From 31b2ba1e0a7c419327cb97f589b508d78b9aecbf Mon Sep 17 00:00:00 2001 From: Travis Snoozy Date: Tue, 28 Mar 2023 03:36:46 -0700 Subject: [PATCH] Tell dnsmasq not to pass requests upstream (#223) * Tell dnsmasq not to pass requests upstream The behavior of dnsmasq changed in version 2.86 -- before then, if a record was set for a domain name with dnsmasq, and a record for a type not specified for that domain was requested, dnsmasq would indicate no data existed for that record type. After 2.86, record types that are not specified are instead passed upstream. The latter behavior causes problems for, e.g., the Steam client, which will disregard a correctly set A-record for lancache.steamcontent.com, if no AAAA is set with dnsmasq and dnsmasq passes the AAAA query upstream. The documentation for dnsmasq indicates the correct way to restore the old behavior is to use the local=/host/ syntax -- emit this syntax for each of our lancache-hosted DNS entries. * Update scripts/create-dnsmasq.sh Co-authored-by: Amir Zarrinkafsh --------- Co-authored-by: Amir Zarrinkafsh --- scripts/create-dnsmasq.sh | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/scripts/create-dnsmasq.sh b/scripts/create-dnsmasq.sh index 756cf2a..46483ac 100755 --- a/scripts/create-dnsmasq.sh +++ b/scripts/create-dnsmasq.sh @@ -52,10 +52,12 @@ while read -r entry; do fi parsed=$(echo ${fileentry} | sed -e "s/^\*\.//") for i in ${cacheip}; do - if grep -qx "address=/${parsed}/${i}" "${outputfile}"; then - continue + if ! grep -qx "address=/${parsed}/${i}" "${outputfile}"; then + echo "address=/${parsed}/${i}" >> "${outputfile}" + fi + if ! grep -qx "local=/${parsed}/" "${outputfile}"; then + echo "local=/${parsed}/" >> "${outputfile}" fi - echo "address=/${parsed}/${i}" >> "${outputfile}" done done <<< $(cat ${basedir}/${filename} | sort); done <<< $(jq -r ".cache_domains[${entry}].domain_files[$fileid]" ${path})
