2023-10-09riscv, bpf: Track both a0 (RISC-V ABI) and a5 (BPF) return valuesBjörn Töpel
The RISC-V BPF uses a5 for BPF return values, which are zero-extended, whereas the RISC-V ABI uses a0 which is sign-extended. In other words, a5 and a0 can differ, and are used in different context. The BPF trampoline are used for both BPF programs, and regular kernel functions. Make sure that the RISC-V BPF trampoline saves, and restores both a0 and a5.

2023-10-09riscv, bpf: Sign-extend return valuesBjörn Töpel
The RISC-V architecture does not expose sub-registers, and hold all 32-bit values in a sign-extended format [1] [2]: | The compiler and calling convention maintain an invariant that all | 32-bit values are held in a sign-extended format in 64-bit | registers. Even 32-bit unsigned integers extend bit 31 into bits | 63 through 32. Consequently, conversion between unsigned and | signed 32-bit integers is a no-op, as is conversion from a signed | 32-bit integer to a signed 64-bit integer. While BPF, on the other hand, exposes sub-registers, and use zero-extension (similar to arm64/x86). This has led to some subtle bugs, where a BPF JITted program has not sign-extended the a0 register (return value in RISC-V land), passed the return value up the kernel, e.g.: | int from_bpf(void); | | long foo(void) | { | return from_bpf(); | } Here, a0 would be 0xffff_ffff, instead of the expected 0xffff_ffff_ffff_ffff. Internally, the RISC-V JIT uses a5 as a dedicated register for BPF return values. Keep a5 zero-extended, but explicitly sign-extend a0 (which is used outside BPF land). Now that a0 (RISC-V ABI) and a5 (BPF ABI) differs, a0 is only moved to a5 for non-BPF native calls (BPF_PSEUDO_CALL).

2023-10-09printk: flush consoles before checking progressJohn Ogness
Commit 9e70a5e109a4 ("printk: Add per-console suspended state") removed console lock usage during resume and replaced it with the clearly defined console_list_lock and srcu mechanisms. However, the console lock usage had an important side-effect of flushing the consoles. After its removal, consoles were no longer flushed before checking their progress. Add the console_lock/console_unlock dance to the beginning of __pr_flush() to actually flush the consoles before checking their progress. Also add comments to clarify this additional usage of the console lock. Note that console_unlock() does not guarantee flushing all messages since the commit dbdda842fe96f89 ("printk: Add console owner and waiter logic to load balance console writes").

2023-10-09xen/events: replace evtchn_rwlock with RCUJuergen Gross
In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. Normally this is no problem, as the evtchn_rwlock is taken as a reader in both paths, but as soon as an event channel is being closed, the lock will be taken as a writer, which will cause read_lock() to block: CPU0 CPU1 CPU2 (IRQ handling) (__hvc_poll()) (closing event channel) read_lock(evtchn_rwlock) spin_lock(hvc_lock) write_lock(evtchn_rwlock) [blocks] spin_lock(hvc_lock) [blocks] read_lock(evtchn_rwlock) [blocks due to writer waiting, and not in_interrupt()] This issue can be avoided by replacing evtchn_rwlock with RCU in xen_free_irq(). Note that RCU is used only to delay freeing of the irq_info memory. There is no RCU based dereferencing or replacement of pointers involved. In order to avoid potential races between removing the irq_info reference and handling of interrupts, set the irq_info pointer to NULL only when freeing its memory. The IRQ itself must be freed at that time, too, as otherwise the same IRQ number could be allocated again before handling of the old instance would have been finished. This is XSA-441 / CVE-2023-34324.

2023-10-08ice: block default rule setting on LAG interfaceMichal Swiatkowski
When one of the LAG interfaces is in switchdev mode, setting default rule can't be done. The interface on which switchdev is running has ice_set_rx_mode() blocked to avoid default rule adding (and other rules). The other interfaces (without switchdev running but connected via bond with interface that runs switchdev) can't follow the same scheme, because rx filtering needs to be disabled when failover happens. Notification for bridge to set promisc mode seems like good place to do that.

2023-10-08xen-netback: use default TX queue size for vifsRoger Pau Monne
Do not set netback interfaces (vifs) default TX queue size to the ring size. The TX queue size is not related to the ring size, and using the ring size (32) as the queue size can lead to packet drops. Note the TX side of the vif interface in the netback domain is the one receiving packets to be injected to the guest. Do not explicitly set the TX queue length to any value when creating the interface, and instead use the system default. Note that the queue length can also be adjusted at runtime.

If of_clk_add_provider() fails in ca8210_register_ext_clock(), it calls clk_unregister() to release priv->clk and returns an error. However, the caller ca8210_probe() then calls ca8210_remove(), where priv->clk is freed again in ca8210_unregister_ext_clock(). In this case, a use-after-free may happen in the second time we call clk_unregister(). Fix this by removing the first clk_unregister(). Also, priv->clk could be an error code on failure of clk_register_fixed_rate(). Use IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().

2023-10-07parisc: Restore __ldcw_align for PA-RISC 2.0 processorsJohn David Anglin
Back in 2005, Kyle McMartin removed the 16-byte alignment for ldcw semaphores on PA 2.0 machines (CONFIG_PA20). This broke spinlocks on pre PA8800 processors. The main symptom was random faults in mmap'd memory (e.g., gcc compilations, etc). Unfortunately, the errata for this ldcw change is lost. The issue is the 16-byte alignment required for ldcw semaphore instructions can only be reduced to natural alignment when the ldcw operation can be handled coherently in cache. Only PA8800 and PA8900 processors actually support doing the operation in cache. Aligning the spinlock dynamically adds two integer instructions to each spinlock. Tested on rp3440, c8000 and a500.

2023-10-07MAINTAINERS: Remove myself from the general IRQ subsystem maintenanceMarc Zyngier
It is pretty obvious that I haven't done much on the IRQ side for a while, and it is unlikely that I'll have more bandwidth for it any time soon. People keep sending me patches that I end-up reviewing in a cursory manner, which isn't great for anyone. So in everyone's interest, I'm removing myself from the list of maintainers and leave the irqchip and irqdomain subsystems in Thomas' capable hands.

2023-10-07irqchip/riscv-intc: Mark all INTC nodes as initializedAnup Patel
The RISC-V INTC local interrupts are per-HART (or per-CPU) so we create INTC IRQ domain only for the INTC node belonging to the boot HART. This means only the boot HART INTC node will be marked as initialized and other INTC nodes won't be marked which results downstream interrupt controllers (such as PLIC, IMSIC and APLIC direct-mode) not being probed due to missing device suppliers. To address this issue, we mark all INTC node for which we don't create IRQ domain as initialized.

2023-10-07irqchip/gic-v3: Enable non-coherent redistributors/ITSes DT probingLorenzo Pieralisi
The GIC architecture specification defines a set of registers for redistributors and ITSes that control the sharebility and cacheability attributes of redistributors/ITSes initiator ports on the interconnect (GICR_[V]PROPBASER, GICR_[V]PENDBASER, GITS_BASER<n>). Architecturally the GIC provides a means to drive shareability and cacheability attributes signals and related IWB/OWB/ISH barriers but it is not mandatory for designs to wire up the corresponding interconnect signals that control the cacheability/shareability of transactions. Redistributors and ITSes interconnect ports can be connected to non-coherent interconnects that are not able to manage the shareability/cacheability attributes; this implicitly makes the redistributors and ITSes non-coherent observers. So far, the GIC driver on probe executes a write to "probe" for the redistributors and ITSes registers shareability bitfields by writing a value (ie InnerShareable - the shareability domain the CPUs are in) and check it back to detect whether the value sticks or not; this hinges on a GIC programming model behaviour that predates the current specifications, that just define shareability bits as writeable but do not guarantee that writing certain shareability values enable the expected behaviour for the redistributors/ITSes memory interconnect ports. To enable non-coherent GIC designs, introduce the "dma-noncoherent" device tree property to allow firmware to describe redistributors and ITSes as non-coherent observers on the memory interconnect and use the property to force the shareability attributes to be programmed into the redistributors and ITSes registers through the GIC quirks mechanism.

2023-10-06selftests/bpf: Make seen_tc* variable tests more robustDaniel Borkmann
Martin reported that on his local dev machine the test_tc_chain_mixed() fails as "test_tc_chain_mixed:FAIL:seen_tc5 unexpected seen_tc5: actual 1 != expected 0" and others occasionally, too. However, when running in a more isolated setup (qemu in particular), it works fine for him. The reason is that there is a small race-window where seen_tc* could turn into true for various test cases when there is background traffic, e.g. after the asserts they often get reset. In such case when subsequent detach takes place, unrelated background traffic could have already flipped the bool to true beforehand. Add a small helper tc_skel_reset_all_seen() to reset all bools before we do the ping test. At this point, everything is set up as expected and therefore no race can occur. All tc_{opts,links} tests continue to pass after this change.

2023-10-06bpf: Refuse unused attributes in bpf_prog_{attach,detach}Lorenz Bauer
The recently added tcx attachment extended the BPF UAPI for attaching and detaching by a couple of fields. Those fields are currently only supported for tcx, other types like cgroups and flow dissector silently ignore the new fields except for the new flags. This is problematic once we extend bpf_mprog to older attachment types, since it's hard to figure out whether the syscall really was successful if the kernel silently ignores non-zero values. Explicitly reject non-zero fields relevant to bpf_mprog for attachment types which don't use the latter yet.

2023-10-06bpf: Fix BPF_PROG_QUERY last field checkDaniel Borkmann
While working on the ebpf-go [0] library integration for bpf_mprog and tcx, Lorenz noticed that two subsequent BPF_PROG_QUERY requests currently fail. A typical workflow is to first gather the bpf_mprog count without passing program/ link arrays, followed by the second request which contains the actual array pointers. The initial call populates count and revision fields. The second call gets rejected due to a BPF_PROG_QUERY_LAST_FIELD bug which should point to query.revision instead of query.link_attach_flags since the former is really the last member. It was not noticed in libbpf as bpf_prog_query_opts() always calls bpf(2) with an on-stack bpf_attr that is memset() each time (and therefore query.revision was reset to zero).
