* libxl: HVM firmware passthrough supportRoss Philipson2013-02-154-17/+129
| | | | | | | | | | | | | | | | | | | | | | This patch introduces support for two new parameters in libxl: smbios_firmware=<path_to_smbios_structures_file> acpi_firmware=<path_to_acpi_tables_file> The changes are primarily in the domain building code where the firmware files are read and passed to libxc for loading into the new guest. After the domain building call to libxc, the addresses for the loaded blobs are returned and written to xenstore. LIBXL_HAVE_FIRMWARE_PASSTHROUGH is defined in libxl.h to allow users to determine if the feature is present. This patch also updates the xl.cfg man page with descriptions of the two new parameters for firmware passthrough.

* tools/ocaml: oxenstored: Be more paranoid about ring readingIan Jackson2013-02-071-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | oxenstored makes use of the OCaml Xenbus bindings, in which the function xs_ring_read in tools/ocaml/libs/xb/xs_ring_stubs.c is used to read from the shared memory Xenstore ring. This function does not correctly handle all possible (prod, cons) states when MASK_XENSTORE_IDX(prod) > MASK_XENSTORE_IDX(cons). The root cause is the use of the unmasked values of prod and cons to calculate to_read. If prod is set to an out-of-range value, the ring peer can cause to_read to be too large or even negative. This allows the ring peer to force oxenstored to read and write out of range for the buffers leading to a crash or possibly to privilege escalation. Correct this by masking the values of cons and prod at the start, so we only deal with masked values. This makes the logic simpler, as semantically inappropriate values of the upper bits of the ring pointers are simply ignored. The same vulnerability does not exist in the ring writer because the only use made of the unmasked value is the check which prevents the prod pointer overtaking the cons pointer. A ring peer which defeats this check will suffer only lost data. However, additionally, precautions need to be taken to ensure that req_cons and req_prod are only read once in each function. Without the use of volatile or some asm construct, the compiler can "prove" that req_cons and req_prod do not change unexpectedly and is permitted to "amplify" the read of (say) req_cons into two reads at different times, giving two different values for use as cons, and then use the two sources of cons interchangeably. (The use of xen_mb() does not forbid this.) Therefore do the reads of req_cons and req_prod through a volatile pointer in both xs_ring_read and xs_ring_write. This is currently believed to be a theoretical vulnerability as we are not aware of any compilers which amplify reads in this way. This is a security issue, part of XSA-38 / CVE-2013-0215.

* tools+stubdom: install under /usr/local by default.Ian Campbell2013-01-242-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the defacto (or FHS mandated?) standard location for software built from source, in order to avoid clashing with packaged software which is installed under /usr/bin etc. I think there is benefit in having Xen's install behave more like the majority of other OSS software out there. The major downside here is in the transition from 4.2 to 4.3 where people who have built from source will innevitably discover breakage because 4.3 no longer overwrites stuff in /usr like it used to so they pickup old stale bits from /usr instead of new stuff from /usr/local. Packages will use ./configure --prefix=/usr or whatever helper macro their package manager gives them. I have confirmed that doing this results in the same list of installed files as before this patch was applied. The hypervisor remains in /boot/ and there is no intention to move it.

* libxl: fix stale timeout event callback raceIan Jackson2013-01-242-77/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because there is not necessarily any lock held at the point the application (eg, libvirt) calls libxl_osevent_occurred_timeout, in a multithreaded program those calls may be arbitrarily delayed in relation to other activities within the program. Specifically this means when ->timeout_deregister returns, libxl does not know whether it can safely dispose of the for_libxl value or whether it needs to retain it in case of an in-progress call to _occurred_timeout. The interface could be fixed by requiring the application to make a new call into libxl to say that the deregistration was complete. However that new call would have to be threaded through the application's event loop; this is complicated and some application authors are likely not to implement it properly. Furthermore the easiest way to implement this facility in most event loops is to queue up a time event for "now". Shortcut all of this by having libxl always call timeout_modify setting abs={0,0} (ie, ASAP) instead of timeout_deregister. This will cause the application to call _occurred_timeout. When processing this calldown we see that we were no longer actually interested and simply throw it away. Additionally, there is a race between _occurred_timeout and ->timeout_modify. If libxl ever adjusts the deadline for a timeout the application may already be in the process of calling _occurred, in which case the situation with for_app's lifetime becomes very complicated. Therefore abolish libxl__ev_time_modify_{abs,rel} (which have no callers) and promise to the application only ever to call ->timeout_modify with abs=={0,0}. The application still needs to cope with ->timeout_modify racing with its internal function which calls _occurred_timeout. Document this. This is a forwards-compatible change for applications using the libxl API, and will hopefully eliminate these races in callback-supplying applications (such as libvirt) without the need for corresponding changes to the application. (It is possible that this might expose bugs in applications, though, as previously libxl would never call libxl_osevent_hooks->timeout_modify and now it never calls ->timeout_deregister). For clarity, fold the body of time_register_finite into its one remaining call site. This makes the semantics of ev->infinite slightly clearer.

* libxl: fix stale fd event callback raceIan Jackson2013-01-242-29/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because there is not necessarily any lock held at the point the application (eg, libvirt) calls libxl_osevent_occurred_timeout and ..._fd, in a multithreaded program those calls may be arbitrarily delayed in relation to other activities within the program. libxl therefore needs to be prepared to receive very old event callbacks. Arrange for this to be the case for fd callbacks. This requires a new layer of indirection through a "hook nexus" struct which can outlive the libxl__ev_foo. Allocation and deallocation of these nexi is mostly handled in the OSEVENT macros which wrap up the application's callbacks. Document the problem and the solution in a comment in libxl_event.c just before the definition of struct libxl__osevent_hook_nexus. There is still a race relating to libxl__osevent_occurred_timeout; this will be addressed in the following patch.

* xenconsoled: use grant references instead of map_foreign_rangeDaniel De Graaf2013-01-173-10/+42
| | | | | | | | | | | | | | | Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the domain containing xenconsoled.

| | | | | | | | Although this passed my smoke-tests at commit time, I'm now seeing screen corruption on 32-bit WinXP guests. Reverting for now. :( Signed-off-by: Tim Deegan <tim@xen.org> Committed-by: Tim Deegan <tim@xen.org>
* tools: Update to SeaBIOS 1.7.1Ian Campbell2013-01-171-2/+19
| | | | | | | | | | | | | | Only lightly tested with a Linux HVM guest PXE boot. Accept the defaults for the config options. Many of them are not relevant to Xen but this matches what others (at least the Debian SeaBIOS packages and the binary shipped by Qemu) are doing. The Debian Xen packages are built against Debian's SeaBIOS package so there is value in being similar.

* libxl: don't continue to create the domain if the device model is not spawnedJulien Grall2013-01-171-2/+0
| | | | | | | | | | | When the device model can't be spawned, rc variable is cleared in device_model_spawn_outcome (libxl_dm.c). In this case libxl will continue to create the domain and let it between life and death.

* Fix pygrub handling non-default entryMiroslav Rezanina2013-01-171-1/+1
| | | | | | | | | If we pass 0 as pygrub --entry argument (i.e. we want to boot first item), default value is used instead. This is dueto wrong check for range of allowed values of index - 0 is index of first item.

* Switch from select() to poll() in xenconsoled's IO loopWei Liu2013-01-171-72/+140
| | | | | | | | | | | | | | | | | | | In Linux select() typically supports up to 1024 file descriptors. This can be a problem when user tries to boot up many guests. Switching to poll() has minimum impact on existing code and has better scalibility. pollfd array is dynamically allocated / reallocated. If the array fails to expand, we just ignore the incoming fd. Updated: reset *_pollfd after use. This fixes regression 14869. Also remove unused slave_pollfd in strcut domain.

* x86/mm: Provide support for multiple frame buffers in HVM guests.Robert Phillips2013-01-171-6/+14
| | | | | | | | | | | | | | | | | | | | | | Support is provided for both shadow and hardware assisted paging (HAP) modes. This code bookkeeps the set of video frame buffers (vram), detects when the guest has modified any of those buffers and, upon request, returns a bitmap of the modified pages. This lets other software components re-paint the portions of the monitor (or monitors) that have changed. Each monitor has a frame buffer of some size at some position in guest physical memory. The set of frame buffers being tracked can change over time as monitors are plugged and unplugged. Signed-off-by: Robert Phillips <robert.phillips@citrix.com> Acked-by: Tim Deegan <tim@xen.org> Removed a stray #include and a few hard tabs.
