...
tcp_fragment() might be called for skbs in the write queue.
Memory limits might have been exceeded because tcp_sendmsg() only
checks limits at full skb (64KB) boundaries.
Therefore, we need to make sure tcp_fragment() wont punish applications
that might have setup very low SO_SNDBUF values.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Doug Ledford:
"This is probably our last -rc pull request. We don't have anything
else outstanding at the moment anyway, and with the summer months on
us and people taking trips, I expect the next weeks leading up to the
merge window to be pretty calm and sedate.
This has two simple, no brainer fixes for the EFA driver.
Then it has ten not quite so simple fixes for the hfi1 driver. The
problem with them is that they aren't simply one liner typo fixes.
They're still fixes, but they're more complex issues like livelock
under heavy load where the answer was to change work queue usage and
spinlock usage to resolve the problem, or issues with orphaned
requests during certain types of failures like link down which
required some more complex work to fix too. They all look like
legitimate fixes to me, they just aren't small like I wish they were.
Summary:
- 2 minor EFA fixes
- 10 hfi1 fixes related to scaling issues"

NFS4: Only set creation opendata if O_CREAT
GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock
pages before the vclock mode checks. This creates a path through
vclock_gettime() in which no vclock is enabled at all (due to disabled
TSC on old CPUs, for example) but the pvclock or hvclock page
nevertheless read. This will segfault on bare metal.
This fixes commit 459e3a2153 ("gcc-9: properly declare the
{pv,hv}clock_page storage") in the sense that, before that commit, GCC
didn't seem to generate the offending code. There was nothing wrong
with that commit per se, and -stable maintainers should backport this to
all supported kernels regardless of whether the offending commit was
present, since the same crash could just as easily be triggered by the
phase of the moon.
On GCC 9.1.1, this doesn't seem to affect the generated code at all, so
I'm not too concerned about performance regressions from this fix.

which occurs because using a kernel side submission thread isn't valid
without using fixed files (registered through io_uring_register()). This
causes io_uring to put the request after logging an error, but before
the file field is set in the request. If it happens to be non-zero, we
attempt to fput() garbage.
Fix this by ensuring that req->file is initialized when the request is
allocated.

"I have been noticing intermittent failures with a system suspend test on
some of our machines that have a NFS mounted root file-system. Bisecting
this issue points to your commit 431235818b ("SUNRPC: Declare RPC
timers as TIMER_DEFERRABLE") and reverting this on top of v5.2-rc3 does
appear to resolve the problem.
The cause of the suspend failure appears to be a long delay observed
sometimes when resuming from suspend, and this is causing our test to
timeout."

We can end up in nfs4_opendata_alloc during task exit, in which case
current->fs has already been cleaned up. This leads to a crash in
current_umask().
Fix this by only setting creation opendata if we are actually doing an open
with O_CREAT. We can drop the check for NULL nfs4_open_createattrs, since
O_CREAT will never be set for the recovery path.

They include 2 xhci bugfixes, a chipidea fix, and a small dwc2 fix.
Nothing major, just nice things to get resolved for reported issues.
All have been in linux-next with no reported issues.

Another round of SPDX updates for 5.2-rc6
Here is what I am guessing is going to be the last "big" SPDX update for
5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that
were "easy" to determine by pattern matching. The ones after this are
going to be a bit more difficult and the people on the spdx list will be
discussing them on a case-by-case basis now.
Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529
Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576
This is a huge improvement.
Also, we deleted another 20000 lines of boilerplate license crud, always
nice to see in a diffstat.

The commit fe00e50b2d ("ARM: 8858/1: vdso: use $(LD) instead of $(CC)
to link VDSO") removed the passing of CFLAGS, since ld doesn't take
those directly. However, prior, big-endian ARM was relying on gcc to
translate its -mbe8 option into ld's --be8 option. Lacking this, ld
generated be32 code, making the VDSO generate SIGILL when called by
userspace.
This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled.

Once we unlock adapter->hw_lock in pvscsi_queue_lck() nothing prevents just
queued scsi_cmnd from completing and freeing the request. Thus cmd->cmnd[0]
dereference can dereference already freed request leading to kernel crashes
or other issues (which one of our customers observed). Store cmd->cmnd[0]
in a local variable before unlocking adapter->hw_lock to fix the issue.

Merge tag 'kvmarm-fixes-for-5.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm fixes for 5.2, take #2
- SVE cleanup killing a warning with ancient GCC versions
- Don't report non-existent system registers to userspace
- Fix memory leak when freeing the vgic ITS
- Properly lower the interrupt on the emulated physical timer
Commit 332d079735 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS
state before setting new state", 2019-05-02) broke evmcs_test because the
eVMCS setup must be performed even if there is no VMXON region defined,
as long as the eVMCS bit is set in the assist page.
While the simplest possible fix would be to add a check on
kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that
covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.
Instead, this patch moves checks earlier in the function and
conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that
vmx_set_nested_state always goes through vmx_leave_nested
and nested_enable_evmcs.

Because I made the afs_call struct share pointers to an afs_server object
and an afs_vlserver object to save space, afs_put_call() calls
afs_put_server() on afs_vlserver object (which is only meant for the
afs_server object) because it sees that call->server isn't NULL.
This means that the afs_vlserver object gets unpredictably and randomly
modified, depending on what config options are set (such as lockdep).
Fix this by getting rid of the union and having two non-overlapping
pointers in the afs_call struct.

Occasionally, warnings like this:
vnode modified 2af7 on {10000b:1} [exp 2af2] YFS.FetchStatus(vnode)
are emitted into the kernel log. This indicates that when we were applying
the updated vnode (file) status retrieved from the server to an inode we
saw that the data version number wasn't what we were expecting (in this
case it's 0x2af7 rather than 0x2af2).
We've usually received a callback from the server prior to this point - or
the callback promise has lapsed - so the warning is merely informative and
the state is to be expected.
Fix this by only emitting the warning if the we still think that we have a
valid callback promise and haven't received a callback.
Also change the format slightly so so that the new data version doesn't
look like part of the text, the like is prefixed with "kAFS: " and the
message is ranked as a warning.

While the DOC at the beginning of lib/bitmap.c explicitly states that
"The number of valid bits in a given bitmap does _not_ need to be an
exact multiple of BITS_PER_LONG.", some of the bitmap operations do
indeed access BITS_PER_LONG portions of the provided bitmap no matter
the size of the provided bitmap.
For example, if find_first_bit() is provided with an 8 bit bitmap the
operation will access BITS_PER_LONG bits from the provided bitmap. While
the operation ensures that these extra bits do not affect the result,
the memory is still accessed.
The capacity bitmasks (CBMs) are typically stored in u32 since they
can never exceed 32 bits. A few instances exist where a bitmap_*
operation is performed on a CBM by simply pointing the bitmap operation
to the stored u32 value.
The consequence of this pattern is that some bitmap_* operations will
access out-of-bounds memory when interacting with the provided CBM.
This same issue has previously been addressed with commit 49e00eee00
("x86/intel_rdt: Fix out-of-bounds memory access in CBM tests")
but at that time not all instances of the issue were fixed.
Fix this by using an unsigned long to store the capacity bitmask data
that is passed to bitmap functions.

Convert vm_insert_pages() to use vm_map_pages_zero(). We could later

When a guest vcpu moves from one physical thread to another it is
necessary for the host to perform a tlb flush on the previous core if
another vcpu from the same guest is going to run there. This is because the
guest may use the local form of the tlb invalidation instruction meaning
stale tlb entries would persist where it previously ran. This is handled
on guest entry in kvmppc_check_need_tlb_flush() which calls
flush_guest_tlb() to perform the tlb flush.
Previously the generic radix__local_flush_tlb_lpid_guest() function was
used, however the functionality was reimplemented in flush_guest_tlb()
to avoid the trace_tlbie() call as the flushing may be done in real
mode. The reimplementation in flush_guest_tlb() was missing an erat
invalidation after flushing the tlb.
This lead to observable memory corruption in the guest due to the
caching of stale translations. Fix this by adding the erat invalidation.

calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment
purposes. It included "../../../../include/linux/sizes.h" to define
that size, however "sizes.h" tries to include <linux/const.h> which
assumes linux system headers. These may not exist eg. the following
error was encountered when building Linux for OpenWrt under macOS:

Presently, there is no path to DMA map P2PDMA memory, so if a TLP targeting
this memory hits the root complex and an IOMMU is present, the IOMMU will
reject the transaction, even if the RC would support P2PDMA.
So until the kernel knows to map these DMA addresses in the IOMMU, we
should not enable the whitelist when an IOMMU is present.
