Johannes Berg 41fff83fe6 wifi: iwlwifi: pcie: check for WiAMT/CSME presence
In order to know whether or not a product reset can safely
be done (without risking locking up the system completely),
check for ME presence with the known methods.

Since adding __counted_by(n_channels) to struct cfg80211_scan_request,
anything adding to the channels array must increment n_channels first.

Currently the SAE_H2E selector already exists, which needs to be
implemented by the SME. As new such selectors might be added in the
future, add a feature to permit userspace to report a selector as
supported.

If not given, the kernel should assume that userspace does support
SAE_H2E.

Johannes Berg da7f40c05c wifi: mac80211: add some support for RX OMI power saving
In order to save power, it can be desirable to change the
RX operating mode using OMI to reduce the bandwidth. As the
handshake must be done in the HTC+ field, it cannot be done
by mac80211 directly, so expose functions to the driver to
request and finalize the necessary updates.

Note that RX OMI really only changes what the peer (AP) will
transmit to us, but in order to use it to actually save some
power (by reducing the listen bandwidth) we also update rate
scaling and then the channel context's mindef accordingly.

The updates are split into two in order to sequence them
correctly, when reducing bandwidth first reduce the rate
scaling and thus TX, then send OMI, then reduce the listen
bandwidth (chandef); when increasing bandwidth this is the
other way around. This also requires tracking in different
variables which part is applicable already.

Emmanuel Grumbach 79f4b6934d wifi: iwlwifi: mvm: remove unneeded NULL pointer checks
Smatch reported that we dereference the data pointer to calculate the
expected length before we check it's not NULL. While this is true (and
hence needs to be fixed), this will never happen because the data
pointer comes from struct iwl_rx_packet object which has the following
layout:

struct iwl_rx_packet {
        __le32 len_n_flags;
        struct iwl_cmd_header hdr;
        u8 data[];
} __packed;

So, if the pointer to iwl_rx_packet is valid, data will be valid as
well.

Remove the NULL pointer check on 'data' to avoid confusing smatch.
Also remove the check from similar functions in the same flow that were
cargo cult copy-pasted.

Johannes Berg c866a98523 wifi: iwlwifi: mvm: fix add stream vs. restart race
My recent restart related work has made this race more likely
to happen and we've now noticed it, but it seems that it was
always possible. The race is that the add stream work can be
scheduled just before a restart is scheduled and then execute
before the restart, accessing the device while it's doing the
restart and not accessible.

To fix this, check if the device is restarting and abort the
work in that case. Reschedule it after the restart as well.

iwl_acpi_get_dsm_integer returns immediately without freeing
it if the expected size is more than 8 bytes. Fix that.

Note that with the current code this will never happen, since the caller
of iwl_acpi_get_dsm_integer already checks that the expected size if
either 1 or 4 bytes, so it can't exceed 8 bytes.

While at it, print the DSM value instead of the return value, as this
was the intention in the first place.
