commit e861b44b93a6e14571bcc2f9d68b46ca8c44a734
Author: Oren Laadan <orenl@xxxxxxxxxxxxxxx>

Fix off-by-one buffer length passed to ckpt_write_string()
Reading and writing of strings expect the buffer length to include
the terminating NULL (reading will also enforce it). This patch
fixes the call from sock_unix_write_cwd() to include it.

commit ab84defe5b093ecec3a4a1abf2bc32f768e3205e
Author: Dan Smith <danms@xxxxxxxxxx>

Fix kfree() corruption in sock_read_buffer_sendmsg()
The memcpy_from_iovec() function that the unix sendmsg functions use modifies
the struct msghdr. Since the current code uses the msg.iovec_base pointer
in the msghdr for the kmalloc() and kfree(), we end up freeing the wrong
pointer. This patch stores the original address in a separate pointer and
corrects the kfree() call to use it.
