* Add some new modes to OpenCrypto. These modes are AES-ICM (can be usedJohn-Mark Gurney2014-12-1211-446/+1607
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for counter mode), and AES-GCM. Both of these modes have been added to the aesni module. Included is a set of tests to validate that the software and aesni module calculate the correct values. These use the NIST KAT test vectors. To run the test, you will need to install a soon to be committed port, nist-kat that will install the vectors. Using a port is necessary as the test vectors are around 25MB. All the man pages were updated. I have added a new man page, crypto.7, which includes a description of how to use each mode. All the new modes and some other AES modes are present. It would be good for someone else to go through and document the other modes. A new ioctl was added to support AEAD modes which AES-GCM is one of them. Without this ioctl, it is not possible to test AEAD modes from userland. Add a timing safe bcmp for use to compare MACs. Previously we were using bcmp which could leak timing info and result in the ability to forge messages. Add a minor optimization to the aesni module so that single segment mbufs don't get copied and instead are updated in place. The aesni module needs to be updated to support blocked IO so segmented mbufs don't have to be copied. We require that the IV be specified for all calls for both GCM and ICM. This is to ensure proper use of these functions.

* Fix various issues with invalid file operations:John Baldwin2014-09-121-54/+5
| | | | | | | | | | | | | | | | | | | | | - Add invfo_rdwr() (for read and write), invfo_ioctl(), invfo_poll(), and invfo_kqfilter() for use by file types that do not support the respective operations. Home-grown versions of invfo_poll() were universally broken (they returned an errno value, invfo_poll() uses poll_no_poll() to return an appropriate event mask). Home-grown ioctl routines also tended to return an incorrect errno (invfo_ioctl returns ENOTTY). - Use the invfo_*() functions instead of local versions for unsupported file operations. - Reorder fileops members to match the order in the structure definition to make it easier to spot missing members. - Add several missing methods to linuxfileops used by the OFED shim layer: fo_write(), fo_truncate(), fo_kqfilter(), and fo_stat(). Most of these used invfo_*(), but a dummy fo_stat() implementation was added. Notes: svn path=/head/; revision=271489

* Fix cryptodev UIO creation.Rafal Jaworowski2009-05-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cryptodev uses UIO structure do get data from userspace and pass it to cryptographic engines. Initially UIO size is equal to size of data passed to engine, but if UIO is prepared for hash calculation an additional small space is created to hold result of operation. While creating space for the result, UIO I/O vector size is correctly extended, but uio_resid field in UIO structure is not modified. As bus_dma code uses uio_resid field to determine size of UIO DMA mapping, resulting mapping hasn't correct size. This leads to a crash if all the following conditions are met: 1. Hardware cryptographic accelerator writes result of hash operation using DMA. 2. Size of input data is less or equal than (n * PAGE_SIZE), 3. Size of input data plus size of hash result is grather than (n * PAGE_SIZE, where n is the same as in point 2. This patch fixes this problem by adding size of the extenstion to uio_resid field in UIO structure.

| | | | | | | | | | | | | | | | | This makes it possible to support ftruncate() on non-vnode file types in the future. - 'struct fileops' grows a 'fo_truncate' method to handle an ftruncate() on a given file descriptor. - ftruncate() moves to kern/sys_generic.c and now just fetches a file object and invokes fo_truncate(). - The vnode-specific portions of ftruncate() move to vn_truncate() in vfs_vnops.c which implements fo_truncate() for vnode file types. - Non-vnode file types return EINVAL in their fo_truncate() method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and flags with an sxlock. This leads to a significant and measurable performance improvement as a result of access to shared locking for frequent lookup operations, reduced general overhead, and reduced overhead in the event of contention. All of these are imported for threaded applications where simultaneous access to a shared file descriptor array occurs frequently. Kris has reported 2x-4x transaction rate improvements on 8-core MySQL benchmarks; smaller improvements can be expected for many workloads as a result of reduced overhead. - Generally eliminate the distinction between "fast" and regular acquisisition of the filedesc lock; the plan is that they will now all be fast. Change all locking instances to either shared or exclusive locks. - Correct a bug (pointed out by kib) in fdfree() where previously msleep() was called without the mutex held; sx_sleep() is now always called with the sxlock held exclusively. - Universally hold the struct file lock over changes to struct file, rather than the filedesc lock or no lock. Always update the f_ops field last. A further memory barrier is required here in the future (discussed with jhb). - Improve locking and reference management in linux_at(), which fails to properly acquire vnode references before using vnode pointers. Annotate improper use of vn_fullpath(), which will be replaced at a future date. In fcntl(), we conservatively acquire an exclusive lock, even though in some cases a shared lock may be sufficient, which should be revisited. The dropping of the filedesc lock in fdgrowtable() is no longer required as the sxlock can be held over the sleep operation; we should consider removing that (pointed out by attilio).
