target/openrisc: Fix exception handling status registers
I am working on testing instruction emulation patches for the linux
kernel. During testing I found these 2 issues:
- sets DSX (delay slot exception) but never clears it
- EEAR for illegal insns should point to the bad exception (as per
openrisc spec) but its not
This patch fixes these two issues by clearing the DSX flag when not in a
delay slot and by setting EEAR to exception PC when handling illegal
instruction exceptions.
After this patch the openrisc kernel with latest patches boots great on
qemu and instruction emulation works.

qcow2: Optimize the refcount-block overlap check
The metadata overlap checks introduced in
a40f1c2add help detect
corruption in the qcow2 image by verifying that data writes don't
overlap with existing metadata sections.
The 'refcount-block' check in particular iterates over the refcount
table in order to get the addresses of all refcount blocks and check
that none of them overlap with the region where we want to write.
The problem with the refcount table is that since it always occupies
complete clusters its size is usually very big. With the default
values of cluster_size=64KB and refcount_bits=16 this table holds 8192
entries, each one of them enough to map 2GB worth of host clusters.
So unless we're using images with several TB of allocated data this
table is going to be mostly empty, and iterating over it is a waste of
CPU. If the storage backend is fast enough this can have an effect on
I/O performance.
This patch keeps the index of the last used (i.e. non-zero) entry in
the refcount table and updates it every time the table changes. The
refcount-block overlap check then uses that index instead of reading
the whole table.
In my tests with a 4GB qcow2 file stored in RAM this doubles the
amount of write IOPS.

block: check full backing filename when searching protocol filenames
In bdrv_find_backing_image(), if we are searching an image for a backing
file that contains a protocol, we currently only compare unmodified
paths.
However, some management software will change the backing filename to be
a relative filename in a path. QEMU is able to handle this fine,
because internally it will use path_combine to put together the full
protocol URI.
However, this can lead to an inability to match an image during a QAPI
command that needs to use bdrv_find_backing_image() to find the image,
when it is searched by the full URI.
When searching for a protocol filename, if the straight comparison
fails, this patch will also compare against the full backing filename to
see if that is a match.

block/vmdk: Fix the endian problem of buf_len and lba
The problem was triggered by qemu-iotests case 055. It failed when it
was comparing the compressed vmdk image with original test.img.
The cause is that buf_len in vmdk_write_extent wasn't converted to
little-endian before it was stored to disk. But later vmdk_read_extent
read it and converted it from little-endian to cpu endian.
If the cpu is big-endian like s390, the problem will happen and
the data length read by vmdk_read_extent will become invalid!
The fix is to add the conversion in vmdk_write_extent, meanwhile,
repair the endianness problem of lba field which shall also be converted
to little-endian before storing to disk.

using, we re-apply writes only to the first 1MB of the guest allocated
BDSM.
We can't assume either the host or guest BDSM is naturally aligned, so
we can't simply apply a different mask. Instead, save the host BDSM
and do the arithmetic to subtract the host value to get the BDSM
offset and add it to the guest allocated BDSM.

cirrus: fix patterncopy checks
The blit_region_is_unsafe checks don't work correctly for the
patterncopy source. It's a fixed-sized region, which doesn't
depend on cirrus_blt_{width,height}. So go do the check in
cirrus_bitblt_common_patterncopy instead, then tell blit_is_unsafe that
it doesn't need to verify the source. Also handle the case where we
blit from cirrus_bitbuf correctly.
This patch replaces
5858dd1801883309bdd208d72ddb81c4e9fee30c.
Security impact: I think for the most part error on the safe side this
time, refusing blits which should have been allowed.
Only exception is placing the blit source at the end of the video ram,
so cirrus_blt_srcaddr + 256 goes beyond the end of video memory. But
even in that case I'm not fully sure this actually allows read access to
host memory. To trick the commit
5858dd18 security checks one has to
pick very small cirrus_blt_{width,height} values, which in turn implies
only a fraction of the blit source will actually be used.

boot, and by using the "nvramrc" environment variable instead of
"boot-command", since this variable is evaluated earlier in the
boot process.
And to be really sure that we do not face such time out problems
again, let's also increase the time out value from 100s to 120s
instead.

the refactoring, it is now possible to specify a listen address for
the websocket server explicitly. e.g,
-vnc localhost:5900,websockets=0.0.0.0:8080
will listen on localhost for the plain VNC server, but expose the

ui: fix reporting of VNC auth in query-vnc-servers
Currently the VNC authentication info is emitted at the
top level of the query-vnc-servers data. This is wrong
because the authentication scheme differs between plain
and websockets when TLS is enabled. We should instead
report auth against the individual servers. e.g.
(QEMU) query-vnc-servers
{
"return": [
{
"clients": [],
"id": "default",
"auth": "vencrypt",
"vencrypt": "x509-vnc",

"websocket": true,

}
]

cope with multiple VNC server instances, listening on
different interfaces or ports, with different auth
setup.

vnc: do not disconnect on EAGAIN
When qemu vnc server is trying to send large update to clients,
there might be a situation when system responds with something
like EAGAIN, indicating that there's no system memory to send
that much data (depending on the network speed, client and server
and what is happening). In this case, something like this happens
on qemu side (from strace):
sendmsg(16, {msg_name(0)=NULL,
msg_iov(1)=[{"\244\"..., 729186}],
msg_controllen=0, msg_flags=0}, 0) = 103950
sendmsg(16, {msg_name(0)=NULL,
msg_iov(1)=[{"lz\346"...,
1559618}],
msg_controllen=0, msg_flags=0}, 0) = -1 EAGAIN
sendmsg(-1, {msg_name(0)=NULL,
msg_iov(1)=[{"lz\346"...,
1559618}],
msg_controllen=0, msg_flags=0}, 0) = -1 EBADF
qemu closes the socket before the retry, and obviously it gets EBADF
when trying to send to -1.
This is because there WAS a special handling for EAGAIN, but now it doesn't
work anymore, after commit
04d2529da27db512dcbd5e99d0e26d333f16efcc, because
now in all error-like cases we initiate vnc disconnect.
This change were introduced in qemu 2.6, and caused numerous grief for many
people, resulting in their vnc clients reporting sporadic random disconnects
from vnc server.
Fix that by doing the disconnect only when necessary, i.e. omitting this
very case of EAGAIN.
Hopefully the existing condition (comparing with QIO_CHANNEL_ERR_BLOCK)
is sufficient, as the original code (before the above commit) were
checking for other errno values too.
Apparently there's another (semi?)bug exist somewhere here, since the
code tries to write to fd# -1, it probably should check if the connection
is open before. But this isn't important.

Thumb-1 code has some issues in BE32 mode (as currently implemented). In
short, since bytes are swapped within words at load time for BE32

This patch un-swaps those pairs of instructions again, both for execution,

bytes in arm_read_memory_func and then extracted the proper two bytes,
in a probably misguided attempt to match the behaviour of actual hardware

rules: don't try to create missing include dirs
In
commit
ba78db44f6532d66a1e704bd44613e841baa2fc5
Author: Daniel P. Berrange <berrange@redhat.com>
Date: Wed Jan 25 16:14:10 2017 +0000
make: move top level dir to end of include search path
The dir $(BUILD_DIR)/$(@D) was added to the include
path. This would sometimes point to a non-existant
directory, if the sub-dir in question did not contain
any target-independant files (eg tcg/). To deal with
this the rules.mak attempted to create the directory.
While this was succesful, it also caused accidental
creation of files in the parent of the build dir.
e.g. when building common source files into target
specific output files.
Rather than trying to workaround this, just revert
the code that attempted to mkdir the missing include
directories. Instead just turn off the compiler warning
in question as the missing dir is expected & harmless
in general.
NB: you can clean up a build directory parent that has
been filled with empty directories by commit
ba78db44f653
using this GNU find command in that parent directory:
find audio backends block chardev crypto disas fsdev hw io linux-user \
migration nbd net qapi qom replay slirp target ui util \
-type d -empty -delete
