therefore, accept->peer = NULL will not be set when the client release

client->peer(accept->peer->peer) = NULL will cause used after free

This has been broken at some point. Just fix it by copying the can frame and
the cmsg data into IOB, and fix devif_poll to copy out the full data.
The can drivers expect to find the timeout timestamp in the end of the frame.

reason:
We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.
up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.
up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.

The argument addr is a pointer to a sockaddr structure.
This structure is filled in with the address of the peer socket,

Summary:
Implementation in accept4 is special, the requested newsock is saved as filep->priv. This will cause sock_file_close to use fs_heap_free filep->priv during close. When fs_heap is configured, the released memory will not be on fs_heap, causing a crash.

If arp search fails once, subsequent searches for the ip will directly
return failure, and sends an asynchronous arp request to try to update
arp table in the future. In this way, the psock_sendmsg interface will
not block for a long time each time because arp cannot be obtained.
This scenario is triggered when a udp socket frequently attempts to
access an ip address that does not exist on the LAN.

Summary:
The conn->keeptimer units is decisecond，but its unit is treated as
half-second in the tcp_timer & tcp_get_timeout function.
Therefore conn>keeptimer needs to be divided by 5(DSEC_PER_HSEC)
to match half-second units.
