The use of disable_irq inside the handler for the interrupt being

Phil Sutter [Thu, 5 Mar 2009 07:27:15 +0000]
Input: add driver for S1 button of rb532

Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.

This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state.  This procedure works fine and has been tested as part of
another, unpublished driver for this device.

[ARM] 5417/1: Set the correct cacheid for ARMv6 CPUs with ARMv7 style MMU

The cacheid_init() function assumes that if cpu_architecture() returns
7, the caches are VIPT_NONALIASING. The cpu_architecture() function
returns the version of the supported MMU features (e.g. TEX remapping)

Revert "menu: fix embedded menu snafu"

This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was
totally wrong - the "embedded" options still exists (very much so) even
on non-embedded platforms.

It's just that we don't bother with actually asking about them when
we're not embedded, we just take their default values (which is usually
'y' - the options add features that may not be worth it in a constrained
environment).

drm: Avoid client deadlocks when the master disappears.

This is done by
1) Wake up lock waiters when we close the master file descriptor.
   Not when the master structure is removed, since the latter
   requires the waiters themselves to release the refcount on the
   master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
   Normally these clients will get a SIGPIPE when the X server dies,
   but clients may also spin trying to grab the DRM lock, without

Roland McGrath [Sat, 28 Feb 2009 07:25:54 +0000]
x86-64: seccomp: fix 32/64 syscall hole

On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with
ljmp, and then use the "syscall" instruction to make a 64-bit system
call.  A 64-bit process make a 32-bit system call with int $0x80.

In both these cases under CONFIG_SECCOMP=y, secure_computing() will use
the wrong system call number table.  The fix is simple: test TS_COMPAT
instead of TIF_IA32.  Here is an example exploit:

/* test case for seccomp circumvention on x86-64

   There are two failure modes: compile with -m64 or compile with -m32.

   The -m64 case is the worst one, because it does "chmod 777 ." (could
   be any chmod call).  The -m32 case demonstrates it was able to do
   stat(), which can glean information but not harm anything directly.

   A buggy kernel will let the test do something, print, and exit 1; a
   fixed kernel will make it exit with SIGKILL before it does anything.

The CAFE chip is broken due to commit e809517f6fa5803a5a1cd5602.
Anton added a quirk here: http://lkml.org/lkml/2009/2/20/279 that fixes
CAFE's problem.  This adds the quirk for CAFE.

10 years agox86 mmiotrace: fix race with release_kmmio_fault_page()
Pekka Paalanen [Tue, 24 Feb 2009 19:44:15 +0000]
x86 mmiotrace: fix race with release_kmmio_fault_page()

There was a theoretical possibility to a race between arming a page in
post_kmmio_handler() and disarming the page in
release_kmmio_fault_page():

cpu0                             cpu1
------------------------------------------------------------------
mmiotrace shutdown
enter release_kmmio_fault_page
                                 fault on the page
                                 disarm the page
disarm the page
                                 handle the MMIO access
                                 re-arm the page
put the page on release list
remove_kmmio_fault_pages()
                                 fault on the page
                                 page not known to mmiotrace
                                 fall back to do_page_fault()
                                 *KABOOM*

(This scenario also shows the double disarm case which is allowed.)

Fixed by acquiring kmmio_lock in post_kmmio_handler() and checking
if the page is being released from mmiotrace.

r8169: read MAC address from EEPROM on init (2nd attempt)

This is 2nd attempt to implement the initialization/reading of MAC address
from EEPROM. The first used PCI's VPD and there were some problems, some
devices are not able to read EEPROM content by VPD. The 2nd one uses direct
access to EEPROM through bit-banging interface and my testing results seem
to be much better.

I tested 5 systems each with different Realtek NICs and I didn't find any
problem. AFAIK Francois's NICs also works fine.

Original description:
This fixes the problem when MAC address is set by ifconfig or by
ip link commands and this address is stored in the device after
reboot. The power-off is needed to get right MAC address.
This is problem when Xen daemon is running because it renames the device
name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF.
After reboot the device is still using FE:FF:FF:FF:FF:FF.

The netpoll entry checks are required to ensure that we don't

it only ever worked for the netif_receive_skb/netif_rx entry

have the check and therefore can trigger all sorts of weird

This patch adds the netpoll check to all entry points.

I'm still uneasy with receiving at all under netpoll (which
apparently is only used by the out-of-tree kdump code).  The
reason is it is perfectly legal to receive all data including
headers into highmem if netpoll is off, but if you try to do
that with netpoll on and someone gets a printk in an IRQ handler
