-Before committing, I noticed that PR/32161 was marked as a dup of PR/32009, but my previous patch did not fix it. - -This alternative patch is better because it lets you just use CFLAGS_FOR_TARGET to set the compilation flags for libgcc. Since bootstrapped target libraries are never compiled with the native compiler, it makes little sense to use different flags for stage1 and later stages. And it also makes little sense to use a different variable than CFLAGS_FOR_TARGET. - -Other changes I had to do include: - -- moving the creation of default CFLAGS_FOR_TARGET from Makefile.am to configure.ac, because otherwise the BOOT_CFLAGS are substituted into CFLAGS_FOR_TARGET (which is "-O2 -g $(CFLAGS)") via $(CFLAGS). It is also cleaner this way though. - -- passing the right CFLAGS to configure scripts as exported environment variables - -I also stopped passing LIBCFLAGS to configure scripts since they are unused in the whole src tree. And I updated the documentation as H-P reminded me to do. - -Bootstrapped/regtested i686-pc-linux-gnu, will commit to 4.4 shortly.

Adversaries can leverage this to +encode source code for compilers accepting Unicode such that targeted +vulnerabilities are introduced invisibly to human reviewers." + +More info: +https://nvd.nist.gov/vuln/detail/CVE-2021-42574 +https://trojansource.codes/ + +This is not a compiler bug. However, to mitigate the problem, this patch +implements -Wbidi-chars=[none|unpaired|any] to warn about possibly +misleading Unicode bidirectional control characters the preprocessor may +encounter. + +The default is =unpaired, which warns about improperly terminated +bidirectional control characters; e.g. a LRE without its corresponding PDF. +The level =any warns about any use of bidirectional control characters. + +This patch handles both UCNs and UTF-8 characters. UCNs designating +bidi characters in identifiers are accepted since r204886. Then r217144 +enabled -fextended-identifiers by default. Extended characters in C/C++ +identifiers have been accepted since r275979. However, this patch still +warns about mixing UTF-8 and UCN bidi characters; there seems to be no +good reason to allow mixing them. + +We warn in different contexts: comments (both C and C++-style), string +literals, character constants, and identifiers. Expectedly, UCNs are ignored +in comments and raw string literals. The bidirectional control characters +can nest so this patch handles that as well. + +I have not included nor tested this at all with Fortran (which also has +string literals and line comments). + +Dave M. posted patches improving diagnostic involving Unicode characters. +This patch does not make use of this new infrastructure yet. + + PR preprocessor/103026 + +gcc/c-family/ChangeLog: + + * c.opt (Wbidi-chars, Wbidi-chars=): New option. + +gcc/ChangeLog: + + * doc/invoke.texi: Document -Wbidi-chars. + +libcpp/ChangeLog: + + * include/cpplib.h (enum cpp_bidirectional_level): New. + (struct cpp_options): Add cpp_warn_bidirectional. + (enum cpp_warning_reason): Add CPP_W_BIDIRECTIONAL. + * internal.h (struct cpp_reader): Add warn_bidi_p member + function. + * init.c (cpp_create_reader): Set cpp_warn_bidirectional. + * lex.c (bidi): New namespace. + (get_bidi_utf8): New function. + (get_bidi_ucn): Likewise. + (maybe_warn_bidi_on_close): Likewise. + (maybe_warn_bidi_on_char): Likewise. + (_cpp_skip_block_comment): Implement warning about bidirectional + control characters. + (skip_line_comment): Likewise. + (forms_identifier_p): Likewise. + (lex_identifier): Likewise. + (lex_string): Likewise. + (lex_raw_string): Likewise. + +gcc/testsuite/ChangeLog: + + * c-c++-common/Wbidi-chars-1.c: New test. + * c-c++-common/Wbidi-chars-2.c: New test. + * c-c++-common/Wbidi-chars-3.c: New test. + * c-c++-common/Wbidi-chars-4.c: New test. + * c-c++-common/Wbidi-chars-5.c: New test. + * c-c++-common/Wbidi-chars-6.c: New test. + * c-c++-common/Wbidi-chars-7.c: New test. + * c-c++-common/Wbidi-chars-8.c: New test. + * c-c++-common/Wbidi-chars-9.c: New test. + * c-c++-common/Wbidi-chars-10.c: New test. + * c-c++-common/Wbidi-chars-11.c: New test. + * c-c++-common/Wbidi-chars-12.c: New test. + * c-c++-common/Wbidi-chars-13.c: New test. + * c-c++-common/Wbidi-chars-14.c: New test. + * c-c++-common/Wbidi-chars-15.c: New test. + * c-c++-common/Wbidi-chars-16.c: New test. + * c-c++-common/Wbidi-chars-17.c: New test. + +CVE: CVE-2021-42574 +Upstream-Status: Backport [https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=51c500269bf53749b107807d84271385fad35628] +Signed-off-by: Pgowda <pgowda.cve@gmail.com> + +--- + gcc/c-family/c.opt | 24 ++ + gcc/doc/invoke.texi | 21 +- + gcc/testsuite/c-c++-common/Wbidi-chars-1.c | 12 + + gcc/testsuite/c-c++-common/Wbidi-chars-10.c | 27 ++ + gcc/testsuite/c-c++-common/Wbidi-chars-11.c | 13 + + gcc/testsuite/c-c++-common/Wbidi-chars-12.c | 19 + + gcc/testsuite/c-c++-common/Wbidi-chars-13.c | 17 + + gcc/testsuite/c-c++-common/Wbidi-chars-14.c | 38 ++ + gcc/testsuite/c-c++-common/Wbidi-chars-15.c | 59 +++ + gcc/testsuite/c-c++-common/Wbidi-chars-16.c | 26 ++ + gcc/testsuite/c-c++-common/Wbidi-chars-17.c | 30 ++ + gcc/testsuite/c-c++-common/Wbidi-chars-2.c | 9 + + gcc/testsuite/c-c++-common/Wbidi-chars-3.c | 11 + + gcc/testsuite/c-c++-common/Wbidi-chars-4.c | 188 +++++++++ + gcc/testsuite/c-c++-common/Wbidi-chars-5.c | 188 +++++++++ + gcc/testsuite/c-c++-common/Wbidi-chars-6.c | 155 ++++++++ + gcc/testsuite/c-c++-common/Wbidi-chars-7.c | 9 + + gcc/testsuite/c-c++-common/Wbidi-chars-8.c | 13 + + gcc/testsuite/c-c++-common/Wbidi-chars-9.c | 29 ++ + libcpp/include/cpplib.h | 18 +- + libcpp/init.c | 1 + + libcpp/internal.h | 7 + + libcpp/lex.c | 408 +++++++++++++++++++- + 23 files changed, 1315 insertions(+), 7 deletions(-) + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-1.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-10.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-11.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-12.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-13.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-14.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-15.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-16.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-17.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-2.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-3.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-4.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-5.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-6.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-7.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-8.c + create mode 100644 gcc/testsuite/c-c++-common/Wbidi-chars-9.c + +diff --git a/gcc/c-family/c.opt b/gcc/c-family/c.opt +index 8a4cd634f77..3976fc368db 100644 +--- a/gcc/c-family/c.opt ++++ b/gcc/c-family/c.opt +@@ -370,6 +370,30 @@ Wbad-function-cast + C ObjC Var(warn_bad_function_cast) Warning + Warn about casting functions to incompatible types. + ++Wbidi-chars ++C ObjC C++ ObjC++ Warning Alias(Wbidi-chars=,any,none) ++;
