installing them, since they're not needed anyway on the architecture.

A previous commit tried to make the ratelimiter timings test more
reliable but in the process made it less reliable on other
configurations. This is an impossible problem to solve without
increasingly ridiculous heuristics. And it's not even a problem that
actually needs to be solved in any comprehensive way, since this is only
ever used during development. So just cordon this off with a DEBUG_
ifdef, just like we do for the trie's randomized tests, so it can be
enabled while hacking on the code, and otherwise disabled in CI. In the
process we also revert 151c8e499f47.

Pull vfs fix from Christian Brauner:
"Beginning of the merge window we introduced the vfs{g,u}id_t types in
b27c82e12965 ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
When userspace passes -1 for an ownership change the ownership fields
in struct iattr stay uninitialized. Usually this is fine because any
code making use of any fields in struct iattr must check the
->ia_valid field whether the value of interest has been initialized.
That's true for all struct iattr passing code.
However, over the course of the last year with more heavy use of KMSAN
we found quite a few places that got this wrong. A recent one I fixed
was 3cb6ee991496 ("9p: only copy valid iattrs in 9P2000.L setattr
implementation").
But we also have LSM hooks. Actually we have two. The first one is
security_inode_setattr() in notify_change() which does the right thing
and passes the full struct iattr down to LSMs and thus LSMs can check
whether it is initialized.
But then we also have security_path_chown() which passes down a path
argument and the target ownership as the filesystem would see it. For
the latter we now generate the target values based on struct iattr and
pass it down. However, when userspace passes -1 then struct iattr
isn't initialized.
This patch simply initializes ->ia_vfs{g,u}id with INVALID_VFS{G,U}ID
so the hook continue to see invalid ownership when -1 is passed from
userspace. The only LSM that cares about the actual values is Tomoyo.
The vfs codepaths don't look at these fields without ->ia_valid being
set so there's no harm in initializing ->ia_vfs{g,u}id. Arguably this
is also safer since we can't end up copying valid ownership values
when invalid ownership values should be passed.
This only affects mainline. No kernel has been released with this and
thus no backport is needed. The commit is thus marked with a Fixes:
tag but annotated with "# mainline only" (I didn't quite remember what
Greg said about how to tell stable autoselect to not bother with fixes
for mainline only)"

These functions expect to be called from RCU read-side critical section,
but this only happens when invoked from the data path via
ip{,6}_mr_input(). They can also be invoked from process context in
response to user space adding a multicast route which resolves a cache
entry with queued packets [1][2].
Fix by adding missing rcu_read_lock() / rcu_read_unlock() in these call
paths.

IPA can route packets between IPA-connected entities. The AP and
modem are currently the only such entities supported, and no routing
is required to transfer packets between them.
The number of entries in each routing table is fixed, and defined at
initialization time. Some of these entries are designated for use
by the modem, and the rest are available for the AP to use. The AP
sends a QMI message to the modem which describes (among other
things) information about routing table memory available for the
modem to use.
Currently the QMI initialization packet gives wrong information in
its description of routing tables. What *should* be supplied is the
maximum index that the modem can use for the routing table memory
located at a given location. The current code instead supplies the
total *number* of routing table entries. Furthermore, the modem is
granted the entire table, not just the subset it's supposed to use.
This patch fixes this. First, the ipa_mem_bounds structure is
generalized so its "end" field can be interpreted either as a final
byte offset, or a final array index. Second, the IPv4 and IPv6
(non-hashed and hashed) table information fields in the QMI
ipa_init_modem_driver_req structure are changed to be ipa_mem_bounds
rather than ipa_mem_array structures. Third, we set the "end" value
for each routing table to be the last index, rather than setting the
"count" to be the number of indices. Finally, instead of allowing
the modem to use all of a routing table's memory, it is limited to
just the portion meant to be used by the modem. In all versions of
IPA currently supported, that is IPA_ROUTE_MODEM_COUNT (8) entries.
Update a few comments for clarity.

i915_perf assumes that it can use the i915_gem_context reference to
protect its i915->gem.contexts.list iteration. However, this requires
that we do not remove the context from the list until after we drop the
final reference and release the struct. If, as currently, we remove the
context from the list during context_close(), the link.next pointer may
be poisoned while we are holding the context reference and cause a GPF:

Due to i915_perf assuming that it can use the i915_gem_context reference
to protect its i915->gem.contexts.list iteration, we need to defer removal
of the context from the list until last reference to the context is put.
However, there is a risk of triggering kernel warning on contexts list not
empty at driver release time if we deleagate that task to a worker for
i915_gem_context_release_work(), unless that work is flushed first.
Unfortunately, it is not flushed on driver release. Fix it.
Instead of additionally calling flush_workqueue(), either directly or via
a new dedicated wrapper around it, replace last call to
i915_gem_drain_freed_objects() with existing i915_gem_drain_workqueue()
that performs both tasks.

This reverts commit a09b314005f3a0956ebf56e01b3b80339df577cc.
Dusty Mabe reported consistent hang during CoreOS shutdown with a MD
RAID1 setup. Although apparently similar hangs happened before,
and this patch most likely is not the root cause it made it much
more severe. Revert it until we can figure out what is going on
with the md driver.

We now remove the device's debugfs entries when unbinding the driver.

Before we switched to ->read_skb(), ->read_sock() was passed with
desc.count=1, which technically indicates we only read one skb per
->sk_data_ready() call. However, for TCP, this is not true.
TCP at least has sk_rcvlowat which intentionally holds skb's in
receive queue until this watermark is reached. This means when
->sk_data_ready() is invoked there could be multiple skb's in the
queue, therefore we have to read multiple skbs in tcp_read_skb()
instead of one.

Maximum frame length check is enabled in lan937x switch on POR, But it
is found to be disabled on driver during port setup operation. Due to
this, packets are not dropped when transmitted with greater than configured
value. For testing, setup made for lan1->lan2 transmission and configured
lan1 interface with a frame length (less than 1500 as mentioned in
documentation) and transmitted packets with greater than configured value.
Expected no packets at lan2 end, but packets observed at lan2.
Based on the documentation, packets should get discarded if the actual
packet length doesn't match the frame length configured. Frame length check
should be disabled only for cascaded ports due to tailtags.
This feature was disabled on ksz9477 series due to ptp issue, which is
not in lan937x series. But since lan937x took ksz9477 as base, frame
length check disabled here as well. Patch added to remove this portion
from port setup so that maximum frame length check will be active for
normal ports.

Beginning of the merge window we introduced the vfs{g,u}id_t types in
b27c82e12965 ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
During that change we forgot to account for the case were the passed
ownership value is -1. In this case the ownership fields in struct iattr
aren't initialized but we rely on them being initialized by the time we
generate the ownership to pass down to the LSMs. All the major LSMs
don't care about the ownership values at all. Only Tomoyo uses them and
so it took a while for syzbot to unearth this issue.
Fix this by initializing the ownership fields and do it within the
retry_deleg block. While notify_change() doesn't alter the ownership
fields currently we shouldn't rely on it.
Since no kernel has been released with these changes this does not
needed to be backported to any stable kernels.

The Kconfig symbol depended on MMU but was dropped by the commit
acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu")
because it already had as a dependency ARM64 that already selects MMU.
But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built

when COMPILE_TEST is set but that could lead to unmet direct dependencies

G200ER does not seem to support 24 bpp, so force the console to
use 32 bpp. The problem got introduced when commit 73f54d5d9682
("drm/mgag200: Remove special case for G200SE with <2 MiB") changed
the preferred color depth from 32 bit to 24 bit.
A setting of 24 is the correct color depth, but G200ER doesn't seem
to be able to use the respective RGB888 color format. Using 24-bit
color with forced 32 bpp works around the problem.

Trying to get the channel from the tx_queue variable here is wrong
because we can only be here if tx_queue is NULL, so we shouldn't
dereference it. As the above comment in the code says, this is very
unlikely to happen, but it's wrong anyway so let's fix it.
I hit this issue because of a different bug that caused tx_queue to be
NULL. If that happens, this is the error message that we get here:

In legacy interrupt mode the tx_channel_offset was hardcoded to 1, but
that's not correct if efx_sepparate_tx_channels is false. In that case,
the offset is 0 because the tx queues are in the single existing channel
at index 0, together with the rx queue.
Without this fix, as soon as you try to send any traffic, it tries to
get the tx queues from an uninitialized channel getting these errors:

While converting max_tx_rate from bytes to Mbps, this value was set to 0,
if the original value was lower than 125000 bytes (1 Mbps). This would
cause no transmission rate limiting to occur. This happened due to lack of
check of max_tx_rate against the 1 Mbps value for max_tx_rate and the
following division by 125000. Fix this issue by adding a helper
i40e_bw_bytes_to_mbits() which sets max_tx_rate to minimum usable value of
50 Mbps, if its value is less than 1 Mbps, otherwise do the required
conversion by dividing by 125000.

After setting port VLAN and MTU to 9000 on VF with ice driver there
was an iavf error
"PF returned error -5 (IAVF_ERR_PARAM) to our request 6".
During queue configuration, VF's max packet size was set to
IAVF_MAX_RXBUFFER but on ice max frame size was smaller by VLAN_HLEN
due to making some space for port VLAN as VF is not aware whether it's
in a port VLAN. This mismatch in sizes caused ice to reject queue
configuration with ERR_PARAM error. Proper max_mtu is sent from ice PF
to VF with GET_VF_RESOURCES msg but VF does not look at this.
In iavf change max_frame from IAVF_MAX_RXBUFFER to max_mtu
received from pf with GET_VF_RESOURCES msg to make vf's
max_frame_size dependent from pf. Add check if received max_mtu is
not in eligible range then set it to IAVF_MAX_RXBUFFER.

OpenWrt's UML with 5.15 was producing odd errors/warnings during preinit
part of the early userspace portion:
|[ 0.000000] Kernel command line: ubd0=root.img root=98:0 console=tty
|[...]
|[ 0.440000] random: jshn: uninitialized urandom read (4 bytes read)
|[ 0.460000] random: jshn: uninitialized urandom read (4 bytes read)
|/etc/preinit: line 47: can't create /dev/tty: No such device or address
|/etc/preinit: line 48: can't create /dev/tty: No such device or address
|/etc/preinit: line 58: can't open /dev/tty: No such device or address
|[...] repeated many times
That "/dev/tty" came from the command line (which is automatically
added if no console= parameter was specified for the uml binary).
The TLDP project tells the following about the /dev/tty:
<https://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3>
| /dev/tty stands for the controlling terminal (if any) for the current
| process.[...]
| /dev/tty is something like a link to the actually terminal device[..]
The "(if any)" is important here, since it's possible for processes to
not have a controlling terminal.
I think this was a simple typo and the author wanted tty0 there.

arch.tls_array is statically allocated so checking for NULL doesn't
make sense. This causes the compiler warning below.
Remove the checks to silence these warnings.

With commit 0c24e061196c ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.
Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.
