Why is the payload size `kmalloc_size-0x18` in `do_defragment`?
I was checking out how you do your defragmentation and stumbled over the do_defragment
method in user_key_payload_tmpl.h
. I noticed that the plen
parameter of add_key
is set to kmalloc_size-0x18
(equalling the payload length). I have trouble understanding this - when I look at the source of the add_key
system call, it directly passes plen
to kvmalloc
. So why do you substract 0x18, instead of directly using the size of the target cache for the allocation?
Thank you in advance for your answer!
Missing scripts
While I was trying to get this running I noticed this in Sa/staticanalyzer/objectparser/candiobjparser.py
build_util = environ["FENGSHUI_PATH"] + "/src/Sa/utils/build_candi_obj.sh"
dedup_util = environ["FENGSHUI_PATH"] + "/src/Sa/utils/candi_dedup.sh"
Where can I find these scripts?
Thank you for your help!
About the implementation of panic_xxx function
Hi, yueqi,
Thanks a lot for opening source your framework code and I learn lots from them ๐
I am really insteresting about the instrumentation of panic_xxx functions.
However, I find only the declaration in your gcc_plugin_xx.c.
I wonder if I miss something in the source code and can you help me to find out it?
Thanks agagin.
