* Add device location wiring to the pci bus.Warner Losh2017-12-201-0/+28
| | | | | | | | | | | | | | | | | | | | | | | This allows one to specify, for example, that if there's an igb card in bus 12, slot 0, function 0, it should be assigned igb5. If there isn't, or there's one in a different slot, normal numbering rules apply (hinted units are skipped). Adding 'hint.igb.5.at="pci12:0:0"' or 'hint.igb.5.at="pci0:12:0:0"' to /boot/device.hints will accomplish this. The double quotes are important. The kernel only accepts the strings (in shell notation): pci$d:$b:$s:$f and pci$b:$s:$f where $d is the pci domain, $b is the pci bus number, $s is the slot number and $f is the function number. A string compare is done with the current device to avoid another string parser in the kernel. All numbers are unsigned decimal without leading zeros.

| | | | | | | | | | | | | | | | | MD_READONLY flag for the md device automatically instantiated during kernel init for an mdroot filesystem. Note that there is specifically and by design no tunable or sysctl control over this feature. Without this option, you already have control over whether the mdroot fs is writeable using vfs.root.mountfrom.options from loader(8), the root_rw_mount rcvar, and by using "mount -u[rw] /" or equivelent on the fly. This option is being added to provide a way to make the mdroot fs truly immutable before userland code begins running.

* Rework pathconf handling for FIFOs.John Baldwin2017-12-1911-52/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the one hand, FIFOs should respect other variables not supported by the fifofs vnode operation (such as _PC_NAME_MAX, _PC_LINK_MAX, etc.). These values are fs-specific and must come from a fs-specific method. On the other hand, filesystems that support FIFOs are required to support _PC_PIPE_BUF on directory vnodes that can contain FIFOs. Given this latter requirement, once the fs-specific VOP_PATHCONF method supports _PC_PIPE_BUF for directories, it is also suitable for FIFOs permitting a single VOP_PATHCONF method to be used for both FIFOs and non-FIFOs. To that end, retire all of the FIFO-specific pathconf methods from filesystems and change FIFO-specific vnode operation switches to use the existing fs-specific VOP_PATHCONF method. For fifofs, set it's VOP_PATHCONF to VOP_PANIC since it should no longer be used. While here, move _PC_PIPE_BUF handling out of vop_stdpathconf() so that only filesystems supporting FIFOs will report a value. In addition, only report a valid _PC_PIPE_BUF for directories and FIFOs.

Due to the FreeBSD memory model, the operations are syntaxical wrappers around the volatile accesses. The volatile qualifier is used to ensure that the access not optimized out and in turn depends on the volatile semantic as implemented by supported compilers. The motivation for adding the operation is to help people coming from other systems or knowing the C11/C++ standards where atomics have special type and require use of the special access operations.
