* Fixing a flaky Linux exploitability unittest.Ivan Penkov2016-02-163-15/+81
| | | | | | | BUG=https://code.google.com/p/chromium/issues/detail?id=584174 R=mmandlis@chromium.org Review URL: https://codereview.chromium.org/1697963002 .
* Ensure Linux minidump writer flushes minidump header early.Ted Mielczarek2016-02-121-11/+18
| | | | | | | | | | | | | | | | If the Linux minidump writer crashes while writing a dump, the dump might contain some useful information, but the header will be empty because TypedMDRVA's destructor flushes the data, and the header var doesn't go out of scope until the end of the `Dump` method. This fixes that problem by putting the header in a shorter block scope. We've seen this problem in some Android dumps in the wild, like: https://crash-stats.mozilla.com/report/index/cef5b777-02d1-43c2-bf40-133ab2160209 R=thestig@chromium.org BUG=https://bugzilla.mozilla.org/show_bug.cgi?id=1247978 Review URL: https://codereview.chromium.org/1696573003 .

* Change MDCVInfoELF into something usable.Ted Mielczarek2016-02-104-45/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes MDCVInfoELF (which is currently unused, apparently a vestigal bit of code landed as part of Solaris support) into a supported CodeView format that simply contains a build id as raw bytes. Modern ELF toolchains support build ids nicely: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Developer_Guide/compiling-build-id.html It would be useful to have the original build ids of loaded modules in Linux minidumps, since tools like Fedora's darkserver allow querying by build id and the current Breakpad code truncates the build id to the size of a GUID, which loses information: https://darkserver.fedoraproject.org/ A follow-up patch will change the Linux minidump generation code to produce MDCVInfoELF in minidumps instead of MDCVInfoPDB70. This patch should be landed first to ensure that crash processors are able to handle this format before dumps are generated containing it. The full build id is exposed as the return value of Minidump::code_identifier(), which currently just returns "id" for modules in Linux dumps. For backwards-compatibility, Minidump::debug_identifier() continues to treat the build id as a GUID, so debug identifiers for existing modules will not change.

| | | | | | | | | | | | | | | Newer gcc versions default to -Werror=narrowing when using newer C++ standards (which we do). This causes issues when we try to stuff a value like 0xea into a char -- the value is out of range for signed char bytes. That's when gcc throws an error: .../bytereader_unittest.cc: In member function 'virtual void Reader_DW_EH_PE_absptr4_Test::TestBody()': .../bytereader_unittest.cc:400:55: error: narrowing conversion of '234' from 'int' to 'char' inside { } [-Wnarrowing] BUG=chromium:579384 TEST=`make check` passes R=mark@chromium.org Review URL: https://codereview.chromium.org/1605153004 .

* test: stop building tons of copies of gtest/gmock objectsMike Frysinger2016-01-252-1667/+378
| | | | | | | | | | | | | | | | | | | | The current makefile ends up building ~17 copies of the gtest/gmock objects -- every test that refers to the cc files directly will have its own copy. This is because the build doesn't know if CFLAGS and such have changed between each target (and in some cases, they are). Create a new libtesting.a target to hold a single copy of these files and update all of the unittests to link that in. This speeds up the build a bit especially when you aren't using ccache. This does mean we can no longer build gtest/gmock with unique flags, but we haven't wanted that so far, so clearly no one wants that.

* Don't include libdisasm.a in libbreakpad.aMike Frysinger2015-11-112-4/+1
| | | | | | | | | | | | | | libbreakpad.a pointlessly contains libdisasm.a This looks like a left-over from when libtool was used Since this has no useful effect (as the linker doesn't recursively search archive members which aren't objects), anything which requires the objects in libdisasm.a must already be linking with it, so simply remove it.
