2016-04-18ppc: Fix the range check in the LSWI instructionThomas Huth
There are two issues: First, the number of registers that are used has to be calculated with "(nb + 3) / 4" (i.e. round always up, not down). Second, the "start <= ra && (start + nr - 32) > ra" condition for the wrap-around case is wrong: It has to be tested with "||" instead of "&&". Since we can reuse this check later for the LSWX instruction, let's place the fixed code into a helper function, too.

Previously it was only enabled since 2.2.3 since that is when it was enabled properly for ARM. This will allow seccomp support to be enabled for MIPS back to libseccomp 2.2.0.

2016-04-15nbd: Don't kill server on client that doesn't request TLSEric Blake
Upstream NBD documents (as of commit 4feebc95) that servers MAY choose to operate in a conditional mode, where it is up to the client whether to use TLS. For qemu's case, we want to always be in FORCEDTLS mode, because of the risk of man-in-the-middle attacks, and since we never export more than one device; likewise, the qemu client will ALWAYS send NBD_OPT_STARTTLS as its first option. But now that SELECTIVETLS servers exist, it is feasible to encounter a (non-qemu) client that is programmed to talk to such a server, and does not do NBD_OPT_STARTTLS first, but rather wants to probe if it can use a non-encrypted export. The NBD protocol documents that we should let such a client continue trying, on the grounds that maybe the client will get the hint to send NBD_OPT_STARTTLS, rather than immediately dropping the connection. Note that NBD_OPT_EXPORT_NAME is a special case: since it is the only option request that can't have an error return, we have to (continue to) drop the connection on that one; rather, what we are fixing here is that all other replies prior to TLS initiation tell the client NBD_REP_ERR_TLS_REQD, but keep the connection alive.

2016-04-15nbd: fix assert() on qemu-nbd stopPavel Butsykin
From time to time qemu-nbd is crashing on the following assert: assert(state == TERMINATING); nbd_export_closed nbd_export_put main and the state at the moment of the crash is evaluated to TERMINATE. During shutdown process of the client the nbd_client_thread thread sends SIGTERM signal and the main thread calls the nbd_client_closed callback. If the SIGTERM callback will be executed after change the state to TERMINATING, then the state will once again be TERMINATE. To solve the issue, we must change the state to TERMINATE only if the state is RUNNING. In the other case we are shutting down already.

2016-04-15nbd: Don't fail handshake on NBD_OPT_LIST descriptionsEric Blake
The NBD Protocol states that NBD_REP_SERVER may set 'length > sizeof(namelen) + namelen'; in which case the rest of the packet is a UTF-8 description of the export. While we don't know of any NBD servers that send this description yet, we had better consume the data so we don't choke when we start to talk to such a server. Also, a (buggy/malicious) server that replies with length < sizeof(namelen) would cause us to block waiting for bytes that the server is not sending, and one that replies with super-huge lengths could cause us to temporarily allocate up to 4G memory. Sanity check things before blindly reading incorrectly.

The check on the max_table_size field not being larger than required is valid, and in accordance with the VHD spec. However, there have been VHD images encountered in the wild that have an out-of-spec max table size that is technically too large. There is no issue in allowing this larger table size, as we also later verify that the computed size (used for the pagetable) is large enough to fit all sectors. In addition, max_table_entries is bounds checked against SIZE_MAX and INT_MAX. Remove the strict check, so that we can accomodate these sorts of images that are benignly out of spec.

2016-04-15block: Fix blk_aio_write_zeroes()Kevin Wolf
Commit 57d6a428 broke blk_aio_write_zeroes() because in some write functions in the call path don't have an explicit length argument but reuse qiov->size instead. Which is great, except that write_zeroes doesn't have a qiov, which this commit interprets as 0 bytes. Consequently, blk_aio_write_zeroes() didn't effectively do anything. This patch introduces an explicit acb->bytes in BlkAioEmAIOCB and uses that instead of acb->rwco.size. The synchronous version of the function is okay because it does pass a qiov (with the right size and a NULL pointer as its base).

2016-04-14hw/virtio/balloon: Replace TARGET_PAGE_SIZE with BALLOON_PAGE_SIZEThomas Huth
The balloon code currently calls madvise() with TARGET_PAGE_SIZE as length parameter. Since the virtio-balloon protocol is always based on 4k pages, no matter what the host and guest are using as page size, this could cause problems: If TARGET_PAGE_SIZE is bigger than 4k, the madvise call also destroys the 4k areas after the current one - which might be wrong since the guest did not want free that area yet (in case the guest used as smaller MMU page size than the hard-coded TARGET_PAGE_SIZE). So to fix this issue, introduce a proper define called BALLOON_PAGE_SIZE (which is 4096) to use this as the size parameter for the madvise() call instead.

So temporary comment out TPM._CRS.IRQ to 'fix' regression in TPM, with intent to fix it correctly later i.e.: 1. pick unused IRQ as default one for TPM 2. fetch IRQ value from device model so that user could override default one if it conflicts with some other device.

Read absolute and relative axis information, only classify devices as mouse/tablet in case the x axis is present. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2016-04-13virtio-input: fix emulated tablet axis rangesLadi Prosek
The reported maximum was wrong. The X and Y coordinates are 0-based so if size is 8000 maximum must be 7FFF. Signed-off-by: Ladi Prosek <lprosek@redhat.com> Message-id: 1460128893-10244-1-git-send-email-lprosek@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2016-04-13virtio-input: add live migration supportGerd Hoffmann
virtio-input is simple enough that it doesn't need to xfer any state. Still we have to wire up savevm manually, so the generic pci and virtio are saved correctly. Additionally we need to do some post-load processing to figure whenever the guest uses the device or not, so we can give input routing hints to the qemu input layer using qemu_input_handler_{activate,deactivate}.

2016-04-13virtio-input: implement pass-through evdev writesLadi Prosek
The write path for pass-through devices, commonly used for controlling keyboard LEDs via EV_LED, was not implemented. This commit adds the necessary plumbing to connect the status virtio queue to the host evdev file descriptor.

VIRTIO_INPUT_CFG_EV_BITS with subsel of EV_LED was always returning an empty bitmap for pass-through input devices. Signed-off-by: Ladi Prosek <lprosek@redhat.com> Message-id: 1459418028-7473-1-git-send-email-lprosek@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2016-04-13virtio-input: add missing key mappingsLadi Prosek
KEY_PAUSE is flat out missing. KEY_SYSRQ already has a keycode assigned but it's not what I'm seeing on my system. The mapping doesn't appear to have to be unique so both keycodes now map to KEY_SYSRQ which is what the "Keyboard PrintScreen", HID usage ID 0x46, translates to.
