########## File path: libs/libc/netdb/lib_dnsaddserver.c ########## @@ -87,7 +87,7 @@ int dns_add_nameserver(FAR const struct sockaddr *addr, socklen_t addrlen) int status; int ret; - stream = fopen(CONFIG_NETDB_RESOLVCONF_PATH, "at"); + stream = fopen(CONFIG_NETDB_RESOLVCONF_PATH, "r"); Review comment: If user enable CONFIG_NETDB_RESOLVCONF, he/she should put resolv.conf in the writable filesystem by CONFIG_NETDB_RESOLVCONF_PATH. Surya report two problems: 1.Call open with "at": this is a typo bug we need fix DNS(change to "a+"). 2. Fail to open with "a+"/"w+" due to read-only ROMFS: this is invalid usage, Surya should modify his config. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
