2022-06-21afs: Fix dynamic root getattrDavid Howells
The recent patch to make afs_getattr consult the server didn't account for the pseudo-inodes employed by the dynamic root-type afs superblock not having a volume or a server to access, and thus an oops occurs if such a directory is stat'd. Fix this by checking to see if the vnode->volume pointer actually points anywhere before following it in afs_getattr(). This can be tested by stat'ing a directory in /afs. It may be sufficient just to do "ls /afs" and the oops looks something like: BUG: kernel NULL pointer dereference, address: 0000000000000020 ... RIP: 0010:afs_getattr+0x8b/0x14b ...

2022-06-19perf arm-spe: Don't set data source if it's not a memory operationLeo Yan
Except for memory load and store operations, ARM SPE records also can support other operation types, bug when set the data source field the current code assumes a record is a either load operation or store operation, this leads to wrongly synthesize memory samples. This patch strictly checks the record operation type, it only sets data source only for the operation types ARM_SPE_LD and ARM_SPE_ST, otherwise, returns zero for data source. Therefore, we can synthesize memory samples only when data source is a non-zero value, the function arm_spe__is_memory_event() is useless and removed.

2022-06-19perf test: Fix "perf stat CSV output linter" test on s390Thomas Richter
perf test -F 83 ("perf stat CSV output linter") fails on s390. Reason is the wrong number of fields for certain CPU core/die/socket related output. On x84_64 the output of command: # ./perf stat -x, -A -a --no-merge true CPU0,1.50,msec,cpu-clock,1502781,100.00,1.052,CPUs utilized CPU1,1.48,msec,cpu-clock,1476113,100.00,1.034,CPUs utilized ... results in 8 fields with 7 comma separators. On s390 the output of command: # ./perf stat -x, -A -a --no-merge -- true 0.95,msec,cpu-clock,949800,100.00,1.060,CPUs utilized ... results in 7 fields with 6 comma separators. Therefore this tests fails on s390. Similar issues exist for per-die and per-socket output which is not supported on s390. I have rewritten the python program to count commas in each output line into a bash function to achieve the same result. I hope this makes it a bit easier. Output before: # ./perf test -F 83 83: perf stat CSV output linter : Checking CSV output: no args [Success] Checking CSV output: system wide [Success] Checking CSV output: system wide Checking CSV output: \ system wide no aggregation 6.92,msec,cpu-clock,\ 6918131,100.00,6.972,CPUs utilized ...

2022-06-18ext4: fix up test_dummy_encryption handling for new mount APIEric Biggers
Since ext4 was converted to the new mount API, the test_dummy_encryption mount option isn't being handled entirely correctly, because the needed fscrypt_set_test_dummy_encryption() helper function combines parsing/checking/applying into one function. That doesn't work well with the new mount API, which split these into separate steps. This was sort of okay anyway, due to the parsing logic that was copied from fscrypt_set_test_dummy_encryption() into ext4_parse_param(), combined with an additional check in ext4_check_test_dummy_encryption(). However, these overlooked the case of changing the value of test_dummy_encryption on remount, which isn't allowed but ext4 wasn't detecting until ext4_apply_options() when it's too late to fail. Another bug is that if test_dummy_encryption was specified multiple times with an argument, memory was leaked. Fix this up properly by using the new helper functions that allow splitting up the parse/check/apply steps for test_dummy_encryption.

2022-06-17x86/tdx: Handle load_unaligned_zeropad() page-cross to a shared pageKirill A. Shutemov
load_unaligned_zeropad() can lead to unwanted loads across page boundaries. The unwanted loads are typically harmless. But, they might be made to totally unrelated or even unmapped memory. load_unaligned_zeropad() relies on exception fixup (#PF, #GP and now #VE) to recover from these unwanted loads. In TDX guests, the second page can be shared page and a VMM may configure it to trigger #VE. The kernel assumes that #VE on a shared page is an MMIO access and tries to decode instruction to handle it. In case of load_unaligned_zeropad() it may result in confusion as it is not MMIO access. Fix it by detecting split page MMIO accesses and failing them. load_unaligned_zeropad() will recover using exception fixups. The issue was discovered by analysis and reproduced artificially. It was not triggered during testing. [ dhansen: fix up changelogs and comments for grammar and clarity, plus incorporate Kirill's off-by-one fix] Signed-off-by: Kirill A.

2022-06-17x86/PCI: Revert "x86/PCI: Clip only host bridge windows for E820 regions"Hans de Goede
This reverts commit 4c5e242d3e93. Prior to 4c5e242d3e93 ("x86/PCI: Clip only host bridge windows for E820 regions"), E820 regions did not affect PCI host bridge windows. We only looked at E820 regions and avoided them when allocating new MMIO space. If firmware PCI bridge window and BAR assignments used E820 regions, we left them alone. After 4c5e242d3e93, we removed E820 regions from the PCI host bridge windows before looking at BARs, so firmware assignments in E820 regions looked like errors, and we moved things around to fit in the space left (if any) after removing the E820 regions. This unnecessary BAR reassignment broke several machines. Guilherme reported that Steam Deck fails to boot after 4c5e242d3e93. We clipped the window that contained most 32-bit BARs: BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff] which forced us to reassign all those BARs, for example, this NVMe BAR: pci 0000:00:01.2: PCI bridge to [bus 01] pci 0000:00:01.2: bridge window [mem 0x80600000-0x806fffff] pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit] pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff] pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit] All the reassignments were successful, so the devices should have been functional at the new addresses, but some were not. Andy reported a similar failure on an Intel MID platform. Benjamin reported a similar failure on a VMWare Fusion VM. Note: this is not a clean revert; this revert keeps the later change to make the clipping dependent on a new pci_use_e820 bool, moving the checking of this bool to arch_remove_reservations().

Pull io_uring fixes from Jens Axboe: "Bigger than usual at this time, both because we missed -rc2, but also because of some reverts that we chose to do. In detail: - Adjust mapped buffer API while we still can (Dylan) - Mapped buffer fixes (Dylan, Hao, Pavel, me) - Fix for uring_cmd wrong API usage for task_work (Dylan) - Fix for bug introduced in fixed file closing (Hao) - Fix race in buffer/file resource handling (Pavel) - Revert the NOP support for CQE32 and buffer selection that was brought up during the merge window (Pavel) - Remove IORING_CLOSE_FD_AND_FILE_SLOT introduced in this merge window. The API needs further refining, so just yank it for now and we'll revisit for a later kernel. - Series cleaning up the CQE32 support added in this merge window, making it more integrated rather than sitting on the side (Pavel)" * tag 'io_uring-5.19-2022-06-16' of git://git.kernel.dk/linux-block: (21 commits) io_uring: recycle provided buffer if we punt to io-wq io_uring: do not use prio task_work_add in uring_cmd io_uring: commit non-pollable provided mapped buffers upfront io_uring: make io_fill_cqe_aux honour CQE32 io_uring: remove __io_fill_cqe() helper io_uring: fix ->extra{1,2} misuse io_uring: fill extra big cqe fields from req io_uring: unite fill_cqe and the 32B version io_uring: get rid of __io_fill_cqe{32}_req() io_uring: remove IORING_CLOSE_FD_AND_FILE_SLOT Revert "io_uring: add buffer selection support to IORING_OP_NOP" Revert "io_uring: support CQE32 for nop operation" io_uring: limit size of provided buffer ring io_uring: fix types in provided buffer ring io_uring: fix index calculation io_uring: fix double unlock for pbuf select io_uring: kbuf: fix bug of not consuming ring buffer in partial io case io_uring: openclose: fix bug of closing wrong fixed file io_uring: fix not locked access to fixed buf table io_uring: fix races with buffer table unregister ...
