From: Arnd Bergmann <arnd(a)arndb.de>
[ Upstream commit fa23b9d1b89fdc34f296f02e496a20aeff5736be ]
This driver uses the MSI domain but has no strict dependency on PCI_MSI, so we
may run into a build failure when CONFIG_GENERIC_MSI_IRQ_DOMAIN is disabled:

Selecting the option from this driver seems to solve this nicely, though I could
not find any other instance of this in irqchip drivers.

There exist two Mediatek iommu drivers for the two different
generations of the device. But both drivers have the same name
"mtk-iommu". This breaks the registration of the second driver:
Error: Driver 'mtk-iommu' is already registered, aborting...
Fix this by changing the name for first generation to
"mtk-iommu-v1".

TUXEDO BU1406 does not implement active multiplexing mode properly,
and takes around 550 ms in i8042_set_mux_mode(). Given that the
device does not have external AUX port, there is no downside in
disabling the MUX mode.

Subject: icmp: don't fail on fragment reassembly time exceeded
From: Matteo Croce <mcroce(a)redhat.com>
[ Upstream commit 258bbb1b0e594ad5f5652cb526b3c63e6a7fad3d ]
The ICMP implementation currently replies to an ICMP time exceeded message
(type 11) with an ICMP host unreachable message (type 3, code 1).
However, time exceeded messages can either represent "time to live exceeded
in transit" (code 0) or "fragment reassembly time exceeded" (code 1).
Unconditionally replying to "fragment reassembly time exceeded" with
host unreachable messages might cause unjustified connection resets
which are now easily triggered as UFO has been removed, because, in turn,
sending large buffers triggers IP fragmentation.
The issue can be easily reproduced by running a lot of UDP streams
which is likely to trigger IP fragmentation:
# start netserver in the test namespace
ip netns add test
ip netns exec test netserver
# create a VETH pair
ip link add name veth0 type veth peer name veth0 netns test
ip link set veth0 up
ip -n test link set veth0 up
for i in $(seq 20 29); do
# assign addresses to both ends
ip addr add dev veth0 192.168.$i.1/24
ip -n test addr add dev veth0 192.168.$i.2/24
# start the traffic
netperf -L 192.168.$i.1 -H 192.168.$i.2 -t UDP_STREAM -l 0 &
done
# wait
send_data: data send error: No route to host (errno 113)
netperf: send_omni: send_data failed: No route to host
We need to differentiate instead: if fragment reassembly time exceeded
is reported, we need to silently drop the packet,
if time to live exceeded is reported, maintain the current behaviour.
In both cases increment the related error count "icmpInTimeExcds".
While at it, fix a typo in a comment, and convert the if statement
into a switch to mate it more readable.

Subject: Ib/hfi1: Return actual operational VLs in port info query
From: Patel Jay P <jay.p.patel(a)intel.com>
[ Upstream commit 00f9203119dd2774564407c7a67b17d81916298b ]
__subn_get_opa_portinfo stores value returned by hfi1_get_ib_cfg() as
operational vls. hfi1_get_ib_cfg() returns vls_operational field in
hfi1_pportdata. The problem with this is that the value is always equal
to vls_supported field in hfi1_pportdata.
The logic to calculate operational_vls is to set value passed by FM
(in __subn_set_opa_portinfo routine). If no value is passed then
default value is stored in operational_vls.
Field actual_vls_operational is calculated on the basis of buffer
control table. Hence, modifying hfi1_get_ib_cfg() to return
actual_operational_vls when used with HFI1_IB_CFG_OP_VLS parameter

From: Parav Pandit <parav(a)mellanox.com>
[ Upstream commit 99260132fde7bddc6e0132ce53da94d1c9ccabcb ]
The original code only took into consideration the largest header
possible after the IB_BTH_BYTES. This was incorrect, as the largest
possible header size is the largest possible combination of headers we
might run into. The new code accounts for all possible headers in the
largest possible combination and subtracts that from the MTU to make
sure that all packets will fit on the wire.

Subject: GFS2: Take inode off order_write list when setting jdata flag
From: Bob Peterson <rpeterso(a)redhat.com>
[ Upstream commit cc555b09d8c3817aeebda43a14ab67049a5653f7 ]
This patch fixes a deadlock caused when the jdata flag is set for
inodes that are already on the ordered write list. Since it is
on the ordered write list, log_flush calls gfs2_ordered_write which
calls filemap_fdatawrite. But since the inode had the jdata flag
set, that calls gfs2_jdata_writepages, which tries to start a new
transaction. A new transaction cannot be started because it tries
to acquire the log_flush rwsem which is already locked by the log
flush operation.
The bottom line is: We cannot switch an inode from ordered to jdata
until we eliminate any ordered data pages (via log flush) or any
log_flush operation afterward will create the circular dependency
above. So we need to flush the log before setting the diskflags to
switch the file mode, then we need to remove the inode from the
ordered writes list.
Before this patch, the log flush was done for jdata->ordered, but
that's wrong. If we're going from jdata to ordered, we don't need
to call gfs2_log_flush because the call to filemap_fdatawrite will
do it for us:
filemap_fdatawrite() -> __filemap_fdatawrite_range()
__filemap_fdatawrite_range() -> do_writepages()
do_writepages() -> gfs2_jdata_writepages()
gfs2_jdata_writepages() -> gfs2_log_flush()
This patch modifies function do_gfs2_set_flags so that if a file
has its jdata flag set, and it's already on the ordered write list,
the log will be flushed and it will be removed from the list
before setting the flag.

This patch fixes netdev->features for Extended Socket network device.
Currently Extended Socket network device's netdev->feature claims
NETIF_F_HW_CSUM, however this is completely wrong. There's no feature
of checksum offloading.
That causes invalid TCP/UDP checksum and packet rejection when IP
forwarding from Extended Socket network device to other network device.
NETIF_F_HW_CSUM should be omitted.

Dan's static analysis says:
drivers/video/fbdev/controlfb.c:560 control_setup()
error: buffer overflow 'control_mac_modes' 20 <= 21
Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22,
which may lead to an out of bounds read when parsing vmode commandline
options.
The bug was introduced in v2.4.5.6, when 2 new modes were added to
macmodes.h, but control_mac_modes[] wasn't updated:
https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.…
Augment control_mac_modes[] with the two new video modes to fix this.

From: Daniel Drake <drake(a)endlessm.com>
[ Upstream commit 822f5845f710e57d7e2df1fd1ee00d6e19d334fe ]
The Intel Compute Stick STCK1A8LFC and Weibu F3C platforms both
log 2 error messages during boot:
efi: requested map not found.
esrt: ESRT header is not in the memory map.
Searching the web, this seems to affect many other platforms too.
Since these messages are logged as errors, they appear on-screen during
the boot process even when using the "quiet" boot parameter used by
distros.
Demote the ESRT error to a warning so that it does not appear on-screen,
and delete the error logging from efi_mem_desc_lookup; both callsites
of that function log more specific messages upon failure.
Out of curiosity I looked closer at the Weibu F3C. There is no entry in
the UEFI-provided memory map which corresponds to the ESRT pointer, but
hacking the code to map it anyway, the ESRT does appear to be valid with
2 entries.

omap_gem_dmabuf_mmap() returns an error (with a WARN) when called for a
buffer which is allocated with dma_alloc_*(). This prevents dmabuf mmap
from working on SoCs without DMM, e.g. AM4 and OMAP3.
I could not find any reason for omap_gem_dmabuf_mmap() rejecting such
buffers, and just removing the if() fixes the limitation.

From: Arnd Bergmann <arnd(a)arndb.de>
[ Upstream commit 655d9ca9ac075da1ef2a45012ba48a39f6eb1f58 ]
The AMD ACP driver adds "-I../acp -I../acp/include" to the gcc command
line, which makes no sense, since these are evaluated relative to the
build directory. When we build with "make W=1", they instead cause
a warning:
cc1: error: ../acp/: No such file or directory [-Werror=missing-include-dirs]
cc1: error: ../acp/include: No such file or directory [-Werror=missing-include-dirs]
cc1: all warnings being treated as errors

This removes the subdir-ccflags variable that evidently did not
serve any purpose here.

Subject: Drivers: hv: util: move waiting for release to hv_utils_transport itself
From: Vitaly Kuznetsov <vkuznets(a)redhat.com>
[ Upstream commit e9c18ae6eb2b312f16c63e34b43ea23926daa398 ]
Waiting for release_event in all three drivers introduced issues on release
as on_reset() hook is not always called. E.g. if the device was never
opened we will never get the completion.
Move the waiting code to hvutil_transport_destroy() and make sure it is
only called when the device is open. hvt->lock serialization should
guarantee the absence of races.

[ Upstream commit 288e7560e4d3e259aa28f8f58a8dfe63627a1bf6 ]
The used 0x1f mask is only valid for am335x family of SoC, different family
using this type of crossbar might have different number of electable
events. In case of am43xx family 0x3f mask should have been used for
example.
Instead of trying to handle each family's mask, just use u8 type to store
the mux value since the event offsets are aligned to byte offset.

Subject: dmaengine: rcar-dmac: use TCRB instead of TCR for residue
From: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx(a)renesas.com>
[ Upstream commit 847449f23dcbff68234525f90dd53c7c7db18cad ]
SYS/RT/Audio DMAC includes independent data buffers for reading
and writing. Therefore, the read transfer counter and write transfer
counter have different values.
TCR indicates read counter, and TCRB indicates write counter.
The relationship is like below.
TCR TCRB
[SOURCE] -> [DMAC] -> [SINK]
In the MEM_TO_DEV direction, what really matters is how much data has
been written to the device. If the DMA is interrupted between read and
write, then, the data doesn't end up in the destination, so shouldn't
be counted. TCRB is thus the register we should use in this cases.
In the DEV_TO_MEM direction, the situation is more complex. Both the
read and write side are important. What matters from a data consumer
point of view is how much data has been written to memory.
On the other hand, if the transfer is interrupted between read and
write, we'll end up losing data. It can also be important to report.
In the MEM_TO_MEM direction, what matters is of course how much data
has been written to memory from data consumer point of view.
Here, because read and write have independent data buffers, it will
take a while for TCR and TCRB to become equal. Thus we should check
TCRB in this case, too.
Thus, all cases we should check TCRB instead of TCR.
Without this patch, Sound Capture has noise after PluseAudio support
(= 07b7acb51d2 ("ASoC: rsnd: update pointer more accurate")), because
the recorder will use wrong residue counter which indicates transferred
from sound device, but in reality the data was not yet put to memory
and recorder will record it.

Since the previous setup always sets the PLL using crystal 26MHz, this

flexibility for assigning extra member for determining the PLL source

Subject: btrfs: add missing memset while reading compressed inline extents
From: Zygo Blaxell <ce3g8jdj(a)umail.furryterror.org>
[ Upstream commit e1699d2d7bf6e6cce3e1baff19f9dd4595a58664 ]
This is a story about 4 distinct (and very old) btrfs bugs.
Commit c8b978188c ("Btrfs: Add zlib compression support") added
three data corruption bugs for inline extents (bugs #1-3).
Commit 93c82d5750 ("Btrfs: zero page past end of inline file items")
fixed bug #1: uncompressed inline extents followed by a hole and more
extents could get non-zero data in the hole as they were read. The fix
was to add a memset in btrfs_get_extent to zero out the hole.
Commit 166ae5a418 ("btrfs: fix inline compressed read err corruption")
fixed bug #2: compressed inline extents which contained non-zero bytes
might be replaced with zero bytes in some cases. This patch removed an
unhelpful memset from uncompress_inline, but the case where memset is
required was missed.
There is also a memset in the decompression code, but this only covers
decompressed data that is shorter than the ram_bytes from the extent
ref record. This memset doesn't cover the region between the end of the
decompressed data and the end of the page. It has also moved around a
few times over the years, so there's no single patch to refer to.
This patch fixes bug #3: compressed inline extents followed by a hole
and more extents could get non-zero data in the hole as they were read
(i.e. bug #3 is the same as bug #1, but s/uncompressed/compressed/).
The fix is the same: zero out the hole in the compressed case too,
by putting a memset back in uncompress_inline, but this time with
correct parameters.
The last and oldest bug, bug #0, is the cause of the offending inline
extent/hole/extent pattern. Bug #0 is a subtle and mostly-harmless quirk
of behavior somewhere in the btrfs write code. In a few special cases,
an inline extent and hole are allowed to persist where they normally
would be combined with later extents in the file.
A fast reproducer for bug #0 is presented below. A few offending extents
are also created in the wild during large rsync transfers with the -S
flag. A Linux kernel build (git checkout; make allyesconfig; make -j8)
will produce a handful of offending files as well. Once an offending
file is created, it can present different content to userspace each
time it is read.
Bug #0 is at least 4 and possibly 8 years old. I verified every vX.Y
kernel back to v3.5 has this behavior. There are fossil records of this
bug's effects in commits all the way back to v2.6.32. I have no reason
to believe bug #0 wasn't present at the beginning of btrfs compression
support in v2.6.29, but I can't easily test kernels that old to be sure.
It is not clear whether bug #0 is worth fixing. A fix would likely
require injecting extra reads into currently write-only paths, and most
of the exceptional cases caused by bug #0 are already handled now.
Whether we like them or not, bug #0's inline extents followed by holes
are part of the btrfs de-facto disk format now, and we need to be able
to read them without data corruption or an infoleak. So enough about
bug #0, let's get back to bug #3 (this patch).
An example of on-disk structure leading to data corruption found in
the wild:
item 61 key (606890 INODE_ITEM 0) itemoff 9662 itemsize 160
inode generation 50 transid 50 size 47424 nbytes 49141
block group 0 mode 100644 links 1 uid 0 gid 0
rdev 0 flags 0x0(none)
item 62 key (606890 INODE_REF 603050) itemoff 9642 itemsize 20
inode ref index 3 namelen 10 name: DB_File.so
item 63 key (606890 EXTENT_DATA 0) itemoff 8280 itemsize 1362
inline extent data size 1341 ram 4085 compress(zlib)
item 64 key (606890 EXTENT_DATA 4096) itemoff 8227 itemsize 53
extent data disk byte 5367308288 nr 20480
extent data offset 0 nr 45056 ram 45056
extent compression(zlib)
Different data appears in userspace during each read of the 11 bytes
between 4085 and 4096. The extent in item 63 is not long enough to
fill the first page of the file, so a memset is required to fill the
space between item 63 (ending at 4085) and item 64 (beginning at 4096)
with zero.
Here is a reproducer from Liu Bo, which demonstrates another method
of creating the same inline extent and hole pattern:
Using 'page_poison=on' kernel command line (or enable
CONFIG_PAGE_POISONING) run the following:
# touch foo
# chattr +c foo
# xfs_io -f -c "pwrite -W 0 1000" foo
# xfs_io -f -c "falloc 4 8188" foo
# od -x foo
# echo 3 >/proc/sys/vm/drop_caches
# od -x foo
This produce the following on my box:
Correct output: file contains 1000 data bytes followed
by zeros:
0000000 cdcd cdcd cdcd cdcd cdcd cdcd cdcd cdcd
*
0001740 cdcd cdcd cdcd cdcd 0000 0000 0000 0000
0001760 0000 0000 0000 0000 0000 0000 0000 0000
*
0020000
Actual output: the data after the first 1000 bytes
will be different each run:
0000000 cdcd cdcd cdcd cdcd cdcd cdcd cdcd cdcd
*
0001740 cdcd cdcd cdcd cdcd 6c63 7400 635f 006d

In some situations, the firmware will return 0 for autoneg supported
speed. This may happen if the firmware detects no SFP module, for
example. The driver should ignore this so that we don't end up with
an invalid autoneg setting with nothing advertised. When SFP module
is inserted, we'll get the updated settings from firmware at that time.

From: "tang.junhui" <tang.junhui(a)zte.com.cn>
[ Upstream commit c157313791a999646901b3e3c6888514ebc36d62 ]
Currently, Cache missed IOs are identified by s->cache_miss, but actually,
there are many situations that missed IOs are not assigned a value for
s->cache_miss in cached_dev_cache_miss(), for example, a bypassed IO
(s->iop.bypass = 1), or the cache_bio allocate failed. In these situations,
it will go to out_put or out_submit, and s->cache_miss is null, which leads
bch_mark_cache_accounting() to treat this IO as a hit IO.

From: Liang Chen <liangchen.linux(a)gmail.com>
[ Upstream commit 330a4db89d39a6b43f36da16824eaa7a7509d34d ]
mutex_destroy does nothing most of time, but it's better to call
it to make the code future proof and it also has some meaning
for like mutex debug.
As Coly pointed out in a previous review, bcache_exit() may not be
able to handle all the references properly if userspace registers
cache and backing devices right before bch_debug_init runs and
bch_debug_init failes later. So not exposing userspace interface
until everything is ready to avoid that issue.

MD's rdev_set_badblocks() expects that badblocks_set() returns 1 if
badblocks are disabled, otherwise, rdev_set_badblocks() will record
superblock changes and return success in that case and md will fail to
report an IO error which it should.

When the user sets count to zero the string buffer would remain

own stack data, potentially leading to an info leak. In addition
to that, the string might be not terminated properly when the

Subject: arm64: prevent regressions in compressed kernel image size when upgrading to binutils 2.27
From: Nick Desaulniers <ndesaulniers(a)google.com>
[ Upstream commit fd9dde6abcb9bfe6c6bee48834e157999f113971 ]
Upon upgrading to binutils 2.27, we found that our lz4 and gzip
compressed kernel images were significantly larger, resulting is 10ms
boot time regressions.
As noted by Rahul:
"aarch64 binaries uses RELA relocations, where each relocation entry
includes an addend value. This is similar to x86_64. On x86_64, the
addend values are also stored at the relocation offset for relative
relocations. This is an optimization: in the case where code does not
need to be relocated, the loader can simply skip processing relative
relocations. In binutils-2.25, both bfd and gold linkers did this for
x86_64, but only the gold linker did this for aarch64. The kernel build
here is using the bfd linker, which stored zeroes at the relocation
offsets for relative relocations. Since a set of zeroes compresses
better than a set of non-zero addend values, this behavior was resulting
in much better lz4 compression.
The bfd linker in binutils-2.27 is now storing the actual addend values
at the relocation offsets. The behavior is now consistent with what it
does for x86_64 and what gold linker does for both architectures. The
change happened in this upstream commit:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=1f56df9d0d5ad8980…
Since a bunch of zeroes got replaced by non-zero addend values, we see
the side effect of lz4 compressed image being a bit bigger.
To get the old behavior from the bfd linker, "--no-apply-dynamic-relocs"
flag can be used:
$ LDFLAGS="--no-apply-dynamic-relocs" make
With this flag, the compressed image size is back to what it was with
binutils-2.25.
If the kernel is using ASLR, there aren't additional runtime costs to
--no-apply-dynamic-relocs, as the relocations will need to be applied
again anyway after the kernel is relocated to a random address.
If the kernel is not using ASLR, then presumably the current default
behavior of the linker is better. Since the static linker performed the
dynamic relocs, and the kernel is not moved to a different address at
load time, it can skip applying the relocations all over again."
Some measurements:
$ ld -v
GNU ld (binutils-2.25-f3d35cf6) 2.25.51.20141117
^
$ ls -l vmlinux
-rwxr-x--- 1 ndesaulniers eng 300652760 Oct 26 11:57 vmlinux

$ ls -l Image.lz4-dtb
-rw-r----- 1 ndesaulniers eng 16932466 Oct 26 12:06 Image.lz4-dtb
By Siqi's measurement w/ gzip:
binutils 2.27 with this patch (with --no-apply-dynamic-relocs):
Image 41535488
Image.gz 13404067
binutils 2.27 without this patch (without --no-apply-dynamic-relocs):
Image 41535488
Image.gz 14125516
Any compression scheme should be able to get better results from the
longer runs of zeros, not just GZIP and LZ4.
10ms boot time savings isn't anything to get excited about, but users of
arm64+compression+bfd-2.27 should not have to pay a penalty for no
runtime improvement.

When the PMU driver is built as a module, the perf expects the
pmu->module to be valid, so that the driver is prevented from
being unloaded while it is in use. Fix the CCN pmu driver to
fill in this field.

From: Marc Dionne <marc.dionne(a)auristor.com>
[ Upstream commit ab94f5d0dd6fd82e7eeca5e7c8096eaea0a0261f ]
The inode timestamps should be set from the client time
in the status received from the server, rather than the
server time which is meant for internal server use.
Set AFS_SET_MTIME and populate the mtime for operations
that take an input status, such as file/dir creation
and StoreData. If an input time is not provided the
server will set the vnode times based on the current server
time.
In a situation where the server has some skew with the
client, this could lead to the client seeing a timestamp
in the future for a file that it just created or wrote.

From: David Howells <dhowells(a)redhat.com>
[ Upstream commit 1157f153f37a8586765034470e4f00a4a6c4ce6f ]
When we are given an invalid operation ID, we should abort that with
RXGEN_OPCODE rather than RX_INVALID_OPERATION.
Also map RXGEN_OPCODE to -ENOTSUPP.

[ Upstream commit 146a1192783697810b63a1e41c4d59fc93387340 ]
afs_fs_store_data() works out of the size of the write it's going to make,
but it uses 32-bit unsigned subtraction in one place that gets
automatically cast to loff_t.
However, if to < offset, then the number goes negative, but as the result
isn't signed, this doesn't get sign-extended to 64-bits when placed in a
loff_t.
Fix by casting the operands to loff_t.

From: David Howells <dhowells(a)redhat.com>
[ Upstream commit 7286a35e893176169b09715096a4aca557e2ccd2 ]
Fix afs_kill_pages() in two ways:
(1) If a writeback has been partially flushed, then if we try and kill the
pages it contains, some of them may no longer be undergoing writeback
and end_page_writeback() will assert.
Fix this by checking to see whether the page in question is actually
undergoing writeback before ending that writeback.
(2) The loop that scans for pages to kill doesn't increase the first page
index, and so the loop may not terminate, but it will try to process
the same pages over and over again.
Fix this by increasing the first page index to one after the last page
we processed.

Subject: afs: Fix abort on signal while waiting for call completion
From: David Howells <dhowells(a)redhat.com>
[ Upstream commit 954cd6dc02a65065aecb7150962c0870c5b0e322 ]
Fix the way in which a call that's in progress and being waited for is
aborted in the case that EINTR is detected. We should be sending
RX_USER_ABORT rather than RX_CALL_DEAD as the abort code.
Note that since the only two ways out of the loop are if the call completes
or if a signal happens, the kill-the-call clause after the loop has
finished can only happen in the case of EINTR. This means that we only
have one abort case to deal with, not two, and the "KWC" case can never
happen and so can be deleted.
Note further that simply aborting the call isn't necessarily the best thing
here since at this point: the request has been entirely sent and it's
likely the server will do the operation anyway - whether we abort it or
not. In future, we should punt the handling of the remainder of the call
off to a background thread.

From: Marc Dionne <marc.dionne(a)auristor.com>
[ Upstream commit bcd89270d93b7edebb5de5e5e7dca1a77a33496e ]
Servers may send a callback array that is the same size as
the FID array, or an empty array. If the callback count is
0, the code would attempt to read (fid_count * 12) bytes of
data, which would fail and result in an unmarshalling error.
This would lead to stale data for remotely modified files
or directories.
Store the callback array size in the internal afs_call
structure and use that to determine the amount of data to
read.

Mode bits for an afs file should not be enforced in the usual
way.
For files, the absence of user bits can restrict file access
with respect to what is granted by the server.
These bits apply regardless of the owner or the current uid; the
rest of the mode bits (group, other) are ignored.

From: Chuck Lever <chuck.lever(a)oracle.com>
[ Upstream commit 8f66b1a529047a972cb9602a919c53a95f3d7a2b ]
In current kernels, waiting in xprt_release appears to be safe to
do. I had erroneously believed that for ASYNC RPCs, waiting of any
kind in xprt_release->xprt_rdma_free would result in deadlock. I've
done injection testing and consulted with Trond to confirm that
waiting in the RPC release path is safe.
For the very few times where RPC resources haven't yet been released
earlier by the reply handler, it is safe to wait synchronously in
xprt_rdma_free for invalidation rather than defering it to MR
recovery.
Note: When the QP is error state, posting a LocalInvalidate should
flush and mark the MR as bad. There is no way the remote HCA can
access that MR via a QP in error state, so it is effectively already
inaccessible and thus safe for the Upper Layer to access. The next
time the MR is used it should be recognized and cleaned up properly
by frwr_op_map.

Subject: xfs: truncate pagecache before writeback in xfs_setattr_size()
From: Eryu Guan <eguan(a)redhat.com>
[ Upstream commit 350976ae21873b0d36584ea005076356431b8f79 ]
On truncate down, if new size is not block size aligned, we zero the
rest of block to avoid exposing stale data to user, and
iomap_truncate_page() skips zeroing if the range is already in
unwritten state or a hole. Then we writeback from on-disk i_size to
the new size if this range hasn't been written to disk yet, and
truncate page cache beyond new EOF and set in-core i_size.
The problem is that we could write data between di_size and newsize
before removing the page cache beyond newsize, as the extents may
still be in unwritten state right after a buffer write. As such, the
page of data that newsize lies in has not been zeroed by page cache
invalidation before it is written, and xfs_do_writepage() hasn't
triggered it's "zero data beyond EOF" case because we haven't
updated in-core i_size yet. Then a subsequent mmap read could see
non-zeros past EOF.
I occasionally see this in fsx runs in fstests generic/112, a
simplified fsx operation sequence is like (assuming 4k block size
xfs):
fallocate 0x0 0x1000 0x0 keep_size
write 0x0 0x1000 0x0
truncate 0x0 0x800 0x1000
punch_hole 0x0 0x800 0x800
mapread 0x0 0x800 0x800
where fallocate allocates unwritten extent but doesn't update
i_size, buffer write populates the page cache and extent is still
unwritten, truncate skips zeroing page past new EOF and writes the
page to disk, punch_hole invalidates the page cache, at last mapread
reads the block back and sees non-zero beyond EOF.
Fix it by moving truncate_setsize() to before writeback so the page
cache invalidation zeros the partial page at the new EOF. This also
triggers "zero data beyond EOF" in xfs_do_writepage() at writeback
time, because newsize has been set and page straddles the newsize.
Also fixed the wrong 'end' param of filemap_write_and_wait_range()
call while we're at it, the 'end' is inclusive and should be
'newsize - 1'.

[ Upstream commit ed438b476b611c67089760037139f93ea8ed41d5 ]
For an XFS_IGET_INCORE iget operation, if the inode isn't in the cache,
return ENODATA so that we don't confuse it with the pre-existing ENOENT
cases (inode is in cache, but freed).

Subject: xfs: fix log block underflow during recovery cycle verification
From: Brian Foster <bfoster(a)redhat.com>
[ Upstream commit 9f2a4505800607e537e9dd9dea4f55c4b0c30c7a ]
It is possible for mkfs to format very small filesystems with too
small of an internal log with respect to the various minimum size
and block count requirements. If this occurs when the log happens to
be smaller than the scan window used for cycle verification and the
scan wraps the end of the log, the start_blk calculation in
xlog_find_head() underflows and leads to an attempt to scan an
invalid range of log blocks. This results in log recovery failure
and a failed mount.
Since there may be filesystems out in the wild with this kind of
geometry, we cannot simply refuse to mount. Instead, cap the scan
window for cycle verification to the size of the physical log. This
ensures that the cycle verification proceeds as expected when the
scan wraps the end of the log.

From: Christoph Hellwig <hch(a)lst.de>
[ Upstream commit 5e422f5e4fd71d18bc6b851eeb3864477b3d842e ]
There was one spot in xfs_bmap_add_extent_unwritten_real that didn't use the
passed in new extent state but always converted to normal, leading to wrong
behavior when converting from normal to unwritten.
Only found by code inspection, it seems like this code path to move partial
extent from written to unwritten while merging it with the next extent is
rarely exercised.

The driver may sleep under a spinlock, and the function call path is:
vt6655_suspend (acquire the spinlock)
pci_set_power_state
__pci_start_power_transition (drivers/pci/pci.c)
msleep --> may sleep
To fix it, pci_set_power_state is called without having a spinlock.

Subject: thermal/drivers/step_wise: Fix temperature regulation misbehavior
From: Daniel Lezcano <daniel.lezcano(a)linaro.org>
[ Upstream commit 07209fcf33542c1ff1e29df2dbdf8f29cdaacb10 ]
There is a particular situation when the cooling device is cpufreq and the heat
dissipation is not efficient enough where the temperature increases little by
little until reaching the critical threshold and leading to a SoC reset.
The behavior is reproducible on a hikey6220 with bad heat dissipation (eg.
stacked with other boards).
Running a simple C program doing while(1); for each CPU of the SoC makes the
temperature to reach the passive regulation trip point and ends up to the
maximum allowed temperature followed by a reset.
This issue has been also reported by running the libhugetlbfs test suite.
What is observed is a ping pong between two cpu frequencies, 1.2GHz and 900MHz
while the temperature continues to grow.
It appears the step wise governor calls get_target_state() the first time with
the throttle set to true and the trend to 'raising'. The code selects logically
the next state, so the cpu frequency decreases from 1.2GHz to 900MHz, so far so
good. The temperature decreases immediately but still stays greater than the
trip point, then get_target_state() is called again, this time with the
throttle set to true *and* the trend to 'dropping'. From there the algorithm
assumes we have to step down the state and the cpu frequency jumps back to
1.2GHz. But the temperature is still higher than the trip point, so
get_target_state() is called with throttle=1 and trend='raising' again, we jump
to 900MHz, then get_target_state() is called with throttle=1 and
trend='dropping', we jump to 1.2GHz, etc ... but the temperature does not
stabilizes and continues to increase.

[ 238.134679] thermal cooling_device0: cur_state=0
[ 238.134690] thermal cooling_device0: old_target=0, target=1
In this situation the temperature continues to increase while the trend is
oscillating between 'dropping' and 'raising'. We need to keep the current state
untouched if the throttle is set, so the temperature can decrease or a higher
state could be selected, thus preventing this oscillation.
Keeping the next_target untouched when 'throttle' is true at 'dropping' time
fixes the issue.
The following traces show the governor does not change the next state if
trend==2 (dropping) and throttle==1.

After a while, if the temperature continues to increase, the next state becomes
2 which is 720MHz on the hikey. That results in the temperature stabilizing
around the trip point.

IOW, this change is needed to keep the state for a cooling device if the
temperature trend is oscillating while the temperature increases slightly.
Without this change, the situation above leads to a catastrophic crash by a
hardware reset on hikey. This issue has been reported to happen on an OMAP
dra7xx also.

Subject: target/iscsi: Detect conn_cmd_list corruption early
From: Bart Van Assche <bart.vanassche(a)wdc.com>
[ Upstream commit 6eaf69e4ec075f5af236c0c89f75639a195db904 ]
Certain behavior of the initiator can cause the target driver to
send both a reject and a SCSI response. If that happens two
target_put_sess_cmd() calls will occur without the command having
been removed from conn_cmd_list. In other words, conn_cmd_list
will get corrupted once the freed memory is reused. Although the
Linux kernel can detect list corruption if list debugging is
enabled, in this case the context in which list corruption is
detected is not related to the context that caused list corruption.
Hence add WARN_ON() statements that report the context that is
causing list corruption.

From: Matthias Brugger <matthias.bgg(a)gmail.com>
[ Upstream commit fb2c1934f30577756e55e24e8870b45c78da3bc2 ]
When compiling using sparse, we got the following error:
drivers/soc/mediatek/mtk-pmic-wrap.c:686:25: error: dubious one-bit signed bitfield
Changing the data type to unsigned fixes this.

The tty-driver open routine is mandatory, but the serdev
tty-port-controller implementation did not treat it as such and would
instead fall back to calling tty_port_open() directly.

The scsi_debug driver incorrectly suggests there is an error with the
SCSI WRITE SAME command when the number_of_logical_blocks is greater
than 1. It will also suggest there is an error when NDOB
(no data-out buffer) is set and the number_of_logical_blocks is
greater than 0. Both are valid, fix.

[ Upstream commit dfb2e6f46b3074eb85203d8f0888b71ec1c2e37a ]
This patch cleans up a lot of warnings when unloading the driver.
A current example of the stack trace starts with:
[ 142.570715] sysfs group 'power' not found for kobject 'port-5:0'
There can be hundreds of these messages during a driver unload.
I am resubmitting this patch on behalf of Martin Wilck with his
permission.
His original patch can be found here:
https://www.spinics.net/lists/linux-scsi/msg102085.html
This patch did not help until Hannes's
commit 9441284fbc39 ("scsi-fixup-kernel-warning-during-rmmod")
was applied to the kernel.

[ 1063.797134] [<ffffffffa036ebcc>] hpsa_free_sas_port+0x3c/0x70 [hpsa]
This is caused by the fact that host device hostX is deleted before the
SAS transport devices hostX/port-a:b.
This patch fixes this by reverting the order of device deletions.

Original patch description from Martin:
--------------------------------------
When the hpsa module is unloaded using rmmod, dangling
symlinks remain under /sys/class/sas_phy. Fix this by
calling sas_phy_delete() rather than sas_phy_free (which,
according to comments, should not be called for PHYs that
have been set up successfully, anyway).

Subject: scsi: hisi_sas: fix the risk of freeing slot twice
From: Xiaofei Tan <tanxiaofei(a)huawei.com>
[ Upstream commit 6ba0fbc35aa9f3bc8c12be3b4047055c9ce2ac92 ]
The function hisi_sas_slot_task_free() is used to free the slot and do
tidy-up of LLDD resources. The LLDD generally should know the state of
a slot and decide when to free it, and it should only be done once.
For some scenarios, we really don't know the state, like when TMF
timeout. In this case, we check task->lldd_task before calling
hisi_sas_slot_task_free().
However, we may miss some scenarios when we should also check
task->lldd_task, and it is not SMP safe to check task->lldd_task as we
don't protect it within spin lock.
This patch is to fix this risk of freeing slot twice, as follows:
1. Check task->lldd_task in the hisi_sas_slot_task_free(), and give
up freeing of this time if task->lldd_task is NULL.
2. Set slot->buf to NULL after it is freed.

Subject: scsi: bfa: integer overflow in debugfs
From: Dan Carpenter <dan.carpenter(a)oracle.com>
[ Upstream commit 3e351275655d3c84dc28abf170def9786db5176d ]
We could allocate less memory than intended because we do:
bfad->regdata = kzalloc(len << 2, GFP_KERNEL);
The shift can overflow leading to a crash. This is debugfs code so the
impact is very small. I fixed the network version of this in March with
commit 13e2d5187f6b ("bna: integer overflow bug in debugfs").

Subject: scsi: aacraid: use timespec64 instead of timeval
From: Arnd Bergmann <arnd(a)arndb.de>
[ Upstream commit 820f188659122602ab217dd80cfa32b3ac0c55c0 ]
aacraid passes the current time to the firmware in one of two ways,
either as year/month/day/... or as 32-bit unsigned seconds.
The first one is broken on 32-bit architectures as it cannot go past
year 2038. Using timespec64 here makes it behave properly on both 32-bit
and 64-bit architectures, and avoids relying on signed integer overflow
to pass times into the second interface.
The interface used in aac_send_hosttime() however is still problematic
in year 2106 when 32-bit seconds overflow. Hopefully we don't have to
worry about aacraid by that time.

Subject: RDMA/cma: Avoid triggering undefined behavior
From: Bart Van Assche <bart.vanassche(a)wdc.com>
[ Upstream commit c0b64f58e8d49570aa9ee55d880f92c20ff0166b ]
According to the C standard the behavior of computations with
integer operands is as follows:
* A computation involving unsigned operands can never overflow,
because a result that cannot be represented by the resulting
unsigned integer type is reduced modulo the number that is one
greater than the largest value that can be represented by the
resulting type.
* The behavior for signed integer underflow and overflow is
undefined.
Hence only use unsigned integers when checking for integer
overflow.
This patch is what I came up with after having analyzed the
following smatch warnings:
drivers/infiniband/core/cma.c:3448: cma_resolve_ib_udp() warn: signed overflow undefined. 'offset + conn_param->private_data_len < conn_param->private_data_len'

Subject: raid5: Set R5_Expanded on parity devices as well as data.
From: NeilBrown <neilb(a)suse.com>
[ Upstream commit 235b6003fb28f0dd8e7ed8fbdb088bb548291766 ]
When reshaping a fully degraded raid5/raid6 to a larger
nubmer of devices, the new device(s) are not in-sync
and so that can make the newly grown stripe appear to be
"failed".
To avoid this, we set the R5_Expanded flag to say "Even though
this device is not fully in-sync, this block is safe so
don't treat the device as failed for this stripe".
This flag is set for data devices, not not for parity devices.
Consequently, if you have a RAID6 with two devices that are partly
recovered and a spare, and start a reshape to include the spare,
then when the reshape gets past the point where the recovery was
up to, it will think the stripes are failed and will get into
an infinite loop, failing to make progress.
So when contructing parity on an EXPAND_READY stripe,
set R5_Expanded.

Subject: powerpc/pseries/vio: Dispose of virq mapping on vdevice unregister
From: Tyrel Datwyler <tyreld(a)linux.vnet.ibm.com>
[ Upstream commit b8f89fea599d91e674497aad572613eb63181f31 ]
When a vdevice is DLPAR removed from the system the vio subsystem
doesn't bother unmapping the virq from the irq_domain. As a result we
have a virq mapped to a hardware irq that is no longer valid for the
irq_domain. A side effect is that we are left with /proc/irq/<irq#>
affinity entries, and attempts to modify the smp_affinity of the irq
will fail.
In the following observed example the kernel log is spammed by
ics_rtas_set_affinity errors after the removal of a VSCSI adapter.
This is a result of irqbalance trying to adjust the affinity every 10
seconds.
rpadlpar_io: slot U8408.E8E.10A7ACV-V5-C25 removed
ics_rtas_set_affinity: ibm,set-xive irq=655385 returns -3
ics_rtas_set_affinity: ibm,set-xive irq=655385 returns -3
This patch fixes the issue by calling irq_dispose_mapping() on the
virq of the viodev on unregister.

The call to /proc/cpuinfo in turn calls cpufreq_quick_get() which
returns the last frequency requested by the kernel, but may not
reflect the actual frequency the processor is running at. This patch
makes a call to cpufreq_get() instead which returns the current

[ Upstream commit 05c14c03138532a3cb2aa29c2960445c8753343b ]
In the hv-24x7 code there is a function memord() which tries to
implement a sort function return -1, 0, 1. However one of the
conditions is incorrect, such that it can never be true, because we
will have already returned.
I don't believe there is a bug in practice though, because the
comparisons are an optimisation prior to calling memcmp().
Fix it by swapping the second comparision, so it can be true.

Subject: powerpc/opal: Fix EBUSY bug in acquiring tokens
From: "William A. Kennington III" <wak(a)google.com>
[ Upstream commit 71e24d7731a2903b1ae2bba2b2971c654d9c2aa6 ]
The current code checks the completion map to look for the first token
that is complete. In some cases, a completion can come in but the
token can still be on lease to the caller processing the completion.
If this completed but unreleased token is the first token found in the
bitmap by another tasks trying to acquire a token, then the
__test_and_set_bit call will fail since the token will still be on
lease. The acquisition will then fail with an EBUSY.
This patch reorganizes the acquisition code to look at the
opal_async_token_map for an unleased token. If the token has no lease
it must have no outstanding completions so we should never see an
EBUSY, unless we have leased out too many tokens. Since
opal_async_get_token_inrerruptible is protected by a semaphore, we
will practically never see EBUSY anymore.

Subject: PM / s2idle: Clear the events_check_enabled flag
From: Rajat Jain <rajatja(a)google.com>
[ Upstream commit 95b982b45122c57da2ee0b46cce70775e1d987af ]
Problem: This flag does not get cleared currently in the suspend or
resume path in the following cases:
* In case some driver's suspend routine returns an error.
* Successful s2idle case
* etc?
Why is this a problem: What happens is that the next suspend attempt
could fail even though the user did not enable the flag by writing to
/sys/power/wakeup_count. This is 1 use case how the issue can be seen
(but similar use case with driver suspend failure can be thought of):
1. Read /sys/power/wakeup_count
2. echo count > /sys/power/wakeup_count
3. echo freeze > /sys/power/wakeup_count
4. Let the system suspend, and wakeup the system using some wake source
that calls pm_wakeup_event() e.g. power button or something.
5. Note that the combined wakeup count would be incremented due
to the pm_wakeup_event() in the resume path.
6. After resuming the events_check_enabled flag is still set.
At this point if the user attempts to freeze again (without writing to
/sys/power/wakeup_count), the suspend would fail even though there has
been no wake event since the past resume.
Address that by clearing the flag just before a resume is completed,
so that it is always cleared for the corner cases mentioned above.

Source code review for a specific software refactoring showed the need
for another correction because the error code "-1" was returned so far
if a call of the function "sony_call_snc_handle" failed here.
Thus assign the return value from these two function calls also to
the variable "err" and provide it in case of a failure.

[ Upstream commit 6cc8cbbc8868033f279b63e98b26b75eaa0006ab ]
For PUNIT device, ISPDRIVER_IPC and GTDDRIVER_IPC resources are not
mandatory. So when PMC IPC driver creates a PUNIT device, if these
resources are not available then it creates dummy resource entries for
these missing resources. But during PUNIT device probe, doing ioremap on
these dummy resources generates following warning messages.
intel_punit_ipc: can't request region for resource [mem 0x00000000]
intel_punit_ipc: can't request region for resource [mem 0x00000000]
intel_punit_ipc: can't request region for resource [mem 0x00000000]
intel_punit_ipc: can't request region for resource [mem 0x00000000]
This patch fixes this issue by adding extra check for resource size
before performing ioremap operation.

From: Osama Khan <osama.khan(a)ericsson.com>
[ Upstream commit 163ca80013aafb6dc9cb295de3db7aeab9ab43f8 ]
Added support for HP ProBook 440 G4 laptops by including the accelerometer
orientation quirk for that device. Testing was performed based on the
axis orientation guidelines here:
https://www.kernel.org/doc/Documentation/misc-devices/lis3lv02d
which states "If the left side is elevated, X increases (becomes positive)".
When tested, on lifting the left edge, x values became increasingly negative
thus indicating an inverted x-axis on the installed lis3lv02d chip.
This was compensated by adding an entry for this device in hp_accel.c
specifying the quirk as x_inverted. The patch was tested on a
ProBook 440 G4 device and x-axis as well as y and z-axis values are now
generated as per spec.

From: Linus Walleij <linus.walleij(a)linaro.org>
[ Upstream commit 1c363531dd814dc4fe10865722bf6b0f72ce4673 ]
The build robot is complaining on Blackfin:
drivers/pinctrl/pinctrl-adi2.c: In function 'port_setup':
>> drivers/pinctrl/pinctrl-adi2.c:221:21: error: dereferencing
pointer to incomplete type 'struct gpio_port_t'

if (readl(®s->invert_set) & pintbit)
^~
It seems the driver need to include <asm/gpio.h> and <asm/irq.h>
to compile.
The Blackfin architecture was re-defining the Kconfig
PINCTRL symbol which is not OK, so replaced this with
PINCTRL_BLACKFIN_ADI2 which selects PINCTRL and PINCTRL_ADI2
just like most arches do.
Further, the old GPIO driver symbol GPIO_ADI was possible to
select at the same time as selecting PINCTRL. This was not
working because the arch-local <asm/gpio.h> header contains
an explicit #ifndef PINCTRL clause making compilation break
if you combine them. The same is true for DEBUG_MMRS.
Make sure the ADI2 pinctrl driver is not selected at the same
time as the old GPIO implementation. (This should be converted
to use gpiolib or pincontrol and move to drivers/...) Also make
sure the old GPIO_ADI driver or DEBUG_MMRS is not selected at
the same time as the new PINCTRL implementation, and only make

have it.
This way it is still possible to add e.g. I2C-based pin
control expanders on the Blackfin.

Subject: PCI/PME: Handle invalid data when reading Root Status
From: Qiang <zhengqiang10(a)huawei.com>
[ Upstream commit 3ad3f8ce50914288731a3018b27ee44ab803e170 ]
PCIe PME and native hotplug share the same interrupt number, so hotplug
interrupts are also processed by PME. In some cases, e.g., a Link Down
interrupt, a device may be present but unreachable, so when we try to
read its Root Status register, the read fails and we get all ones data
(0xffffffff).
Previously, we interpreted that data as PCI_EXP_RTSTA_PME being set, i.e.,
"some device has asserted PME," so we scheduled pcie_pme_work_fn(). This
caused an infinite loop because pcie_pme_work_fn() tried to handle PME
requests until PCI_EXP_RTSTA_PME is cleared, but with the link down,
PCI_EXP_RTSTA_PME can't be cleared.
Check for the invalid 0xffffffff data everywhere we read the Root Status
register.
1469d17dd341 ("PCI: pciehp: Handle invalid data when reading from
non-existent devices") added similar checks in the hotplug driver.

Subject: PCI: Do not allocate more buses than available in parent
From: Mika Westerberg <mika.westerberg(a)linux.intel.com>
[ Upstream commit a20c7f36bd3d20d245616ae223bb9d05dfb6f050 ]
One can ask more buses to be reserved for hotplug bridges by passing
pci=hpbussize=N in the kernel command line. If the parent bus does not
have enough bus space available we incorrectly create child bus with the
requested number of subordinate buses.
In the example below hpbussize is set to one more than we have available
buses in the root port:
pci 0000:07:00.0: [8086:1578] type 01 class 0x060400
pci 0000:07:00.0: scanning [bus 00-00] behind bridge, pass 0
pci 0000:07:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring
pci 0000:07:00.0: scanning [bus 00-00] behind bridge, pass 1
pci_bus 0000:08: busn_res: can not insert [bus 08-ff] under [bus 07-3f] (conflicts with (null) [bus 07-3f])
pci_bus 0000:08: scanning bus

pci_bus 0000:0a: bus scan returning with max=40
pci_bus 0000:0a: busn_res: [bus 0a-ff] end is updated to 40
pci_bus 0000:0a: [bus 0a-40] partially hidden behind bridge 0000:07 [bus 07-3f]
pci_bus 0000:08: bus scan returning with max=40
pci_bus 0000:08: busn_res: [bus 08-ff] end is updated to 40
Instead of allowing this, limit the subordinate number to be less than or
equal the maximum subordinate number allocated for the parent bus (if it
has any).

Subject: PCI: Detach driver before procfs & sysfs teardown on device remove
From: Alex Williamson <alex.williamson(a)redhat.com>
[ Upstream commit 16b6c8bb687cc3bec914de09061fcb8411951fda ]
When removing a device, for example a VF being removed due to SR-IOV
teardown, a "soft" hot-unplug via 'echo 1 > remove' in sysfs, or an actual
hot-unplug, we first remove the procfs and sysfs attributes for the device
before attempting to release the device from any driver bound to it.
Unbinding the driver from the device can take time. The device might need
to write out data or it might be actively in use. If it's in use by
userspace through a vfio driver, the unbind might block until the user
releases the device. This leads to a potentially non-trivial amount of
time where the device exists, but we've torn down the interfaces that
userspace uses to examine devices, for instance lspci might generate this
sort of error:
pcilib: Cannot open /sys/bus/pci/devices/0000:01:0a.3/config
lspci: Unable to read the standard configuration space header of device 0000:01:0a.3
We don't seem to have any dependence on this teardown ordering in the
kernel, so let's unbind the driver first, which is also more symmetric with
the instantiation of the device in pci_bus_add_device().

[ Upstream commit 564883bb4dc1a4f3cba6344e77743175694b0761 ]
If one buffer had been recieved to stack, driver will alloc a new buffer,
map the buffer to device and replace the old buffer. When map fail, should
only free the new alloced buffer, but not free all buffers in the ring.

[ Upstream commit 7036d26f328f12a323069eb16d965055b4cb3795 ]
The SC bits of TX BD mean switch control. For this area, value 0
indicates no switch control, the packet is routed according to the
forwarding table. Value 1 indicates that the packet is transmitted
to the network bypassing the forwarding table.
As HNS3 driver need support VF later, VF conmunicate with its own
PF need forwarding table. This patch sets SC bits of TX BD 0 and use
forwarding table.

fabric port 0 TX is disabled during probe. (Write of LAN9303_MAC_TX_CFG_0
in lan9303_disable_processing_port().)
In that situation the switch fabric seem to receive frames, because the ALR
is learning addresses. But no frames are transmitted on any of the ports.
In our system lan9303_probe() is called twice, first time
dsa_register_switch() return -EPROBE_DEFER. As an experiment, modified the
code to skip writing LAN9303_MAC_TX_CFG_0, port 0 during the first probe.
Then the switch works as expected.
Resolve the problem by not calling lan9303_disable_processing_port() on
port 0 during probe. Ports 1 and 2 are still disabled.
Although unsatisfying that the exact failure mechanism is not known,
the patch should not cause any harm.

Subject: mtd: spi-nor: stm32-quadspi: Fix uninitialized error return code
From: Geert Uytterhoeven <geert(a)linux-m68k.org>
[ Upstream commit 05521bd3d117704a1458eb4d0c3ae821858658f2 ]
With gcc 4.1.2:
drivers/mtd/spi-nor/stm32-quadspi.c: In function ‘stm32_qspi_tx_poll’:
drivers/mtd/spi-nor/stm32-quadspi.c:230: warning: ‘ret’ may be used uninitialized in this function
Indeed, if stm32_qspi_cmd.len is zero, ret will be uninitialized.
This length is passed from outside the driver using the
spi_nor.{read,write}{,_reg}() callbacks.
Several functions in drivers/mtd/spi-nor/spi-nor.c (e.g. write_enable(),
write_disable(), and erase_chip()) call spi_nor.write_reg() with a zero
length.
Fix this by returning an explicit zero on success.

_calc_vm_trans() does not handle the situation when some of the passed
flags are 0 (which can happen if these VM flags do not make sense for
the architecture). Improve the _calc_vm_trans() macro to return 0 in
such situation. Since all passed flags are constant, this does not add
any runtime overhead.

From: Adam Sampson <ats(a)offog.org>
[ Upstream commit b3168c87c0492661badc3e908f977d79e7738a41 ]
Because the brightness and contrast controls share a register,
usbtv_s_ctrl needs to read the existing values for both controls before
inserting the new value. However, the code accidentally wrote to the
registers (from an uninitialised stack array), rather than reading them.
The user-visible effect of this was that adjusting the brightness would
also set the contrast to a random value, and vice versa -- so it wasn't
possible to correctly adjust the brightness of usbtv's video output.
Tested with an "EasyDAY" UTV007 device.

Subject: macvlan: Only deliver one copy of the frame to the macvlan interface
From: Alexander Duyck <alexander.h.duyck(a)intel.com>
[ Upstream commit dd6b9c2c332b40f142740d1b11fb77c653ff98ea ]
This patch intoduces a slight adjustment for macvlan to address the fact
that in source mode I was seeing two copies of any packet addressed to the
macvlan interface being delivered where there should have been only one.
The issue appears to be that one copy was delivered based on the source MAC
address and then the second copy was being delivered based on the
destination MAC address. To fix it I am just treating a unicast address
match as though it is not a match since source based macvlan isn't supposed
to be matching based on the destination MAC anyway.

Reason is: in the function assigned to net_device_ops->ndo_stop, the steps
for bringing down the interface are done in the wrong order. The step that
notifies the NIC firmware to stop forwarding packets to host is done too
late. Fix it by moving that step to the beginning.

GC can be kicked after it has been shut down when closing the last

Make sure that GC is not triggered while it is not operational.
Also make sure that GC won't be re-activated during exit when

Subject: lightnvm: pblk: fix min size for page mempool
From: Javier González <javier(a)cnexlabs.com>
[ Upstream commit bd432417681a224d9fa4a9d43be7d4edc82135b2 ]
pblk uses an internal page mempool for allocating pages on internal
bios. The main two users of this memory pool are partial reads (reads
with some sectors in cache and some on media) and padded writes, which
need to add dummy pages to an existing bio already containing valid
data (and with a large enough bioset allocated). In both cases, the
maximum number of pages per bio is defined by the maximum number of
physical sectors supported by the underlying device.
This patch fixes a bad mempool allocation, where the min_nr of elements
on the pool was fixed (to 16), which is lower than the maximum number
of sectors supported by NVMe (as of the time for this patch). Instead,
use the maximum number of allowed sectors reported by the device.

From: Rakesh Pandit <rakesh(a)tuxera.com>
[ Upstream commit 27b978725d895e704aab44b99242a0514485d798 ]
pblk_line_gc_list seems to had a bug since the introduction of pblk in
getting GC list for a line. In b20ba1bc7 while redesigning the GC
algorithm, the naming for the GC thresholds was altered, but the
values for high_thrs and mid_thrs were not. The result is that when
moving to the GC lists, the mid threshold is never evaluated.

I can use vmxcap tool to observe "EPTP Switching yes" even if EPT is not
exposed to L1.
EPT switching is advertised unconditionally since it is emulated, however,
it can be treated as an extended feature for EPT and it should not be
advertised if EPT itself is not exposed. This patch fixes it.

Subject: icmp: don't fail on fragment reassembly time exceeded
From: Matteo Croce <mcroce(a)redhat.com>
[ Upstream commit 258bbb1b0e594ad5f5652cb526b3c63e6a7fad3d ]
The ICMP implementation currently replies to an ICMP time exceeded message
(type 11) with an ICMP host unreachable message (type 3, code 1).
However, time exceeded messages can either represent "time to live exceeded
in transit" (code 0) or "fragment reassembly time exceeded" (code 1).
Unconditionally replying to "fragment reassembly time exceeded" with
host unreachable messages might cause unjustified connection resets
which are now easily triggered as UFO has been removed, because, in turn,
sending large buffers triggers IP fragmentation.
The issue can be easily reproduced by running a lot of UDP streams
which is likely to trigger IP fragmentation:
# start netserver in the test namespace
ip netns add test
ip netns exec test netserver
# create a VETH pair
ip link add name veth0 type veth peer name veth0 netns test
ip link set veth0 up
ip -n test link set veth0 up

We need to differentiate instead: if fragment reassembly time exceeded
is reported, we need to silently drop the packet,
if time to live exceeded is reported, maintain the current behaviour.
In both cases increment the related error count "icmpInTimeExcds".
While at it, fix a typo in a comment, and convert the if statement
into a switch to mate it more readable.

Subject: IB/mlx4: Fix RSS's QPC attributes assignments
From: Guy Levi <guyle(a)mellanox.com>
[ Upstream commit 108809a0571cd1e1b317c5c083a371e163e1f8f9 ]
In the modify QP handler the base_qpn_udp field in the RSS QPC is
overwrite later by irrelevant value assignment. Hence, ingress packets
which gets to the RSS QP will be steered then to a garbage QPN.
The patch fixes this by skipping the above assignment when a RSS QP is
modified, also, the RSS context's attributes assignments are relocated
just before the context is posted to avoid future issues like this.
Additionally, this patch takes the opportunity to change the code to be
disciplined to the device's manual and assigns the RSS QP context just at
RESET to INIT transition.

When ndo_open and ndo_stop are called RTNL lock should be held.
In this specific case ipoib_ib_dev_open calls the offloaded ndo_open
which re-sets the number of TX queue assuming RTNL lock is held.
Since RTNL lock is not held, RTNL assert will fail.

From: Patel Jay P <jay.p.patel(a)intel.com>
[ Upstream commit 00f9203119dd2774564407c7a67b17d81916298b ]
__subn_get_opa_portinfo stores value returned by hfi1_get_ib_cfg() as
operational vls. hfi1_get_ib_cfg() returns vls_operational field in
hfi1_pportdata. The problem with this is that the value is always equal
to vls_supported field in hfi1_pportdata.
The logic to calculate operational_vls is to set value passed by FM
(in __subn_set_opa_portinfo routine). If no value is passed then
default value is stored in operational_vls.
Field actual_vls_operational is calculated on the basis of buffer
control table. Hence, modifying hfi1_get_ib_cfg() to return
actual_operational_vls when used with HFI1_IB_CFG_OP_VLS parameter

From: Parav Pandit <parav(a)mellanox.com>
[ Upstream commit 39baf10310e6669564a485b55267fae70a4e44ae ]
The IB/core provides address resolution service and invokes callback
handler when address resolve request completes of requester in worker
thread context.
Such caller might allocate or free memory in callback handler
depending on the completion status to make further progress or to
terminate a connection. Most ULPs resolve route which involves
allocating route entry and path record elements in callback event handler.
It has been noticed that WQ_MEM_RECLAIM flag should not be used for
workers that tend to allocate memory in this [1] thread discussion.
In order to mitigate this situation, WQ_MEM_RECLAIM flag was dropped for
other such WQs in this [2] patch.
Similar problem might arise with address resolution path, though its not
yet noticed. The ib_addr workqueue is not memory reclaim path due to its
nature of invoking callback that might allocate memory or don't free any
memory under memory pressure.

The original code only took into consideration the largest header
possible after the IB_BTH_BYTES. This was incorrect, as the largest
possible header size is the largest possible combination of headers we
might run into. The new code accounts for all possible headers in the
largest possible combination and subtracts that from the MTU to make
sure that all packets will fit on the wire.

Subject: GFS2: Take inode off order_write list when setting jdata flag
From: Bob Peterson <rpeterso(a)redhat.com>
[ Upstream commit cc555b09d8c3817aeebda43a14ab67049a5653f7 ]
This patch fixes a deadlock caused when the jdata flag is set for
inodes that are already on the ordered write list. Since it is
on the ordered write list, log_flush calls gfs2_ordered_write which
calls filemap_fdatawrite. But since the inode had the jdata flag
set, that calls gfs2_jdata_writepages, which tries to start a new
transaction. A new transaction cannot be started because it tries
to acquire the log_flush rwsem which is already locked by the log
flush operation.
The bottom line is: We cannot switch an inode from ordered to jdata
until we eliminate any ordered data pages (via log flush) or any
log_flush operation afterward will create the circular dependency
above. So we need to flush the log before setting the diskflags to
switch the file mode, then we need to remove the inode from the
ordered writes list.
Before this patch, the log flush was done for jdata->ordered, but
that's wrong. If we're going from jdata to ordered, we don't need
to call gfs2_log_flush because the call to filemap_fdatawrite will
do it for us:
filemap_fdatawrite() -> __filemap_fdatawrite_range()
__filemap_fdatawrite_range() -> do_writepages()
do_writepages() -> gfs2_jdata_writepages()
gfs2_jdata_writepages() -> gfs2_log_flush()
This patch modifies function do_gfs2_set_flags so that if a file
has its jdata flag set, and it's already on the ordered write list,
the log will be flushed and it will be removed from the list
before setting the flag.

[ Upstream commit ac831a379d34109451b3c41a44a20ee10ecb615f ]
Dan's static analysis says:
drivers/video/fbdev/controlfb.c:560 control_setup()
error: buffer overflow 'control_mac_modes' 20 <= 21
Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22,
which may lead to an out of bounds read when parsing vmode commandline
options.
The bug was introduced in v2.4.5.6, when 2 new modes were added to
macmodes.h, but control_mac_modes[] wasn't updated:
https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.…
Augment control_mac_modes[] with the two new video modes to fix this.

KIQ ring submission is used for register accessing on SRIOV
VF that could happen both in irq enabled and irq disabled cases.
Inversion lock could happen on adev->ring_lru_list_lock, while
this operation is useless and just adds overhead in this use
case.

The used 0x1f mask is only valid for am335x family of SoC, different family
using this type of crossbar might have different number of electable
events. In case of am43xx family 0x3f mask should have been used for
example.
Instead of trying to handle each family's mask, just use u8 type to store
the mux value since the event offsets are aligned to byte offset.

Subject: clk: tegra: Use readl_relaxed_poll_timeout_atomic() in tegra210_clock_init()
From: Nicolin Chen <nicoleotsuka(a)gmail.com>
[ Upstream commit 22ef01a203d27fee8b7694020b7e722db7efd2a7 ]
Below is the call trace of tegra210_init_pllu() function:
start_kernel()
-> time_init()
--> of_clk_init()
---> tegra210_clock_init()
----> tegra210_pll_init()
-----> tegra210_init_pllu()
Because the preemption is disabled in the start_kernel before calling
time_init, tegra210_init_pllu is actually in an atomic context while
it includes a readl_relaxed_poll_timeout that might sleep.
So this patch just changes this readl_relaxed_poll_timeout() to its
atomic version.

From: Chen Zhong <chen.zhong(a)mediatek.com>
[ Upstream commit c955bf3998efa3355790a4d8c82874582f1bc727 ]
Since the previous setup always sets the PLL using crystal 26MHz, this
doesn't always happen in every MediaTek platform. So the patch added
flexibility for assigning extra member for determining the PLL source
clock.

results in system hang. So mark clock cs_atb_syspll as critical to

Subject: btrfs: fix false EIO for missing device
From: Anand Jain <anand.jain(a)oracle.com>
[ Upstream commit 102ed2c5ff932439bbbe74c7bd63e6d5baa9f732 ]
When one of the device is missing, bbio_error() takes care of setting
the error status. And if its only IO that is pending in that stripe, it
fails to check the status of the other IO at %bbio_error before setting
the error %bi_status for the %orig_bio. Fix this by checking if
%bbio->error has exceeded the %bbio->max_errors.
Reproducer as below fdatasync error is seen intermittently.
mount -o degraded /dev/sdc /btrfs
dd status=none if=/dev/zero of=$(mktemp /btrfs/XXX) bs=4096 count=1 conv=fdatasync
dd: fdatasync failed for ‘/btrfs/LSe’: Input/output error
The reason for the intermittences of the problem is because
the following conditions have to be met, which depends on timing:
In btrfs_map_bio()
- the RAID1 the missing device has to be at %dev_nr = 1
In bbio_error()
. before bbio_error() is called the bio of the not-missing
device at %dev_nr = 0 must be completed so that the below
condition is true

From: Nikolay Borisov <nborisov(a)suse.com>
[ Upstream commit 9417ebc8a676487c6ec8825f92fb28f7dbeb5f4b ]
btrfs_udpate_root can fail and it aborts the transaction, the correct
way to handle an aborted transaction is to explicitly end with
btrfs_end_transaction. Even now the code is correct since
btrfs_commit_transaction would handle an aborted transaction but this is
more of an implementation detail. So let's be explicit in handling
failure in btrfs_update_root.
Furthermore btrfs_commit_transaction can also fail and by ignoring it's
return value we could have left the in-memory copy of the root item in
an inconsistent state. So capture the error value which allows us to
correctly revert the RO/RW flags in case of commit failure.

There are checks on fs_info in __btrfs_panic to avoid dereferencing a
null fs_info, however, there is a call to btrfs_crit that may also
dereference a null fs_info. Fix this by adding a check to see if fs_info
is null and only print the s_id if fs_info is non-null.

Subject: Bluetooth: hci_ldisc: Fix another race when closing the tty.
From: Ronald Tschalär <ronald(a)innovation.ch>
[ Upstream commit 0338b1b393ec7910898e8f7b25b3bf31a7282e16 ]
The following race condition still existed:
P1 P2
cancel_work_sync()
hci_uart_tx_wakeup()
hci_uart_write_work()
hci_uart_dequeue()
clear_bit(HCI_UART_PROTO_READY)
hci_unregister_dev(hdev)
hci_free_dev(hdev)
hu->proto->close(hu)
kfree(hu)
access to hdev and hu
Cancelling the work after clearing the HCI_UART_PROTO_READY bit avoids
this as any hci_uart_tx_wakeup() issued after the flag is cleared will
detect that and not schedule further work.

When the hw queue is busy, we shouldn't take requests from the scheduler
queue any more, otherwise it is difficult to do IO merge.
This patch fixes the awful IO performance on some SCSI devices(lpfc,
qla2xxx, ...) when mq-deadline/kyber is used by not taking requests if
hw queue is busy.

[ Upstream commit c157313791a999646901b3e3c6888514ebc36d62 ]
Currently, Cache missed IOs are identified by s->cache_miss, but actually,
there are many situations that missed IOs are not assigned a value for
s->cache_miss in cached_dev_cache_miss(), for example, a bypassed IO
(s->iop.bypass = 1), or the cache_bio allocate failed. In these situations,
it will go to out_put or out_submit, and s->cache_miss is null, which leads
bch_mark_cache_accounting() to treat this IO as a hit IO.

From: Liang Chen <liangchen.linux(a)gmail.com>
[ Upstream commit 330a4db89d39a6b43f36da16824eaa7a7509d34d ]
mutex_destroy does nothing most of time, but it's better to call
it to make the code future proof and it also has some meaning
for like mutex debug.
As Coly pointed out in a previous review, bcache_exit() may not be
able to handle all the references properly if userspace registers
cache and backing devices right before bch_debug_init runs and
bch_debug_init failes later. So not exposing userspace interface
until everything is ready to avoid that issue.

PATCH 1/2 is to fix switch upstream/downstream port error report.
PATCH 2/2 is to make AER device configuration more reasonable.
Delete the upstream/downstream port AER configuraion in PATCH 2/2,
but if firmware does not enable upstream/downstream port error reporting,
it seems current no place to enable them, so PATCH 2/2 need more
suggestion. Please see the commit log for more information.
Changes from v1:
- Rebase on v4.15-rc2.
- Modify the change log.
- Add PATCH 2/2.

MD's rdev_set_badblocks() expects that badblocks_set() returns 1 if
badblocks are disabled, otherwise, rdev_set_badblocks() will record
superblock changes and return success in that case and md will fail to
report an IO error which it should.

When the user sets count to zero the string buffer would remain
completely uninitialized which causes the kernel to parse its
own stack data, potentially leading to an info leak. In addition
to that, the string might be not terminated properly when the

Subject: ath10k: fix core PCI suspend when WoWLAN is supported but disabled
From: Brian Norris <briannorris(a)chromium.org>
[ Upstream commit 96378bd2c6cda5f04d0f6da2cd35d4670a982c38 ]
For devices where the FW supports WoWLAN but user-space has not
configured it, we don't do any PCI-specific suspend/resume operations,
because mac80211 doesn't call drv_suspend() when !wowlan. This has
particularly bad effects for some platforms, because we don't stop the
power-save timer, and if this timer goes off after the PCI controller
has suspended the link, Bad Things will happen.
Commit 32faa3f0ee50 ("ath10k: add the PCI PM core suspend/resume ops")
got some of this right, in that it understood there was a problem on
non-WoWLAN firmware. But it forgot the $subject case.
Fix this by moving all the PCI driver suspend/resume logic exclusively
into the driver PM hooks. This shouldn't affect WoWLAN support much
(this just gets executed later on).
I would just as well kill the entirety of ath10k_hif_suspend(), as it's
not even implemented on the USB or SDIO drivers. I expect that we don't
need the callback, except to return "supported" (i.e., 0) or "not
supported" (i.e., -EOPNOTSUPP).

[ Upstream commit 20665a9076d48e9abd9a2db13d307f58f7ef6647 ]
Build errors have been reported with CONFIG_PM=n:
drivers/net/wireless/ath/ath10k/pci.c:3416:8: error: implicit
declaration of function 'ath10k_pci_suspend'
[-Werror=implicit-function-declaration]
drivers/net/wireless/ath/ath10k/pci.c:3428:8: error: implicit
declaration of function 'ath10k_pci_resume'
[-Werror=implicit-function-declaration]
These are caused by the combination of the following two commits:
6af1de2e4ec4 ("ath10k: mark PM functions as __maybe_unused")
96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but
disabled")
Both build fine on their own.
But now that ath10k_pci_pm_{suspend,resume}() is compiled
unconditionally, we should also compile ath10k_pci_{suspend,resume}()
unconditionally.
And drop the #ifdef around ath10k_pci_hif_{suspend,resume}() too; they
are trivial (empty), so we're not saving much space by compiling them
out. And the alternatives would be to sprinkle more __maybe_unused, or
spread the #ifdef's further.
Build tested with the following combinations:
CONFIG_PM=y && CONFIG_PM_SLEEP=y
CONFIG_PM=y && CONFIG_PM_SLEEP=n
CONFIG_PM=n
Fixes: 96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but disabled")
Fixes: 096ad2a15fd8 ("Merge branch 'ath-next'")

Subject: arm64: prevent regressions in compressed kernel image size when upgrading to binutils 2.27
From: Nick Desaulniers <ndesaulniers(a)google.com>
[ Upstream commit fd9dde6abcb9bfe6c6bee48834e157999f113971 ]
Upon upgrading to binutils 2.27, we found that our lz4 and gzip
compressed kernel images were significantly larger, resulting is 10ms
boot time regressions.
As noted by Rahul:
"aarch64 binaries uses RELA relocations, where each relocation entry
includes an addend value. This is similar to x86_64. On x86_64, the
addend values are also stored at the relocation offset for relative
relocations. This is an optimization: in the case where code does not
need to be relocated, the loader can simply skip processing relative
relocations. In binutils-2.25, both bfd and gold linkers did this for
x86_64, but only the gold linker did this for aarch64. The kernel build
here is using the bfd linker, which stored zeroes at the relocation
offsets for relative relocations. Since a set of zeroes compresses
better than a set of non-zero addend values, this behavior was resulting
in much better lz4 compression.
The bfd linker in binutils-2.27 is now storing the actual addend values
at the relocation offsets. The behavior is now consistent with what it
does for x86_64 and what gold linker does for both architectures. The
change happened in this upstream commit:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=1f56df9d0d5ad8980…
Since a bunch of zeroes got replaced by non-zero addend values, we see
the side effect of lz4 compressed image being a bit bigger.
To get the old behavior from the bfd linker, "--no-apply-dynamic-relocs"
flag can be used:
$ LDFLAGS="--no-apply-dynamic-relocs" make
With this flag, the compressed image size is back to what it was with
binutils-2.25.
If the kernel is using ASLR, there aren't additional runtime costs to
--no-apply-dynamic-relocs, as the relocations will need to be applied
again anyway after the kernel is relocated to a random address.
If the kernel is not using ASLR, then presumably the current default
behavior of the linker is better. Since the static linker performed the
dynamic relocs, and the kernel is not moved to a different address at
load time, it can skip applying the relocations all over again."
Some measurements:
$ ld -v
GNU ld (binutils-2.25-f3d35cf6) 2.25.51.20141117
^
$ ls -l vmlinux
-rwxr-x--- 1 ndesaulniers eng 300652760 Oct 26 11:57 vmlinux

$ ls -l Image.lz4-dtb
-rw-r----- 1 ndesaulniers eng 16932466 Oct 26 12:06 Image.lz4-dtb
By Siqi's measurement w/ gzip:
binutils 2.27 with this patch (with --no-apply-dynamic-relocs):
Image 41535488
Image.gz 13404067
binutils 2.27 without this patch (without --no-apply-dynamic-relocs):
Image 41535488
Image.gz 14125516
Any compression scheme should be able to get better results from the
longer runs of zeros, not just GZIP and LZ4.
10ms boot time savings isn't anything to get excited about, but users of
arm64+compression+bfd-2.27 should not have to pay a penalty for no
runtime improvement.

Subject: usb: add helper to extract bits 12:11 of wMaxPacketSize
From: Felipe Balbi <felipe.balbi(a)linux.intel.com>
commit 541b6fe63023f3059cf85d47ff2767a3e42a8e44 upstream.
According to USB Specification 2.0 table 9-4,
wMaxPacketSize is a bitfield. Endpoint's maxpacket
is laid out in bits 10:0. For high-speed,
high-bandwidth isochronous endpoints, bits 12:11
contain a multiplier to tell us how many
transactions we want to try per uframe.
This means that if we want an isochronous endpoint
to issue 3 transfers of 1024 bytes per uframe,
wMaxPacketSize should contain the value:
1024 | (2 << 11)
or 5120 (0x1400). In order to make Host and
Peripheral controller drivers' life easier, we're
adding a helper which returns bits 12:11. Note that
no care is made WRT to checking endpoint type and
gadget's speed. That's left for drivers to handle.

Greg,
Upstream commit ("da2e6b7eeda8 ovl: fix overlay: warning prefix")
was not marked for stable, because it is not a bug fix per-se.
Nevertheless, it may be useful to apply it to stable kernels to keep
overlayfs bug reports/analysis consistent.
The first hunk fixes (#v4.10):
a6c606551141 ovl: redirect on rename-dir
The second hunk fixes (#v4.14):
b5efccbe0a12 ovl: constant d_ino across copy up
For your consideration.
If you wish, I can send a patch for v4.10 with just the first hunk.
Thanks,
Amir.
Hi,
Can following commit be included in stable kernel releases starting from
v4.11?
d9018976cdb6eefc62a7ba79a405f6c9661b08a7 ("mfd: lpc_ich: Do not touch SPI-NOR write protection bit on Haswell/Broadwell")
This makes sure older kernels will not accidentally lose the BIOS
settings.
Thanks!

commit 57629915d568c522ac1422df7bba4bee5b5c7a7c upstream.
The code was setting the capabilities byte to zero,
after it was already properly set previously. Fix it.
The bug was found while debugging hwsim mesh tests failures
that happened since the commit mentioned below.

Subject: KEYS: add missing permission check for request_key() destination
From: Eric Biggers <ebiggers(a)google.com>
commit 4dca6ea1d9432052afb06baf2e3ae78188a4410b upstream.
When the request_key() syscall is not passed a destination keyring, it
links the requested key (if constructed) into the "default" request-key
keyring. This should require Write permission to the keyring. However,
there is actually no permission check.
This can be abused to add keys to any keyring to which only Search
permission is granted. This is because Search permission allows joining
the keyring. keyctl_set_reqkey_keyring(KEY_REQKEY_DEFL_SESSION_KEYRING)
then will set the default request-key keyring to the session keyring.
Then, request_key() can be used to add keys to the keyring.
Both negatively and positively instantiated keys can be added using this
method. Adding negative keys is trivial. Adding a positive key is a
bit trickier. It requires that either /sbin/request-key positively
instantiates the key, or that another thread adds the key to the process
keyring at just the right time, such that request_key() misses it
initially but then finds it in construct_alloc_key().
Fix this bug by checking for Write permission to the keyring in
construct_get_dest_keyring() when the default keyring is being used.
We don't do the permission check for non-default keyrings because that
was already done by the earlier call to lookup_user_key(). Also,
request_key_and_link() is currently passed a 'struct key *' rather than
a key_ref_t, so the "possessed" bit is unavailable.
We also don't do the permission check for the "requestor keyring", to
continue to support the use case described by commit 8bbf4976b59f
("KEYS: Alter use of key instantiation link-to-keyring argument") where
/sbin/request-key recursively calls request_key() to add keys to the
original requestor's destination keyring. (I don't know of any users
who actually do that, though...)

commit 911b79cde95c7da0ec02f48105358a36636b7a71 upstream.
If request_key() is used to find a keyring, only do the search part - don't
do the construction part if the keyring was not found by the search. We
don't really want keyrings in the negative instantiated state since the
rejected/negative instantiation error value in the payload is unioned with
keyring metadata.
Now the kernel gives an error:

Subject: Don't leak a key reference if request_key() tries to use a revoked keyring
From: David Jeffery <djeffery(a)redhat.com>
commit d0709f1e66e8066c4ac6a54620ec116aa41937c0 upstream.
If a request_key() call to allocate and fill out a key attempts to insert the
key structure into a revoked keyring, the key will leak, using memory and part
of the user's key quota until the system reboots. This is from a failure of
construct_alloc_key() to decrement the key's reference count after the attempt
to insert into the requested keyring is rejected.
key_put() needs to be called in the link_prealloc_failed callpath to ensure
the unused key is released.
