support/check-rpath: recognise PIE

2017-10-17T08:30:34+00:00

We sanity-check the host executables that they have a correct RPATH pointing to the host libraries. This is currently done by looking for all files in $(HOST_DIR) that match the 'ELF executable' pattern (a bit more complex, but that's idea). However, when an executable is built with -fPIE of -fpie, it no longer appears to be an 'ELF executable', but it rather looks like an 'ELF sheard object' (like if it were an library. So, we miss those files. It turns out that the problem is a real one, because quite a few mainline distros, expecially those based on Debian for example, have already switched to generating PIE code by default, and thus we miss on a whole class of systems.. We fix that by simply looking if we can find an ELF interpreter in each file. If we there is one, this is an ELF executable; if not, it may be anything else: we don't care (not even about ELF libraries). Signed-off-by: "Yann E.

support/scripts/check-bin-arch: fix symbolic link check

2017-10-16T21:00:08+00:00

Commit c96b8675ea03a5d3194d439f740c725dd239ed1a ("support/scripts/check-bin-arch: ignore symbolic links") was bogus, because it tested ${f}, which is the relative path of the file inside ${TARGET_DIR}, so we end up testing if ${f} on the system is a symbolic link. This commit fixes that by testing ${TARGET_DIR}/${f}. Signed-off-by: Thomas Petazzoni (cherry picked from commit cb0f3fa13f315a1aa0469d3479673860dcba8eb9) Signed-off-by: Peter Korsgaard

support/scripts/check-bin-arch: ignore symbolic links

2017-10-16T20:59:34+00:00

Since commit da32b49f0091ee9dfb613e0f00973bf6893bfa84 ("instrumentation: extend packages-file-list.txt with symlinks and directories"), the packages-file-list.txt also contains symbolic links. Therefore, check-bin-arch is now also checking symbolic links. However, symbolic links in $(TARGET_DIR) can have absolute path as targets, such as: $ ls -l output/target/sbin/ifdown lrwxrwxrwx 1 thomas thomas 10 Sep 3 15:55 output/target/sbin/ifdown -> /sbin/ifup Therefore, we are now potentially checking a host binary, which obviously makes check-bin-arch fail. This commit changes check-bin-arch to ignore symbolic links. Indeed, we have two cases: - The symbolic link really points to something that will in the rootfs (such as /sbin/ifup above). In this case, /sbin/ifup will be checked separately by check-bin-arch. - The symbolic link doesn't point to something that will be in the rootfs, and that is not a problem from the perspective of check-bin-arch, which checks the architecture of target binaries.

support/scripts: add fix-rpath script to sanitize the rpath

2017-07-20T20:47:04+00:00

This commit introduces the script "fix-rpath" able to scan a tree, detect ELF files, check their RPATH and fix it in a proper way. The RPATH fixup is done by the patchelf utility using the option "--make-rpath-relative ".

pkg-stats: allow to sort by column

2017-07-06T19:38:43+00:00

With 2000+ packages it's not trivial to identify i.e.: - all packages that don't have a hash file; - all packages that have patches; - all packages that have code style warnings; User experience can be improved by dynamically sorting the resulting table. There is an open-source solution that does that in the client-side and requires minimal changes to our script: sorttable.js. The script is MIT licensed as stated in its website. Also add a hint to the user that the table can be sorted. Signed-off-by: Ricardo Martincoski Cc: Arnout Vandecappelle Signed-off-by: Thomas Petazzoni

check-host-rpath: no longer allow $(HOST_DIR)/usr

2017-07-05T14:54:12+00:00

Now all packages have been updated to install things in $(HOST_DIR)/lib instead of $(HOST_DIR)/usr/lib, there should no longer be any reason to have $(HOST_DIR)/usr/lib in the RPATH, so we don't allow it any more.
