The NETLINK_F_LISTEN_ALL_NSID otion enables to listen all netns that have a nsid assigned into the netns where the netlink socket is opened. The nsid is sent as metadata to userland, but the existence of this nsid is checked only for netns that are different from the socket netns. Thus, if no nsid is assigned to the socket netns, NETNSA_NSID_NOT_ASSIGNED is reported to the userland. This value is confusing and useless. After this patch, only valid nsid are sent to userland.

Auto-loading of the Marvell DSA driver has stopped working with recent kernels. This seems to be due to the change of binding for DSA devices, moving them from the platform bus to the MDIO bus. In order for module auto-loading to work, we need to provide a MODALIAS string in the uevent file for the device. However, the device core does not automatically provide this, and needs each bus_type to implement a uevent method to generate these strings. The MDIO bus does not provide such a method, so no MODALIAS string is provided: .# cat /sys/bus/mdio_bus/devices/f1072004.mdio-mii\:04/uevent DRIVER=mv88e6085 OF_NAME=switch OF_FULLNAME=/soc/internal-regs/mdio@72004/switch@4 OF_COMPATIBLE_0=marvell,mv88e6085 OF_COMPATIBLE_N=1 In the case of OF-based devices, the solution is easy - of_device_uevent_modalias() does the work for us. After this is done, the uevent file looks like this: .# cat /sys/bus/mdio_bus/devices/f1072004.mdio-mii\:04/uevent DRIVER=mv88e6085 OF_NAME=switch OF_FULLNAME=/soc/internal-regs/mdio@72004/switch@4 OF_COMPATIBLE_0=marvell,mv88e6085 OF_COMPATIBLE_N=1 MODALIAS=of:NswitchT<NULL>Cmarvell,mv88e6085 which results in auto-loading of the Marvell DSA driver on Clearfog platforms.

MTU probing initialization occurred only at connect() and at SYN or SYN-ACK reception, but the former sets MSS to either the default or the user set value (through TCP_MAXSEG sockopt) and the latter never happens with repaired sockets. The result was that, with MTU probing enabled and unless TCP_MAXSEG sockopt was used before connect(), probing would be stuck at tcp_base_mss value until tcp_probe_interval seconds have passed.

Current implementation lacks the logic for providing management firmware with RDMA-related statistics; [much] worse than that - it logs such events by default to system logs. Since the statistics' gathering is done periodically, using sufficiently new management firmware the system logs would get filled with these unnecessary prints. For now, reduce the verbosity of the log so that it would not be logged by default. Fixes: 6c754246 ("qed: Add support for NCSI statistics") Signed-off-by:

During PCI error recovery process, specifically on eeh_err_detected() we might have a NULL netdev struct, hence a direct dereference will lead to a kernel oops. This was observed with latest upstream kernel (v4.12-rc2) on Chelsio adapter T422-CR in PowerPC machines. This patch checks for NULL pointer and avoids the crash, both in eeh_err_detected() and eeh_resume(). Also, we avoid to trigger a fatal error or to try disabling interrupts on FW during PCI error recovery, because: (a) driver might not be able to accurately access PCI regions in this case, and (b) trigger a fatal error _during_ the recovery steps is a mistake that could prevent the recovery path to complete successfully.

Andrey Konovalov reported crashes in ipv4_mtu() I could reproduce the issue with KASAN kernels, between 10.246.7.151 and 10.246.7.152 : 1) 20 concurrent netperf -t TCP_RR -H 10.246.7.152 -l 1000 & 2) At the same time run following loop : while : do ip ro add 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500 ip ro del 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500 done Cong Wang attempted to add back rt->fi in commit 82486aa6 ("ipv4: restore rt->fi for reference counting") but this proved to add some issues that were complex to solve. Instead, I suggested to add a refcount to the metrics themselves, being a standalone object (in particular, no reference to other objects) I tried to make this patch as small as possible to ease its backport, instead of being super clean. Note that we believe that only ipv4 dst need to take care of the metric refcount. But if this is wrong, this patch adds the basic infrastructure to extend this to other families.

This fix addresses two problems in the way the DSCP field is formulated on the encapsulating header of IPv6 tunnels. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661 1) The IPv6 tunneling code was manipulating the DSCP field of the encapsulating packet using the 32b flowlabel. Since the flowlabel is only the lower 20b it was incorrect to assume that the upper 12b containing the DSCP and ECN fields would remain intact when formulating the encapsulating header. This fix handles the 'inherit' and 'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable. 2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was incorrect and resulted in the DSCP value always being set to 0. Commit 90427ef5 ("ipv6: fix flow labels when the traffic class is non-0") caused the regression by masking out the flowlabel which exposed the incorrect handling of the DSCP portion of the flowlabel in ip6_tunnel and ip6_gre.

sometimes ICMP replies to INIT chunks are ignored by the client, even if the encapsulated SCTP headers match an open socket. This happens when the ICMP packet is carried by a paged skb: use skb_header_pointer() to read packet contents beyond the SCTP header, so that chunk header and initiate tag are validated correctly. v2: - don't use skb_header_pointer() to read the transport header, since icmp_socket_deliver() already puts these 8 bytes in the linear area. - change commit message to make specific reference to INIT chunks.

There is a race condition in llc_ui_bind if two or more processes/threads try to bind a same socket. If more processes/threads bind a same socket success that will lead to two problems, one is this action is not what we expected, another is will lead to kernel in unstable status or oops(in my simple test case, cause llc2.ko can't unload). The current code is test SOCK_ZAPPED bit to avoid a process to bind a same socket twice but that is can't avoid more processes/threads try to bind a same socket at the same time. So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect. Signed-off-by:
