* tipc: fix race condition at topology server receiveJon Maloy2018-01-163-46/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have identified a race condition during reception of socket events and messages in the topology server. - The function tipc_close_conn() is releasing the corresponding struct tipc_subscriber instance without considering that there may still be items in the receive work queue. When those are scheduled, in the function tipc_receive_from_work(), they are using the subscriber pointer stored in struct tipc_conn, without first checking if this is valid or not. This will sometimes lead to crashes, as the next call of tipc_conn_recvmsg() will access the now deleted item. We fix this by making the usage of this pointer conditional on whether the connection is active or not. I.e., we check the condition test_bit(CF_CONNECTED) before making the call tipc_conn_recvmsg(). - Since the two functions may be running on different cores, the condition test described above is not enough. tipc_close_conn() may come in between and delete the subscriber item after the condition test is done, but before tipc_conn_recv_msg() is finished. This happens less frequently than the problem described above, but leads to the same symptoms. We fix this by using the existing sk_callback_lock for mutual exclusion in the two functions. In addition, we have to move a call to tipc_conn_terminate() outside the mentioned lock to avoid deadlock.

Standard ARRAY_SIZE is now used through all the code, some unused abstraction structures removed and cleaned up, duplicate declarations removed. Also two large declaration styling fixes: - Hardware register set defines are lined up with kernel style - Hardware access functions were not prefixed, now already defined hw_atl prefix is used. patch v2 changes: - patch reorganized because of its big size. New HW support will be submitted as a separate patchset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

For example, unified hash-based memory can be used for many lookup purposes, like FDB and LPM. In many cases the user can provide a partitioning scheme for such a resource in order to perform fine tuning for his application. In such cases performing driver reload is needed for the changes to take place, thus this patchset also adds support for hot reload. Such an abstraction can be coupled with devlink's dpipe interface, which models the ASIC's pipeline as a graph of match/action tables. By modeling the hardware resource object, and by coupling it to several dpipe tables, further visibility can be achieved in order to debug ASIC-wide issues. The proposed interface will provide the user the ability to understand the limitations of the hardware, and receive notification regarding its occupancy. Furthermore, monitoring the resource occupancy can be done in real-time and can be useful in many cases. --- v2->v3 - Mix/Max/Gran attributes. - Add resource consumption per table. - Change basic resource unit to 'entry'. - ABI documentation. v1->v2 - Add resource size attribute. - Fix split bug. ==================== Signed-off-by: David S.

Business as usual and nothing special really standing out. But what's noteworthy here is that Larry Finger is stepping down as the rtlwifi maintainer. He has been maintaining rtlwifi since it was applied back in 2010 in commit 0c8173385e54 ("rtl8192ce: Add new driver") and it has been no easy role trying to juggle between the vendor, demanding upstream community and users. So big thank you to Larry for all his efforts! ath10k * more preparation work for wcn3990 support * add memory dump to firmware coredump files wil6210 * support scheduled scan * support 40-bit DMA addresses qtnfmac * support MAC address based access control * support for radar detection and Channel Availibility Check (CAC) mwifiex * firmware coredump for usb devices rtlwifi * Larry Finger steps down as the maintainer and Ping-Ke Shih becomes the new maintainer * add debugfs interfaces to dump register and btcoex status, and also write registers and h2c ==================== Signed-off-by: David S.

| * | b43: Replace mdelay with usleep_range in b43_radio_2057_init_postJia-Ju Bai2018-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | b43_radio_2057_init_post is not called in an interrupt handler nor holding a spinlock. The function mdelay in it can be replaced with usleep_range, to reduce busy wait.
