remoteproc: stm32: fix incorrect optional pointers

2024-03-26T22:21:03Z

commit fb2bdd32b231b70e6a3f1054528692f604db25d8 upstream. Compile-testing without CONFIG_OF shows that the of_match_ptr() macro was used incorrectly here: drivers/remoteproc/stm32_rproc.c:662:34: warning: unused variable 'stm32_rproc_match' [-Wunused-const-variable] As in almost every driver, the solution is simply to remove the use of this macro. The same thing happened with the deprecated SIMPLE_DEV_PM_OPS(), but the corresponding warning was already shut up with __maybe_unused annotations, so fix those as well by using the correct DEFINE_SIMPLE_DEV_PM_OPS() macros and removing the extraneous __maybe_unused modifiers. For completeness, also add a pm_ptr() to let the PM ops be eliminated completely when CONFIG_PM is turned off.

x86/efistub: Don't clear BSS twice in mixed mode

2024-03-26T22:21:03Z

[ Upstream commit df7ecce842b846a04d087ba85fdb79a90e26a1b0 ] Clearing BSS should only be done once, at the very beginning. efi_pe_entry() is the entrypoint from the firmware, which may not clear BSS and so it is done explicitly. However, efi_pe_entry() is also used as an entrypoint by the mixed mode startup code, in which case BSS will already have been cleared, and doing it again at this point will corrupt global variables holding the firmware's GDT/IDT and segment selectors. So make the memset() conditional on whether the EFI stub is running in native mode.

x86/efistub: Clear decompressor BSS in native EFI entrypoint

2024-03-26T22:21:03Z

[ Upstream commit b3810c5a2cc4a6665f7a65bed5393c75ce3f3aa2 ] The EFI stub on x86 no longer invokes the decompressor as a subsequent boot stage, but calls into the decompression code directly while running in the context of the EFI boot services. This means that when using the native EFI entrypoint (as opposed to the EFI handover protocol, which clears BSS explicitly), the firmware PE image loader is being relied upon to ensure that BSS is zeroed before the EFI stub is entered from the firmware. As Radek's report proves, this is a bad idea. Not all loaders do this correctly, which means some global variables that should be statically initialized to 0x0 may have junk in them. So clear BSS explicitly when entering via efi_pe_entry(). Note that zeroing BSS from C code is not generally safe, but in this case, the following assignment and dereference of a global pointer variable ensures that the memset() cannot be deferred or reordered.

dm-integrity: align the outgoing bio in integrity_recheck

2024-03-26T22:21:03Z

[ Upstream commit b4d78cfeb30476239cf08f4f40afc095c173d6e3 ] It is possible to set up dm-integrity with smaller sector size than the logical sector size of the underlying device. In this situation, dm-integrity guarantees that the outgoing bios have the same alignment as incoming bios (so, if you create a filesystem with 4k block size, dm-integrity would send 4k-aligned bios to the underlying device). This guarantee was broken when integrity_recheck was implemented. integrity_recheck sends bio that is aligned to ic->sectors_per_block. So if we set up integrity with 512-byte sector size on a device with logical block size 4k, we would be sending unaligned bio. This triggered a bug in one of our internal tests. This commit fixes it by determining the actual alignment of the incoming bio and then makes sure that the outgoing bio in integrity_recheck has the same alignment.

selftests: forwarding: Fix ping failure due to short timeout

2024-03-26T22:21:02Z

[ Upstream commit e4137851d4863a9bdc6aabc613bcb46c06d91e64 ] The tests send 100 pings in 0.1 second intervals and force a timeout of 11 seconds, which is borderline (especially on debug kernels), resulting in random failures in netdev CI [1]. Fix by increasing the timeout to 20 seconds. It should not prolong the test unless something is wrong, in which case the test will rightfully fail.

net: dsa: mt7530: fix handling of all link-local frames

2024-03-26T22:21:02Z

[ Upstream commit 69ddba9d170bdaee1dc0eb4ced38d7e4bb7b92af ] Currently, the MT753X switches treat frames with :01-0D and :0F MAC DAs as regular multicast frames, therefore flooding them to user ports. On page 205, section "8.6.3 Frame filtering" of the active standard, IEEE Std 802.1Q™-2022, it is stated that frames with 01:80:C2:00:00:00-0F as MAC DA must only be propagated to C-VLAN and MAC Bridge components. That means VLAN-aware and VLAN-unaware bridges. On the switch designs with CPU ports, these frames are supposed to be processed by the CPU (software). So we make the switch only forward them to the CPU port. And if received from a CPU port, forward to a single port. The software is responsible of making the switch conform to the latter by setting a single port as destination port on the special tag. This switch intellectual property cannot conform to this part of the standard fully. Whilst the REV_UN frame tag covers the remaining :04-0D and :0F MAC DAs, it also includes :22-FF which the scope of propagation is not supposed to be restricted for these MAC DAs. Set frames with :01-03 MAC DAs to be trapped to the CPU port(s). Add a comment for the remaining MAC DAs. Note that the ingress port must have a PVID assigned to it for the switch to forward untagged frames. A PVID is set by default on VLAN-aware and VLAN-unaware ports. However, when the network interface that pertains to the ingress port is attached to a vlan_filtering enabled bridge, the user can remove the PVID assignment from it which would prevent the link-local frames from being trapped to the CPU port. I am yet to see a way to forward link-local frames while preventing other untagged frames from being forwarded too.
