** Description changed: 2.22 added stricter mediation of sched_setscheduler which requires use of 'process-control' with certain invocations of sched_setsceduler. Testing and code searches for sched_setscheduler showed that this was - not an issue for most applications, but after 2.22 was released it was - found that qtbase-opensource-src uses sched_setscheduler indirectly as - part of QThread::Priority, and QThread::Priority is used extensively - under the hood by the libraries to support (at least) QML applications. + not an issue for most applications and existing snaps, but after 2.22 + was released it was found that qtbase-opensource-src uses + sched_setscheduler indirectly as part of QThread::Priority, and + QThread::Priority is used extensively under the hood by the libraries to + support (at least) QML applications. The fix is simple, adjust interfaces/seccomp/template.go from this: - sched_setscheduler 0 - - + sched_setscheduler 0 - - back to: - sched_setscheduler + sched_setscheduler
