[PATCH v3 0/3] virtiofsd: fix some accessing NULL pointer problem

Posted by Haotian Li 3 years, 5 months ago

Hi,
  We find some potential NULL pointer bugs on tools/virtiofsd.
Three patches are made to fix them

Haotian Li (3):
  tools/virtiofsd/buffer.c: check whether buf is NULL in
    fuse_bufvec_advance func
  virtiofsd: check whether lo_map_reserve returns NULL in main func
  virtiofsd: check whether strdup lo.source return NULL in main func.
