2018-05-30qtnfmac: cleanup wdev structure between its usesSergey Matyukevich
Driver uses statically allocated wdev structures for each virtual interface. However wdev structure is not properly cleaned up between its uses. As a result, various bugs appear when userspace tools like hostapd were not gracefully stopped. In particular, this commit fixes the following issue: - start hostapd with more than 2 mBSS - kill hostapd using SIGKILL - start again hostapd with more than 2 mBSS However only two mBSS entities will be started: primary and the last BSS listed in hostapd config.

2018-05-30nbd: clear DISCONNECT_REQUESTED flag once disconnection occurs.Kevin Vigor
When a userspace client requests a NBD device be disconnected, the DISCONNECT_REQUESTED flag is set. While this flag is set, the driver will not inform userspace when a connection is closed. Unfortunately the flag was never cleared, so once a disconnect was requested the driver would thereafter never tell userspace about a closed connection. Thus when connections failed due to timeout, no attempt to reconnect was made and eventually the device would fail. Fix by clearing the DISCONNECT_REQUESTED flag (and setting the DISCONNECTED flag) once all connections are closed.

There is a race condition in tpm_common_write function allowing two threads on the same /dev/tpm<N>, or two different applications on the same /dev/tpmrm<N> to overwrite each other commands/responses.

There is no need for it to be atomic since it is only touched under the protection of the priv->buffer_mutex.

2018-05-31crypto: clarify licensing of OpenSSL asm codeAdam Langley
Several source files have been taken from OpenSSL. In some of them a comment that "permission to use under GPL terms is granted" was included below a contradictory license statement. In several cases, there was no indication that the license of the code was compatible with the GPLv2. This change clarifies the licensing for all of these files. I've confirmed with the author (Andy Polyakov) that a) he has licensed the files with the GPLv2 comment under that license and b) that he's also happy to license the other files under GPLv2 too. In one case, the file is already contained in his CRYPTOGAMS bundle, which has a GPLv2 option, and so no special measures are needed. In all cases, the license status of code has been clarified by making the GPLv2 license prominent. The .S files have been regenerated from the updated .pl files. This is a comment-only change.
