[Kernel-packages] [Bug 1724165] Re: receive_freeobjects() skips freeing some objects
[Expired for zfs-linux (Ubuntu) because there has been no activity for 60 days.] ** Changed in: zfs-linux (Ubuntu) Status: Incomplete => Expired -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1724165 Title: receive_freeobjects() skips freeing some objects Status in zfs-linux package in Ubuntu: Expired Bug description: When receiving a FREEOBJECTS record, receive_freeobjects() incorrectly skips a freed object in some cases. Specifically, this happens when the first object in the range to be freed doesn't exist, but the second object does. This leaves an object allocated on disk on the receiving side which is unallocated on the sending side, which may cause receiving subsequent incremental streams to fail. The bug was caused by an incorrect increment of the object index variable when current object being freed doesn't exist. The increment is incorrect because incrementing the object index is handled by a call to dmu_object_next() in the increment portion of the for loop statement. Affects ZFS send.
