Subject: rpc: avoid uninitialized memory use
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=3157d78f52e27f704058f1f9b19276ea1d47b3cb;p=libvirt.git

rpc: avoid uninitialized memory use

Spotted by Coverity.  Gnutls documents that buffer must be NULL
if gnutls_x509_crt_get_key_purpose_oid is to be used to determine
the correct size needed for allocating a buffer.

* src/rpc/virnettlscontext.c
(virNetTLSContextCheckCertKeyPurpose): Initialize buffer.
