Bug ID: 29304
Summary: mq_timedreceive does not handle 64 bit syscall return
correct for !__ASSUME_TIME64_SYSCALLS
Product: glibc
Version: 2.32
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: adhemerval.zanella at linaro dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
On the code path for builds without 64 bit time_t default syscall, the check to
fallback to 32 bit is wrong:
38 bool need_time64 = abs_timeout != NULL
39 && !in_time_t_range (abs_timeout->tv_sec);
40 if (need_time64)
41 {
42 int r = SYSCALL_CANCEL (mq_timedreceive_time64, mqdes, msg_ptr,
msg_len,
43 msg_prio, abs_timeout);
44 if (r == 0 || errno != ENOSYS)
45 return r;
46 __set_errno (EOVERFLOW);
47 return -1;
48 }
It should check if 'r >= 0'.
