ATR size exceeding the limit is diagnosed, but then we merrily use it anyway, overrunning card->atr[]. The message is read from a character device. Obvious security implications unless the other end of the character device is trusted. Spotted by Coverity. CVE-2011-4111.

2011-11-28configure: avoid screening of --{en, dis}able-usb-redir optionsMax Filippov
--*dir) option pattern precede --{en,dis}able-usb-redir) patterns in the option analysis switch, making the latter options have no effect. There were some --*dir that are supported by Autoconf and not by QEMU configure. The aim was to let QEMU packagers use the rpm (or similar) macro that overrides directories for their distribution. Replace --*dir with exact option names. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-11-28cutils: Make strtosz & friends leave follow set to callersMarkus Armbruster
strtosz() & friends require the size to be at the end of the string, or be followed by whitespace or ','. I find this surprising, because the name suggests it works like strtol(). The check simplifies callers that accept exactly that follow set slightly. No such callers exist. The check is redundant for callers that accept a smaller follow set, and thus need to check themselves anyway. Right now, this is the case for all but one caller. All of them neglected to check, or checked incorrectly, but the previous few commits fixed them up. Finally, the check is problematic for callers that accept a larger follow set. This is the case in monitor_parse_command(). Fortunately, the problems there are relatively harmless. monitor_parse_command() uses strtosz() for argument type 'o'. When the last argument is of type 'o', a trailing ',' is diagnosed differently than other trailing junk: (qemu) migrate_set_speed 1x invalid size (qemu) migrate_set_speed 1, migrate_set_speed: extraneous characters at the end of line A related inconsistency exists with non-last arguments. No such command exists, but let's use memsave to explore the inconsistency. The monitor permits, but does not require whitespace between arguments. For instance, "memsave (1-1)1024foo" is parsed as command memsave with three arguments 0, 1024 and "foo". Yes, this is daft, but at least it's consistently daft. If I change memsave's second argument from 'i' to 'o', then "memsave (1-1)1foo" is rejected, because the size is followed by an 'f'. But "memsave (1-1)1," is still accepted, and duly saves to file ",". We don't have any users of strtosz that profit from the check. In the users we have, it appears to encourage sloppy error checking, or gets in the way. Drop the bothersome check.

2011-11-28qemu-img: Tighten parsing of size argumentsMarkus Armbruster
strtosz_suffix() fails unless the size is followed by 0, whitespace or ','. Useless here, because we need to fail for any junk following the size, even if it starts with whitespace or ','. Check manually. Things like "qemu-img create xxx 1024," and "qemu-img convert -S '1024 junk'" are now caught.

2011-11-28x86/cpuid: Tighten parsing of tsc_freq=FREQMarkus Armbruster
cpu_x86_find_by_name() uses strtosz_suffix_unit(), but screws up the error checking. It detects some failures, but not all. Undetected failures result in a zero tsc_khz value (error value -1 divided by 1000), which means "no tsc_freq set". To reproduce, try "-cpu qemu64,tsc_freq=9999999T". strtosz_suffix_unit() fails, because the value overflows int64_t, Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-11-28vl: Tighten parsing of -m argumentMarkus Armbruster
strtosz_suffix() fails unless the size is followed by 0, whitespace or ','. Useless here, because we need to fail for any junk following the size, even if it starts with whitespace or ','.

2011-11-28vl: Tighten parsing of -numa's parameter memMarkus Armbruster
strtosz_suffix() fails unless the size is followed by 0, whitespace or ','. Useless here, because we need to fail for any junk following the size, even if it starts with whitespace or ','. Check manually. Things like -smp 4 -numa "node,mem=1024,cpus=0-1" -numa "node,mem=1024 cpus=2-3" are now caught. Before, the second -numa's argument was silently interpreted as just "node,mem=1024".

2011-11-28cutils: Drop broken support for zero strtosz default_suffixMarkus Armbruster
Commit 9f9b17a4's strtosz() defaults a missing suffix to 'M', except it rejects fractions then (switch case 0). When commit d8427002 introduced strtosz_suffix(), that changed: fractions are no longer rejected, because we go to switch case 'M' on missing suffix now. Not mentioned in commit message, probably unintentional. Not worth changing back now. Because case 0 is still around, you can get the old behavior by passing a zero default_suffix to strtosz_suffix() or strtosz_suffix_unit(). Undocumented and not used. Drop. Commit d8427002 also neglected to update the function comment. Fix it up. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-11-28usb-redir: Don't try to write to the chardev after a close eventHans de Goede
Since we handle close async in a bh, do_write and thus write can get called after receiving a close event. This patch adds a check to the usb-redir write callback to not call qemu_chr_fe_write on a closed backend.

2011-11-28usb-redir: Device disconnect + re-connect robustness fixesHans de Goede
These fixes mainly target the other side sending some (error status) packets after a disconnect packet. In some cases these would get queued up and then reported to the controller when a new device gets connected. * Fully reset device state on disconnect * Don't allow a connect message when already connected * Ignore iso and interrupt status messages when disconnected Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-11-28usb-redir: Call qemu_chr_fe_open/closeHans de Goede

2011-11-28spice-qemu-char: Generate chardev open/close eventsHans de Goede
Define a state callback and make that generate chardev open/close events when called by the spice-server. Notes: 1) For all but the newest spice-server versions (which have a fix for this) the code ignores these events for a spicevmc with a subtype of vdagent, this subtype specific knowledge is undesirable, but unavoidable for now, see: http://lists.freedesktop.org/archives/spice-devel/2011-July/004837.html 2) This code deliberately sends the events immediately rather then from a bh. This is done this way because: a) There is no need to do it from a bh; and b) Doing it from a bh actually causes issues because the spice-server may send data immediately after the open and when the open runs from a bh, then qemu_chr_be_can_write will return 0 for the first write which the spice-server does not expect, when this happens the spice-server will never retry the write causing communication to stall.

2011-11-289pfs: improve portability to older systemsPaolo Bonzini
Small requirements on "new" features have percolated to virtio-9p-local.c. In particular, the utimensat wrapper actually only supports dirfd = AT_FDCWD and flags = AT_SYMLINK_NOFOLLOW in the fallback code. Remove the arguments so that virtio-9p-local.c will not use AT_* constants. At the same time, fail local_ioc_getversion if the ioctl is not supported by the host.

2011-11-23usb-host: add usb_host_do_reset function.Gerd Hoffmann
Add a special function to reset the host usb device. It tracks the time needed by the USBDEVFS_RESET ioctl and prints a warning in case it needs too long. Usually it should be finished in 200 - 300 miliseconds. Warning threshold is one second. Intention is to help troubleshooting by indicating that the usb device stopped responding even to a reset request and is possibly broken. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-11-23rtl8139: Fix invalid IO access alignmentJulian Pidancet
This patch makes iPXE work with the rtl8139 emulation. The rtl8139 driver in iPXE issues a 16bit access on the ChipCmd register (offset 0x37) to check the status of the rx buffer. The offset of the ioport access was getting fixed up to 0x36 in qemu, causing the value read in iPXE to be invalid. This fixes an issue with iPXE reporting timeouts during TFTP transfers. Reposting this here because it is trivial enough and the original post on qemu-devel didn't attract much attention. Also, the inw() which was causing the issue has been replaced with an inb() in upstream iPXE: https://git.ipxe.org/ipxe.git/commit/91dd64ad25baa27954a7518e73df4fca8a2d0c93 Signed-off-by: Julian Pidancet <julian.pidancet@gmail.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
