When an object is created via a symlink into an audited directory, audit misses
the event due to not having collected the inode data for the directory. Modify

When the specified path is an existing file or when it is a symlink, audit
collects the wrong inode number, which causes it to miss the open() event.
Adding a second hook to the open() path fixes this.
Also add audit_copy_inode() to consolidate some code.

Suresh points out that commit b0423a0d9c
broke the semantics of a synchronous signal like SIGSEGV occurring
recursively inside its own handler handler (or, indeed, any other

That was unintentional, and this fixes things up by reinstating the old
semantics, but without reverting the cleanups.

Apparently some UHCI controllers change the value of the Short Packet
Detect (SPD) bit in the TD status word -- presumably when they receive a
short packet. This patch (as759) changes uhci-hcd to avoid assuming

When HZ is set to 250 (new default) or 100, the time span during which
repeated events from the device are ignored could be too small due to
ms->jiffies rounding. This causes the auto repeat to kick in early making
it impossible for the user to generate individual press/release events.

This patch adds a new unusual_devs flag for when usb-storage needs to ignore
a device that it would otherwise claim.
We need to ignore the ZyXEL G220F as it is a virtual CDROM drive which
includes the windows driver for this USB-WLAN adapter. After the windows
driver is installed on a windows system, it converts it into a WLAN adapter
(by ejecting the virtual disc).
The virtual CDROM is of no interest to Linux users. The zd1211rw driver will
automatically perform the eject operation, we just need to ensure that
usb-storage does not claim the device.

"SHARP WS003SH" has two modes, "Modem" and "ActiveSync".
But, "ActiveSync" mode uses NDIS connection.
Therefore, ipaq.c can only support "Modem" mode.

This patch implements a cleaner fix for the memory leak problem of the
original unix datagram getpeersec patch. Instead of creating a
security context each time a unix datagram is sent, we only create the
security context when the receiver requests it.
This new design requires modification of the current
unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely,
secid_to_secctx and release_secctx. The former retrieves the security
context and the latter releases it. A hook is required for releasing
the security context because it is up to the security module to decide
how that's done. In the case of Selinux, it's a simple kfree
operation.

The skb_queue_head_init() function is used both in drivers for private use
and in the core networking code. The usage models are vastly set of
functions that is only softirq safe; while the driver usage tends to be
more limited to a few hardirq safe accessor functions. Rather than
annotating all 133+ driver usages, for now just split this lock into a per
queue class. This change is obviously safe and probably should make

When I tested linux kernel 2.6.71.7 about statistics
"ipv6IfStatsOutFragCreates", and found that it couldn't increase
correctly. The criteria is RFC 2465:
ipv6IfStatsOutFragCreates OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of output datagram fragments that have
been generated as a result of fragmentation at
this output interface."
::= { ipv6IfStatsEntry 15 }
I think there are two issues in Linux kernel.
1st:
RFC2465 specifies the counter is "The number of output datagram
fragments...". I think increasing this counter after output a fragment
successfully is better. And it should not be increased even though a
fragment is created but failed to output.
2nd:
If we send a big ICMP/ICMPv6 echo request to a host, and receive
ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in
Linux kernel first fragmentation occurs in ICMP layer(maybe saying
transport layer is better), but this is not the "real"
fragmentation,just do some "pre-fragment" -- allocate space for date,
and form a frag_list, etc. The "real" fragmentation happens in IP layer
-- set offset and MF flag and so on. So I think in "fast path" for
ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by
upper layer we should also increase "ipv6IfStatsOutFragCreates".

We have a more complete solution in the works, involving
the seperation of CHECKSUM_HW on input vs. output, and
having netfilter properly do incremental checksums.
But that is a very involved patch and is thus 2.6.19
material.
What we have now is infinitely better than the past,
wherein all TSO packets were dropped due to corrupt
checksums as soon at the NAT module was loaded. At
least now, the checksums do get fixed up, it just
isn't the cleanest nor most optimal solution.
