Subject: [PATCH] virtio-9p: use accessor to get thread_pool
|
||||
|
||||
The aio_context_new() function does not allocate a thread pool. This is
|
||||
deferred to the first call to the aio_get_thread_pool() accessor. It is
|
||||
hence forbidden to access the thread_pool field directly, as it may be
|
||||
NULL. The accessor *must* be used always.
|
||||

Subject: [PATCH] net: ne2000: check ring buffer control registers
|
||||
|
||||
Ne2000 NIC uses ring buffer of NE2000_MEM_SIZE(49152)
|
||||
bytes to process network packets. Registers PSTART & PSTOP
|
||||
define ring buffer size & location. Setting these registers
|
||||
to invalid values could lead to infinite loop or OOB r/w
|
||||
access issues. Add check to avoid it.
