James Hilliard 96521aa5bc selftests/bpf: Fix conflicts with built-in functions in bpf_iter_ksym ... [ Upstream commit ab0350c743 ] Both tolower and toupper are built in c functions, we should not redefine them as this can result in a build error. Fixes the following errors: progs/bpf_iter_ksym.c:10:20: error: conflicting types for built-in function 'tolower'; expected 'int(int)' [-Werror=builtin-declaration-mismatch] 10 | static inline char tolower(char c) | ^~~~~~~ progs/bpf_iter_ksym.c:5:1: note: 'tolower' is declared in header '<ctype.h>' 4 | #include <bpf/bpf_helpers.h> +++ |+#include <ctype.h> 5 | progs/bpf_iter_ksym.c:17:20: error: conflicting types for built-in function 'toupper'; expected 'int(int)' [-Werror=builtin-declaration-mismatch] 17 | static inline char toupper(char c) | ^~~~~~~ progs/bpf_iter_ksym.c:17:20: note: 'toupper' is declared in header '<ctype.h>' See background on this sort of issue: https://stackoverflow.com/a/20582607 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=12213 (C99, 7.1.3p1) "All identifiers with external linkage in any of the following subclauses (including the future library directions) are always reserved for use as identifiers with external linkage."
