For future simplification it is important that the hci_recv_frame function is no longer an inline function. So move it into the module itself and export it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Sending commands to a down interface results in a timeout while clearly it should just return ENETDOWN. When using the ioctls this works fine, but not when using the HCI sockets sendmsg interface. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Implement raw output callback which is used by hidraw to send raw data to the underlying device.

The /dev/vhci ops don't refer to the module and so it is possible to unload the module while the file descriptor is in use. This was an accidental removal after the cleanup. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Remove the empty ioctl which just returns -EINVAL. vfs_ioctl() will return -ENOTTY instead, but I doubt that any application will notice the difference :) Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Fix dma-api-checking warnings in Sun HME Sun HME driver is mapping the first fragment with dma_map_single and subsequent fragments with dma_map_page. It is unmapping all fragments with dma_unmap_single and that produces the warning. This patch changes it so that it unmaps only the first fragment with dma_unmap_single and subsequent fragments are unmapped with dma_unmap_page.

Eric Dumazet mentioned in a context of another problem: "Well, it seems NFS reuses its socket, so maybe we miss some cleaning as spotted in this old patch" I've not check under which conditions that actually happens but if true, we need to make sure we don't accidently leave stale hints behind when the write queue had to be purged (whether reusing with NFS can actually happen if purging took place is something I'm not sure of). ...At least it compiles.

Take advantage of the fact that an explicit rtnl_kill_links is unnecessary (and skipping it improves batching), as network namespace exit calls dellink on all remaining virtual devices, and rtnl_link_unregister calls dellink on all outstanding devices in that network namespace. To do this we need to leave the vlan proc directories in place until after network device exit time, which is done by using register_pernet_subsys instead of register_pernet_device.

This is a straightforward re-implementation of an earlier (year-old) patch that no longer applies cleanly, with permission of the original author (Adam Langley): http://thread.gmane.org/gmane.linux.network/102586 The principle difference is using a TCP option to carry the cookie nonce, instead of a user configured offset in the data.

Data structures are carefully composed to require minimal additions. For example, the struct tcp_options_received cookie_plus variable fits between existing 16-bit and 8-bit variables, requiring no additional space (taking alignment into consideration). There are no additions to tcp_request_sock, and only 1 pointer in tcp_sock. This is a significantly revised implementation of an earlier (year-old) patch that no longer applies cleanly, with permission of the original author (Adam Langley): http://thread.gmane.org/gmane.linux.network/102586 The principle difference is using a TCP option to carry the cookie nonce, instead of a user configured offset in the data. This is more flexible and less subject to user configuration error. Such a cookie option has been suggested for many years, and is also useful without SYN data, allowing several related concepts to use the same extension option. "Re: SYN floods (was: does history repeat itself?)", September 9, 1996. http://www.merit.net/mail.archives/nanog/1996-09/msg00235.html "Re: what a new TCP header might look like", May 12, 1998. ftp://ftp.isi.edu/end2end/end2end-interest-1998.mail These functions will also be used in subsequent patches that implement additional features.

Define sysctl (tcp_cookie_size) to turn on and off the cookie option default globally, instead of a compiled configuration option. Define per socket option (TCP_COOKIE_TRANSACTIONS) for setting constant data values, retrieving variable cookie values, and other facilities. Move inline tcp_clear_options() unchanged from net/tcp.h to linux/tcp.h, near its corresponding struct tcp_options_received (prior to changes).

Define (missing) hash message size for SHA1. Define hashing size constants specific to TCP cookies. Add new function: tcp_cookie_generator(). Maintain global secret values for tcp_cookie_generator(). This is a significantly revised implementation of earlier (15-year-old) Photuris [RFC-2522] code for the KA9Q cooperative multitasking platform. Linux RCU technique appears to be well-suited to this application, though neither of the circular queue items are freed. These functions will also be used in subsequent patches that implement additional features.

Add optional function parameters associated with sending SYNACK. These parameters are not needed after sending SYNACK, and are not used for retransmission. Avoids extending struct tcp_request_sock, and avoids allocating kernel memory. Also affects DCCP as it uses common struct request_sock_ops, but this parameter is currently reserved for future use.

Driver maps only some part of the MMIO bar 0 in case of NX2031. This is sufficient for tx and rx by the driver.

Some function pointers for a few PHY operations (for 82578 and 82567) and were set incorrectly causing functions to be executed that were accessing incorrect PHY register offsets for that particular device.

The workaround that detects the correct PHY ID when an initial read of the PHY ID registers returns an invalid one should retry up to ten times with a small delay between attempts using a single PHY address and then repeat using the remaining possible PHY addresses.

The function pointers for 8257x devices are not set.
