[libvirt] [PATCH libvirt-java 1/2] Return a byte[] array with secretGetValue
by Wido den Hollander 05 Jul '12

05 Jul '12

We break the API with this, but Java does not support multiple method signatures with different return types. The old method returned a String, but since a secret can be binary data this type is not suited. Users who now that their secret is in fact a String, can use cast with: Secret secret = conn.secretLookupByUUIDString("uuuuuuuid"); String value = new String(secret.getValue()); Signed-off-by: Wido den Hollander <wido(a)widodh.nl> --- src/main/java/org/libvirt/Secret.java | 13 ++++++++++--- src/main/java/org/libvirt/jna/Libvirt.java | 2 +- 2 files changed, 11 insertions(+), 4 deletions(-) diff --git a/src/main/java/org/libvirt/Secret.java b/src/main/java/org/libvirt/Secret.java index 48f7895..39d9122 100644 --- a/src/main/java/org/libvirt/Secret.java +++ b/src/main/java/org/libvirt/Secret.java @@ -5,6 +5,9 @@ import org.libvirt.jna.SecretPointer; import com.sun.jna.Native; import com.sun.jna.NativeLong; +import com.sun.jna.ptr.LongByReference; +import com.sun.jna.Pointer; +import java.nio.ByteBuffer; /** * A secret defined by libvirt @@ -106,12 +109,16 @@ public class Secret { /** * Fetches the value of the secret - * + * * @return the value of the secret, or null on failure. */ - public String getValue() throws LibvirtException { - String returnValue = libvirt.virSecretGetValue(VSP, new NativeLong(), 0); + public byte[] getValue() throws LibvirtException { + LongByReference value_size = new LongByReference(); + Pointer value = libvirt.virSecretGetValue(VSP, value_size, 0); processError(); + ByteBuffer bb = value.getByteBuffer(0, value_size.getValue()); + byte[] returnValue = new byte[bb.remaining()]; + bb.get(returnValue); return returnValue; } diff --git a/src/main/java/org/libvirt/jna/Libvirt.java b/src/main/java/org/libvirt/jna/Libvirt.java index b1e53a2..f53199d 100644 --- a/src/main/java/org/libvirt/jna/Libvirt.java +++ b/src/main/java/org/libvirt/jna/Libvirt.java @@ -330,7 +330,7 @@ public interface Libvirt extends Library { public int virSecretGetUUID(SecretPointer virSecretPtr, byte[] uuidString); public int virSecretGetUUIDString(SecretPointer virSecretPtr, byte[] uuidString); public String virSecretGetUsageID(SecretPointer virSecretPtr); - public String virSecretGetValue(SecretPointer virSecretPtr, NativeLong value_size, int flags); + public Pointer virSecretGetValue(SecretPointer virSecretPtr, LongByReference value_size, int flags); public String virSecretGetXMLDesc(SecretPointer virSecretPtr, int flags); public SecretPointer virSecretLookupByUsage(ConnectionPointer virConnectPtr, int usageType, String usageID); public SecretPointer virSecretLookupByUUID(ConnectionPointer virConnectPtr, byte[] uuidBytes); -- 1.7.9.5

[libvirt] [PATCH] qemu: Always set auth_supported for Ceph disks.
by Wido den Hollander 05 Jul '12

05 Jul '12

Recently the Ceph project defaulted auth_supported from 'none' to 'cephx'. When no auth information was set for Ceph disks this would lead to librados defaulting to 'cephx', but there would be no additional authorization information. We now explicitly set auth_supported to none when passing down arguments to Qemu.

[libvirt] sanlock on F17
by Dave Allan 02 Jul '12

02 Jul '12

I just tried to set up sanlock on F17 using the instructions at http://libvirt.org/locking.html, but libvirtd refuses to start with the sanlock error in the logs: Jun 29 19:56:20 nienna sanlock[8423]: 19846 open error -13 /var/lib/libvirt/sanlock/__LIBVIRT__DISKS__ I confirmed that user sanlock can create, read and write files in /var/lib/libvirt/sanlock The only thing I can think of that's slightly odd about my setup is that I'm only concerned with the local machine, so that directory is not an NFS mount. Anybody have any thoughts on what's going wrong here? TIA, Dave

[libvirt] compile option: --without-gnutls
by Chris Van Heuveln 02 Jul '12

02 Jul '12

Hi libvirt-list, Full disclosure: this is the first open source project I've tried to contribute to and I'm still learning the process and tools. In any case, Mikhail Gusarov started a thread on this a while back and I've tried to take it to conclusion. I needed to remove tls for 0.8.4 so I coded up a --without-gnutls configure option using Mikhail's partial code as a template. Then I pulled down 0.9.12 and came up with a patch that I'd like to push out to the commununity. I'm not adding any "new" functionality other than the configure option. The tls calls/structs are just #ifdef'd for the most part. In a couple of places I had to flip the logic for "if (!tls_struct) else", and also had to modify a few function calls to pass void * instead of tls pointers. I built --with-gnutls, --without-gnutls, and no option specified (defaults to --with-gnutls). make check is clean except for: TEST: libvirtdconftest .....!!!!!!...!!!!!!!!!!!!!!!!!!!!!!!!! 39 FAIL ...which consists mostly of this sasl failure: 39) Test corruption ... libvir: Config File error : unsupported configuration: remoteReadConfigFile: /home/ubu/git/libvirt/tests/../daemon/libvirtd.conf: auth_tcp: unsupported auth sasl FAILED ...so I'm trying to track that down, and also need to run syntax-check and valgrind tests. Once I get the tests passing what's my next step? Are you okay with this approach? Do you want a preview of my diffs? Do I need to write additional tests for this new option or update any documentation? Thanks, Chris Van Heuveln
