With these two ioctls implemented in the nda driver, nvmecontrol now
works with nda just like it does with nvd. It eliminates the need to
jump through odd hoops to get this data.
Add the nvmeX device to the XPT_PATH_INQ nvme specific
information. while one could figure this out by looking up the
domain🚌slot:function, it's a lot easier to have the SIM set it
directly since the sim knows this.
which can cause a TCP client to use invalid or stale TCP sequence numbers for ACK packets.
Packets with old sequence numbers are ignored and not used to update the send window size.
This might cause the TCP session to hang indefinitely under some circumstances.

Otherwise, since the CV is not signalled until data is drained from the

A concurrent unlocked lookup can wire the page after

The NFS code had a bunch of Mac OS/X accessor functions named uio_XXX
left over from the port to Mac OS/X. Since that port is long forgotten,
replace the calls with the code generated by the FreeBSD macros for these

and I think makes the code more readable.
This patch should not result in any semantic change.
This largely reuses the TLS TOE support added in r330884. However,
this uses the KTLS framework in upstream OpenSSL rather than requiring
Chelsio-specific patches to OpenSSL. As with the existing TLS TOE
support, use of RX offload requires setting the tls_rx_ports sysctl.

Without this patch, sosend_generic() will try to use top->m_pkthdr.len,
assuming that the first mbuf has a pkthdr.
When a list of ext_pgs mbufs is passed in, the first mbuf is not a
pkthdr and cannot be post-r359919. As such, the value of top->m_pkthdr.len
is bogus (0 for my testing).
This patch fixes sosend_generic() to handle this case, calculating the
total length via m_length() for this case.
There is currently nothing that hands a list of ext_pgs mbufs to
sosend_generic(), but the nfs-over-tls kernel RPC code in
projects/nfs-over-tls will do that and was used to test this patch.

This was changed in the review process for the flags sysctl. The
reasons for the change are no longer valid as the code changed after
that. Cast the one place where it might make a difference (but I don't
think it does). This restores the ability to see flags for softc in
gdb.
- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
authentication algorithms and keys as well as the initial sequence
number.
- When reading from a socket using KTLS receive, applications must use
recvmsg(). Each successful call to recvmsg() will return a single
TLS record. A new TCP control message, TLS_GET_RECORD, will contain
the TLS record header of the decrypted record. The regular message
buffer passed to recvmsg() will receive the decrypted payload. This
is similar to the interface used by Linux's KTLS RX except that
Linux does not return the full TLS header in the control message.
- Add plumbing to the TOE KTLS interface to request either transmit
or receive KTLS sessions.
- When a socket is using receive KTLS, redirect reads from
soreceive_stream() into soreceive_generic().
- Note that this interface is currently only defined for TLS 1.1 and
1.2, though I believe we will be able to reuse the same interface
and structures for 1.3.
This patch is intended to solve a specific problem that iavf(4)
encounters, but what it does can be extended to solve other issues.
To summarize the iavf(4) issue, if the PF driver configures VLAN
anti-spoof, then the VF driver needs to make sure no untagged traffic is
sent if a VLAN is configured, and vice-versa. This can be an issue when
a VLAN is being registered or unregistered, e.g. when a packet may be on
the ring with a VLAN in it, but the VLANs are being unregistered. This
can cause that tagged packet to go out and cause an MDD event.
To fix this, include a new interface-dependent function that drivers can
implement named IFDI_NEEDS_RESTART(). Right now, this function is called
in iflib_vlan_unregister/register() to determine whether the interface
needs to be stopped and started when a VLAN is registered or
unregistered. The default return value of IFDI_NEEDS_RESTART() is true,
so this fixes the MDD problem that iavf(4) encounters, since the
interface rings are flushed during a stop/init.
A future change to iavf(4) will implement that function just in case the
default value changes, and to make it explicit that this interface reset
is required when a VLAN is added or removed.

Modify the write filter to return the amount of buffer space available
even if no readers are present. This matches the behaviour for sockets.
When reading from a pipe, only call pipeselwakeup() if some data was
actually read. This prevents the continuous re-triggering of a
EVFILT_READ event on EOF when in edge-triggered mode.
