error::pass5 - Linux

Overview

error::pass5 is a command-line utility used to analyze and report errors in Linux kernel code. Its primary purpose is to detect errors in the Linux kernel, assist developers in debugging, and ensure kernel stability. error::pass5 is a crucial tool for kernel developers and system administrators.

Syntax

error::pass5 [options] <error-file>...

where:

  • <error-file> is the path to the error file or log containing the kernel error messages.

Options/Flags

| Option | Default | Description |
|—|—|—|
| -m | false | Mark errors as examined |
| -ignore-attr | false | Ignore code attribute errors (e.g., lock contention) |
| -quick | false | Scan only for errors that can be matched against the database |
| -format | short | Output format: short, long, json, raw |
| -quiet | false | Suppress output of warnings and debug messages |

Examples

Simple usage to analyze a single error file:

error::pass5 kernel-log.txt

Mark errors as examined and ignore attribute errors:

error::pass5 -m -ignore-attr kernel-log.txt

Output errors in JSON format:

error::pass5 -format json kernel-log.txt

Common Issues

  • Permission errors: Ensure you have read permissions for the error file.
  • No errors found: Verify the error file contains kernel error messages.
  • Wrong format: The error file must be formatted as a Linux kernel error log.

Integration

error::pass5 can be integrated with other tools for advanced error analysis:

  • grep: Filter errors by specific keywords.
  • awk: Extract specific fields from error messages for further processing.
  • scripts: Automate error analysis tasks using custom scripts.

Related Commands

  • klogd: Collects and stores kernel error messages in a log file.
  • dmesg: Displays kernel error messages.
  • paniccheck: Analyzes and reports kernel panics.
