- FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file

2001-05-23T09:42:29Z

systems were repo-copied from sys/miscfs to sys/fs. - Renamed the following file systems and their modules: fdesc -> fdescfs, portal -> portalfs, union -> unionfs. - Renamed corresponding kernel options: FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS. - Install header files for the above file systems. - Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland Makefiles.

Introduce a global lock for the vm subsystem (vm_mtx).

2001-05-19T01:28:09Z

vm_mtx does not recurse and is required for most low level vm operations. faults can not be taken without holding Giant. Memory subsystems can now call the base page allocators safely. Almost all atomic ops were removed as they are covered under the vm mutex. Alpha and ia64 now need to catch up to i386's trap handlers. FFS and NFS have been tested, other filesystems will need minor changes (grabbing the vm lock when twiddling page properties). Reviewed (partially) by: jake, jhb

Undo part of the tangle of having sys/lock.h and sys/mutex.h included in

other "system" header files. Also help the deprecation of lockmgr.h by making it a sub-include of sys/lock.h and removing sys/lockmgr.h form kernel .c files. Sort sys/*.h includes where possible in affected files. OK'ed by: bde (with reservations)

useracc() the prequel:

Merge the contents (less some trivial bordering the silly comments) of and into . This puts the #defines for the vm_inherit_t and vm_prot_t types next to their typedefs. This paves the road for the commit to follow shortly: change useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE} as argument.

This is a rather large commit that encompasses the new swapper,

changes to the VM system to support the new swapper, VM bug fixes, several VM optimizations, and some additional revamping of the VM code. The specific bug fixes will be documented with additional forced commits. This commit is somewhat rough in regards to code cleanup issues. Reviewed by: "John S. Dyson" , "David Greenman"

Examine all occurrences of sprintf(), strcat(), and str[n]cpy()

for possible buffer overflow problems. Replaced most sprintf()'s with snprintf(); for others cases, added terminating NUL bytes where appropriate, replaced constants like "16" with sizeof(), etc. These changes include several bug fixes, but most changes are for maintainability's sake. Any instance where it wasn't "immediately obvious" that a buffer overflow could not occur was made safer. Reviewed by: Bruce Evans Reviewed by: Matthew Dillon Reviewed by: Mike Spengler
