-RFE: Support spice via unix domain socket
-
-According to the man page, spice can be only used via TCP/IP in opposite to VNC, which can also be configured to listen on a unix domain socket. To make it easy to use spice without exposing the interface, please support unix domain sockets as well. I can try  to provide a patch, if you can point me to the source code where TCP/IP socket is opened.
-
-There is already support for that in spice-server afaik, though I don't remember the api or what commit, or if it's in a released version (well, it's surely in 0.11.0, but that's unstable). Sorry about the lack of details, I suggest you search spice-devel mailing list archive though. I think libvirt can already use it, but perhaps you want a commandline option, that may be missing.
-
-Alon
-
-you could pass sockets via QMP a while ago, but listening to unix socket has been added there:

-gdb can't proceed after a breakpoint
-
-Using qemu-1.0.1-windows.zip package from http://lassauge.free.fr/qemu/
-Host: Windows 7 Ultimate 64-bit
-Guest: i386 system running MS-DOS 6.22
-Launch command line:
-  qemu-system-i386.exe -L Bios -fda "DOS.vfd" -fdb "Data.vfd" -gdb tcp:127.0.0.1:1234
-Debbugers tried:
-  gdb 7.3.50.20111026-cvs running on Cygwin 1.7.16
-  gdb 7.4 on MinGW
-
-Short description:
-I use gdb to attach to a running Qemu session, set a breakpoint and resume execution. When the breakpoint is hit, gdb gains control as expected. However, trying to single-step or continue at this point just causes the same breakpoint to be hit immediately again. Deleting the breakpoint allows single-stepping or continue to work.
-
-Steps to reproduce:
-DOS.vfd is a floppy image containing an MS-DOS 6.22 startup disk.
-Data.vfd is a floppy image containing a single program (hello.com).
-The aim is to debug the execution of hello.com with gdb.
-Launch Qemu.
-Launch gdb, an attach to qemu:
-  "target remote localhost:1234"
-I know the address at which hello.com will be loaded, so set a breakpoint there and resume execution:
-  "break *0xf730"
-  "continue"
-In Qemu, start hello.com. The breakpoint is immediately hit, execution stops and gdb gains control.
-Examining the program gives expected results (such as "info reg" or "disassemble").
-At this point, try to proceed either with single-stepping ("si" or "ni") or with "continue", and the same breakpoint is immediately hit again. Subsequent attempts to single-step or continue just keep hitting the same breakpoint.
-The only way to proceed at this point is to delete the breakpoint, after which both single-stepping and continue work.
-
-Note that single-stepping and continue works as expected if it is done after interrupting execution with Ctrl-C.

-Hi,
-
-Thank you for your email, I remember this issue. Unfortunately I don’t have the time to try this right now, but I may be able to get to it in the next couple of weeks.

-Intel 12th Gen CPU not working with QEMU Hyper-V nested virtualization
-Description of problem:
-When booting with Hyper-V + host-passthrough it gets stuck at tianocore, does not change until I reboot which then loops into windows diagnostics which leads nowhere. Done using Windows 10, tried using newest windows version and 1909.
-
-Specs: Manjaro Gnome 5.15 LTS, i5-12600k, z690 gigabyte aorus elite ddr4, rtx 3070ti.
-
-I’ve spent days trying to figure out what was messing with it and it turned out I could boot when messing with my CPU topology, for some reason my 12th gen + Hyper-V + host-passthrough only works with sockets. Cores and threads above 1 causes boot problems, apart from disabling vme which boots, but the hypervisor does not load.
-
-This fails (normal host-passthrough):
-```
-  <cpu mode="host-passthrough" check="none" migratable="on">
-    <topology sockets="1" dies="1" cores="6" threads="2"/>
-  </cpu>
-```
-
-This boots (-can only change sockets):
-```
-  <cpu mode="host-passthrough" check="none" migratable="on">
-    <topology sockets="12" dies="1" cores="1" threads="1"/>
-  </cpu>
-```
-
-This boots (-no hypervisor):

-<cpu mode="host-passthrough" check="partial" migratable="off">
-    <topology sockets="1" dies="1" cores="6" threads="2"/>
-    <feature policy="disable" name="vme"/>
-  </cpu>
-```
-
-No matter what adjustment I do I cannot change the cores or threads or it will result in a boot failure, host-model just does not work once I boot the machine the host model changes to cooperlake.
-
-My current way of bypassing this is I’ve downloaded the QEMU source code, gone through cpu.c and modified the default skylake-client CPU model to match my CPU, then I added in most of my i5-12600k flags manually, this seems to work with a 35-45% performance drop in CPU and in ram. Without Hyper-V enabled and using the normal host-passthrough I get near bare metal performance.
-
-Tried with multiple versions of QEMU, EDK2, and loads of kernel versions (to add to this my i5-12600k gen does not work on kernel version 5.13 and below) even went ahead to try Ubuntu and had the same problem, my other (i7-9700k) PC works fine with Hyper-V. Also disabled my E-cores through bios resulting in the same issue. CPU pinning the P-cores to the guest does not seem to help.
-Steps to reproduce:
-1. Enable hyper-v in windows features
-2. Restart guest
-3. Boot failure

-QEMU does not close listening socket for incoming migration when post-copy migration breaks
-Description of problem:
-QEMU keeps listening on the incoming port even after breaking a post-copy
-migration using "migrate-pause" QMP command. And even once migration is
-finished after recovering it "migrate-recover" using a different port number.
-If "migrate-recover" is called with a URI specifying the original port (which
-is still in LISTEN state), QEMU reports "Failed to find an available port:
-Address already in use".
-Steps to reproduce:
-1. start migration
-2. wait for the first iteration to finish
-3. switch to post-copy using "migrate-start-postcopy"
-3. break migration with "migrate-pause"
-4. check lsof -p $QEMU_PID

-Feature request: tls for chardev socket (telnet,tcp,udp)
-
-Hello,
-
-it would be nice if chardev socket (telnet,tcp,udp) could have tls support as vnc does.
-
-This way we could have encrypted access to virtual character devices over network,
-for example in setup: conserver -> socat+tls <-> qemu+chardev+tls.
-
-The best would be both direction - server even client, so even the client should
-trust remote server (trustfile, fingeprint...?).
-
-Thank you.
-
-This support was introduced in QEMU 2.6 last year. Some info here:

-
-The following would be useful:
-  Good bytes receive counter GORCH/GORCL
-  Good bytes transmit counter GOTCH/GOTCL
-Broadcast packets sent/received
-Multicast packets sent/received.

-qemu dosn't save snapshots with the 'commit' command
-
-Usually there is the 'commit' command in qemu which is described as followed: "commit changes to the disk images (if -snapshot is used) or backing files"
-From the context i though if i start a guest with the "-snapshot" option, the commit command would save all the changes back to the file. I've tried it out but i didn't get it to work. I tried a few things like first use savevm or stop and than commit all, but actually nothing works.
-Interestingly, when using qcow2 files qemu doesn't show's any error at all. The changes in the guest just won't get saved. But if i'm using lvm2 partitions i would get I/O errors after execute 'commit all'. That's probably because lvm2 doesn't support this feature.?!? However i made a attachment which shows the error's in the guest (dmesg).
-
-Right now i started the guest with following command:

-socket type mapping wrong for mips app-level emulation
-
-linux-user/syscall.c's do_socket function contains socket type remapping to work around the nonsensically-permuted MIPS socket types. However, it fails to account for the SOCK_NONBLOCK and SOCK_CLOEXEC flags that may be or'd onto the type. Thus, a call from the application such as:
-
-socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)
-
-will fail to have the type permutation performed, and will be passed to the system as:
-
-socket(AF_INET, SOCK_DGRAM, IPPROTO_TCP)
-
-resulting in EPROTONOSUPPORT.
-
-To fix this, the flag bits should be masked off of the type before the permutation. They also need remapping themselves (since MIPS uses different values for these flags bits).
-
-This should be fixed in QEMU 1.6.

-linux-user emulation of setsockopt ignores optlen
-
-setsockopt always treats the argument as a 4-byte int. This breaks timeout options (for which it's an 8- or 16-byte timeval structure, depending on word size) and possibly other socket options. int is probably a safe default, but options whose values are other types need special-case conversion code.
-
-Agreed; we would ideally be more careful to return ENOTSUP for options we don't know we handle correctly. It would be useful if you said which particular options you were interested in and provided a test case...
-
-
-I mentioned the timeout options (send/receive timeout) which are the
-ones I was interested in.
-
-
-We fixed our setsockopt emulation to correctly convert timeval parameters for SO_RCVTIMEO and SO_SNDTIMEO back in 2013.

-MC146818 RTC breaks when SET bit in Register B is on.
-
-This bug occurs when the SET flag of Register B is enabled. When an RTC
-data register (i.e. any of the 10 bytes of time/calender data in CMOS) is set,
-the data is (as expected) correctly stored in the cmos_data array. However,
-since the SET flag is enabled, the function rtc_set_time is not invoked.
-As a result, the field base_rtc in RTCState remains uninitialized. This appears to
-cause a problem on subsequent writes which can end up overwriting data.
-
-To see this, consider writing data to Register A after having written
-data to any of the RTC data registers; the following figure illustrates
-the call stack for the Register A write operation:
-
- +- cmos_io_port_write
- +-- check_update_timer
- +---- get_next_alarm
- +------ rtc_update_time
-
-In rtc_update_time, get_guest_rtc calculates the wrong time and
-overwrites the previously written RTC data register values.
-
-I have created a standalone test case which exposes this bug:
-
-   https://github.com/ahorn/benchmarks/commit/fff1ca40694bbef6f7f9de323bb0bed63419ef99
-
-I have attached a patch for the most recent version of the file hw/mc146818rtc.c [1]. The patch also features a functional test which executes through the QTest framework.

-> 1) please test == 0, not != REG_B_SET;
-> 2) please leave the fuzzicsng test last
-
-I have attached a new patch with the requested changes.
-
-This patch also improves the quality of the functional test by
-checking that RTC_SECONDS is equal (==) to the previously written data
-provided the SET flag in Register B is still enabled. This is
-justified by the data sheet which states that an enabled SET bit
-"stops an existing update" and prevents "a new one from occurring" [1,
-p. 15]. In contrast, once the SET flag is disabled, the RTC_SECONDS
-check uses an inequality (>=) as in the original test case.

-Out of curiosity, does anyone know how long this particular bug has
-been undetected or how/when it was introduced? This could help me
-explain to others my research interest in symbolic execution of
-hardware models and its application in form of automated test

-
-Finally, if there is interest to improve the robustness of the RTC
-model, I could send a patch with several verification conditions (i.e.
-assertions) which can help to expose these kind of bugs in the RTC
-hardware model. Recall that most compiler can usually optimize these
-assertions away unless a developer explicitly enables them. They also
-serve as unambiguous code documentation.
-

-> Very interesting (at least to me :)).
-
-Perhaps you find the following background helpful. To kick start our
-work, we extracted from QEMU a standalone RTC hardware model [2]
-because QOM, QMP, TCG or QTest would render the semi-automatic
-analysis infeasible. As a next step, we would like to combine this
-standalone hardware model with a Linux x86 driver [3]. The reported
-bug is a good exemplar of the type of firmware/hardware interface

--serial tcp should hang up when DTR goes low
-
-In keeping with the spirit of serial modem control signals, de-asserting DTR should cause the TCP connection to break; asserting DTR should cause QEMU to initiate a new connection or for it to accept another (in server mode; this may involve waiting for one to arrive, too).
-
-In addition to allowing low DTR to drop the socket connection, and allowing low DTR to reject a socket connection, the DCD modem bit also be implemented - DCD should follow the state of the TCP socket: a connected socket should pull DCD high, and a disconnected socket should pull DCD low. From what Ive seen in the source, it looks like a serial IOCTL functioned needs to be added to chardev/char-socket.c to allow the MSR bits to be tracked against the state of the socket.  DCD should be very easy to implement this way, but I hadn't thought about DTR.
-
-Sent in a patch for this.
-
-https://lists.gnu.org/archive/html/qemu-devel/2020-12/msg04658.html
-
-DTR controls the socket.
-
-DCD reflects the state of the socket.

-e1000 nic TCP performances
-
-Hi,
-
-Here is the context :
-
-$ qemu -name A -m 1024 -net nic vlan=0,model=e1000 -net socket,vlan=0,listen=127.0.0.1:7000
-$ qemu -name B -m 1024 -net nic vlan=0,model=e1000 -net socket,vlan=0,connect=127.0.0.1:7000
-
-The bandwidth is really tiny :
-
-    . Iperf3 reports about 30 Mb/sec
-    . NetPerf reports about 50 Mb/sec
-
-
-With UDP sockets, there is no problem at all :
-
-    . Iperf3 reports about 1 Gb/sec
-    . NetPerf reports about 950 Mb/sec
-
-
-I've noticed this fact only with the e1000 NIC, not with others (rtl8139,virtio, etc.)
-I've used the main GIT version of QEMU.
-
-
-Thanks in advance.
-
-See you,
-VInce

-It's interesting that you see good performance over -netdev socket TCP
-with the other NIC models.
-
-I don't know what the issue would be, you'll probably need to dig
-further to discover the problem.  Using wireshark might be a good start.
-Try to figure out where the delay is incurred and then instrument that

-===================
-
-If I use rng-random backend (filename=/dev/random), the speed is about 350k/s).
-
-It seems that when the request entry is added to the list, we don't read the data from queue list immediately.
-The chr_read() is delayed, the virtio_notify() is delayed.  the next request will also be delayed. It effects the speed.

-DistroRelease: Ubuntu 14.04

-ProcVersionSignature: User Name 3.13.0-43.72-generic 3.13.11.11

-Date: Tue Jan 13 14:30:39 2015
-SourcePackage: qemu
-UpgradeStatus: No upgrade log present (probably fresh install)
-
-
-
-Status changed to 'Confirmed' because the bug affects multiple users.
-
-Workaround is to 'fallocate'. Problem seems to be linked to files with sparse holes in them. 
-
-
-
-verified this fails as described on vivid:
-$ dpkg-query --show qemu-utils
-qemu-utils	1:2.1+dfsg-11ubuntu1
-
-and also on trusty.
-
-$ dpkg-query --show qemu-utils
-qemu-utils	2.0.0+dfsg-2ubuntu1.10
-
-
-Does it also fail with the qemu from
-https://launchpad.net/~ubuntu-virt/+archive/ubuntu/virt-daily-upstream ?
-(This isn't quite git head, but it is qemu v2.2)
-
-
-Went ahead and tested - it is in fact fixed in the v2.2 version.
-
-qemu is 2.5 in 16.04 and 2.6.1 in Zesty, so this is presumably Fix Released now. If incorrect, please explain and reopen.

-Yes, this is a known issue which I can reproduce using a Solaris installation. I still have a few outstanding bugs on my list to do before I can start looking into this one, but I will keep this bug up to date as/when I can start work on it - apologies for not being able to be more specific than this at the moment.

-Hi all,
-I also have this issue with my sparcstation installation :
-
-Emulated OS				: 	SunOS 5.5.1
-Emulated Processor			: 	sparc
-Host machine OS			:	Linux RED HAT
-
-Do you manage to fix it ?
-
-Not yet - things have been made much harder now as my original test image tends to hang for long periods of time instead of giving the MUTEX_HELD error. If you have an image that you would be willing to share for debugging, please get in touch via email and I'll try and take a look.

-I already forgot the old one: I got a 2.3.0 qemu installed on the RHEL 5.3 machine, and since this machine has more disk spaces than the CentOS6.4 (now 6.6), so I copied again all emulated machine images from CentOS to RHEL machine, and started to build a new one for RHEL7.1 LE for Power on the 2.3.0, and found it's working quite well, and also other emulated machines are all working fine (mips32, mips32el, mips64el, armv7) on the 2.3.0.Then I just tried to use the RHEL5.9 Power qemu machine, but found root filesystem corrupted, copied from OS image from CentOS, start the qemu machine, again, root filesystem damaged. So, I created the bug report,  didn't think about old bug report I made. So, now it's clear, it's on the RHEL5.3 machine, multiple qemu versions have issue with RHEL5.9 for power.

-I built 2.3.0 on CentOS 6.6 machine, and run the RHEL5.9 using the new qemu-system-64 ,and gets the same issue as 2.3.0 on RHEL5.3:
-
-Checking filesystems
-Checking all file systems.
-[/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a /dev/sda5
-/: Resize inode not valid.
-
-/: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
-        (i.e., without -a or -p options)
-[FAILED]
-
-As I stated before on the CentOS6.6, the qemu 1.5.3 running the RHEL5.9 for power is ok. That proves it's not because of RHEL5.3 machine that fs is corrupted, it's the newer qemu for power emulation has issue to run big-endian version of RHEL.
-
-Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays?
-
-It seems to me that no one has really looked into the matter, I can't find any comments,that this issue has been worked on.

-Hi. Thanks for this bug report and the patch. In order
-for us to be able to use your patch, we'll need you to
-provide a signed-off-by line, which tells us you have
-the legal right to submit it and are happy for us to

-(You can look at

-if you want more details.)
-
-You can provide a signoff just by replying to this email
-with a line which reads
-"Signed-off-by: Your Name <your.email@here>".
-
-A couple of notes: this bug only affects boards which
-have a write_board_setup function, which means only
-highbank/midway, raspi2, and xilinx_zynq; that's probably
-why we didn't spot it earlier.

-I'm unable to reproduce the problem mentioned myself, and code inspection shows no problem for x86_64 at least.
-
-Specifically hw/char/serial.c has a   serial_xmit() method which calls qemu_chr_fe_write(), and if it sees EAGAIN, it sets up a event notification to re-try the write later.
-
-Can you provide the full QEMU command line you are using, include the emulator binary.
-
-Looking at the code in 2.5.0, the qemu_chr_fe_write method would see EAGAIN too, because the tcp_chr_accept() method would always set the newly connected client to non-blocking mode. So thre's no obvious change in behaviour between 2.5 and 2.6 wrt to blocking sockets.
-

-
-It looks like tcp_chr_accept function isn't called in above command.
-tcp_chr_wait_connected function is called instead.
-
-So the socket is blocking mode and doesn't return EAGAIN in Qemu 2.5.0.
-
-Ok, now it makes more sense. You are using the socket chardev in TCP outgoing client mode, which used to be blocking by default. In 2.6 this switched to match TCP server mode,  in wich the incoming client was always in non-blocking mode. 
-
-IOW, this arm code was already broken in 2.5 just depending on which chardev config was used.
-
-So, we'll need to put a fix in pl011_write.  I'm unsure whether use writeall() is the correct behaviour - I'll come to other serial backends.

-qom-[list,tree,get,set] don't accept tcp endpoint arg
-
-Hi, 
-
-I'm using origin/master [6bbbb0ac13...]. When I run any of the commands in 'qemu/scripts/qmp/qom-[list,tree,get,set]', the help text says that it can connect to a QEMU instance by passing either a path to a unix socket or a tcp endpoint in the format "host:port". The unix socket variant works but the tcp endpoint variant does not. QEMUMonitorProtocol accepts either a string (unix socket) or a tuple (host,port). None of the qom-* scripts actually massage the '-s' argument into a tuple. 
-
-I have a patch to fix this issue that I can submit to the developer list.
-
-Hi! Triaging old bug tickets ... is this still an issue with the latest version of QEMU? If you've got a patch for this ready, please send it to the qemu-devel mailing list!

-This is not the only place where we assemble a string from
-QEMU_VERSION QEMU_PKGVERSION, so if you want to change from the
-original approach where QEMU_PKGVERSION had a space in it then
-you need to change the other places too.

-
-I think when I wrote those printfs I was expecting that

-Support Python 3 to build
-
-Currently qemu's configure requires Python 2 to build.  As Python 2 is rapidly approaching its EOL, it should be possible to build qemu with Python 3.
-
-Python 2 EOL is in 2020 so there is a fair amount of time.
-
-QEMU is transitioning to support both Python 2.6+ and 3 but most Python code has not been converted yet.
-
-You are welcome to contribute patches:
-https://wiki.qemu.org/index.php/Contribute/SubmitAPatch
-
-> Python 2 EOL is in 2020 so there is a fair amount of time.
-
-Not as much time as you might think. Even well before that time, any new releases of long life and/or enterprise distros are likely to choose to skip py2 by default, as it will be EOL long before the distro itself EOLs.

-armeb regression since qemu version 2.8
-
-Hi,
-
-I have noticed a regression when I upgraded from qemu-armeb 2.7 to 2.8, and the problem is still present with version 2.10.1.
-
-I am using qemu for GCC validation, noticed problems with testcases involving atomics, I'm attaching here atomic-exchange-4.exe.
-
-# with 2.7:
-$ qemu-armeb -cpu any -R 0 -L $PWD -E LD_LIBRARY_PATH=$PWD/lib $PWD/atomic-exchange-4.exe
-$ echo $?
-0
-# with 2.8, 2.10.1:
-$ qemu-armeb -cpu any -R 0 -L $PWD -E LD_LIBRARY_PATH=$PWD/lib $PWD/atomic-exchange-4.exe
-qemu: uncaught target signal 6 (Aborted) - core dumped
-Aborted (core dumped)
-$ echo $?
-134
-
-The source code is gcc/testsuite/gcc.dg/atomic-exchange-4.c
-
-Running with -d in_asm shows a difference early in the startup code:
-IN: _dl_sysdep_start
-[...]
-0x40a17790:  908ff103      addls	pc, pc, r3, lsl #2
-
-and then the next address is not the same with qemu 2.7 and 2.10.1
-
-I hope you have enough data/information to reproduce and confirm/fix the problem.
-
-Thanks
-
-
-
-
-
-
-
-Hi Christophe -- RTH posted a patchset yesterday which should fix this:
-https://lists.gnu.org/archive/html/qemu-devel/2017-10/msg04809.html
-
-
-Oh, wait, different bug. Sorry for the noise...
-
-
-I rather suspect something is going wrong when the dynamic loader attempts to paw through the ELF auxiliary vector...
-
-
-Ah, that's a false positive. We flipped the order we put entries in the AUXV in commit 7c4ee5bcc82e64, so the code divergence is just because now _dl_sysdep_start is processing the entries in the opposite order to what it used to. (The "addls pc, pc, r3, lsl #2" is jumping into the jump table for the switch on different AUXV entry tags.) The traces converge again at 0x40817830.
-
-
-I think what's actually happening is that we're failing on one of the tests in main(). This would be much easier to diagnose if the test case code printed information about what it was doing and what the failed test case was...
-
-
-Indeed I wish GCC tests printed information rather than just calling abort()...
-
-I'll add some printfs and see what this says.
-
-
-I added printfs after each 'count++' statement, and here is what I got:
-
-qemu-2.7:
-ATOMIC_RELAXED OK
-ATOMIC_ACQUIRE OK
-ATOMIC_RELEASE OK
-ATOMIC_ACQ_REL OK

-qemu for windows fails to use multicast socket as netdev
-
-My host OS is Windows 7 x64 SP1. I installed qemu for windows from https://qemu.weilnetz.de/w64/.The version is 2.10.1, qemu-w64-setup-20171006.exe. I run qemu with the following command:
-
-qemu-system-x86_64.exe -net nic -net socket,mcast=234.5.5.5:6000 disk1.qcow2
-
-It stopped with error:
-bind: Unknown error
-qemu-system-x86_64.exe: -net socket,mcast=234.5.5.5:6000: Device 'socket' could not be initialized
-
-Using the -netdev option has the same problem:
-qemu-system-x86_64.exe -netdev socket,id=hostnet0,mcast=234.5.5.5:6000 -device e1000,netdev=hostnet0 disk1.qcow2
-
-I tried many versions from https://qemu.weilnetz.de/w64/, but none of them could work.
-
-When I checked the source code, I think the problem is that on Microsoft Windows bind() can not use a multicast address.
-
-MSDN bind() reference
-https://msdn.microsoft.com/en-us/library/windows/desktop/ms737550(v=vs.85).aspx
-seems to have indicated the point.
-
-I changed the net_socket_mcast_create() in net/socket.c, make it bind to htonl(INADDR_ANY). After compiling, it seems to work correctly.
-
-Have you ever tried to suggest your change as a patch to the qemu-devel mailing list? See:
-https://wiki.qemu.org/Contribute/SubmitAPatch

-qemu8-user on Linux: SIGSEGV because brk(NULL) does not exist
-Description of problem:
-On Linux, the return value of the system call brk(NULL) need not point to a page that exists.
-If so, then qemu8-user will generate SIGSEGV at the next call to brk() with a higher value,
-because qemu8 believes that it should maintain contiguous .bss with bytes of value 0.
-Thus qemu8-user so calls `memset(g2h_untagged(target_brk), 0, brk_page - target_brk);
-in do_brk() at ../linux-user/syscall.c:867, and this generates SIGSEGV at
-the non-existent page that covers brk(NULL).
-
-Instead, the safest thing to do is nothing at all.
-Linux deliberately returns a random value for brk(NULL), subject to the conditions
-that the value be at least as large as the maximum over all PT_LOAD of (.p_vaddr + .p_memsz),
-and "somewhat near" that maximum.  The purpose of randomness is to use variability
-to interfere with effectiveness of malware, and to expose application coding errors
-regarding brk() and sbrk().  If qemu-user wants to preserve contiguous .bss,
-then qemu-user should call memset() only if the first page of the range exists.
-(As explained in the next paragraph, "contiguous .bss" is a murky concept.)
-
-Linux itself is partly to blame, because it computes the maximum (.p_vaddr + .p_memsz)
-over all the PT_LOAD of the most recent execve().  The most recent execve() seen by
-Linux might have no relationship to the state of the address space at the time of
-_either_ call to brk().  The app can do arbitrary mmap, munmap, mprotect at any time.
-In particular, the run-time de-compressor of UPX does exactly that for a compressed
-main program.  The maximum computed by Linux is for the compressed program,
-which has a different layout than the de-compressed program.
-
-There is a Linux system call prctl(PR_SET_MM_BRK, new_value) which sets a value
-for "the brk", but that syscall tries to validate the new_value based on
-the most recent execve().  Once again, that has no relationship to the current
-layout of the address space produced by the UPX de-compressor.
-Steps to reproduce:
-1. build qemu8-x86_64 from
-```
-commit fcb237e64f9d026c03d635579c7b288d0008a6e5 (HEAD -> master, origin/master, origin/HEAD)

-(It is necessary use SS-20 since it is the only sun4m model that supports 512MB RAM, and I can't get Solaris to install on the SS-20 using OpenBIOS.) 
-
-When booting with OpenBIOS I can't seem to boot any version of Solaris though I had heard this did work.  Solaris 8 and 9 do work nicely with this ROM, but I am opening this to see if it is possible to fix this to allow the original OBP ROM to see multiple processors.
-
-As of QEMU 4 OpenBIOS can boot Solaris again, and it does properly allocate multiple CPUs. Of course, it's a whole lot slower on multiple CPUs which I wasn't really anticipating, but it does work.  (And single CPU is so fast anyway compared to the actual hardware it's emulating!)  So this bug while still applicable can be closed. 
-
-The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
-If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.

-Reporter said in comment #1 that the bug can be closed, so let's close it :-)
-
-
-Yes this can be closed, no problems now using open bios to boot Solaris and it does support multiple processors though this is actually slower than one.

-QEMU ignores all but the first control message sent over a Unix socket
-
-I've written a test program that sends both an SCM_CREDENTIALS and an SCM_RIGHTS cmsg in the same sendmsg call. On native x86-64, armv6 and armv7 Linux, this works as expected (the recvmsg receives both control messages). On QEMU (both qemu-x86_64 and qemu-arm), only the first message is received.
-
-I've traced the problem back to a glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=13500
-
-This means that writing control messages into an uninitialized buffer makes CMSG_NXTHDR erroneously return NULL even though there's still space inside the allocated buffer. QEMU's logic inside `target_to_host_cmsg` is a bit questionable here, since it stops encoding cmsgs as soon as *either* the host or the target buffer reaches its end, so we lose the target's cmsgs when the host's buffer runs out. However, the host buffer should *never* reach its end before the target buffer does, so an assertion might be more useful there. Anyway, the actual fix for this bug is simply zeroing out the buffer created for the host. I've attached a patch doing that and verified that it fixes the issue.

-ioctl SIOCGIFCONF causes qemu-aarch64-static to crash with "received signal outside vCPU context"
-
-To reproduce it, compile the attached crash.c under aarch64 to a.out and execute on x86_64
-qemu-aarch64-static ./a.out
-
-It will print the following and crash:

-qemu-aarch64 version 3.0.0 (qemu-3.0.0-1.fc29)
-Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers
-
-But it did also happen in previous versions so it is not a regression but a bug existed ever since.
-
-
-
-I was hit by this issue when I tried to run some Java program. And it turns out jdk sets the buf to NULL: http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/887e525597f8/src/solaris/native/java/net/NetworkInterface.c#l1042
-
-Setting to NULL is valid according to http://man7.org/linux/man-pages/man7/netdevice.7.html
-
-But qemu doesn’t handle the case: https://github.com/qemu/qemu/blob/aa8e26de9617756febcbf794dda965df307fdaaa/linux-user/syscall.c#L4105
-
-I guess qemu developers didn’t handle the case because the Linux kernel changed and they were based on behavior of old version: https://linux.die.net/man/7/netdevice
-
-Please add the support for it otherwise a wide range of network related Java programs won’t run.
-
-I sent out a patch: http://lists.nongnu.org/archive/html/qemu-devel/2018-10/msg01657.html
-(Please ignore the other 2 identical patches. It was my first time sending out patches and I didn't know it was moderated so I sent it out multiple times).
-
-I have patch at http://lists.nongnu.org/archive/html/qemu-devel/2018-10/msg05401.html, please let me know when it can be merged, thanks.
-
-Kan Li's patch was applied to master as commit 22e4a267a6627e5b5b, so this will be fixed in the upcoming QEMU 4.0 release.

-default memory parameter too small on x86_64 today
-
-Launching a centos7 VM today does not work anymore on x86_64 without increasing the size of the memory parameter. For example with this command :
-
-$ /opt/qemu-3.0.0/bin/qemu-system-x86_64 --curses   -enable-kvm -drive file=file.dd,index=0,media=disk -drive file=centos-x86_64.iso,index=1,media=cdrom

-[    3.049258] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-693.21.1.el7.x86
-
-
-
-Increasing the size from the default 128MiB to 512MiB let the VM works without problem.
-So, ok, it's not a qemu problem, it's more a "User problem" and interface problem for me.
-But it push me in the end to launch VirtualBox instead of qemu, because the default parameter does not work anymore... And I had no time to investigate why it does not work because the message is not visible.
-Debian iso with the same command line for example show a message to tell me that there is not enough memory, so it help me to track the real issue behind.
-
-But... In the end, I think today, the default memory parameter on x86_64 is too small and it can lead some people like me to switch to VirtualBox.
-VirtualBox, in the wizard is set by default to 4MiB Ram size, which tell you... Ok I need to put more. But, you know that 4MiB is not enough in the end.

-IMHO, if achieving ease of use comparable to VirtualBox is your benchmark target, then launching QEMU directly is really the wrong way to approach things. QEMU is a very low level piece of infrastructure not a complete end user desktop solution. For that it is better to look at using an application such as virt-manager, or GNOME Boxes. These provide higher level solution over QEMU and do smart things during installation, using libosinfo to automatically determine the best memory, disk, network, etc settings for each particular guest OS rather than relying on some hardcoded defaults.
-
-That said all said, I don't rule out that we could change our memory defaults, but picking an optimal value is hard. Even 500 MB is considered to be unsupported from a RHEL-7 pov - the documented minimum for RHEL-7 is 1 GB per vCPU. The installer is quite likely to crash with 500 MB depending on what options you select durin intsall.

-Hi Daniel,
-
-I use qemu for a long time now so for me it's easier to use than any other
-solution.
-I think I began to use as my preffered VM tool in 2003.
-But, I still think that keeping this value at 128MB is low today.
-Maybe in this case reducing this value to make it crash is another option,
-for example 4MB.
-Or just print a message if it is an iso file that ramsize is set to 128MB,
-maybe you need more ram.
-It is just quick thought, some OS will handle this correctly, some os won't.
-For example in my example I say that debian say it explicitely in the 80x25
-screen in red.
-
-Today I see all people around me are moving to VirtualBox because it just
-work out of the box.
-And Qemu is near to work out of the box with 2 or 3 parameter in the end.
-Definitely I have a prefference for Qemu, because it's more "shell
-friendly".
-
-It was just my quick thought about it.

-The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
-If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.

-QEMU mishandling of SO_PEERSEC forces systemd into tight loop
-
-While building Debian images for embedded ARM target systems I detected that QEMU seems to force newer systemd daemons into a tight loop.
-
-My setup is the following:
-
-Host machine: Ubuntu 18.04, amd64
-LXD container: Debian Buster, arm64, systemd 241
-QEMU: qemu-aarch64-static, 4.0.0-rc2 (custom build) and 3.1.0 (Debian 1:3.1+dfsg-7)
-
-To easily reproduce the issue I have created the following repository:
-https://github.com/lueschem/edi-qemu
-
-The call where systemd gets looping is the following:
-2837 getsockopt(3,1,31,274891889456,274887218756,274888927920) = -1 errno=34 (Numerical result out of range)
-
-Furthermore I also verified that the issue is not related to LXD.
-The same behavior can be reproduced using systemd-nspawn.
-
-This issue reported against systemd seems to be related:
-https://github.com/systemd/systemd/issues/11557
-
-As described on the systemd issue, the syscall we're getting wrong here is getsockopt(fd, SOL_SOCKET, SO_PEERSEC, ...). Our linux-user/syscall.c:do_getsockopt() doesn't have any special case code for the payload on this function, so we treat it as if it were just an integer payload, which is not correct here.
-
-Unfortunately I can't find any documentation on exactly what SO_PEERSEC does or what the payload format is, which makes it pretty hard to fix this bug :-( It's not listed in the socket(7) manpage -- https://linux.die.net/man/7/socket -- which is where I'd expect to find it, and the kernel source code is pretty confusing in this area.
-
-
-This is probably the tight loop that gets triggered:
-https://github.com/systemd/systemd/commit/217d89678269334f461e9abeeffed57077b21454
-
-It looks like the previous implementation was just a bit more "tolerant".
-
-I have just studied a bit the systemd code and this brought me to the following idea/temporary workaround: What about returning -1 (error) and setting errno when getsockopt(fd, SOL_SOCKET, SO_PEERSEC, ...) gets called? This would then let systemd know that SO_PEERSEC is not (yet) implemented.
-
-I filed the duplicate #1840252 of this bug.
-
-I think that the options SO_PEERCRED and SO_PEERSEC belong into the context of SELINUX. So maybe the format of the paylod can be found in the sources of libselinux?
-
-I'd like to compile qemu with a local hack to work around my current problem. Something like Matthias Lüscher suggested. 
-
-@Peter Maydell: could you point me to the location in the qemu source where I could apply such a hack?
-
-I patched linux-user/syscall.c (see below, branch stable-2.11) which works around my problem.
-So far so good, but the qemu-arm that i compiled is terribly slow compared to the one that came with Ubuntu 18.04. Any hints?
-I configured as this:
-./configure --static --enable-kvm --target-list=arm-linux-user

-I'm a bit surprised that this bug doesn't get more attention, as it makes it very hard to run qemu-emulated containers of Bionic hosted on Bionic. Running such containers is a common way to cross-compile packages for foreign architectures in the absence of sufficiently powerful target HW.
-
-The documentation on SO_PEERSEC is indeed sparse, but I do want to second Fritz in his approach. I don't see a reason, why treating the payload as incorrect and throwing it back at the application is better than handling it and saying it is not implemented (which is the case).
-
-Arguably, applications should be fixed to handle the error correctly, but I'm afraid that is a can of worms. I have encountered the same problem with systemd, apt and getent. Would the maintainers be open to an SRU request on QEMU for this?
-
-Could you test the attached patch?
-
-Thanks, Laurent! I'll get back to you, asap.
-
-> Could you test the attached patch?

-
-Works great!
-
-This is my test setup:
-
-Host machine: Ubuntu 18.04, amd64
-LXD container: Debian Buster, arm64, systemd 241
-QEMU: qemu-aarch64(-static), compiled from source (4.2.0), patched with
-your patch.
-
-Many thanks!
-Matthias
-
-
-I carried out the following test:
-
-* fetched the QEMU coming with 18.04,
-* added this patch,
-* built an LXD container with arch arm64 and the patched qemu-aarch64-static inside,
-* launched it on amd64
-
-Previously various systemd services would not come up properly, now they are running like a charm. The only grief I have is that network configuration does not work, but that is due to
-
-    # ip addr
-    Unsupported setsockopt level=270 optname=11
-
-which is a different story.
-
-Well, it's kind of irrelevant but I am trying that on archlinux and this does not work for me.
-
-Using systemd-244.2-1 and qemu-user-static-4.2 that I built with Laurent's patch. May be I have done something wrong ?
-
-I still get that error that leads me here:
-
-Failed to enqueue loopback interface start request: Operation not supported
-Caught <SEGV>, dumped core as pid 3.
-Exiting PID 1...
-
-I am trying to boot with systemd-nspawn an archlinux-arm built for a rpi0. That's fine if I don't boot it.
-
-Laurent's patch worked for me as well.
-
-I grabbed the source for the Debian 10 qemu-user-static package, qemu_3.1+dfsg-8+deb10u3, applied the patch and re-built the qemu-arm-static binary. Copying the new binary into a Docker image based on arm32v7/debian:10-slim allowed /sbin/init to bring up the container with a responsive systemctl command.
-
-Prior to the patch, systemd did not start any services inside the container and systemctl would hang when executed directly.
-
-Thanks!

-SO_PEERGROUPS is not implemented and processed as an "int" (this explains the ERANGE)
-
-Could you try the attached patch?
-
-In my case the issue with using Ubuntu 20.04 as a container host appears to have come down to the use of the F, or "fix binary", flag by binfmnt_misc:
-
-# cat /proc/sys/fs/binfmt_misc/qemu-aarch64
-enabled
-interpreter /usr/bin/qemu-aarch64-static
-flags: OCF
-offset 0
-magic 7f454c460201010000000000000000000200b700
-mask ffffffffffffff00fffffffffffffffffeffffff
-
-This appears to be new in Ubuntu 20.04 relative to 18.04 and results in the qemu-user-static binaries being loaded and locked into memory _when the package is installed_.
-
-Therefore, what I observed as a regression of the issue was actually just the packaged binaries now taking precedence over patched versions that I had built and copied into place.
-
-Ubuntu 20.04 ships QEMU 4.2. Using the QEMU 5.1 packages from Debian Bullseye allows SystemD to run in a foreign architecture container without spinning in a loop:

-Request to add something like "Auth failed from IP" log report for built-in VNC server
-
-In environment with needs of public accessible VNC ports there is no logs or other registered events about authentication failures to analyze and/or integrate it to automated services like fail2ban ans so on.
-Thus the built-in VNC service is vulnerable to brutforce attacks and in combination with weak built-in VNC-auth scheme can be a security vulnerability.
-
-Adding a simple log record like "QEMU VNC Authentication failed 192.168.0.5:5902 - 123.45.67.89:7898" will permit to quickly integrate it to fail2ban system.
-
-Note that any use of the built-in VNC-auth scheme is always considered a security flaw. It should essentially never be used, especially not on any public internet facing service, even if fail2ban were able to be used.
-
-A secure VNC server should use the VeNCrypt extension which enables TLS, with optional client certificate validation as an auth mechanism.  Once you have TLS enabled, you can also then enable the SASL auth mechanism to further authenticate clients using Kerberos or PAM, or other SASL plugins.
-
-That's not to say we shouldn't emit a log message, suitable for consuming from fail2ban, as remote clients can still trigger a CPU denial of service by repeatedly connecting even if they ultimately always fail authentication.

-
-Should we deprecate-and-remove the feature, then ?
-

--- PMM
-
-
-The challenge is that this is the only auth scheme defined by the VNC protocol, aside from no-auth.
-If we removed it, we'd no longer be compatible with the standard VNC protocol. We'd be making use of the TLS/SASL extensions mandatory if users want auth. This could ultimately push people to turn off auth altogether which is even worse.

-Chardev websocket might not support pasting more than a few chars
-
-When sending more than 4-5 characters on the websocket serial console (with pasting for example), the guest might not receive all of them, or worse interpret the input as Magic SysRq keys.
-
-This might be due to the io loop not checking the backend readiness before calling the read function.
-
-Attached patched fixes the problem on my system. I'm not sure it's the proper approach, this is just to start discussion.
-
-
-
-If the problem only happens with a websockets channel enabled, it possibly a bug in the QIOChannelWebsock impl rather than the chardev
-
-I wrote a websocket client to help reproduce the bug without a browser:
-https://github.com/anisse/websocktty
-
-You can install it to your $GOPATH/bin (defaults to ~/go/bin) with "go get github.com/anisse/websocktty"
-
-I can reproduce the bug with it by simply pasting a long-enough (5 to 20 characters) string.
-
-I could not reproduce the bug with qemu's  "-serial tcp" and netcat, so this problem might indeed be limited to the websock channel implementation.
-
-The QEMU project is currently considering to move its bug tracking to
-another system. For this we need to know which bugs are still valid

-"Incomplete" now.

-qemu-system-arm and qemu-system-aarch64 QMP hangs after kernel boots
-
-After booting a Linux kernel on both arm and aarch64, the QMP sockets gets unresponsive. Initially, this was thought to be limited to "quit" commands, but it reproduced with others (such as in this
-reproducer).  This is a partial log output:
-    
-   >>> {'execute': 'qmp_capabilities'}
-   <<< {'return': {}}
-   Booting Linux on physical CPU 0x0000000000 [0x410fd034]
-   Linux version 4.18.16-300.fc29.aarch64 (<email address hidden>) (gcc version 8.2.1 20180801 (Red Hat 8.2.1-2) (GCC)) #1 SMP Sat Oct 20 23:12:22 UTC 2018
-   ...
-   Policy zone: DMA32
-   Kernel command line: printk.time=0 console=ttyAMA0
-   >>> {'execute': 'stop'}
-   <<< {'timestamp': {'seconds': 1558370331, 'microseconds': 470173}, 'event': 'STOP'}
-   <<< {'return': {}}
-   >>> {'execute': 'cont'}
-   <<< {'timestamp': {'seconds': 1558370331, 'microseconds': 470849}, 'event': 'RESUME'}
-   <<< {'return': {}}
-   >>> {'execute': 'stop'}
-    
-Sometimes it takes just the first "stop" command.  Overall, I was able to reproduce 100% of times when applied on top of 6d8e75d41c58892ccc5d4ad61c4da476684c1c83.
-
-The reproducer test can be seen/fetched at:
- - https://github.com/clebergnu/qemu/commit/c778e28c24030c4a36548b714293b319f4bf18df
-
-And test results from Travis CI can be seen at:
- - https://travis-ci.org/clebergnu/qemu/jobs/534915669
-
-For convenience purposes, here's qemu-system-aarch64 launching and hanging on the first "stop":
- - https://travis-ci.org/clebergnu/qemu/jobs/534915669#L3615
- - https://travis-ci.org/clebergnu/qemu/jobs/534915669#L3645
-
-And here's qemu-system-arm hanging the very same way:
- - https://travis-ci.org/clebergnu/qemu/jobs/534915669#L3780
- - https://travis-ci.org/clebergnu/qemu/jobs/534915669#L3800
-
-I have an update on this.  Eric and myself attempted to zero in the
-exact cause.  A few things we discovered:
-
- 1) It has nothing to do with having a kernel running
- 2) It has to do with having a chardev that is a server socket.  This
-    test produces command line arguments such as:
-
-   -chardev socket,id=console,path=<path>.sock,server,nowait \
-   -serial chardev:console
-
- 3) It doesn't seem to have a connection to the test infrastructure code
-    (python/qemu/qmp/*), as a I made a number of experiments which
-    yielded no differences in behavior.
-
-So, the reproducer given at:
-
- https://github.com/clebergnu/qemu/commit/c778e28c24030c4a36548b714293b319f4bf18df
-
-Continues to be be valid (and continues to be limited to arm and aarch64).
-Now, after a number of experiments, the following was found to be a 100%
-reproducible *workaround*:
-
- https://github.com/clebergnu/qemu/commit/e1713f3b91972ad57c089f276c54db3f3fa63423
-
-That basically shutdowns the *console* socket before proceeding with further QMP
-interaction.  The effectiveness of the workaround can be seen here:
-
- aarch64 command line:
-  - https://travis-ci.org/clebergnu/qemu/jobs/535459499#L3633
- aarch64 QMP interaction:
-  - https://travis-ci.org/clebergnu/qemu/jobs/535459499#L3663
-
- arm command line:
-  - https://travis-ci.org/clebergnu/qemu/jobs/535459499#L3747
- arm QMP interaction:
-  - https://travis-ci.org/clebergnu/qemu/jobs/535459499#L3767
-
-I hope this provides a few more hints into the real issue.
-
-
-A patch for this bug has been merged here:
-https://git.qemu.org/?p=qemu.git;a=commitdiff;h=085809670201c6d3a33e3
-... can we close this ticket now?

-SDL support missing from qemu-1:3.1+dfsg-2ubuntu3.1
-
-qemu support is missing from qemu-1:3.1+dfsg-2ubuntu3.1 on Disco. This is dispite qemu --help saying its available. SDL support is needed to use Packer(https://www.packer.io/) in graphical mode.
-
-# qemu-system-x86_64 -cpu host -smp 2,sockets=2,cores=1,threads=1 -machine type=pc,accel=kvm -display sdl -cdrom ubuntu.iso
-qemu-system-x86_64: Display 'sdl' is not available.
-
-# qemu-system-x86_64 --help | grep sdl
--display sdl[,frame=on|off][,alt_grab=on|off][,ctrl_grab=on|off]
--sdl            shorthand for -display sdl
-
-Hi Lee,
-TL;DR: there will be no sdl support anymore for newer qemu's. (make it) Use "-display gtk" instead.
-
-Details:
-#1 SDL 1.2 vs SDL 2.0 vs working fine
-1.2 was in main all the time and worked, but got unsupportable over time.
-SDL2 was tried, but failed badly in quite some experiments for Debain and 
-Ubuntu. That led to the choice of both distributions to go with the more
-modern GTK backend instead.
-Ubuntu (at Bionic staying at SDL1.2):
-- sdl2 is yet too unstable for the LTS Ubuntu release given the reports
-  we still see upstream and in Debian - furthermore sdl2 isn't in main yet,
-  so we revert related changes to stick with the proven for now:
-Debian then followed for #839695, #886671, #879536, #879534, #879532, #879193, #894852
-That also matches upstream where GTK backend for graphics is the #1 thing.
-
-#2 Supportability
-The reason everyone wanted to get off SDL was maintainability as I mentioned. And as of today you'll find that none of the SDL libs is in main anymore (since Cosmic).
-*sdl* is universe nowadays.
-And we can't make a good case for it (to MIR it) as GTK solves it - at least from the qemu POV.
-
-#3 About the man page, this isn't patched for features enabled/disabled by the upstream build system. For example it also contains "pvrdma" which is disabled for security reasons (and many other things).
-
-I must conclude that as-is I won't enable sdl, but then why does it insist on `-display sdl` in the first place. `-display gtk` is just as good or better. Is that our package of packer.io that we'd want to adapt or a PR for upstream maybe?
-
-Also misfiled against upstream's Qemu - this clearly was meant for Ubuntu's Qemu as technically upstream is still fine enabling sdl (if the package builder wants to).
-
-Changing the bug tasks ...
-
-Ha, Thomas beat me to re-target the bug while I was checking my inbox - thanks :-)
-
-Thanks for the explanation. MAAS is starting to use Packer to create custom images so we may be packaging this soon. I will filed an upstream bug[1] and created a patch[2] to fix the issue.

-Support IP_MULTICAST_IF socket option in linux-user
-Additional information:
-I've run into this limitation in qemu-aarch64-static version Debian 1:6.2+dfsg-2ubuntu6.12, but from the link above, it doesn't seem to be implemented on master yet.
-
-Here's some source code that demonstrates the failure:
-```
-#include <sys/socket.h>
-#include <arpa/inet.h>
-#include <netinet/ip.h>
-#include <unistd.h>
-#include <assert.h>
-#include <stdio.h>
-
-int main()
-{
-    int fd, ret;
-    struct in_addr addr = {htonl(INADDR_LOOPBACK)};
-
-    fd = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
-    assert(fd >= 0);
-    ret = setsockopt(fd, IPPROTO_IP, IP_MULTICAST_IF, &addr, sizeof(addr));
-    if (ret < 0)
-    {
-        perror("setsockopt failed");
-        return 1;
-    }
-    close(fd);
-    printf("Success!\n");
-    return 0;
-}
-```
-
-When run under qemu, it gives the error `setsockopt failed: Protocol not available`.
-
-It doesn't look like it should be too hard to support (certainly no worse than IP_ADD_MEMBERSHIP). Let me know if I can help with a patch.

--netdev socket uses 100% cpu on Windows host
-
-On Windows hosts, any `-netdev socket` option (tcp listen, tcp connect, udp passing a fd) causes qemu to use 100% cpu. The guest still runs, but only sluggishly.
-
-A simple testcase is:

-qemu user static binary seems to lack support for network namespace.
-
-Whenever I execute emerge in gentoo linux in qemu-aarch64 chroot, I see the following error message.
-
-Unable to configure loopback interface: Operation not supported
-
-If I disable emerge's network-sandbox which utilizes network namespace, the error disappears.
-
-Could you run qemu unimplemented error trace, by using "export QEMU_LOG=unimp"?
-
-You can also set the QEMU_STRACE="" to see which syscall fails.
-
-I executed "emerge" with QEMU_LOG=unimp and QEMU_STRACE="".

-  23473 socket(16,,IPPROTO_IP) = 5

-So you're right 16 is AF_NETLINK

-
-Could you run something like "sudo strace -yyy unshare --net chroot ..." with your failing binary to see what returns the host kernel?
-
-Can you rephrase your question? I don't know what to do with your question.
-
-I need the strace result of _configure_loopback_interface in a qemu-aarch64 chroot.
-
-But as strace cannot be started in the chroot you must strace the "chroot" command and its children.
-
-So something like "sudo strace -yyy chroot <your chroot directory> <your test path>"
-
-I just called _configure_loopback_interface in a qemu-aarch64 chroot, and the error is not reproducible with qemu-4.2.0. Has it been fixed?
-
-Yes, it's fixed in v4.2.0, and with the help of your test program I've bisect to the fix:

-    Fix unsigned integer underflow in fd-trans.c
-    
-    In any of these `*_for_each_*` functions, the last entry in the buffer (so the
-    "remaining length in the buffer" `len` is equal to the length of the
-    entry `nlmsg_len`/`nla_len`/etc) has size that is not a multiple of the
-    alignment, the aligned lengths `*_ALIGN(*_len)` will be greater than `len`.
-    Since `len` is unsigned (`size_t`), it underflows and the loop will read
-    pass the buffer.
-    
-    This may manifest as random EINVAL or EOPNOTSUPP error on IO or network
-    system calls.

-/usr/share/applications/qemu.desktop should have an "Exec=" key.
-
-According to the www.freedesktop.org .desktop-file specification, all "Application" desktop files should have an "Exec=" key. The one in qemu doesn't. 
-
-This can be easily verified by running kbuildsycoca4 if KDE4 is present, but the issue is not DE-dependent.
-
-Which binary exactly should be assigned as the default one, I don't know.
-
-The specification can be seen here:
-
-https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html#exec-variables
-
-Adding an exec field would not be right, because QEMU can't simply be launched from the desktop without any arguments. There needs to be a long string of arguments given that are different for every QEMU that is launched. The only viable way to actually launch QEMU is interactively from the terminal, or indirectly via a 3rd party app like virt-manager. We only created the qemu.desktop file in the first place because Wayland needs this to be present in order to identify what Icon to display for a window. 
-
-Note that  QEMU sets the NoDisplay=true property to tell desktops not to display this entry. I don't think KDE should be warning about missing Exec entry in this case.
-
-
-I'll report a bug in KDE and let's see if the guys agree. Maybe it is a deficiency of the .desktop specification.
-
-
-Thank you Lockywolf for this bug report.  Have you filed one against KDE as you previously mentioned?  If so, could you provide us with a link?  Thanks in advance!
-
-I am sorry I haven't dealt with this bug for quite a while. KDE 5 is not properly working on my distro, and I wanted to test it when it stabilises. 
-
-If qemu dislikes long-standing bugs, this bug can be closed, and I'll open a new one when I have time to test it on the new KDE.
-
-
-What's the actual problem we're trying to solve here? What needs to be tested?
-
-I can confirm that this behaviour is still present on kde 5.20.4.
-
-You can run e.g. khelpcenter and observe:
-
-kf.service.services: The desktop entry file "/usr/share/applications/qemu.desktop" has Type= "Application" but no Exec line
-kf.service.sycoca: Invalid Service :  "/usr/share/applications/qemu.desktop"

-default nic device created even though supplied by configfile
-
-QEMU emulator version 4.1.94
-
-Documentation states that qemu will create a default nic as long as not explicitly forbidden (-nic none) or defined ( e.g. -nic <options>).
-
-Observation:
-Even though qemu-system-ppc is started with "-readconfig" (which defines a nic), another nic gets created. When additionally suppling "-nic none", only the nic of the config file is created.
-As matter of fact, if all items that are defined in config file are supplied as command line arguments, no further nic is created. 
-
-Expectation:
-When a nic is defined in config file, the default guest-nic should not get created.
-That would match behavior when all items, defined in config file are supplied as command line arguments.
-
-
-Attached config file.

-The QEMU project is currently moving its bug tracking to another system.

-
-If the bug has already been fixed in the latest upstream version of QEMU,
-then please close this ticket as "Fix released".
-
-If it is not fixed yet and you think that this bug report here is still
-valid, then you have two options:
-
-1) If you already have an account on gitlab.com, please open a new ticket
-for this problem in our new tracker here:
-
-    https://gitlab.com/qemu-project/qemu/-/issues
-
-and then close this ticket here on Launchpad (or let it expire auto-

-
-2) If you don't have an account on gitlab.com and don't intend to get

-the state back to "New" or "Confirmed" within the next 60 days (other-
-wise it will get closed as "Expired"). We will then eventually migrate

-virtio only support packed ring size power of 2
-
-Issue discription：
-When QEMU starts with "-device virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01,disable-modern=false,mrg_rxbuf=on,rx_queue_size=1025,tx_queue_size=1025,mq=on,vectors=15,packed=on"
-
-It raises error: Invalid rx_queue_size (= 1025), must be a power of 2 between 256 and 1024
-
-Analysis:
-According to virtio1.1 spec, the packed queue size value does not have to be a power of 2.
-
-Maybe the virtio need to be revised?

-Legacy IGD passthrough in QEMU 5 disabled
-
-Bug with tag v5.0.0, or commit fdd76fecdde1ad444ff4deb7f1c4f7e4a1ef97d6
-
-As of QEMU 5 Legacy IGD PT is no longer working.
-
-Host is a Xeon E3-1226 v3 and my method to test is to run the following:
-
-./qemu-system-x86_64 \
-  -device 'pci-bridge,id=pci.1,chassis_nr=1,bus=pci.0,addr=0x1f' \
-  -device 'vfio-pci,host=00:02.0,addr=02.0' \
-  -L '/usr/share/kvm' \
-  -nographic \
-  -vga none \
-  -nodefaults
-
-in the hope of seeing a "IGD device 0000:00:02.0 cannot support legacy mode due to existing devices at address 1f.0" error.
-
-The culprit appears to be this commit:
-
-https://github.com/qemu/qemu/commit/29d62771c81d8fd244a67c14a1d968c268d3fb19
-
-Specifically the following block in pci-quirks.c:
-
-#ifdef CONFIG_VFIO_IGD
-    vfio_probe_igd_bar4_quirk(vdev, nr);
-#endif
-
-as the kconfig variable CONFIG_VFIO_IGD doesn't appear to be available outside of makefiles as described here: https://qemu.weilnetz.de/doc/devel/kconfig.html. I can confirm that the igd code is being pulled in as removing this check, as would defining the variable I presume, makes Legacy IGD PT work again (ie I see the expected "existing devices" error).
-
-I first spotted this in Proxmox, but have confirmed the bug by building QEMU sources.
-
-Hi! That info in kconfig.html is not up to date anymore, we are generating now #defines for the Kconfig switches. And in my build tree, I can see:
-
-$ grep CONFIG_VFIO_IGD *-softmmu/*.h
-x86_64-softmmu/config-devices.h:#define CONFIG_VFIO_IGD 1
-
-... what's missing in that file is simply a "#include "config-devices.h" ... sorry, that fell somehow through the cracks. I'll prepare a patch for that.
-
-Looks similar to https://bugs.launchpad.net/qemu/+bug/1879175
-
-Looks the same, although the title was misleading so I missed it.

-Forward host UNIX socket to guest TCP port
-
-Hello. I've been racking my brain trying to work out if this is possible.
-
-I would like to be able to forward to a guest TCP port, via a host UNIX socket to avoid opening a TCP port on the host. For example:
-
-qemu-system-i386 [...] -nic user,hostfwd=unix:/path/to/socket-:22
-
-and then connect to the VM like:
-
-ssh -o "ProxyCommand socat - unix-connect:/path/to/socket" user@0.0.0.0
-
-QEMU, as versatile as it is, doesn't appreciate my intuited syntax "hostfwd=unix:...". It is also unhappy with:
-
-qemu-system-i386 [...] \
-    -chardev socket,id=foo,path=/path/to/socket,server,nowait \
-    -nic user,hostfwd=chardev:foo-:22
-
-And:
-
-qemu-system-i386 [...] \
-    -nic user \
-    -chardev socket,id=foo,path=/path/to/socket,server,nowait \
-    -chardev socket,id=foo,host=10.0.2.15,port=22
-
-I already found out how to connect in the opposite direction, **from** guest TCP to host UNIX, via guestfwd -> cmd -> socat. So I feel like there ought to be a way.
-
-If this is not yet a feature I would like to request it, and if it is, please tell me how!

-Most of the time it will outright segfault within a few seconds, seemingly when the prometheus server polls for data.
-
-But, about once every 10 times, it will not sefault and will continue working just fine forever.
-
-The dynamically linked version of qemu (built without --static) always works without segfaulting, but it just doesn't work, the prometheus server gets no data from it. Again, once in a while it will work, but even when it doesn't work it won't segfault.
-
-This vaguely feels like a memory alignment issue somewhere, but my debug-fu is not quite strong enough to attack the problem.
-
-As another interesting data point - with dynamically linked qemu-x86_64, when it doesn't work, the process is consuming about 140% of CPU. On a successful run, the process is consuming about 30% of CPU.

-Instability in IVSHMEM after updating QEMU 4.2 -> 5.0
-
-Updating Ubuntu from 20.08 to 20.10 which updates QEMU from 4.2 to 5.0 results in the virtual machines freezing when the IVSHMEM interface is active.  This workstation typically runs several windows 10 virtual machines that are accessed locally:  two using the spice viewer and one that uses an passthrough assigned GPU accessed through a viewer called Looking Glass.  Looking Glass uses the IVSHMEM device interface to pass captured frames from the windows virtual machine to the linux host for display by a viewer application.
-
-This workstation was 100% stable under Ubuntu 20.08 (QEMU 4.2).  It handled a variety of heavy loads all day it never froze or crashed.  It became unstable under Ubuntu 20.10 (QEMU 5.0), seemingly triggered by high levels of SHM activity.  I was able to reliably reproduce the problem when playing a video in the looking-glass vm while playing another video in a spice vm.  Other scenarios would also trigger this problem less reliably, but this video playback scenario would trigger it after 3-5 minutes of playback.
-
-The result of this new instability would manifest itself by all running vms on the host freezing but the host was not visibly effected.  I could find no warnings or errors in any relevant system or QEMU logs.  It wasn't just spice, when I accessed the gpu-passthru vm via directly assigned devices it was frozen, still outputting video of the last frame before the crash.  All vms would have to be force-shutdown and the host rebooted to regain vm functionality.  Just forcing shutdown and restarting a vm would result in showing 'running' status but it would be frozen and inaccessible until system reboot.
-
-I suspect this is a QEMU host / kernel error for several reasons:  Having to reboot the host, insensitivity to VM changes including virtio-win version, etc.  I suspect it's related to IVSHMEM due to the correlation of the freeze to the looking-glass related activity.
-
-This might be kernel / PCIe / power management related in some way.  While experimenting to troubleshoot this issue I was able to trigger the error more quickly by disabling PCIe power management in the BIOS.
-
-The system was 100% stable under QEMU 5.0 when not running the looking-glass vm, quite stable when the looking-glass vm was idle or lightly used, but appeared increasingly unstable as SHM activity increased.
-
-Sorry if this is a bit anecdotal, this is my work machine and unfortunately today I was forced to rollback restore to Ubuntu 20.08 (QEMU 4.2) from backup so I can work on Monday.  The system returned to 100% stability after returning to 20.08.
-
-If requested I can restore the Ubuntu 20.10 snapshot to reproduce & gather information as directed.
-
-Can you reproduce this with the latest upstream QEMU release (v5.1)? Or did you only try with the versions that ship with Ubuntu?
-
-This problem occurred with the QEMU 5.0 version that was distributed with the Ubuntu 20.10 update.
-
-
-
-Ok, so I'm moving this to the Ubuntu bug tracker.
-
-Hi Dave,
-there is no Ubuntu 20.08 I'd know of I assume you mean 20.04 (Focal Fossa) as that would have qemu 4.2. 
-We'd need to start sorting out if this is a kernel or qemu issue.
-Since you are know rolled back to 20.04 you might give [1] a try that just bumps the core virt components but keeps everything else on 20.04.
-
-Report back if that triggers the issue on Focal. If it does you can then go back to the packages of 21.04 one by one e.g. bios first, then libvirt, ... until we can pinpoint if it indeed is qemu or another package.
-If instead it works with these builds then that implies we need to look at the kernel, in that case still speak up here please.

- Hi Christian,
-Thanks of your interest. Yes, meant to say Ubuntu 20.04.1 LTS.
-This weekend if I have the time I'm going to install 20.10 on a separate partition and experiment on that.
-Would you happen to know if anyone else is reporting similar problems?
-If I find anything interesting I'll report back on this email thread.

-chardev zombie TCP session
-Description of problem:
-When user terminates TCP session ungracefully (eg: power-cycle or network cable disconnect), the TCP session keeps in established status forever. In this state, new sessions can't access the chardev, since the zombie TCP session keeps exclusive access to chardev.
-Steps to reproduce:
-1.Establish client session to chardev TCP socket.  
-2.Power-off the client machine.  
-3.Establish a new client session  
-4.Observe that old TCP session is never killed and new session can connect but not interact with chardev.
-Additional information:
-Suggestions to resolve this and improve the chardev feature:
-- enable TCP keep-alive for chardev server.
-- allow multiple client sessions concurrently, where chardev output is broadcasted to all client sessions, and chardev input is shared by all clients.

-UNIX socket path is too long
-Description of problem:
-At [Unikraft](https://unikraft.org) we facilitate the construction and also runtime lifecycle management of ultra-lightweight virtual machine unikernels.  We have developed [`kraft`](https://github.com/unikraft/kraftkit), an open-source tool which facilitates this across a number of different virtual machine monitors, [including QEMU](https://github.com/unikraft/kraftkit/tree/staging/machine/qemu).
-
-We are receiving increased reports of the following error from our users:
-
-```
-could not start and wait for QEMU process: qemu-system-x86_64: -qmp unix:/Users/__USERNAME__/.local/share/kraftkit/runtime/37a7691a-d402-4760-b493-692bb8d0460a/qemu_control.sock,server,nowait: UNIX socket path '/Users/__USERNAME__/.local/share/kraftkit/runtime/37a7691a-d402-4760-b493-692bb8d0460a/qemu_control.sock' is too long
-```
-
-We systematically build the relevant QEMU process command line and arguments with flags [via our Go SDK](https://github.com/unikraft/kraftkit/blob/staging/machine/qemu/v1alpha1.go#L180-L229) and include what has become an erroneously long UNIX path for the QAPI control socket which we use to manage instantiated VM instances.
-
-This issue tracks the increasing of maximum path length for the `-qmp` (and maybe other) flags which accept paths.
-Steps to reproduce:
-1. Install [`kraft`](https://github.com/unikraft/kraftkit), [Unikraft](https://unikraft.org)'s companion command-line client;
-2. Update KraftKit's config file to include an arbitrarily long path for `runtime_dir` by editing `~/.config/kraftkit/config.yaml`;
-3. Start a QEMU unikernel instance with `kraft run --arch x86_64 --plat qemu unikraft.org/helloworld:latest`

-IVSHMEM device doesn't work for sharing memory with virtiofsd
-Description of problem:
-Trying to share a folder on the host to the guest with `virtiofsd` using the `ivshmem-plain` device doesn't work (for memory sharing), while using a NUMA node (with `-numa node,memdev=mem`) works just fine.
-Steps to reproduce:
-1. Install `virtiofsd`
-2. Run `/usr/libexec/virtiofsd --socket-path=/tmp/vhostqemu --shared-dir=$HOME --cache always` as a regular user (or with another shared directory, it doesn't matter)
-3. Run QEMU with the aforementioned command line as a regular user
-4. Wait a bit for the OS to load and `virtiofsd` should error out
-Additional information:

-nbd URI wrong export name (regression in qemu 9.1)
-Description of problem:
-qemu with an nbd URI seems to pass the wrong export name to the server, if the exportname is `.`.  This seems
-to be a regression in qemu 9.1, because it didn't happen in 9.0.
-Steps to reproduce:
-```
-$ nbdkit -fv -U - null --run 'qemu-img info "nbd+unix:///.?socket=$unixsocket"'
-...
-nbdkit: null[1]: debug: null: open readonly=0 exportname="" tls=0
-```
-
-In qemu 9.0 this was correct:
-
-```
-nbdkit: null[1]: debug: null: open readonly=0 exportname="." tls=0
-```

-Description of problem:
-When using hostfwd, only IPv4 connections are forwarded.
-Steps to reproduce:
-1. Start vm with the aforementioned command using a system image that comes with a socket listening on both IPv4 and IPv6. (I used Arch Linux Box which comes with `sshd` enabled by default).
-2. Connect to the forwarded socket:
-  - IPv4 succeeds:
-    - `ssh -oPasswordAuthentication=yes arch@127.0.0.1 -p 52022`
-    - `nc -zv 127.0.0.1 52022`

-    - `ssh -oPasswordAuthentication=yes arch@::1 -p 52022`
-    - `nc -zv ::1 52022`

-qemu spinning on serial port writes
-
-As originally found at http://<email address hidden>/msg08745.html from 3 years ago! 
-
-Basically qemu seizes up in the event that the file descriptor for its emulated serial port has a full buffer, i.e. write() returns EAGAIN.  For me, this happened when the serial port was being directed through a UNIX socket, with a default-sized 4KB buffer.  Just the normal output from a Linux kernel boot caused it to seize up, and stop the main emulation / select loop.
-
-My suggestion is to remove the detection of EAGAIN in qemu-char.c:521, so that if the buffer is full, KVM discards the byte(s) it was trying to write.  This is a surely better outcome than the process spinning forever.
-
-I will submit a separate patch to control the buffer sizes when creating UNIX sockets, which will help allow slow-reading processes to tune things so that they don't miss any output.
-
-Additionally, in the context of a hosted environment, if the -serial option is used, this could be a small security issue. An untrusted user of a guest system, knowing their serial output is going via a small buffer, could spew output to their /dev/ttyS0 at a rate fast enough to trigger this bug and eat a CPU core on the host.
-
-To quote David S. Ahern's original bug report (mine was the same, only with the latest version from git, so line numbers may have changed - my suggested fix above is accurate though):
-
-I am trying to redirect a guest's boot output through the host's serial
-port.  Shortly after launching qemu, the main thread is spinning on:
-
-write(9, "0", 1)   = -1 EAGAIN (Resource temporarily unavailable)
-
-fd 9 is the serial port, ttyS0.
-
-
-The backtrace for the thread is:

-
-send_all() invokes unix_write() which by design is not breaking out on
-EAGAIN.
-
-The following command is enough to show the problem:
-
-qemu-system-x86_64 -m 256 -smp 1 -no-kvm \
-    -drivefile=/dev/cciss/c0d0,if=scsi,cache=off,boot=on \
-    -vnc :1 -serial /dev/ttyS0
-
-
-The guest is running RHEL3 with the parameter 'console=ttyS0' added to
-grub.conf; the problem appears to be with qemu, so I would expect it to
-show with any linux guest. This particular host is running RHEL5.2 with
-kvm-81, but I have also seen the problem with Fedora-9 as the host OS.
-
-Yes, the serial port of the server is connected to another system via a
-null modem. If I change the serial argument to '-serial udp::4555' and
-use  'nc -u -l  localhost 4555  > /dev/ttyS0' I see the guest's boot
-output show up on the second system as expected. I'd prefer to be able
-to use the serial port connection directly without nc as a proxy.
-Suggestions?
-
-I have a similar problem, and the problem goes away if I remove the "-serial pty" device from my command line:
-
-/home/mrhines/qemu/x86_64-softmmu/qemu-system-x86_64 /kvm_repo/cb/vmbase -serial pty
-
-Such a simple command line, but QEMU seizes up and slows to a crawl and the host CPU is spinning at 100%
-
-Which version of QEMU have you been using here? Can you still reproduce this problem with the latest version of QEMU (currently version 2.9)?
-
-I'm confident this has been solved a while ago. When this bug was reported, the code was indeed broken wrt EAGAIN handling. 
-
-The chardev code has long since been re-written though, and the send_all method replaced by io_channel_send_all() which will handle EAGAIN by returning instead of spinning in a loop.
-
-Specifically this commit changed the code to stop spinning in send_all() on EAGAIN

-Thank you for the report. Currently QEMU devices only provide access
-methods up to 32 bits, a 64 bit access is emulated with two 32 bit
-accesses. So it is not possible to handle a 32 bit access differently
-from a 64 bit one for now.
-
-So far this hasn't been considered to be a problem for x86, though it
-is clearly not correct for Sparc and Alpha. This report shows that it
-is necessary to add 64 bit access methods (or otherwise handle 64 bit
-accesses more realistically) since x86 is also affected.
-
-Adding the 64 bit method would be a major refactoring though and there
-are other designs possible.
-
-
-Triaging old bug tickets ... can you somehow still reproduce this problem with the latest version of QEMU (currently v2.9), or could we close this ticket nowadays?

-linux-user: sendmsg fails to send messages without iov
-Description of problem:
-When run via qemu `sendmsg` fails to send messages which contain a zero length `iov` but _do_ contain ancillary data. This works fine on plain Linux.
-
-A practical example: the `ell` library relies on this for setting the IV on a kernel crypto (`AF_ALG`) socket: https://git.kernel.org/pub/scm/libs/ell/ell.git/tree/ell/cipher.c#n526
-
-A message without data but only ancillary data is used to set the IV.
-Steps to reproduce:
-See [qemu_ancillary.c](/uploads/84ee20aa3b9178022847d6cd7fcf0048/qemu_ancillary.c) for a self contained testcase which sends two mesages (one with `msg_iovlen=0`, one with `msg_iovlen=1`).
-
-(Test case is to be considered GPL, as I've copied bits from `ell`)
-
-Native:
-```
-$ strace -esendmsg ./a.out 
-sendmsg(6, {msg_name=NULL, msg_namelen=0, msg_iov=NULL, msg_iovlen=0, msg_control=[{cmsg_len=36, cmsg_level=SOL_ALG, cmsg_type=0x2}], msg_controllen=40, msg_flags=0}, 0) = 0
-sendmsg(6, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=16}], msg_iovlen=1, msg_control=[{cmsg_len=36, cmsg_level=SOL_ALG, cmsg_type=0x2}], msg_controllen=40, msg_flags=0}, 0) = 16
-+++ exited with 0 +++
-```
-
-
-Qemu (observe missing sendmsg call):
-```
-$ strace -esendmsg ~/debug/qemu/build/qemu-x86_64 ./a.out 
-sendmsg(6, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=16}], msg_iovlen=1, msg_control=[{cmsg_len=36, cmsg_level=SOL_ALG, cmsg_type=0x2}], msg_controllen=40, msg_flags=0}, 0) = 16
-+++ exited with 0 +++
-```
-
-For a practical reproducer:
-
-1. Compile and run `ell`'s `test-cipher` test case:
-
-```
-$ ~/debug/qemu/build/qemu-x86_64 ./unit/test-cipher 
-TEST: unsupported
-TEST: aes
-TEST: aes_ctr
-test-cipher: unit/test-cipher.c:102: test_aes_ctr: Assertion `!r' failed.
-Aborted (core dumped)
-```
-
-A strace will look similar.
