2020-09-18pNFS/flexfiles: Be consistent about mirror index typesTrond Myklebust
A mirror index is always of type u32. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2020-09-18pNFS/flexfiles: Ensure we initialise the mirror bsizes correctly on readTrond Myklebust
While it is true that reading from an unmirrored source always uses index 0, that is no longer true for mirrored sources when we fail over. Fixes: 563c53e73b8b ("NFS: Fix flexfiles read failover") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2020-09-18mac80211: fix 80 MHz association to 160/80+80 AP on 6 GHzJohn Crispin
When trying to associate to an AP support 180 or 80+80 MHz on 6 GHz with a STA that only has 80 Mhz support the cf2 field inside the chandef will get set causing the association to fail when trying to validate the chandef. Fix this by checking the support flags prior to setting cf2.

2020-09-18lib80211: fix unmet direct dependendices config warning when !CRYPTONecip Fazil Yildiran
When LIB80211_CRYPT_CCMP is enabled and CRYPTO is disabled, it results in unmet direct dependencies config warning. The reason is that LIB80211_CRYPT_CCMP selects CRYPTO_AES and CRYPTO_CCM, which are subordinate to CRYPTO. This is reproducible with CRYPTO disabled and R8188EU enabled, where R8188EU selects LIB80211_CRYPT_CCMP but does not select or depend on CRYPTO.

2020-09-18mac80211: extend AQL aggregation estimation to HE and fix unit mismatchFelix Fietkau
The unit of the return value of ieee80211_get_rate_duration is nanoseconds, not microseconds. Adjust the duration checks to account for that. For higher data rates, allow larger estimated aggregation sizes, and add some values for HE as well, which can use much larger aggregates. Since small packets with high data rates can now lead to duration values too small for info->tx_time_est, return a minimum of 4us.

2020-09-18iommu/amd: Restore IRTE.RemapEn bit for amd_iommu_activate_guest_modeSuravee Suthikulpanit
Commit e52d58d54a32 ("iommu/amd: Use cmpxchg_double() when updating 128-bit IRTE") removed an assumption that modify_irte_ga always set the valid bit, which requires the callers to set the appropriate value for the struct irte_ga.valid bit before calling the function. Similar to the commit 26e495f34107 ("iommu/amd: Restore IRTE.RemapEn bit after programming IRTE"), which is for the function amd_iommu_deactivate_guest_mode(). The same change is also needed for the amd_iommu_activate_guest_mode(). Otherwise, this could trigger IO_PAGE_FAULT for the VFIO based VMs with AVIC enabled.

2020-09-18x86/unwind/fp: Fix FP unwinding in ret_from_forkJosh Poimboeuf
There have been some reports of "bad bp value" warnings printed by the frame pointer unwinder: WARNING: kernel stack regs at 000000005bac7112 in sh:1014 has bad 'bp' value 0000000000000000 This warning happens when unwinding from an interrupt in ret_from_fork(). If entry code gets interrupted, the state of the frame pointer (rbp) may be undefined, which can confuse the unwinder, resulting in warnings like the above. There's an in_entry_code() check which normally silences such warnings for entry code. But in this case, ret_from_fork() is getting interrupted. It recently got moved out of .entry.text, so the in_entry_code() check no longer works. It could be moved back into .entry.text, but that would break the noinstr validation because of the call to schedule_tail(). Instead, initialize each new task's RBP to point to the task's entry regs via an encoded frame pointer. That will allow the unwinder to reach the end of the stack gracefully.

This came in as a code fix and not a bug report, so I don't think it was widely problematic. I believe it worked out due to it being memblock memory and alignment requirements working in our favor" * 'for-5.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: fix first chunk size calculation for populated bitmap

2020-09-17net: phy: Do not warn in phy_stop() on PHY_DOWNFlorian Fainelli
When phy_is_started() was added to catch incorrect PHY states, phy_stop() would not be qualified against PHY_DOWN. It is possible to reach that state when the PHY driver has been unbound and the network device is then brought down.

If we have unbound the PHY driver prior to calling phy_detach() (often via phy_disconnect()) then we can cause a NULL pointer de-reference accessing the driver owner member.

2020-09-17ethtool: add and use message type for tunnel info replyMichal Kubecek
Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd field in genetlink header) for replies to tunnel info netlink request, i.e. the same value as the request have. This is a problem because we are using two separate enums for userspace to kernel and kernel to userspace message types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for kernel to userspace messages. As the tunnel info request reached mainline in 5.9 merge window, we should still be able to fix the reply message type without breaking backward compatibility.

2020-09-17drivers/net/wan/hdlc: Set skb->protocol before transmittingXie He
This patch sets skb->protocol before transmitting frames on the HDLC device, so that a user listening on the HDLC device with an AF_PACKET socket will see outgoing frames' sll_protocol field correctly set and consistent with that of incoming frames. 1. Control frames in hdlc_cisco and hdlc_ppp When these drivers send control frames, skb->protocol is not set. This value should be set to htons(ETH_P_HDLC), because when receiving control frames, their skb->protocol is set to htons(ETH_P_HDLC). When receiving, hdlc_type_trans in hdlc.h is called, which then calls cisco_type_trans or ppp_type_trans. The skb->protocol of control frames is set to htons(ETH_P_HDLC) so that the control frames can be received by hdlc_rcv in hdlc.c, which calls cisco_rx or ppp_rx to process the control frames. 2. hdlc_fr When this driver sends control frames, skb->protocol is set to internal values used in this driver. When this driver sends data frames (from upper stacked PVC devices), skb->protocol is the same as that of the user data packet being sent on the upper PVC device (for normal PVC devices), or is htons(ETH_P_802_3) (for Ethernet-emulating PVC devices). However, skb->protocol for both control frames and data frames should be set to htons(ETH_P_HDLC), because when receiving, all frames received on the HDLC device will have their skb->protocol set to htons(ETH_P_HDLC). When receiving, hdlc_type_trans in hdlc.h is called, and because this driver doesn't provide a type_trans function in struct hdlc_proto, all frames will have their skb->protocol set to htons(ETH_P_HDLC). The frames are then received by hdlc_rcv in hdlc.c, which calls fr_rx to process the frames (control frames are consumed and data frames are re-received on upper PVC devices).

2020-09-17drivers/net/wan/lapbether: Make skb->protocol consistent with the headerXie He
This driver is a virtual driver stacked on top of Ethernet interfaces. When this driver transmits data on the Ethernet device, the skb->protocol setting is inconsistent with the Ethernet header prepended to the skb. This causes a user listening on the Ethernet interface with an AF_PACKET socket, to see different sll_protocol values for incoming and outgoing frames, because incoming frames would have this value set by parsing the Ethernet header. This patch changes the skb->protocol value for outgoing Ethernet frames, making it consistent with the Ethernet header prepended. This makes a user listening on the Ethernet device with an AF_PACKET socket, to see the same sll_protocol value for incoming and outgoing frames.
