272293556a do not abort() when memory is insufficient. this fixes issue #244 2015-11-10 11:44:29 +08:00

726f45b33d Attempting to set some bits in the Unicorn EFLAGS doesn't work. 
When attempting to set all flags except trap flag, the EFLAGS value
should be 0x00244ED7, I've tested this on Windows and here
https://ideone.com/WQAvk1 which is presumably Linux.

Unicorn however has the value 0x00000ED7, bits 11-21 are not set. Bit 21
is the ID bit indicating whether or not CPUID is available.

7f3c567ae5 X86 zero-byte opcode causes Unicorn to crash. 
The opcode 0x00 translates as `add byte ptr ds:[eax],al`, which leads to
a segfault in Unicorn.

Using a debugger, I believe the crash is located in
`qemu/translate-all.c` in function `page_flush_tb_1`, more specifically
this code `pd[i].first_tb = NULL;`

696c58f9f0 Add test case for segfault-on-emu_stop() bug. 
The following code segfaults:
unicorn.Uc(unicorn.UC_ARCH_X86, unicorn.UC_MODE_64).emu_stop()

Tested under Linux and OS X.

9e64cba6ec Rename some hook related enums: 
- UC_ERR_READ_INVALID -> UC_ERR_READ_UNMAPPED
 - UC_ERR_WRITE_INVALID -> UC_ERR_WRITE_UNMAPPED
 - UC_ERR_FETCH_INVALID -> UC_ERR_FETCH_UNMAPPED
 - UC_MEM_READ_INVALID -> UC_MEM_READ_UNMAPPED
 - UC_MEM_WRITE_INVALID -> UC_MEM_WRITE_UNMAPPED
 - UC_MEM_FETCH_INVALID -> UC_MEM_FETCH_UNMAPPED
 - UC_HOOK_MEM_READ_INVALID -> UC_HOOK_MEM_READ_UNMAPPED
 - UC_HOOK_MEM_WRITE_INVALID -> UC_HOOK_MEM_WRITE_UNMAPPED
 - UC_HOOK_MEM_FETCH_INVALID -> UC_HOOK_MEM_FETCH_UNMAPPED
 - UC_HOOK_MEM_INVALID -> UC_HOOK_MEM_UNMAPPED

This also renames some newly added macros to use _INVALID postfix:

 - UC_HOOK_MEM_READ_ERR -> UC_HOOK_MEM_READ_INVALID
 - UC_HOOK_MEM_WRITE_ERR -> UC_HOOK_MEM_WRITE_INVALID
 - UC_HOOK_MEM_FETCH_ERR -> UC_HOOK_MEM_FETCH_INVALID
 - UC_HOOK_MEM_ERR -> UC_HOOK_MEM_INVALID

Fixed all the bindings Java, Go & Python.

90eb8f2e72 This commit continues the PR #111 
- Allow to register handler separately for invalid memory access
- Add new memory events for hooking:
   - UC_MEM_READ_INVALID, UC_MEM_WRITE_INVALID, UC_MEM_FETCH_INVALID
   - UC_HOOK_MEM_READ_PROT, UC_HOOK_MEM_WRITE_PROT, UC_HOOK_MEM_FETCH_PROT
- Rename UC_ERR_EXEC_PROT to UC_ERR_FETCH_PROT
- Change API uc_hook_add() so event type @type can be combined from hooking types
