* Add kpreempt_disable/enable around CPU_SEQID usesMorgan Jones2017-06-191-2/+5
| | | | | | | | | | | In zfs/dmu_object and icp/core/kcf_sched, the CPU_SEQID macro should be surrounded by `kpreempt_disable` and `kpreempt_enable` calls to avoid a Linux kernel BUG warning. These code paths use the cpuid to minimize lock contention and is is safe to reschedule the process to a different processor at any time.

* Fix ICP memleak introduced in #4760Tom Caputi2016-10-121-0/+13
| | | | | | | | | | | | | The ICP requires destructors to for each crypto module that is added. These do not necessarily exist in Illumos because they assume that these modules can never be unloaded from the kernel. Some of this cleanup code was missed when #4760 was merged, resulting in leaks. This patch simply fixes that. Reviewed-by: Tony Hutter <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Tom Caputi <[email protected]> Issue #4760 Closes #5265
* Porting over some ICP code that was missed in #4760Tom Caputi2016-10-101-16/+118
| | | | | | | | | | | | | When #4760 was merged tests were added to ensure that the new checksums were working properly. However, some of the functionality for sha2 functions were not ported over, resulting in some Coverity defects and code that would be unstable when needed in the future. This patch simply ports over the missing code and fixes the defects in the process.

* Unify license of icp module with the rest of zfsNikolay Borisov2016-07-291-1/+1
| | | | | | | | | | | | | | | | The newly added icp module uses a hardcoded value of CDDL for the license, however in local development one might want to change that to something else in order to facilitate compiling against lock debugging enabled kernel. All modules of the zfs use the ZFS_META_LICNSE string which is replaced with the value held in the META file. One can modify the value in the META file once and then rerun the configure to have all modules' licenses changed. Change the icp module license string to be ZFS_META_LICENSE so that it falls under the same paradigm.

* Illumos Crypto Port module added to enable native encryption in zfsTom Caputi2016-07-2066-0/+34499
A port of the Illumos Crypto Framework to a Linux kernel module (found in module/icp). This is needed to do the actual encryption work. We cannot use the Linux kernel's built in crypto api because it is only exported to GPL-licensed modules. Having the ICP also means the crypto code can run on any of the other kernels under OpenZFS. I ended up porting over most of the internals of the framework, which means that porting over other API calls (if we need them) should be fairly easy. Specifically, I have ported over the API functions related to encryption, digests, macs, and crypto templates. The ICP is able to use assembly-accelerated encryption on amd64 machines and AES-NI instructions on Intel chips that support it. There are place-holder directories for similar assembly optimizations for other architectures (although they have not been written).
