CLFS is using two other Tar patches that apply for 1.21.
The first one, tar-1.21-manpage-1.patch, just makes a Tar manpage, and I
don't think LFS will use it anyday.
The second one, tar-1.21-revert_pipe_drain-1.patch, is a patch that is
considered to be in LFS. Why? As a example with unpatched Tar 1.21,
download this example tarball: (of Glibmm, BTW)
ftp://ftp.gnome.org/pub/gnome/sources/glibmm/2.18/glibmm-2.18.1.tar.bz2
And try to unpack it by running this command:
bzip2 -dc glibmm-2.18.1.tar.bz2 | tar xof -
Tar runs with no error, however, run strace and you will get this output:
{{{
write(1, "glibmm-2.18.1/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096)
= -1
EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
+++ killed by SIGPIPE +++
}}}
Look at this output closly and you will see that bzip2 acualy died because
of a broken pipe. Now you see why this patch is a good idea for LFS? It is
attached with this ticket.
