* crypto: engine - fix crypto_queue backlog handlingOlivier Bacon2023-05-172-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 4140aafcff167b5b9e8dae6a1709a6de7cac6f74 ] CRYPTO_TFM_REQ_MAY_BACKLOG tells the crypto driver that it should internally backlog requests until the crypto hw's queue becomes full. At that point, crypto_engine backlogs the request and returns -EBUSY. Calling driver such as dm-crypt then waits until the complete() function is called with a status of -EINPROGRESS before sending a new request. The problem lies in the call to complete() with a value of -EINPROGRESS that is made when a backlog item is present on the queue. The call is done before the successful execution of the crypto request. In the case that do_one_request() returns < 0 and the retry support is available, the request is put back in the queue. This leads upper drivers to send a new request even if the queue is still full. The problem can be reproduced by doing a large dd into a crypto dm-crypt device. This is pretty easy to see when using Freescale CAAM crypto driver and SWIOTLB dma. Since the actual amount of requests that can be hold in the queue is unlimited we get IOs error and dma allocation. The fix is to call complete with a value of -EINPROGRESS only if the request is not enqueued back in crypto_queue. This is done by calling complete() later in the code. In order to delay the decision, crypto_queue is modified to correctly set the backlog pointer when a request is enqueued back.

* crypto: api - Add scaffolding to change completion function signatureHerbert Xu2023-05-172-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit c35e03eaece71101ff6cbf776b86403860ac8cc3 ] The crypto completion function currently takes a pointer to a struct crypto_async_request object. However, in reality the API does not allow the use of any part of the object apart from the data field. For example, ahash/shash will create a fake object on the stack to pass along a different data field. This leads to potential bugs where the user may try to dereference or otherwise use the crypto_async_request object. This patch adds some temporary scaffolding so that the completion function can take a void * instead. Once affected users have been converted this can be removed. The helper crypto_request_complete will remain even after the conversion is complete. It should be used instead of calling the completion function directly.

* perf cs-etm: Fix timeless decode mode detectionJames Clark2023-05-171-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 449067f3fc9f340da54e383738286881e6634d0b ] In this context, timeless refers to the trace data rather than the perf event data. But when detecting whether there are timestamps in the trace data or not, the presence of a timestamp flag on any perf event is used. Since commit f42c0ce573df ("perf record: Always get text_poke events with --kcore option") timestamps were added to a tracking event when --kcore is used which breaks this detection mechanism. Fix it by detecting if trace timestamps exist by looking at the ETM config flags. This would have always been a more accurate way of doing it anyway. This fixes the following error message when using --kcore with Coresight: $ perf record --kcore -e cs_etm// --per-thread $ perf report The perf.data/data data has no samples!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 120a56b01beed51ab5956a734adcfd2760307107 ] On mt753x_cpu_port_enable() there's code that enables flooding for the CPU port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports are enabled, port 6 becomes the only port to forward the frames to. But port 5 is the active port, so no frames received from the user ports will be forwarded to port 5 which breaks network connectivity. Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix this issue by setting the bit that corresponds to the CPU port without overwriting the other bits. Clear the bits beforehand only for the MT7531 switch. According to the documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and UNU_FFP bits are set to 1 for MT7531, 0 for MT7530. The commit 5e5502e012b8 ("net: dsa: mt7530: fix roaming from DSA user ports") silently changed the method to set the bits on the MT7530_MFC. Instead of clearing the relevant bits before mt7530_cpu_port_enable() which runs under a for loop, the commit started doing it on mt7530_cpu_port_enable(). Back then, this didn't really matter as only a single CPU port could be used since the CPU port number was hardcoded. The driver was later changed with commit 1f9a6abecf53 ("net: dsa: mt7530: get cpu-port via dp->cpu_dp instead of constant") to retrieve the CPU port via dp->cpu_dp. With that, this silent change became an issue for when using multiple CPU ports.

* net: dsa: mt7530: fix corrupt frames using trgmii on 40 MHz XTAL MT7621Arınç ÜNAL2023-05-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 37c218d8021e36e226add4bab93d071d30fe0704 ] The multi-chip module MT7530 switch with a 40 MHz oscillator on the MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using trgmii. This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL, hence using the ncpo1 value, 0x0780. My testing shows this value works on Unielec U7621-06, Bartel's testing shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices tested have got 40 MHz oscillators. Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code whilst 150 MHz PLL don't. Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz oscillator on the said MT7621 SoCs works fine because the ncpo1 value defined for it is for 125 MHz PLL. Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL ncpo1 values for both oscillator frequencies.

The old code is locking something it doesn't have a reference to, and as explained by Jason and David in this discussion: https://lore.kernel.org/linux-mm/Y9J4P%2FRNvY1Ztn0Q@nvidia.com/ it can lead to all kind of bad things, including the page getting unmapped (MADV_DONTNEED), freed, reallocated as a larger folio and the unlock_page() would target the wrong bit. There is also another race with the FOLL_WRITE, which could race between the follow_page() and the get_locked_pte(). The main point is to remove the last use of follow_page() without FOLL_GET or FOLL_PIN, removing the races can be considered a nice bonus.

Since 'struct ethtool_link_ksettings' is not initialized in this path, drivers receive an uninitialized number of lanes in 'struct ethtool_link_ksettings::lanes'. When this information is later queried from drivers, it results in the ethtool code making decisions based on uninitialized memory, leading to the following KMSAN splat [1]. In practice, this most likely only happens with the tun driver that simply returns whatever it got in the set operation. As far as I can tell, this uninitialized memory is not leaked to user space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in linkmodes_prepare_data(). Fix by initializing the structure in the IOCTL path. Did not find any more call sites that pass an uninitialized structure when calling 'ethtool_ops::set_link_ksettings()'.
