We are encountering a build problem after migrating to Poky 2.3 and Pseudo 1.8.1, and need help to resolve this. It is hampering our development efforts, forcing us to rebuild images frequently.
Background: Our build applies SELinux file contexts, during build time since our rootfs is read-only In Poky 2.0, using Pseudo 1.6.2 this works perfectly 100% of the time Problem: Since the upgrade to 2.3 there is a 33%+ chance that the SELinux context labels will be corrupt at the end of the build. The chance is random. Cleaning and Rebuilding a bad image target results in success/failure of equal likelihood. We can go days without an error, or like this weekend all 12 builds failed! Failure mode: We have learned to identify the failure and mark builds bad based on the contents of the Pseudo SQLite database generated by the image build. A good build will have unique Inode to xattr references in the "xattrs" table. We prove pass/fail by doing a query of All entries and unique entries and verify the counts match. Example of a good result, sorted by "ino": Id dev ino name value "1" "64773" "251402120" "security.selinux" system_u:object_r:root_t "10012" "64773" "251402121" "security.selinux" system_u:object_r:var_t "7293" "64773" "251402124" "security.selinux" system_u:object_r:lib_t "19" "64773" "251402133" "security.selinux" system_u:object_r:var_run_t On a bad build, there will be numerous duplicates in this table. Why this causes the failure I do not know, but this is just what we found is indicative to failure without flashing the image on something. Example of a bad result, again sorted by "ino": Id dev ino name value "10067" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "31918" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "59307" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "61317" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "61737" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "61793" "45" "2293256211" "security.selinux" system_u:object_r:usr_t "11849" "45" "2293250079" "security.selinux" system_u:object_r:var_spool_t "66928" "45" "2293250079" "security.selinux" system_u:object_r:var_spool_t "66948" "45" "2293250079" "security.selinux" system_u:object_r:var_spool_t Any help would be greatly appreciated.
