https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245414 Bug ID: 245414 Summary: panic: softdep_setup_blkfree: not free Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sigsys@gmail.com I'm getting reproducible panics on up-to-date -CURRENT (r359682) whenever a process coredumps on a UFS partition. I tried to disable TRIM and it doesn't prevent the panic. On a VM with a single UFS partition, the panic occurs a second or so after a coredump. Sending CTRL+\ to any process triggers it every time so far. On another non-VM system I've tested on it takes a few times before it panics. <6>[46] pid 4472 (cat), jid 0, uid 1001: exited on signal 3 (core dumped) [202] WARNING: /mnt: TRIM flag on fs but disk does not support TRIM <6>[237] pid 23049 (cat), jid 0, uid 1001: exited on signal 3 (core dumped) <6>[326] pid 26313 (cat), jid 0, uid 1001: exited on signal 3 (core dumped) <6>[327] pid 26399 (cat), jid 0, uid 1001: exited on signal 3 (core dumped) <6>[328] pid 26504 (cat), jid 0, uid 1001: exited on signal 3 (core dumped) [329] panic: softdep_setup_blkfree: not free [329] cpuid = 2 [329] time = 1586221947 [329] KDB: stack backtrace: [329] db_trace_self_wrapper() at db_trace_self_wrapper+0x2c/frame 0xfffffe00ff8a6830 [329] vpanic() at vpanic+0x186/frame 0xfffffe00ff8a6880 [329] panic() at panic+0x43/frame 0xfffffe00ff8a68e0 [329] softdep_setup_blkfree() at softdep_setup_blkfree+0x292/frame 0xfffffe00ff8a6940 [329] ffs_blkfree_cg() at ffs_blkfree_cg+0x421/frame 0xfffffe00ff8a69f0 [329] ffs_blkfree() at ffs_blkfree+0xa4/frame 0xfffffe00ff8a6a50 [329] handle_workitem_freefrag() at handle_workitem_freefrag+0xbf/frame 0xfffffe00ff8a6aa0 [329] process_worklist_item() at process_worklist_item+0x272/frame 0xfffffe00ff8a6b40 [329] softdep_process_worklist() at softdep_process_worklist+0xc6/frame 0xfffffe00ff8a6b80 [329] softdep_flush() at softdep_flush+0xef/frame 0xfffffe00ff8a6bb0 [329] fork_exit() at fork_exit+0x7f/frame 0xfffffe00ff8a6bf0 [329] fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe00ff8a6bf0 [329] --- trap 0, rip = 0, rsp = 0, rbp = 0 --- [329] KDB: enter: panic Unread portion of the kernel message buffer: panic: softdep_setup_blkfree: not free cpuid = 5 time = 1586219503 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe003c7d3910 vpanic() at vpanic+0x182/frame 0xfffffe003c7d3960 panic() at panic+0x43/frame 0xfffffe003c7d39c0 softdep_setup_blkfree() at softdep_setup_blkfree+0x282/frame 0xfffffe003c7d3a20 ffs_blkfree_cg() at ffs_blkfree_cg+0x440/frame 0xfffffe003c7d3ac0 ffs_blkfree_trim_task() at ffs_blkfree_trim_task+0x54/frame 0xfffffe003c7d3b00 taskqueue_run_locked() at taskqueue_run_locked+0xaa/frame 0xfffffe003c7d3b80 taskqueue_thread_loop() at taskqueue_thread_loop+0x94/frame 0xfffffe003c7d3bb0 fork_exit() at fork_exit+0x80/frame 0xfffffe003c7d3bf0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe003c7d3bf0 --- trap 0, rip = 0, rsp = 0, rbp = 0 --- KDB: enter: panic __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:55 55 __asm("movq %%gs:%P1,%0" : "=r" (td) : "n" (offsetof(struct pcpu, (kgdb) #0 __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:55 #1 doadump (textdump=0) at /usr/src/sys/kern/kern_shutdown.c:394 #2 0xffffffff8049b43a in db_dump (dummy=<optimized out>, dummy2=<unavailable>, dummy3=<unavailable>, dummy4=<unavailable>) at /usr/src/sys/ddb/db_command.c:575 #3 0xffffffff8049b1fc in db_command (last_cmdp=<optimized out>, cmd_table=<optimized out>, dopager=1) at /usr/src/sys/ddb/db_command.c:482 #4 0xffffffff8049af6d in db_command_loop () at /usr/src/sys/ddb/db_command.c:535 #5 0xffffffff8049e168 in db_trap (type=<optimized out>, code=<optimized out>) at /usr/src/sys/ddb/db_main.c:253 #6 0xffffffff80c07dd4 in kdb_trap (type=3, code=0, tf=<optimized out>) at /usr/src/sys/kern/subr_kdb.c:699 #7 0xffffffff8105cc08 in trap (frame=0xfffffe003c7d3840) at /usr/src/sys/amd64/amd64/trap.c:578 #8 <signal handler called> #9 kdb_enter (why=0xffffffff811eb48a "panic", msg=<optimized out>) at /usr/src/sys/kern/subr_kdb.c:486 #10 0xffffffff80bbd8ae in vpanic (fmt=<optimized out>, ap=<optimized out>) at /usr/src/sys/kern/kern_shutdown.c:902 #11 0xffffffff80bbd643 in panic ( fmt=0xffffffff81c7c198 <cnputs_mtx> "\340\367\032\201\377\377\377\377") at /usr/src/sys/kern/kern_shutdown.c:839 #12 0xffffffff80ec9882 in softdep_setup_blkfree (mp=0xfffffe0034596100, bp=<optimized out>, blkno=7563456, frags=1, wkhd=0xfffff80004916b28) at /usr/src/sys/ufs/ffs/ffs_softdep.c:10917 #13 0xffffffff80eaa950 in ffs_blkfree_cg (ump=<optimized out>, fs=0xfffffe0034599000, devvp=0x12, bno=<optimized out>, size=<optimized out>, inum=<optimized out>, dephd=0xfffff80004916b28) at /usr/src/sys/ufs/ffs/ffs_alloc.c:2335 #14 0xffffffff80eabbd4 in ffs_blkfree_trim_task (ctx=0xfffff800048dcb00, pending=<optimized out>) at /usr/src/sys/ufs/ffs/ffs_alloc.c:2420 #15 0xffffffff80c1bffa in taskqueue_run_locked (queue=0xfffff800032e1500) at /usr/src/sys/kern/subr_taskqueue.c:476 #16 0xffffffff80c1d084 in taskqueue_thread_loop (arg=<optimized out>) at /usr/src/sys/kern/subr_taskqueue.c:793 #17 0xffffffff80b7b440 in fork_exit ( callout=0xffffffff80c1cff0 <taskqueue_thread_loop>, arg=0xfffff800032f5560, frame=0xfffffe003c7d3c00) at /usr/src/sys/kern/kern_fork.c:1051 #18 <signal handler called> -- You are receiving this mail because: You are the assignee for the bug.help
