Unlike algif_aead which is always issued in one go (thus limiting
the maximum size of the request), algif_skcipher has always allowed
unlimited input data by cutting them up as necessary and feeding
the fragments to the underlying algorithm one at a time.
However, because of deficiencies in the API, this has been broken
for most stream ciphers such as arc4 or chacha. This is because
they have an internal state in addition to the IV that must be
preserved in order to continue processing.
Fix this by using the new skcipher state API.

Remove ->sendpage() and ->sendpage_locked(). sendmsg() with
MSG_SPLICE_PAGES should be used instead. This allows multiple pages and

Make AF_ALG sendmsg() support MSG_SPLICE_PAGES. This causes pages to be
spliced from the source iterator.
This allows ->sendpage() to be replaced by something that can handle
multiple multipage folios in a single transaction.

I removed the MAY_BACKLOG flag on the aio path a while ago but
the error check still incorrectly interpreted EBUSY as success.
This may cause the submitter to wait for a request that will never

Pull crypto fix from Herbert Xu:
"This fixes a regression in af_alg"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: algif_aead - fix uninitialized ctx->init
|
|
In skcipher_accept_parent_nokey() the whole af_alg_ctx structure is
cleared by memset() after allocation, so add such memset() also to
aead_accept_parent_nokey() so that the new "init" field is also
initialized to zero. Without that the initial ctx->init checks might
randomly return true and cause errors.
While there, also remove the redundant zero assignments in both
functions.
Found via libkcapi testsuite.

AEAD does not support partial requests so we must not wake up
while ctx->more is set. In order to distinguish between the
case of no data sent yet and a zero-length request, a new init
flag has been added to ctx.
SKCIPHER has also been modified to ensure that at least a block
of data is available if there is more data to come.

The locking in af_alg_release_parent is broken as the BH socket
lock can only be taken if there is a code-path to handle the case
where the lock is owned by process-context. Instead of adding
such handling, we can fix this by changing the ref counts to
atomic_t.
This patch also modifies the main refcnt to include both normal
and nokey sockets. This way we don't have to fudge the nokey
ref count when a socket changes from nokey to normal.

When algif_skcipher does a partial operation it always process data
that is a multiple of blocksize. However, for algorithms such as
CTR this is wrong because even though it can process any number of
bytes overall, the partial block must come at the very end and not
in the middle.
This is exactly what chunksize is meant to describe so this patch
changes blocksize to chunksize.

The poll() changes were not well thought out, and completely
unexplained. They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.
Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead. That gets rid of one of the new indirections.
But that doesn't fix the new complexity that is completely unwarranted
for the regular case. The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.

The sock_kmalloc() function has no 2-factor argument form, so
multiplication factors need to be wrapped in array_size(). This patch
replaces cases of:
sock_kmalloc(handle, a * b, gfp)
with:
sock_kmalloc(handle, array_size(a, b), gfp)
as well as handling cases of:
sock_kmalloc(handle, a * b * c, gfp)
with:
sock_kmalloc(handle, array3_size(a, b, c), gfp)
This does, however, attempt to ignore constant size factors like:
sock_kmalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

Pull poll annotations from Al Viro:
"This introduces a __bitwise type for POLL### bitmap, and propagates
the annotations through the tree. Most of that stuff is as simple as
'make ->poll() instances return __poll_t and do the same to local
variables used to hold the future return value'.
Some of the obvious brainos found in process are fixed (e.g. POLLIN
misspelled as POLL_IN). At that point the amount of sparse warnings is
low and most of them are for genuine bugs - e.g. ->poll() instance
deciding to return -EINVAL instead of a bitmap. I hadn't touched those
in this series - it's large enough as it is.
Another problem it has caught was eventpoll() ABI mess; select.c and
eventpoll.c assumed that corresponding POLL### and EPOLL### were
equal. That's true for some, but not all of them - EPOLL### are
arch-independent, but POLL### are not.
The last commit in this series separates userland POLL### values from
the (now arch-independent) kernel-side ones, converting between them
in the few places where they are copied to/from userland. AFAICS, this
is the least disruptive fix preserving poll(2) ABI and making epoll()
work on all architectures.
As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
it will trigger only on what would've triggered EPOLLWRBAND on other
architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
at all on sparc. With this patch they should work consistently on all
architectures"

Similar to what was done for the hash API, update the skcipher API to
track whether each transform has been keyed, and reject
encryption/decryption if a key is needed but one hasn't been set.
This isn't as important as the equivalent fix for the hash API because
symmetric ciphers almost always require a key (the "null cipher" is the
only exception), so are unlikely to be used without one. Still,
tracking the key will prevent accidental unkeyed use. algif_skcipher
also had to track the key anyway, so the new flag replaces that and
simplifies the algif_skcipher implementation.

When invoking an asynchronous cipher operation, the invocation of the
callback may be performed before the subsequent operations in the
initial code path are invoked. The callback deletes the cipher request
data structure which implies that after the invocation of the
asynchronous cipher operation, this data structure must not be accessed
any more.
The setting of the return code size with the request data structure must
therefore be moved before the invocation of the asynchronous cipher
operation.

The wait for data is a non-atomic operation that can sleep and therefore
potentially release the socket lock. The release of the socket lock
allows another thread to modify the context data structure. The waiting
operation for new data therefore must be called at the beginning of
recvmsg. This prevents a race condition where checks of the members of
the context data structure are performed by recvmsg while there is a
potential for modification of these values.

The code paths protected by the socket-lock do not use or modify the
socket in a non-atomic fashion. The actions pertaining the socket do not
even need to be handled as an atomic operation. Thus, the socket-lock
can be safely ignored.
This fixes a bug regarding scheduling in atomic as the callback function
may be invoked in interrupt context.
In addition, the sock_hold is moved before the AIO encrypt/decrypt
operation to ensure that the socket is always present. This avoids a
tiny race window where the socket is unprotected and yet used by the AIO
operation.
Finally, the release of resources for a crypto operation is moved into a
common function of af_alg_free_resources.

Split out the following common code from recvmsg:
af_alg_alloc_areq: allocation of the request data structure for the
cipher operation
af_alg_get_rsgl: creation of the RX SGL anchored in the request data
structure
The following changes to the implementation without affecting the
functionality have been applied to synchronize slightly different code
bases in algif_skcipher and algif_aead:
The wakeup in af_alg_wait_for_data is triggered when either more data
is received or the indicator that more data is to be expected is
released. The first is triggered by user space, the second is
triggered by the kernel upon finishing the processing of data
(i.e. the kernel is ready for more).
af_alg_sendmsg uses size_t in min_t calculation for obtaining len.
Return code determination is consistent with algif_skcipher. The
scope of the variable i is reduced to match algif_aead. The type of the
variable i is switched from int to unsigned int to match algif_aead.
af_alg_sendpage does not contain the superfluous err = 0 from
aead_sendpage.
af_alg_async_cb requires to store the number of output bytes in
areq->outlen before the AIO callback is triggered.
The POLLIN / POLLRDNORM is now set when either not more data is given or
the kernel is supplied with data. This is consistent to the wakeup from
sleep when the kernel waits for data.
The request data structure is extended by the field last_rsgl which
points to the last RX SGL list entry. This shall help recvmsg
implementation to chain the RX SGL to other SG(L)s if needed. It is
currently used by algif_aead which chains the tag SGL to the RX SGL
during decryption.

The updated memory management is described in the top part of the code.
As one benefit of the changed memory management, the AIO and synchronous
operation is now implemented in one common function. The AF_ALG
operation uses the async kernel crypto API interface for each cipher
operation. Thus, the only difference between the AIO and sync operation
types visible from user space is:
1. the callback function to be invoked when the asynchronous operation
is completed
2. whether to wait for the completion of the kernel crypto API operation
or not
In addition, the code structure is adjusted to match the structure of
algif_aead for easier code assessment.
The user space interface changed slightly as follows: the old AIO
operation returned zero upon success and < 0 in case of an error to user
space. As all other AF_ALG interfaces (including the sync skcipher
interface) returned the number of processed bytes upon success and < 0
in case of an error, the new skcipher interface (regardless of AIO or
sync) returns the number of processed bytes in case of success.

Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188521. In function
skcipher_recvmsg_async(), variable err takes the return value, and its
value should be negative on failures. Because variable err may be
reassigned and checked before calling kcalloc(), its value may be 0
(indicates no error) even if kcalloc() fails. This patch fixes the bug
by explicitly assigning -ENOMEM to err when kcalloc() returns a NULL
pointer.

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.
