bench: Fix target to not include null termination.

Request of the target must not be null terminated. Remove null termination from
the requests constructed by peers.

bench: Flush stdout when printing progress results

bench: Fix issuing of read/write requests

Due to no initialization of struct bench, some "ifs" in the code would
show different behavior depending on the junk values they would check.
Now however, there is proper initialization of struct bench.

Add progress report for bench

Progress report is turned on by default. It reports every 5% the current
request status.
Also, we now make sure to terminate only if all peer requests are free.

bench: Change prefixes of static functions

In this repo, a static helpder function is prefixed with "__". However,
some static helper functions in bench-utils.c where prefixed with a
single underscore ("_"), so we updated their names to be consistent with...

Style changes

Add option for read/write ops to hit unique objs

Read/write ops can now use the -to option, instead of the -ts option, to
make each read/write request touch a different object.

Improve LFSR implementation

Also, prepare the code for the addition of verification support

Add skeleton for verification in write path

Refactor struct bench and appropriate code paths

Changes:

1. Move flag values (such as pattern, insanity, verify) in a specific
bit-field.
2. Create a struct req_status where the status of requests will be
stored.
3. Tidy up code.

Rationale:

1. For parameters that can have only a few different values, it's an...

Add partial support for verification

Adds an option to choose between verification modes:

1. meta: On this mode, we write our signature both at the start and the
end of the chunk size. It should be very fast and moderately safe,
due to the fact that corruptions happen it the chunk's edges....

Minor fixes

Add support for seed values given by the user

A new option has been added (--seed) which allows the user to pre-define
the seed that he/she wants. This has the following effects:

  • The target names are prefixed with the first 9 digits of the seed.
  • LFSR produces a predictable sequence of "random" numbers

Tweak performance of bench

Implement most semi-finished functionalities

Summary of new functionalities:

  • Add support for 4 different xseg operations (read, write, info,
    delete).
  • Add support for random I/O patterns with a fast Galois LFSR.
  • Add insanity levels in timers, which allow the user to exclude obscure...

Increment completed requests of insane timers

Even if a timer is not used for a benchmark, we need to increment its
completed requests since these are needed to calculate how many requests
are left etc.

Fix flag handling of struct bench

Design the program's skeleton for new features

Bench peer must be able to test all xseg operations in a synchronous or
asynchronous way. Also, it must have a validation mode to sanity-check
if xseg requests are issued properly. Most of the above are present in...
