2024-01-31Input: bcm5974 - check endpoint type before starting trafficJavier Carrasco
syzbot has found a type mismatch between a USB pipe and the transfer endpoint, which is triggered by the bcm5974 driver[1]. This driver expects the device to provide input interrupt endpoints and if that is not the case, the driver registration should terminate. Repros are available to reproduce this issue with a certain setup for the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in the USB core after calling usb_submit_urb() with the following message: "BOGUS urb xfer, pipe 1 != type 3" Some other device drivers (like the appletouch driver bcm5974 is mainly based on) provide some checking mechanism to make sure that an IN interrupt endpoint is available. In this particular case the endpoint addresses are provided by a config table, so the checking can be targeted to the provided endpoints. Add some basic checking to guarantee that the endpoints available match the expected type for both the trackpad and button endpoints. This issue was only found for the trackpad endpoint, but the checking has been added to the button endpoint as well for the same reasons. Given that there was never a check for the endpoint type, this bug has been there since the first implementation of the driver (f89bd95c5c94).

2024-01-31kconfig: initialize sym->curr.tri to 'no' for all symbol types againMasahiro Yamada
Geert Uytterhoeven reported that commit 4e244c10eab3 ("kconfig: remove unneeded symbol_empty variable") changed the default value of CONFIG_LOG_CPU_MAX_BUF_SHIFT from 12 to 0. As it turned out, this is an undefined behavior because sym_calc_value() stopped setting the sym->curr.tri field for 'int', 'hex', and 'string' symbols. This commit restores the original behavior, where 'int', 'hex', 'string' symbols are interpreted as false if used in boolean contexts. CONFIG_LOG_CPU_MAX_BUF_SHIFT will default to 12 again, irrespective of CONFIG_BASE_SMALL. Presumably, this is not the intended behavior, as already reported [1], but this is another issue that should be addressed by a separate patch.

2024-01-31dma-buf: heaps: Don't track CMA dma-buf pages under RssFileT.J. Mercier
DMA buffers allocated from the CMA dma-buf heap get counted under RssFile for processes that map them and trigger page faults. In addition to the incorrect accounting reported to userspace, reclaim behavior was influenced by the MM_FILEPAGES counter until linux 6.8, but this memory is not reclaimable. [1] Change the CMA dma-buf heap to set VM_PFNMAP on the VMA so MM does not poke at the memory managed by this dma-buf heap, and use vmf_insert_pfn to correct the RSS accounting. The system dma-buf heap does not suffer from this issue since remap_pfn_range is used during the mmap of the buffer, which also sets VM_PFNMAP on the VMA.

2024-01-31kbuild: rpm-pkg: simplify installkernel %postJose Ignacio Tornos Martinez
The new installkernel application that is now included in systemd-udev package allows installation although destination files are already present in the boot directory of the kernel package, but is failing with the implemented workaround for the old installkernel application from grubby package. For the new installkernel application, as Davide says: <<The %post currently does a shuffling dance before calling installkernel. This isn't actually necessary afaict, and the current implementation ends up triggering downstream issues such as https://github.com/systemd/systemd/issues/29568 This commit simplifies the logic to remove the shuffling. For reference, the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post section to create initramfs and grub hooks").>> But we need to keep the old behavior as well, because the old installkernel application from grubby package, does not allow this simplification and we need to be backward compatible to avoid issues with the different packages. Mimic Fedora shipping process and store vmlinuz, config amd System.map in the module directory instead of the boot directory. In this way, we will avoid the commented problem for all the cases, because the new destination files are not going to exist in the boot directory of the kernel package. Replace installkernel tool with kernel-install tool, because the latter is more complete. Besides, after installkernel tool execution, check to complete if the correct package files vmlinuz, System.map and config files are present in /boot directory, and if necessary, copy manually for install operation. In this way, take into account if files were not previously copied from /usr/lib/kernel/install.d/* scripts and if the suitable files for the requested package are present (it could be others if the rpm files were replace with a new pacakge with the same release and a different build).

2024-01-30bridge: mcast: fix disabled snooping after long uptimeLinus Lüssing
The original idea of the delay_time check was to not apply multicast snooping too early when an MLD querier appears. And to instead wait at least for MLD reports to arrive before switching from flooding to group based, MLD snooped forwarding, to avoid temporary packet loss. However in a batman-adv mesh network it was noticed that after 248 days of uptime 32bit MIPS based devices would start to signal that they had stopped applying multicast snooping due to missing queriers - even though they were the elected querier and still sending MLD queries themselves. While time_is_before_jiffies() generally is safe against jiffies wrap-arounds, like the code comments in jiffies.h explain, it won't be able to track a difference larger than ULONG_MAX/2. With a 32bit large jiffies and one jiffies tick every 10ms (CONFIG_HZ=100) on these MIPS devices running OpenWrt this would result in a difference larger than ULONG_MAX/2 after 248 (= 2^32/100/60/60/24/2) days and time_is_before_jiffies() would then start to return false instead of true. Leading to multicast snooping not being applied to multicast packets anymore. Fix this issue by using a proper timer_list object which won't have this ULONG_MAX/2 difference limitation.

2024-01-30misc: fastrpc: Mark all sessions as invalid in cb_removeEkansh Gupta
In remoteproc shutdown sequence, rpmsg_remove will get called which would depopulate all the child nodes that have been created during rpmsg_probe. This would result in cb_remove call for all the context banks for the remoteproc. In cb_remove function, session 0 is getting skipped which is not correct as session 0 will never become available again. Add changes to mark session 0 also as invalid.

2024-01-30Input: xpad - add Lenovo Legion Go controllersBrenton Simpson
The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck. It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad, volume buttons, a power button, and 2 LED ring lights. The Legion Go firmware presents these controls as a USB hub with various devices attached. In its default state, the gamepad is presented as an Xbox controller connected to this hub. (By holding a combination of buttons, it can be changed to use the older DirectInput API.) This patch teaches the existing Xbox controller module `xpad` to bind to the controller in the Legion Go, which enables support for the: - directional pad, - analog sticks (including clicks), - X, Y, A, B, - start and select (or menu and capture), - shoulder buttons, and - rumble. The trackpad, touchscreen, volume controls, and power button are already supported via existing kernel modules. Two of the face buttons, the gyroscopes, rear paddles, and LEDs are not. After this patch lands, the Legion Go will be mostly functional in Linux, out-of-the-box. The various components of the USB hub can be synthesized into a single logical controller (including the additional buttons) in userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which makes the Go fully functional.

2024-01-30soc: apple: mailbox: error pointers are negative integersLinus Torvalds
In an entirely unrelated discussion where I pointed out a stupid thinko of mine, Rasmus piped up and noted that that obvious mistake already existed elsewhere in the kernel tree. An "error pointer" is the negative error value encoded as a pointer, making the whole "return error or valid pointer" use-case simple and straightforward. We use it all over the kernel. But the key here is that errors are _negative_ error numbers, not the horrid UNIX user-level model of "-1 and the value of 'errno'". The Apple mailbox driver used the positive error values, and thus just returned invalid normal pointers instead of actual errors. Of course, the reason nobody ever noticed is that the errors presumably never actually happen, so this is fixing a conceptual bug rather than an actual one.

2024-01-30parisc: Fix random data corruption from exception handlerHelge Deller
The current exception handler implementation, which assists when accessing user space memory, may exhibit random data corruption if the compiler decides to use a different register than the specified register %r29 (defined in ASM_EXCEPTIONTABLE_REG) for the error code. If the compiler choose another register, the fault handler will nevertheless store -EFAULT into %r29 and thus trash whatever this register is used for. Looking at the assembly I found that this happens sometimes in emulate_ldd(). To solve the issue, the easiest solution would be if it somehow is possible to tell the fault handler which register is used to hold the error code. Using %0 or %1 in the inline assembly is not posssible as it will show up as e.g. %r29 (with the "%r" prefix), which the GNU assembler can not convert to an integer. This patch takes another, better and more flexible approach: We extend the __ex_table (which is out of the execution path) by one 32-word. In this word we tell the compiler to insert the assembler instruction "or %r0,%r0,%reg", where %reg references the register which the compiler choosed for the error return code. In case of an access failure, the fault handler finds the __ex_table entry and can examine the opcode. The used register is encoded in the lowest 5 bits, and the fault handler can then store -EFAULT into this register. Since we extend the __ex_table to 3 words we can't use the BUILDTIME_TABLE_SORT config option any longer. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # v6.0+
2024-01-30kselftest/seccomp: Report each expectation we assert as a KTAP testMark Brown
The seccomp benchmark test makes a number of checks on the performance it measures and logs them to the output but does so in a custom format which none of the automated test runners understand meaning that the chances that anyone is paying attention are slim. Let's additionally log each result in KTAP format so that automated systems parsing the test output will see each comparison as a test case. The original logs are left in place since they provide the actual numbers for analysis. As part of this rework the flow for the main program so that when we skip tests we still log all the tests we skip, this is because the standard KTAP headers and footers include counts of the number of expected and run tests.

2024-01-30selftests/livepatch: fix and refactor new dmesg message codeJoe Lawrence
The livepatching kselftests rely on comparing expected vs. observed dmesg output. After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev <agordeev@linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b2-a85c-c5cc2836eea2.ibm.com/ Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com> Acked-by: Alexander Gordeev <agordeev@linux.ibm.com> Tested-by: Marcos Paulo de Souza <mpdesouza@suse.com> Reviewed-by: Marcos Paulo de Souza <mpdesouza@suse.com> Acked-by: Miroslav Benes <mbenes@suse.cz> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
