ndis(4): Avoid overflow.

This is a long standing problem: our random() function returns an
unsigned integer but the rand provided by ndis(4) returns an int.
Scale it down.

MFC after:  2 weeks

300376 by pfg:
ndis(4): Better mimic the behavior of rand() on Windows.

In ndis(4) we expose a rand() function that was constantly reseeding
with a time depending function every time it was called. This
essentially broke the reasoning behind seeding, and rendered srand()
a no-op.

Keep it simple, just use random() and srandom() as it's meant to work.
It  would have been tempting to just go for arc4random() but we
want to mimic Microsoft, and we don't need crypto-grade randomness
here.

300375 by ian:
Adjust _ALIGNBYTES to the proper value for arm and armv6 arches.  Modern
compilers can emit arm instructions that require 8-byte alignment.  The
alignment-sensitive instructions were added in armv5, which has to be
supported by our combined v4/v5 kernels, so the value is set uncoditionally
for all arm architecture versions.

Also adjust the comment to explain in more detail why the macros have the
form and values they do.

Per advice from bde@, maintain the unsignedness of the value of _ALIGNBYTES
(but do so using his second choice of allowing sizeof() to supply the
unsignedness, rather than just hardcoding '8U', which in my mind would
require an even more verbose comment to explain why it's right).  Also
explain in the comment that the resulting type of _ALIGN() is equivelent
to uinptr_t on arm (32-bit unsigned int), but it's purposely spelled as
"unsigned" to avoid problems with including other header files.  Even
including machine/_types.h to allow use of __uintptr_t causes compilation
failures because of this header being included (indirectly) in asm code.

The discussion that led to this change (albeit at a glacial pace) is at
https://lists.freebsd.org/pipermail/svn-src-head/2014-November/064593.html

Re: newcons splash screen

2016-05-21 Thread Thomas Mueller 
Is the newcons nonsupport for console screensaver related to the nonsupport for 
newcons splash screen?

Situation is the same in NetBSD 7.0_RELEASE and STABLE, and current/head, no 
support for screensaver.  DRMKMS is NetBSD's equivalent/counterpart of 
FreeBSD's newcons.  Boot to console comes up into 250x67, like in FreeBSD after 
exiting X.

AHCI/ADA regression?

2016-05-21 Thread Gary Jennejohn 
There appears to be a regression in AHCI/ADA behavior since r300207.

Starting a test kernel at r300293 results in extremely long timeouts
probing ahcich2 for non-existent multiplier ports.

Here some kernel output:
ahci0: 
port 0xff00-0xff07,0xfe00-0xfe03,0xfd00-0xfd07,0xfc00-0xfc03,
0xfb00-0xfb0f mem 0xfe02f000-0xfe02f3ff irq 22 at device 17.0 on pci0

ahci0: AHCI v1.10 with 6 3Gbps ports, Port Multiplier supported

ahcich2:  at channel 2 on ahci0

ada1 at ahcich2 bus 0 scbus2 target 0 lun 0

/dev/ada1p1 on /home (ufs, local, journaled soft-updates)

An older kernel at r299170 does not exhibit this peculiar behavior and
mounts /home with no delays.

ATA? related trouble with r300299

2016-05-21 Thread Oleg V. Nauman 

 I have faced the issue with fresh CURRENT stopped to boot on my old desktop 
after update to r300299
Verbose boot shows the endless cycle of 

ata2: SATA reset: ports status=0x05
ata2: reset tp1 mask=03 ostat0=50 ostat1=50
ata2: stat0=0x50 err=0x01 lsb=0x00 msb=0x00
ata2: stat1=0x50 err=0x01 lsb=0x00 msb=0x00
ata2: reset tp2 stat0=50 stat1=50 devices=0x3
messages logged to console.

Below is the relevant portion of ATA controller/devices probed/attached during 
the boot:

atapci0:  port 
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xffa0-0xffaf at device 31.1 on pci0
ata0:  at channel 0 on atapci0
atapci1:  port 0xd080-0xd087, 0xd000-0xd003, 
0xcc00-0xcc07,0xc880-0xc883,0xc800-0xc80f irq 19 at device 31.2 on pci0
ata2:  at channel 0 on atapci1
ata3:  at channel 1 on atapci1
ada0 at ata2 bus 0 scbus1 target 0 lun 0
ada0:  ATA-7 SATA 2.x device
ada1 at ata2 bus 0 scbus1 target 1 lun 0
ada1:  ATA8-ACS SATA 3.x device
cd0 at ata0 bus 0 scbus0 target 0 lun 0
cd0: <_NEC DVD_RW ND-3570A 1.11> Removable CD-ROM SCSI device

OK - good to know. I'm going to be travelling for a few days so I won't have
time to do a binary search to find the commit that broke it.
