2011-06-15drivers/char/hpet.c: fix periodic-emulation for delayed interruptsNils Carlson
When interrupts are delayed due to interrupt masking or due to other interrupts being serviced the HPET periodic-emuation would fail. This happened because given an interval t and a time for the current interrupt m we would compute the next time as t + m. This works until we are delayed for > t, in which case we would be writing a new value which is in fact in the past. This can be solved by computing the next time instead as (k * t) + m where k is large enough to be in the future. The exact computation of k is described in a comment to the code. More detail: Assuming an interval of 5 between each expected interrupt we have a normal case of t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t5: interrupt, read t5 from comparator, set next interrupt t5 + 5 t10: interrupt, read t10 from comparator, set next interrupt t10 + 5 ... So, what happens when the interrupt is serviced too late? t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t11: delayed interrupt serviced, read t5 from comparator, set next interrupt t5 + 5, which is in the past! ... counter loops ... t10: Much much later, get the next interrupt. This can happen either because we have interrupts masked for too long (some stupid driver goes on a printk rampage) or just because we are pushing the limits of the interval (too small a period), or both most probably. My solution is to read the main counter as well and set the next interrupt to occur at the right interval, for example: t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t11: delayed interrupt serviced, read t5 from comparator, set next interrupt t15 as t10 has been missed. t15: back on track.

2011-05-26drivers/char/ppdev.c: put gotten port valueJulia Lawall
parport_find_number() calls parport_get_port() on its result, so there should be a corresponding call to parport_put_port() before dropping the reference. Similar code is found in the function register_device() in the same file. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression struct parport * x; expression ra,rr; statement S1,S2; @@ x = parport_find_number(...) ... when != x = rr when any when != parport_put_port(x,...) when != if (...) { ... parport_put_port(x,...) ...} ( if(<+...x...+>) S1 else S2 | if(...) { ... when != x = ra when forall when != parport_put_port(x,...) *return...; } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-05-23apm-emulation: apm_mutex breaks ACK; remove itPaul Parsons
apm_mutex is locked by a process (e.g. apm -s) at the start of apm_ioctl() and remains locked while pm_suspend() is called. Any subsequent process trying to ACK the suspend (e.g. apmd) is then blocked at the start of apm_ioctl(), causing the suspend to be delayed for 5 seconds in apm_suspend_notifier() while the ACK times out. In short, ACKs don't work. The driver's data structures are sufficiently protected by assorted locks. And pm_suspend() has its own mutex to prevent reentrancy. Consequently there is no obvious requirement for apm_mutex, which evolved from earlier BKL calls. So let's remove it. Signed-off-by: Paul Parsons <lost.distance@yahoo.com> Acked-by: Rafael J.

2011-05-18drivercore: revert addition of of_match to struct deviceGrant Likely
Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

This call was disabled as hot-unplugging one virtconsole port led to another virtconsole port freezing. Upon testing it again, this now works, so enable it. In addition, a bug was found in qemu wherein removing a port of one type caused the guest output from another port to stop working. I doubt it was just this bug that caused it (since disabling the hvc_remove() call did allow other ports to continue working), but since it's all solved now, we're fine with hot-unplugging of virtconsole ports.

As said in the comment, (pg_start + mem->page_count) may wrap in case of AGPIOC_BIND, and it is not checked at all in case of AGPIOC_UNBIND.

2011-04-21agp: fix OOM and buffer overflowVasiliy Kulikov
page_count is copied from userspace. agp_allocate_memory() tries to check whether this number is too big, but doesn't take into account the wrap case. Also agp_create_user_memory() doesn't check whether alloc_size is calculated from num_agp_pages variable without overflow. This may lead to allocation of too small buffer with following buffer overflow. Another problem in agp code is not addressed in the patch - kernel memory exhaustion (AGPIOC_RESERVE and AGPIOC_ALLOCATE ioctls). It is not checked whether requested pid is a pid of the caller (no check in agpioc_reserve_wrap()). Each allocation is limited to 16KB, though, there is no per-process limit. This might lead to OOM situation, which is not even solved in case of the caller death by OOM killer - the memory is allocated for another (faked) process.

This patch fixes an issue in OpenIPMI module where sometimes an ABORT command is sent after sending an IPMI request to BMC causing the IPMI request to fail.

2011-03-06virtio: console: Don't access vqs if device was unpluggedAmit Shah
If a virtio-console device gets unplugged while a port is open, a subsequent close() call on the port accesses vqs to free up buffers. This can lead to a crash. The buffers are already freed up as a result of the call to unplug_ports() from virtcons_remove(). The fix is to simply not access vq information if port->portdev is NULL.

2011-03-01Revert "TPM: Long default timeout fix"Linus Torvalds
This reverts commit c4ff4b829ef9e6353c0b133b7adb564a68054979. Ted Ts'o reports: "TPM is working for me so I can log into employer's network in 2.6.37. It broke when I tried 2.6.38-rc6, with the following relevant lines from my dmesg: [ 11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78) [ 25.734114] tpm_tis 00:0b: Operation Timed out [ 78.040949] tpm_tis 00:0b: Operation Timed out This caused me to get suspicious, especially since the _other_ TPM commit in 2.6.38 had already been reverted, so I tried reverting commit c4ff4b829e: "TPM: Long default timeout fix". With this commit reverted, my TPM on my Lenovo T410 is once again working."
