While most libraries do not need a CONFIG_* symbol because the
"when:" clauses are enough, some do. Add them back or stop
using them if possible.
In the case of libpmem, the statement to add the CONFIG_* symbol
was still in configure, but could not be triggered because it
checked for "no" instead of "disabled" (and it would be wrong anyway
since the test for the library has not been done yet).

The PL061 comes out of reset with all its lines configured as input,
which means they might need to be pulled to 0 or 1 depending on the

these lines on reset; they will only be set whenever the guest first
touches a register that triggers a call to pl061_update().

can safely call qemu_set_irq() to set the floating lines to their

For the virt board we have two PL061 devices -- one for NonSecure which

we don't care whether its outputs are pulled low or high when the line is
configured as an input, because we don't connect them. For the latter,
we do care, because we wire the lines up to the gpio-pwr device, which
assumes that level 1 means "do the action" and 1 means "do nothing".

PL061s to pull GPIO lines down to 0.

The PL061 GPIO does not itself include pullup or pulldown resistors
to set the value of a GPIO line treated as an output when it is
configured as an input (ie when the PL061 itself is not driving it).
In real hardware it is up to the board to add suitable pullups or
pulldowns. Currently our implementation hardwires this to "outputs
pulled high", which is correct for some boards (eg the realview ones:
see figure 3-29 in the "RealView Platform Baseboard for ARM926EJ-S
User Guide" DUI0224I), but wrong for others.
In particular, the wiring in the 'virt' board and the gpio-pwr device
assumes that wires should be pulled low, because otherwise the
pull-to-high will trigger a shutdown or reset action. (The only
reason this doesn't happen immediately on startup is due to another
bug in the PL061, where we don't assert the GPIOs to the correct
value on reset, but will do so as soon as the guest touches a
register and pl061_update() gets called.)
Add properties to the pl061 so the board can configure whether it
wants GPIO lines to have pullup, pulldown, or neither.

The Luminary variant of the PL061 has registers GPIOPUR and GPIOPDR
which lets the guest configure whether the GPIO lines are pull-up,
pull-down, or truly floating. Instead of assuming all lines are pulled
high, honour the PUR and PDR registers.
For the plain PL061, continue to assume that lines have an external
pull-up resistor, as we did before.
The stellaris board actually relies on this behaviour -- the CD line
of the ssd0323 display device is connected to GPIO output C7, and it
is only because of a different bug which we're about to fix that we
weren't incorrectly driving this line high on reset and putting the
ssd0323 into data mode.

icv_eoir_write() and icv_dir_write() ignore invalid virtual IRQ numbers
(like LPIs). The issue is that these functions check against the number
of implemented IRQs (QEMU's default is num_irq=288) which can be lower
than the maximum virtual IRQ number (1020 - 1). The consequence is that
if a hypervisor creates an LR for an IRQ between 288 and 1020, then the
guest is unable to deactivate the resulting IRQ. Note that other
functions that deal with large IRQ numbers, like icv_iar_read, check
against 1020 and not against num_irq.
Fix the checks by using GICV3_MAXIRQ (1020) instead of the number of
implemented IRQs.

Without the allow_other mount option, no user (not even root) but the
one who started qemu/the storage daemon can access the export. Allow
users to configure the export such that such accesses are possible.
While allow_other is probably what users want, we cannot make it an
unconditional default, because passing it is only possible (for non-root
users) if the global fuse.conf configuration file allows it. Thus, the
default is an 'auto' mode, in which we first try with allow_other, and
then fall back to without.
FuseExport.allow_other reports whether allow_other was actually used as
a mount option or not. Currently, this information is not used, but a
future patch will let this field decide whether e.g. an export's UID and
GID can be changed through chmod.
One notable thing about 'auto' mode is that libfuse may print error
messages directly to stderr, and so may fusermount (which it executes).
Our export code cannot really filter or hide them. Therefore, if 'auto'
fails its first attempt and has to fall back, fusermount will print an
error message that mounting with allow_other failed.
This behavior necessitates a change to iotest 308, namely we need to
filter out this error message (because if the first attempt at mounting
with allow_other succeeds, there will be no such message).
Furthermore, common.rc's _make_test_img should use allow-other=off for
FUSE exports, because iotests generally do not need to access images
from other users, so allow-other=on or allow-other=auto have no
advantage. OTOH, allow-other=on will not work on systems where
user_allow_other is disabled, and with allow-other=auto, we get said
error message that we would need to filter out again. Just disabling
allow-other is simplest.

This patch wittingly sets BDRV_REQ_NO_FALLBACK and silently ignores
BDRV_REQ_MAY_UNMAP for older librbd versions.
The rationale for this is as follows (citing Ilya Dryomov current RBD
maintainer):
---8<---
a) remove the BDRV_REQ_MAY_UNMAP check in qemu_rbd_co_pwrite_zeroes()
and as a consequence always unmap if librbd is too old
It's not clear what qemu's expectation is but in general Write
Zeroes is allowed to unmap. The only guarantee is that subsequent
reads return zeroes, everything else is a hint. This is how it is
specified in the kernel and in the NVMe spec.
In particular, block/nvme.c implements it as follows:
if (flags & BDRV_REQ_MAY_UNMAP) {
cdw12 |= (1 << 25);
}
This sets the Deallocate bit. But if it's not set, the device may
still deallocate:
"""
If the Deallocate bit (CDW12.DEAC) is set to '1' in a Write Zeroes
command, and the namespace supports clearing all bytes to 0h in the
values read (e.g., bits 2:0 in the DLFEAT field are set to 001b)
from a deallocated logical block and its metadata (excluding
protection information), then for each specified logical block, the
controller:
- should deallocate that logical block;
...
If the Deallocate bit is cleared to '0' in a Write Zeroes command,
and the namespace supports clearing all bytes to 0h in the values
read (e.g., bits 2:0 in the DLFEAT field are set to 001b) from
a deallocated logical block and its metadata (excluding protection
information), then, for each specified logical block, the
controller:
- may deallocate that logical block;
"""
https://nvmexpress.org/wp-content/uploads/NVM-Express-NVM-Command-Set-Specification-2021.06.02-Ratified-1.pdf
b) set BDRV_REQ_NO_FALLBACK in supported_zero_flags
Again, it's not clear what qemu expects here, but without it we end
up in a ridiculous situation where specifying the "don't allow slow
fallback" switch immediately fails all efficient zeroing requests on
a device where Write Zeroes is always efficient:
$ qemu-io -c 'help write' | grep -- '-[zun]'
-n, -- with -z, don't allow slow fallback
-u, -- with -z, allow unmapping
-z, -- write zeroes using blk_co_pwrite_zeroes
$ qemu-io -f rbd -c 'write -z -u -n 0 1M' rbd:foo/bar
write failed: Operation not supported

Ceph Luminous (version 12.2.z) is almost 4 years old at this point.
Bump the requirement to get rid of the ifdef'ry in the code.
Qemu 6.1 dropped the support for RHEL-7 which was the last supported
OS that required an older librbd.

Starting from ceph Pacific, RBD has built-in support for image-level encryption.
Currently supported formats are LUKS version 1 and 2.
There are 2 new relevant librbd APIs for controlling encryption, both expect an
open image context:
rbd_encryption_format: formats an image (i.e. writes the LUKS header)
rbd_encryption_load: loads encryptor/decryptor to the image IO stack
This commit extends the qemu rbd driver API to support the above.

Jason has moved on from working on RBD and Ceph. I'm taking over
his role upstream.
