2023-01-25riscv: Move call to init_cpu_topology() to later initialization stageLey Foon Tan
If "capacity-dmips-mhz" is present in a CPU DT node, topology_parse_cpu_capacity() will fail to allocate memory. arm64, with which this code path is shared, does not call topology_parse_cpu_capacity() until later in boot where memory allocation is available. While "capacity-dmips-mhz" is not yet a valid property on RISC-V, invalid properties should be ignored rather than cause issues. Move init_cpu_topology(), which calls topology_parse_cpu_capacity(), to a later initialization stage, to match arm64. As a side effect of this change, RISC-V is "protected" from changes to core topology code that would work on arm64 where memory allocation is safe but on RISC-V isn't.

2023-01-25net: mctp: mark socks as dead on unhash, prevent re-addJeremy Kerr
Once a socket has been unhashed, we want to prevent it from being re-used in a sk_key entry as part of a routing operation. This change marks the sk as SOCK_DEAD on unhash, which prevents addition into the net's key list. We need to do this during the key add path, rather than key lookup, as we release the net keys_lock between those operations.

Currently, we have a race where we look up a sock through a "general" (ie, not directly associated with the (src,dest,tag) tuple) key, then drop the key reference while still holding the key's sock.

2023-01-25platform/x86: thinkpad_acpi: Fix profile modes on Intel platformsMark Pearson
My last commit to fix profile mode displays on AMD platforms caused an issue on Intel platforms - sorry! In it I was reading the current functional mode (MMC, PSC, AMT) from the BIOS but didn't account for the fact that on some of our Intel platforms I use a different API which returns just the profile and not the functional mode. This commit fixes it so that on Intel platforms it knows the functional mode is always MMC. I also fixed a potential problem that a platform may try to set the mode for both MMC and PSC - which was incorrect. Tested on X1 Carbon 9 (Intel) and Z13 (AMD).

When listen() and accept() are called on an x25 socket that connect() succeeds, accept() succeeds immediately. This is because x25_connect() queues the skb to sk->sk_receive_queue, and x25_accept() dequeues it. This creates a child socket with the sk of the parent x25 socket, which can cause confusion.

2023-01-24ice: move devlink port creation/deletionPaul M Stillwell Jr
Commit a286ba738714 ("ice: reorder PF/representor devlink port register/unregister flows") moved the code to create and destroy the devlink PF port. This was fine, but created a corner case issue in the case of ice_register_netdev() failing. In that case, the driver would end up calling ice_devlink_destroy_pf_port() twice. Additionally, it makes no sense to tie creation of the devlink PF port to the creation of the netdev so separate out the code to create/destroy the devlink PF port from the netdev code. This makes it a cleaner interface.

2023-01-24sctp: fail if no bound addresses can be used for a given scopeMarcelo Ricardo Leitner
Currently, if you bind the socket to something like: servaddr.sin6_family = AF_INET6; servaddr.sin6_port = htons(0); servaddr.sin6_scope_id = 0; inet_pton(AF_INET6, "::1", &servaddr.sin6_addr); And then request a connect to: connaddr.sin6_family = AF_INET6; connaddr.sin6_port = htons(20000); connaddr.sin6_scope_id = if_nametoindex("lo"); inet_pton(AF_INET6, "fe88::1", &connaddr.sin6_addr); What the stack does is: - bind the socket - create a new asoc - to handle the connect - copy the addresses that can be used for the given scope - try to connect But the copy returns 0 addresses, and the effect is that it ends up trying to connect as if the socket wasn't bound, which is not the desired behavior. This unexpected behavior also allows KASLR leaks through SCTP diag interface. The fix here then is, if when trying to copy the addresses that can be used for the scope used in connect() it returns 0 addresses, bail out. This is what TCP does with a similar reproducer.

2023-01-24module: Don't wait for GOING modulesPetr Pavlu
During a system boot, it can happen that the kernel receives a burst of requests to insert the same module but loading it eventually fails during its init call. For instance, udev can make a request to insert a frequency module for each individual CPU when another frequency module is already loaded which causes the init function of the new module to return an error. Since commit 6e6de3dee51a ("kernel/module.c: Only return -EEXIST for modules that have finished loading"), the kernel waits for modules in MODULE_STATE_GOING state to finish unloading before making another attempt to load the same module. This creates unnecessary work in the described scenario and delays the boot. In the worst case, it can prevent udev from loading drivers for other devices and might cause timeouts of services waiting on them and subsequently a failed boot. This patch attempts a different solution for the problem 6e6de3dee51a was trying to solve. Rather than waiting for the unloading to complete, it returns a different error code (-EBUSY) for modules in the GOING state. This should avoid the error situation that was described in 6e6de3dee51a (user space attempting to load a dependent module because the -EEXIST error code would suggest to user space that the first module had been loaded successfully), while avoiding the delay situation too. This has been tested on linux-next since December 2022 and passes all kmod selftests except test 0009 with module compression enabled but it has been confirmed that this issue has existed and has gone unnoticed since prior to this commit and can also be reproduced without module compression with a simple usleep(5000000) on tools/modprobe.c [0]. These failures are caused by hitting the kernel mod_concurrent_max and can happen either due to a self inflicted kernel module auto-loead DoS somehow or on a system with large CPU count and each CPU count incorrectly triggering many module auto-loads. Both of those issues need to be fixed in-kernel.

2023-01-24ext4: make xattr char unsignedness in hash explicitLinus Torvalds
Commit f3bbac32475b ("ext4: deal with legacy signed xattr name hash values") added a hashing function for the legacy case of having the xattr hash calculated using a signed 'char' type. It left the unsigned case alone, since it's all implicitly handled by the '-funsigned-char' compiler option. However, there's been some noise about back-porting it all into stable kernels that lack the '-funsigned-char', so let's just make that at least possible by making the whole 'this uses unsigned char' very explicit in the code itself. Whether such a back-port is really warranted or not, I'll leave to others, but at least together with this change it is technically sensible. Also, add a 'pr_warn_once()' for reporting the "hey, signedness for this hash calculation has changed" issue. Hopefully it never triggers except for that xfstests generic/454 test-case, but even if it does it's just good information to have. If for no other reason than "we can remove the legacy signed hash code entirely if nobody ever sees the message any more".

2023-01-24thermal: intel: int340x: Protect trip temperature from concurrent updatesSrinivas Pandruvada
Trip temperatures are read using ACPI methods and stored in the memory during zone initializtion and when the firmware sends a notification for change. This trip temperature is returned when the thermal core calls via callback get_trip_temp(). But it is possible that while updating the memory copy of the trips when the firmware sends a notification for change, thermal core is reading the trip temperature via the callback get_trip_temp(). This may return invalid trip temperature. To address this add a mutex to protect the invalid temperature reads in the callback get_trip_temp() and int340x_thermal_read_trips().

2023-01-24ftrace/scripts: Update the instructions for ftrace-bisect.shSteven Rostedt (Google)
The instructions for the ftrace-bisect.sh script, which is used to find what function is being traced that is causing a kernel crash, and possibly a triple fault reboot, uses the old method. In 5.1, a new feature was added that let the user write in the index into available_filter_functions that maps to the function a user wants to set in set_ftrace_filter (or set_ftrace_notrace). This takes O(1) to set, as suppose to writing a function name, which takes O(n) (where n is the number of functions in available_filter_functions). The ftrace-bisect.sh requires setting half of the functions in available_filter_functions, which is O(n^2) using the name method to enable and can take several minutes to complete. The number method is O(n) which takes less than a second to complete. Using the number method for any kernel 5.1 and after is the proper way to do the bisect. Update the usage to reflect the new change, as well as using the /sys/kernel/tracing path instead of the obsolete debugfs path.

2023-01-24tracing: Make sure trace_printk() can output as soon as it can be usedSteven Rostedt (Google)
Currently trace_printk() can be used as soon as early_trace_init() is called from start_kernel(). But if a crash happens, and "ftrace_dump_on_oops" is set on the kernel command line, all you get will be: [ 0.456075] <idle>-0 0dN.2. 347519us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 353141us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 358684us : Unknown type 6 This is because the trace_printk() event (type 6) hasn't been registered yet. That gets done via an early_initcall(), which may be early, but not early enough. Instead of registering the trace_printk() event (and other ftrace events, which are not trace events) via an early_initcall(), have them registered at the same time that trace_printk() can be used. This way, if there is a crash before early_initcall(), then the trace_printk()s will actually be useful.

2023-01-24ftrace: Export ftrace_free_filter() to modulesMark Rutland
Setting filters on an ftrace ops results in some memory being allocated for the filter hashes, which must be freed before the ops can be freed. This can be done by removing every individual element of the hash by calling ftrace_set_filter_ip() or ftrace_set_filter_ips() with `remove` set, but this is somewhat error prone as it's easy to forget to remove an element. Make it easier to clean this up by exporting ftrace_free_filter(), which can be used to clean up all of the filter hashes after an ftrace_ops has been unregistered. Using this, fix the ftrace-direct* samples to free hashes prior to being unloaded. All other code either removes individual filters explicitly or is built-in and already calls ftrace_free_filter().

2023-01-24fuse: fixes after adapting to new posix acl apiChristian Brauner
This cycle we ported all filesystems to the new posix acl api. While looking at further simplifications in this area to remove the last remnants of the generic dummy posix acl handlers we realized that we regressed fuse daemons that don't set FUSE_POSIX_ACL but still make use of posix acls. With the change to a dedicated posix acl api interacting with posix acls doesn't go through the old xattr codepaths anymore and instead only relies the get acl and set acl inode operations. Before this change fuse daemons that don't set FUSE_POSIX_ACL were able to get and set posix acl albeit with two caveats. First, that posix acls aren't cached. And second, that they aren't used for permission checking in the vfs. We regressed that use-case as we currently refuse to retrieve any posix acls if they aren't enabled via FUSE_POSIX_ACL. So older fuse daemons would see a change in behavior. We can restore the old behavior in multiple ways. We could change the new posix acl api and look for a dedicated xattr handler and if we find one prefer that over the dedicated posix acl api. That would break the consistency of the new posix acl api so we would very much prefer not to do that. We could introduce a new ACL_*_CACHE sentinel that would instruct the vfs permission checking codepath to not call into the filesystem and ignore acls. But a more straightforward fix for v6.2 is to do the same thing that Overlayfs does and give fuse a separate get acl method for permission checking. Overlayfs uses this to express different needs for vfs permission lookup and acl based retrieval via the regular system call path as well. Let fuse do the same for now. This way fuse can continue to refuse to retrieve posix acls for daemons that don't set FUSE_POSXI_ACL for permission checking while allowing a fuse server to retrieve it via the usual system calls. In the future, we could extend the get acl inode operation to not just pass a simple boolean to indicate rcu lookup but instead make it a flag argument. Then in addition to passing the information that this is an rcu lookup to the filesystem we could also introduce a flag that tells the filesystem that this is a request from the vfs to use these acls for permission checking. Then fuse could refuse the get acl request for permission checking when the daemon doesn't have FUSE_POSIX_ACL set in the same get acl method. This would also help Overlayfs and allow us to remove the second method for it as well. But since that change is more invasive as we need to update the get acl inode operation for multiple filesystems we should not do this as a fix for v6.2. Instead we will do this for the v6.3 merge window. Fwiw, since posix acls are now always correctly translated in the new posix acl api we could also allow them to be used for daemons without FUSE_POSIX_ACL that are not mounted on the host. But this is behavioral change and again if dones should be done for v6.3. For now, let's just restore the original behavior. A nice side-effect of this change is that for fuse daemons with and without FUSE_POSIX_ACL the same code is used for posix acls in a backwards compatible way. This also means we can remove the legacy xattr handlers completely. We've also added comments to explain the expected behavior for daemons without FUSE_POSIX_ACL into the code.

2023-01-24ACPI: video: Fix apple gmux detectionHans de Goede
Some apple laptop models have an ACPI device with a HID of APP000B and that device has an IO resource (so it does not describe the new unsupported MMIO based gmux type), but there actually is no gmux in the laptop at all. The gmux_probe() function of the actual apple-gmux driver has code to detect this, this code has been factored out into a new apple_gmux_detect() helper in apple-gmux.h.

2023-01-24platform/x86: apple-gmux: Add apple_gmux_detect() helperHans de Goede
Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h which can be used for gmux detection instead of apple_gmux_present(). The latter is not really reliable since an ACPI device with a HID of APP000B is present on some devices without a gmux at all, as well as on devices with a newer (unsupported) MMIO based gmux model. This causes apple_gmux_present() to return false-positives on a number of different Apple laptop models. This new helper uses the same probing as the actual apple-gmux driver, so that it does not return false positives. To avoid code duplication the gmux_probe() function of the actual driver is also moved over to using the new apple_gmux_detect() helper.

2023-01-24platform/x86/amd: pmc: Disable IRQ1 wakeup for RN/CZNMario Limonciello
By default when the system is configured for low power idle in the FADT the keyboard is set up as a wake source. This matches the behavior that Windows uses for Modern Standby as well. It has been reported that a variety of AMD based designs there are spurious wakeups are happening where two IRQ sources are active. For example: ``` PM: Triggering wakeup from IRQ 9 PM: Triggering wakeup from IRQ 1 ``` In these designs IRQ 9 is the ACPI SCI and IRQ 1 is the keyboard. One way to trigger this problem is to suspend the laptop and then unplug the AC adapter. The SOC will be in a hardware sleep state and plugging in the AC adapter returns control to the kernel's s2idle loop. Normally if just IRQ 9 was active the s2idle loop would advance any EC transactions and no other IRQ being active would cause the s2idle loop to put the SOC back into hardware sleep state. When this bug occurred IRQ 1 is also active even if no keyboard activity occurred. This causes the s2idle loop to break and the system to wake. This is a platform firmware bug triggering IRQ1 without keyboard activity. This occurs in Windows as well, but Windows will enter "SW DRIPS" and then with no activity enters back into "HW DRIPS" (hardware sleep state). This issue affects Renoir, Lucienne, Cezanne, and Barcelo platforms. It does not happen on newer systems such as Mendocino or Rembrandt. It's been fixed in newer platform firmware. To avoid triggering the bug on older systems check the SMU F/W version and adjust the policy at suspend time for s2idle wakeup from keyboard on these systems. A lot of thought and experimentation has been given around the timing of disabling IRQ1, and to make it work the "suspend" PM callback is restored.
