[Qemu-devel] [PATCH v5 0/6] linux-user: Reorg interp_prefix handling

From: Richard Henderson
Subject: [Qemu-devel] [PATCH v5 0/6] linux-user: Reorg interp_prefix handling
Date: Thu, 31 May 2018 15:49:05 -0700

Changes since v4 (2018-01-28)
  * Protect host fds from guest manipulation.
  * Rename the interp_dirfd macro to TRY_INTERP_FD
  * Add TRY_INTERP_PATH for acct, statfs, inotify_add_watch

Changes since v3 (2017-12-29)
  * Use DO/WHILE as the control construct; wrap it in a macro.
  * Introduce linux_user_path to handle the cases *at syscalls
    do not cover.

Changes since v2 (2017-12-04)
  * Use IF as the control construct instead of SWITCH.

Changes since v1 (2016-11-??)
  * Require interp_dirfd set before trying the *at path.


Richard Henderson (6):
  gdbstub: Return the fd from gdbserver_start
  linux-user: Add host_fds and manipulators
  linux-user: Check is_hostfd in do_syscall
  linux-user: Check contains_hostfd in select syscalls
  linux-user: Check is_hostfd in mmap syscalls
  linux-user: Use *at functions to implement interp_prefix
