* netfilter: nf_nat_sip: c= is optional for sessionHerbert Xu2008-07-211-13/+25
| | | | | | | | | | | | | | | | According to RFC2327, the connection information is optional in the session description since it can be specified in the media description instead. My provider does exactly that and does not provide any connection information in the session description. As a result the new kernel drops all invite responses.

* netfilter: accounting rework: ct_extend + 64bit counters (v4)Krzysztof Piotr Oledzki2008-07-218-69/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | Initially netfilter has had 64bit counters for conntrack-based accounting, but it was changed in 2.6.14 to save memory. Unfortunately in-kernel 64bit counters are still required, for example for "connbytes" extension. However, 64bit counters waste a lot of memory and it was not possible to enable/disable it runtime. This patch: - reimplements accounting with respect to the extension infrastructure, - makes one global version of seq_print_acct() instead of two seq_print_counters(), - makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n), - makes it possible to enable/disable it at runtime by sysctl or sysfs, - extends counters from 32bit to 64bit, - renames ip_conntrack_counter -> nf_conn_counter, - enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT), - set initial accounting enable state based on CONFIG_NF_CT_ACCT - removes buggy IPCT_COUNTER_FILLING event handling. If accounting is enabled newly created connections get additional acct extend. Old connections are not changed as it is not possible to add a ct_extend area to confirmed conntrack. Accounting is performed for all connections with acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When adapters have differing IRD limits, the RDMA transport will fail to connect properly. The RDMA transport should use the client's advertised inbound read limit when computing its outbound read limit. For iWARP transports, there is currently no standard for exchanging IRD/ORD during connection establishment so the 'responder_resources' field in the connect event is the local device's limit. The RDMA transport can be configured to use a smaller ORD by writing the desired number to the /proc/sys/sunrpc/svc_rdma/max_outbound_read_requests file.

Make it take a task arg and and get rid of the "oldmask" - have svc_set_num_threads call kthread_create directly - eliminate __svc_create_thread Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: J.

The BKL really isn't adequate for this job since some of this info needs protection across sleeps.

This mainly happens with the Handsfree profile where the remote side starts sending data right away. The problem is that these packets are in the socket receive queue. So when creating the TTY make sure to copy all pending packets from the socket receive queue to a private queue inside the TTY. To make this actually work, the flow control on the newly created TTY will be disabled and only enabled again when the TTY is opened by an application. And right before that, the pending packets will be put into the TTY flip buffer. Signed-off-by: Denis Kenzior <denis.kenzior@trolltech.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| | * | | [Bluetooth] Store remote modem status for RFCOMM TTYMarcel Holtmann2008-07-142-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * | | [Bluetooth] Use non-canonical TTY by default for RFCOMMMarcel Holtmann2008-07-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the RFCOMM TTY emulation can act like a real serial port, in reality it is not used like this. So to not mess up stupid applications, use the non-canonical mode by default. Signed-off-by: Denis Kenzior <denis.kenzior@trolltech.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With all the Bluetooth 2.1 changes and the support for Simple Pairing, it is important to update the Bluetooth core version number. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
| | * | | [Bluetooth] Use a more unique bus name for connectionsMarcel Holtmann2008-07-143-9/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When attaching Bluetooth low-level connections to the bus, the bus name is constructed from the remote address since at that time the connection handle is not assigned yet. This has worked so far, but also caused a lot of troubles. It is better to postpone the creation of the sysfs entry to the time when the connection actually has been established and then use its connection handle as unique identifier. This also fixes the case where two different adapters try to connect to the same remote device. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
