2008-07-14[Bluetooth] Store remote modem status for RFCOMM TTYMarcel Holtmann1-0/+1
When switching a RFCOMM socket to a TTY, the remote modem status might be needed later. Currently it is lost since the original configuration is done via the socket interface. So store the modem status and reply it when the socket has been converted to a TTY. Signed-off-by: Denis Kenzior <denis.kenzior@trolltech.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Add timestamp support to L2CAP, RFCOMM and SCOMarcel Holtmann1-0/+1
Enable the common timestamp functionality that the network subsystem provides for L2CAP, RFCOMM and SCO sockets. It is possible to either use SO_TIMESTAMP or the IOCTLs to retrieve the timestamp of the current packet. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Export details about authentication requirementsMarcel Holtmann2-4/+16
With the Simple Pairing support, the authentication requirements are an explicit setting during the bonding process. Track and enforce the requirements and allow higher layers like L2CAP and RFCOMM to increase them if needed. This patch introduces a new IOCTL that allows to query the current authentication requirements. It is also possible to detect Simple Pairing support in the kernel this way.

2008-07-14[Bluetooth] Use ACL config stage to retrieve remote featuresMarcel Holtmann2-1/+4
The Bluetooth technology introduces new features on a regular basis and for some of them it is important that the hardware on both sides support them. For features like Simple Pairing it is important that the host stacks on both sides have switched this feature on. To make valid decisions, a config stage during ACL link establishment has been introduced that retrieves remote features and if needed also the remote extended features (known as remote host features) before signalling this link as connected. This change introduces full reference counting of incoming and outgoing ACL links and the Bluetooth core will disconnect both if no owner of it is present. To better handle interoperability during the pairing phase the disconnect timeout for incoming connections has been increased to 10 seconds. This is five times more than for outgoing connections.

2008-07-14[Bluetooth] Track status of remote Simple Pairing modeMarcel Holtmann2-0/+8
The Simple Pairing process can only be used if both sides have the support enabled in the host stack. The current Bluetooth specification has three ways to detect this support. If an Extended Inquiry Result has been sent during inquiry then it is safe to assume that Simple Pairing is enabled. It is not allowed to enable Extended Inquiry without Simple Pairing. During the remote name request phase a notification with the remote host supported features will be sent to indicate Simple Pairing support. Also the second page of the remote extended features can indicate support for Simple Pairing. For all three cases the value of remote Simple Pairing mode is stored in the inquiry cache for later use.

2008-07-14[Bluetooth] Track status of Simple Pairing modeMarcel Holtmann2-0/+12
The Simple Pairing feature is optional and needs to be enabled by the host stack first. The Linux kernel relies on the Bluetooth daemon to either enable or disable it, but at any time it needs to know the current state of the Simple Pairing mode. So track any changes made by external entities and store the current mode in the HCI device structure. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Disable disconnect timer during Simple PairingMarcel Holtmann1-0/+11
During the Simple Pairing process the HCI disconnect timer must be disabled. The way to do this is by holding a reference count of the HCI connection. The Simple Pairing process on both sides starts with an IO Capabilities Request and ends with Simple Pairing Complete. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Make use of the default link policy settingsMarcel Holtmann1-0/+11
The Bluetooth specification supports the default link policy settings on a per host controller basis. For every new connection the link manager would then use these settings. It is better to use this instead of bothering the controller on every connection setup to overwrite the default settings. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Track connection packet type changesMarcel Holtmann2-0/+10
The connection packet type can be changed after the connection has been established and thus needs to be properly tracked to ensure that the host stack has always correct and valid information about it. On incoming connections the Bluetooth core switches the supported packet types to the configured list for this controller. However the usefulness of this feature has been questioned a lot. The general consent is that every Bluetooth host stack should enable as many packet types as the hardware actually supports and leave the decision to the link manager software running on the Bluetooth chip. When running on Bluetooth 2.0 or later hardware, don't change the packet type for incoming connections anymore. This hardware likely supports Enhanced Data Rate and thus leave it completely up to the link manager to pick the best packet type. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Disconnect when encryption gets disabledMarcel Holtmann1-5/+5
The Bluetooth specification allows to enable or disable the encryption of an ACL link at any time by either the peer or the remote device. If a L2CAP or RFCOMM connection requested an encrypted link, they will now disconnect that link if the encryption gets disabled. Higher protocols that don't care about encryption (like SDP) are not affected. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-07-14[Bluetooth] Enforce security for outgoing RFCOMM connectionsMarcel Holtmann1-0/+1
Recent tests with various Bluetooth headsets have shown that some of them don't enforce authentication and encryption when connecting. All of them leave it up to the host stack to enforce it. Non of them should allow unencrypted connections, but that is how it is. So in case the link mode settings require authentication and/or encryption it will now also be enforced on outgoing RFCOMM connections. Previously this was only done for incoming connections. This support has a small drawback from a protocol level point of view since the host stack can't really tell with 100% certainty if a remote side is already authenticated or not. So if both sides are configured to enforce authentication it will be requested twice. Most Bluetooth chips are caching this information and thus no extra authentication procedure has to be triggered over-the-air, but it can happen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Receiving packets while we are cleaning up a network namespace is a racy proposition. It is possible when the packet arrives that we have removed some but not all of the state we need to fully process it. We have the choice of either playing wack-a-mole with the cleanup routines or simply dropping packets when we don't have a network namespace to handle them. Since the check looks inexpensive in netif_receive_skb let's just drop the incoming packets. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2008-06-13tcp: Revert 'process defer accept as established' changes.David S. Miller2-3/+2
This reverts two changesets, ec3c0982a2dd1e671bad8e9d26c28dcba0039d87 ("[TCP]: TCP_DEFER_ACCEPT updates - process as established") and the follow-on bug fix 9ae27e0adbf471c7a6b80102e38e1d5a346b3b38 ("tcp: Fix slab corruption with ipv6 and tcp6fuzz"). This change causes several problems, first reported by Ingo Molnar as a distcc-over-loopback regression where connections were getting stuck. Ilpo Järvinen first spotted the locking problems. The new function added by this code, tcp_defer_accept_check(), only has the child socket locked, yet it is modifying state of the parent listening socket. Fixing that is non-trivial at best, because we can't simply just grab the parent listening socket lock at this point, because it would create an ABBA deadlock. The normal ordering is parent listening socket --> child socket, but this code path would require the reverse lock ordering. Next is a problem noticed by Vitaliy Gusev, he noted: ---------------------------------------- >--- a/net/ipv4/tcp_timer.c >+++ b/net/ipv4/tcp_timer.c >@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data) > goto death; > } > >+ if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) { >+ tcp_send_active_reset(sk, GFP_ATOMIC); >+ goto death; Here socket sk is not attached to listening socket's request queue. tcp_done() will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should release this sk) as socket is not DEAD. Therefore socket sk will be lost for freeing. ---------------------------------------- Finally, Alexey Kuznetsov argues that there might not even be any real value or advantage to these new semantics even if we fix all of the bugs: ---------------------------------------- Hiding from accept() sockets with only out-of-order data only is the only thing which is impossible with old approach. Is this really so valuable? My opinion: no, this is nothing but a new loophole to consume memory without control. ---------------------------------------- So revert this thing for now.

2008-04-29netfilter: nf_conntrack: padding breaks conntrack hash on ARMPhilip Craig1-10/+0
commit 0794935e "[NETFILTER]: nf_conntrack: optimize hash_conntrack()" results in ARM platforms hashing uninitialised padding. This padding doesn't exist on other architectures. Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure everything is initialised. There were only 4 bytes that NF_CT_TUPLE_U_BLANK() wasn't clearing anyway (or 12 bytes on ARM).

Fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=10556 where conn templates with protocol=IPPROTO_IP can oops backup box. Result from ip_vs_proto_get() should be checked because protocol value can be invalid or unsupported in backup. But for valid message we should not fail for templates which use IPPROTO_IP. Also, add checks to validate message limits and connection state. Show state NONE for templates using IPPROTO_IP. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

2008-04-28Audit: collect sessionid in netlink messagesEric Paris2-11/+13
Previously I added sessionid output to all audit messages where it was available but we still didn't know the sessionid of the sender of netlink messages. This patch adds that information to netlink messages so we can audit who sent netlink messages. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-04-22[IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu1-0/+3
As it stands it's impossible to use any authentication algorithms with an ID above 31 portably. It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.
