# creates inside its root-owned per-user storage area. That area is
# /var/cagefs/<prefix>/<user>/.cagefs/website/... on the host and is
# bind-mounted into the cage at /var/.cagefs/website/... — both views
# are accepted because libenter.enter_site() picks one or the other
# depending on whether it runs inside or outside the cage. The file
# itself is never a symlink, so we reject symlinks outright rather
# than canonicalizing with realpath. Without this gate the attacker
# controls both the env var WEBSITE_TOKEN_PATH and the file contents
# at that path; the file contents land in $TOKEN, which is embedded
# into the ssh remote command argv below and re-parsed by the remote
# shell — so shell metacharacters in the file would execute on the

# The -L/-f/prefix gate above is defense-in-depth, TOCTOU is not exploitable because the
# forwarded $TOKEN must still equal the legit on-disk bytes that the
# origin's cagefs.server reads with open(..., O_NOFOLLOW) from a
# uid-derived path (see find_website_by_token() in
# proxyexec/cagefs.server.c) — a swapped symlink redirects what we
# cat, never what the server reads, so a TOCTOU substitution can only
# replace the forwarded bytes with something that fails the server's
# constant-time comparison.

# token file was tampered with — refuse to forward it into the ssh
# remote command, where the remote shell would re-parse metacharacters.
# Use POSIX `case` rather than `[[ =~ ]]` because the wrapper is also
# invoked through `sh` (e.g. jenkins_tests/rpm_tests/p_cagefs/
# 939-environment_var-check.sh), and dash treats `[[` as a missing
# command — the regex form would falsely trip and exit the script.
