x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32
 2019-05-30 15:37:58 -04:00
H.J. Lu 3dba7fbf84 x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32 
Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a

x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
R_X86_64_PC32.

Fix packed not aligned error on GCC 8
 2019-03-18 15:19:35 -04:00
Michael Chang 72841aeaa2 Fix packed-not-aligned error on GCC 8 
When building with GCC 8, there are several errors regarding packed-not-aligned.

./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]

This patch fixes the build error by cleaning up the ambiguity of placing
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
has to be packed, to ensure the structure is bit-to-bit mapped to the format
laid on disk. I think we could blame to copy and paste error here for the
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as
the name suggests. :)

Michael Marineau eb28d32081 gpt: write backup GPT first, skip if inaccessible. 
Writing the primary GPT before the backup may lead to a confusing
situation: booting a freshly updated system could consistently fail and
next boot will fall back to the old system if writing the primary works
but writing the backup fails. If the backup is written first and fails
the primary is left in the old state so the next boot will re-try and
possibly fail in the exact same way. Making that repeatable should make
it easier for users to identify the error.

Additionally if the firmware and OS disagree on the disk size, making
the backup inaccessible to GRUB, then just skip writing the backup.
When this happens the automatic call to `coreos-setgoodroot` after boot
will take care of repairing the backup.

Michael Marineau 7b25acebc3 gpt: read entries table at the same time as the header

Michael Marineau 753dd92013 gpt: be more careful about relocating backup header 
The header was being relocated without checking the new location is
actually safe. If the BIOS thinks the disk is smaller than the OS then
repair may relocate the header into allocated space, failing the final
validation check. So only move it if the disk has grown.

Additionally, if the backup is valid then we can assume its current
location is good enough and leave it as-is.

Michael Marineau 1d358a2061 gpt: prefer disk size from header over firmware 
The firmware and the OS may disagree on the disk configuration and size.
Although such a setup should be avoided users are unlikely to know about
the problem, assuming everything behaves like the OS. Tolerate this as
best we can and trust the reported on-disk location over the firmware
when looking for the backup GPT. If the location is inaccessible report
the error as best we can and move on.

Michael Marineau 72b178950d gpt: fix partition table indexing and validation 
Portions of the code attempted to handle the fact that GPT entries on

assumed the data could be indexed by the struct size directly. This
never came up because no utility uses a size larger than 128 bytes but
for the sake of safety we need to do this by the spec.

Matthew Garrett 3340fc72a6 Don't allocate a new address buffer if we receive multiple responses 
The current logic in the DNS resolution code allocates an address buffer
based on the number of addresses in the response packet. If we receive
multiple response packets in response to a single query packet, this means
that we will reallocate a new buffer large enough for only the addresses in
that specific packet, discarding any previous results in the process. Worse,
we still keep track of the *total* number of addresses resolved in response
to this query, not merely the number in the packet being currently processed.
Use realloc() rather than malloc() to avoid overwriting the existing data,
and allocate a buffer large enough for the total set of addresses rather
than merely the number in this specific response.

Michael Marineau 3d066264ac gpt: consolidate crc32 computation code 
The gcrypt API is overly verbose, wrap it up in a helper function to
keep this rather common operation easy to use.

Michael Marineau c26743a145 gpt: rename misnamed header location fields 
The header location fields refer to 'this header' and 'alternate header'

Michael Marineau f69a9e0fdc gpt: start new GPT module 
This module is a new implementation for reading GUID Partition Tables
which is much stricter than the existing part_gpt module and exports GPT
data directly instead of the generic grub_partition structure. It will
be the basis for modules that need to read/write/update GPT data.

The current code does nothing more than read and verify the table.

Colin Watson dec8c6a8ac Don't allow insmod when secure boot is enabled. 
Hi,

Fedora's patch to forbid insmod in UEFI Secure Boot environments is fine
as far as it goes.  However, the insmod command is not the only way that
modules can be loaded.  In particular, the 'normal' command, which
implements the usual GRUB menu and the fully-featured command prompt,
will implicitly load commands not currently loaded into memory.  This
permits trivial Secure Boot violations by writing commands implementing
whatever you want to do and pointing $prefix at the malicious code.

I'm currently test-building this patch (replacing your current
grub-2.00-no-insmod-on-sb.patch), but this should be more correct.  It
moves the check into grub_dl_load_file.

GRUB team is aware of following problems:
- Currently search and assembling multidevice abstractions scans
all the devices which can be slow.
- Cache isn't used correctly for video which results in slowness.
Open bugs and issues are captured in the VAS_EBOOT bug tracking system:
While these are bugs their solution has a potential of breaking more and more
seriously. So it was decided for 1.99 that they aren't fixed.

gcc-mips-linux-gnu, gcc-mipsel-linux-gnu, gcc-powerpc64-linux-gnu,
gcc-riscv64-linux-gnu, gcc-sparc64-linux-gnu, mingw-w64 and mingw-w64-tools.
* qemu, specifically the binary 'qemu-system-i386'
* xorriso 1.2.9 or later, for grub-mkrescue and grub-shell
More cross compiling toolchains can be found at the following trusted sites:

Prerequisites for running make-check successfully:
* qemu, specifically the binary "qemu-system-ARCH" where ARCH is the
architecture VAS_EBOOT has been built for; the "qemu-system" package on Debian
will install all needed qemu architectures
* OVMF, for EFI platforms (packages ovmf, ovmf-ia32, qemu-efi-arm, and
qemu-efi-aarch64)
* OpenBIOS, for ieee1275 platforms (packages openbios-ppc and openbios-sparc)
* xorriso 1.2.9 or later, for VasEBoot-mkrescue and VasEBoot-shell
* wamerican, for VasEBoot-fs-tester
* mtools, FAT tools for EFI platforms
* xfonts-unifont, for the functional tests
* swtpm-tools and tpm2-tools, for TPM2 key protector tests
* If running a Linux kernel the following modules must be loaded:
- fuse, loop
- btrfs, erofs, ext4, f2fs, fat, hfs, hfsplus, jfs, mac-roman, minix, nilfs2,
reiserfs, udf, xfs
- On newer kernels, the exfat kernel modules may be used instead of the
exfat FUSE filesystem
- Kernel version 6.12.x was the last series to include reiserfs support,
so later kernels will fail the reiser filesystem test.
* The following are Debian named packages required mostly for the full
suite of filesystem testing (but some are needed by other tests as well):
- btrfs-progs, dosfstools, e2fsprogs, erofs-utils, exfatprogs, exfat-fuse,
f2fs-tools, genromfs, hfsprogs, jfsutils, nilfs-tools, ntfs-3g,
reiserfsprogs, squashfs-tools, reiserfsprogs, udftools, xfsprogs, zfs-fuse
- exfat-fuse, if not using the exfat kernel module
- gzip, lzop, xz-utils
- attr, cpio, g++, gawk, parted, recode, tar, util-linux
Note that `make check' will run and many tests may complete successfully
with only a subset of these prerequisites. However, some tests may fail
due to missing prerequisites.
To build the documentation you'll need:
* texinfo, for the info and html documentation
* texlive, for building the dvi and pdf documentation (optional)

Note, that the autoconf 2.65 manual states that when using the --host argument
to configure, the --build argument should be specified as well. Not sending
--build, enters a compatibility mode that will be removed in the future.
Normally, for building a VAS_EBOOT on amd64 with tools to run on amd64 to
generate images to run on ARM, using your Linux distribution's
packaged cross compiler, the following would suffice:
./configure --target=arm-linux-gnueabihf --with-platform=efi

Security Policy
===============
To report a vulnerability see "Reporting a Vulnerability" below.
Security Incident Policy
========================
Security bug reports are treated with special attention and are handled
differently from normal bugs. In particular, security sensitive bugs are not
handled in public but in private. Information about the bug and access to it
is restricted to people in the security group, the individual engineers that
work on fixing it, and any other person who needs to be involved for organisational
reasons. The process is handled by the security team, which decides on the people
involved in order to fix the issue. It is also guaranteed that the person reporting
the issue has visibility into the process of fixing it. Any security issue gets
prioritized according to its security rating. The issue is opened up to the public
in coordination with the release schedule and the reporter.
Disclosure Policy
=================
Everyone involved in the handling of a security issue - including the reporter -
is required to adhere to the following policy. Any information related to
a security issue must be treated as confidential and only shared with trusted
partners if necessary, for example to coordinate a release or manage exposure
of clients to the issue. No information must be disclosed to the public before
the embargo ends. The embargo time is agreed upon by all involved parties. It
should be as short as possible without putting any users at risk.
Supported Versions
==================
Only the most recent version of the VAS_EBOOT is supported.
Reporting a Vulnerability
=========================
The security report should be encrypted with the PGP keys and sent to ALL email
addresses listed below. Every vulnerability report will be assessed within
72 hours of receiving it. If the outcome of the assessment is that the report
describes a security issue, the report will be transferred into an issue on the
internal vulnerability project for further processing. The reporter is updated
on each step of the process.
While there's currently no bug bounty program we appreciate every report.
