bhash2 added a new member sk_bind2_node in struct sock to link
sockets to bhash2 in addition to bhash.
bhash is still needed to search conflicting sockets efficiently
from a port for the wildcard address. However, bhash itself need
not have sockets.
If we link each bhash2 bucket to the corresponding bhash bucket,
we can iterate the same set of the sockets from bhash2 via bhash.
This patch links bhash2 to bhash only, and the actual use will be
in the later patches. Finally, we will remove sk_bind2_node.

Later, we no longer link sockets to bhash. Instead, each bhash2
bucket is linked to the corresponding bhash bucket.
Then, we pass the bhash bucket to bhash2 allocation functions as
tb. However, tb is already used in inet_bind2_bucket_create() and
inet_bind2_bucket_init() as the bhash2 bucket.
To make the following diff clear, let's use tb2 for the bhash2 bucket
there.

inet_bind2_bucket_addr_match() and inet_bind2_bucket_match_addr_any()
are called for each bhash2 bucket to check conflicts. Thus, we call
ipv6_addr_any() and ipv6_addr_v4mapped() over and over during bind().
Let's avoid calling them by saving the address type in inet_bind2_bucket.

In bhash2, IPv4/IPv6 addresses are saved in two union members,
which complicate address checks in inet_bind2_bucket_addr_match()
and inet_bind2_bucket_match_addr_any() considering uninitialised
memory and v4-mapped-v6 conflicts.
Let's simplify that by saving IPv4 address as v4-mapped-v6 address
and defining tb2.rcv_saddr as tb2.v6_rcv_saddr.s6_addr32[3].
Then, we can compare v6 address as is, and after checking v4-mapped-v6,
we can compare v4 address easily. Also, we can remove tb2->family.
Note these functions will be further refactored in the next patch.

The protocol family tests in inet_bind2_bucket_addr_match() and
inet_bind2_bucket_match_addr_any() are ordered as follows.
if (sk->sk_family != tb2->family)
else if (sk->sk_family == AF_INET6)
else
This patch rearranges them so that AF_INET6 socket is handled first
to make the following patch tidy, where tb2->family will be removed.
if (sk->sk_family == AF_INET6)

While checking port availability in bind() or listen(), we used only
bhash for all v4-mapped-v6 addresses. But there is no good reason not
to use bhash2 for v4-mapped-v6 non-wildcard addresses.
Let's do it by returning true in inet_use_bhash2_on_bind(). Then, we
also need to add a test in inet_bind2_bucket_match_addr_any() so that
::ffff:X.X.X.X will match with 0.0.0.0.
Note that sk->sk_rcv_saddr is initialised for v4-mapped-v6 sk in
__inet6_bind().

In min_key_size_set():

return -EINVAL;
hci_dev_lock(hdev);
hdev->le_min_key_size = val;

In max_key_size_set():

hdev->le_max_key_size = val;

The atomicity violation occurs due to concurrent execution of set_min and
set_max funcs.Consider a scenario where setmin writes a new, valid 'min'
value, and concurrently, setmax writes a value that is greater than the
old 'min' but smaller than the new 'min'. In this case, setmax might check
against the old 'min' value (before acquiring the lock) but write its
value after the 'min' has been updated by setmin. This leads to a
situation where the 'max' value ends up being smaller than the 'min'
value, which is an inconsistency.
This possible bug is found by an experimental static analysis tool
developed by our team, BassCheck[1]. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations. The above
possible bug is reported when our tool analyzes the source code of
Linux 5.17.
To resolve this issue, it is suggested to encompass the validity checks
within the locked sections in both set_min and set_max funcs. The
modification ensures that the validation of 'val' against the
current min/max values is atomic, thus maintaining the integrity of the
settings. With this patch applied, our tool no longer reports the bug,
with the kernel configuration allyesconfig for x86_64. Due to the lack of
associated hardware, we cannot test the patch in runtime testing, and just
verify it according to the code logic.

Do not return a negative number in case of issue, just print an error
and return count. Before this change, in case of error, the returned
negative number was internally converted to 0 in ttyport_receive_buf,
now when the receive buffer is corrupted we return the size of the whole
received data (`count`). This should allow for better recovery in case
receiver/transmitter get out of sync if some data is lost.
This fixes a WARN in ttyport_receive_buf().

When a PA sync socket is closed, the associated hcon is also unlinked
and cleaned up. If there are no other hcons marked with the
HCI_CONN_PA_SYNC flag, HCI_OP_LE_PA_TERM_SYNC is sent to controller.
Between the time of the command and the moment PA sync is terminated
in controller, residual BIGInfo reports might continue to come.
This causes a new PA sync hcon to be added, and a new socket to be
notified to user space.
This commit fixs this by adding a flag on a Broadcast listening
socket to mark when the PA sync child has been closed.
This flag is checked when BIGInfo reports are indicated in
iso_connect_ind, to avoid recreating a hcon and socket if
residual reports arrive before PA sync is terminated.

For ISO Broadcast, all BISes from a BIG have the same lifespan - they
cannot be created or terminated independently from each other.
This links together all BIS hcons that are part of the same BIG, so all
hcons are kept alive as long as the BIG is active.
If multiple BIS sockets are opened for a BIG handle, and only part of
them are closed at some point, the associated hcons will be marked as
open. If new sockets will later be opened for the same BIG, they will
be reassociated with the open BIS hcons.
All BIS hcons will be cleaned up and the BIG will be terminated when
the last BIS socket is closed from userspace.

====================
intel: use bitfield operations
Jesse Brandeburg says:
After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET(). It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.
This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.
Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.
The second patch just adds all the new #includes in one go.
The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.
The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.

conntrack zones are heavily used by tools like openvswitch to run
multiple virtual "routers" on a single machine. In this context each
conntrack zone matches to a single router, thereby preventing
overlapping IPs from becoming issues.
In these systems it is common to operate on all conntrack entries of a
given zone, e.g. to delete them when a router is deleted. Previously this
required these tools to dump the full conntrack table and filter out the
relevant entries in userspace potentially causing performance issues.
To do this we reuse the existing CTA_ZONE attribute. This was previous
parsed but not used during dump and flush requests. Now if CTA_ZONE is
set we filter these operations based on the provided zone.
However this means that users that previously passed CTA_ZONE will
experience a difference in functionality.
Alternatively CTA_FILTER could have been used for the same
functionality. However it is not yet supported during flush requests and
is only available when using AF_INET or AF_INET6.

If a transaction is aborted, we should mark the to-be-released NEWSET dead,
just like commit path does for DEL and DESTROYSET commands.
In both cases all remaining elements will be released via
set->ops->destroy().
The existing abort code does NOT post the actual release to the work queue.
Also the entire __nf_tables_abort() function is wrapped in gc_seq
begin/end pair.
Therefore, async gc worker will never try to release the pending set
elements, as gc sequence is always stale.
It might be possible to speed up transaction aborts via work queue too,
this would result in a race and a possible use-after-free.
So fix this before it becomes an issue.

For now, this isn't allowed. The API to mac80211 isn't great
for this, but we need to change the API to move puncturing
into the chanctx/chandef, and will do it better then.

eSR is activated when a chanctx is assigned to more than one link.
During eSR activation we should disable RLC for both phys, and configure
the FW with a special phy command for both phys.
Currently we assign the phy_ctxt to the link only after eSR activation,
so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW.
Fix this by first assigning the new phy_ctxt to the link and then
doing the eSR activation.

The driver copies the userspace buffer into an internal NUL
byte terminated buffer. While doing so, it was reading beyond
the end of the userspace buffer, overwriting its own NUL
termination in the process.
Fix this by only copying the correct number of bytes.

It is possible that though multiple links are enabled we cannot enabled
EMLSR enable more than a single link, e.g., all valid links are on the
same band etc. Thus, do not warn in case no valid link pair is found.

Now with the mac80211 locking model changed, we no longer can
cause any bad dependencies here between mvm->mutex and other
mutexes in mac80211, so we no longer need to drop the mutex
early or even temporarily. Clean this up.

If we want to drop packets, that's surely a good thing to
do when we want to enter rfkill. Send this command despite
rfkill so we can successfully clean up everything, we need
to handle it separately since it has CMD_WANT_SKB, so it's
not going to automatically return success when in rfkill.

The NVM_CHANNEL_ACTIVE bit means that active scanning/beaconing is
allowed, however it's not an exact opposite of IEEE80211_CHAN_NO_IR.
For example, NVM_CHANNEL_ACTIVE bit is not set on DFS channels, while
cfg80211 doesn't really expect NO-IR on DFS channels.
