Pull MIPS updates from Ralf Baechle: - More work on DT support for various platforms - Various fixes that were to late to make it straight into 3.9 - Improved platform support, in particular the Netlogic XLR and BCM63xx, and the SEAD3 and Malta eval boards. - Support for several Ralink SOC families. - Complete support for the microMIPS ASE which basically reencodes the existing MIPS32/MIPS64 ISA to use non-constant size instructions. - Some fallout from LTO work which remove old cruft and will generally make the MIPS kernel easier to maintain and resistant to compiler optimization, even in absence of LTO. - KVM support. While MIPS has announced hardware virtualization extensions this KVM extension uses trap and emulate mode for virtualization of MIPS32. More KVM work to add support for VZ hardware virtualizaiton extensions and MIPS64 will probably already be merged for 3.11. Most of this has been sitting in -next for a long time. All defconfigs have been build or run time tested except three for which fixes are being sent by other maintainers.

2013-05-01tty: fix up atime/mtime mess, take threeLinus Torvalds2-2/+5
We first tried to avoid updating atime/mtime entirely (commit b0de59b5733d: "TTY: do not update atime/mtime on read/write"), and then limited it to only update it occasionally (commit 37b7f3c76595: "TTY: fix atime/mtime regression"), but it turns out that this was both insufficient and overkill. It was insufficient because we let people attach to the shared ptmx node to see activity without even reading atime/mtime, and it was overkill because the "only once a minute" means that you can't really tell an idle person from an active one with 'w'. So this tries to fix the problem properly. It marks the shared ptmx node as un-notifiable, and it lowers the "only once a minute" to a few seconds instead - still long enough that you can't time individual keystrokes, but short enough that you can tell whether somebody is active or not.

2013-04-30audit: do not needlessly take a lock in tty_audit_exitEric Paris1-3/+0
We were doing spin_lock_irq and spin_unlock_irq. This is STOOPID. If we were in interupt context we were already screwed and called panic() in do_exit(). So the irq stuff is useless. Also, these values can only be changed by receiving a netlink message from current. Since we are in do_exit() clearly we aren't in the syscall sending the netlink message to change these values. Thus, just read them and go with it. Signed-off-by: Eric Paris <eparis@redhat.com>
2013-04-30audit: do not needlessly take a spinlock in copy_signalEric Paris1-4/+0
current->signal->audit_* can only change from a netlink message from current. Obviously in this case we cannot be handling a netlink message from current. So there is no change these can change under us. No need to take a lock to read them. Signed-off-by: Eric Paris <eparis@redhat.com>
2013-04-30audit: add an option to control logging of passwords with pam_tty_auditRichard Guy Briggs1-0/+9
Most commands are entered one line at a time and processed as complete lines in non-canonical mode. Commands that interactively require a password, enter canonical mode to do this while shutting off echo. This pair of features (icanon and !echo) can be used to avoid logging passwords by audit while still logging the rest of the command. Adding a member (log_passwd) to the struct audit_tty_status passed in by pam_tty_audit allows control of canonical mode without echo per task.

2013-04-30audit: use spin_lock_irqsave/restore in audit tty codeEric Paris1-13/+19
Some of the callers of the audit tty function use spin_lock_irqsave/restore. We were using the forced always enable version, which seems really bad. Since I don't know every one of these code paths well enough, it makes sense to just switch everything to the safe version. Maybe it's a little overzealous, but it's a lot better than an unlucky deadlock when we return to a caller with irq enabled and they expect it to be disabled.

In commit b0de59b5733d ("TTY: do not update atime/mtime on read/write") we removed timestamps from tty inodes to fix a security issue and waited if something breaks. Well, 'w', the utility to find out logged users and their inactivity time broke. It shows that users are inactive since the time they logged in.

2013-04-15serial_core.c: add put_device() after device_find_child()Federico Vaga1-0/+4
The serial core uses device_find_child() but does not drop the reference to the retrieved child after using it. This patch add the missing put_device(). What I have done to test this issue. I used a machine with an AMBA PL011 serial driver. I tested the patch on next-20120408 because the last branch [next-20120415] does not boot on this board. For test purpose, I added some pr_info() messages to print the refcount after device_find_child() (lines: 1937,2009), and after put_device() (lines: 1947, 2021). Boot the machine *without* put_device().

2013-04-11tty: serial/samsung: fix modular buildArnd Bergmann2-3/+5
There are a few bugs in the samsung serial driver when built as a loadable module, which makes the console code unavailable, as well as giving no access to the 'printascii' early debug function.

2013-04-11tty: serial/samsung: make register definitions globalArnd Bergmann1-3/+3
The registers for the Samsung S3C serial port are currently defined in the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h file, which is not visible to multiplatform capable drivers. Unfortunately, it is not possible to move the file into a more local place as we should normally try to, because the same registers may be used in one of four places: * In the driver itself * In platform-independent ARM code for early debug output * In platform_data definitions * In the Samsung platform power management code I have also found no way to logically split out a platform_data file, other than possibly move everything into include/linux/platform_data, which also felt wrong. The only part of this file that makes sense to keep specific to the s3c24xx platform are the virtual and physical addresses defined here, which are needed in no other location.
