christos d8c52c37b1 use a different root vnode variable to appease the rump gods. 2017-04-11 21:15:57 +00:00
jmcneill 4d3af4e0f2 Now that FAT+FFS images include the BSD partition in the MBR partition 
table, install the disklabel after setting up MBR partitions. This moves
the disklabel to the BSD partition from the start of the disk, avoiding
a conflict with the ODROID-C1 bootloader.

roy 9ceca8afd6 Cast sizeof to socklen_t as pointed out by kre@ 2017-04-11 18:20:03 +00:00
jmcneill efb61fccf8 Improvements and fixes for FAT+FFS images: 
- Add a "NETBSD" volume label to the MSDOS file-system.
 - Explicitly initialize boot sector.
 - Correct an issue where the MSDOS file-system was larger than the
   partition table entry.
 - Add NetBSD partition to the MBR partition table.

roy 5135ab1948 Add RO_MSGFILTER socket option to PF_ROUTE to filter out 
un-wanted route(4) messages.

Inspired by the ROUTE_MSGFILTER equivalent in OpenBSD,
but with an API which allows the full range of potential message types.

riastradh 4de868a56e New diagnostic functions vn_locked, vn_anylocked. 
For use only within KASSERT.

vn_locked asserts exclusive lock, as most operations require.
vn_anylocked asserts exclusive or shared lock.

No effect unless VV_LOCKSWORK.  This will reduce the visual cost of
sprinkling lock ownership assertions throughout kern/vfs_*.

riastradh 666f39d910 Fix non-DIAGNOSTIC build by using vp outside KASSERT too. 2017-04-11 06:01:03 +00:00
riastradh aba083eab6 Sprinkle lock ownership assertions. 2017-04-11 05:48:04 +00:00
riastradh 74180a5176 Use a spin lock -- we take this in interrupt context. 
The nv_wait is a busy-wait, so holding a spin lock over it is OK.

Found, fixed, and tested by maya.  Cosmetically tweaked by me.
