From 945a87340240b70b3c579773c9481ca913d95a92 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Mon, 7 Jan 2019 10:30:59 -0500
Subject: [PATCH 02/63] dp.h: make format_guid() handle misaligned guid
pointers safely.
GCC 9 adds -Werror=address-of-packed-member, which causes us to see the
build error reported at
https://bugzilla.opensuse.org/show_bug.cgi?id=1120862 .
That bug report shows us the following:
In file included from dp.c:26:
dp.h: In function 'format_vendor_helper':
dp.h:120:37: error: taking address of packed member of 'struct <anonymous>' may result in an unaligned pointer value [-Werror=address-of-packed-member]
120 | format_guid(buf, size, off, label, &dp->hw_vendor.vendor_guid);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
dp.h:74:25: note: in definition of macro 'format_guid'
74 | _rc = efi_guid_to_str(guid, &_guidstr); \
| ^~~~
cc1: all warnings being treated as errors
This patch makes format_guid() use a local variable as a bounce buffer
in the case that the guid we're passed is aligned as chaotic neutral.
Note that this only fixes this instance and there may be others that bz
didn't show because it exited too soon, and I don't have a gcc 9 build
in front of me right now.

Date: Tue, 12 Jun 2018 14:36:20 -0400
Subject: [PATCH 03/39] Pacify some coverity nits.
Coverity has trouble tracking data flow sometimes, and believes that
sysfs_readlink() and read_sysfs_file() will sometimes return >= 0 when
the buffer has not been filled out. This changes the check to also test
for a NULL pointer, hopefully pacifying it.

Coverity doesn't realize that efi_well_known_guids is /actually/ an

From bd8fc0ebe86da82468b40a4998c3000819e73afe Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Tue, 12 Jun 2018 14:36:20 -0400
Subject: [PATCH 05/39] Promote _make_hd_dn() to make_hd_dn() and get rid of
the wrapper.
The wrapper is just hiding what the code's doing, and all the other code
around where we use it does the same thing anyway. This hopefully
convinces coverity we're not really dereferencing "buf" there unless
it's nonzero.

Subject: [PATCH 06/39] Try to convince covscan that sysfs_read_file() doesn't
leak on error.
Basically, covscan gets confused about some of our return paths and
doesn't think the error condition correlates with not having allocated
(or having freed) the ram we're using to pass the file data back.

Since commit c3c553d the fifth parameter of format_guid() is treated as
a const void *. The casting is unnecessary.

Subject: [PATCH 11/63] ucs2.h: fix logic that checks for UCS-2 string
termination
Currently the loop to count the lenght of the UCS-2 string ends if either
of the two bytes are 0, but 0 is a valid value for UCS-2 character codes.
So only break the loop when 0 is the value for both UCS-2 char bytes.

Subject: [PATCH 12/63] dp-message: fix efidp_ipv4_addr fields assignment
The efidp_ipv4_addr structure has some 4-byte array fields to store IPv4
addresses and network mask. But the efidp_make_ipv4() function wrongly
casts these as a char * before dereferencing them to store a value.
Instead, cast it to a uint32_t * so the 32-bit value is correctly stored.

Subject: [PATCH 15/39] Make a linux device root for SOC devices that use FDT.
Add parsing for FDT devices in sysfs. These devices have to use HD() or
File() because we don't have a way to express FDT nodes in a Device
Path.

Subject: [PATCH 16/39] If we can't parse part of the device link, skip it and
set DEV_ABBREV_ONLY
If we can't parse some part of the device symlink, we can't write a full
device path, but we can write an abbreviated HD() or File() path. So if
we've exausted all possibilities, skip to the next node, set
DEV_ABBREV_ONLY in the device's flags, and try parsing again. Then when
creator.c checks if that flag conflicts, it'll throw an error if it
does.

Date: Wed, 29 May 2019 10:11:24 -0400
Subject: [PATCH 21/63] Fix up efi_guid_cmp()'s alignment problem a different
way
With the prior fix for efi_guid_cmp()'s alignment issue, abicheck shows:
1 function with some indirect sub-type change:
[C]'function int efi_guid_cmp(void* const, void* const)' at <built-in>:34:1 has some indirect sub-type changes:
parameter 1 of type 'void* const' changed:
entity changed from 'void* const' to 'const efi_guid_t*'
type size hasn't changed
parameter 2 of type 'void* const' changed:
entity changed from 'void* const' to 'const efi_guid_t*'
type size hasn't changed
While this isn't a meaningful ABI difference in terms of linking, it is
definitely worse than having the type actually specified.
This patch changes the type back to the previous type, but also changes
the typedef to require a 1-byte alignment. This will guarantee that all
new builds of efi_guid_cmp() and related code have code generated in a
way that's compatible with any alignment, thus alleviating the issue.

Subject: [PATCH 28/39] abignore: work around an abidw bug
Some versions of abignore mistakenly treat brackets as section headers,
thus ignoring the rest of the stanza after them. It's fixed upstream,
but I don't have the newer version yet. Moving the braces to be after
the change-kind and other things works around the issue.

Subject: [PATCH 31/39] Fix another buggy fake acpi pci root driver
In this case, the platform driver that creates the PCI(e) root device
doesn't fill in its driver link, so we can't look up what driver is in
use - but since it's the root, it *really* doesn't matter. And in
general, we only really care if it's the last node in our path, because
that'll be the controller for the boot device anyway.

Subject: [PATCH 34/63] Try to deal with some signof(char) != signof(uint8_t)
madness.
The 3-sign "char" type in C is so so painful sometimes. This attempts
to use -funsigned-char to avoid type-casting between (uint8_t *) and
(char *) quite so much. I'm not sure it'll pay off. The fact that
"char" is something that's not ever actually the same type as "unsigned
char" or "signed char" is still the absolute worst thing.
Why do we need signed char at all again?

From 73635c7e096eb36b52c1e874f9b76856c6a41228 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Mon, 17 Jun 2019 16:37:29 -0400
Subject: [PATCH 36/63] util.h: implement add()/mul()/sub() for more integer
types.
This adds the following:
uint_add()
uint_mul()
uint_sub()
long_sub()
ulong_sub()
Additionally it renames ulong_mult() to ulong_mul() and long_mult() to
long_mul().
As before, all of these are available without caring about the types,
as if declared:
bool add(TYPE addend, TYPE addend, TYPE *sum);
bool mul(TYPE factor, TYPE factor, TYPE *product);
bool sub(TYPE minuend, TYPE subtractahend, TYPE *difference);
If overflow would occur, the pointer target for the result is not
changed and the function returns true, otherwise it returns false.

Date: Tue, 18 Jun 2019 15:54:58 -0400
Subject: [PATCH 39/63] Fix a case clang-analyzer found where we may try to
parse a NULL
I don't think this is something that can *actually* happen - it didn't
trigger before save_variable() was added, and the save_variable() path
that calls this calls validate_name() immediately prior to this call.
validate_name() calls exit() if it's NULL. But that's weird as well,
because that's the same pattern all the other users of parse_name() use.
Anyway, this patch expands validate_name() and moves it into
parse_name() so we don't need to call it from everywhere when we're just
calling the two in a row anyway.

Date: Tue, 6 Aug 2019 09:22:25 -0700
Subject: [PATCH 40/63] Make sure makeguids helper is compiled for the host's
arch
Currently makeguids is compiled with the same flags/settings as the rest
of the package, which does not work in case of cross-compiles when arch
of the build host and the target host are different. Let's force
compiling for the native host arch to avoid this issue.
Note that this is not a full cross-compile solution as this does not
account for potential differences in host/target compilers (versions,
clang vs gcc, etc), but it removes one of the issue with package build
aborting due to invalid instruction on the host.

Subject: [PATCH 45/63] Make the top level makefile not parallelize.
Right now if you run:
make
make -j9 clean all
"clean" and "all" will run in parallel, and "all" will often finish
before "clean" will. This is obviously wrong.
This patch adds .NOTPARALLEL: at the top level, so none of the top-level
targets will parallelize, because we really never want that.

Subject: [PATCH 49/63] Rework some makefile bits to make overriding some
options simpler.
This reworks a lot of defaults.mk to make some variables more regularly
partially overridden on the command line, making e.g. suppression of
-Werror easier when warranted. It also makes having per-compiler
versions of each thing simpler.
The following variables can be overridden, though in some cases only
partially:
name kind of things in it
COMPILER gcc
CROSS_COMPILE arm-linux-gnu-
CC $(CROSS_COMPILE)$(COMPILER)
DEBUGINFO -g
OPTIMIZE -O2 -flto
WARNINGS -Wfoo -Wno-bar
ERRORS -Werror -Wno-error=cpp
CPPFLAGS -D and -I
CFLAGS $(OPTIMIZE) $(DEBUGINFO) $(WARNINGS) $(ERRORS)
LDFLAGS linker options (add-only)
CCLDFLAGS -Wl, prefixed linker options (add-only and it's
normally machine generated from LDFLAGS
HOSTCC $(COMPILER)
HOST_CPPFLAGS $(CPPFLAGS) (add-only)
HOST_CFLAGS $(CFLAGS) (add-only)
HOST_CCLDFLAGS $(CCLDFLAGS) (add-only)
This resolves issue #31

From 1b5da030b19e6f7f086ef2f1719159951c574fa7 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Tue, 15 Oct 2019 16:49:54 -0400
Subject: [PATCH 50/63] Make: add -Wno-missing-field-initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Ritchie wrote in '84:
If there are fewer initializers in the list than there are members of
the aggregate, then the aggregate is padded with 0's.
c99 §6.7.8 and c11 §6.7.9 each say:
10 If an object that has automatic storage duration is not initialized
explicitly, its value is indeterminate. If an object that has static
storage duration is not initialized explicitly, then:
— if it has pointer type, it is initialized to a null pointer;
— if it has arithmetic type, it is initialized to (positive or
unsigned) zero;
— if it is an aggregate, every member is initialized (recursively)
according to these rules;
— if it is a union, the first named member is initialized
(recursively) according to these rules.
...
21 If there are fewer initializers in a brace-enclosed list than there
are elements or members of an aggregate, or fewer characters in a
string literal used to initialize an array of known size than there
are elements in the array, the remainder of the aggregate shall be
initialized implicitly the same as objects that have static storage
duration.
This warning is thoroughly pointless.

If we know our log will only be seen by strace, the newlines don't add
anything to the strings but clutter.

From cb81253cc60d9641ee766fa2be691d82821710ca Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Tue, 15 Oct 2019 16:26:30 -0400
Subject: [PATCH 54/63] Improve consistency of debug prints
This changes debug prints in a couple of ways:
- always calls the path we're parsing "current" in the output
- always use ' not " for quoting in the debug output, so tools that
escape strings won't change the lenghts
- everything that parses "current" has a debug print after each parse
attempt and before returning.

Date: Fri, 11 Oct 2019 14:20:54 -0400
Subject: [PATCH 56/63] Try even harder to find disk device symlinks in sysfs.
Today's realization is that the thing encoded into the structure of
sysfs is, in the best case, the dependency graph of the makefile targets
to build a device driver.
In the case of nvme-fabric, or really wherever the kernel has
class_create() and device_create() in the same function, there's an
extra level of indirection.
Anyway, in this patch we stop pretending sysfs isn't completely absurd,
and just try adding "/device" in the middle of the driver symlink path,
until we actually either get ENOENT on the device symlink or find a
device symlink that actually has a driver symlink under it.

From fa9336914ef43d1a1dbc3384c8051362eea12cd7 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Tue, 15 Oct 2019 16:53:27 -0400
Subject: [PATCH 58/63] sysfs parsers: make all the /sys/block link parsers
work the same way
Apparently I wrote some of these one way and some the other, and the one
special case where everything was "current+sz" instead of some form of
"current += pos; sz += pos; ...; return sz;".
Make them all the same, where possible.
