* Add stubdomain support. See stubdom/README for usage details.Keir Fraser2008-02-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in arch_limits.h so as to permit getting them from there without pulling all the internal Mini-OS defines. - Setup a xen-elf cross-compilation environment in stubdom/cross-root - Add a POSIX layer on top of Mini-OS by linking against the newlib C library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c - Cross-compile zlib and libpci too. - Add an xs.h-compatible layer on top of Mini-OS' xenbus. - Cross-compile libxc with an additional xc_minios.c and a few things disabled. - Cross-compile ioemu with an additional block-vbd, but without sound, tpm and other details. A few hacks are needed: - Align ide and scsi buffers at least on sector size to permit direct transmission to the block backend. While we are at it, just page-align it to possibly save a segment. Also, limit the scsi buffer size because of limitations of the block paravirtualization protocol. - Allocate big tables dynamically rather that letting them go to bss: when Mini-OS gets installed in memory, bss is not lazily allocated, and doing so during Mini-OS is unnecessarily trick while we can simply use malloc. - Had to change the Mini-OS compilation somehow, so as to export Mini-OS compilation flags to the Makefiles of libxc and ioemu.

* build: Make PREFIX work by fixing LIBDIRKeir Fraser2008-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | In the current tree, setting PREFIX does not work very well. This is because of confusion about the meaning of LIBDIR. In some places it is the pathname tail of directories containing libraries (lib, lib64 or lib/amd64). But in other places it is a destination pathname (implicitly, including any PREFIX). This can result in PREFIX or /usr being added the wrong number of times. This patch splits LIBDIR into two variables, LIBLEAFDIR and LIBDIR. LIBDIR is the directory into which Xen libraries and other similar code is to be placed, and includes any PREFIX. LIBLEAFDIR is just the library tail and can be appended to various different prefixes; for example, to construct the X11 library directory for -L. Neither variable contains the value of DESTDIR, which is of course used only to redirect the results of `make install' when desired. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* tools: disable lomount and miniterm by defaultKeir Fraser2008-01-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lomount is a tool which reads and parses a partition table in a disk image block device and then uses mount -o ...offset=... to mount it. This is not an ideal approach. For example, if the intended filesystem has corrupted metadata the kernel's filesystem driver may start to write outside of the intended region. This might even be exploitable in some perverse circumstances. Nowadays people wanting to do this should use kpartx, which uses devmapper to create appropriate range mappings. So lomount should be disabled. miniterm may well be useful but it is a clone-and-hack of an upstream project and is currently built but not installed by default, partly because it doesn't make sense to install on the dom0 which it might be trying to debug. It is probably useful to retain these two programs in the source tree but IMO they should no longer be built by default. The attached patch does these things: * CONFIG_LOMOUNT and CONFIG_MINITERM in Config.mk can enable and disable these programs * They are disabled by default * If CONFIG_MINITERM=y it is still built but not installed. make -C tools/misc/miniterm install will install it.

* Revert 16560:822d4ec5cfb1.Keir Fraser2007-12-081-3/+0
| | | | | | | | | | | | | Preference seems to be to update library versions only when the ABI changes. Only libxenctrl/libxenguest have their version number changed to 3.2.0, as a reminder that they change on pretty much every major release. libfsimage/libxenstore/libblktap have not changed substantially recently, hence the ABI has not changed, and version number stays the same as in Xen 3.1 (and before).

* tools: Rationalise library soname versions.Keir Fraser2007-12-071-0/+3
| | | | | | | | | | | | | | | | * Arrange for the sonames of libxenstore, libxc, libfsimage and libblktap to be set from a single place in Config.mk. * Bumps the soname major version number to 3.2 in preparation for 3.2 rc1 after which we do not expect to have ABI changes. I have not done anything about libaio and libflask. The former is imported from elsewhere and if we're lucky will have sane versioning upstream. libflask has a very small interface and I'm hoping that the XSM authors have been keeping some ABI discipline.

* pv-qemu: Remove standalone xenfb codeKeir Fraser2007-10-251-1/+0
| | | | | | | | | | | This patch removes all trace of the standalone paravirt framebuffer daemon. With this there is no longer any requirement for LibVNCServer.

| | | | | | | | | | | | | | | - gcc-3.2 cannot handle some multi-line assertions in the Xen sources. Noone noticed. - gcc-3.3 has problems with alignment constraints inside typedefs. gcc 3.4.0 is now three years old so I hope that everyone has an up-to-date compiler, or can obtain a more up-to-date package for their distribution.

* build: Make sure that DESTDIR is setkaf24@firebug.cl.cam.ac.uk2006-04-101-0/+1
| | | | | | | | | | | | | | | | In the case where XEN_PYTHON_NATIVE_INSTALL is in effect, if DESTDIR is not set then the install will go into a relative directory rather than under the default prefix (usually /usr). An alternate solution would be to update the fragments that do the python install to use $(DESTDIR)/ instead of $(DESTDIR). This is not an incredible burden as there are only two such fragments in the tree. However, it seems prone to error as new makefiles are created in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | time (instead of at compile time). Allows a single xen.gz binary to run under different security policy types, which simplifies distributions considerably. To this end, we replace the current single compile switch in Config.mk with the following two: 1. ACM_SECURITY (y/n) if "n", then the ACM is not compiled and no security policies can be configured at boot time. If "y", then the ACM is compiled and can be configured into any of the available policy types (null, chwall, ste, chwall_ste) by specifying a valid boot policy .bin file in the grub boot configuration. 2. ACM_DEFAULT_SECURITY_POLICY (null / chwall / ste / chwall_ste) specifies the policy into which Xen defaults in the case that security is enabled but no boot policy file is specified, or the specified policy file is invalid (wrong version, magic, corrupted, ...) While the type of the enabled policy (null, ste, ...) is decided once during boot for the whole boot cycle, the policy instantiation can be changed during operation as usual with the security tools.
