-Subject: [PATCH] block/io_uring: revert "Use io_uring_register_ring_fd() to
- skip fd operations"
-
-Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1193
-
-The commit "Use io_uring_register_ring_fd() to skip fd operations" broke
-when booting a guest with iothread and io_uring. That is because the
-io_uring_register_ring_fd() call is made from the main thread instead of
-IOThread where io_uring_submit() is called. It can not be guaranteed
-to register the ring fd in the correct thread or unregister the same ring
-fd if the IOThread is disabled. This optimization is not critical so we
-will revert previous commit.
-
-This reverts commit e2848bc574fe2715c694bf8fe9a1ba7f78a1125a
-and 77e3f038af1764983087e3551a0fde9951952c4d.

-Subject: [PATCH] virtiofsd: use g_date_time_get_microsecond to get subsecond
-
-The "%f" specifier in g_date_time_format() is only available in glib
-2.65.2 or later. If combined with older glib, the function returns null
-and the timestamp displayed as "(null)".
-
-For backward compatibility, g_date_time_get_microsecond should be used
-to retrieve subsecond.
-
-In this patch the g_date_time_format() leaves subsecond field as "%06d"
-and let next snprintf to format with g_date_time_get_microsecond.

+
+When vIOMMU is enabled, the vq->used_phys is actually the IOVA not
+GPA. So we need to translate it to GPA before the syncing otherwise we
+may hit the following crash since IOVA could be out of the scope of
+the GPA log size. This could be noted when using virtio-IOMMU with

+Subject: [PATCH] memory: prevent dma-reentracy issues
+
+Add a flag to the DeviceState, when a device is engaged in PIO/MMIO/DMA.
+This flag is set/checked prior to calling a device's MemoryRegion
+handlers, and set when device code initiates DMA.  The purpose of this
+flag is to prevent two types of DMA-based reentrancy issues:
+
+1.) mmio -> dma -> mmio case
+2.) bh -> dma write -> mmio case
+
+These issues have led to problems such as stack-exhaustion and
+use-after-frees.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Host drivers do not necessarily set cdb_len in megasas io commands.
+With commits 6d1511cea0 ("scsi: Reject commands if the CDB length
+exceeds buf_len") and fe9d8927e2 ("scsi: Add buf_len parameter to
+scsi_req_new()"), this results in failures to boot Linux from affected
+SCSI drives because cdb_len is set to 0 by the host driver.
+Set the cdb length to its actual size to solve the problem.

+Subject: [PATCH] ide: avoid potential deadlock when draining during trim
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The deadlock can happen as follows:
+1. ide_issue_trim is called, and increments the in_flight counter.
+2. ide_issue_trim_cb calls blk_aio_pdiscard.
+3. Somebody else starts draining (e.g. backup to insert the cbw node).
+4. ide_issue_trim_cb is called as the completion callback for
+   blk_aio_pdiscard.
+5. ide_issue_trim_cb issues yet another blk_aio_pdiscard request.
+6. The request is added to the wait queue via blk_wait_while_drained,
+   because draining has been started.
+7. Nobody ever decrements the in_flight counter and draining can't
+   finish. This would be done by ide_trim_bh_cb, which is called after
+   ide_issue_trim_cb has issued its last request, but
+   ide_issue_trim_cb is not called anymore, because it's the
+   completion callback of blk_aio_pdiscard, which waits on draining.
+
+Quoting Hanna Czenczek:
+> The point of 7e5cdb345f was that we need any in-flight count to
+> accompany a set s->bus->dma->aiocb. While blk_aio_pdiscard() is
+> happening, we don’t necessarily need another count. But we do need
+> it while there is no blk_aio_pdiscard().
+> ide_issue_trim_cb() returns in two cases (and, recursively through
+> its callers, leaves s->bus->dma->aiocb set):
+> 1. After calling blk_aio_pdiscard(), which will keep an in-flight
+>    count,
+> 2. After calling replay_bh_schedule_event() (i.e.
+>    qemu_bh_schedule()), which does not keep an in-flight count.
+
+Thus, even after moving the blk_inc_in_flight to above the
+replay_bh_schedule_event call, the invariant "ide_issue_trim_cb
+returns with an accompanying in-flight count" is still satisfied.
+
+However, the issue 7e5cdb345f fixed for canceling resurfaces, because
+ide_cancel_dma_sync assumes that it just needs to drain once. But now
+the in_flight count is not consistently > 0 during the trim operation.
+So, change it to drain until !s->bus->dma->aiocb, which means that the
+operation finished (s->bus->dma->aiocb is cleared by ide_set_inactive
+via the ide_dma_cb when the end of the transfer is reached).
+

+In bad9c5a516 ("virtio-rng-pci: fix migration compat for vectors") I
+fixed the virtio-rng-pci migration compatibility, but it was discovered

+Subject: [PATCH] hw/timer/hpet: Fix expiration time overflow
+
+The expiration time provided for timer_mod() can overflow if a
+ridiculously large value is set to the comparator register. The
+resulting value can represent a past time after rounded, forcing the
+timer to fire immediately. If the timer is configured as periodic, it
+will rearm the timer again, and form an endless loop.
+
+Check if the expiration value will overflow, and if it will, stop the
+timer instead of rearming the timer with the overflowed time.
+
+This bug was found by Alexander Bulekov when fuzzing igb, a new
+network device emulation:
+https://patchew.org/QEMU/20230129053316.1071513-1-alxndr@bu.edu/
+
+The fixed test case is:
+fuzz/crash_2d7036941dcda1ad4380bb8a9174ed0c949bcefd

+Content-Transfer-Encoding: 8bit
+
+Not stopping them leave the device in a bad state when virtio-net
+fronted device is unplugged with device_del monitor command.
+
+This is not triggable in regular poweroff or qemu forces shutdown
+because cleanup is called right after vhost_vdpa_dev_start(false).  But
+devices hot unplug does not call vdpa device cleanups.  This lead to all
+the vhost_vdpa devices without stop the SVQ but the last.
+
+Fix it and clean the code, making it symmetric with
+vhost_vdpa_svqs_start.

+In char_socket_finalize after s->listener freed, event callback function
+vhost_user_blk_event will be called to handle CHR_EVENT_CLOSED.
+vhost_user_blk_event is calling qio_net_listener_set_client_func_full which
+is still using s->listener.
+
+Setting s->listener = NULL after object_unref(OBJECT(s->listener)) can
+solve this issue.

+ legacy reg block
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The modern ACPI CPU hotplug interface was introduced in the following
+series (aa1dd39ca307..679dd1a957df), released in v2.7.0:
+
+  1  abd49bc2ed2f docs: update ACPI CPU hotplug spec with new protocol
+  2  16bcab97eb9f pc: piix4/ich9: add 'cpu-hotplug-legacy' property
+  3  5e1b5d93887b acpi: cpuhp: add CPU devices AML with _STA method
+  4  ac35f13ba8f8 pc: acpi: introduce AcpiDeviceIfClass.madt_cpu hook
+  5  d2238cb6781d acpi: cpuhp: implement hot-add parts of CPU hotplug
+                  interface
+  6  8872c25a26cc acpi: cpuhp: implement hot-remove parts of CPU hotplug
+                  interface
+  7  76623d00ae57 acpi: cpuhp: add cpu._OST handling
+  8  679dd1a957df pc: use new CPU hotplug interface since 2.7 machine type
+
+Before patch#1, "docs/specs/acpi_cpu_hotplug.txt" only specified 1-byte
+accesses for the hotplug register block.  Patch#1 preserved the same
+restriction for the legacy register block, but:
+
+- it specified DWORD accesses for some of the modern registers,
+
+- in particular, the switch from the legacy block to the modern block
+  would require a DWORD write to the *legacy* block.
+
+The latter functionality was then implemented in cpu_status_write()
+[hw/acpi/cpu_hotplug.c], in patch#8.
+
+Unfortunately, all DWORD accesses depended on a dormant bug: the one
+introduced in earlier commit a014ed07bd5a ("memory: accept mismatching
+sizes in memory_region_access_valid", 2013-05-29); first released in
+v1.6.0.  Due to commit a014ed07bd5a, the DWORD accesses to the *legacy*
+CPU hotplug register block would work in spite of the above series *not*
+relaxing "valid.max_access_size = 1" in "hw/acpi/cpu_hotplug.c":
+
+> static const MemoryRegionOps AcpiCpuHotplug_ops = {
+>     .read = cpu_status_read,
+>     .write = cpu_status_write,
+>     .endianness = DEVICE_LITTLE_ENDIAN,
+>     .valid = {
+>         .min_access_size = 1,
+>         .max_access_size = 1,
+>     },
+> };
+
+Later, in commits e6d0c3ce6895 ("acpi: cpuhp: introduce 'Command data 2'
+field", 2020-01-22) and ae340aa3d256 ("acpi: cpuhp: spec: add typical
+usecases", 2020-01-22), first released in v5.0.0, the modern CPU hotplug
+interface (including the documentation) was extended with another DWORD
+*read* access, namely to the "Command data 2" register, which would be
+important for the guest to confirm whether it managed to switch the
+register block from legacy to modern.
+
+This functionality too silently depended on the bug from commit
+a014ed07bd5a.
+
+In commit 5d971f9e6725 ('memory: Revert "memory: accept mismatching sizes
+in memory_region_access_valid"', 2020-06-26), first released in v5.1.0,
+the bug from commit a014ed07bd5a was fixed (the commit was reverted).
+That swiftly exposed the bug in "AcpiCpuHotplug_ops", still present from
+the v2.7.0 series quoted at the top -- namely the fact that
+"valid.max_access_size = 1" didn't match what the guest was supposed to
+do, according to the spec ("docs/specs/acpi_cpu_hotplug.txt").
+
+The symptom is that the "modern interface negotiation protocol"
+described in commit ae340aa3d256:
+
+> +      Use following steps to detect and enable modern CPU hotplug interface:
+> +        1. Store 0x0 to the 'CPU selector' register,
+> +           attempting to switch to modern mode
+> +        2. Store 0x0 to the 'CPU selector' register,
+> +           to ensure valid selector value
+> +        3. Store 0x0 to the 'Command field' register,
+> +        4. Read the 'Command data 2' register.
+> +           If read value is 0x0, the modern interface is enabled.
+> +           Otherwise legacy or no CPU hotplug interface available
+
+falls apart for the guest: steps 1 and 2 are lost, because they are DWORD
+writes; so no switching happens.  Step 3 (a single-byte write) is not
+lost, but it has no effect; see the condition in cpu_status_write() in
+patch#8.  And step 4 *misleads* the guest into thinking that the switch
+worked: the DWORD read is lost again -- it returns zero to the guest
+without ever reaching the device model, so the guest never learns the
+switch didn't work.
+
+This means that guest behavior centered on the "Command data 2" register
+worked *only* in the v5.0.0 release; it got effectively regressed in
+v5.1.0.
+
+To make things *even more* complicated, the breakage was (and remains, as
+of today) visible with TCG acceleration only.  Commit 5d971f9e6725 makes
+no difference with KVM acceleration -- the DWORD accesses still work,
+despite "valid.max_access_size = 1".
+
+As commit 5d971f9e6725 suggests, fix the problem by raising
+"valid.max_access_size" to 4 -- the spec now clearly instructs the guest
+to perform DWORD accesses to the legacy register block too, for enabling
+(and verifying!) the modern block.  In order to keep compatibility for the
+device model implementation though, set "impl.max_access_size = 1", so
+that wide accesses be split before they reach the legacy read/write
+handlers, like they always have been on KVM, and like they were on TCG
+before 5d971f9e6725 (v5.1.0).
+

+Subject: [PATCH] tests/tcg/i386: Introduce and use reg_t consistently
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Define reg_t based on the actual register width.
+Define the inlines using that type.  This will allow
+input registers to 32-bit insns to be set to 64-bit
+values on x86-64, which allows testing various edge cases.

+Subject: [PATCH] target/i386: fix ADOX followed by ADCX
+
+When ADCX is followed by ADOX or vice versa, the second instruction's
+carry comes from EFLAGS and the condition codes use the CC_OP_ADCOX
+operation.  Retrieving the carry from EFLAGS is handled by this bit
+of gen_ADCOX:
+
+        tcg_gen_extract_tl(carry_in, cpu_cc_src,
+            ctz32(cc_op == CC_OP_ADCX ? CC_C : CC_O), 1);
+
+Unfortunately, in this case cc_op has been overwritten by the previous
+"if" statement to CC_OP_ADCOX.  This works by chance when the first
+instruction is ADCX; however, if the first instruction is ADOX,
+ADCX will incorrectly take its carry from OF instead of CF.
+
+Fix by moving the computation of the new cc_op at the end of the function.
+The included exhaustive test case fails without this patch and passes
+afterwards.
+
+Because ADCX/ADOX need not be invoked through the VEX prefix, this
+regression bisects to commit 16fc5726a6e2 ("target/i386: reimplement
+0x0f 0x38, add AVX", 2022-10-18).  However, the mistake happened a
+little earlier, when BMI instructions were rewritten using the new
+decoder framework.
