As I have been maintaining Debian's sh4 port since 2014, I am interested to keep the architecture alive.

5e98e91 Linus Torvalds 12 February 2023, 21:52:17 UTC Merge tag 'trace-v6.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: "Fix showing of TASK_COMM_LEN instead of its value The TASK_COMM_LEN was converted from a macro into an enum so that BTF would have access to it. But this unfortunately caused TASK_COMM_LEN to display in the format fields of trace events, as they are created by the TRACE_EVENT() macro and such, macros convert to their values, where as enums do not. To handle this, instead of using the field itself to be display, save the value of the array size as another field in the trace_event_fields structure, and use that instead. Not only does this fix the issue, but also converts the other trace events that have this same problem (but were not breaking tooling). With this change, the original work around b3bc8547d3be6 ("tracing: Have TRACE_DEFINE_ENUM affect trace event types as well") could be reverted (but that should be done in the merge window)" * tag 'trace-v6.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix TASK_COMM_LEN in trace event format file 12 February 2023, 21:52:17 UTC

462a8e0 David Chen 09 February 2023, 17:48:28 UTC Fix page corruption caused by racy check in __free_pages When we upgraded our kernel, we started seeing some page corruption like the following consistently: BUG: Bad page state in process ganesha.nfsd pfn:1304ca page:0000000022261c55 refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x1304ca flags: 0x17ffffc0000000() raw: 0017ffffc0000000 ffff8a513ffd4c98 ffffeee24b35ec08 0000000000000000 raw: 0000000000000000 0000000000000001 00000000ffffff7f 0000000000000000 page dumped because: nonzero mapcount CPU: 0 PID: 15567 Comm: ganesha.nfsd Kdump: loaded Tainted: P B O 5.10.158-1.nutanix.20221209.el7.x86_64 #1 Hardware name: VMware, Inc.

Sometimes, it would also show up as corruption in the free list pointer and cause crashes. After bisecting the issue, we found the issue started from commit e320d3012d25 ("mm/page_alloc.c: fix freeing non-compound pages"): if (put_page_testzero(page)) free_the_page(page, order); else if (!PageHead(page)) while (order-- > 0) free_the_page(page + (1 << order), order); So the problem is the check PageHead is racy because at this point we already dropped our reference to the page. So even if we came in with compound page, the page can already be freed and PageHead can return false and we will end up freeing all the tail pages causing double free.

b6c7abd Yafang Shao 12 February 2023, 15:13:03 UTC tracing: Fix TASK_COMM_LEN in trace event format file After commit 3087c61ed2c4 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN"), the content of the format file under /sys/kernel/tracing/events/task/task_newtask was changed from field:char comm[16]; offset:12; size:16; signed:0; to field:char comm[TASK_COMM_LEN]; offset:12; size:16; signed:0; John reported that this change breaks older versions of perfetto. Then Mathieu pointed out that this behavioral change was caused by the use of __stringify(_len), which happens to work on macros, but not on enum labels. And he also gave the suggestion on how to fix it: :One possible solution to make this more robust would be to extend :struct trace_event_fields with one more field that indicates the length :of an array as an actual integer, without storing it in its stringified :form in the type, and do the formatting in f_show where it belongs. The result as follows after this change, $ cat /sys/kernel/tracing/events/task/task_newtask/format field:char comm[16]; offset:12; size:16; signed:0; Link: https://lore.kernel.org/lkml/Y+QaZtz55LIirsUO@google.com/ Link: https://lore.kernel.org/linux-trace-kernel/20230210155921.4610-1-laoar.shao@gmail.com/ Link: https://lore.kernel.org/linux-trace-kernel/20230212151303.12353-1-laoar.shao@gmail.com Cc: stable@vger.kernel.org Cc: Alexei Starovoitov <alexei.starovoitov@gmail.com> Cc: Kajetan Puchalski <kajetan.puchalski@arm.com> CC: Qais Yousef <qyousef@layalina.io> Fixes: 3087c61ed2c4 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN") Reported-by: John Stultz <jstultz@google.com> Debugged-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Suggested-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Suggested-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> 12 February 2023, 15:23:39 UTC

a7152be Bjorn Helgaas 03 February 2023, 19:57:29 UTC Revert "PCI/ASPM: Save L1 PM Substates Capability for suspend/resume" This reverts commit 4ff116d0d5fd8a025604b0802d93a2d5f4e465d1. Tasev Nikola and Mark Enriquez reported that resume from suspend was broken in v6.1-rc1. Tasev bisected to a47126ec29f5 ("PCI/PTM: Cache PTM Capability offset"), but we can't figure out how that could be related. Mark saw the same symptoms and bisected to 4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"), which does have a connection: it restores L1 Substates configuration while ASPM L1 may be enabled: pci_restore_state pci_restore_aspm_l1ss_state aspm_program_l1ss pci_write_config_dword(PCI_L1SS_CTL1, ctl1) # L1SS restore pci_restore_pcie_state pcie_capability_write_word(PCI_EXP_LNKCTL, cap[i++]) # L1 restore which is a problem because PCIe r6.0, sec 5.5.4, requires that: If setting either or both of the enable bits for ASPM L1 PM Substates, both ports must be configured as described in this section while ASPM L1 is disabled. Separately, Thomas Witt reported that 5e85eba6f50d ("PCI/ASPM: Refactor L1 PM Substates Control Register programming") broke suspend/resume, and it depends on 4ff116d0d5fd. Revert 4ff116d0d5fd ("PCI/ASPM: Save L1 PM Substates Capability for suspend/resume") to fix the resume issue and enable revert of 5e85eba6f50d to fix the issue Thomas reported. Note that reverting 4ff116d0d5fd means L1 Substates config may be lost on suspend/resume. As far as we know the system will use more power but will still *work* correctly.

The previous implementation didn't guarantee the correct sequence of operations, which means flush_icache_all() hasn't been called when the PG_dcache_clean was set.

5f58d78 Anand Jain 20 January 2023, 13:47:16 UTC btrfs: free device in btrfs_close_devices for a single device filesystem We have this check to make sure we don't accidentally add older devices that may have disappeared and re-appeared with an older generation from being added to an fs_devices (such as a replace source device). This makes sense, we don't want stale disks in our file system. However for single disks this doesn't really make sense. I've seen this in testing, but I was provided a reproducer from a project that builds btrfs images on loopback devices. The loopback device gets cached with the new generation, and then if it is re-used to generate a new file system we'll fail to mount it because the new fs is "older" than what we have in cache. Fix this by freeing the cache when closing the device for a single device filesystem. This will ensure that the mount command passed device path is scanned successfully during the next mount.

519b7e1 Filipe Manana 23 January 2023, 16:54:46 UTC btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock (VFS lock), it only locks a file range in the inode's io tree. This however can lead to a deadlock if we have a concurrent fsync on the file and fiemap code triggers a fault when accessing the user space buffer with fiemap_fill_next_extent(). The deadlock happens on the inode's i_mmap_lock semaphore, which is taken both by fsync and btrfs_page_mkwrite().

Then when it enters extent_fiemap() and it locks a file range that includes the range of the page dirtied in step 2; 4) Task A calls btrfs_inode_lock() and locks the inode (VFS lock) and the inode's i_mmap_lock semaphore in write mode. Then it tries to flush delalloc by calling start_ordered_ops(), which will block, at find_lock_delalloc_range(), when trying to lock the range of the page dirtied at step 2, since this range was locked by the fiemap task (at step 3); 5) Task B generates a page fault when accessing the user space fiemap buffer with a call to fiemap_fill_next_extent(). The fault handler needs to call btrfs_page_mkwrite() for some other page of our inode, and there we deadlock when trying to lock the inode's i_mmap_lock semaphore in read mode, since the fsync task locked it in write mode (step 4) and the fsync task can not progress because it's waiting to lock a file range that is currently locked by us (the fiemap task, step 3). Fix this by taking the inode's lock (VFS lock) in shared mode when entering fiemap. This effectively serializes fiemap with fsync (except the most expensive part of fsync, the log sync), preventing this deadlock.

We've tried extensively to reproduce and debug the issue on a wide variety of platform configurations (DRAM bandwidth, etc.) and a variety of monitors, but so far have not been able to. We disabled S/G display on a number of platforms to address this but that leads to failure to pin framebuffers errors and blank displays when there is memory pressure or no displays at all on systems with limited carveout (e.g., Chromebooks). We have a parameter to disable this as a debugging option as a way for users to disable this, depending on their use case, and for us to help debug this further.

This manifests itself in a mode entry failure on certain docks and dongles with captive cables. For instance, the Startech.com Type-C to DP dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail the Pin Assignment compatibility check, despite it supporting Pin Assignment C as a UFP.

The type1_family smbios string is not an entirely reliable means of identifying systems with this issue as OEMs can, and do, use their own strings for these fields. However, until we have a better solution, capture the bulk of these systems by adding strcmp matching for "eMAG" and "Altra Max".

VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at &filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6. Simply put, when we populate the wrong key field, &filter->key.ipv6 fields "proto.mask" and "proto.value" remain all zeroes (or "don't care"). So is2_entry_set() will enter the "else" of this "if" condition: if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP)) and proceed to ignore the "proto" field. The resulting rule will match on all IPv6 traffic, trapping it to the CPU. This is the reason why the local_termination.sh selftest sees it, because control traps are stronger than the PGID_MCIPV6 used for flooding (from the forwarding data path). But the problem is in fact much deeper. We trap all IPv6 traffic to the CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software forwarding will not take place and IPv6 traffic will never reach its destination. The fix is simple - correct the typos. I was intentionally inaccurate in the commit message about the breakage occurring when any PTP timestamping is enabled. In fact it only happens when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT. I wanted people skimming through git logs to not think that the bug doesn't affect them because they only use ptp4l in L2 mode.

Happens that we faced a driver probe failure in the Steam Deck recently, and the function drm_sched_fini() was called even without its counter-part had been previously called, causing the following oops: amdgpu: probe of 0000:04:00.0 failed with error -110 BUG: kernel NULL pointer dereference, address: 0000000000000090 PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 609 Comm: systemd-udevd Not tainted 6.2.0-rc3-gpiccoli #338 Hardware name: Valve Jupiter/Jupiter, BIOS F7A0113 11/04/2022 RIP: 0010:drm_sched_fini+0x84/0xa0 [gpu_sched] [...] Call Trace: <TASK> amdgpu_fence_driver_sw_fini+0xc8/0xd0 [amdgpu] amdgpu_device_fini_sw+0x2b/0x3b0 [amdgpu] amdgpu_driver_release_kms+0x16/0x30 [amdgpu] devm_drm_dev_init_release+0x49/0x70 [...] To prevent that, check if the drm_sched was properly initialized for a given ring before calling its fini counter-part. Notice ideally we'd use sched.ready for that; such field is set as the latest thing on drm_sched_init().

1249db4 Paolo Abeni 07 February 2023, 13:04:16 UTC mptcp: be careful on subflow status propagation on errors Currently the subflow error report callback unconditionally propagates the fallback subflow status to the owning msk. If the msk is already orphaned, the above prevents the code from correctly tracking the msk moving to the TCP_CLOSE state and doing the appropriate cleanup. All the above causes increasing memory usage over time and sporadic self-tests failures. There is a great deal of infrastructure trying to propagate correctly the fallback subflow status to the owning mptcp socket, e.g. via mptcp_subflow_eof() and subflow_sched_work_if_closed(): in the error propagation path we need only to cope with unorphaned sockets.

ad21710 Paolo Abeni 07 February 2023, 13:04:15 UTC mptcp: fix locking for in-kernel listener creation For consistency, in mptcp_pm_nl_create_listen_socket(), we need to call the __mptcp_nmpc_socket() under the msk socket lock. Note that as a side effect, mptcp_subflow_create_socket() needs a 'nested' lockdep annotation, as it will acquire the subflow (kernel) socket lock under the in-kernel listener msk socket lock. The current lack of locking is almost harmless, because the relevant socket is not exposed to the user space, but in future we will add more complexity to the mentioned helper, let's play safe.

While the above is allowed by the protocol specification it consumes resources for almost no reason and additionally causes sporadic self-tests failures.

1a3245f Vladimir Oltean 07 February 2023, 10:30:27 UTC net: ethernet: mtk_eth_soc: fix DSA TX tag hwaccel for switch port 0 Arınç reports that on his MT7621AT Unielec U7621-06 board and MT7623NI Bananapi BPI-R2, packets received by the CPU over mt7530 switch port 0 (of which this driver acts as the DSA master) are not processed correctly by software. More precisely, they arrive without a DSA tag (in packet or in the hwaccel area - skb_metadata_dst()), so DSA cannot demux them towards the switch's interface for port 0. Traffic from other ports receives a skb_metadata_dst() with the correct port and is demuxed properly. Looking at mtk_poll_rx(), it becomes apparent that this driver uses the skb vlan hwaccel area: union { u32 vlan_all; struct { __be16 vlan_proto; __u16 vlan_tci; }; }; as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag. If this is a DSA master it's a DSA hwaccel tag, and finally clears up the skb VLAN hwaccel header. I'm guessing that the problem is the (mis)use of API. skb_vlan_tag_present() looks like this: #define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all) So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present() returns precisely false. I don't know for sure what is the format of the DSA hwaccel tag, but I surely know that lowermost 3 bits of vlan_proto are 0 when receiving from port 0: unsigned int port = vlan_proto & GENMASK(2, 0); If the RX descriptor has no other bits set to non-zero values in RX_DMA_VTAG, then the call to __vlan_hwaccel_put_tag() will not, in fact, make the subsequent skb_vlan_tag_present() return true, because it's implemented like this: static inline void __vlan_hwaccel_put_tag(struct sk_buff *skb, __be16 vlan_proto, u16 vlan_tci) { skb->vlan_proto = vlan_proto; skb->vlan_tci = vlan_tci; } What we need to do to fix this problem (assuming this is the problem) is to stop using skb->vlan_all as temporary storage for driver affairs, and just create some local variables that serve the same purpose, but hopefully better. Instead of calling skb_vlan_tag_present(), let's look at a boolean has_hwaccel_tag which we set to true when the RX DMA descriptors have something. Disambiguate based on netdev_uses_dsa() whether this is a VLAN or DSA hwaccel tag, and only call __vlan_hwaccel_put_tag() if we're certain it's a VLAN tag. Arınç confirms that the treatment works, so this validates the assumption.
