Christophe JAILLET 6afd112c3f net: ieee802154: adf7242: Fix some potential buffer overflow in adf7242_stats_show()
[ Upstream commit ca082f019d ]

strncat() usage in adf7242_debugfs_init() is wrong.
The size given to strncat() is the maximum number of bytes that can be
written, excluding the trailing NULL.

Here, the size that is passed, DNAME_INLINE_LEN, does not take into account
the size of "adf7242-" that is already in the array.

In order to fix it, use snprintf() instead.

Dinghao Liu 84c6aa0ae5 ieee802154: ca8210: Fix a potential UAF in ca8210_probe
[ Upstream commit f990874b1c ]

If of_clk_add_provider() fails in ca8210_register_ext_clock(),
it calls clk_unregister() to release priv->clk and returns an
error. However, the caller ca8210_probe() then calls ca8210_remove(),
where priv->clk is freed again in ca8210_unregister_ext_clock(). In
this case, a use-after-free may happen in the second time we call
clk_unregister().

Fix this by removing the first clk_unregister(). Also, priv->clk could
be an error code on failure of clk_register_fixed_rate(). Use
IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().

Harshit Mogalapalli e38b0ab9db ca8210: Fix unsigned mac_len comparison with zero in ca8210_skb_tx()
[ Upstream commit 748b2f5e82 ]

mac_len is of type unsigned, which can never be less than zero.

	mac_len = ieee802154_hdr_peek_addrs(skb, &header);
	if (mac_len < 0)
		return mac_len;

Change this to type int as ieee802154_hdr_peek_addrs() can return negative
integers, this is found by static analysis with smatch.

Hauke Mehrtens 246bcd05ba ca8210: Fix crash by zero initializing data
[ Upstream commit 1e24c54da2 ]

The struct cas_control embeds multiple generic SPI structures and we
have to make sure these structures are initialized to default values.
This driver does not set all attributes. When using kmalloc before some
attributes were not initialized and contained random data which caused
random crashes at bootup.

Lin Ma 9f8558c5c6 ieee802154/adf7242: defer destroy_workqueue call
[ Upstream commit afe7116f6d ]

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 3e0588c291 ("hamradio: defer
ax25 kfree after unregister_netdev") which let the
ieee802154_unregister_hw() to handle the synchronization. This patch
takes the second option.

Miquel Raynal 23b2a25382 net: ieee802154: at86rf230: Stop leaking skb's
[ Upstream commit e5ce576d45 ]

Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. In the Tx case we then leak
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
area and the issue kind of always existed.

Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("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/'

Sergiu Cuciurean 5b5c328f63 net: ieee802154: ca8210: Use new structure for SPI transfer delays
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).

__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
