Include locale.h for setlocale().
Revert the usage string back to it's original form.
Use puts() instead of fputs(), as fputs() expects a FILE*.
Add closing parenthesis to some vah_error() calls.
Use argv[0] instead of an undefined argv0.
These messages are visible to the user, so they should be
consistently translated.
* cfg.mk (msg_gen_function): Add vah_error, vah_warning.
* src/security/virt-aa-helper.c: Translate messages.
(catchXMLError): Fix capitalization.
Per the gettext developer:
http://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00019.htmlhttp://lists.gnu.org/archive/html/bug-gnu-utils/2010-10/msg00021.html
gettext() doesn't work correctly on all platforms unless you have
called setlocale(). Furthermore, gnulib's gettext.h has provisions
for setting up a default locale, which is the preferred method for
libraries to use gettext without having to call textdomain() and
override the main program's default domain (virInitialize already
calls bindtextdomain(), but this is insufficient without the
setlocale() added in this patch; and a redundant bindtextdomain()
in this patch doesn't hurt, but serves as a good example for other
packages that need to bind a second translation domain).
This patch is needed to silence a new gnulib 'make syntax-check'
rule in the next patch.
* daemon/libvirtd.c (main): Setup locale and gettext.
* src/lxc/lxc_controller.c (main): Likewise.
* src/security/virt-aa-helper.c (main): Likewise.
* src/storage/parthelper.c (main): Likewise.
* tools/virsh.c (main): Fix exit status.
* src/internal.h (DEFAULT_TEXT_DOMAIN): Define, for gettext.h.
(_): Simplify definition accordingly.
* po/POTFILES.in: Add src/storage/parthelper.c.
When <uuid> is not in the XML, a virUUIDGenerate() ends up being called which
is unnecessary and can lead to crashes if /dev/urandom isn't available
because virRandomInitialize() is not called within virt-aa-helper. This patch
adds verify_xpath_context() and updates caps_mockup() to use it.

Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
Description: Implement AppArmorSetSecurityHostdevLabel() and
AppArmorRestoreSecurityHostdevLabel() for hostdev and pcidev attach.
virt-aa-helper also has to be adjusted because *FileIterate() is used for pci
and usb devices and the corresponding XML for hot attached hostdev and pcidev
is not in the XML passed to virt-aa-helper. The new '-F filename' option is
added to append a rule to the profile as opposed to the existing '-f
filename', which rewrites the libvirt-<uuid>.files file anew. This new '-F'
option will append a rule to an existing libvirt-<uuid>.files if it exists,
otherwise it acts the same as '-f'.
load_profile() and reload_profile() have been adjusted to add an 'append'
argument, which when true will use '-F' instead of '-f' when executing
virt-aa-helper.
All existing calls to load_profile() and reload_profile() have been adjusted
to use the old behavior (ie append==false) except AppArmorSetSavedStateLabel()
where it made sense to use the new behavior.
This patch also adds tests for '-F'.

Commit 68719c4bdd added the
p option to control disk format probing, but it wasn't added
to the getopt_long optstring parameter.
Add the p option to the getopt_long optstring parameter.
Commit a885334499 added this
function and wrapped vah_add_file in it. vah_add_file may
return -1, 0, 1. It returns 1 in case the call to valid_path
detects a restricted file. The original code treated a return
value != 0 as error. The refactored code treats a return
value < 0 as error. This triggers segfault in virt-aa-helper
and breaks virt-aa-helper-test for the restricted file tests.
Make sure that add_file_path returns -1 on error.
virt-aa-helper used to ignore errors when opening files.
Commit a885334499 refactored
the related code and changed this behavior. virt-aa-helper
didn't ignore open errors anymore and virt-aa-helper-test
fails.
Make sure that virt-aa-helper ignores open errors again.
Disk format probing is now disabled by default. A new config
option in /etc/qemu/qemu.conf will re-enable it for existing
deployments where this causes trouble
Update the QEMU cgroups code, QEMU DAC security driver, SELinux
and AppArmour security drivers over to use the shared helper API
virDomainDiskDefForeachPath().
* src/qemu/qemu_driver.c, src/qemu/qemu_security_dac.c,
src/security/security_selinux.c, src/security/virt-aa-helper.c:
Convert over to use virDomainDiskDefForeachPath()
Require the disk image to be passed into virStorageFileGetMetadata.
If this is set to VIR_STORAGE_FILE_AUTO, then the format will be
resolved using probing. This makes it easier to control when
probing will be used
* src/qemu/qemu_driver.c, src/qemu/qemu_security_dac.c,
src/security/security_selinux.c, src/security/virt-aa-helper.c:
Set VIR_STORAGE_FILE_AUTO when calling virStorageFileGetMetadata.
* src/storage/storage_backend_fs.c: Probe for disk format before
calling virStorageFileGetMetadata.
* src/util/storage_file.h, src/util/storage_file.c: Remove format
from virStorageFileMeta struct & require it to be passed into
method.
Do not require each caller of virStorageFileGetMetadata and
virStorageFileGetMetadataFromFD to first clear the storage of the
"meta" buffer. Instead, initialize that storage in
virStorageFileGetMetadataFromFD.
* src/util/storage_file.c (virStorageFileGetMetadataFromFD): Clear
"meta" here, not before each of the following callers.
* src/qemu/qemu_driver.c (qemuSetupDiskCgroup): Don't clear "meta" here.
(qemuTeardownDiskCgroup): Likewise.
* src/qemu/qemu_security_dac.c (qemuSecurityDACSetSecurityImageLabel):
Likewise.
* src/security/security_selinux.c (SELinuxSetSecurityImageLabel):
Likewise.
* src/security/virt-aa-helper.c (get_files): Likewise.
* src/security/virt-aa-helper.c: adjust virt-aa-helper to handle pci
devices. Update valid_path() to have an override array to check against,
and add "/sys/devices/pci" to it. Then rename file_iterate_cb() to
file_iterate_hostdev_cb() and create file_iterate_pci_cb() based on it
To avoid an error when hitting the <seclabel...> definition
* src/security/virt-aa-helper.c: add VIR_DOMAIN_XML_INACTIVE flag
to virDomainDefParseString
Don't exit with error if the user unloaded the profile outside of
libvirt
* src/security/virt-aa-helper.c: check the exit error from apparmor_parser
before exiting with a failure

Added support for product/vendor based passthrough, but it only
worked at the security driver layer. The main guest XML config
was not updated with the resolved bus/device ID. When the QEMU
argv refactoring removed use of product/vendor, this then broke
launching guests.
THe solution is to move the product/vendor resolution up a layer
into the QEMU driver. So the first thing QEMU does is resolve
the product/vendor to a bus/device and updates the XML config
with this info. The rest of the code, including security drivers
and QEMU argv generated can now rely on bus/device always being
set.
* src/util/hostusb.c, src/util/hostusb.h: Split vendor/product
resolution code out of usbGetDevice and into usbFindDevice.
Add accessors for bus/device ID
* src/security/virt-aa-helper.c, src/security/security_selinux.c,
src/qemu/qemu_security_dac.c: Remove vendor/product from the
usbGetDevice() calls
* src/qemu/qemu_driver.c: Use usbFindDevice to resolve vendor/product
into a bus/device ID
Based off how QEMU does it, look through /sys/bus/usb/devices/* for
matching vendor:product info, and if found, use info from the surrounding
files to build the device's /dev/bus/usb path.
This fixes USB device assignment by vendor:product when running qemu
as non-root (well, it should, but for some reason I couldn't reproduce
the failure people are seeing in [1], but it appears to work properly)

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.

* src/security/virt-aa-helper.c: suppress confusing and misleading
apparmor denied message when kvm/qemu tries to open a libvirt specified
readonly file (such as a cdrom) with write permissions. libvirt uses
the readonly attribute for the security driver only, and has no way
of telling kvm/qemu that the device should be opened readonly
Fixes https://launchpad.net/bugs/460271
* src/security/virt-aa-helper.c: require absolute path for dynamic added
files. This is required by AppArmor and conveniently prevents adding
tcp consoles to the profile
* src/security/virt-aa-helper.c: get_definition() now calls the new
caps_mockup() function which will parse the XML for os.type,
os.type.arch and then sets the wordsize. These attributes are needed
only to get a valid virCapsPtr for virDomainDefParseString(). The -H
and -b options are now removed from virt-aa-helper (they weren't used
yet anyway).
* tests/virt-aa-helper-test: extend and fixes tests, chmod'ed 755
* configure.in: look for AppArmor and devel
* src/security/security_apparmor.[ch] src/security/security_driver.c
src/Makefile.am: add and plug the new driver
* src/security/virt-aa-helper.c: new binary which is used exclusively by
the AppArmor security driver to manipulate AppArmor.
* po/POTFILES.in: registers the new files
* tests/Makefile.am tests/secaatest.c tests/virt-aa-helper-test:
tests for virt-aa-helper and the security driver, secaatest.c is
identical to seclabeltest.c except it initializes the 'apparmor'
driver instead of 'selinux'
