Pull crypto fix from Herbert Xu: "This fixes a regression that arose from the change to add a crypto prefix to module names which was done to prevent the loading of arbitrary modules through the Crypto API. In particular, a number of modules were missing the crypto prefix which meant that they could no longer be autoloaded" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: add missing crypto module aliases

"sp->desc[i]" has 25 characters. "dev->name" has 15 characters. If we used all 15 characters then the sprintf() would overflow. I changed the "sprintf(sp->name, "%s Neterion %s"" to snprintf(), as well, even though it can't overflow just to be consistent.

Read OCP register 0xa43a~0xa43b would clear some flags which the hw would use, and it may let the device lost. However, the unit of reading is 4 bytes.

For ocp_write_word() and ocp_write_byte(), there is a generic_ocp_read() which is used to read the whole 4 byte data, keep the unchanged bytes, and modify the expected bytes. However, the "byen" could be used to determine which bytes of the 4 bytes to write, so the action could be removed. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

The driver connects and disconnects the PHY device whenever the net device is brought up and down. The ethtool get_settings, set_settings and nway_reset operations will dereference a null or dangling pointer if called while it is down. I think it would be preferable to keep the PHY connected, but there may be good reasons not to. As an immediate fix for this bug: - Set the phydev pointer to NULL after disconnecting the PHY - Change those three operations to return -ENODEV while the PHY is not connected Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S.

Currently net_device_ops::set_rx_mode is only implemented for chips with a TSU (multiple address table). However we do need to turn the PRM (promiscuous) flag on and off for other chips. - Remove the unlikely() from the TSU functions that we may safely call for chips without a TSU - Make setting of the MCT flag conditional on the tsu capability flag - Rename sh_eth_set_multicast_list() to sh_eth_set_rx_mode() and plumb it into both net_device_ops structures - Remove the previously-unreachable branch in sh_eth_rx_mode() that would otherwise reset the flags to defaults for non-TSU chips Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: David S.

I.e. one-to-many sockets in SCTP are not required to explicitly call into connect(2) or sctp_connectx(2) prior to data exchange. Instead, they can directly invoke sendmsg(2) and the SCTP stack will automatically trigger connection establishment through 4WHS via sctp_primitive_ASSOCIATE(). However, this in its current implementation is racy: INIT is being sent out immediately (as it cannot be bundled anyway) and the rest of the DATA chunks are queued up for later xmit when connection is established, meaning sendmsg(2) will return successfully. This behaviour can result in an undesired side-effect that the kernel made the application think the data has already been transmitted, although none of it has actually left the machine, worst case even after close(2)'ing the socket. Instead, when the association from client side has been shut down e.g. first gracefully through SCTP_EOF and then close(2), the client could afterwards still receive the server's INIT_ACK due to a connection with higher latency. This INIT_ACK is then considered out of the blue and hence responded with ABORT as there was no alive assoc found anymore. This can be easily reproduced f.e. with sctp_test application from lksctp. One way to fix this race is to wait for the handshake to actually complete. The fix defers waiting after sctp_primitive_ASSOCIATE() and sctp_primitive_SEND() succeeded, so that DATA chunks cooked up from sctp_sendmsg() have already been placed into the output queue through the side-effect interpreter, and therefore can then be bundeled together with COOKIE_ECHO control chunks. strace from example application (shortened): socket(PF_INET, SOCK_SEQPACKET, IPPROTO_SCTP) = 3 sendmsg(3, {msg_name(28)={sa_family=AF_INET, sin_port=htons(8888), sin_addr=inet_addr("192.168.1.115")}, msg_iov(1)=[{"hello", 5}], msg_controllen=0, msg_flags=0}, 0) = 5 sendmsg(3, {msg_name(28)={sa_family=AF_INET, sin_port=htons(8888), sin_addr=inet_addr("192.168.1.115")}, msg_iov(1)=[{"hello", 5}], msg_controllen=0, msg_flags=0}, 0) = 5 sendmsg(3, {msg_name(28)={sa_family=AF_INET, sin_port=htons(8888), sin_addr=inet_addr("192.168.1.115")}, msg_iov(1)=[{"hello", 5}], msg_controllen=0, msg_flags=0}, 0) = 5 sendmsg(3, {msg_name(28)={sa_family=AF_INET, sin_port=htons(8888), sin_addr=inet_addr("192.168.1.115")}, msg_iov(1)=[{"hello", 5}], msg_controllen=0, msg_flags=0}, 0) = 5 sendmsg(3, {msg_name(28)={sa_family=AF_INET, sin_port=htons(8888), sin_addr=inet_addr("192.168.1.115")}, msg_iov(0)=[], msg_controllen=48, {cmsg_len=48, cmsg_level=0x84 /* SOL_??? */, cmsg_type=, ...}, msg_flags=0}, 0) = 0 // graceful shutdown for SOCK_SEQPACKET via SCTP_EOF close(3) = 0 tcpdump before patch (fooling the application): 22:33:36.306142 IP 192.168.1.114.41462 > 192.168.1.115.8888: sctp (1) [INIT] [init tag: 3879023686] [rwnd: 106496] [OS: 10] [MIS: 65535] [init TSN: 3139201684] 22:33:36.316619 IP 192.168.1.115.8888 > 192.168.1.114.41462: sctp (1) [INIT ACK] [init tag: 3345394793] [rwnd: 106496] [OS: 10] [MIS: 10] [init TSN: 3380109591] 22:33:36.317600 IP 192.168.1.114.41462 > 192.168.1.115.8888: sctp (1) [ABORT] tcpdump after patch: 14:28:58.884116 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [INIT] [init tag: 438593213] [rwnd: 106496] [OS: 10] [MIS: 65535] [init TSN: 3092969729] 14:28:58.888414 IP 192.168.1.115.8888 > 192.168.1.114.35846: sctp (1) [INIT ACK] [init tag: 381429855] [rwnd: 106496] [OS: 10] [MIS: 10] [init TSN: 2141904492] 14:28:58.888638 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [COOKIE ECHO] , (2) [DATA] (B)(E) [TSN: 3092969729] [...] 14:28:58.893278 IP 192.168.1.115.8888 > 192.168.1.114.35846: sctp (1) [COOKIE ACK] , (2) [SACK] [cum ack 3092969729] [a_rwnd 106491] [#gap acks 0] [#dup tsns 0] 14:28:58.893591 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [DATA] (B)(E) [TSN: 3092969730] [...] 14:28:59.096963 IP 192.168.1.115.8888 > 192.168.1.114.35846: sctp (1) [SACK] [cum ack 3092969730] [a_rwnd 106496] [#gap acks 0] [#dup tsns 0] 14:28:59.097086 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [DATA] (B)(E) [TSN: 3092969731] [...] , (2) [DATA] (B)(E) [TSN: 3092969732] [...] 14:28:59.103218 IP 192.168.1.115.8888 > 192.168.1.114.35846: sctp (1) [SACK] [cum ack 3092969732] [a_rwnd 106486] [#gap acks 0] [#dup tsns 0] 14:28:59.103330 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [SHUTDOWN] 14:28:59.107793 IP 192.168.1.115.8888 > 192.168.1.114.35846: sctp (1) [SHUTDOWN ACK] 14:28:59.107890 IP 192.168.1.114.35846 > 192.168.1.115.8888: sctp (1) [SHUTDOWN COMPLETE] Looks like this bug is from the pre-git history museum. ;) Fixes: 08707d54 ("lksctp-2_5_31-0_5_1.patch") Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S.

This reverts commit da788acb. That commit tried to fix the section mismatch warning by moving the ppc_corenet_clk_driver struct to init section. This is definitely wrong because the kernel would free the memories occupied by this struct after boot while this driver is still registered in the driver core.

The arndale-octa board was giving "imprecise external aborts" during boot-up with MCPM enabled. CCI enablement of the boot cluster was found to be the cause of these aborts (possibly because the secure f/w was not allowing it). Hence, disable CCI for the arndale-octa board.

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux settings depending on the card state. This collides with a lot of assumptions. It only works when using the internal card-detect mechanism and breaks horribly when using either the normal card-detect via the slot-gpio function or via any other pin. Also there is of course no link between the mmc and jtag on the software-side, so the jtag clocks may very well be disabled when the card is ejected and the soc switches back to the jtag pinmux. Leaving the switching function enabled did result in mmc timeouts and rcu stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases, as we expect the devicetree to explicitly select either mmc or jtag pinmuxes anyway.

In addition to the problem Jeff Layton reported, I looked at the code and reproduced the same warning by subscribing and removing the genl family with a socket still open. This is a fairly tricky race which originates in the fact that generic netlink allows the family to go away while sockets are still open - unlike regular netlink which has a module refcount for every open socket so in general this cannot be triggered. Trying to resolve this issue by the obvious locking isn't possible as it will result in deadlocks between unregistration and group unbind notification (which incidentally lockdep doesn't find due to the home grown locking in the netlink table.) To really resolve this, introduce a "closing socket" reference counter (for generic netlink only, as it's the only affected family) in the core netlink code and use that in generic netlink to wait for all the sockets that are being closed at the same time as a generic netlink family is removed. This fixes the race that when a socket is closed, it will should call the unbind, but if the family is removed at the same time the unbind will not find it, leading to the warning. The real problem though is that in this case the unbind could actually find a new family that is registered to have a multicast group with the same ID, and call its mcast_unbind() leading to confusing. Also remove the warning since it would still trigger, but is now no longer a problem. This also moves the code in af_netlink.c to before unreferencing the module to avoid having the same problem in the normal non-genl case.
