Add support for OMAP4 version of TRNG module that is present on OMAP4, AM33xx and OMAP5 SoCs. The modules have several differences including register offsets, output size, triggering rng and how configuring FROs. To handle these differences, a platform_data structure is defined and contains routine pointers, register offsets. OMAP2 specific routines are prefixed with 'omap2_' and OMAP4 specific routines are prefixed with 'omap4_'. Note: Few Hard coded values are from the TI AM33xx SDK.

/dev/oldmem provides the interface for us to access the "old memory" in the dump-capture kernel. Unfortunately, no one actually uses this interface. And this interface could actually cause some real problems if used on ia64 where the cached/uncached accesses are mixed. See the discussion from the link: https://lkml.org/lkml/2013/4/12/386. So Eric suggested that we should remove /dev/oldmem as an unused piece of code. [akpm@linux-foundation.org: mention /dev/oldmem obsolescence in devices.txt] Suggested-by: N"Eric W.

由 Thomas Petazzoni 提交于
In fa1f68db ("drivers: misc: pass miscdevice pointer via file private data"), the misc driver infrastructure was changed to assigned file->private_data as a pointer to the 'struct miscdevice' that corresponds to the device being opened. However, this assignment was only done when the misc driver was declaring a driver-specific ->open() operation in its file_operations. This doesn't make sense, as the driver may not necessarily have a custom ->open() operation, and might still be interested in having file->private_data properly set for use in its ->read() and write() operations. Therefore, we move the assignment of file->private_data outside of the condition that tests whether a driver-specific ->open() operation was defined.

Commit 902c098a ("random: use lockless techniques in the interrupt path") turned IRQ path from being spinlock protected into lockless cmpxchg-retry update. That commit removed r->lock serialization between crediting entropy bits from IRQ context and accounting when extracting entropy on userspace read path, but didn't turn the r->entropy_count reads/updates in account() to use cmpxchg as well. It has been observed, that under certain circumstances this leads to read() on /dev/urandom to return 0 (EOF), as r->entropy_count gets corrupted and becomes negative, which in turn results in propagating 0 all the way from account() to the actual read() call. Convert the accounting code to be the proper lockless counterpart of what has been partially done by 902c098a.

Commit ec8f02da ("random: prime last_data value per fips requirements") added priming of last_data per fips requirements. Unfortuantely, it did so in a way that can lead to multiple threads all incrementing nbytes, but only one actually doing anything with the extra data, which leads to some fun random corruption and panics. The fix is to simply do everything needed to prime last_data in a single shot, so there's no window for multiple cpus to increment nbytes -- in fact, we won't even increment or decrement nbytes anymore, we'll just extract the needed EXTRACT_SIZE one time per pool and then carry on with the normal routine. All these changes have been tested across multiple hosts and architectures where panics were previously encoutered. The code changes are are strictly limited to areas only touched when when booted in fips mode. This change should also go into 3.8-stable, to make the myriads of fips users on 3.8.x happy.

The patch fixes a problem in the lp driver that can cause oopses as follows: process A: calls lp_write, which in turn calls parport_ieee1284_write_compat, and that invokes parport_wait_peripheral process B: meanwhile does an ioctl(LPGETSTATUS), which call lp_release_parport when done. This function will set physport->cad = NULL. process A: parport_wait_peripheral tries to dereference physport->cad and dies So, protect that code with the port_mutex in order to protect against simultaneous calls to lp_read/lp_write. Similar protection is probably required for ioctl(LPRESET)... This patch was done by IBM a while back and we (at suse) have that since at least 2004 in our repos. Let's make it upstream.
