2022-09-28rust: add C helpersMiguel Ojeda1-0/+51
Introduces the source file that will contain forwarders to C macros and inlined functions. Initially this only contains a single helper, but will gain more as more functionality is added to the `kernel` crate in the future.

2022-09-28kallsyms: increase maximum kernel symbol length to 512Miguel Ojeda6-8/+8
Rust symbols can become quite long due to namespacing introduced by modules, types, traits, generics, etc. For instance, the following code: pub mod my_module { pub struct MyType; pub struct MyGenericType<T>(T); pub trait MyTrait { fn my_method() -> u32; } impl MyTrait for MyGenericType<MyType> { fn my_method() -> u32 { 42 } } } generates a symbol of length 96 when using the upcoming v0 mangling scheme: _RNvXNtCshGpAVYOtgW1_7example9my_moduleINtB2_13MyGenericTypeNtB2_6MyTypeENtB2_7MyTrait9my_method At the moment, Rust symbols may reach up to 300 in length. Setting 512 as the maximum seems like a reasonable choice to keep some headroom.

2022-09-28kallsyms: support "big" kernel symbolsMiguel Ojeda2-7/+48
Rust symbols can become quite long due to namespacing introduced by modules, types, traits, generics, etc. Increasing to 255 is not enough in some cases, therefore introduce longer lengths to the symbol table. In order to avoid increasing all lengths to 2 bytes (since most of them are small, including many Rust ones), use ULEB128 to keep smaller symbols in 1 byte, with the rest in 2 bytes.

2022-09-27vdpa/mlx5: Fix MQ to support non power of two num queuesEli Cohen1-7/+10
RQT objects require that a power of two value be configured for both rqt_max_size and rqt_actual size. For create_rqt, make sure to round up to the power of two the value of given by the user who created the vdpa device and given by ndev->rqt_size. The actual size is also rounded up to the power of two using the current number of VQs given by ndev->cur_num_vqs. Same goes with modify_rqt where we need to make sure act size is power of two based on the new number of QPs. Without this patch, attempt to create a device with non power of two QPs would result in error from firmware.

[Why] We rely on DMCUB to do this when disabling the link but it should actually come before we disable the DP VID stream. If we don't then the FIFO can end up with underflow that persists the next time it's enabled. [How] Add a DCN314 specific blank sequence that will disable the DIG FIFO first.

2022-09-27x86/alternative: Fix race in try_get_desc()Nadav Amit1-22/+23
I encountered some occasional crashes of poke_int3_handler() when kprobes are set, while accessing desc->vec. The text poke mechanism claims to have an RCU-like behavior, but it does not appear that there is any quiescent state to ensure that nobody holds reference to desc. As a result, the following race appears to be possible, which can lead to memory corruption. CPU0 CPU1 ---- ---- text_poke_bp_batch() -> smp_store_release(&bp_desc, &desc) [ notice that desc is on the stack ] poke_int3_handler() [ int3 might be kprobe's so sync events are do not help ] -> try_get_desc(descp=&bp_desc) desc = __READ_ONCE(bp_desc) if (!desc) [false, success] WRITE_ONCE(bp_desc, NULL); atomic_dec_and_test(&desc.refs) [ success, desc space on the stack is being reused and might have non-zero value. ] arch_atomic_inc_not_zero(&desc->refs) [ might succeed since desc points to stack memory that was freed and might be reused. ] Fix this issue with small backportable patch. Instead of trying to make RCU-like behavior for bp_desc, just eliminate the unnecessary level of indirection of bp_desc, and hold the whole descriptor as a global. Anyhow, there is only a single descriptor at any given moment.
