From: Andrey Ryabinin <aryabinin@virtuozzo.com>
commit e459dfeeb64008b2d23bdf600f03b3605dbb8152 upstream.
ip6addrlbl_get() has never worked. If ip6addrlbl_hold() succeeded,
ip6addrlbl_get() will exit with '-ESRCH'. If ip6addrlbl_hold() failed,
ip6addrlbl_get() will use about to be free ip6addrlbl_entry pointer.
Fix this by inverting ip6addrlbl_hold() check.

3.19.8-ckt13 -stable review patch. If anyone has any objections, please let me know.

From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
commit 8135cf8b092723dbfcc611fe6fdcb3a36c9951c5 upstream.
Double fetch vulnerabilities that happen when a variable is
fetched twice from shared memory but a security check is only
performed the first time.
The xen_pcibk_do_op function performs a switch statements on the op->cmd
value which is stored in shared memory. Interestingly this can result
in a double fetch vulnerability depending on the performed compiler
optimization.
This patch fixes it by saving the xen_pci_op command before
processing it. We also use 'barrier' to make sure that the
compiler does not perform any optimization.
This is part of XSA155.

[ Upstream commit ed7d42e24effbd3681e909711a7a2119a85e9217 ]
In case of a tx queue timeout every transmit is blocked until the
QCA7000 resets himself and triggers a sync which makes the driver
flushs the tx ring. So avoid this blocking situation by triggering
the sync immediately after the timeout. Waking the queue doesn't
make sense in this situation.

| Message-ID | <qSPKZ-7CF-75@gated-at.bofh.it> |
| In reply to | #1312635 |
3.19.8-ckt13 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Stefan Agner <stefan@agner.ch>
commit 9c17190595840b4ed30e8d5f286636ceb28aae4f upstream.
Linux on Vybrid used several different L2 latencies so far, none
of them seem to be the right ones. According to the application note
AN4947 ("Understanding Vybrid Architecture"), the tag portion runs
on CPU clock and is inside the L2 cache controller, whereas the data
portion is stored in the external SRAM running on platform clock.
Hence it is likely that the correct value requires a higher data
latency then tag latency.
These are the values which have been used so far:
- The mainline values:
arm,data-latency = <1 1 1>;
arm,tag-latency = <2 2 2>;
Those values have lead to problems on higher clocks. They look
like a poor translation from the reset values (missing +1 offset
and a mix up between tag/latency values).
- The Linux 3.0 (SoC vendor BSP) values (converted to DT notation):
arm,data-latency = <4 2 3>
arm,tag-latency = <4 2 3>
The cache initialization function along with the value matches the
i.MX6 code from the same kernel, so it seems that those values have
just been copied.
- The Colibri values:
arm,data-latency = <2 1 2>;
arm,tag-latency = <3 2 3>;
Those were a mix between the values of the Linux 3.0 based BSP and
the mainline values above.
- The SoC Reset values (converted to DT notation):
arm,data-latency = <3 3 3>;
arm,tag-latency = <2 2 2>;
So far there is no official statement on what the correct values are.
See also the related Freescale community thread:
https://community.freescale.com/message/579785#579785
For now, the reset values seem to be the best bet. Remove all other
"bogus" values and use the reset value on vf610.dtsi level.

From: Nicolas Dichtel <nicolas.dichtel@6wind.com>
[ Upstream commit 6a61d4dbf4f54b5683e0f1e58d873cecca7cb977 ]
Parameters were updated only if the kernel was unable to find the tunnel
with the new parameters, ie only if core pamareters were updated (keys,
addr, link, type).
Now it's possible to update ttl, hoplimit, flowinfo and flags.

3.19.8-ckt13 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: David Turner <novalis@novalis.org>
commit a4dad1ae24f850410c4e60f22823cba1289b8d52 upstream.
In ext4, the bottom two bits of {a,c,m}time_extra are used to extend
the {a,c,m}time fields, deferring the year 2038 problem to the year
2446.
When decoding these extended fields, for times whose bottom 32 bits
would represent a negative number, sign extension causes the 64-bit
extended timestamp to be negative as well, which is not what's
intended. This patch corrects that issue, so that the only negative
{a,c,m}times are those between 1901 and 1970 (as per 32-bit signed
timestamps).
Some older kernels might have written pre-1970 dates with 1,1 in the
extra bits. This patch treats those incorrectly-encoded dates as
pre-1970, instead of post-2311, until kernel 4.20 is released.
Hopefully by then e2fsck will have fixed up the bad data.
Also add a comment explaining the encoding of ext4's extra {a,c,m}time
bits.

commit 4c5e354a974214dfb44cd23fa0429327693bc3ea upstream.
When shutting down the device, the struct ser_cardstate must not be
kfree()d immediately after the call to platform_device_unregister()
since the embedded struct platform_device is still in use.
Move the kfree() call to the release method instead.

From: "Jason A. Donenfeld" <Jason@zx2c4.com>
commit 70d906bc17500edfa9bdd8c8b7e59618c7911613 upstream.
Some ciphers actually support encrypting zero length plaintexts. For
example, many AEAD modes support this. The resulting ciphertext for
those winds up being only the authentication tag, which is a result of
the key, the iv, the additional data, and the fact that the plaintext
had zero length. The blkcipher constructors won't copy the IV to the
right place, however, when using a zero length input, resulting in
some significant problems when ciphers call their initialization
routines, only to find that the ->iv parameter is uninitialized. One
such example of this would be using chacha20poly1305 with a zero length
input, which then calls chacha20, which calls the key setup routine,
which eventually OOPSes due to the uninitialized ->iv member.

From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
commit a396f3a210c3a61e94d6b87ec05a75d0be2a60d0 upstream.
Otherwise an guest can subvert the generic MSI code to trigger
an BUG_ON condition during MSI interrupt freeing:
for (i = 0; i < entry->nvec_used; i++)
BUG_ON(irq_has_action(entry->irq + i));
Xen PCI backed installs an IRQ handler (request_irq) for
the dev->irq whenever the guest writes PCI_COMMAND_MEMORY
(or PCI_COMMAND_IO) to the PCI_COMMAND register. This is
done in case the device has legacy interrupts the GSI line
is shared by the backend devices.
To subvert the backend the guest needs to make the backend
to change the dev->irq from the GSI to the MSI interrupt line,
make the backend allocate an interrupt handler, and then command
the backend to free the MSI interrupt and hit the BUG_ON.
Since the backend only calls 'request_irq' when the guest
writes to the PCI_COMMAND register the guest needs to call
XEN_PCI_OP_enable_msi before any other operation. This will
cause the generic MSI code to setup an MSI entry and
populate dev->irq with the new PIRQ value.
Then the guest can write to PCI_COMMAND PCI_COMMAND_MEMORY
and cause the backend to setup an IRQ handler for dev->irq
(which instead of the GSI value has the MSI pirq). See
'xen_pcibk_control_isr'.
Then the guest disables the MSI: XEN_PCI_OP_disable_msi
which ends up triggering the BUG_ON condition in 'free_msi_irqs'
as there is an IRQ handler for the entry->irq (dev->irq).
Note that this cannot be done using MSI-X as the generic
code does not over-write dev->irq with the MSI-X PIRQ values.
The patch inhibits setting up the IRQ handler if MSI or
MSI-X (for symmetry reasons) code had been called successfully.
P.S.
Xen PCIBack when it sets up the device for the guest consumption
ends up writting 0 to the PCI_COMMAND (see xen_pcibk_reset_device).
XSA-120 addendum patch removed that - however when upstreaming said
addendum we found that it caused issues with qemu upstream. That
has now been fixed in qemu upstream.
This is part of XSA-157

Without this patch, internal speaker and line-out work,
but front headphone output jack stays silent on the
Mac Pro 4,1.
This code path also gets executed on the MacPro 5,1 due
to identical codec SSID, but i don't know if it has any
positive or adverse effects there or not.
(v2) Implement feedback from Takashi Iwai: Reuse

From: Hans Yang <hansy@nvidia.com>
commit 464ad8c43a9ead98c2b0eaed86bea727f2ad106e upstream.
When a USB 3.0 mass storage device is disconnected in transporting
state, storage device driver may handle it as a transport error and
reset the device by invoking usb_reset_and_verify_device()
and following could happen:
in usb_reset_and_verify_device():
udev->bos = NULL;
For U1/U2 enabled devices, driver will disable LPM, and in some
conditions:
from usb_unlocked_disable_lpm()
--> usb_disable_lpm()
--> usb_enable_lpm()
udev->bos->ss_cap->bU1devExitLat;
And it causes 'NULL pointer' and 'kernel panic':
[ 157.976257] Unable to handle kernel NULL pointer dereference
at virtual address 00000010
...
[ 158.026400] PC is at usb_enable_link_state+0x34/0x2e0

...
[ 158.214954] Kernel panic - not syncing: Fatal exception
This commit moves 'udev->bos = NULL' behind usb_unlocked_disable_lpm()
to prevent from NULL pointer access.
Issue can be reproduced by following setup:
1) A SS pen drive behind a SS hub connected to the host.
2) Transporting data between the pen drive and the host.
3) Abruptly disconnect hub and pen drive from host.
4) With a chance it crashes.

From: David Howells <dhowells@redhat.com>
commit b4a1b4f5047e4f54e194681125c74c0aa64d637d upstream.
This fixes CVE-2015-7550.
There's a race between keyctl_read() and keyctl_revoke(). If the revoke
happens between keyctl_read() checking the validity of a key and the key's
semaphore being taken, then the key type read method will see a revoked key.
This causes a problem for the user-defined key type because it assumes in
its read method that there will always be a payload in a non-revoked key
and doesn't check for a NULL pointer.
Fix this by making keyctl_read() check the validity of a key after taking
semaphore instead of before.
I think the bug was introduced with the original keyrings code.
This was discovered by a multithreaded test program generated by syzkaller
(http://github.com/google/syzkaller). Here's a cleaned up version:
#include <sys/types.h>
#include <keyutils.h>
#include <pthread.h>
void *thr0(void *arg)
{
key_serial_t key = (unsigned long)arg;
keyctl_revoke(key);
return 0;
}
void *thr1(void *arg)
{
key_serial_t key = (unsigned long)arg;
char buffer[16];
keyctl_read(key, buffer, 16);
return 0;
}
int main()
{
key_serial_t key = add_key("user", "%", "foo", 3, KEY_SPEC_USER_KEYRING);
pthread_t th[5];
pthread_create(&th[0], 0, thr0, (void *)(unsigned long)key);
pthread_create(&th[1], 0, thr1, (void *)(unsigned long)key);
pthread_create(&th[2], 0, thr0, (void *)(unsigned long)key);
pthread_create(&th[3], 0, thr1, (void *)(unsigned long)key);
pthread_join(th[0], 0);
pthread_join(th[1], 0);
pthread_join(th[2], 0);
pthread_join(th[3], 0);
return 0;
}
Build as:
cc -o keyctl-race keyctl-race.c -lkeyutils -lpthread
Run as:
while keyctl-race; do :; done
as it may need several iterations to crash the kernel. The crash can be
summarised as:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000010

From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
commit 7cfb905b9638982862f0331b36ccaaca5d383b49 upstream.
Otherwise just continue on, returning the same values as
previously (return of 0, and op->result has the PIRQ value).
This does not change the behavior of XEN_PCI_OP_disable_msi[|x].
The pci_disable_msi or pci_disable_msix have the checks for
msi_enabled or msix_enabled so they will error out immediately.
However the guest can still call these operations and cause
us to disable the 'ack_intr'. That means the backend IRQ handler
for the legacy interrupt will not respond to interrupts anymore.
This will lead to (if the device is causing an interrupt storm)
for the Linux generic code to disable the interrupt line.
Naturally this will only happen if the device in question
is plugged in on the motherboard on shared level interrupt GSI.
This is part of XSA-157

From: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com>
[ Upstream commit cb5e173ed7c03a0d4630ce68a95a186cce3cc872 ]
SCTP echoes a cookie o INIT ACK chunks that contains a timestamp, for
detecting stale cookies. This cookie is echoed back to the server by the
client and then that timestamp is checked.
Thing is, if the listening socket is using packet timestamping, the
cookie is encoded with ktime_get() value and checked against
ktime_get_real(), as done by __net_timestamp().
The fix is to sctp also use ktime_get_real(), so we can compare bananas
with bananas later no matter if packet timestamping was enabled or not.
Fixes: 52db882f3fc2 ("net: sctp: migrate cookie life from timeval to ktime")
