2025-04-22net: phylink: fix suspend/resume with WoL enabled and link downRussell King (Oracle)
When WoL is enabled, we update the software state in phylink to indicate that the link is down, and disable the resolver from bringing the link back up. On resume, we attempt to bring the overall state into consistency by calling the .mac_link_down() method, but this is wrong if the link was already down, as phylink strictly orders the .mac_link_up() and .mac_link_down() methods - and this would break that ordering.

2025-04-22drm/amdgpu: Don't pin VRAM without DMABUF_MOVE_NOTIFYFelix Kuehling
Pinning of VRAM is for peer devices that don't support dynamic attachment and move notifiers. But it requires that all such peer devices are able to access VRAM via PCIe P2P. Any device without P2P access requires migration to GTT, which fails if the memory is already pinned for another peer device. Sharing between GPUs should not require pinning in VRAM. However, if DMABUF_MOVE_NOTIFY is disabled in the kernel build, even DMABufs shared between GPUs must be pinned, which can lead to failures and functional regressions on systems where some peer GPUs are not P2P accessible. Disable VRAM pinning if move notifiers are disabled in the kernel build to fix regressions when sharing BOs between GPUs.

2025-04-22net: phy: microchip: force IRQ polling mode for lan88xxFiona Klute
With lan88xx based devices the lan78xx driver can get stuck in an interrupt loop while bringing the device up, flooding the kernel log with messages like the following: lan78xx 2-3:1.0 enp1s0u3: kevent 4 may have been dropped Removing interrupt support from the lan88xx PHY driver forces the driver to use polling instead, which avoids the problem. The issue has been observed with Raspberry Pi devices at least since 4.14 (see [1], bug report for their downstream kernel), as well as with Nvidia devices [2] in 2020, where disabling interrupts was the vendor-suggested workaround (together with the claim that phylib changes in 4.9 made the interrupt handling in lan78xx incompatible). Iperf reports well over 900Mbits/sec per direction with client in --dualtest mode, so there does not seem to be a significant impact on throughput (lan88xx device connected via switch to the peer).

Relevant function call stack: (drm framework) -> meson_encoder_hdmi_atomic_enable() -> meson_encoder_hdmi_set_vclk() -> meson_vclk_setup() The video clock requested by the drm framework is 593407kHz. This is passed by meson_encoder_hdmi_atomic_enable() to meson_encoder_hdmi_set_vclk() and the following formula is applied: - the frequency is halved (which would be 296703.5kHz) and rounded down to the next full integer, which is 296703kHz - TMDS clock is calculated (296703kHz * 10) - video encoder clock is calculated - this needs to match a table from meson_vclk.c and so it doubles the previously halved value again (resulting in 593406kHz) - meson_vclk_setup() can't find (either directly, or by deriving it from 594000kHz * 1000 / 1001 and rounding to the closest integer value - which is 593407kHz as originally requested by the drm framework) a matching clock in it's internal table and errors out with "invalid HDMI vclk freq" Fix the division precision by switching the whole meson driver to use unsigned long long (64-bit) Hz values for clock frequencies instead of unsigned int (32-bit) kHz to fix the rouding error.

2025-04-22scsi: Improve CDL controlDamien Le Moal
With ATA devices supporting the CDL feature, using CDL requires that the feature be enabled with a SET FEATURES command. This command is issued as the translated command for the MODE SELECT command issued by scsi_cdl_enable() when the user enables CDL through the device cdl_enable sysfs attribute. However, the implementation of scsi_cdl_enable() always issues a MODE SELECT command for ATA devices when the enable argument is true, even if CDL is already enabled on the device. While this does not cause any issue with using CDL descriptors with read/write commands (the CDL feature will be enabled on the drive), issuing the MODE SELECT command even when the device CDL feature is already enabled will cause a reset of the ATA device CDL statistics log page (as defined in ACS, any CDL enable action must reset the device statistics). Avoid this needless actions (and the implied statistics log page reset) by modifying scsi_cdl_enable() to issue the MODE SELECT command to enable CDL if and only if CDL is not reported as already enabled on the device. And while at it, simplify the initialization of the is_ata boolean variable and move the declaration of the scsi mode data and sense header variables to within the scope of ATA device handling.

This command is issued as the translated command for the MODE SELECT command issued by scsi_cdl_enable() when the user enables CDL through the device cdl_enable sysfs attribute. Currently, ata_mselect_control_ata_feature() always translates a MODE SELECT command for the ATA features subpage of the control mode page to a SET FEATURES command to enable or disable CDL based on the cdl_ctrl field.

Fix ata_mselect_control_ata_feature() to issue the SET FEATURES command only when necessary.

2025-04-21net: enetc: fix frame corruption on bpf_xdp_adjust_head/tail() and XDP_PASSVladimir Oltean
Vlatko Markovikj reported that XDP programs attached to ENETC do not work well if they use bpf_xdp_adjust_head() or bpf_xdp_adjust_tail(), combined with the XDP_PASS verdict. A typical use case is to add or remove a VLAN tag. The resulting sk_buff passed to the stack is corrupted, because the algorithm used by the driver for XDP_PASS is to unwind the current buffer pointer in the RX ring and to re-process the current frame with enetc_build_skb() as if XDP hadn't run. That is incorrect because XDP may have modified the geometry of the buffer, which we then are completely unaware of. We are looking at a modified buffer with the original geometry. The initial reaction, both from me and from Vlatko, was to shop around the kernel for code to steal that would calculate a delta between the old and the new XDP buffer geometry, and apply that to the sk_buff too. We noticed that veth and generic xdp have such code. The headroom adjustment is pretty uncontroversial, but what turned out severely problematic is the tailroom. veth has this snippet: __skb_put(skb, off); /* positive on grow, negative on shrink */ which on first sight looks decent enough, except __skb_put() takes an "unsigned int" for the second argument, and the arithmetic seems to only work correctly by coincidence. Second issue, __skb_put() contains a SKB_LINEAR_ASSERT(). It's not a great pattern to make more widespread. The skb may still be nonlinear at that point - it only becomes linear later when resetting skb->data_len to zero. To avoid the above, bpf_prog_run_generic_xdp() does this instead: skb_set_tail_pointer(skb, xdp->data_end - xdp->data); skb->len += off; /* positive on grow, negative on shrink */ which is more open-coded, uses lower-level functions and is in general a bit too much to spread around in driver code. Then there is the snippet: if (xdp_buff_has_frags(xdp)) skb->data_len = skb_shinfo(skb)->xdp_frags_size; else skb->data_len = 0; One would have expected __pskb_trim() to be the function of choice for this task. But it's not used in veth/xdpgeneric because the extraneous fragments were _already_ freed by bpf_xdp_adjust_tail() -> bpf_xdp_frags_shrink_tail() -> ... -> __xdp_return() - the backing memory for the skb frags and the xdp frags is the same, but they don't keep individual references. In fact, that is the biggest reason why this snippet cannot be reused as-is, because ENETC temporarily constructs an skb with the original len and the original number of frags. Because the extraneous frags are already freed by bpf_xdp_adjust_tail() and returned to the page allocator, it means the entire approach of using enetc_build_skb() is questionable for XDP_PASS. To avoid that, one would need to elevate the page refcount of all frags before calling bpf_prog_run_xdp() and drop it after XDP_PASS. There are other things that are missing in ENETC's handling of XDP_PASS, like for example updating skb_shinfo(skb)->meta_len. These are all handled correctly and cleanly in commit 539c1fba1ac7 ("xdp: add generic xdp_build_skb_from_buff()"), added to net-next in Dec 2024, and in addition might even be quicker that way. I have a very strong preference towards backporting that commit for "stable", and that is what is used to fix the handling bugs. It is way too messy to go this deep into the guts of an sk_buff from the code of a device driver.

2025-04-21net: enetc: refactor bulk flipping of RX buffers to separate functionVladimir Oltean
This small snippet of code ensures that we do something with the array of RX software buffer descriptor elements after passing the skb to the stack. In this case, we see if the other half of the page is reusable, and if so, we "turn around" the buffers, making them directly usable by enetc_refill_rx_ring() without going to enetc_new_page(). We will need to perform this kind of buffer flipping from a new code path, i.e. from XDP_PASS. Currently, enetc_build_skb() does it there buffer by buffer, but in a subsequent change we will stop using enetc_build_skb() for XDP_PASS.

2025-04-21net: enetc: register XDP RX queues with frag_sizeVladimir Oltean
At the time when bpf_xdp_adjust_tail() gained support for non-linear buffers, ENETC was already generating this kind of geometry on RX, due to its use of 2K half page buffers. Frames larger than 1472 bytes (without FCS) are stored as multi-buffer, presenting a need for multi buffer support to work properly even in standard MTU circumstances. Allow bpf_xdp_frags_increase_tail() to know the allocation size of paged data, so it can safely permit growing the tailroom of the buffer from XDP programs.

2025-04-21xen-netfront: handle NULL returned by xdp_convert_buff_to_frame()Alexey Nepomnyashih
The function xdp_convert_buff_to_frame() may return NULL if it fails to correctly convert the XDP buffer into an XDP frame due to memory constraints, internal errors, or invalid data. Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior. On XDP redirect failure, the associated page must be released explicitly if it was previously retained via get_page(). Failing to do so may result in a memory leak, as the pages reference count is not decremented.

2025-04-21cxl/core/regs.c: Skip Memory Space Enable check for RCD and RCH PortsSmita Koralahalli
According to CXL r3.2 section 8.2.1.2, the PCI_COMMAND register fields, including Memory Space Enable bit, have no effect on the behavior of an RCD Upstream Port. Retaining this check may incorrectly cause cxl_pci_probe() to fail on a valid RCD upstream Port. While the specification is explicit only for RCD Upstream Ports, this check is solely for accessing the RCRB, which is always mapped through memory space. Therefore, its safe to remove the check entirely. In practice, firmware reliably enables the Memory Space Enable bit for RCH Downstream Ports and no failures have been observed. Removing the check simplifies the code and avoids unnecessary special-casing, while relying on BIOS/firmware to configure devices correctly. Moreover, any failures due to inaccessible RCRB regions will still be caught either in __rcrb_to_component() or while parsing the component register block. The following failure was observed in dmesg when the check was present: cxl_pci 0000:7f:00.0: No component registers (-6) Fixes: d5b1a27143cb ("cxl/acpi: Extract component registers of restricted hosts from RCRB") Signed-off-by: Smita Koralahalli <Smita.KoralahalliChannabasappa@amd.com> Cc: <stable@vger.kernel.org> Reviewed-by: Ira Weiny <ira.weiny@intel.com> Reviewed-by: Terry Bowman <terry.bowman@amd.com> Reviewed-by: Dave Jiang <dave.jiang@intel.com> Reviewed-by: Robert Richter <rrichter@amd.com> Link: https://patch.msgid.link/20250407192734.70631-1-Smita.KoralahalliChannabasappa@amd.com Signed-off-by: Dave Jiang <dave.jiang@intel.com>

2025-04-20gcc-15: disable '-Wunterminated-string-initialization' entirely for nowLinus Torvalds
I had left the warning around but as a non-fatal error to get my gcc-15 builds going, but fixed up some of the most annoying warning cases so that it wouldn't be *too* verbose. Because I like the _concept_ of the warning, even if I detested the implementation to shut it up. It turns out the implementation to shut it up is even more broken than I thought, and my "shut up most of the warnings" patch just caused fatal errors on gcc-14 instead. I had tested with clang, but when I upgrade my development environment, I try to do it on all machines because I hate having different systems to maintain, and hadn't realized that gcc-14 now had issues. The ACPI case is literally why I wanted to have a *type* that doesn't trigger the warning (see commit d5d45a7f2619: "gcc-15: make 'unterminated string initialization' just a warning"), instead of marking individual places as "__nonstring". But gcc-14 doesn't like that __nonstring location that shut gcc-15 up, because it's on an array of char arrays, not on one single array: drivers/acpi/tables.c:399:1: error: 'nonstring' attribute ignored on objects of type 'const char[][4]' [-Werror=attributes] 399 | static const char table_sigs[][ACPI_NAMESEG_SIZE] __initconst __nonstring = { | ^~~~~~ and my attempts to nest it properly with a type had failed, because of how gcc doesn't like marking the types as having attributes, only symbols. There may be some trick to it, but I was already annoyed by the bad attribute design, now I'm just entirely fed up with it. I wish gcc had a proper way to say "this type is a *byte* array, not a string". The obvious thing would be to distinguish between "char []" and an explicitly signed "unsigned char []" (as opposed to an implicitly unsigned char, which is typically an architecture-specific default, but for the kernel is universal thanks to '-funsigned-char'). But any "we can typedef a 8-bit type to not become a string just because it's an array" model would be fine. But "__attribute__((nonstring))" is sadly not that sane model.

2025-04-20gcc-15: work around sequence-point warningLinus Torvalds
The C sequence points are complicated things, and gcc-15 has apparently added a warning for the case where an object is both used and modified multiple times within the same sequence point. That's a great warning. Or rather, it would be a great warning, except gcc-15 seems to not really be very exact about it, and doesn't notice that the modification are to two entirely different members of the same object: the array counter and the array entries. So that seems kind of silly. That said, the code that gcc complains about is unnecessarily complicated, so moving the array counter update into a separate statement seems like the most straightforward fix for these warnings: drivers/net/wireless/intel/iwlwifi/mld/d3.c: In function ‘iwl_mld_set_netdetect_info’: drivers/net/wireless/intel/iwlwifi/mld/d3.c:1102:66: error: operation on ‘netdetect_info->n_matches’ may be undefined [-Werror=sequence-point] 1102 | netdetect_info->matches[netdetect_info->n_matches++] = match; | ~~~~~~~~~~~~~~~~~~~~~~~~~^~ drivers/net/wireless/intel/iwlwifi/mld/d3.c:1120:58: error: operation on ‘match->n_channels’ may be undefined [-Werror=sequence-point] 1120 | match->channels[match->n_channels++] = | ~~~~~~~~~~~~~~~~~^~ side note: the code at that second warning is actively buggy, and only works on little-endian machines that don't do strict alignment checks. The code casts an array of integers into an array of unsigned long in order to use our bitmap iterators. That happens to work fine on any sane architecture, but it's still wrong. This does *not* fix that more serious problem. This only splits the two assignments into two statements and fixes the compiler warning. I need to get rid of the new warnings in order to be able to actually do any build testing. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2025-04-20gcc-15: add '__nonstring' markers to byte arraysLinus Torvalds
All of these cases are perfectly valid and good traditional C, but hit by the "you're not NUL-terminating your byte array" warning. And none of the cases want any terminating NUL character. Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974 magnetometer driver, I just removed the explicit array size and let gcc expand the 3-byte and 6-byte arrays by one extra byte, because it was the simpler change).

2025-04-20gcc-15: get rid of misc extra NUL character paddingLinus Torvalds
This removes two cases of explicit NUL padding that now causes warnings because of '-Wunterminated-string-initialization' being part of -Wextra in gcc-15. Gcc is being silly in this case when it says that it truncates a NUL terminator, because in these cases there were _multiple_ NUL characters. But we can get rid of the warning by just simplifying the two initializers that trigger the warning for me, so this does exactly that. I'm not sure why the power supply code did that odd .attr_name = #_name "\0", pattern: it was introduced in commit 2cabeaf15129 ("power: supply: core: Cleanup power supply sysfs attribute list"), but that 'attr_name[]' field is an explicitly sized character array in a statically initialized variable, and a string initializer always has a terminating NUL _and_ statically initialized character arrays are zero-padded anyway, so it really seems to be rather extraneous belt-and-suspenders. The zero_uuid[16] initialization in drivers/md/bcache/super.c makes perfect sense, but it isn't necessary for the same reasons, and not worth the new gcc warning noise.

2025-04-20gcc-15: acpi: sprinkle random '__nonstring' crumbles aroundLinus Torvalds
This is not great: I'd much rather introduce a typedef that is a "ACPI name byte buffer", and use that to mark these special 4-byte ACPI names that do not use NUL termination. But as noted in the previous commit ("gcc-15: make 'unterminated string initialization' just a warning") gcc doesn't actually seem to support that notion, so instead you have to just mark every single array declaration individually. So this is not pretty, but this gets rid of the bulk of the annoying warnings during an allmodconfig build for me. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

IB_SIZE is only b0..b19. Starting with a6xx gen3, additional fields were added above the IB_SIZE. Accidentially setting them can cause badness. Fix this by properly defining the CP_INDIRECT_BUFFER packet and using the generated builder macro to ensure unintended bits are not set. v2: add missing type attribute for IB_BASE v3: fix offset attribute in xml Reported-by: Connor Abbott <cwabbott0@gmail.com> Fixes: a83366ef19ea ("drm/msm/a6xx: add A640/A650 to gpulist") Signed-off-by: Rob Clark <robdclark@chromium.org> Patchwork: https://patchwork.freedesktop.org/patch/643396/
