3.2.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Ilan Tayari <ilant@xxxxxxxxxxxx>
commit b588479358ce26f32138e0f0a7ab0678f8e3e601 upstream.
commit 1a6509d99122 ("[IPSEC]: Add support for combined mode algorithms")
introduced aead. The function attach_aead kmemdup()s the algorithm
name during xfrm_state_construct().
However this memory is never freed.
Implementation has since been slightly modified in
commit ee5c23176fcc ("xfrm: Clone states properly on migration")
without resolving this leak.
This patch adds a kfree() call for the aead algorithm name.
Fixes: 1a6509d99122 ("[IPSEC]: Add support for combined mode algorithms")
