install.sh ran as root and created /tmp/aic8800d80_install.log with mode
666 at a fixed, predictable path. Root writing to a fixed name in /tmp is
open to symlink races (mitigated, not removed, by fs.protected_symlinks),
and a world-writable log lets any local user alter what an administrator
later reads.
The log now lives at /var/log/aic8800-install.log, is created with mode
0644 only after the root check, and failed writes before that point are
silenced instead of printing redirection errors. diagnostic_build.sh
reads the new path and falls back to the old one for logs left by
earlier installers.
(cherry picked from commit ef66811ca5)
Install Arch dependencies using the existing package database and explain how to recover from stale package metadata. Avoid errexit on the first firmware count, handle Secure Boot prompt EOF as cancellation, propagate error traps into functions, and reject empty firmware sources before modifying installed firmware.
Validation: eight isolated installer regression tests pass; the original installer fails the affected cases. Bash syntax and ShellCheck error-level checks pass. Fixes#100. Addresses the confirmed findings in #108; other audit suggestions remain separate.
Install mode-switch dependencies, support a69c:572f, avoid redundant generic headers when a usable kernel build tree exists, and discover DKMS logs dynamically. Addresses installer portions of #28, #55, #65, #66, and #68.
Follow-up to d66e5cb which shipped fw/aic8800{,D80N,D80X2,DLN} but
forgot to update install.sh — so users still got only aic8800D80
firmware installed and the "Pandora" mode-switch config was missing.
install_firmware:
- Loop over all fw/aic8800* variants instead of hard-coding aic8800D80
- Install usb_modeswitch/1111_1111 to /etc/usb_modeswitch.d/1111:1111
verify_installation: count installed firmware variants instead of
checking for the single aic8800D80 directory.
