* libprocstat: Drop zfs_defs.c hack, including its _KERNEL defineJessica Clarke2025-06-166-192/+38
| | | | | | | | | | | Now that we have a _WANT_ZNODE we can use that instead of defining _KERNEL, and we're able to move the code back into zfs.c using a real znode_t pointer. Whilst here, tidy the includes. Reviewed by: imp, kib, markj Differential Revision: https://reviews.freebsd.org/D50721
* libprocstat: Drop all _KERNEL defines outside of zfs_defs.cJessica Clarke2025-06-165-20/+6
| | | | | | | | | | Defining _KERNEL is a historical hack that can often break due to the environment not actually being that of a kernel build. Now that we have other targeted macros we can define instead that don't have far-reaching implications like _KERNEL we can drop this.

* protosw: this is a kernel only header, put back #ifdef _KERNELGleb Smirnoff2025-02-031-0/+1
| | | | | | | | | | The uncommented #ifdef _KERNEL originates from 1997 by wollman@ (see 57bf258e3dc9e) with no clear original reason. Since these old times two abusers of the header leak were created - libprocstat(3) and netstat(1). These two already have a lot of _WANT_FOO hacks, so satisfy them with _WANT_PROTOSW. While here, cleanup and sort forward declaraions.

* Prepare some build fixes in advance of more _FORTIFY_SOURCEKyle Evans2024-07-132-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | ZFS' libspl needs to be made aware that we have strlcat(3) and strlcpy(3) to avoid some more complicated declaration duplication, so go ahead and define these HAVE_ macros now. libprocstat has to define `_KERNEL` and include kernel headers in order to get what it wants, but this results in sys/cdefs.h being included too late and we pick up the build breaking version of the __RENAME definition. Just explicitly include sys/cdefs.h earlier rather than disabling _FORTIFY_SOURCE. The zfs/ subdir only builds an object that holds some structures and sizes, so just disable _FORTIFY_SOURCE there entirely rather than trying to move #define _KERNEL into the file.. While we're here, make sure that we disable _FORTIFY_SOURCE in the bootloader because we don't have the symbol renaming support today to do it as cleanly as we'd like. ssp/ssp.h needs to be pulled into the libsa environment so that other bits can understand that ssp is disabled in the consistent __SSP_FORTIFY_LEVEL way that we try to do.

* Remove the cloned file descriptors for /dev/crypto.John Baldwin2020-11-252-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Crypto file descriptors were added in the original OCF import as a way to provide per-open data (specifically the list of symmetric sessions). However, this gives a bit of a confusing API where one has to open /dev/crypto and then invoke an ioctl to obtain a second file descriptor. This also does not match the API used with /dev/crypto on other BSDs or with Linux's /dev/crypto driver. Character devices have gained support for per-open data via cdevpriv since OCF was imported, so use cdevpriv to simplify the userland API by permitting ioctls directly on /dev/crypto descriptors. To provide backwards compatibility, CRIOGET now opens another /dev/crypto descriptor via kern_openat() rather than dup'ing the existing file descriptor. This preserves prior semantics in case CRIOGET is invoked multiple times on a single file descriptor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The primary benefit is maintaining a completely shared code base with the community allowing FreeBSD to receive new features sooner and with less effort. I would advise against doing 'zpool upgrade' or creating indispensable pools using new features until this change has had a month+ to soak. Work on merging FreeBSD support in to what was at the time "ZFS on Linux" began in August 2018. I first publicly proposed transitioning FreeBSD to (new) OpenZFS on December 18th, 2018. FreeBSD support in OpenZFS was finally completed in December 2019. A CFT for downstreaming OpenZFS support in to FreeBSD was first issued on July 8th. All issues that were reported have been addressed or, for a couple of less critical matters there are pull requests in progress with OpenZFS. iXsystems has tested and dogfooded extensively internally. The TrueNAS 12 release is based on OpenZFS with some additional features that have not yet made it upstream. Improvements include: project quotas, encrypted datasets, allocation classes, vectorized raidz, vectorized checksums, various command line improvements, zstd compression.

| | | | | | | | | | | | | | | | | | | | | | | First of all, znode_phys_t hasn't been used for storing file attributes for a long time now. Modern ZFS versions use a System Attribute table with a flexible layout. But more importantly all the required information is available in znode_t itself. It's not easy to include zfs_znode.h in userland without breaking code because the most interesting parts of the header are kernel-only. And hardcoding field offsets is too fragile. So, I created a new compilation unit that includes zfs_znode.h using some mild kludges to get it and its dependencies to compile in userland. The compilation unit exports interesting field offsets and does not have any other code.
