2020-03-26mac80211: mark station unauthorized before key removalJohannes Berg
If a station is still marked as authorized, mark it as no longer so before removing its keys. This allows frames transmitted to it to be rejected, providing additional protection against leaking plain text data during the disconnection flow.

2020-03-26mac80211: Check port authorization in the ieee80211_tx_dequeue() caseJouni Malinen
mac80211 used to check port authorization in the Data frame enqueue case when going through start_xmit(). However, that authorization status may change while the frame is waiting in a queue. Add a similar check in the dequeue case to avoid sending previously accepted frames after authorization change. This provides additional protection against potential leaking of frames after a station has been disconnected and the keys for it are being removed.

2020-03-26cfg80211: Do not warn on same channel at the end of CSAIlan Peer
When cfg80211_update_assoc_bss_entry() is called, there is a verification that the BSS channel actually changed. As some APs use CSA also for bandwidth changes, this would result with a kernel warning. Fix this by removing the WARN_ON().

2020-03-26mac80211: drop data frames without key on encrypted linksJohannes Berg
If we know that we have an encrypted link (based on having had a key configured for TX in the past) then drop all data frames in the key selection handler if there's no key anymore. This fixes an issue with mac80211 internal TXQs - there we can buffer frames for an encrypted link, but then if the key is no longer there when they're dequeued, the frames are sent without encryption. This happens if a station is disconnected while the frames are still on the TXQ. Detecting that a link should be encrypted based on a first key having been configured for TX is fine as there are no use cases for a connection going from with encryption to no encryption. With extended key IDs, however, there is a case of having a key configured for only decryption, so we can't just trigger this behaviour on a key being configured.

2020-03-26KVM: X86: Narrow down the IPI fastpath to single target IPIWanpeng Li
The original single target IPI fastpath patch forgot to filter the ICR destination shorthand field. Multicast IPI is not suitable for this feature since wakeup the multiple sleeping vCPUs will extend the interrupt disabled time, it especially worse in the over-subscribe and VM has a little bit more vCPUs scenario. Let's narrow it down to single target IPI. Two VMs, each is 76 vCPUs, one running 'ebizzy -M', the other running cyclictest on all vCPUs, w/ this patch, the avg score of cyclictest can improve more than 5%. (pv tlb, pv ipi, pv sched yield are disabled during testing to avoid the disturb).

2020-03-25net: ena: Add PCI shutdown handler to allow safe kexecGuilherme G. Piccoli
Currently ENA only provides the PCI remove() handler, used during rmmod for example. This is not called on shutdown/kexec path; we are potentially creating a failure scenario on kexec: (a) Kexec is triggered, no shutdown() / remove() handler is called for ENA; instead pci_device_shutdown() clears the master bit of the PCI device, stopping all DMA transactions; (b) Kexec reboot happens and the device gets enabled again, likely having its FW with that DMA transaction buffered; then it may trigger the (now invalid) memory operation in the new kernel, corrupting kernel memory area. This patch aims to prevent this, by implementing a shutdown() handler quite similar to the remove() one - the difference being the handling of the netdev, which is unregistered on remove(), but following the convention observed in other drivers, it's only detached on shutdown(). This prevents an odd issue in AWS Nitro instances, in which after the 2nd kexec the next one will fail with an initrd corruption, caused by a wild DMA write to invalid kernel memory.

2020-03-24scsi: sd: Fix optimal I/O size for devices that change reported valuesMartin K. Petersen
Some USB bridge devices will return a default set of characteristics during initialization. And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.

2020-03-25zonfs: Fix handling of read-only zonesDamien Le Moal
The write pointer of zones in the read-only consition is defined as invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not possible to determine the correct size of a read-only zone file on mount. Fix this by handling read-only zones in the same manner as offline zones by disabling all accesses to the zone (read and write) and initializing the inode size of the read-only zone to 0). For zones found to be in the read-only condition at runtime, only disable write access to the zone and keep the size of the zone file to its last updated value to allow the user to recover previously written data. Also fix zonefs documentation file to reflect this change. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com>

Not only did this wheel did not need reinventing, but there is also an issue with it: It doesn't remove the VLAN header in a way that preserves the L2 payload checksum when that is being provided by the DSA master hw. It should recalculate checksum both for the push, before removing the header, and for the pull afterwards. But the current implementation is quite dizzying, with pulls followed immediately afterwards by pushes, the memmove is done before the push, etc. This makes a DSA master with RX checksumming offload to print stack traces with the infamous 'hw csum failure' message. So remove the dsa_8021q_remove_header function and replace it with something that actually works with inet checksumming.

Currently the software CBS does not consider the packet sending time when depleting the credits. It caused the throughput to be Idleslope[kbps] * (Port transmit rate[kbps] / |Sendslope[kbps]|) where Idleslope * (Port transmit rate / (Idleslope + |Sendslope|)) = Idleslope is expected. In order to fix the issue above, this patch takes the time when the packet sending completes into account by moving the anchor time variable "last" ahead to the send completion time upon transmission and adding wait when the next dequeue request comes before the send completion time of the previous packet. changelog: V2->V3: - remove unnecessary whitespace cleanup - add the checks if port_rate is 0 before division V1->V2: - combine variable "send_completed" into "last" - add the comment for estimate of the packet sending Fixes: 585d763af09c ("net/sched: Introduce Credit Based Shaper (CBS) qdisc") Signed-off-by: Zh-yuan Ye <ye.zh-yuan@socionext.com> Reviewed-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Signed-off-by: David S.

2020-03-24RDMA/core: Ensure security pkey modify is not lostMike Marciniszyn
The following modify sequence (loosely based on ipoib) will lose a pkey modifcation: - Modify (pkey index, port) - Modify (new pkey index, NO port) After the first modify, the qp_pps list will have saved the pkey and the unit on the main list. During the second modify, get_new_pps() will fetch the port from qp_pps and read the new pkey index from qp_attr->pkey_index. The state will still be zero, or IB_PORT_PKEY_NOT_VALID. Because of the invalid state, the new values will never replace the one in the qp pps list, losing the new pkey. This happens because the following if statements will never correct the state because the first term will be false. If the code had been executed, it would incorrectly overwrite valid values. if ((qp_attr_mask & IB_QP_PKEY_INDEX) && (qp_attr_mask & IB_QP_PORT)) new_pps->main.state = IB_PORT_PKEY_VALID; if (!(qp_attr_mask & (IB_QP_PKEY_INDEX | IB_QP_PORT)) && qp_pps) { new_pps->main.port_num = qp_pps->main.port_num; new_pps->main.pkey_index = qp_pps->main.pkey_index; if (qp_pps->main.state != IB_PORT_PKEY_NOT_VALID) new_pps->main.state = IB_PORT_PKEY_VALID; } Fix by joining the two if statements with an or test to see if qp_pps is non-NULL and in the correct state.
