The intent of this pull is to clean up the way callers fetch random integers. The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The prandom_bytes() function has been a deprecated inline wrapper around get_random_bytes() for several releases now, and compiles down to the exact same code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than truncate a 32-bit value to a 16-bit value or an 8-bit value, simply use the get_random_{u8,u16}() functions, which are faster than wasting the additional bytes from a 32-bit value.

Nobody else has reported this so this seems to be quite rare corner case. I don't know what specific commit started emitting this warning so I can't provide a Fixes tag. The function hasn't been touched for a year. I decided to workaround this by converting the pointer to a new array in stack, and then copying the data to the new array. It's only 16 bytes anyway and this is executed during association, so not in a hotpath.

Because, otherwise as before, if some new element is added later to the list in iwl_mvm_mac_wake_tx_queue, it can match with the old one and produce the same commented BUG. That is, in order to avoid this problem completely, we must also remove the related lists for the other cases when station queues are invalidated.

In that case, the hardware inserts a 2-byte length fields after the MAC addresses. For VLAN packets, this tag needs to be removed. However, for 802.3 LLC packets, the length bytes should be preserved, since there is no separate ethertype field in the data. This fixes an issue where the length field was omitted for LLC frames, causing them to be malformed after hardware decap.

This can cause an overread if the last cmd in the buffer is shorter than expected for the command type (with cmd->len showing the actual short size).

An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.

However, if guest GSO is not supported, it would be sufficient to allocate segments to cover just up the MTU size and no further. Allocating the maximum amount of segments results in a large waste of buffer space in the queue, which limits the number of packets that can be buffered and can result in reduced performance. Therefore, if guest GSO is not supported, use the MTU to calculate the optimal amount of segments required. Below is the iperf TCP test results over a Mellanox NIC, using vDPA for 1 VQ, queue size 1024, before and after the change, with the iperf server running over the virtio-net interface. MTU(Bytes)/Bandwidth (Gbit/s) Before After 1500 22.5 22.4 9000 12.8 25.9 And result of queue size 256. MTU(Bytes)/Bandwidth (Gbit/s) Before After 9000 2.15 11.9 With this patch no degradation is observed with multiple below tests and feature bit combinations. Results are summarized below for q depth of 1024. Interface MTU is 1500 if MTU feature is disabled. MTU is set to 9000 in other tests.

| * | | | hwrng: core - let sleep be interrupted when unregistering hwrngJason A. Donenfeld2022-08-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two deadlock scenarios that need addressing, which cause problems when the computer goes to sleep, the interface is set down, and hwrng_unregister() is called. When the deadlock is hit, sleep is delayed for tens of seconds, causing it to fail. These scenarios are: 1) The hwrng kthread can't be stopped while it's sleeping, because it uses msleep_interruptible() which does not react to kthread_stop. 2) A normal user thread can't be interrupted by hwrng_unregister() while it's sleeping, because hwrng_unregister() is called from elsewhere. We solve both issues by add a completion object called dying that fulfils waiters once we have started the process in hwrng_unregister. At the same time, we should cleanup a common and useless dmesg splat in the same area.

Lots of cleanups in here, no real new functionality this time around, with the diffstat being that we removed more lines than we added! Included in here are: - termios unification cleanups from Al Viro, it's nice to finally get this work done - tty serial transmit cleanups in various drivers in preparation for more cleanup and unification in future releases (that work was not ready for this release) - n_gsm fixes and updates - ktermios cleanups and code reductions - dt bindings json conversions and updates for new devices - some serial driver updates for new devices - lots of other tiny cleanups and janitorial stuff.
