Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

38-39: Improve sentence structure and grammar.

The description of the keyctl backend needs grammatical improvements:

-`keyctl` is a secure backend leverages the Linux's kernel security key management system
-to store cryptographic keys securely in memory.
+`keyctl` is a secure backend that leverages the Linux kernel's security key management system
+to store cryptographic keys securely in memory.

98-105: Enhance the keyctl backend section.

The section needs some improvements:

1. Fix punctuation:

-cryptographic data such as passwords, private key, authentication tokens, etc
+cryptographic data such as passwords, private keys, authentication tokens, etc.

2. Consider adding:

• Setup instructions or prerequisites (e.g., required packages)
• Basic usage examples
• Any specific configuration requirements

Would you like me to help generate the additional documentation content?

32-32: LGTM!

The addition of keyctl to the list of GNU/Linux credential managers is appropriate and well-documented with a proper link to the kernel documentation.
