Daniel Bertalan	78e7ff008b	LibC: Fix negation overflow UB in sys/mman.cpp ... When the system calls return `NumericLimits<ptrdiff_t>::min()`, negating the return code would produce `NumericLimits<ptrdiff_t>::max() + 1` since we are on a two's complement architecture. Because this value cannot be stored, signed overflow occurs which is UB. This can be fixed by applying the negation to `EMAXERRNO` since that's known to contain a relatively small value. Found when running tests with Clang.	2021-08-08 10:55:36 +02:00
Luke	f5d4de8b66	LibC: Stub mlock in sys/mman ... mlock is supposed to prevent memory from being paged out to swap, which we don't have currently. Required by OpenSSL.	2021-07-30 20:49:56 +02:00
Jean-Baptiste Boric	eecf7a2097	LibC: Move mman.h to sys/mman.h ... POSIX mandates that it is placed there.	2021-05-14 22:24:02 +02:00
