Check that block node activation and inactivation works with a block
graph that is built with individually created nodes.
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
Reviewed-by: Max Reitz <mreitz@redhat.com>
The previous patch fixed the inherits_from pointer after block-stream,
and this one does the same for block-commit.
When block-commit finishes and the 'top' node is not the topmost one
from the backing chain then all nodes above 'base' up to and including
'top' are removed from the chain.
The bdrv_drop_intermediate() call converts a chain like this one:
base <- intermediate <- top <- active
into this one:
base <- active
In a simple scenario each backing file from the first chain has the
inherits_from attribute pointing to its parent. This means that
reopening 'active' will recursively reopen all its children, whose
options can be changed in the process.
However after the 'block-commit' call base.inherits_from is NULL and
the chain is broken, so 'base' does not inherit from 'active' and will
not be reopened automatically:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
$ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
$ $QEMU -drive if=none,file=hd2.qcow2
{ 'execute': 'block-commit',
'arguments': {
'device': 'none0',
'top': 'hd1.qcow2' } }
{ 'execute': 'human-monitor-command',
'arguments': {
'command-line':
'qemu-io none0 "reopen -o backing.l2-cache-size=2M"' } }
{ "return": "Cannot change the option 'backing.l2-cache-size'\r\n"}
This patch updates base.inherits_from in this scenario, and adds a
test case.

Signed-off-by: Kevin Wolf <kwolf@redhat.com>
When a BlockDriverState's child is opened (be it a backing file, the
protocol layer, or any other) inherits_from is set to point to the
parent node. Children opened separately and then attached to a parent
don't have this pointer set.
bdrv_reopen_queue_child() uses this to determine whether a node's
children must also be reopened inheriting the options from the parent
or not. If inherits_from points to the parent then the child is
reopened and its options can be changed, like in this example:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 hd1.qcow2 1M
$ $QEMU -drive if=none,node-name=hd0,file=hd0.qcow2,\
backing.driver=qcow2,backing.file.filename=hd1.qcow2
(qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"
If the child does not inherit from the parent then it does not get
reopened and its options cannot be changed:
$ $QEMU -drive if=none,node-name=hd1,file=hd1.qcow2
-drive if=none,node-name=hd0,file=hd0.qcow2,backing=hd1
(qemu) qemu-io hd0 "reopen -o backing.l2-cache-size=2M"
Cannot change the option 'backing.l2-cache-size'
If a disk image has a chain of backing files then all of them are also
connected through their inherits_from pointers (i.e. it's possible to
walk the chain in reverse order from base to top).
However this is broken if the intermediate nodes are removed using
e.g. block-stream because the inherits_from pointer from the base node
becomes NULL:
$ qemu-img create -f qcow2 hd0.qcow2 1M
$ qemu-img create -f qcow2 -b hd0.qcow2 hd1.qcow2
$ qemu-img create -f qcow2 -b hd1.qcow2 hd2.qcow2
$ $QEMU -drive if=none,file=hd2.qcow2
(qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
(qemu) block_stream none0 0 hd0.qcow2
(qemu) qemu-io none0 "reopen -o backing.l2-cache-size=2M"
Cannot change the option 'backing.l2-cache-size'
This patch updates the inherits_from pointer if the intermediate nodes
of a backing chain are removed using bdrv_set_backing_hd(), and adds a
test case for this scenario.

Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
error. This is CVE-2018-16847.
Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient. However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works. Add a basic testcase for the CMB in case
somebody does this change later on.

If you have a capable file system (tmpfs is good, ext4 not so much;
run ./check with TEST_DIR pointing to a good location so as not
to skip the test), it's actually possible to create a qcow2 file
that expands to a sparse 512T image with just over 38M of content.
The test is not the world's fastest (qemu crawling through 256M
bits of refcount table to find the next cluster to allocate takes
several seconds, as does qemu-img check reporting millions of
leaked clusters); but it DOES catch the problem that the previous
patch just fixed where writing a compressed cluster to a full
image ended up overwriting the wrong cluster.

TEST linux-test on i386
.../tests/tcg/multiarch/linux-test.c:201: readdir
readdir() calls getdents64() to have the list of the entries in a
directory, and getdents64() can return 64bit d_off values (with ext4,
for instance) that will not fit in the 32bit d_off field of the
readdir() dirent structure.
To avoid that, use readdir64() to use a 64bit d_off field too.

In commit 9fa99d2519 ("hw/pci-host: Fix x86 Host Bridges 64bit PCI
hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in
the ACPI DSDT that would be at least as large as the new "pci-hole64-size"
property (2GB on i440fx, 32GB on q35). The goal was to offer "enough"
64-bit MMIO aperture to the guest OS for hotplug purposes.
Previous patch fixed the issue that the aperture is extended relative to
a possibly incorrect base. This may result in an aperture size that is
smaller than the intent of commit 9fa99d2519.
This patch adds a test to make sure it won't happen again.
In the test case being added:
- use 128 MB initial RAM size,
- ask for one DIMM hotplug slot,
- ask for 2 GB maximum RAM size,
- use a pci-testdev with a 64-bit BAR of 2 GB size.
Consequences:
(1) In pc_memory_init() [hw/i386/pc.c], the DIMM hotplug area size is
initially set to 2048-128 = 1920 MB. (Maximum RAM size minus initial
RAM size.)
(2) The DIMM area base is set to 4096 MB (because the initial RAM is only
128 MB -- there is no initial "high RAM").
(3) Due to commit 085f8e88ba ("pc: count in 1Gb hugepage alignment when
sizing hotplug-memory container", 2014-11-24), we add 1 GB for the one
DIMM hotplug slot that was specified. This sets the DIMM area size to
1920+1024 = 2944 MB.
(4) The reserved-memory-end address (exclusive) is set to 4096 + 2944 =
7040 MB (DIMM area base plus DIMM area size).
(5) The reserved-memory-end address is rounded up to GB alignment,
yielding 7 GB (7168 MB).
(6) Given the 2 GB BAR size of pci-testdev, SeaBIOS allocates said 64-bit
BAR in 64-bit address space.
(7) Because reserved-memory-end is at 7 GB, it is unaligned for the 2 GB
BAR. Therefore SeaBIOS allocates the BAR at 8 GB. QEMU then
(correctly) assigns the root bridge aperture base this BAR address, to
be exposed in \_SB.PCI0._CRS.
(8) The intent of commit 9fa99d2519 dictates that QEMU extend the
aperture size to 32 GB, implying a 40 GB end address. However, QEMU
performs the extension relative to reserved-memory-end (7 GB), not
relative to the bridge aperture base that was correctly deduced from
SeaBIOS's BAR programming (8 GB). Therefore we see 39 GB as the
aperture end address in \_SB.PCI0._CRS:

Currently tests/hex-loader-check-data contains data files used
by the hexloader-test, and configure individually symlinks those
data files into the build directory using a wildcard.
Using a wildcard like this is a bad idea, because if a new
data file is added, nothing causes configure to be rerun,
and so no symlink is added for the new file. This can cause
tests to spuriously fail when they can't find their data.
Instead, it's better to symlink an entire directory of
data files. We already have such a directory: tests/data.
Move the data files from tests/hex-loader-check-data/ to
tests/data/hex-loader/, and remove the unnecessary symlinking.

We can remove entirely the note in rebuild-expected-aml.sh
about copying any new data files, because now they will
be in the source directory, not the build directory, and
no copying is required.
(We can't just change the existing tests/acpi-test-data/
to being a symlinked directory, because if we did that and
a developer switched git branches from one after that change
to one before it then configure would end up trashing all
the test files by making them symlinks to themselves.
Changing their path avoids this annoyance.)

This adds some whitespace into the option help (including indentation)
and puts angle brackets around the type names. Furthermore, the list
name is no longer printed as part of every line, but only once in
advance, and only if the caller did not print a caption already.
This patch also restores the description alignment we had before commit
9cbef9d68e, just at 24 instead of 16 characters like we used to.
This increase is because now we have the type and two spaces of
indentation before the description, and with a usual type name length of
three chracters, this sums up to eight additional characters -- which
means that we now need 24 characters to get the same amount of padding
for most options. Also, 24 is a third of 80, which makes it kind of a
round number in terminal terms.
Finally, this patch amends the reference output of iotest 082 to match
the changes (and thus makes it pass again).
