* Add ELF header analysis when checking for instruction pointer in code.Liu.andrew.x@gmail.com2015-07-169-10/+207
| | | | | | | | | | | | | | If the minidump module containing the instruction pointer has memory containing the ELF header and program header table, when checking the exploitability rating, the processor will use the ELF header data to determine if the instruction pointer lies in an executable region of the module, rather than just checking if it lies in a module.

* Set exception whitelist check as earlier check instead of last check.Liu.andrew.x@gmail.com2015-07-071-15/+15
| | | | | | | | | | | | | | | When I first added the exception whitelist, I meant to put the check before checking the location of the instruction pointer. (I didn't notice that it was after the other check until now.) The whitelist check is to quickly rule out minidumps, and if checking the instruction pointer provided any useful information, it would be pretty indicative that the exception causing the dump is interesting.

* Checking for benign exceptions that trigger a minidump.Liu.andrew.x@gmail.com2015-06-303-3/+62
| | | | | | | | | | | | | If the exception reponsible for the crash is benign, such as a floating point exception, we can rule out the possibility that the code is exploitable. This CL checks for such exceptions and marks the dump as not exploitable if such an exception is found.

Verification is done by obtaining a memory mapping of the crash and checking if the instruction pointer lies in an executable region. If there is no memory mapping, the instruction pointer is checked to determine if it lies within a known module.

* Fix signal propagation logic for Linux/Android exception handler.primiano@chromium.org2015-06-221-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code is relying on info->si_pid to figure out whether the exception handler was triggered by a signal coming from the kernel (that will re-trigger until the cause that triggered the signal has been cleared) or from user-space e.g., kill -SIGNAL pid, which will NOT automatically re-trigger in the next signal handler in the chain. While the intentions are good (manually re-triggering user-space signals), the current implementation mistakenly looks at the si_pid field in siginfo_t, assuming that it is coming from the kernel if si_pid == 0. This is wrong. siginfo_t, in fact, is a union and si_pid is meaningful only for userspace signals. For signals originated by the kernel, instead, si_pid overlaps with si_addr (the faulting address). As a matter of facts, the current implementation is mistakenly re-triggering the signal using tgkill for most of the kernel-space signals (unless the fault address is exactly 0x0). This is not completelly correct for the case of SIGSEGV/SIGBUS. The next handler in the chain will stil see the signal, but the |siginfo| and the |context| arguments of the handler will be meaningless (retriggering a signal with tgkill doesn't preserve them). Therefore, if the next handler in the chain expects those arguments to be set, it will fail. Concretelly, this is causing problems to WebView. In some rare circumstances, the next handler in the chain is a user-space runtime which does SIGSEGV handling to implement speculative null pointer managed exceptions (see as an example http://www.mono-project.com/docs/advanced/runtime/docs/exception-handling/) The fix herein proposed consists in using the si_code (see SI_FROMUSER macros) to determine whether a signal is coming form the kernel (and therefore just re-establish the next signal handler) or from userspace (and use the tgkill logic). Repro case: This issue is visible in Chrome for Android with this simple repro case: - Add a non-null pointer dereference in the codebase: *((volatile int*)0xbeef) = 42 Without this change: the next handler (the libc trap) prints: F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x487 where 0x487 is actually the PID of the process (which is wrong). With this change: the next handler prints: F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0xbeef which is the correct answer.

| | | | | | | | | | | | | | | | | | | | | | | The current processor implementation is grepping for /google-breakpad( in the logcat lines, to filter out microdump lines, which by default look like this: W/google-breakpad( 3728): -----BEGIN BREAKPAD MICRODUMP----- Turns out that logcat format can vary, when passing optional arguments, and produce something like the following: 04-13 12:30:35.563 6531 6531 W google-breakpad: -----BEGIN ...

Conversion is unified in a single function, and additional uses of time_t in minidump files not previously displayed in UTC are now displayed. - Interpret the IMAGE_DEBUG_MISC structure correctly. - When printing MINIDUMP_SYSTEM_INFO structures, always show the "x86" side of the union, and state whether it's expected to be valid. (Existing Breakpad-produced non-Windows minidumps for x86_64 use the "x86" side of union, but Windows minidumps for x86_64 use the "other" side, so I want to print both.)

If alignment operators are found in the program string, the current value of %ebp must be valid and it is the only reliable data point that can be used for getting to the previous frame.

There is code that is trying to work around this problem (scanning of up to 3 words for a return address) which is unreliable and it doesn't work in many cases (e.g. when the alignment is on a 64-byte boundary).

* Handle block helper functions in Breakpad symbol parser. Block helper ↵ivan.penkov@gmail.com2013-09-191-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | functions are associated with a source file but not associated with any line number. For such functions, the Breakpad symbol file contains 0 for the line numbers. Hence, 0 should be threated as valid line number. For more information on block helper functions, please, take a look at http://clang.llvm.org/docs/Block-ABI-Apple.html.

| | | | | | | | | | | | | | This creates a pseudo stack-walker which does nothing except symbolize an already walked array of addresses.

* Updating MDRawMiscInfo to support verions 3 and 4 of the ↵ivan.penkov@gmail.com2013-08-021-53/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MINIDUMP_MISC_INFO_N structure. Added the necessary code for swapping and string conversion from UTF-16. Found and fixed a bug in MinidumpAssertion::Read where the max string length passed to UTF16codeunits was in bytes instead of UTF-16 chars. Tested with a minidump containing a version 3 structure to validate the string conversion routines. Interestingly enough the time_zone names does not appear to be abbreviation as the documentation was suggesting but full names, e.g. Eastern Standard Time: MDRawMiscInfo size_of_info = 232 flags1 = 0xf7 process_id = 0x54c4 process_create_time = 0x51a9323c process_user_time = 0x1 process_kernel_time = 0x0 processor_max_mhz = 3100 processor_current_mhz = 1891 processor_mhz_limit = 3100 processor_max_idle_state = 0x1 processor_current_idle_state = 0x1 The new fileds follow: process_integrity_level = 0x1000 process_execute_flags = 0x4d protected_process = 0 time_zone_id = 2 time_zone.bias = 300 time_zone.standard_name = Eastern Standard Time time_zone.daylight_name = Eastern Daylight Time Review URL: https://breakpad.appspot.com/617002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1204 4c0a9323-5329-0410-9bdc-e9ce6186880e
