* dtrace: Add the 'oformat' libdtrace optionDomagoj Stolfa2024-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This option can be used to specify a format to use in DTrace output. The following formats are supported: - json - xml - html - none (default DTrace output) This is implemented using libxo and integrated into libdtrace. Client code only works with the following API: - dtrace_oformat_setup(dtrace_hdl_t *) -- to be called when output is starting. - dtrace_oformat_teardown(dtrace_hdl_t *) -- to be called when output is finished - dtrace_oformat(dtrace_hdl_t *) -- check if oformat is enabled. - dtrace_set_outfp(FILE *) -- sets the output file for oformat. - Ensure that oformat is correctly checked in the drop handler and record processing callbacks. This commit also adds tests which check if the generated output is valid (JSON, XML) and extends the dtrace(1) describing the structured output.

* dtrace: do not overload libproc flagsEric van Gyzen2023-08-011-2/+0
| | | | | | | | | | | | | | | | | dtrace stored its PR_RLC and PR_KLC flags in the proc_handle's flags, where they collided with PATTACH_FORCE and PATTACH_RDONLY, respectively. Thus, Psetflags(PR_KLC) effectively also set the PATTACH_RDONLY flag. Since the flags are private to dtrace (at least on FreeBSD), store them in dtrace's own dt_proc structure instead. On FreeBSD, either PR_RLC or PR_KLC was always set, so remove code that would handle the case where neither was set.

* tcp: embed inpcb into tcpcbGleb Smirnoff2022-12-071-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the TCP protocol inpcb storage specify allocation size that would provide space to most of the data a TCP connection needs, embedding into struct tcpcb several structures, that previously were allocated separately. The most import one is the inpcb itself. With embedding we can provide strong guarantee that with a valid TCP inpcb the tcpcb is always valid and vice versa. Also we reduce number of allocs/frees per connection. The embedded inpcb is placed in the beginning of the struct tcpcb, since in_pcballoc() requires that. However, later we may want to move it around for cache line efficiency, and this can be done with a little effort. The new intotcpcb() macro is ready for such move. The congestion algorithm data, the TCP timers and osd(9) data are also embedded into tcpcb, and temprorary struct tcpcb_mem goes away. There was no extra allocation here, but we went through extra pointer every time we accessed this data. One interesting side effect is that now TCP data is allocated from SMR-protected zone. Potentially this allows the TCP stacks or other TCP related modules to utilize that for their own synchronization. Large part of the change was done with sed script: s/tp->ccv->/tp->t_ccv./g s/tp->ccv/\&tp->t_ccv/g s/tp->cc_algo/tp->t_cc/g s/tp->t_timers->tt_/tp->tt_/g s/CCV\(ccv, osd\)/\&CCV(ccv, t_osd)/g Dependency side effect is that code that needs to know struct tcpcb should also know struct inpcb, that added several <netinet/in_pcb.h>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Create new EINTEGRITY error with message "Integrity check failed".Kirk McKusick2019-01-171-1/+4
| | | | | | | | | | | | | | | | | | | | | | An integrity check such as a check-hash or a cross-correlation failed. The integrity error falls between EINVAL that identifies errors in parameters to a system call and EIO that identifies errors with the underlying storage media. EINTEGRITY is typically raised by intermediate kernel layers such as a filesystem or an in-kernel GEOM subsystem when they detect inconsistencies. Uses include allowing the mount(8) command to return a different exit value to automate the running of fsck(8) during a system boot. These changes make no use of the new error, they just add it. Later commits will be made for the use of the new error number and it will be added to additional manual pages as appropriate.
