    libdiskfs: add permission check to file_chflags
    
    Only root is allowed to change the high 16 bits.  The TODO entry says
    otherwise, but that must be a mistake.  For reference, see the glibc
    sources, sysdeps/mach/hurd/bits/stat.h.
    
    * libdiskfs/file-chflags.c (diskfs_S_file_chflags): Add permission
    check.
    * TODO (libdiskfs): Remove entry.

    libports: avoid realloc(3) corner case
    
    If the size argument is 0, realloc may either return NULL, or return a
    pointer that is only valid for use with free(3).  In either case, the
    memory is freed.  So if realloc would return NULL (it does not on
    GNU), the current code would double free p.
    
    Found using the Clang Static Analyzer.
    
    * libports/bucket-iterate.c (_ports_bucket_class_iterate): Avoid
    calling realloc if no ports were matched.

    trans/fakeroot: fix error handling
    
    Found using the Clang Static Analyzer.
    
    * trans/fakeroot.c (new_node): Do not leak a pointer to freed memory.
    Store NULL at *np instead.  This fixes a node use-after-free in
    netfs_S_dir_lookup.

    libshouldbeinlibc: fix dead initialization in fmt_named_interval

    * libshouldbeinlibc/timefmt.c (fmt_named_interval): Fix dead
    initialization.
