2013-03-12tty/8250_pnp: serial port detection regression since v3.7Sean Young
The InsydeH2O BIOS (version dated 09/12/2011) has the following in its pnp resouces for its serial ports: $ cat /sys/bus/pnp/devices/00:0b/resources state = active io disabled irq disabled We do not check if the resources are disabled, and create a bogus ttyS* device. Since commit 835d844d1a28e (8250_pnp: do pnp probe before legacy probe) we get a bogus ttyS0, which prevents the legacy probe from detecting it. Note, the BIOS can also be upgraded, fixing this problem, but for people who can't do that, this fix is needed.

2013-03-12Fix 4 port and add support for 8 port 'Unknown' PCI serial port cardsScott Ashcroft
I've managed to find an 8 port version of the card 4 port card which was discussed here: http://marc.info/?l=linux-serial&m=120760744205314&w=2 Looking back at that thread there were two issues in the original patch. 1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post. 2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return. This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card. $ lspci -vvv -n -s 00:08.0 00:08.0 0780: 10b5:9050 (rev 01) Subsystem: 10b5:1588 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 17 Region 1: I/O ports at ff00 [size=128] Region 2: I/O ports at fe00 [size=64] Region 3: I/O ports at fd00 [size=8] Capabilities: <access denied> Kernel driver in use: serial $ dmesg | grep 0000:00:08.0: [ 0.083320] pci 0000:00:08.0: [10b5:9050] type 0 class 0x000780 [ 0.083355] pci 0000:00:08.0: reg 14: [io 0xff00-0xff7f] [ 0.083369] pci 0000:00:08.0: reg 18: [io 0xfe00-0xfe3f] [ 0.083382] pci 0000:00:08.0: reg 1c: [io 0xfd00-0xfd07] [ 0.083460] pci 0000:00:08.0: PME# supported from D0 D3hot [ 1.212867] 0000:00:08.0: ttyS4 at I/O 0xfe00 (irq = 17) is a 16550A [ 1.233073] 0000:00:08.0: ttyS5 at I/O 0xfe08 (irq = 17) is a 16550A [ 1.253270] 0000:00:08.0: ttyS6 at I/O 0xfe10 (irq = 17) is a 16550A [ 1.273468] 0000:00:08.0: ttyS7 at I/O 0xfe18 (irq = 17) is a 16550A [ 1.293666] 0000:00:08.0: ttyS8 at I/O 0xfe20 (irq = 17) is a 16550A [ 1.313863] 0000:00:08.0: ttyS9 at I/O 0xfe28 (irq = 17) is a 16550A [ 1.334061] 0000:00:08.0: ttyS10 at I/O 0xfe30 (irq = 17) is a 16550A [ 1.354258] 0000:00:08.0: ttyS11 at I/O 0xfe38 (irq = 17) is a 16550A Signed-off-by: Scott Ashcroft <scott.ashcroft@talk21.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-03-12tty: serial: mpc5xxx: fix PSC clock name bugAnatolij Gustschin
mpc512x platform clock code names PSC clocks as "pscX_mclk" but the driver tries to get "pscX_clk" clock and this results in errors like: mpc52xx-psc-uart 80011700.psc: Failed to get PSC clock entry! The problem appears when opening ttyPSC devices other than the system's serial console. Since getting and enabling the PSC clock fails, uart port startup doesn't succeed and tty flag TTY_IO_ERROR remains set causing further errors in tty ioctls, i.e. 'strace stty -F /dev/ttyPSC1' shows: open("/dev/ttyPSC1", O_RDONLY|O_NONBLOCK|O_LARGEFILE) = 3 dup2(3, 0) = 0 close(3) = 0 fcntl64(0, F_GETFL) = 0x10800 (flags O_RDONLY|O_NONBLOCK|O_LARGEFILE) fcntl64(0, F_SETFL, O_RDONLY|O_LARGEFILE) = 0 ioctl(0, TCGETS, 0xbff89038) = -1 EIO (Input/output error) Only request PSC clock names that the platform actually provides.

2013-03-12Input: add IMS Passenger Control Unit driverDmitry Torokhov
The PCU is a device installed in the armrest of a plane seat and is connected to IMS Rave Entertainment System. It has a set of control buttons (Volume Up/Down, Attendant, Lights, etc) on one side and gamepad-like controls on the other side. Originally the device was handled from userspace and because of that it presents itself on USB bus as a CDC-ACM modem device that however can not make calls. However the custom handling is not as convenient as using standard input subsystem facilities. If it was pure input device it would be possible to continue using userspace solution (moving it over to uinput), but the device also has backlighted keys which can not be supported via uinput.

2013-03-12Input: wm97xx - drop out of range inputsMarkus Pargmann
With fast movements, there occured some out of screen jumps with my touchscreen. The abs_x and abs_y module parameters should fix this by default, but the driver doesn't actively checks the x/y coordinates. Instead it seems that the input layer was supposed to drop out of range inputs, as described in the comments: "These parameters are used to help the input layer discard out of range readings and reduce jitter etc" The input layer documentation describes that values that are not in the absolute range are also accepted. So this patch adds a check within the driver.

2013-03-12ALSA: hda - Fix snd_hda_get_num_raw_conns() to return a correct valueTakashi Iwai
In the connection list expansion in hda_codec.c and hda_proc.c, the value returned from snd_hda_get_num_raw_conns() is used as the array size to store the connection list. However, the function returns simply a raw value of the AC_PAR_CONNLIST_LEN parameter, and the widget list with ranges isn't considered there. Thus it may return a smaller size than the actual list, which results in -ENOSPC in snd_hda_get_raw_conections(). This patch fixes the bug by parsing the connection list correctly also for snd_hda_get_num_raw_conns().

2013-03-12vfs: fix pipe counter breakageAl Viro
If you open a pipe for neither read nor write, the pipe code will not add any usage counters to the pipe, causing the 'struct pipe_inode_info" to be potentially released early. That doesn't normally matter, since you cannot actually use the pipe, but the pipe release code - particularly fasync handling - still expects the actual pipe infrastructure to all be there. And rather than adding NULL pointer checks, let's just disallow this case, the same way we already do for the named pipe ("fifo") case. This is ancient going back to pre-2.4 days, and until trinity, nobody naver noticed. Reported-by: Dave Jones <davej@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-03-12keys: fix race with concurrent install_user_keyrings()David Howells
This fixes CVE-2013-1792. There is a race in install_user_keyrings() that can cause a NULL pointer dereference when called concurrently for the same user if the uid and uid-session keyrings are not yet created. It might be possible for an unprivileged user to trigger this by calling keyctl() from userspace in parallel immediately after logging in. Assume that we have two threads both executing lookup_user_key(), both looking for KEY_SPEC_USER_SESSION_KEYRING. THREAD A THREAD B =============================== =============================== ==>call install_user_keyrings(); if (!cred->user->session_keyring) ==>call install_user_keyrings() ... user->uid_keyring = uid_keyring; if (user->uid_keyring) return 0; <== key = cred->user->session_keyring [== NULL] user->session_keyring = session_keyring; atomic_inc(&key->usage); [oops] At the point thread A dereferences cred->user->session_keyring, thread B hasn't updated user->session_keyring yet, but thread A assumes it is populated because install_user_keyrings() returned ok. The race window is really small but can be exploited if, for example, thread B is interrupted or preempted after initializing uid_keyring, but before doing setting session_keyring. This couldn't be reproduced on a stock kernel. However, after placing systemtap probe on 'user->session_keyring = session_keyring;' that introduced some delay, the kernel could be crashed reliably. Fix this by checking both pointers before deciding whether to return. Alternatively, the test could be done away with entirely as it is checked inside the mutex - but since the mutex is global, that may not be the best way.

ext3_msg() takes the printk prefix as the second parameter and the format string as the third parameter. Two callers of ext3_msg omit the prefix and pass the format string as the second parameter and the first parameter to the format string as the third parameter. In both cases this string comes from an arbitrary source. Which means the string may contain format string characters, which will lead to undefined and potentially harmful behavior.

2013-03-11xen: arm: mandate EABI and use generic atomic operations.Ian Campbell
Rob Herring has observed that c81611c4e96f "xen: event channel arrays are xen_ulong_t and not unsigned long" introduced a compile failure when building without CONFIG_AEABI: /tmp/ccJaIZOW.s: Assembler messages: /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]' Will Deacon pointed out that this is because OABI does not require even base registers for 64-bit values. We can avoid this by simply using the existing atomic64_xchg operation and the same containerof trick as used by the cmpxchg macros. However since this code is used on memory which is shared with the hypervisor we require proper atomic instructions and cannot use the generic atomic64 callbacks (which are based on spinlocks), therefore add a dependency on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much downside to this. While thinking about this we also observed that OABI has different struct alignment requirements to EABI, which is a problem for hypercall argument structs which are shared with the hypervisor and which must be in EABI layout. Since I don't expect people to want to run OABI kernels on Xen depend on CONFIG_AEABI explicitly too (although it also happens to be enforced by the !GENERIC_ATOMIC64 requirement too).

2013-03-11staging: comedi: dt9812: use CR_CHAN() for channel numberIan Abbott
As pointed out by Dan Carpenper in <http://driverdev.linuxdriverproject.org/pipermail/devel/2013-February/036025.html>, the dt9812 comedi driver's use of the `chanspec` member of `struct comedi_insn` as a channel number is incorrect. Change it to use `CR_CHAN(insn->chanspec)` as the channel number (where `insn` is a pointer to the `struct comedi_insn` being processed).

If the bootloader already enabled the display, the interrupt handler will be called as soon as it is registered. If the CRTC is not already added at this time, the call to imx_drm_handle_vblank will result in a NULL pointer dereference.
