2021-10-28vfio/ccw: Convert to use vfio_register_emulated_iommu_dev()Jason Gunthorpe
This is a more complicated conversion because vfio_ccw is sharing the vfio_device between both the mdev_device, its vfio_device and the css_driver. The mdev is a singleton, and the reason for this sharing is so the extra css_driver function callbacks to be delivered to the vfio_device implementation. This keeps things as they are, with the css_driver allocating the singleton, not the mdev_driver. Embed the vfio_device in the vfio_ccw_private and instantiate it as a vfio_device when the mdev probes. The drvdata of both the css_device and the mdev_device point at the private, and container_of is used to get it back from the vfio_device.

2021-10-28ALSA: oxfw: fix functional regression for Mackie Onyx 1640i in v5.14 or laterTakashi Sakamoto
A user reports functional regression for Mackie Onyx 1640i that the device generates slow sound with ALSA oxfw driver which supports media clock recovery. Although the device is based on OXFW971 ASIC, it does not transfer isochronous packet with own event frequency as expected. The device seems to adjust event frequency according to events in received isochronous packets in the beginning of packet streaming. This is unknown quirk. This commit fixes the regression to turn the recovery off in driver side. As a result, nominal frequency is used in duplex packet streaming between device and driver. For stability of sampling rate in events of transferred isochronous packet, 4,000 isochronous packets are skipped in the beginning of packet streaming.

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Even though the current code uses dev->addr_len the we can switch to eth_hw_addr_set() instead of dev_addr_set(). The netdev is always allocated by alloc_etherdev_mq() and there are at least two places which assume Ethernet address: - the line below calling eth_hw_addr_random() - virtnet_set_mac_address() -> eth_commit_mac_addr_change() Acked-by: Michael S.

CN10k SoCs use atomic stores of up to 128 bytes to submit packets/instructions into co-processor cores. The enqueueing is performed using Large Memory Transaction Store (LMTST) operations. They allow for lockless enqueue operations - i.e., two different CPU cores can submit instructions to the same queue without needing to lock the queue or synchronize their accesses. This patch implements a new debugfs entry for dumping LMTST map table present on CN10K, as this might be very useful to debug any issue in case of shared LMTST region among multiple pci functions.

2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

2021-10-28net/tls: Fix flipped sign in tls_err_abort() callsDaniel Jordan
sk->sk_err appears to expect a positive value, a convention that ktls doesn't always follow and that leads to memory corruption in other code. For instance, [kworker] tls_encrypt_done(..., err=<negative error from crypto request>) tls_err_abort(.., err) sk->sk_err = err; [task] splice_from_pipe_feed ... tls_sw_do_sendpage if (sk->sk_err) { ret = -sk->sk_err; // ret is positive splice_from_pipe_feed (continued) ret = actor(...) // ret is still positive and interpreted as bytes // written, resulting in underflow of buf->len and // sd->len, leading to huge buf->offset and bogus // addresses computed in later calls to actor() Fix all tls_err_abort() callers to pass a negative error code consistently and centralize the error-prone sign flip there, throwing in a warning to catch future misuse and uninlining the function so it really does only warn once.

The variable err will be reassigned on subsequent branches, and this assignment does not perform related value operations. This will cause the double parentheses to be redundant, so the inner parentheses should be deleted. clang_analyzer complains as follows: drivers/net/ethernet/marvell/sky2.c:4988: warning: Although the value stored to 'err' is used in the enclosing expression, the value is never actually read from 'err'.

2021-10-28net: ipconfig: Release the rtnl_lock while waiting for carrierMaxime Chevallier
While waiting for a carrier to come on one of the netdevices, some devices will require to take the rtnl lock at some point to fully initialize all parts of the link. That's the case for SFP, where the rtnl is taken when a module gets detected. This prevents mounting an NFS rootfs over an SFP link. This means that while ipconfig waits for carriers to be detected, no SFP modules can be detected in the meantime, it's only detected after ipconfig times out. This commit releases the rtnl_lock while waiting for the carrier to come up, and re-takes it to check the for the init device and carrier status.

2021-10-28mwifiex: fix division by zero in fw download pathJohan Hovold
Add the missing endpoint sanity checks to probe() to avoid division by zero in mwifiex_write_data_sync() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Only add checks for the firmware-download boot stage, which require both command endpoints, for now. The driver looks like it will handle a missing endpoint during normal operation without oopsing, albeit not very gracefully as it will try to submit URBs to the default pipe and fail. Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).

2021-10-28selftests/x86/amx: Add context switch testChang S. Bae
XSAVE state is thread-local. The kernel switches between thread state at context switch time. Generally, running a selftest for a while will naturally expose it to some context switching and and will test the XSAVE code. Instead of just hoping that the tests get context-switched at random times, force context-switches on purpose. Spawn off a few userspace threads and force context-switches between them. Ensure that the kernel correctly context switches each thread's unique AMX state. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.

2021-10-28selftests/x86/amx: Add test cases for AMX state managementChang S. Bae
AMX TILEDATA is a very large XSAVE feature. It could have caused nasty XSAVE buffer space waste in two places: * Signal stacks * Kernel task_struct->fpu buffers To avoid this waste, neither of these buffers have AMX state by default. The non-default features are called "dynamic" features. There is an arch_prctl(ARCH_REQ_XCOMP_PERM) which allows a task to declare that it wants to use AMX or other "dynamic" XSAVE features. This arch_prctl() ensures that sufficient sigaltstack space is available before it will succeed. It also expands the task_struct buffer. Functions of this test: * Test arch_prctl(ARCH_REQ_XCOMP_PERM). Ensure that it checks for proper sigaltstack sizing and that the sizing is enforced for future sigaltstack calls. * Ensure that ARCH_REQ_XCOMP_PERM is inherited across fork() * Ensure that TILEDATA use before the prctl() is fatal * Ensure that TILEDATA is cleared across fork() Note: Generally, compiler support is needed to do something with AMX. Instead, directly load AMX state from userspace with a plain XSAVE. Do not depend on the compiler. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.
