#1369810 — [PATCH 3.19.y-ckt 022/170] crypto: ccp - Add hash state import and export support

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Tom Lendacky <thomas.lendacky@amd.com>

commit 952bce9792e6bf36fda09c2e5718abb5d9327369 upstream.

Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
added a check to prevent ahash algorithms from successfully registering
if the import and export functions were not implemented. This prevents
an oops in the hash_accept function of algif_hash. This commit causes
the ccp-crypto module SHA support and AES CMAC support from successfully
registering and causing the ccp-crypto module load to fail because the
ahash import and export functions are not implemented.

Update the CCP Crypto API support to provide import and export support
for ahash algorithms.

#1369811 — [PATCH 3.19.y-ckt 029/170] net: irda: Fix use-after-free in irtty_open()

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Peter Hurley <peter@hurleysoftware.com>

commit 401879c57f01cbf2da204ad2e8db910525c6dbea upstream.

The N_IRDA line discipline may access the previous line discipline's closed
and already-fre private data on open [1].

The tty->disc_data field _never_ refers to valid data on entry to the
line discipline's open() method. Rather, the ldisc is expected to
initialize that field for its own use for the lifetime of the instance
(ie. from open() to close() only).

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Tom Lendacky <thomas.lendacky@amd.com>

commit b31dde2a5cb1bf764282abf934266b7193c2bc7c upstream.

Use a local variable for the exported and imported state so that
alignment is not an issue. On export, set a local variable from the
request context and then memcpy the contents of the local variable to
the export memory area. On import, memcpy the import memory area into
a local variable and then use the local variable to set the request
context.

#1369813 — [PATCH 3.19.y-ckt 026/170] crypto: ccp - Limit the amount of information exported

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Tom Lendacky <thomas.lendacky@amd.com>

commit d1662165ae612ec8b5f94a6b07e65ea58b6dce34 upstream.

Since the exported information can be exposed to user-space, instead of
exporting the entire request context only export the minimum information
needed.

#1369814 — [PATCH 3.19.y-ckt 028/170] 8250: use callbacks to access UART_DLL/UART_DLM

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Sebastian Frias <sf84@laposte.net>

commit 0b41ce991052022c030fd868e03877700220b090 upstream.

Some UART HW has a single register combining UART_DLL/UART_DLM
(this was probably forgotten in the change that introduced the
callbacks, commit b32b19b8ffc05cbd3bf91c65e205f6a912ca15d9)

Fixes: b32b19b8ffc0 ("[SERIAL] 8250: set divisor register correctly ...")

From: Ingo Molnar <mingo@kernel.org>

commit 590ee7dbd569a012df705a5204fc5f1066f52b8c upstream.

Now that we are using smpboot_thread_init() in init/main.c as well,
provide it for !CONFIG_SMP as well.

This addresses a !CONFIG_SMP build failure.

#1369816 — [PATCH 3.19.y-ckt 018/170] cpu: Defer smpboot kthread unparking until CPU known to scheduler

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

commit 00df35f991914db6b8bde8cf09808e19a9cffc3d upstream.

Currently, smpboot_unpark_threads() is invoked before the incoming CPU
has been added to the scheduler's runqueue structures.  This might
potentially cause the unparked kthread to run on the wrong CPU, since the
correct CPU isn't fully set up yet.

That causes a sporadic, hard to debug boot crash triggering on some
systems, reported by Borislav Petkov, and bisected down to:

  2a442c9c6453 ("x86: Use common outgoing-CPU-notification code")

This patch places smpboot_unpark_threads() in a CPU hotplug
notifier with priority set so that these kthreads are unparked just after
the CPU has been added to the runqueues.

#1369817 — [PATCH 3.19.y-ckt 046/170] crypto: ccp - memset request context to zero during import

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Tom Lendacky <thomas.lendacky@amd.com>

commit ce0ae266feaf35930394bd770c69778e4ef03ba9 upstream.

Since a crypto_ahash_import() can be called against a request context
that has not had a crypto_ahash_init() performed, the request context
needs to be cleared to insure there is no random data present. If not,
the random data can result in a kernel oops during crypto_ahash_update().

commit e7597e69dec59b65c5525db1626b9d34afdfa678 upstream.

'max_discard_sectors' is in sectors, while 'stripe' is in bytes.

This fixes the problem where DISCARD would get disabled on some larger
RAID5 configurations (6 or more drives in my testing), while it worked
as expected with smaller configurations.

From: Hans de Goede <hdegoede@redhat.com>

commit 5c915c68763889f0183a1cc61c84bb228b60124a upstream.

On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).

This turns out to be caused by max-width (924) not being a multiple of 16.

We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.

#1369820 — [PATCH 3.19.y-ckt 043/170] mtd: onenand: fix deadlock in onenand_block_markbad

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Aaro Koskinen <aaro.koskinen@iki.fi>

commit 5e64c29e98bfbba1b527b0a164f9493f3db9e8cb upstream.

Commit 5942ddbc500d ("mtd: introduce mtd_block_markbad interface")
incorrectly changed onenand_block_markbad() to call mtd_block_markbad
instead of onenand_chip's block_markbad function. As a result the function
will now recurse and deadlock. Fix by reverting the change.

From: Peter Hurley <peter@hurleysoftware.com>

commit f33798deecbd59a2955f40ac0ae2bc7dff54c069 upstream.

commit 9ce119f318ba ("tty: Fix GPF in flush_to_ldisc()") fixed a
GPF caused by a line discipline which does not define a receive_buf()
method.

However, the vt driver (and speakup driver also) pushes selection
data directly to the line discipline receive_buf() method via
tty_ldisc_receive_buf(). Fix the same problem in tty_ldisc_receive_buf().

#1369825 — [PATCH 3.19.y-ckt 044/170] PCI: Disable IO/MEM decoding for devices with non-compliant BARs

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Bjorn Helgaas <bhelgaas@google.com>

commit b84106b4e2290c081cdab521fa832596cdfea246 upstream.

The PCI config header (first 64 bytes of each device's config space) is
defined by the PCI spec so generic software can identify the device and
manage its usage of I/O, memory, and IRQ resources.

Some non-spec-compliant devices put registers other than BARs where the
BARs should be.  When the PCI core sizes these "BARs", the reads and writes
it does may have unwanted side effects, and the "BAR" may appear to
describe non-sensical address space.

Add a flag bit to mark non-compliant devices so we don't touch their BARs.
Turn off IO/MEM decoding to prevent the devices from consuming address
space, since we can't read the BARs to find out what that address space
would be.

#1369826 — [PATCH 3.19.y-ckt 049/170] mmc: sdhci: fix data timeout (part 2)

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Russell King <rmk+kernel@arm.linux.org.uk>

commit 7f05538af71c7d30b5fc821cbe9f318edc645961 upstream.

The calculation for the timeout based on the number of card clocks is
incorrect.  The calculation assumed:

	timeout in microseconds = clock cycles / clock in Hz

which is clearly a several orders of magnitude wrong.  Fix this by
multiplying the clock cycles by 1000000 prior to dividing by the Hz
based clock.  Also, as per part 1, ensure that the division rounds
up.

As this needs 64-bit math via do_div(), avoid it if the clock cycles
is zero.

#1369828 — [PATCH 3.19.y-ckt 033/170] usb: retry reset if a device times out

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Oliver Neukum <oneukum@suse.com>

commit 264904ccc33c604d4b3141bbd33808152dfac45b upstream.

Some devices I got show an inability to operate right after
power on if they are already connected. They are beyond recovery
if the descriptors are requested multiple times. So in case of
a timeout we rather bail early and reset again. But it must be
done only on the first loop lest we get into a reset/time out
spiral that can be overcome with a retry.

This patch is a rework of a patch that fell through the cracks.

#1369830 — [PATCH 3.19.y-ckt 038/170] perf tools: Dont stop PMU parsing on alias parse error

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Andi Kleen <ak@linux.intel.com>

commit 940db6dcd3f4659303fdf6befe7416adc4d24118 upstream.

When an error happens during alias parsing currently the complete
parsing of all attributes of the PMU is stopped. This is breaks old perf
on a newer kernel that may have not-yet-know alias attributes (such as
.scale or .per-pkg).

Continue when some attribute is unparseable.

This is IMHO a stable candidate and should be backported to older
versions to avoid problems with newer kernels.

v2: Print warnings when something goes wrong.
v3: Change warning to debug output
