* zfsd: Improve spare selectionAlexander Motin2026-06-251-34/+155
| | | | | | | | | | | | | | | Port OpenZFS PRs #18597 and #18578 from zed to zfsd. When activating a spare, sort candidates before trying them: 1. Distributed dRAID spare matching the failed vdev's group (fastest rebuild via sequential resilver) 2. Regular spares 3. Non-matching distributed spares (kernel will reject anyway) 4. Within each tier: prefer rotational match, then smallest sufficient size Also try all healthy spares in order rather than stopping at the first one, and use sequential rebuild for distributed spares.
* Remove -fms-extensions throughout the treeBjoern A. Zeeb2026-04-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a discussion about using -fms-extensions jhb pointed out that we have them enabled in the kernel for gcc by default (even multiple times in one part). I had missed all that and clang still failed on my use case (needing another option). The original cause for enabling them for our tree back then was that we needed to support C11 anonymous struct/unions. Our in-tree gcc 4.2.1, despite later patches, needed the -fms-extensions to support these even though this was not the expected use case for that option ( cc4a90c445aa0 enabled it globally for the kernel). clang at that time (or at least when it became default for 10.0) already was fine (with C11). Any later gcc (4.6.0 onwards) did not need that option anymore, even when compiled for -std=iso9899:1990 (which does not support anonymous structs/unions) unless one would add -pedantic (see gcc git 4bdd0a60b27a). This is also the reason why userland cddl sources now compile with the option removed despite CSTD=c99. The only driver which needed the option recently was ccp, but that was fixed in 8d3f41dbcb2a by jhb. So cleanup all uses cases of -fms-extensions for the moment as they are no longer needed given all compilers currently supported seem to be fine without them and gcc-4.2.1 was removed from the tree in stable/13 in 2020 (a9854bc3812b).

* libdtrace: Permit taking the address of an identifier without type infoMark Johnston2025-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Symbols defined using assembler directives lack type info, but in this case one ought to be able to cast a pointer to the symbol and dereference the pointer to get a value. Without this change, D disallows this trick since it requires all identifiers to have a type. Relax the rules slightly and allow an identifier to have type "void" if we know we're just taking its address. As a result, the following dtrace invocation works: dtrace -n 'tick-1s {printf("%d", *(int *)&`ticks);}' In particular, since commit b2b974f7ef4c ("clock: Simplify subr_ticks and rename"), "ticks" does not have any type info associated with it, so its value couldn't be printed. This trick provides a workaround and is probably generally useful. Add a regression test which exercises this functionality.

* zfsd: Use vdev prop values for fault/degrade thresholdsAlan Somers2024-03-053-43/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | ZED uses vdev props for setting disk fault/degrade thresholds, this patch enables zfsd to use the same vdev props for these same tasks. OpenZFS on Linux is using vdev props for ZED disk fault/degrade thresholds. Originally the thresholds supported were for io and checksum events and recently this was updated to process slow io events as well, see https://github.com/openzfs/zfs/commit/cbe882298e4ddc3917dfaf239eca475fe06d62d4 This patch enables us to use the same vdev props in zfsd as ZED uses. After this patch is merged both OSs will use the same vdev props to set retirement thresholds. It's probably important to note that the threshold defaults are different between OS. I've kept the existing defaults inside zfsd and DID NOT match them to what ZED does.

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.
