            Bug ID: 33245
           Summary: nptl: error in internal cancellation syscall handling
           Product: glibc
           Version: 2.41
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nptl
          Assignee: unassigned at sourceware dot org
          Reporter: adhemerval.zanella at linaro dot org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The SYSCALL_CANCEL calls __syscall_cancel, which in turn
__internal_syscall_cancel with an 'int' argument instead of the expecting 'long
int'. I might cause issues on syscalls that might return values larger than
INT_MAX, such as copy_file_range [1].
