2024-07-26smb3: add dynamic tracepoint for reflink errorsSteve French
There are cases where debugging clone_range ("smb2_duplicate_extents" function) and in the future copy_range ("smb2_copychunk_range") can be helpful. Add dynamic trace points for any errors in clone, and a followon patch will add them for copychunk.

2024-07-26arm64: allow installing compressed image by defaultLinus Torvalds
On arm64 we build compressed images, but "make install" by default will install the old non-compressed one. To actually get the compressed image install, you need to use "make zinstall", which is not the usual way to install a kernel. Which may not sound like much of an issue, but when you deal with multiple architectures (and years of your fingers knowing the regular "make install" incantation), this inconsistency is pretty annoying. But as Will Deacon says: "Sadly, bootloaders being as top quality as you might expect, I don't think we're in a position to rely on decompressor support across the board. Our Image.gz is literally just that -- we don't have a built-in decompressor (nor do I think we want to rush into that again after the fun we had on arm32) and the recent EFI zboot support solves that problem for platforms using EFI. Changing the default 'install' target terrifies me. There are bound to be folks with embedded boards who've scripted this and we could really ruin their day if we quietly give them a compressed kernel that their bootloader doesn't know how to handle :/" So make this conditional on a new "COMPRESSED_INSTALL" option.

2024-07-26io_uring/napi: use ktime in busy pollingPavel Begunkov
It's more natural to use ktime/ns instead of keeping around usec, especially since we're comparing it against user provided timers, so convert napi busy poll internal handling to ktime. It's also nicer since the type (ktime_t vs unsigned long) now tells the unit of measure. Keep everything as ktime, which we convert to/from micro seconds for IORING_[UN]REGISTER_NAPI. The net/ busy polling works seems to work with usec, however it's not real usec as shift by 10 is used to get it from nsecs, see busy_loop_current_time(), so it's easy to get truncated nsec back and we get back better precision. Note, we can further improve it later by removing the truncation and maybe convincing net/ to use ktime/ns instead.

2024-07-26RISC-V: Provide the frequency of time CSR via hwprobePalmer Dabbelt
The RISC-V architecture makes a real time counter CSR (via RDTIME instruction) available for applications in U-mode but there is no architected mechanism for an application to discover the frequency the counter is running at. Some applications (e.g., DPDK) use the time counter for basic performance analysis as well as fine grained time-keeping. Add support to the hwprobe system call to export the time CSR frequency to code running in U-mode.

2024-07-26riscv: Extend sv39 linear mapping max size to 128GStuart Menefy
This harmonizes all virtual addressing modes which can now all map (PGDIR_SIZE * PTRS_PER_PGD) / 4 of physical memory. The RISCV implementation of KASAN requires that the boundary between shallow mappings are aligned on an 8G boundary. In this case we need VMALLOC_START to be 8G aligned. So although we only need to move the start of the linear mapping down by 4GiB to allow 128GiB to be mapped, we actually move it down by 8GiB (creating a 4GiB hole between the linear mapping and KASAN shadow space) to maintain the alignment requirement.

2024-07-26riscv: Improve exception and system call latencyAnton Blanchard
Many CPUs implement return address branch prediction as a stack. The RISCV architecture refers to this as a return address stack (RAS). If this gets corrupted then the CPU will mispredict at least one but potentally many function returns. There are two issues with the current RISCV exception code: - We are using the alternate link stack (x5/t0) for the indirect branch which makes the hardware think this is a function return. This will corrupt the RAS. - We modify the return address of handle_exception to point to ret_from_exception. This will also corrupt the RAS. Testing the null system call latency before and after the patch: Visionfive2 (StarFive JH7110 / U74) baseline: 189.87 ns patched: 176.76 ns Lichee pi 4a (T-Head TH1520 / C910) baseline: 666.58 ns patched: 636.90 ns Just over 7% on the U74 and just over 4% on the C910.

The REQUEST_PROC_DAA command behaves differently from other commands. Sometimes the hardware can auto emit STOP, but in other conditions, it cannot. Improves the code logic to better handle these situations. Hardware can auto emit STOP only when the following conditions are met: - The previous I3C device correctly returns a PID and ACKs an I3C address. - A NACK is received when emitting 7E to try to get the next I3C device's PID. In all other cases, a manual STOP emission is needed. The code is changed to emit STOP when break the while loop and 'return 0' only when the hardware can auto emit STOP.

For the MIPI I3C HCI versions 1.0 and earlier the TABLE_SIZE field in the registers DAT_SECTION_OFFSET and DCT_SECTION_OFFSET is indeed defined in DWORDs and not number of entries like it is defined in later versions. Where above fix allowed driver initialization to continue the wrongly interpreted TABLE_SIZE field leads variables DAT_entries being twice and DCT_entries four times as big as they really are. That in turn leads clearing the DAT table over the boundary in the dat_v1.c: hci_dat_v1_init(). So interprete the TABLE_SIZE field in DWORDs for HCI versions < 1.1 and fix number of DAT/DCT entries accordingly.

According to I3C Spec 1.1.1, 11-Jun-2021, section: 5.1.2.2.3: If the Controller chooses to start an I3C Message with an I3C Dynamic Address, then special provisions shall be made because that same I3C Target may be initiating an IBI or a Controller Role Request. So, one of three things may happen: (skip 1, 2) 3. The Addresses match and the RnW bits also match, and so neither Controller nor Target will ACK since both are expecting the other side to provide ACK. As a result, each side might think it had "won" arbitration, but neither side would continue, as each would subsequently see that the other did not provide ACK. ... For either value of RnW: Due to the NACK, the Controller shall defer the Private Write or Private Read, and should typically transmit the Target ^^^^^^^^^^^^^^^^^^^ Address again after a Repeated START (i.e., the next one or any one prior ^^^^^^^^^^^^^ to a STOP in the Frame). Since the Address Header following a Repeated START is not arbitrated, the Controller will always win (see Section 5.1.2.2.4). Resend target address again if address is not 7E and controller get NACK.

2024-07-26erofs: fix race in z_erofs_get_gbuf()Gao Xiang
In z_erofs_get_gbuf(), the current task may be migrated to another CPU between `z_erofs_gbuf_id()` and `spin_lock(&gbuf->lock)`. Therefore, z_erofs_put_gbuf() will trigger the following issue which was found by stress test: <2>[772156.434168] kernel BUG at fs/erofs/zutil.c:58! .. <4>[772156.435007] <4>[772156.439237] CPU: 0 PID: 3078 Comm: stress Kdump: loaded Tainted: G E 6.10.0-rc7+ #2 <4>[772156.439239] Hardware name: Alibaba Cloud Alibaba Cloud ECS, BIOS 1.0.0 01/01/2017 <4>[772156.439241] pstate: 83400005 (Nzcv daif +PAN -UAO +TCO +DIT -SSBS BTYPE=--) <4>[772156.439243] pc : z_erofs_put_gbuf+0x64/0x70 [erofs] <4>[772156.439252] lr : z_erofs_lz4_decompress+0x600/0x6a0 [erofs] .. <6>[772156.445958] stress (3127): drop_caches: 1 <4>[772156.446120] Call trace: <4>[772156.446121] z_erofs_put_gbuf+0x64/0x70 [erofs] <4>[772156.446761] z_erofs_lz4_decompress+0x600/0x6a0 [erofs] <4>[772156.446897] z_erofs_decompress_queue+0x740/0xa10 [erofs] <4>[772156.447036] z_erofs_runqueue+0x428/0x8c0 [erofs] <4>[772156.447160] z_erofs_readahead+0x224/0x390 [erofs] ..
