LuLu silently prevents Homebrew downloads

[olivierlacan]

I've noticed that despite manually adding a custom rule (allow for /usr/local/bin/brew) for Homebrew’s brew executable, downloads triggered by Homebrew when installing or upgrading a dependency installed with it are blocked (silently) by LuLu and downloads can only proceed when LuLu is manually disabled.

I'm curious if anyone's found a way around this issue. I'm guessing it's caused by whichever process inside Homebrew actually deals with network connections not being adequately detected by LuLu.

Reproduction

• install Homebrew
• run brew install ffmpeg to for example attempt to download and install ffmpeg
• notice multiple failures to download reported by Homebrew
• disable LuLu
• run brew install ffmpeg again
• download and installation completes successfully

Could not reproduce:

$ brew install ffmpeg

brew started connections using one curl and two git-remote-http processes, make sure you don't have them blocked for some reason.

I ran "brew update" and it just kept on hanging in an unresponsive manner. I disabled LuLu and the command finished without issue.

I use homebrew all the time with no issue, there must be some rule in there that is blocking it. Maybe try a fresh install of LuLu

I'm having this same now. Lulu: v. 1.1.2 Homebrew: 2.1.6 Homebrew/homebrew-core: (git revision b639; last commit 2019-07-02)

I'll try reinstall later, but due to this, I'll lost all my rules? 🤔

Any findings on that? Facing the same issue in 2023 :D

Can you run: log stream --level debug --predicate="subsystem='com.objective-see.lulu'" from the Terminal and then run some brew commands (that are failing).

The log should show what/why they are being blocked. Please post any findings here, or email: [email protected]

Mahalo!

Might help someone in the future: I had the same issue, and I discovered (using log stream command) that curl was blocked.
