* crypto: algif_skcipher - EBUSY on aio should be an errorHerbert Xu2020-08-211-1/+1
| | | | | | | | | | 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 complete. Fixes: dad419970637 ("crypto: algif_skcipher - Do not set...") Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * crypto: algif_aead - fix uninitialized ctx->initOndrej Mosnacek2020-08-131-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* crypto: af_alg - fix use-after-free in af_alg_accept() due to bh_lock_sock()Herbert Xu2020-06-181-6/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLLLinus Torvalds2018-06-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * crypto: skcipher - prevent using skciphers without setting keyEric Biggers2018-01-121-46/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | crypto: af_alg - wait for data at beginning of recvmsgStephan Mueller2017-12-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | crypto: af_alg - remove locking in async callbackStephan Mueller2017-11-241-11/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* crypto: algif_skcipher - overhaul memory managementStephan Mueller2017-07-281-282/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

It does so by using the new skcipher interface which unlike the previous ablkcipher does not need to create extra geniv objects which is what was used to trigger the WARN_ON" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: algif_skcipher - Use new skcipher interface

* / net: rename SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATAEric Dumazet2015-12-011-3/+3
|/ | | | | | | | | | | | | | | | | | This patch is a cleanup to make following patch easier to review. Goal is to move SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA from (struct socket)->flags to a (struct socket_wq)->flags to benefit from RCU protection in sock_wake_async() To ease backports, we rename both constants. Two new helpers, sk_set_bit(int nr, struct sock *sk) and sk_clear_bit(int net, struct sock *sk) are added so that following patch can change their implementation.
