2008-08-01ALSA: trident - pause s/pdif outputPierre Ossman
Commit 981bcead3f2279a1ec6fb5f2c57aff79ed61a700 upstream. Stop the S/PDIF DMA engine and output when the device is told to pause. It will keep on looping the current buffer contents if this isn't done.

commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 upstream cdrom_read_capacity() will blindly return the capacity from the device without sanity-checking it. This later causes code in fs/buffer.c to oops. Fix this by checking that the device is telling us sensible things.

2008-08-01markers: fix duplicate modpost entryMathieu Desnoyers
commit: d35cb360c29956510b2fe1a953bd4968536f7216 When a kernel was rebuilt, the previous Module.markers was not cleared. It caused markers with different format strings to appear as duplicates when a markers was changed. This problem is present since scripts/mod/modpost.c started to generate Module.markers, commit b2e3e658b344c6bcfb8fb694100ab2f2b5b2edb0 It therefore applies to 2.6.25, 2.6.26 and linux-next. I merely merged the patches from Roland, Wenji and Takashi here. Credits to Roland McGrath <roland@redhat.com> Wenji Huang <wenji.huang@oracle.com> and Takashi Nishiie <t-nishiie@np.css.fujitsu.com> for providing the individual fixes. - Changelog : - Integrated Takashi's Makefile modification to clear Module.markers upon make clean.

2008-08-01pata_atiixp: Don't disableAlan Cox
Commit 05177f178efe1459d2d0ac05430027ba201889a4 upstream pata_atiixp: Don't disable A couple of distributions (Fedora, Ubuntu) were having weird problems with the ATI IXP series PATA controllers being reported as simplex. At the heart of the problem is that both distros ignored the recommendations to load pata_acpi and ata_generic *AFTER* specific host drivers. The underlying cause however is that if you D3 and then D0 an ATI IXP it helpfully throws away some configuration and won't let you rewrite it. Add checks to ata_generic and pata_acpi to pin ATIIXP devices. Possibly the real answer here is to quirk them and pin them, but right now we can't do that before they've been pcim_enable()'d by a driver. I'm indebted to David Gero for this. His bug report not only reported the problem but identified the cause correctly and he had tested the right values to prove what was going on [If you backport this for 2.6.24 you will need to pull in the 2.6.25 removal of the bogus WARN_ON() in pcim_enagle] Signed-off-by: Alan Cox <alan@redhat.com> Tested-by: David Gero <davidg@havidave.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

[ Upstream commit b7c2a75725dee9b5643a0aae3a4cb47f52e00a49 ] We're calling request_irq() with a IRQs disabled. No straightforward fix exists because we want to enable these IRQs and setup state atomically before getting into the IRQ handler the first time. What happens now is that we mark the VIRQ to not be automatically enabled by request_irq(). Then we make explicit enable_irq() calls when we grab the LDC channel. This way we don't need to call request_irq() illegally under the LDC channel lock any more. Bump LDC version and release date. Signed-off-by: David S.

2008-08-01tcp: Clear probes_out more aggressively in tcp_ack().David S. Miller
[ Upstream commit 4b53fb67e385b856a991d402096379dab462170a ] This is based upon an excellent bug report from Eric Dumazet. tcp_ack() should clear ->icsk_probes_out even if there are packets outstanding. Otherwise if we get a sequence of ACKs while we do have packets outstanding over and over again, we'll never clear the probes_out value and eventually think the connection is too sick and we'll reset it. This appears to be some "optimization" added to tcp_ack() in the 2.4.x timeframe. In 2.2.x, probes_out is pretty much always cleared by tcp_ack(). Here is Eric's original report: ---------------------------------------- Apparently, we can in some situations reset TCP connections in a couple of seconds when some frames are lost. In order to reproduce the problem, please try the following program on linux-2.6.25.* Setup some iptables rules to allow two frames per second sent on loopback interface to tcp destination port 12000 iptables -N SLOWLO iptables -A SLOWLO -m hashlimit --hashlimit 2 --hashlimit-burst 1 --hashlimit-mode dstip --hashlimit-name slow2 -j ACCEPT iptables -A SLOWLO -j DROP iptables -A OUTPUT -o lo -p tcp

2008-08-01vmlinux.lds: move __attribute__((__cold__)) functions back into final .text ↵Jan Beulich
section commit fb5e2b379732e1a6ea32392980bb42e0212db842 upstream Due to the addition of __attribute__((__cold__)) to a few symbols without adjusting the linker scripts, those symbols currently may end up outside the [_stext,_etext) range, as they get placed in .text.unlikely by (at least) gcc 4.3.0. This may confuse code not only outside of the kernel, symbol_put_addr()'s BUG() could also trigger. Hence we need to add .text.unlikely (and for future uses of __attribute__((__hot__)) also .text.hot) to the TEXT_TEXT() macro. Issue observed by Lukas Lipavsky.

2008-08-01isofs: fix minor filesystem corruptionAdam Greenblatt
commit c0a1633b6201ef79e31b7da464d44fdf5953054d upstream Some iso9660 images contain files with rockridge data that is either incorrect or incompletely parsed. Prior to commit f2966632a134e865db3c819346a1dc7d96e05309 ("[PATCH] rock: handle directory overflows") (included with kernel 2.6.13) the kernel ignored the rockridge data for these files, while still allowing the files to be accessed under their non-rockridge names. That commit inadvertently changed things so that files with invalid rockridge data could not be accessed at all. (I ran across the problem when comparing some old CDs with hard disk copies I had made long ago under kernel 2.4: a few of the files on the hard disk copies were no longer visible on the CDs.) This change reverts to the pre-2.6.13 behavior.

commit b48d380541f634663b71766005838edbb7261685 upstream When quota structure is going to be dropped and it is dirty, quota code tries to write it.

[ Upstream commit 47112e25da41d9059626033986dc3353e101f815 ] This patch clamps the cscov setsockopt values to a maximum of 0xFFFF. Setsockopt values greater than 0xffff can cause an unwanted wrap-around. Further, IPv6 jumbograms are not supported (RFC 3838, 3.5), so that values greater than 0xffff are not even useful.

[ Upstream commit fe833fca2eac6b3d3ad5e35f44ad4638362f1da8 ] When generating the ip header for the transformed packet we just copy the frag_off field of the ip header from the original packet to the ip header of the new generated packet. If we receive a packet as a chain of fragments, all but the last of the new generated packets have the IP_MF flag set. We have to mask the frag_off field to only keep the IP_DF flag from the original packet.

commit ee3ece830f6db9837f7ac67008f532a8c1e755f4 upstream. Due to a possible deadlock, the waking of the softirq was pushed outside of the hrtimer base locks. See commit 0c96c5979a522c3323c30a078a70120e29b5bdbc Unfortunately this allows the task to migrate after setting up the softirq and raising it. Since softirqs run a queue that is per-cpu we may raise the softirq on the wrong CPU and this will keep the queued softirq task from running. To solve this issue, this patch disables preemption around the releasing of the hrtimer lock and raising of the softirq.

commit f31ad92f34913043cf008d6e479e92dfbaf02df1 upstream This patch is a bugfix for how defio handles multiple processes manipulating the same framebuffer. Thanks to Bernard Blackham for identifying this bug. It occurs when two applications mmap the same framebuffer and concurrently write to the same page. Normally, this doesn't occur since only a single process mmaps the framebuffer. The symptom of the bug is that the mapping applications will hang. The cause is that defio incorrectly tries to add the same page twice to the pagelist. The solution I have is to walk the pagelist and check for a duplicate before adding. Since I needed to walk the pagelist, I now also keep the pagelist in sorted order.

This made me realize that ov7670_read's semantics were rather confusing; it both fills in 'value' with the result, and returns it. This is goes against general kernel convention; so rather than fixing callers, let's fix the function. This makes ov7670_read return <0 in the case of an error, and 0 upon success.

Yeah, it's possible that a caller of kmem_cache_alloc() -> slab_alloc() can be migrated on another CPU right after local_irq_restore() and before memset(). The inital cpu can become offline in the mean time (or a migration is a consequence of the CPU going offline) so its 'kmem_cache_cpu' structure gets freed ( slab_cpuup_callback).

commit 96a8e13ed44e380fc2bb6c711d74d5ba698c00b2 upstream Kernel Bugzilla #11063 points out that on some architectures (e.g. x86_32) exec'ing an ELF without a PT_GNU_STACK program header should default to an executable stack; but this got broken by the unlimited argv feature because stack vma is now created before the right personality has been established: so breaking old binaries using nested function trampolines. Therefore re-evaluate VM_STACK_FLAGS in setup_arg_pages, where stack vm_flags used to be set, before the mprotect_fixup.

Upstream commit 84ebe1c: Lost connections was reported by Thomas Bätzler (running 2.6.25 kernel) on the netfilter mailing list (see the thread "Weird nat/conntrack Problem with PASV FTP upload"). He provided tcpdump recordings which helped to find a long lingering bug in conntrack. In TCP connection tracking, checking the lower bound of valid ACK could lead to mark valid packets as INVALID because: - We have got a "higher or equal" inequality, but the test checked the "higher" condition only; fixed. - If the packet contains a SACK option, it could occur that the ACK value was before the left edge of our (S)ACK "window": if a previous packet from the other party intersected the right edge of the window of the receiver, we could move forward the window parameters beyond accepting a valid ack. Therefore in this patch we check the rightmost SACK edge instead of the ACK value in the lower bound of valid (S)ACK test.

commit f15e39739a1d7dfaa2173a91707a74c11a246648 upstream Remove dev_info call on disconnect. The sisusb_dev pointer may have been set to zero by sisusb_delete at this point causing an oops. The message does not provide any extra information over the standard USB subsystem output so removing it does not affect functionality.
