nfsv4 client: do the BindConnectionToSession as required
During a recent testing event, it was reported that the NFSv4.1/4.2
server erroneously bound the back channel to a new TCP connection.
RFC5661 specifies that the fore channel is implicitly bound to a
new TCP connection when an RPC with Sequence (almost any of them)
is done on it. For the back channel to be bound to the new TCP
connection, an explicit BindConnectionToSession must be done as
the first RPC on the new connection.
Since new TCP connections are created by the "reconnect" layer
(sys/rpc/clnt_rc.c) of the krpc, this patch adds an optional
upcall done by the krpc whenever a new connection is created.
The patch also adds the specific upcall function that does a
BindConnectionToSession and configures the krpc to call it
when required.
This is necessary for correct interoperability with NFSv4.1/NFSv4.2
servers when the nfscbd daemon is running.
If doing NFSv4.1/NFSv4.2 mounts without this patch, it is
recommended that the nfscbd daemon not be running and that
the "pnfs" mount option not be specified.
truncate(1) is not case-sensitive with regard to setting the size
of a file. makefs(8), however, does not honor upper-case values.
Update release-specific files and the release(7) manual page to
reflect this.
Modular fib lookup framework features logic that allows
route update batching for the algorithms that cannot easily
apply the routing change without rebuilding. As a result,
dataplane lookups may return old data until the the sync
takes place. With the default sync timeout of 50ms, it is
possible that new binary like ping(8) executed exactly after
route(8) will still use the old fib data.
To address some aspects of the problem, framework executes
all rtable changes without RTF_GATEWAY synchronously.
To fix the aforementioned problem, this diff extends sync
execution for all RTF_STATIC routes (e.g. ones maintained by
route(8).
This fixes a bunch of tests in the networking space.
Currently, PCB caching mechanism relies on the rib generation
counter (rnh_gen) to invalidate cached nhops/LLE entries.
With certain fib algorithms, it is now possible that the
datapath lookup state applies RIB changes with some delay.
In that scenario, PCB cache will invalidate on the RIB change,
but the new lookup may result in the same nexthop being returned.
When fib algo finally gets in sync with the RIB changes, PCB cache
will not receive any notification and will end up caching the stale data.
To fix this, introduce additional counter, rnh_gen_rib, which is used
only when FIB_ALGO is enabled.
This counter is incremented by the control plane. Each time when fib algo
synchronises with the RIB, it updates rnh_gen to the current rnh_gen_rib value.
Initial fib algo implementation was build on a very simple set of
principles w.r.t updates:
1) algorithm is ether able to apply the change synchronously (DIR24-8)
or requires full rebuild (bsearch, lradix).
2) framework falls back to rebuild on every error (memory allocation,
nhg limit, other internal algo errors, etc).
This changes brings the new "intermediate" concept - batched updates.
Algotirhm can indicate that the particular update has to be handled in
batched fashion (FLM_BATCH).
The framework will write this update and other updates to the temporary
buffer instead of pushing them to the algo callback.
Depending on the update rate, the framework will batch 50..1024 ms of updates
and submit them to a different algo callback.
This functionality is handy for the slow-to-rebuild algorithms like DXR.
The intent is to better handle time intervals with large amount of RIB
updates (e.g. BGP peer going up or down), while still keeping low sync
delay for the rest scenarios.
The implementation is the following: updates are bucketed into the
buckets of size 50ms. If the number of updates within a current bucket
exceeds the threshold of 500 routes/sec (e.g. 10 updates per bucket
interval), the update is delayed for another 50ms. This can be repeated
until the maximum update delay (1 sec) is reached.
inp_lookup_mcast_ifp() is static and is only used in the inp_join_group().
The latter function is also static, and is only used in the inp_setmoptions(),
which relies on inp being non-NULL.
As a result, in the current code, inp_lookup_mcast_ifp() is always called
with non-NULL inp. Eliminate unused RT_DEFAULT_FIB condition and always
use inp fib instead.

Use makefs(8) in release VM-image generation instead of md(4) and newfs.

simplifies the script (no need to copy files to a fresh image at the end),

As a result of the last, this patch also adds support for generation of
powerpc64 and powerpc64le VM images.
No other changes to the output. Tested and working for both amd64 and

Allocate extra inodes in makefs when leaving free space in UFS images.
By default, makefs(8) has very few spare inodes in its output images,
which is fine for static filesystems, but not so great for VM images
where many more files will be added. Make makefs(8) use the same
default settings as newfs(8) when creating images with free space --
there isn't much point to leaving free space on the image if you
can't put files there. If no free space is requested, use current
behavior of a minimal number of available inodes.

nfsd: fix replies from session cache for multiple retries
Recent testing of network partitioning a FreeBSD NFSv4.1

Commit 05a39c2c1c18 fixed replying with the cached reply in

will fail for a subsequent retry of the RPC.
A subsequent retry would be an extremely rare event,
but this patch fixes this, so long as m_copym(..M_NOWAIT)

This fix affects the exceedingly rare case where a NFSv4
client retries a non-idempotent RPC, such as a lock
operation, multiple times. Note that retries only occur
after the client has needed to create a new TCP connection,
with a new TCP connection for each retry.
