The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
(kernel Oops) or a security flaw (overwriting memory beyond the
stack). Also, in general, as code evolves it is easy to lose track of
how big a VLA can get. Thus, we can end up having runtime failures
that are hard to debug. As part of the directive[1] to remove all VLAs
from the kernel, and build with -Wvla.
Currently rsi code uses a VLA based on a function argument to
`rsi_sdio_load_data_master_write()`. The function call chain is
Both these functions
rsi_sdio_reinit_device()
rsi_probe()
start the call chain:
rsi_hal_device_init()
rsi_load_fw()
auto_fw_upgrade()
ping_pong_write()
rsi_sdio_load_data_master_write()
[Without familiarity with the code] it appears that none of the 4 locks
mutex
rx_mutex
tx_mutex
tx_bus_mutex
are held when `rsi_sdio_load_data_master_write()` is called. It is therefore
safe to use kmalloc with GFP_KERNEL.
We can avoid using the VLA by using `kmalloc()` and free'ing the memory on all
exit paths.
Change buffer from 'u8 array' to 'u8 *'. Call `kmalloc()` to allocate memory for
the buffer. Using goto statement to call `kfree()` on all return paths.
It can be expected that this patch will result in a small increase in overhead
due to the use of `kmalloc()` however this code is only called on initialization
(and re-initialization) so this overhead should not degrade performance.

drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':

As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
(ieee80211_sta) delete will trigger the kernel panic.
This problem arise in AP + Mesh configuration, Where the current node AP VAP
and neighbor node mesh VAP MAC address are same. When the current mesh node
try to establish the mesh link with neighbor node, driver peer creation for
the neighbor mesh node fails due to duplication MAC address. Already the AP
VAP created with same MAC address.
It is caused by the following scenario steps.
Steps:
1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
fails to do the state change for a station from IEEE80211_STA_NOTEXIST
to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
called from ieee80211_add_station() to handle the new station
(neighbor mesh node) request from the wpa_supplicant.
2. Concurrently ath10k receive the sta_rc_update callback notification from
the mesh_neighbour_update() to handle the beacon frames of the above
neighbor mesh node. since its atomic callback, ath10k driver queue the
work (ath10k_sta_rc_update_wk) to handle rc update.
3. Due to driver sta_state callback fails (step 1), mac80211 free the station
object.
4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
the station object which is already deleted. so it will trigger kernel
panic.
Added the peer exist check in sta_rc_update callback before queue the work.

Added per tid sta counters for the following
- Total number MSDUs received from firmware
- Number of MSDUs received with errors like decryption, crc, mic ,etc.
- Number of MSDUs dropped in the driver
- A-MPDU/A-MSDU subframe stats
- Number of MSDUS passed to mac80211
All stats other than A-MPDU stats are only for received data frames.
A-MPDU stats might have stats for management frames when monitor
interface is active where management frames are notified both in wmi
and HTT interfaces.
These per tid stats can be enabled with tid bitmask through a debugfs
like below
echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask
tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames
The stats are read from
/sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats

The biggest changes are the bluetooth related patches to the rsi
driver. It adds a new bluetooth driver which communicates directly
with the wireless driver and the interface is defined in
include/net/rsi_91x.h.
Major changes:
wl1251
* read the MAC address from the NVS file
rtlwifi
* enable mac80211 fast-tx support
mt76
* add capability to select tx/rx antennas
mt7601
* let mac80211 validate rx CCMP Packet Number (PN)
rsi
* bluetooth: add new btrsi driver
* btcoex support with the new btrsi driver

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

When switching mac80211 to use QoS NDP, it turned out that
ath9k_htc is somehow broken by this, e.g. see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891060.
Fix this by using the new mac80211 flag to go back to the
old, incorrect, behaviour for this driver.

Set the wmediumd to the net's wmediumd when the radio gets created.
Radios created after HWSIM_CMD_REGISTER don't currently get their
data->wmediumd set and the userspace would need to reconnect to
netlink to be able to call HWSIM_CMD_REGISTER again.
Alternatively I think data->netgroup and data->wmedium could be
replaced with a pointer to hwsim_net.

skb_copy_expand without __GFP_NOWARN already does a dump_stack

When ath9k was switched over to use the mac80211 intermediate queues,
node cleanup now drains the mac80211 queues. However, this call path is
not protected by rcu_read_lock() as it was previously entirely internal
to the driver which uses its own locking.
This leads to a possible rcu_dereference() without holding
rcu_read_lock(); but only if a station is cleaned up while having
packets queued on the TXQ. Fix this by adding the rcu_read_lock() to the
caller in ath9k.
Fixes: 50f08edf98 ("ath9k: Switch to using mac80211 intermediate software queues.")

WCN3990 sends mgmt frames by reference via WMI.
The host dma maps the mgmt frame and sends the physical
address to the firmware in the wmi command. Since the
dma mapping is done in the gen_mgmt_tx and if the wmi
command send fails, the corresponding mgmt frame is
not being dma unmapped.
Fix the missing dma unmapping of mgmt tx frame when
wmi command sending fails for mgmt tx by reference
via WMI. The already exisiting mgmt tx using copy by
value does not need such dma unmapping.
Add a separate wmi-tlv op for mgmt tx via ref, which
takes care of unmapping the dma address, in case of
wmi command sending failure.

At present driver gets chan_type by referring to
IEEE80211_HT_PARAM_CHA_SEC_OFFSET, in ASSOC response. Sometimes
AP shows IEEE80211_HT_PARAM_CHA_SEC_OFFSET as above/below in
assoc response, even if the association is done on HT20 channel
only. So, it will be accurate to get econdary channel offset from
firmware.
