2024-05-10drm/amdkfd: don't allow mapping the MMIO HDP page with large pagesAlex Deucher
We don't get the right offset in that case. The GPU has an unused 4K area of the register BAR space into which you can remap registers. We remap the HDP flush registers into this space to allow userspace (CPU or GPU) to flush the HDP when it updates VRAM. However, on systems with >4K pages, we end up exposing PAGE_SIZE of MMIO space.

2024-05-10x86/topology/amd: Ensure that LLC ID is initializedThomas Gleixner
The original topology evaluation code initialized cpu_data::topo::llc_id with the die ID initialy and then eventually overwrite it with information gathered from a CPUID leaf. The conversion analysis failed to spot that particular detail and omitted this initial assignment under the assumption that each topology evaluation path will set it up. That assumption is mostly correct, but turns out to be wrong in case that the CPUID leaf 0x80000006 does not provide a LLC ID. In that case, LLC ID is invalid and as a consequence the setup of the scheduling domain CPU masks is incorrect which subsequently causes the scheduler core to complain about it during CPU hotplug: BUG: arch topology borken the CLS domain not a subset of the MC domain Cure it by reusing legacy_set_llc() and assigning the die ID if the LLC ID is invalid after all possible parsers have been tried.

2024-05-10gpiolib: cdev: fix uninitialised kfifoKent Gibson
If a line is requested with debounce, and that results in debouncing in software, and the line is subsequently reconfigured to enable edge detection then the allocation of the kfifo to contain edge events is overlooked. This results in events being written to and read from an uninitialised kfifo. Read events are returned to userspace. Initialise the kfifo in the case where the software debounce is already active.

git://git.kernel.org/pub/scm/linux/kernel/git/pablo/gtp Pablo neira Ayuso says: ==================== gtp pull request 24-05-07 This v3 includes: - fix for clang uninitialized variable per Jakub. - address Smatch and Coccinelle reports per Simon - remove inline in new IPv6 support per Simon - fix memleaks in netlink control plane per Simon -o- The following patchset contains IPv6 GTP driver support for net-next, this also includes IPv6 over IPv4 and vice-versa: Patch #1 removes a unnecessary stack variable initialization in the socket routine. Patch #2 deals with GTP extension headers. This variable length extension header to decapsulate packets accordingly. Otherwise, packets are dropped when these extension headers are present which breaks interoperation with other non-Linux based GTP implementations. Patch #3 prepares for IPv6 support by moving IPv4 specific fields in PDP context objects to a union. Patch #4 adds IPv6 support while retaining backward compatibility. Three new attributes allows to declare an IPv6 GTP tunnel GTPA_FAMILY, GTPA_PEER_ADDR6 and GTPA_MS_ADDR6 as well as IFLA_GTP_LOCAL6 to declare the IPv6 GTP UDP socket. Up to this patch, only IPv6 outer in IPv6 inner is supported. Patch #5 uses IPv6 address /64 prefix for UE/MS in the inner headers. Unlike IPv4, which provides a 1:1 mapping between UE/MS, IPv6 tunnel encapsulates traffic for /64 address as specified by 3GPP TS. Patch has been split from Patch #4 to highlight this behaviour. Patch #6 passes up IPv6 link-local traffic, such as IPv6 SLAAC, for handling to userspace so they are handled as control packets. Patch #7 prepares to allow for GTP IPv4 over IPv6 and vice-versa by moving IP specific debugging out of the function to build IPv4 and IPv6 GTP packets. Patch #8 generalizes TOS/DSCP handling following similar approach as in the existing iptunnel infrastructure. Patch #9 adds a helper function to build an IPv4 GTP packet in the outer header. Patch #10 adds a helper function to build an IPv6 GTP packet in the outer header. Patch #11 adds support for GTP IPv4-over-IPv6 and vice-versa. Patch #12 allows to use the same TID/TEID (tunnel identifier) for inner IPv4 and IPv6 packets for better UE/MS dual stack integration. This series integrates with the osmocom.org project CI and TTCN-3 test infrastructure (Oliver Smith) as well as the userspace libgtpnl library. Thanks to Harald Welte, Oliver Smith and Pau Espin for reviewing and providing feedback through the osmocom.org redmine platform to make this happen. ==================== Signed-off-by: David S.

2024-05-10ALSA: Fix deadlocks with kctl removals at disconnectionTakashi Iwai
In snd_card_disconnect(), we set card->shutdown flag at the beginning, call callbacks and do sync for card->power_ref_sleep waiters at the end. The callback may delete a kctl element, and this can lead to a deadlock when the device was in the suspended state. Namely: * A process waits for the power up at snd_power_ref_and_wait() in snd_ctl_info() or read/write() inside card->controls_rwsem. * The system gets disconnected meanwhile, and the driver tries to delete a kctl via snd_ctl_remove*(); it tries to take card->controls_rwsem again, but this is already locked by the above. Since the sleeper isn't woken up, this deadlocks. An easy fix is to wake up sleepers before processing the driver disconnect callbacks but right after setting the card->shutdown flag. Then all sleepers will abort immediately, and the code flows again. So, basically this patch moves the wait_event() call at the right timing. While we're at it, just to be sure, call wait_event_all() instead of wait_event(), although we don't use exclusive events on this queue for now.

2024-05-10iommu/arm-smmu-v3: Make the kunit into a moduleJason Gunthorpe
It turns out kconfig has problems ensuring the SMMU module and the KUNIT module are consistently y/m to allow linking. It will permit KUNIT to be a module while SMMU is built in. Also, Fedora apparently enables kunit on production kernels. So, put the entire kunit in its own module using the VISIBLE_IF_KUNIT/EXPORT_SYMBOL_IF_KUNIT machinery. This keeps it out of vmlinus on Fedora and makes the kconfig work in the normal way. There is no cost if kunit is disabled.

Sven Auhagen reports transaction failures with following error: ./main.nft:13:1-26: Error: Could not process rule: Cannot allocate memory percpu: allocation failed, size=16 align=8 atomic=1, atomic alloc failed, no space left This points to failing pcpu allocation with GFP_ATOMIC flag. However, transactions happen from user context and are allowed to sleep. One case where we can call into percpu allocator with GFP_ATOMIC is nft_counter expression. Normally this happens from control plane, so this could use GFP_KERNEL instead. But one use case, element insertion from packet path, needs to use GFP_ATOMIC allocations (nft_dynset expression). At this time, .clone callbacks always use GFP_ATOMIC for this reason. Add gfp_t argument to the .clone function and pass GFP_KERNEL or GFP_ATOMIC flag depending on context, this allows all clone memory allocations to sleep for the normal (transaction) case.

RST packets with out-of-window sequence numbers are marked as INVALID 4. SYN+Challenge ACK: check that challenge ack is allowed to pass 5. Old SYN/ACK: check conntrack handles the case where SYN is answered with SYN/ACK for an old, previous connection attempt 6. Check SYN reception while in ESTABLISHED state generates a challenge ack, RST response clears 'outdated' state + next SYN retransmit gets us into 'SYN_RECV' conntrack state. Tests get run twice, once with ipv4 and once with ipv6. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2024-05-10ASoC: audio-graph-card2: call of_node_get() before of_get_next_child()Kuninori Morimoto
commit c6f597bc598a8 ("ASoC: audio-graph-card2: remove unneeded of_node_get()") removed of_node_get(), but it need to keep original reference, so of_node_get() itself is needed. Because of_get_next_child() will call of_node_put() inside, if the reference count dropped to zero, then of_node_get() after that will be use afer free. Need to call of_node_get() *before* that.

2024-05-10netfilter: nft_set_pipapo: move cloning of match info to insert/removal pathFlorian Westphal
This set type keeps two copies of the sets' content, priv->match (live version, used to match from packet path) priv->clone (work-in-progress version of the 'future' priv->match). All additions and removals are done on priv->clone. When transaction completes, priv->clone becomes priv->match and a new clone is allocated for use by next transaction. Problem is that the cloning requires GFP_KERNEL allocations but we cannot fail at either commit or abort time. This patch defers the clone until we get an insertion or removal request. This allows us to handle OOM situations correctly. This also allows to remove ->dirty in a followup change: If ->clone exists, ->dirty is always true If ->clone is NULL, ->dirty is always false, no elements were added or removed (except catchall elements which are external to the specific set backend).

The helper uses priv->clone unconditionally which will fail once we do the clone conditionally on first insert or removal. 'nft get element' from userspace needs to use priv->match since this runs from rcu read side lock section. Prepare for this by passing the match backend data as argument.

2024-05-10net: ipv6: fix wrong start position when receive hop-by-hop fragmentgaoxingwang
In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length. But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header, not the transport layer header or the first extension header. This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced, and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss. We can use network header to offset and calculate the correct position to solve this problem.

2024-05-10clocksource/drivers/renesas-ostm: Avoid reprobe after successful early probeGeert Uytterhoeven
The Renesas OS Timer (OSTM) driver contains two probe points, of which only one should complete: 1. Early probe, using TIMER_OF_DECLARE(), to provide the sole clocksource on (arm32) RZ/A1 and RZ/A2 SoCs, 2. Normal probe, using a platform driver, to provide additional timers on (arm64 + riscv) RZ/G2L and similar SoCs. The latter is needed because using OSTM on RZ/G2L requires manipulation of its reset signal, which is not yet available at the time of early probe, causing early probe to fail with -EPROBE_DEFER. It is only enabled when building a kernel with support for the RZ/G2L family, so it does not impact RZ/A1 and RZ/A2. Hence only one probe method can complete on all affected systems. As relying on the order of initialization of subsystems inside the kernel is fragile, set the DT node's OF_POPULATED flag after a succesful early probe. This makes sure the platform driver's probe is never called after a successful early probe.

2024-05-10clocksource/drivers/renesas-ostm: Allow OSTM driver to reprobe for RZ/V2H(P) SoCLad Prabhakar
The RZ/V2H(P) (R9A09G057) SoC is equipped with the Generic Timer Module, also known as OSTM. Similar to the RZ/G2L SoC, the OSTM on the RZ/V2H(P) SoC requires the reset line to be deasserted before accessing any registers. Early call to ostm_init() happens through TIMER_OF_DECLARE() which always fails with -EPROBE_DEFER, as resets are not available that early in the boot process. To address this issue on the RZ/V2H(P) SoC, enable the OSTM driver to be reprobed through the platform driver probe mechanism.
