Johannes Berg says: ==================== This is relatively small, mostly to get the SG/crypto from stack removal fix that crashes things when VMAP stack is used in conjunction with software crypto. Aside from that, we have: * a fix for AP_VLAN usage with the nl80211 frame command * two fixes (and two preparation patches) for A-MSDU, one to discard group-addressed (multicast) and unexpected 4-address A-MSDUs, the other to validate A-MSDU inner MAC addresses properly to prevent controlled port bypass ==================== Signed-off-by: David S.

Kalle Valo says: ==================== wireless-drivers fixes for 4.9 wlcore * fix a double free regression causing hard to track crashes rtl8xxxu * fix driver reload issues, a memory leak and an endian bug rtlwifi * fix a major regression introduced in 4.9 with firmware loading on certain hardware ath10k * fix regression about broken cal_data debugfs file (since 4.7) ath9k * revert temperature compensation for AR9003+ devices, it was causing too much problems ath6kl * add Dell OEM SDIO I/O for the Venue 8 Pro ==================== Signed-off-by: David S.

Commit 0b8e3c4ca29f ("ath10k: move cal data len to hw_params") broke retrieving
the calibration data from cal_data debugfs file. The length of file was always
zero. The reason is:
static ssize_t ath10k_debug_cal_data_read(struct file *file,
char __user *user_buf,
size_t count, loff_t *ppos)
{
struct ath10k *ar = file->private_data;
void *buf = file->private_data;
This is obviously bogus, private_data cannot contain both struct ath10k and the
buffer. Fix it by caching calibration data to ar->debug.cal_data. This also
allows it to be accessed when the device is not active (interface is down).
The cal_data buffer is fixed size because during the first firmware probe we
don't yet know what will be the lenght of the calibration data. It was simplest
just to use a fixed length. There's a WARN_ON() in
ath10k_debug_cal_data_fetch() if the buffer is too small.
Tested with qca988x and firmware 10.2.4.70.56.

In commit d86e64768859 ("rtlwifi: rtl818x: constify local structures"),
the configuration struct for most of the drivers was changed to be
constant. The problem is that five of the modified drivers need to be
able to update the firmware name based on the exact model of the card.
As the file names were stored in one of the members of that struct,
these drivers would fail with a kernel BUG splat when they tried to
update the firmware name.
Rather than reverting the previous commit, I used a suggestion by
Johannes Berg and made the firmware file name pointers be local to
the routines that update the software variables.
The configuration struct of rtl8192cu, which was not touched in the
previous patch, is now constantfied.

We should not accept arbitrary DA/SA inside A-MSDUs, it could be used to circumvent protections, like allowing a station to send frames and make them seem to come from somewhere else. Add the necessary infrastructure in cfg80211 to allow such checks, in further patches we'll start using them. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
There's only a single case where has_80211_header is passed as true, which is in mac80211. Given that there's only simple code that needs to be done before calling it, export that function from cfg80211 instead and let mac80211 call it itself. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
