site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com User-agent: Microsoft-Entourage/11.1.0.040913 Stéphane, Please file a bug about this. You may have noticed that support for debugging the socket locking )available on PPC to keep the link register) is not available in xnu-792.1.5 for x86. The content of those "so_reserved" fields are floating on that architecture in that kernel. I'd like to take the opportunity to remind you guys to please do not rely on these internal structures in any of your kexts, as they WILL change and are not part of the supported KPIs.

Is there not a bug in udp_lock when it comes to x86 architecture:
int udp_lock(so, refcount, debug) struct socket *so; int refcount, debug; { int lr_saved; #ifdef __ppc__ if (debug == 0) { __asm__ volatile("mflr %0" : "=r" (lr_saved)); } else lr_saved = debug; #endif
if (so->so_pcb) { lck_mtx_assert(((struct inpcb *)so->so_pcb)->inpcb_mtx, LCK_MTX_ASSERT_NOTOWNED); lck_mtx_lock(((struct inpcb *)so->so_pcb)->inpcb_mtx); } else { panic("udp_lock: so=%x NO PCB! lr=%x\n", so, lr_saved); lck_mtx_assert(so->so_proto->pr_domain->dom_mtx, LCK_MTX_ASSERT_NOTOWNED); lck_mtx_lock(so->so_proto->pr_domain->dom_mtx); }
if (refcount) so->so_usecount++;
so->reserved3= lr_saved; return (0); }
lr_saved is not initialized as far as I can see if __ppc__ is not defined.
There's no warning in gcc when building on a x86?
