We had historically not checked that genlmsghdr.reserved
is 0 on input which prevents us from using those precious
bytes in the future.
One use case would be to extend the cmd field, which is
currently just 8 bits wide and 256 is not a lot of commands
for some core families.
To make sure that new families do the right thing by default
put the onus of opting out of validation on existing families.

There is a possible race condition (use-after-free) like below
(FREE) | (USE)
adf7242_remove | adf7242_channel
cancel_delayed_work_sync |
destroy_workqueue (1) | adf7242_cmd_rx
| mod_delayed_work (2)
|
The root cause for this race is that the upper layer (ieee802154) is
unaware of this detaching event and the function adf7242_channel can
be called without any checks.
To fix this, we can add a flag write at the beginning of adf7242_remove
and add flag check in adf7242_channel. Or we can just defer the
destructive operation like other commit 3e0588c291d6 ("hamradio: defer
ax25 kfree after unregister_netdev") which let the
ieee802154_unregister_hw() to handle the synchronization. This patch
takes the second option.

====================
pull-request: ieee802154-next 2022-05-01
Miquel Raynal landed two patch series bundled in this pull request.
The first series re-works the symbol duration handling to better
accommodate the needs of the various phy layers in ieee802154.
In the second series Miquel improves th errors handling from drivers
up mac802154. THis streamlines the error handling throughout the
ieee/mac802154 stack in preparation for sync TX to be introduced for
MLME frames.

Commit 493bc90a9683 ("at86rf230: add debugfs support") brought trac
support as part of a debugfs feature, in order to add some testing
capabilities involving ack handling.
As we want to collect trac errors but do not need the debugfs feature
anymore, let's partially revert this commit, keeping the Tx trac
handling part which still makes sense. This allows to always return the
trac error directly to the core with the recently introduced
ieee802154_xmit_error() helper.

If we end up at this location, it means that there was likely a hardware
issue (either a bus error when asynchronously offloading the packet to
the transceiver, or the transceiver took too long for some state
change). In this case it was decided to return IEEE802154_SYSTEM_ERROR
through the ieee802154_xmit_hw_error() helper dedicated to non
IEEE802.15.4 specific errors.
Let's use this helper instead of (almost) open-coding it.

Tdsym is often given in the spec as pretty small numbers in microseconds
and hence was reflected in the code as symbol_duration and was stored as
a u8. Actually, for UWB PHYs, the symbol duration is given in
nanoseconds and are as precise as picoseconds. In order to handle better
these PHYs, change the type of symbol_duration to u32 and store this
value in nanoseconds.
All the users of this variable are updated in a mechanical way.

problems as well as making use of the modern api without kmalloc() needs in he
driver.
Miquel Raynal landed some changes to ensure proper frame checksum checking with

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

the skb structure.
Free the skb structure upon error before returning when appropriate.
As the 'is_tx = 0' cannot be moved in the complete handler because of a
possible race between the delay in switching to STATE_RX_AACK_ON and a
new interrupt, we introduce an intermediate 'was_tx' boolean just for
this purpose.
There is no Fixes tag applying here, many changes have been made on this

Old USB API is prone to uninit value bugs if error handling is not
correct. Let's move atusb to use new USB API to
1) Make code more simple, since new API does not require memory
to be allocates via kmalloc()
2) Defend driver from usb-related uninit value bugs.
3) Make code more modern and simple
This patch removes atusb usb wrappers as Greg suggested [0], this will make
code more obvious and easier to understand over time, and replaces old
API calls with new ones.
Also this patch adds and updates usb related error handling to prevent
possible uninit value bugs in future

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.
The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

`spi_transfer` + spi_transfer_delay_exec()")

Adjust indentation from spaces to tab (+optional two spaces) as in

An update from ieee802154 for *net-next*
I waited until last minute to see if there are more patches coming in.
Seems not and we will only have one change for ieee802154 this time.
Yue Haibing removed an unused variable in the cc2520 driver.

====================
pull-request: ieee802154 for net 2019-09-28
An update from ieee802154 for your *net* tree.
Three driver fixes. Navid Emamdoost fixed a memory leak on an error
path in the ca8210 driver, Johan Hovold fixed a use-after-free found
by syzbot in the atusb driver and Christophe JAILLET makes sure
__skb_put_data is used instead of memcpy in the mcr20a driver
I switched from branches to tags here to be pulled from. So far not
annotated and not signed. Once I fixed my scripts it should contain
this messages as annotations. If you want it signed as well just tell
me. If there are any problems let me know.
