[CIFS] Memory leak in ntlmv2 hash calculation
in function calc_ntlmv2_hash memory is not released. 1. If in the line 333 we successfully allocate memory and assign it to pctxt variable: pctxt = kmalloc(sizeof(struct HMACMD5Context), GFP_KERNEL); then we go to line 376 and exit wihout releasing memory pointed to by pctxt variable. Add a memory releasing for pctxt variable before exit from function calc_ntlmv2_hash. Signed-off-by: Alexander Strakh <strakh@ispras.ru> Signed-off-by: Steve French <sfrench@us.ibm.com>
