2023-07-27x86/srso: Add IBPB_BRTYPE supportBorislav Petkov (AMD)
Add support for the synthetic CPUID flag which "if this bit is 1, it indicates that MSR 49h (PRED_CMD) bit 0 (IBPB) flushes all branch type predictions from the CPU branch predictor." This flag is there so that this capability in guests can be detected easily (otherwise one would have to track microcode revisions which is impossible for guests). It is also needed only for Zen3 and -4. The other two (Zen1 and -2) always flush branch type predictions by default. Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de>
2023-07-27x86/srso: Add a Speculative RAS Overflow mitigationBorislav Petkov (AMD)
Add a mitigation for the speculative return address stack overflow vulnerability found on AMD processors. The mitigation works by ensuring all RET instructions speculate to a controlled location, similar to how speculation is controlled in the retpoline sequence. To accomplish this, the __x86_return_thunk forces the CPU to mispredict every function return using a 'safe return' sequence. To ensure the safety of this mitigation, the kernel must ensure that the safe return sequence is itself free from attacker interference. In Zen3 and Zen4, this is accomplished by creating a BTB alias between the untraining function srso_untrain_ret_alias() and the safe return function srso_safe_ret_alias() which results in evicting a potentially poisoned BTB entry and using that safe one for all function returns. In older Zen1 and Zen2, this is accomplished using a reinterpretation technique similar to Retbleed one: srso_untrain_ret() and srso_safe_ret(). Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de>

2023-07-27usb: dwc3: pci: skip BYT GPIO lookup table for hardwired phyGratian Crisan
Hardware based on the Bay Trail / BYT SoCs require an external ULPI phy for USB device-mode. The phy chip usually has its 'reset' and 'chip select' lines connected to GPIOs described by ACPI fwnodes in the DSDT table. Because of hardware with missing ACPI resources for the 'reset' and 'chip select' GPIOs commit 5741022cbdf3 ("usb: dwc3: pci: Add GPIO lookup table on platforms without ACPI GPIO resources") introduced a fallback gpiod_lookup_table with hard-coded mappings for Bay Trail devices. However there are existing Bay Trail based devices, like the National Instruments cRIO-903x series, where the phy chip has its 'reset' and 'chip-select' lines always asserted in hardware via resistor pull-ups. On this hardware the phy chip is always enabled and the ACPI dsdt table is missing information not only for the 'chip-select' and 'reset' lines but also for the BYT GPIO controller itself "INT33FC". With the introduction of the gpiod_lookup_table initializing the USB device-mode on these hardware now errors out. The error comes from the gpiod_get_optional() calls in dwc3_pci_quirks() which will now return an -ENOENT error due to the missing ACPI entry for the INT33FC gpio controller used in the aforementioned table. This hardware used to work before because gpiod_get_optional() will return NULL instead of -ENOENT if no GPIO has been assigned to the requested function. The dwc3_pci_quirks() code for setting the 'cs' and 'reset' GPIOs was then skipped (due to the NULL return). This is the correct behavior in cases where the phy chip is hardwired and there are no GPIOs to control. Since the gpiod_lookup_table relies on the presence of INT33FC fwnode in ACPI tables only add the table if we know the entry for the INT33FC gpio controller is present. This allows Bay Trail based devices with hardwired dwc3 ULPI phys to continue working.

2023-07-27xen: speed up grant-table reclaimDemi Marie Obenour
When a grant entry is still in use by the remote domain, Linux must put it on a deferred list. Normally, this list is very short, because the PV network and block protocols expect the backend to unmap the grant first. However, Qubes OS's GUI protocol is subject to the constraints of the X Window System, and as such winds up with the frontend unmapping the window first. As a result, the list can grow very large, resulting in a massive memory leak and eventual VM freeze. To partially solve this problem, make the number of entries that the VM will attempt to free at each iteration tunable. The default is still 10, but it can be overridden via a module parameter. This is Cc: stable because (when combined with appropriate userspace changes) it fixes a severe performance and stability problem for Qubes OS users.

2023-07-26virtio-net: fix race between set queues and probeJason Wang
A race were found where set_channels could be called after registering but before virtnet_set_queues() in virtnet_probe(). Fixing this by moving the virtnet_set_queues() before netdevice registering. While at it, use _virtnet_set_queues() to avoid holding rtnl as the device is not even registered at that time.

2023-07-26net/sched: mqprio: Add length check for TCA_MQPRIO_{MAX/MIN}_RATE64Lin Ma
The nla_for_each_nested parsing in function mqprio_parse_nlattr() does not check the length of the nested attribute. This can lead to an out-of-attribute read and allow a malformed nlattr (e.g., length 0) to be viewed as 8 byte integer and passed to priv->max_rate/min_rate. This patch adds the check based on nla_len() when check the nla_type(), which ensures that the length of these two attribute must equals sizeof(u64).

2023-07-26splice, net: Fix splice_to_socket() for O_NONBLOCK socketJan Stancek
LTP sendfile07 [1], which expects sendfile() to return EAGAIN when transferring data from regular file to a "full" O_NONBLOCK socket, started failing after commit 2dc334f1a63a ("splice, net: Use sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()"). sendfile() no longer immediately returns, but now blocks. Removed sock_sendpage() handled this case by setting a MSG_DONTWAIT flag, fix new splice_to_socket() to do the same for O_NONBLOCK sockets.

According to the clarification [1] in the latest napi.rst, the tx processing cannot call any XDP (or page pool) APIs if the "budget" is 0. Because NAPI is called with the budget of 0 (such as netpoll) indicates we may be in an IRQ context, however, we cannot use the page pool from IRQ context.
