2018-09-04Distinguish Element and Linker for ilist.Adin Scannell
Furthermore, allow for the specification of an ElementMapper. This allows a single "Element" type to exist on multiple inline lists, and work without having to embed the entry type. This is a requisite change for supporting a per-Inode list of Dirents. PiperOrigin-RevId: 211467497 Change-Id: If2768999b43e03fdaecf8ed15f435fe37518d163

We have been unnecessarily creating too many savable types implicitly. PiperOrigin-RevId: 206334201 Change-Id: Idc5a3a14bfb7ee125c4f2bb2b1c53164e46f29a8

2018-06-27Call mm.CheckIORange() when copying in IOVecs.Nicolas Lacasse
CheckIORange is analagous to Linux's access_ok() method, which is checked when copying in IOVecs in both lib/iov_iter.c:import_single_range() and lib/iov_iter.c:import_iovec() => fs/read_write.c:rw_copy_check_uvector(). gVisor copies in IOVecs via Task.SingleIOSequence() and Task.CopyInIovecs(). We were checking the address range bounds, but not whether the address is valid. To conform with linux, we should also check that the address is valid. For usual preadv/pwritev syscalls, the effect of this change is not noticeable, since we find out that the address is invalid before the syscall completes. For vectorized async-IO operations, however, this change is necessary because Linux returns EFAULT when the operation is submitted, but before it executes. Thus, we must validate the iovecs when copying them in. PiperOrigin-RevId: 202370092 Change-Id: I8759a63ccf7e6b90d90d30f78ab8935a0fcf4936
