2009-08-13Use correct NET_RX_* returns for atalk_rcv()Mark Smith1-11/+14
In all rx'd SKB cases, atalk_rcv() either eventually jumps to or falls through to the label out:, which returns numeric 0. Numeric 0 corresponds to NET_RX_SUCCESS, which is incorrect in failed SKB cases. This patch makes atalk_rcv() provide the correct returns by: o explicitly returning NET_RX_SUCCESS in the two success cases o having the out: label return NET_RX_DROP, instead of numeric 0 o making the failed SKB labels and processing more consistent with other _rcv() routines in the kernel, simplifying validation and removing a backwards goto Signed-off-by: Mark Smith <markzzzsmith@yahoo.com.au> Signed-off-by: David S.

2009-08-13f_phonet: use page-sized rather than MTU-sized RX buffersRémi Denis-Courmont1-26/+51
Instead of a large (physically) linear buffer, we generate a set of paged sk_buff, so no extra memory copy is involved. This removes high-order allocations and saves quite a bit of memory. Phonet MTU is 65541 bytes, so the two buffers were padded to 128 kilo-bytes each. Now, we create 17 page buffers, almost a 75% memory use reduction.

2009-08-10e1000e: fix potential NVM corruption on ICH9 with 8K bank sizeBruce Allan1-38/+12
The bank offset was being incorrectly calculated on ICH9 parts with a bank size of 8K (instead of the more common 4K bank) which would cause any NVM writes to be done on the wrong address after switching from bank 1 to bank 0. Additionally, assume we are meant to use bank 0 if a valid bank is not detected, and remove the unnecessary acquisition of the SW/FW/HW semaphore when writing to the shadow ram version of the NVM image.

2009-08-10ixgbe: Disable packet split only on FCoE queues in 82599Yi Zou2-16/+19
For 82599, packet split has to be disabled for FCoE direct data placement. However, this is only required on received queues allocated for FCoE. This patch adds a per ring flags to indicate if packet split is disabled on a per queue basis, particularly for FCoE, as packet split must be disabled for large receive using direct data placement (DDP).

2009-08-10tun: Extend RTNL lock coverage over whole ioctlHerbert Xu1-31/+19
As it is, parts of the ioctl runs under the RTNL and parts of it do not. The unlocked section is still protected by the BKL, but there can be subtle races. For example, Eric Biederman and Paul Moore observed that if two threads tried to create two tun devices on the same file descriptor, then unexpected results may occur. As there isn't anything in the ioctl that is expected to sleep indefinitely, we can prevent this from occurring by extending the RTNL lock coverage. This also allows to get rid of the BKL. Finally, I changed tun_get_iff to take a tun device in order to avoid calling tun_put which would dead-lock as it also tries to take the RTNL lock.

2009-08-10fec: fix FEC driver packet transmission breakageGreg Ungerer1-4/+5
Commit f0b3fbeae11a526c3d308b691684589ee37c359b ("FEC Buffer rework") breaks transmission of packets where the skb data buffer is not memory aligned according to FEC_ALIGNMENT. It incorrectly passes to dma_sync_single() the buffer address directly from the skb, instead of the address calculated for use (which may be the skb address or one of the bounce buffers). It seems there is no use converting the cpu address of the buffer to a physical either, since dma_map_single() expects the cpu address and will return the dma address to use in the descriptor. So remove the use of __pa() on the buffer address as well. This patch is against 2.6.30-rc5. This breakage is a regression over 2.6.30, which does not have this problem.

2009-08-09perf_counter: Fix/complete ftrace event records samplingFrederic Weisbecker7-41/+126
This patch implements the kernel side support for ftrace event record sampling. A new counter sampling attribute is added: PERF_SAMPLE_TP_RECORD which requests ftrace events record sampling. In this case if a PERF_TYPE_TRACEPOINT counter is active and a tracepoint fires, we emit the tracepoint binary record to the perfcounter event buffer, as a sample. Result, after setting PERF_SAMPLE_TP_RECORD attribute from perf record: perf record -f -F 1 -a -e workqueue:workqueue_execution perf report -D 0x21e18 [0x48]: event: 9 . . ... raw event: size 72 bytes . 0000: 09 00 00 00 01 00 48 00 d0 c7 00 81 ff ff ff ff ......H........ . 0010: 0a 00 00 00 0a 00 00 00 21 00 00 00 00 00 00 00 ........!...... . 0020: 2b 00 01 02 0a 00 00 00 0a 00 00 00 65 76 65 6e +...........eve . 0030: 74 73 2f 31 00 00 00 00 00 00 00 00 0a 00 00 00 ts/1........... . 0040: e0 b1 31 81 ff ff ff ff ....... . 0x21e18 [0x48]: PERF_EVENT_SAMPLE (IP, 1): 10: 0xffffffff8100c7d0 period: 33 The raw ftrace binary record starts at offset 0020.

For that we need to have an instant access to the perf counter attribute. This is a matter of a flag to add in the struct ftrace_event. - Take care of the events recursivity! Don't ever try to record a lock event for example, it seems some locking is used in the profiling fast path and lead to a tracing recursivity. That will be fixed using raw spinlock or recursivity protection. - [...] - Profit! :-) Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Li Zefan <lizf@cn.fujitsu.com> Cc: Tom Zanussi <tzanussi@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Pekka Enberg <penberg@cs.helsinki.fi> Cc: Gabriel Munteanu <eduard.munteanu@linux360.ro> Cc: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-08-09perf_counter, ftrace: Fix perf_counter integrationPeter Zijlstra2-28/+88
Adds possible second part to the assign argument of TP_EVENT(). TP_perf_assign( __perf_count(foo); __perf_addr(bar); ) Which, when specified make the swcounter increment with @foo instead of the usual 1, and report @bar for PERF_SAMPLE_ADDR (data address associated with the event) when this triggers a counter overflow.

2009-08-09KVM: Avoid redelivery of edge interrupt before next edgeGleb Natapov1-5/+5
The check for an edge is broken in current ioapic code. ioapic->irr is cleared on each edge interrupt by ioapic_service() and this makes old_irr != ioapic->irr condition in kvm_ioapic_set_irq() to be always true. The patch fixes the code to properly recognise edge. Some HW emulation calls set_irq() without level change. If each such call is propagated to an OS it may confuse a device driver. This is the case with keyboard device emulation and Windows XP x64 installer on SMP VM. Each keystroke produce two interrupts (down/up) one interrupt is submitted to CPU0 and another to CPU1. This confuses Windows somehow and it ignores keystrokes. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

Some applications/hardware combinations are triggering the message "failed to acquire vblank counter" to be issued up to 20 times a second, which makes it both useless and dangerous, as this may hide other important messages. This changes makes it only appear when people are debugging.

2009-08-09drm: When adding probed modes, preserve duplicate mode typesKeith Packard1-0/+2
The code which takes probed modes and adds them to a connector eliminates duplicate modes by comparing them using drm_mode_equal. That function doesn't consider the type bits, which means that any modes which differ only in the type field will be lost. One of the bits in the mode->type field is the DRM_MODE_TYPE_PREFERRED bit. If the mode with that bit is lost, then higher level code will not know which mode to select, causing a random mode to be used instead. This patch simply merges the two mode type bits together; that seems reasonable to me, but perhaps only a subset of the bits should be used? None of these can be user defined as they all come from looking at just the hardware. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

When the process exits we don't have to run new cputimer nor use running one (as it not accounts when tsk->exit_state != 0) to get process CPU times. As there is only one thread we can just use CPU times fields from task and signal structs.
