      Emanuele Giuseppe Esposito authored 
      
If we go directly to GLOBAL_STATE_CODE, IO_CODE or IO_OR_GS_CODE
definition, we just find that they "mark and check that the function
is part of the {category} API".
However, ther is no definition on what {category} API is, they are
in include/block/block-*.h
Therefore, add a comment that refers to such documentation.

The stderr spew is its own known issue, but seems like iotests should
be discarding stderr in this case.

      hw/block/hd-geometry: Do not override specified bios-chs-trans · fd8a68ad
      Lev Kujawski authored 
      For small disk images (<4 GiB), QEMU and SeaBIOS default to the
LARGE/ECHS disk translation method, but it is not uncommon for other
BIOS software to use LBA in these cases as well.  Some operating
system boot loaders (e.g., NT 4) do not handle LARGE translations
outside of fixed configurations.  See, e.g., Q154052:

"When starting an x86 based computer, Ntdetect.com retrieves and
stores Interrupt 13 information. . . If the disk controller is using a
32 sector/64 head translation scheme, this boundary will be 1 GB. If
the controller uses 63 sector/255 head translation [AUTHOR: i.e.,
LBA], the limit will be 4 GB."

To accommodate these situations, hd_geometry_guess() now follows the
disk translation specified by the user even when the ATA disk geometry
is guessed.

hd_geometry_guess():
* Only set the disk translation when translation is AUTO.
* Show the soon-to-be active translation (*ptrans) in the trace rather
  than what was guessed.

The value passed to strerror() should be positive.
So let's fix it.

      libvduse: Replace strcpy() with strncpy() · d9cf16c0
      Xie Yongji authored 
      
Coverity reported a string overflow issue since we copied
"name" to "dev_config->name" without checking the length.
This should be a false positive since we already checked
the length of "name" in vduse_name_is_invalid(). But anyway,
let's replace strcpy() with strncpy() (as a general library,
we'd like to minimize dependencies on other libraries, so we
didn't use g_strlcpy() here) to fix the coverity complaint.

In vduse_name_is_valid(), we actually check whether
the name is invalid or not. So let's change the
function name to vduse_name_is_invalid() to match
the behavior.

      Jinhao Fan authored 
      
The commit "Use io_uring_register_ring_fd() to skip fd operations" uses
warn_report but did not include the header file "qemu/error-report.h".
This causes "error: implicit declaration of function ‘warn_report’".
Include this header file.

Seventh RISC-V PR for QEMU 7.1

This is a second PR to go in for RC1. It fixes a bug we have had
for awhile, but it's a simple fix so let's pull it in for RC1.
