2012-08-04linux-user: Allocate the right amount of space for non-fixed file mapsRichard Henderson1-11/+19
If we let the kernel handle the implementation of mmap_find_vma, via an anon mmap, we must use the size as indicated by the user and not the size truncated to the filesize. This happens often in ld.so, where we initially mmap the file to the size of the text+data+bss to reserve an area, then mmap+fixed over the top to properly handle data and bss.

2012-08-04Fixes related to processing of qemu's -numa optionChegu Vinod4-25/+27
The -numa option to qemu is used to create [fake] numa nodes and expose them to the guest OS instance. There are a couple of issues with the -numa option: a) Max VCPU's that can be specified for a guest while using the qemu's -numa option is 64. Due to a typecasting issue when the number of VCPUs is > 32 the VCPUs don't show up under the specified [fake] numa nodes. b) KVM currently has support for 160VCPUs per guest. The qemu's -numa option has only support for upto 64VCPUs per guest. This patch addresses these two issues. Below are examples of (a) and (b) a) >32 VCPUs are specified with the -numa option: /usr/local/bin/qemu-system-x86_64 \ -enable-kvm \ 71:01:01 \ -net tap,ifname=tap0,script=no,downscript=no \ -vnc :4 ...

2012-08-03vnc: disable VNC password authentication (security type 2) when in FIPS modePaul Moore6-3/+63
FIPS 140-2 requires disabling certain ciphers, including DES, which is used by VNC to obscure passwords when they are sent over the network. The solution for FIPS users is to disable the use of VNC password auth when the host system is operating in FIPS compliance mode and the user has specified '-enable-fips' on the QEMU command line. This patch causes QEMU to emit a message to stderr when the host system is running in FIPS mode and a VNC password was specified on the commend line. If the system is not running in FIPS mode, or is running in FIPS mode but VNC password authentication was not requested, QEMU operates normally.

It is in any case obsolete since (a) the function arguments it refers to have been replaced with a single MemoryRegionSection* argument and (b) the inability to handle regions whose offset_within_address_space and offset_within_region aren't equally aligned was fixed as part of the rewrite of this code.

2012-08-03exec.c: Use subpages for large unaligned mappingsTyler Hall1-4/+9
Registering a multi-page memory region that is non-page-aligned results in a subpage from the start to the page boundary, some number of full pages, and possibly another subpage from the last page boundary to the end. The full pages will have a value for offset_within_region that is not a multiple of TARGET_PAGE_SIZE. Accesses through softmmu are unable to handle this and will segfault. Handling full pages through subpages is not optimal, but only non-page-aligned mappings take the penalty.

2012-08-03exec.c: Fix off-by-one error in register_subpageTyler Hall1-1/+1
subpage_register() expects "end" to be the last byte in the mapping. Registering a non-page-aligned memory region that extends up to or beyond a page boundary causes subpage_register() to silently fail through the (end >= PAGE_SIZE) check. This bug does not cause noticeable problems for mappings that do not extend to a page boundary, though they do register an extra byte.

2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell17-23/+70
For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.

2012-08-01target-i386: move cpu halted decision into x86_cpu_resetIgor Mammedov6-15/+36
MP initialization protocol differs between cpu families, and for P6 and onward models it is up to CPU to decide if it will be BSP using this protocol, so try to model this. However there is no point in implementing MP initialization protocol in qemu. Thus first CPU is always marked as BSP. This patch: - moves decision to designate BSP from board into cpu, making cpu self-sufficient in this regard. Later it will allow to cleanup hw/pc.c and remove cpu_reset and wrappers from there. - stores flag that CPU is BSP in IA32_APIC_BASE to model behavior described in Inted SDM vol 3a part 1 chapter 8.4.1 - uses MSR_IA32_APICBASE_BSP flag in apic_base for checking if cpu is BSP patch is based on Jan Kiszka's proposal: http://thread.gmane.org/gmane.comp.emulators.qemu/100806 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
