[PATCH stable 5.10] sched/deadline: only set free_cpus for online runqueues

by Florian Fainelli

From: Doug Berger <opendmb(a)gmail.com> [ Upstream commit 382748c05e58a9f1935f5a653c352422375566ea ] Commit 16b269436b72 ("sched/deadline: Modify cpudl::free_cpus to reflect rd->online") introduced the cpudl_set/clear_freecpu functions to allow the cpu_dl::free_cpus mask to be manipulated by the deadline scheduler class rq_on/offline callbacks so the mask would also reflect this state. Commit 9659e1eeee28 ("sched/deadline: Remove cpu_active_mask from cpudl_find()") removed the check of the cpu_active_mask to save some processing on the premise that the cpudl::free_cpus mask already reflected the runqueue online state. Unfortunately, there are cases where it is possible for the cpudl_clear function to set the free_cpus bit for a CPU when the deadline runqueue is offline. When this occurs while a CPU is connected to the default root domain the flag may retain the bad state after the CPU has been unplugged. Later, a different CPU that is transitioning through the default root domain may push a deadline task to the powered down CPU when cpudl_find sees its free_cpus bit is set. If this happens the task will not have the opportunity to run. One example is outlined here: https://lore.kernel.org/lkml/20250110233010.2339521-1-opendmb@gmail.com Another occurs when the last deadline task is migrated from a CPU that has an offlined runqueue. The dequeue_task member of the deadline scheduler class will eventually call cpudl_clear and set the free_cpus bit for the CPU. This commit modifies the cpudl_clear function to be aware of the online state of the deadline runqueue so that the free_cpus mask can be updated appropriately. It is no longer necessary to manage the mask outside of the cpudl_set/clear functions so the cpudl_set/clear_freecpu functions are removed. In addition, since the free_cpus mask is now only updated under the cpudl lock the code was changed to use the non-atomic __cpumask functions.

[PATCH v12] Bluetooth: hci_qca: Fix SSR (SubSystem Restart) fail when BT_EN is pulled up by hw

by Shuai Zhang

On QCS9075 and QCA8275 platforms, the BT_EN pin is always pulled up by hw and cannot be controlled by the host. As a result, in case of a firmware crash, the host cannot trigger a cold reset. Instead, the BT controller performs a warm restart on its own, without reloading the firmware. This leads to the controller remaining in IBS_WAKE state, while the host expects it to be in sleep mode. The mismatch causes HCI reset commands to time out. Additionally, the driver does not clear internal flags QCA_SSR_TRIGGERED and QCA_IBS_DISABLED, which blocks the reset sequence. If the SSR duration exceeds 2 seconds, the host may enter TX sleep mode due to tx_idle_timeout, further preventing recovery. Also, memcoredump_flag is not cleared, so only the first SSR generates a coredump. Tell driver that BT controller has undergone a proper restart sequence: - Clear QCA_SSR_TRIGGERED and QCA_IBS_DISABLED flags after SSR. - Add a 50ms delay to allow the controller to complete its warm reset. - Reset tx_idle_timer to prevent the host from entering TX sleep mode. - Clear memcoredump_flag to allow multiple coredump captures. Apply these steps only when HCI_QUIRK_NON_PERSISTENT_SETUP is not set, which indicates that BT_EN is defined in DTS and cannot be toggled. Refer to the comment in include/net/bluetooth/hci.h for details on HCI_QUIRK_NON_PERSISTENT_SETUP. Changes in v12: - Rewrote commit to clarify the actual issue and affected platforms. - Used imperative language to describe the fix. - Explained the role of HCI_QUIRK_NON_PERSISTENT_SETUP.

The raw temperature data was never clamped to SPRD_THM_RAW_DATA_LOW or SPRD_THM_RAW_DATA_HIGH because the return value of clamp() was not used. Fix this by assigning the clamped value to 'rawdata'. Casting SPRD_THM_RAW_DATA_LOW and SPRD_THM_RAW_DATA_HIGH to u32 is also redundant and can be removed.

[PATCH v3] tpm2-sessions: address out-of-range indexing

by Jarkko Sakkinen

'name_size' does not have any range checks, and it just directly indexes with TPM_ALG_ID, which could lead into memory corruption at worst. Address the issue by only processing known values and returning -EINVAL for unrecognized values. Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so that errors are detected before causing any spurious TPM traffic. End also the authorization session on failure in both of the functions, as the session state would be then by definition corrupted. Cc: stable(a)vger.kernel.org # v6.10+ Fixes: 1085b8276bb4 ("tpm: Add the rest of the session HMAC API") Signed-off-by: Jarkko Sakkinen <jarkko(a)kernel.org> --- v3: - Add two missing 'tpm2_end_auth_session' calls to the fallback paths of 'tpm_buf_fill_hmac_session'. - Rewrote the commit message. - End authorization session on failure in 'tpm2_buf_append_name' and 'tpm_buf_fill_hmac_session'. v2: There was spurious extra field added to tpm2_hash by mistake. --- drivers/char/tpm/tpm2-cmd.c | 23 +++- drivers/char/tpm/tpm2-sessions.c | 131 +++++++++++++++------- include/linux/tpm.h | 6 +- security/keys/trusted-keys/trusted_tpm2.c | 29 ++++- 4 files changed, 136 insertions(+), 53 deletions(-) diff --git a/drivers/char/tpm/tpm2-cmd.c b/drivers/char/tpm/tpm2-cmd.c index 5b6ccf901623..4473b81122e8 100644 --- a/drivers/char/tpm/tpm2-cmd.c +++ b/drivers/char/tpm/tpm2-cmd.c @@ -187,7 +187,11 @@ int tpm2_pcr_extend(struct tpm_chip *chip, u32 pcr_idx, } if (!disable_pcr_integrity) { - tpm_buf_append_name(chip, &buf, pcr_idx, NULL);

[PATCH v2 2/4] tpm2-sessions: Fix tpm2_read_public range checks

'tpm2_read_public' has some rudimentary range checks but the function does not ensure that the response buffer has enough bytes for the full TPMT_HA payload.

[PATCH v2 1/4] tpm2-sessions: fix out of range indexing in name_size

by Jarkko Sakkinen

'name_size' does not have any range checks, and it just directly indexes with TPM_ALG_ID, which could lead into memory corruption at worst. Address the issue by only processing known values and returning -EINVAL for unrecognized values. Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so that errors are detected before causing any spurious TPM traffic. End also the authorization session on failure in both of the functions, as the session state would be then by definition corrupted. Cc: stable(a)vger.kernel.org # v6.10+ Fixes: 1085b8276bb4 ("tpm: Add the rest of the session HMAC API") Signed-off-by: Jarkko Sakkinen <jarkko(a)kernel.org> --- v2: - Wrote a better short summary. - Addressed remarks in https://lore.kernel.org/linux-integrity/aS8TIeviaippVAha@earth.li/ - Use -EIO consistently in tpm2_fill_hmac_session. These are not input value errors. They could only spun from malformed (kernel) state. - name_size did not have a proper default-case.
