Ulf Hansson authored
This reverts commit 419dd626. It turned out that the change from the reverted commit breaks the ACPI based rpi's because it causes the 100Mhz max clock to be overridden to the return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a OF/DT based clock device.

Pull arm64 fix from Will Deacon: "We received a report this week that the generic version of pfn_valid(), which we switched to this merge window in 16c9afc7 ("arm64/mm: drop HAVE_ARCH_PFN_VALID"), interacts badly with dma_map_resource() due to the following check: /* Don't allow RAM to be mapped */ if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr)))) return DMA_MAPPING_ERROR; Since the ongoing saga to determine the semantics of pfn_valid() is unlikely to be resolved this week (does it indicate valid memory, or just the presence of a struct page, or whether that struct page has been initialised?), just revert back to our old version of pfn_valid() for 5.14.

Pull btrfs fix from David Sterba: "One more fix that I think qualifies for a late merge. It's a revert of a one-liner fix that meanwhile got backported to stable kernels and we got reports from users.

Currently, when query PFC configuration by dcbtool, driver will return PFC enable status based on TC. As all priorities are mapped to TC0 by default, if TC0 is enabled, then all priorities mapped to TC0 will be shown as enabled status when query PFC setting, even though some priorities have never been set. for example: $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off $ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on To fix this problem, just returns user's PFC config parameter saved in driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an unknown speed, and then this port can not work. The driver notify netif_carrier_on() before update the link state, when the bond receive carrier on, will query the speed of the port, if the query operation happens before updating the link state, will get an unknown speed. So need to notify netif_carrier_on() after update the link state.

Currently when device is moved between network namespaces using RTM_NEWLINK message type and one of netns attributes (FLA_NET_NS_PID, IFLA_NET_NS_FD, IFLA_TARGET_NETNSID) but w/o specifying IFLA_IFNAME, and target namespace already has device with same name, userspace will get EINVAL what is confusing and makes debugging harder. Fix it so that userspace gets more appropriate EEXIST instead what makes debugging much easier. Before: # ./ifname.sh + ip netns add ns0 + ip netns exec ns0 ip link add l0 type dummy + ip netns exec ns0 ip link show l0 8: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 66:90:b5:d5:78:69 brd ff:ff:ff:ff:ff:ff + ip link add l0 type dummy + ip link show l0 10: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 6e:c6:1f:15:20:8d brd ff:ff:ff:ff:ff:ff + ip link set l0 netns ns0 RTNETLINK answers: Invalid argument After: # ./ifname.sh + ip netns add ns0 + ip netns exec ns0 ip link add l0 type dummy + ip netns exec ns0 ip link show l0 8: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 1e:4a:72:e3:e3:8f brd ff:ff:ff:ff:ff:ff + ip link add l0 type dummy + ip link show l0 10: l0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether f2:fc:fe:2b:7d:a6 brd ff:ff:ff:ff:ff:ff + ip link set l0 netns ns0 RTNETLINK answers: File exists The problem is that do_setlink() passes its `char *ifname` argument, that it gets from a caller, to __dev_change_net_namespace() as is (as `const char *pat`), but semantics of ifname and pat can be different. For example, __rtnl_newlink() does this: net/core/rtnetlink.c 3270 char ifname[IFNAMSIZ]; ... 3286 if (tb[IFLA_IFNAME]) 3287 nla_strscpy(ifname, tb[IFLA_IFNAME], IFNAMSIZ); 3288 else 3289 ifname[0] = '\0'; ... 3364 if (dev) { ... 3394 return do_setlink(skb, dev, ifm, extack, tb, ifname, status); 3395 } , i.e. do_setlink() gets ifname pointer that is always valid no matter if user specified IFLA_IFNAME or not and then do_setlink() passes this ifname pointer as is to __dev_change_net_namespace() as pat argument. But the pat (pattern) in __dev_change_net_namespace() is used as: net/core/dev.c 11198 err = -EEXIST; 11199 if (__dev_get_by_name(net, dev->name)) { 11200 /* We get here if we can't use the current device name */ 11201 if (!pat) 11202 goto out; 11203 err = dev_get_valid_name(net, dev, pat); 11204 if (err < 0) 11205 goto out; 11206 } As the result the `goto out` path on line 11202 is neven taken and instead of returning EEXIST defined on line 11198, __dev_change_net_namespace() returns an error from dev_get_valid_name() and this, in turn, will be EINVAL for ifname[0] = '\0' set earlier.

Kurt Kanzenbach authored
Traffic schedules can only be started up to eight seconds within the future. Therefore, the driver periodically checks every two seconds whether the admin base time provided by the user is inside that window. If so the schedule is started. Otherwise the check is deferred. However, according to the programming manual the look ahead window size should be four - not eight - seconds. By using the proposed value of four seconds starting a schedule at a specified admin base time actually works as expected.

This patch fixes the interchanged fetch of the CAN RX and TX error counters from the ESD_EV_CAN_ERROR_EXT message. The RX error counter is really in struct rx_msg::data[2] and the TX error counter is in struct rx_msg::data[3].
