* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6:
security: fix up documentation for security_module_enable
Security: Introduce security= boot parameter
Audit: Final renamings and cleanup
SELinux: use new audit hooks, remove redundant exports
Audit: internally use the new LSM audit hooks
LSM/Audit: Introduce generic Audit LSM hooks
SELinux: remove redundant exports
Netlink: Use generic LSM hook
Audit: use new LSM hooks instead of SELinux exports
SELinux: setup new inode/ipc getsecid hooks
LSM: Introduce inode_getsecid and ipc_getsecid hooks
|

| |

| |

security_module_enable() can only be called during kernel init.

Add the security= boot parameter. This is done to avoid LSM
registration clashes in case of more than one bult-in module.
User can choose a security module to enable at boot. If no
security= boot parameter is specified, only the first LSM
asking for registration will be loaded. An invalid security
module name will be treated as if no module has been chosen.
LSM modules must check now if they are allowed to register
by calling security_module_enable(ops) first. Modify SELinux
and SMACK to do so.
Do not let SMACK register smackfs if it was not chosen on
boot. Smackfs assumes that smack hooks are registered and
the initial task security setup (swapper->security) is done.

Basically, use:

Introduce a generic Audit interface for security modules
by adding the following new LSM hooks:
audit_rule_init(field, op, rulestr, lsmrule)
audit_rule_known(krule)
audit_rule_match(secid, field, op, rule, actx)
audit_rule_free(rule)
Those hooks are only available if CONFIG_AUDIT is enabled.

SELinux interfaces.
Let {inode,ipc,task}_getsecid hooks set the secid to 0 by default
if CONFIG_SECURITY is not defined or if the hook is set to
NULL (dummy). This is done to notify the caller that no valid
secid exists.

This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89
aka "[NET]: Do not allocate unneeded memory for dev->priv alignment."
It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST
removal.
For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size"
was also 2048 bytes, but allocator with debugging options turned on started
giving out !32-byte aligned memory resulting in redzones overwrites.
Patch does small optimization in ->priv'less case: bumping size to next
32-byte boundary was always done to ensure ->priv will also be aligned.
But, no ->priv, no need to do that.

Fixes bugzilla #8895
If a super-tree leaf has 'rt' assigned to it and we
get an error from fib6_add_rt2node(), we'll leave
a reference to 'rt' in pn->leaf and then do an
unconditional dst_free().
We should prune such references.

dev_get_by_index() may return NULL if nothing is found. In
net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the
function is called, but the return value is never checked. If it returns
NULL then we'll deref a NULL pointer on the very next line.
I checked the callers, and I don't think this can actually happen today,
but code changes over time and in the future it might happen and it does
no harm to be defensive and check for the failure, so that if/when it
happens we'll fail gracefully instead of crashing.

As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.
Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
`- tcp_v4_syn_recv_sock
`- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.

The driver stores the PCI resource address into 'unsigned long' variable before
calling ioremap() on it. This warrants a kernel oops when the registers are
accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped
beyond 4 GB.
The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion of the
PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of
this trick, having instead CONFIG_RESOURCES_64BIT enabled.

drivers/net/sb1000.c has lots of inlined static functions.
Mst of them are used at initialization, wait for some
hardware register to change (wait using yield, sleep etc),
or do slow port-based I/O. Inlining thse "for speed" makes no sense.
This patch removes "inline" from biggest static function
(regardless of number of callsites - gcc nowadays auto-inlines
statics with one callsite).

Problem: If setting of an ip-address fails with LAN_OFFLINE,
qeth does not save the ip-address in its internal
list of set ip-addresses. qeth recovers after a
following STARTLAN event, but cannot set the unsaved
ip-address.
Solution: save the ip-address in the qeth-maintained list of
ip-addresses after a LAN_OFFLINE failure for SETIP.

Allocate headroom for TR_HLEN but using only ETH_HLEN causes rx
performance degradation. Allocate ETH_HLEN for ethernet and
TR_HLEN for token ring (layer 3 mode).

Symptom: slow CCL response time
Problem: non-ETH_P_802_2 packets are not delivered to NDH for
CCL. But CCL detects missing sequence numbers, which
cause a serious performance problem with CCL.
Solution: assign sequence numbers only to 802.2 packets.

Problem: A STARTLAN command from the adapter may arrive while a
qeth recovery is currently running with a failed qeth
STARTLAN. Usually qeth schedules a recovery when
receiving a STARTLAN command from the adapter. But
another recovery scheduled while a recovery is already
running never starts. Thus the qeth-administered
lan_online flag remains zero in this scenario, even
though the adapter-STARTLAN has happened.
Solution: Set lan_online flag for a received STARTLAN from the
adapter in case scheduled recovery does not start.
