When do cat /proc/net/netstat, the output isn't append with a new line, it looks like this: [root@localhost ~]# cat /proc/net/netstat ... MPTcpExt: 0 0 0 0 0 0 0 0 0 0 0 0 0[root@localhost ~]# This is because in mptcp_seq_show(), if mptcp isn't in use, net->mib.mptcp_statistics is NULL, so it just puts all 0 after "MPTcpExt:", and return, forgot the '\n'. After this patch: [root@localhost ~]# cat /proc/net/netstat ... MPTcpExt: 0 0 0 0 0 0 0 0 0 0 0 0 0 [root@localhost ~]# Fixes: fc518953 ("mptcp: add and use MIB counter infrastructure") Signed-off-by:

When enabling multicast snooping, bridge module deadlocks on multicast_lock if 1) IPv6 is enabled, and 2) there is an existing querier on the same L2 network. The deadlock was caused by the following sequence: While holding the lock, br_multicast_open calls br_multicast_join_snoopers, which eventually causes IP stack to (attempt to) send out a Listener Report (in igmp6_join_group). Since the destination Ethernet address is a multicast address, br_dev_xmit feeds the packet back to the bridge via br_multicast_rcv, which in turn calls br_multicast_add_group, which then deadlocks on multicast_lock. The fix is to move the call br_multicast_join_snoopers outside of the critical section. This works since br_multicast_join_snoopers only deals with IP and does not modify any multicast data structures of the bridge, so there's no need to hold the lock. Steps to reproduce: 1. sysctl net.ipv6.conf.all.force_mld_version=1 2. have another querier 3. ip link set dev bridge type bridge mcast_snooping 0 && \ ip link set dev bridge type bridge mcast_snooping 1 < deadlock > A typical call trace looks like the following: [ 936.251495] _raw_spin_lock+0x5c/0x68 [ 936.255221] br_multicast_add_group+0x40/0x170 [bridge] [ 936.260491] br_multicast_rcv+0x7ac/0xe30 [bridge] [ 936.265322] br_dev_xmit+0x140/0x368 [bridge] [ 936.269689] dev_hard_start_xmit+0x94/0x158 [ 936.273876] __dev_queue_xmit+0x5ac/0x7f8 [ 936.277890] dev_queue_xmit+0x10/0x18 [ 936.281563] neigh_resolve_output+0xec/0x198 [ 936.285845] ip6_finish_output2+0x240/0x710 [ 936.290039] __ip6_finish_output+0x130/0x170 [ 936.294318] ip6_output+0x6c/0x1c8 [ 936.297731] NF_HOOK.constprop.0+0xd8/0xe8 [ 936.301834] igmp6_send+0x358/0x558 [ 936.305326] igmp6_join_group.part.0+0x30/0xf0 [ 936.309774] igmp6_group_added+0xfc/0x110 [ 936.313787] __ipv6_dev_mc_inc+0x1a4/0x290 [ 936.317885] ipv6_dev_mc_inc+0x10/0x18 [ 936.321677] br_multicast_open+0xbc/0x110 [bridge] [ 936.326506] br_multicast_toggle+0xec/0x140 [bridge] Fixes: 4effd28c ("bridge: join all-snoopers multicast address") Signed-off-by:

hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings. Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry. Fixes: a582b78d ("net: hns3: code optimization for debugfs related to "dump reg"") Reported-by:

The current assumption is that the felix DSA driver has flooding knobs per traffic class, while ocelot switchdev has a single flooding knob. This was correct for felix VSC9959 and ocelot VSC7514, but with the introduction of seville VSC9953, we see a switch driven by felix.c which has a single flooding knob. So it is clear that we must do what should have been done from the beginning, which is not to overwrite the configuration done by ocelot.c in felix, but instead to teach the common ocelot library about the differences in our switches, and set up the flooding PGIDs centrally. The effect that the bogus iteration through FELIX_NUM_TC has upon seville is quite dramatic. ANA_FLOODING is located at 0x00b548, and ANA_FLOODING_IPMC is located at 0x00b54c. So the bogus iteration will actually overwrite ANA_FLOODING_IPMC when attempting to write ANA_FLOODING[1]. There is no ANA_FLOODING[1] in sevile, just ANA_FLOODING. And when ANA_FLOODING_IPMC is overwritten with a bogus value, the effect is that ANA_FLOODING_IPMC gets the value of 0x0003CF7D: MC6_DATA = 61, MC6_CTRL = 61, MC4_DATA = 60, MC4_CTRL = 0. Because MC4_CTRL is zero, this means that IPv4 multicast control packets are not flooded, but dropped. An invalid configuration, and this is how the issue was actually spotted. Reported-by:

During restarrt, mac80211 is supposed to reconfigure the driver. When there's a monitor interface, the interface is added and the channel context for it was created, but not assigned to it as it was not considered running during the restart. Fix this by setting SDATA_STATE_RUNNING while adding monitor interfaces. Signed-off-by:

STEs format for Connect-X5 and Connect-X6DX different. Currently, on Connext-X6DX the SW steering would break at some point when building STEs w/o giving a proper error message. Fix this by checking the STE format of the current device when initializing domain: add mlx5_ifc definitions for Connect-X6DX SW steering, read FW capability to get the current format version, and check this version when domain is being created.

The "skb" is freed by the transmit code in cxgb4_ofld_send() and we shouldn't use it again. But in the current code, if we hit an error later on in the function then the clean up code will call kfree_skb(skb) and so it causes a double free. Set the "skb" to NULL and that makes the kfree_skb() a no-op. Fixes: d25f2f71 ("crypto: chtls - Program the TLS session Key") Signed-off-by:

Currently .get_state() and .apply() use dev_get_drvdata() on the struct device related to the pwm chip. This only works after .probe() called platform_set_drvdata() which in this driver happens only after pwmchip_add() and so comes possibly too late. Instead of setting the driver data earlier use the traditional container_of approach as this way the driver data is conceptually and computational nearer.

Lilith >_> and Claudio Bozzato of Cisco Talos security team reported that collect_syscall() improperly casts the syscall registers to 64-bit values leaking the uninitialized last 24 bytes on 32-bit platforms, that are visible in /proc/self/syscall. The cause is that info->data.args are u64 while syscall_get_arguments() uses longs, as hinted by the bogus pointer cast in the function. Let's just proceed like the other call places, by retrieving the registers into an array of longs before assigning them to the caller's array. This was successfully tested on x86_64, i386 and ppc32.
