| | | | | | | | | | | | | | | | | nvd: add hw.nvd.delete_max tunable The NVMe specification does not define a maximum or optimal delete size, so technically max delete size is min(full size of namespace, 2^32 - 1 LBAs). A single delete operation for a multi-TB NVMe namespace though may take much longer to complete than the nvme(4) I/O timeout period. So choose a sensible default here that is still suitably large to minimize the number of overall delete operations. This also fixes possible uint32_t overflow on initial TRIM operation for zpool create operations for NVMe namespaces with >4G LBAs. Approved by: re (glebius) Sponsored by: Intel

The changes in r287442 required some reworking since the 'fo_fill_kinfo' file op does not exist in stable/10. 287442: Detect badly behaved coredump note helpers 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. 287537: Follow-up to r287442: Move sysctl to compiled-once file Avoid duplicate sysctl nodes. 288944: Fix core corruption caused by race in note_procstat_vmmap This fix is spiritually similar to r287442 and was discovered thanks to the KASSERT added in that revision. NT_PROCSTAT_VMMAP output length, when packing kinfo structs, is tied to the length of filenames corresponding to vnodes in the process' vm map via vn_fullpath. As vnodes may move during coredump, this is racy. We do not remove the race, only prevent it from causing coredump corruption. - Add a sysctl, kern.coredump_pack_vmmapinfo, to allow users to disable kinfo packing for PROCSTAT_VMMAP notes. 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. This addresses corruption, at the cost of sometimes producing a truncated result. - Fix PROCSTAT_VMMAP consumers libutil (and libprocstat, via copy-paste) to grok the new zero padding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add devctl(8): a utility for manipulating new-bus devices. Note that this version does not include the 'suspend' and 'resume' commands present in HEAD as those depend on larger changes to the suspend and resume code in the kernel. 278320: Add a new device control utility for new-bus devices called devctl. This allows the user to request administrative changes to individual devices such as attach or detaching drivers or disabling and re-enabling devices. - Add a new /dev/devctl2 character device which uses ioctls for device requests. The ioctls use a common 'struct devreq' which is somewhat similar to 'struct ifreq'. - The ioctls identify the device to operate on via a string. This string can either by the device's name, or it can be a bus-specific address. (For unattached devices, a bus address is the only way to locate a device.) Bus drivers register an eventhandler to claim unrecognized device names that the driver recognizes as a valid address. Two buses currently support addresses: ACPI recognizes any device in the ACPI namespace via its full path starting with "\" and the PCI bus driver recognizes an address specification of 'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector strings supported by pciconf). - To make it easier to cut and paste, change the PnP location string in the PCI bus driver to output a full PCI selector string rather than 'slot=<slot> function=<func>'. - Add a devctl(3) interface in libdevctl which provides a wrapper around the ioctls and is the preferred interface for other userland code. - Add a devctl(8) program which is a simple wrapper around the requests supported by devctl(3). - Add a resource_unset_value() function that can be used to remove a hint from the kernel environment. This is used to clear a hint.<driver>.<unit>.disabled hint when re-enabling a boot-time disabled device. 278336: Unbreak the build (memchr is explicitly required by devctl(9) after r278320) 278830: install the man page... 285621: Fix formatting.

Add a new d_priv_dtor_t typedef that declares the function and can be used as a function prototype. The previous typedef wasn't useful outside of the cdevpriv implementation, so retire it. The name d_priv_dtor_t was chosen to be more consistent with cdev methods since it is commonly used in place of d_close_t even though it is not a direct pointer in struct cdevsw.

| | | | | | | | | | | | | | | | | | | | | | nvme: add hw.nvme.min_cpus_per_ioq tunable Due to FreeBSD system-wide limits on number of MSI-X vectors (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199321), it may be desirable to allocate fewer than the maximum number of vectors for an NVMe device, in order to save vectors for other devices (usually Ethernet) that can take better advantage of them and may be probed after NVMe. This tunable is expressed in terms of minimum number of CPUs per I/O queue instead of max number of queues per controller, to allow for a more even distribution of CPUs per queue. This avoids cases where some number of CPUs have a dedicated queue, but other CPUs need to share queues. Ideally the PR referenced above will eventually be fixed and the mechanism implemented here becomes obsolete anyways. While here, fix a bug in the CPUs per I/O queue calculation to properly account for the admin queue's MSI-X vector.

| | | | | | | | | | | | | | | | | | | | resolver: automatically reload /etc/resolv.conf On each resolver query, use stat(2) to see if the modification time of /etc/resolv.conf has changed. If so, reload the file and reinitialize the resolver library. However, only call stat(2) if at least two seconds have passed since the last call to stat(2), since calling it on every query could kill performance. This new behavior is enabled by default. Add a "reload-period" option to disable it or change the period of the test. Document this behavior and option in resolv.conf(5). Polish the man page just enough to appease igor.
