the translation cached for a whole page of instructions; if this function is unable to translate a whole page, it's supposed to simply return `-1`, and then the caller is supposed to translate and execute on a per-instruction basis. In this case `get_page_addr_code_hostp` calls `tlb_fill`, which then calls `riscv_cpu_tlb_fill`, which then calls `get_physical_address_pmp` to perform the PMP access checks. When said instructions are covered by a PMP region which is smaller than a page, this check then fails, since PMP regions must cover the whole access in order to allow it. At this point `riscv_cpu_tlb_fill` will see that a PMP fault happened, and since `probe` is set to false by `get_page_addr_code_hostp`, it will throw a RISC-V access fault exception instead of just returning a failure that `get_page_addr_code_hostp` can handle (by only accessing the memory of the specific instruction instead, which will be fully covered by the PMP region). + +I haven't tried to fix it myself (my first idea is to simply make `get_page_addr_code_hostp` set the probe flag), since I'm not sure if changing that part of TCG will affect other architectures that I'm not aware of. diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1056 b/results/classifier/mode-deepseek-r1:32b/output/system/1056 new file mode 100644 index 000000000..4d3b7dd35 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1056 @@ -0,0 +1,3 @@ + + +Bad Performance of Windows 11 ARM64 VM on Windows 11 Qemu 7.0 Host System diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1057 b/results/classifier/mode-deepseek-r1:32b/output/system/1057 new file mode 100644 index 000000000..ade1a3fbb --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1057 @@ -0,0 +1,25 @@ + + +AArch64: ISV is set to 1 in ESR_EL2 when taking a data abort with post-indexed instructions +Description of problem: +I think that I have a Qemu bug in my hands, but, I could still be missing something.

All I know is putting this back the way it was makes SunOS happy again. Unfortunately it may also break something else, so somebody more knowledgeable than I should investigate further. + +If you're worried that reproducing this will be difficult, don't be. I prepared detailed instructions, scripts and all the images you should need to create a virtual SunOS disk and install the OS on it. This includes the OpenProm images and installation ISO. + +You can find everything here (consult readme.txt for details): + +http://people.freebsd.org/~wpaul/sunos-qemu + +The quick install option is very simple. Once you finish writing the OS to the disk and try to boot off it the first time, you should encounter the error above. + +But wait, there's more. + +SunOS 4 has this quirk where it only works with CD-ROM drives that report a block size of 512 bytes, instead of the default of 2048. Now, I realize that just recently, there was a change committed that allows the guest to change the block size with the MODE SELECT command. However this doesn't seem to be good enough for SunOS (I tried it, it still hates the drive). Note that scsi-disk.c hard codes the block size for CD-ROMs to 2058 in scsi_cd_realize(). What would be really nice is if was possible to override this from the command line, and that addresses the problem quite nicely. + +At the same URL above, I also provided a small patch to scsi-disk.c which implements this feature. This allows the user to set the initial block size with logical_block_size=512 when specifying the device parameters. The qemu_sparc5.sh and qemu_sparc20.sh scripts show an example of this. + +One more thing: I wanted to simulate a SPARCstation 20, but I found that SunOS 4 would panic when I tried to boot it with this configuration, even if I used the correct SS20 OpenProm image. The problem here has to do with the SUNW,DBRIe device. QEMU doesn't simulate this device, but it creates dummy resources for it, including a PROM space. The problem is that this space is empty. This causes the OpenProm to create a node with an empty "name" property, which is a condition the SunOS kernel doesn't expect. The result is that the kernel tries to dereference a NULL pointer and panics. (The OpenProm code itself seems to let it slide.) + +To work around this, I patched the sun4m.c code to create the SUNW,DBRIe device such that its PROM space can actually be populated with an FCode image, and I created a simple one with a valid name property so that the kernel doesn't panic. SunOS complains later that it can't find the audio device because it's not actually implemented, but at least it doesn't crash. + +I don't know how this would actually be addressed in QEMU proper since the existing FCode images that QEMU uses come from OpenBios. + +Finally, one thing I haven't figured out is that using the -smp flag with SunOS 4 never seems to work. The OpenProms and the SunOS kernel only ever seem to detect one CPU. I am not that broken up about this though, because SunOS 4 never really did SMP very well to begin with. +Steps to reproduce: +Download all the files at: + +http://people.freebsd.org/~wpaul/sunos-qemu + +You can download just: + +http://people.freebsd.org/~wpaul/sunos-qemu/sunos-qemu.tar.gz + +if you want everything in one shot. + +Read the readme.txt file. This will walk you through trying to create a bootable SunOS system. You should apply the CD-ROM patch to scsi-disk.c and use the qemu_sparc5.sh script initially. This should allow you to install the miniroot from the CD image onto the virtual hard drive, but it will fail booting due to the esp controller problem. The qemu_sparc20.sh script will only boot successfully if you apply the sun4m.c patch and copy QEMU,dbri.bin to the QEMU firmware directory. +Additional information: +I'm not planning to provide a pull request for any of this. As I said, I'm not sure if my fixes are necessarily correct (especially the esp.c one). I'm satisfied that they work for me, but I want to leave it to the appropriate maintainers do decide how to best deal with these things. + +I would be happy to answer questions and test candidate fixes though. diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1130 b/results/classifier/mode-deepseek-r1:32b/output/system/1130 new file mode 100644 index 000000000..f6d923c2a --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1130 @@ -0,0 +1,31 @@ + + +error on run qemu-system-aarch64 -icount shift=1,align=off,sleep=on -smp 2 +Description of problem: +This issue happen with the most recent version. +* Compile parameters: +``` +./configure --target-list=aarch64-softmmu --prefix=pwd/release --disable-werror --enable-lto --enable-capstone --enable-system --enable-fdt --disable-xen --disable-kvm --enable-plugins +``` +* run： +``` +qemu-system-aarch64 -nographic -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 2 -vnc :2 -m 4080 -kernel /home/yuzy/mywork/linux/linux-5.15.30/arch/arm64/boot/Image.gz -initrd /home/yuzy/mywork/build/rootfs.cpio.gz +``` +* error occurred： +``` +** +ERROR:../accel/tcg/tcg-accel-ops.c:79:tcg_handle_interrupt: assertion failed: (qemu_mutex_iothread_locked()) +Aborted (core dumped) +``` +Steps to reproduce: +1. run qemu-system-aarch64 -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 2 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz +2. it will assertion failed: (qemu_mutex_iothread_locked()) +Additional information: +The following two situations are good： +``` +qemu-system-aarch64 -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 1 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz +``` +``` +qemu-system-aarch64 -machine virt -cpu cortex-a57 -smp 2 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz +``` +I assume the issues are: gic diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1131 b/results/classifier/mode-deepseek-r1:32b/output/system/1131 new file mode 100644 index 000000000..b774b7e95 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1131 @@ -0,0 +1,22 @@ + + +Multiboot: could not move values from provided mmap to another address directly. +Description of problem: +When using `-kernel` to load a Multiboot file which requires a memory map(MULTIBOOT_MEMORY_INFO flag) and trying to move the values in the provided mmap entries to another address directly, QEMU reboots. +```c +xxx = mmap->addr; +``` + +When moving with volatile, everything works well: +```c +volatile unsigned long long addr = mmap->addr; +xxx = addr; +``` +Steps to reproduce: +1.

It appears that the main cause of the incorrect `sin()` and `cos()` functions is due to the quotient byte being set incorrectly by `fremx`, causing MacOS to jump to the wrong segment of the lookup table for certain angle ranges. diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1316 b/results/classifier/mode-deepseek-r1:32b/output/system/1316 new file mode 100644 index 000000000..9c878efca --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1316 @@ -0,0 +1,3 @@ + + +qemu.qmp.protocol.ConnectError: Failed to establish connection: AF_UNIX path too long (on Darwin) diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1319 b/results/classifier/mode-deepseek-r1:32b/output/system/1319 new file mode 100644 index 000000000..303f9fcbe --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1319 @@ -0,0 +1,15 @@ + + +Build warnings when building qemu with 'disable-tcg' for ppc64-softmmu target +Description of problem: +Building recent upstream qemu (HEAD 2c8311241d) for 'ppc64-softmmu' target is failing due to following build warnings: + +<snip> + ../target/ppc/cpu_init.c:7018:13: error: 'ppc_restore_state_to_opc' defined but not used [-Werror=unused-function] + 7018 | static void ppc_restore_state_to_opc(CPUState *cs, +<snip> +Steps to reproduce: +1. $ git clone --recurse-submodules https://gitlab.com/qemu-project/qemu.git +2. ./configure --target-list=ppc64-softmmu --disable-tcg && make +Additional information: +Patch for this issue has been posted and reviewed at https://lore.kernel.org/all/20221116131743.658708-1-vaibhav@linux.ibm.com/ diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/132 b/results/classifier/mode-deepseek-r1:32b/output/system/132 new file mode 100644 index 000000000..b6ce9ac88 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/132 @@ -0,0 +1,3 @@ + + +AVX instruction VMOVDQU implementation error for YMM registers diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1321 b/results/classifier/mode-deepseek-r1:32b/output/system/1321 new file mode 100644 index 000000000..37520367c --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1321 @@ -0,0 +1,10 @@ + + +qemu-system-i386 runs slow after upgrading legacy project from qemu 2.9.0 to 7.1.0 +Description of problem: +Using several custom serial and irq devices including timers. +The same code (after some customisation in order to compile with new 7.1.0 API and meson build system runs about 50% slower. +We had to remove "-icount 4" switch which worked fine with 2.9.0 just to get to this point. +Even running with multi-threaded tcg did not help. +We don't use the new ptimer API but rather the old QEMUTimer. +Any suggestions to why we encounter this vast performance degradation? diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1324 b/results/classifier/mode-deepseek-r1:32b/output/system/1324 new file mode 100644 index 000000000..91a0570d6 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1324 @@ -0,0 +1,42 @@ + + +Unhandled exception when booting UEFI x86_64 system image +Description of problem: +I have a bootable Ubuntu 20.04-based operating system image that I typically flash to the internal storage of an embedded Intel Atom computer.

When an exception is raised where an index to an IDT descriptor entry needs to be encoded in an error code's selector index field it appears that QEMU's software emulation improperly encodes the IDT descriptor index as if each entry is 8 bytes rather than 16. The effect is that the descriptor index is encoded with a value that is double what it should be. + +As an example if I have a *Segment Not Present* (#NP) exception handler (which has a selector error code pushed on the stack) that is raised when I try to generate a software interrupt 0x97 that is marked not present in its IDT descriptor entry - I expect that QEMU would properly encode the value 0x97 in the Selector Index of the Selector Error Code pushed on the stack. Instead, the value stored is actually 0x12E. 0x12E is double the expected value 0x97. + +You can observe this errant value in the output of QEMU when using the `-d int` option.

Because 0x97 was marked not present exception 0x0b (Not Present) was raised as you can see in the second line. The problem is that `e=0972` is a Selector Error Code where *Bits 3..16* contain the value 0x12E instead of 0x97. **It isn't just the display value in QEMU's debug output that is wrong**, as the **Selector Error Code pushed on the interrupt stack is the same erroneous value**. + +This issue doesn't occur if you run QEMU with the `-enable-kvm` option; in BOCHS; or on real hardware.

The way GCC implements it is by turning the second part into a separate function, which the first part calls - see disassembly below. (GCC then re-uses the second part in other similar TCG helpers) + +Because we now called the second part before calling `GETPC`, we have a new return address, and `GETPC` returns the address of the first part, instead of the TCG host PC. + +``` +000000000022c870 <helper_divs32>: + 22c870: 48 83 ec 08 sub rsp,0x8 + 22c874: 85 d2 test edx,edx + 22c876: 74 22 je 22c89a <helper_divs32+0x2a> + 22c878: 48 89 f0 mov rax,rsi + 22c87b: 48 63 ca movsxd rcx,edx + 22c87e: 48 99 cqo + 22c880: 48 f7 f9 idiv rcx + 22c883: 4c 63 c0 movsxd r8,eax + 22c886: 48 89 97 10 03 00 00 mov QWORD PTR [rdi+0x310],rdx + 22c88d: 49 39 c0 cmp r8,rax + 22c890: 75 17 jne 22c8a9 <helper_divs32+0x39> + 22c892: 4c 89 c0 mov rax,r8 + 22c895: 48 83 c4 08 add rsp,0x8 + 22c899: c3 ret + 22c89a: 48 8b 54 24 08 mov rdx,QWORD PTR [rsp+0x8] + 22c89f: be 09 00 00 00 mov esi,0x9 + 22c8a4: e8 47 e5 ff ff call 22adf0 <tcg_s390_program_interrupt> + 22c8a9: e8 b2 fe ff ff call 22c760 <helper_divs32.part.0> + +000000000022c760 <helper_divs32.part.0>: + 22c760: 48 83 ec 08 sub rsp,0x8 + 22c764: be 09 00 00 00 mov esi,0x9 + 22c769: 48 8b 54 24 08 mov rdx,QWORD PTR [rsp+0x8] + 22c76e: e8 7d e6 ff ff call 22adf0 <tcg_s390_program_interrupt> +``` diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1455 b/results/classifier/mode-deepseek-r1:32b/output/system/1455 new file mode 100644 index 000000000..4d52ef628 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1455 @@ -0,0 +1,5 @@ + + +copy-paste not working +Description of problem: +copy-paste not working under Sway (wayland - wlroots) when I use `-display gtk`.

of this commit that you authored: 7e0d9973ea665bf459b2dbd173d0e51bc6ca5216, which modified the behavior of `get_page_addr_code_hostp` probes to probe a single byte, instead of a full page size (signaled by passing 0). +This means that we initially probe the first byte of the page, see that no PMP faults are raised, and then assume that no other bytes in the page can cause a PMP fault. +

Perhaps because I am the only one developing on MacOS. Maybe it's because I'm running an older intel mac.~. I managed to reproduce this on a Asus vivobook running linux +- The redox OS [reads the HPET](https://gitlab.redox-os.org/redox-os/kernel/-/blob/master/src/arch/x86_64/time.rs#L11) at addresses `0xf4`, `0x108`, `0x00` in that order. If I change the order to `0x00`, `0xf4`, `0x108`, the problem goes away. +- Even if I work around the problem by changing the order of the reads, the OS still randomly crashes. This could be related, but I can only speculate on that right now. +- Increasing qemu debug logging tends to push the problem to the 4vs8 size problem instead of the incorrect address one. The more logging, the more difficult it is to reproduce. +- I tried to bisect the issue and found I could only reproduce it after qemu version 5.2. However, the mac build broke during this process so I could not find the causal commit. Between 5.1 and 5.2 the performance is greatly increased though and I suspect whatever changed there caused the issue. +- I can't reproduce the problem with -smp 1 +- I have seen qemu segfault occasionally, but I didn't look further into it and I don't know if it's related to this issue. +- I have attempted to rule out a bug in redox. I am fairly certain nothing strange is going on there, but I can't say for sure. +- When I trigger the incorrect address bug, I mostly get a base address of `0xfec00000` which is the IO APIC. However, I do occasionally see other addresses too +- `info tlb` at the time of the fault shows + ``` + ffff8000fd3e6000: 00000000fd3e6000 X--DA---W + ffff8000fd3e7000: 00000000fd3e7000 X--DA---W + ffff8000fed00000: 00000000fed00000 X--DAC--W + ffff8000fee00000: 00000000fee00000 X--DA---W + fffffd8000000000: 0000000001e32000 XG-DA---W + fffffd8000001000: 0000000001e36000 XG-DA---W + ``` diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1573 b/results/classifier/mode-deepseek-r1:32b/output/system/1573 new file mode 100644 index 000000000..635771545 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1573 @@ -0,0 +1,3 @@ + + +TCP Previous segment not captured diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1574246 b/results/classifier/mode-deepseek-r1:32b/output/system/1574246 new file mode 100644 index 000000000..0ca4b0f59 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/system/1574246 @@ -0,0 +1,23 @@ + + +Drunken keyboard in go32v2 programs + +QEMU 2.5.0, SeaBIOS 1.9.1; I've been noticing this bug for quite a while, though. + +Steps to reproduce: + +# Create a VM image, install DOS in it (doesn't matter which) and launch it. +# Launch a "bare DOS" DPMI host (not an operating system) in it; I tested with CWSDPMI and HDPMI32. +# Run a go32v2 program which reads keyboard input (say, the Lua interpreter: <http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.1/repos/devel/lua.zip>; the Free Pascal IDE will also do; on the other hand, DOS/4GW programs seem unaffected). +# Quickly type in something random (e.g. alternate between hitting "p" and "q"), then optionally move the cursor left and right. +# Observe how some keystrokes are missed, and some are caught twice. + +The issue does NOT arise: +* on bare metal DOS, +* in VirtualBox, +* in Bochs with stock Plex86 BIOS, +* in Bochs with SeaBIOS, +* in DOSEMU, +* in DOSBox, +* in QEMU when the DPMI host is Windows 3.11/9x +so at this point I'm reasonably sure that it's the fault of either QEMU or SeaBIOS, and probably the former.

See the issue. +Additional information: +It is possible to then switch to tty2 (View->compatmonitor0, `sendkey ctrl-alt-f2`), log in as `root:chimera` or `anon:chimera` as the console prompt instructs, and type in `dmesg` (as `root`) or `doas dmesg` (as `anon`) and see that the `dmesg` contains a number of general protection faults, like this: + + + +The system used to work, but I am not sure which is the last version of QEMU where this worked, I believe 7.x. In 8.0.3 (likewise running in a Chimera environment, but it was also tested on Alpine, and I had somebody on Arch Linux test it with 8.0.2 just to rule out possible issues caused by a musl-based host environment) it crashes. It only appears to affect the `x86_64` guest architecture, as the other-architecture ISOs have graphical environment come up fine after some minutes (e.g. `ppc64le` with `qemu-system-ppc64 -M pseries-2.11,cap-htm=off -m 2048 -boot d -cdrom chimera-linux-ppc64le-LIVE-20230611-gnome.iso` works just fine). It also appears to only affect TCG emulation, as KVM likewise works fine (same command line, just `-enable-kvm` added). + +Apologies for a large testcase, but it seems to need specific graphical-adjacent services to reproduce. It should be consistently reproducible though. diff --git a/results/classifier/mode-deepseek-r1:32b/output/system/1804323 b/results/classifier/mode-deepseek-r1:32b/output/system/1804323 new file mode

(SRST): Writing a 1 causes the corresponding stream to be reset. [...] After the stream hardware has completed sequencing into the reset state, it will report a 1 in this bit. Software must read a 1 from this bit to verify that the stream is in reset.

My rough guess as to what's happening: + +1. We're not setting the MSTATUS_VS flag on initialization of the CPU, nor are we setting the mstatus_vs state to INITIALIZED. Without this, when a new thread is spawned for a vCPU, it's incorrectly determining that it can't handle vector instructions. +2. It's working sometimes because in some of the 'write_*' calls in `riscv/csr.c`, we flip the MSTATUS_VS flag on, so if one of those calls occurs first, all subsequent vector operations work too. (To be honest, I'm not quite following why we make the decision to set MSTATUS in these calls, shouldn't this be configured at CPU initialization?) +Steps to reproduce: +Please forgive the poor reproduction case, I'm still trying to wrap my head around what's going on, so haven't been able to harden a smaller example yet that would reproduce. In theory, tip-of-tree QEMU + a stock Linux system with a program that triggers a call to QEMU's vlenb instruction ahead of all other vector instructions would be the ideal case, but I'm still figuring out how to go about doing that. + +My current reproduction case is as follows: + +1. Introduce a small hack in `target/riscv/csr.c`'s `vs` function - add an `abort` call here: https://github.com/qemu/qemu/blob/master/target/riscv/csr.c#L99 +2. Build tip-of-tree QEMU for qemu-system-riscv64. +3. Use https://github.com/google/android-riscv64#can-i-try-it to build the Android RISC-V emulator. When launching the emulator, use the '-qemu_binary_dir' option to point to the directory containing the QEMU built in the previous step. +4.

Running QEMU was the only option working for people on M-series Macs to run steamcmd in a container reliably over Docker Desktop as those CPUs don't have 32-bit support.

problem: +Assert failure in `usb_ep_get` : Assertion `pid == USB_TOKEN_IN || pid == USB_TOKEN_OUT` failed. + +The TD PID needs to be either `USB_TOKEN_IN` or `USB_TOKEN_OUT` in `usb_ep_get`, but in the caller `uhci_handle_td` it may be `USB_TOKEN_SETUP`. + +An unprivileged guest user may be able to reach the assertion, I think this bug is quite akin to CVE-2024-3567 (https://gitlab.com/qemu-project/qemu/-/issues/2273) : + +Users are not directly able to craft URBs, however as a user, one might be able to find a kernel path that would send a TD with PID `USB_TOKEN_SETUP` to QEMU (which is called `USB_PID_SETUP` in Linux). +For instance in the Linux Kernel, `uhci_submit_control` in `drivers/usb/host/uhci-q.c:789` does link a `USB_PID_SETUP` TD to the URB. +Steps to reproduce: +Minimized reproducer: + +``` +cat << EOF | ./qemu/build2/qemu-system-x86_64 -machine q35 -nodefaults \ +-device \

SCOMC and SCOMD are both 64-bit read/write SPRs and are used for SCOM Control and SCOM Data respectively. The interface is implemented as a direct connection to the parallel-to-serial converter, which handles the arbitration between the core and service processor. + +11.6.2 Operating System Protocol to Access SCOM SPRs In the PowerPC 970FX, SCOMC and SCOMD are complete operations. They do not require a software protocol in order to function properly except to disable external (asynchronous) interrupts. Software must check the error bits after performing an SCOMC to ensure that the command successfully completed.

This is specific choice on my part to make sure the kernel code runs with machine address and user code runs with virtual addresses. This is different than Linux, NetBSD or other OSes I know that run the kernel in supervisor mode. When running in machine mode and running kernel code, I get a a trap. My error message looks like this: + +PANIC: Unexpected trap from machine mode! + mepc = 0x800002a8, mcause = 2, mtval=0xe78023 mstatus=0xa00000080 + +Notice, the mstatus bits show the trap was due to a privileged instruction being run by a "user" mode instruction. In the "assignment version" used for the above, no user code was run. It was just multiple threads running in machine mode. Also, the trap function is run with the MPP bits of 0, so even trying to recover from this trap can't be done as trying to manipulate the mstatus will generate yet again another trap to the same place and still running in "user" mode. + +This change does not happen on every run. It happens more consistently recently when trying to debug the kernel with gdb. This must be a race condition somewhere. + +The kernel is written in C++ with C libraries. +Steps to reproduce: +1. You will need to have access to my kernel and possibly my code base. This is a code base that I want to stay at WWU (Western Washington University). +2. Give the command "bmake run". It often completes with no problems, but if you run it often enough it will generate this trap from "machine mode". The example above had four good runs with no errors and on the fifth run it blew up. There is not guaranteed way to get this to have a problem. (This is why I haven't reported it before, I kept trying to get a minimal code set that had the problem, but I couldn't do it.) +Additional information: +This is a bug has been a problem for several years. It didn't strike very often on some versions of qemu. I think one of the 7.x.x versions happened not too often. But with newer, faster machines and a different version of Linux, this bug has become a big problem for me and my students. + +Here is a sample bad run: (All compilation has been done before so this just makes sure everything is up-to-date and then runs qemu-system-riscv64. In this assignment, no user mode code is being run. Threads are all running in machine mode for the entire time. I am getting clock interrupts on the CPU, but that does not appear to be the problem.) + +$ bmake run +if !

Please excuse reporting deficiencies, I'll endeavour to fix them as best I can once pointed out. + +In my spare time, I help out for the packaging effort in the [conda-forge](https://conda-forge.org/) ecosystem, which is mostly associated/attached to the python world, but - in contrast to the vanilla python tools - also deals with non-python dependencies, and in particular has strong enough abstractions to deal with ABI-issues and generally provides much better integration than the packages on PyPI. + +This strength of abstraction has also allowed conda-forge to publish artefacts for many more architectures than most projects are commonly able to provide precompiled binaries for. Due to the lack of (reliable) public CI for aarch64 & ppc64le, these packages are mostly cross-compiled from linux-x86. Where cross compilation is not possible, the packages are compiled in emulation through QEMU, coming through https://github.com/multiarch/qemu-user-static (this is the part of the infrastructure I don't fully understand myself...). The full infrastructure is somewhat involved, but should not be relevant (hopefully) to the issue at hand (see instructions below) - and even if that turns out to be the case, that would be a great information gain as well. + +In either case, the tests for the package (ideally comprising the entire upstream test suite) are then run in emulation. + +Two of the so-called "feedstocks" I co-maintain are for [numpy](https://github.com/conda-forge/numpy-feedstock) and [scipy](https://github.com/conda-forge/scipy-feedstock), and there have been persistent issues with running the test suite in emulation on PPC (interestingly, the same setup on a different architecture - aarch64 - has no problems). However, the compiled artefacts on PPC run fine on native hardware. + +Said otherwise, it appears numpy/scipy are exercising QEMU enough to uncover some bugs. I've seen similar problems also in other packages (e.g. the cvxpy-stack), reinforcing the impression that this is a QEMU issue, and not one on the level of the individual packages. + +Depending on the exact combination of python version, the result of the numpy test suite might be as follows: +``` +320 failed, 18900 passed, 361 skipped, 36 xfailed, 9 xpassed, 144 warnings in 2516.49s (0:41:56) +``` + +Looking at the test failures, sometimes the results are garbage +``` +> assert_array_max_ulp(x, x+eps, maxulp=20) +E AssertionError: Arrays are not almost equal up to 20 ULP (max difference is 8.55554e+08 ULP) + +eps = 1.1920929e-07 +self = <numpy.testing.tests.test_utils.TestULP object at 0x401ec8beb0> +x = array([ 2.3744986e-38, nan, 2.2482052e-15, 7.5780330e+28, + nan, nan, 5.8310814e+29, -5.6511531e+24, + 1.0010809e+00, 1.0101526e+00], dtype=float32) +``` +sometimes the values are permuted +``` +> assert_array_equal(actual, desired) +E AssertionError: +E Arrays are not equal +E +E x and y nan location mismatch: +E x: array([0.000000e+00, 6.704092e-39, 9.000000e+00, 2.350989e-38, +E 0.000000e+00, 0.000000e+00, 0.000000e+00, 0.000000e+00, +E 6.772341e-39, nan], dtype=float32) +E y: array([6.704092e-39, 6.772341e-39, 0.000000e+00, 0.000000e+00, +E 0.000000e+00, 0.000000e+00, nan, 2.350989e-38, +E 2.000000e+00, 7.000000e+00], dtype=float32) +``` +sometimes the results are fundamentally different (zero vs. non-zero) +``` +> raise AssertionError(msg) +E AssertionError: +E Arrays are not almost equal to 6 decimals +E +E Mismatched elements: 72 / 216 (33.3%) +E Max absolute difference: 1. +E Max relative difference: 1. +E x: array([[[[[0., 0., 0.], +E [0., 0., 0.], +E [0., 0., 0.]],... +E y: array([[[[[1., 0., 0.], +E [0., 1., 0.], +E [0., 0., 1.]],... +``` + +I don't know where it goes wrong, but it's not just a little tolerance violation.

(The +iteration count for triggering the problem 50% of the runs is not the +same when using the kernel Linux and FreeBSD's kernel, presumably due +to different ticks.) + +The bug happens much more frequently for a loaded system; in fact, the +loop count can be radically decreased if two instances of the trigger +program are run in parallel. \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1165383 b/results/classifier/mode-deepseek-r1:32b/output/user/1165383 new file mode 100644 index 000000000..f2a83f7dd --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1165383 @@ -0,0 +1,5 @@ + + +executable qemu-1.4.0/i386-linux-user/./qemu-i386 gives a segmentation fault + +executable qemu-1.4.0/i386-linux-user/./qemu-i386 gives a segmentation fault \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1170 b/results/classifier/mode-deepseek-r1:32b/output/user/1170 new file mode 100644 index 000000000..5e2635a75 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1170 @@ -0,0 +1,58 @@ + + +Unable to compile in Ubuntu 22.04, at compiling linux-user_arm_nwfpe_double_cpdo.c.o +Description of problem: +Compiling of QEMU 7.1.0-rc3 stops here for me: +``` +[7172/9855] Compiling C object libqemu-armeb-linux-user.fa.p/linux-user_arm_nwfpe_double_cpdo.c.o +FAILED: libqemu-armeb-linux-user.fa.p/linux-user_arm_nwfpe_double_cpdo.c.o +cc -m64 -mcx16 -Ilibqemu-armeb-linux-user.fa.p -I. -I.. -Itarget/arm -I../target/arm -I../common-user/host/x86_64 -I../linux-user/include/host/x86_64 -I../linux-user/include -Ilinux-user -I../linux-user -Ilinux-user/arm -I../linux-user/arm -Iqapi -Itrace -Iui -Iui/shader -I/usr/include/capstone -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -fdiagnostics-color=auto -Wall -Winvalid-pch -std=gnu11 -O2 -g -isystem /home/andrea/Downloads/qemu-7.1.0-rc3/linux-headers -isystem linux-headers -iquote . -iquote /home/andrea/Downloads/qemu-7.1.0-rc3 -iquote /home/andrea/Downloads/qemu-7.1.0-rc3/include -iquote /home/andrea/Downloads/qemu-7.1.0-rc3/tcg/i386 -pthread -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -Wstrict-prototypes -Wredundant-decls -Wundef -Wwrite-strings -Wmissing-prototypes -fno-strict-aliasing -fno-common -fwrapv -Wold-style-declaration -Wold-style-definition -Wtype-limits -Wformat-security -Wformat-y2k -Winit-self -Wignored-qualifiers -Wempty-body -Wnested-externs -Wendif-labels -Wexpansion-to-defined -Wimplicit-fallthrough=2 -Wno-missing-include-dirs -Wno-shift-negative-value -Wno-psabi -fstack-protector-strong -fPIE -isystem../linux-headers -isystemlinux-headers -DNEED_CPU_H '-DCONFIG_TARGET="armeb-linux-user-config-target.h"' '-DCONFIG_DEVICES="armeb-linux-user-config-devices.h"' -MD -MQ libqemu-armeb-linux-user.fa.p/linux-user_arm_nwfpe_double_cpdo.c.o -MF libqemu-armeb-linux-user.fa.p/linux-user_arm_nwfpe_double_cpdo.c.o.d -o libqemu-armeb-linux-user.fa.p/linux-user_arm_nwfpe_double_cpdo.c.o -c ../linux-user/arm/nwfpe/double_cpdo.c +during RTL pass: expand +../linux-user/arm/nwfpe/double_cpdo.c: In function ‘DoubleCPDO’: +../linux-user/arm/nwfpe/double_cpdo.c:232:1: internal compiler error: Segmentation fault + 232 | } + | ^ +0x7fe5b824251f ??? + ./signal/../sysdeps/unix/sysv/linux/x86_64/libc_sigaction.c:0 +0x7fe5b8229d8f __libc_start_call_main + ../sysdeps/nptl/libc_start_call_main.h:58 +0x7fe5b8229e3f __libc_start_main_impl + ../csu/libc-start.c:392 +Please submit a full bug report, +with preprocessed source if appropriate. +Please include the complete backtrace with any bug report. +See <file:///usr/share/doc/gcc-11/README.Bugs> for instructions. +ninja: build stopped: subcommand failed. +make[1]: *** [Makefile:162: run-ninja] Error 1 +make[1]: Leaving directory '/home/andrea/Downloads/qemu-7.1.0-rc3/build' +make: *** [GNUmakefile:11: all] Error 2 +``` + +Configure Output: +[Configure_Output.txt](/uploads/40055846573b79cc2817d5cb338e18c1/Configure_Output.txt) + +Compiles on 7.0.0. +Steps to reproduce: +1.

The ARM device does not need to have `qemu-user-static`, nor `qemu-user-static-binfmt` installed because it does not need to emulate an aarch64 CPU. +Steps to reproduce: +There are two ways to replicate this.

This will allow us to `chroot` into the Arch Linux ARM image (technically `chroot` will work since we don't need to use `pacman` for anything with this method, so you could skip `arch-install-scripts` if you prefer). `sudo pacman -S qemu-user-static qemu-user-static-binfmt arch-install-scripts`. + - 3) I put the chroot environment in a state where you can simply run the following command to build the one file that fails.

If you copy your `chroot` over to a real ARM device (like an Raspberry PI 3 or 4 or PinePhone) and run the compile command from step (3), it will be successful. This suggests that everything is setup correctly, but there is a bug in QEMU that causes the c++ compiler to fail. + +2. You can download an Arch Linux ARM image from archlinuxarm.org and chroot into that. Then attempt to build the `nheko` AUR package. (This way requires extra work, but you can use this if you don't trust my chroot archive). + - 1) Download Arch Linux ARM to your X86_64 PC. The Raspberry PI 3/4 image should work. `http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-aarch64-latest.tar.gz`. Signatures are available on archlinuxarm.org. + - 2) Extract the tar archive: `mkdir chroot; sudo tar -xf ArchLinuxARM-rpi-aarch64-latest.tar.gz -C chroot` (this will extract to the `chroot` folder in your current working directory. + - 3) On your PC, install `qemu-user-static` and `qemu-user-static-binfmt` and `arch-install-scripts`. This will allow us to `chroot` into the Arch Linux ARM image (using the `arch-chroot` because we will need to install packages with pacman in the chroot environment). `sudo pacman -S qemu-user-static qemu-user-static-binfmt arch-install-scripts`. + - 4) Now, we can bindmount the `chroot` directory to itself so `arch-chroot` is happy. `sudo mount --bind chroot/ chroot/` + - 5) Enter the chroot: `sudo arch-chroot chroot/` + - 6) At this point, we need to get our build environment setup. Let's start by installing `git`, `base-devel`, `screen` and `vim`. `pacman -S git base-devel screen vim`. I use screen to have one terminal for the root user to install stuff and one for the `builder` user that we will create for building packages as `makepkg` does not particularly like to run as root. + - 7) Add the builder user and create its home folder: `useradd builder; mkdir /home/builder; chown builder:builder /home/builder`. + - 8) You could maybe use an AUR helper to build the following packages, but they don't have the 'aarch64' flag, so they will throw an error when you try to compile them. Thus, I use `makepkg` manually with the `--ignorearch` flag to ignore the architecture of the chroot environment (they are fully compatible with aarch64, just not marked as such). Thus, run `su -l builder` to switch to the builder user, `mkdir packages` to create the packages folder, and then clone the following AUR packages into this folder and build them: `coeurl lmdbxx mtxclient nheko tweeny`. These are dependencies for `nheko`. The process is `git clone https://aur.archlinux.org/<PACKAGENAME>.git`, then `cd PACKAGENAME`, then `makepkg --ignorearch`, then (as the root user in the chroot environment - can use sudo if you set it up) `pacman -U PACKAGENAME.PACKAGEVERSION.pkg.tar.xz` (you can type the package name and then use tab to autocomplete the exact package name). They will all compile just fine and install correctly. + - 9) Now, do the same for the AUR package `nheko`. Notice that it will start to compile, but the error shown above will be printed on the screen after a while. If you copy your `chroot` over to a real ARM device (like an Raspberry PI 3 or 4 or PinePhone) and `arch-chroot` into it and attempt the compile again, it will be successful. This suggests that everything is setup correctly, but there is a bug in qemu that causes the c++ compiler to fail. This is known to break in nheko version `0.10.2-1`. You can get to this by running `git checkout d83124fbffe86d7f875bf8e56834ae98cc21160c` after you clone the `nheko` AUR build script. This is the current latest version as of writing this, but this may change in the future and the bug may no longer show up. If it doesn't, run that `git checkout` command. +Additional information: +After using the `-strace` option in `qemu-aarch64-static` (which has to be copied from the host system to the chroot for this to work: `sudo cp /usr/bin/qemu-aarch64-static chroot/usr/bin/qemu-aarch64-static`), I determined that `c++` was running `/usr/lib/gcc/aarch64-unknown-linux-gnu/12.1.0/cc1plus`, which segfaulted.

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().

I also confirmed using qemu's -singlestep debug option that the segfault occurs during the mremap syscall. + +If you save the source below to mremapbug.c, the following should reproduce the issue given you have gcc-multilib: + +gcc -m32 mremapbug.c +# works +./a.out +# segfault +qemu-i386 a.out + +If you can also compile to arm, the same thing happens when running "qemu-arm a.out".

I investigated this for about 2 weeks, manually trying to trace the call stack, only to find that we seemingly crash in a bad shift instruction. Originally intended to be an shr_i64 generated to an RLDICL, we end up with an all ones(-1) c value, which gets thrown to the macro for generating the MB, and replaces the instruction with mostly ones. This new instruction, FFFFFFE0 is invalid on ppc64le, and crashes in a host SIGILL in codegen_buffer. I tried to see if the output of translate.c had this bad instruction, but all I got were two (shr eax, cl) instructions, and upon creating a test program with shr (eax, cl) in it, nothing happened. Then figuring that there was nothing actually wrong with the instruction in the first place, I turned my eye to the optimizer, and completely disabled constant folding for arithmetic instructions. This seemed to actually resolve the issue, and then I slowly enabled constant folding again on various instructions only to find that enabling not on the shifts, but on subtraction seemed to cause the bug to reappear. I am bewildered and frankly at this point I'm not sure I have a chance in hell of figuring out what causes it, so I'm throwing it here. \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1878501 b/results/classifier/mode-deepseek-r1:32b/output/user/1878501 new file mode 100644 index 000000000..ca0d63396 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1878501 @@ -0,0 +1,33 @@ + + +qemu-i386 does not define AT_SYSINFO + +qemu-i386 does not define the AT_SYSINFO auxval when running i386 Linux binaries. + +On most libcs, this is properly handled, but this is mandatory for the i686 Bionic (Android) libc or it will segfault. + +This is due to a blind assumption that getauxval(AT_SYSINFO) will return a valid function pointer: + +The code varies from version to version, but it looks like this: + +void *__libc_sysinfo; +// mangled as _Z19__libc_init_sysinfov +void __libc_init_sysinfo() { + bool dummy; + // __bionic_getauxval = getauxval + __libc_sysinfo = reinterpret_cast<void *>(__bionic_getauxval(AT_SYSINFO, dummy)); +} + +A simple way to reproduce is to compile a basic C program against the NDK: + +int main(void) { return 0; } + +$ i686-linux-android-clang -static empty.c -o empty +$ qemu-i386 -cpu max ./empty +qemu: uncaught target signal 11 (Segmentation fault) - core dumped +Segmentation fault + +The place where it segfaults is misleading: It will, at least on the current NDK, crash on __set_thread_area, this is due to it calling a function pointer to __libc_sysinfo returned by __kernel_syscall. + +QEMU 4.1.1 (aarch64) +Pixel 2 XL via Termux \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1878627 b/results/classifier/mode-deepseek-r1:32b/output/user/1878627 new file mode 100644 index 000000000..38fbd6338 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1878627 @@ -0,0 +1,13 @@ + + +audio/mixeng build failure using Clang 10 + +When building with Clang 10 on Fedora 32, we get: + + CC audio/mixeng.o + audio/mixeng.c:274:34: error: implicit conversion from 'unsigned int' to 'float' changes value from 4294967295 to 4294967296 [-Werror,-Wimplicit-int-float-conversion] + static const float float_scale = UINT_MAX / 2.f; + ^~~~~~~~ ~ + /usr/lib64/clang/10.0.0/include/limits.h:56:37: note: expanded from macro 'UINT_MAX' + #define UINT_MAX (__INT_MAX__ *2U +1U) + ~~~~~~~~~~~~~~~~~^~~ \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1878628 b/results/classifier/mode-deepseek-r1:32b/output/user/1878628 new file mode 100644 index 000000000..351ec521a --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1878628 @@ -0,0 +1,10 @@ + + +linux-user/mmap build failure using Clang 10 + +When building with Clang 10 on Fedora 32, we get: + + CC linux-user/mmap.o + linux-user/mmap.c:720:49: error: result of comparison 'unsigned long' > 18446744073709551615 is always false [-Werror,-Wtautological-type-limit-compare] + if ((unsigned long)host_addr + new_size > (abi_ulong)-1) { + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~ \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1880225 b/results/classifier/mode-deepseek-r1:32b/output/user/1880225 new file mode 100644 index 000000000..d1b12f976 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1880225 @@ -0,0 +1,139 @@ + + +Emulation of some arm programs fail with "Assertion `have_guest_base' failed." + +This issue is observer with QEMU ToT, checked out around May 15th (but I believe it is present in current master too), and wasn't present in QEMU v5.0.0. + +I am using 32-bit Intel(R) Pentium(R) M processor 1.73GHz host. + +Arm cross-compiler is a standard cross-compiler that comes with Debian-based distributions, and gcc version is: + +$ arm-linux-gnueabi-gcc --version +arm-linux-gnueabi-gcc (Debian 8.3.0-2) 8.3.0 + +Compile this program with cross compiler: + +$ arm-linux-gnueabi-gcc -O2 -static toupper_string.c -o toupper_string-arm + +Emulation with QEMU v5.0.0 is correct, and gives expected output: + +$ ~/Build/qemu-5.0.0/build-gcc/arm-linux-user/qemu-arm ./toupper_string-arm +CONTROL RESULT: (toupper_string) + nwlrbbmqbhcdarz owkkyhiddqscdxr jmowfrxsjybldbe fsarcbynecdyggx xpklorellnmpapq + NWLRBBMQBHCDARZ OWKKYHIDDQSCDXR JMOWFRXSJYBLDBE FSARCBYNECDYGGX XPKLORELLNMPAPQ + +While, in case of QEMU master it fails: + +$ ~/Build/qemu-master/build-gcc/arm-linux-user/qemu-arm ./toupper_string-arm +qemu-arm: /home/rtrk/Build/qemu-master/linux-user/elfload.c:2294: probe_guest_base: Assertion `have_guest_base' failed. +Aborted + +There are many other programs that exibit the same behavior.

For example +`cargo` (a tool for the Rust compiler). + +It does not matter if there are a lot of calls to fork. What seems to matter most is that there are many threads running. So this happens more often on a CPU with a massive number of cores, and if nothing else is really running. The hang happens in the child process of the fork. + +To reproduce the problem, I have attached an example of C++ program to run through qemu-user. + +Here are the stacks of the child processes that hanged.

Allocations are done through g_slice. g_slice has a global state that is not fork safe. + +So even though the cpu thread is set to exclusive before forking, it is not enough. Because there are other uses of glib data structures that are not part of the cpu loop (I think). So it seems not to be synchronized by `start_exclusive`, `end_exclusive`. + +So if one of the use of glib data structure is used during the fork, an allocation might lock a mutex in g_slice. + +When the cpu loop resumes in forked process, then the use of any glib data structure might just hang on a locked mutex in g_slice. + +So as a work-around we have starting using is setting environment `G_SLICE=always-malloc`. This resolves the hangs. + +I have opened an issue upstream: https://gitlab.gnome.org/GNOME/glib/-/issues/2326 + +As fork documentation says, the child should be async-signal-safe. However, glibc's malloc is safe in fork child even though it is not async-signal-safe. So it is not that obvious where the responsability is. Should glib handle this case like malloc does? Or should qemu not use glib in the fork child? \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/1915925 b/results/classifier/mode-deepseek-r1:32b/output/user/1915925 new file mode 100644 index 000000000..cca2f4e90 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/1915925 @@ -0,0 +1,19 @@ + + +ARM semihosting HEAPINFO results wrote to wrong address + +This affects latest development branch of QEMU. + +According to the ARM spec of the HEAPINFO semihosting call: + +https://developer.arm.com/documentation/100863/0300/Semihosting-operations/SYS-HEAPINFO--0x16-?lang=en + +> the PARAMETER REGISTER contains the address of a pointer to a four-field data block. + +However, QEMU treated the PARAMETER REGISTER as pointing to a four-field data block directly. + +Here is a simple program that can demonstrate this problem: https://github.com/iNvEr7/qemu-learn/tree/newlib-bug/semihosting-newlib + +This code links with newlib with semihosting mode, which will call the HEAPINFO SVC during crt0 routine.

It is a user-mode fault so the OS simply terminated the faulting process, OS remains fully functional after the fault and the same fault can be repeated. Should be extremely helpful in debugging.

It means that the implementation of `qemu_plugin_read_register()` gets the same value several times in a row, instead of a new value each time. diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/222 b/results/classifier/mode-deepseek-r1:32b/output/user/222 new file mode 100644 index 000000000..05fcacdfe --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/222 @@ -0,0 +1,3 @@ + + +Reading /proc/self/task/<pid>/maps is not remapped to the target diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2220 b/results/classifier/mode-deepseek-r1:32b/output/user/2220 new file mode 100644 index 000000000..e70952a97 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2220 @@ -0,0 +1,530 @@ + + +Intermittent QEMU segfaults on x86_64 with TCG accelerator +Description of problem: +Recently(-ish) in our upstream systemd CI we started seeing an uptrend of QEMU segfaults when running our integration tests.

The goal is to run a project built on top of one of FreeRTOS' official demo ports that target the 'virt' QEMU board. I ran across a few weird behaviors where code execution would just hang at some point (QEMU would keep execution but the expected terminal output would never come up). I don't have sufficient knowledge to tell whether the issue is with the FreeRTOS port, the RISC-V gnu toolchain or QEMU itself, hence why I am raising my hand for help on all related channels. + +This [repository](https://bitbucket.org/softcps-investigacao-risc-v/freertos-riscv-bugs/src/master/) contains more details and a sample project that illustrates well one of the problems I've been getting lately (I also give more context about it [here](https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1434)). It basically goes like this: the program **executes fine** when a certain code snippet is encapsulated **within a function**, but "**crashes**" (i.e. hangs) when the same snippet is placed **directly in the main code**: + +```c +for(int i=0; i < NUMBER_OF_ITEMS; i++){ + createAndPushItem(i); + + // the function above does the exact same thing as the commented code below + // yet, the commented code does not work and will crash the program. but why?? + + // int index = priorities[i]; + // void *value = (void *) getValue(i + 1); + // LinkedListItem_t *item = createItem(index, value); + // if(item){ + // push(item, &list); + // } +} +``` + +The scope shouldn't matter at all here, since there is no local variable being used or anything like that. I have tested workarounds like removing compiling optimization (i.e. changing -Os for -O0) and using regular malloc() instead of FreeRTOS' dynamic allocation API, but all without success. Note that even though the project is build on top of the FreeRTOS demo port, no RTOS functionality is used within this code to make it as simple as it gets. +Steps to reproduce: +1. clone this [repository](https://bitbucket.org/softcps-investigacao-risc-v/freertos-riscv-bugs/src/master/) +2. follow the readme to install the toolchain +3. follow the readme to compile the program and run it +Additional information: +The expected output is supposed to be: + + + +but when one decides to use the commented snippet instead of the function, the program hangs right before sorting the linked list for the first time: + + diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2232 b/results/classifier/mode-deepseek-r1:32b/output/user/2232 new file mode 100644 index 000000000..3f345b3d5 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2232 @@ -0,0 +1,3 @@ + + +ui/qemu.desktop is nonconformant with the desktop entry specification diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2238 b/results/classifier/mode-deepseek-r1:32b/output/user/2238 new file mode 100644 index 000000000..73067e068 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2238 @@ -0,0 +1,49 @@ + + +The `rw` parameter of `qemu_plugin_register_vcpu_mem_cb()` is not properly honored +Description of problem: +The `rw` parameter of `qemu_plugin_register_vcpu_mem_cb()` is not properly honored. +Steps to reproduce: +1.

This is not only a violation of Linux's policy never to map anything at the first page of any virtual address space, but also a cause of confusion (and segfaults) within certain libcs; though I only tested with musl. Musl [interprets a NULL base address](https://elixir.bootlin.com/musl/v1.2.4/source/ldso/dlstart.c#L105) as the dynamic linker being invoked directly, causing it to compute its base address incorrectly. + +The problem arises in `load_elf_image()`, which chooses a `load_addr` of 0 for the ELF interpreter (i.e. the musl dynamic loader). This is passed to `target_mmap()`. I do not know whether `target_mmap()` is meant to follow the POSIX rule that (in absence of `MAP_FIXED`) "All implementations interpret an *addr* value of 0 as granting the implementation complete freedom in selecting *pa*" or if 0 is requesting 0. + +QEMU's usermode mmap() implementation translates the guest address to a host address (this is effectively a no-op with `guest_base == 0`) and passes it along to the host Linux. This means that, when `guest_base == 0`, a NULL input address means "put it anywhere," but when `guest_base != 0`, NULL means "put it at (guest address) 0." +Steps to reproduce: +1. Download a rootfs of Alpine Linux AArch64. +2. Install `gcc` (with `apk add gcc`) in the rootfs. `gcc` is not compiled as PIC, making QEMU use a nonzero `guest_base`. +3. Attempt to run `gcc` within the rootfs via QEMU. +Additional information: +I am interested in submitting a MR that fixes this issue, but I do not know which of 4 possible solutions is preferred: + +1. Modify `load_elf_image()` to ensure that `load_addr` is never NULL. +2. Modify `target_mmap()` so that NULLs are passed to the kernel as NULLs. +3. Modify the guest<->host translation facilities (`g2h_untagged` et al) to translate NULL as NULL. Overwhelmingly, a NULL pointer semantically means "there is no pointer here" and not "a pointer to the zeroth address," so treating these as valid addresses in the translation functions is arguably going against the grain. +4. When a nonzero `guest_base` is selected, reserve the first page of the guest VA space, so that the host kernel cannot accidentally put anything there. + +Here is my local patch that implements item 2 above, which indeed stops the segfaults for me: +<details><summary>Patch</summary> + +```diff +diff --git a/linux-user/mmap.c b/linux-user/mmap.c +index be3b9a6..dad29ef 100644 +--- a/linux-user/mmap.c ++++ b/linux-user/mmap.c +@@ -559,7 +559,7 @@ static abi_long mmap_h_eq_g(abi_ulong start, abi_ulong len, + int host_prot, int flags, int page_flags, + int fd, off_t offset) + { +- void *p, *want_p = g2h_untagged(start); ++ void *p, *want_p = start ? g2h_untagged(start) : 0; + abi_ulong last; + + p = mmap(want_p, len, host_prot, flags, fd, offset); +@@ -609,7 +609,7 @@ static abi_long mmap_h_lt_g(abi_ulong start, abi_ulong len, int host_prot, + int mmap_flags, int page_flags, int fd, + off_t offset, int host_page_size) + { +- void *p, *want_p = g2h_untagged(start); ++ void *p, *want_p = start ? g2h_untagged(start) : 0; + off_t fileend_adj = 0; + int flags = mmap_flags; + abi_ulong last, pass_last; +@@ -739,7 +739,7 @@ static abi_long mmap_h_gt_g(abi_ulong start, abi_ulong len, + int flags, int page_flags, int fd, + off_t offset, int host_page_size) + { +- void *p, *want_p = g2h_untagged(start); ++ void *p, *want_p = start ? g2h_untagged(start) : 0; + off_t host_offset = offset & -host_page_size; + abi_ulong last, real_start, real_last; + bool misaligned_offset = false; +``` +</details> diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2371 b/results/classifier/mode-deepseek-r1:32b/output/user/2371 new file mode 100644 index 000000000..c14718b57 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2371 @@ -0,0 +1,54 @@ + + +A bug in RISC-V froundnx.h instruction +Description of problem: +According to the RISCV ISA manual, the froundnx.h instruction rounds a half-precision floating-point number in the source register to an integer and writes the integer, represented as a half-precision floating-point number, to the destination register.

Get a coreutils built for riscv64 (Let's say it can be found in `riscv64-coreutils/bin`) +3. Run it with something like `riscv64-coreutils/bin/cat <&- | xxd | head` (`xxd | head` to catch the binary output) + +The correct behavior is (You can see by running the native `cat <&-`): + +``` +cat: -: Bad file descriptor +cat: closing standard input: Bad file descriptor +``` + +Instead, the executable `cat` itself is dumped to stdout. + +Perhaps slightly more clear is `riscv64-coreutils/bin/ls -l /proc/self/fd <&-` which shows fd 0 unexpectedly pointing to the coreutils executable. +Additional information: +I'm interested in writing a patch to fix this issue but I'm uncertain how to proceed. This is what I've found so far: + +In `linux-user/main.c` if (effectively) `getauxval(AT_EXECFD)` is 0 it's treated as nonexistent. (https://gitlab.com/qemu-project/qemu/-/blob/0d9f1016d43302108d33d1268304a06cc3fb2021/linux-user/main.c#L758-765) + +```c + execfd = qemu_getauxval(AT_EXECFD); + if (execfd == 0) { + execfd = open(exec_path, O_RDONLY); + if (execfd < 0) { + printf("Error while loading %s: %s\n", exec_path, strerror(errno)); + _exit(EXIT_FAILURE); + } + } +``` + +However as we've seen `getauxval(AT_EXECFD)` can have 0 as a valid value. + +`qemu_getauxval` in `util/getauxval.c` implements several strategies to get the auxv, but doesn't currently give a way to distinguish not found and 0. FreeBSD `elf_aux_info` has `EINVAL` and `ENOENT` error codes but it's ignored here. On Linux, glibc sets `errno` to `ENOENT` to distinguish the two cases but only on glibc >= 2.19. Musl's `getauxval` has always had setting `errno` to `ENOENT`. + +Once we add a proper "`AT_EXECFD` doesn't exist" check this will no longer be a problem since (IIUC) `execfd` will eventually be closed after loading. How should we add "not found" support to `qemu_getauxval`? Is just simply relying on libc's `getauxval` setting `errno` okay? diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2457 b/results/classifier/mode-deepseek-r1:32b/output/user/2457 new file mode 100644 index 000000000..76d188cef --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2457 @@ -0,0 +1,3 @@ + + +Building plugin sources doesn't produce any output to 'make' diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2458 b/results/classifier/mode-deepseek-r1:32b/output/user/2458 new file mode 100644 index 000000000..bf09250a4 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2458 @@ -0,0 +1,3 @@ + + +Documentation build fails with Sphinx 8 diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2459 b/results/classifier/mode-deepseek-r1:32b/output/user/2459 new file mode 100644 index 000000000..5f22c2766 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2459 @@ -0,0 +1,3 @@ + + +Qemu in termux network bug diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2460 b/results/classifier/mode-deepseek-r1:32b/output/user/2460 new file mode 100644 index 000000000..f741142e0 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2460 @@ -0,0 +1,10 @@ + + +Significant performance degradation of qemu-x86_64 starting from version 3 on aarch64 +Description of problem: +When I ran CoreMark with different qemu user-mode versions，guest x86-64-> host arm64, I found that the performance was highest with QEMU 2.x versions, and there was a significant performance degradation starting from QEMU version 3.

Compile `test.bin` using this command: `gcc-12 -O2 -no-pie ./test.c -o ./test.bin` +3. Run QEMU using this command: `qemu-x86_64 ./test.bin` +4. The program, runs on top of the buggy QEMU, prints the value of R8 as `00 00 00 00 00 00 00 00`. It should print `ff ff ff ff ff ff ff ff` after the bug is fixed. +Additional information: + diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/2498 b/results/classifier/mode-deepseek-r1:32b/output/user/2498 new file mode 100644 index 000000000..867dbb39b --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/2498 @@ -0,0 +1,53 @@ + + +m68k: fpu: fmovem with multiple control registers has incorrect in memory order +Description of problem: +It looks like the order of reading/writing registers is currently incorrect for `fmovem` with multiple fpu control registers. + +According to the manual: + +``` +The +registers are always moved in the same order, regardless of the addressing mode +used;

Then only x86_64 and x86 can be called normally, while programs of other architectures (arm64, arm, riscv64, etc.) will return ENOENT errors. + +I first encountered this problem when trying to run lxc-attach with qemu-aarch64. Its reference is [lxc/stable-6.0/src/include/fexecve.c#L30](https://github.com/lxc/lxc/blob/stable-6.0/src/include/fexecve.c#L30), which is the implementation of the fexecve function. So I wrote a simple test and compiled it with `x86_64/aarch64-linux-gnu-gcc -static test.c -o test`. execveat works fine when running natively or using qemu-x86_64/qemu-i386. When running versions for other architectures, using AT_EMPTY_PATH will result in ENOENT (No such file or directory); use /proc/self/fd/%d as the pathname and execve, it will work fine (like the rest part of the fexecve function). If binfmt_misc is turned off and run forign architectures ver, both calls will result in ENOEXEC (Exec format error). +Steps to reproduce: +1. Install qemu-user and binfmt_misc.

This was not happening with qemu-4.2 (on Ubuntu 20.04). This is also not happening when using accel=kvm instead. The issue has been first noticed on Debian 11 (Bullseye) with the versions above, but it is happening in the same way on Centos 8 Stream, Ubuntu 21.10 and a pre-release version of Ubuntu 22.04.

As these instructions use a new flavor of SVE scatter/gather loads (vector plus scalar) which SVE LD1SB does not support, I wonder if the LD1SB handler simply decodes it as the wrong instruction and treats it as a (scalar plus vector) instruction, which LD1SB does support, but whose address calculation is completely different. diff --git a/results/classifier/mode-deepseek-r1:32b/output/user/829 b/results/classifier/mode-deepseek-r1:32b/output/user/829 new file mode 100644 index 000000000..4120e1e0e --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/output/user/829 @@ -0,0 +1,16 @@ + + +user space emulation: openat() seems to defeat sysroot path translation +Description of problem: +It appears that the user space emulation code is doing some path manipulation of some syscalls to sometimes prefix them with the sysroot.

From what I know, QEMU can run in user-mode or system-mode. User-mode emulation typically emulates individual CPU instructions without needing full virtualization, and it's often used for cross-compiling or running binaries from other architectures on a host machine. System-mode, on the other hand, is when QEMU acts as a hypervisor, providing a full virtualized environment including hardware devices, peripherals, etc. + +The `-icount` option seems to be related to how QEMU handles virtual CPU time and timers.

Let me start by recalling what I know. + +QEMU is an emulator that can run different operating systems as guests on a host machine. It has two main modes: user mode and system mode. User-mode QEMU allows running unmodified user-space applications from one architecture on another without emulating the hardware, which means it doesn't require kernel support. On the other hand, system-mode QEMU emulates an entire computer system, including the CPU, memory, devices, and runs a full OS as a guest. + +Now, the bug report mentions that the build fails because of issues with 64-bit time_t. Time_t is a data type used to represent time in seconds since the epoch (usually January 1, 1970). In some systems, time_t can be 32 or 64 bits, which affects how dates are handled beyond certain years (like after 2038 for 32-bit systems). + +Since this is a build failure related to time_t handling, I'm thinking about where in QEMU such issues might occur. If it's during compilation of user-mode code, it could be because the user-space applications being emulated are expecting a certain size for time_t, and the host system or compiler is using a different one. Alternatively, if it's in system-mode emulation, the issue might arise when handling system calls related to time that involve 64-bit time_t. + +I also remember that QEMU has specific handling for time-related syscalls in both modes. In user-mode, it translates syscalls between the host and guest environments, so any mismatch in data types could cause issues during emulation or build time.

Build failures related to data types like time_t are often encountered in system-level code because they deal more directly with OS-specific details and syscalls that involve timestamps. Therefore, this might be a system-mode issue. + +But wait, user-mode could also face similar issues when translating time-related syscalls if the guest and host use different sizes for time_t. For example, if the host compiler uses 64-bit time_t but the guest expects 32-bit, it could cause build errors in user-mode code. + +Hmm, maybe I'm overcomplicating this. The key point is that the bug report mentions a failure to build, which points to the compilation process. QEMU's build system might have specific handling for time_t across different modes. If it's failing during build, it's likely due to some assumption in the code not being compatible with 64-bit time_t in either mode. + +Given that both modes could potentially have issues, but I need to classify this as one or the other. Since system-mode involves more low-level details and full OS emulation, which includes handling of time at a deeper level, it might be more prone to such build issues related to data type sizes. + +Alternatively, user-mode deals with application binaries that might expect certain sizes for time_t, so if the host compiler is set up differently, it could cause build problems in the user-mode part of QEMU. But I'm not sure which is more likely without more context. + +Wait, perhaps another angle: when building QEMU, the configuration and compilation process involves checking for various system characteristics, including data types like time_t. If during the configure step, the detection of 64-bit time_t isn't handled correctly in the part of the code that's compiling either user-mode or system-mode components, it could fail. + +If I think about how QEMU is structured, the system-mode parts might have more complex interactions with the host OS's time handling, especially since they're emulating devices and potentially syscalls that involve timestamps.

This suggests that perhaps the emulator is incorrectly identifying the cause of the invalid address or not properly checking for canonical form during this specific context switch scenario. + +Considering whether this is user-mode or system-mode related: The problem occurs during an interrupt handling, which involves switching privilege levels and accessing TSS structures. These are typically managed by the operating system in kernel mode. So when the CPU transitions from Ring 3 to Ring 0, it's entering a higher privilege level where more critical system operations occur. + +Moreover, TSS is part of the x86 architecture that deals with task switching and interrupt handling—both are low-level mechanisms handled by the OS kernel rather than user applications.

After resizing, they couldn't open the image because of this error, and even trying to shrink it back didn't work. + +From what I remember, qcow2 images use a L1 table (Level 1 Table) as part of their metadata structure. The L1 table keeps track of where each cluster's data is stored. If the image becomes too large, the L1 table might exceed the maximum allowed size, causing this error. + +The user mentioned that there was a commit in 2014 that fixed an issue where qemu overallocated for very large qcow2 images. However, it seems like `qemu-img resize` wasn't protected by this fix, allowing users to resize beyond safe limits. + +Now, considering whether this is a user-mode or system-mode issue. User-mode issues typically involve application-level problems, errors in programs running without special privileges, and don't usually interact with low-level hardware or kernel components. System-mode issues often involve drivers, hardware access, operating system interactions, and higher privilege operations. + +In this case, the problem arises from using a tool (`qemu-img`) that's part of QEMU, which is user-space software. The error occurs when resizing an image file, which doesn't require special privileges beyond those needed to modify the file.

This is more about application-level error handling and validation rather than system-level issues like drivers or device management. + +So, putting it all together, since the problem is with a user-space tool causing an issue when manipulating image files without requiring kernel interaction or special privileges, this should be classified as a user-mode related bug. +</think> + +user \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/reasoning/user/1593 b/results/classifier/mode-deepseek-r1:32b/reasoning/user/1593 new file mode 100644 index 000000000..00c42e2e6 --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/reasoning/user/1593 @@ -0,0 +1,13 @@ +<think> +Okay, I'm trying to classify this bug report regarding QEMU into either 'user-mode' or 'system-mode'.

The translation of instructions is a core part of the CPU emulation regardless of mode. But the classification for bug reports in QEMU often separates them into user or system based on which part they affect.

Alternatively, if it's about how the host handles the translated code, perhaps it's more system-level. + +Wait, no. The issue is that when a guest uses SIMD instructions (like NEON), QEMU isn't using the host's SIMD capabilities and instead uses scalar operations. This would affect any application running in the guest, whether under user or system mode. But since the bug report is about performance of applications, which is more related to user-mode emulation. + +Wait, perhaps I should think about how QEMU handles instruction translation.

Let me break it down step by step. + +First, the report mentions that while QEMU's scalar emulation is good, the SIMD (Single Instruction Multiple Data) emulation isn't accurate except for arm64 on x86_64. The request is about making QEMU aware of its weak points so it can handle these instructions more carefully or give up if necessary. + +Now, I need to understand what user-mode and system-mode entail in QEMU. User-mode emulation deals with running unprivileged applications, typically without needing full OS support. It's used for tasks like debugging where the application runs under QEMU but doesn't require the entire OS environment. On the other hand, system-mode involves emulating an entire system, including hardware peripherals, devices, and a full operating system. This is more about replicating a complete computing environment, which requires handling higher privilege levels and device interactions. + +In this case, the issue is about instruction emulation—specifically SIMD instructions. If QEMU isn't correctly emulating these instructions, it's likely affecting how applications run under QEMU. Since SIMD instructions are part of the CPU architecture and can be used by various applications, both user-mode and system-mode could be impacted. However, the main focus here is on the accuracy of instruction emulation during execution. + +Since the report doesn't mention anything about peripherals, devices, or OS-level issues, it seems more focused on how QEMU handles specific instructions when running code—whether it's an application (user-mode) or a full system image (system-mode). But the key point is that the problem arises during instruction emulation. + +In user-mode, applications run under QEMU without needing the full OS stack, so if SIMD isn't handled well, it would directly affect these applications. In system-mode, the issue could also cause problems but might be more about how the OS interacts with hardware through these instructions. + +However, considering that the report is about improving QEMU's awareness of its own emulation limitations and making decisions based on that (like giving up on certain instructions), this seems like it would affect both modes. But since the primary issue is instruction-level emulation without specific mention of system-level components, I'm leaning towards it being a user-mode concern because it's more about application execution accuracy. + +But wait, maybe I should think again. System-mode involves the entire OS and hardware devices, so issues with SIMD could also impact how the kernel or device drivers run. However, the report doesn't mention anything about system-level components; it's specifically about instructions not being well emulated. Therefore, even in system-mode, this would primarily affect application execution rather than OS functions. + +Hmm, maybe I'm overcomplicating it. The main point is that incorrect SIMD emulation affects how code runs under QEMU. Since both user and system modes run code through the emulator, but the report doesn't specify context about device drivers or higher privileges beyond instruction handling, perhaps it's more aligned with user-mode because it's about application-level execution. + +Alternatively, considering that in system-mode, you might have a full OS running which could also utilize SIMD instructions, but again, without specifics on device interaction, I'm not sure. The core issue is the emulator's ability to handle certain instructions correctly, which would impact any code running under QEMU, whether it's user or system mode. + +Wait, but user-mode in QEMU typically doesn't involve the full OS, so if an application uses SIMD and QEMU messes it up, that affects user-mode. System-mode includes the OS, which might have its own handling for such instructions, but if QEMU is emulating incorrectly, it could still cause issues at a higher level. + +Given all this, I think the bug report is more about how applications run under emulation, hence it's related to user-mode. +</think> + +user \ No newline at end of file diff --git a/results/classifier/mode-deepseek-r1:32b/reasoning/user/1852115 b/results/classifier/mode-deepseek-r1:32b/reasoning/user/1852115 new file mode 100644 index 000000000..413f0d1bd --- /dev/null +++ b/results/classifier/mode-deepseek-r1:32b/reasoning/user/1852115 @@ -0,0 +1,17 @@ +<think> +Okay, so I'm looking at this problem where someone is trying to build QEMU on Fedora Rawhide using the latest git version.

From what I know, qemu has two main modes: system-mode and user-mode. System-mode emulation is when qemu emulates an entire computer system, including the hardware, BIOS, etc., which allows running a full OS in a virtual environment. User-mode emulation, on the other hand, is used to run individual applications compiled for one architecture on another without emulating the whole OS.

That makes me think that there's something specific about how qemu-user is handling things that causes this crash, possibly related to resource limits or stack management. + +The additional information points out that qemu-user uses a fixed stack size and ignores RLIMIT_STACK requests. This means that any process run under qemu-user might have different stack behavior compared to native execution. On real hardware, the OS can adjust the stack size according to RLIMIT_STACK settings, but in qemu-user, it's fixed. + +So when g++ runs inside qemu-user, if the program requires more stack space than what qemu has allocated, it will cause a segmentation fault because it tries to access memory beyond the allowed stack size. On real hardware, the OS would typically allow the stack to grow as needed or enforce the RLIMIT_STACK setting correctly, preventing such an issue unless the program genuinely has a bug. + +In this case, since the problem only occurs in qemu-user and not on real hardware, it's likely due to how qemu is managing resources.
