2011-02-17ipv4: Move rcu_read_{lock,unlock}() into ip_route_output_slow().David S. Miller

2011-02-17ipv4: Simplify output route creation call sequence.David S. Miller
There's a lot of redundancy and unnecessary stack frames in the output route creation path. 1) Make __mkroute_output() return error pointers. 2) Eliminate ip_mkroute_output() entirely, made possible by #1. 3) Call __mkroute_output() directly and handling the returning error pointers in ip_route_output_slow().

2011-02-17RTC: Revert UIE emulation removalJohn Stultz
Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a018afcfba1d678062b62e46 - Remove UIE emulation 1daeddd5962acad1bea55e524fc0fa - Cleanup removed UIE emulation declaration b5cc8ca1c9c3a37eaddf709b2fd3e1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

2011-02-17RTC: Release mutex in error path of rtc_alarm_irq_enableUwe Kleine-König
On hardware that doesn't support alarm interrupts, rtc_alarm_irq_enable could return without releasing the ops_lock mutex. This was introduced in aa0be0f (RTC: Propagate error handling via rtc_timer_enqueue properly) This patch corrects the issue by only returning once the mutex is released.

2011-02-17tg3: Restrict phy ioctl accessMatt Carlson
If management firmware is present and the device is down, the firmware will assume control of the phy.

2011-02-17IB/qib: Prevent double completions after a timeout or RNR errorMike Marciniszyn
There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.

2011-02-17netfilter: tproxy: do not assign timewait sockets to skb->skFlorian Westphal
Assigning a socket in timewait state to skb->sk can trigger kernel oops, e.g. in nfnetlink_log, which does: if (skb->sk) { read_lock_bh(&skb->sk->sk_callback_lock); if (skb->sk->sk_socket && skb->sk->sk_socket->file) ... in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket is invalid. Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT, or xt_TPROXY must not assign a timewait socket to skb->sk. This does the latter. If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment, thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule. The 'SYN to TW socket' case is left unchanged -- we try to redirect to the listener socket.

2011-02-17block: revert block_dev read-only checkChuck Ebbert
This reverts commit 75f1dc0d076d ("block: check bdev_read_only() from blkdev_get()"). That commit added stricter checking to make sure devices that were being used read-only were actually opened in that mode. It turns out that the change breaks a bunch of kernel code that opens block devices. Affected systems include dm, md, and the loop device. Because strict checking for read-only opens of block devices was not done before this, the code that opens the devices was opening them read-write even if they were being used read-only. Auditing all that code will take time, and new userspace packages for dm, mdadm, etc. will also be required.

2011-02-16drm/nv40: fix tiling-related setup for a number of chipsetsBen Skeggs
Due to the default case handling the older chipsets, a bunch of the newer ones ended up having the wrong tiling regs used. This commit switches the default case to handle the newest chipsets. This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch them for C51 but traces of the NVIDIA binary driver show it being done there.

2011-02-16vfs: fix BUG_ON() in fs/namei.c:1461Linus Torvalds
When Al moved the nameidata_dentry_drop_rcu_maybe() call into the do_follow_link function in commit 844a391799c2 ("nothing in do_follow_link() is going to see RCU"), he mistakenly left the BUG_ON(inode != path->dentry->d_inode); behind. Which would otherwise be ok, but that BUG_ON() really needs to be _after_ dropping RCU, since the dentry isn't necessarily stable otherwise. So complete the code movement in that commit, and move the BUG_ON() into do_follow_link() too. This means that we need to pass in 'inode' as an argument (just for this one use), but that's a small thing. And eventually we may be confident enough in our path lookup that we can just remove the BUG_ON() and the unnecessary inode argument.
