2024-02-19platform/x86/amd/pmf: Remove smart_pc_status enumShyam Sundar S K
Improve code readability by removing smart_pc_status enum, as the same can be done with a simple true/false check; Update the code checks accordingly. Also add a missing return on amd_pmf_init_smart_pc() success, to skip trying to setup the auto / slider modes which should not be used in this case.

2024-02-19platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI namesHans de Goede
On some devices the ACPI name of the touchscreen is e.g. either MSSL1680:00 or MSSL1680:01 depending on the BIOS version. This happens for example on the "Chuwi Hi8 Air" tablet where the initial commit's ts_data uses "MSSL1680:00" but the tablets from the github issue and linux-hardware.org probe linked below both use "MSSL1680:01". Replace the strcmp() match on ts_data->acpi_name with a strstarts() check to allow using a partial match on just the ACPI HID of "MSSL1680" and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly to fix the touchscreen not working on models where it is "MSSL1680:01". Note this drops the length check for I2C_NAME_SIZE. This never was necessary since the ACPI names used are never more then 11 chars and I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long before reaching I2C_NAME_SIZE.

Older (mdp5) platforms do not use per-SoC compatible strings. Instead they use a single compat entry 'qcom,mdss'. To facilitate migrating these platforms to the DPU driver provide a way to generate the MDSS / UBWC data at runtime, when the DPU driver asks for it. It is not possible to generate this data structure at the probe time, since some platforms might not have MDP_CLK enabled, which makes reading HW_REV register useless and prone to possible crashes.

2024-02-19bpf: Fix racing between bpf_timer_cancel_and_free and bpf_timer_cancelMartin KaFai Lau
The following race is possible between bpf_timer_cancel_and_free and bpf_timer_cancel. It will lead a UAF on the timer->timer. bpf_timer_cancel(); spin_lock(); t = timer->time; spin_unlock(); bpf_timer_cancel_and_free(); spin_lock(); t = timer->timer; timer->timer = NULL; spin_unlock(); hrtimer_cancel(&t->timer); kfree(t); /* UAF on t */ hrtimer_cancel(&t->timer); In bpf_timer_cancel_and_free, this patch frees the timer->timer after a rcu grace period. This requires a rcu_head addition to the "struct bpf_hrtimer". Another kfree(t) happens in bpf_timer_init, this does not need a kfree_rcu because it is still under the spin_lock and timer->timer has not been visible by others yet. In bpf_timer_cancel, rcu_read_lock() is added because this helper can be used in a non rcu critical section context (e.g. from a sleepable bpf prog). Other timer->timer usages in helpers.c have been audited, bpf_timer_cancel() is the only place where timer->timer is used outside of the spin_lock. Another solution considered is to mark a t->flag in bpf_timer_cancel and clear it after hrtimer_cancel() is done. In bpf_timer_cancel_and_free, it busy waits for the flag to be cleared before kfree(t). This patch goes with a straight forward solution and frees timer->timer after a rcu grace period.

2024-02-19btrfs: fix deadlock with fiemap and extent lockingJosef Bacik
While working on the patchset to remove extent locking I got a lockdep splat with fiemap and pagefaulting with my new extent lock replacement lock. This deadlock exists with our normal code, we just don't have lockdep annotations with the extent locking so we've never noticed it. Since we're copying the fiemap extent to user space on every iteration we have the chance of pagefaulting. Because we hold the extent lock for the entire range we could mkwrite into a range in the file that we have mmap'ed. This would deadlock with the following stack trace [<0>] lock_extent+0x28d/0x2f0 [<0>] btrfs_page_mkwrite+0x273/0x8a0 [<0>] do_page_mkwrite+0x50/0xb0 [<0>] do_fault+0xc1/0x7b0 [<0>] __handle_mm_fault+0x2fa/0x460 [<0>] handle_mm_fault+0xa4/0x330 [<0>] do_user_addr_fault+0x1f4/0x800 [<0>] exc_page_fault+0x7c/0x1e0 [<0>] asm_exc_page_fault+0x26/0x30 [<0>] rep_movs_alternative+0x33/0x70 [<0>] _copy_to_user+0x49/0x70 [<0>] fiemap_fill_next_extent+0xc8/0x120 [<0>] emit_fiemap_extent+0x4d/0xa0 [<0>] extent_fiemap+0x7f8/0xad0 [<0>] btrfs_fiemap+0x49/0x80 [<0>] __x64_sys_ioctl+0x3e1/0xb50 [<0>] do_syscall_64+0x94/0x1a0 [<0>] entry_SYSCALL_64_after_hwframe+0x6e/0x76 I wrote an fstest to reproduce this deadlock without my replacement lock and verified that the deadlock exists with our existing locking. To fix this simply don't take the extent lock for the entire duration of the fiemap. This is safe in general because we keep track of where we are when we're searching the tree, so if an ordered extent updates in the middle of our fiemap call we'll still emit the correct extents because we know what offset we were on before. The only place we maintain the lock is searching delalloc. Since the delalloc stuff can change during writeback we want to lock the extent range so we have a consistent view of delalloc at the time we're checking to see if we need to set the delalloc flag. With this patch applied we no longer deadlock with my testcase.

2024-02-19btrfs: defrag: avoid unnecessary defrag caused by incorrect extent sizeQu Wenruo
[BUG] With the following file extent layout, defrag would do unnecessary IO and result more on-disk space usage. # mkfs.btrfs -f $dev # mount $dev $mnt # xfs_io -f -c "pwrite 0 40m" $mnt/foobar # sync # xfs_io -f -c "pwrite 40m 16k" $mnt/foobar # sync Above command would lead to the following file extent layout: item 6 key (257 EXTENT_DATA 0) itemoff 15816 itemsize 53 generation 7 type 1 (regular) extent data disk byte 298844160 nr 41943040 extent data offset 0 nr 41943040 ram 41943040 extent compression 0 (none) item 7 key (257 EXTENT_DATA 41943040) itemoff 15763 itemsize 53 generation 8 type 1 (regular) extent data disk byte 13631488 nr 16384 extent data offset 0 nr 16384 ram 16384 extent compression 0 (none) Which is mostly fine. We can allow the final 16K to be merged with the previous 40M, but it's upon the end users' preference. But if we defrag the file using the default parameters, it would result worse file layout: # btrfs filesystem defrag $mnt/foobar # sync item 6 key (257 EXTENT_DATA 0) itemoff 15816 itemsize 53 generation 7 type 1 (regular) extent data disk byte 298844160 nr 41943040 extent data offset 0 nr 8650752 ram 41943040 extent compression 0 (none) item 7 key (257 EXTENT_DATA 8650752) itemoff 15763 itemsize 53 generation 9 type 1 (regular) extent data disk byte 340787200 nr 33292288 extent data offset 0 nr 33292288 ram 33292288 extent compression 0 (none) item 8 key (257 EXTENT_DATA 41943040) itemoff 15710 itemsize 53 generation 8 type 1 (regular) extent data disk byte 13631488 nr 16384 extent data offset 0 nr 16384 ram 16384 extent compression 0 (none) Note the original 40M extent is still there, but a new 32M extent is created for no benefit at all. [CAUSE] There is an existing check to make sure we won't defrag a large enough extent (the threshold is by default 32M). But the check is using the length to the end of the extent: range_len = em->len - (cur - em->start); /* Skip too large extent */ if (range_len >= extent_thresh) goto next; This means, for the first 8MiB of the extent, the range_len is always smaller than the default threshold, and would not be defragged. But after the first 8MiB, the remaining part would fit the requirement, and be defragged. Such different behavior inside the same extent caused the above problem, and we should avoid different defrag decision inside the same extent. [FIX] Instead of using @range_len, just use @em->len, so that we have a consistent decision among the same file extent. Now with this fix, we won't touch the extent, thus not making it any worse.

In bond priority testing, we set the primary interface to eth1 and add eth0,1,2 to bond in serial. This is OK in normal times.

Also switch all error prints inside those functions to use dev_err_probe() for consistency.

Now the flag is set unconditionally when RS485 is enabled. This results in an incorrect setting if the rx-during-tx GPIO is not asserted. Fix this by setting the flag only if the rx-during-tx mode is not controlled by a GPIO and thus restore the correct behaviour.

Stop calling drm_bridge_remove() for bridges allocated/managed by other drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}. drm_bridge_remove() unregisters the bridge so it cannot be used anymore. Doing so for bridges we don't own can lead to the video pipeline not being able to come up after -EPROBE_DEFER of the VPU because we're unregistering a bridge that's managed by another driver. The other driver doesn't know that we have unregistered it's bridge and on subsequent .probe() we're not able to find those bridges anymore (since nobody re-creates them).

2024-02-19usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBsKrishna Kurapati
It is observed sometimes when tethering is used over NCM with Windows 11 as host, at some instances, the gadget_giveback has one byte appended at the end of a proper NTB. When the NTB is parsed, unwrap call looks for any leftover bytes in SKB provided by u_ether and if there are any pending bytes, it treats them as a separate NTB and parses it. But in case the second NTB (as per unwrap call) is faulty/corrupt, all the datagrams that were parsed properly in the first NTB and saved in rx_list are dropped. Adding a few custom traces showed the following: [002] d..1 7828.532866: dwc3_gadget_giveback: ep1out: req 000000003868811a length 1025/16384 zsI ==> 0 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10 [002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames In this case, the giveback is of 1025 bytes and block length is 1024. The rest 1 byte (which is 0x00) won't be parsed resulting in drop of all datagrams in rx_list. Same is case with packets of size 2048: [002] d..1 7828.557948: dwc3_gadget_giveback: ep1out: req 0000000011dfd96e length 2049/16384 zsI ==> 0 [002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800 Lecroy shows one byte coming in extra confirming that the byte is coming in from PC: Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590) - Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590) --- Packet 4063861 Data(1024 bytes) Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590) --- Packet 4063863 Data(1 byte) Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722) According to Windows driver, no ZLP is needed if wBlockLength is non-zero, because the non-zero wBlockLength has already told the function side the size of transfer to be expected. However, there are in-market NCM devices that rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize. To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize.
