2024-02-05x86/efistub: Use 1:1 file:memory mapping for PE/COFF .compat sectionArd Biesheuvel
The .compat section is a dummy PE section that contains the address of the 32-bit entrypoint of the 64-bit kernel image if it is bootable from 32-bit firmware (i.e., CONFIG_EFI_MIXED=y) This section is only 8 bytes in size and is only referenced from the loader, and so it is placed at the end of the memory view of the image, to avoid the need for padding it to 4k, which is required for sections appearing in the middle of the image. Unfortunately, this violates the PE/COFF spec, and even if most EFI loaders will work correctly (including the Tianocore reference implementation), PE loaders do exist that reject such images, on the basis that both the file and memory views of the file contents should be described by the section headers in a monotonically increasing manner without leaving any gaps. So reorganize the sections to avoid this issue. This results in a slight padding overhead (< 4k) which can be avoided if desired by disabling CONFIG_EFI_MIXED (which is only needed in rare cases these days) Fixes: 3e3eabe26dc8 ("x86/boot: Increase section and file alignment to 4k/512") Reported-by: Mike Beaton <mjsbeaton@gmail.com> Link: https://lkml.kernel.org/r/CAHzAAWQ6srV6LVNdmfbJhOwhBw5ZzxxZZ07aHt9oKkfYAdvuQQ%40mail.gmail.com Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

2024-02-05bcachefs: install fd later to avoid race with closeMathias Krause
Calling fd_install() makes a file reachable for userland, including the possibility to close the file descriptor, which leads to calling its 'release' hook. If that happens before the code had a chance to bump the reference of the newly created task struct, the release callback will call put_task_struct() too early, leading to the premature destruction of the kernel thread. Avoid that race by calling fd_install() later, after all the setup is done.

2024-02-05powerpc/pseries/papr-sysparm: use u8 arrays for payloadsNathan Lynch
Some PAPR system parameter values are formatted by firmware as nul-terminated strings (e.g. LPAR name, shared processor attributes). But the values returned for other parameters, such as processor module info and TLB block invalidate characteristics, are binary data with parameter-specific layouts. So char[] isn't the appropriate type for the general case. Use u8/__u8.

2024-02-04iio: commom: st_sensors: ensure proper DMA alignmentNuno Sa
Aligning the buffer to the L1 cache is not sufficient in some platforms as they might have larger cacheline sizes for caches after L1 and thus, we can't guarantee DMA safety. That was the whole reason to introduce IIO_DMA_MINALIGN in [1]. Do the same for st_sensors common buffer. While at it, moved the odr_lock before buffer_data as we definitely don't want any other data to share a cacheline with the buffer.

2024-02-04hwmon: (coretemp) Fix bogus core_id to attr name mappingZhang Rui
Before commit 7108b80a542b ("hwmon/coretemp: Handle large core ID value"), there is a fixed mapping between 1. cpu_core_id 2. the index in pdata->core_data[] array 3. the sysfs attr name, aka "tempX_" The later two always equal cpu_core_id + 2. After the commit, pdata->core_data[] index is got from ida so that it can handle sparse core ids and support more cores within a package. However, the commit erroneously maps the sysfs attr name to pdata->core_data[] index instead of cpu_core_id + 2. As a result, the code is not aligned with the comments, and brings user visible changes in hwmon sysfs on systems with sparse core id. For example, before commit 7108b80a542b ("hwmon/coretemp: Handle large core ID value"), /sys/class/hwmon/hwmon2/temp2_label:Core 0 /sys/class/hwmon/hwmon2/temp3_label:Core 1 /sys/class/hwmon/hwmon2/temp4_label:Core 2 /sys/class/hwmon/hwmon2/temp5_label:Core 3 /sys/class/hwmon/hwmon2/temp6_label:Core 4 /sys/class/hwmon/hwmon3/temp10_label:Core 8 /sys/class/hwmon/hwmon3/temp11_label:Core 9 after commit, /sys/class/hwmon/hwmon2/temp2_label:Core 0 /sys/class/hwmon/hwmon2/temp3_label:Core 1 /sys/class/hwmon/hwmon2/temp4_label:Core 2 /sys/class/hwmon/hwmon2/temp5_label:Core 3 /sys/class/hwmon/hwmon2/temp6_label:Core 4 /sys/class/hwmon/hwmon2/temp7_label:Core 8 /sys/class/hwmon/hwmon2/temp8_label:Core 9 Restore the previous behavior and rework the code, comments and variable names to avoid future confusions.

If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER handler cannot perform VF register successfully as the register call is received before netvsc_probe is finished. This is because we register register_netdevice_notifier() very early( even before vmbus_driver_register()).

2024-02-03cxl/cper: Fix errant CPER prints for CXL eventsIra Weiny
Jonathan reports that CXL CPER events dump an extra generic error message. {1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1 {1}[Hardware Error]: event severity: recoverable {1}[Hardware Error]: Error 0, type: recoverable {1}[Hardware Error]: section type: unknown, fbcd0a77-c260-417f-85a9-088b1621eba6 {1}[Hardware Error]: section length: 0x90 {1}[Hardware Error]: 00000000: 00000090 00000007 00000000 0d938086 ................ {1}[Hardware Error]: 00000010: 00100000 00000000 00040000 00000000 ................ ... CXL events were rerouted though the CXL subsystem for additional processing. However, when that work was done it was missed that cper_estatus_print_section() continued with a generic error message which is confusing. Teach CPER print code to ignore printing details of some section types. Assign the CXL event GUIDs to this set to prevent confusing unknown prints.

2024-02-03tsnep: Fix mapping for zero copy XDP_TX actionGerhard Engleder
For XDP_TX action xdp_buff is converted to xdp_frame. The conversion is done by xdp_convert_buff_to_frame(). The memory type of the resulting xdp_frame depends on the memory type of the xdp_buff. For page pool based xdp_buff it produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy XSK pool based xdp_buff it produces xdp_frame with memory type MEM_TYPE_PAGE_ORDER0. tsnep_xdp_xmit_back() is not prepared for that and uses always the page pool buffer type TSNEP_TX_TYPE_XDP_TX. This leads to invalid mappings and the transmission of undefined data. Improve tsnep_xdp_xmit_back() to use the generic buffer type TSNEP_TX_TYPE_XDP_NDO for zero copy XDP_TX.

2024-02-02selftests: net: fix tcp listener handling in pmtu.shPaolo Abeni
The pmtu.sh test uses a few TCP listener in a problematic way: It hard-codes a constant timeout to wait for the listener starting-up in background. That introduces unneeded latency and on very slow and busy host it can fail. Additionally the test starts again the same listener in the same namespace on the same port, just after the previous connection completed. Fast host can attempt starting the new server before the old one really closed the socket. Address the issues using the wait_local_port_listen helper and explicitly waiting for the background listener process exit.

The ti->private could have had stale data, but instead of just initializing it to NULL, clear out the entire structure when it is allocated. - Fix a crash in timerlat The hrtimer was initialized at read and not open, but is canceled at close. If the file was opened and never read the close will pass a NULL pointer to hrtime_cancel(). - Rewrite of eventfs. Linus wrote a patch series to remove the dentry references in the eventfs_inode and to use ref counting and more of proper VFS interfaces to make it work. - Add warning to put_ei() if ei is not set to free. That means something is about to free it when it shouldn't. - Restructure the eventfs_inode to make it more compact, and remove the unused llist field. - Remove the fsnotify*() funtions for when the inodes were being created in the lookup code. It doesn't make sense to notify about creation just because something is being looked up. - The inode hard link count was not accurate. It was being updated when a file was looked up. The inodes of directories were updating their parent inode hard link count every time the inode was created. That means if memory reclaim cleaned a stale directory inode and the inode was lookup up again, it would increment the parent inode again as well. Al Viro said to just have all eventfs directories have a hard link count of 1.

Use a u64 instead of a u8 when taking a snapshot of pmu->fixed_ctr_ctrl when reprogramming fixed counters, as truncating the value results in KVM thinking fixed counter 2 is already disabled (the bug also affects fixed counters 3+, but KVM doesn't yet support those). As a result, if the guest disables fixed counter 2, KVM will get a false negative and fail to reprogram/disable emulation of the counter, which can leads to incorrect counts and spurious PMIs in the guest.
