The selftest can reproduce an issue where we miss the uncharge operation when freeing msg, which will cause the following warning. We fixed the issue and added this reproducer to selftest to ensure it will not happen again. ------------[ cut here ]------------ WARNING: CPU: 1 PID: 40 at net/ipv4/af_inet.c inet_sock_destruct+0x173/0x1d5 Tainted: [W]=WARN Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014 Workqueue: events sk_psock_destroy RIP: 0010:inet_sock_destruct+0x173/0x1d5 RSP: 0018:ffff8880085cfc18 EFLAGS: 00010202 RAX: 1ffff11003dbfc00 RBX: ffff88801edfe3e8 RCX: ffffffff822f5af4 RDX: 0000000000000007 RSI: dffffc0000000000 RDI: ffff88801edfe16c RBP: ffff88801edfe184 R08: ffffed1003dbfc31 R09: 0000000000000000 R10: ffffffff822f5ab7 R11: ffff88801edfe187 R12: ffff88801edfdec0 R13: ffff888020376ac0 R14: ffff888020376ac0 R15: ffff888020376a60 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000556365155830 CR3: 000000001d6aa000 CR4: 0000000000350ef0 Call Trace: <TASK> __sk_destruct+0x46/0x222 sk_psock_destroy+0x22f/0x242 process_one_work+0x504/0x8a8 ? process_one_work+0x39d/0x8a8 ? __pfx_process_one_work+0x10/0x10 ? worker_thread+0x44/0x2ae ? __list_add_valid_or_report+0x83/0xea ? srso_return_thunk+0x5/0x5f ? __list_add+0x45/0x52 process_scheduled_works+0x73/0x82 worker_thread+0x1ce/0x2ae Acked-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Jiayuan Chen <jiayuan.chen@linux.dev> Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org> Link: https://lore.kernel.org/r/20250425060015.6968-3-jiayuan.chen@linux.dev |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
