Christoph Hellwig d418313bd8 block: initialize integrity buffer to zero before writing it to media ... [ Upstream commit 899ee2c382 ] Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory. Fix this by adding the __GFP_ZERO flag to allocations for writes. Fixes: 7ba1ba12ee ("block: Block layer data integrity support") Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.
