Upstream-status: 3.13
From 4be402ba6158068d53ab0268f1affa9d82dae2ec Mon Sep 17 00:00:00 2001

Subject: [PATCH] inet: fix addr_len/msg->msg_namelen assignment in recv_error
and rxpmtu functions
Commit bceaa90240b6019ed73b49965eac7d167610be69 ("inet: prevent leakage
of uninitialized memory to user in recv syscalls") conditionally updated
addr_len if the msg_name is written to. The recv_error and rxpmtu
functions relied on the recvmsg functions to set up addr_len before.
As this does not happen any more we have to pass addr_len to those
functions as well and set it to the size of the corresponding sockaddr
length.
This broke traceroute and such.
Fixes: bceaa90240b6 ("inet: prevent leakage of uninitialized memory to user in recv syscalls")

Subject: [PATCH] inet: prevent leakage of uninitialized memory to user in recv
syscalls
Only update *addr_len when we actually fill in sockaddr, otherwise we
can return uninitialized memory from the stack to the caller in the
recvfrom, recvmmsg and recvmsg syscalls. Drop the the (addr_len == NULL)
checks because we only get called with a valid addr_len pointer either
from sock_common_recvmsg or inet_recvmsg.
If a blocking read waits on a socket which is concurrently shut down we
now return zero and set msg_msgnamelen to 0.
