[OpenAFS-devel] RE: OpenAFS with Linux Kernel 2.4.18

[Neulinger, Nathan]

void osi_linux_unmask() {
    spin_lock_irq(&rxk_ListenerTask->sigmask_lock);
    sigemptyset(&rxk_ListenerTask->blocked);
    recalc_sigpending(rxk_ListenerTask);
    spin_unlock_irq(&rxk_ListenerTask->sigmask_lock);
}

/* unmask signals in rxk listener */
void afs_osi_UnmaskRxkSignals(){
#ifdef AFS_LINUX22_ENV
    osi_linux_unmask();
#endif
}

and here is where it's actually called:

#if defined(RXK_LISTENER_ENV)
    afs_warn("RxListener... ");
#ifndef UKERNEL
    afs_osi_UnmaskRxkSignals();
#endif
    /* cancel rx listener */
    osi_StopListener(); /* This closes rx_socket. */
    while (afs_termState =3D=3D AFSOP_STOP_RXK_LISTENER)
        afs_osi_Sleep(&afs_termState);
#endif
#else
    afs_termState =3D  AFSOP_STOP_COMPLETE;
#endif
    afs_warn("\n");


It eventually makes it's way to a LWP_DestroyProcess in rx/rx_lwp.c.=20

I'm checking to see if I can track down where exactly it's hanging, but
I figured this would help.
