2021-04-07vfio/mdev: Simplify driver registrationJason Gunthorpe
This is only done once, we don't need to generate code to initialize a structure stored in the ELF .data segment. Fill in the three required .driver members directly instead of copying data into them during mdev_register_driver(). Further the to_mdev_driver() function doesn't belong in a public header, just inline it into the two places that need it. Finally, we can now clearly see that 'drv' derived from dev->driver cannot be NULL, firstly because the driver core forbids it, and secondly because NULL won't pass through the container_of(). Remove the dead code.

2021-04-07vfio/mdev: Add missing typesafety around mdev_deviceJason Gunthorpe
The mdev API should accept and pass a 'struct mdev_device *' in all places, not pass a 'struct device *' and cast it internally with to_mdev_device(). Particularly in its struct mdev_driver functions, the whole point of a bus's struct device_driver wrapper is to provide type safety compared to the default struct device_driver. Further, the driver core standard is for bus drivers to expose their device structure in their public headers that can be used with container_of() inlines and '&foo->dev' to go between the class levels, and '&foo->dev' to be used with dev_err/etc driver core helper functions. Move 'struct mdev_device' to mdev.h Once done this allows moving some one instruction exported functions to static inlines, which in turns allows removing one of the two grotesque symbol_get()'s related to mdev in the core code.

Subsequent changes will cause the exit_latency_ns and target_residency_ns fields in struct cpuidle_state to be used in computations in which data type conversions to u64 may turn a negative number close to zero into a verly large positive number leading to incorrect results. In preparation for that, change the data type of the fields mentioned above to s64, but ensure that they will not be negative themselves. No intentional functional impact. Signed-off-by: Rafael J.

2021-04-07mtd: rawnand: Add support for secure regions in NAND memoryManivannan Sadhasivam
On a typical end product, a vendor may choose to secure some regions in the NAND memory which are supposed to stay intact between FW upgrades. The access to those regions will be blocked by a secure element like Trustzone. So the normal world software like Linux kernel should not touch these regions (including reading). The regions are declared using a NAND chip DT property, "secure-regions". So let's make use of this property in the raw NAND core and skip access to the secure regions present in a system.

2021-04-07iio:event: Add timeout event info typeJonathan Cameron
For adaptive threshold events, the current value is compared with a (typically) low pass filtered version of the same signal that slowly tracks large scale changes. However, sometimes a step change can result in a large lag before the low pass filtered version begins to track the signal again. Timeouts can be used to made an instantaneous 'correction'. Documentation of this attribute is added in a later patch.

2021-04-07bus: mhi: core: Remove pre_init flag used for power purposesBhaumik Bhatt
Some controllers can choose to skip preparation for power up. In that case, device context is initialized based on the pre_init flag not being set during mhi_prepare_for_power_up(). There is no reason MHI host driver should maintain and provide controllers with two separate paths for preparing MHI. Going forward, all controllers will be required to call the mhi_prepare_for_power_up() API followed by their choice of sync or async power up. This allows MHI host driver to get rid of the pre_init flag and sets up a common way for all controllers to use MHI. This also helps controllers fail early on during preparation phase in some failure cases.

2021-04-07bpf, sockmap: Fix sk->prot unhash op resetJohn Fastabend
In '4da6a196f93b1' we fixed a potential unhash loop caused when a TLS socket in a sockmap was removed from the sockmap. This happened because the unhash operation on the TLS ctx continued to point at the sockmap implementation of unhash even though the psock has already been removed. The sockmap unhash handler when a psock is removed does the following, void sock_map_unhash(struct sock *sk) { void (*saved_unhash)(struct sock *sk); struct sk_psock *psock; rcu_read_lock(); psock = sk_psock(sk); if (unlikely(!psock)) { rcu_read_unlock(); if (sk->sk_prot->unhash) sk->sk_prot->unhash(sk); return; } [...] } The unlikely() case is there to handle the case where psock is detached but the proto ops have not been updated yet. But, in the above case with TLS and removed psock we never fixed sk_prot->unhash() and unhash() points back to sock_map_unhash resulting in a loop. To fix this we added this bit of code, static inline void sk_psock_restore_proto(struct sock *sk, struct sk_psock *psock) { sk->sk_prot->unhash = psock->saved_unhash; This will set the sk_prot->unhash back to its saved value. This is the correct callback for a TLS socket that has been removed from the sock_map. Unfortunately, this also overwrites the unhash pointer for all psocks. We effectively break sockmap unhash handling for any future socks. Omitting the unhash operation will leave stale entries in the map if a socket transition through unhash, but does not do close() op. To fix set unhash correctly before calling into tls_update. This way the TLS enabled socket will point to the saved unhash() handler.

2021-04-06virtio_net: Do not pull payload in skb->headEric Dumazet
Xuan Zhuo reported that commit 3226b158e67c ("net: avoid 32 x truesize under-estimation for tiny skbs") brought a ~10% performance drop. The reason for the performance drop was that GRO was forced to chain sk_buff (using skb_shinfo(skb)->frag_list), which uses more memory but also cause packet consumers to go over a lot of overhead handling all the tiny skbs. It turns out that virtio_net page_to_skb() has a wrong strategy : It allocates skbs with GOOD_COPY_LEN (128) bytes in skb->head, then copies 128 bytes from the page, before feeding the packet to GRO stack. This was suboptimal before commit 3226b158e67c ("net: avoid 32 x truesize under-estimation for tiny skbs") because GRO was using 2 frags per MSS, meaning we were not packing MSS with 100% efficiency. Fix is to pull only the ethernet header in page_to_skb() Then, we change virtio_net_hdr_to_skb() to pull the missing headers, instead of assuming they were already pulled by callers. This fixes the performance regression, but could also allow virtio_net to accept packets with more than 128bytes of headers. Many thanks to Xuan Zhuo for his report, and his tests/help.
