* libafl_qemu: fix systemmode with slirp dependency libslirp will be dropped from future QEMU releases (see https://wiki.qemu.org/ChangeLog/7.0). This change adds the "slirp" feature, which links with the host-systems libslirp. * libafl_qemu: enable systemmode snapshots, vm_start Re-enable snapshot functions. Start the VM before qemu_main_loop. * libafl_qemu: allow synchronous snapshotting Add a flag to take snapshots synchronosly. This should be used to take or load snapshots while the emulator is not running. * libafl_qemu: fallback cpu for read-/write_mem In systemmode, current_cpu may not be set. In such cases use the first cpus memory access methods. * fuzzers: add example for libafl_qemu in systemmode * libafl_qemu: update libafl-qemu-bridge revision * libafl_qemu: add memory access by physcial address * fix liabfl_qemu example Use GuestAddr and physical memory access * ci: install libslirp-dev for libafl_qemu * fuzzers/qemu_systemmode: clean up example * libafl_qemu: remove obsolete functions emu::libafl_cpu_thread_fn emu::libafl_start_vcpu emu::start * fuzzers/qemu_systemmode: simplify example * improve build_linux.rs * Update qemu_systemmode fuzzer * upd * clippy Co-authored-by: Alwin Berger <alwin.berger@tu-dortmund.de> Co-authored-by: Andrea Fioraldi <andreafioraldi@gmail.com>
