X-Git-Tag: exim-4_80_RC2~4 X-Git-Url: https://git.exim.org/exim.git/commitdiff_plain/542bc632dd2ab452f87e0304e3356534e49f71f3?hp=7390e768d82239b8dc6697379277c37c8c927b9d Second SPF fix, moved to where type is correct. De-initialised "type" var in stack declaration, so a repeat of this mistake would lead to an uninitialized variable usage warning which would have blocked the previous incorrect fix from being committed. --- diff --git a/src/src/lookups/dnsdb.c b/src/src/lookups/dnsdb.c index be090cf78..0bbc86a56 100644 --- a/src/src/lookups/dnsdb.c +++ b/src/src/lookups/dnsdb.c @@ -122,7 +122,7 @@ int size = 256; int ptr = 0; int sep = 0; int defer_mode = PASS; -int type = T_TXT; +int type; int failrc = FAIL; uschar *outsep = US"\n"; uschar *outsep2 = NULL; @@ -164,14 +164,6 @@ if (*keystring == '>') while (isspace(*keystring)) keystring++; } -/* SPF strings should be concatenated without a separator, thus make -it the default if not defined (see RFC 4408 section 3.1.3). -Multiple SPF records are forbidden (section 3.1.2) but are currently -not handled specially, thus they are concatenated with \n by default. */ - -if (type == T_SPF && outsep2 == NULL) - outsep2 = US""; - /* Check for a defer behaviour keyword. */ if (strncmpic(keystring, US"defer_", 6) == 0) @@ -206,8 +198,10 @@ if (strncmpic(keystring, US"defer_", 6) == 0) while (isspace(*keystring)) keystring++; } -/* If the keystring contains an = this must be preceded by a valid type name. */ +/* Figure out the "type" value if it is not T_TXT. +If the keystring contains an = this must be preceded by a valid type name. */ +type = T_TXT; if ((equals = Ustrchr(keystring, '=')) != NULL) { int i, len; @@ -255,6 +249,14 @@ if (type == T_PTR && keystring[0] != '<' && string_is_ip_address(keystring, NULL) != 0) sep = -1; +/* SPF strings should be concatenated without a separator, thus make +it the default if not defined (see RFC 4408 section 3.1.3). +Multiple SPF records are forbidden (section 3.1.2) but are currently +not handled specially, thus they are concatenated with \n by default. */ + +if (type == T_SPF && outsep2 == NULL) + outsep2 = US""; + /* Now scan the list and do a lookup for each item */ while ((domain = string_nextinlist(&keystring, &sep, buffer, sizeof(buffer)))
