commit d1901ef0 upstream. When a drive is marked write-mostly it should only be the target of reads if there is no other option. This behaviour was broken by commit 9dedf603 md/raid1: read balance chooses idlest disk for SSD which causes a write-mostly device to be *preferred* is some cases. Restore correct behaviour by checking and setting best_dist_disk and best_pending_disk rather than best_disk. We only need to test one of these as they are both changed from -1 or >=0 at the same time. As we leave min_pending and best_dist unchanged, any non-write-mostly device will appear better than the write-mostly device. Reported-by:

commit c2996cb2 upstream. The KSTK_EIP() and KSTK_ESP() macros should return the user program counter (PC) and stack pointer (A0StP) of the given task. These are used to determine which VMA corresponds to the user stack in /proc/<pid>/maps, and for the user PC & A0StP in /proc/<pid>/stat. However for Meta the PC & A0StP from the task's kernel context are used, resulting in broken output. For example in following /proc/<pid>/maps output, the 3afff000-3b021000 VMA should be described as the stack: # cat /proc/self/maps ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 And in the following /proc/<pid>/stat output, the PC is in kernel code (1074234964 = 0x40078654) and the A0StP is in the kernel heap (1335981392 = 0x4fa17550): # cat /proc/self/stat 51 (cat) R ... 1335981392 1074234964 ... Fix the definitions of KSTK_EIP() and KSTK_ESP() to use task_pt_regs(tsk)->ctx rather than (tsk)->thread.kernel_context. This gets the registers from the user context stored after the thread info at the base of the kernel stack, which is from the last entry into the kernel from userland, regardless of where in the kernel the task may have been interrupted, which results in the following more correct /proc/<pid>/maps output: # cat /proc/self/maps ... 0800b000-08070000 r-xp 00000000 00:02 207 /lib/libuClibc-0.9.34-git.so ... 100b0000-100b1000 rwxp 00000000 00:00 0 [heap] 3afff000-3b021000 rwxp 00000000 00:00 0 [stack] And /proc/<pid>/stat now correctly reports the PC in libuClibc (134320308 = 0x80190b4) and the A0StP in the [stack] region (989864576 = 0x3b002280): # cat /proc/self/stat 51 (cat) R ... 989864576 134320308 ...

commit dfcc70a8 upstream. For filesystems without separate project quota inode field in the superblock we just reuse project quota file for group quotas (and vice versa) if project quota file is allocated and we need group quota file. When we reuse the file, quota structures on disk suddenly have wrong type stored in d_flags though. Nobody really cares about this (although structure type reported to userspace was wrong as well) except that after commit 14bf61ff (quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units) assertion in xfs_qm_scall_getquota() started to trigger on xfs/106 test (apparently I was testing without XFS_DEBUG so I didn't notice when submitting the above commit). Fix the problem by properly resetting ddq->d_flags when running quotacheck for a quota file. Reported-by:

commit 9145736d upstream. 1. For an IPv4 ping socket, ping_check_bind_addr does not check the family of the socket address that's passed in. Instead, make it behave like inet_bind, which enforces either that the address family is AF_INET, or that the family is AF_UNSPEC and the address is 0.0.0.0. 2. For an IPv6 ping socket, ping_check_bind_addr returns EINVAL if the socket family is not AF_INET6. Return EAFNOSUPPORT instead, for consistency with inet6_bind. 3. Make ping_v4_sendmsg and ping_v6_sendmsg return EAFNOSUPPORT instead of EINVAL if an incorrect socket address structure is passed in. 4. Make IPv6 ping sockets be IPv6-only. The code does not support IPv4, and it cannot easily be made to support IPv4 because the protocol numbers for ICMP and ICMPv6 are different. This makes connect(::ffff:192.0.2.1) fail with EAFNOSUPPORT instead of making the socket unusable. Among other things, this fixes an oops that can be triggered by: int s = socket(AF_INET, SOCK_DGRAM, IPPROTO_ICMP); struct sockaddr_in6 sin6 = { .sin6_family = AF_INET6, .sin6_addr = in6addr_any, }; bind(s, (struct sockaddr *) &sin6, sizeof(sin6)); Change-Id: If06ca86d9f1e4593c0d6df174caca3487c57a241 Signed-off-by:

commit acf8dd0a upstream. If an over-MTU UDP datagram is sent through a SOCK_RAW socket to a UFO-capable device, ip_ufo_append_data() sets skb->ip_summed to CHECKSUM_PARTIAL unconditionally as all GSO code assumes transport layer checksum is to be computed on segmentation. However, in this case, skb->csum_start and skb->csum_offset are never set as raw socket transmit path bypasses udp_send_skb() where they are usually set. As a result, driver may access invalid memory when trying to calculate the checksum and store the result (as observed in virtio_net driver). Moreover, the very idea of modifying the userspace provided UDP header is IMHO against raw socket semantics (I wasn't able to find a document clearly stating this or the opposite, though). And while allowing CHECKSUM_NONE in the UFO case would be more efficient, it would be a bit too intrusive change just to handle a corner case like this. Therefore disallowing UFO for packets from SOCK_DGRAM seems to be the best option. Signed-off-by:

commit 2f1d8b9e upstream. Brian reported crashes using IPv6 traffic with macvtap/veth combo. I tracked the crashes in neigh_hh_output() -> memcpy(skb->data - HH_DATA_MOD, hh->hh_data, HH_DATA_MOD); Neighbour code assumes headroom to push Ethernet header is at least 16 bytes. It appears macvtap has only 14 bytes available on arches where NET_IP_ALIGN is 0 (like x86) Effect is a corruption of 2 bytes right before skb->head, and possible crashes if accessing non existing memory. This fix should also increase IPv4 performance, as paranoid code in ip_finish_output2() wont have to call skb_realloc_headroom() Reported-by:

commit d720d8ce upstream. With commit a7526eb5 (net: Unbreak compat_sys_{send,recv}msg), the MSG_CMSG_COMPAT flag is blocked at the compat syscall entry points, changing the kernel compat behaviour from the one before the commit it was trying to fix (1be374a0, net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg). On 32-bit kernels (!CONFIG_COMPAT), MSG_CMSG_COMPAT is 0 and the native 32-bit sys_sendmsg() allows flag 0x80000000 to be set (it is ignored by the kernel). However, on a 64-bit kernel, the compat ABI is different with commit a7526eb5. This patch changes the compat_sys_{send,recv}msg behaviour to the one prior to commit 1be374a0. The problem was found running 32-bit LTP (sendmsg01) binary on an arm64 kernel. Arguably, LTP should not pass 0xffffffff as flags to sendmsg() but the general rule is not to break user ABI (even when the user behaviour is not entirely sane).

commit 57e59563 upstream. Currently following race is possible in team: CPU0 CPU1 team_port_del team_upper_dev_unlink priv_flags &= ~IFF_TEAM_PORT team_handle_frame team_port_get_rcu team_port_exists priv_flags & IFF_TEAM_PORT == 0 return NULL (instead of port got from rx_handler_data) netdev_rx_handler_unregister The thing is that the flag is removed before rx_handler is unregistered. If team_handle_frame is called in between, team_port_exists returns 0 and team_port_get_rcu will return NULL. So do not check the flag here. It is guaranteed by netdev_rx_handler_unregister that team_handle_frame will always see valid rx_handler_data pointer. Signed-off-by:

But when namespace deleted OVS does not detach these vports, that results in dangling pointer to netdevice which causes kernel panic as follows.

Usage count = 2 The problem is when rtnl_configure_link() fails in rtnl_newlink(), we simply call unregister_device(), but for stacked device like vlan, we almost do nothing when we unregister the upper device, more work is done when we unregister the lower device, so call its ->dellink().

commit 3b471175 upstream. ipv6_cow_metrics() currently assumes only DST_HOST routes require dynamic metrics allocation from inetpeer. The assumption breaks when ndisc discovered router with RTAX_MTU and RTAX_HOPLIMIT metric. Refer to ndisc_router_discovery() in ndisc.c and note that dst_metric_set() is called after the route is created. This patch creates the metrics array (by calling dst_cow_metrics_generic) in ipv6_cow_metrics().

commit b10a0819 upstream. Currently maximum space limit quota format supports is in blocks however since we store space limits in bytes, this is somewhat confusing. So store the maximum limit in bytes as well. Also rename the field to match the new unit and related inode field to match the new naming scheme. Reviewed-by:
