io_u_qiter: Fix buffer overrun
In io_u_queue.h the io_u_qiter macro is loops around io_u_queue
structures. The problem comes with the end of loop initialisation:
i++, io_u = (q)->io_us[i]
For example, if io_us consists of one element and i is 0 then after the
first iteration is completed i++, io_u = (q)->io_us[i] will access
beyond the end of io_us.
Fix this by moving io_u initialisation to the expression part of the for
loop (yuck).

Fix rand_seed mismatches in verify phase
In verify phase, the rand_seed generated on replay does not match
the written rand_seed.
Multiple problems are causing this:
1. In verify phase fio does not set io_u->rand_seed to compare with
hdr->rand_seed
2. In randrw scenario, fio log is stored in red-black tree in "sorted by LBA"
order. Thus, it is imposible to replay the written order, or rather
generate the seeds again in the same order.
3. In write phase, the code currently will generate rand_seed, write data
and log rand_seed. When queuedepth > 1, it's possible the writes complete
in a different order than rand_seed was generated. Thus when replaying
the log, the generated rand_seed might not match what was written.
4. verify_backlog option will start verification before all the data has been
written and it make rand_seed replay code broken with current design.
Proposed fixes:
1. Use of existing verify_state to generate verify header.
(and assumes this was the original intention of verify_state). And also
adds code to replay rand_seed in verify phase.
2. If verifysort option is not enabled, store the write log in a list instead
of the red-black tree. Otherwise, don't attempt to verify the rand_seed
in the header.
3. In write phase, generate rand_seed, log rand_seed, write data. I.e. log
IO transactions in the order generated, not completed.
4. Don't verify rand_seed when verify_backlog is enabled.

The blktrace format is stored in the native endianness of

Add support for O_ATOMIC
O_ATOMIC makes writes atomic, meaning that they are fully stable
on media (in the event of a power cut) when acknowledged by the
device and OS.
This only truly works on Linux with the pending patches to
add O_ATOMIC.
Updated by Jens to:
- Add man page and HOWTO description of the option
- Make O_ATOMIC imply O_DIRECT, so that it actually works if you
don't set O_DIRECT manually.
- Add the option to the conversion list so it works for
client/server.
- Error handling so that if atomic=1 is set and the OS does not
support it, error out instead of just pretending it works.
