2020-06-18crc-t10dif: clean up some more thingsEric Biggers
- Correctly compare the algorithm name in crc_t10dif_notify(). - Use proper NOTIFY_* status codes instead of 0. - Consistently use CRC_T10DIF_STRING instead of "crct10dif" directly. - Use a proper type for the shash_desc context. - Use crypto_shash_driver_name() instead of open-coding it. - Make crc_t10dif_transform_show() use snprintf() rather than sprintf(). This isn't actually necessary since the buffer has size PAGE_SIZE and CRYPTO_MAX_ALG_NAME < PAGE_SIZE, but it's good practice. - Give the "transform" sysfs file mode 0444 rather than 0644, since it doesn't implement a setter method. - Adjust the module description to not be the same as crct10dif-generic.

2020-06-18crc-t10dif: use fallback in initial stateEric Biggers
Currently the crc-t10dif module starts out with the fallback disabled and crct10dif_tfm == NULL. crc_t10dif_mod_init() tries to allocate crct10dif_tfm, and if it fails it enables the fallback. This is backwards because it means that any call to crc_t10dif() prior to module_init (which could theoretically happen from built-in code) will crash rather than use the fallback as expected. Also, it means that if the initial tfm allocation fails, then the fallback stays permanently enabled even if a crct10dif implementation is loaded later. Change it to use the more logical solution of starting with the fallback enabled, and disabling the fallback when a tfm gets allocated for the first time. This change also ends up simplifying the code. Also take the opportunity to convert the code to use the new static_key API, which is much less confusing than the old and deprecated one. Cc: Martin K.

2020-06-18crc-t10dif: Fix potential crypto notify dead-lockHerbert Xu
The crypto notify call occurs with a read mutex held so you must not do any substantial work directly. In particular, you cannot call crypto_alloc_* as they may trigger further notifications which may dead-lock in the presence of another writer. This patch fixes this by postponing the work into a work queue and taking the same lock in the module init function. While we're at it this patch also ensures that all RCU accesses are marked appropriately (tested with sparse). Finally this also reveals a race condition in module param show function as it may be called prior to the module init function. It's fixed by testing whether crct10dif_tfm is NULL (this is true iff the init function has not completed assuming fallback is false).

A 5.7 kernel hangs during a tcrypt test of padata that waits for an AEAD request to finish. This is only seen on large machines running many concurrent requests. The issue is that padata never serializes the request. The removal of the reorder_objects atomic missed that the memory barrier in padata_do_serial() depends on it.

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.

2020-06-15crypto: algboss - don't wait during notifier callbackEric Biggers
When a crypto template needs to be instantiated, CRYPTO_MSG_ALG_REQUEST is sent to crypto_chain. cryptomgr_schedule_probe() handles this by starting a thread to instantiate the template, then waiting for this thread to complete via crypto_larval::completion. This can deadlock because instantiating the template may require loading modules, and this (apparently depending on userspace) may need to wait for the crc-t10dif module (lib/crc-t10dif.c) to be loaded. But crc-t10dif's module_init function uses crypto_register_notifier() and therefore takes crypto_chain.rwsem for write. That can't proceed until the notifier callback has finished, as it holds this semaphore for read. Fix this by removing the wait on crypto_larval::completion from within cryptomgr_schedule_probe(). It's actually unnecessary because crypto_alg_mod_lookup() calls crypto_larval_wait() itself after sending CRYPTO_MSG_ALG_REQUEST. This only actually became a problem in v4.20 due to commit b76377543b73 ("crc-t10dif: Pick better transform if one becomes available"), but the unnecessary wait was much older.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

The ALE parameters structure is created on stack, so it has to be reset before passing to cpsw_ale_create() to avoid garbage values.

2020-06-13doc: don't use deprecated "---help---" markers in target docsLinus Torvalds
I'm not convinced the script makes useful automaed help lines anyway, but since we're trying to deprecate the use of "---help---" in Kconfig files, let's fix the doc example code too.
