* tty: Fix race in the flush for some ldiscsAlan Cox2009-01-151-1/+1
| | | | | | | | | | | | | If you issue an ioctl to flush a tty as the line discipline is changing or otherwise unplugged you can get a crash. The bug is very old but the rest of the BKL lock dropping and some very "good" luck on Ingo's part caught an example. Use the correct ldisc_ref form so that we wait for the ldisc change to complete and then flush Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * hvc_console: Do not set low_latency when using interruptsMilton Miller2009-01-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hvc_console is setting low_latency unconditionally, but some clients are interrupt driven and will call hvc_poll from irq context. This will cause tty_flip_buffer_push to be called from irq context, and it very clearly states it must not be called from IRQ when low_latency is specified. Looking back through history: v2.6.16-rc1 via 33f0f88f1c51ae5c2d593d26960c760ea154c2e2 [PATCH] TTY layer buffering revamp added this new api. v2.6.16-rc3 via 8977d929e49021d9a6e031310aab01fa72f849c2 [PATCH] tty buffering stall fix claims to fix a stall discovered with hvc_console v2.6.16-rc5 via fb5c594c2acc441f0d2d8f457484a0e0e9285db3 [PATCH] Fix race condition in hvc console. said set this flag to avoid a stall problem, and was merged through the powerpc arch tree.

This patch fixes this by copying the missing fields. As this change to early_serial_setup() doesn't need an initialized spinlock in the uart_port struct any longer, we can drop the spinlock initialization in the superio driver.

In that case, the sender side will create an ipoib_neigh and issue a path request with the old GID first. When skb->dst->neighbour->ha changes due to ARP refresh, this ipoib_neigh will not be added to the path->list of the path of the new GID, because the ipoib_neigh already exists. It will not have an AH either, because of sender-side failover. Therefore, it will not get an AH when the path is resolved. The solution here is to compare GIDs in ipoib_start_xmit() even if neigh->ah is invalid. Comparing with an uninitialized value of neigh->dgid should be fine, since a spurious match is harmless (and astronomically unlikely too).
