Revision 0f0909e242f73c1154272cf04f07fc9afe13e5b8 authored by Eric Biggers on 14 November 2016, 01:41:09 UTC, committed by Theodore Ts'o on 20 November 2016, 01:56:13 UTC
With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. get_crypt_info() was using a stack buffer to hold the output from the encryption operation used to derive the per-file key. Fix it by using a heap buffer. This bug could most easily be observed in a CONFIG_DEBUG_SG kernel because this allowed the BUG in sg_set_buf() to be triggered.
