[PATCH AUTOSEL 4.19 1/5] scsi: lpfc: Update lpfc_ramp_down_queue_handler() logic

by Sasha Levin

From: Justin Tee <justin.tee(a)broadcom.com> [ Upstream commit bb011631435c705cdeddca68d5c85fd40a4320f9 ] Typically when an out of resource CQE status is detected, the lpfc_ramp_down_queue_handler() logic is called to help reduce I/O load by reducing an sdev's queue_depth. However, the current lpfc_rampdown_queue_depth() logic does not help reduce queue_depth. num_cmd_success is never updated and is always zero, which means new_queue_depth will always be set to sdev->queue_depth. So, new_queue_depth = sdev->queue_depth - new_queue_depth always sets new_queue_depth to zero. And, scsi_change_queue_depth(sdev, 0) is essentially a no-op. Change the lpfc_ramp_down_queue_handler() logic to set new_queue_depth equal to sdev->queue_depth subtracted from number of times num_rsrc_err was incremented. If num_rsrc_err is >= sdev->queue_depth, then set new_queue_depth equal to 1. Eventually, the frequency of Good_Status frames will signal SCSI upper layer to auto increase the queue_depth back to the driver default of 64 via scsi_handle_queue_ramp_up().

[PATCH AUTOSEL 5.15 01/10] scsi: lpfc: Move NPIV's transport unregistration to after resource clean up

by Sasha Levin

From: Justin Tee <justin.tee(a)broadcom.com> [ Upstream commit 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c ] There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.

Regression in kernel 6.8.2 fails in various ways (USB, BT, ...)

by Norbert Preining

Hi all (please cc) I am running Arch Linux on a Lenovo X1 Carbon Gen 10. Tests are made with uptodate system, and besides the kernel no difference. The kernels are as distributed by Arch, but if necessary I can compile locally. Arch Linux kernel 6.8.1 works without any problems. Upgrading to 6.8.2 breaks a lot of things: * Plugging in my Yubikey C does not trigger any reaction (as a consequence scdaemon hangs) * sending of bluetooth firmware data fails with Oops (see below) * shutdown hangs and does not turn off the computer I can repeat this behaviour on every reboot into 6.8.2. I have dmesg/journalctl -b for both kernels collected, if required, I can send them. I checked the diffs but nothing really did stand out.

OK, so the reason the bad patch got pulled in is because it's a precursor of this fixes tagged backport: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… Which is presumably the other patch you had to back out to fix the issue. The problem is that Mike's series updating and then removing scsi_execute() went into the tree as one series, so no-one notice the first patch had this bug because the buggy routine got removed at the end of the series. This also means there's nothing to fix and backport in upstream. The bug is also more widely spread than simply domain validation, because every use of scsi_execute in the current stable tree will trip this. I'm not sure what the best fix is. I can certainly come up with a one line fix for stable adding the missing length in the #define, but it can't come from upstream as stated above. We could back the two patches out then do a stable specific fix for the UAS problem (I don't think we can leave the UAS patch backed out because the problem was pretty serious). What does stable want to do? James

[PATCH for 6.1.y] nvme: fix miss command type check

by Tokunori Ikegami

From: "min15.li" <min15.li(a)samsung.com> commit 31a5978243d24d77be4bacca56c78a0fbc43b00d upstream. In the function nvme_passthru_end(), only the value of the command opcode is checked, without checking the command type (IO command or Admin command). When we send a Dataset Management command (The opcode of the Dataset Management command is the same as the Set Feature command), kernel thinks it is a set feature command, then sets the controller's keep alive interval, and calls nvme_keep_alive_work().

[OOPS][STABLE] NULL pointer dereferenced with Linux 6.8.4

by Chris Rankin

Hi, Just noticed this OOPS in my vanilla 6.8.4 kernel dmesg log. The USB device here is an optical drive, although oddly I wasn't unplugging it at the time. I was actually remounting it as a different user: $ udisksctl unmount -b /dev/sr1 <SWITCH USER> $ udisksctl mount -b /dev/sr1 [ 7737.972588] usb 2-4: USB disconnect, device number 3 [ 7743.332135] BUG: kernel NULL pointer dereference, address: 0000000000000370 [ 7743.337805] #PF: supervisor write access in kernel mode [ 7743.341730] #PF: error_code(0x0002) - not-present page [ 7743.345569] PGD 0 P4D 0 [ 7743.346830] Oops: 0002 [#1] PREEMPT SMP PTI [ 7743.349711] CPU: 4 PID: 27870 Comm: kworker/4:0 Tainted: G I 6.8.4 #1 [ 7743.356237] Hardware name: Gigabyte Technology Co., Ltd.

[PATCH v3] scsi: sg: Avoid race in error handling & drop bogus warn

by Alexander Wetzel

commit 27f58c04a8f4 ("scsi: sg: Avoid sg device teardown race") introduced an incorrect WARN_ON_ONCE() and missed a sequence where sg_device_destroy() was used after scsi_device_put(). sg_device_destroy() is accessing the parent scsi_device request_queue which will already be set to NULL when the preceding call to scsi_device_put() removed the last reference to the parent scsi_device. Drop the incorrect WARN_ON_ONCE() - allowing more than one concurrent access to the sg device - and make sure sg_device_destroy() is not used after scsi_device_put() in the error handling.

[PATCH 01/12] drm/client: Fully protect modes[] with dev->mode_config.mutex

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> The modes[] array contains pointers to modes on the connectors' mode lists, which are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory.

[PATCH] scsi: core: Fix handling of SCMD_FAIL_IF_RECOVERING

by Bart Van Assche

[PATCH] ext4: fix i_data_sem unlock order in ext4_ind_migrate()

by Mikhail Ukhin

Fuzzing reports a possible deadlock in jbd2_log_wait_commit. The problem occurs in ext4_ind_migrate due to an incorrect order of unlocking of the journal and write semaphores - the order of unlocking must be the reverse of the order of locking.

[merged mm-hotfixes-stable] x86-mm-pat-fix-vm_pat-handling-in-cow-mappings.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: x86/mm/pat: fix VM_PAT handling in COW mappings has been removed from the -mm tree. Its filename was x86-mm-pat-fix-vm_pat-handling-in-cow-mappings.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: x86/mm/pat: fix VM_PAT handling in COW mappings Date: Wed, 3 Apr 2024 23:21:30 +0200 PAT handling won't do the right thing in COW mappings: the first PTE (or, in fact, all PTEs) can be replaced during write faults to point at anon folios. Reliably recovering the correct PFN and cachemode using follow_phys() from PTEs will not work in COW mappings. Using follow_phys(), we might just get the address+protection of the anon folio (which is very wrong), or fail on swap/nonswap entries, failing follow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and track_pfn_copy(), not properly calling free_pfn_range(). In free_pfn_range(), we either wouldn't call memtype_free() or would call it with the wrong range, possibly leaking memory. To fix that, let's update follow_phys() to refuse returning anon folios, and fallback to using the stored PFN inside vma->vm_pgoff for COW mappings if we run into that. We will now properly handle untrack_pfn() with COW mappings, where we don't need the cachemode. We'll have to fail fork()->track_pfn_copy() if the first page was replaced by an anon folio, though: we'd have to store the cachemode in the VMA to make this work, likely growing the VMA size. For now, lets keep it simple and let track_pfn_copy() just fail in that case: it would have failed in the past with swap/nonswap entries already, and it would have done the wrong thing with anon folios. Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn(): <--- C reproducer ---> #include <stdio.h> #include <sys/mman.h> #include <unistd.h> #include <liburing.h> int main(void) { struct io_uring_params p = {}; int ring_fd; size_t size; char *map; ring_fd = io_uring_setup(1, &p); if (ring_fd < 0) { perror("io_uring_setup"); return 1; } size = p.sq_off.array + p.sq_entries * sizeof(unsigned); /* Map the submission queue ring MAP_PRIVATE */ map = mmap(0, size, PROT_READ | PROT_WRITE, MAP_PRIVATE, ring_fd, IORING_OFF_SQ_RING); if (map == MAP_FAILED) { perror("mmap"); return 1; } /* We have at least one page.

Its filename was mm-secretmem-fix-gup-fast-succeeding-on-secretmem-folios.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/secretmem: fix GUP-fast succeeding on secretmem folios Date: Tue, 26 Mar 2024 15:32:08 +0100 folio_is_secretmem() currently relies on secretmem folios being LRU folios, to save some cycles. However, folios might reside in a folio batch without the LRU flag set, or temporarily have their LRU flag cleared. Consequently, the LRU flag is unreliable for this purpose. In particular, this is the case when secretmem_fault() allocates a fresh page and calls filemap_add_folio()->folio_add_lru(). The folio might be added to the per-cpu folio batch and won't get the LRU flag set until the batch was drained using e.g., lru_add_drain(). Consequently, folio_is_secretmem() might not detect secretmem folios and GUP-fast can succeed in grabbing a secretmem folio, crashing the kernel when we would later try reading/writing to the folio, because the folio has been unmapped from the directmap. Fix it by removing that unreliable check.

As reported by Christoph, this is "surprising" because the counter might become greater than MPTcpExtMPCapableSYNRX. MPTcpExtMPCapableFallbackACK counter's name suggests it should only be incremented when a connection was seen using MPTCP options, then a fallback to TCP has been done.

[PATCH] ASoC: qcom: Fix out of bounds access

by Mikhail Kobuk

Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()). Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH v2 1/2] phy: tegra: xusb: Add API to retrieve the port number of phy

by Wayne Chang

This patch introduces a new API, tegra_xusb_padctl_get_port_number, to the Tegra XUSB Pad Controller driver. This API is used to identify the USB port that is associated with a given PHY. The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input and returns the corresponding port number. If the PHY pointer is invalid, it returns -ENODEV.

E.g., for multi-kprobes and multi-uprobes, link is used to fetch BPF cookie values. Because of this runtime dependency, when bpf_link refcnt drops to zero there could still be active BPF programs running accessing link data. This patch adds generic support to defer bpf_link dealloc callback to after RCU GP, if requested. This is done by exposing two different deallocation callbacks, one synchronous and one deferred. If deferred one is provided, bpf_link_free() will schedule dealloc_deferred() callback to happen after RCU GP. BPF is using two flavors of RCU: "classic" non-sleepable one and RCU tasks trace one. The latter is used when sleepable BPF programs are used. bpf_link_free() accommodates that by checking underlying BPF program's sleepable flag, and goes either through normal RCU GP only for non-sleepable, or through RCU tasks trace GP *and* then normal RCU GP (taking into account rcu_trace_implies_rcu_gp() optimization), if BPF program is sleepable.

ivpu_device->context_xa is locked both in kernel thread and IRQ context.

As reported by Christoph, this is "surprising" because the counter might become greater than MPTcpExtMPCapableSYNRX. MPTcpExtMPCapableFallbackACK counter's name suggests it should only be incremented when a connection was seen using MPTCP options, then a fallback to TCP has been done. Let's do that by incrementing it when the subflow context of an inbound MPC connection attempt is dropped. Also, update mptcp_connect.sh kselftest, to ensure that the above MIB does not increment in case a pure TCP client connects to a MPTCP server.

[PATCH] perf/x86/intel/ds: Fix non 0 retire latency on Raptorlake

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> A non-0 retire latency can be observed on a Raptorlake which doesn't support the retire latency feature. By design, the retire latency shares the PERF_SAMPLE_WEIGHT_STRUCT sample type with other types of latency. That could avoid adding too many different sample types to support all kinds of latency. For the machine which doesn't support some kind of latency, 0 should be returned. Perf doesn’t clear/init all the fields of a sample data for the sake of performance. It expects the later perf_{prepare,output}_sample() to update the uninitialized field. However, the current implementation doesn't touch the field of the retire latency if the feature is not supported. The memory garbage is dumped into the perf data. Clear the retire latency if the feature is not supported.

That is, the alternative() in UNTRAIN_RET will patch in the CALL to srso_alias_untrain_ret() directly. However, even if commit e7c25c441e9e ("x86/cpu: Cleanup the untrain mess") meant well in trying to clean up the situation, due to micro- architectural reasons, the untraining routine srso_alias_untrain_ret() must be the target of a CALL instruction and not of a JMP instruction as it is done now. Reshuffle the alternative macros to accomplish that.

[PATCH] x86/mm/ident_map: Use full gbpages in identity maps except on UV platform.

by Steve Wahl

Some systems have ACPI tables that don't include everything that needs to be mapped for a successful kexec. These systems rely on identity maps that include the full gigabyte surrounding any smaller region requested for kexec success. Without this, they fail to kexec and end up doing a full firmware reboot. So, reduce the use of GB pages only on systems where this is known to be necessary (specifically, UV systems).

In certain situation when busy-loop is enabled together with adaptive coalescing, the driver occasionally misses that there are outstanding descriptors to clean when exiting busy poll. Try to catch the remaining work by triggering a software interrupt when exiting busy poll. No extra interrupts will be generated when busy polling is not used. The issue was found when running sockperf ping-pong tcp test with adaptive coalescing and busy poll enabled (50 as value busy_pool and busy_read sysctl knobs) and results in huge latency spikes with more than 100000us. The fix is inspired from the ice driver and do the following: 1) During napi poll exit in case of busy-poll (napo_complete_done() returns false) this is recorded to q_vector that we were in busy loop. 2) Extends i40e_buildreg_itr() to be able to add an enforced software interrupt into built value 2) In i40e_update_enable_itr() enforces a software interrupt trigger if we are exiting busy poll to catch any pending clean-ups 3) Reuses unused 3rd ITR (interrupt throttle) index and set it to 20K interrupts per second to limit the number of these sw interrupts.

In certain situation when busy-loop is enabled together with adaptive coalescing, the driver occasionally misses that there are outstanding descriptors to clean when exiting busy poll. Try to catch the remaining work by triggering a software interrupt when exiting busy poll. No extra interrupts will be generated when busy polling is not used. The issue was found when running sockperf ping-pong tcp test with adaptive coalescing and busy poll enabled (50 as value busy_pool and busy_read sysctl knobs) and results in huge latency spikes with more than 100000us. The fix is inspired from the ice driver and do the following: 1) During napi poll exit in case of busy-poll (napo_complete_done() returns false) this is recorded to q_vector that we were in busy loop. 2) Extends i40e_buildreg_itr() to be able to add an enforced software interrupt into built value 2) In i40e_update_enable_itr() enforces a software interrupt trigger if we are exiting busy poll to catch any pending clean-ups 3) Reuses unused 3rd ITR (interrupt throttle) index and set it to 20K interrupts per second to limit the number of these sw interrupts.

In certain situation when busy-loop is enabled together with adaptive coalescing, the driver occasionally misses that there are outstanding descriptors to clean when exiting busy poll. Try to catch the remaining work by triggering a software interrupt when exiting busy poll. No extra interrupts will be generated when busy polling is not used. The issue was found when running sockperf ping-pong tcp test with adaptive coalescing and busy poll enabled (50 as value busy_pool and busy_read sysctl knobs) and results in huge latency spikes with more than 100000us. The fix is inspired from the ice driver and do the following: 1) During napi poll exit in case of busy-poll (napo_complete_done() returns false) this is recorded to q_vector that we were in busy loop. 2) Extends i40e_buildreg_itr() to be able to add an enforced software interrupt into built value 2) In i40e_update_enable_itr() enforces a software interrupt trigger if we are exiting busy poll to catch any pending clean-ups 3) Reuses unused 3rd ITR (interrupt throttle) index and set it to 20K interrupts per second to limit the number of these sw interrupts.

It is suspected to be caused by initiating PHY transactions before the interface settles. Separating this configuration from the ULP enabling flow and moving it to the shutdown function allows enough time for the interface to settle and avoids adding a delay.
