>Synopsis: lock order reversal when starting net/knot
>Category: kernel
>Environment:
System : OpenBSD 6.3
Details : OpenBSD 6.3-current (GENERIC.MP) #125: Wed Jul 11

[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
When I run knot (an authoritative name server daemon that uses
LMDB) the following entries appear in dmesg:
lock order reversal:
1st 0xffffff01ff732468 vmmaplk (&map->lock) @ /usr/src/sys/uvm/uvm_map.c:4433
2nd 0xffffff01fe312098 inode (&ip->i_lock) @
/usr/src/sys/ufs/ufs/ufs_vnops.c:1544
lock order "&ip->i_lock"(rrwlock) -> "&map->lock"(rwlock) first seen at:
#0 witness_checkorder+0x4c0
#1 _rw_enter+0x68
#2 vm_map_lock_ln+0xbc
#3 uvm_map+0x1a1
#4 km_alloc+0x16a
#5 pool_multi_alloc_ni+0xbb
#6 pool_p_alloc+0x56
#7 pool_do_get+0xe4
#8 pool_get+0xaf
#9 ufsdirhash_build+0x31e
#10 ufs_lookup+0x19d
#11 VOP_LOOKUP+0x4f
#12 vfs_lookup+0x27e
#13 namei+0x226
#14 start_init+0xb2
lock order "&map->lock"(rwlock) -> "&ip->i_lock"(rrwlock) first seen at:
#0 witness_checkorder+0x4c0
#1 _rw_enter+0x68
#2 _rrw_enter+0x3e
#3 VOP_LOCK+0x3d
#4 vn_lock+0x34
#5 uvn_io+0x1b8
#6 uvm_pager_put+0x109
#7 uvn_flush+0x424
#8 uvm_map_clean+0x3e7
#9 syscall+0x32a
#10 Xsyscall+0xef
fwiw this looks very similar to the lock order traces seen by Vijay
Sankar when testing an update to samba-4.8.3 (ports/net/samba):

>How-To-Repeat:
Start knot (at boot time or from a shell)
>Fix:
Unknown
