tpm: disable hwrng for fTPM on some AMD designs

2023-03-12T21:28:10Z

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.

tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address

2023-03-12T21:28:10Z

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 Signed-off-by: Morten Linderud Reviewed-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen

The fixes are: - rtl8192e driver fixes for where the driver was attempting to execute various programs directly from the disk for unknown reasons - rtl8723bs driver fixes for issues found by Hans in testing The deleted driver is the removal of the r8188eu wireless driver as now in 6.3-rc1 we have a "real" wifi driver for one that includes support for many many more devices than this old driver did. So it's time to remove it as it is no longer needed. The maintainers of this driver all have acked its removal. Many thanks to them over the years for working to clean it up and keep it working while the real driver was being developed.

The flag reuses a bit from the CSIGNAL bits that are used in the legacy clone() system call to set the signal that gets sent to the parent after the child exits. The clone3() system call doesn't rely on CSIGNAL anymore as it uses a dedicated .exit_signal field in struct clone_args. So we blocked all CSIGNAL bits in clone3_args_valid(). When CLONE_NEWTIME was introduced and reused a CSIGNAL bit we forgot to adapt clone3_args_valid() causing CLONE_NEWTIME with clone3() to be rejected.
