2023-10-20efi/unaccepted: Fix soft lockups caused by parallel memory acceptanceKirill A. Shutemov1-4/+60
Michael reported soft lockups on a system that has unaccepted memory. This occurs when a user attempts to allocate and accept memory on multiple CPUs simultaneously. The root cause of the issue is that memory acceptance is serialized with a spinlock, allowing only one CPU to accept memory at a time. The other CPUs spin and wait for their turn, leading to starvation and soft lockup reports. To address this, the code has been modified to release the spinlock while accepting memory. This allows for parallel memory acceptance on multiple CPUs. A newly introduced "accepting_list" keeps track of which memory is currently being accepted. This is necessary to prevent parallel acceptance of the same memory block. If a collision occurs, the lock is released and the process is retried. Such collisions should rarely occur. The main path for memory acceptance is the page allocator, which accepts memory in MAX_ORDER chunks. As long as MAX_ORDER is equal to or larger than the unit_size, collisions will never occur because the caller fully owns the memory block being accepted. Aside from the page allocator, only memblock and deferered_free_range() accept memory, but this only happens during boot. The code has been tested with unit_size == 128MiB to trigger collisions and validate the retry codepath. Fixes: 2053bc57f367 ("efi: Add unaccepted memory support") Signed-off-by: Kirill A.

2023-10-20tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbolsFrancis Laniel2-0/+64
When a kprobe is attached to a function that's name is not unique (is static and shares the name with other functions in the kernel), the kprobe is attached to the first function it finds. This is a bug as the function that it is attaching to is not necessarily the one that the user wants to attach to. Instead of blindly picking a function to attach to what is ambiguous, error with EADDRNOTAVAIL to let the user know that this function is not unique, and that the user must use another unique function with an address offset to get to the function they want to attach to.

When removing the BPF event for perf a feature test that checks if the llvm devel files are availabe was removed but that is also used by bpftool. bpftool uses it to decide what kind of disassembly it will use: llvm or binutils based. Removing the tools/build/feature/test-llvm.cpp file made bpftool to always fallback to binutils disassembly, even with the llvm devel files installed, fix it by restoring just that small test-llvm.cpp test file.

2023-10-19iomap: fix short copy in iomap_write_iter()Jan Stancek1-3/+7
Starting with commit 5d8edfb900d5 ("iomap: Copy larger chunks from userspace"), iomap_write_iter() can get into endless loop. This can be reproduced with LTP writev07 which uses partially valid iovecs: struct iovec wr_iovec[] = { { buffer, 64 }, { bad_addr, 64 }, { buffer + 64, 64 }, { buffer + 64 * 2, 64 }, }; commit bc1bb416bbb9 ("generic_perform_write()/iomap_write_actor(): saner logics for short copy") previously introduced the logic, which made short copy retry in next iteration with amount of "bytes" it managed to copy: if (unlikely(status == 0)) { /* * A short copy made iomap_write_end() reject the * thing entirely. Might be memory poisoning * halfway through, might be a race with munmap, * might be severe memory pressure. */ if (copied) bytes = copied; However, since 5d8edfb900d5 "bytes" is no longer carried into next iteration, because it is now always initialized at the beginning of the loop. And for iov_iter_count < PAGE_SIZE, "bytes" ends up with same value as previous iteration, making the loop retry same copy over and over, which leads to writev07 testcase hanging. Make next iteration retry with amount of bytes we managed to copy.

2023-10-19Revert "ethtool: Fix mod state of verbose no_mask bitset"Kory Maincent1-26/+6
This reverts commit 108a36d07c01edbc5942d27c92494d1c6e4d45a0. It was reported that this fix breaks the possibility to remove existing WoL flags. For example: ~$ ethtool lan2 ... Supports Wake-on: pg Wake-on: d ... ~$ ethtool -s lan2 wol gp ~$ ethtool lan2 ... Wake-on: pg ... ~$ ethtool -s lan2 wol d ~$ ethtool lan2 ... Wake-on: pg ... This worked correctly before this commit because we were always updating a zero bitmap (since commit 6699170376ab ("ethtool: fix application of verbose no_mask bitset"), that is) so that the rest was left zero naturally. But now the 1->0 change (old_val is true, bit not present in netlink nest) no longer works.
