Again we have some odd side-effects when the ++ second response is NOTFOUND because we overwrite *errnop and ++ *h_errnop that means that a first answer of NOTFOUND might see ++ its *errnop and *h_errnop values altered. Whether it matters ++ in practice that a first response NOTFOUND has the wrong ++ *errnop and *h_errnop is undecided. ++ ++ [4] If the first response is UNAVAIL we return that instead of ++ looking at the second response. The expectation here is that ++ it will have failed similarly e.g. configuration failure. ++ ++ [5] Testing this code is complicated by the fact that truncated ++ second response buffers might be returned as SUCCESS if the ++ first answer is a SUCCESS.

If more than *ANSSIZP bytes are needed and ANSP2 ++ is non-NULL (required for a second query) then malloc is used to ++ allocate a new response buffer, *ANSSIZP2 is set to the new buffer ++ size and *ANSP2_MALLOCED is set to 1. ++ ++ The ANSP2_MALLOCED argument will eventually be removed as the ++ change in buffer pointer can be used to detect the buffer has ++ changed and that the caller should use free on the new buffer. ++ ++ Note that the answers may arrive in any order from the server and ++ therefore the first and second answer buffers may not correspond to ++ the first and second queries. ++ ++ It is not supported to call this function with a non-NULL ANSP2 ++ but a NULL ANSCP. Put another way, you can call send_vc with a ++ single unmodifiable buffer or two modifiable buffers, but no other ++ combination is supported. ++ ++ It is the caller's responsibility to free the malloc allocated ++ buffers by detecting that the pointers have changed from their ++ original values i.e. *ANSCP or *ANSP2 has changed. ++ ++ If an answer is truncated because of UDP datagram DNS limits then ++ *V_CIRCUIT is set to 1 and the return value non-zero to indicate to ++ the caller to retry with TCP. The value *GOTSOMEWHERE is set to 1 ++ if any progress was made reading a response from the nameserver and ++ is used by the caller to distinguish between ECONNREFUSED and ++ ETIMEDOUT (the latter if *GOTSOMEWHERE is 1). ++ ++ If errors are encountered then *TERRNO is set to an appropriate ++ errno value and a zero result is returned for a recoverable error, ++ and a less-than zero result is returned for a non-recoverable error. ++ ++ If no errors are encountered then *TERRNO is left unmodified and ++ a the length of the first response in bytes is returned. */ + static int + send_dg(res_state statp, + const u_char *buf, int buflen, const u_char *buf2, int buflen2, +@@ -1006,8 +1135,6 @@ send_dg(res_state statp, + { + const HEADER *hp = (HEADER *) buf; + const HEADER *hp2 = (HEADER *) buf2; +- u_char *ans = *ansp; +- int orig_anssizp = *anssizp; + struct timespec now, timeout, finish; + struct pollfd pfd[1]; + int ptimeout; +@@ -1040,6 +1167,8 @@ send_dg(res_state statp, + int need_recompute = 0; + int nwritten = 0; + int recvresp1 = 0; ++ /* Skip the second response if there is no second query. ++ To do that we mark the second response as received. */ + int recvresp2 = buf2 == NULL; + pfd[0].fd = EXT(statp).nssocks[ns]; + pfd[0].events = POLLOUT; +@@ -1203,55 +1332,56 @@ send_dg(res_state statp, + int *thisresplenp; + + if ((recvresp1 | recvresp2) == 0 || buf2 == NULL) { ++ /* We have not received any responses ++ yet or we only have one response to ++ receive. */ + thisanssizp = anssizp; + thisansp = anscp ?: ansp; + assert (anscp != NULL || ansp2 == NULL); + thisresplenp = &resplen; + } else { +- if (*anssizp != MAXPACKET) { +- /* No buffer allocated for the first +- reply.

This patch does that refactoring in preparation for +fixing those bugs (but without actually using the new functions from +nan* - which will also require exporting them from libc at version +GLIBC_PRIVATE). This patch is not intended to change any user-visible +behavior, so no tests are added (fixes for the above bugs will of +course add tests for them). + +This patch builds on my recent fixes for strtol and strtod issues in +Turkish locales. Given those fixes, the parsing of NaN payloads is +locale-independent; thus, the new functions do not need to take a +locale_t argument. + +Tested for x86_64, x86, mips64 and powerpc. + + * stdlib/strtod_nan.c: New file. + * stdlib/strtod_nan_double.h: Likewise. + * stdlib/strtod_nan_float.h: Likewise. + * stdlib/strtod_nan_main.c: Likewise. + * stdlib/strtod_nan_narrow.h: Likewise. + * stdlib/strtod_nan_wide.h: Likewise. + * stdlib/strtof_nan.c: Likewise. + * stdlib/strtold_nan.c: Likewise. + * sysdeps/ieee754/ldbl-128/strtod_nan_ldouble.h: Likewise. + * sysdeps/ieee754/ldbl-128ibm/strtod_nan_ldouble.h: Likewise. + * sysdeps/ieee754/ldbl-96/strtod_nan_ldouble.h: Likewise. + * wcsmbs/wcstod_nan.c: Likewise. + * wcsmbs/wcstof_nan.c: Likewise. + * wcsmbs/wcstold_nan.c: Likewise. + * stdlib/Makefile (routines): Add strtof_nan, strtod_nan and + strtold_nan. + * wcsmbs/Makefile (routines): Add wcstod_nan, wcstold_nan and + wcstof_nan. + * include/stdlib.h (__strtof_nan): Declare and use + libc_hidden_proto. + (__strtod_nan): Likewise. + (__strtold_nan): Likewise. + (__wcstof_nan): Likewise. + (__wcstod_nan): Likewise. + (__wcstold_nan): Likewise. + * include/wchar.h (____wcstoull_l_internal): Declare. + * stdlib/strtod_l.c: Do not include <ieee754.h>. + (____strtoull_l_internal): Remove declaration. + (STRTOF_NAN): Define macro. + (SET_MANTISSA): Remove macro. + (STRTOULL): Likewise. + (____STRTOF_INTERNAL): Use STRTOF_NAN to parse NaN payload. + * stdlib/strtof_l.c (____strtoull_l_internal): Remove declaration. + (STRTOF_NAN): Define macro. + (SET_MANTISSA): Remove macro. + * sysdeps/ieee754/ldbl-128/strtold_l.c (STRTOF_NAN): Define macro. + (SET_MANTISSA): Remove macro. + * sysdeps/ieee754/ldbl-128ibm/strtold_l.c (STRTOF_NAN): Define + macro. + (SET_MANTISSA): Remove macro. + * sysdeps/ieee754/ldbl-64-128/strtold_l.c (STRTOF_NAN): Define + macro. + (SET_MANTISSA): Remove macro. + * sysdeps/ieee754/ldbl-96/strtold_l.c (STRTOF_NAN): Define macro. + (SET_MANTISSA): Remove macro. + * wcsmbs/wcstod_l.c (____wcstoull_l_internal): Remove declaration. + * wcsmbs/wcstof_l.c (____wcstoull_l_internal): Likewise. + * wcsmbs/wcstold_l.c (____wcstoull_l_internal): Likewise. + +Upstream-Status: Backport +CVE: CVE-2015-9761 patch #1 +[Yocto # 8980] + +https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=e02cabecf0d025ec4f4ddee290bdf7aadb873bb3 + +Signed-off-by: Armin Kuster <akuster@mvista.com> + +--- + ChangeLog | 49 ++++++++++++++++++ + include/stdlib.h | 18 +++++++ + include/wchar.h | 3 ++ + stdlib/Makefile | 1 + + stdlib/strtod_l.c | 48 ++++-------------- + stdlib/strtod_nan.c | 24 +++++++++ + stdlib/strtod_nan_double.h | 30 +++++++++++ + stdlib/strtod_nan_float.h | 29 +++++++++++ + stdlib/strtod_nan_main.c | 63 ++++++++++++++++++++++++ + stdlib/strtod_nan_narrow.h | 22 +++++++++ + stdlib/strtod_nan_wide.h | 22 +++++++++ + stdlib/strtof_l.c | 11 +---- + stdlib/strtof_nan.c | 24 +++++++++ + stdlib/strtold_nan.c | 30 +++++++++++ + sysdeps/ieee754/ldbl-128/strtod_nan_ldouble.h | 33 +++++++++++++ + sysdeps/ieee754/ldbl-128/strtold_l.c | 13 +---- + sysdeps/ieee754/ldbl-128ibm/strtod_nan_ldouble.h | 30 +++++++++++ + sysdeps/ieee754/ldbl-128ibm/strtold_l.c | 10 +--- + sysdeps/ieee754/ldbl-64-128/strtold_l.c | 13 +---- + sysdeps/ieee754/ldbl-96/strtod_nan_ldouble.h | 30 +++++++++++ + sysdeps/ieee754/ldbl-96/strtold_l.c | 10 +--- + wcsmbs/Makefile | 1 + + wcsmbs/wcstod_l.c | 3 -- + wcsmbs/wcstod_nan.c | 23 +++++++++ + wcsmbs/wcstof_l.c | 3 -- + wcsmbs/wcstof_nan.c | 23 +++++++++ + wcsmbs/wcstold_l.c | 3 -- + wcsmbs/wcstold_nan.c | 30 +++++++++++ + 28 files changed, 504 insertions(+), 95 deletions(-) + create mode 100644 stdlib/strtod_nan.c + create mode 100644 stdlib/strtod_nan_double.h + create mode 100644 stdlib/strtod_nan_float.h + create mode 100644 stdlib/strtod_nan_main.c + create mode 100644 stdlib/strtod_nan_narrow.h + create mode 100644 stdlib/strtod_nan_wide.h + create mode 100644 stdlib/strtof_nan.c + create mode 100644 stdlib/strtold_nan.c + create mode 100644 sysdeps/ieee754/ldbl-128/strtod_nan_ldouble.h + create mode 100644 sysdeps/ieee754/ldbl-128ibm/strtod_nan_ldouble.h + create mode 100644 sysdeps/ieee754/ldbl-96/strtod_nan_ldouble.h + create mode 100644 wcsmbs/wcstod_nan.c + create mode 100644 wcsmbs/wcstof_nan.c + create mode 100644 wcsmbs/wcstold_nan.c + +Index: git/include/stdlib.h +=================================================================== +--- git.orig/include/stdlib.h ++++ git/include/stdlib.h +@@ -203,6 +203,24 @@ libc_hidden_proto (strtoll) + libc_hidden_proto (strtoul) + libc_hidden_proto (strtoull) + ++extern float __strtof_nan (const char *, char **, char) internal_function;

The + optimization is incorrect as implemented and because of that I'm + removing it for 2.23, and I will also commit this fix for 2.22 where + it was originally introduced. + + This patch reverts the optimization, introduces a new bug-strcoll2.c + regression test that tests both cs_CZ.UTF-8 and da_DK.ISO-8859-1 and + ensures they sort one digraph each correctly. The optimization can't be + applied without regressing this test. + + Checked on x86_64, bug-strcoll2.c fails without this patch and passes + after.
