The MIT license was missing from the license list for util-linux. Add
a patch, submitted to upstream which adds the missing license mentions.

Add a version of flock that uses the fnctl based lockf locking instead of
flock based locks. This allows us to take the same lock that opkg would
use from a shell script. The two different locking mechanisms operate
independently of each other.
Inserting this C file into the util-linux build seems like the easiest/best
place to insert the code. At this point it hasn't been discussed with upstream.

* [PATCH 3/3] run-postinsts: Add workaround for locking deadlock issue
2024-03-29 16:17 [PATCH 1/3] util-linux: Add missing MIT license Richard Purdie

From: Richard Purdie @ 2024-03-29 16:17 UTC (permalink / raw
To: openembedded-core
When run-postinsts is installed, a service is added for system which can run
while the package is still being installed. This calls "opkg configure" and if
package management is still running, it can deadlock and error.
To work around this, call fcntl-lock on the opkg lock file and if the lock
was held, it would wait to obtain it. This wait gives the package management
time to finish the install before the configure can then take the lock and run.
Note the dependency in SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS otherwise we'd see
sstate selftest failures.
Also ensure that if the configure fails, the scripts returns an error. This
applies to opkg and dpkg.
