X509_STORE_CTX_init is documented upstream to allow a NULL store and has
logic to account for it. However, attempting to use such an
X509_STORE_CTX crashes in X509_verify_cert due to the
additional_untrusted logic we added.
Moreover, before that change, it still crashes because
X509_STORE_CTX_get1_issuer (the default get_issuer hook) assumes
ctx->ctx (the store) is non-null. This was also true in upstream but
later fixed in https://github.com/openssl/openssl/pull/6001. However,
without a store, there is no trust anchor, so this is not very useful.
Reject NULL stores in X509_STORE_CTX_init and remove the logic allowing
for a NULL one.
Thanks to Danny Halawi for catching this.
Update-Note: X509_STORE_CTX_init will now fail when the store is NULL,
rather than report success, only to crash later in X509_verify_cert.
Breakage should thus be limited to code which was passing in a NULL
store but never used the resulting X509_STORE_CTX.

Although extensions are accessible via X509_get_ext_d2i, OpenSSL's X509
object carries caches of a number of extensions. OpenSSL added accessors
for some of these in 1.1.0 (X509_get0_subject_key_id) and 1.1.1d (the
others), so mirror this. Note that, although they look like simpler
getters, the error-handling is tricky.
(For now I'm just looking to mirror OpenSSL's accessors and finally make
the structs opaque. Go's x509.Certificate structure also recognizes a
collection of built-in certificate fields, but error-handling is in the
parser. That could be one path out of this cached fields mess, at the
cost of making the parse operation do more work.)

Most asymmetric operations scale superlinearly, which makes them
potential DoS vectors. This (and other problems) are mitigated with
fixed sizes, like RSA-2048, P-256, or curve25519.
In older algorithms like RSA and DSA, these sizes are conventions rather
than well-defined algorithms. "Everyone" uses RSA-2048, but code which
imports an RSA key may see an arbitrary key size, possibly from an
untrusted source. This is commonly a public key, so we bound RSA key
sizes in check_modulus_and_exponent_sizes.
However, some applications import external private keys, and may need
tighter bounds. These typically parse the key then check the result.
However, parsing itself can perform superlinear work (RSA_check_key or
recovering the DSA public key).
This CL does the following:
- Rename check_modulus_and_exponent_sizes to rsa_check_public_key and
additionally call it from RSA_check_key.
- Fix a bug where RSA_check_key, on CRT-less keys, did not bound d, and
bound p and q before multiplying (quadratic).
- Our DSA verifier had stricter checks on q (160-, 224-, and 256-bit
only) than our DSA signer (multiple of 8 bits). Aligner the signer to
the verifier's checks.
- Validate DSA group sizes on parse, as well as priv_key < q, to bound
the running time.
Ideally these invariants would be checked exactly once at construction,
but our RSA and DSA implementations suffer from some OpenSSL's API
mistakes (https://crbug.com/boringssl/316), which means it is hard to
consistently enforce invariants. This CL focuses on the parser, but
later I'd like to better rationalize the freeze_private_key logic.

Update-Note: Some invalid or overly large RSA and DSA keys may
previously have been accepted that are now rejected at parse time. For
public keys, this only moves the error from verification to parsing. In
some private key cases, we would previously allow signing with those
keys, but the resulting signatures would not be accepted by BoringSSL
anyway. This CL makes us behave more consistently.

I tried to save space and use 32-bit GOT offsets since a GOT > 2GiB is
crazy. However, Clang's linker emits 64-bit relocations even for .long,
thus the four bytes following each offset get stomped. It mostly works
because the relocations are applied in order, thus the following
relocation gets stomped but is then processed and fixed. But there's
four bytes of stomp at the end which hits the module integrity hash,
which is fatal.
This could be fixed by adding four bytes of padding after the list of
offsets, but that's piling a hack on a hack. So this change just
switches to 64-bit offsets.

This change adds optional support for
- Armv8.3-A Pointer Authentication (PAuth) and
- Armv8.5-A Branch Target Identification (BTI)
features to the perl scripts.
Both features can be enabled with additional compiler flags.
Unless any of these are enabled explicitly there is no code change at
all.
The extensions are briefly described below. Please read the appropriate
chapters of the Arm Architecture Reference Manual for the complete
specification.
Scope
-----
This change only affects generated assembly code.
Armv8.3-A Pointer Authentication
--------------------------------
Pointer Authentication extension supports the authentication of the
contents of registers before they are used for indirect branching
or load.
PAuth provides a probabilistic method to detect corruption of register
values. PAuth signing instructions generate a Pointer Authentication
Code (PAC) based on the value of a register, a seed and a key.
The generated PAC is inserted into the original value in the register.
A PAuth authentication instruction recomputes the PAC, and if it matches
the PAC in the register, restores its original value. In case of a
mismatch, an architecturally unmapped address is generated instead.
With PAuth, mitigation against ROP (Return-oriented Programming) attacks
can be implemented. This is achieved by signing the contents of the
link-register (LR) before it is pushed to stack. Once LR is popped,
it is authenticated. This way a stack corruption which overwrites the
LR on the stack is detectable.
The PAuth extension adds several new instructions, some of which are not
recognized by older hardware. To support a single codebase for both pre
Armv8.3-A targets and newer ones, only NOP-space instructions are added
by this patch. These instructions are treated as NOPs on hardware
which does not support Armv8.3-A. Furthermore, this patch only considers
cases where LR is saved to the stack and then restored before branching
to its content. There are cases in the code where LR is pushed to stack
but it is not used later. We do not address these cases as they are not
affected by PAuth.
There are two keys available to sign an instruction address: A and B.
PACIASP and PACIBSP only differ in the used keys: A and B, respectively.
The keys are typically managed by the operating system.
To enable generating code for PAuth compile with
-mbranch-protection=<mode>:
- standard or pac-ret: add PACIASP and AUTIASP, also enables BTI
(read below)
- pac-ret+b-key: add PACIBSP and AUTIBSP
Armv8.5-A Branch Target Identification
--------------------------------------
Branch Target Identification features some new instructions which
protect the execution of instructions on guarded pages which are not
intended branch targets.
If Armv8.5-A is supported by the hardware, execution of an instruction
changes the value of PSTATE.BTYPE field. If an indirect branch
lands on a guarded page the target instruction must be one of the
BTI <jc> flavors, or in case of a direct call or jump it can be any
other instruction. If the target instruction is not compatible with the
value of PSTATE.BTYPE a Branch Target Exception is generated.
In short, indirect jumps are compatible with BTI <j> and <jc> while
indirect calls are compatible with BTI <c> and <jc>. Please refer to the
specification for the details.
Armv8.3-A PACIASP and PACIBSP are implicit branch target
identification instructions which are equivalent with BTI c or BTI jc
depending on system register configuration.
BTI is used to mitigate JOP (Jump-oriented Programming) attacks by
limiting the set of instructions which can be jumped to.
BTI requires active linker support to mark the pages with BTI-enabled
code as guarded. For ELF64 files BTI compatibility is recorded in the
.note.gnu.property section. For a shared object or static binary it is
required that all linked units support BTI. This means that even a
single assembly file without the required note section turns-off BTI
for the whole binary or shared object.
The new BTI instructions are treated as NOPs on hardware which does
not support Armv8.5-A or on pages which are not guarded.
To insert this new and optional instruction compile with
-mbranch-protection=standard (also enables PAuth) or +bti.
When targeting a guarded page from a non-guarded page, weaker
compatibility restrictions apply to maintain compatibility between
legacy and new code. For detailed rules please refer to the Arm ARM.
Compiler support
----------------
Compiler support requires understanding '-mbranch-protection=<mode>'
and emitting the appropriate feature macros (__ARM_FEATURE_BTI_DEFAULT
and __ARM_FEATURE_PAC_DEFAULT). The current state is the following:
-------------------------------------------------------
| Compiler | -mbranch-protection | Feature macros |
+----------+---------------------+--------------------+
| clang | 9.0.0 | 11.0.0 |
+----------+---------------------+--------------------+
| gcc | 9 | expected in 10.1+ |
-------------------------------------------------------
Available Platforms
------------------
Arm Fast Model and QEMU support both extensions.
https://developer.arm.com/tools-and-software/simulation-models/fast-modelshttps://www.qemu.org/
Implementation Notes
--------------------
This change adds BTI landing pads even to assembly functions which are
likely to be directly called only. In these cases, landing pads might
be superfluous depending on what code the linker generates.
Code size and performance impact for these cases would be negligble.
Interaction with C code
-----------------------
Pointer Authentication is a per-frame protection while Branch Target
Identification can be turned on and off only for all code pages of a
whole shared object or static binary. Because of these properties if
C/C++ code is compiled without any of the above features but assembly
files support any of them unconditionally there is no incompatibility
between the two.

Large memory models on x86-64 allow the code/data of a shared object /
executable to be larger than 2GiB. This is typically impossible because
x86-64 code frequently uses int32 offsets from RIP.
Consider the following program:
int getpid();
int main() {
return getpid();
}
This is turned into the following assembly under a large memory model:
.L0$pb:
leaq .L0$pb(%rip), %rax
movabsq $_GLOBAL_OFFSET_TABLE_-.L0$pb, %rcx
addq %rax, %rcx
movabsq $getpid@GOT, %rdx
xorl %eax, %eax
jmpq *(%rcx,%rdx) # TAILCALL
And, with relocations:
0: 48 8d 05 f9 ff ff ff lea -0x7(%rip),%rax # 0 <main>
7: 48 b9 00 00 00 00 00 movabs $0x0,%rcx
e: 00 00 00
9: R_X86_64_GOTPC64 _GLOBAL_OFFSET_TABLE_+0x9
11: 48 01 c1 add %rax,%rcx
14: 48 ba 00 00 00 00 00 movabs $0x0,%rdx
1b: 00 00 00
16: R_X86_64_GOT64 getpid
1e: 31 c0 xor %eax,%eax
20: ff 24 11 jmpq *(%rcx,%rdx,1)
We can see that, in the large memory model, function calls involve
loading the address of _GLOBAL_OFFSET_TABLE_ (using `movabs`, which
takes a 64-bit immediate) and then indexing into it. Both cause
relocations.
If we link the binary and disassemble we get:
0000000000001120 <main>:
1120: 48 8d 05 f9 ff ff ff lea -0x7(%rip),%rax # 1120 <main>
1127: 48 b9 e0 2e 00 00 00 movabs $0x2ee0,%rcx
112e: 00 00 00
1131: 48 01 c1 add %rax,%rcx
1134: 48 ba d8 ff ff ff ff movabs $0xffffffffffffffd8,%rdx
113b: ff ff ff
113e: 31 c0 xor %eax,%eax
1140: ff 24 11 jmpq *(%rcx,%rdx,1)
Thus the _GLOBAL_OFFSET_TABLE_ symbol is at 0x1120+0x2ee0 = 0x4000.
That's the address of the .got.plt section. But the offset “into” the
table is -0x40, putting it at 0x3fd8, in .got:
Idx Name Size VMA LMA File off Algn
18 .got 00000030 0000000000003fd0 0000000000003fd0 00002fd0 2**3
19 .got.plt 00000018 0000000000004000 0000000000004000 00003000 2**3
And, indeed, there's a dynamic relocation to setup that address:
OFFSET TYPE VALUE
0000000000003fd8 R_X86_64_GLOB_DAT getpid@GLIBC_2.2.5
Accessing data or BSS works the same: the address of the variable is
stored relative to _GLOBAL_OFFSET_TABLE_.
This is a bit of a pain because we want to delocate the module into a
single .text segment so that it moves through linking unaltered. If we
took the obvious path and built our own offset table then it would need
to contain absolute addresses, but they are only available at runtime
and .text segments aren't supposed to be run-time patched. (That's why
.rela.dyn is a separate segment.) If we use a different segment then
we have the same problem as with the original offset table: the offset
to the segment is unknown when compiling the module.
Trying to pattern match this two-step lookup to do extensive rewriting
seems fragile: I'm sure the compilers will move things around and
interleave other work in time, if they don't already.
So, in order to handle movabs trying to load _GLOBAL_OFFSET_TABLE_ we
define a symbol in the same segment, but outside of the hashed region of
the module, that contains the offset from that position to
_GLOBAL_OFFSET_TABLE_:
.boringssl_got_delta:
.quad _GLOBAL_OFFSET_TABLE_-.boringssl_got_delta
Then a movabs of $_GLOBAL_OFFSET_TABLE_-.Lfoo turns into:
movq .boringssl_got_delta(%rip), %destreg
addq $.boringssl_got_delta-.Lfoo, %destreg
This works because it's calculating
_GLOBAL_OFFSET_TABLE_ - got_delta + (got_delta - .Lfoo)
When that value is added to .Lfoo, as the original code will do, the
correct address results. Also it doesn't need an extra register because
we know that 32-bit offsets are sufficient for offsets within the
module.
As for the offsets within the offset table, we have to load them from
locations outside of the hashed part of the module to get the
relocations out of the way. Again, no extra registers are needed.

Update-Note: If an SSL_QUIC_METHOD is set, connections will now fail if
ALPN is not negotiated. This new behavior can be detected by checking
if the value of BORINGSSL_API_VERSION is greater than 10.

Reason codes 1000+N correspond to receiving an alert N from the peer,
rather than observing the corresponding error condition locally. This
has generally been a source of confusion for folks.
They were originally named like SSL_R_TLSV1_ALERT_DECRYPTION_FAILED, but
OpenSSL introduced a few without the "ALERT" token in
739a543ea863682f157e9aa0ee382367eb3d187c.
We then inadvertently carried the mistake over in
SSL_R_TLSV1_UNKNOWN_PSK_IDENTITY and SSL_R_TLSV1_CERTIFICATE_REQUIRED.
Fix all these to include the "ALERT" for consistency and make it
slightly less confusing. (Although perhaps it should have been
RECEIVED_ALERT or so.) Add compatibility #defines for the original
OpenSSL ones and SSL_R_TLSV1_CERTIFICATE_REQUIRED. The latter can be
removed when downstream code is fixed. The OpenSSL ones we'll probably
just leave around.
Update-Note: The renamed alerts will log slightly different strings, but
the constants used by external code are still there.

The CI should be set up to retain the Go module and build caches, so
we'll avoid downloading it multiple times. This avoids having to
replicate some code.
Update-Note: The tests now have a golang.org/x/crypto dependency. This
should be fetched transparently with Go modules. Monorepos with
different import path conventions may need to rewrite these imports.

clang-format now reorders includes. It used to simply sort within
blocks, but later it added a "regroup" option. The regroup option is a
bit aggressive and does not take into account our project headers being
referenced in <system/header.h> style. (It also won't be able to
recognize the header corresponding to the source file, but perhaps we
should drop that rule.)
For now, just revert it to Preserve.

We should probably ponder what to do about clang-format. That we
disagree on chains of && is a little annoying, but peppering the code
with clang-format off seems problematic.

gRPC are currently importing generate_build_files.py, injecting a
custom printer, and running into problems with the symlinks they set up
to make this work, as well as needing to delete duplicate generated
files.
53a5ad34c0/src/boringssl/gen_build_yaml.py (L130)https://boringssl-review.googlesource.com/c/boringssl/+/42164
Rather than layer on more hacks, add a JSON output to
generate_build_files.py. This outputs a sources.json file that folks
with especially custom builds can consume. (Looks like gRPC converts to
some home-grown YAML format which I imagine is further processed by some
other generator?) We can then add it to master-with-bazel's output.

This fixes a couple issues:
- Which libraries to use should be based on WIN32, not MSVC.
- Windows libraries can be specified by #pragma comment lines in the
source or by build dependencies. We specified #pragma lines in
source, but also have build dependencies in crypto_test, etc. The
latter was missing bssl.
The comment line should be sufficient, but being explicit is useful,
so fill in the missing one. This should help building with MINGW,
which is missing support for the usual Windows pragma.

Sadly, we need to roll this one back for now, at least until we've
cleared all the test failures it causes. This retains the other checks
in https://boringssl-review.googlesource.com/c/boringssl/+/41746. We're
only rolling back enforcement of the DEFAULT v1 encoding.

This is partially imported from upstream's
54dbf42398e23349b59f258a3dd60387bbc5ba13 which does something similar.
In doing so, remove the pkcs8->broken field, which is a remnant of some
parsing hacks we long since removed (PKCS8_set_broken). The immediate
motivation is, if this sticks, this would make it easier to detach
i2d_PKCS8_PRIV_KEY_INFO and d2i_PKCS8_PRIV_KEY_INFO from the old ASN.1
code.
Update-Note: Direct accesses of PKCS8_PRIV_KEY_INFO now need to use the
accessors. Code search suggests no one uses the fields. Even the
accessors are virtually unused (the one thing which uses it doesn't need
it).

Code which targets OpenSSL won't use EVP_parse_public_key. X509_PUBKEY
is fairly deeply tied to the old ASN.1 stack, but there's no reason for
i2d_PUBKEY and friends to be. Move them to crypto/evp and reimplement as
wrappers over our functions.
