It creates a root directory directly in the the root of the debugfs filesystem and within that directories for each device, named after the device ID of the devices iwlwifi is attached to. In the cfg80211/mac80211 directory there's now a link to the toplevel iwlwifi debugfs directory to make it easier to find the debugfs files.

We almost never need to the Host Command that was sent while handling its response, but when we do need it, we see that the command has been modified. This mystery has been elucidated. The FH (our DMA engine) writes its meta data on the buffer in the DRAM. Of course it copies the buffer to the NIC first. This was known to happen for Tx command, but as a matter of fact, it happens to all TFD brought by the FH which doesn't care much about what it brings from DRAM to internal SRAM. So copy the Host Command to yet another buffer so that we can properly pass the buffer that was sent originally to the fw. Do that only if it was request by the user since very few flows need to get the HCMD sent in the response handler.

The code in tcp_rcv_established() tries to perform early DMA copy if applicable. It however does so without checking whether the userspace task is actually expecting the data in the buffer. This is not a problem under normal circumstances, but there is a corner case where this doesn't work -- and that's when MSG_TRUNC flag to recvmsg() is used. If the IOAT dma engine is not used, the code properly checks whether there is a valid ucopy.task and the socket is owned by userspace, but misses the check in the dmaengine case. This problem can be observed in real trivially -- for example 'tbench' is a good reproducer, as it makes a heavy use of MSG_TRUNC. On systems utilizing IOAT, you will soon find tbench waiting indefinitely in sk_wait_data(), as they have been already early-copied in tcp_rcv_established() using dma engine. This patch introduces the same check we are performing in the simple iovec copy case to the IOAT case as well. It fixes the indefinite recvmsg(MSG_TRUNC) hangs.

The dst_free() calls from free_fib_info_rcu() are clearly racy. We need instead regular dst refcounting (dst_release()) and make sure dst_release() is aware of RCU grace periods : Add DST_RCU_FREE flag so that dst_release() respects an RCU grace period before dst destruction for cached dst Introduce a new inet_sk_rx_dst_set() helper, using atomic_inc_not_zero() to make sure we dont increase a zero refcount (On a dst currently waiting an rcu grace period before destruction) rt_cache_route() must take a reference on the new cached route, and release it if was not able to install it.

Root of the problem was that now we also cache output routes (in nh_rth_output), we must use call_rcu() instead of call_rcu_bh() in rt_free(), because output route lookups are done in process context. Based on feedback and initial patch from David Miller (adding another call_rcu_bh() call in fib, but it appears it was not the right fix) I left the inet_sk_rx_dst_set() helper and added __rcu attributes to nh_rth_output and nh_rth_input to better document what is going on in this code.

Internal lsof uses inode numbers on socket fs to resolve the type of sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides such inode information. Unfortunately bluetooth related protocols don't provide such inode information. This patch series introduces /proc/net files for the protocols. This patch against af_bluetooth.c provides facility to the implementation of protocols. This patch extends bt_sock_list and introduces two exported function bt_procfs_init, bt_procfs_cleanup. The type bt_sock_list is already used in some of implementation of protocols. bt_procfs_init prepare seq_operations which converts protocol own bt_sock_list data to protocol own proc entry when the entry is accessed. What I, lsof user, need is just inode number of bluetooth socket. However, people may want more information. The bt_procfs_init takes a function pointer for customizing the show handler of seq_operations. In v4 patch, __acquires and __releases attributes are added to suppress sparse warning. Suggested by Andrei Emeltchenko. In v5 patch, linux/proc_fs.h is included to use PDE. Build error is reported by Fengguang Wu.

The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used.

Subject: b43: be more user friendly with PHY info MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First of all, use PHY names instead of magic numbers. It should make configuring kernel easier in case of not enabled PHY type support. Secondly, always print info about PHY. This is really basic info about hardware and quite important for the support level. Signed-off-by: Rafał Miłecki Signed-off-by: John W.

There is a corner case in which wmm queue becomes empty immediately after processing the packet(before 20msec) and there may be next packet coming after some time. In this case we should not resume scan operation. We will use new flag to check Tx traffic and resume scan operation only if there is no traffic for 200msec.
