Title
afs: Fix lock recursion
Summary
In the Linux kernel, the following vulnerability has been resolved: afs: Fix lock recursion afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, which might try taking the ->notify_lock again. This case isn't very common, however, so defer it to a workqueue. The oops looks something like: BUG: spinlock recursion on CPU#0, krxrpcio/7001/1646 lock: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0 CPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 Not tainted 6.12.0-rc2-build3+ #4351 Hardware name: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 Call Trace: <TASK> dump_stack_lvl+0x47/0x70 do_raw_spin_lock+0x3c/0x90 rxrpc_kernel_shutdown_call+0x83/0xb0 afs_put_call+0xd7/0x180 rxrpc_notify_socket+0xa0/0x190 rxrpc_input_split_jumbo+0x198/0x1d0 rxrpc_input_data+0x14b/0x1e0 ? rxrpc_input_call_packet+0xc2/0x1f0 rxrpc_input_call_event+0xad/0x6b0 rxrpc_input_packet_on_conn+0x1e1/0x210 rxrpc_input_packet+0x3f2/0x4d0 rxrpc_io_thread+0x243/0x410 ? __pfx_rxrpc_io_thread+0x10/0x10 kthread+0xcf/0xe0 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x24/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 </TASK>

El problema es que se llama desde AF_RXRPC mientras se mantiene el -\u0026gt;notify_lock, pero intenta tomar una referencia en la estructura afs_call para pasarla a una cola de trabajo; pero si afs_call ya est\u00e1 en cola, entonces tenemos una referencia extra\u00f1a que se debe poner... sin embargo, llamar a afs_put_call() puede volver a llamar a AF_RXRPC a trav\u00e9s de rxrpc_kernel_shutdown_call(), que podr\u00eda intentar tomar el -\u0026gt;notify_lock nuevamente. Sin embargo, este caso no es muy com\u00fan, por lo que se debe diferir a una cola de trabajo. El error se parece a algo como esto: ERROR: recursi\u00f3n de spinlock en CPU#0, krxrpcio/7001/1646 bloqueo: 0xffff888141399b30, .magic: dead4ead, .owner: krxrpcio/7001/1646, .owner_cpu: 0 CPU: 0 UID: 0 PID: 1646 Comm: krxrpcio/7001 No contaminado 6.12.0-rc2-build3+ #4351 Nombre del hardware: ASUS All Series/H97-PLUS, BIOS 2306 10/09/2014 Seguimiento de llamadas:  dump_stack_lvl+0x47/0x70 do_raw_spin_lock+0x3c/0x90 rxrpc_input_call_event+0xad/0x6b0 rxrpc_input_packet_on_conn+0x1e1/0x210 rxrpc_input_packet+0x3f2/0x4d0 rxrpc_io_thread+0x243/0x410 ?
