2024-05-02gfs2: Simplify gfs2_read_superMatthew Wilcox (Oracle)
Use submit_bio_wait() instead of hand-rolling our own synchronous wait. Also allocate the BIO on the stack since we're not deep in the call stack at this point. There's no need to kmap the page, since it isn't allocated from HIGHMEM. Turn the GFP_NOFS allocation into GFP_KERNEL; if the page allocator enters reclaim, we cannot be called as the filesystem has not yet been initialised and so has no pages to reclaim.

2024-05-02x86/xen: return a sane initial apic id when running as PV guestJuergen Gross
With recent sanity checks for topology information added, there are now warnings issued for APs when running as a Xen PV guest: [Firmware Bug]: CPU 1: APIC ID mismatch. CPUID: 0x0000 APIC: 0x0001 This is due to the initial APIC ID obtained via CPUID for PV guests is always 0. Avoid the warnings by synthesizing the CPUID data to contain the same initial APIC ID as xen_pv_smp_config() is using for registering the APIC IDs of all CPUs.

2024-05-02bpf: Missing trailing slash in tools/testing/selftests/bpf/MakefileJose E. Marchesi
tools/lib/bpf/Makefile assumes that the patch in OUTPUT is a directory and that it includes a trailing slash. This seems to be a common expectation for OUTPUT among all the Makefiles. In the rule for runqslower in tools/testing/selftests/bpf/Makefile the variable BPFTOOL_OUTPUT is set to a directory name that lacks a trailing slash. This results in a malformed BPF_HELPER_DEFS being defined in lib/bpf/Makefile. This problem becomes evident when a file like tools/lib/bpf/bpf_tracing.h gets updated. This patch fixes the problem by adding the missing slash in the value for BPFTOOL_OUTPUT in the $(OUTPUT)/runqslower rule. Regtested by running selftests in bpf-next master and building samples/bpf programs. Signed-off-by: Jose E.

2024-05-02drm/xe/display: Fix ADL-N detectionLucas De Marchi
Contrary to i915, in xe ADL-N is kept as a different platform, not a subplatform of ADL-P. Since the display side doesn't need to differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called, just fixup the compat header to check for both P and N. Moving ADL-N to be a subplatform would be more complex as the firmware loading in xe only handles platforms, not subplatforms, as going forward the direction is to check on IP version rather than platforms/subplatforms. Fix warning when initializing display: xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH ------------[ cut here ]------------ xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P)) And wrong paths being taken on the display side.

2024-05-02docs: stable-kernel-rules: create special tag to flag 'no backporting'Thorsten Leemhuis
Document a new variant of the stable tag developers can use to make the stable team's tools ignore a change[1]. That way developers can use 'Fixes:' tags without fearing the changes might be backported in semi-automatic fashion. Such concerns are the reason why some developers deliberately omit the 'Fixes:' tag in changes[2] -- which somewhat undermines the reason for the existence of that tag and might be unwise in the long term[3].

2024-05-02x86/xen/smp_pv: Register the boot CPU APIC properlyThomas Gleixner
The topology core expects the boot APIC to be registered from earhy APIC detection first and then again when the firmware tables are evaluated. This is used for detecting the real BSP CPU on a kexec kernel. The recent conversion of XEN/PV to register fake APIC IDs failed to register the boot CPU APIC correctly as it only registers it once. This causes the BSP detection mechanism to trigger wrongly: CPU topo: Boot CPU APIC ID not the first enumerated APIC ID: 0 > 1 Additionally this results in one CPU being ignored. Register the boot CPU APIC twice so that the XEN/PV fake enumeration behaves like real firmware.

2024-05-02string: Add additional __realloc_size() annotations for "dup" helpersKees Cook
Several other "dup"-style interfaces could use the __realloc_size() attribute. (As a reminder to myself and others: "realloc" is used here instead of "alloc" because the "alloc_size" attribute implies that the memory contents are uninitialized. Since we're copying contents into the resulting allocation, it must use "realloc_size" to avoid confusing the compiler's optimization passes.) Add KUnit test coverage where possible. (KUnit still does not have the ability to manipulate userspace memory.)

Michael Chan says: ==================== bnxt_en: Updates for net-next The first patch converts the sw_stats field in the completion ring structure to a pointer. This allows the group of completion rings using the same MSIX to share the same sw_stats structure. Prior to this, the correct completion ring must be used to count packets. The next four patches remove the RTNL lock when calling the RoCE driver for asynchronous stop and start during error recovery and firmware reset. The RTNL ilock is replaced with a private mutex used to synchronize RoCE register, unregister, stop, and start. The last patch adds VF PCI IDs for the 5760X chips. v2: Dropped patch #1 from v1.

2024-05-02bnxt_en: Optimize recovery path ULP locking in the driverKalesh AP
In the error recovery path (AER, firmware recovery, etc), the driver notifies the RoCE driver via ULP_STOP before the reset and via ULP_START after the reset, all under RTNL_LOCK. The RoCE driver can take a long time if there are a lot of QPs to destroy, so it is not ideal to hold the global RTNL lock. Rely on the new en_dev_lock mutex instead for ULP_STOP and ULP_START. For the most part, we move the ULP_STOP call before we take the RTNL lock and move the ULP_START after RTNL unlock. Note that SRIOV re-enablement must be done after ULP_START or RoCE on the VFs will not resume properly after reset. The one scenario in bnxt_hwrm_if_change() where the RTNL lock is already taken in the .ndo_open() context requires the ULP restart to be deferred to the bnxt_sp_task() workqueue.

2024-05-02bnxt_en: share NQ ring sw_stats memory with subringsEdwin Peer
On P5_PLUS chips and later, the NQ rings have subrings for RX and TX completions respectively. These subrings are passed to the poll function instead of the base NQ, but each ring carries its own copy of the software ring statistics. For stats to be conveniently accessible in __bnxt_poll_work(), the statistics memory should either be shared between the NQ and its subrings or the subrings need to be included in the ethtool stats aggregation logic. This patch opts for the former, because it's more efficient and less confusing having the software statistics for a ring exist in a single place. Before this patch, the counter will not be displayed if the "wrong" cpr->sw_stats was used to increment a counter.

For SLAB the kmalloc caches needed to be created in ascending sizes in order. However, the constraint is not necessary anymore because SLAB has been removed and SLUB doesn't need to comply with the constraint. Thus, kmalloc 96 and 192 caches can be created after the other size kmalloc caches are created instead of checking every time to find their order to be created. Also, this change could prevent engineers from being confused by the removed constraint.

2024-05-02swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=yWill Deacon
Using restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction with dynamic SWIOTLB (CONFIG_SWIOTLB_DYNAMIC=y) leads to the following crash when initialising the restricted pools at boot-time: | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 | Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP | pc : rmem_swiotlb_device_init+0xfc/0x1ec | lr : rmem_swiotlb_device_init+0xf0/0x1ec | Call trace: | rmem_swiotlb_device_init+0xfc/0x1ec | of_reserved_mem_device_init_by_idx+0x18c/0x238 | of_dma_configure_id+0x31c/0x33c | platform_dma_configure+0x34/0x80 faddr2line reveals that the crash is in the list validation code: include/linux/list.h:83 include/linux/rculist.h:79 include/linux/rculist.h:106 kernel/dma/swiotlb.c:306 kernel/dma/swiotlb.c:1695 because add_mem_pool() is trying to list_add_rcu() to a NULL 'mem->pools'. Fix the crash by initialising the 'mem->pools' list_head in rmem_swiotlb_device_init() before calling add_mem_pool().
