-
-We must set the correct context (via eglMakeCurrent) before
-calling qemu_egl_create_context, so we need a thin wrapper and can't
-hook qemu_egl_create_context directly as ->dpy_gl_ctx_create callback.

-Subject: [PATCH] usb-mtp: use O_NOFOLLOW and O_CLOEXEC.
-
-Open files and directories with O_NOFOLLOW to avoid symlinks attacks.
-While being at it also add O_CLOEXEC.
-
-usb-mtp only handles regular files and directories and ignores
-everything else, so users should not see a difference.
-
-Because qemu ignores symlinks, carrying out a successful symlink attack
-requires swapping an existing file or directory below rootdir for a
-symlink and winning the race against the inotify notification to qemu.

-rdma back-end has scatter/gather array ibv_sge[MAX_SGE=4] set
-to have 4 elements. A guest could send a 'PvrdmaSqWqe' ring element
-with 'num_sge' set to > MAX_SGE, which may lead to OOB access issue.
