site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com i’ve a TCP and UDP filter both registering for IPv4 and IPv6. It’s that when try to unload I get to this situation. I looked at the protocol type of the socket it is 0, meaning unspecified !. Not sure what may cause such a thing. //Frame 1 39 440 while (filter) { 441 struct socket_filter *filter_next; 442 /* 443 * Warning: sflt_attach_private_locked 444 * will drop the lock 445 */ -> 446 sflt_attach_locked(so, filter, 0); 447 448 filter_next = TAILQ_NEXT(filter, sf_protosw_next); 449 if (filter_next) 450 sflt_retain_locked(filter_next); 451 452 /* 453 * Warning: filt_release_locked may remove 454 * the filter from the queue 455 */ 456 sflt_release_locked(filter); 457 filter = filter_next; 458 } 459 } //Frame 2 765 /* Attach socket filters for this protocol */ -> 766 sflt_initsock(so); * thread #3: tid = 0x0244, 0xffffff7f916e0fc0, name = '0xffffff801aa19dc8', queue = '0x0', stop reason = EXC_BAD_ACCESS (code=1, address=0x916e0fc0) frame #0: 0xffffff7f916e0fc0 * frame #1: 0xffffff800f9f3fad kernel`sflt_initsock(so=<unavailable>) + 125 at kpi_socketfilter.c:446 [opt] frame #2: 0xffffff800f9c9c84 kernel`socreate_internal(dom=<unavailable>, aso=<unavailable>, type=<unavailable>, proto=0, p=0xffffff801abdfe90, flags=0, ep=<unavailable>) + 708 at uipc_socket.c:766 [opt] frame #3: 0xffffff800f9db071 kernel`socket_common [inlined] socreate(dom=<unavailable>, aso=<unavailable>, type=<unavailable>, proto=<unavailable>) + 37 at uipc_socket.c:827 [opt] frame #4: 0xffffff800f9db04c kernel`socket_common(p=<unavailable>, domain=30, type=2, protocol=0, epid=105, retval=0xffffff801abb2040, delegate=<unavailable>) + 332 at uipc_syscalls.c:264 [opt] frame #5: 0xffffff800f9daee3 kernel`socket(p=<unavailable>, uap=<unavailable>, retval=<unavailable>) + 67 at uipc_syscalls.c:214 [opt] frame #6: 0xffffff800fa27066 kernel`unix_syscall(state=<unavailable>) + 550 at systemcalls.c:192 [opt] frame #7: 0xffffff800f4a3c38 kernel`hndl_unix_scall + 216 General Purpose Registers: rbx = 0x0000000000000000 <—— rbp = 0xffffff90a82f3e40 rsp = 0xffffff90a82f3e20 r12 = 0xffffff80237b0cf8 r13 = 0x0000000000000000 r14 = 0xffffff8024184868 r15 = 0xffffff8024184840 rip = 0xffffff800f9f3fad kernel`sflt_initsock + 125 at kpi_socketfilter.c:448 kernel`sflt_initsock: 0xffffff800f9f3f30 <+0>: pushq %rbp 0xffffff800f9f3f31 <+1>: movq %rsp, %rbp 0xffffff800f9f3f34 <+4>: pushq %r15 0xffffff800f9f3f36 <+6>: pushq %r14 0xffffff800f9f3f38 <+8>: pushq %r12 0xffffff800f9f3f3a <+10>: pushq %rbx 0xffffff800f9f3f3b <+11>: movq %rdi, %r15 0xffffff800f9f3f3e <+14>: movq 0x18(%r15), %rax 0xffffff800f9f3f42 <+18>: movq 0x18(%rax), %rbx 0xffffff800f9f3f46 <+22>: movq 0x31534b(%rip), %rdi 0xffffff800f9f3f4d <+29>: callq 0xffffff800f49f8c0 ; lck_rw_lock_shared 0xffffff800f9f3f52 <+34>: cmpq $0x0, 0x80(%rbx) 0xffffff800f9f3f5a <+42>: je 0xffffff800f9f400d ; <+221> at kpi_socketfilter.c:460 0xffffff800f9f3f60 <+48>: movq 0x315331(%rip), %rdi 0xffffff800f9f3f67 <+55>: callq 0xffffff800f49fae0 ; lck_rw_lock_shared_to_exclusive 0xffffff800f9f3f6c <+60>: testl %eax, %eax 0xffffff800f9f3f6e <+62>: jne 0xffffff800f9f3f7c ; <+76> at kpi_socketfilter.c:436 0xffffff800f9f3f70 <+64>: movq 0x315321(%rip), %rdi 0xffffff800f9f3f77 <+71>: callq 0xffffff800f49f9f0 ; lck_rw_lock_exclusive 0xffffff800f9f3f7c <+76>: movq 0x80(%rbx), %rbx 0xffffff800f9f3f83 <+83>: incl 0xf0(%rbx) 0xffffff800f9f3f89 <+89>: testq %rbx, %rbx 0xffffff800f9f3f8c <+92>: je 0xffffff800f9f400d ; <+221> at kpi_socketfilter.c:460 0xffffff800f9f3f92 <+98>: leaq 0x18dc43(%rip), %r14 ; ""lck_rw_unlock_exclusive(): lock held in mode: %d\n"@/Library/Caches/com.apple.xbs/Sources/xnu/xnu-3789.41.3/osfmk/i386/locks_i386.c:1236" 0xffffff800f9f3f99 <+105>: nopl (%rax) 0xffffff800f9f3fa0 <+112>: xorl %edx, %edx 0xffffff800f9f3fa2 <+114>: movq %r15, %rdi 0xffffff800f9f3fa5 <+117>: movq %rbx, %rsi 0xffffff800f9f3fa8 <+120>: callq 0xffffff800f9f3a10 ; sflt_attach_locked at kpi_socketfilter.c:296 -> 0xffffff800f9f3fad <+125>: movq (%rbx), %r12 0xffffff800f9f3fb0 <+128>: testq %r12, %r12 0xffffff800f9f3fb3 <+131>: je 0xffffff800f9f3f _______________________________________________ Do not post admin requests to the list.
