[libvirt] [PATCH 2/2] security: apparmor: load the storage driver dynamically

In commit 5e515b542d I've attempted to fix the inability to access storage from the apparmor helper program by linking with the storage driver. By linking with the .so the linker complains that it's not portable. Fix this by loading the module dynamically as we are supposed to do. --- Notes: This patch is possible even with the previous patch, but it would be slightly more complex, since it would need the logic to determine whether to load the module or just initialize it. src/Makefile.am | 2 +- src/security/virt-aa-helper.c | 10 +++++----- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/src/Makefile.am b/src/Makefile.am index 471be40d1..b8e875482 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -3124,7 +3124,7 @@ virt_aa_helper_LDADD = \ libvirt.la \ libvirt_conf.la \ libvirt_util.la \ - libvirt_driver_storage.la \ + libvirt_driver_storage_impl.la \ ../gnulib/lib/libgnu.la if WITH_DTRACE_PROBES virt_aa_helper_LDADD += libvirt_probes.lo diff --git a/src/security/virt-aa-helper.c b/src/security/virt-aa-helper.c index a751d6deb..35dcb35bc 100644 --- a/src/security/virt-aa-helper.c +++ b/src/security/virt-aa-helper.c @@ -41,6 +41,7 @@ #include "viralloc.h" #include "vircommand.h" #include "virlog.h" +#include "driver.h" #include "security_driver.h" #include "security_apparmor.h" @@ -56,7 +57,6 @@ #include "virgettext.h" #include "storage/storage_source.h" -#include "storage/storage_backend.h" #define VIR_FROM_THIS VIR_FROM_SECURITY @@ -927,10 +927,10 @@ get_files(vahControl * ctl) goto cleanup; } - if (virStorageBackendDriversRegister(false) < 0) { - vah_error(ctl, 0, _("failed to register storage driver backend")); - goto cleanup; - } + /* load the storage driver so that backing store can be accessed */ +#ifdef WITH_STORAGE + virDriverLoadModule("storage", "storageRegister"); +#endif for (i = 0; i < ctl->def->ndisks; i++) { virDomainDiskDefPtr disk = ctl->def->disks[i]; -- 2.13.2
