The async path cannot use MAY_BACKLOG because it is not meant to
block, which is what MAY_BACKLOG does. On the other hand, both
the sync and async paths can make use of MAY_SLEEP.Cc: stable@vger.kernel.org

Any access to non-constant bits of the private context must be
done under the socket lock, in particular, this includes ctx->req.This patch moves such accesses under the lock, and fetches the
tfm from the parent socket which is guaranteed to be constant,
rather than from ctx->req.Cc: stable@vger.kernel.org

The async path in algif_skcipher assumes that the crypto completion
function will be called with the original request. This is not
necessarily the case. In fact there is no need for this anyway
since we already embed information into the request with struct
skcipher_async_req.This patch adds a pointer to that struct and then passes it as
the data to the callback function.Cc: stable@vger.kernel.org

We miss to take the crypto_alg_sem semaphore when traversing the
crypto_alg_list for CRYPTO_MSG_GETALG dumps. This allows a race with
crypto_unregister_alg() removing algorithms from the list while we're
still traversing it, thereby leading to a use-after-free as show below:[ 3482.071639] general protection fault: 0000 [#1] SMP

technical documents, and has this pearl of wisdom to offer:---------------------------------
Authenticode-Specific SignerInfo UnauthenticatedAttributes StructuresThe following Authenticode-specific data structures are present in
SignerInfo authenticated attributes.SpcSpOpusInfo
SpcSpOpusInfo is identified by SPC_SP_OPUS_INFO_OBJID
(1.3.6.1.4.1.311.2.1.12) and is defined as follows:
SpcSpOpusInfo ::= SEQUENCE {
programName [0] EXPLICIT SpcString OPTIONAL,
moreInfo [1] EXPLICIT SpcLink OPTIONAL,
} --#public--SpcSpOpusInfo has two fields:
programName
This field contains the program description:
If publisher chooses not to specify a description, the SpcString
structure contains a zero-length program name.
If the publisher chooses to specify a
description, the SpcString structure contains a Unicode string.
moreInfo
This field is set to an SPCLink structure that contains a URL for
a Web site with more information about the signer. The URL is an
ASCII string.
---------------------------------Which is to say that this is an optional *unauthenticated* field which
may be present in the Authenticated Attribute list. This is not how
pkcs7 is supposed to work, so when David implemented this, he didn't
appreciate the subtlety the original spec author was working with, and
missed the part of the sublime prose that says this Authenticated
Attribute is an Unauthenticated Attribute. As a result, the code in
question simply takes as given that the Authenticated Attributes should
be authenticated.But this one should not, individually. Because it says it's not
authenticated.It still has to hash right so the TBS digest is correct. So it is both
authenticated and unauthenticated, all at once. Truly, a wonder of
technical accomplishment.Additionally, pesign's implementation has always attempted to be
compatible with the signatures emitted from contemporary versions of
Microsoft's signtool.exe. During the initial implementation, Microsoft
signatures always produced the same values for SpcSpOpusInfo -
{U"Microsoft Windows", "http://www.microsoft.com"} - without regard to
who the signer was.Sometime between Windows 8 and Windows 8.1 they stopped including the
field in their signatures altogether, and as such pesign stopped
producing them in commits c0c4da6 and d79cb0c, sometime around June of
2012. The theory here is that anything that breaks with
pesign signatures would also be breaking with signtool.exe sigs as well,
and that'll be a more noticed problem for firmwares parsing it, so it'll
get fixed. The fact that we've done exactly this bug in Linux code is
first class, grade A irony.So anyway, we should not be checking this field for presence or any
particular value: if the field exists, it should be at the right place,
but aside from that, as long as the hash matches the field is good.Signed-off-by: Peter Jones

We mark the end of the SG list in sendmsg and sendpage and unmark
it on the next send call. Unfortunately the unmarking in sendmsg
is off-by-one, leading to an SG list that is too short.Fixes: 0f477b655a52 ("crypto: algif - Mark sgl end at the end of data")

I don't think it makes sense for a module to have a soft dependency
on itself. This seems quite cyclic by nature and I can't see what
purpose it could serve.OTOH libcrc32c calls crypto_alloc_shash("crc32c", 0, 0) so it pretty
much assumes that some incarnation of the "crc32c" hash algorithm has
been loaded. Therefore it makes sense to have the soft dependency
there (as crc-t10dif does.)Cc: stable@vger.kernel.org

Each af_alg parent socket obtained by socket(2) corresponds to a
tfm object once bind(2) has succeeded. An accept(2) call on that
parent socket creates a context which then uses the tfm object.Therefore as long as any child sockets created by accept(2) exist
the parent socket must not be modified or freed.This patch guarantees this by using locks and a reference count
on the parent socket. Any attempt to modify the parent socket will
fail with EBUSY.Cc: stable@vger.kernel.org
