clang triggers a warning about oversized stack frames that gcc does not
notice because of slightly different inlining decisions:
ath/wcn36xx/smd.c:1409:5: error: stack frame size of 1040 bytes in function 'wcn36xx_smd_config_bss' [-Werror,-Wframe-larger-than=]
ath/wcn36xx/smd.c:640:5: error: stack frame size of 1032 bytes in function 'wcn36xx_smd_start_hw_scan' [-Werror,-Wframe-larger-than=]
Basically the wcn36xx_hal_start_scan_offload_req_msg,
wcn36xx_hal_config_bss_req_msg_v1, and wcn36xx_hal_config_bss_req_msg
structures are too large to be put on the kernel stack, but small
enough that gcc does not warn about them.
Use kzalloc() to allocate them all. There are similar structures in other
parts of this driver, but they are all smaller, with the next largest
stack frame at 480 bytes for wcn36xx_smd_send_beacon.

In ath6kl_htc_mbox_create(), when kzalloc() on line 2855 fails,
target->dev is assigned to NULL, and ath6kl_htc_mbox_cleanup(target) is
called on line 2885.
In ath6kl_htc_mbox_cleanup(), target->dev is used on line 2895:
ath6kl_hif_cleanup_scatter(target->dev->ar);
Thus, a null-pointer dereference may occur.
To fix this bug, kfree(target) is called and NULL is returned when
kzalloc() on line 2855 fails.

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
intended behaviour.

`dev` (struct rsi_91x_usbdev *) field of adapter
(struct rsi_91x_usbdev *) is allocated and initialized in
`rsi_init_usb_interface`. If any error is detected in information
read from the device side, `rsi_init_usb_interface` will be
freed. However, in the higher level error handling code in
`rsi_probe`, if error is detected, `rsi_91x_deinit` is called
again, in which `dev` will be freed again, resulting double free.
This patch fixes the double free by removing the free operation on
`dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also
used in `rsi_disconnect`, in that code path, the `dev` field is not
(and thus needs to be) freed.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct usb_int_regs {
...
struct reg_data regs[0];
} __packed;
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following function:
static int usb_int_regs_length(unsigned int count)
{
return sizeof(struct usb_int_regs) + count * sizeof(struct reg_data);
}

Getting RAM info just once per driver's lifetime (during chip
recognition) is not enough as it may get adjusted later (depending on
the used firmware). Subsequent inits may load different firmwares so a
full RAM recognition is required on every PCIe setup. This is especially
important since implementing hardware reset on a firmware crash.
Moreover calling brcmf_chip_get_raminfo() makes sure that RAM core is
up. It's important as having BCMA_CORE_SYS_MEM down on BCM4366 was
resulting in firmware failing to initialize and following error:
[ 65.657546] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: Invalid shared RAM address 0x04000001
This change makes brcmf_chip_get_raminfo() call during chip recognition
redundant for PCIe devices but SDIO and USB still need it and it's a
very small overhead anyway.

According to documentation IEEE80211_TX_STAT_AMPDU_NO_BACK is suppose
to be used when we do not recive BA (BlockAck). However on rt2x00 we
use it when remote station fail to decode one or more subframes within
AMPDU (some bits are not set in BlockAck bitmap). Setting the flag result
in sent of BAR (BlockAck Request) frame and this might result of abuse
of BA session, since remote station can sent BA with incorrect
sequence numbers after receiving BAR. This problem is visible especially
when connecting two rt2800 devices.
Previously I observed some performance benefits when using the flag
when connecting with iwlwifi devices. But currently possibly due
to reacent changes in rt2x00 removing the flag has no effect on
those test cases.
So remove the IEEE80211_TX_STAT_AMPDU_NO_BACK.
