* Remove obsolete seccomp_unwinder for legacy (pre-BPF) sandboxprimiano@chromium.org2015-08-186-224/+0
| | | | | | | | | | | | | | | | | | | | | The PopSeccompStackFrame was introduced to deal with stack frames originated in the legacy seccomp sandbox. The only user of that sandbox was Google Chrome, but the legacy sandbox has been deprecated in 2013 (crrev.com/1290643003) in favor of the new bpf sandbox. Removing this dead code as it has some small bound checking bug which causes occasional crashes in WebView (which are totally unrelated to the sandbox). Note: this will require a corresponding change in the chromium GYP/GN build files to roll.

* [microdump] Move microdump writes to the crash ring-buffer logprimiano@chromium.org2015-08-174-3/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the microdump_writer dumped the log in logcat using the default system log. This is simple to achieve but has some drawbacks: 1. Creates spam in the system log, pushing back other eventual useful messages. 2. There is a high chance that the microdump gets lost if some log spam storm happens immediately after a crash and before the log is collected by the feedback client. 3. Since Android L, the logger is smartly throttling messages (to reduce logcat spam). Throttling brekpad logs defeats the all point of microdumps. This change is conceptually very simple. Replace the use of __android_log_write() with __android_log_buf_write(), which takes an extra bufID argument. The main drawback is that the __android_log_buf_write is not exported in the NDK and needs to be dynamically looked up via dlsym. This choice has been discussed and advocated by Android owners. See the internal bug b/21753476.

* Add support for Linux memory mapping stream and remove ELF header usageLiu.andrew.x@gmail.com2015-07-2812-214/+885
| | | | | | | | | | | | | | | | | | | | | | | | | | | when checking exploitability rating. Linux minidumps do not support MD_MEMORY_INFO_LIST_STREAM, meaning the processor cannot retrieve its memory mappings. However, it has its own stream, MD_LINUX_MAPS, which contains memory mappings specific to Linux (it contains the contents of /proc/self/maps). This CL allows the minidump to gather information from the memory mappings for Linux minidumps. In addition, exploitability rating for Linux dumps now use memory mappings instead of checking the ELF headers of binaries. The basis for the change is that checking the ELF headers requires the minidumps to store the memory from the ELF headers, while the memory mapping data is already present, meaning the size of a minidump will be unchanged. As a result, of removing ELF header analysis, two unit tests have been removed. Arguably, the cases that those unit tests check do not merit a high exploitability rating and do not warrant a solid conclusion that was given earlier.

| | | | | | | | | | | | | When LLVM sees an attempt to dereference a NULL pointer, it will generate invalid opcodes (undefined behavior) which leads to SIGILL which breaks this unittest. Upstream's recommendation in this case is to add volatile markings to get the actual dereference to happen.

| | | | | | | | | | | | | | 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.

(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.

* 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.

* Update breakpad for Android packed relocations.rmcilroy@chromium.org2015-06-195-2/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | Shared libraries containing Android packed relocations have a load bias that differs from the start address in /proc/$$/maps. Current breakpad assumes that the load bias and mapping start address are the same. Fixed by changing the client to detect the presence of Android packed relocations in the address space of a loaded library, and adjusting the stored mapping start address of any that are packed so that it contains the linker's load bias. For this to work properly, it is important that the non-packed library is symbolized for breakpad. Either packed or non-packed libraries may be run on the device; the client detects which has been loaded by the linker.

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.

* Microdump processor: be more tolerant for different logcat formatsprimiano@chromium.org2015-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 ... In the latter case, the "/google-breakpad(" filter is too aggressive. This change is relaxing it, so it is compatible also with non-default logcat arguments.

* Workaround Android sigaction bugmark@chromium.org2015-04-101-3/+21
| | | | | | | | | | | | | | | | | On Android L+, signal and sigaction symbols are provided by libsigchain that override the system's versions. There is a bug in these functions where they essentially ignore requests to install SIG_DFL.

| | | | | | | | | | | | | | | | This is a reland of the previous CL (r1433). r1433 did not achieve what intended and failed the x86_64 build of Chrome with NDK r10c. The workaround logic in this CL is identical to r1433, but the #define magic is applied in a more appropriate proper place this time. Turns out Breakpad already has an Android compatibility layer, which is common/android/include. Piggybacking the fix there.
