Title:
memcpy: detected field-spanning write (size 8) of single field "lr +
1"
Status in zfs-linux package in Ubuntu:
Confirmed
Status in zfs-linux source package in Oracular:
Confirmed
Bug description:
SRU Justification
[Impact]
* Having occurrences of "detected field-spanning write" on zpool
import. Logs included below SRU justification
[Fix]
* Backport 6f50f8e16b7c: "zfs_log: add flex array fields to log record
structs"
* Backport c84a37ae93b5: "lua: add flex array field to TString type"
[Test Plan]
* Compile tested
* Run through autopkgtest regression tests
[Regression potential]
* Changes already in upstream ZFS. lua changes are quite small. Otherwise
adding
a new struct is added, which could lead to allocation issues if not managed
properly.
I upgraded one of my systems to Oracular and noticed this error:
