clean up the coreboot submodules
also bring the coreboot/next modules in line with the recent merge that did away with coreboot/dell7 the submodules for coreboot/haswell were still there, and have now been deleted; the haswell tree was used for the NRI patches, which were moved to /default some time ago Signed-off-by: Leah Rowe <leah@libreboot.org>m920qwip

Subject: [PATCH 1/1] g45/hw-gfx-gma-plls.adb: Make reference clock frequency
|
||||
configurable
|
||||
|
||||
Instead of assuming a 96 MHz reference clock frequency, use the value
|
||||
specified by the new INTEL_GMA_DPLL_REF_FREQ Kconfig. This defaults to
|
||||
96 MHz to preserve the existing behavior. An example of where this is
|
||||
needed is the DPLL_REF_SSCLK input, which will typically be 100 MHz
|
||||
to support LVDS spread spectrum clocking.

|
||||
Subject: [PATCH 1/1] extract_vmlinuz.c: Fix the bounds check on
|
||||
vmlinuz_header_{offset,size}
|
||||
|
||||
The check on vmlinuz_header_offset and vmlinuz_header_size is obviously
|
||||
wrong:
|
||||
|
||||
if (!vmlinuz_header_size ||
|
||||
kpart_data + vmlinuz_header_offset + vmlinuz_header_size >
|
||||
kpart_data) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
`kpart_data + some_unsigned_values` can obviously never be `> kpart_data`,
|
||||
unless something has overflowed! And `vmlinuz_header_offset` hasn't even
|
||||
been set yet (besides being initialized to zero)!
|
||||
|
||||
GCC will deduce that if the check didn't cause the function to bail, then
|
||||
vmlinuz_header_size (a uint32_t) must be "negative"; that is: in the range
|
||||
[2GiB,4GiB).
|
||||
|
||||
On platforms where size_t is 32-bits, this is *especially* broken.
|
||||
memcpy's size argument must be in the range [0,2GiB). Because GCC has
|
||||
proved that vmlinuz_header_size is higher than that, it will fail to
|
||||
compile:
|
||||
|
||||
host/lib/extract_vmlinuz.c:67:9: error: 'memcpy' specified bound between 2147483648 and 4294967295 exceeds maximum object size 2147483647 [-Werror=stringop-overflow=]
|
||||
|
||||
So, fix the check.
|
||||
|
||||
I can now say that what I suspect the original author meant to write would
|
||||
be the following patch, if `vmlinuz_header_offset` were already set:
|
||||
|
||||
-kpart_data + vmlinuz_header_offset + vmlinuz_header_size > kpart_data
|
||||
+now + vmlinuz_header_offset + vmlinuz_header_size > kpart_size
|
||||
|
||||
This hypothesis is supported by `now` not getting incremented by
|
||||
`kblob_size` the way it is for the keyblock and preamble sizes.
|
||||
|
||||
However, we can also see that even this "corrected" bounds check is
|
||||
insufficient: it does not detect the vmlinuz_header overflowing into
|
||||
kblob_data.
|
||||
|
||||
OK, so let's describe the fix:
|
||||
|
||||
Have a `*vmlinuz_header` pointer instead of a
|
||||
`uint64_t vmlinuz_header_offset`, to be more similar to all the other
|
||||
regions. With this change, the correct check becomes a simple
|
||||
|
||||
vmlinuz_header + vmlinuz_header_size > kblob_data
|
||||
|
||||
While we're at it, make some changes that could have helped avoid this in
|
||||
the first place:
|
||||
|
||||
- Add comments.
|
||||
- Calculate the vmlinuz_header offset right away, instead of waiting.
|
||||
- Go ahead and increment `now` by `kblob_size`, to increase regularity.

From 195f61375aeec9eec16604ec59f6eda2e6058cc1 Mon Sep 17 00:00:00 2001
|
||||
From: "Luke T. Shumaker" <lukeshu@lukeshu.com>
|

|
||||
Subject: [PATCH 1/1] extract_vmlinuz.c: Fix the bounds check on
|
||||
vmlinuz_header_{offset,size}
|
||||
|
||||
The check on vmlinuz_header_offset and vmlinuz_header_size is obviously
|
||||
wrong:
|
||||
|
||||
if (!vmlinuz_header_size ||
|
||||
kpart_data + vmlinuz_header_offset + vmlinuz_header_size >
|
||||
kpart_data) {
|
||||
return 1;
|
||||
}
|
||||
|
||||
`kpart_data + some_unsigned_values` can obviously never be `> kpart_data`,
|
||||
unless something has overflowed! And `vmlinuz_header_offset` hasn't even
|
||||
been set yet (besides being initialized to zero)!
|
||||
|
||||
GCC will deduce that if the check didn't cause the function to bail, then
|
||||
vmlinuz_header_size (a uint32_t) must be "negative"; that is: in the range
|
||||
[2GiB,4GiB).
|
||||
|
||||
On platforms where size_t is 32-bits, this is *especially* broken.
|
||||
memcpy's size argument must be in the range [0,2GiB). Because GCC has
|
||||
proved that vmlinuz_header_size is higher than that, it will fail to
|
||||
compile:
|
||||
|
||||
host/lib/extract_vmlinuz.c:67:9: error: 'memcpy' specified bound between 2147483648 and 4294967295 exceeds maximum object size 2147483647 [-Werror=stringop-overflow=]
|
||||
|
||||
So, fix the check.
|
||||
|
||||
I can now say that what I suspect the original author meant to write would
|
||||
be the following patch, if `vmlinuz_header_offset` were already set:
|
||||
|
||||
-kpart_data + vmlinuz_header_offset + vmlinuz_header_size > kpart_data
|
||||
+now + vmlinuz_header_offset + vmlinuz_header_size > kpart_size
|
||||
|
||||
This hypothesis is supported by `now` not getting incremented by
|
||||
`kblob_size` the way it is for the keyblock and preamble sizes.
|
||||
|
||||
However, we can also see that even this "corrected" bounds check is
|
||||
insufficient: it does not detect the vmlinuz_header overflowing into
|
||||
kblob_data.
|
||||
|
||||
OK, so let's describe the fix:
|
||||
|
||||
Have a `*vmlinuz_header` pointer instead of a
|
||||
`uint64_t vmlinuz_header_offset`, to be more similar to all the other
|
||||
regions. With this change, the correct check becomes a simple
|
||||
|
||||
vmlinuz_header + vmlinuz_header_size > kblob_data
|
||||
|
||||
While we're at it, make some changes that could have helped avoid this in
|
||||
the first place:
|
||||
|
||||
- Add comments.
|
||||
- Calculate the vmlinuz_header offset right away, instead of waiting.
|
||||
- Go ahead and increment `now` by `kblob_size`, to increase regularity.

||||
