git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull more overflow updates from Kees Cook: "The rest of the overflow changes for v4.18-rc1. This includes the explicit overflow fixes from Silvio, further struct_size() conversions from Matthew, and a bug fix from Dan. But the bulk of it is the treewide conversions to use either the 2-factor argument allocators (e.g. kmalloc(a * b, ...) into kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a * b) into vmalloc(array_size(a, b)). Coccinelle was fighting me on several fronts, so I've done a bunch of manual whitespace updates in the patches as well.

2018-06-12treewide: Use array_size() in kvzalloc_node()Kees Cook
The kvzalloc_node() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: kvzalloc_node(a * b, gfp, node) with: kvzalloc_node(array_size(a, b), gfp, node) as well as handling cases of: kvzalloc_node(a * b * c, gfp, node) with: kvzalloc_node(array3_size(a, b, c), gfp, node) This does, however, attempt to ignore constant size factors like: kvzalloc_node(4 * 1024, gfp, node) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kvzalloc_node( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kvzalloc_node( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( kvzalloc_node( - sizeof(u8) * (COUNT) + COUNT , ...) | kvzalloc_node( - sizeof(__u8) * (COUNT) + COUNT , ...) | kvzalloc_node( - sizeof(char) * (COUNT) + COUNT , ...) | kvzalloc_node( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | kvzalloc_node( - sizeof(u8) * COUNT + COUNT , ...) | kvzalloc_node( - sizeof(__u8) * COUNT + COUNT , ...) | kvzalloc_node( - sizeof(char) * COUNT + COUNT , ...) | kvzalloc_node( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( kvzalloc_node( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ kvzalloc_node( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( kvzalloc_node( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | kvzalloc_node( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | kvzalloc_node( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( kvzalloc_node( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | kvzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | kvzalloc_node( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | kvzalloc_node( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | kvzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | kvzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( kvzalloc_node( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | kvzalloc_node( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( kvzalloc_node(C1 * C2 * C3, ...) | kvzalloc_node( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( kvzalloc_node(C1 * C2, ...) | kvzalloc_node( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>

There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms.

2018-06-11Revert "iommu/amd_iommu: Use CONFIG_DMA_DIRECT_OPS=y and ↵Linus Torvalds
dma_direct_{alloc,free}()" This reverts commit b468620f2a1dfdcfddfd6fa54367b8bcc1b51248. It turns out that this broke drm on AMD platforms. Quoting Gabriel C: "I can confirm reverting b468620f2a1dfdcfddfd6fa54367b8bcc1b51248 fixes that issue for me. The GPU is working fine with SME enabled. Now with working GPU :) I can also confirm performance is back to normal without doing any other workarounds" Christan König analyzed it partially: "As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs() in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled" and Christoph Hellwig responded: "I think the prime issue is that dma_direct_alloc respects the dma mask. Which we don't need if actually using the iommu. This would be mostly harmless exept for the the SEV bit high in the address that makes the checks fail. For now I'd say revert this commit for 4.17/4.18-rc and I'll look into addressing these issues properly" Reported-and-bisected-by: Gabriel C <nix.or.die@gmail.com> Acked-by: Christoph Hellwig <hch@lst.de> Cc: Christian König <christian.koenig@amd.com> Cc: Michel Dänzer <michel.daenzer@amd.com> Cc: Joerg Roedel <jroedel@suse.de> Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: stable@kernel.org # v4.17 Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

ntb_transport_create_queue ntb_transport_create_queue() is never called in atomic context. ntb_transport_create_queue() is only called by ntb_netdev_probe(), which is set as ".probe" in struct ntb_transport_client. Despite never getting called from atomic context, ntb_transport_create_queue() calls kzalloc_node() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation.
