-current XEN build fails with WITNESS off
Hi all, I am running Adrian's Xen image on a pygrub domU and am building the kernel targeted towards production use. With that in mind, commenting out the lines: #optionsWITNESS # Enable checks to detect deadlocks and cycles #optionsWITNESS_SKIPSPIN# Don't run witness on spinlocks for speed Yields the error: In file included from /usr/src/sys/dev/xen/netfront/netfront.c:33: /usr/src/sys/sys/sx.h:211:2: error: #error LOCK_DEBUG not defined, include sys/lock.h before sys/sx.h mkdep: compile failed This is reproducible, at the very least, between 20090520 and 20090606. A very simple fix is: diff netfront.c netfront.old.c 33d32 #include sys/lock.h Let me know if I am doing something stupidly wrong (as I've only been running FreeBSD since yesterday) or if you need any more information. Thanks, Edwin PS. If there is any interest, I can provide weekly or so kernel builds. My config file is aimed towards use in a production environment with jails use, and thus has debugging options off and pf/vlan/NULLFS/FDESCFS enabled. -- Error Log -- -- Kernel build for XENNEKO started on Sat Jun 6 20:55:49 EDT 2009 -- === XENNEKO mkdir -p /usr/obj/usr/src/sys -- stage 1: configuring the kernel -- cd /usr/src/sys/i386/conf; PATH=/usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj/usr/src/tmp/legacy/usr/games:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/bin:/usr/obj/usr/src/tmp/usr/games:/sbin:/bin:/usr/sbin:/usr/bin config -d /usr/obj/usr/src/sys/XENNEKO /usr/src/sys/i386/conf/XENNEKO Kernel build directory is /usr/obj/usr/src/sys/XENNEKO Don't forget to do ``make cleandepend make depend'' -- stage 2.1: cleaning up the object tree -- cd /usr/obj/usr/src/sys/XENNEKO; MAKEOBJDIRPREFIX=/usr/obj MACHINE_ARCH=i386 MACHINE=i386 CPUTYPE=pentiumpro GROFF_BIN_PATH=/usr/obj/usr/src/tmp/legacy/usr/bin GROFF_FONT_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/groff_font GROFF_TMAC_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/tmac _SHLIBDIRPREFIX=/usr/obj/usr/src/tmp VERSION=FreeBSD 8.0-CURRENT i386 800095 INSTALL=sh /usr/src/tools/install.sh PATH=/usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj/usr/src/tmp/legacy/usr/games:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/bin:/usr/obj/usr/src/tmp/usr/games:/sbin:/bin:/usr/sbin:/usr/bin NO_CTF=1 make KERNEL=kernel cleandir rm -f *.o *.so *.So *.ko *.s eddep errs kernel.debug kernel kernel.symbols linterrs makelinks tags vers.c vnode_if.c vnode_if.h vnode_if_newproto.h vnode_if_typedef.h eisa_if.c mmcbr_if.c mmcbus_if.c card_if.c power_if.c pci_if.c pcib_if.c g_part_if.c isa_if.c bus_if.c clock_if.c cpufreq_if.c device_if.c linker_if.c serdev_if.c xenbus_if.c acpi_if.c eisa_if.h mmcbr_if.h mmcbus_if.h card_if.h power_if.h pci_if.h pcib_if.h g_part_if.h isa_if.h bus_if.h clock_if.h cpufreq_if.h device_if.h linker_if.h serdev_if.h xenbus_if.h acpi_if.h pccarddevs.h rm -f .depend machine cd /usr/src/sys/modules; MAKEOBJDIRPREFIX=/usr/obj/usr/src/sys/XENNEKO/modules KMODDIR=/boot/kernel MODULES_OVERRIDE= DEBUG_FLAGS=-g MACHINE=i386 KERNBUILDDIR=/usr/obj/usr/src/sys/XENNEKO SYSDIR=/usr/src/sys make cleandir -- stage 2.2: rebuilding the object tree -- cd /usr/obj/usr/src/sys/XENNEKO; MAKEOBJDIRPREFIX=/usr/obj MACHINE_ARCH=i386 MACHINE=i386 CPUTYPE=pentiumpro GROFF_BIN_PATH=/usr/obj/usr/src/tmp/legacy/usr/bin GROFF_FONT_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/groff_font GROFF_TMAC_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/tmac _SHLIBDIRPREFIX=/usr/obj/usr/src/tmp VERSION=FreeBSD 8.0-CURRENT i386 800095 INSTALL=sh /usr/src/tools/install.sh PATH=/usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj/usr/src/tmp/legacy/usr/games:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/bin:/usr/obj/usr/src/tmp/usr/games:/sbin:/bin:/usr/sbin:/usr/bin NO_CTF=1 make KERNEL=kernel obj cd /usr/src/sys/modules; MAKEOBJDIRPREFIX=/usr/obj/usr/src/sys/XENNEKO/modules KMODDIR=/boot/kernel MODULES_OVERRIDE= DEBUG_FLAGS=-g MACHINE=i386 KERNBUILDDIR=/usr/obj/usr/src/sys/XENNEKO SYSDIR=/usr/src/sys make obj -- stage 2.3: build tools -- cd /usr/obj/usr/src/sys/XENNEKO; MAKESRCPATH=/usr/src/sys/dev/aic7xxx/aicasm make SSP_CFLAGS= -DNO_CPU_CFLAGS -DNO_CTF -f /usr/src/sys/dev/aic7xxx/aicasm/Makefile Warning: Object directory

Adrian Hello, Well it is consistently reproductible : each time I issue a cvsup command. The interesting point is that I can _download_ without any problem with ftp (that is why sysinstall works) but if I start a ftpd on my host I get (consistently) a similar crash : # Kernel page fault with the following non-sleepable locks held: exclusive sleep mutex xennetif_tx (network transmit lock) r = 0 (0xc39400a0) locked @ /home/adrian/work/freebsd/xen/svn/head/sys/dev/xen/netfront/netfront.c:1118 KDB: stack backtrace: X_db_sym_numargs(c0360308,c3524ab8,c0111ac5,c0383ef6,45e,...) at X_db_sym_numargs+0x146 kdb_backtrace(c0383ef6,45e,,c0511c8c,c3524af0,...) at kdb_backtrace+0x29 witness_display_spinlock(c036278d,c3524b04,4,1,0,...) at witness_display_spinlock+0x75 witness_warn(5,0,c038c634,c3524b60,c,...) at witness_warn+0x1fd trap(c3524b8c) at trap+0x13e alltraps(c39400a0,0,c0383ef6,45e,d2cc5800,...) at alltraps+0x1b xlvbd_add(c394,c3524cc8,c00c3814,c03d5d00,c3783638,...) at xlvbd_add+0x32d0 intr_event_execute_handlers(c37097ec,c3783600,c0358a72,4e9,c3783670,...) at intr_event_execute_handlers+0x125 intr_event_add_handler(c378a440,c3524d38,c03587a5,336,c37097ec,...) at intr_event_add_handler+0x41f fork_exit(c00afcd0,c378a440,c3524d38) at fork_exit+0xb8 fork_trampoline() at fork_trampoline+0x8 --- trap 0, eip = 0, esp = 0xc3524d70, ebp = 0 --- Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x2 fault code = supervisor read, page not present instruction pointer = 0x21:0xc0300ad9 stack pointer = 0x29:0xc3524bcc frame pointer = 0x29:0xc3524bfc code segment= base 0x0, limit 0xf9800, type 0x1b = DPL 1, pres 1, def32 1, gran 1 processor eflags= interrupt enabled, resume, IOPL = 0 current process = 12 (irq134: xn) [thread pid 12 tid 100023 ] Stopped at xlvbd_add+0x2039: cmpl$0,0(%edi) db bt Tracing pid 12 tid 100023 td 0xc3784000 xlvbd_add(c39400a0,0,c0383ef6,45e,d2cc5800,...) at xlvbd_add+0x2039 xlvbd_add(c394,c3524cc8,c00c3814,c03d5d00,c3783638,...) at xlvbd_add+0x32d0 intr_event_execute_handlers(c37097ec,c3783600,c0358a72,4e9,c3783670,...) at intr_event_execute_handlers+0x125 intr_event_add_handler(c378a440,c3524d38,c03587a5,336,c37097ec,...) at intr_event_add_handler+0x41f fork_exit(c00afcd0,c378a440,c3524d38) at fork_exit+0xb8 fork_trampoline() at fork_trampoline+0x8 --- trap 0, eip = 0, esp = 0xc3524d70, ebp = 0 --- db so the problem seems to come more from upload traffic than download ?
