package/squashfs: add upstream patch to fix symlinks
Since version 4.5, squashfs-tools provides two additional utilities: sqfstar and sqfscat. But their functionality is bundled within mksquashfs and unsquashfs respectively, so that sqfstar is a symlink to sqfstar, and sqfscat a symlink to unsquashfs. Unfortunately, due to how the symlinks were created, they had a bogus target when INSTALL_DIR was not empty, leading to things like this: ./usr/bin/sqfscat -> /home/peko/autobuild/instance-1/output-2/target/usr/bin/unsquashfs ./usr/bin/sqfstar -> /home/peko/autobuild/instance-1/output-2/target/usr/bin/mksquashfs Not only they are wrong, but they also cause reproducible build issues (this is how they were detected). This commit backports an upstream patch that fixes this problem. This is also fixing the squashfs-tools part of the reproducible build issues at: http://autobuild.buildroot.net/results/00af5dca8c30b243af1e8cde3b02e264f7603442/diffoscope-results.txt Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.

Subject: [PATCH] Avoid use of INSTALL_DIR for symlink targets
|
||||
|
||||
In case INSTALL_DIR is overridden with a staged install location, using
|
||||
INSTALL_DIR for the symlink target path prefix will yield an incorrect location
|
||||
for the final installation.
|
||||
|
||||
Because the symlink itself is already installed to INSTALL_DIR, simply removing
|
||||
the INSTALL_DIR prefix suffices as a fix.
|
||||
|
||||
Note that using $DESTDIR/$INSTALL_DIR where appropriate can avoid this type of
|
||||
issue, but that can be considered a future enhancement.
