With BSIZE=$(stat -c "%o" $LOCAL_FILE) ## 4096 `./unit-utils-io $LOCAL_FILE read_buffer $((BSIZE-1))` fails with ext4 (on read()) and tmpfs (on open(O_DIRECT)), but succeeds with btrfs (and possibly other file systems). The test-suite doesn't pass if that test succeeds.
We'll add some less pedantic mode for tests related to misaligned direct I/O on filesystems.
Ah, btrfs. Until now it was nfs nuances that breaks everything :-) (Direct-io should not be able to read buffer not aligned to block/page boundary, but btrfs has apparently disagrees.)
Not only misaligned read. It passes even for misaligned direct write! I'm getting old for this... :)
Anyway, thank you for the report! O. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx https://www.saout.de/mailman/listinfo/dm-crypt
