This change makes sure a data copy using copy_bytes() does not exceed the
max_bytes value when using COPY_HOLES and max_bytes stops before the next
data section.
But the directories are changed from /dev/loop/by-ref/ -> /dev/disk/by-loop-ref/
and /dev/loop/by-inode/ -> /dev/disk/by-loop-inode/.
As /dev/loop/ is used by losetup command for other purpose.
See issue #28475.
This effectively reverts commits 9915cc6086,
5022fab15f, and
c0d998248e.
This is supposed to be a help for compilers to apply optimizations on
functions where they can't determine whether they are const/pure on
their own. For static, local functions the compiler can do this on its
own easily however, hence the decoration with pure/const is just noise.
Let's drop it, and let the compiler to its thing better.
(Use it for exported functions, since compilers can't 'reach-over' into
other modules to determine if they are pure, except if LTO is used)
And refuse to parse fstab when 'fstab=no' is specified in the kernel
command line.
When 'fstab=no' is specified in the kernel command line, fstab-generator
does not parse fstab and will not create e.g. /boot or /efi mount entry
even if fstab contains entries for the mount points. However, gpt-auto
generator may parse fstab file, and adjust or ignore mounts for EFI or
XBOOTLDR partitions based on the fstab file.
This makes gpt-auto also ignore fstab entries if 'fstab=no' is set in
the kernel command line.
Add a macro to log all errors in the openssl 'thread error queue'.
This consolidates all the openssl-generated errors to return -EIO and log at
debug level.
Also add a 'invalid' test in test-openssl, to allow manual verification that
the openssl error(s) are logged.

is_device_node() calls lstat(), causing device node
symlinks under /dev/disk/ not being compared correctly
using devnode_same().
Fixes#28585
The count field indicates the number of elements in the pcrSelections field,
and the size of each elements is greater than 1 byte, so using sizeof() is
incorrect when verifying the count field is valid; instead ELEMENTSOF() should
be used.

Move the calculation of the sealed object policy hash out of the tpm2_seal()
function. Instead, callers of tpm2_seal() can directly call
tpm2_calculate_sealing_policy() and then provide the policy hash to
tpm2_seal().
Add functions to convert a PEM or pkey to TPM2B_PUBLIC, and functions to
convert TPM2B_PUBLIC to pkey or fingerprint.
Supports both RSA and ECC keys.
Add ECC support to some test-tpm2 tests, and tests to cover the newly added functions.
Add function to create openssl pkey from ECC curve and point, and function to
get curve id and x/y point from existing ECC pkey. Also add function to create
new ECC key for specified curve.
Also add DEFINE_TRIVIAL_CLEANUP_FUNC_FULL_MACRO() to handle case when func() is
a macro, not a function symbol; specifically in this case it is used for
OPENSSL_free() which is a macro.
Add function to generate an EVP_PKEY for a specific 'n' and 'e', and function
to get 'n' and 'e' values from existing RSA public key. Also add a function to
generate a new RSA key with a specified number of bits.
In order to allow users to specify expected PCR values, change the
tpm2_parse_pcr_argument() to parse the text argument into an array of
Tpm2PCRValue objects, which provide not only the selected PCR indexes, but also
(optionally) the hash algorithm and hash value for each PCR index.
An array of Tpm2PCRValue objects effectively replaces a TPML_PCR_SELECTION
object combined with an array of (properly ordered) TPM2B_DIGEST objects.
Also update tpm2_calculate_sealing_policy() pin parameter to boolean use_pin,
since the function does not need to know the pin value, only if a pin is being
used.
Move some function declarations lower down, below the Tpm2Context and
Tpm2Handle typedefs; later commits will reference the typedefs in some of the
functions, so the typedefs need to come first in the header.
This only moves the declarations, none of the declarations are modified.
Add a new struct that can represent a PCR index, hash, and value all
together. This replaces code (e.g. the tpm2_pcr_read() parameters) that
required using both a TPML_PCR_SELECTION as well as array of TPM2B_DIGEST
entries, which was difficult to correlate the selection hash/index to each
digest.
Older versions used CreatePrimary() to create a transient primary key to use
when creating a sealed data object. That was changed in v254 to use Create()
instead, which should result in the same transient key, but it seems some
hardware TPMs refuse to allow using Create() to generate primary keys.
This reverts to using CreatePrimary() to create primary key.
