commit f5ae2ea6 upstream. Intel Software Developer's Manual, volume 3, chapter 9.11.6 says: "Note that the microcode update must be aligned on a 16-byte boundary and the size of the microcode update must be 1-KByte granular" When early-load Intel microcode is loaded from initramfs, userspace tool 'iucode_tool' has already 16-byte aligned those microcode bits in that initramfs image. Image that was created something like this: iucode_tool --write-earlyfw=FOO.cpio microcode-files... However, when early-load Intel microcode is loaded from built-in firmware BLOB using CONFIG_EXTRA_FIRMWARE= kernel config option, that 16-byte alignment is not guaranteed. Fix this by forcing all built-in firmware BLOBs to 16-byte alignment. [ If we end up having other firmware with much bigger alignment requirements, we might need to introduce some method for the firmware to specify it, this is the minimal "just increase the alignment a bit to account for this one special case" patch - Linus ] Signed-off-by:

commit 3d615c2f upstream. A64-OLinuXino uses DCDC1 (VCC-IO) for MMC1 supply. In commit 916b68cf ("arm64: dts: a64-olinuxino: Enable RTL8723BS WiFi") ALDO2 is set, which is VCC-PL. Since DCDC1 is always present, the boards are working without a problem. This patch sets the correct regulator.

commit 5d1b7122 upstream. The altsetting sanity check in set_sync_ep_implicit_fb_quirk() was checking for there to be at least one altsetting but then went on to access the second one, which may not exist. This could lead to random slab data being used to initialise the sync endpoint in snd_usb_add_endpoint().

commit 60adcfde upstream. snd_seq_info_timer_read() reads the information of the timer assigned for each queue, but it's done in a racy way which may lead to UAF as spotted by syzkaller. This patch applies the missing q->timer_mutex lock while accessing the timer object as well as a slight code change to adapt the standard coding style.

commit 057efcf9 upstream. MIC BIAS Internal1 is broken at the moment because we always enable the internal rbias resistor to the TX2 line (connected to the headset microphone), rather than enabling the resistor connected to TX1. Move the RBIAS code to pm8916_wcd_analog_enable_micbias_int1/2() to fix this.

commit e0beec88 upstream. MIC BIAS External1 sets pm8916_wcd_analog_enable_micbias_ext1() as event handler, which ends up in pm8916_wcd_analog_enable_micbias_ext(). But pm8916_wcd_analog_enable_micbias_ext() only handles the POST_PMU event, which is not specified in the event flags for MIC BIAS External1. This means that the code in the event handler is never actually run. Set SND_SOC_DAPM_POST_PMU as the only event for the handler to fix this.

commit 28d76df1 upstream. Tom Hatskevich reported that we look up "iocp" then, in the called functions we do a second copy_from_user() and look it up again. The problem that could cause is: drivers/message/fusion/mptctl.c 674 /* All of these commands require an interrupt or 675 * are unknown/illegal. 676 */ 677 if ((ret = mptctl_syscall_down(iocp, nonblock)) != 0) ^^^^ We take this lock. 678 return ret; 679 680 if (cmd == MPTFWDOWNLOAD) 681 ret = mptctl_fw_download(arg); ^^^ Then the user memory changes and we look up "iocp" again but a different one so now we are holding the incorrect lock and have a race condition. 682 else if (cmd == MPTCOMMAND) 683 ret = mptctl_mpt_command(arg); The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power. But it's still worth fixing. This patch passes the "iocp" pointer to the functions to avoid the second lookup. That deletes 100 lines of code from the driver so it's a nice clean up as well.

commit fdb838ef upstream. USB-serial drivers must not be unbound from their ports before the corresponding USB driver is unbound from the parent interface so suppress the bind and unbind attributes. Unbinding a serial driver while it's port is open is a sure way to trigger a crash as any driver state is released on unbind while port hangup is handled on the parent USB interface level. Drivers for multiport devices where ports share a resource such as an interrupt endpoint also generally cannot handle individual ports going away.

commit accf227d upstream. RM500Q is a 5G module from Quectel, supporting both standalone and non-standalone modes. Unlike other recent Quectel modems, it is possible to identify the diagnostic interface (bInterfaceProtocol is unique). Thus, there is no need to check for the number of endpoints or reserve interfaces. The interface number is still dynamic though, so matching on interface number is not possible and two entries have to be added to the table.

commit 883f6165 upstream. Previous versions of `iio_compute_scan_bytes` only aligned each element to its own length (i.e. its own natural alignment). Because multiple consecutive sets of scan elements are buffered this does not work in case the computed scan bytes do not align with the natural alignment of the first scan element in the set. This commit fixes this by aligning the scan bytes to the natural alignment of the largest scan element in the set. Fixes: 959d2952 ("staging:iio: make iio_sw_buffer_preenable much more general.")

commit 85578bbd upstream. For some reason, attempting to route audio through QDSP6 on MSM8916 causes the RX interpolation path to get "stuck" after playing audio a few times. In this situation, the analog codec part is still working, but the RX path in the digital codec stops working, so you only hear the analog parts powering up. After a reboot everything works again. So far I was not able to reproduce the problem when using lpass-cpu. The downstream kernel driver avoids this by resetting the RX interpolation path after use. In mainline we do something similar for the TX decimator (LPASS_CDC_CLK_TX_RESET_B1_CTL), but the interpolator reset (LPASS_CDC_CLK_RX_RESET_CTL) got lost when the msm8916-wcd driver was split into analog and digital. Fix this problem by adding the reset to msm8916_wcd_digital_enable_interpolator().

commit 4881873f upstream. According to the public S805 datasheet the RESET2 register uses the following bits for the PIC_DC, PSC and NAND reset lines: - PIC_DC is at bit 3 (meaning: RESET_VD_RMEM + 3) - PSC is at bit 4 (meaning: RESET_VD_RMEM + 4) - NAND is at bit 5 (meaning: RESET_VD_RMEM + 4) Update the reset IDs of these three reset lines so they don't conflict with PIC_DC and map to the actual hardware reset lines.

commit 5e82548e upstream. On sdm845 devices, during boot we see the following warnings (unless we have added 'pd_ignore_unused' to the kernel command line): hlos1_vote_mmnoc_mmu_tbu_sf_gdsc status stuck at 'on' hlos1_vote_mmnoc_mmu_tbu_hf1_gdsc status stuck at 'on' hlos1_vote_mmnoc_mmu_tbu_hf0_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_tbu2_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_tbu1_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_pcie_tbu_gdsc status stuck at 'on' hlos1_vote_aggre_noc_mmu_audio_tbu_gdsc status stuck at 'on' As the name of these GDSCs suggests, they are "votable" and in downstream DT, they all have the property "qcom,no-status-check-on-disable", which means that we should not poll the status bit when we disable them. Luckily the VOTABLE flag already exists and it does exactly what we need, so let's make use of it to make the warnings disappear.

commit 46c9585e upstream. The PMU registers are at least 0x18 bytes wide. Meson8b already uses a size of 0x18. The structure of the PMU registers on Meson8 and Meson8b is similar but not identical. Meson8 and Meson8b have the following registers in common (starting at AOBUS + 0xe0): #define AO_RTI_PWR_A9_CNTL0 0xe0 (0x38 << 2) #define AO_RTI_PWR_A9_CNTL1 0xe4 (0x39 << 2) #define AO_RTI_GEN_PWR_SLEEP0 0xe8 (0x3a << 2) #define AO_RTI_GEN_PWR_ISO0 0x4c (0x3b << 2) Meson8b additionally has these three registers: #define AO_RTI_GEN_PWR_ACK0 0xf0 (0x3c << 2) #define AO_RTI_PWR_A9_MEM_PD0 0xf4 (0x3d << 2) #define AO_RTI_PWR_A9_MEM_PD1 0xf8 (0x3e << 2) Thus we can assume that the register size of the PMU IP blocks is identical on both SoCs (and Meson8 just contains some reserved registers in that area) because the CEC registers start right after the PMU (AO_RTI_*) registers at AOBUS + 0x100 (0x40 << 2). The upcoming power domain driver will need to read and write the AO_RTI_GEN_PWR_SLEEP0 and AO_RTI_GEN_PWR_ISO0 registers, so the updated size is needed for that driver to work.

[ Upstream commit 397eac17 ] If journal is dirty when mount, it will be replayed but jbd2 sb log tail cannot be updated to mark a new start because journal->j_flag has already been set with JBD2_ABORT first in journal_init_common. When a new transaction is committed, it will be recored in block 1 first(journal->j_tail is set to 1 in journal_reset). If emergency restart happens again before journal super block is updated unfortunately, the new recorded trans will not be replayed in the next mount. The following steps describe this procedure in detail. 1. mount and touch some files 2. these transactions are committed to journal area but not checkpointed 3. emergency restart 4. mount again and its journals are replayed 5. journal super block's first s_start is 1, but its s_seq is not updated 6. touch a new file and its trans is committed but not checkpointed 7. emergency restart again 8. mount and journal is dirty, but trans committed in 6 will not be replayed. This exception happens easily when this lun is used by only one node. If it is used by multi-nodes, other node will replay its journal and its journal super block will be updated after recovery like what this patch does. ocfs2_recover_node->ocfs2_replay_journal. The following jbd2 journal can be generated by touching a new file after journal is replayed, and seq 15 is the first valid commit, but first seq is 13 in journal super block. logdump: Block 0: Journal Superblock Seq: 0 Type: 4 (JBD2_SUPERBLOCK_V2) Blocksize: 4096 Total Blocks: 32768 First Block: 1 First Commit ID: 13 Start Log Blknum: 1 Error: 0 Feature Compat: 0 Feature Incompat: 2 block64 Feature RO compat: 0 Journal UUID: 4ED3822C54294467A4F8E87D2BA4BC36 FS Share Cnt: 1 Dynamic Superblk Blknum: 0 Per Txn Block Limit Journal: 0 Data: 0 Block 1: Journal Commit Block Seq: 14 Type: 2 (JBD2_COMMIT_BLOCK) Block 2: Journal Descriptor Seq: 15 Type: 1 (JBD2_DESCRIPTOR_BLOCK) No. Blocknum Flags 0. 587 none UUID: 00000000000000000000000000000000 1. 8257792 JBD2_FLAG_SAME_UUID 2. 619 JBD2_FLAG_SAME_UUID 3. 24772864 JBD2_FLAG_SAME_UUID 4. 8257802 JBD2_FLAG_SAME_UUID 5. 513 JBD2_FLAG_SAME_UUID JBD2_FLAG_LAST_TAG ...

[ Upstream commit 2f42e05b ] In some cases we seem to submit two transactions in a row, which causes us to lose track of the first. If we then cancel the request, we may still get an interrupt, which traverses a null ds_run value. So try to avoid starting a new transaction if the ds_run value is set. While this patch avoids the null pointer crash, I've had some reports of the k3dma driver still getting confused, which suggests the ds_run/ds_done value handling still isn't quite right. However, I've not run into an issue recently with it so I think this patch is worth pushing upstream to avoid the crash. Signed-off-by:
