previous commit 3fb72f1e makes IP-Config wait for carrier on at least one network device. Before waiting (predefined value 120s), check that at least one device was successfully brought up. Otherwise (e.g. buggy bootloader which does not set the MAC address) there is no point in waiting for carrier.

When checking whether a DATA chunk fits into the estimated rwnd a full sizeof(struct sk_buff) is added to the needed chunk size. This quickly exhausts the available rwnd space and leads to packets being sent which are much below the PMTU limit. This can lead to much worse performance. The reason for this behaviour was to avoid putting too much memory pressure on the receiver. The concept is not completely irational because a Linux receiver does in fact clone an skb for each DATA chunk delivered. However, Linux also reserves half the available socket buffer space for data structures therefore usage of it is already accounted for. When proposing to change this the last time it was noted that this behaviour was introduced to solve a performance issue caused by rwnd overusage in combination with small DATA chunks. Trying to reproduce this I found that with the sk_buff overhead removed, the performance would improve significantly unless socket buffer limits are increased. The following numbers have been gathered using a patched iperf supporting SCTP over a live 1 Gbit ethernet network. The -l option was used to limit DATA chunk sizes. The numbers listed are based on the average of 3 test runs each. Default values have been used for sk_(r|w)mem.

Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for limiting the autoclose value. If userspace passes in -1 on 32-bit platform, the overflow check didn't work and autoclose would be set to 0xffffffff. This patch defines a max_autoclose (in seconds) for limiting the value and exposes it through sysctl, with the following intentions. 1) Avoid overflowing autoclose * HZ. 2) Keep the default autoclose bound consistent across 32- and 64-bit platforms (INT_MAX / HZ in this patch). 3) Keep the autoclose value consistent between setsockopt() and getsockopt() calls.

When the last RFCOMM data channel is closed, a timer is normally set up to disconnect the control channel at a later time. If the control channel disconnect command is sent with the timer pending, the timer needs to be cancelled. If the timer is not cancelled in this situation, the reference counting logic for the RFCOMM session does not work correctly when the remote device closes the L2CAP connection. The session is freed at the wrong time, leading to a kernel panic. Signed-off-by: NMat Martineau <mathewm@codeaurora.org> Acked-by: NMarcel Holtmann <marcel@holtmann.org> Signed-off-by: NGustavo F.

This adds a default setting for semaphores parameter, and enables semaphores by default on IVB.
