jvoisin / fortify-headers Goto Github PK

16:49 <@q66> we'll need to go through all new fortifications you added and check them against libc headers
16:49 <@q66> following musl's headers is a good idea for this because afaik musl already tries to be the strictest in terms of what it makes available and when
16:50 <@q66> so in a "looser" libc you won't get a breakage but rather you'll just lose fortify for that one func

16:47 <@q66> e.g. fdopen needs to be behind
16:47 <@q66> #if defined(_POSIX_SOURCE) || defined(_POSIX_C_SOURCE) \
16:47 <@q66>  || defined(_XOPEN_SOURCE) || defined(_GNU_SOURCE) \
16:47 <@q66>  || defined(_BSD_SOURCE)
16:47 <@q66> but that's for a separate PR
16:48 <@q66> same with fmemopen etc
