There are special kinds of FW such as WMI only which
are used for testing, diagnostics and other specific
scenario.
Such FW is loaded during driver probe and the driver
disallows enabling any network interface, to avoid
operational issues.
In many cases it is used to debug early versions
of FW with new features, which sometimes fail
on startup.
Currently when such FW fails to load (for example,
because of init failure), the driver probe would fail
and shutdown the device making it difficult to debug
the early failure.
To fix this, ignore load failures in WMI only FW and
allow driver probe to succeed, making it possible to
continue and debug the FW load failure.

Due to race condition between HW writing the status message and

The tlv targets such as WCN3990 send more data in the chan info event, which is

When the FW bundles multiple packets, pkt->act_len may be incorrect
as it refers to the first packet only (however, the FW will only
bundle packets that fit into the same pkt->alloc_len).
Before this patch, the skb length would be set (incorrectly) to
pkt->act_len in ath10k_sdio_mbox_rx_packet, and then later manually
adjusted in ath10k_sdio_mbox_rx_process_packet.
The first problem is that ath10k_sdio_mbox_rx_process_packet does not
use proper skb_put commands to adjust the length (it directly changes
skb->len), so we end up with a mismatch between skb->head + skb->tail
and skb->data + skb->len. This is quite serious, and causes corruptions
in the TCP stack, as the stack tries to coalesce packets, and relies
on skb->tail being correct (that is, skb_tail_pointer must point to
the first byte_after_ the data).
Instead of re-adjusting the size in ath10k_sdio_mbox_rx_process_packet,
this moves the code to ath10k_sdio_mbox_rx_packet, and also add a
bounds check, as skb_put would crash the kernel if not enough space is
available.

For sdio chip, if the rssi is not good, then it have some retry,
firmware will indicate the msdu list of a ppdu with a hole, it
means it lost the hole msdu, after the msdu retry from AP, the
hole msdu will indicate from firmware later. The hole msdu's PN
check will fail and the hole msdu will be dropped.
PN check fail example:
Sequence number PN number PN check status
3814 6101 success
3815 6102 success
3816 6103 success
3818 6105 success
3819 6106 success
3820 6107 success
3817 6104 fail
The correct logic is reorder the msdu list and then do PN check.
ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic
and then do PN check in ieee80211_rx_h_decrypt of mac80211.
example after reorder:
Sequence number PN number PN check status

The `ar_usb` field of `ath6kl_usb_pipe_usb_pipe` objects
are initialized to point to the containing `ath6kl_usb` object
according to endpoint descriptors read from the device side, as shown
below in `ath6kl_usb_setup_pipe_resources`:
for (i = 0; i < iface_desc->desc.bNumEndpoints; ++i) {
endpoint = &iface_desc->endpoint[i].desc;
// get the address from endpoint descriptor
pipe_num = ath6kl_usb_get_logical_pipe_num(ar_usb,
endpoint->bEndpointAddress,
&urbcount);
......
// select the pipe object
pipe = &ar_usb->pipes[pipe_num];
// initialize the ar_usb field
pipe->ar_usb = ar_usb;
}
The driver assumes that the addresses reported in endpoint
descriptors from device side to be complete. If a device is
malicious and does not report complete addresses, it may trigger
NULL-ptr-deref `ath6kl_usb_alloc_urb_from_pipe` and
`ath6kl_usb_free_urb_to_pipe`.
This patch fixes the bug by preventing potential NULL-ptr-deref
(CVE-2019-15098).

Atheros cards with a AR92XX generation (and older) chip usually
store their pci(e) initialization vectors on an external eeprom chip.
However these chips technically don't need the eeprom chip attached,
the AR9280 Datasheet in section "6.1.2 DEVICE_ID" describes that
"... if the EEPROM content is not valid, a value of 0xFF1C returns
when read from the register". So, they will show up on the system's
pci bus. However in that state, ath9k can't load, since it relies
on having the correct pci-id, otherwise it doesn't know what chip it
actually is. This happens on many embedded devices like routers
and accesspoint since they want to keep the BOM low and store the
pci(e) initialization vectors together with the calibration data
on the system's FLASH, which is out of reach of the ath9k chip.
Furthermore, Some devices (like the Cisco Meraki Z1 Cloud Managed
Teleworker Gateway) need to be able to initialize the PCIe wifi device.
Normally, this should be done as a pci quirk during the early stages of
booting linux. However, this isn't possible for devices which have the
init code for the Atheros chip stored on NAND in an UBI volume.
Hence, this module can be used to initialize the chip when the
user-space is ready to extract the init code.
Martin Blumenstingl prodived the following fixes:
owl-loader: add support for OWL emulation PCI devices
owl-loader: don't re-scan the bus when ath9k_pci_fixup failed
owl-loader: use dev_* instead of pr_* logging functions
owl-loader: auto-generate the eeprom filename as fallback
owl-loader: add a debug message when swapping the eeprom data
owl-loader: add missing newlines in log messages

There are several occasions where a negative cid value is passed
into wil_cid_valid and this is converted into a u8 causing the
range check of cid >= 0 to always succeed. Fix this by making
the cid argument an int to handle any -ve error value of cid.
An example of this behaviour is in wil_cfg80211_dump_station,
where cid is assigned -ENOENT if the call to wil_find_cid_by_idx
fails, and this -ve value is passed to wil_cid_valid. I believe
that the conversion of -ENOENT to the u8 value 254 which is
greater than wil->max_assoc_sta causes wil_find_cid_by_idx to
currently work fine, but I think is by luck and not the

When this attribute is not set it means driver does not support EDMG.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth
configurations supported by the driver.
Additional two new attributes are used by the userspace for connect
command and for AP configuration:
NL80211_ATTR_WIPHY_EDMG_CHANNELS
NL80211_ATTR_WIPHY_EDMG_BW_CONFIG
New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver
and used for bitrate calculation that will take into account EDMG
according to the 802.11ay specification.

This low level driver can find it useful to get the vif
when a remain on channel session is cancelled.
iwlwifi will need this soon.

In preparation for unifying the skb_frag and bio_vec, use the fine
accessors which already exist and use skb_frag_t instead of
struct skb_frag_struct.

In my previous commit to validate a policy I neglected to
actually add one to the few drivers using vendor commands,
fix that now.

As clang points out, the vht_pfr is assigned to a struct member
without being initialized in one case:
drivers/net/wireless/ath/ath10k/mac.c:7528:7: error: variable 'vht_pfr' is used uninitialized whenever 'if' condition
is false [-Werror,-Wsometimes-uninitialized]
if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7551:20: note: uninitialized use occurs here
arvif->vht_pfr = vht_pfr;
^~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7528:3: note: remove the 'if' if its condition is always true
if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7483:12: note: initialize the variable 'vht_pfr' to silence this warning
u8 vht_pfr;
Add an explicit but probably incorrect initialization here.
I suspect we want a better fix here, but chose this approach to
illustrate the issue.

ath10k will receive some message with invalid peer id from firmware.
reason is:
There are incoming frames to MAC hardware that NOT find relative
address search table, then peer id is invalid set by MAC hardware,
it is hardware's logic, so fix it in ath10k will be more convenient.
log:
ath10k_sdio mmc1:0001:1: Got RX ind from invalid peer: 65535

Currently the memory allocated for qmi handle is
not being freed during de-init which leads to memory leak.
Free the allocated qmi memory in qmi deinit
to avoid memory leak.
