The ondisk AGF has a higher LSN than the recovered log item. xlog_recover_buf_commit_pass2 reads the buffer, compares the LSNs, and decides to skip replay because the ondisk buffer appears to be newer. Unfortunately, the ondisk buffer is corrupt, but recovery just read the buffer with no buffer ops specified: error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno, buf_f->blf_len, buf_flags, &bp, NULL); Skipping the buffer leaves its contents in memory unverified. This sets us up for a kernel crash because xfs_refcount_recover_cow_leftovers reads the buffer (which is still around in XBF_DONE state, so no read verification) and creates a refcountbt cursor of height 32. This is impossible so we run off the end of the cursor object and crash. Fix this by invoking the verifier on all skipped buffers and aborting log recovery if the ondisk buffer is corrupt. It might be smarter to force replay the log item atop the buffer and then see if it'll pass the write verifier (like ext4 does) but for now let's go with the conservative option where we stop immediately.

My theory is that the controller: - first sets the IFLG in control register - then updates the status register - then raises an interrupt This may sometime cause weird bugs when in atomic mode, since in this mode we do not wait for an interrupt, but instead we poll the control register for IFLG and read status register immediately after. I encountered -ENXIO from mv64xxx_i2c_fsm() due to this issue when using this driver in atomic mode. Note that I've only seen this issue on Armada 385, I don't know whether other SOCs with this controller are also affected. Also note that this fix has been in U-Boot for over 4 years [1] without anybody complaining, so it should not cause regressions.

At mt8195_afe_deinit_clock() located at mt8195_afe_pcm_dev_remove(), mt8195_audsys_clk_unregister() was called. However, there was an issue with the order in which these functions were called. Specifically, the remove callback of platform_driver was called before devres released the resource, resulting in a use-after-free issue during remove time. At probe time, the order of calls was: 1. mt8195_audsys_clk_register 2. afe_priv->clk = devm_kcalloc 3. afe_priv->clk[i] = devm_clk_get At remove time, the order of calls was: 1. mt8195_audsys_clk_unregister 3. free afe_priv->clk[i] 2. free afe_priv->clk To resolve the problem, we can utilize devm_add_action_or_reset() in mt8195_audsys_clk_register() so that the remove order can be changed to 3->2->1.

However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void.

The cpufreq table in sc7180.dtsi includes the superset of all CPU frequencies. The "qcom-cpufreq-hw" driver in Linux shows that we can dynamically detect which frequencies are actually available on the currently running CPU and then we can just enable those ones. The GPU is similarly dynamic. The nvmem has a fuse in it (see "gpu_speed_bin" in sc7180.dtsi) that the GPU driver can use to figure out which frequencies to enable. There is one part, however, that is not so dynamic. The way SDRAM frequency works in sc7180 is that it's tied to cpufreq. At the busiest cpufreq operating points we'll pick the top supported SDRAM frequency. They ramp down together. For the "pro" SKU of sc7180, we only enable one extra cpufreq step. That extra cpufreq step runs SDRAM at the same speed as the step below. Thus, for normal and pro things are OK. There is no sc7180-pro device tree snippet. For the "lite" SKU if sc7180, however, things aren't so easy. The "lite" SKU drops 3 cpufreq entries but can still run SDRAM at max frequency. That messed things up with the whole scheme. This is why we added the "sc7180-lite" fragment in commit 8fd01e01fd6f ("arm64: dts: qcom: sc7180-lite: Tweak DDR/L3 scaling on SC7180-lite"). When the lite scheme came about, it was agreed that the WiFi SKUs of lazor would _always_ be "lite" and would, in fact, be the only "lite" devices. Unfortunately, this decision changed and folks didn't realize that it would be a problem. Specifically, some later lazor WiFi-only devices were built with "pro" CPUs. Building WiFi-only lazor with "pro" CPUs isn't the end of the world. The SDRAM will ramp up a little sooner than it otherwise would, but aside from a small power hit things work OK. One problem, though, is that the SDRAM scaling becomes a bit quirky. Specifically, with the current tables we'll max out SDRAM frequency at 2.1GHz but then _lower_ it at 2.2GHz / 2.3GHz only to raise it back to max for 2.4GHz and 2.55GHz. Let's at least fix this so that the SDRAM frequency doesn't go down in that quirky way. On true "lite" SKUs this change will be a no-op because the operating points we're touching are disabled. This change is only useful when a board that thinks it has a "lite" CPU actually has a "normal" or "pro" one stuffed.

When hcd->localmem_pool is non-null, localmem_pool is used to allocate DMA memory. In this case, the dma address will be properly returned (in dma_handle), and dma_mmap_coherent should be used to map this memory into the user space. However, the current implementation uses pfn_remap_range, which is supposed to map normal pages. Instead of repeating the logic in the memory allocation function, this patch introduces a more robust solution. Here, the type of allocated memory is checked by testing whether dma_handle is properly set. If dma_handle is properly returned, it means some DMA pages are allocated and dma_mmap_coherent should be used to map them. Otherwise, normal pages are allocated and pfn_remap_range should be called. This ensures that the correct mmap functions are used consistently, independently with logic details that determine which type of memory gets allocated.

The current implementation of usbdev_mmap uses usb_alloc_coherent to allocate memory pages that will later be mapped into the user space. Meanwhile, usb_alloc_coherent employs three different methods to allocate memory, as outlined below: * If hcd->localmem_pool is non-null, it uses gen_pool_dma_alloc to allocate memory; * If DMA is not available, it uses kmalloc to allocate memory; * Otherwise, it uses dma_alloc_coherent. However, it should be noted that gen_pool_dma_alloc does not guarantee that the resulting memory will be page-aligned. Furthermore, trying to map slab pages (i.e., memory allocated by kmalloc) into the user space is not resonable and can lead to problems, such as a type confusion bug when PAGE_TABLE_CHECK=y [1]. To address these issues, this patch introduces hcd_alloc_coherent_pages, which addresses the above two problems. Specifically, hcd_alloc_coherent_pages uses gen_pool_dma_alloc_align instead of gen_pool_dma_alloc to ensure that the memory is page-aligned. To replace kmalloc, hcd_alloc_coherent_pages directly allocates pages by calling __get_free_pages.

This patch addresses an issue within the j1939_sk_send_loop_abort() function in the j1939/socket.c file, specifically in the context of Transport Protocol (TP) sessions. Without this patch, when a TP session is initiated and a Clear To Send (CTS) frame is received from the remote side requesting one data packet, the kernel dispatches the first Data Transport (DT) frame and then waits for the next CTS. If the remote side doesn't respond with another CTS, the kernel aborts due to a timeout. This leads to the user-space receiving an EPOLLERR on the socket, and the socket becomes active. However, when trying to read the error queue from the socket with sock.recvmsg(, , socket.MSG_ERRQUEUE), it returns -EAGAIN, given that the socket is non-blocking. This situation results in an infinite loop: the user-space repeatedly calls epoll(), epoll() returns the socket file descriptor with EPOLLERR, but the socket then blocks on the recv() of ERRQUEUE. This patch introduces an additional check for the J1939_SOCK_ERRQUEUE flag within the j1939_sk_send_loop_abort() function. If the flag is set, it indicates that the application has subscribed to receive error queue messages. In such cases, the kernel can communicate the current transfer state via the error queue. This allows for the function to return early, preventing the unnecessary setting of the socket into an error state, and breaking the infinite loop. It is crucial to note that a socket error is only needed if the application isn't using the error queue, as, without it, the application wouldn't be aware of transfer issues.

Mainly because they are not fully expecting to handle signals, but also cutting the intended test runtimes short due signal_pending() now returning true (via __igt_timeout), which therefore breaks both the patterns of: kthread_run() ..sleep for igt_timeout_ms to allow test to exercise stuff.. kthread_stop() And check for errors recorded in the thread. And also: Main thread | Test thread ---------------+------------------------------ kthread_run() | kthread_stop() | do stuff until __igt_timeout | -- exits early due signal -- Where this kthread_stop() was assume would have a "join" semantics, which it would have had if not the new signal assertion issue. To recap, threads are now likely to catch a previously impossible ERESTARTSYS or EINTR, marking the test as failed, or have a pointlessly short run time. To work around this start using kthread_work(er) API which provides an explicit way of waiting for threads to exit. And for cases where parent controls the test duration we add explicit signaling which threads will now use instead of relying on kthread_should_stop().

[ Upstream commit a2f4c143d76b1a47c91ef9bc46907116b111da0b ] A remote DoS vulnerability of RPL Source Routing is assigned CVE-2023-2156. The Source Routing Header (SRH) has the following format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Next Header | Hdr Ext Len | Routing Type | Segments Left | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | CmprI | CmprE | Pad | Reserved | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | . . . Addresses[1..n] . . . | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ The originator of an SRH places the first hop's IPv6 address in the IPv6 header's IPv6 Destination Address and the second hop's IPv6 address as the first address in Addresses[1..n]. The CmprI and CmprE fields indicate the number of prefix octets that are shared with the IPv6 Destination Address. When CmprI or CmprE is not 0, Addresses[1..n] are compressed as follows: 1..n-1 : (16 - CmprI) bytes n : (16 - CmprE) bytes Segments Left indicates the number of route segments remaining. When the value is not zero, the SRH is forwarded to the next hop. Its address is extracted from Addresses[n - Segment Left + 1] and swapped with IPv6 Destination Address. When Segment Left is greater than or equal to 2, the size of SRH is not changed because Addresses[1..n-1] are decompressed and recompressed with CmprI. OTOH, when Segment Left changes from 1 to 0, the new SRH could have a different size because Addresses[1..n-1] are decompressed with CmprI and recompressed with CmprE. Let's say CmprI is 15 and CmprE is 0. When we receive SRH with Segment Left >= 2, Addresses[1..n-1] have 1 byte for each, and Addresses[n] has 16 bytes. When Segment Left is 1, Addresses[1..n-1] is decompressed to 16 bytes and not recompressed. Finally, the new SRH will need more room in the header, and the size is (16 - 1) * (n - 1) bytes. Here the max value of n is 255 as Segment Left is u8, so in the worst case, we have to allocate 3825 bytes in the skb headroom. However, now we only allocate a small fixed buffer that is IPV6_RPL_SRH_WORST_SWAP_SIZE (16 + 7 bytes). If the decompressed size overflows the room, skb_push() hits BUG() below [0]. Instead of allocating the fixed buffer for every packet, let's allocate enough headroom only when we receive SRH with Segment Left 1.

For example, l2sock_shutdown acquires these locks in the order: mutex_lock(&conn->chan_lock) l2cap_chan_lock(chan) However, l2cap_disconnect_req acquires chan->lock in l2cap_get_chan_by_scid first and then acquires conn->chan_lock before calling l2cap_chan_del. This means that these locks are acquired in unexpected order, which leads to potential deadlock: l2cap_chan_lock(c) mutex_lock(&conn->chan_lock) This patch releases chan->lock before acquiring the conn_chan_lock to avoid the potential deadlock.

That way they do not change state in case one of the resources is not available yet and probe deferral (-EPROBE_DEFER) is necessary. This is particularly important for DMA channels and IOMMUs which are not enforced by fw_devlink yet (unless you use fw_devlink.strict=1). spi-qup does this in the wrong order, the clocks are enabled and disabled again when the DMA channels are not available yet. This causes issues in some cases: On most SoCs one of the SPI QUP clocks is shared with the UART controller. When using earlycon UART is actively used during boot but might not have probed yet, usually for the same reason (waiting for the DMA controller). In this case, the brief enable/disable cycle ends up gating the clock and further UART console output will halt the system completely. Avoid this by requesting the DMA channels before changing the clock state.

However, this has lead to some problems: In some instances, the event notifier function called inside this completion workqueue takes a non-negligible amount of time to execute. One such example is the battery event handling code (surface_battery.c), which can result in a full battery information refresh, involving further synchronous communication with the EC inside the event handler. This is made worse if the communication fails spuriously, generally incurring a multi-second timeout. Since the event completions are run strictly non-parallel, this blocks other events from being propagated to the respective subsystems. This becomes especially noticeable for keyboard and touchpad input, which also funnel their events through this system. Here, users have reported occasional multi-second "freezes". Note, however, that the event handling system was never intended to run purely sequentially. Instead, we have one work struct per EC/SAM subsystem, processing the event queue for that subsystem. These work structs were intended to run in parallel, allowing sequential processing of work items for each subsystem but parallel processing of work items across subsystems. The only restriction to this is the way the workqueue is created. Therefore, replace create_workqueue() with alloc_workqueue() and do not restrict the maximum number of parallel work items to be executed on that queue, resolving any cross-subsystem blockage.

To prepare for removal of i40e_status, change the variables from i40e_status to int. This eases the transition when values are changed to return standard int error codes over enum i40e_status. As such changes often also change variable orders, a cleanup is also applied here to make variables conform to RCT and some lines are also reformatted where applicable.

This driver is for fairly obscure hardware, and has only seen random drive-by changes after the maintainer stopped working on it in 2005 (about a year and a half after it was introduced). It has some "interesting" block layer interactions, so let's just drop it unless anyone complains.

The problem in libata is that it contains a single enum definition for lots of unrelated constants, some of which are large positive (unsigned) integers like 0xffffffff, while others like (1<<31) are interpreted as negative integers, and this forces the enum type to become 64 bit wide even though most constants would still fit into a signed 32-bit 'int'. Fix this by changing the entire enum definition to use BIT(x) in place of (1< Cc: linux-ide@vger.kernel.org Cc: Damien Le Moal Cc: stable@vger.kernel.org Cc: Randy Dunlap Signed-off-by: Arnd Bergmann Tested-by: Luis Machado Signed-off-by: Damien Le Moal [ Modified to account for slight differences in the enum contents in the 5.15.y tree. ] Signed-off-by: Paul Barker Signed-off-by: Greg Kroah-Hartman
