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 902c098a3663 ("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 902c098a3663.

* | drivers/char/random.c: fix priming of last_dataJarod Wilson2013-05-241-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ec8f02da9ea5 ("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.

I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."
