This tag contains fixes, defconfig, and DT data changes for the v5.2-rc
series. The fixes are relatively straightforward:
- Addition of a TLB fence in the vmalloc_fault path, so the CPU doesn't
enter an infinite page fault loop;
- Readdition of the pm_power_off export, so device drivers that
reassign it can now be built as modules;
- A udelay() fix for RV32, fixing a miscomputation of the delay time;
- Removal of deprecated smp_mb__*() barriers.
The tag also adds initial DT data infrastructure for arch/riscv, along
with initial data for the SiFive FU540-C000 SoC and the corresponding
HiFive Unleashed board.
We also update the RV64 defconfig to include some core drivers for the
FU540 in the build.

When multiple iovecs reference the same page, each get_user_page call
will add a reference to the page. But once we've created the bio that
information gets lost and only a single reference will be dropped after
I/O completion. Use the same_page information returned from
__bio_try_merge_page to drop additional references to pages that were
already present in the bio.
Based on a patch from Ming Lei.

We currently have an input same_page parameter to __bio_try_merge_page
to prohibit merging in the same page. The rationale for that is that
some callers need to account for every page added to a bio. Instead of
letting these callers call twice into the merge code to account for the
new vs existing page cases, just turn the paramter into an output one that
returns if a merge in the same page occured and let them act accordingly.

After the recent series of cleanups in the properties and xattrs modules
that landed in the 5.2 merge window, we ended up with a regression where
after deleting the compression xattr property through the setflags ioctl,
we don't set the BTRFS_INODE_COPY_EVERYTHING flag in the inode anymore.
As a consequence, if the inode was fsync'ed when it had the compression
property set, after deleting the compression property through the setflags
ioctl and fsync'ing again the inode, the log will still contain the
compression xattr, because the inode did not had that bit set, which
made the fsync not delete all xattrs from the log and copy all xattrs
from the subvolume tree to the log tree.
This regression happens due to the fact that that series of cleanups
made btrfs_set_prop() call the old function do_setxattr() (which is now
named btrfs_setxattr()), and not the old version of btrfs_setxattr(),
which is now called btrfs_setxattr_trans().
Fix this by setting the BTRFS_INODE_COPY_EVERYTHING bit in the current
btrfs_setxattr() function and remove it from everywhere else, including
its setup at btrfs_ioctl_setflags(). This is cleaner, avoids similar
regressions in the future, and centralizes the setup of the bit. After
all, the need to setup this bit should only be in the xattrs module,
since it is an implementation of xattrs.

An endpoint conflict occurs when the USB is working in device mode
during an isochronous communication. When the endpointA IN direction
is an isochronous IN endpoint, and the host sends an IN token to
endpointA on another device, then the OUT transaction may be missed
regardless the OUT endpoint number. Generally, this occurs when the
device is connected to the host through a hub and other devices are
connected to the same hub.
The affected OUT endpoint can be either control, bulk, isochronous, or
an interrupt endpoint. After the OUT endpoint is primed, if an IN token
to the same endpoint number on another device is received, then the OUT
endpoint may be unprimed (cannot be detected by software), which causes
this endpoint to no longer respond to the host OUT token, and thus, no
corresponding interrupt occurs.
There is no good workaround for this issue, the only thing the software
could do is numbering isochronous IN from the highest endpoint since we
have observed most of device number endpoint from the lowest.

documentation to json-schema YAML format. Start by converting our cpu
binding documentation. While doing so, document more properties and

and U54 CPU cores ("harts") that are present on this SoC. These cores
are described in:
https://static.dev.sifive.com/FU540-C000-v1.0.pdf

lapb_register calls lapb_create_cb, which initializes the control-
block's ref-count to one, and __lapb_insert_cb, which increments it when
adding the new block to the list of blocks.
lapb_unregister calls __lapb_remove_cb, which decrements the ref-count
when removing control-block from the list of blocks, and calls lapb_put
itself to decrement the ref-count before returning.
However, lapb_unregister also calls __lapb_devtostruct to look up the
right control-block for the given net_device, and __lapb_devtostruct
also bumps the ref-count, which means that when lapb_unregister returns
the ref-count is still 1 and the control-block is leaked.
Call lapb_put after __lapb_devtostruct to fix leak.

Number of Rx queues used for flow hashing returned by the driver is
incorrect and this bug prevents user to use the last Rx queue in
indirection table.
Let's say we have a NIC with 6 combined queues:
[root@sm-03 ~]# ethtool -l enp4s0f0
Channel parameters for enp4s0f0:
Pre-set maximums:
RX: 5
TX: 5
Other: 0
Combined: 6
Current hardware settings:
RX: 0
TX: 0
Other: 0
Combined: 6
Default indirection table maps all (6) queues equally but the driver
reports only 5 rings available.
[root@sm-03 ~]# ethtool -x enp4s0f0
RX flow hash indirection table for enp4s0f0 with 5 RX ring(s):
0: 0 1 2 3 4 5 0 1
8: 2 3 4 5 0 1 2 3
16: 4 5 0 1 2 3 4 5
24: 0 1 2 3 4 5 0 1
...
Now change indirection table somehow:
[root@sm-03 ~]# ethtool -X enp4s0f0 weight 1 1
[root@sm-03 ~]# ethtool -x enp4s0f0
RX flow hash indirection table for enp4s0f0 with 6 RX ring(s):
0: 0 0 0 0 0 0 0 0
...
64: 1 1 1 1 1 1 1 1
...
Now it is not possible to change mapping back to equal (default) state:

"The accumulated fixes from this and last week:
- Fix vmalloc TLB flush and map range calculations which lead to
stale TLBs, spurious faults and other hard to diagnose issues.
- Use fault_in_pages_writable() for prefaulting the user stack in the
FPU code as it's less fragile than the current solution
- Use the PF_KTHREAD flag when checking for a kernel thread instead
of current->mm as the latter can give the wrong answer due to
use_mm()
- Compute the vmemmap size correctly for KASLR and 5-Level paging.
Otherwise this can end up with a way too small vmemmap area.
- Make KASAN and 5-level paging work again by making sure that all
invalid bits are masked out when computing the P4D offset. This
worked before but got broken recently when the LDT remap area was
moved.
- Prevent a NULL pointer dereference in the resource control code
which can be triggered with certain mount options when the
requested resource is not available.
- Enforce ordering of microcode loading vs. perf initialization on
secondary CPUs. Otherwise perf tries to access a non-existing MSR
as the boot CPU marked it as available.
- Don't stop the resource control group walk early otherwise the
control bitmaps are not updated correctly and become inconsistent.
- Unbreak kgdb by returning 0 on success from
kgdb_arch_set_breakpoint() instead of an error code.
- Add more Icelake CPU model defines so depending changes can be
queued in other trees"

Some TCP peers announce a very small MSS option in their SYN and/or
SYN/ACK messages.
This forces the stack to send packets with a very high network/cpu
overhead.
Linux has enforced a minimal value of 48. Since this value includes
the size of TCP options, and that the options can consume up to 40
bytes, this means that each segment can include only 8 bytes of payload.
In some cases, it can be useful to increase the minimal value
to a saner value.
We still let the default to 48 (TCP_MIN_SND_MSS), for compatibility
reasons.
Note that TCP_MAXSEG socket option enforces a minimal value
of (TCP_MIN_MSS). David Miller increased this minimal value
in commit c39508d6f1 ("tcp: Make TCP_MAXSEG minimum more correct.")
from 64 to 88.
We might in the future merge TCP_MIN_SND_MSS and TCP_MIN_MSS.

Jonathan Looney reported that a malicious peer can force a sender
to fragment its retransmit queue into tiny skbs, inflating memory
usage and/or overflow 32bit counters.
TCP allows an application to queue up to sk_sndbuf bytes,
so we need to give some allowance for non malicious splitting
of retransmit queue.
A new SNMP counter is added to monitor how many times TCP
did not allow to split an skb if the allowance was exceeded.
Note that this counter might increase in the case applications
use SO_SNDBUF socket option to lower sk_sndbuf.

Jonathan Looney reported that TCP can trigger the following crash
in tcp_shifted_skb() :
BUG_ON(tcp_skb_pcount(skb) < pcount);
This can happen if the remote peer has advertized the smallest
MSS that linux TCP accepts : 48
An skb can hold 17 fragments, and each fragment can hold 32KB
on x86, or 64KB on PowerPC.
This means that the 16bit witdh of TCP_SKB_CB(skb)->tcp_gso_segs
can overflow.
Note that tcp_sendmsg() builds skbs with less than 64KB
of payload, so this problem needs SACK to be enabled.
SACK blocks allow TCP to coalesce multiple skbs in the retransmit
queue, thus filling the 17 fragments to maximal capacity.
CVE-2019-11477 -- u16 overflow of TCP_SKB_CB(skb)->tcp_gso_segs

This reverts commit ef7bfa8472.
Russell King espressed some strong opposition to this
change, explaining that this is trying to make phylink
behave outside of how it has been designed.

BPF_PROG_TYPE_RAW_TRACEPOINTs can be executed nested on the same CPU, as
they do not increment bpf_prog_active while executing.
This enables three levels of nesting, to support
- a kprobe or raw tp or perf event,
- another one of the above that irq context happens to call, and
- another one in nmi context
(at most one of which may be a kprobe or perf event).

bpf_sk_storage maps use multiple spin locks to reduce contention.
The number of locks to use is determined by the number of possible CPUs.
With only 1 possible CPU, bucket_log == 0, and 2^0 = 1 locks are used.
When updating elements, the correct lock is determined with hash_ptr().
Calling hash_ptr() with 0 bits is undefined behavior, as it does:
x >> (64 - bits)
Using the value results in an out of bounds memory access.
In my case, this manifested itself as a page fault when raw_spin_lock_bh()
is called later, when running the self tests:

Force the minimum number of locks to two.

Set the SOCK_DONE flag to match the TCP_CLOSING state when a peer has
shut down and there is nothing left to read.
This fixes the following bug:
1) Peer sends SHUTDOWN(RDWR).
2) Socket enters TCP_CLOSING but SOCK_DONE is not set.
3) read() returns -ENOTCONN until close() is called, then returns 0.

We get this regression when using RTL8366RB as part of a bridge
with OpenWrt:
WARNING: CPU: 0 PID: 1347 at net/switchdev/switchdev.c:291
switchdev_port_attr_set_now+0x80/0xa4
lan0: Commit of attribute (id=7) failed.
(...)
realtek-smi switch lan0: failed to initialize vlan filtering on this port
This is because it is trying to disable VLAN filtering
on VLAN0, as we have forgot to add 1 to the port number
to get the right VLAN in rtl8366_vlan_filtering(): when
we initialize the VLAN we associate VLAN1 with port 0,
VLAN2 with port 1 etc, so we need to add 1 to the port
offset.

The phy_state field of phylink should carry only valid information
especially when this can be passed to the .mac_config callback.
Update the an_enabled field with the autoneg state in the
phylink_phy_change function.
