net/tls: fix state removal with feature flags off
TLS offload drivers shouldn't (and currently don't) block
the TLS offload feature changes based on whether there are
active offloaded connections or not.
This seems to be a good idea, because we want the admin to
be able to disable the TLS offload at any time, and there
is no clean way of disabling it for active connections
(TX side is quite problematic). So if features are cleared
existing connections will stay offloaded until they close,
and new connections will not attempt offload to a given
device.
However, the offload state removal handling is currently
broken if feature flags get cleared while there are
active TLS offloads.
RX side will completely bail from cleanup, even on normal
remove path, leaving device state dangling, potentially
causing issues when the 5-tuple is reused. It will also
fail to release the netdev reference.
Remove the RX-side warning message, in next release cycle
it should be printed when features are disabled, rather
than when connection dies, but for that we need a more
efficient method of finding connection of a given netdev
(a'la BPF offload code).

net/tls: avoid NULL-deref on resync during device removal
When netdev with active kTLS sockets in unregistered
notifier callback walks the offloaded sockets and
cleans up offload state. RX data may still be processed,
however, and if resync was requested prior to device
removal we would hit a NULL pointer dereference on
ctx->netdev use.
Make sure resync is under the device offload lock
and NULL-check the netdev pointer.
This should be safe, because the pointer is set to
NULL either in the netdev notifier (under said lock)
or when socket is completely dead and no resync can
happen.
The other access to ctx->netdev in tls_validate_xmit_skb()
does not dereference the pointer, it just checks it against
other device pointer, so it should be pretty safe (perhaps
we can add a READ_ONCE/WRITE_ONCE there, if paranoid).

ocelot: Dont allocate another multicast list, use __dev_mc_sync
Doing kmalloc in atomic context is always an issue,
more so for a list that can grow significantly.
Turns out that the driver only uses the duplicated
list of multicast mac addresses to keep track of
what addresses to delete from h/w before committing
the new list from kernel to h/w back again via set_rx_mode,
every time this list gets updated by the kernel.
Given that the h/w knows how to add and delete mac addresses
based on the mac address value alone, __dev_mc_sync should be
the much better choice of kernel API for these operations
avoiding the considerable overhead of maintaining a duplicated
list in the driver.

gfs2: Fix sign extension bug in gfs2_update_stats
Commit
4d207133e9c3 changed the types of the statistic values in struct
gfs2_lkstats from s64 to u64. Because of that, what should be a signed
value in gfs2_update_stats turned into an unsigned value. When shifted
right, we end up with a large positive value instead of a small negative
value, which results in an incorrect variance estimate.

Commit
61697a6abd24 ("dm: eliminate 'split_discard_bios' flag from DM
target interface") incorrectly removed code from
__send_changing_extent_only() that is required to impose a per-target IO
boundary on IO that exceeds max_io_len_target_boundary(). Otherwise
"special" IO (e.g. DISCARD, WRITE SAME, WRITE ZEROES) can write beyond
where allowed.

The crash happens roughly 125..130ms after the disconnect. This
correlates with the 'delay' timer that is started on certain USB tx/rx
errors in the URB completion handler.
The problem is a race of usbnet_stop() with usbnet_start_xmit(). In
usbnet_stop() we call usbnet_terminate_urbs() to cancel all URBs in
flight. This only makes sense if no new URBs are submitted
concurrently, though. But the usbnet_start_xmit() can run at the same
time on another CPU which almost unconditionally submits an URB. The
error callback of the new URB will then schedule the timer after it was
already stopped.
The fix adds a check if the tx queue is stopped after the tx list lock
has been taken. This should reliably prevent the submission of new URBs
while usbnet_terminate_urbs() does its job. The same thing is done on
the rx side even though it might be safe due to other flags that are
checked there.

usbnet: ipheth: fix racing condition
Fix a racing condition in ipheth.c that can lead to slow performance.
Bug: In ipheth_tx(), netif_wake_queue() may be called on the callback
ipheth_sndbulk_callback(), _before_ netif_stop_queue() is called.
When this happens, the queue is stopped longer than it needs to be,
thus reducing network performance.
Fix: Move netif_stop_queue() in front of usb_submit_urb(). Now the order
is always correct. In case, usb_submit_urb() fails, the queue is woken up
again as callback will not fire.
Testing: This racing condition is usually not noticeable, as it has to
occur very frequently to slowdown the network. The callback from the USB
is usually triggered slow enough, so the situation does not appear.
However, on a Ubuntu Linux on VMWare Workstation, running on Windows 10,
the we loose the race quite often and the following speedup can be noticed:

Pull SPDX update from Greg KH:
"Here is a series of patches that add SPDX tags to different kernel
files, based on two different things:
- SPDX entries are added to a bunch of files that we missed a year
ago that do not have any license information at all.
These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the
last big sweep, or they were Makefile/Kconfig files, which we
didn't touch last time.
- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get
rid of all of these.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers.
The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.
There will be more series of these types of patches coming over the
next few weeks as the tools and reviewers crunch through the more
"odd" variants of how to say "GPLv2" that developers have come up with
over the years, combined with other fun oddities (GPL + a BSD
disclaimer?) that are being unearthed, with the goal for the whole
kernel to be cleaned up.
These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches"

QRTR packets has a message type in the header, which is repeated in the

For non-control messages an endianness fix introduced in v5.2-rc1 caused the
type to be 0, rather than QRTR_TYPE_DATA, causing all messages to be dropped by
the receiver. Fix this by converting and using qrtr_type, which will remain

tipc: Avoid copying bytes beyond the supplied data
TLV_SET is called with a data pointer and a len parameter that tells us
how many bytes are pointed to by data. When invoking memcpy() we need
to careful to only copy len bytes.
Previously we would copy TLV_LENGTH(len) bytes which would copy an extra
4 bytes past the end of the data pointer which newer GCC versions
complain about.
In file included from test.c:17:
In function 'TLV_SET',
inlined from 'test' at test.c:186:5:
/usr/include/linux/tipc_config.h:317:3:

We still want to ensure any padding bytes at the end are initialised, do
this with a explicit memset() rather than copy bytes past the end of
data. Apply the same logic to TCM_SET.

kbuild: do not check name uniqueness of builtin modules
I just thought it was a good idea to scan builtin.modules in the name
uniqueness checking, but a couple of false positives were found.
Stephen reported a false positive for ppc64_defconfig:
warning: same basename if the following are built as modules:
arch/powerpc/platforms/powermac/nvram.ko
drivers/char/nvram.ko
The former is never built as a module as you see in
arch/powerpc/platforms/powermac/Makefile:
# CONFIG_NVRAM is an arch. independent tristate symbol, for pmac32 we really
# need this to be a bool. Cheat here and pretend CONFIG_NVRAM=m is really
# CONFIG_NVRAM=y
obj-$(CONFIG_NVRAM:m=y) += nvram.o
Another example of false positive is arm64 defconfig:
warning: same basename if the following are built as modules:
arch/arm64/lib/crc32.ko
lib/crc32.ko
It is true CONFIG_CRC32 is a tristate option but it is always 'y' since
it is select'ed by ARM64. Hence, neither of them is built as a module
for the arm64 build.
From the above, modules.builtin essentially contains false positives.
I do not think it is a big deal as far as kmod is concerned, but false
positive warnings in the kernel build make people upset. It is better
to not check it.
Even without builtin.modules checked, we have enough (and more solid)
test coverage with allmodconfig.
While I touched this part, I replaced the sed code with neater one
provided by Stephen.

of_net: fix of_get_mac_address retval if compiled without CONFIG_OF
of_get_mac_address prior to commit
d01f449c008a ("of_net: add NVMEM
support to of_get_mac_address") could return only valid pointer or NULL,
after this change it could return only valid pointer or ERR_PTR encoded
error value, but I've forget to change the return value of
of_get_mac_address in case where the kernel is compiled without
CONFIG_OF, so I'm doing so now.

net: fix kernel-doc warnings for socket.c
Fix kernel-doc warnings by moving the kernel-doc notation to be
immediately above the functions that it describes.
Fixes these warnings for sock_sendmsg() and sock_recvmsg():

net: Treat sock->sk_drops as an unsigned int when printing
Currently, procfs socket stats format sk_drops as a signed int (%d). For large
values this will cause a negative number to be printed.
We know the drop count can never be a negative so change the format specifier to
%u.
