2023-04-11fbmem: Reject FB_ACTIVATE_KD_TEXT from userspaceDaniel Vetter
This is an oversight from dc5bdb68b5b3 ("drm/fb-helper: Fix vt restore") - I failed to realize that nasty userspace could set this. It's not pretty to mix up kernel-internal and userspace uapi flags like this, but since the entire fb_var_screeninfo structure is uapi we'd need to either add a new parameter to the ->fb_set_par callback and fb_set_par() function, which has a _lot_ of users. Or some other fairly ugly side-channel int fb_info. Neither is a pretty prospect. Instead just correct the issue at hand by filtering out this kernel-internal flag in the ioctl handling code.

2023-04-05accel/ivpu: Add dma fence to command buffers onlyKarol Wachowski
Currently job->done_fence is added to every BO handle within a job. If job handle (command buffer) is shared between multiple submits, KMD will add the fence in each of them. Then bo_wait_ioctl() executed on command buffer will exit only when all jobs containing that handle are done. This creates deadlock scenario for user mode driver in case when job handle is added as dependency of another job, because bo_wait_ioctl() of first job will wait until second job finishes, and second job can not finish before first one. Having fences added only to job buffer handle allows user space to execute bo_wait_ioctl() on the job even if it's handle is submitted with other job.

2023-03-29drm: test: Fix 32-bit issue in drm_buddy_testDavid Gow
The drm_buddy_test KUnit tests verify that returned blocks have sizes which are powers of two using is_power_of_2(). However, is_power_of_2() operations on a 'long', but the block size is a u64. So on systems where long is 32-bit, this can sometimes fail even on correctly sized blocks. This only reproduces randomly, as the parameters passed to the buddy allocator in this test are random. The seed 0xb2e06022 reproduced it fine here. For now, just hardcode an is_power_of_2() implementation using x & (x - 1).

2023-03-29drm: buddy_allocator: Fix buddy allocator init on 32-bit systemsDavid Gow
The drm buddy allocator tests were broken on 32-bit systems, as rounddown_pow_of_two() takes a long, and the buddy allocator handles 64-bit sizes even on 32-bit systems. This can be reproduced with the drm_buddy_allocator KUnit tests on i386: ./tools/testing/kunit/kunit.py run --arch i386 \ --kunitconfig ./drivers/gpu/drm/tests drm_buddy (It results in kernel BUG_ON() when too many blocks are created, due to the block size being too small.) This was independently uncovered (and fixed) by Luís Mendes, whose patch added a new u64 variant of rounddown_pow_of_two(). This version instead recalculates the size based on the order.

2023-03-29drm/nouveau/kms: Fix backlight registrationHans de Goede
The nouveau code used to call drm_fb_helper_initial_config() from nouveau_fbcon_init() before calling drm_dev_register(). This would probe all connectors so that drm_connector->status could be used during backlight registration which runs from nouveau_connector_late_register(). After commit 4a16dd9d18a0 ("drm/nouveau/kms: switch to drm fbdev helpers") the fbdev emulation code, which now is a drm-client, can only run after drm_dev_register(). So during backlight registration the connectors are not probed yet and the drm_connector->status == connected check in nv50_backlight_init() would now always fail. Replace the drm_connector->status == connected check with a drm_helper_probe_detect() == connected check to fix nv_backlight no longer getting registered because of this.

2023-03-12tpm: disable hwrng for fTPM on some AMD designsMario Limonciello
AMD has issued an advisory indicating that having fTPM enabled in BIOS can cause "stuttering" in the OS. This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439d58db ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.

2023-03-12tpm/eventlog: Don't abort tpm_read_log on faulty ACPI addressMorten Linderud
tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI table is found. If the firmware vendor includes an invalid log address we are unable to map from the ACPI memory and tpm_read_log() returns -EIO which would abort discovery of the eventlog. Change the return value from -EIO to -ENODEV when acpi_os_map_iomem() fails to map the event log. The following hardware was used to test this issue: Framework Laptop (Pre-production) BIOS: INSYDE Corp, Revision: 3.2 TPM Device: NTC, Firmware Revision: 7.2 Dump of the faulty ACPI TPM2 table: [000h 0000 4] Signature : "TPM2" [Trusted Platform Module hardware interface Table] [004h 0004 4] Table Length : 0000004C [008h 0008 1] Revision : 04 [009h 0009 1] Checksum : 2B [00Ah 0010 6] Oem ID : "INSYDE" [010h 0016 8] Oem Table ID : "TGL-ULT" [018h 0024 4] Oem Revision : 00000002 [01Ch 0028 4] Asl Compiler ID : "ACPI" [020h 0032 4] Asl Compiler Revision : 00040000 [024h 0036 2] Platform Class : 0000 [026h 0038 2] Reserved : 0000 [028h 0040 8] Control Address : 0000000000000000 [030h 0048 4] Start Method : 06 [Memory Mapped I/O] [034h 0052 12] Method Parameters : 00 00 00 00 00 00 00 00 00 00 00 00 [040h 0064 4] Minimum Log Length : 00010000 [044h 0068 8] Log Address : 000000004053D000 Fixes: 0cf577a03f21 ("tpm: Fix handling of missing event log") Tested-by: Erkki Eilonen <erkki@bearmetal.eu> Signed-off-by: Morten Linderud <morten@linderud.pw> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

2023-03-12cpumask: relax sanity checking constraintsLinus Torvalds
The cpumask_check() was unnecessarily tight, and causes problems for the users of cpumask_next(). We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.

I would've held that back until the merge window, if not for the mess it causes in tree topology - I've several branches merging from that one, and it's only going to get worse if e.g. ext2 stuff gets picked by Jan" * tag 'pull-highmem' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: new helper: put_and_unmap_page()

Pull misc fixes from Al Viro: "pick_file() speculation fix + fix for alpha mis(merge,cherry-pick) The fs/file.c one is a genuine missing speculation barrier in pick_file() (reachable e.g. via close(2)). The alpha one is strictly speaking not a bug fix, but only because confusion between preempt_enable() and preempt_disable() is harmless on architecture without CONFIG_PREEMPT. Looks like alpha.git picked the wrong version of patch - that braino used to be there in early versions, but it had been fixed quite a while ago..." * tag 'pull-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: prevent out-of-bounds array speculation when closing a file descriptor alpha: fix lazy-FPU mis(merged/applied/whatnot)
