Jakub Kicinski says: ==================== tcp_metrics: add netlink protocol spec in YAML Add a netlink protocol spec for the tcp_metrics generic netlink family. First patch adjusts the uAPI header guards to make it easier to build tools/ with non-system headers. v1: https://lore.kernel.org/all/20240626201133.2572487-1-kuba@kernel.org ==================== Signed-off-by: David S.

2024-07-01tcp_metrics: add netlink protocol spec in YAMLJakub Kicinski
Add a protocol spec for tcp_metrics, so that it's accessible via YNL. Useful at the very least for testing fixes. In this episode of "10,000 ways to complicate netlink" the metric nest has defines which are off by 1. iproute2 does: struct rtattr *m[TCP_METRIC_MAX + 1 + 1]; parse_rtattr_nested(m, TCP_METRIC_MAX + 1, a); for (i = 0; i < TCP_METRIC_MAX + 1; i++) { // ... attr = m[i + 1]; This is too weird to support in YNL, add a new set of defines with _correct_ values to the official kernel header.

2024-07-01tcp_metrics: add UAPI to the header guardJakub Kicinski
tcp_metrics' header lacks the customary _UAPI in the header guard. This makes YNL build rules work less seamlessly. We can easily fix that on YNL side, but this could also be problematic if we ever needed to create a kernel-only tcp_metrics.h.

2024-06-30ata: ahci: Clean up sysfs file on errorNiklas Cassel
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however, if probe() fails after this call, we currently never call sysfs_remove_file_from_group(). (The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one()) does not help, as .remove() is not called on .probe() error.) Thus, if probe() fails after the sysfs_add_file_to_group() call, the next time we insmod the module we will get: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:04.0/remapped_nvme' CPU: 11 PID: 954 Comm: modprobe Not tainted 6.10.0-rc5 #43 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x5d/0x80 sysfs_warn_dup.cold+0x17/0x23 sysfs_add_file_mode_ns+0x11a/0x130 sysfs_add_file_to_group+0x7e/0xc0 ahci_init_one+0x31f/0xd40 [ahci] Fixes: 894fba7f434a ("ata: ahci: Add sysfs attribute to show remapped NVMe device count") Cc: stable@vger.kernel.org Reviewed-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Hannes Reinecke <hare@suse.de> Link: https://lore.kernel.org/r/20240629124210.181537-10-cassel@kernel.org Signed-off-by: Niklas Cassel <cassel@kernel.org>

2024-06-30ata,scsi: libata-core: Do not leak memory for ata_port struct membersNiklas Cassel
libsas is currently not freeing all the struct ata_port struct members, e.g. ncq_sense_buf for a driver supporting Command Duration Limits (CDL). Add a function, ata_port_free(), that is used to free a ata_port, including its struct members. It makes sense to keep the code related to freeing a ata_port in its own function, which will also free all the struct members of struct ata_port.

2024-06-30x86-32: fix cmpxchg8b_emu build error with clangLinus Torvalds
The kernel test robot reported that clang no longer compiles the 32-bit x86 kernel in some configurations due to commit 95ece48165c1 ("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}() functions"). The build fails with arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available and the reason seems to be that not only does the cmpxchg8b instruction need four fixed registers (EDX:EAX and ECX:EBX), with the emulation fallback the inline asm also wants a fifth fixed register for the address (it uses %esi for that, but that's just a software convention with cmpxchg8b_emu). Avoiding using another pointer input to the asm (and just forcing it to use the "0(%esi)" addressing that we end up requiring for the sw fallback) seems to fix the issue.

2024-06-30erofs: ensure m_llen is reset to 0 if metadata is invalidGao Xiang
Sometimes, the on-disk metadata might be invalid due to user interrupts, storage failures, or other unknown causes. In that case, z_erofs_map_blocks_iter() may still return a valid m_llen while other fields remain invalid (e.g., m_plen can be 0). Due to the return value of z_erofs_scan_folio() in some path will be ignored on purpose, the following z_erofs_scan_folio() could then use the invalid value by accident. Let's reset m_llen to 0 to prevent this. Link: https://lore.kernel.org/r/20240629185743.2819229-1-hsiangkao@linux.alibaba.com Signed-off-by: Gao Xiang <hsiangkao@linux.alibaba.com>

2024-06-28selftests: drv-net: add ability to schedule cleanup with defer()Jakub Kicinski
This implements what I was describing in [1]. When writing a test author can schedule cleanup / undo actions right after the creation completes, eg: cmd("touch /tmp/file") defer(cmd, "rm /tmp/file") defer() takes the function name as first argument, and the rest are arguments for that function. defer()red functions are called in inverse order after test exits. It's also possible to capture them and execute earlier (in which case they get automatically de-queued). undo = defer(cmd, "rm /tmp/file") # ... some unsafe code ... undo.exec() As a nice safety all exceptions from defer()ed calls are captured, printed, and ignored (they do make the test fail, however). This addresses the common problem of exceptions in cleanup paths often being unhandled, leading to potential leaks. There is a global action queue, flushed by ksft_run(). We could support function level defers too, I guess, but there's no immediate need..
