-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.

-Subject: [PATCH] slirp: check data length while emulating ident function
-
-While emulating identification protocol, tcp_emu() does not check
-available space in the 'sc_rcv->sb_data' buffer. It could lead to
-heap buffer overflow issue. Add check to avoid it.
