2023-05-26hw/scsi/lsi53c895a: Fix reentrancy issues in the LSI controller (CVE-2023-0330)Thomas Huth1-6/+17
We cannot use the generic reentrancy guard in the LSI code, so we have to manually prevent endless reentrancy here. The problematic lsi_execute_script() function has already a way to detect whether too many instructions have been executed - we just have to slightly change the logic here that it also takes into account if the function has been called too often in a reentrant way. The code in fuzz-lsi53c895a-test.c has been taken from an earlier patch by Mauro Matteo Cascella.

2023-05-26lsi53c895a: disable reentrancy detection for MMIO region, tooThomas Huth1-0/+1
While trying to use a SCSI disk on the LSI controller with an older version of Fedora (25), I'm getting: qemu: warning: Blocked re-entrant IO on MemoryRegion: lsi-mmio at addr: 0x34 and the SCSI controller is not usable. Seems like we have to disable the reentrancy checker for the MMIO region, too, to get this working again. The problem could be reproduced it like this: ./qemu-system-x86_64 -accel kvm -m 2G -machine q35 \ -device lsi53c810,id=lsi1 -device scsi-hd,drive=d0 \ -drive if=none,id=d0,file=.../somedisk.qcow2 \ -cdrom Fedora-Everything-netinst-i386-25-1.3.iso Where somedisk.qcow2 is an image that contains already some partitions and file systems. In the boot menu of Fedora, go to "Troubleshooting" -> "Rescue a Fedora system" -> "3) Skip to shell" Then check "dmesg | grep -i 53c" for failure messages, and try to mount a partition from somedisk.qcow2.

Add an option for hostmem-file to start the memory object at an offset into the target file. This is useful if multiple memory objects reside inside the same target file, such as a device node. In particular, it's useful to map guest memory directly into /dev/mem for experimentation. To make this work consistently, also fix up all places in QEMU that expect fd offsets to be 0.

If the driver sets large_send_mss to 0 then a divide-by-zero occurs. Even if the division wasn't a problem, the for loop that emits MSS-sized packets would never terminate. Solve these issues by skipping offloading when large_send_mss=0. This issue was found by OSS-Fuzz as part of Alexander Bulekov's device fuzzing work.

2023-05-23e1000e: Notify only new interruptsAkihiko Odaki3-88/+69
In MSI-X mode, if there are interrupts already notified but not cleared and a new interrupt arrives, e1000e incorrectly notifies the notified ones again along with the new one. To fix this issue, replace e1000e_update_interrupt_state() with two new functions: e1000e_raise_interrupts() and e1000e_lower_interrupts(). These functions don't only raise or lower interrupts, but it also performs register writes which updates the interrupt state. Before it performs a register write, these function determines the interrupts already raised, and compares with the interrupts raised after the register write to determine the interrupts to notify. The introduction of these functions made tracepoints which assumes that the caller of e1000e_update_interrupt_state() performs register writes obsolete. These tracepoints are now removed, and alternative ones are added to the new functions. Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

2023-05-23e1000e: Reset packet state after emptying Tx queueAkihiko Odaki1-4/+2
Keeping Tx packet state after the transmit queue is emptied has some problems: - The datasheet says the descriptors can be reused after the transmit queue is emptied, but the Tx packet state may keep references to them. - The Tx packet state cannot be migrated so it can be reset anytime the migration happens.

Section 13.7.15 Receive Length Error Count says: > Packets over 1522 bytes are oversized if LongPacketEnable is 0b > (RCTL.LPE). If LongPacketEnable (LPE) is 1b, then an incoming packet > is considered oversized if it exceeds 16384 bytes. > These lengths are based on bytes in the received packet from > <Destination Address> through <CRC>, inclusively. As QEMU processes packets without CRC, the number of bytes for CRC need to be subtracted. This change adds some size definitions to be used to derive the new size thresholds to eth.h.
