Crash Dump Section Integrity via Content File Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing systems often experience crashes due to hardware or software failures, leading to corrupted or truncated crash dump files, which hinder debugging efforts as they may become unusable for determining the cause of the system crash.
Innovation Solution
A method involving the creation of a content file with section parameters and information during the generation of the crash dump file, allowing for the identification of corrupted or truncated sections by comparing these parameters with valid versions, enabling debugging administrators to assess the reliability and usability of the crash dump file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the crash dump file is generated and transmitted for analysis, then debugging capability is enabled, but the file may get corrupted during transmission or storage
Solution Approach 1:
The patent applies preliminary action by generating a content file with section parameters and information about the crash dump file sections before transmission. This content file serves as a reference guide that describes the expected structure and content of each section. When corruption occurs during transmission or storage, the debugging administrator can use the content file to identify which sections are corrupted and which are still valid, enabling partial analysis of the crash dump file.
Solution Approach 2:
The patent creates a copy of the crash dump file's structural information in the form of a content file. This content file contains section parameters, offsets, and information about each section without containing the actual crash data. This copy serves as a metadata reference that can be used to verify the integrity of the actual crash dump file sections and identify corrupted areas.
2Loss of information
If the entire crash dump file is analyzed, then complete debugging information is obtained, but corrupted sections reduce the usability of the file
Solution Approach 1:
The patent segments the crash dump file into multiple distinct sections, each with its own parameters and information recorded in the content file. This segmentation allows the debugging process to identify and work with only the valid, uncorrupted sections while ignoring corrupted ones. The content file provides the structure needed to navigate and select specific sections for analysis, enabling partial but effective debugging even when parts of the file are damaged.
Solution Approach 2:
The patent applies local quality by treating different sections of the crash dump file differently based on their integrity status. The content file enables the debugging administrator to identify which specific sections are corrupted and which are valid, allowing focused analysis on reliable sections rather than attempting to process the entire file uniformly. This selective approach maximizes the usable debugging information extracted from the crash dump.
3Difficulty of detecting and measuring
If section parameters are recorded for all sections, then corruption detection capability is improved, but the complexity of file generation increases
Solution Approach 1:
The patent introduces the content file as an intermediary structure that stores section parameters and information about the crash dump file sections. This content file acts as a separate metadata layer that facilitates corruption detection without complicating the actual crash data collection process. The debugging administrator uses this intermediary file to compare against the actual crash dump sections, making corruption detection straightforward through parameter comparison.
Data Source
AI summary
Aspects pertaining to a crash dump file are described. In an example, the crash dump file may include one or more sections within which crash-related data is stored. A content file is also described which records valid parameters, wherein the valid section parameters pertain to corresponding sections within the crash dump file.
