dee1dd64c3 New APIs: Add support for syslinux and extlinux (bootloaders).
This also adds tests of SYSLINUX and EXTLINUX which create bootable
guests.

e73cd348c8 Don't delete iconv locale data from the appliance.
- /usr/lib{,64}/gconv/*:

This is the iconv data, required for APIs like iconv_open to work.  In
particular, the mtools 'mcopy' program fails completely if it cannot
use iconv.  'mcopy' is used by SYSLINUX to copy files to the disk.

The error you would have seen is:

  Error converting to codepage 850 Invalid argument
  Cannot initialize 'S:'
  Bad target s:/ldlinux.sys

- /usr/bin/localedef and /usr/sbin/build-locale-archive:

These are not really needed, but both are simply small binaries so we
might as well not delete them.

3cdca7616a daemon/copy: Ensure errno is preserved along error paths. 2013-04-04 14:58:32 +01:00
Richard W.M. Jones
33c087ea9c Add 'sparse' option to copy-{device,file}-to-{device,file} calls.
Setting the 'sparse' optional boolean causes writes to be omitted if
the block to be written contains all zero bytes.

This should help with sparse backing files (eg. raw, qcow2, dm-thin, etc).

Also, modify virt-resize to use this option by default when copying
devices.  The savings in virt-resize can be quite startling, eg
'du -sh' (ie. true size) of a resized disk image:

8.1G      /tmp/f15x32-resized.img    # before this change
3.2G      /tmp/f15x32-resized.img    # after this change

2287b988ee perl: Remove use of Sys::Guestfs::Lib::open_guest function.
This obsolete function does all sorts of libvirt/XML things, which can
now be replaced by using ordinary API calls; especially $g->add_domain.

ecda39bed4 tests/data: Update README and comments about initrd binary files.

1cb38ab924 New API: feature-available.
This API is an easier to use version of the existing guestfs_available,
because the new API returns true/false instead of throwing an error
when a feature from the list is not available.

In truth we've had this implementation internally in the library
and several tools and in Sys::Guestfs::Lib for a long time.  This
change just turns it into a publicly consumable API.

1a2e03c323 java: 'make clean' should remove whole api/ directory.
This directory (containing HTML documentation) can be removed
completely when making clean.  CLEANFILES cannot recursively remove a
directory, so use a clean-local rule instead.

ce49e1fdc0 build: Change various check rules so they implicitly act like 'make -k'.
Rules such as 'make check-valgrind' are implemented using a for-loop.
They would always exit after the first error, even if 'make -k' was
used at the top-level.  Since 'make -k'-style behaviour is generally
more useful, change these for-loops so they run all the tests, and
report errors at the end.

b050d7e4bf valgrind: Write separate log files in tmp/valgrind-<DATE>-<PID>.log
Current code wrote a single valgrind.log in the top-level directory.
This was overwritten with each valgrinded program, which wasn't much
use.  The new version writes multiple separate valgrind-*.log files
containing the date and PID (so each is unique).

It would nice if valgrind could delete log files that don't contain
errors, but this doesn't appear to be possible.

68990840b6 "attach method" is from now on known as "backend".
This large, but mainly mechanical commit, renames "attach method"
everywhere to "backend".

Backwards compatibility of the API (guestfs_{set,get}_attach_method)
and environment (LIBGUESTFS_ATTACH_METHOD) is maintained, but in new
code use guestfs_{set,get}_backend and LIBGUESTFS_BACKEND instead.

The default backend (launching qemu directly) is now called 'direct'
instead of 'appliance', although you can still use 'appliance' as a
synonym.

2a090e0667 tests/guests: Add 'guests-all-good.xml{.in}' libvirt test guest set.
This differs from 'guests.xml' in that there are no guests with
missing disks, etc., so we can use this to test virt-alignment-scan
accurately.

429ffda329 parallel: Propagate errors from worker threads and exit with error code.
In virt-df and virt-alignment-scan, ensure that errors that happen in
worker threads are propagated all the way up and result in
exit(EXIT_FAILURE).

Note that this makes the align/test-virt-alignment-scan-guests.sh test
fail (for a genuine reason).  This is fixed in the following commit.

9c32c73afd drives: Allow multiple servers to be passed to add_drives.
This changes the existing (non-published-in-stable) API for
add_drives{_opt} so that instead of having separate 'server' and
'port' parameters, now we have a single 'server' parameter which is a
list of strings.

This is so we will be able to cope with protocols such as Ceph which
allows multiple servers, or Sheepdog which can use an implicit local
server (ie. zero servers specified).

NBD still requires exactly one server.

dir).

The difference in file layout between 'make install' and
'make INSTALLDIRS=vendor install' is shown below (for Fedora 18).

b17c3a7eb3 launch: appliance: Add custom parameters last.
This allows custom parameters to modify parameters added by
libguestfs, eg. by doing:

  -set drive.hd0.file=rbd:foo/bar

[infernix adds the comment below:]

This works for recent versions of QEMU. The way to use this is:

guestfish
><fs> add-drive /dev/null
><fs> config -set drive.hd0.file=rbd:pool/volume
><fs> run

This will probably work for more types (sheepdog, iscsi et al), but
with the caveat that the libguestfs layers are bypassed so you'll
*always* end up directly accessing the disk in rw mode.

6e7cbb09a9 launch: appliance: Use socketpair instead of pipe for qemu stdin/stdout.
The libvirt backend already uses a Unix socket for the appliance
console, and so for the libvirt backend the fields g->fd[0] == g->fd[1].

Change the appliance backend to use a socketpair, so we need just a
single file descriptor for qemu stdin/stdout (ie. appliance console).

Consequently we can remove the array int fd[2] in the handle and
replace it with a single file descriptor.

guestfs_umount_local could generate events, call the error handler, or

ac2f6c4ef2 generator: Add 'wrapper' flag to control when wrapper is generated.
Non-daemon functions normally have a wrapper function called
eg. guestfs_name.  The "real" (ie. hand-written) function is called
eg. guestfs__name.  The wrapper deals with checking parameters and
doing trace messages.

This commit allows the wrapper function to be omitted.  The reason is
so that we can handle a few functions that have to be thread-safe
(currently just: guestfs_user_cancel).  The wrapper is not thread safe
because it can call events and/or the error handler.

When adding a domain (ie. guestfs_add_domain), read the SELinux
<label/> and <imagelabel/> from the guest and use them for the
appliance.  The appliance is statically labelled the same as the
guest, so it is able to read its disks.

However tell libvirt not to try relabelling the disks, to prevent
libvirt from disturbing the existing labels on the disks (in
particular when the libvirt connection is closed, we don't want
libvirt to try to restore some other label on the disks).

</seclabel>

It is ignored by other attach-methods.

34e77af1bf Partial rewrite of virt-df to use parallel threads instead of single appliance.
Previously when you asked virt-df to show stats for all your libvirt
guests, it used a single appliance and tried to attach as many disks
as possible to it, even disks from different guests.

However this has been problematic: Not only is the code to do this
horrendously complex, but it's also insecure, and it doesn't interact
well with sVirt labels (see RHBZ#912499 comment 7).

In the meantime we discovered that running parallel appliances gives
you most of the performance of using a single appliance, but with a
lot less complexity and better guest isolation (see the documentation
in commit 680450f3b4).

Therefore this is a partial rewrite of virt-df so that in this case it
now uses parallel appliances.

Notes:

The '--one-per-guest' option is now the default and only way to do
things; this option now does nothing.

By default, the amount of parallelism to use is controlled by the
amount of free memory seen when virt-df starts up (subject to some
minima and maxima).  The user can control this through new command
line option '-P'.

04723b4dd1 lib: Create libutils convenience library.
The libutils convenience library is a place for code shared between
the main library, language bindings and virt tools.  Note that the
code is statically linked into both the library, each binding and each
tool, but this is an improvement because (a) the source is shared and
(b) libguestfs.so can export fewer private functions.

Currently it contains the cleanup functions, and the functions
guestfs___free_string_list function and guestfs___for_each_disk.

guestfs___for_each_disk has changed so that it no longer
unconditionally sets the error in the guestfs handle.  Instead callers
can control error handling.

(2) debug progress <n> <rate> generates progress messages every <rate>
microseconds for <n> seconds.

The second form omit the usual rate-limiting, and so wouldn't
be generated like this from an ordinary API call.  However this
is useful for testing events (see RHBZ#909624).

The second parameter passed into getline(3) is the size of the

confusing, so rename this parameter as 'allocsize' consistently
throughout the code.

  A public API which queries the library state machine. It is exported

VBindTest:
  An internal API used only for testing language bindings. It is
  guarded by GUESTFS_PRIVATE in the C api, but exported by all other
  language bindings as it is required for testing. If language
  bindings offer any way to guard use of these apis, that mechanism
  should be used. It is not documented anywhere.

VDebug:
  A debugging API. It is exported by all language bindings, and in

VInternal:
  An internal-only API. It is guarded by GUESTFS_PRIVATE in the C api,
  and not exported at all in any other language binding. It is not
  documented anywhere.

4940bd9a9e fish: Be stricter about boolean values.
Previously I noticed that bfan used this command without any error:

                                                   ^^^^^^^^^^

This was because the code allowed any string to be evaluated as a
boolean.

The new code is stricter.  It allows the following strings only case
insensitive (everything else is an error):

  1
  true
  t
  yes
  y
  on

  0
  false

Not to be confused with the libxml2 macro 'BAD_CAST' which converts
from 'signed char *' to 'unsigned char *'.

The 'bad_cast' function was defined and used all over the place as a
replacement for a '(char *)' cast.  I think it is better to make these
casts explicit, instead of hiding them in an obscure function.

ec3b75e5ff Rearrange internal header files.
This commit rearranges the internal header files.

"src/guestfs-internal.h" is just for the library, as before.

"src/guestfs-internal-frontend.h" is for use by all library, bindings,
tools C code, but NOT the daemon.

"src/guestfs-internal-all.h" is for use by all C code including the
daemon.

This is just code motion, but it has some important consequences:

(1) We can use the CLEANUP_* macros in bindings and tools code.

(2) We can get rid of TMP_TEMPLATE_ON_STACK.

(3) We will (in future) be able to stop bindings and tools code from
using the safe_* allocation functions (which are NOT safe to use
outside the library alone).

27b995c841 Make internal-only functions and structures private
Certain functions are intended to be internal only, but we currently

enables private structs, but doesn't implement any.

98b64650c8 lib: Add CLEANUP_* macros which automatically free things when leaving scope.
Use the macro like this to create temporary variables which are
automatically cleaned up when the scope is exited:

  {
    CLEANUP_FREE char *foo = safe_strdup (bar);
    ...
    // no need to call free (foo)!
  }

The following code is also valid.  The initialization of foo as 'NULL'
prevents any chance of free being called on an uninitialized pointer.
It may not be required in all cases.

  {
    CLEANUP_FREE char *foo = NULL;
    ...
    foo = safe_malloc (100);
    ...
    // no need to call free (foo)!
  }

This is also valid:

  {
    CLEANUP_FREE char *foo = ..., *bar = ...;
    ...
    // no need to call free (foo) or free (bar)!
  }

The CLEANUP_FREE_STRING_LIST macro calls guestfs___free_string_list
on its argument.  The argument may be NULL.

The CLEANUP_HASH_FREE macro calls hash_free on its argument.  The
argument may be NULL.

Important implementation note:
------------------------------

On GCC and LLVM, this is implemented using __attribute__((cleanup(...))).

There is no known way to implement this macro on other C compilers, so
this construct will cause a resource leak.

Important note about close/fclose:
----------------------------------

We did NOT implement 'CLEANUP_CLOSE' or 'CLEANUP_FCLOSE' macros.  The
reason is that I am not convinced that these can be used safely.  It
would be OK to use these to collect file handles along failure paths,
but you would still want a regular call to 'close'/'fclose' since you
must test for errors, and so you end up having to do:

  if (close (fd) == -1) {
    // failure case
    // avoid double-close in cleanup handler:
    fd = -1;
    ...
  }
  // avoid double-close in cleanup handler:
  fd = -1;
  ...

d4763a2e24 daemon: Suppress two false positives from Coverity.
Using // coverity[...] or /* coverity[...] */ comments in the source
it is possible to suppress specific Coverity errors.  The suppressed
error should occur in the line following the comment.

In this case I have suppressed two false positives from Coverity:

(a) We deliberately assign to a NULL pointer in order to cause a
segfault, for testing how the library reacts when this happens.
Coverity flags this, but it is not an error in this case.

(b) Coverity does not model global variables (a known shortcoming).
Therefore the code 'errno = posix_memalign (...)' cannot be modelled
by Coverity, even though the code is correct.  Coverity raises a false
positive about this.

(Thanks Kamil Dudka, Coverity)

e73cf67762 inspection: Set fs->device field on swap devices.
For some reason the fs->device field was not set for swap devices.

Apparently this did not matter before (this bug has existed since at
least libguestfs 1.16), but in commit 6ee80b8dac we started to depend
on the fs->device field being non-NULL.  This resulted in segfaults
when inspecting any guest which had a swap device, eg:

 #0  __strcmp_sse42 () at ../sysdeps/x86_64/multiarch/strcmp-sse42.S:164
 #1  0x00007ffff7d740cb in parent_device_already_probed (g=0x703a70,
                        partition=0x6f79b0 "/dev/vda4") at inspect.c:156
 #2  0x00007ffff7d73e00 in guestfs__inspect_os (g=0x703a70) at inspect.c:83
 #3  0x00007ffff7cee11d in guestfs_inspect_os (g=0x703a70) at actions-1.c:397

This commit sets fs->device to the device name.

d1ad89520e tests: Skip windows.img tests if it is zero-sized.
If ntfs-3g is not installed, then tests/guests creates a 'windows.img'
file which is zero-sized.

This is problematical because other tests which use this image will
fail at best, or hit RHBZ#847549 (qemu/virtio-scsi bug) at worst.

Change the tests which use windows.img so they skip if 'windows.img'
has zero size.

c4ad2c0ce3 daemon: Fold stdout on stderr when running e2fsck.
User Phill Bandelow noted that virt-resize fails with an e2fsck error
on a host where the system clock had been accidentally set in the
past.

Unfortunately this was hard to diagnose because guestfsd 'ate' the
stdout of the e2fsck program.  I have verified by code inspection that
e2fsck prints messages on stdout.

Thus this changes the daemon to fold stdout and stderr together so we
get to see all error messages from e2fsck when it fails.

62e775c350 Change the handling of private functions, safe_malloc etc.
Rename guestfs_safe_malloc et al to guestfs___safe_malloc etc.

To use the private functions, code now has to define
-DGUESTFS_PRIVATE_FUNCTIONS=1.  This will make it easier for us in
future to work out which programs are using these functions and to
minimize both the number of programs and the functions they are
calling.

Note that the Perl, Python, OCaml, Ruby and Java bindings use
guestfs_safe_* calls.  None of the other bindings do.  This is a bug
(in the bindings using those functions): these functions will call the
out of memory callback on failure.  This function defaults to abort(),
and since this happens from a language binding, there is no way to
change this default.

2aa731e7c4 daemon: Remove redundant fork in commandrvf
Currently the code is doing a redundant fork when passed the
COMMAND_FLAG_CHROOT_COPY_FILE_TO_STDIN flag. The additional
sub-process does a chroot() which has no effect because all file
handles are already open at that point, then simply copies its input
to its output.

This change simply replaces the above with a dup2 of the passed file
handle to STDIN of the command process.

52cd07a0ac daemon: fix directory outside current root when executing commands
When executing a command, we temporarily chroot, fork and exec the
command, then chroot back. We intentionally don't chdir in the parent
process so that we can 'jailbreak' the chroot later. However, this has
the effect that commands are executed with a current working directory
which is outside the current root.  This unusual state can cause
errors in executed commands which don't anticipate it.

This change does a chdir("/") before executing and command. This
happens inside the fork, so the jailbreak isn't affected in the
parent.

25652a6d5c proto: Free drives array when qemu subprocess dies abruptly.
Commit ed7fda161e changed the g->drives
linked list into an array, and also made a subtle change to the
(undocumented) semantics of drives in the rare case when qemu is
relaunched.

Every time we go back to the CONFIG state, we should free the drives
array.  However there was one place where this was not happening.
This was caught by the tests of the protocol, but only when using the
default (appliance) method, not the libvirt method which we were more
interested in testing in Fedora.

When testing on Debian using the appliance method, we therefore hit
this bug for the first time.

This relates to or fixes the following commits:

7d2ae9f30f daemon: Generate the code when libraries are statically not available.
Since we as developers rarely test the case where some library is
statically not available, that side of the code was hardly tested,
except by unfortunate users in the field who often hit cases where
functions were missing or misdeclared.  In fact, when making this
change I noticed several bugs like that.

Change it so that this code is autogenerated, and therefore always
correct and up to date.

Previous code which looked like this:

  int
  optgroup_acl_available (void)
  {
    return 0;
  }

  char * __attribute__((noreturn))
  do_acl_get_file (const char *path, const char *acltype)
  {
    abort ();
  }

  /* etc */

is replaced by a single line:

Comment from Coverity:

  libguestfs-1.19.66/erlang/erl-guestfs-proto.c:115: sign_extension:
  Suspicious implicit sign extension: "buf[0]" with type "unsigned char"
  (8 bits, unsigned) is promoted in "(buf[0] << 24) | (buf[1] << 16) |
  (buf[2] << 8) | buf[3]" to type "int" (32 bits, signed), then
  sign-extended to type "unsigned long" (64 bits, unsigned).  If
  "(buf[0] << 24) | (buf[1] << 16) | (buf[2] << 8) | buf[3]" is greater
  than 0x7FFFFFFF, the upper bits of the result will all be 1.

5a2e320ec9 configure: Add --enable-code-profiling and --enable-code-coverage flags.
These configure flags enable code profiling (with gprof) and code
coverage (with gcov) respectively.

Although this is a nice idea, it's not currently very useful.

Libtool mangles filenames in such a way that gcov cannot locate its
datafiles.

Profiling is of dubious utility with libguestfs which is not CPU-bound
and relies extensively on running external programs (oprofile-like
system profiling that took into account libguestfs + qemu or
libguestfs + qemu + the appliance + filesystem tools *would* be
useful).

Also neither flag will help in capturing data from the appliance.

  does *not* contain any Windows logo as a resource (I checked).
  Therefore the "basket icon" that this produces is just a stand-in
  until we have a better idea for solving this problem.

a4c0d7a82a launch: appliance: Handle non-\0 terminated buffer correctly.
The read_all function is used as a callback for

  guestfs___cmd_set_stdout_callback (cmd, read_all, [str],
                                     CMD_STDOUT_FLAG_WHOLE_BUFFER);

As noted in the documentation for CMD_STDOUT_FLAG_WHOLE_BUFFER, the
buffer returned is not \0-terminated, and so using memdup will create
an unterminated string, and therefore potentially a memory overrun
when reading or searching the string.

Use strndup instead so the final string is \0-terminated.

aeea803ad0 appliance: Pass lpj=... on the appliance command line (thanks Marcelo Tosatti).
Try to get the host's loops_per_jiffy value and pass this on the
command line to the guest.  In theory this should avoid the appliance
having to recalculate this value in a VM with TCG (which is generally
error-prone).  This should avoid timing issues.

We only do this when we are certain that the guest will be TCG.
Currently we only have enough information to do this from the libvirt
attach-method.  So mostly this will only affect people using Fedora in
a VM.

The host loops_per_jiffy value is not exported by the kernel.  It is
only printed by the kernel early during boot, so if boot messages have
"scrolled off" the kernel ring buffer, it won't be available.  Some
operating systems save early kernel messages in /var/log/dmesg but (a)
Fedora 18+ seem to have abandoned this file and (b) on Ubuntu this
file is unreadable for spurious "security" reasons.

I have submitted a patch to make lpj available through /proc/cpuinfo.

==13629== 498 (112 direct, 386 indirect) bytes in 1 blocks are definitely lost in loss record 99 of 110
==13629==    at 0x4A06B2F: calloc (vg_replace_malloc.c:593)

==13629==    by 0x402E7E: main (virt-filesystems.c:349)

Also adjust the command code in several places to make it simpler.  We
can almost always call guestfs___cmd_close right after
guestfs___cmd_run, avoiding any need to close the handle along error
paths.

Tested by running the test suite under valgrind.

have to do:

  local g = G.create ()

ie. give the module your own name ("G" in that example).

3636c5fcff tests: Replace 'make extra-tests' with individual tests.
'make extra-tests' was a monolithic set of tests that did all sorts of
things: valgrind, tests over local guests, tests with upstream qemu,
tests with upstream libvirt, tests with the appliance attach method.

This made it hard to perform individual tests, eg. just valgrind
testing.  It was also hard to maintain because the tests were not
located in the same directories as the programs and sometimes
duplicated tests that were run elsewhere.

This commit splits up 'make extra-tests' into 5 separate targets:

 make check-valgrind              # run a subset of tests under valgrind
 make check-valgrind-local-guests # test under valgrind with local guests
 make check-with-appliance        # test with attach-method == appliance
 make check-with-upstream-qemu    # test with an alternate/upstream qemu
 make check-with-upstream-libvirt # test with an alternate/upstream libvirt

(You can also still run 'make extra-tests' which is now simply
a rule that runs the above 5 targets in order).

This replaces everything that was in the tests/extra directory,
so that has now gone.

a3b6751863 lib: Add new C API calls: guestfs_push_error_handler,
guestfs_pop_error_handler.

The addition of these calls makes it much simpler to temporarily
disable or ignore errors:

 guestfs_push_error_handler (g, NULL, NULL);
 guestfs_mkdir (g, "/foo"); /* We don't care if this fails. */
 guestfs_pop_error_handler (g);

Note these calls are used by the C API only.  They are not necessary
in other languages, because those map errors to exceptions.

The subsequent commits change existing code to use push/pop instead of
laboriously saving and restoring the error handler.

Richard W.M. Jones
1efed122c0 lib: Rework temporary and cache directory code.
New APIs: set-tmpdir, get-tmpdir, set-cachedir, get-cachedir.

The current code has evolved over time and has a number of problems:

(a) A single environment variable ($TMPDIR) controls the
location of several directories.

(b) It's hard for the library user to predict which directory
libguestfs will use, unless the user simulates the same internal steps
that libguestfs performs.

This commit fixes these issues.

(a) Now three environment variables control the location of all small
temporary files, and the appliance cache:

  For temporary files: $LIBGUESTFS_TMPDIR or $TMPDIR or /tmp.

  For the appliance cache: $LIBGUESTFS_CACHEDIR or $TMPDIR or /var/tmp.

The user can also set these directories explicitly through API calls
(guestfs_set_tmpdir and guestfs_set_cachedir).

(b) The user can also retrieve the actual directories that libguestfs
will use, by calling guestfs_get_tmpdir and guestfs_get_cachedir.
These functions are also used internally.

This commit also:

 - reworks the internal tmpdir code

 - removes the internal (undocumented) guestfs_tmpdir call (replacing
   it with calls to the documented guestfs_get_tmpdir API instead)

 - changes the ./run script to set LIBGUESTFS_TMPDIR and
   LIBGUESTFS_CACHEDIR

 - adds a test

 - fixes a few places like libguestfs-make-fixed-appliance which
   depended on $TMPDIR

 - Can redirect output into a callback function.
 - Handles shell quoting properly.
 - Safely resets signal handlers, closes file descriptors, etc.
 - Single place where we can implement other improvements in future.

Richard W.M. Jones
99bd15ad0e generator: Add 'blocking' flag to marking blocking (long-running) functions.
In languages like Python where we release a global lock around
long-running libguestfs functions, it is also useful to *not* release
this lock for small, non-blocking functions.

Therefore mark all functions with a 'blocking' boolean flag.  It
defaults to true, and is true by definition for all daemon functions.
For non-daemon functions, I have classified them manually.

Only when the blocking flag is set do we generate the code to release
and reacquire the lock around libguestfs calls.

Richard W.M. Jones
9466060201 New APIs: guestfs_create_flags, guestfs_parse_environment,
guestfs_parse_environment_list.

Add a new function for creating a handle:

 guestfs_h *guestfs_create_flags (unsigned flags [, ...]);

This variant lets you supply flags and extra arguments, although extra
arguments are not used at the moment.

Of particular interest is the ability to separate the creation of the
handle from the parsing of environment variables like
LIBGUESTFS_DEBUG.  guestfs_create does both together, which prevents
us from propagating errors from parsing environment variables back to
the caller (guestfs_create has always printed any errors on stderr and
then just ignored them).

If you are interested in these errors, you can now write:

 g = guestfs_create_flags (GUESTFS_CREATE_NO_ENVIRONMENT);
 if (!g)
   exit (EXIT_FAILURE);
 r = guestfs_parse_environment (g);
 if (!r)
   exit (EXIT_FAILURE);

Also you can *omit* the call to guestfs_parse_environment, which
creates a handle unaffected by the environment (which was not possible
before).

This commit also includes new (backwards compatible) changes to the
OCaml, Perl, Python, Ruby and Java constructors that let you use the
flags.

d83d17e9db New APIs: Model libvirt authentication events through the API.
This commit models libvirt authentication events through the API,
adding one new event (GUESTFS_EVENT_LIBVIRT_AUTH) and several new
APIs:

  guestfs_set_libvirt_supported_credentials
  guestfs_get_libvirt_requested_credentials
  guestfs_get_libvirt_requested_credential_prompt
  guestfs_get_libvirt_requested_credential_challenge
  guestfs_get_libvirt_requested_credential_defresult
  guestfs_set_libvirt_requested_credential

See the documentation and example which shows how to use the new API.

This commit also changes existing calls to virConnectOpen* within the
library so that the new API is used.

Also included is an example (but not a test, because it's hard to see
how to automatically test the libvirt API).

33f49d85c2 tests: Fix test-qemudie-* so they re-adds the disk on second launch.
Commit ed7fda161e changed the
way that the drives are handled across appliance shutdowns.

Previously during the following sequence of calls:

  create the handle
  add drive(s)
  launch
  kill subprocess
  launch

the added drives are still in the handle at the second launch.

After the above commit, the added drives are removed from the handle,
which means the second launch happens with no drives (which could be
an error).

This was never actually defined either way, so in this case fix the
test to re-add the drive before the second launch.

Since hotplugging was added, it isn't really feasible to return to the
original semantics, since users might remove drives, in which case we
have lost information about those drives so we cannot restore them on
the second launch.

NOTE: PLEASE CALLERS DON'T DO THIS!  Always use a new handle for each
launch of the appliance.

18b7f09f36 Add support for hotplugging (adding disks) to the libvirt attach-method.
When libvirt is used, we can allow disks to be hotplugged.
guestfs_add_drive can be called after launch to hot-add a disk.

When a disk is hot-added, we first ask libvirt to add the disk to the
appliance, then we make an internal call into the appliance to get it
to wait for the disk to appear (ie. udev_settle ()).

Hot-added disks are tracked in the g->drives array.

This also adds a test.

7786d56db8 launch: Add add_drive 'label' option.
New API: list-disk-labels

Allow the user to pass an optional disk label when adding a drive.

This is passed through to qemu / libvirt using the disk serial field,
and from there to the appliance which exposes it through udev,
creating a special alias of the device /dev/disk/guestfs/<label>.
Partitions are named /dev/disk/guestfs/<label><partnum>.

virtio-blk and virtio-scsi limit the serial field to 20 bytes.  We
further limit the name to maximum 20 ASCII characters in [a-zA-Z].

list-devices and list-partitions are not changed: these calls still
return raw block device names.  However a new call, list-disk-labels,
returns a hash table allowing callers to map between disk labels, and
block device and partition names.

This commit also includes a test.

Instead of adding the snapshot=on option via <qemu:arg>, create qcow2
overlays for any read-only drives and the appliance using 'qemu-img
create' + a temporary file.

This is a workaround for missing support for <transient/> in libvirt's
qemu driver.  Also for the unpredictable way that libvirtd handles
$TMPDIR: we want to control where the temporary disk is created.

Currently it is also much slower, because qemu-img is slow.  However
we hope to fix qemu upstream.

6f53d49a27 daemon: When sorting devices, don't fail on mix of /dev/sd and /dev/vd
(RHBZ#858128).

If compare_device_names was given two devices with devices with
different interfaces (eg. /dev/sda and /dev/vda) then it would try to
compare the partition numbers, and fail when it could parse them.

It's arguable what we should be doing in this case (except for
strongly discouraging people from using the interface feature), but
let's at least not cause the daemon to assert-fail.

9ea6e97014 inspection: Fix calls to case_sensitive_path (RHBZ#858126).
Don't assume that if guestfs_case_sensitive_path returns NULL, that it
means the file does not exist.

The (previously undefined) behaviour of case_sensitive_path was that a
NULL return meant "either the file doesn't exist or some other error".
However in commit 973581780d this was
changed so that if the last element of the path didn't exist, it was
assumed to be a new file and the (non-NULL) path of the new file is
returned.

This change breaks code (including in libguestfs) which tries to use
case_sensitive_path as a dual-purpose call to fix-up a path for
Windows and test if the file exists.  Such code should be rewritten so
that it explicitly tests for file existence after calling
case_sensitive_path.

I examined all the calls to case_sensitive_path in libguestfs and
modified them where necessary.

55b7c4df78 virt-edit: If case_sensitive_path returns an error, exit.
The 'windows_path' function was blindly copied from virt-cat.  In
virt-cat, errors are checked by the caller to 'windows_path'.  But
virt-edit lacks this check.  Change the function in virt-edit to add a
check and exit on error.

There's not really any point just documenting that people

However it's not a failure if chcon doesn't work.  If SELinux
is not installed or is disabled, then labelling will fail.

763ec36cf0 Update SuSE Linux detection.
Update SuSE Linux detection. Up to now everything with a
/etc/SuSE-release file was treated as openSuSE. With this change SLES
based distributions such as "SUSE Linux Enterprise Server", "SUSE
Linux Enterprise Desktop" and "Novell Linux Desktop" will show up as
"sles". The 'opensuse' detection was updated to handle older openSuSE
releases as well as the well known SuSE Linux releases, starting from
6.0. Everything else with a /etc/SuSE-release file will show up as
"suse-based".

aa9e0057b1 launch: libvirt: Mark appliance disk as <shareable/> (thanks Dan Berrange).
This is a fix for multiprogramming: If two instances of libguestfs
share the same appliance disk, then libvirt would unlabel the disk
when one of the instances closes the handle, resulting in the other
qemu being unable to continue accessing the appliance.

Adding the flag makes libvirt understand that the disk is shared so it
doesn't do this, and it apparently handles locking correctly too if we
were using sanlock.

8248a346d7 proto: Don't set g->fd[] to /dev/null in direct mode, fixing virt-rescue (RHBZ#853159).
https://bugzilla.redhat.com/show_bug.cgi?id=853159

git bisect pointed to the following commit:

  commit ec8e3b6cad
  Author: Richard W.M. Jones <rjones@redhat.com>
  Date:   Fri Jul 20 14:24:10 2012 +0100

    launch: Abstract attach method operations.

    g->attach_ops points to a structure which contains the
    operations supported by each attach method backend
    (ie. appliance, unix, etc.).

Since that commit was essentially just code motion, it wasn't clear
why virt-rescue should be affected by it.

In fact the reason is as follows:

(1) In direct mode, we don't need g->fd[] (which would normally be
connected to the stdin/stdout of qemu).  So we opened them on
/dev/null so they had some value.

(2) accept_from_daemon / read_log_message_or_eof reads from g->fd[1].
Since this is connected to /dev/null, it always reads EOF.

(3) This would cause child_cleanup to be called.  This is completely
unintentional: we don't want to cleanup the child at this point, even
in direct mode.

(4) Prior to the commit above, child_cleanup first waited for the
process to exit (ie. waitpid).  This happened to work, since we are
effectively waiting for the user to exit virt-rescue.

(5) After the commit above, the order of operations was changed so
that we first killed qemu before waiting for it.  This broke
virt-rescue.

The fix is to change direct mode so that it leaves g->fd[]'s as -1.
The rest of the protocol code can deal with this situation -- it
ignores the log fd instead of trying to read from it.

2e36adf83c rescue: If attach-method is 'libvirt', force it to be 'appliance'.

6fdf1f40fa rescue: If -v / debugging enabled, don't mask error messages.
We set the error handler to NULL in order to mask "normal" error
messages that we expect to see because of the unusual way that
virt-rescue runs the appliance.  However if the user selected -v /
enabled debugging, then it is reasonable to expect they want to see
every message, so do not mask anything.

GUESTFSD_EXT_CMD(C_variable, command_name);

This syntax makes it still possible to grep for used command names.

The actual usage of the collected list could be like this:

  objcopy -j .guestfsd_ext_cmds -O binary daemon/guestfsd /dev/stdout |
  tr '\0' '\n' | sort -u

The resulting output will be used to tell mkinitrd which programs to

8a723ca62e New APIs: hivex_*
Transscribe many hivex(3) APIs into the libguestfs API.

There is one hive handle per libguestfs handle, as with Augeas.

Note that hivex uses iconv_open for some APIs (eg. hivex_value_string).
But since we delete all the i18n files from the appliance, this
doesn't work -- iconv_open returns EINVAL.  Therefore hivex APIs which
require iconv cannot be bound in the daemon.

228d49bb84 lib: Remove AUGEAS_CFLAGS, AUGEAS_LIBS.

044c5b26d7 remove ulockmgr from fuse LDFLAGS
libguestfs fails to build with --enable-fuse on openSuSE 11.4 and
earlier because the included fuse version does not include
libulockmgr.so. configure already used pkgconfig to retrieve the correct
CFLAGS, so there is no need to hardcode -lulockmgr.
With this change the build succeeds again.

863168467f examples: Use add_drive_opts function in examples.
In libguestfs 1.20, you will be able to use 'add_drive'
instead of 'add_drive_opts' (except in the C bindings).

However until libguestfs 1.20 is the minimum stable version
people will still be using old versions where you have to use
'add_drive_opts'.  This makes the examples confusing.

Therefore continue to use 'add_drive_opts' in the examples
for now.

d8b2c1afee umount: use Dev_or_Path for the argument type
Use Dev_or_Path instead of String.

Remove the RESOLVE_DEVICE since Dev_or_Path will generate
REQUIRE_ROOT_OR_RESOLVE_DEVICE instead.

RWMJ:
Note a change in semantics: this now requires root.  However this is
OK and still works with mkmountpoint and friends because
'is_root_mounted' works even if something is mounted below the root.

 - config: deprecated API which fiddles with the qemu command
   line directly

 - max-disks: depends on the qemu implementation (virtio-scsi
   or not)

 - debug-drives: used for testing only

launch-unix.c contains the code associated with 'unix:<path>'.

launch.c is the common code for launching, along with a few other APIs
such as guestfs_add_drive_opts.

50780a84f6 tar-in: Add --no-same-owner flag to tar command when target filesystem doesn't support chown (RHBZ#840572).
When using tar-in or tools built around it such as virt-make-fs, if
the target filesystem is vfat then unpacking the tarball would fail
because tar tries to chown(2) files and fails.

You would see errors such as:

tar: <file>: Cannot change ownership to uid 500, gid 500: Operation not permitted

This change detects whether the target filesystem supports chown(2).
If not, it adds the --no-same-owner flag to tar to stop it from trying
to change the ownership of newly created files.

This commit changes some of the non-C bindings so that they also
generate 'func_opts' which is merely a wrapper that calls 'func'.

This avoids incompatibility when we rename 'mkfs_opts' etc back to
plain 'mkfs', and it also makes it easier to translate between other
language bindings and C code.

NB: Some bindings do not include aliases:

  PHP:     There's no way to easily alias methods in PHP < 5.3, and we
           can't assume everyone has this minimum version.

  GObject: Very complex to add aliases, but we should probably do this
           at some point.

  Haskell: No support for optargs in these bindings.  Unfortunately
           this means that we can no longer bind 'Guestfs.add_drive'
           (since it will be changed to add optional arguments) making
           the Haskell bindings even less useful than they were already.

98757e151a generator: Allow non-optargs functions to gain optargs.
This commit adds a flag (once_had_no_optargs) which can be used to add
optargs to functions that currently don't have any.

The idea is that if 'func' currently has no optargs, we can safely add
optargs provided we are backwards compatible for existing callers.

In C that means we leave 'guestfs_func' alone and provide an extra
function 'guestfs_func_opts' that takes the optargs ('guestfs_func'
becomes a wrapper that calls 'guestfs_func_opts').

In the C generator this means there are two names for each function
(although the two names are normally identical).  'c_name' is the name
that we export publicly (eg. [guestfs_] 'func_opts').  'name' is the
internal name of the function (eg. 'func') which is used for
everything apart from the public interface, and also to generate the
no-optargs compat function.

In other languages that can add optional arguments safely, we simply
add the arguments to the existing 'func', so for example in Perl:

  $g->func (required_args)
  $g->func (required_args, optional_args)

can be used.

Note that this commit does not cause any change to the output of the
generator.  I verified this by diffing the output before and after.

is now accompanied by this overloaded method which is a simple wrapper:

  public void mkfs_opts (String fstype, String device)
    throws LibGuestFSException
  {
    mkfs_opts (fstype, device, null);

Richard W.M. Jones
9286f556c6 generator: Add c_function (C function name) to each action struct.
This field, which is generated internally by the generator, is the
name of the C function corresponding to each action.

For actions that have NO optional arguments, it's just "guestfs_<name>".

For actions that have any optional arguments, it is
"guestfs_<name>_argv" (since any binding has to construct the optional
argument struct explicitly).

In a future commit, this mapping may become more complex.

This commit also "fixes" the C# bindings which didn't handle optional
arguments properly at all.  In fact, it doesn't fix this, it just
changes it enough that it probably now compiles.  We should either
compile and test the bindings routinely with Mono, or drop them, since
they are starting to bit-rot.

In the GObject bindings, I have added a space between the C function
name and the first paren.

Apart from the C# and GObject changes, this is just code motion.  It
was verified by diffing the output of the generator before and after.

39d1a7dbc9 generator: Use a struct instead of a tuple to describe each action.
Each action changes from a tuple like this:

  ("cat", (RString "content", [Pathname "path"], []), 4,
   [ProtocolLimitWarning],
   [InitISOFS, Always, TestOutput (
      [["cat"; "/known-2"]], "abcdef\n")],
   "list the contents of a file",
   "[...]");

to a slightly longer but more readable struct:

  { defaults with
    name = "cat";
    style = RString "content", [Pathname "path"], [];
    proc_nr = Some 4;
    protocol_limit_warning = true;
    tests = [
      InitISOFS, Always, TestOutput (
      [["cat"; "/known-2"]], "abcdef\n")
    ];
    shortdesc = "list the contents of a file";
    longdesc = "[...]" };

["defaults" is a struct which contains the defaults for every field,
allowing us to use the "{ defaults with ... }" syntax to just update
the fields we want to be different from the defaults.]

This is a mechanical change and there is no change to the output of
the generator.  I checked the output before and after with diff to
verify this.  There are no changes in the output apart from UUIDs
which are expected to change with each run.

ffbf1475f7 New API: guestfs_shutdown: Cleanly shutdown the backend.
The new API splits orderly close into a two-step process:

  if (guestfs_shutdown (g) == -1) {
    /* handle the error, eg. qemu error */
  }
  guestfs_close (g);

Note that the explicit shutdown step is only necessary in the case
where you have made changes to the disk image and want to handle write
errors.  Read the documentation for further information.

This change also:

 - deprecates guestfs_kill_subprocess

 - turns guestfs_kill_subprocess into the same as guestfs_shutdown

 - changes guestfish and other tools to call shutdown + close
   where necessary (not for read-only tools)

 - updates documentation

 - updates examples

c0a3c9ce70 daemon: Run fsync on block devices after sync (RHBZ#836710).
On Linux, sync(2) does not actually issue a write barrier, thus it
doesn't force a flush of the underlying hardware write cache (or
qemu's disk cache in the virtual case).

This can be a problem, because libguestfs relies on running sync in
the appliance, followed by killing qemu (using SIGTERM).

In most cases, this is fine, because killing qemu with SIGTERM should
cause it to flush out the disk cache before it exits.  However we have
found various bugs in qemu which cause qemu to crash while doing the
flush, leaving the data unwritten (see RHBZ#836913).

The solution is to issue fsync(2) to the block devices.  This has a
write barrier, so it ensures that qemu writes out its cache long
before we get around to killing qemu.

c87956837e launch: Avoid double-close when qemu exits early.
The stdin and stdout of the qemu process are aliased to g->fd:

  g->fd[0] = wfd[1];
  g->fd[1] = rfd[0];

However if the child exits early, then child_cleanup closes g->fd[0],
g->fd[1], AND the code at the cleanup1 label closes wfd[1], rfd[0],
resulting in a double-close.

Avoid this case by setting wfd[1], rfd[0] to -1.  In the cleanup1
label, only close wfd[1], rfd[0] if they are not -1, and add the same
for g->fd[0], g->fd[1].

Old KVM can't add /dev/null readonly.  Treat /dev/null as a special
case.

We also fix a few tests where /dev/null was being used with
format=qcow2.  This was always incorrect behaviour, but qemu appears
to tolerate it.

461455ca7c tests/xml: Fix compilation of test on RHEL 5 with old libvirt.
Old <libvirt.h> had a conflicting definition of virDomainGetXMLDesc:

fake_libvirt_xml.c:36: error: conflicting types for 'virDomainGetXMLDesc'
/usr/include/libvirt/libvirt.h:715: error: previous declaration of 'virDomainGetXMLDesc' was here

The difference is not material ('int' vs. 'unsigned int').

Avoid the error by not including <libvirt.h>.

50aa9533e4 build: Define builddir and abs_srcdir when they are missing.
RHEL 5-era autoconf did not define these, so define them manually
when they are missing.

Define builddir as '.'  The scripts require this.  It won't work
in the srcdir != builddir case, but we don't care about that for
RHEL 5.

This commit also moves the builddir / abs_srcdir variable setting
above the include of subdir-rules.mk, in case that include uses
these variables.

Useful script:

  for f in $(find -name Makefile.am | xargs fgrep '$(abs_srcdir)' -l) ; do
    if ! grep -q '^abs_srcdir' $f; then
      echo missing in $f

62c5b6db58 daemon: Always pass -F option to mke2fs.
Apparently e2fsprogs only knows that "/dev/sda" is a whole device, but
doesn't think that "/dev/vda" is.  On switching the default device
over to virtio-scsi, that causes mke2fs without -F option to complain
and ask for an interactive prompt.  Adding -F forces it to go ahead
anyway.

This caused several less-used APIs to break with virtio-scsi.

7652b5aece Remove ./configure --with-drive-if and --with-net-if options.
These were used to select the default drive and network interface.
They both default to 'virtio'.

These were added back in the day when virtio was buggy, so that
packagers could revert to using ide/ne2k_pci to work around distro
bugs.  However virtio has been stable in qemu for a very long time, so
it seems unlikely that any packager would need to use these, and in
any case it would be better to do this detection at runtime (cf. for
virtio-scsi).

20137c8731 fish: Change test-escapes so test is not endian-sensitive.
The test used the external 'od' command to compare the output of
guestfish with what it's supposed to be.  Unfortunately by default
this outputs groups of 2-byte words, with the words' endianness
affected by the current hardware endianness.  For example:

x86-64$ echo -n ab | od
0000000 061141
0000002

ppc64$ echo -n ab | od
0000000 060542
0000002

By using 'od -b' instead we can output bytes instead of words, and
there is no endianness issue, and the output is clearer:

x86-64$ echo -n ab | od -b
0000000 141 142
0000002

ppc64$ echo -n ab | od -b
0000000 141 142

f90c01a5dc Enhance BUGS script.
Since RHBZ was updated, the old python-bugzilla program broke.  When

the old tool was no longer true.

This commit adds a small Perl script to sort the output predictably.
Now bugs are sorted by both bug state and bug number, so the output
should be more stable than before.

Re-enable creation of the BUGS file in 'make dist'

f00066d22b inspection: Don't fail if /etc/HOSTNAME or /etc/hostname are empty files (RHBZ#823821).
Change guestfs___first_line_of_file so that if the file is empty this
returns an empty string instead of an error.  This is consistent with
the behaviour of this function in the case where the file starts with
a \n character, where it would previously have returned an empty
string.

Change all callers so that they handle this case.

Then change the hostname parsing code so that it doesn't give up when
/etc/HOSTNAME is empty, but falls through to the next alternative, and
similarly for /etc/hostname.

[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.

- getfacl, getfattr libraries and programs (optional)
- netpbm, icoutils (optional)
These programs are used to render icons from guests.

* Allow alternate methods to start the appliance, including through
libvirt, by connecting to an existing appliance, and remotely over

* Write a new partition handling library to replace parted, and use it

this approach works, it doesn't solve the MBR problem, so likely we'd

qemu caching
------------
(Suggested by Paolo Bonzini and Kevin Wolf)
Measure the effect of cache=none, cache=directsync,
cache=writethrough, cache=writeback.
It's doubtful that using cache=none is useful, since it disables the
host cache making read-heavy workloads slower (they rely entirely on
the smaller appliance kernel's cache). And in libguestfs we don't
necessarily care about ongoing data integrity while writing, as long
as data is reliably written out when g.sync, g.shutdown or g.close
return. Also in libguestfs we effectively control the whole stack, so
we can ensure write barriers happen when we want.
libvirt backend
---------------
Since libguestfs 1.19.24 this mostly works. Here are some suggested
items to work on:
- SELinux labelling of guestfsd.sock, console.sock
https://bugzilla.redhat.com/show_bug.cgi?id=842307
Once this is fixed, remove <seclabel type=none> from libvirt XML
- Check feature parity between src/launch-appliance.c and
src/launch-libvirt.c.
- Remote support. (This requires work on libvirt)
virt-sparsify should use discard
--------------------------------
This requires some changes to qemu to make discard work properly
throughout the entire stack.
Reimplement some APIs to avoid protocol limits
----------------------------------------------
We should reimplement the following APIs to avoid protocol limits.
These would be changed from daemon_functions to non_daemon_functions,
with the non-daemon versions implemented using guestfs_upload and
guestfs_download (and others). This change should be transparent from
the p.o.v of the API and ABI.
- guestfs_readdir
hivex
-----
Add more of hivex to the API, especially for writing.
Reimplement virt-win-reg to use this API. (This is difficult because
the Perl libraries underneath access the hivex API directly).
ruby
----
Implement blocking calls. The API for this:
http://www.spacevatican.org/2012/7/5/whos-afraid-of-the-big-bad-lock/
is very poorly designed and essentially impossible for us to use:
https://bugs.ruby-lang.org/issues/5543
particularly if we also want to maintain backwards compatibility with
Ruby 1.8, and/or maintain volatile VALUEs on the stack.

Since libguestfs 1.22, virt-alignment-scan is multithreaded and
examines guests in parallel. By default the number of threads to use
is chosen based on the amount of free memory available at the time
that virt-alignment-scan is started. You can force

=head1 NAME
guestfsd - guestfs daemon
=head1 SYNOPSIS
guestfsd [-r] [-v|--verbose]
=head1 DESCRIPTION
C<guestfsd> is the libguestfs daemon. Normal users never need to run
this program explicitly. This man page discusses what C<guestfsd>
does in both the libguestfs appliance and when using libguestfs live.
=head2 LIBGUESTFS APPLIANCE
For the architecture of the libguestfs appliance, see
L<guestfs(3)/ARCHITECTURE>.
After the appliance boots, the C</init> script in the appliance starts
C<guestfsd> with no arguments. C<guestfsd> opens the virtio-serial
port on a known path (see L</FILES>). It initiates the protocol (see
L<guestfs(3)/COMMUNICATION PROTOCOL>) and processes requests one at a
time from the library until the appliance is destroyed.
Filesystems are mounted under C</sysroot> and all filesystem
operations happen relative to this directory.
=head2 LIBGUESTFS LIVE
In the libguestfs live case, C<guestfsd -r> is started from the
rc-scripts, systemd, etc.
The C<-r> option causes the daemon to operate on the root filesystem
instead of C</sysroot>.
Currently (because of limitations in virtio-serial) only one client
can connect at a time, and C<guestfsd> must be restarted after each
client disconnects. If libguestfs live were changed to use a
different transport such as TCP/IP then this limitation could be
removed.
=head1 OPTIONS
=over 4
=item B<-?>
=item B<--help>
Display brief help.
=item B<-r>
Set the root filesystem to be C</> (instead of the default which is
C</sysroot>). Also do not unmount filesystems when the daemon exits.
This option is used to enable libguestfs live.
=item B<-v>
=item B<--verbose>
Enable verbose messages for debugging.
The verbose flag is also set if the Linux command line contains the
substring C<guestfs_verbose=1>.
=back
=head1 EXIT STATUS
This program returns 0 if successful, or non-zero if there was an
error.
=head1 FILES
=over 4
=item C</dev/virtio-ports/org.libguestfs.channel.0>
The virtio serial port which C<guestfsd> connects to.
=item C</proc/cmdline>
The Linux command line is parsed to discover C<guestfs_*> flags.
