Package: evms Version: 2.5.2-1 Severity: critical Justification: causes serious data loss
This is mainly a placeholder bug for my upcoming EVMS upload to stable; it has already been addressed in unstable (and will eventually progress to testing). (A -done message informing the BTS about the fact that 2.5.3 fixes it will be sent shortly.) EVMS prior to 2.5.3 has a buffer overflow when dealing with degraded RAID-5 volumes; in short, the wrong memory gets overwritten and EVMS segfaults. This can render the entire system unbootable (since the root volume might be on RAID-5, and evms_activate crashes upon loading the md plugin), but I've also seen it eat the RAID-5 superblock. There is also a bug where the engine might segfault when doing a RAID-5 expand, but AFAIK, all this does is to segfault evms; I haven't seen it cause data loss. Also, RAID-5 expand is sort of an infrequent use case anyhow... The solution is to simply backport the RAID-5 fixes from 2.5.3 into 2.5.2. The two entries from the changelog are: - Fix stack corruption bug in MD plugin. [Marcus Meissner] - Fix memory corruption bug for RAID-5 regions running in degraded mode.
