* mini-os: build fixes for lwip 1.3.2David Vrabel2013-01-301-1/+11
| | | | | | | | | | | | | Various fixes to mini-os needed to build lwip 1.3.2: - Don't build the tests. - Add BSD-style endianness macros to endian.h. - free() is called via a function pointer so it needs to be a real function. Do the same for malloc() and realloc(). Signed-off-by: David Vrabel <david.vrabel@citrix.com> Acked-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Committed-by: Keir Fraser <keir@xen.org>

* minios: add tpmfront, tpm_tis, and tpmback driversMatthew Fioravante2012-11-131-0/+48
| | | | | | | | | | | | | | | | | | | | This patch adds 3 new drivers to mini-os. tpmfront - paravirtualized tpm frontend driver tpmback - paravirtualized tpm backend driver tpm_tis - hardware tpm driver Unfortunately these drivers were derived from GPL licensed linux kernel drivers so they must carry the GPL license. However, since mini-os now supports conditional compilation, hopefully these drivers can be included into the xen tree and conditionally removed from non-gpl projects. By default they are disabled in the makefile.

* nstore: rename public xenstore headersIan Campbell2012-05-142-2/+2
| | | | | | | | | | | | | | | | | | | | | | The xenstore header xs.h is producing conflicts with other software[1]. xs is a too short identifier and does not matche the library. Renaming the headers to xenstore.h and xenstore_lib.h is the easiest way to make them easy recognizable and prevent furthe problems.

* mini-os: make frontends and xenbus optionalDaniel De Graaf2012-02-091-0/+59
| | | | | | | | | | | | | | | | | This adds compile-time logic to disable certain frontends in mini-os: - pcifront is disabled by default, enabled for ioemu - blkfront, netfront, fbfront, kbdfront, consfront are enabled by default - xenbus is required for any frontend, and is enabled by default If all frontends and xenbus are disabled, mini-os will run without needing to communicate with xenstore, making it suitable to run the xenstore daemon. The console frontend is not required for the initial console, only consoles opened via openpt or ptmx.

* mini-os: use BSD sys/queue.h instead of Linux list.hIan Campbell2012-01-312-40/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latter is GPL which makes the whole of mini-os GPL rather than BSD as intended. In tree users are all GPL or GPL-compatible but we should fix this so that mini-os is BSD. Do so by using the same BSD sys/queue.h as we use in libxl. Tested with the builtin mini-os test app and qemu stubdomain, both of which appear to still function as expected. Move tools/libxl/external and the associated sed script to tools/include/xen-external to allow more sensible access from mini-os. Also add s/NULL/0/ in the sed script due to NULL not always being defined in stubdom code when mini-os/wait.h is included. As well as the obvious ABI changes there are a few API updates associated with the change: - struct rw_semaphore.wait_list is unused - remove_waiter needs to take the wait_queue_head The latter requires a qemu update, so there is also a QEMU_TAG update in this changeset. I sprinkled some extra-emacs local variables around the files I edited which didn't have them. I think this should be backported to the stable branches since external users of mini-os may have been mislead into thinking they could safely link mini-os against GPL-incompatible code.

* mini-os: lib/math.c: import FreeBSD 8 functionsSamuel Thibault2011-05-011-44/+65
| | | | | | | | | Import lib/math.c functions (and thus licence) from FreeBSD 8, and re-apply a few of our changes. Whitespaces left aside, this leads to almost no source change except s/int64_t/quad_t/ and s/uint64_t/u_quad_t/. Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
* mini-os: Fix printf.c licenceSamuel Thibault2011-05-011-38/+31

* libxl, minios: stubdom console based save/restoreStefano Stabellini2011-01-211-1/+38
| | | | | | | | | | | | | | | | Add two "special" PV consoles to stubdoms that are going to be used to send and receive the qemu-xen save files on save/restore. Use the second PV console to send the qemu-xen save file and the third PV console to receive the qemu-xen save file on restore. Fix the console shutdown function free_consfront that is called when the qemu save file is closed. Stubdom save/restore is still broken with xend.

* tools: remove fs-front/fs-backTim Deegan2011-01-111-208/+13
| | | | | | | | | | | | | | | | Its access controls are really not OK. In particular, it's not good for libxl, which stores per-VM config blobs in a directory that is exported to all VMs. This will break stub-qemu save/restore, which is the only user of fs-front that I'm aware of, but: - It's currently broken anyway (fs-back isn't run by default and crashes if it is run manually); and - Stefano has a plan to plumb qemu save records through a dedicated console channel instead.

* minios: reverse layering of xc vs minios fd closeKeir Fraser2010-12-031-7/+6
| | | | | | | | | | | | Having minios close() call back into the libxc core close routines is backwards and unexpected. On every other OS the libxc core close routine calls close(). Export minios specific functions from the minios libxc code to implement fd closing for each type of xc file handle and simply call close() in the core close routine.

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-2/+3
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* stubdom: mmap on /dev/mem supportKeir Fraser2009-10-211-1/+11
| | | | | | | | | | This patch adds support for mmap on /dev/mem in a stubdom; it is secure because it only works for memory areas that have been explicitly allowed by the toolstack (xc_domain_iomem_permission).

| | | | | | | | | | | The first function is compiled only in case minios is compiled without newlib, since newlib already provides an implementation for ffs. On the other hand ffsl and ffsll are always compiled because newlib misses those functions. This patch also provides an implementation for __ffsti2 and __ffsdi2 because they are needed by gcc in order to successfully link ffsll.

* stubdom: drop lwip supportKeir Fraser2009-04-231-7/+9
| | | | | | | | | | | | | | | | | | | | Network support is still provided the same way: using the tap interface, created in qemu using netfront. The lwip stack is still available to avoid additional compilation issues. However the stubdom is not going to have its own vif anymore, this means that the only vnc server supported is the one in dom0. You can still enable the vnc server in a stubdom at compile time, if you want so. Probably the most important change caused by this patch to xen users is that you don't have to specify two vif in the stubdom config file anymore, but just one: -vif = [ '', 'ip=10.0.1.1,mac=aa:00:00:12:23:34'] +vif = ['ip=10.0.1.1,mac=aa:00:00:12:23:34'] Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
