2015-07-14staging: unisys: fix random hangs with network stress in visornicTim Sell
We learned that it was possible for the core networking code to call visornic_xmit() within ISR context, resulting in the need for us to use spin_lock_irqsave() / spin_lock_irqrestore() to lock accesses to our virtual device channels. Without the correct locking added in this patch, random hangs would occur on typical kernels while stressing the netork. When using a kernel with CONFIG_DEBUG_SPINLOCK=y, a stackdump would occur at the time of the hang reporting: BUG: spinlock recursion on CPU#0, vnic_incoming/<pid> (see below for more details) We considered the possibility of adding a protocol between a visordriver and visorbus where the visordriver could specify which type of locking it required for its virtual device channels (essentially indicating whether or not it was possible for the channel to be accessed in ISR context), but decided this extra complexity was NOT needed, and that channel queues should always be accessed with the most-stringent locking. So that is what is implemented in this commit. Below is an example stackdump illustrating the spinlock recursion that is fixed by this commit. Note that we are first in virtnic_rx() writing to the device channel when an APIC timer interrupt occurs. Within the core networking code, net_rx_action() calls process_backlog(), which eventually lands up back up in virtnic_xmit() in the code attempting to also write to the device channel.

2015-07-14staging: unisys: fix random memory corruption in visorchannel_write()Tim Sell
visorchannel_write() and it's user visorbus_write_channel() are exported, so all visorbus function drivers (i.e., drivers that call visorbus_register_visor_driver()) are potentially affected by the bug. Because of pointer-arithmetic rules, the address being written to in the affected code was actually at byte offset: sizeof(struct channel_header) * offset instead of just <offset> bytes as intended. The bug could cause some very difficult-to-diagnose symptoms. The particular problem that led me on this chase was a kernel fault that would occur during 'insmod visornic' after a previous 'rmmod visornic', where we would fault during netdev_register_kobject() within pm_runtime_set_memalloc_noio() while traversing a device list, which occurred because dev->parent for the visorbus device had become corrupted. Fixes: 0abb60c1c ('staging: unisys: visorchannel_write(): Handle...')

I'm not sure what adverse runtime effects the previously-omitted NULL-termination would cause, but the code was definitely wrong.
