Removed all traces of LN_FLAGS. It was only used to produce a link /usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2, and this link was broken if DESTDIR was set. Added a SYMLINKS macro. This works the same as LINKS, except it creates symlinks and the linked-to pathname may be relative. This is more flexible than LN_FLAGS, since it supports installing symlinks independently of hard links. Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and SYMLINKS. This is equivalent if the target is neither a directory nor a symlink to a directory. PR: 8279

Eliminate the use of commons in the kernel and modules, simplifying the module linking process and eliminating the risks associated with doubly-defined variables. Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)

The old DT_NEEDED tag is still supported by the loader (and will remain supported for a while) - but the kernel side presently doesn't know how to deal with DT_NEEDED.

Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules).

Do not check for existence of ${_dir}/kern/ , because for modules that set .PATH to ${.CURDIR}/[...]/kern , the "exists" expression will fail for the form exists(${.CURDIR}/[...]/kern/). This appears to be happening because make is searching for the argument to "exists" by using .PATH rather than a relative search, because .PATH and the argument match at the beginning. Additionally, make appears to consider a path that starts with ${.CURDIR} as relative, even though it expands to an absolute path. The reason that most people aren't seeing this problem is that the absolute paths of /usr/src/sys and /sys are also searched, so as long as the kernel source can be found in at least one of those places, no problems surface. This problem was inadvertently introduced on 1 December 2000, with the addition of the sysvipc modules.

Add variable INSTALLFLAGS_EDIT used to remove arbitrary INSTALLFLAGS. Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/") this makes the NOFSCHG flag redundant. NOFSCHG will still be honoured by bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }" to emphasize the fact that NOFSCHG is only supported in a limited fashion and for buildworld. The interface and implementation are such that future use of flags such as sappnd can also be easily removed or altered (perhaps to uappnd).

Removed all traces of LN_FLAGS. It was only used to produce a link /usr/sbin/sysctl -> ${DESTDIR}/sbin/sysctl in some versions of 2.2, and this link was broken if DESTDIR was set. Added a SYMLINKS macro. This works the same as LINKS, except it creates symlinks and the linked-to pathname may be relative. This is more flexible than LN_FLAGS, since it supports installing symlinks independently of hard links. Use `ln -f[s] ...' instead of `rm -f ...; ln [-s] ...' for LINKS and SYMLINKS. This is equivalent if the target is neither a directory nor a symlink to a directory. PR: 8279

If the symbolic links @ or machine exist, do not depend on them. This fixes the problem where if src/sys or src/sys/$MACHINE_ARCH/include changed at all, all the modules would be rebuilt. Reviewed by: bde

Use the -c and -h args of vnode_if.sh to generate only the .h file that we use. The .c half is statically compiled into the kernel. It's kinda silly to generate a .h file on the fly that has inlines to call the .c stuff when the .c code is fixed. Also, zap the special treatment for VFS_KLD modules. This treatment applies to lots of things, not just VFS's.

Make it easier to create filesystem LKMs by doing most of the work in the Makefile. Just define VFS_LKM and you're off!

Fixed dependencies of ${PROG} on ${DPSRCS} and `all' on ${_ILINKS}. There were various races for `make -j'. Half-built versions of vnode_if.h were sometimes #included... Removed a null dependency.

Fixed `make depend', which I broke here about a month ago by moving the null default for `depend' from bsd.dep.mk to bsd.obj.mk. bsd.kmod.mk included these files in a bad order, so it picked up the null default.
