60fa8ade1a dde_rump: propagate CC_OLEVEL to buildrump.sh
This effectively enables configuring builds with -O0 for rump sources.
Note, if the build directory is not clean, at least var/libcache/rump*
should be removed before building with changed etc/tools.conf.

ed52d5a211 Introduce 'spec' subdirectories to outline aspects
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:

  repos/base/include/spec
  repos/base/mk/spec
  repos/base/lib/mk/spec
  repos/base/src/core/spec
  ...

Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

2f1db06deb rump_fs/fuse_fs/lx_fs/ram_fs: symlink fixup
Allow symlinks to be passed to the read and write file system utilities.

Disallow writes to symlinks with offsets in file system servers, this is
to ensure that writing the target of a symlink is an atomic operation.

1e3c80ff5b arm: enable cpu cortex_a15 compiler flag
To enable the usage of virtualization extension related instructions
there is the need to enable the '-mcpu=cortex_a15' compiler flag on
those cpus. To not conflict with other compiler flags (Ref #810) we've
to disable the '-march=arm_v7a' flag.

786fe805da base: introduce caching attributes (fix #1184)
On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.

e777165090 dde_rump: block encryption server using cgd(4)
The 'rump_cgd' server provides block level encryption for a block
session by employing the 'cgd(4)' device provided by the rumpkernel.

'rump_cgd' uses a Block_session to get access to an existing block
device and provides another Block_session to its clients. Each block
written or read by the client is transperently encrypted or decrypted
by the server.

For now 'rump_cgd' may only _configure_ a 'cgd' device but is unable
to generate a configuration. The used cipher is hardcoded to
_aes-cbc_ with a keysize of 256 bit. Furthermore the server is able to
serve one client only.

To ease the usage, its interface is modelled after the interface of
'cgdconfig(8)'. As implications thereof the key must have the same
format as used by 'cgdconfig'. That means the key is a base 64 encoded
string in which the first 4 bytes denote the actual length of the key
in bits (these 4 bytes are stored in big endian order).

Preparing a raw (e.g. without partition table) encrypted Ext2 disk
image is done by executing 'tool/rump':

! dd if=/dev/urandom of=/path/to/disk_image
! rump -c /path/to/disk_image # key is printed to stdout
! rump -c -k <key> -F ext2fs /path/to/disk_image

To use this disk image the following config snippet can be used:

! <start name="rump_cgd">
! 	<resource name="RAM" quantum="8M" />
! 	<provides><service name="Block"/></provides>
! 	<config action="configure">
! 		<params>
! 			<method>key</method>}
! 			<key>AAABAJhpB2Y2UvVjkFdlP4m44449Pi3A/uW211mkanSulJo8</key>
! 		</params>
! 	</config>
! 	<route>
! 		<service name="Block"> <child name="ahci"/> </service>
! 		<any-service> <parent/> <any-child/> </any-service>
! 	</route>
! </start>

the Block service provided by rump_cgd may be used by a file system
server in return:

! <start name="rump_fs">
! 	<resource name="RAM" quantum="16M"/>
! 	<provides><service name="File_system"/></provides>
! 	<config fs="ext2fs">
! 		<policy label="" root="/" writeable="yes"/>
! 	</config>
! 	<route>
! 		<service name="Block"> <child name="rump_cgd"/> </service>
! 		<any-service> <parent/> <any-child/> </any-service>
! 	</route>
! </start>

Since 'tool/rump' just utilizes the rumpkernel running on the host
system to do its duty there is a script called 'tool/cgdconf' that
extracts the key from a 'cgdconfig(8)' generated configuration file
and also is able to generade such a file from a given key. Thereby
the interoperabilty between 'rump_cgd' and the general rumpkernel
based tools is secured.

c04ddbf6d8 dde_rump: move memcpy() to rump lib

the definitions from rump_fs to the rump library because it is needed
