kmemdup() at line 2735 is not duplicating enough memory for
notif->tid_tear_down and notif->station_id. As it only duplicates
612 bytes: up to offsetofend(struct iwl_wowlan_info_notif,
received_beacons), this is the range of [0, 612) bytes.
2735 notif = kmemdup(notif_v1,
2736 offsetofend(struct iwl_wowlan_info_notif,
2737 received_beacons),
2738 GFP_ATOMIC);
which evidently does not cover bytes 612 and 613 for members
tid_tear_down and station_id in struct iwl_wowlan_info_notif.
See below:
$ pahole -C iwl_wowlan_info_notif drivers/net/wireless/intel/iwlwifi/mvm/d3.o
struct iwl_wowlan_info_notif {
struct iwl_wowlan_gtk_status_v3 gtk[2]; /* 0 488 */
/* --- cacheline 7 boundary (448 bytes) was 40 bytes ago --- */
struct iwl_wowlan_igtk_status igtk[2]; /* 488 80 */
/* --- cacheline 8 boundary (512 bytes) was 56 bytes ago --- */
__le64 replay_ctr; /* 568 8 */
/* --- cacheline 9 boundary (576 bytes) --- */
__le16 pattern_number; /* 576 2 */
__le16 reserved1; /* 578 2 */
__le16 qos_seq_ctr[8]; /* 580 16 */
__le32 wakeup_reasons; /* 596 4 */
__le32 num_of_gtk_rekeys; /* 600 4 */
__le32 transmitted_ndps; /* 604 4 */
__le32 received_beacons; /* 608 4 */
u8 tid_tear_down; /* 612 1 */
u8 station_id; /* 613 1 */
u8 reserved2[2]; /* 614 2 */
/* size: 616, cachelines: 10, members: 13 */
/* last cacheline: 40 bytes */
};
Therefore, when the following assignments take place, actually no memory
has been allocated for those objects:
2743 notif->tid_tear_down = notif_v1->tid_tear_down;
2744 notif->station_id = notif_v1->station_id;
Fix this by allocating space for the whole notif object and zero out the
remaining space in memory after member station_id.
This also fixes the following -Warray-bounds issues:

This driver relies on IEEE80211_CONF_PS of hw->conf.flags to turn off PS or
turn on dynamic PS controlled by driver and firmware. Though this would be
incorrect, it did work before because the flag is always recalculated until
the commit 28977e790b5d ("wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PS")
is introduced by kernel 5.20 to skip to recalculate IEEE80211_CONF_PS
of hw->conf.flags if driver sets SUPPORTS_DYNAMIC_PS.
Correct this by doing recalculation while BSS_CHANGED_PS is changed and
interface is added or removed. For now, it is allowed to enter PS only if
single one station vif is working, and it could possible to have PS per
vif after firmware can support it. Without this fix, driver doesn't
enter PS anymore that causes higher power consumption.

clang warns about an unpacked structure inside of a packed one:
drivers/net/wireless/broadcom/b43/b43.h:654:4: error: field data within 'struct b43_iv' is less aligned than 'union (unnamed union at /home/arnd/arm-soc/drivers/net/wireless/broadcom/b43/b43.h:651:2)' and is usually due to 'struct b43_iv' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
The problem here is that the anonymous union has the default alignment
from its members, apparently because the original author mixed up the
placement of the __packed attribute by placing it next to the struct
member rather than the union definition. As the struct itself is
also marked as __packed, there is no need to mark its members, so just
move the annotation to the inner type instead.
As Michael noted, the same problem is present in b43legacy, so
change both at the same time.

The Allwinner sunxi-mmc controller cannot handle word (16 bit)
transfers. So and sdio_{read,write}w fails with messages like the
following example using an RTL8822BS (but the same problems were also
observed with RTL8822CS and RTL8723DS chips):
rtw_8822bs mmc1:0001:1: Firmware version 27.2.0, H2C version 13
sunxi-mmc 4021000.mmc: unaligned scatterlist: os f80 length 2
sunxi-mmc 4021000.mmc: map DMA failed
rtw_8822bs mmc1:0001:1: sdio read16 failed (0x10230): -22
Use two consecutive single byte accesses for word operations instead. It
turns out that upon closer inspection this is also what the vendor
driver does, even though it does have support for sdio_{read,write}w. So
we can conclude that the rtw88 chips do support word access but only on
SDIO controllers that also support it. Since there's no way to detect if
the controller supports word access or not the rtw88 sdio driver
switches to the easiest approach: avoiding word access.

The rs_drv_get_rate flow reads the lq_sta to return the optimal rate
for tx frames. This read flow is not protected thereby leaving
a small window, a few instructions wide, open to contention by an
asynchronous rate update. Indeed this race condition was hit and the
update occurred in the middle of the read.

n_channels much larger than the command response can be,
we might copy far too much (uninitialized) memory and
even crash if the n_channels is large enough to make it

Fix that by checking the lengths. Doing a < comparison

The DBGI dump is (unsurprisingly) of type DBGI, not SRAM.
This leads to bad register accesses because the union is
built differently, there's no allocation ID, and thus the
allocation ID ends up being 0x8000.
Note that this was already wrong for DRAM vs. SMEM since
they use different parts of the union, but the allocation
ID is at the same place, so it worked.
Fix all of this but set the allocation ID in a way that
the offset calculation ends up without any offset.

so just directly error out on a NULL id there.

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of
them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems.

"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems"

A fairly standard release for SPI with the exception of a change to the
API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical
changes throughout the tree which have been cooking in -next happily for
a while. There's also a new API to allow us to TPM chips on half duplex
controllers.
There's three commits in here that were mangled by a bad interaction
between the alsa-devel mailing list software and b4, I didn't notice
until there were merges on top with it being SPI not ALSA. It seemed
clear enough to not be worth going back and fixing.
- Refactoring in preparation for supporting multiple chip selects for a
single device, needed by some flash devices, which required a change
in the SPI device API visible throughout the tree.
- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI.
- Optimisation for large transfers on fsl-cpm devices.
- Cleanups around device property use which fix some sisues with
fwnode.
- Use of both void remove() and devm_platform_.*ioremap_resource().
- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
Intel MetorLake-S and StarFive J7110 QuadSPI.
The final commit converting to DEV_PM_OPS() was applied late to fix a
warning that was introduced by some of the earlier work.

Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device.
- Add basic LED support for switch/phy.
- Add NAPI documentation, stop relaying on external links.
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory
work to make the hardware timestamping layer selectable by user
space.
- Add transceiver support and improve the error messages for CAN-FD
controllers.

This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa.
Turns out the channelmap variable is not actually read-only, it's modified
through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function,
so making it read-only causes page faults when that code is hit.

This driver does not actually use the ISA DMA API, it is purely

The goal of writing 0x6954341e / 0x6955341e to REG_OFDM0_XA_AGC_CORE1
appears to be setting the initial gain, which is stored in bits 0..6.
Bits 7..31 are the same as what the phy init tables write.
Modify only bits 0..6 so that we don't have to care about the values
of the others. This way we don't have to add another "else if" for the
RTL8192FU.
Why we need to change the initial gain from the default 0x20 to 0x1e?
Not sure. Some of the vendor drivers change it to 0x1e before scanning
and then restore it to the original value after.

Also add rtl8xxxu_write32_mask, rtl8xxxu_write_rfreg_mask.
These helper functions make it easier to modify only parts of a register
by eliminating the call to the register reading function and the bit
manipulations.

Most devices have a vendor name, product name, and serial number in the
efuse, but it's pretty useless. It duplicates the information already
printed by the USB subsystem:

We have to call rtw8821c_switch_rf_set() with SWITCH_TO_WLG or
SWITCH_TO_BTG according to the chip variant as denoted in rfe_option.
The information which argument to use for which variant has been
taken from the vendor driver.

According to the vendor driver the pkg_type has to be set to '1'
for some rtw8821c variants. As the pkg_type has been hardcoded to
'0', add a field for it in struct rtw_hal and set this correctly
in the rtw8821c part.
With this parsing of a rtw_table is influenced and check_positive()
in phy.c returns true for some cases here. The same is done in the
vendor driver. However, this has no visible effect on the driver
here.

On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the
vendor driver suggests that the field width of rfe_option is 5 bit,
so rfe_option should be masked with 0x1f.
Without this the rfe_option comparisons with 2 further down the
driver evaluate as false when they should really evaluate as true.
The effect is that 2G channels do not work.
rfe_option is also used as an array index into rtw8821c_rfe_defs[].
rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support,
likely because rfe_option reads as 0x22. As this now becomes 0x2,
rtw8821c_rfe_defs[34] is no longer used and can be removed.
Note that this might not be the whole truth. In the vendor driver
there are indeed places where the unmasked rfe_option value is used.
However, the driver has several places where rfe_option is tested
with the pattern if (rfe_option == 2 || rfe_option == 0x22) or
if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5)
has no influence on the code path taken. We therefore mask BIT(5)
out from rfe_option entirely until this assumption is proved wrong
by some chip variant we do not know yet.

The RTW88 chipsets have four different priority queues in hardware. For
the USB type chipsets the packets destined for a specific priority queue
must be sent through the endpoint corresponding to the queue. This was
not fully understood when porting from the RTW88 USB out of tree driver
and thus violated.
This patch implements the qsel to endpoint mapping as in
get_usb_bulkout_id_88xx() in the downstream driver.
Without this the driver often issues "timed out to flush queue 3"
warnings and often TX stalls completely.
