commit c30bc94758ae2a38a5eb31767c1985c0aae0950b upstream.
L2TP for example uses NLA_MSECS like this:
policy:
[L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, },
code:
if (info->attrs[L2TP_ATTR_RECV_TIMEOUT])
cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]);
As nla_get_msecs() is essentially nla_get_u64() plus the
conversion to a HZ-based value, this will not properly
reject attributes from userspace that aren't long enough
and might overrun the message.
Add NLA_MSECS to the attribute minlen array to check the
size properly.

commit 3bf3f8b19d2bfccc40f13c456bf339fd8f535ebc upstream.
Callers to __acpi_ioremap_fast() pass the bit_width that they found in the
acpi_generic_address structure. Convert from bits to bytes when passing to
__acpi_find_iomap() - as it wants to see bytes, not bits.

commit 8bdafa39a47265bc029838b35cc6585f69224afa upstream.
The icswx code introduced an A-B B-A deadlock:

lock(&anon_vma->mutex);
lock(&mm->mmap_sem);
lock(&anon_vma->mutex);

Instead of using the mmap_sem to keep mm_users constant, take the
page table spinlock.

commit 8feaa43494cee5e938fd5a57b9e9bf1c827e6ccd upstream.
Since commit 188917e183cf9ad0374b571006d0fc6d48a7f447, /proc/ppc64 is a
symlink to /proc/powerpc/. That means that creating /proc/ppc64/eeh will
end up with a unaccessible file, that is not listed under /proc/powerpc/
and, then, not listed under /proc/ppc64/.
Creating /proc/powerpc/eeh fixes that problem and maintain the
compatibility intended with the ppc64 symlink.

commit a11940978bd598e65996b4f807cf4904793f7025 upstream.
If we echo an address the hypervisor doesn't like to

# echo 0x10000000000 > /sys/devices/system/memory/probe
kernel BUG at arch/powerpc/mm/hash_utils_64.c:541!
The backtrace is:

SyS_write
In create_section_mapping we BUG if htab_bolt_mapping returned
an error. A better approach is to return an error which will
propagate back to userspace.

commit 6083184269fd723affca4f6340e491950267622a upstream.
During memory hotplug testing, I got the following warning:
ERROR: Bad of_node_put() on /memory@0

kref_put
of_node_put
of_find_node_by_type
hot_add_node_scn_to_nid
hot_add_scn_to_nid
memory_add_physaddr_to_nid
...
of_find_node_by_type() loop does the of_node_put for us so we only
need the handle the case where we terminate the loop early.
As suggested by Stephen Rothwell we can do the of_node_put
unconditionally outside of the loop since of_node_put handles a
NULL argument fine.

commit a3fbbde70a0cec017f2431e8f8de208708c76acc upstream.
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

No one in their right mind would expect statfs() to not work on a
automounter managed mount point. Fix it.
[ I'm not sure about the "no one in their right mind" part. It's not
mounted, and you didn't ask for it to be mounted. But nobody will
really care, and this probably makes it match previous semantics, so..

This is because bdev holds on to disk but disk doesn't pin the
associated queue. If a SCSI device is removed while the device is
still open, the sdev puts the base reference to the queue on release.
When the bdev is finally released, the associated queue is already
gone along with the bdi and bdev_inode_switch_bdi() ends up
dereferencing already freed bdi.
Even if it were not for this bug, disk not holding onto the associated
queue is very unusual and error-prone.
Fix it by making add_disk() take an extra reference to its queue and
put it on disk_release() and ensuring that disk and its fops owner are
put in that order after all accesses to the disk and queue are
complete.

commit dc6f55e9f8dac4b6479be67c5c9128ad37bb491f upstream.
The sunrpc layer keeps a cache of recently used credentials and
'unx_match' is used to find the credential which matches the current
process.
However unx_match allows a match when the cached credential has extra
groups at the end of uc_gids list which are not in the process group list.
So if a process with a list of (say) 4 group accesses a file and gains
access because of the last group in the list, then another process
with the same uid and gid, and a gid list being the first tree of the
gids of the original process tries to access the file, it will be
granted access even though it shouldn't as the wrong rpc credential
will be used.

commit 0167ac67ff6f35bf2364f7672c8012b0cd40277f upstream.
Fix for issue : While discovery is in progress, hot unplug and hot plug of
enclosure connected to the controller card is causing system to hang.
When a device is in the process of being detected at driver load time then
if it is removed, the device that is no longer present will not be added
to the list. So the code in _scsih_probe_sas() is rearranged as such so
the devices that failed to be detected are not added to the list.

commit f7c9c6bb14f3104608a3a83cadea10a6943d2804 upstream.
When looking at memory consumption issues I noticed quite a
lot of memory in the kmalloc-2048 bucket:
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
6561 6471 98% 2.30K 243 27 15552K kmalloc-2048
Over 15MB. slub debug shows that cfq is responsible for almost
all of it:
# sort -nr /sys/kernel/slab/kmalloc-2048/alloc_calls
6402 .cfq_init_queue+0xec/0x460 age=43423/43564/43655 pid=1 cpus=4,11,13
In scsi_alloc_sdev we do scsi_alloc_queue but if slave_alloc
fails we don't free it with scsi_free_queue.
The patch below fixes the issue:
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
135 72 53% 2.30K 5 27 320K kmalloc-2048
# cat /sys/kernel/slab/kmalloc-2048/alloc_calls

commit 8cd79f24350826b81e16990d9e12bc878e67d385 upstream.
This patch addresses an issue with buggy userspace code sending I/O
via scsi-generic that does not explictly clear their associated read
buffers. It adds an explict memset of the first SGL entry within
tcm_loop_new_cmd_map() for SCF_SCSI_CONTROL_SG_IO_CDB payloads that
are currently guaranteed to be a single SGL by target-core code.
This issue is a side effect of the v3.1-rc1 merge to remove the
extra memcpy between certain control CDB types using a contigious
+ cleared buffer in target-core, and performing a memcpy into the
SGL list within tcm_loop.
It was originally mainfesting itself by udev + scsi_id + scsi-generic
not properly setting up the expected /dev/disk/by-id/ symlinks because
the INQUIRY payload was containing extra bogus data preventing the
proper NAA IEEE WWN from being parsed by userspace.

commit b2c0a863e14676fa5760c6d828fd373288e2f64a upstream.
Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed. The idle callback routine could
then schedule a delayed suspend for some time later.
However this behavior was changed by commit
f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
notification after failing suspend). No notifications were sent, and
there was no clear mechanism to retry failed suspends.
This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down. A companion
patch changes the PM core's behavior, but we also need to change the
USB core. In particular, this patch (as1493) updates the device's
last_busy time when an autosuspend fails, so that the PM core will
retry the autosuspend in the future when the delay time expires
again.

commit 886486b792e4f6f96d4fbe8ec5bf20811cab7d6a upstream.
Originally, the runtime PM core would send an idle notification
whenever a suspend attempt failed. The idle callback routine could
then schedule a delayed suspend for some time later.
However this behavior was changed by commit
f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle
notification after failing suspend). No notifications were sent, and
there was no clear mechanism to retry failed suspends.
This caused problems for the usbhid driver, because it fails
autosuspend attempts as long as a key is being held down. Therefore
this patch (as1492) adds a mechanism for retrying failed
autosuspends. If the callback routine updates the last_busy field so
that the next autosuspend expiration time is in the future, the
autosuspend will automatically be rescheduled.

commit 3f198dfee49d2e9c30583c62b0c79286c78c7b44 upstream.
Help text under choice menu is never displayed because it does not have
symbol name associated with it, however many kconfigs have help text
under choice, assuming that it will be displayed when user selects help.
for example in Kconfig if we have:
choice
prompt "Choice"
---help---
HELP TEXT ...
config A
bool "A"
config B
bool "B"
endchoice
Without this patch "HELP TEXT" is not displayed when user selects help
option when "Choice" is highlighted from menuconfig or xconfig or
gconfig.
This patch changes the logic in menu_get_ext_help to display help for
cases which dont have symbol names like choice.

commit 64912e997f0fe13512e4c7b90e4f7c11cb922ab5 upstream.
Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.

commit a18cee15ed4c8b6a35f96b7b26a46bac32e04bd9 upstream.
Allow the user to override whether MSIs are enabled
or not on supported ASICs. MSIs are disabled by default
on IGP chips as they tend not to work. However certain
IGP chips only seem to work with MSIs enabled.
I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is. This will at least make diagnosing
and working around the problem much easier.

commit 340764465aa4a586ca332e61ae64883e5ad6f183 upstream.
Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4
we could end up bouncing connector status btw disconnected and unknown.
When connector status change a call to output_poll_changed happen which
in turn ask again for detect but with force set.
So set the load detect flags whenever we report the connector as
connected or unknown this avoid bouncing btw disconnected and unknown.

commit 51e4152a969aa6d2306492ebf143932dcb535c9b upstream.
Some BIOS report invalid pins as digital output pins. The driver checks
the connection but it doesn't do it fully correctly, and it leaves some
undefined value as the audio-out widget, which makes the driver spewing
warnings. This patch fixes the issue.

commit 862a6244eb9f9f5123fe819454fcfcae0ee1f2f9 upstream.
If the device is unplugged while running, it is possible for a PCM
device to be closed after the disconnect callback has returned. This
means that kill_stream_urb() and disable_iso_interface() would try to
access already-invalid or freed USB data structures.
The function free_usb_related_resources() was intended to prevent this,
but forgot to clear the affected variables.

[ Upstream commit b64b73d7d0c480f75684519c6134e79d50c1b341 ]
This resolves a regression seen by some users of bridging.
Some users use the bridge like a dummy device.
They expect to be able to put an IPv6 address on the device
with no ports attached. Although there are better ways of doing
this, there is no reason to not allow it.
Note: the bridge still will reflect the state of ports in the
bridge if there are any added.
