Miciah Masters 5832b84200 kubelet: parseResolvConf: Handle "search ." ... When parsing a resolv.conf file that has "search .", parseResolvConf should accept the "." entry verbatim. Before this commit, parseResolvConf unconditionally trimmed the "." suffix, which in the case of "." resulted in a "" entry (that is, the empty string). This empty entry could lead parseResolvConf to produce a resolv.conf file with "search ". Resolvers could fail to parse such a resolv.conf file from parseResolvConf, thus breaking DNS resolution in pods. After this commit, parseResolvConf accepts a resolv.conf file with "search ." and passes the "." entry through verbatim to produce a valid resolv.conf file. The "." suffix is still trimmed for any entry that does not solely comprise ".". Follow-up to commit a215a88d91. * pkg/kubelet/network/dns/dns.go (parseResolvConf): Handle a "." entry in the search path by copying it verbatim. * pkg/kubelet/network/dns/dns_test.go (TestParseResolvConf): Add a test case for "search .".		2022-04-12 15:39:31 -04:00
