+Subject: [PATCH] brcmfmac: fix Oops when bringing up interface during USB
+ disconnect
+
+Fix a race which leads to an Oops with NULL pointer dereference. The
+dereference is in brcmf_config_dongle() when cfg_to_ndev() attempts to get
+net_device structure of interface with index 0 via if2bss mapping. This
+shouldn't fail because of check for bus being ready in brcmf_netdev_open(),
+but it's not synchronised with USB disconnect and there is a race: after
+the check the bus can be marked down and the mapping for interface 0 may be
+gone.
+
+Solve this by modifying disconnect handling so that the removal of mapping
+of ifidx to brcmf_if structure happens after netdev removal (which is
+synchronous with brcmf_netdev_open() thanks to rtln being locked in
+devinet_ioctl()). This assures brcmf_netdev_open() returns before the
+mapping is removed during disconnect.
+
+Unable to handle kernel NULL pointer dereference at virtual address 00000008

+Currently if the call to brcmf_sdiod_set_backplane_window fails then

+Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for ACEPC T8 and T11
+ mini PCs
+
+The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor
+and product_name DMI strings, without this patch brcmfmac will try to load:
+"brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which
+is way too generic.
+
+The DMI strings on which we are matching are somewhat generic too, but
+"To be filled by O.E.M." is less common then "Default string" and the
+system-sku and bios-version strings are pretty unique. Beside the DMI
+strings we also check the wifi-module chip-id and revision. I'm confident
+that the combination of all this is unique.
+
+Both the T8 and T11 use the same wifi-module, this commit adds DMI
+quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .

+Subject: [PATCH] brcm80211: potential NULL dereference in
+ brcmf_cfg80211_vndr_cmds_dcmd_handler()
+
+If "ret_len" is negative then it could lead to a NULL dereference.
+
+The "ret_len" value comes from nl80211_vendor_cmd(), if it's negative
+then we don't allocate the "dcmd_buf" buffer. Then we pass "ret_len" to
+brcmf_fil_cmd_data_set() where it is cast to a very high u32 value.
+Most of the functions in that call tree check whether the buffer we pass
+is NULL but there are at least a couple places which don't such as
+brcmf_dbg_hex_dump() and brcmf_msgbuf_query_dcmd(). We memcpy() to and
+from the buffer so it would result in a NULL dereference.
+
+The fix is to change the types so that "ret_len" can't be negative. (If
+we memcpy() zero bytes to NULL, that's a no-op and doesn't cause an
+issue).

+Some PCIE firmwares drop txstatus if pktid is 0 and make packet held in

+
+To be compatible with all firmwares, host should set txflow request id

+Subject: [PATCH] brcmfmac: print firmware messages after a firmware crash
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Normally firmware messages are printed with debugging enabled only. It's
+a good idea as firmware may print a lot of messages that normal users
+don't need to care about.
+
+However, on firmware crash, it may be very helpful to log all recent
+messages. There is almost always a backtrace available as well as rought
+info on the latest actions/state.
