Subject: [PATCH] libblkid: Fix crash while parsing config with libeconf
|
|
|
|
As the whole econf_file structure is freed by econf_free(file) at the end
|
|
of blkid_read_config(), econf_file structure cannot be defined as static
|
|
and initialized only once. The econf_free() is not robust enough and keeps
|
|
a pointer to the garbage after the first call of blkid_read_config(). And
|
|
if /etc/blkid.conf does not exist, it is called second time.
