The initialization value for ymin, which tracks the lower bound of
plotted rectangles (and is finally used for the preselected zoom
area), was chosen too small for Linux-kernel data structure addresses.

Upstream SVN r12754: "Fixed PCI IDE controller DMA start (found with a
recent Linux version: "mode sense" command executed in DMA mode).
Updated output of "mode sense" page 0x2a (still reporting CD-ROM
drive)."
(data_ready part not backported due to missing dependency)

Upstream SVN r12563: "Bugfix: use memmove() if source and destination
range can overlap (found with valgrind)."
(Manually backported, the code structure has significantly changed
before this fix.)

Upstream SVN r10244: "Fixed possible buffer overflow causing segfault
or memory corruption. The buffers are not large enough for the maximum
sector count in LBA48 mode. Now resetting buffer pointers after
processing a PRD (and move remaining data if necessary). This should
fix the SF bug items #3190970 and #3077616."
This happened to us when booting Debian 8 with a Linux 3.16 kernel
from "flat" or "volatile" disk images, in the end corrupting the VGA
card's ("theVga") internal state and segfaulting.

FindLLVM.cmake now starts searching for specific "llvm-config-x.y"
versions instead of using the system-wide default "llvm-config" first.
This avoids breaking builds on Debian 8, where LLVM 3.5 is the (yet
unsupported) default, but 3.4 is still installable.

Before this change, the GenericExperiment only recorded port 0xe9 output
*after* the fault was injected. When a fault was injected during the
workload's output loop, the output data before that point in time was
missing, and the experiment outcome was wrongly classified as SDC.
This change moves the logging activation to before the fast-forwarding
step (DatabaseExperiment::cb_before_fast_forward). It also makes sure the
DatabaseExperiment only clears its own listeners instead of also touching
the SerialOutputLogger's one.

Limit the serial-output logger buffer to prevent overly large memory
consumption in case the target system ends up, e.g., in an endless loop.
The buffer is limited to (golden-run output size)+1 to be able to detect
the case when the target system makes a correct output but faultily adds
extra characters afterwards.

This change prevents an integer overflow in the memory-access listener
for WRITE_OUTERSPACE. Instead of matching all addresses above
maxima_data, l_mem_outerspace never matched in the
generic-experiment's "--catch-write-outerspace" mode.

Before this change, ymin was rounded down to the nearest Y value
divisible by 1000, showing an empty, white area in the lower part of
the plot. With this change, the initial Y-axis zoom level is
maximized to exactly show all non-white areas.
Change-Id: I1aea52a3afc331e7f11fe76ff2c5de3c71c61c71
In the current configuration, OK_MARKER would be plotted in white
color and be indistinguishable from the background. Not plotting
these areas at all reduces output-file size. As a side effect, the
initial Y-axis zoom level (ymin, ymax) can change.

By default, the data-aggregator scripts create machine-readable,
tab-separated output. The optional "-t" switch (passed to the
internally used `mysql' command-line client) creates human-readable
table output instead.

This change additionally allows to create a resulttype/occurrences summary
over all benchmarks in the database, instead of specifying a single one.

Instead of using the address difference between two neighboring symbols as
an indication for the symbol's size, import the size as reported by
`nm -S'.
Additionally, this change fixes an off-by-one, which had the effect that
the last symbol in the list was not imported at all.

This change introduces a loose collection of scripts for
analysis/aggregation of FAIL*'s collected data.
It's going to be developed into a proper tool in the future.

This change adds the capability to import an ELF's symbols
into the database. The functionality is implemented via a
shell script and will be merged into "import-trace", when
it's being cleaned up sometime in the near future, but for
now this suffices.

This change adds detection of SDCs to GenericTracing and
GenericExperiment via Bochs's I/O port E9.
Change-Id: Ie036aa97468b45cad94b6c8f73d1ef2d227547b2
This change introduces the ability to inject burst faults to
the DatabaseCampaign/-Experiment and thus to all derived
campaigns/experiments.

Up until now only generic-tracing had the feature to directly
pass an ELF file to the experiment. generic-experiment lacked
that functionality and resorted to using the $FAIL_ELF_PATH
environment variable.
This change introduces the "--elf-file" command line argument
to generic-experiment.
Change-Id: Ie74de9e1781275ab247786856e13e412bac39224
This change adds the faultspace-plotting scripts into FAIL*'s
tools/analysis/ folder and makes it CMake-configurable.

- Debian 8 does not provide libsvga1-dev anymore, so Bochs cannot be
built --with-svga (which is included in --with-all-libs).
- The latest AspectC++ nightlies should work without any
-D__NO_MATH_INLINES -D__STRICT_ANSI__ tricks.

ERIKA Enterprise is a OSEK conforming embedded RTOS. The supplied tracer
and experiment are similar to the cored-{tracing,tester} experiment, but
checks the integrity of the RTOS application in a different
manner. Stacks and stackpointers are located differently in ERIKA. This
experiment was used in RTAS'15 Hoffmann et al.

With the instantiate-indirect.ah method, we can choose between different
experiment flows at runtime. By this, we can combine tracing and actual
injection into one fail-client binary. A -Wf,--mode={tester,tracer}
switch does hand the control to different experiment flows.

For redoing the bench-coptermock-isorc experiment, we have to change the
timeout settings. We now use a soft timeout setting. A soft timeout is
resetted after each checkpoint event. If a hard timeout (2 seconds) is
reached although the soft timeout was resetted, we also abort the injection.
