David Howells [Tue, 6 Jan 2009 22:27:01 +0000]
CRED: Fix regression in cap_capable() as shown up by sys_faccessat() [ver #3]

Fix a regression in cap_capable() due to:

commit 3b11a1decef07c19443d24ae926982bc8ec9f4c0
Author: David Howells <dhowells@redhat.com>
Date:   Fri Nov 14 10:39:26 2008 +1100

    CRED: Differentiate objective and effective subjective credentials on a task

The problem is that the above patch allows a process to have two sets of
credentials, and for the most part uses the subjective credentials when
accessing current's creds.

There is, however, one exception: cap_capable(), and thus capable(), uses the
real/objective credentials of the target task, whether or not it is the current
task.

Ordinarily this doesn't matter, since usually the two cred pointers in current
point to the same set of creds.  However, sys_faccessat() makes use of this
facility to override the credentials of the calling process to make its test,
without affecting the creds as seen from other processes.

One of the things sys_faccessat() does is to make an adjustment to the
effective capabilities mask, which cap_capable(), as it stands, then ignores.

The affected capability check is in generic_permission():

if (!(mask & MAY_EXEC) || execute_ok(inode))
if (capable(CAP_DAC_OVERRIDE))
return 0;

This change passes the set of credentials to be tested down into the commoncap
and SELinux code.  The security functions called by capable() and
has_capability() select the appropriate set of credentials from the process
being checked.

This can be tested by compiling the following program from the XFS testsuite:

Eric Paris [Fri, 2 Jan 2009 22:40:06 +0000]
SELinux: shrink sizeof av_inhert selinux_class_perm and context

I started playing with pahole today and decided to put it against the
selinux structures.  Found we could save a little bit of space on x86_64
(and no harm on i686) just reorganizing some structs.

Object size changes:
av_inherit: 24 -> 16
selinux_class_perm: 48 -> 40
context: 80 -> 72

Admittedly there aren't many of av_inherit or selinux_class_perm's in
the kernel (33 and 1 respectively) But the change to the size of struct
context reverberate out a bit.  I can get some hard number if they are
needed, but I don't see why they would be.  We do change which cacheline
context->len and context->str would be on, but I don't see that as a
problem since we are clearly going to have to load both if the context
is to be of any value.  I've run with the patch and don't seem to be
having any problems.

An example of what's going on using struct av_inherit would be:

form: to:
struct av_inherit { struct av_inherit {
u16 tclass; const char **common_pts;
const char **common_pts; u32 common_base;
u32 common_base; u16 tclass;
};

(notice all I did was move u16 tclass to the end of the struct instead
of the beginning)

Memory layout before the change:
struct av_inherit {
u16 tclass; /* 2 */
/* 6 bytes hole */
const char** common_pts; /* 8 */
u32 common_base; /* 4 */
/* 4 byes padding */

/* size: 24, cachelines: 1 */
/* sum members: 14, holes: 1, sum holes: 6 */
/* padding: 4 */
};

Memory layout after the change:
struct av_inherit {
const char ** common_pts; /* 8 */
u32 common_base; /* 4 */
u16 tclass; /* 2 */
/* 2 bytes padding */

/* size: 16, cachelines: 1 */
/* sum members: 14, holes: 0, sum holes: 0 */

Fix a regression in cap_capable() due to:

commit 5ff7711e635b32f0a1e558227d030c7e45b4a465

    CRED: Differentiate objective and effective subjective credentials on a task

The problem is that the above patch allows a process to have two sets of

accessing current's creds.

Ordinarily this doesn't matter, since usually the two cred pointers in current
point to the same set of creds.  However, sys_faccessat() makes use of this
facility to override the credentials of the calling process to make its test,
without affecting the creds as seen from other processes.

One of the things sys_faccessat() does is to make an adjustment to the
effective capabilities mask, which cap_capable(), as it stands, then ignores.

The affected capability check is in generic_permission():

if (!(mask & MAY_EXEC) || execute_ok(inode))
if (capable(CAP_DAC_OVERRIDE))
return 0;

This change splits capable() from has_capability() down into the commoncap and
SELinux code.  The capable() security op now only deals with the current
process, and uses the current process's subjective creds.  A new security op -
task_capable() - is introduced that can check any task's objective creds.

strictly the capable() security op is superfluous with the presence of the
task_capable() op, however it should be faster to call the capable() op since
two fewer arguments need be passed down through the various layers.

This can be tested by compiling the following program from the XFS testsuite:

keys: fix sparse warning by adding __user annotation to cast

Fix the following sparse warning:

CC security/keys/key.o
    security/keys/keyctl.c:1297:10: warning: incorrect type in argument 2 (different address spaces)

    security/keys/keyctl.c:1297:10:    got char *<noident>

which appears to be caused by lack of __user annotation to the cast of
a syscall argument.

11 years agosmack: Add support for unlabeled network hosts and networks
Casey Schaufler [Wed, 31 Dec 2008 17:54:12 +0000]
smack: Add support for unlabeled network hosts and networks

Add support for unlabeled network hosts and networks.
Relies heavily on Paul Moore's netlabel support.

Creates a new entry in /smack called netlabel. Writes to /smack/netlabel
take the form:

    A.B.C.D LABEL
or
    A.B.C.D/N LABEL

where A.B.C.D is a network address, N is an integer between 0-32,
and LABEL is the Smack label to be used. If /N is omitted /32 is
assumed. N designates the netmask for the address. Entries are
matched by the most specific address/mask pair. 0.0.0.0/0 will
match everything, while 192.168.1.117/32 will match exactly one
host.

A new system label "@", pronounced "web", is defined. Processes
can not be assigned the web label. An address assigned the web
label can be written to by any process, and packets coming from
a web address can be written to any socket. Use of the web label
is a violation of any strict MAC policy, but the web label has
been requested many times.

The nltype entry has been removed from /smack. It did not work right
and the netlabel interface can be used to specify that all hosts
be treated as unlabeled.

CIPSO labels on incoming packets will be honored, even from designated
single label hosts. Single label hosts can only be written to by
processes with labels that can write to the label of the host.
Packets sent to single label hosts will always be unlabeled.

Once added a single label designation cannot be removed, however
the label may be changed.

The behavior of the ambient label remains unchanged.

Paul Moore [Wed, 31 Dec 2008 17:54:11 +0000]
selinux: Deprecate and schedule the removal of the the compat_net functionality

This patch is the first step towards removing the old "compat_net" code from
the kernel.  Secmark, the "compat_net" replacement was first introduced in
2.6.18 (September 2006) and the major Linux distributions with SELinux support
have transitioned to Secmark so it is time to start deprecating the "compat_net"
mechanism.  Testing a patched version of 2.6.28-rc6 with the initial release of
Fedora Core 5 did not show any problems when running in enforcing mode.

This patch adds an entry to the feature-removal-schedule.txt file and removes
the SECURITY_SELINUX_ENABLE_SECMARK_DEFAULT configuration option, forcing
Secmark on by default although it can still be disabled at runtime.  The patch
also makes the Secmark permission checks "dynamic" in the sense that they are
only executed when Secmark is configured; this should help prevent problems
with older distributions that have not yet migrated to Secmark.

Julia Lawall [Tue, 30 Dec 2008 00:49:22 +0000]
V4L/DVB (10130): use USB API functions rather than constants

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_is_isoc_in(epd)
usb_endpoint_is_isoc_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r1@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==
- \(USB_ENDPOINT_XFER_CONTROL\|0\))
+ usb_endpoint_xfer_control(epd)

@r5@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==

V4L/DVB (10125): em28xx: Don't do AC97 vendor detection for i2s audio devices

The current code was trying to query the AC97 registers for the vendor

in the dmesg output).  This was due to a bug in the way we did the check.

V4L/DVB (10119): em28xx: fix corrupted XCLK value

Correct problem introduced during the board refactoring where the XCLK
frequency would get zero'd out.  The sequence of events was as follows:

em28xx_pre_card_setup() called em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration
em28xx_pre_card_setup() would set the dev->board.xclk if not set
em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk
...
em28xx_card_setup() would call em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration (clearing out
 value of dev->board.xclk set in em28xx_pre_card_setup)
...
em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk
 (which now contains zero)

The change sets the default XCLK and I2C Clock fields in the board definition
inside of em28xx_set_model() so that subsequent calls do not cause the
values to be overwritten.

With the introduction of the format conversion support in soc-camera, we now
also have to take care to pass the correct pixel format to the camera driver
when calling its try_fmt() method.

V4L/DVB (10080): soc-camera: readability improvements, more strict operations checks

Simplify multiple drivers by replacing f->fmt.pix.* with a single pointer
dereference, merge some needlessly broken lines, verify host and camera
operations pointers on registration.

V4L/DVB (10078): video: add NV16 and NV61 pixel formats

This patch adds support for NV16 and NV61 pixel formats.

These pixel formats use two planes; one for 8-bit Y values and
one for interleaved 8-bit U and V values. NV16/NV61 formats are
very similar to NV12/NV21 with the exception that NV16/NV61 are
using the same number of lines for both planes. The difference
between NV16 and NV61 is the U and V byte order.

The fourcc values are extrapolated from the NV12/NV21 case.

V4L/DVB (10075): pxa-camera: setup the FIFO inactivity time-out register

Using PXA270's FIFO inactivity time-out register (CITOR) reduces FIFO overruns.
The time-out is calculated in CICLK / LCDCLK ticks and has to be longer than
one pixel time. For this we have to know the pixel clock frequency, which
usually is provided by the camera. We use the struct soc_camera_sense to
request PCLK frequency from the camera driver upon each data format change.
