Since it's not used beyond the function scope, this switches to using a stack variable instead.

2c88c74	Ard Biesheuvel	18 January 2019, 10:58:07 UTC	gcc-plugins: arm_ssp_per_task_plugin: fix for GCC 9+ GCC 9 reworks the way the references to the stack canary are emitted, to prevent the value from being spilled to the stack before the final comparison in the epilogue, defeating the purpose, given that the spill slot is under control of the attacker that we are protecting ourselves from. Since our canary value address is obtained without accessing memory (as opposed to pre-v7 code that will obtain it from a literal pool), it is unlikely (although not guaranteed) that the compiler will spill the canary value in the same way, so let's just disable this improvement when building with GCC9+.

fbfaf85	Florian La Roche	19 January 2019, 15:14:50 UTC	fix int_sqrt64() for very large numbers If an input number x for int_sqrt64() has the highest bit set, then fls64(x) is 64. (1UL << 64) is an overflow and breaks the algorithm. Subtracting 1 is a better guess for the initial value of m anyway and that's what also done in int_sqrt() implicitly []. [] Note how int_sqrt() uses __fls() with two underscores, which already returns the proper raw bit number. In contrast, int_sqrt64() used fls64(), and that returns bit numbers illogically starting at 1, because of error handling for the "no bits set" case. Will points out that he bug probably is due to a copy-and-paste error from the regular int_sqrt() case.

6e693b3	Will Deacon	19 January 2019, 21:56:05 UTC	x86: uaccess: Inhibit speculation past access_ok() in user_access_begin() Commit 594cc251fdd0 ("make 'user_access_begin()' do 'access_ok()'") makes the access_ok() check part of the user_access_begin() preceding a series of 'unsafe' accesses. This has the desirable effect of ensuring that all 'unsafe' accesses have been range-checked, without having to pick through all of the callsites to verify whether the appropriate checking has been made. However, the consolidated range check does not inhibit speculation, so it is still up to the caller to ensure that they are not susceptible to any speculative side-channel attacks for user addresses that ultimately fail the access_ok() check. This is an oversight, so use __uaccess_begin_nospec() to ensure that speculation is inhibited until the access_ok() check has passed.

Redirecting to a sit0 through __bpf_redirect_no_mac pulls the mac length, even though skb->data already is at skb->network_header. bpf_prog_test_run_skb has already pulled it as LWT_XMIT !is_l2. Update the offset calculation to pull only if skb->data differs from skb->network_header, which is not true in this case. The test itself can be run only from commit 1cf1cae963c2 ("bpf: introduce BPF_PROG_TEST_RUN command"), but the same type of packets with skb at network header could already be built from lwt xmit hooks, so this fix is more relevant to that commit. Also set the mac header on redirect from LWT_XMIT, as even after this change to __bpf_redirect_no_mac that field is expected to be set, but is not yet in ip_finish_output2.

25f2d0e	Eli Britstein	19 December 2018, 05:36:51 UTC	net/mlx5e: Fix cb_ident duplicate in indirect block register Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the tunnel netdev we were interested in receiving updates on. This worked fine if a single PF existed that registered one callback for the tunnel netdev of interest. However, if multiple PFs are in place then the 2nd PF tries to register with the same tunnel netdev identifier. This leads to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the rpriv pointer as the identifier for netdev indirect block cb registry, allowing each PF to register a unique callback per tunnel netdev. For block cb registry, the same PF may register multiple cbs to the same block if using TC shared blocks. Instead of the rpriv, use the pointer to the allocated indr_priv data as the identifier here. This means that there can be a unique block callback for each PF/tunnel netdev combo.

e8c8b53	Cong Wang	04 December 2018, 06:14:04 UTC	net/mlx5e: Force CHECKSUM_UNNECESSARY for short ethernet frames When an ethernet frame is padded to meet the minimum ethernet frame size, the padding octets are not covered by the hardware checksum. Fortunately the padding octets are usually zero's, which don't affect checksum. However, we have a switch which pads non-zero octets, this causes kernel hardware checksum fault repeatedly. Prior to: commit '88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE ...")' skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, we need to keep skb->csum updated, like what we do for RXFCS. However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP headers, it is not worthy the effort as the packets are so small that CHECKSUM_COMPLETE can't save anything.

9d5564d	Daniel Borkmann	17 January 2019, 15:34:45 UTC	bpf: fix inner map masking to prevent oob under speculation During review I noticed that inner meta map setup for map in map is buggy in that it does not propagate all needed data from the reference map which the verifier is later accessing. In particular one such case is index masking to prevent out of bounds access under speculative execution due to missing the map's unpriv_array/index_mask field propagation.

a11dcd6	Nir Dotan	18 January 2019, 15:57:59 UTC	mlxsw: spectrum_fid: Update dummy FID index When using a tc flower action of egress mirred redirect, the driver adds an implicit FID setting action. This implicit action sets a dummy FID to the packet and is used as part of a design for trapping unmatched flows in OVS. While this implicit FID setting action is supposed to be a NOP when a redirect action is added, in Spectrum-2 the FID record is consulted as the dummy FID index is an 802.1D FID index and the packet is dropped instead of being redirected. Set the dummy FID index value to be within 802.1Q range. This satisfies both Spectrum-1 which ignores the FID and Spectrum-2 which identifies it as an 802.1Q FID and will then follow the redirect action.

c9ebea0	Ido Schimmel	18 January 2019, 15:57:55 UTC	mlxsw: pci: Ring CQ's doorbell before RDQ's When a packet should be trapped to the CPU the device consumes a WQE (work queue element) from an RDQ (receive descriptor queue) and copies the packet to the address specified in the WQE. The device then tries to post a CQE (completion queue element) that contains various metadata (e.g., ingress port) about the packet to a CQ (completion queue). In case the device managed to consume a WQE, but did not manage to post the corresponding CQE, it will get stuck. This unlikely situation can be triggered due to the scheme the driver is currently using to process CQEs. The driver will consume up to 512 CQEs at a time and after processing each corresponding WQE it will ring the RDQ's doorbell, letting the device know that a new WQE was posted for it to consume. Only after processing all the CQEs (up to 512), the driver will ring the CQ's doorbell, letting the device know that new ones can be posted. Fix this by having the driver ring the CQ's doorbell for every processed CQE, but before ringing the RDQ's doorbell. This guarantees that whenever we post a new WQE, there is a corresponding CQE available. Copy the currently processed CQE to prevent the device from overwriting it with a new CQE after ringing the doorbell. Note that the driver still arms the CQ only after processing all the pending CQEs, so that interrupts for this CQ will only be delivered after the driver finished its processing. Before commit 8404f6f2e8ed ("mlxsw: pci: Allow to use CQEs of version 1 and version 2") the issue was virtually impossible to trigger since the number of CQEs was twice the number of WQEs and the number of CQEs processed at a time was equal to the number of available WQEs.

fd340d0	Josef Bacik	11 January 2019, 15:21:02 UTC	btrfs: wakeup cleaner thread when adding delayed iput The cleaner thread usually takes care of delayed iputs, with the exception of the btrfs_end_transaction_throttle path. Delaying iputs means we are potentially delaying the eviction of an inode and it's respective space. The cleaner thread only gets woken up every 30 seconds, or when we require space. If there are a lot of inodes that need to be deleted we could induce a serious amount of latency while we wait for these inodes to be evicted. So instead wakeup the cleaner if it's not already awake to process any new delayed iputs we add to the list. If we suddenly need space we will less likely be backed up behind a bunch of inodes that are waiting to be deleted, and we could possibly free space before we need to get into the flushing logic which will save us some latency.

So before we decide to commit the transaction for ENOPSC reasons, run the delayed iputs so that any potential space is free'd up. If there is and we freed enough we can then commit the transaction and potentially be able to make our reservation.

5ab3121	Lendacky, Thomas	17 January 2019, 14:20:14 UTC	amd-xgbe: Fix mdio access for non-zero ports and clause 45 PHYs The XGBE hardware has support for performing MDIO operations using an MDIO command request. The driver mistakenly uses the mdio port address as the MDIO command request device address instead of the MDIO command request port address. Additionally, the driver does not properly check for and create a clause 45 MDIO command. Check the supplied MDIO register to determine if the request is a clause 45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device address and register number from the supplied MDIO register and use them to set the MDIO command request device address and register number fields. For a clause 22 operation, the MDIO request device address is set to zero and the MDIO command request register number is set to the supplied MDIO register. In either case, the supplied MDIO port address is used as the MDIO command request port address.

Because the ethernet header length has been considered in is_skb_forwardable(including dev->hard_header_len length). To reproduce the issue: 1, add 2 ports on linux bridge br using following commands: $ brctl addbr br $ brctl addif br eth0 $ brctl addif br eth1 2, the MTU of eth0 and eth1 is 1500 3, send a packet(Data 1480, UDP 8, IP 20, Ethernet 14, VLAN 4) from eth0 to eth1 So the expect result is packet larger than 1500 cannot pass through eth0 and eth1. But currently, the packet passes through success, it means eth1's MTU limit doesn't take effect.

cc5e710	Jason Wang	16 January 2019, 08:54:42 UTC	vhost: log dirty page correctly Vhost dirty page logging API is designed to sync through GPA. But we try to log GIOVA when device IOTLB is enabled. This is wrong and may lead to missing data after migration. To solve this issue, when logging with device IOTLB enabled, we will: 1) reuse the device IOTLB translation result of GIOVA->HVA mapping to get HVA, for writable descriptor, get HVA through iovec. For used ring update, translate its GIOVA to HVA 2) traverse the GPA->HVA mapping to get the possible GPA and log through GPA. Pay attention this reverse mapping is not guaranteed to be unique, so we should log each possible GPA in this case. This fix the failure of scp to guest during migration. In -next, we will probably support passing GIOVA->GPA instead of GIOVA->HVA.

This problem is more generally related to device with variable hard header length. To avoid a too intrusive patch in the current release, a (ugly) workaround is proposed in this patch. It has to be cleaned up in net-next.
