Hello tor-dev,Here goes the status report for the past 2 weeks:
- still working at [1] in public branch [2]
- rewrote how the filters work, such that a filter currently is an array of function pointers, each function being responsible of setting up the parameter filter for a syscall; also added support such that in the future it is a struct containing the array of function pointers and a linked list of parameters associated with the filter;
- I have updated the filters which proved to be a bit more challenging than expected mainly due to the multiple worker thread processes created with clone, which are harder to follow with strace;
- as of today, the latest version I have pushed has a more restrictive parameter filter which works for both a normal and ORPort launches.
TODO:
- fix open syscall problem for file names due to external library opens
- investigate socketcall syscalls' parameters failure..
- finish support for multiple filters (beginning of stage 3)
- fine-tune filters a bit (end of stage 2)
