LIN5-17788 : BitBake not honoring file permissions

Created: Jan 14, 2014    Updated: Dec 19, 2017
Resolved Date: Feb 10, 2014
Found In Version: 5.0.1
Fix Version: 5.0.1.12
Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Build & Config

Description

Using "install -m" or "mkdir -m" it is possible to set the required permissions for a file or directory being installed on the target, however it seems that bitbake is ignoring those permissions and setting its own.

Steps to Reproduce

$ configure --enable-board=qemux86-64 \
      --enable-rootfs=glibc_cgl --enable-kernel=cgl \
      --enable-jobs=4 --enable-parallel-pkgbuilds=4 \
      --enable-rm-work=yes --enable-rm-oldimgs=yes \
      --enable-reconfig --with-sstate-dir=<path_to_sstate> \
      --with-rcpl-version=0010

Edit layers/local/recipes-sample/hello/hello_1.0.bb as follows:

 }

Then build:

$ make -C build hello.addpkg
$ make -C build hello

Examine the results of the "ls" command in the build/hello-1.0-r2/temp/log.do_install file and you will see that the permissions for the "my_test_dir" directory are set to 0700:

drwxr-xr-x 4 root root 4096 Jan 14 13:08 .
drwxr-xr-x 6 1000 1000 4096 Jan 14 13:08 ..
drwx------ 2 root root 4096 Jan 14 13:08 my_test_dir
drwxr-xr-x 3 root root 4096 Jan 14 13:08 usr

however, 0500 had been specified in the recipe.

Examining the RPM file also indicates the wrong permissions:

$ ./host-cross/usr/bin/rpm -qvlp export/RPMS/x86_64/hello-1.0-r2.x86_64.rpm 
drwx------    2 root    root                0 Jan 14 13:08 /my_test_dir
drwxr-xr-x    2 root    root                0 Jan 14 13:08 /usr
drwxr-xr-x    2 root    root                0 Jan 14 13:08 /usr/bin
-rwxr-xr-x    1 root    root             4128 Jan 14 13:08 /usr/bin/hello

and if a "make fs" is done then again the directory will be incorrect. This also happens for files, not just directories.
