| | | | | | | | | | | Reduce number of opens by REOM RAID during provider taste. Instead opening/closing provider by each of metadata classes, do it only once in core code.

| | | | | | | | | | | | | | | | | | | | | Prevent users from deactivating the last component of a mirror. MFC r259929: Add an ability to stop gmirror and clear its metadata in one command. This fixes the problem, when gmirror starts again just after stop. The problem occurs when gmirror's component has geom label with equal size. E.g. gpt and gptid have the same size as partition, diskid has the same size as entire disk. When gmirror's geom has been destroyed, glabel creates its providers and this initiate retaste. Now "gmirror destroy" command is available. It destroys geom and also erases gmirror's metadata. PR: 184985 Notes: svn path=/stable/9/; revision=260507

| | | | | | | | | | | | | | | | | | | When zero'ing out a buffer, make sure we are using right size. Without this change, in the worst but unlikely case scenario, certain administrative operations, including change of configuration, set or delete key from a GEOM ELI provider, may leave potentially sensitive information in buffer allocated from kernel memory. We believe that it is not possible to actively exploit these issues, nor does it impact the security of normal usage of GEOM ELI providers when these operations are not performed after system boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove stub implementation. MFC r251588 (by marcel): Change the set and unset ctlreqs by making the index argument optional. This allows setting attributes on tables. One simply does not provide an index in that case. Otherwise the entry corresponding the index has the attribute set or unset. Use this change to fix a relatively longstanding bug in our GPT scheme that's the result of rev 198097 (relatively harmless) followed by rev 237057 (damaging). The damaging part being that our GPT scheme always has the active flag set on the PMBR slice. This is in violation with EFI. Existing EFI implementions for both x86 and ia64 reject the GPT. As such, GPT disks created by us aren't usable under EFI because of that. After this change, GPT disks never have the active flag set on the PMBR slice. In order to make the GPT disk bootable under some x86 BIOSes, the reason of rev 198097, one must now set the active attribute on the gpt table. The kernel will apply this to the PMBR slice For (S)ATA: gpart set -a active ada0 To fix an existing GPT disk that has the active flag set in the PMBR, and that does not need the flag, use (again for (S)ATA): gpart unset -a active ada0 The EBR, MBR & PC98 schemes, which also impement at least 1 attribute, now check to make sure the entry passed is valid. They do not have attributes that apply to the table. Notes: svn path=/stable/9/; revision=255017

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some slight differences from the version in FreeBSD/head. __FreeBSD_version has been bumped to 902503 for the availability of the SI_UNMAPPED cdev flag, and the D_UNMAPPED_IO cdevsw flag remains in place. D_UNMAPPED_IO no longer does anything. Drivers that use that flag will just wind up having mapped I/O by default. The impact will only be on performance, not functionality. Change the way that unmapped I/O capability is advertised. The previous method was to set the D_UNMAPPED_IO flag in the cdevsw for the driver. The problem with this is that in many cases (e.g. sa(4)) there may be some instances of the driver that can handle unmapped I/O and some that can't. The isp(4) driver can handle unmapped I/O, but the esp(4) driver currently cannot. The cdevsw is shared among all driver instances. So instead of setting a flag on the cdevsw, set a flag on the cdev. This allows drivers to indicate support for unmapped I/O on a per-instance basis. sys/conf.h: Remove the D_UNMAPPED_IO cdevsw flag and replace it with an SI_UNMAPPED cdev flag. kern_physio.c: Look at the cdev SI_UNMAPPED flag to determine whether or not a particular driver can handle unmapped I/O. geom_dev.c: Set the SI_UNMAPPED flag for all GEOM cdevs. Since GEOM will create a temporary mapping when needed, setting SI_UNMAPPED unconditionally will work. Remove the D_UNMAPPED_IO flag. nvme_ns.c: Set the SI_UNMAPPED flag on cdevs created here if NVME_UNMAPPED_BIO_SUPPORT is enabled. vfs_aio.c: In aio_qphysio(), check the SI_UNMAPPED flag on a cdev instead of the D_UNMAPPED_IO flag on the cdevsw. sys/param.h: Bump __FreeBSD_version to 1000045 for the switch from setting the D_UNMAPPED_IO flag in the cdevsw to setting SI_UNMAPPED in the cdev.

* MFC r226840: AESNI-related commit, from a long time ago:Ollivier Robert2013-08-252-12/+5
| | | | | | | | | | | | | | | | | | | | | | Before this change when GELI detected hardware crypto acceleration it will start only one worker thread. For software crypto it will start by default N worker threads where N is the number of available CPUs. This is not optimal if hardware crypto is AES-NI, which uses CPU for AES calculations. Change that to always start one worker thread for every available CPU. Number of worker threads per GELI provider can be easly reduced with kern.geom.eli.threads sysctl/tunable and even for software crypto it should be reduced when using more providers. While here, when number of threads exceeds number of CPUs avilable don't reduce this number, assume the user knows what he is doing.

SPC-4 specification states that serial number may be property of device, but not a specific logical unit.

SPC-4 states that designators associated with logical unit from the VPD page 83h "Device Identification" should be used for that purpose.
