* libprocstat: improve conditional for 32-bit compatBrooks Davis2023-10-262-3/+8
| | | | | | | | | | | | Include support for translating 32-bit auxv vectors on non-64-bit platforms that aren't riscv (which has no 32-bit ABI support and probably never will).

* libprocstat: copy all the 32-bit auxv entriesBrooks Davis2023-10-261-2/+2
| | | | | | | | | | | | | Use source struct size not the destination struct size so we copy all the auxv entries, not just the first half of them. Fix a style issue on an adjacent line.

* libprocstat: make sv_name not staticBrooks Davis2023-10-261-1/+1
| | | | | | | | | | | | | | | Making this variable static makes is_elf32_sysctl() and callers thread unsafe. Use a less absurd length for sv_name. The longest name in the system is "FreeBSD ELF64 V2" which tips the scales at 16+1 bytes. We'll almost certainly have other problems if we exceed 32 characters.

* libprocstat kstack: fix race with thread creationEric van Gyzen2022-03-021-1/+2
| | | | | | | | | | | | | | | | When collecting kernel stacks for a target process, if the process adds a thread between the two calls to sysctl, ignore the additional threads. Previously, procstat would print only a useless error message. Now, it prints a consistent snapshot of the stacks. We know that snapshot is already stale, but it could still be stale even with a more complex fix to reallocate and retry, so such a fix is hardly worth the effort.

* 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.

* Merge OpenZFS support in to HEAD.Matt Macy2020-08-253-20/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid adding duplicates to SRCS/OBJS/SOBJS/POBJSAlex Richardson2020-08-241-2/+0
| | | | | | | | | | | | | | | | | This is a change in preparation for stopping to use lorder.sh (D26044) and instead assume that we have a linker newer than ~1990. Without lorder.sh duplicates end up being passed to the linker when building .so files and this can result in duplicate symbol definition errors. There is one minor change: libcompiler_rt.a will no longer provide gcc_personality_v0 and instead we now only have it in libgcc_eh.a/libgcc_s.so. This matches GCC's behaviour.

| | | | | | | | | | | | | | | | | | | | The revision caused libprocstat to have two undefined symbols: - __start_set_pcpu - __stop_set_pcpu probably because of __GLOBL() used in sys/pcpu.h under _KERNEL. The symbols are not accessed by anything and the linker in base does not complain about them, but some ports are failing to build. Hack around the problem by providing definitions for those symbols. Probably there is a better solution, but I could not think of it yet. Reported by: zeising MFC after: 3 days X-MFC with: r361363 Sponsored by: Panzura Notes: svn path=/head/; revision=361434
* libprocstat: fix ZFS supportAndriy Gapon2020-05-225-65/+139
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | The new structure is copy-on-write. With the assumption that path lookups are significantly more frequent than chdirs and chrooting this is a win. This provides stable root and jail root vnodes without the need to reference them on lookup, which in turn means less work on globally shared structures. Note this also happens to fix a bug where jail vnode was never referenced, meaning subsequent access on lookup could run into use-after-free.
