78c235c99f The in6_setscope() function determines the scope zone id of an address
and embeds it into address. Inside the kernel we keep addresses with
embedded zone id only for two scopes: link-local and interface-local.

For other scopes this function is nop in most cases. To reduce an
overhead of locking, first check that address is capable for embedding.
Also, handle the loopback address before acquire the lock.

e1c562d83a Add support for triggering spectral scan upon a channel reset/change.
This is intended to support reporting FFT results during active channel
scans, for users who would like to fiddle around with writing applications
that do both FFT visualisation _and_ AP scanning.

* add a new ioctl to enable/trigger spectral scan at channel change/reset;
* set do_spectral consistently if it's enabled, so a channel set/reset
  will carry forth the correct PHY error configuration so frames
  are actually received;
* for NICs that don't do spectral scan, don't bother checking the
  spectral scan state on channel change/reset.

Tested:

* AR9280 - STA and scanning;
* AR5416 - STA, ensured that the SS code doesn't panic

fc1ae0bc42 Bring in some userboot changes from the bhyve branch to reduce diffs.
r238966
  Bump up the heap size to 1MB. With a few kernel modules, libstand
  zalloc and userboot seem to want to use ~600KB of heap space, which
  results in a segfault when malloc fails in bhyveload.

r241180
  Clarify comment about default number of FICL dictionary cells.

r241153
  Allow the number of FICL dictionary cells to be overridden.
  Loading a 7.3 ISO with userboot/amd64 takes up 10035 cells,
  overflowing the long-standing default of 10000.

  Bump userboot's value up to 15000 cells.

fdde618d1d Fix cache-related issue with pmap for ARMv6/ARMv7:
- Missing PTE_SYNC in pmap_kremove caused memory corruption
    in userland applications
- Fix lack of cache flushes when using special PTEs for zeroing or
    copying pages. If there are dirty lines for destination memory
    and page later remapped as a non-cached region actual content
    might be overwritten by these dirty lines when cache eviction
    happens as a result of applying cache eviction policy or because
    of wbinv_all call.
- icache sync for new mapping for userland applications.

43e35466de Revert r244549.
This change was originally intended to account for test kthreads under
the nvmecontrol process, but jhb indicated it may not be safe to
associate kthreads with userland processes and this could have
unintended consequences.

I did not observe any problems with this change, but my testing didn't
exhaust the kinds of corner cases that could cause problems.  It is not
that important to account for these test threads under nvmecontrol, so I
am just reverting this change for now.

On a related note, the part of this patch for <= 7.x fails compilation
so reverting this fixes that too.

4fd5efe79e tmpfs: Replace directory entry linked list with RB-Tree.
Use file name hash as a tree key, handle duplicate keys.  Both VOP_LOOKUP
and VOP_READDIR operations utilize same tree for search.  Directory
entry offset (cookie) is either file name hash or incremental id in case
of hash collisions (duplicate-cookies).  Keep sorted per directory list
of duplicate-cookie entries to facilitate cookie number allocation.

Don't fail if previous VOP_READDIR() offset is no longer valid, start
with next dirent instead.  Other file system handle it similarly.

Workaround race prone tn_readdir_last[pn] fields update.

Add tmpfs_dir_destroy() to free all dirents.

Set NFS cookies in tmpfs_dir_getdents(). Return EJUSTRETURN from
tmpfs_dir_getdents() instead of hard coded -1.

Mark directory traversal routines static as they are no longer
used outside of tmpfs_subr.c

7ea3aada55 Handle ps-poll data frame if_transmit() failure.
If the data frame transmission failures, it may have a node reference
that needs cleaning up.

If the frame is marked as M_ENCAP then it should treat recvif as a node
reference and clear it.

Now - since the mbuf has been freed by calling if_transmit() (even on
failure), the mbuf has to be treated as invalid.  Hence why the ifp is
used.

17b08c4368 Handle HWMP if_transmit() failure gracefully.
If if_transmit() fails, the node ref may need freeing.

This is based on the same logic used by the ageq, which the mesh code
(re) uses for frames which need to be staged before transmitting.
It also does the same thing - if M_ENCAP is set on the mbuf, it treats
the recvif pointer as a node reference and derefs it.

9cf4c952ca Add the "nocache" nullfs mount option, which disables the caching of
the free nullfs vnodes, switching nullfs behaviour to pre-r240285.
The option is mostly intended as the last-resort when higher pressure
on the vnode cache due to doubling of the vnode counts is not
desirable.

Note that disabling the cache costs more than 2x wall time in the
metadata-hungry scenarious.  The default is "cache".
