-longer get away with putting it on the stack.
-
-Change the API to always dynamically allocate and return an
-allocated pointer that must be kfree()d later.
-
-As an alternative, I contemplated a scheme whereby we'd say
-in the code which elements we needed, e.g.
-
-    DECLARE_ELEMENT_PARSER(elems,
-                           SUPPORTED_CHANNELS,
-                           CHANNEL_SWITCH,
-                           EXT(KEY_DELIVERY));
-
-    ieee802_11_parse_elems(..., &elems, ...);
-
-and while I think this is possible and will save us a lot
-since most individual places only care about a small subset
-of the elements, it ended up being a bit more work since a
-lot of places do the parsing and then pass the struct to
-other functions, sometimes with multiple levels.

-Subject: [PATCH] mac80211: fix memory leaks with element parsing
-
-commit 8223ac199a3849257e86ec27865dc63f034b1cf1 upstream.
-
-My previous commit 5d24828d05f3 ("mac80211: always allocate
-struct ieee802_11_elems") had a few bugs and leaked the new
-allocated struct in a few error cases, fix that.
-
-Fixes: 5d24828d05f3 ("mac80211: always allocate struct ieee802_11_elems")
-Signed-off-by: Johannes Berg <johannes.berg at intel.com>

-Subject: [PATCH] wifi: cfg80211: fix u8 overflow in
- cfg80211_update_notlisted_nontrans()
-
-commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.
-
-In the copy code of the elements, we do the following calculation
-to reach the end of the MBSSID element:
-
-	/* copy the IEs after MBSSID */
-	cpy_len = mbssid[1] + 2;
-
-This looks fine, however, cpy_len is a u8, the same as mbssid[1],
-so the addition of two can overflow. In this case the subsequent
-memcpy() will overflow the allocated buffer, since it copies 256
-bytes too much due to the way the allocation and memcpy() sizes
-are calculated.
-
-Fix this by using size_t for the cpy_len variable.
-
-This fixes CVE-2022-41674.

-
-commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream
-
-Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
-and the minimum is 1 since a multiple BSSID set with just one BSSID
-doesn't make sense (the # of BSSIDs is limited by 2^n).
-
-Limit this in the parsing in both cfg80211 and mac80211, rejecting
-any elements with an invalid value.
-
-This fixes potentially bad shifts in the processing of these inside
-the cfg80211_gen_new_bssid() function later.
-
-I found this during the investigation of CVE-2022-41674 fixed by the
-previous patch.

-
-commit ff05d4b45dd89b922578dac497dcabf57cf771c6
-
-When we parse a multi-BSSID element, we might point some
-element pointers into the allocated nontransmitted_profile.
-However, we free this before returning, causing UAF when the
-relevant pointers in the parsed elements are accessed.
-
-Fix this by not allocating the scratch buffer separately but
-as part of the returned structure instead, that way, there
-are no lifetime issues with it.
-
-The scratch buffer introduction as part of the returned data
-here is taken from MLO feature work done by Ilan.
-
-This fixes CVE-2022-42719.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.
-
-There are multiple refcounting bugs related to multi-BSSID:
- - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
-   the bss pointer is overwritten before checking for the
-   transmitted BSS, which is clearly wrong. Fix this by using
-   the bss_from_pub() macro.
-
- - In cfg80211_bss_update() we copy the transmitted_bss pointer
-   from tmp into new, but then if we release new, we'll unref
-   it erroneously. We already set the pointer and ref it, but
-   need to NULL it since it was copied from the tmp data.
-
- - In cfg80211_inform_single_bss_data(), if adding to the non-
-   transmitted list fails, we unlink the BSS and yet still we
-   return it, but this results in returning an entry without
-   a reference. We shouldn't return it anyway if it was broken
-   enough to not get added there.
-
-This fixes CVE-2022-42720.

-If a non-transmitted BSS shares enough information (both

-Since this is an erroneous situation, simply fail the

-BSS.

- P2P-device
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit b2d03cabe2b2e150ff5a381731ea0355459be09f upstream.
-
-If beacon protection is active but the beacon cannot be
-decrypted or is otherwise malformed, we call the cfg80211
-API to report this to userspace, but that uses a netdev
-pointer, which isn't present for P2P-Device. Fix this to
-call it only conditionally to ensure cfg80211 won't crash
-in the case of P2P-Device.
-
-This fixes CVE-2022-42722.

-Reported-by: Sönke Huster <shuster at seemoo.tu-darmstadt.de>
-Fixes: 9eaf183af741 ("mac80211: Report beacon protection failures to user space")

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.
-
-When updating beacon elements in a non-transmitted BSS,
-also update the hidden sub-entries to the same beacon
-elements, so that a future update through other paths
-won't trigger a WARN_ON().
-
-The warning is triggered because the beacon elements in
-the hidden BSSes that are children of the BSS should
-always be the same as in the parent.

-
-commit 8f9dcc29566626f683843ccac6113a12208315ca upstream.

-The following is from a system that went OOM due to a memory leak:

-wlan0: moving STA 74:83:c2:64:0b:87 to state 2
-wlan0: moving STA 74:83:c2:64:0b:87 to state 3
-.

-wlan0: expiring inactive not authorized STA 74:83:c2:64:0b:87
-wlan0: moving STA 74:83:c2:64:0b:87 to state 2
-wlan0: moving STA 74:83:c2:64:0b:87 to state 1
-wlan0: Removed STA 74:83:c2:64:0b:87
-wlan0: Destroyed STA 74:83:c2:64:0b:87
-
-The ieee80211_ibss_finish_sta() is called twice on the same STA from 2
-different locations. On the second attempt, the allocated STA is not
-destroyed creating a kernel memory leak.
-
-This is happening because sta_info_insert_finish() does not call
-sta_info_free() the second time when the STA already exists (returns
--EEXIST). Note that the caller sta_info_insert_rcu() assumes STA is
-destroyed upon errors.
-
-Same fix is applied to -ENOMEM.

-Subject: [PATCH] wifi: mac80211: Don't finalize CSA in IBSS mode if state is
- disconnected
-
-commit 15bc8966b6d3a5b9bfe4c9facfa02f2b69b1e5f0 upstream.
-
-When we are not connected to a channel, sending channel "switch"
-announcement doesn't make any sense.
-
-The BSS list is empty in that case. This causes the for loop in
-cfg80211_get_bss() to be bypassed, so the function returns NULL
-(check line 1424 of net/wireless/scan.c), causing the WARN_ON()
-in ieee80211_ibss_csa_beacon() to get triggered (check line 500
-of net/mac80211/ibss.c), which was consequently reported on the
-syzkaller dashboard.
-
-Thus, check if we have an existing connection before generating
-the CSA beacon in ieee80211_ibss_finish_csa().

-
-commit 60deb9f10eec5c6a20252ed36238b55d8b614a2c upstream.
-
-ieee80211_scan_rx() tries to access scan_req->flags after a
-null check, but a UAF is observed when the scan is completed
-and __ieee80211_scan_completed() executes, which then calls
-cfg80211_scan_done() leading to the freeing of scan_req.
-
-Since scan_req is rcu_dereference()'d, prevent the racing in
-__ieee80211_scan_completed() by ensuring that from mac80211's
-POV it is no longer accessed from an RCU read critical section
-before we call cfg80211_scan_done().
