netdev_alloc_skb() is used by networks driver in their RX path to
allocate an skb to receive an incoming frame.
With recent skb->head_frag infrastructure, it makes sense to change
netdev_alloc_skb() to use build_skb() and a frag allocator.
This permits a zero copy splice(socket->pipe), and better GRO or TCP

Change the name of prepare_connect_authorizer(). The next
patch is going to make this function no longer add anything to the
connection's out_kvec, so it will no longer fit the pattern of

In addition, pass the address of a variable that will hold the

prepare_write_connect() prepares a connect message, then sets
WRITE_PENDING on the connection. Then *after* this, it calls
prepare_connect_authorizer(), which updates the content of the
connection buffer already queued for sending. It's also possible it
will result in prepare_write_connect() returning -EAGAIN despite the
WRITE_PENDING big getting set.
Fix this by preparing the connect authorizer first, setting the

As the comment for l2cap_get_chan_by_scid indicated, the function used
to return a locked socket. The lock for the socket was acquired while
the channel list was also locked.
When locking was moved over to the l2cap_chan structure, the channel
lock was no longer acquired with the channel list still locked. This
made it possible for the l2cap_chan to be deleted after
conn->chan_lock was released but before l2cap_chan_lock was called.
Making the call to l2cap_chan_lock before releasing conn->chan_lock
makes it impossible for the l2cap_chan to be deleted at the wrong

The L2CAP MTU for incoming data is verified differently depending on
the L2CAP mode, so the check is best performed in a mode-specific
context. Checking the incoming MTU before HCI fragment reassembly is
a layer violation and assumes all bytes after the standard L2CAP
header are L2CAP data.
This approach causes issues with unsegmented ERTM or streaming mode
frames, where there are additional enhanced or extended headers before
the data payload and possible FCS bytes after the data payload. A
valid frame could be as many as 10 bytes larger than the MTU.
Removing this code is the best fix, because the MTU is checked later
on for all L2CAP data frames (connectionless, basic, ERTM, and
streaming). This also gets rid of outdated locking (socket instead of
l2cap_chan) and an extra lookup of the channel ID.

nfc_llcp_general_bytes is defined in nfc/core.c as:
nfc_llcp_general_bytes(struct nfc_dev *dev, size_t *gb_len).
as in nfc/nfc.h:
nfc_llcp_general_bytes(struct nfc_dev *dev, u8 *gb_len), if CONFIG_NFC_LLCP
is not defined.
so we got some warnings,
net/nfc/core.c:207:2: warning: passing argument 2 of ‘nfc_llcp_general_bytes’ from incompatible pointer type [enabled by default]
net/nfc/nfc.h:87:19: note: expected ‘u8 *’ but argument is of type ‘size_t *’

It is now specified that nfc_target_found() and nfc_target_lost() core
functions must not be called from an atomic context. This allow us to
serialize calls and protect the targets table using the nfc device lock
instead of a spinlock.

The NFC Core now caches the active nfc target pointer, thereby avoiding
the need to lookup the target table for each invocation of a driver ops.
Consequently, pn533, HCI and NCI now directly receive an nfc_target
pointer instead of a target index.

The SHDLC link layer of HCI based drivers uses CRC-CCITT and thus
needs to select that kernel option.
Otherwise it ends up with this linking error:
