Hi All,

We have observed memory leak with TCP network traffic in "newreno".

Output of vmstat -m

   in_mfilter     3     3K       -        3  1024
     in_multi     4     1K       -        4  256
  ip_moptions     6     1K       -        6  64,256
encap_export_host     2     2K       -        2  1024
 newreno data 394849273 6169520K       - 394849273  16
    sctp_a_it     0     0K       -        5  16
     sctp_vrf     1     1K       -        1  64
     sctp_ifa     7     1K       -        7  128
     sctp_ifn     4     1K       -        4  128

There is 1 malloc in "newreno_cb_init" whose pointer is not saved in any global structure to free the same.

Is this a BUG?
