staging: next: configfs: fix release link

2020-01-24T09:08:41+00:00

The functions link_destroy and link_release are both deleting list items.
link_release, however, does not check whether a certain link has already
been deleted from the list by function link_destroy. By fixing this
this patch prevents a kernel crash when removing the configuration
directory of a link that already has been destroyed.

staging: most: core: remove container struct

2020-01-24T09:08:40+00:00

This patch declares and initializes the bus, bus driver and the
component list without a container struct, as it introduces an
unnecessary level of abstraction.

This patch removes the device from the MOST core driver and uses the
device from the adapter driver.

staging: most: remove device from interface structure

2020-01-24T09:08:39+00:00

This patch makes the adapter drivers use their own device structures
when registering a most interface with the core module.
With this the module that actually operates the physical device is the
owner of the device.

staging: most: net: fix buffer overflow

2020-01-22T08:51:15+00:00

If the length of the socket buffer is 0xFFFFFFFF (max size for an
unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14
(ETH_HLEN).  Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN)
which overflows and results in a value of 2.  These values for
payload_len and mdp_len will pass current buffer size checks.

This patch checks if derived from skb->len sum may overflow.

The check is based on the following idea:

For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`,
`V1 + V2` overflows iif `SUM < V1`.

staging: most: remove header include path to drivers/staging

2020-01-16T19:56:31+00:00

There is no need to add "ccflags-y += -I $(srctree)/drivers/staging"
just for including .

Use the #include "..." directive with the correct relative path.
