Pull rdma fixes from Doug Ledford:
"No beating around the bush: this is a monster pull request for an -rc5
kernel. Intel hit me with a series of fixes for TID processing.
Mellanox hit me with a series for their UMR memory support.
And we had one fix for siw that fixes the 32bit build warnings and
because of the number of casts that had to be changed to properly
silence the warnings, that one patch alone is a full 40% of the LOC of
this entire pull request. Given that this is the initial release
kernel for siw, I'm trying to fix anything in it that we can, so that
adds to the impetus to take fixes for it like this one.
I had to do a rebase early in the week. Jason had thought he put a
patch on the rc queue that he needed to be there so he could base some
work off of it, and it had actually not been placed there. So he asked
me (on Tuesday) to fix that up before pushing my wip branch to the
official rc branch. I did, and that's why the early patches look like
they were all committed at the same time on Tuesday. That bunch had
been in my queue prior.
The various patches all pass my test for being legitimate fixes and
not attempts to slide new features or development into a late rc.
Well, they were all fixes with the exception of a couple clean up
patches people wrote for making the fixes they also wrote better (like
a cleanup patch to move UMR checking into a function so that the
remaining UMR fix patches can reference that function), so I left
those in place too.
My apologies for the LOC count and the number of patches here, it's
just how the cards fell this cycle.
Summary:
- Fix siw buffer mapping issue
- Fix siw 32/64 casting issues
- Fix a KASAN access issue in bnxt_re

At the moment we initialise the target *mask* of a virtual IRQ to the
VCPU it belongs to, even though this mask is only defined for GICv2 and
quickly runs out of bits for many GICv3 guests.
This behaviour triggers an UBSAN complaint for more than 32 VCPUs:
------
[ 5659.462377] UBSAN: Undefined behaviour in virt/kvm/arm/vgic/vgic-init.c:223:21
[ 5659.471689] shift exponent 32 is too large for 32-bit type 'unsigned int'
------
Also for GICv3 guests the reporting of TARGET in the "vgic-state" debugfs
dump is wrong, due to this very same problem.
Because there is no requirement to create the VGIC device before the
VCPUs (and QEMU actually does it the other way round), we can't safely
initialise mpidr or targets in kvm_vgic_vcpu_init(). But since we touch
every private IRQ for each VCPU anyway later (in vgic_init()), we can
just move the initialisation of those fields into there, where we
definitely know the VGIC type.
On the way make sure we really have either a VGICv2 or a VGICv3 device,
since the existing code is just checking for "VGICv3 or not", silently
ignoring the uninitialised case.

If the sector number is too high, dm_table_find_target() should return a
pointer to a zeroed dm_target structure (the caller should test it with
dm_target_is_valid).
However, for some table sizes, the code in dm_table_find_target() that
performs btree lookup will access out of bound memory structures.
Fix this bug by testing the sector number at the beginning of
dm_table_find_target(). Also, add an "inline" keyword to the function
dm_table_get_size() because this is a hot path.

Benjamin Moody reported to Debian that XFS partially wedges when a chgrp
fails on account of being out of disk quota. I ran his reproducer
script:
# adduser dummy
# adduser dummy plugdev
# dd if=/dev/zero bs=1M count=100 of=test.img
# mkfs.xfs test.img
# mount -t xfs -o gquota test.img /mnt
# mkdir -p /mnt/dummy
# chown -c dummy /mnt/dummy
# xfs_quota -xc 'limit -g bsoft=100k bhard=100k plugdev' /mnt
(and then as user dummy)
$ dd if=/dev/urandom bs=1M count=50 of=/mnt/dummy/foo
$ chgrp plugdev /mnt/dummy/foo
and saw:
================================================
WARNING: lock held when returning to user space!
5.3.0-rc5 #rc5 Tainted: G W
------------------------------------------------
chgrp/47006 is leaving the kernel with locks still held!

#0: 000000006664ea2d (&xfs_nondir_ilock_class){++++}, at: xfs_ilock+0xd2/0x290 [xfs]

Fixes i2c on DP with some docks.

While I had thought I had fixed this issue in:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
It turns out that while I did fix the error messages I was seeing on my
P50 when trying to access i2c busses with the GPU in runtime suspend, I
accidentally had missed one important detail that was mentioned on the
bug report this commit was supposed to fix: that the CPU would only lock
up when trying to access i2c busses _on connected devices_ _while the
GPU is not in runtime suspend_. Whoops. That definitely explains why I
was not able to get my machine to hang with i2c bus interactions until
now, as plugging my P50 into it's dock with an HDMI monitor connected
allowed me to finally reproduce this locally.
Now that I have managed to reproduce this issue properly, it looks like
the problem is much simpler then it looks. It turns out that some
connected devices, such as MST laptop docks, will actually ACK i2c reads
even if no data was actually read:
[ 275.063043] nouveau 0000:01:00.0: i2c: aux 000a: 1: 0000004c 1
[ 275.063447] nouveau 0000:01:00.0: i2c: aux 000a: 00 01101000 10040000
[ 275.063759] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000001
[ 275.064024] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[ 275.064285] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[ 275.064594] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
Because we don't handle the situation of i2c ack without any data, we
end up entering an infinite loop in nvkm_i2c_aux_i2c_xfer() since the
value of cnt always remains at 0. This finally properly explains how
this could result in a CPU hang like the ones observed in the
aforementioned commit.
So, fix this by retrying transactions if no data is written or received,
and give up and fail the transaction if we continue to not write or
receive any data after 32 retries.

The outer poll loop checks for whether we need to reschedule, and
returns to userspace if we do. However, it's possible to get stuck
in the inner loop as well, if the CPU we are running on needs to
reschedule to finish the IO work.
Add the need_resched() check in the inner loop as well. This fixes
a potential hang if the kernel is configured with
CONFIG_PREEMPT_VOLUNTARY=y.

When btree_split_beneath() splits a node to two new children, it will
allocate two blocks: left and right. If right block's allocation
failed, the left block will be unlocked and marked dirty. If this
happened, the left block'ss content is zero, because it wasn't
initialized with the btree struct before the attempot to allocate the
right block. Upon return, when flushing the left block to disk, the
validator will fail when check this block. Then a BUG_ON is raised.
Fix this by completely initializing the left block before allocating and
initializing the right block.

All user level and most in-kernel applications submit WQEs
where the SG list entries are all of a single type.
iSER in particular, however, will send us WQEs with mixed SG
types: sge[0] = kernel buffer, sge[1] = PBL region.
Check and set is_kva on each SG entry individually instead of
assuming the first SGE type carries through to the last.
This fixes iSER over siw.

Driver copies FW commands to the HW queue as units of 16 bytes. Some
of the command structures are not exact multiple of 16. So while copying
the data from those structures, the stack out of bounds messages are

If the inode from afs_do_lookup() is an error other than ENOENT, or if it
is ENOENT and afs_try_auto_mntpt() returns an error, the trace event will
try to dereference the error pointer as a valid pointer.
Use IS_ERR_OR_NULL to only pass a valid pointer for the trace, or NULL.

the oops.

Fix a leak on the cell refcount in afs_lookup_cell_rcu() due to
non-clearance of the default error in the case a NULL cell name is passed
and the workstation default cell is used.
Also put a bit at the end to make sure we don't leak a cell ref if we're
going to be returning an error.
This leak results in an assertion like the following when the kafs module is
unloaded:

0x2 == 0x1 is false

If after an MMIO exit to userspace a VCPU is immediately run with an
immediate_exit request, such as when a signal is delivered or an MMIO
emulation completion is needed, then the VCPU completes the MMIO
emulation and immediately returns to userspace. As the exit_reason
does not get changed from KVM_EXIT_MMIO in these cases we have to
be careful not to complete the MMIO emulation again, when the VCPU is
eventually run again, because the emulation does an instruction skip
(and doing too many skips would be a waste of guest code :-) We need
to use additional VCPU state to track if the emulation is complete.
As luck would have it, we already have 'mmio_needed', which even
appears to be used in this way by other architectures already.

We can't rely on ->peer_features in calc_target() because it may be
called both when the OSD session is established and open and when it's
not. ->peer_features is not valid unless the OSD session is open. If
this happens on a PG split (pg_num increase), that could mean we don't
resend a request that should have been resent, hanging the client
indefinitely.
In userspace this was fixed by looking at require_osd_release and
get_xinfo[osd].features fields of the osdmap. However these fields
belong to the OSD section of the osdmap, which the kernel doesn't
decode (only the client section is decoded).
Instead, let's drop this feature check. It effectively checks for
luminous, so only pre-luminous OSDs would be affected in that on a PG
split the kernel might resend a request that should not have been
resent. Duplicates can occur in other scenarios, so both sides should
already be prepared for them: see dup/replay logic on the OSD side and
retry_attempt check on the client side.

[Why]
The only place where state->max_bpc is updated on the connector is
at the start of atomic check during drm_atomic_connector_check. It
isn't updated when adding the connectors to the atomic state after
the fact. It also doesn't necessarily reflect the right value when
called in amdgpu during mode validation outside of atomic check.
This can cause the wrong bpc to be used even if the max_requested_bpc
is the correct value.
[How]
Don't rely on state->max_bpc reflecting the real bpc value and just
do the min(...) based on display info bpc and max_requested_bpc.
Fixes: 01933ba42d3d ("drm/amd/display: Use current connector state if NULL when checking bpc")

Error out if the AMDGPU_CS ioctl is called with multiple SYNCOBJ_OUT and/or
TIMELINE_SIGNAL chunks, since otherwise the last chunk wins while the
allocated array as well as the reference counts of sync objects are leaked.
