+Subject: [PATCH] Refactor strtod parsing of NaN payloads.
+
+The nan* functions handle their string argument by constructing a
+NAN(...) string on the stack as a VLA and passing it to strtod
+functions.
+
+This approach has problems discussed in bug 16961 and bug 16962: the
+stack usage is unbounded, and it gives incorrect results in certain
+cases where the argument is not a valid n-char-sequence.
+
+The natural fix for both issues is to refactor the NaN payload parsing
+out of strtod into a separate function that the nan* functions can
+call directly, so that no temporary string needs constructing on the
+stack at all. 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.

+Subject: [PATCH] Fix nan functions handling of payload strings (bug 16961, bug
+ 16962).
+
+The nan, nanf and nanl functions handle payload strings by doing e.g.:
+
+ if (tagp[0] != '\0')
+ {
+ char buf[6 + strlen (tagp)];
+ sprintf (buf, "NAN(%s)", tagp);
+ return strtod (buf, NULL);
+ }
+
+This is an unbounded stack allocation based on the length of the
+argument. Furthermore, if the argument starts with an n-char-sequence
+followed by ')', that n-char-sequence is wrongly treated as
+significant for determining the payload of the resulting NaN, when ISO
+C says the call should be equivalent to strtod ("NAN", NULL), without
+being affected by that initial n-char-sequence. This patch fixes both
+those problems by using the __strtod_nan etc. functions recently
+factored out of strtod etc. for that purpose, with those functions
+being exported from libc at version GLIBC_PRIVATE.
+
+Tested for x86_64, x86, mips64 and powerpc.
+
+ [BZ #16961]
+ [BZ #16962]
+ * math/s_nan.c (__nan): Use __strtod_nan instead of constructing a
+ string on the stack for strtod.
+ * math/s_nanf.c (__nanf): Use __strtof_nan instead of constructing
+ a string on the stack for strtof.
+ * math/s_nanl.c (__nanl): Use __strtold_nan instead of
+ constructing a string on the stack for strtold.
+ * stdlib/Versions (libc): Add __strtof_nan, __strtod_nan and
+ __strtold_nan to GLIBC_PRIVATE.
+ * math/test-nan-overflow.c: New file.
+ * math/test-nan-payload.c: Likewise.
+ * math/Makefile (tests): Add test-nan-overflow and
+ test-nan-payload.
