More i386 PaX MPROTECT fallout

As the first machines I booted with PaX MPROTECT active were completely
diskless, I didn't see any other fallout than the C/C++ compilers.

Once I booted a machine which uses local disk, it turns out that
'fsck_ffs' fails due to expecting to write to the text segment.

As such,

  # paxctl +m /sbin/fsck_ffs

is needed.

It still prints:

  fsck_ffs: text relocations

but otherwise works now.

PIE binaries PaX ASLR+MPROTECT now the default for i386


To turn aslr and mprotect off by default if you are having issues:

sysctl -w security.pax.aslr.global=0
sysctl -w security.pax.mprotect.global=0

To turn off on individual binaries:

paxctl +a /path/to/binary
paxctl +m /path/to/binary

Enjoy,

Intel device issues...

Hello,

    I've ended up with a new Dell Optiplex 7040 in my office
and I'm trying to get NetBSD going on it.   If found that NetBSD
-current (7.99.26) is not recognizing several PCI "products" which includes
the USB hub and the ethernet.   I was wondering if anyone knows
whether I should just add the product IDs to the existing drivers,
(and if so, which drivers) or do I need a new driver?

   The devices are:

   vendor 8086 product a12f (USB serial bus, xHCI, revision 0x31)
   vendor 8086 product a131 (miscellaneous DASP, revision 0x31)
   vendor 8086 product a13a (miscellaneous communications, revision 0x31)
   vendor 8086 product a121 (miscellaneous memory, revision 0x31)
   vendor 8086 product 15b6 (ethernet network, revision 0x31)

   Thanks!

pckbc, com, lpt etc. at isa versus at acpi

Various "basic" PC devices (pckbc, com, lpt, fdc etc.) can either be 
configured "at isa" or "at acpi".
What are the benefits/drawbacks of the two possibilities?

If I Had But Two Little Wings


If I had but two little wings
And were a little feathery bird,
To you I'd fly, my dear!
But thoughts like these are idle things
And I stay here.

But in my sleep to you I fly:
I'm always with you in my sleep!
The world is all one's own.
And then one wakes, and where am I?
All, all alone.

oemname still "NetBSD60" in sys/arch/i386/stand/bootxx/pbr.S


Hi, 

Newb question : is there a reason why oemname is still "NetBSD60" in
the PBR asm code? Also, what is the purpose of it? I googled, but found
no clue. Searching through the i386 code of 7-RELEASE I found no other
refs.  Thanks very much.

Intel Quark

Hello,

    Does NetBSD/i386 include a workaround for the "segfault bug"
in Intel Quark embedded processors?
