a8eb8e6f71 wifi: iwlegacy: 4965: fix potential off-by-one overflow in il4965_rs_fill_link_cmd()
As a result of the execution of the inner while loop, the value
of 'idx' can be equal to LINK_QUAL_MAX_RETRY_NUM. However, this
is not checked after the loop and 'idx' is used to write the
LINK_QUAL_MAX_RETRY_NUM size array 'lq_cmd->rs_table[idx]' below
in the outer loop.

The fix is to check the new value of 'idx' inside the nested loop,
and break both loops if index equals the size. Checking it at the
start is now pointless, so let's remove it.

Detected using the static analysis tool - Svace.

f276e20b18 wifi: mac80211: move interface config to new struct
We'll use bss_conf for per-link configuration later, so
move out all the non-link-specific data out into a new
struct ieee80211_vif_cfg used in the vif.

Some adjustments were done with the following spatch:

    @@
    expression sdata;
    struct ieee80211_vif *vifp;
    identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator };

(though more manual fixups were needed, e.g. replacing
"vif_cfg->" by "vif->cfg." in many files.)

046d2e7c50 mac80211: prepare sta handling for MLO support
Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.

With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.

To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.

For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.

For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.

Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.

Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

  @ieee80211_sta@
  struct ieee80211_sta *s;

efdbfa0ad0 iwlwifi: fix LED dependencies
The dependencies for LED configuration are highly inconsistent and too
complicated at the moment. One of the results is a randconfig failure I
get very rarely when LEDS_CLASS is in a loadable module, but the wireless
core is built-in:

WARNING: unmet direct dependencies detected for MAC80211_LEDS
  Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y])
  Selected by [m]:
  - IWLEGACY [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y]
  - IWLWIFI_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] && IWLWIFI [=m] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=IWLWIFI [=m]) && (IWLMVM [=m] || IWLDVM [=m])

aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_register_led':
led.c:(.text+0x60): undefined reference to `led_classdev_register_ext'
aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_unregister_leds':
led.c:(.text+0x200): undefined reference to `led_classdev_unregister'

For iwlwifi, the dependency is wrong, since this config prevents the
MAC80211_LEDS code from being part of a built-in MAC80211 driver.

For iwlegacy, this is worse because the driver tries to force-enable
the other subsystems, which is both a layering violation and a bug
because it will still fail with MAC80211=y and IWLEGACY=m, leading
to LEDS_CLASS being a module as well.

The actual link failure in the ath5k driver is a result of MAC80211_LEDS
being enabled but not usable. With the Kconfig logic fixed in the
Intel drivers, the ath5k driver works as expected again.

fa7845cfd5 treewide: Replace open-coded flex arrays in unions
In support of enabling -Warray-bounds and -Wzero-length-bounds and
correctly handling run-time memcpy() bounds checking, replace all
open-coded flexible arrays (i.e. 0-element arrays) in unions with the
DECLARE_FLEX_ARRAY() helper macro.

This fixes warnings such as:

fs/hpfs/anode.c: In function 'hpfs_add_sector_to_btree':

ebe9e6514b intel: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

It has been compile tested.

Change the empty debug macros to no_printk(), which avoids the
warnings and adds useful format string checks.

but we continue to process, what makes no sense since tid is not
initialized. Non QOS frame should never happen when aggregation
is enabled on queue, so do not process that.

e4ff7d6b8c net: ipw2x00,iwlegacy,iwlwifi: Remove in_interrupt() from debug macros
The usage of in_interrupt() in non-core code is phased out.

The debugging macros in these drivers use in_interrupt() to print 'I' or
'U' depending on the return value of in_interrupt(). While 'U' is confusing
at best and 'I' is not really describing the actual context (hard interupt,
soft interrupt, bottom half disabled section) these debug macros originate
from the pre ftrace kernel era and their value today is questionable. They
probably should be removed completely.

The macros weere added initially for ipw2100 and then spreaded when the
driver was forked.

Remove the in_interrupt() usage at least..

3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

9018fd7f2a iwlegacy: Check the return value of pcie_capability_read_*()
On failure pcie_capability_read_dword() sets it's last parameter, val
to 0. However, with Patch 14/14, it is possible that val is set to ~0 on
failure. This would introduce a bug because (x & x) == (~0 & x).

This bug can be avoided without changing the function's behaviour if the
return value of pcie_capability_read_dword is checked to confirm success.

Check the return value of pcie_capability_read_dword() to ensure success.

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

8863b1212a iwlegacy: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

6cb5f3ea46 mac80211: populate debugfs only after cfg80211 init
When fixing the initialization race, we neglected to account for
the fact that debugfs is initialized in wiphy_register(), and
some debugfs things went missing (or rather were rerooted to the
global debugfs root).

Fix this by adding debugfs entries only after wiphy_register().
This requires some changes in the rate control code since it
currently adds debugfs at alloc time, which can no longer be
done after the reordering.

c2f9a4e4a5 iwlegacy: ensure loop counter addr does not wrap and cause an infinite loop
The loop counter addr is a u16 where as the upper limit of the loop
is an int. In the unlikely event that the il->cfg->eeprom_size is
greater than 64K then we end up with an infinite loop since addr will
wrap around an never reach upper loop limit. Fix this by making addr
an int.

2ce113de31 mac80211: simplify TX aggregation start
There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.

Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.
