- binutils v2.36 has changed the handling of the assembler's
  -mx86-used-note, resulting in a build failure. To compensate, we

Subject: block: Separate blk_is_writable() and blk_supports_write_perm()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 86b1cf322789b79c8ace977430ac6a443d491cc0
Currently, blk_is_read_only() tells whether a given BlockBackend can
only be used in read-only mode because its root node is read-only. Some
callers actually try to answer a slightly different question: Is the
BlockBackend configured to be writable, by taking write permissions on
the root node?
This can differ, for example, for CD-ROM devices which don't take write
permissions, but may be backed by a writable image file. scsi-cd allows
write requests to the drive if blk_is_read_only() returns false.
However, the write request will immediately run into an assertion
failure because the write permission is missing.
This patch introduces separate functions for both questions.
blk_supports_write_perm() answers the question whether the block
node/image file can support writable devices, whereas blk_is_writable()
tells whether the BlockBackend is currently configured to be writable.
All calls of blk_is_read_only() are converted to one of the two new
functions.

Subject: build: be explicit about -mx86-used-note=no
binutils v2.36 switched the default for the assembler's -mx86-used-note,
which caused breakage building seavgabios as follows:
ld: section .note.gnu.property LMA [0000000000000000,0000000000000027]

Subject: hw/intc/arm_gic: Fix interrupt ID in GICD_SGIR register
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: edfe2eb4360cde4ed5d95bda7777edcb3510f76a
Per the ARM Generic Interrupt Controller Architecture specification
(document "ARM IHI 0048B.b (ID072613)"), the SGIINTID field is 4 bit,
not 10:
- 4.3 Distributor register descriptions
- 4.3.15 Software Generated Interrupt Register, GICD_SG
- Table 4-21 GICD_SGIR bit assignments
The Interrupt ID of the SGI to forward to the specified CPU
interfaces. The value of this field is the Interrupt ID, in
the range 0-15, for example a value of 0b0011 specifies
Interrupt ID 3.
Correct the irq mask to fix an undefined behavior (which eventually
lead to a heap-buffer-overflow, see [Buglink]):
$ echo 'writel 0x8000f00 0xff4affb0' | qemu-system-aarch64 -M virt,accel=qtest -qtest stdio

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../hw/intc/arm_gic.c:1498:13
This fixes a security issue when running with KVM on Arm with
kernel-irqchip=off. (The default is kernel-irqchip=on, which is
unaffected, and which is also the correct choice for performance.)

Subject: hw/timer/slavio_timer: Allow 64-bit accesses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 62a9b228b5fefe0f9e364dfeaf3c65022c63cdb9
Per the "NCR89C105 Chip Specification" referenced in the header:
Chip-level Address Map
------------------------------------------------------------------
| 1D0 0000 -> | Counter/Timers | W,D |
| 1DF FFFF | | |
...
The address map indicated the allowed accesses at each address.
[...] W indicates a word access, and D indicates a double-word
access.
The SLAVIO timer controller is implemented expecting 32-bit accesses.
Commit a3d12d073e1 restricted the memory accesses to 32-bit, while
the device allows 64-bit accesses.
This was not an issue until commit 5d971f9e67 which reverted
("memory: accept mismatching sizes in memory_region_access_valid").
Fix by renaming .valid MemoryRegionOps as .impl, and add the valid
access range (W -> 4, D -> 8).
Since commit 21786c7e598 ("memory: Log invalid memory accesses")
this class of bug can be quickly debugged displaying 'guest_errors'
accesses, as:
$ qemu-system-sparc -M SS-20 -m 256 -bios ss20_v2.25_rom -serial stdio -d guest_errors
Power-ON Reset
Invalid access at addr 0x0, size 8, region 'timer-1', reason: invalid size (min:4 max:4)

Subject: net: Fix handling of id in netdev_add and netdev_del
Git-commit: 831734cce6494032e9233caff4d8442b3a1e7fef
CLI -netdev accumulates in option group "netdev".
Before commit 08712fcb85 "net: Track netdevs in NetClientState rather
than QemuOpt", netdev_add added to the option group, and netdev_del
removed from it, both HMP and QMP. Thus, every netdev had a
corresponding QemuOpts in this option group.
Commit 08712fcb85 dropped this for QMP netdev_add and both netdev_del.
Now a netdev has a corresponding QemuOpts only when it was created
with CLI or HMP. Two issues:
* QMP and HMP netdev_del can leave QemuOpts behind, breaking HMP
netdev_add. Reproducer:
$ qemu-system-x86_64 -S -display none -nodefaults -monitor stdio
QEMU 5.1.92 monitor - type 'help' for more information
(qemu) netdev_add user,id=net0
(qemu) info network
net0: index=0,type=user,net=10.0.2.0,restrict=off
(qemu) netdev_del net0
(qemu) info network
(qemu) netdev_add user,id=net0
upstream-qemu: Duplicate ID 'net0' for netdev
Try "help netdev_add" for more information
Fix by restoring the QemuOpts deletion in qmp_netdev_del(), but with
a guard, because the QemuOpts need not exist.
* QMP netdev_add loses its "no duplicate ID" check. Reproducer:
$ qemu-system-x86_64 -S -display none -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 92, "minor": 1, "major": 5}, "package": "v5.2.0-rc2-1-g02c1f0142c"}, "capabilities": ["oob"]}}
{"execute": "qmp_capabilities"}
{"return": {}}
{"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}}
{"return": {}}
{"execute": "netdev_add", "arguments": {"type": "user", "id":"net0"}}
{"return": {}}
Fix by adding a duplicate ID check to net_client_init1() to replace
the lost one. The check is redundant for callers where QemuOpts
still checks, i.e. for CLI and HMP.

- binutils v2.36 has changed the handling of the assembler's
-mx86-used-note, resulting in a build failure. To compensate, we
now explicitly specify -mx86-used-note=no in the seabios Makefile
(boo#1181775)

Subject: target/arm: Don't decode insns in the XScale/iWMMXt space as cp insns
Git-commit: e4d51ac6921dc861bfb3d20e4c7dcf345840a9da
In commit cd8be50e58f63413c0 we converted the A32 coprocessor
insns to decodetree. This accidentally broke XScale/iWMMXt insns,
because it moved the handling of "cp insns which are handled
by looking up the cp register in the hashtable" from after the
call to the legacy disas_xscale_insn() decode to before it,
with the result that all XScale/iWMMXt insns now UNDEF.
Update valid_cp() so that it knows that on XScale cp 0 and 1
are not standard coprocessor instructions; this will cause
the decodetree trans_ functions to ignore them, so that
execution will correctly get through to the legacy decode again.

Git-commit: cc97b0019bb590b9b3c2a623e9ebee48831e0ce3
In 50244cc76abc we updated mte_check_fail to match the ARM
pseudocode, using the correct EL to select the TCF field.
But we failed to update MTE0_ACTIVE the same way, which led
to g_assert_not_reached().

Subject: target/arm: Introduce PREDDESC field definitions
Git-commit: b64ee454a4a086ed459bcda4c0bbb54e197841e4
SVE predicate operations cannot use the "usual" simd_desc
encoding, because the lengths are not a multiple of 8.
But we were abusing the SIMD_* fields to store values anyway.
This abuse broke when SIMD_OPRSZ_BITS was modified in e2e7168a214.
Introduce a new set of field definitions for exclusive use
of predicates, so that it is obvious what kind of predicate
we are manipulating. To be used in future patches.

Git-commit: 86300b5d044064046395ae8ed605cc19e63f2a7c
These two were odd, in that do_pfirst_pnext passed the
count of 64-bit words rather than bytes. Change to pass
the standard pred_full_reg_size to avoid confusion.

Subject: tcg: Use memset for large vector byte replication
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 6d3ef04893bdea3e7aa08be3cce5141902836a31
In f47db80cc07, we handled odd-sized tail clearing for
the case of hosts that have vector operations, but did
not handle the case of hosts that do not have vector ops.
This was ok until e2e7168a214b, which changed the encoding
of simd_desc such that the odd sizes are impossible.
Add memset as a tcg helper, and use that for all out-of-line
byte stores to vectors. This includes, but is not limited to,
the tail clearing operation in question.

Subject: virtio: move 'use-disabled-flag' property to hw_compat_4_2
Git-commit: c126b4c57e0164549de606ca35d1512762051083
Commit 9d7bd0826f introduced a new 'use-disabled-flag' property
set to true by default.
To allow the migration, we set this property to false in the hw_compat,
but in the wrong place (hw_compat_4_1).
Since commit 9d7bd0826f was released with QEMU 5.0, we move
'use-disabled-flag' property to hw_compat_4_2, so 4.2 machine types
will have the pre-patch behavior and the migration can work.
The issue was discovered with vhost-vsock device and 4.2 machine
type without running any kernel in the VM:
$ qemu-4.2 -M pc-q35-4.2,accel=kvm \
-device vhost-vsock-pci,guest-cid=4 \
-monitor stdio -incoming tcp:0:3333
$ qemu-5.2 -M pc-q35-4.2,accel=kvm \
-device vhost-vsock-pci,guest-cid=3 \
-monitor stdio
(qemu) migrate -d tcp:0:3333
# qemu-4.2 output
qemu-system-x86_64: Failed to load virtio-vhost_vsock:virtio
qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:03.0/virtio-vhost_vsock'
