2013-08-14mips_malta: do not raise exceptions when accessing invalid memoryAurelien Jarno5-0/+10
Since commit c658b94f6e8c206c59d02aa6fbac285b86b53d2c, MIPS raises exceptions when accessing invalid memory. This is not the correct behaviour for MIPS Malta Core LV, as the GT-64120A system controller just ignore undecoded access. This feature is used by the Linux kernel to probe for some devices. Emulate the correct behaviour in QEMU by adding an empty slot covering the entire memory space decoded by the GT-64120A.

2013-08-13qemu-char: fix infinite recursion connecting to monitor ptyJames Hogan1-1/+1
Since commit bd5c51e (qemu-char: don't issue CHR_EVENT_OPEN in a BH), an infinite recursion occurs when putting the monitor on a pty (-monitor pty) and connecting a terminal to the slave port. This is because of the qemu_chr_be_event(s, CHR_EVENT_OPENED) added to qemu_chr_be_generic_open(). This event is captured by monitor_event() which prints a welcome message to the character device. The flush of that welcome message retriggers another open event in pty_chr_state() because it checks s->connected, but only sets it to 1 after calling qemu_chr_be_generic_open(). I've fixed this by setting s->connected = 1 before the call to qemu_chr_be_generic_open() instead of after, so that the recursive pty_chr_state() doesn't call it again. An example snippet of repeating backtrace: ... #107486 0x007aec58 in monitor_flush (mon=0xf418b0) at qemu/monitor.c:288 #107487 0x007aee7c in monitor_puts (mon=0xf418b0, str=0x1176d07 "") at qemu/monitor.c:322 #107488 0x007aef20 in monitor_vprintf (mon=0xf418b0, fmt=0x8d4820 "QEMU %s monitor - type 'help' for more information\n", ap=0x7f432be0) at qemu/monitor.c:339 #107489 0x007aefac in monitor_printf (mon=0xf418b0, fmt=0x8d4820 "QEMU %s monitor - type 'help' for more information\n") at qemu/monitor.c:347 #107490 0x007ba4bc in monitor_event (opaque=0xf418b0, event=2) at qemu/monitor.c:4699 #107491 0x00684c28 in qemu_chr_be_event (s=0xf37788, event=2) at qemu/qemu-char.c:108 #107492 0x00684c70 in qemu_chr_be_generic_open (s=0xf37788) at qemu/qemu-char.c:113 #107493 0x006880a4 in pty_chr_state (chr=0xf37788, connected=1) at qemu/qemu-char.c:1145 #107494 0x00687fa4 in pty_chr_update_read_handler (chr=0xf37788) at qemu/qemu-char.c:1121 #107495 0x00687c9c in pty_chr_write (chr=0xf37788, buf=0x70b3c008 <Address 0x70b3c008 out of bounds>, len=538720) at qemu/qemu-char.c:1063 #107496 0x00684cc4 in qemu_chr_fe_write (s=0xf37788, buf=0x70b3c008 <Address 0x70b3c008 out of bounds>, len=538720) at qemu/qemu-char.c:118 ...

2013-08-12rdma: IPv6 over Ethernet (RoCE) is broken in linux - workaroundMichael R. Hines1-20/+169
We've gotten reports from multiple testers (including Frank Yangjie and myself) that RDMA IPv6 support over RocE (Ethernet) is broken in linux. A patch to Linux is still in review: http://comments.gmane.org/gmane.linux.drivers.rdma/16448 If the user is listening on '[::]', then we will not have a opened a device yet and have no way of verifying if the device is RoCE or not. In this case, the source VM will throw an error for ALL types of connections (both IPv4 and IPv6) if the destination machine does not have a regular infiniband network available for use. The only way to gaurantee that an error is thrown for broken kernels is for the management software to choose a *specific* interface at bind time and validate what time of hardware it is. Unfortunately, this puts the user in a fix: If the source VM connects with an IPv4 address without knowing that the destination has bound to '[::]' the migration will unconditionally fail unless the management software is not explicitly listening on the the IPv4 address while using a RoCE-based device. If the source VM connects with an IPv6 address, then we're OK because we can throw an error on the source (and similarly on the destination). But in mixed environments, this will be broken for a while until it is fixed inside linux. We do provide a *tiny* bit of help in mixed environments, though in this patch: We can list all of the devices in the system and check to see if all the devices are RoCE or Infiniband. If we detect that we have a *pure* RoCE environment, then we can safely thrown an error even if the management sofware has specified '[::]' as the bind address. However, if there is are multiple hetergeneous devices, then we cannot make this assumption and the user just has to be sure they know what they are doing. Signed-off-by: Michael R.

2013-08-12qemu-option: Guard against qemu_opts_set_defaults() misuseMarkus Armbruster1-0/+9
Commit 6d4cd40 fixed qemu_opts_set_defaults() for an existing corner case, but broke it for another one that can't be reached in current code. Quote from its commit message: I believe [opts_parse()] attempts to do the following: If options don't yet exist, create new options Else, if defaults, modify the existing options Else, if list->merge_lists, modify the existing options Else, fail The only caller that passes true for defaults is qemu_opts_set_defaults(). The commit message then claims: A straightforward call of qemu_opts_create() does exactly that. Wrong. When !list->merge_lists, and the option string doesn't contain id=, and options without ID exist, then we don't actually modify the existing options, we create new ones. Not reachable, because we never pass lists with !list->merge_lists to qemu_opts_set_defaults(). Guard against possible (if unlikely) future misuse with assert().

Now that this code path is not triggered anymore during the tests, revert commit b332d24a8e1290954029814d09156b06ede358e2. Booting a MIPS target without kernel nor bios doesn't really make sense. At the same time replace fprintf(stderr, ...) by error_report(). Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

tcg/mips/tcg-target.h defines various operations conditionally depending upon the isa revision, however these operations are included in mips_op_defs[] unconditionally resulting in the following runtime errors if CONFIG_DEBUG_TCG is defined: Invalid op definition for movcond_i32 Invalid op definition for rotl_i32 Invalid op definition for rotr_i32 Invalid op definition for deposit_i32 Invalid op definition for bswap16_i32 Invalid op definition for bswap32_i32 tcg/tcg.c:1196: tcg fatal error Fix with ifdefs like the i386 backend does for movcond_i32.

2013-08-08dump: rebase from host-private RAMBlock offsets to guest-physical addressesLaszlo Ersek7-57/+69
RAMBlock.offset --> GuestPhysBlock.target_start RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end RAMBlock.length --> GuestPhysBlock.target_end - GuestPhysBlock.target_start "GuestPhysBlock.host_addr" is only used when writing the dump contents. This patch enables "crash" to work with the vmcore by rebasing the vmcore from the left side of the following diagram to the right side: host-private offset relative to ram_addr RAMBlock guest-visible paddrs 0 +-------------------+.....+-------------------+ 0 | ^ | | ^ | | 640 KB | | 640 KB | | v | | v | 0x0000a0000 +-------------------+.....+-------------------+ 0x0000a0000 | ^ | |XXXXXXXXXXXXXXXXXXX| | 384 KB | |XXXXXXXXXXXXXXXXXXX| | v | |XXXXXXXXXXXXXXXXXXX| 0x000100000 +-------------------+.....+-------------------+ 0x000100000 | ^ | | ^ | | 3583 MB | | 3583 MB | | v | | v | 0x0e0000000 +-------------------+.....+-------------------+ 0x0e0000000 | ^ |. |XXXXXXXXXXXXXXXXXXX| | above_4g_mem_size | . |XXXX PCI hole XXXXX| | v | . |XXXX XXXXX| ram_size +-------------------+ . |XXXX 512 MB XXXXX| . .|XXXXXXXXXXXXXXXXXXX| . +-------------------+ 0x100000000 . | ^ | . | above_4g_mem_size | .| v | +-------------------+ ram_size + 512 MB Related RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=981582 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2013-08-08dump: populate guest_phys_blocksLaszlo Ersek3-1/+86
While the machine is paused, in guest_phys_blocks_append() we register a one-shot MemoryListener, solely for the initial collection of the valid guest-physical memory ranges that happens at listener registration time. For each range that is reported to guest_phys_blocks_region_add(), we attempt to merge the range with the preceding one. Ranges can only be joined if they are contiguous in both guest-physical address space, and contiguous in host virtual address space. The "maximal" ranges that remain in the end constitute the guest-physical memory map that the dump will be based on.

2013-08-08dump: introduce GuestPhysBlockListLaszlo Ersek3-12/+58
The vmcore must use physical addresses that are visible to the guest, not addresses that point into linear RAMBlocks. As first step, introduce the list type into which we'll collect the physical mappings in effect at the time of the dump.

2013-08-08dump: clamp guest-provided mapping lengths to ramblock sizesLaszlo Ersek1-25/+40
Even a trusted & clean-state guest can map more memory than what it was given. Since the vmcore contains RAMBlocks, mapping sizes should be clamped to RAMBlock sizes. Otherwise such oversized mappings can exceed the entire file size, and ELF parsers might refuse even the valid portion of the PT_LOAD entry.

2013-08-07fw_cfg: the I/O port variant expects little-endianPaolo Bonzini1-1/+1
The I/O port variant of fw_cfg is used by sparc64, which is a big-endian machine. Firmware swaps bytes before sending them to fw_cfg, so we need to unswap them in the device. This is only used on sparc64 and on (little-endian) x86, so it does not affect any other target. 32-bit Sparc and PPC all use memory-mapped fw_cfg.
