* libprocstat.3: Correct two occurrences of kvm_getprocs to procstat_getprocsMateusz Piotrowski2020-11-261-3/+3

* 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. Thanks to those who have helped along the way: Ryan Moeller, Allan Jude, Zack Welch, and many others. Sponsored by: iXsystems, Inc.

* 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.

* libprocstat: try to fix fallout from r361363Andriy Gapon2020-05-241-0/+4
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the ino_t, dev_t, nlink_t types to 64-bit ints. Modify struct dirent layout to add d_off, increase the size of d_fileno to 64-bits, increase the size of d_namlen to 16-bits, and change the required alignment. Increase struct statfs f_mntfromname[] and f_mntonname[] array length MNAMELEN to 1024. ABI breakage is mitigated by providing compatibility using versioned symbols, ingenious use of the existing padding in structures, and by employing other tricks. Unfortunately, not everything can be fixed, especially outside the base system. For instance, third-party APIs which pass struct stat around are broken in backward and forward incompatible ways. Kinfo sysctl MIBs ABI is changed in backward-compatible way, but there is no general mechanism to handle other sysctl MIBS which return structures where the layout has changed. It was considered that the breakage is either in the management interfaces, where we usually allow ABI slip, or is not important. Struct xvnode changed layout, no compat shims are provided. For struct xtty, dev_t tty device member was reduced to uint32_t. It was decided that keeping ABI compat in this case is more useful than reporting 64-bit dev_t, for the sake of pstat. Update note: strictly follow the instructions in UPDATING. Build and install the new kernel with COMPAT_FREEBSD11 option enabled, then reboot, and only then install new world.

This avoids VMMAP corruption and truncation, even if names change, at the cost of up to PATH_MAX bytes per mapped object. The new sysctl is documented in core.5. - Fix note_procstat_vmmap to self-limit in the second pass.

* Detect badly behaved coredump note helpersConrad Meyer2015-09-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Coredump notes depend on being able to invoke dump routines twice; once in a dry-run mode to get the size of the note, and another to actually emit the note to the corefile. When a note helper emits a different length section the second time around than the length it requested the first time, the kernel produces a corrupt coredump. NT_PROCSTAT_FILES output length, when packing kinfo structs, is tied to the length of filenames corresponding to vnodes in the process' fd table via vn_fullpath. As vnodes may move around during dump, this is racy. So: - Detect badly behaved notes in putnote() and pad underfilled notes. - Add a fail point, debug.fail_point.fill_kinfo_vnode__random_path to exercise the NT_PROCSTAT_FILES corruption. It simply picks random lengths to expand or truncate paths to in fo_fill_kinfo_vnode(). - Add a sysctl, kern.coredump_pack_fileinfo, to allow users to disable kinfo packing for PROCSTAT_FILES notes. This should avoid both FILES note corruption and truncation, even if filenames change, at the cost of about 1 kiB in padding bloat per open fd. Document the new sysctl in core.5. - Fix note_procstat_files to self-limit in the 2nd pass. Since sometimes this will result in a short write, pad up to our advertised size. This addresses note corruption, at the risk of sometimes truncating the last several fd info entries. - Fix NT_PROCSTAT_FILES consumers libutil and libprocstat to grok the zero padding.
