+From bcdd6a55952222ec9829a59348240a4f983b0b56 Mon Sep 17 00:00:00 2001
+From: Peter Jones <pjones@redhat.com>
+Date: Mon, 15 Jun 2020 12:26:01 -0400
+Subject: [PATCH 4/9] calloc: Use calloc() at most places
+
+This modifies most of the places we do some form of:
+
+ X = malloc(Y * Z);
+
+to use calloc(Y, Z) instead.
+
+Among other issues, this fixes:
+ - allocation of integer overflow in grub_png_decode_image_header()
+ reported by Chris Coulson,
+ - allocation of integer overflow in luks_recover_key()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_lvm_detect()
+ reported by Chris Coulson.
+
+Fixes: CVE-2020-14308

+From eb77d1ef65e25746acff43545f62a71360b15eec Mon Sep 17 00:00:00 2001
+From: Peter Jones <pjones@redhat.com>
+Date: Mon, 15 Jun 2020 12:28:27 -0400
+Subject: [PATCH 6/9] malloc: Use overflow checking primitives where we do
+ complex allocations
+
+This attempts to fix the places where we do the following where
+arithmetic_expr may include unvalidated data:
+
+ X = grub_malloc(arithmetic_expr);
+
+It accomplishes this by doing the arithmetic ahead of time using grub_add(),
+grub_sub(), grub_mul() and testing for overflow before proceeding.
+
+Among other issues, this fixes:
+ - allocation of integer overflow in grub_video_bitmap_create()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_png_decode_image_header()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_squash_read_symlink()
+ reported by Chris Coulson,
+ - allocation of integer overflow in grub_ext2_read_symlink()
+ reported by Chris Coulson,
+ - allocation of integer overflow in read_section_as_string()
+ reported by Chris Coulson.
+

+Subject: [PATCH 8/9] script: Avoid a use-after-free when redefining a function
+ during execution
+
+Defining a new function with the same name as a previously defined
+function causes the grub_script and associated resources for the
+previous function to be freed. If the previous function is currently
+executing when a function with the same name is defined, this results
+in use-after-frees when processing subsequent commands in the original
+function.
+
+Instead, reject a new function definition if it has the same name as
+a previously defined function, and that function is currently being
+executed. Although a behavioural change, this should be backwards
+compatible with existing configurations because they can't be
+dependent on the current behaviour without being broken.

+Subject: [PATCH 3/9] lvm: Add LVM cache logical volume handling
+
+The LVM cache logical volume is the logical volume consisting of the original
+and the cache pool logical volume. The original is usually on a larger and
+slower storage device while the cache pool is on a smaller and faster one. The
+performance of the original volume can be improved by storing the frequently
+used data on the cache pool to utilize the greater performance of faster
+device.
+
+The default cache mode "writethrough" ensures that any data written will be
+stored both in the cache and on the origin LV, therefore grub can be straight
+to read the original lv as no data loss is guarenteed.
+
+The second cache mode is "writeback", which delays writing from the cache pool
+back to the origin LV to have increased performance. The drawback is potential
+data loss if losing the associated cache device.
+
+During the boot time grub reads the LVM offline i.e. LVM volumes are not
+activated and mounted, hence it should be fine to read directly from original
+lv since all cached data should have been flushed back in the process of taking
+it offline.
+
+It is also not much helpful to the situation by adding fsync calls to the
+install code. The fsync did not force to write back dirty cache to the original
+device and rather it would update associated cache metadata to complete the
+write transaction with the cache device. IOW the writes to cached blocks still
+go only to the cache device.
+
+To write back dirty cache, as LVM cache did not support dirty cache flush per
+block range, there'no way to do it for file. On the other hand the "cleaner"
+policy is implemented and can be used to write back "all" dirty blocks in a
+cache, which effectively drain all dirty cache gradually to attain and last in
+the "clean" state, which can be useful for shrinking or decommissioning a
+cache. The result and effect is not what we are looking for here.
+
+In conclusion, as it seems no way to enforce file writes to the original
+device, grub may suffer from power failure as it cannot assemble the cache
+device and read the dirty data from it. However since the case is only
+applicable to writeback mode which is sensitive to data lost in nature, I'd
+still like to propose my (relatively simple) patch and treat reading dirty
+cache as improvement.

+Subject: [PATCH 5/9] safemath: Add some arithmetic primitives that check for
+ overflow
+
+This adds a new header, include/grub/safemath.h, that includes easy to
+use wrappers for __builtin_{add,sub,mul}_overflow() declared like:
+
+ bool OP(a, b, res)
+
+where OP is grub_add, grub_sub or grub_mul. OP() returns true in the
+case where the operation would overflow and res is not modified.
+Otherwise, false is returned and the operation is executed.
+
+These arithmetic primitives require newer compiler versions. So, bump
+these requirements in the INSTALL file too.
