2014-02-14Split up rules for tests that compare output with baselines.Joseph Myers
This patch splits makefile rules that generate a file then run cmp to check the contents of that file into separate rules to generate and compare the file. This simplifies making those tests generate PASS / FAIL results, by removing the need to insert && between commands in the test so that a $(evaluate-test) call is reached. It also avoids the oddity of the .out file being an intermediate file rather than the final result generated, as noted for some of these tests in <https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>. In many cases, the rule to run the program was no longer needed because the default rules for running test programs on the host to generate a .out file sufficed. (I'm not asserting the commands run after this patch are *exactly* the same as before, simply that the rules did nothing special that appeared deliberate or relevant to anything about what the tests were testing. In cases where the rules redirected stderr as well as stdout, I left the existing rule's redirection in place to avoid changing what gets compared with the expected results.) It's clear there is a lot in common between the various -cmp.out rules and it might be possible in future to refactor them into more generic support for the case of comparing test output against a baseline. (Some baselines are *.exp, some *.expect, some directly embedded in the makefiles, and nptl/tst-cleanupx0.expect appears unused.) Tested x86_64. * elf/Makefile ($(objpfx)order.out): Remove rule.

2014-02-13Clean up trivially redundant __USE_MISC conditionals.Joseph Myers
This patch cleans up cases of __USE_MISC that are trivially redundant after the recent substitution of __USE_MISC for __USE_BSD and __USE_SVID: either in constructs such as "defined __USE_MISC || defined __USE_MISC", or else (in the bits/mman.h case) a conditional on __USE_MISC nested inside another __USE_MISC conditional. (The cleanups remaining after this patch are still quite large, but it seems a reasonable piece to separate out.) Tested x86_64. * bits/mman.h [__USE_MISC]: Remove redundant conditionals. * ctype/ctype.h [__USE_MISC]: Likewise. * dirent/dirent.h [__USE_MISC]: Likewise. * grp/grp.h [__USE_MISC]: Likewise. * io/fcntl.h [__USE_MISC]: Likewise. * io/sys/stat.h [__USE_MISC]: Likewise. * libio/stdio.h [__USE_MISC]: Likewise. * posix/unistd.h [__USE_MISC]: Likewise. * pwd/pwd.h [__USE_MISC]: Likewise. * stdlib.h [__USE_MISC]: Likewise. * string/bits/string2.h [__USE_MISC]: Likewise. * string/string.h [__USE_MISC]: Likewise. * time/time.h [__USE_MISC]: Likewise.
2014-02-12Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers
This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

2013-12-23Define __CORRECT_ISO_CPP_STRING_H_PROTO correctly for Clang.Brooks Moses
In the string/string.h and string/strings.h headers, we have a couple of macros that "tell the caller that we provide correct C++ prototypes" according to the comment; they are used to determine whether to wrap some prototypes in "extern "C++"" (and provide multiple overloads of them, and some other magic) when __cplusplus is defined. The macros are set to check for sufficiently-recent GCC versions (4.4 and later), but this is not the right check for non-GCC compilers. In particular, these macros should also be set when using Clang -- if they are not set, then Clang will be unable to correctly diagnose a number of subtle bugs that will be errors in GCC compilations. As per discussion on earlier versions of this patch, rather than restrict the fix to Clang per se, we assume that all C++ compilers that claim to fully support C++98 are using a standard-conforming C++ standard library, which seems pretty reasonable. Clang has been providing an appropriate value of __cplusplus since May 2012.

2013-09-23Check for integer overflow in cache size computation in strcollSiddhesh Poyarekar
strcoll is implemented using a cache for indices and weights of collation sequences in the strings so that subsequent passes do not have to search through collation data again. For very large string inputs, the cache size computation could overflow. In such a case, use the fallback function that does not cache indices and weights of collation sequences. Fixes CVE-2012-4412.
2013-09-23Fall back to non-cached sequence traversal and comparison on malloc failSiddhesh Poyarekar
strcoll currently falls back to alloca if malloc fails, resulting in a possible stack overflow. This patch implements sequence traversal and comparison without caching indices and rules. Fixes CVE-2012-4424.
