tar 1.27 subtly changed the tar format when a GNU long link entry is added
(which is done for path elements > 100 characters). The code used to set
the permission mode of the link entry to 0:
header = start_private_header ("././@LongLink", size, time (NULL));
FILL (header->header.mtime, '0');
FILL (header->header.mode, '0');
FILL (header->header.uid, '0');
FILL (header->header.gid, '0');
FILL (header->header.devmajor, 0);
FILL (header->header.devminor, 0);
This got dropped in 1.27 by commit df7b55a8f6354e3 (Fix some problems with
negative and out-of-range integers), so the settings from
start_private_header() are used directly - Which are:
TIME_TO_CHARS (t < 0 ? 0 : min (t, MAX_OCTAL_VAL (header->header.mtime)),
header->header.mtime);
MODE_TO_CHARS (S_IFREG|S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH, header->header.mode);
UID_TO_CHARS (0, header->header.uid);
GID_TO_CHARS (0, header->header.gid);
The end result is that tar >= 1.27 sets mode to 644.
The consequence of this is that we create different tar files when long path
names are encountered (which often happens when a package downloads a
specific sha1 from a git repo) depending on the host tar version used,
causing hash mismatches.
As a workaround, bump our minimum tar version to 1.27. It would be nicer to
only do this if we have packages from bzr/git/hg enabled, but that is an
exercise for later.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
