* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-1/+1
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
* Pass BIO_SPEEDUP through all the geom layersWarner Losh2020-01-171-0/+4
| | | | | | | | | | | | | | | While some geom layers pass unknown commands down, not all do. For the ones that don't, pass BIO_SPEEDUP down to the providers that constittue the geom, as applicable. No changes to vinum or virstor because I was unsure how to add this support, and I'm also unsure how to test these. gvinum doesn't implement BIO_FLUSH either, so it may just be poorly maintained. gvirstor is for testing and not supportig BIO_SPEEDUP is fine.

* Annotate geom modules with MODULE_VERSIONKyle Evans2018-04-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | GEOM ELI may double ask the password during boot. Once at loader time, and once at init time. This happens due a module loading bug. By default GEOM ELI caches the password in the kernel, but without the MODULE_VERSION annotation, the kernel loads over the kernel module, even if the GEOM ELI was compiled into the kernel. In this case, the newly loaded module purges/invalidates/overwrites the GEOM ELI's password cache, which causes the double asking. MFC Note: There's a pc98 component to the original submission that is omitted here due to pc98 removal in head. This part will need to be revived upon MFC.

* sys/geom: adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-272-0/+4
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326270

* Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky2014-06-271-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

The logical disks will appear as /dev/lvm/<vol group>-<logical vol>, for instance /dev/lvm/vg0-home. G_LINUX_LVM currently supports linear stripes with segments on multiple physical disks. The metadata is read only, logical volumes can not be allocated or resized. Reviewed by: Ivan Voras Previously known as geom_lvm(4), rename requested by des, phk.
