* hw/net: fsl_etsec: Reverse the RCTRL.RSF logicBin Meng2021-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per MPC8548ERM [1] chapter 14.5.3.4.1: When RCTRL.RSF is 1, frames less than 64 bytes are accepted upon a DA match. But currently QEMU does the opposite. This commit reverses the RCTRL.RSF testing logic to match the manual. Due to the reverse of the logic, certain guests may potentially break if they don't program eTSEC to have RCTRL.RSF bit set. When RCTRL.RSF is 0, short frames are silently dropped, however as of today both slirp and tap networking do not pad short frames (e.g.: an ARP packet) to the minimum frame size of 60 bytes. So ARP requests will be dropped, preventing the guest from becoming visible on the network. The same issue was reported on e1000 and vmxenet3 before, see: commit 78aeb23eded2 ("e1000: Pad short frames to minimum size (60 bytes)") commit 40a87c6c9b11 ("vmxnet3: Pad short frames to minimum size (60 bytes)") [1] https://www.nxp.com/docs/en/reference-manual/MPC8548ERM.pdf Fixes: eb1e7c3e5146 ("Add Enhanced Three-Speed Ethernet Controller (eTSEC)") Signed-off-by: Bin Meng <bin.meng@windriver.com> Message-Id: <1612923021-19746-1-git-send-email-bmeng.cn@gmail.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* net: checksum: Introduce fine control over checksum typeBin Meng2021-01-251-9/+9
| | | | | | | | | | | | | | 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>

* ptimer: Rename ptimer_init() to ptimer_init_with_bh()Peter Maydell2019-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the ptimer design uses a QEMU bottom-half as its mechanism for calling back into the device model using the ptimer when the timer has expired. Unfortunately this design is fatally flawed, because it means that there is a lag between the ptimer updating its own state and the device callback function updating device state, and guest accesses to device registers between the two can return inconsistent device state. We want to replace the bottom-half design with one where the guest device's callback is called either immediately (when the ptimer triggers by timeout) or when the device model code closes a transaction-begin/end section (when the ptimer triggers because the device model changed the ptimer's count value or other state). As the first step, rename ptimer_init() to ptimer_init_with_bh(), to free up the ptimer_init() name for the new API. We can then convert all the ptimer users away from ptimer_init_with_bh() before removing it entirely. (Commit created with git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/' and three overlong lines folded by hand.)

* sysbus: Set user_creatable=false by default on TYPE_SYS_BUS_DEVICEEduardo Habkost2017-05-171-0/+2

To fix this, we can set user_creatable=false by default on TYPE_SYS_BUS_DEVICE, but this requires setting user_creatable=true explicitly on the sysbus devices that actually work with -device. Fortunately today we have just a few has_dynamic_sysbus=1 machines: virt, pc-q35-*, ppce500, and spapr. virt, ppce500, and spapr have extra checks to ensure just a few device types can be instantiated: * virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE. * ppce500 supports only TYPE_ETSEC_COMMON. * spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE. This patch sets user_creatable=true explicitly on those 4 device classes. Now, the more complex cases: pc-q35-*: q35 has no sysbus device whitelist yet (which is a separate bug). We are in the process of fixing it and building a sysbus whitelist on q35, but in the meantime we can fix the "-device help" and "info qdm" bugs mentioned above. Also, despite not being strictly necessary for fixing the q35 bug, reducing the list of user_creatable=true devices will help us be more confident when building the q35 whitelist. xen: We also have a hack at xen_set_dynamic_sysbus(), that sets has_dynamic_sysbus=true at runtime when using the Xen accelerator. This hack is only used to allow xen-backend devices to be dynamically plugged/unplugged. This means today we can use -device with the following 22 device types, that are the ones compiled into the qemu-system-x86_64 and qemu-system-i386 binaries: * allwinner-ahci * amd-iommu * cfi.pflash01 * esp * fw_cfg_io * fw_cfg_mem * generic-sdhci * hpet * intel-iommu * ioapic * isabus-bridge * kvmclock * kvm-ioapic * kvmvapic * SUNW,fdtwo * sysbus-ahci * sysbus-fdc * sysbus-ohci * unimplemented-device * virtio-mmio * xen-backend * xen-sysdev This patch adds user_creatable=true explicitly to those devices, temporarily, just to keep 100% compatibility with existing behavior of q35. Subsequent patches will remove user_creatable=true from the devices that are really not meant to user-creatable on any machine, and remove the FIXME comment from the ones that are really supposed to be user-creatable.

* trace: switch to modular code generation for sub-directoriesDaniel P. Berrange2017-01-311-1/+0Star
| | | | | | | | | | | | | | | Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir.

* fsl_etsec: Fix Tx BD ring wrapping handlingAndrey Smirnov2017-01-061-10/+9Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code that handles Tx buffer desciprtor ring scanning employs the following algorithm: 1. Restore current buffer descriptor pointer from TBPTRn 2. Process current descriptor 3. If current descriptor has BD_WRAP flag set set current descriptor pointer to start of the descriptor ring 4. If current descriptor points to start of the ring exit the loop, otherwise increment current descriptor pointer and go to #2 5. Store current descriptor in TBPTRn The way the code is implemented results in buffer descriptor ring being scanned starting at offset/descriptor #0. While covering 99% of the cases, this algorithm becomes problematic for a number of edge cases. Consider the following scenario: guest OS driver initializes descriptor ring to N individual descriptors and starts sending data out. Depending on the volume of traffic and probably guest OS driver implementation it is possible that an edge case where a packet, spread across 2 descriptors is placed in descriptors N - 1 and 0 in that order(it is easy to imagine similar examples involving more than 2 descriptors). What happens then is aforementioned algorithm starts at descriptor 0, sees a descriptor marked as BD_LAST, which it happily sends out as a separate packet(very much malformed at this point) then the iteration continues and the first part of the original packet is tacked to the next transmission which ends up being bogus as well. This behvaiour can be pretty reliably observed when scp'ing data from a guest OS via TAP interface for files larger than 160K (every time for 700K+). This patch changes the scanning algorithm to do the following: 1. Restore "current" buffer descriptor pointer from TBPTRn 2. If "current" descriptor does not have BD_TX_READY set, goto #6 3. Process current descriptor 4. If "current" descriptor has BD_WRAP flag set "current" descriptor pointer to start of the descriptor ring otherwise set increment "current" by the size of one descriptor 5. Goto #1 6. Save "current" buffer descriptor in TBPTRn This way we preserve the information about which descriptor was processed last and always start where we left off avoiding the original problem. On top of that, judging by the following excerpt from MPC8548ERM (p. 14-48): "... When the end of the TxBD ring is reached, eTSEC initializes TBPTRn to the value in the corresponding TBASEn. The TBPTR register is internally written by the eTSEC’s DMA controller during transmission. The pointer increments by eight (bytes) each time a descriptor is closed successfully by the eTSEC..." revised algorithm might also a more correct way of emulating this aspect of eTSEC peripheral.

* fsl_etsec: Pad short payloads with zerosAndrey Smirnov2016-12-051-0/+8
| | | | | | | | | | | | | | | | Depending on QEMU network setup it is possible for us to receive a complete Ethernet packet that is less 64 bytes long. One such example is when QEMU is configured to use a standalone TAP device (not set to be a part of any bridge) receives and ARP packet. In cases like that we need to add more than just 4-bytes of CRC padding and ensure that our payload is at least 60 bytes long, such that, when combined with CRC padding bytes the resulting size is at least 802.3 minimum MTU bytes long (64). Failing to do that results in code in etsec_walk_rx_ring() setting BD_RX_SH which, in turn, makes corresponding Linux driver of emulated host to reject buffer as a runt packet Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

* qapi: Change Netdev into a flat unionEric Blake2016-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.

* net: remove all cleanup methods from NIC NetClientInfosPaolo Bonzini2015-01-121-6/+0Star
| | | | | | | | | | | | | | | | | All NICs have a cleanup function that, in most cases, zeroes the pointer to the NICState. In some cases, it frees data belonging to the NIC. However, this function is never called except when exiting from QEMU. It is not necessary to NULL pointers and free data here; the right place to do that would be in the device's unrealize function, after calling qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue devices. This cleanup function gets in the way of making the NetClientStates for the NIC hold an object_ref reference to the object, so get rid of it.
