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. - -diff --git a/gcc/c-family/c.opt b/gcc/c-family/c.opt -index f591b39be5a..cf922812198 100644 ---- a/gcc/c-family/c.opt -+++ b/gcc/c-family/c.opt -@@ -334,6 +334,30 @@ 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) -+; -+ -+Wbidi-chars= -+C ObjC C++ ObjC++ RejectNegative Joined Warning CPP(cpp_warn_bidirectional) CppReason(CPP_W_BIDIRECTIONAL) Var(warn_bidirectional) Init(bidirectional_unpaired) Enum(cpp_bidirectional_level) -+-Wbidi-chars=[none|unpaired|any] Warn about UTF-8 bidirectional control characters. -+ -+; Required for these enum values. -+SourceInclude -+cpplib.h -+ -+Enum -+Name(cpp_bidirectional_level) Type(int) UnknownError(argument %qs to %<-Wbidi-chars%> not recognized) -+ -+EnumValue -+Enum(cpp_bidirectional_level) String(none) Value(bidirectional_none) -+ -+EnumValue -+Enum(cpp_bidirectional_level) String(unpaired) Value(bidirectional_unpaired) -+ -+EnumValue -+Enum(cpp_bidirectional_level) String(any) Value(bidirectional_any) -+ - Wbool-compare - C ObjC C++ ObjC++ Var(warn_bool_compare) Warning LangEnabledBy(C ObjC C++ ObjC++,Wall) - Warn about boolean expression compared with an integer value different from true/false. -diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi -index 78ca7738df2..cc85c53aede 100644 ---- a/gcc/doc/invoke.texi -+++ b/gcc/doc/invoke.texi -@@ -264,7 +264,8 @@ Objective-C and Objective-C++ Dialects}. - -Walloc-zero -Walloc-size-larger-than=@var{n} - -Walloca -Walloca-larger-than=@var{n} @gol - -Wno-aggressive-loop-optimizations -Warray-bounds -Warray-bounds=@var{n} @gol ---Wno-attributes -Wbool-compare -Wbool-operation @gol -+-Wno-attributes -Wbidi-chars=@r{[}none@r{|}unpaired@r{|}any@r{]} @gol -+-Wbool-compare -Wbool-operation @gol - -Wno-builtin-declaration-mismatch @gol - -Wno-builtin-macro-redefined -Wc90-c99-compat -Wc99-c11-compat @gol - -Wc++-compat -Wc++11-compat -Wc++14-compat @gol -@@ -5606,6 +5607,23 @@ Warn about declarations using the @code{alias} and similar attributes whose - target is incompatible with the type of the alias. @xref{Function Attributes, - ,Declaring Attributes of Functions}. - -+@item -Wbidi-chars=@r{[}none@r{|}unpaired@r{|}any@r{]} -+@opindex Wbidi-chars= -+@opindex Wbidi-chars -+@opindex Wno-bidi-chars -+Warn about possibly misleading UTF-8 bidirectional control characters in -+comments, string literals, character constants, and identifiers.
