Add the new API btrfs-fsck to check the btrfs filesystem.
Btrfs is currently under heavy development, and not suitable for
any uses other than benchmarking and review. But it'll be useful
in the near future.

This flag allows extra QEMU options to be passed on the command line.
This is useful mainly on arm (see the notes in the updated README
file).

Presently KVM is only applicable to x86 and x86-64 (although that will
change in future, and there are rumoured to be implementations for
some current non-x86 architectures). In any case having these options
breaks ARM, so disable them for non-x86 architectures at the moment.

For ARM Versatile ("versatilepb") architecture, memsize must be set to
256 (megabytes) else the appliance is unable to boot. Previously
setting LIBGUESTFS_MEMSIZE=256 was not allowed.
Versatile Express has larger limits.

'./configure --disable-probes' will disable these probes. Otherwise
they are autodetected as before.
The <sys/sdt.h> produces lots of errors when you try to compile with
these probes enabled under clang, so it is necessary to provide a way
to disable them for clang users.

Make the introduction in the man page shorter and punchier, so it
leads readers directly to other pages of interest.

gettextize provides a local file called "gettext.h". Remove this and
use <libintl.h> from glibc headers instead.
Most of this change is mechanical: #include <libintl.h> in every C
file which uses any gettext function. But also we remove the
gettext.h file, and adjust the "_" macros.
Note that this effectively removes the ./configure --disable-nls
option, although we don't know if that ever worked.

Since it describes the C library, it's better in the src/ directory.

Originally this state was intended so that in some way you could find
out if the appliance was running a command. However there was never a
thread-safe way to access the state of the handle, so in effect you
could never do anything useful safely with this information.
This commit completely removes the BUSY state.
The only visible change is to the guestfs_is_busy API. Previously you
could never call this safely from another thread. If you called it
from the same thread it would always return false (since the current
thread can't be running a libguestfs command at that point by
definition). Now it always returns false.

Bind the easy parts of the 'btrfs' program.
The new APIs are:
btrfs-device-add: add devices to a btrfs filesystem
btrfs-device-delete: remove devices from a btrfs filesystem
btrfs-filesystem-sync: sync a btrfs filesystem
btrfs-filesystem-balance: balance a btrfs filesystem
btrfs-subvolume-create: create a btrfs snapshot
btrfs-subvolume-delete: delete a btrfs snapshot
btrfs-subvolume-list: list btrfs snapshots and subvolumes
btrfs-subvolume-set-default: set default btrfs subvolume
btrfs-subvolume-snapshot: create a writable btrfs snapshot

The new APIs are:
get-e2attrs: List ext2 file attributes of a file.
set-e2attrs: Set or clear ext2 file attributes of a file.
get-e2generation: Get ext2 file generation of a file.
set-e2generation: Set ext2 file generation of a file.
These are implemented using the lsattr and chattr programs from
e2fsprogs.

Remove the bogus check_path function and move the functionality into
the two places where it was being used.
qemu -cdrom ,
works fine, I tested it.
Colon cannot be used in a block device filename anywhere, since the
qemu block driver interprets it as a prefix. There is no known way to
work around this problem. I checked this is true with kwolf.
Comma is fine in -drive options, provided it is escaped by doubling it.

guestfs(3) man page.
Inexplicably these were not included before.
|
| |
|
|
|
| |
This caused the Python bindings (and probably others) to
segfault because guestfs_last_error(g) would return NULL.
|
| |
|
|
|
| |
But ignore it if the call fails, since the file descriptor could be a
non-file (eg. /dev/stdout).

Add FUSE support directly to the API. Instead of needing to use the
external 'guestmount' command, you can mount the libguestfs filesystem
space on a local mountpoint using an API call from any language.
Note that although mount-local-run is marked as Cancellable, the
current implementation does not support it, but it would be relatively
simple to add it.

Unclear if this is a real bug or not.

Previously there was no programmatic way to tell if inspection APIs
were unavailable because they are not compiled in (because hivex isn't
around). This contrasts with daemon APIs where the availability is
covered by the guestfs_available API.
Change the inspection APIs so that when they are not available, the
last errno is set to ENOTSUP. (Note that ENOTSUP must be defined on
all POSIX platforms).
This allows programs to detect if they are using a version of
libguestfs that was compiled without support for inspection, without
having to parse error messages.

Add an API for doing what virt-sparsify was doing: freeing up free
space in a filesystem.
The current implementation is simple-minded: we create a file, fill it
with zeroes until we run out of space, then delete the file. However
the description leaves it open to do a better implementation, eg.
using sparsification support that is currently being worked on in ext4
and qemu.
The implementation also sends progress notifications, which is an
advantage over the old 'dd' method.

When a Windows guest doesn't have a HKLM\SYSTEM\MountedDevices node,
inspection fails. However inspection should not completely fail just
because we cannot get the drive letter mapping from a guest.

The presumption is that all file descriptors should be created with
the close-on-exec flag set. The only exception are file descriptors
that we want passed through to exec'd subprocesses (mainly pipes and
stdin/stdout/stderr).
For open calls, we pass O_CLOEXEC as an extra flag, eg:
fd = open ("foo", O_RDONLY|O_CLOEXEC);
This is a Linux-ism, but using a macro we can easily make it portable.
For sockets, similarly:
sock = socket (..., SOCK_STREAM|SOCK_CLOEXEC, ...);
For accepted sockets, we use the Linux accept4 system call which
allows flags to be supplied, but we use the Gnulib 'accept4' module to
make this portable.
For dup, dup2, we use the Linux dup3 system call, and the Gnulib
modules 'dup3' and 'cloexec'.

Analyze all uses of 'int' in the code, and replace with 'size_t' where
appropriate.
|
| |
|
|
|
|
|
|
| |
In two places, we were counting things in an array using an 'int'. In
theory, the int could overflow, so gcc determines this to be undefined
behaviour.
The fix is to use size_t or ssize_t instead.
