[Bug 1889943] Re: Improper TCP/IP packet splitting on e1000e/vmxnet3

After stepping through the code, it has become clear that the e1000e/vmxnet3 emulated models do not implement TCP segmentation, however they still "advertise" it as a feature to the guest OS. Regarding my prior interpretation, the implementation is written to forward the entire packet to the host

[PATCH] seabios-hppa: add -fno-ipa-sra to the compiler flags

Date: Wed, 22 Jul 2020 22:15:46 +0300 This allows seabios-hppa to build with gcc-10. Or else the compiler generates eg memset.isra.0 symbols instead of memset, and the final link step fails due to missing memset. Previous versions of gcc, for quite some time already, recognizes this option but it

[PATCH v2] hw/net/net_tx_pkt: fix assertion failure in net_tx_pkt_add_raw_fragment()

An assertion failure issue was found in the code that processes network packets while adding data fragments into the packet context. It could be abused by a malicious guest to abort the QEMU process on the host. This patch replaces the affected assert() with a conditional statement, returning false

[PATCH v2 3/4] hw/hppa: Implement proper SeaBIOS version check

It's important that the SeaBIOS hppa firmware is at least at a minimal level to ensure proper interaction between qemu and firmware. Implement a proper firmware version check by telling SeaBIOS via the fw_cfg interface which minimal SeaBIOS version is required by this running qemu instance. If the
