2020-03-27scripts/dtc: Remove redundant YYLOC global declarationDirk Mueller1-1/+0
gcc 10 will default to -fno-common, which causes this error at link time: (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here This is because both dtc-lexer as well as dtc-parser define the same global symbol yyloc. Before with -fcommon those were merged into one defintion. The proper solution would be to to mark this as "extern", however that leads to: dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls] 26 | extern YYLTYPE yylloc; | ^~~~~~ In file included from dtc-lexer.l:24: dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here 127 | extern YYLTYPE yylloc; | ^~~~~~ cc1: all warnings being treated as errors which means the declaration is completely redundant and can just be dropped.

2020-03-26afs: Fix unpinned address list during probingDavid Howells1-0/+2
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.

2020-03-26KVM: X86: Narrow down the IPI fastpath to single target IPIWanpeng Li1-1/+4
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. Piccoli1-10/+41
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.

2020-03-25zonfs: Fix handling of read-only zonesDamien Le Moal2-12/+34
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 <[email protected]> Reviewed-by: Johannes Thumshirn <[email protected]>

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.

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.

2020-03-24net: cbs: Fix software cbs to consider packet sending timeZh-yuan Ye1-1/+11
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 <[email protected]> Reviewed-by: Vinicius Costa Gomes <[email protected]> Signed-off-by: David S.

2020-03-24RDMA/core: Ensure security pkey modify is not lostMike Marciniszyn1-8/+3
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.
