Nathan Hartman bf91047f33 libc: Fix getrandom() bug: Didn't propagate read error ... * libs/libc/misc/lib_getrandom.c, in function getrandom(): We were assigning the return value of _NX_READ() to nbytes, a variable of the unsigned type size_t. Note that _NX_READ() resolves to either read() or nx_read(), both of which return the signed type ssize_t to indicate either the number of bytes read successfully (>= 0) or an error (< 0). Then we were testing for a negative size_t value, a condition that can never occur. The end result is that if an error occured in _NX_READ(), it would never be detected and getrandom() would return some large positive value. This bug is corrected by assigning the return value of _NX_READ() to a new local variable, ret, of size ssize_t.		2022-07-01 11:51:53 +08:00
