2021-08-27mptcp: optimize the input options processingPaolo Abeni1-34/+37
Most MPTCP packets carries a single MPTCP subption: the DSS containing the mapping for the current packet. Check explicitly for the above, so that is such scenario we replace most conditional statements with a single likely() one.

2021-08-27mptcp: better binary layout for mptcp_options_receivedPaolo Abeni2-15/+13
This change reorder the mptcp_options_received fields to shrink the structure a bit and to ensure the most frequently used fields are all in the first cacheline. Sub-opt specific flags are moved out of the suboptions area, and we must now explicitly set them when the relevant suboption is parsed. There is a notable exception: 'csum_reqd' is used by both DSS and MPC suboptions, and keeping such field in the suboptions flag area will simplfy the next patch.

2021-08-27net: don't unconditionally copy_from_user a struct ifreq for socket ioctlsPeter Collingbourne2-1/+9
A common implementation of isatty(3) involves calling a ioctl passing a dummy struct argument and checking whether the syscall failed -- bionic and glibc use TCGETS (passing a struct termios), and musl uses TIOCGWINSZ (passing a struct winsize). If the FD is a socket, we will copy sizeof(struct ifreq) bytes of data from the argument and return -EFAULT if that fails. The result is that the isatty implementations may return a non-POSIX-compliant value in errno in the case where part of the dummy struct argument is inaccessible, as both struct termios and struct winsize are smaller than struct ifreq (at least on arm64). Although there is usually enough stack space following the argument on the stack that this did not present a practical problem up to now, with MTE stack instrumentation it's more likely for the copy to fail, as the memory following the struct may have a different tag. Fix the problem by adding an early check for whether the ioctl is a valid socket ioctl, and return -ENOTTY if it isn't.

2021-08-27crypto: sha512 - remove imaginary and mystifying clearing of variablesLukas Bulwahn1-3/+0
The function sha512_transform() assigns all local variables to 0 before returning to its caller with the intent to erase sensitive data. However, make clang-analyzer warns that all these assignments are dead stores, and as commit 7a4295f6c9d5 ("crypto: lib/sha256 - Don't clear temporary variables") already points out for sha256_transform(): The assignments to clear a through h and t1/t2 are optimized out by the compiler because they are unused after the assignments. Clearing individual scalar variables is unlikely to be useful, as they may have been assigned to registers, and even if stack spilling was required, there may be compiler-generated temporaries that are impossible to clear in any case. This applies here again as well. Drop meaningless clearing of local variables and avoid this way that the code suggests that data is erased, which simply does not happen.

2021-08-27crypto: x86/sm4 - add AES-NI/AVX2/x86_64 implementationTianjia Zhang4-0/+691
Like the implementation of AESNI/AVX, this patch adds an accelerated implementation of AESNI/AVX2. In terms of code implementation, by reusing AESNI/AVX mode-related codes, the amount of code is greatly reduced. From the benchmark data, it can be seen that when the block size is 1024, compared to AVX acceleration, the performance achieved by AVX2 has increased by about 70%, it is also 7.7 times of the pure software implementation of sm4-generic. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. Benchmark on Intel i5-6200U 2.30GHz, performance data of three implementation methods, pure software sm4-generic, aesni/avx acceleration, and aesni/avx2 acceleration, the data comes from the 218 mode and 518 mode of tcrypt. The abscissas are blocks of different lengths.

To track each STE of the rule a rule member was allocated, each member would point to one STE. This means that we would allocate 40B (rule member) * number of STEs per rule. To reduce this per rule allocation we use the STE tree pointers for next_htbl and pointing STE to navigate the tree, this allows us to keep only the pointer to the last STE of rule (always unique). From the last rule STE we are able to traverse and rebuild all of the STEs that construct the rule. In our testing with 8M rules, each consisting of 7 STES, we were able to reduce 1.6GB of memory.

2021-08-26net/mlx5: DR, Enable QP retransmissionYevgeny Kliteynik1-0/+1
Under high stress, SW steering might get stuck on polling for completion that never comes. For such cases QP needs to have protocol retransmission mechanism enabled. Currently the retransmission timeout is defined as 0 (unlimited). Fix this by defining a real timeout.

2021-08-26net/mlx5: DR, Enable VLAN pop on TX and VLAN push on RXYevgeny Kliteynik3-9/+118
Enable pop VLAN action in TX and push VLAN in RX. These actions are supported only on STEv1. On TX: when a host sends a packet, VLAN is popped at the beginning. On RX: just before passing the packet to the host the VLAN is pushed.

ConnectX supports offloading of various encapsulations and decapsulations (e.g. VXLAN), which are performed by 'Packet Reformat' action. Starting with ConnectX-6 DX, a new reformat type is supported - REMOVE_HEADER, which allows deleting an arbitrary size chunk at the selected position in the packet.

2021-08-27PCI/MSI: Skip masking MSI-X on Xen PVMarek Marczykowski-Górecki1-0/+3
When running as Xen PV guest, masking MSI-X is a responsibility of the hypervisor. The guest has no write access to the relevant BAR at all - when it tries to, it results in a crash like this: BUG: unable to handle page fault for address: ffffc9004069100c #PF: supervisor write access in kernel mode #PF: error_code(0x0003) - permissions violation RIP: e030:__pci_enable_msix_range.part.0+0x26b/0x5f0 e1000e_set_interrupt_capability+0xbf/0xd0 [e1000e] e1000_probe+0x41f/0xdb0 [e1000e] local_pci_probe+0x42/0x80 (...) The recently introduced function msix_mask_all() does not check the global variable pci_msi_ignore_mask which is set by XEN PV to bypass the masking of MSI[-X] interrupts. Add the check to make this function XEN PV compatible.

In line 849 (#1), "mlx5dr_htbl_put(cur_htbl);" drops the reference to cur_htbl and may cause cur_htbl to be freed. However, cur_htbl is subsequently used in the next line, which may result in an use-after-free bug. Fix this by calling mlx5dr_err() before the cur_htbl is put.

2021-08-26net/mlx5e: Use correct eswitch for stack devices with lagDmytro Linkin1-0/+18
If link aggregation is used within stack devices driver rejects encap rules if PF of the VF tunnel device is down. This happens because route resolved for other PF and its eswitch instance is used to determine correct vport. To fix that use devcom feature to retrieve other eswitch instance if failed to find vport for the 1st eswitch and LAG is active.
