From 4b4971c06fb02df00a2bd20b6b47b5d0e7d799a7 Mon Sep 17 00:00:00 2001 From: Tom Englund Date: Thu, 8 Aug 2024 21:01:50 +0200 Subject: internal: introduce new types to avoid unsigned int rollover and signed int overflow (#7216) * framebuffer: avoid gluint overflow GLuint was being initialized to -1 and rolling over to unsigned int max, its defined behaviour but very unnecessery. add a bool and use it for checking if allocated or not. * opengl: avoid gluint rollover -1 rolls over to unsigned int max, use 0xFF instead. * core: big uint64_t to int type conversion there were a few uint64_t to int implicit conversions overflowing int and causing UB, make all monitor/workspaces/windows use the new typedefs. also fix the various related 64 to 32 implicit conversions going around found with -Wshorten-64-to-32 --- src/signal-safe.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/signal-safe.cpp') diff --git a/src/signal-safe.cpp b/src/signal-safe.cpp index 05ca9c65..44d23f9b 100644 --- a/src/signal-safe.cpp +++ b/src/signal-safe.cpp @@ -10,7 +10,7 @@ extern char** environ; char const* sig_getenv(char const* name) { - int len = strlen(name); + size_t len = strlen(name); for (char** var = environ; *var != NULL; var++) { if (strncmp(*var, name, len) == 0 && (*var)[len] == '=') { return (*var) + len + 1; -- cgit v1.2.3
