When it's probing all of a fileserver's interfaces to find which one is best to use, afs_do_probe_fileserver() takes a lock on the server record and notes the pointer to the address list. It doesn't, however, pin the address list, so as soon as it drops the lock, there's nothing to stop the address list from being freed under us. Fix this by taking a ref on the address list inside the locked section and dropping it at the end of the function.

Testing 'parse-maintainers' due to the previous commit shows a bad file pattern for the "TI VPE/CAL DRIVERS" entry in the MAINTAINERS file. There's also a lot of mis-ordered entries, but I'm still a bit nervous about the inevitable and annoying merge problems it would probably cause to fix them up. The MAINTAINERS file is one of my least favorite files due to being huge and centralized, but fixing it is also horribly painful for that reason.

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).

Guilherme G. Piccoli authored
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.

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>

This test covers two recent fixes: 07f8e4d0 ("tcp: also NULL skb->dev when copy was needed") and b738a185 ("tcp: ensure skb->dev is NULL before leaving TCP stack"). 2) The fwd action breaks with ifb. For safety in next extensions, make sure the fwd action only runs from ingress until it is extended to be used from a different hook. 3) The pipapo set type now reports EEXIST in case of subrange overlaps. Update the rbtree set to validate range overlaps, so far this validation is only done only from userspace. From Stefano Brivio. ==================== Signed-off-by: David S.

Saeed Mahameed says: ==================== Mellanox, mlx5 fixes 2020-03-24 This series introduces some fixes to mlx5 driver. From Aya, Fixes to the RX error recovery flows From Leon, Fix IB capability mask Please pull and let me know if there is any problem. For -stable v5.5 ('net/mlx5_core: Set IB capability mask1 to fix ib_srpt connection failure') For -stable v5.4 ('net/mlx5e: Fix ICOSQ recovery flow with Striding RQ') ('net/mlx5e: Do not recover from a non-fatal syndrome') ('net/mlx5e: Fix missing reset of SW metadata in Striding RQ reset') ('net/mlx5e: Enhance ICOSQ WQE info fields') The above patch ('net/mlx5e: Enhance ICOSQ WQE info fields') will fail to apply cleanly on v5.4 due to a trivial contextual conflict, but it is an important fix, do I need to do something about it or just assume Greg will know how to handle this ? ==================== Signed-off-by: David S.

The original change fixed an issue on RTL8168b by mimicking the vendor driver behavior to disable MSI on chip versions before RTL8168d. This however now caused an issue on a system with RTL8168c, see [0]. Therefore leave MSI disabled on RTL8168b, but re-enable it on RTL8168c.

The DT binding for this PHY describes an *optional* clock property. Due to a bug in the error handling logic, we are actually ignoring this clock *all* of the time so far. Fix this by using devm_clk_get_optional() to handle this clock properly.

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: 585d763a ("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.

The commit 19ba1eb1 ("Input: psmouse - add a custom serio protocol to send extra information") introduced usage of the BIT() macro for SERIO_* flags; this macro is not provided in UAPI headers.
