2021-01-25net: checksum: Introduce fine control over checksum typeBin Meng
At present net_checksum_calculate() blindly calculates all types of checksums (IP, TCP, UDP). Some NICs may have a per type setting in their BDs to control what checksum should be offloaded. To support such hardware behavior, introduce a 'csum_flag' parameter to the net_checksum_calculate() API to allow fine control over what type checksum is calculated. Existing users of this API are updated accordingly. Signed-off-by: Bin Meng <bin.meng@windriver.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2021-01-12hw/net/lan9118: Add symbolic constants for register offsetsPeter Maydell
The lan9118 code mostly uses symbolic constants for register offsets; the exceptions are those which the datasheet doesn't give an official symbolic name to. Add some names for the registers which don't already have them, based on the longer names they are given in the memory map.

2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-11-11hw/net/can/ctucan_core: Handle big-endian hostsPeter Maydell
The ctucan driver defines types for its registers which are a union of a uint32_t with a struct with bitfields for the individual fields within that register. This is a bad idea, because bitfields aren't portable. The ctu_can_fd_regs.h header works around the most glaring of the portability issues by defining the fields in two different orders depending on the setting of the __LITTLE_ENDIAN_BITFIELD define. However, in ctucan_core.h this is unconditionally set to 1, which is wrong for big-endian hosts. Set it only if HOST_WORDS_BIGENDIAN is not set. There is no need for a "have we defined it already" guard, because the only place that should set it is ctucan_core.h, which has the usual double-inclusion guard.

2020-11-11hw/net/can/ctucan: Avoid unused value in ctucan_send_ready_buffers()Peter Maydell
Coverity points out that in ctucan_send_ready_buffers() we set buff_st_mask = 0xf << (i * 4) inside the loop, but then we never use it before overwriting it later. The only thing we use the mask for is as part of the code that is inserting the new buff_st field into tx_status. That is more comprehensibly written using deposit32(), so do that and drop the mask variable entirely. We also update the buff_st local variable at multiple points during this function, but nothing can ever see these intermediate values, so just drop those, write the final TXT_TOK as a fixed constant value, and collapse the only remaining set/use of buff_st down into an extract32().

2020-11-11hw/net/can/ctucan: Don't allow guest to write off end of tx_bufferPeter Maydell
The ctucan device has 4 CAN bus cores, each of which has a set of 20 32-bit registers for writing the transmitted data. The registers are however not contiguous; each core's buffers is 0x100 bytes after the last. We got the checks on the address wrong in the ctucan_mem_write() function: * the first "is addr in range at all" check allowed addr == CTUCAN_CORE_MEM_SIZE, which is actually the first byte off the end of the range * the decode of addresses into core-number plus offset in the tx buffer for that core failed to check that the offset was in range, so the guest could write off the end of the tx_buffer[] array NB: currently the values of CTUCAN_CORE_MEM_SIZE, CTUCAN_CORE_TXBUF_NUM, etc, make "buff_num >= CTUCAN_CORE_TXBUF_NUM" impossible, but we retain this as a runtime check rather than an assertion to permit those values to be changed in future (in hardware they are configurable synthesis parameters). Fix the top level check, and check the offset is within the buffer.

2020-10-28hw/net: move allocation to the heap due to very large stack frameElena Afanasova
[dwg] The stack frame itself probably isn't that big a deal, but avoiding alloca() is generally recommended these days.

2020-10-12qdev: add "check if address free" callback for busesPaolo Bonzini
Check if an address is free on the bus before plugging in the device. This makes it possible to do the check without any side effects, and to detect the problem early without having to do it in the realize callback.

2020-09-30hw/net/can: Correct Kconfig dependenciesPavel Pisa
The original CAN_PCI config option enables multiple SJA1000 PCI boards emulation build. These boards bridge SJA1000 into I/O or memory address space of the host CPU and depend on SJA1000 emulation.

2020-09-30hw/net/can: CTU CAN FD IP open hardware core emulation.Jan Charvat
The implementation of the model of complete open-source/design/hardware CAN FD controller. The IP core project has been started and is maintained by Ondrej Ille at Czech Technical University in Prague. CTU CAN FD project pages: https://gitlab.fel.cvut.cz/canbus/ctucanfd_ip_core CAN bus CTU FEE Projects Listing page: http://canbus.pages.fel.cvut.cz/ The core is mapped to PCIe card same as on one of its real hardware adaptations. The device implementing two CTU CAN FD ip cores is instantiated after CAN bus definition -object can-bus,id=canbus0-bus by QEMU parameters -device ctucan_pci,canbus0=canbus0-bus,canbus1=canbus0-bus Signed-off-by: Jan Charvat <charvj10@fel.cvut.cz> Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Message-Id: <23e3ca4dcb2cc9900991016910a6cab7686c0e31.1600069689.git.pisa@cmp.felk.cvut.cz> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-09-30hw/net/can/ctucafd: Add CTU CAN FD core register definitions.Jan Charvat
Definitions of registers and CAN FD frame message box of CTU CAN FD IP core are generated the specification in CACTUS/IP-XACT format. CTU CAN FD IP core repository https://gitlab.fel.cvut.cz/canbus/ctucanfd_ip_core The location of the CTU CAN IP core specification within IP core design spec/CTU/ip/CAN_FD_IP_Core/2.1/CAN_FD_IP_Core.2.1.xml The header files are generated by pyXact_generator designed by Ondrej Ille which is based on ipyxact_parser. The specification is source of header files for driver and emulation, documentation and VHDL registers map implementation.
