an array of pointer (in struct fdtab) rather than a pointer of pointers. Sadly for us, no, arrays and pointers are not equivalent from a memory perspective: while pointers from/to another address space can be consumed by kvm(3) to query for data in kernel space, arrays are more tricky, especially when their content is copied in userland: they are part of the copied struct. Address of array members are only valid in their own address space, in our case userland, which is (fortunately?) different from kernel space. This breaks the various kvm_read() calls that query for file descriptor information. Consequence: lsof(1) cannot print filedescriptor information (starting from 5.99.14), and silently ignores the errors, as using the userland fdtab (``dt'' variable) is not valid for kernel. Fix that by using the ``fd_dt'' member of struct filedes, which stores the address of the fdtab struct in kernel address space. Took a few hours to understand what was going on with lsof(1), hmmm. Luckily, fstat(1) uses the proper model (checked about 5min ago). Why lsof(1) decided not to log an error on kvm_read() is... a good question. Bump rev.
