On s390 I have seen some random
"Warning: unable to open an initial console"
boot failure. Turns out that tty_open fails, because the
hvc_alloc was not yet done. In former times this could not happen,
since the probe function automatically called hvc_alloc. With newer
versions (multiport) some host<->guest interaction is required
before hvc_alloc is called. This might be too late, especially if
an initramfs is involved. Lets use a completion if we have
multiport and an early console.

This commit adds port-specific stats for the number of bytes received,
sent and discarded. They're exposed via the debugfs interface. This
data can be used to check for data loss bugs (or disprove such claims).
It can also be used for accounting, if there's such a need.
The stats remain valid throughout the lifetime of the port. Unplugging
a port will reset the stats. The numbers are not reset across port
opens/closes.

Instead of pulling in a buffer from the vq each time it's called,
get_inbuf() now checks if the current active buffer, in port->inbuf is
valid. If it is, just returns a pointer to it. This ends up
simplifying a lot of code calling get_inbuf() since the check for
port->inbuf being valid was done by all the callers.

We don't allow port name changes dynamically for a port. So any
requests by the host to change the name are ignored.
Before this patch, if the hypervisor sent a port name while we had one
set already, we would leak memory equivalent to the size of the old
name.
This scenario wasn't expected so far, but with the suspend-resume
support, we'll send the VIRTIO_CONSOLE_PORT_READY message after restore,
which can get us into this situation.

Just convert all the files that have an nmi handler to the new routines.
Most of it is straight forward conversion. A couple of places needed some
tweaking like kgdb which separates the debug notifier from the nmi handler
and mce removes a call to notify_die.
[Thanks to Ying for finding out the history behind that mce call
https://lkml.org/lkml/2010/5/27/114
And Boris responding that he would like to remove that call because of it
https://lkml.org/lkml/2011/9/21/163]
The things that get converted are the registeration/unregistration routines
and the nmi handler itself has its args changed along with code removal
to check which list it is on (most are on one NMI list except for kgdb
which has both an NMI routine and an NMI Unknown routine).

[The first hunk didn't make sense given one could expect
way less data than TPM_BUFSIZE, so added tpm_transmit boundary
check over bufsiz instead
The last parameter of tpm_transmit() reflects the amount
of data expected from the device, and not the buffer size
being supplied to it. It isn't ideal to parse it directly,
so we just set it to the maximum the input buffer can handle
and let the userspace API to do such job.]

vfork is moving away from freezer_[do_not_]count() one way or the
other leaving apm_ioctl() as the only user. apm_ioctl() just wants to
wait for suspend/resume cycle to complete without hindering the
freezer. Use wait_event_freezable() instead.
The only annoyance is that wait_event_freezable() wakes up with
-ERESTART if there are pending signals while apm_ioctl() wants to
ignore all signals until suspend is complete. We can play with
@current->[real_]blocked but this is hardly a performance or latency

Computers have become a lot faster since we compromised on the
partial MD4 hash which we use currently for performance reasons.
MD5 is a much safer choice, and is inline with both RFC1948 and
other ISS generators (OpenBSD, Solaris, etc.)
Furthermore, only having 24-bits of the sequence number be truly
unpredictable is a very serious limitation. So the periodic
regeneration and 8-bit counter have been removed. We compute and
use a full 32-bit sequence number.
For ipv6, DCCP was found to use a 32-bit truncated initial sequence
number (it needs 43-bits) and that is fixed here as well.

This patch introduces a function for automatic probing for the Intel iTPM
STS_DATA_EXPECT flaw.
The patch splits the current tpm_tis_send function into 2 parts where the 1st
part is now called tpm_tis_send_data() and merely sends the data to the TPM.
This function is then used for probing. The new tpm_tis_send function now
first calls tpm_tis_send_data and if that succeeds has the TPM process the
command and waits until the response is there.
The probing for the Intel iTPM is only invoked if the user has not passed
itpm=1 as parameter for the module *or* if such a TPM was detected via ACPI.
Previously it was necessary to pass itpm=1 when also passing force=1 to the
module when doing a 'modprobe'. This function is more general than the ACPI
test function and the function relying on ACPI could probably be removed.

This patch fixes several aspects of the probing for interrupts.
This patch reads the TPM's timeouts before probing for the interrupts. The
tpm_get_timeouts() function is invoked in polling mode and gets the proper
timeouts from the TPM so that we don't need to fall back to 2 minutes timeouts
for short duration commands while the interrupt probing is happening.
This patch introduces a variable probed_irq into the vendor structure that gets
the irq number if an interrupt is received while the the tpm_gen_interrupt()
function is run in polling mode during interrupt probing. Previously some
parts of tpm_gen_interrupt() were run in polling mode, then the irq variable
was set in the interrupt handler when an interrupt was received and execution
of tpm_gen_interrupt() ended up switching over to interrupt mode.
tpm_gen_interrupt() execution ended up on an event queue where it eventually
timed out since the probing handler doesn't wake any queues.
Before calling into free_irq() clear all interrupt flags that may have
been set by the TPM. The reason is that free_irq() will call into the probing
interrupt handler and may otherwise fool us into thinking that a real interrupt
happened (because we see the flags as being set) while the TPM's interrupt line
is not even connected to anything on the motherboard. This solves a problem
on one machine I did testing on (Thinkpad T60).
If a TPM claims to use a specifc interrupt, the probing is done as well
to verify that the interrupt is actually working. If a TPM indicates
that it does not use a specific interrupt (returns '0'), probe all interrupts
from 3 to 15.

This patch delays the (ACPI S3) suspend while the TPM is busy processing a
command and the TPM TIS driver is run in interrupt mode. This is the same
behavior as we already have it for the TPM TIS driver in polling mode.
Reasoning: Some of the TPM's commands advance the internal state of the TPM.
An example would be the extending of one of its PCR registers. Upper layers,
such as IMA or TSS (TrouSerS), would certainly want to be sure that the
command succeeded rather than getting an error code (-62 = -ETIME) that may
not give a conclusive answer as for what reason the command failed. Reissuing
such a command would put the TPM into the wrong state, so waiting for it to
finish is really the only option.
The downside is that some commands (key creation) can take a long time and
actually prevent the machine from entering S3 at all before the 20 second
timeout of the power management subsystem arrives.

This patch makes sure that if the TPM TIS interface is run in interrupt mode
(rather than polling mode) that all interrupts are enabled in the TPM's
interrupt enable register after a resume from ACPI S3 suspend. The registers
may either have been cleared by the TPM loosing its state during device sleep
or by the BIOS leaving the TPM in polling mode (after sending a command to
the TPM for starting it up again)
You may want to check if your TPM runs with interrupts by doing
cat /proc/interrupts | grep -i tpm
and see whether there is an entry or otherwise for it to use interrupts:
modprobe tpm_tis interrupts=1 [add 'itpm=1' for Intel TPM ]

This patch fixes the TPM's pubek sysfs entry that is accessible as long
as the TPM doesn't have an owner. It was necessary to shift the access to the
data by -10 -- the first byte immediately follows the 10 byte header. The
line
data = tpm_cmd.params.readpubek_out_buffer;
sets it at the offset '10' in the packet, so we can read the data array
starting at offset '0'.

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.

The first version of this patch proposed an arch/tile/drivers/ directory,
but the consensus was that this was probably a poor choice for a place to
group Tilera-specific drivers, and that in any case grouping by platform
was discouraged, and grouping by function was preferred.
This version of the patch addresses various issues raised in the
community, primarily the absence of sysfs integration. The sysfs
integration now handles passing information on sector size, page size,
and total partition size to userspace as well. In addition, we now
use a single "struct cdev" to manage all the partition minor devices,
and dynamically discover the correct number of partitions from the
hypervisor rather than using a module_param with a default value.
This driver has no particular "peer" drivers it can be grouped with.
It is sort of like an MTD driver for SPI ROM, but it doesn't group well
with the other MTD devices since it relies on hypervisor virtualization
to handle many of the irritating aspects of flash ROM management: sector
awareness, background read for sub-sector writes, bit examination to
determine whether a sector erase needs to be issued, etc. It is in fact
more like an EEPROM driver, but the hypervisor virtualization does require
a "flush" command if you wish to commit a sector write prior to writing
to a different sector, and this is sufficiently different from generic
I2C/SPI EEPROMs that as a result it doesn't group well with them either.
The simple character device is already in use by a range of Tilera
SPI ROM management tools, as well as by customers. In addition, using
the simple character device actually simplifies the userspace tools,
since they don't need to manage sector erase, background read, etc.
This both simplifies the code (since we can uniformly manage plain files
and the SPI ROM) as well as makes the user code portable to non-Linux
platforms that don't offer the same MTD ioctls.

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.

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.

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

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.

Fix up new system-call-related conflicts in
arch/x86/ia32/ia32entry.S
arch/x86/include/asm/unistd_32.h
arch/x86/include/asm/unistd_64.h
arch/x86/kernel/syscall_table_32.S
(name_to_handle_at()/open_by_handle_at() vs clock_adjtime()), and some
due to movement of get_jiffies_64() in:
kernel/time.c
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.

I forgot to move the digi*.h files from drivers/char/ to
drivers/staging/tty/
Thanks to Randy for pointing out the issue.

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.

This reverts commit c4ff4b829e.
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."

The ioctl file pointer was removed in commit 6caa76
"tty: now phase out the ioctl file pointer for good".
Thus fix the prototype for mgslpc_ioctl() and eliminate below warning:

of_platform_driver is getting removed, and a single platform_driver
can now support both devicetree and non-devicetree use cases. This
patch merges the two driver registrations.
