2012-06-16tile: fix bug in get_user() for 4-byte valuesChris Metcalf1-1/+1
The definition of 32-bit values in the 64-bit tilegx architecture is that they should be sign-extended regardless of whether they are considered signed or unsigned by the compiler. Accordingly, we need to use an "ld4s" rather than "ld4u" to load and sign-extend for get_user(). This fixes glibc bug 14238 (see http://sourceware.org/bugzilla), introduced during the 3.5 merge window. Signed-off-by: Chris Metcalf <[email protected]>

2012-06-16printk: use mutex lock to stop syslog_seq from going wildYuanhan Liu1-2/+11
Although syslog_seq and log_next_seq stuff are protected by logbuf_lock spin log, it's not enough. Say we have two processes A and B, and let syslog_seq = N, while log_next_seq = N + 1, and the two processes both come to syslog_print at almost the same time. And No matter which process get the spin lock first, it will increase syslog_seq by one, then release spin lock; thus later, another process increase syslog_seq by one again. In this case, syslog_seq is bigger than syslog_next_seq. And latter, it would make: wait_event_interruptiable(log_wait, syslog != log_next_seq) don't wait any more even there is no new write comes. Thus it introduce a infinite loop reading. I can easily see this kind of issue by the following steps: # cat /proc/kmsg # at meantime, I don't kill rsyslog # So they are the two processes. # xinit # I added drm.debug=6 in the kernel parameter line, # so that it will produce lots of message and let that # issue happen It's 100% reproducable on my side. And my disk will be filled up by /var/log/messages in a quite short time. So, introduce a mutex_lock to stop syslog_seq from going wild just like what devkmsg_read() does. It does fix this issue as expected. v2: use mutex_lock_interruptiable() instead (comments from Kay) Signed-off-by: Yuanhan Liu <[email protected]> Reviewed-by: Fengguang Wu <[email protected]> Acked-By: Kay Sievers <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2012-06-16Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"Daniel Vetter1-1/+6
This reverts commit 092945e11c5b84f66dd08f0b87fb729715d377bc. This commit prevents a DP screen from properly training the link. Oddly enough it works, once the machine has been warm-booted with an older kernel. According to DP docs this _should_ have been the right precharge time. Also, the commit that originally introduces this was just general snb DP enabling and didn't mention any specific reason for this special value. Whatever, trust the reporter that this makes things worse and let's just revert it. v2: Less spelling fail.

2012-06-15swap: fix shmem swapping when more than 8 areasHugh Dickins2-11/+9
Minchan Kim reports that when a system has many swap areas, and tmpfs swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read back the page cannot locate it, and the read fails with -ENOMEM. Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next.

2012-06-15ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_routeThomas Graf3-12/+24
/proc/net/ipv6_route reflects the contents of fib_table_hash. The proc handler is installed in ip6_route_net_init() whereas fib_table_hash is allocated in fib6_net_init() _after_ the proc handler has been installed. This opens up a short time frame to access fib_table_hash with its pants down. fib6_init() as a whole can't be moved to an earlier position as it also registers the rtnetlink message handlers which should be registered at the end. Therefore split it into fib6_init() which is run early and fib6_init_late() to register the rtnetlink message handlers.

2012-06-15net: remove skb_orphan_try()Eric Dumazet4-31/+3
Orphaning skb in dev_hard_start_xmit() makes bonding behavior unfriendly for applications sending big UDP bursts : Once packets pass the bonding device and come to real device, they might hit a full qdisc and be dropped. Without orphaning, the sender is automatically throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming sk_sndbuf is not too big) We could try to defer the orphaning adding another test in dev_hard_start_xmit(), but all this seems of little gain, now that BQL tends to make packets more likely to be parked in Qdisc queues instead of NIC TX ring, in cases where performance matters.

2012-06-15bnx2x: fix panic when TX ring is fullEric Dumazet1-5/+3
There is a off by one error in the minimal number of BD in bnx2x_start_xmit() and bnx2x_tx_int() before stopping/resuming tx queue. A full size GSO packet, with data included in skb->head really needs (MAX_SKB_FRAGS + 4) BDs, because of bnx2x_tx_split() This error triggers if BQL is disabled and heavy TCP transmit traffic occurs. bnx2x_tx_split() definitely can be called, remove a wrong comment.

2012-06-15kmsg - kmsg_dump() use iterator to receive log buffer contentKay Sievers6-137/+258
Provide an iterator to receive the log buffer content, and convert all kmsg_dump() users to it. The structured data in the kmsg buffer now contains binary data, which should no longer be copied verbatim to the kmsg_dump() users. The iterator should provide reliable access to the buffer data, and also supports proper log line-aware chunking of data while iterating.
