The INSTALL_AS_USER option tells "install" to use the current
user name as the owner of the installed file. The "install"
command executed by the build is statically linked, so it does not
load nsswitch modules, such as nss_ldap.so, so it fails when
the user is only defined in such a database.
Fix it to use the current UID instead of user name. This works
for all users. I expect it is also slightly more efficient.

Extend the ino_t, dev_t, nlink_t types to 64-bit ints. Modify
struct dirent layout to add d_off, increase the size of d_fileno
to 64-bits, increase the size of d_namlen to 16-bits, and change
the required alignment. Increase struct statfs f_mntfromname[] and
f_mntonname[] array length MNAMELEN to 1024.
ABI breakage is mitigated by providing compatibility using versioned
symbols, ingenious use of the existing padding in structures, and
by employing other tricks. Unfortunately, not everything can be
fixed, especially outside the base system. For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.
Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.
Struct xvnode changed layout, no compat shims are provided.
For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful
than reporting 64-bit dev_t, for the sake of pstat.
Update note: strictly follow the instructions in UPDATING. Build
and install the new kernel with COMPAT_FREEBSD11 option enabled,
then reboot, and only then install new world.

ENA is a networking interface designed to make good use of modern CPU
features and system architectures.
The ENA device exposes a lightweight management interface with a
minimal set of memory mapped registers and extendable command set
through an Admin Queue.
The driver supports a range of ENA devices, is link-speed independent
(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
a negotiated and extendable feature set.
Some ENA devices support SR-IOV. This driver is used for both the
SR-IOV Physical Function (PF) and Virtual Function (VF) devices.
ENA devices enable high speed and low overhead network traffic
processing by providing multiple Tx/Rx queue pairs (the maximum number
is advertised by the device via the Admin Queue), a dedicated MSI-X
interrupt vector per Tx/Rx queue pair, and CPU cacheline optimized
data placement.
The ENA driver supports industry standard TCP/IP offload features such
as checksum offload and TCP transmit segmentation offload (TSO).
Receive-side scaling (RSS) is supported for multi-core scaling.
The ENA driver and its corresponding devices implement health
monitoring mechanisms such as watchdog, enabling the device and driver
to recover in a manner transparent to the application, as well as
debug logs.
Some of the ENA devices support a working mode called Low-latency
Queue (LLQ), which saves several more microseconds. This feature will
be implemented for driver in future releases.

The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.
Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms. The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.
Note that this driver is still under active development and testing and
may not yet be ready for production use. It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.
To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver. These can be done by setting the following
tunables before loading the cxgbe(4) driver:
hw.cxgbe.config_file=uwire
hw.cxgbe.cryptocaps_allowed=-1

This will help application developers simulate end of tape conditions.
To inject an error in sa0:
sysctl kern.cam.sa.0.inject_eom=1
This will return the next read or write request queued with 0 bytes
written. Any subsequent writes or reads will go along as usual.
This will also cause the early warning position flag to get set
for the next position query. So, 'mt status' will show the BPEW
(Beyond Programmable Early Warning) flag on the first query after
an error injection. After that, the position flags will be as they
are in the underlying tape drive.
Also, update the sa(4) man page to describe tape parameters,
which can be set via 'mt param'.
sys/cam/scsi/scsi_sa.c:
In saregister(), create the inject_eom sysctl variable.
In sastart(), check to see whether inject_eom is set. If
so, return the read or write with 0 bytes written to
indicate EOM. Set the set_pews_status flag so that we
fake PEWS status in the next position call for reads, and the
next 3 calls for writes. This allows the user to see the BPEW
flag one time via 'mt status'.
In sagetpos(), check the set_pews_status flag and fake
PEWS status and decrement the counter if it is set.
share/man/man4/sa.4:
Document the inject_eom sysctl variable.

After FreeBSD SVN revision 236814, the pass(4) driver changed from
only doing error recovery when the CAM_PASS_ERR_RECOVER flag was
set on a CCB to sometimes doing error recovery if the passed in
retry count was non-zero.
Error recovery would happen if two conditions were met:
1. The error recovery action was simply a retry. (Which is most
cases.)
2. The retry_count is non-zero. (Which happened a lot because of
cut-and-pasted code.)
This explains a bug I noticed in with camcontrol:
# camcontrol tur da34 -v
Unit is ready
# camcontrol reset da34
Reset of 1:172:0 was successful
At this point, there should be a Unit Attention:
# camcontrol tur da34 -v
Unit is ready
No Unit Attention.
Try it again:
# camcontrol reset da34
Reset of 1:172:0 was successful
Now set the retry_count to 0 for the TUR:
# camcontrol tur da34 -v -C 0
Unit is not ready
(pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00
(pass42:mps1:0:172:0): CAM status: SCSI Status Error
(pass42:mps1:0:172:0): SCSI status: Check Condition
(pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred)
(pass42:mps1:0:172:0): Field Replaceable Unit: 2
There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.
The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).
sys/cam/scsi/scsi_pass.c:
In passsendccb(), when calling cam_periph_runccb(), only
specify the error routine when CAM_PASS_ERR_RECOVER is set.
share/man/man4/pass.4:
Document that CAM_PASS_ERR_RECOVER is needed to enable
error recovery.
