the code auto-generated for *.m - kobj_lookup_method(9) is useful;
for example in back-ends or base class device drivers in order to
determine whether a default method has been overridden. Thus, allow
for the kobj_method_t pointer argument - used by KOBJOPLOOKUP in
order to update the cache entry - of kobj_lookup_method(9), to be
NULL. Actually, that pointer is redundant as it's just set to the
same kobj_method_t that the kobj_lookup_method(9) function returns
in the first place, but probably it serves to reduce the number of
instructions generated for KOBJOPLOOKUP.
- For the same reason, move updating kobj_lookup_{hits,misses} (if
KOBJ_STATS is defined) from kobj_lookup_method(9) to KOBJOPLOOKUP.
As a side-effect, this gets rid of the convoluted approach of always
incrementing kobj_lookup_hits in KOBJOPLOOKUP and then in case of
a cache miss, decrementing it in kobj_lookup_method(9) again.

lease file.
Some routers set very large values for rebind time (Netgear) and these
are erroneously reported as negative in the leasefile. This was due to a
wrong printf format specification of %ld for an unsigned long on 32-bit
platforms.
They would overflow a signed 32-bit time_t on 32 bit architectures. This
was taken care of, but a compiler optimisation makes this behave
erratically. This could be resolved by adding a -fwrapv flag, but
instead we can check the value before adding the current timestamp to
it.
In the lease file values are still wrong though:

When running the vnet init code (pf_load_vnet()) we used to iterate over
all vnets, marking them as unhooked.
This is incorrect and leads to panics if pf is unloaded, as the unload
code does not unregister the pfil hooks (because the vnet is marked as
unhooked).
There's no need or reason to touch other vnets during initialisation.
Their pf_load_vnet() function will be triggered, which handles all
required initialisation.

When sosend() replies ERESTART in the client side krpc, it indicates that
the RPC message hasn't yet been sent and that the send queue is full or
locked while a signal is posted for the process.
Without this patch, this would result in a RPC_CANTSEND reply from
clnt_vc_call(), which would cause clnt_reconnect_call() to create a new
TCP transport connection. For most NFS servers, this wasn't a serious problem,
although it did imply retries of outstanding RPCs, which could possibly
have missed the DRC.
For an NFSv4.1 mount to AmazonEFS, this caused a serious problem, since
AmazonEFS often didn't retain the NFSv4.1 session and would reply with
NFS4ERR_BAD_SESSION. This implies to the client a crash/reboot which
requires open/lock state recovery.
Three options were considered to fix this:
- Return the ERESTART all the way up to the system call boundary and then
have the system call redone. This is fraught with risk, due to convoluted
code paths, asynchronous I/O RPCs etc. cperciva@ worked on this, but it
is still a work in prgress and may not be feasible.
- Set SB_NOINTR for the socket buffer. This fixes the problem, but makes
the sosend() completely non interruptible, which kib@ considered
inappropriate. It also would break forced dismount when a thread
was blocked in sosend().
- Modify the retry loop in clnt_vc_call(), so that it loops for this case
for up to 15sec. Testing showed that the sosend() usually succeeded by
the 2nd retry. The extreme case observed was 111 loop iterations, or
about 100msec of delay.
This third alternative is what is implemented in this patch, since the
change is:
- localized
- straightforward
- forced dismount is not broken by it.
This patch has been tested by cperciva@ extensively against AmazonEFS.

Ensure showbase does not overflow do_put buffers
Summary:
In https://bugs.freebsd.org/207918, Daniel McRobb describes how using
std::showbase with ostreams can cause truncation of unsigned long long
when output format is octal. In fact, this can even happen with
unsigned int and unsigned long.
To ensure this does not happen, add one additional character to the
do_put buffers if std::showbase is on. Also add a test case.

The current read from network is working from up to down - we have some
protocol needing the data from the network, so we build the buffer space
for that protocol, add the extra space for headers and pass this buffer
down to be filled by nif get call in hope, we have guessed the incoming
packet size right. Amazingly enough this approach mostly does work, but
not always...
So, this update does work from down to up - we allocate buffer (based
on MTU or frame size info), fill it up, and pass on for upper layers.
The obvious problem is that when we should free the buffer - if at all.
In the current implementation the upper layer will free the packet on error
or when the packet is no longer needed.
While working on the issue, the additional issue did pop up - the bios
implementation does not have generic get/put interface but is using pxe
udpsend/udpreceive instead. So the udp calls are gone and undi interface
is implemented instead. Which in turn means slight other changes as we
do not need to have duplicated pxe implementation and can just use dev_net.
To align packet content, the actual read from nic is using shifted buffer by
ETHER_ALIGN (2).
