2014-10-06Add configure --with-sysconfig-leaf-dir=SUBDIR to set CONFIG_LEAF_DIROlaf Hering
Set CONFIG_LEAF_DIR with configure to give control if needed. The check for the correct value if the option is not specified is tricky. Since other packages (such as grub2) started to populate also /etc/default/ a given system may have both directories. Use "default" only if /etc/sysconfig does not exist. "sysconfig" remains the default. Move the variable from StdGNU.mk to Linux.mk because thats the only place where it is used.

This replaces config/Linux.modules with a configure option. As a result of this change only a single xencomons.in is required, instead of a xencomons.in.in and sed hackery. After this change blktap2 and blktap will be loaded at the same time. This is already done in out-of-tree xencommons scripts, and systemd will load both modules as well.

2014-10-06Use configure --libexecdir=BASEDIR to set LIBEXECOlaf Hering
The current usage of LIBEXEC is bogus. It describes the directory for private xen executables. Other places create their own, similar libexecdir path as $prefix/lib/xen/*. Additional two other variables are used to describe similar paths: PRIVATE_BINDIR and PRIVATE_PREFIX The autoconf documentation refers to libexec as a directory for executables and stuff which is called by other programs, not by the user. Adjust all places that want libexecdir as a target path. LIBEXEC refers now to the base directory. Three convenience variables are used to refer to paths to private binaries, libs and include files. In the systemd files LIBEXEC_BIN is substituted, so this variable has to be present in autoconf. All other variables are expanded in Paths.mk because they are only used in Makefiles. Most users of LIBEXEC are updated to use LIBEXEC_BIN because that is what they want. Users of PRIVATE_BINDIR are updated to use LIBEXEC_BIN because that is what they want. PRIVATE_BINDIR and PRIVATE_PREFIX usage is removed by this patch, in favour of LIBXEC_BIN and LIBEXEC An internal libxl function was removed. A single helper to retrieve LIBEXEC_BIN remains. As suggested by the autoconf documentation, configure appends the package name to LIBEXEC to make sure the provided directory really refers to xen. This makes sure "make uninstall" preserves the real libexecdir.

2014-10-06Substitue configure variables in Paths.mk.inOlaf Hering
This patch lays the groundwork to convert variables used in Makefiles to the common automake style, i.e. PREFIX becomes prefix, MANDIR becomes mandir and so on. The reason is that configure variables such as mandir expand to ${datarootdir}/man, and datarootdir expands to ${prefix}/share. This requires extra expansion in configure.ac before assigning to MANDIR. Special care must be taken when variable substition is done in other files, such as xencommons.in. All @VARIABLES@ used in these files have to be the expanded version, or all other variables must be available at runtime. This patch by itself changes nothing, but upcoming changes will make use of the lowercase variables.

2014-10-06tools: fix make uninstallOlaf Hering
The uninstall target does not know about the paths it removes because the toplevel Makefile does not include the required files. Move the commands to tools/Makefile because all files come from subdirs in tools/ anyway. Drop the removal of $(XEN_RUN_DIR) because it gets created at runtime. Drop the removal of systemd related files because the wildcard matches everything. The proper fix is to remove the files and directories in the Makefiles which install them.

If caller does not care this, it should use current cpu to eliminate the IPI overhead. Batch resource operations in one call are also supported but the max number currently is limited to 2.

2014-10-06x86/paging: make log-dirty operations preemptibleJan Beulich
Both the freeing and the inspection of the bitmap get done in (nested) loops which - besides having a rather high iteration count in general, albeit that would be covered by XSA-77 - have the number of non-trivial iterations they need to perform (indirectly) controllable by both the guest they are for and any domain controlling the guest (including the one running qemu for it). Note that the tying of the continuations to the invoking domain (which previously [wrongly] used the invoking vCPU instead) implies that the tools requesting such operations have to make sure they don't issue multiple similar operations in parallel. Note further that this breaks supervisor-mode kernel assumptions in hypercall_create_continuation() (where regs->eip gets rewound to the current hypercall stub beginning), but otoh hypercall_cancel_continuation() doesn't work in that mode either. Perhaps time to rip out all the remains of that feature? This is part of CVE-2014-5146 / XSA-97.

2014-10-06AMD/guest_iommu: properly disable guest iommu supportAndrew Cooper
AMD Guest IOMMU support was added to allow correct use of PASID and PRI hardware support with an ATS-aware guest driver. However, support cannot possibly function as guest_iommu_set_base() has no callers. This means that its MMIO region's P2M pages are not set to p2m_mmio_dm, preventing any invocation of the MMIO read/write handlers. c/s fd186384 "x86/HVM: extend LAPIC shortcuts around P2M lookups" introduces a path (via hvm_mmio_internal()) where iommu_mmio_handler claims its MMIO range, and causes __hvm_copy() to fail with HVMCOPY_bad_gfn_to_mfn. iommu->mmio_base defaults to 0, with a range of 8 pages, and is unilaterally enabled in any HVM guests when the host IOMMU(s) supports any extended features. Unfortunately, HVMLoader's AP boot trampoline executes an `lmsw` instruction at linear address 0x100c which unconditionally requires emulation. The instruction fetch in turn fails as __hvm_copy() fails with HVMCOPY_bad_gfn_to_mfn. The result is that multi-vcpu HVM guests do not work on newer AMD hardware, if IOMMU support is enabled in the BIOS. Change the default mmio_base address to ~0ULL. This prevents guest_iommu_mmio_range() from actually claiming any physical range whatsoever, which allows the emulation of `lmsw` to succeed.

2014-10-06x86: favor function parameter over global in construct_dom0()Jan Beulich
There's no reason to use the "hardware_domain" variable anywhere here, making the code more cumbersome to read. Signed-off-by: Jan Beulich <jbeulich@suse.com> Reviewed-by: Tim Deegan <tim@xen.org> Reviewed-by: Andrew Cooper <andrew.cooper3@citrix.com>
2014-10-06don't allow Dom0 access to IOMMUs' MMIO pagesJan Beulich
Just like for LAPIC, IO-APIC, MSI, and HT we shouldn't be granting Dom0 access to these. This implicitly results in these pages also getting marked reserved in the machine memory map Dom0 uses to determine the ranges where PCI devices can have their MMIO ranges placed.

2014-10-06x86: restore reserving of IO-APIC pages in XENMEM_machine_memory_map outputJan Beulich
Commit d1222afda4 ("x86: allow Dom0 read-only access to IO-APICs") had an unintended side effect: By no longer adding IO-APIC pages to Dom0's iomem_caps these also no longer get reported as reserved in the machine memory map presented to it (which got added there intentionally by commit b8a456caed ["x86: improve reporting through XENMEM_machine_memory_map"] because many BIOSes fail to add these).

2014-10-06x86/MSI: fix MSI-X case of freeing IRQJan Beulich
Commit d1b6d0a024 ("x86: enable multi-vector MSI") went a little too far with moving things around in msi_free_irqs() in order to streamline the code: We shouldn't drop the MSI-X control page reference before calling destroy_irq(), as the latter will call us back via desc->handler->shutdown() (effectively invoking to msi_set_mask_bit()).

2014-10-03amd/seattle: Initial revision of AMD Seattle supportSuravee Suthikulpanit
This patch add initial (minimal) platform support for AMD Seattle, which mainly just define the matching ID, and specify system_off, and system_reset mechanism. Initially, the firmware only support a subset of PSCI-0.2 functions, system-off and system-reset. The mechanism for bring up auxiliary processors is still using spin-table.

2014-10-03xen/arm: Fix crash if last memory section is bigger than 1gbFrediano Ziglio
On arm32 the xenheap has a maximum size of 1GB. On systems with more than 8GB (so 1/8 total RAM is greater than 1GB) there is no point in searching for a region with 1/8 of the total RAM when only 1GB will be used. Therefore limit the maximum size to 1GB before searching.
