Example scripts and supporting files for creating Amazon EC2 AMIs
(Amazon Machine Images) running NetBSD.  Requires an Amazon EC2 account.
Please test and extend these scripts!

The original scripts were written by Jean-Yves Migeon, heavily modified

From the README:

Notes on using these scripts for creating EC2 AMIs
--------------------------------------------------

Here are some assumptions made:

- You have the EC2 API tools already set up.  If you don't already, the
  easiest way to do so is to install the misc/ec2-api-tools package
  from pkgsrc.  An easy way to check if they're set up properly is
  if you can run "ec2-describe-instances" without an error.

- You are running this from a NetBSD system.  It's certainly not impossible
  to update this for running on another platform, but it'll be necessary
  to adapt to using a NetBSD tools build for (at least) makefs.

- Your default EC2 profile allows ssh to your running instances from
  the location you're running this script!

- The most-used (and tested!) script (create_ec2_ami.sh) assumes that there
  are NetBSD 6.0 AMIs available on EC2 already, for bootstrapping.  The
  public images in account 101367081206 (an account owned by me, Jeff Rizzo,
  a NetBSD developer) are available for use, and are searched in addition
  to the user's own AMIs.  You can also specify a particular AMI to use
  for the bootstrapping.  There is another script (create-new.sh) which
  is less well tested, and which may currently be broken, which allows
  you to use a Linux AMI to create a NetBSD one.  You will need to
  create a 'bootstrap' image with an ext2 file system (see build_ec2_img.sh,
  specifically the "-b" flag).

CREATING AN AMAZON MACHINE IMAGE (AMI)
--------------------------------------

Once you've verified the Amazon EC2 command-line tools work (see above),
the basic workflow is as follows:

- Edit the set_ec2_env.sh script to have the location of your certs/keys.
  This file is read by several of the scripts.

- Either build sets with build.sh, or identify where the release you want to
  base your AMI on lives.  You can access built sets via http, ftp, or on
  the local fs.

- Build an image for upload, using the build_ec2_img.sh script.  This
  image will contain everything *except* the kernel (the kernel will be
  on a separate ext2fs partition, due to EC2 boot requirements), and will
  be resized to fit the volume created in the AMI creation script.

  An example of doing this:

  ./build_ec2_img.sh -d http://ftp.netbsd.org/pub/NetBSD/NetBSD-6.0_BETA/amd64/binary/sets

  ...this will create an image file in the current directory.

- Create the AMI from the above image plus a kernel.  You have to
  specify which region to create the AMI in:

  ./create_ec2_ami.sh -i ./NetBSD-AMI.img.xz -a x86_64 -d "AMI description goes here" -k http://ftp.netbsd.org/pub/NetBSD/NetBSD-6.0_BETA/amd64/binary/kernel/netbsd-XEN3_DOMU.gz -v "6.0_BETA-or-whatever-version-string-you-want" us-east-1

The process can take anywhere from 10-60 minutes, depending on which region
you choose and how fast your connection is for uploading.  After a successful
run, be sure to test your AMI!

ATF test for SIGBUS => BUS_ADRALN (invalid address alignment).

That one is tedious to test under x86: alignment exceptions are
not reported by this architecture unless you ask for them explicitely (by
setting the PSL_AC bit). The brokenness does not end there: %cr2 should
contain the address where the unaligned access occured, alas, it does not.

I am not aware of other architectures where this could happen. Still, my
knowledge is limited; if there is one, feel free to send me a mail and I
will update the test accordingly.

Adding insult to injury, this test can fail in various funny ways with VMs:
- under x86 QEMU, no trap() happens. As ring 3 code stays almost untouched by
QEMU VMM, I suppose the exception can only be triggered when the host
itself is capable of catching unaligned accesses.
- under Virtual Box with HVM support, i386 works fine, but amd64 fails with a
SIGILL (Illegal instruction) that happens right before entering the
signal handler. No idea why, and trying to debug it with gdb freezes the VM
(including ddb breaks).

Anyway, tested with:
- i386: P4 host, anita, Virtual Box HVM (Mac OS X)
- amd64: anita, Virtual Box HVM (Mac OS X)

XXX I would appreciate if someone could test it under a real amd64 host with
an up-to-date kernel, so I can reasonably assume that the culprit is
Virtual Box and not our amd64 port (my test machine being off line
I cannot do it myself). Results from other arches would be a plus too.

  an adaptive mutex.  Can't do that.  Reordering this requires changing

  reseed on failure, or we could deadlock.
2) Can't free memory with a valid mutex in it.

Mirror what is done for amd64 boot and ACPI wakeup code by setting
CR0_WP (write protection bit) early on boot. Although it is set later via
cpu_init(), this can help tracking down invalid writes to pages mapped
as read only from ring 0.

No regression observed when booting under anita (QEMU) or a P4 host.

Depending on your hardware or setup, you may trigger code paths I have
overlooked. So if your machine does not start properly, or you get
page faults early during boot, please report them to me.

Note mpii(4)

(bouyer)

Expand struct scsipi_bustype {} in a ABI-backward-compatible way to
pass more informations about the bus:
- bustype_type has 2 different bytes, one holding the existing
  SCSIPI_BUSTYPE_* (scsi, atapi, ata), and one for a per-SCSIPI_BUSTYPE_*
  subtype. Introduce macros to build or extract bustype_type.
- for SCSIPI_BUSTYPE_SCSI, define subtypes for parallel SCSI, Fibre Channel,
  SAS and USB, to specify the transport method. SCSIPI_BUSTYPE_SCSI_PSCSI
  is 0 so that bustype_type value doesn't change for existing code
- for non-SCSIPI_BUSTYPE_SCSI busses there's no defined subtype yet,
  so the bustype_type value doesn't change.
- provide scsi_fc_bustype, scsi_sas_bustype and scsi_usb_bustype
  along with scsi_bustype to be used by bus driver where appropriate
- scsipi_print_xfer_mode(): more existing code under a
  (SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_PSCSI) case, as
  sync/wide parameters only make sense for parallel SCSI.
  For (SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_FC) and
  (SCSIPI_BUSTYPE_SCSI, SCSIPI_BUSTYPE_SCSI_SAS), only print
  tagged queing status if enabled. Just be silent for other
  bustypes.

This change is prompted by this problem:
right now, FC (e.g. isp(4)) and SAS (e.g. mfi(4)) don't
  do anything for ADAPTER_REQ_SET_XFER_MODE, and especially never
  call scsipi_async_event(ASYNC_EVENT_XFER_MODE), so sd(4) always
  runs untagged. Doing a scsipi_async_event(ASYNC_EVENT_XFER_MODE) with
  appropriate parameters is enough to enable tagged queuing,
  but then scsipi will print:
  sd0: async, 8-bit transfers, tagged queueing
  which is harmless (async, 8-bit transfers doens't make sense on SAS anyway)
  but will confuse users. With this change scsipi will only print:
  sd0: tagged queueing
  which is correct.

In the long run, knowning the underlying transport in scsipi will
allow better handling of device which are not parallel SCSI.

Another change adding an extra callback to struct scsipi_bustype {}
will come (so that scsipi_print_xfer_mode(), which is SCSI-specific,
can be moved out of scsipi_base, and split into per-subtype callback),
but this will break kernel ABI and so is not suitable for
netbsd-6, so will be commmited later. The above is enough to get
tagged queuing on FC and SAS in netbsd-6.

- In libperfuse, check for corner case where opc = 0 on INACTIVE and  RECLAIM (how is it possible? Check for it to avoid a crash anyway)
- In libperfuse, make sure we unlimit RLIMIT_AS and RLIMIT_DATA so that

Address multiple problems with rnd(4)/cprng(9):

1) Add a per-cpu CPRNG to handle short reads from /dev/urandom so that
  programs like perl don't drain the entropy pool dry by repeatedly
  opening, reading 4 bytes, closing.

2) Really fix the locking around reseeds and destroys.

3) Fix the opportunistic-reseed strategy so it actually works, reseeding
  existing RNGs once each (as they are used, so idle RNGs don't get
  reseeded) until the pool is half empty or newly full again.

Pull up following revision(s) (requested by hannken in ticket #183):
sys/fs/msdosfs/msdosfs_fat.c: revision 1.20
pcbmap(): We cannot use bread() here as for the pagedaemon getblk()
may fail leading to a panic in bread().
Replace bread() with getblk() / VOP_STRATEGY() and return
an error if getblk() fails.

Fixes PR#46282: 6.0_BETA crash: msdosfs_bmap -> pcbmap -> bread ->
bio_doread

This is an interim solution for easy pullup.  The final solution
is be to change bread() to not return a buffer on error.  As
we have to change all callers of bread() this will not qualify
for a pullup.

Now that we have amdnb_misc for attaching amdtemp, revert pchb.c revisions
1.27 and 1.32.  This will unbreak the build.

XXX The amdtemp device currently does not seem to provide correct sensor
    values.

XXX The amdnb_misc device does not currently have a rescan capability, so
    the amdtemp module will not instantiate any devices (PR kern/45268
    reappears).

XXX The agp attachment at the same pci device and function (which was
    the motivation for attaching amdtemp at pchb) probably ought to also
    be moved to attach at amdnb_miscbus.
