https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293900 Bug ID: 293900 Summary: panic: dst_m ADDR is not wired Product: Base System Version: 15.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: r772577952@gmail.com Hi FreeBSD maintainers, We have discovered an issue in the kernel when fuzzing freebsd with syzkaller and our generated syscall description. This issue is reproducible on the latest release (release/15.0.0-p4, commit 8ef0ed690df2dca0cc22b827819d112f868470bb), and from the issue report I think the root cause appears to be located within the VM subsystem. The kernel console output, kernel config, and C/syz reproducers can be found at https://drive.google.com/drive/folders/15kt9ABSTSccI2V7Bhpwxj9_SrkOkt981?usp=sharing. The issue report is also listed below (symbolized by our modified syz-symbolize) to assist with the analysis: ``` TITLE: panic: dst_m ADDR is not wired CORRUPTED: false () SUPPRESSED: false MAINTAINERS (TO): [] MAINTAINERS (CC): [] panic: dst_m 0xfffffe0009028e48 is not wired cpuid = 2 time = 1773840257 KDB: stack backtrace: #0 0xffffffff81608a59 at kdb_backtrace+0x119 /usr/obj/usr/src/kern/subr_kdb.c:452 #1 0xffffffff81537d67 at vpanic+0x257 /usr/obj/usr/src/kern/kern_shutdown.c:960 #2 0xffffffff81537b05 at panic+0xb5 /usr/obj/usr/src/kern/kern_shutdown.c:887 #3 0xffffffff81dc61b3 at vm_fault_copy_entry+0xa43 /usr/obj/usr/src/vm/vm_fault.c:2172 #4 0xffffffff81dd8edd at vm_map_protect+0xfed /usr/obj/usr/src/vm/vm_map.c:0 #5 0xffffffff81dea3e1 at sys_mprotect+0x191 /usr/obj/usr/src/vm/vm_mmap.c:690 #6 0xffffffff820f9372 at amd64_syscall+0x4e2 /usr/obj/usr/src/kern/subr_syscall.c:193 #7 0xffffffff8209ffab at fast_syscall_common+0xf8 /usr/obj/usr/src/amd64/amd64/exception.S:571 Uptime: 55s Automatic reboot in 15 seconds - press a key on the console to abort ``` -- You are receiving this mail because: You are the assignee for the bug.home | help
