It fails out eventually, but on a system where DNS lookup is broken you

The significant changes and bugs fixed here are:
1. Fixed a bug in the progress display code:
When the user's filename is too big, or his terminal width is too
small, the progress code could wind up using a negative number for
the length of the "stars" that it uses to indicate progress.
This negative value was assigned to an unsigned variable, resulting
in a very large positive value.
The result is that we wound up writing garbage from memory to the
user's terminal.
With an 80 column terminal, a file name length of more than 35
characters would generate this problem.
To address this, we now set a minimum progress bar length, and
truncate the user's file name as needed.
This has been tested with large filenames and small terminals, and
at least produces reasonable results. If the terminal is too
narrow, the progress display takes up an additional line with each
update, but this is more user friendly than writing garbage to the
tty.
2. SATA drives connected via a SATA controller didn't have SCSI Inquiry
data populated in struct cam_device. This meant that the code in
fw_get_vendor() in fwdownload.c would try to match a zero-length
vendor ID, and so return the first entry in the vendor table. (Which
used to be HITACHI.) Fixed by grabbing identify data, passing the
identify buffer into fw_get_vendor(), and matching against the model
name.
3. SATA drives connected via a SAS controller do have Inquiry data
populated. The table included a couple of entries -- "ATA ST" and
"ATA HDS", intended to handle Seagate and Hitachi SATA drives attached
via a SAS controller. SCSI to ATA translation layers use a vendor
ID of "ATA" (which is standard), and then the model name from the ATA
identify data as the SCSI product name when they are returning data on
SATA disks. The cam_strmatch code will match the first part of the
string (because the length it is given is the length of the vendor,
"ATA"), and return 0 (i.e. a match). So all SATA drives attached to
a SAS controller would be programmed using the Seagate method
(WRITE BUFFER mode 7) of SCSI firmware downloading.
4. Issue #2 above covered up a bug in fw_download_img() -- if the
maximum packet size in the vendor table was 0, it tried to default
to a packet size of 32K. But then it didn't actually succeed in
doing that, because it set the packet size to the value that was
in the vendor table (0). Now that we actually have ATA attached
drives fall use the VENDOR_ATA case, we need a reasonable default
packet size. So this is fixed to properly set the default packet size.
5. Add support for downloading firmware to IBM LTO drives, and add a
firmware file validation method to make sure that the firmware
file matches the drive type. IBM tape drives include a Load ID and
RU name in their vendor-specific VPD page 0x3. Those should match
the IDs in the header of the firmware file to insure that the
proper firmware file is loaded.
6. This also adds a new -q option to the camcontrol fwdownload
subcommand to suppress informational output. When -q is used in
combination with -y, the firmware upgrade will happen without
prompting and without output except if an error condition occurs.
7. Re-add support for printing out SCSI inquiry information when
asking the user to confirm that they want to download firmware, and
add printing of ATA Identify data if it is a SATA disk. This was
removed in r237281 when support for flashing ATA disks was added.
8. Add a new camcontrol(8) "opcodes" subcommand, and use the
underlying code to get recommended timeout values for drive
firmware downloads.
Many SCSI devices support the REPORT SUPPORTED OPERATION CODES
command, and some support the optional timeout descriptor that
specifies nominal and recommended timeouts for the commands
supported by the device.
The new camcontrol opcodes subcommand allows displaying all
opcodes supported by a drive, information about which fields
in a SCSI CDB are actually used by a given SCSI device, and the
nominal and recommended timeout values for each command.
Since firmware downloads can take a long time in some devices, and
the time varies greatly between different types of devices, take
advantage of the infrastructure used by the camcontrol opcodes
subcommand to determine the best timeout to use for the WRITE
BUFFER command in SCSI device firmware downloads.
If the device recommends a timeout, it is likely to be more
accurate than the default 50 second timeout used by the firmware
download code. If the user specifies a timeout, it will override
the default or device recommended timeout. If the device doesn't
support timeout descriptors, we fall back to the default.
9. Instead of downloading firmware to SATA drives behind a SAS controller
using WRITE BUFFER, use the SCSI ATA PASS-THROUGH command to compose
an ATA DOWNLOAD MICROCODE command and it to the drive. The previous
version of this code attempted to send a SCSI WRITE BUFFER command to
SATA drives behind a SAS controller. Although that is part of the
SAT-3 spec, it doesn't work with the parameters used with LSI
controllers at least.
10.Add a new mechanism for making common ATA passthrough and
ATA-behind-SCSI passthrough commands.
The existing camcontrol(8) ATA command mechanism checks the device
type on every command executed. That works fine for individual
commands, but is cumbersome for things like a firmware download
that send a number of commands.
The fwdownload code detects the device type up front, and then
sends the appropriate commands.
11.In simulation mode (-s), if the user specifies the -v flag, print out
the SCSI CDB or ATA registers that would be sent to the drive. This will
aid in debugging any firmware download issues.
sbin/camcontrol/fwdownload.c:
Add a device type to the fw_vendor structure, so that we can
specify different download methods for different devices from the
same vendor. In this case, IBM hard drives (from when they
still made hard drives) and tape drives.
Add a tur_status field to the fw_vendor structure so that we can
specify whether the drive to be upgraded should be ready, not
ready, or whether it doesn't matter. Add the corresponding
capability in fw_download_img().
Add comments describing each of the vendor table fields.
Add HGST and SmrtStor to the supported SCSI vendors list.
In fw_get_vendor(), look at ATA identify data if we have a SATA
device to try to identify what the drive vendor is.
Add IBM firmware file validation. This gets VPD page 0x3, and
compares the Load ID and RU name in the page to the values
included in the header. The validation code will refuse to load
a firmware file if the values don't match. This does allow the
user to attempt a downgrade; whether or not it succeeds will
likely depend on the drive settings.
Add a -q option, and disable all informative output
(progress bars, etc.) when this is enabled.
Re-add the inquiry in the confirmation dialog so the user has
a better idea of which device he is talking to. Add support for
displaying ATA identify data.
Don't automatically disable confirmation in simulation (-s) mode.
This allows the user to see the inquiry or identify data in the
dialog, and see exactly what they would see when the command
actually runs. Also, in simulation mode, if the user specifies
the -v flag, print out the SCSI CDB or ATA registers that would
be sent to the drive. This will aid in debugging any firmware
download issues.
Add a timeout field and timeout type to the firmware download
vendor table. This allows specifying a default timeout and allows
specifying whether we should attempt to probe for a recommended
timeout from the drive.
Add a new fuction, fw_get_timeout(), that will determine
which timeout to use for the WRITE BUFFER command. If the
user specifies a timeout, we always use that. Otherwise,
we will use the drive recommended timeout, if available,
and fall back to the default when a drive recommended
timeout isn't available.
When we prompt the user, tell him what timeout we're going
to use, and the source of the timeout.
Revamp the way SATA devices are handled.
In fwdownload(), use the new get_device_type() function to
determine what kind of device we're talking to.
Allow firmware downloads to any SATA device, but restrict
SCSI downloads to known devices. (The latter is not a
change in behavior.)
Break out the "ready" check from fw_download_img() into a
new subfunction, fw_check_device_ready(). This sends the
appropriate command to the device in question -- a TEST
UNIT READY or an IDENTIFY. The IDENTIFY for SATA devices
a SAT layer is done using the SCSI ATA PASS-THROUGH
command.
Use the new build_ata_cmd() function to build either a SCSI or
ATA I/O CCB to issue the DOWNLOAD MICROCODE command to SATA
devices. build_ata_cmd() figures looks at the devtype argument
and fills in the correct CCB type and CDB or ATA registers.
Revamp the vendor table to remove the previous
vendor-specific ATA entries and use a generic ATA vendor
placeholder. We currently use the same method for all ATA
drives, although we may have to add vendor-specific
behavior once we test this with more drives.
sbin/camcontrol/progress.c:
In progress_draw(), make barlength a signed value so that
we can easily detect a negative value.
If barlength (the length of the progress bar) would wind up
negative due to a small TTY width or a large filename,
set the bar length to the new minimum (10 stars) and
truncate the user's filename. We will truncate it down to
0 characters if necessary.
Calculate a new prefix_len variable (user's filename length)
and use it as the precision when printing the filename.
sbin/camcontrol/camcontrol.c:
Implement a new camcontrol(8) subcommand, "opcodes". The
opcodes subcommand allows displaying the entire list of
SCSI commands supported by a device, or details on an
individual command. In either case, it can display
nominal and recommended timeout values.
Add the scsiopcodes() function, which calls the new
scsigetopcodes() function to fetch opcode data from a
drive.
Add two new functions, scsiprintoneopcode() and
scsiprintopcodes(), which print information about one
opcode or all opcodes, respectively.
Remove the get_disk_type() function. It is no longer used.
Add a new function, dev_has_vpd_page(), that fetches the
supported INQUIRY VPD list from a device and tells the
caller whether the requested VPD page is available.
Add a new function, get_device_type(), that returns a more
precise device type than the old get_disk_type() function.
The get_disk_type() function only distinguished between
SCSI and ATA devices, and SATA devices behind a SCSI to ATA
translation layer were considered to be "SCSI".
get_device_type() offers a third type, CC_DT_ATA_BEHIND_SCSI.
We need to know this to know whether to attempt to send ATA
passthrough commands. If the device has the ATA
Information VPD page (0x89), then it is an ATA device
behind a SCSI to ATA translation layer.
Remove the type argument from the fwdownload() subcommand.
Add a new function, build_ata_cmd(), that will take one set
of common arguments and build either a SCSI or ATA I/O CCB,
depending on the device type passed in.
sbin/camcontrol/camcontrol.h:
Add a prototype for scsigetopcodes().
Add a new enumeration, camcontrol_devtype.
Add prototypes for dev_has_vpd_page(), get_device_type()
and build_ata_cmd().

This includes a new summary mode (-s) for camcontrol defects that
quickly tells the user the most important thing: how many defects
are in the requested list. The actual location of the defects is
less important.
Modern drives frequently have more than the 8191 defects that can
be reported by the READ DEFECT DATA (10) command. If they don't
have that many grown defects, they certainly have more than 8191
defects in the primary (i.e. factory) defect list.
The READ DEFECT DATA (12) command allows for longer parameter
lists, as well as indexing into the list of defects, and so allows
reporting many more defects.
This has been tested with HGST drives and Seagate drives, but
does not fully work with Seagate drives. Once I have a Seagate
spec I may be able to determine whether it is possible to make it
work with Seagate drives.
scsi_da.h: Add a definition for the new long block defect
format.
Add bit and mask definitions for the new extended
physical sector and bytes from index defect
formats.
Add a prototype for the new scsi_read_defects() CDB
building function.
scsi_da.c: Add a new scsi_read_defects() CDB building function.
camcontrol(8) was previously composing CDBs manually.
This is long overdue.
camcontrol.c: Revamp the camcontrol defects subcommand. We now
go through multiple stages in trying to get defect
data off the drive while avoiding various drive
firmware quirks.
We start off by requesting the defect header with
the 10 byte command. If we're in summary mode (-s)
and the drive reports fewer defects than can be
represented in the 10 byte header, we're done.
Otherwise, we know that we need to issue the
12 byte command if the drive reports the maximum
number of defects.
If we're in summary mode, we're done if we get a
good response back when asking for the 12 byte header.
If the user has asked for the full list, then we
use the address descriptor index field in the 12
byte CDB to step through the list in 64K chunks.
64K is small enough to work with most any ancient
or modern SCSI controller.
Add support for printing the new long block defect
format, as well as the extended physical sector and
bytes from index formats. I don't have any drives
that support the new formats.
Add a hexadecimal output format that can be turned
on with -X.
Add a quiet mode (-q) that can be turned on with
the summary mode (-s) to just print out a number.
Revamp the error detection and recovery code for
the defects command to work with HGST drives.
Call the new scsi_read_defects() CDB building
function instead of rolling the CDB ourselves.
Pay attention to the residual from the defect list
request when printing it out, so we don't run off
the end of the list.
Use the new scsi_nv library routines to convert
from strings to numbers and back.
camcontrol.8: Document the new defect formats (longblock, extbfi,
extphys) and command line options (-q, -s, -S and
-X) for the defects subcommand.
Explain a little more about what drives generally
do and don't support.

Initially in_matrote() in_clsroute() in their current state was introduced by
r4105 20 years ago. Instead of deleting inactive routes immediately, we kept them
in route table, setting RTPRF_OURS flag and some expire time. After that, either
GC came or RTPRF_OURS got removed on first-packet. It was a good solution
in that days (and probably another decade after that) to keep TCP metrics.
However, after moving metrics to TCP hostcache in r122922, most of in_rmx
functionality became unused. It might had been used for flushing icmp-originated
routes before rte mutexes/refcounting, but I'm not sure about that.
So it looks like this is nearly impossible to make GC do its work nowadays:
in_rtkill() ignores non-RTPRF_OURS routes.
route can only become RTPRF_OURS after dropping last reference via rtfree()
which calls in_clsroute(), which, it turn, ignores UP and non-RTF_DYNAMIC routes.
Dynamic routes can still be installed via received redirect, but they
have default lifetime (no specific rt_expire) and no one has another trie walker
to call RTFREE() on them.
So, the changelist:
* remove custom rnh_match / rnh_close matching function.
* remove all GC functions
* partially revert r256695 (proto3 is no more used inside kernel,
it is not possible to use rt_expire from user point of view, proto3 support
is not complete)

- convert boot1.efi to corrrectly calculate the lba for what the
media reports and convert the size based on what FreeBSD uses.
The existing code would use the 512 byte lba and convert the
size using 4K byte size.
- make fsck_msdosfs read the boot block as 4K so the read doesn't
fail on a 4Kn drive since FreeBSD will error out parition reads
of a block. Make the bpbBytesPerSec check a multiple of 512 since
it can be 512 or 4K depending on the disk. This allows fsck to
pass checking the EFI partition on a 4Kn disk.
To create the EFI file system I used:
newfs_msdos -F 32 -S 4096 -c 1 -m 0xf8 <partition>
This works for booting 512 and 4Kn disks.
Caveat is that loader.efi cannot read the 4Kn EFI partition. This isn't
critical right now since boot1.efi will read loader.efi from the ufs
partition. It looks like loader.efi can be fixed via making some of the
512 bytes reads more flexible. loader.efi doesn't have trouble reading
the ufs partition. This is probably a simple fix.
I now have FreeBSD installed on a system with 4Kn drives and tested the
same code works on 512.

vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
a UDP packet. This implementation is based on RFC7348.
Currently, the IPv6 support is not fully compliant with the specification:
we should be able to receive UPDv6 packets with a zero checksum, but we
need to support RFC6935 first. Patches for this should come soon.
Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
network stack to support batching, GRO, and GSO. Each frame has to make
two trips through the network stack, and each frame will be at most MTU
sized. Performance suffers accordingly.
Some latest generation NICs have begun to support vxlan HW offloads that
we should also take advantage of. VIMAGE support should also be added soon.

Kernel changes:
* Use 64-bytes structures to hold multi-value variables.

each table algo is capable of holding 32-byte variables).
* Add some placeholders to support per-table value arrays in future.
* Use simple eventhandler-style API to ease the process of adding new
table items. Currently table addition may required multiple UH drops/
acquires which is quite tricky due to atomic table modificatio/swap
support, shared array resize, etc. Deal with it by calling special
notifier capable of rolling back state before actually performing
swap/resize operations. Original operation then restarts itself after
acquiring UH lock.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other

2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.
