We only break out of the while loop if *content is an empty string. However the buffer has been allocated to BUFSIZ + 1 (8193 in my case), but it gets overwritten in the next for iteration. Move VIR_FREE right before we overwrite it to avoid the leak. ==5777== 16,386 bytes in 2 blocks are definitely lost in loss record 1,022 of 1,027 ==5777== by 0x5296E28: virReallocN (viralloc.c:184) ==5777== by 0x52B0C66: virFileReadLimFD (virfile.c:1137) ==5777== by 0x52B0E1A: virFileReadAll (virfile.c:1199) ==5777== by 0x529B092: virCgroupGetValueStr (vircgroup.c:534) ==5777== by 0x529AF64: virCgroupMoveTask (vircgroup.c:1079) Introduced by 83e4c77. https://bugzilla.redhat.com/show_bug.cgi?id=978352
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
