* serial: 8250: Don't delay after transmitter is ready.David Daney2010-10-22

* vcs: invoke the vt update callback when /dev/vcs* is written toNicolas Pitre2010-10-22
| | | | | | | | | | | | A notifier chain is called whenever the vt code modifies a terminal content, except for one case which is when the modification comes through writes to /dev/vcs* devices. Let's add the missing notifier invocation at the end of vcs_write() for that case too.

* vcs: add poll/fasync supportNicolas Pitre2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | The /dev/vcs* devices are used, amongst other things, by accessibility applications such as BRLTTY to display the screen content onto refreshable braille displays. Currently this is performed by constantly reading from /dev/vcsa0 whether or not the screen content has changed. Given the default braille refresh rate of 25 times per second, this easily qualifies as the biggest source of wake-up events preventing laptops from entering deeper power saving states. To avoid this periodic polling, let's add support for select()/poll() and SIGIO with the /dev/vcs* devices. The implemented semantic is to report data availability whenever the corresponding vt has seen some update after the last read() operation. The application still has to lseek() back as usual in order to read() the new data. Not to create unwanted overhead, the needed data structure is allocated and the vt notification callback is registered only when the poll or fasync method is invoked for the first time per file instance.

* tty: Add a new file /proc/tty/consolesDr. Werner Fink2010-10-22
| | | | | | | | | | | | | Add a new file /proc/tty/consoles to be able to determine the registered system console lines. If the reading process holds /dev/console open at the regular standard input stream the active device will be marked by an asterisk. Show possible operations and also decode the used flags of the listed console lines.

* Char: mxser, call pci_disable_device from probe/removeJiri Slaby2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | Vasiliy found that pci_disable_device is not called on fail paths in mxser_probe. Actually, it is called from nowhere in the driver. There are three changes needed: 1) don't use pseudo-generic mxser_release_res. Let's use it only from ISA paths from now on. All the pci stuff is moved to probe and remove PCI-related functions. 2) reorder fail-paths in the probe function so that it makes sense and we can call them from the sequential code naturally (the further we are the earlier label we go to). 3) add pci_disable_device both to mxser_probe and mxser_remove. There is a nit of adding CONFIG_PCI ifdef to mxser_remove. it is because this driver supports ISA-only compilations and it would choke up on the newly added calls now.

* serial-core: restore termios settings when resume console portsJason Wang2010-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 4547be7 rewrites suspend and resume functions. According to this rewrite, when a serial port is a printk console device and can suspend(without set no_console_suspend flag), it will definitely call set_termios function during its resume, but parameter termios isn't initialized, this will pass an unpredictable config to the serial port. If this serial port is not a userspace opened tty device , a suspend and resume action will make this serial port unusable. I.E. ttyS0 is a printk console device, ttyS1 or keyboard+display is userspace tty device, a suspend/resume action will make ttyS0 unusable. If a serial port is both a printk console device and an opened tty device, this issue can be overcome because it will call set_termios again with the correct parameter in the uart_change_speed function. Refer to the deleted content of commit 4547be7, revert parts relate to restore settings into parameter termios. It is safe because if a serial port is a printk console only device, the only meaningful field in termios is c_cflag and its old config is saved in uport->cons->cflag, if this port is also an opened tty device, it will clear uport->cons->cflag in the uart_open and the old config is saved in tty->termios.

* serial-core: skip call set_termios/console_start when no_console_suspendJason Wang2010-10-22
| | | | | | | | | | | | | | | | | | The commit 4547be7 rewrites suspend and resume functions, this introduces a problem on the OMAP3EVM platoform. when the kernel boots with no_console_suspend and we suspend the kernel, then resume it, the serial console will be not usable. This problem should be common for all platforms. The cause for this problem is that when enter suspend, if we choose no_console_suspend, the console_stop will be skiped. But in resume function, the console port will be set to uninitialized state by calling set_termios function and the console_start is called without checking whether the no_console_suspend is set, Now fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.

| * | | KVM: Fix fs/gs reload oops with invalid ldtAvi Kivity2010-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kvm reloads the host's fs and gs blindly, however the underlying segment descriptors may be invalid due to the user modifying the ldt after loading them. Fix by using the safe accessors (loadsegment() and load_gs_index()) instead of home grown unsafe versions. This is CVE-2010-3698. KVM-Stable-Tag.
