The cpts can timestmap only ptp packets at this moment, so driver
cannot mark every packet as though it's going to be timestamped,
only because h/w timestamping for given skb is enabled with
SKBTX_HW_TSTAMP. It doesn't allow to use sw timestamping, as result
outgoing packet is not timestamped at all if it's not PTP and h/w
timestamping is enabled. So, fix it by setting SKBTX_IN_PROGRESS
only for PTP packets.

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.
By using phy-mode = "internal" we permit to have an external PHY with
the same mode than the internal one.

connect handlers
Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in bind() and connect()
handlers of the Bluetooth sockets. Since neither syscall enforces a minimum
size of the corresponding memory region, very short sockaddrs (zero or one
byte long) result in operating on uninitialized memory while referencing
sa_family.

Bluetooth hci uses ordered HIGHPRI, MEM_RECLAIM workqueues. It's
likely that the flags came from mechanical conversion from
create_singlethread_workqueue(). Bluetooth shouldn't be depended upon
for memory reclaim and the spurious MEM_RECLAIM flag can trigger the
following warning. Remove WQ_MEM_RECLAIM and convert to
alloc_ordered_workqueue() while at it.

When hostapd adds a station, it does so before sending the association
response frame, so that it can indicate the correct status code in the
response.
However, when this then fails, or the association response already is
a reject for some other reason, then there's no station entry and thus
no per-station management queue to send the response on and it must be
sent on the probe response queue. The code should therefore not warn.
In theory, we could check and warn if the status code is success, but
that seems excessive, so just relax the check to allow any association
response frames.

If the first frame on a given TID is received with seqno 0 and needed
to be retransmitted, we erroneously drop it because the deduplication
data is initialized to zero, and then comparing
if (unlikely(ieee80211_has_retry(hdr->frame_control) &&
dup_data->last_seq[tid] == hdr->seq_ctrl &&
dup_data->last_sub_frame[tid] >= sub_frame_idx))
return true;
will return in iwl_mvm_is_dup() since last_sub_frame is also set to
zero, and sub_frame_idx is usually zero since this only covers the
relatively rare case of A-MSDU.
Fix this by initializing the last_seq array to 0xffff, which is an
impossible value for hdr->seq_ctrl to have here because the lower
four bits are the fragment number, and fragments aren't handled in
this code but go to mac80211 instead.

In commit b93b1fe3b532 ("iwlwifi: mvm: fix init_dbg flow to work
as expected"), the code was changed to make the stop conditional
on not having failed (and on not having init_dbg), which doesn't
make sense - we should stop the device regardless of failures.
Failure to do so is leading to the device being enabled when it
shouldn't be, and - if it gets re-enabled later - the new context
info code gets confused as paging data wasn't freed.
Remove the invalid error condition again.

This appears to happen in some cases, like when iwlmvm is unloaded and
loaded again without also unloading iwlwifi. Warn in this case and free
the paging data to be able to continue without causing corruption and
kernel crashes due to it (otherwise, paging data is overwritten, but
dram->paging_cnt gets to be twice as big as it should be, and then an
eventual free will crash.)

Wen reports significant memory leaks with DIF and O_DIRECT:
"With nvme devive + T10 enabled, On a system it has 256GB and started
logging /proc/meminfo & /proc/slabinfo for every minute and in an hour
it increased by 15968128 kB or ~15+GB.. Approximately 256 MB / minute
leaking.

SUnreclaim: 22720256 kB
When testcases with T10 enabled call into __blkdev_direct_IO_simple,
code doesn't free memory allocated by bio_integrity_alloc. The patch
fixes the issue. HTX has been run with +60 hours without failure."
Since __blkdev_direct_IO_simple() allocates the bio on the stack, it
doesn't go through the regular bio free. This means that any ancillary
data allocated with the bio through the stack is not freed. Hence, we
can leak the integrity data associated with the bio, if the device is
using DIF/DIX.
Fix this by providing a bio_uninit() and export it, so that we can use
it to free this data. Note that this is a minimal fix for this issue.
Any current user of bio's that are allocated outside of
bio_alloc_bioset() suffers from this issue, most notably some drivers.
We will fix those in a more comprehensive patch for 4.13. This also
means that the commit marked as being fixed by this isn't the real
culprit, it's just the most obvious one out there.
