Sanitization is controlled by a SanitizationInformation struct to be read from the client's memory. The address of this struct is either passed in a ClientInformation when the client requests a crash dump, or as a flag to the handler --sanitization_information. Bug: crashpad:30 Change-Id: I2744f8fb85b4fea7362b2b88faa4bef1da74e36b Reviewed-on: https://chromium-review.googlesource.com/1083143 Commit-Queue: Joshua Peraza <jperaza@chromium.org> Reviewed-by: Scott Graham <scottmg@chromium.org>
