Instead these architectures have suffixed syscalls that +always use a 64-bit time_t. In the case of the io_getevents syscall the +syscall has been replaced with the io_pgetevents_time64 syscall instead. + +This patch changes the io_getevents() function to use the correct +syscall based on the avaliable syscalls and the time_t size. We will +only use the new 64-bit time_t syscall if the architecture is using a +64-bit time_t. This is to avoid having to deal with 32/64-bit +conversions and relying on a 64-bit timespec struct on 32-bit time_t +platforms. As of Linux 5.3 there are no 32-bit time_t architectures +without __NR_io_getevents. In the future if a 32-bit time_t architecture +wants to use the 64-bit syscalls we can handle the conversion. + +This fixes build failures on 32-bit RISC-V. + +Signed-off-by: Alistair Francis <alistair.francis@wdc.com> + +Reviewed-by: Richard Levitte <levitte@openssl.org> +Reviewed-by: Paul Dale <paul.dale@oracle.com> +(Merged from https://github.com/openssl/openssl/pull/9819) +--- + engines/e_afalg.c | 16 ++++++++++++++++ + 1 file changed, 16 insertions(+) + +diff --git a/engines/e_afalg.c b/engines/e_afalg.c +index dacbe358cb..99516cb1bb 100644 +--- a/engines/e_afalg.c ++++ b/engines/e_afalg.c +@@ -125,7 +125,23 @@ static ossl_inline int io_getevents(aio_context_t ctx, long min, long max, + struct io_event *events, + struct timespec *timeout) + { ++#if defined(__NR_io_getevents) + return syscall(__NR_io_getevents, ctx, min, max, events, timeout); ++#elif defined(__NR_io_pgetevents_time64) ++ /* Let's only support the 64 suffix syscalls for 64-bit time_t. ++ * This simplifies the code for us as we don't need to use a 64-bit ++ * version of timespec with a 32-bit time_t and handle converting ++ * between 64-bit and 32-bit times and check for overflows. ++ */ ++ if (sizeof(timeout->tv_sec) == 8) ++ return syscall(__NR_io_pgetevents_time64, ctx, min, max, events, timeout, NULL); ++ else { ++ errno = ENOSYS; ++ return -1; ++ } ++#else ++# error "We require either the io_getevents syscall or __NR_io_pgetevents_time64." ++#endif + } + + static void afalg_waitfd_cleanup(ASYNC_WAIT_CTX *ctx, const void *key, +-- +2.26.2 + |
