Log:
  Don't compress and uuencode the "hexdump -C" output files.  Just
  save them with the $FreeBSD$ tag prepended.  Changes to these
  files are now a lot easier to comprehend, which makes diffs also
  reviewable.

svn commit: r344790 - head/sys/geom/part

2019-03-04 Thread Marcel Moolenaar

Author: marcel
Date: Tue Mar  5 04:15:34 2019
New Revision: 344790
URL: https://svnweb.freebsd.org/changeset/base/344790

Log:
  Revert revision 254095
  
  In revision 254095, gpt_entries is not set to match the on-disk
  hdr_entries, but rather is computed based on available space.
  There are 2 problems with this:
  
  1.  The GPT backend respects hdr_entries and only reads and writes
  that number of partition entries.  On top of that, CRC32 is
  computed over the table that has hdr_entries elements.  When
  the common code works on what is possibly a larger number, the
  behaviour becomes inconsistent and problematic.  In particular,
  it would be possible to add a new partition that on a reboot
  isn't there anymore.
  2.  The calculation of gpt_entries is based on flawed assumptions.
  The GPT specification does not dictate that sectors are layed
  out in a particular way that the available space can be
  determined by looking at LBAs.  In practice, implementations
  do the same thing, because there's no reason to do it any
  other way.  Still, GPT allows certain freedoms that can be
  exploited in some form or shape if the need arises.

New Revision: 324369
URL: https://svnweb.freebsd.org/changeset/base/324369

Log:
  Fix alignment of 'last' in autofill.
  
  'last' is the sector number of the last usable sector. Sector
  numbers start with 0. As such, 'last' is always 1 less than
  the count of sectors and aligning 'last' down as-is means that
  the number of free sectors is pessimized by 'alignment - 1' if
  the number of usable sectors was already a multiple of the
  alignment. Consequently, gpart(8) failed to create a partition
  when the alignment and size were such that it would extend to
  the end of the disk.

A 100MB image, committed as binary file is 100MB of data. The hexdump -C
equivalent is often only a few hundred bytes (due to the many zeroes).
The repo bloat argument has grounds for binary files.

Result files used to start off as binary files.  uuencoding is a given in that 
case.  I eventually switched to using hexdump -C, because that makes it easier 
to analyze and understand differences.  The uuencoding was kept to remain 
independent of version control system, file attributes and end-of-line 
characteristics of the host machine: nothing more annoying that checking out 
textual result files and have test failures because ‘\n’ was replaced by ‘\r\n’.

Even if the files aren’t unencoded, there’s always someone who treats it as 
spammy and a tail of garbage. It’s just a knee-jerk reaction to seeing 
something that isn’t understood, I think. As such, there’s no reason to change 
— in fact, changing would be bloating the repo.

State updates may be pending for state being deleted. This
means that the state is still sitting on either the PFSYNC_S_UPD
or PFSYNC_S_UPD_C queues. What pfsync(4) does in that case is
simply remove the state from those queues and add it to the
PFSYNC_S_DEL queue.

But, pf(4) has already dropped the reference count for state
that’s deleted and the only reference is by pfsync(4) by virtue
of being on the PFSYNC_S_UPD or PFSYNC_S_UPD_C queues. When the
state gets dequeued from those queues, the reference count drops
to 0 and the state is deleted (read: memory freed). But the same
state is subsequently added to the PFSYNC_S_DEL queue — i.e.
after the memory was freed.

HTH,

State updates may be pending for state being deleted. This
means that the state is still sitting on either the PFSYNC_S_UPD
or PFSYNC_S_UPD_C queues. What pfsync(4) does in that case is
simply remove the state from those queues and add it to the
PFSYNC_S_DEL queue.

But, pf(4) has already dropped the reference count for state
that’s deleted and the only reference is by pfsync(4) by virtue
of being on the PFSYNC_S_UPD or PFSYNC_S_UPD_C queues. When the
state gets dequeued from those queues, the reference count drops
to 0 and the state is deleted (read: memory freed). But the same
state is subsequently added to the PFSYNC_S_DEL queue — i.e.
after the memory was freed.

HTH,

svn commit: r309394 - head/sys/netpfil/pf

2016-12-01 Thread Marcel Moolenaar

Author: marcel

URL: https://svnweb.freebsd.org/changeset/base/309394

Log:
  Fix use-after-free bugs in pfsync(4)
  
  Use after free happens for state that is deleted. The reference
  count is what prevents the state from being freed. When the
  state is dequeued, the reference count is dropped and the memory
  freed. We can't dereference the next pointer or re-queue the
  state.

svn commit: r308344 - head/usr.sbin/makefs

2016-11-05 Thread Marcel Moolenaar

Author: marcel
Date: Sat Nov  5 16:23:33 2016
New Revision: 308344
URL: https://svnweb.freebsd.org/changeset/base/308344

Log:
  Assign a random number to di_gen (for FFS), instead of extracting it
  from struct stat.  We don't necessarily have permissions to see the
  generation number and the host OS may not have st_gen in struct stat
  anyway.  Since the kernel assigns random numbers, there's nothing
  meaningful about the generation that requires us to preserve it when
  the file system image is created.  With this change, all generation
  numbers come from random() and that makes it easier to add support
  for reproducible builds at some time in the future (i.e. by adding
  an argument to makefs that changes the behaviour of random() so that
  it always returns 0 or some predictable sequence).

New Revision: 307967
URL: https://svnweb.freebsd.org/changeset/base/307967

Log:
  Allow config to be compiled from another source directory, such as one
  for building tools. This boils down to replacing ${.CURDIR} with
  ${SRCDIR}, where the latter is the directory in which this makefile
  lives.
  
  Also allow overriding where file2c comes from using ${FILE2C}.

2016-10-25 Thread Marcel Moolenaar

New Revision: 307927
URL: https://svnweb.freebsd.org/changeset/base/307927

Log:
  Be more precise when including headers so that we're less likely to
  depend on namespace pollution and as such become more portable. This
  means including headers like  or , but also
  making sure we include system/host headers before local headers.
  
  While here: define ENOATTR as ENOMSG in mtree.c. There is no ENOATTR
  on Linux.
  
  With this, makefs is ready for compilation on macOS and Linux.

Log:
  Allow building makefs(8) from another Makefile (such as one in
  a seperate directory hierarchy used to build tools). This boils
  down to replacing the use of ${.CURDIR} with either ${SRCDIR}
  or ${SRCTOP}. SRCDIR is defined as the directory in which the
  Makefile lives that bmake(1) is currently reading. Use SRCTOP
  when reaching outside of makefs's directory.

Isn't it a better app idea to maintain the disk/ namespace for includes? 
Thanks! 
You mean, add -I${SRCTOP}//sys/sys on the compile line and change the code to

Unfortunately, that creates conflicts with header files that are included as 
 and match headers we have under sys/sys.

I think a copy would have been best. There is content in the sys/foo.h files 
still that has valid history (not all the lines were moved). Even if you had 
moved it all, I think a copy would still be best. I would only use a move 
if you are completely removing the original file. I'm not sure if there's a 
non-unfun way to recover from this. You might be able to copy the files from 
the previous revision, reapply your changes and then commit that. 
Ok. I’ll work on recovering the history of the original files.

Maybe the repo masters can undo/delete the commit easily and I’ll just 
recommit. Avoids polluting the history…

I'll keep an eye out for my svn -> p4 mirror importer exploding in that area in 
the near future.
this sort of thing makes it very ill, especially files going away and coming 
back.
I just asked svnadm@ for advice. I’m sure they can suggest a way that doesn’t 
blow things up downstream consumers. I’m fine with the manual labor if that’s 
preferred...

I run a svn-> P4 imoprter that is importign at 1:1..  so change 30 in SVN 
is 30 in p4.
If we end up making extra or missing revisions, I'll lose that 1:1 feature 
..e.g.  if 35 in svn maps to 350001  or 34 in p4 that's  a lot less 
useful to me..
I’ll keep that in mind. If svnadm@ has no strong opinions, I’ll manually fix it 
up using commits.

Thanks for the info,

Somehow this destroyed the history on these files. They showed up as 
deleted and then added instead of modified. If you 'svn log' on them 
now you only get this commit and none of the previous history. I've 
no idea if there's a way to recover this? Had you originally done an 
'svn mv' in your checkout and then copied the files back over or some 
such? 
I did a move from sys/X.h to sys/disk/X.h. The history moved to sys/disk/X.h. 
New files were put where the old files used to be.

Should I have done a svn copy?

All of these routines are available in the "libbsd" sys/queue.h. You 
might find other helpful portability/compatibility routines there, 
requiring fewer changes to the FreeBSD mkimg. 
Oh, nice. I’ll take a look.

Not sure. The max is just for input checking. We do not even try to deal with 
an lseek(2) implementation that doesn’t take a 64-bit offset argument. Granted, 
the use of OFF_MAX before was based on FreeBSD’s lseek(2) implementation and 
was chosen to match it, knowing very well that it has a 64-bit offset argument. 
If lseek(2) doesn’t take a 64-bit offset then mkimg(1) fails for images larger 
than 2GB, but the problems with that run deeper than the max capacity that a 
user can specify on the mkimg command line. Not using OFF_MAX is a clear 
indication that the limit is not fully determined by lseek(2), but to a greater 
extend by the datatype used to hold the capacity.

Hence by preference for going with INT64_MAX. Easy to change if people feel I 
should keep using OFF_MAX.

Log:
  Replace STAILQ with TAILQ. TAILQs are portable enough that they can
  be used on both macOS and Linux. STAILQs are not. In particular,
  STAILQ_LAST does not next on Linux. Since neither STAILQ_FOREACH_SAFE
  nor TAILQ_FOREACH_SAFE exist on Linux, replace its use with a regular
  TAILQ_FOREACH. The _SAFE variant was only used for having the next
  pointer in a local variable.

  Portability changes:
  1.  macOS nor Linux have MAP_NOCORE nor MAP_NOSYNC. Define as 0.
  2.  macOS doesn't have SEEK_DATA nor SEEK_HOLE. Define as -1
  so that lseek will return -1 (with errno set to EINVAL).
  3.  gcc correctly warns that error is assigned but not used in
  image_copyout_region().  Fix by returning on the first error.

Hi, 

Yeah, for portable-y stuff, I'd recommend: 

#include "endian.h" -> #ifdef __FreeBSD__ #include  
#elif __Apple__ etc, etc. 

That way we don't duplicate contents. 

Same with sys/queue.h, etc. 
We may even want to do , , etc. The compat 
directory can be shared by all build utilities that need portability.  That way 
we only have to solve portability problems once.  The name compat is but a

New Revision: 306330

Log:
  Avoid depending on the  header for le*enc and be*enc.
  Not only is the header unportable, the encoding/decoding functions
  are as well.  Instead, duplicate the handful of small inlines we
  need into a private header called endian.h.
  
  Aside: an alternative approach is to move the encoding/decoding
  functions to a separate system header.  While the header is still
  nonportable, such an approach would make it possible to re-use the
  definitions by playing games with include paths. This may be the
  preferred approach if more (build) utilities need this.  This
  change does not preclude that.  In fact, it makes it easier.

  Eliminate the use of EDOOFUS.  The error code was used to signal
  programming errors, but is really a poor substitute for assert.

Hi, 

probably old *.So files now should be removed using `make delete-old` or 
something like this.
make “delete-old” is not for pruning files or directories in the object tree 
(unless that changed while I wasn’t paying attention. Has that changed?

Portability.  We need mkimg to compile on other OSes besides FreeBSD.  In 
particular, macOS and Linux.  It’s ok that constructors are not 100% portable…

Log:
  When MAKEOBJDIRPREFIX points to a case-insensitive file system, the
  build can break when different source files create the same object
  files (case-insensitivity speaking).  This is the case for _Exit.c
  and _exit.s.  Compile _Exit.c as C99_Exit.c

New Revision: 296099
URL: https://svnweb.freebsd.org/changeset/base/296099

Log:
  Add vm_set_register() and vm_set_desc() callbacks. These callbacks
  translate directly into calls to their namesake API functions in
  libvmmapi.
  
  It is an improvement over the existing setreg(), setmsr(), setcr()
  setgdt() and exec() callbacks in that the new additions give full
  control and don't assume we're booting FreeBSD, like exec() and
  don't assume one only wants to set the value of RSP, like setreg().

For ia64 I linked the kernel against a virtual address. The loader
could simply allocate EFI memory as needed, and not worry about
its location. It would map that into what I called the “pre-boot
virtual address space”. When booting the kernel, the loader only
had to pass the physical address and size of the page table (the
virtual address was fixed).

With a variable size the loader would start off with a single 4KB
page table and it would grow it as needed to some arbitrary max.
The page size for the pre-boot virtual address space was 64KB (to
match the maximum alignment of segments that the toolchain allowed).

With more than 700MB of pre-boot virtual address space, one could
preload and entire installation CD if willing to wait for it being
loaded. No need to set memory aside and hope things fit...

As a nice plus: linking against a virtual address allows copying
the kernel text across the memory domains and always have it run
locally to CPUs in NUMA configurations.

2015-09-07 Thread Marcel Moolenaar

Author: marcel

New Revision: 287538
URL: https://svnweb.freebsd.org/changeset/base/287538

Log:
  As expected, things aren't as simple as hoped. Consequently, we have
  no option but to use the smbios information to fill in the blanks.
  It's a good thing UGA is a protocol of the past and GOP has all the
  info we need.
  
  Anyway, the logic has been tweaked a little to get the easier bits
  of information up front. This includes the resolution and the frame
  buffer address. Then we look at the smbios information and define
  expected values as well as the missing bits (frame buffer offset and
  stride). If the values obtained match the expect values, we fill in
  the blanks and return. Otherwise we use the existing detection logic
  to figure it out.
  
  Rename the environment variables from uga_framebuffer abd uga_stride
  to hw.efifb.address and hw.efifb.stride. The latter names are more
  in line with other variable names.
  
  We currently have hardcoded settings for:
  1.  Mid-2007 iMac (iMac7,1)
  2.  Late-2007 MacBook (MacBook3,1)

  Auto-detect the UGA frame buffer and stride on a MacBook. We're
  striking a delicate balance between exhaustive searching and
  banking on assumptions. The environment variables can be used
  as a fall-back anyway. With this change, all known and tested
  Macs with only UGA should have a working console out of the
  box... for now...

Log:
  My MacBook has UGA only, but we fail to detect any changes
  in the frame buffer when we flip pixels. Allow the detection
  to be bypassed by setting the uga_framebuffer and uga_stride
  variables. The kernel console works fine even when we can't
  detect pixel changes in the frame buffer, which indicates
  that the problem could be with reading from the frame buffer
  and not writing to it.

New Revision: 287422
URL: https://svnweb.freebsd.org/changeset/base/287422

Log:
  For UGA, the frame buffer address obtained by scanning the
  PCI BARs does not necessarily correspond to the upper-left
  most pixel. Scan the frame buffer for which byte changed
  when changing the pixel at (0,0).
  
  Use the same technique to determine the stride. Except for
  changing the pixel at (0,0), we change the pixel at (0,1).

  Add a gop command to help diagnose VT efifb problems. The gop
  command has the following sub-commands:
list  - list all possible modes (paged)
get   - return the current mode
set mode- set the current mode to mode
 
 
 This is duplicating the functionality of the `mode' command.  Please
 remove the mode command.

It doesn’t. The mode command works on text modes only. This
command works on the Graphics Output Protocol (GOP) modes.

 
 Also, 'gop' is pretty weird for a command name.  Maybe we can change
 that to something more user friendly?

Maybe.

2015-08-30 Thread Marcel Moolenaar

Author: marcel
Date: Sun Aug 30 23:58:53 2015
New Revision: 287317
URL: https://svnweb.freebsd.org/changeset/base/287317

Log:
  Add support for the UGA draw protocol. This includes adding a
  command called 'uga' to show whether UGA is implemented by the
  firmware and what the settings are. It also includes filling
  the efi_fb structure from the UGA information when GOP isn't
  implemented by the firmware.
  
  Since UGA does not provide information about the stride, we
  set the stride to the horizontal resolution. This is likely
  not correct and we should determine the stride by trial and
  error. For now, this should show something on the console
  rather than nothing.
  
  Refactor this file to maximize code reuse.

svn commit: r287190 - head/sys/kern

2015-08-26 Thread Marcel Moolenaar

Author: marcel
Date: Thu Aug 27 04:25:27 2015
New Revision: 287190
URL: https://svnweb.freebsd.org/changeset/base/287190

Log:
  An error of -1 from parse_mount() indicates that the specification
  was invalid. Don't trigger a mount failure (which by default means
  a panic), but instead just move on to the next directive in the
  configuration. This typically has us ask for the root mount.

New Revision: 286867

Log:
  Support frame buffers that are larger than the default screen
  size as defined by VT_FB_DEFAULT_WIDTH and VT_FB_DEFAULT_HEIGHT
  (at this time 2048x1200). The default is really a max. We cap
  the height and width to those defaults and position the screen
  in the center of the frame buffer.
  
  Ideally we use a bigger font to utility the entire real estate
  that is the frame buffer, but that's seen as an improvement over
  making it work first.

svn commit: r286809 - head/sys/dev/vt/hw/efifb

2015-08-15 Thread Marcel Moolenaar

Author: marcel
Date: Sat Aug 15 16:13:28 2015
New Revision: 286809
URL: https://svnweb.freebsd.org/changeset/base/286809

Log:
  Improve support for Macs that have a stride not equal to the
  horizonal resolution (width). In those cases fb_bpp ended up
  completely wrong -- as in 6 bytes per pixel or something like
  that. Since we already have a way to calculate fb_depth given
  the masks and fb_bpp is effectively the same as fb_depth, all
  we need to do is make sure fb_bpp is rounded to the next
  multiple of the number of bits in a byte -- we assume we can
  divide by the number of bits in a byte throughout vt(4).
  While here:
  -   simplify how we calculate fb_depth.
  -   use fb_bpp instead of fb_depth to calculate fb_stride;
  we know we can divide fb_bpp.
  -   don't limit fb_width and fb_height by VT_FB_DEFAULT_WIDTH
  and VT_FB_DEFAULT_HEIGHT (resp.). Those constants have
  not relation to the size of the frame buffer.
  
  This at least fixes lower-resolution Macs. We're talking
  1280x1024 or so. There still is a problem with 27 Macs,
  which typically have a horizontal resolution over 2K.

svn commit: r286723 - head/sys/dev/vt/hw/vga

2015-08-13 Thread Marcel Moolenaar

Author: marcel
Date: Thu Aug 13 14:43:11 2015
New Revision: 286723
URL: https://svnweb.freebsd.org/changeset/base/286723

Log:
  Fix text mode operation.
  
  We first map 64KB at 0xA and then determine whether to work
  in text or graphics mode.  When graphics mode, the mapping is
  precisely what we need and everything is fine.  But text mode,
  has the frame buffer relocated to 0xB8000. We didn't map that
  much to safely add 0x18000 bytes to the base address.
  
  Now we first check whether to work in text or graphics mode and
  then map the frame buffer at the right address and with the
  right size (0xA+64KB for graphics, 0xB8000+32KB for text).

Author: marcel
Date: Thu Aug 13 15:16:34 2015
New Revision: 286727
URL: https://svnweb.freebsd.org/changeset/base/286727

Log:
  Change md(4) to use weak symbols as start, end and size for the embedded
  root disk. The embedded image is linked into the kernel in the .mfs
  section.
  
  Add rules and variables to kern.pre.mk and kern.post.mk that handle the
  linking of the image. First objcopy is used to generate an object file.
  Then, the object file is linked into the kernel.

 I just upgraded to 4.3.30 and 5.0.0. Both fail the same way. I've just
 attached a screenshot. Will open a bug.

 This change causes my FreeBSD instance in Virtualbox 4.3.28 (OS X) to
 crash. As soon as the kernel initializes the graphics on startup
 (read: before printing any messages), I see random garbage appear on
 screen, followed by a popup dialog from Virtualbox that a fatal
 machine exception has occurred.

Would you mind creating a PR so that we can track the various
console issues pre and post this change.

Details as to how to reproduce would be much appreciated!

No problems are seen with VB 5.0 on Mac OS X and having BIOS (don’t
know if VB even supports UEFI) and with FreeBSD/amd64.

Maybe upgrading to 4.3.30 resolves the issue?

+.Ss I/O port resources
+Device special files created for I/O port resources allow
+.Xr lseek 2 ,
+.Xr read 2 ,
+.Xr write 2
+and
+.Xr ioctl 2
+operations to be performed on them.
+The
+.Xr read 2
+and
+.Xr write 2
+system calls are used to perform input and output (resp.) on the port.
+The amount of data that can be read or written at any single time is either
+1, 2 or 4 bytes.
+While the
+.Nm
+driver does not prevent reading or writing 8 bytes at a time for some
+architectures, it should not be assumed that such actually produces
+correct results.
+The
+.Xr lseek 2
+system call is used to select the port number, relative to the I/O port
+region being represented by the device special file.
+If, for example, the device special file corresponds to an I/O port region
+from 0x3f8 to 0x3ff inclusive, then an offset of 4 given to lseek with a
+whence value of SEEK_SET will target port 0x3fc on the next read or write
+operation.
+The
+.Xr ioctl 2
+system call can be used for the
+.Dv PROTO_IOC_REGION
+request.
+This ioctl request returns the extend of the resource covered by this
+device special file. The extend is returned in the following structure:
+.Bd -literal
+struct proto_ioc_region {
+unsigned long   address;
+unsigned long   size;
+};
+.Ed
+.Ss Memory mapped I/O resources
+The device special files created for memory mapped I/O resources behave
+in the same way as those created for I/O port resources.
+Additionally, device special files for memory mapped I/O resources allow
+the memory to be mapped into the process' address space using
+.Xr mmap 2 .
+Reads and writes to the memory address returned by
+.Xr mmap 2
+go directly to the hardware.
+As such the use of
+.Xr read 2
+and
+.Xr write 2
+can be avoided, reducing the access overhead significantly.
+Alignment and access width constraints put forth by the underlying device
+apply.
+Also, make sure the compiler does not optimize memory accesses away or has
+them coalesced into bigger accesses.

+A device special file named
+.Pa busdma
+is created for the purpose of doing DMA.
+It only supports
+.Xr ioctl 2
+and only for the
+.Dv PROTO_IOC_BUSDMA
+request.
+This device special file does not support

+nor
+.Xr write 2 .

+follows:

+A short description of these is given below.
+.Ss QCOW and QCOW2
+QCOW stands for QEMU Copy On Write.
+It's a sparse file format akin to VHD and VMDK and QCOW represents the
+first version.
+QCOW2 represents version 2 of the file format.
+Version 2 is not backward compatible with version 1 and adds support for
+snapshots among other things.
+The QCOW file formats are natively supported by QEMU and Xen.
+To write QCOW, specify
+.Fl f Ar qcow
+on the command line.
+To write version 2 QCOW, specify
+.Fl f Ar qcow2
+on the command line.
+The preferred file extension is .qcow iand .qcow2 for QCOW and QCOW2
+(resp.), but .qcow is sometimes used for version 2 files as well.
+.Ss RAW file format
+This file format is a sector by sector representation of an actual disk.
+There is no extra information that describes or relates to the format
+itself. The size of the file is the size of the (virtual) disk.
+This file format is suitable for being copyied onto a disk with utilities
+like
+.Nm dd .
+To write a raw disk file, either omit the
+.Fl f
+option, or specify
+.Fl f Ar raw
+on the command line.
+The preferred file extension is one of .img or .raw, but there's no
+real convention for it.
+.Ss Dynamic VHD and Fixed VHD
+Microsoft's Virtual Hard Disk file formats.
+The dynamic format is a sparse format akin to QCOW and VMDK.
+The fixed format is effectively a raw format with a footer appended to the
+file and as such it's often indistinguishable from the raw format.
+The fixed file format has been added to support Microsoft's Azure platform
+and due to inconsistencies in interpretation of the footer is not compatible
+with utilities like
+.Nm qemu
+when it is specifically instructed to interpreted the file as a VHD file.
+By default
+.Nm qemu
+will treat the file as a raw disk file, which mostly works fine.
+To have
+.Nm
+create a dynamic VHD file, specify
+.Fl f Ar vhd
+on the command line.
+To create a fixed VHD file for use by Azure, specify
+.Fl f Ar vhdf
+on the command line.
+The preferred file extension is .vhd.
+.Ss VMDK
+VMware's Virtual Machine Disk file format.
+It's a sparse file format akin to QCOW and VHD and supported by many
+virtualization solutions.
+To create a VMDK file, specify
+.Fl f Ar vmdk
+on the command line.
+The preferred file extension is .vmdk.
+.Pp
+Not all virtualization solutions support all file formats, but often those
+virtualization environments have utilities to convert from one format to
+another.
+Note however that conversion may require that the virtual disk size is
+changed to match the constraints of the output format and this may invalidate
+the contents of the disk image.
+For example, the GUID Partition Table (GPT) scheme has a header in the last
+sector on the disk.
+When changing the disk size, the GPT must be changed so that the last header
+is moved accordingly.
+This is typically not part of the conversion process.
+If possible, use an output format specifically for the environment in which
+the file is intended to be used.

  size of the image is what counts.
 
 
 I'll test this out on the next 11-CURRENT builds.  (Based on the content
 of the commit log, it's unclear to me if you received my last reply on
 this topic, so if you didn't let me know.)

I tested this in Azure: the fixed format VHD hasn't been
changed.

svn commit: r286212 - head/tools/bus_space/examples

2015-08-02 Thread Marcel Moolenaar

Author: marcel
Date: Sun Aug  2 21:24:03 2015
New Revision: 286212
URL: https://svnweb.freebsd.org/changeset/base/286212

Log:
  Add an example program (in Python) for the AMD Am79c900 (ILACC)
  ethernet controller. The ethernet controller is emulated by VMware
  Fusion (for example) and is a good device to demonstrate how to use
  the bus space and busdma functions due to its simple programming.
  
  The program sets up the DMA structures, sends a DHCP discover packet,
  waits 2 seconds, and iterates over the receive ring for an offer.

Added:
  head/tools/bus_space/examples/
  head/tools/bus_space/examples/am79c900_diag.py   (contents, props changed)

+Simple diagnostics program fo the AMD Am89c900 series ILACC.
+This ethernet controller is emulated by VMware Fusion among
+possibly other virtualization platforms.
+
+The datasheet can be found here:
+http://support.amd.com/TechDocs/18219.pdf
+
+This example program sends a single DHCP discovery packet,
+waits 2 seconds and then iterates over the receive ring for
+a targeted packet.
+
+For this program to function, connect the network interface
+to a network with a DHCP server. In VMware Fusion this can
+best be done by configuring the interface as a NAT interface
+using the Share with my Mac setting.

Log:
  Change the dev argument from a full path to just the device
  identification (e.g. isa:0x3f0 or pci0:2:1:0). In libbus,
  the device is turned into a path name. For bus_space_map(),
  the resource is now specified in a second argument.
  Before:
bus.map('/dev/proto/pci0:2:1:0/pcicfg')
busdma.tag_create('/dev/proto/pci0:2:1:0/busdma', ...)
  Now:
bus.map('pci0:2:1:0', 'pcicfg')

  o   make sure the boundary is a power of 2, when not zero.
  o   don't convert 0 to ~0 just so that we can use MIN. ~0 is not a
  valid boundary. Introduce BNDRY_MIN that deals with 0 values
  that mean no boundary.
