   looking at another IP camera firmware and their ".bin" firmware format is just a zip archive with like u-boot.bin.img, uImage.img, and so on

   very convenient thank you 🙏

     it shortens the translation file names to "TradChinese" and "SimpChinese". phrasing

     fascinatingly, "English" and "ChineseEnglish" are separate locales!

     for some incomprehensible reason, this IP camera uses "Squirrel" http://www.squirrel-lang.org/, a programming language used essentially exclusively in the Source engine games

     it looks like they implemented motor control (zoom/panning) and RS485 comms in this language. there's functions that compute checksums and everything

     Ryan Castellucci :nonbinary_flag: repeated this.

     the partitions are interesting

     they're "Oops! All uImage!!"

     every single one of them is in the u-boot container. including u-boot itself. and its environment

     the cause of this becomes clear if you look at the u-boot environment: it's because of how it flashes itself

     so apparently the reason it tried to get me to downgrade the browser is because the interface to the IP camera is built as an ActiveX component and Chrome 44 is the last version which supported them

     i deobfuscated the JavaScript and it's ... literally just MooTools, an ancient JavaScript framework. think jQuery or something.

     so yes, literally this: https://mastodon.social/@easrng@pleroma.envs.net/114334884311562415

     the reason it reboots, by the way, is that under qemu-user, calling the reboot syscall straight up just reboots your machine

     (under qemu-system it reboots the VM, of course)

     @whitequark I’m a bit suprised you aren’t doing this in a VM.

     i don't believe it's _related_, but shortly after opening that page it hung Chrome and then when i ran `sudo dmesg` my laptop hard-rebooted for seemingly no reason

     i have the kernel save oops logs to pstore but it didn't do so, so it wasn't a kernel panic at least (or if it was, it panicked too hard to be able to use EFI runtime services...)

     the main binary of this IP camera works surprisingly well under qemu-arm-static, especially once after i gave it /dev/null in the chroot it lives in
