Ming Lei and others added 27 commits January 9, 2022 18:54
Commit cc9c884 ("block: call submit_bio_checks under q_usage_counter")
uses q_usage_counter to protect submit_bio_checks for avoiding IO after
disk is deleted by del_gendisk().

Turns out the protection isn't necessary, because once
blk_mq_freeze_queue_wait() in del_gendisk() returns:

1) all in-flight IO has been done

2) all new IO will be failed in __bio_queue_enter() because
   q_usage_counter is dead, and GD_DEAD is set

3) both disk and request queue instance are safe since caller of
submit_bio() guarantees that the disk can't be closed.

Once submit_bio_checks() needn't the protection of q_usage_counter, we can
move submit_bio_checks before calling blk_mq_submit_bio() and
->submit_bio(). With this change, we needn't to throttle queue with
holding one allocated request, then precise driver tag or request won't be
wasted in throttling. Meantime we can unify the bio check for both bio
based and request based driver.

Sort the documentation for the files alphabetically by file path so that
there is a logical order and it's clear where to add new files.

With two small exceptions, this patch doesn't change the documentation
itself and just reorders it:

- In /sys/block/<disk>/<part>/stat, I replaced <part> with <partition>
  to be consistent with the other files.
- The description for /sys/block/<disk>/<part>/stat referred to another
  file "above", which I reworded.

sysfs documentation is supposed to go in Documentation/ABI/.
However, /sys/block/<disk>/queue/* are documented in
Documentation/block/queue-sysfs.rst, and sometimes redundantly in
Documentation/ABI/stable/sysfs-block too.

Let's consolidate this documentation into Documentation/ABI/.

Therefore, copy the relevant docs from queue-sysfs.rst into sysfs-block.

This primarily means adding the 25 missing files that were documented in
queue-sysfs.rst only, as well as mentioning the RO/RW status of files.

Documentation/ABI/ requires "Date" and "Contact" fields.  For the Date
fields, I used the date of the commit which added support for each file.
For the "Contact" fields, I used linux-block.

Commit 98c65a3 ("media: si2157: add support for 1.7MHz and 6.1
MHz") introduced two bugs: The 6.1MHz setting was always used for any
bandwidth less than 7MHz due to missing "else" keywords, and then the
setting was not specified as decimal 10, but as hexadecimal 0x10, which
makes the tuner refuse the tune command. In sum, it is not possible to
tune to any channels of less than 7MHz bandwidth anymore.

Add the missing "else" keywords and convert all bandwidth settings to
decimal to avoid any future decimal vs. hexadecimal confusion.

Remove the use of the undefined bandwidth setting 0x0f for bandwidths
greater than 8MHz, which is also refused by the tune command, in favour
of using the default bandwidth setting 8 for any bandwidths greater than
7MHz.

  to be allocated (at split time instead of insertion)"

Disallow memslots and MMIO SPTEs whose gpa range would exceed the host's
MAXPHYADDR, i.e. don't create SPTEs for gfns that exceed host.MAXPHYADDR.
The TDP MMU bounds its zapping based on host.MAXPHYADDR, and so if the
guest, possibly with help from userspace, manages to coerce KVM into
creating a SPTE for an "impossible" gfn, KVM will leak the associated
shadow pages (page tables):

On bare metal, encountering an impossible gpa in the page fault path is
well and truly impossible, barring CPU bugs, as the CPU will signal #PF
during the gva=>gpa translation (or a similar failure when stuffing a
physical address into e.g. the VMCS/VMCB).  But if KVM is running as a VM
itself, the MAXPHYADDR enumerated to KVM may not be the actual MAXPHYADDR
of the underlying hardware, in which case the hardware will not fault on
the illegal-from-KVM's-perspective gpa.

Alternatively, KVM could continue allowing the dodgy behavior and simply
zap the max possible range.  But, for hosts with MAXPHYADDR < 52, that's
a (minor) waste of cycles, and more importantly, KVM can't reasonably
support impossible memslots when running on bare metal (or with an
accurate MAXPHYADDR as a VM).  Note, limiting the overhead by checking if
KVM is running as a guest is not a safe option as the host isn't required
to announce itself to the guest in any way, e.g. doesn't need to set the
HYPERVISOR CPUID bit.

A second alternative to disallowing the memslot behavior would be to
disallow creating a VM with guest.MAXPHYADDR > host.MAXPHYADDR.  That
restriction is undesirable as there are legitimate use cases for doing
so, e.g. using the highest host.MAXPHYADDR out of a pool of heterogeneous
systems so that VMs can be migrated between hosts with different
MAXPHYADDRs without running afoul of the allow_smaller_maxphyaddr mess.

Note that any guest.MAXPHYADDR is valid with shadow paging, and it is
even useful in order to test KVM with MAXPHYADDR=52 (i.e. without
any reserved physical address bits).

The now common kvm_mmu_max_gfn() is inclusive instead of exclusive.
The memslot and TDP MMU code want an exclusive value, but the name
implies the returned value is inclusive, and the MMIO path needs an
inclusive check.
