Untangling ima mess, part 1: alloc_file()

There are 2 groups of alloc_file() callers:
* ones that are followed by ima_counts_get
* ones giving non-regular files
So let's pull that ima_counts_get() into alloc_file();
it's a no-op in case of non-regular files.

ima: only insert at inode creation time

iints are supposed to be allocated when an inode is allocated (during
security_inode_alloc())  But we have code which will attempt to allocate
an iint during measurement calls.  If we couldn't allocate the iint and we
cared, we should have died during security_inode_alloc().  Not make the
code more complex and less efficient.

9 years agolis3: scale output values to mg
Samu Onkalo [Tue, 15 Dec 2009 02:01:46 +0000]
lis3: scale output values to mg

Report output values as 1/1000 of earth gravity.

Output values from lis3 can be read from sysfs position entry and from
input device.  Input device can be accessed as event device and as
joystick device.  Joystick device can be in two modes.  Meaning of the
output values varies from case to case depending on the chip type and
configuration (scale).  Only joystick interface in JS_CORR_BROKEN mode
returned somehow similar output values in different configurations.
Joystick device is in that state by default in case of lis3.

Position sysfs entry, input event device and raw joystick device have been
little bit broken since meaning of the output values has been varied
between 12 and 8 bit devices.  Applications which relayed on those methods
failed if the chip is different than the expected one.

This patch converts output values to mean similar thing in different
configurations.  Both 8 and 12 bit devices reports now same acceleration
values.  If somebody implements full scale support to the driver, output
values will still mean the same.  Scaling factor and input device range

9 years agolis3: selftest support
Samu Onkalo [Tue, 15 Dec 2009 02:01:43 +0000]
lis3: selftest support

Implement selftest feature as specified by chip manufacturer.  Control:
read selftest sysfs entry

Response: "OK x y z" or "FAIL x y z"

where x, y, and z are difference between selftest mode and normal mode.
Test is passed when values are within acceptance limit values.

Acceptance limits are provided via platform data.  See chip spesifications
for acceptance limits.  If limits are not properly set, OK / FAIL decision
is meaningless.  However, userspace application can still make decision
based on the numeric x, y, z values.

Selftest is meant for HW diagnostic purposes.  It is not meant to be
called during normal use of the chip.  It may cause false interrupt
events.  Selftest mode delays polling of the normal results but it doesn't
cause wrong values.  Chip must be in static state during selftest.  Any
acceration during the test causes most probably failure.

9 years agommc: add module parameter to set whether cards are assumed removable
Ben Hutchings [Tue, 15 Dec 2009 02:01:29 +0000]
mmc: add module parameter to set whether cards are assumed removable

Some people run general-purpose distribution kernels on netbooks with
a card that is physically non-removable or logically non-removable
(e.g. used for /home) and cannot be cleanly unmounted during suspend.
Add a module parameter to set whether cards are assumed removable or
non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME.

In general, it is not possible to tell whether a card present in an MMC
slot after resume is the same that was there before suspend.  So there are
two possible behaviours, each of which will cause data loss in some cases:

CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed
during suspend.  Any filesystem on them must be unmounted before suspend;
otherwise, buffered writes will be lost.

CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during
suspend.  They must not be swapped during suspend; otherwise, buffered
writes will be flushed to the wrong card.

Currently the choice is made at compile time and this allows that to be
overridden at module load time.

wishes to keep the whitespace at the beginning.

Thus we need to keep with and without checked whitespace trim function.
This patch adds a new strim() and changes ipr.c to use it.

André Goddard Rosa [Tue, 15 Dec 2009 02:01:06 +0000]
tree-wide: convert open calls to remove spaces to skip_spaces() lib function

Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.

It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
   text    data     bss     dec     hex filename
  64688     584     592   65864   10148 (TOTALS-BEFORE)
  64641     584     592   65817   10119 (TOTALS-AFTER)

Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".

and found occurrences of this pattern on 3 more files:

string: factorize skip_spaces and export it to be generally available

On the following sentence:
    while (*s && isspace(*s))
        s++;

If *s == 0, isspace() evaluates to ((_ctype[*s] & 0x20) != 0), which
evaluates to ((0x08 & 0x20) != 0) which equals to 0 as well.
If *s == 1, we depend on isspace() result anyway. In other words,
"a char equals zero is never a space", so remove this check.

Also, *s != 0 is most common case (non-null string).

9 years agovsprintf: reuse almost identical simple_strtoulX() functions
André Goddard Rosa [Tue, 15 Dec 2009 02:01:01 +0000]
vsprintf: reuse almost identical simple_strtoulX() functions

The difference between simple_strtoul() and simple_strtoull() is just
the size of the variable used to keep track of the sum of characters
converted to numbers:

unsigned long simple_strtoul() {...}
unsigned long long simple_strtoull(){...}

Both are same size on my Core 2/gcc 4.4.1.
Overflow condition is not checked on both functions, so an extremely large
string can break these functions so that they don't even notice it.

As we do not care for overflowing on these functions, always keep the sum
using the larger variable around (unsigned long long) on simple_strtoull()
and cast it to (unsigned long) on simple_strtoul(), which then becomes
just a wrapper around simple_strtoull().

Code size decreases by 304 bytes:
   text    data     bss     dec     hex filename
  15534       0       8   15542    3cb6 vsprintf.o (ex lib/lib.a-BEFORE)

vsprintf: factorize "(null)" string

This patchset reduces lib/lib.a code size by 482 bytes on my Core 2 with
gcc 4.4.1 even considering that it exports a newly defined function
skip_spaces() to drivers:

   text    data     bss     dec     hex filename
  64867     840     592   66299   102fb (TOTALS-lib.a-BEFORE)
  64641     584     592   65817   10119 (TOTALS-lib.a-AFTER)
and implements some code tidy up.

Besides reducing lib.a size, it converts many in-tree drivers to use the
newly defined function, which makes another small reduction on kernel size
overall when those drivers are used.

This patch:

Change "<NULL>" to "(null)", unifying 3 equal strings.
glibc also uses "(null)" for the same purpose.

It decreases code size by 7 bytes:

scripts/get_maintainer.pl: fix --non with --git-blame and cleanups

Fix email matching without name --n and --git-blame
   Using --non and --git-blame caused maintainer signature
   matching to fail.  Fixed that by adding 3rd argument to
   sub format_email to control show/hide name portion of address
Slurp -f file instead of reading line-by-line for K: pattern matching.
   Suggested by Wolfram Sang as more efficient
Refactor git command execution
   Break into 2 functions, execute/analyze
   Share code between --git and --git-blame
   Don't warn multiple times when git isn't installed
Improve stats reporting
   --git-min-percent and -- rolestats now count the total number of commits
   for either the period of --git-since or if using --git-blame the commits
   used by the current file and calculate commit % as
      # of commits signed / total commits * 100
Code style cleaning
   Use consistent sub foo { my (args...) = @_;

9 years agoscripts/get_maintainer.pl: add --roles and --rolestats
Joe Perches [Tue, 15 Dec 2009 02:00:46 +0000]
scripts/get_maintainer.pl: add --roles and --rolestats

--roles shows the role of each email address, i.e. why it was selected.
--rolestats selects --roles and adds git log/blame signers #'s and %

Multiple roles are possible (supporter, maintainer, git-signer...)

--roles or --rolestats is meant to help identify appropriate maintainers
to notify and should not be used with "git send-email --cc-cmd"

9 years agovt: introduce and use vt_kmsg_redirect() function
Bernhard Walle [Tue, 15 Dec 2009 02:00:43 +0000]
vt: introduce and use vt_kmsg_redirect() function

The kernel offers with TIOCL_GETKMSGREDIRECT ioctl() the possibility to
redirect the kernel messages to a specific console.

However, since it's not possible to switch to the kernel message console
after a panic(), it would be nice if the kernel would print the panic
message on the current console.

This patch series adds a new interface to access the global kmsg_redirect
variable by a function to be able to use it in code where
CONFIG_VT_CONSOLE is not set (kernel/panic.c).

This patch:

Instead of using and exporting a global value kmsg_redirect, introduce a
function vt_kmsg_redirect() that both can set and return the console where
messages are printed.

Change all users of kmsg_redirect (the VT code itself and kernel/power.c)
to the new interface.

The main advantage is that vt_kmsg_redirect() can also be used when
CONFIG_VT_CONSOLE is not set.

9 years agocs5535: drop the Geode-specific MFGPT/GPIO code

cs5535: drop the Geode-specific MFGPT/GPIO code

With generic modular drivers handling all of this stuff, the
geode-specific code can go away.  The cs5535-gpio, cs5535-mfgpt, and
cs5535-clockevt drivers now handle this.
