tests: Avoid sleep when causing a write error
Cause a write error using a fifo and wait, rather than needing a sleep
to wait for something to terminate. This is faster and avoids a
potential test failure on a heavily loaded system.
Using /dev/full would be simpler, but it is not portable enough (it
tends not to be available in jails, even). Starting programs with stdout
not open or only open for read/execute/search may have unexpected side
effects.

diff: Correct fd 0 case on pipe
After git commit c8d40bf8ecc60cc15e3904410db62065ea681fdc, if fd 0 was
not open, it is left with CLOEXEC set and therefore fails. This is an
unlikely situation, but fixing it reduces the size of the code (by using
posix_spawn_file_actions_adddup2's special case if the two file
descriptor numbers are the same).
At the same time, check the error code from
posix_spawn_file_actions_adddup2.

ena: Budget rx descriptors, not packets
We had ENA_RX_BUDGET = 256 in order to allow up to 256 received
packets to be processed before we do other cleanups (handling tx
packets and, critically, refilling the rx buffer ring). Since the
ring holds 1024 buffers by default, this was fine for normal packets:
We refill the ring when it falls below 7/8 full, and even with a large
burst of incoming packets allowing it to fall by another 1/4 before we
consider refilling the ring still leaves it at 7/8 - 1/4 = 5/8 full.
With jumbos, the story is different: A 9k jumbo (as is used by default
within the EC2 network) consumes 3 descriptors, so a single rx cleanup
pass can consume 3/4 of the default-sized rx ring; if the rx buffer
ring wasn't completely full before a packet burst arrives, this puts
us perilously close to running out of rx buffers.
This precise failure mode has been observed on some EC2 instance types
within a Cluster Placement Group, resulting in the nominal 10 Gbps
single-flow throughput between instances dropping to ~100 Mbps as a

ena: Adjust ena_[rt]x_cleanup to return bool
The ena_[rt]x_cleanup functions are limited internally to a maximum
number of packets; this ensures that TX doesn't starve RX (or vice
versa) and also attempts to ensure that we get a chance to refill
the RX buffer ring before the device runs out of buffers and starts
dropping packets.
Historically these functions have returned the number of packets which
they processed which ena_cleanup compares to their respective budgets
to decide whether to reinvoke them. This is unnecessary complication;
since the precise number of packets processed is never used, adjust
the APIs of those functions to return a bool indicating if they want
to be reinvoked (aka if they hit their limits).
Since ena_tx_cleanup now only uses work_done if diagnostics are
enabled (ena_log_io macros to nothing otherwise) eliminate that
variable and pass its value (ENA_TX_BUDGET - budget) to ena_log_io
directly.

ena: Report RX overrun errors
Extract rx_overruns from the keep alive descriptor reported by
the device and expose it via sysctl hw stats.
RX overrun errors occur when a packet arrives but there are not
enough free buffers in the RX ring to receive it.

krpc: Get rid of KRPC_VNET macros
When the krpc was vnet'd, the VNET macros were hidden
behind macros that had the KRPC_ prefix on them.
This was done because, at the time, it was thought
that something other than vnet might be used for this.
That has not happened and probably will not happen,
so this patch replaces these obscuring macros with
the regular vnet ones.
There should be no semantics change caused by
this commit.

nfscl: Fix handling of gssd upcalls for the NFS client
Without this patch, all upcalls to the gssd daemon are
done in vnet0 (outside of any vnet jail). This does
not work well, because a user principal's credential
cache can be within the jail (/tmp/krb5cc_NNN in the
jail's namespace).
This patch modifies the client so that RPCs done
from within vnet jails does an upcall to a gssd
daemon running within the vnet jail. It required
that the cache of uid->credential shorthands in
the rpcsec_gss be vnet'd.
The situation is still less than ideal and sec=krb5[ip]
mounts that are visible within vnet jails is still
not something I would recommend, but it can work ok
with this patch.
