Disallow use of DES encryption functions in new programs.

2018-06-29T14:53:18Z

The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt, ecb_crypt, and des_setparity should not be used in new programs, because they use the DES block cipher, which is unacceptably weak by modern standards. Demote all of them to compatibility symbols, and remove their prototypes from installed headers. cbc_crypt, ecb_crypt, and des_setparity were already compat symbols when glibc was configured with --disable-obsolete-rpc. POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT is defined, so this change also removes the definition of X_OPEN_CRYPT from . The entire "DES Encryption" section is dropped from the manual, as is the mention of AUTH_DES and FIPS 140-2 in the introduction to crypt.texi. The documentation of 'memfrob' cross-referenced the DES Encryption section, which is replaced by a hyperlink to libgcrypt, and while I was in there I spruced up the actual documentation of 'memfrob' and 'strfry' a little. It's still fairly jokey, because those functions _are_ jokes, but they do also have real use cases, so people trying to use them for real should have all the information they need. DES-based authentication for Sun RPC is also insecure and should be deprecated or even removed, but maybe that can be left as TI-RPC's problem.

conformtest: Fix XPG standard naming.

2017-04-27T20:29:35Z

The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4". That naming is misleading. _XOPEN_SOURCE_EXTENDED actually means XPG4.2, including UX-shaded interfaces. _XOPEN_SOURCE actually means XPG4, or XPG4.2 without UX-shaded interfaces. (Prior XPG versions also used _XOPEN_SOURCE, but without any versioning of the values of the macro, so XPG4.2 without UX-shaded interfaces is the only sensible set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without _XOPEN_SOURCE_EXTENDED defined.) This patch fixes the naming in the conform/ tests, so that what is now called XPG4 is changed to XPG42, and what is now called XPG3 is changed to XPG4. Tested for x86_64 (and verified the complete set of expectations is unchanged by the patch beyond the intended renaming). * conform/GlibcConform.pm (XPG4): Rename standard to XPG42.

conformtest: Correct some stdlib.h expectations for XPG3.

2016-05-13T17:26:04Z

This patch corrects some spurious conformtest stdlib.h expectations for XPG3 (not based on a full review of the expectations for that standard, so other issues may remain). Tested for x86_64 and x86. * conform/data/stdlib.h-data (a64l): Do not expect for [XPG3]. (ecvt): Likewise. (fcvt): Likewise. (gcvt): Likewise. (getsubopt): Likewise. (grantpt): Likewise.

conformtest: clean up POSIX expectations for stdlib.h, string.h.

2014-04-30T15:35:18Z

Continuing the series of patches to clean up conformtest expectations for "POSIX" (1995/6) based on review of the expectations against the standard, this patch cleans up expectations for stdlib.h and string.h. Tested x86_64; no new XFAILs needed. * conform/data/stdlib.h-data [POSIX] (stddef.h): Do not allow header inclusion. [POSIX] (limits.h): Likewise. [POSIX] (math.h): Likewise. [POSIX] (sys/wait.h): Likewise. * conform/data/string.h-data [POSIX || UNIX98] (strtok_r): Require function. [POSIX] (stddef.h): Do not allow header inclusion.

The header conformance testing code needed extending for XPG7. This exposed a few bugs in the headers. There are more changes to come.
