Revert "wlcore: Adding suppoprt for IGTK key in wlcore driver"

2020-09-07T08:39:32+00:00

This patch causes a regression betwen Kernel 5.7 and 5.8 at wlcore:
with it applied, WiFi stops working, and the Kernel starts printing
this message every second:

mwifiex: Increase AES key storage size to 256 bits

2020-08-27T13:16:04+00:00

Following commit e18696786548 ("mwifiex: Prevent memory corruption
handling keys") the mwifiex driver fails to authenticate with certain
networks, specifically networks with 256 bit keys, and repeatedly asks
for the password. The kernel log repeats the following lines (id and
bssid redacted):

    mwifiex_pcie 0000:01:00.0: info: trying to associate to '' bssid 
    mwifiex_pcie 0000:01:00.0: info: associated to bssid  successfully
    mwifiex_pcie 0000:01:00.0: crypto keys added
    mwifiex_pcie 0000:01:00.0: info: successfully disconnected from : reason code 3

Tracking down this problem lead to the overflow check introduced by the
aforementioned commit into mwifiex_ret_802_11_key_material_v2(). This
check fails on networks with 256 bit keys due to the current storage
size for AES keys in struct mwifiex_aes_param being only 128 bit.

To fix this issue, increase the storage size for AES keys to 256 bit.

mt76: mt7915: use ieee80211_free_txskb to free tx skbs

2020-08-27T13:13:01+00:00

Using dev_kfree_skb for tx skbs breaks AQL. This worked until now only
by accident, because a mac80211 issue breaks AQL on drivers with firmware
rate control that report the rate via ieee80211_tx_status_ext as struct
rate_info.

mt76: mt7615: use v1 MCU API on MT7615 to fix issues with adding/removing stations

2020-08-27T13:12:19+00:00

The implementation of embedding WTBL update inside the STA_REC update is buggy
on the MT7615 v2 firmware. This leads to connection issues after a station has
connected and disconnected again.

Switch to the v1 MCU API ops, since they have received much more testing and
should be more stable.

On MT7622 and later, the v2 API is more actively used, so we should keep using
it as well.

brcmfmac: reserve tx credit only when txctl is ready to send

2020-08-18T14:32:22+00:00

The 4329 throughput drops from 40.2 Mbits/sec to 190 Kbits/sec in 2G
11n mode because the commit b41c232d33666 ("brcmfmac: reserve 2 credits
for host tx control path"). To fix the issue, host driver only reserves
tx control credit when there is a txctl frame is pending to send. And
we also check available credit by using "not equal to 0" instead of
"greater than 0" because tx_max and tx_seq are circled positive numbers.

rtl818x: constify ioreadX() iomem argument (as in generic implementation)

2020-08-15T02:56:57+00:00

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

mm, treewide: rename kzfree() to kfree_sensitive()

2020-08-07T18:33:22+00:00

As said by Linus:

  A symmetric naming is only helpful if it implies symmetries in use.
  Otherwise it's actively misleading.

  In "kzalloc()", the z is meaningful and an important part of what the
  caller wants.

  In "kzfree()", the z is actively detrimental, because maybe in the
  future we really _might_ want to use that "memfill(0xdeadbeef)" or
  something. The "zero" part of the interface isn't even _relevant_.

The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.

Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.

The renaming is done by using the command sequence:

  git grep -w --name-only kzfree |\
  xargs sed -i 's/kzfree/kfree_sensitive/'

followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.
