efc968d Linus Torvalds 09 October 2008, 21:04:54 UTC Don't allow splice() to files opened with O_APPEND This is debatable, but while we're debating it, let's disallow the combination of splice and an O_APPEND destination. It's not entirely clear what the semantics of O_APPEND should be, and POSIX apparently expects pwrite() to ignore O_APPEND, for example. So we could make up any semantics we want, including the old ones. But Miklos convinced me that we should at least give it some thought, and that accepting writes at arbitrary offsets is wrong at least for IS_APPEND() files (which always have O_APPEND set, even if the reverse isn't true: you can obviously have O_APPEND set on a regular file). So disallow O_APPEND entirely for now. I doubt anybody cares, and this way we have one less gray area to worry about.

70096a5 Matt Mackall 08 October 2008, 19:51:57 UTC SLOB: fix bogus ksize calculation fix This fixes the previous fix, which was completely wrong on closer inspection. This version has been manually tested with a user-space test harness and generates sane values. A nearly identical patch has been boot-tested. The problem arose from changing how kmalloc/kfree handled alignment padding without updating ksize to match. This brings it in sync.

58ec3b4 Herbert Xu 07 October 2008, 22:50:03 UTC net: Fix netdev_run_todo dead-lock Benjamin Thery tracked down a bug that explains many instances of the error unregister_netdevice: waiting for %s to become free. Usage count = %d It turns out that netdev_run_todo can dead-lock with itself if a second instance of it is run in a thread that will then free a reference to the device waited on by the first instance. The problem is really quite silly. We were trying to create parallelism where none was required. As netdev_run_todo always follows a RTNL section, and that todo tasks can only be added with the RTNL held, by definition you should only need to wait for the very ones that you've added and be done with it. There is no need for a second mutex or spinlock. This is exactly what the following patch does. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

53240c2 Ali Saidi 07 October 2008, 22:31:19 UTC tcp: Fix possible double-ack w/ user dma From: Ali Saidi <saidi@engin.umich.edu> When TCP receive copy offload is enabled it's possible that tcp_rcv_established() will cause two acks to be sent for a single packet. In the case that a tcp_dma_early_copy() is successful, copied_early is set to true which causes tcp_cleanup_rbuf() to be called early which can send an ack. Further along in tcp_rcv_established(), __tcp_ack_snd_check() is called and will schedule a delayed ACK. If no packets are processed before the delayed ack timer expires the packet will be acked twice. Signed-off-by: David S. Miller <davem@davemloft.net> 07 October 2008, 22:31:19 UTC
b6c40d6 Patrick McHardy 07 October 2008, 22:26:48 UTC net: only invoke dev->change_rx_flags when device is UP Jesper Dangaard Brouer <hawk@comx.dk> reported a bug when setting a VLAN device down that is in promiscous mode: When the VLAN device is set down, the promiscous count on the real device is decremented by one by vlan_dev_stop(). When removing the promiscous flag from the VLAN device afterwards, the promiscous count on the real device is decremented a second time by the vlan_change_rx_flags() callback. The root cause for this is that the ->change_rx_flags() callback is invoked while the device is down. The synchronization is meant to mirror the behaviour of the ->set_rx_mode callbacks, meaning the ->open function is responsible for doing a full sync on open, the ->close() function is responsible for doing full cleanup on ->stop() and ->change_rx_flags() is meant to do incremental changes while the device is UP. Only invoke ->change_rx_flags() while the device is UP to provide the intended behaviour.

e683b42 Haavard Skinnemoen 06 October 2008, 18:09:53 UTC atmel-mci: Initialize BLKR before sending data transfer command The atmel-mci driver sometimes fails data transfers like this: mmcblk0: error -5 transferring data end_request: I/O error, dev mmcblk0, sector 2749769 end_request: I/O error, dev mmcblk0, sector 2749777 It turns out that this might be caused by the BLKR register (which contains the block size and the number of blocks being transfered) being initialized too late. This patch moves the initialization of BLKR so that it contains the correct value before the block transfer command is sent. This error is difficult to reproduce, but if you insert a long delay (mdelay(10) or thereabouts) between the calls to atmci_start_command() and atmci_submit_data(), all transfers seem to fail without this patch, while I haven't seen any failures with this patch.

e84956f Rafael J. Wysocki 06 October 2008, 09:59:29 UTC x86 ACPI: Blacklist two HP machines with buggy BIOSes There is a bug in the BIOSes of some HP boxes with AMD Turions which connects IO-APIC pins with ACPI thermal trip points in such a way that if the state of the IO-APIC is not as expected by the (buggy) BIOS, the thermal trip points are set to insanely low values (usually all of them become 16 degrees Celsius). As a result, thermal throttling kicks in and knock the system down to its shoes. Unfortunately some of the recent IO-APIC changes made the bug show up. To prevent this from happening, blacklist machines that are known to be affected (nx6115 and 6715b in this particular case). This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as a regression from 2.6.26. On my box it was caused by: commit 691874fa96d6349a8b60f8ea9c2bae52ece79941 Author: Maciej W.

3040a6d Paul Moore 03 October 2008, 14:51:15 UTC selinux: Fix an uninitialized variable BUG/panic in selinux_secattr_to_sid() At some point during the 2.6.27 development cycle two new fields were added to the SELinux context structure, a string pointer and a length field. The code in selinux_secattr_to_sid() was not modified and as a result these two fields were left uninitialized which could result in erratic behavior, including kernel panics, when NetLabel is used. This patch fixes the problem by fully initializing the context in selinux_secattr_to_sid() before use and reducing the level of direct context manipulation done to help prevent future problems.

d3d238c Heiko Carstens 03 October 2008, 19:54:59 UTC [S390] nohz: Fix __udelay. This fixes a regression that came with 934b2857cc576ae53c92a66e63fce7ddcfa74691 ("[S390] nohz/sclp: disable timer on synchronous waits."). If udelay() gets called from a disabled context it sets the clock comparator to a value where it expects the next interrupt. When the interrupt happens the clock comparator gets not reset and therefore the interrupt condition doesn't get cleared. The result is an endless timer interrupt loop. In addition this patch fixes also the following: rcutorture reveals that our __udelay implementation is still buggy, since it might schedule tasklets, but prevents their execution: NOHZ: local_softirq_pending 42 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 142 NOHZ: local_softirq_pending 02 To fix this we make sure that only the clock comparator interrupt is enabled when the enabled wait psw is loaded. Also no code gets called anymore which might schedule tasklets.

At the same time, the warning was also insufficient, since it didn't check that interrupts were enabled. The proper debug function to use for something that can sleep and wants a warning if it's called in the wrong context is 'might_sleep()'.

b5ff7df Linus Torvalds 03 October 2008, 01:52:51 UTC Check mapped ranges on sysfs resource files This is loosely based on a patch by Jesse Barnes to check the user-space PCI mappings though the sysfs interfaces. Quoting Jesse's original explanation: It's fairly common for applications to map PCI resources through sysfs. However, with the current implementation, it's possible for an application to map far more than the range corresponding to the resourceN file it opened. This patch plugs that hole by checking the range at mmap time, similar to what is done on platforms like sparc64 in their lower level PCI remapping routines. It was initially put together to help debug the e1000e NVRAM corruption problem, since we initially thought an X driver might be walking past the end of one of its mappings and clobbering the NVRAM. It now looks like that's not the case, but doing the check is still important for obvious reasons. and this version of the patch differs in that it uses a helper function to clarify the code, and does all the checks in pages (instead of bytes) in order to avoid overflows when doing "<< PAGE_SHIFT" etc. Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 03 October 2008, 01:52:51 UTC
