f5034bcf68 wifi: iwlwifi: mvm: Don't send MAC CTXT cmd after deauthorization
We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames
if we're associated but not authorized, because we don't have the
keys in that stage, and after authorization - we sent the cmd again
to ask the FW to pass MCAST, as we have the keys now.
The patch linked below was changing this strategy to always allow
MCAST frames, and if we're not authorized - the driver will drop them.
But we're still sending the MAC CTXT cmd after deaouthorization even
though we don't tell the FW to not pass MCAST frames anymore.
Basically we don't tell the FW anything new with this cmd.
Fix this by not sending MAC CTXT command after deauthorization.
For authorization we're sending the cmd to configure other changes too,
so keep it.

e861033944 wifi: iwlwifi: mvm: select ptp cross timestamp from multiple reads
iwl_mvm_get_sync_time() reads the gp2 from the device and then
reads the system clock. Since the two reads are not done atomically,
unexpected delays may happen between the two reads (e.g. context
switch) which make it inaccurate.
In order to improve the accuracy of the cross timestamp, call
iwl_mvm_get_sync_time() multiple times in a loop and take the
result in which the difference between the two clock is the smallest.

a2f49f7d52 wifi: iwlwifi: mvm: implement PHC clock adjustments
Implement the following PHC operations:
1. adjtime - for adding an offset to the PHC clock time.
2. adjfine - for adjusting the PHC clock frequency.
3. gettime64 - for getting the PHC clock time. This function returns
   the time as adjusted by adjtime and adjfine.

The adjusted time will also be used for time sync frames timestamping.

c7eca79def wifi: iwlwifi: mvm: report hardware timestamps in RX/TX status
For TM/FTM frames, report the hardware timestamps reported by the
fw as part of the RX/TX status. Since the fw reports the timestamps
in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled
when disconnected. For AP interface, only the first station will
have timestamping enabled since the fw only supports timestamping
for one peer.

 * in this case we also clobber a previous load/setting
 * if iwl_uefi_get_reduced_power() returns an ERR_PTR() we

Refactor MAC_CONTEXT_CMD sending flow:

1. As the new MLD API is introduced, there are some common fields in

has common fields with the link and mac commands of the new MLD API.
Put this common parts in functions so it can be used later by the

2. Use iwl_mvm_mac_ctxt_send_cmd when removing a mac instead of
implementing the same functionality once again.

3. Change the debug print when sending the command to be more specific,
so it will be easy to distinguish later if the old or new mac command

9c4f15cadc wifi: iwlwifi: mvm: Refactor STA_HE_CTXT_CMD sending flow
Refactor STA_HE_CTXT_CMD sending flow:

1. As the new MLD API is introduced, there are some common fields in
both the old and new APIs. The STA_HE_CTXT_CMD of the non-MLD API
has common fields with the link and mac commands of the new MLD API.
Put this common parts in functions so it can be used later by the
new MLD API.

2. The HE capability which indicates whether the NIC is ack-enabled or
not is the same for all bands. No need to take it from the specific
band which is currently in use. Take it from the low band - this
simplifies the code and doesn't require a phy_ctxt.

0936998393 wifi: iwlwifi: mvm: avoid sta lookup in queue alloc
In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).

However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.

This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

a23c82e006 wifi: ipw2x00: convert ipw_fw_error->elem to flexible array[]
The ipw_fw_error structure contains a payload[] flexible array as well as
two pointers to this array area, ->elem, and ->log. The total size of the
allocated structure is computed without use of the <linux/overflow.h>
macros.

There's no reason to keep both a payload[] and an extra pointer to both the
elem and log members. Convert the elem pointer member into the flexible
array member, removing payload.

Fix the allocation of the ipw_fw_error structure to use size_add(),
struct_size(), and array_size() to compute the allocation. This ensures
that any overflow saturates at SIZE_MAX rather than overflowing and
potentially allowing an undersized allocation.

Before the structure change, the layout of ipw_fw_error was:

struct ipw_fw_error {
        long unsigned int          jiffies;              /*     0     8 */
        u32                        status;               /*     8     4 */
        u32                        config;               /*    12     4 */
        u32                        elem_len;             /*    16     4 */
        u32                        log_len;              /*    20     4 */
        struct ipw_error_elem *    elem;                 /*    24     8 */
        struct ipw_event *         log;                  /*    32     8 */
        u8                         payload[];            /*    40     0 */

        /* size: 40, cachelines: 1, members: 8 */
        /* last cacheline: 40 bytes */
};

After this change, the layout is now:

struct ipw_fw_error {
        long unsigned int          jiffies;              /*     0     8 */
        u32                        status;               /*     8     4 */
        u32                        config;               /*    12     4 */
        u32                        elem_len;             /*    16     4 */
        u32                        log_len;              /*    20     4 */
        struct ipw_event *         log;                  /*    24     8 */
        struct ipw_error_elem      elem[];               /*    32     0 */

        /* size: 32, cachelines: 1, members: 7 */
        /* last cacheline: 32 bytes */
};

This saves a total of 8 bytes for every ipw_fw_error allocation, and
removes the risk of a potential overflow on the allocation.

da1185449c wifi: iwlwifi: mvm: fix EOF bit reporting
In monitor mode, we try to report the EOF bit on the
first MPDU of an A-MPDU (hardware duplicates this bit
over all MPDUs, so it's only trustable on the first).

However, due to reshuffling in an ealier commit, the
toggle_bit != mvm->ampdu_toggle logic can no longer
work since mvm->ampdu_toggle is now set before this
code runs.

Fix this by tracking the first_subframe status in the
phy data struct and using that instead of checking.

set to IWL_MVM_INVALID_QUEUE == 0xffff, so the BIT() here

Since we don't need the tfd_queue_msk value for the new TX
API at all, simply fill it in only for the old API.
