Linux 2.5.46 made changes to the ptrace(2) API to inform a tracer when various
events occur. These are known as PTRACE_EVENTs. Start handling PTRACE_EVENTs
by:
* Handling PTRACE_EVENT_FORK and PTRACE_EVENT_EXIT
* For _FORK, stores the newly created pid in dbg->forked_pid
* Add the "dpc" command to select the most recently forked child process.
* Add the "dpc*" command to show the recently forked process' pid.
Additional minor changes to white space are included.
NOTE: This partially addresses #3549. It does handleLinux before 2.5.46.
* Fix "dbm" help string
* Save <module>+<offset> as the name when using dbm
* Fix allocation patterns for "module"
* Remove commented out code
* White space fixes
When resuming after (during) recoil from a breakpoint, the swstep
implementation would fail to advance. In short, the debugger would immediately
interrupt again because r_bp_restore was re-setting the original breakpoint
just before continue. The following changes fix this issue:
1. Modify r_bp_get_in to stop including the byte after a breakpoint. This was
causing r_bp_recoil to fail because it thought there was already a breakpoint
on the next instruction.
2. Pass the real breakpoint address (pc - dbg->bpsize) to r_bp_recoil so
that r_bp_get_in can work properly. Stop adding the b->size there to keep it
going too.
3. Add a state flag to core->dbg to track that we are in the midst of a recoil.
4. When continuing from recoil (in r_debug_continue_kill), restore all
breakpoints except the one we just hit (with the new r_bp_restore_except) to
avoid hitting it again. Once we move past this instruction, that breakpoint
will be set again.
some rework in order to handle mach message as mach_exc_server and alike does
api change in plugin debug, now the function detach receive a pointer to RDebug
trying to deallocate port when are not needed any more
- Implemented in r_debug_esil_* APIs
- Support for step-into and continue
- Expressions can be regs, numbers, math operations, ranges, comparisons..
- Honor dbg.prestep for stepping before or after analysing
- read-write-exec watchpoints using native debug backend and esil emulation
- OSX/iOS debugger error message is now nicer
- anal/rpnesil renamed to esil
- Add esi,edi in osx regprofile
- Add r_cons_is_breaked() for consistency
