Several minor questions (12.0-amd64)
Hello, I have several brief questions on issues I'm slightly stuck on: 1. For buildworld, my /etc/src.conf uses default CROSS_COMPILER, CLANG_BOOTSTRAP, CLANG_FULL for amd64, but I would like clang to xbuild only for target i386 as I do not need the others (like Target/arm). Is there a knob for this? 2. Is there a way to read a list of modules inside an unloaded kernel? Sort of "kldstat -v" for a non-loaded kernel? Reading the kernel manifest (INCLUDE_CONFIG_FILE setting) is not what I need. 3. Under one scenario, I'm getting a kernel panic but I cannot dump because busybox states "no dumpdev specified" which means rc.conf (where I have dumpdev set) has not been read yet. How can I pass dumpdev wile in busybox command line so that ">dump" does its job? 4. Getting several of these lock order reversals. Kernel is drm-next but Generic from Head gives the same messages. Not urgent, just FYI. lock order reversal: 1st 0xf80064915040 filedesc structure (filedesc structure) @ /asp/git/srcdrm/sys/kern/kern_descrip.c:1234 2nd 0xf8002e9f0d50 ufs (ufs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:5022 stack backtrace: #0 0x804d3180 at witness_debugger+0x70 #1 0x804d3073 at witness_checkorder+0xe23 #2 0x8044aa35 at __lockmgr_args+0x875 #3 0x814d09e5 at ffs_lock+0xa5 #4 0x80717840 at VOP_LOCK1_APV+0xe0 #5 0x8054847a at _vn_lock+0x6a #6 0x8042c9c8 at knlist_remove_kq+0x88 #7 0x8053f358 at filt_vfsdetach+0x28 #8 0x8042d4f1 at knote_fdclose+0x171 #9 0x804206b5 at closefp+0x65 #10 0x806afe9a at amd64_syscall+0x57a #11 0x80692dcb at Xfast_syscall+0xfb lock order reversal: 1st 0xf80064915040 filedesc structure (filedesc structure) @ /asp/git/srcdrm/sys/kern/kern_descrip.c:1234 2nd 0xf8004b4d3d50 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:5022 stack backtrace: #0 0x804d3180 at witness_debugger+0x70 #1 0x804d3073 at witness_checkorder+0xe23 #2 0x8044a0fe at lockmgr_lock_fast_path+0x1ce #3 0x80717840 at VOP_LOCK1_APV+0xe0 #4 0x8054847a at _vn_lock+0x6a #5 0x8042c9c8 at knlist_remove_kq+0x88 #6 0x8053f358 at filt_vfsdetach+0x28 #7 0x8042d4f1 at knote_fdclose+0x171 #8 0x804206b5 at closefp+0x65 #9 0x806afe9a at amd64_syscall+0x57a #10 0x80692dcb at Xfast_syscall+0xfb lock order reversal: 1st 0xf801aec715f0 syncer (syncer) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2152 2nd 0xf8004bc3e068 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2602 stack backtrace: #0 0x804d3180 at witness_debugger+0x70 #1 0x804d3073 at witness_checkorder+0xe23 #2 0x8044a0fe at lockmgr_lock_fast_path+0x1ce #3 0x80717840 at VOP_LOCK1_APV+0xe0 #4 0x8054847a at _vn_lock+0x6a #5 0x80538892 at vget+0x82 #6 0x8053a936 at vfs_msync+0xa6 #7 0x8053ef96 at sync_fsync+0xc6 #8 0x80716890 at VOP_FSYNC_APV+0xe0 #9 0x8053d2fc at sched_sync+0x36c #10 0x80436f44 at fork_exit+0x84 #11 0x8069301e at fork_trampoline+0xe lock order reversal: 1st 0xf80039590d50 zfs (zfs) @ /asp/git/srcdrm/sys/kern/vfs_mount.c:855 2nd 0xf8001a4489a0 devfs (devfs) @ /asp/git/srcdrm/sys/kern/vfs_subr.c:2602 stack backtrace: #0 0x804d3180 at witness_debugger+0x70 #1 0x804d3073 at witness_checkorder+0xe23 #2 0x8044a0fe at lo ckmgr_lock_fast_path+0x1ce #3 0x80717840 at VOP_LOCK1_APV+0xe0 #4 0x8054847a at _vn_lock+0x6a #5 0x80538892 at vget+0x82 #6 0x80395b2d at devfs_allocv+0xcd #7 0x80395643 at devfs_root+0x43 #8 0x8052f66f at vfs_donmount+0x118f #9 0x8052e4b2 at sys_nmount+0x72 #10 0x806afe9a at amd64_syscall+0x57a #11 0x80692dcb at Xfast_syscall+0xfb ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
default uid/gid for nfsuserd.c
Hi, I just added GID_NOGROUP to sys/conf.h and fixed the initial values for nobody/nogroup in the kernel. However, UID_NOBODY and GID_NOGROUP are in the _KERNEL section of sys/conf.h, so they aren't visible in userland. So, how to I set the initial uid/gid values for nfsuserd.c? (nfsuserd.c looks for entries in the password and group databases, so these defaults only get used if it doesn't find an entry in the database.) I don't mind using the hardcoded values, but is there a better way? (Moving the #define's out of the _KERNEL section maybe?) rick ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

This is what the code snippet in the file looks like when error is encountered:
vagrant@freebsd12current:~/src/usr.bin/diff % awk 'NR>=1080&&NR<=1090' diffreg.c
change(char *file1, FILE *f1, char *file2, FILE *f2, int a, int b, int c, int d,
int *pflags)
{
static size_t max_context = 64;
long curpos;
int i, nc;
const char *walk;
restart:
if ((diff_format != D_IFDEF || diff_format == D_GFORMAT) &&
a > b && c > d)
The following snippet removes the error during build:
vagrant@freebsd12current:~/src/usr.bin/diff % awk 'NR>=1080&&NR<=1091' diffreg.c
change(char *file1, FILE *f1, char *file2, FILE *f2, int a, int b, int c, int d,
int *pflags)
{
static size_t max_context = 64;
long curpos;
int i, nc;
int 0;
const char *walk;
restart:
if ((diff_format != D_IFDEF || diff_format == D_GFORMAT) &&
a > b && c > d)

I reverted the commit that hardcoded them, since I agree that wasn't a good thing to do. I didn't realize that "nobody" was already defined in sys/conf.h and I can use that. I didn't know nobody was already there either. They are only used by zfs, while the others were originally only sed for devices. There is no definition for "nogroup" in sys/conf.h. Would it be ok to add #define GID_NOGROUP 65533 to syy/conf.h? (I know bde@ doesn't like expressing this as 65533, but that is what it is in /etc/group.) sys/conf.h already has GID_NOBODY but it is subtly different from GID_NOGROUP. It seems to be a bug that zfs uses nobody's gid instead of the gid nogroup which is used by no body.

The default uid/gid in nfsuserd.c needs to be fixed too, although they only get used if there isn't an entry for nobody/nogroup in the password/group database. ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
