Fixes a crash in poll() when an AF_XDP socket is opened in copy mode
and the bound device does not have ndo_xsk_wakeup defined. Avoid
trying to call the non-existing ndo and instead call the internal xsk

Isolate CAIF transport drivers into their own menu.
This cleans up the main Network device support menu,
makes it easier to find the CAIF drivers, and makes it
easier to enable/disable them as a group.

The most commonly called function in the driver is long due for a
rename. The "packed" word is redundant (it doesn't make sense to
transfer an unpacked structure, since that is in CPU endianness yadda
yadda), and the "spi" word is also redundant since argument 2 of the
function is SPI_READ or SPI_W
Having a function that takes a variable number of unpacked bytes which
it generically calls an "int" is confusing and makes auditing patches
next to impossible.
We only use spi_send_int with the int sizes of 32 and 64 bits. So just
make the spi_send_int function less generic and replace it with th
This series provides some mechanical cleanup patches related to function
names and prototypes.

The struct __dsa_skb_cb is supposed to span the entire 48-byte skb
control block, while the struct dsa_skb_cb only the portion of it which
is used by the DSA core (the rest is available as private data to

Otherwise, with CONFIG_DEBUG_SPINLOCK=y, this stack trace gets printed
when enabling RX timestamping and receiving a PTP frame:
[ 318.537078] INFO: trying to register non-static key.
[ 318.542040] the code is fine but needs lockdep annotation.
[ 318.547500] turning off the locking correctness v
Currently this stack trace can be seen with CONFIG_DEBUG_ATOMIC_SLEEP=y:
[ 41.568348] BUG: sleeping function called from invalid context at
kernel/locking/mutex.c:909
[ 41.576757] in_atomic(): 1, irqs_disabled(): 0, pid: 208, name: ptp4l
[ 41.583212] INFO: lockdep is turned off.
[ 41.5871
This series fixes the locking API usage problems spotted when compiling
the kernel with CONFIG_DEBUG_ATOMIC_SLEEP=y and CONFIG_DEBUG_SPINLOCK=y.

tcp_twsk_unique() has a hard coded assumption about ipv4 loopback
being 127/8
Lets instead use the standard ipv4_is_loopback() method,
in a new ipv6_addr_v4mapped_loopback() helper.

OK, let me try again from the start. Consider two values:

* The actual number of bytes in buffers in the current backlog list

The experimental root file system support in cifs.ko relies on
ipconfig to set up the network stack and then accessing the SMB share
that contains the rootfs files.

Hi,
This patch series enables Linux to mount root file systems over the
network by utilizing SMB protocol.
Upstream commit 8eecd1c2e5bc ("cifs: Add support for root file
systems") introduced a new CONFIG_CIFS_ROOT option, a virtual device
(Root_CIFS) and a kernel cmdline parameter "cifsroot=" whi
Add a new virtual device named /dev/cifs (0xfe) to tell the kernel to
mount the root file system over the network by using SMB protocol.
cifs_root_data() will be responsible to retrieve the parsed
information of the new command-line option (cifsroot=) and then call
do_mount_root() with the appropr
