Getting a new target working with LAVA
Kigorky opened this issue · 2 comments
Hi,
I have been trying to understand how to get a new target working with LAVA. I tried to get a more complex project working with LAVA but it does not work so i decided to understand how to LAVA by using a simple 'Hello World' example (written in c and it can be compiled on Linux).
Hence following the doc i have a configure / make / make install
project. I created the Makefile in according to /target_injections/file/file-5.22/src/Makefile
.
First i ran the scripts/docker-shell.sh
and launched path-to-lava/tools/btrace/sw-btrace make
to build btrace.log and so forth according to the doc until the last command (Section 2.5.5 on the doc). Everything seems to be ok.
After that i added #define __attribute__(x) #define __extension__(x)
to the preprocessing script.
Next i compressed the folder of the project and put it into the /target_bins
directory. I created a .json file but i am not sure about it because i can not fully understand some fields within the file.
Finally outside the LAVA docker i ran ./scripts/lava.sh -ak test
and i got the following in the logs/inject-1.log file:
/usr/bin/python /home/ubuntu/lava/scripts/inject.py -t
ptr_add,rel_write,malloc_off_by_one -m 50 -e 0 /home/ubuntu/lava/host.json test
allowed bug types: [0, 2, 4]
Getting locked bugs directory...
Using dir /home/ubuntu/lava/target_injections/test/bugs/0
Picking bugs to inject.
Selecting 50 bugs for injection of 0 available
Traceback (most recent call last):
File "/home/ubuntu/lava/scripts/inject.py", line 163, in <module>

Can you help me please ?
This is saying that it didn't find any opportunities to inject a bug. My guess is that something went wrong with the PANDA taint analysis – could you try looking through the other log files to check if PANDA is running correctly, reporting taint analysis results, etc.?

I thought so, which log file should i look through ? the add_queries.log, make.log or dbwipe.log ?
