farmdve 036763d6ae Fix memory leaks as reported by DrMemory and Valgrind. 
ARM and probably the rest of the arches have significant memory leaks as
they have no release interface.

Additionally, DrMemory does not have 64-bit support and thus I can't
test the 64-bit version under Windows. Under Linux valgrind supports
both 32-bit and 64-bit but there are different macros and code for Linux
and Windows.

Nguyen Anh Quynh 3a36e327ab support memory redirection, so the issue #217 is fixed 2015-10-27 14:37:03 +08:00
Nguyen Anh Quynh b1d41d414b on some hook events, uc_hook_add() should not allow more than 1 handler. this add UC_ERR_HOOK_EXIST error type 2015-10-10 18:01:47 +08:00
Nguyen Anh Quynh 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.

Nguyen Anh Quynh 738b8d89f9 correct instructions for uc_cb_hookmem_t & uc_cb_eventmem_t. this fixes a part of issue #151 2015-09-24 18:50:49 +08:00
Nguyen Anh Quynh 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

Sean Heelan dfb4a9d9ad Revert "Remove uc_cb_eventmem_t as it is identical to uc_cb_hookmem_t" 
As pointed out by aquynh the return types are actually different. A
uc_cb_eventmem_t callback returns a bool, while uc_cb_hookmem_t has a
void return type.

This reverts commit cb2b97f26c.
 2015-09-23 12:51:47 +07:00
Sean Heelan 2ef59e5727 Renamed UC_HOOK_MEM_INVALID_[READ/WRITE/FETCH] to 
UC_HOOK_MEM_[READ/WRITE/FETCH]_INVALID as per aquynh's feedback.
 2015-09-23 12:48:13 +07:00
Sean Heelan cb2b97f26c Remove uc_cb_eventmem_t as it is identical to uc_cb_hookmem_t, as per 
issue #111
 2015-09-22 12:37:05 +07:00
Sean Heelan 75c5904ec1 Makes the hook types consistent, with a single indicator for each of 
read, write and fetch.

This commit only adds the enum values. The functionality still has to be
updated.

As per issue #111
