2009-05-02ibft: fix the display of a few fields in the NIC attribute structure in sysfsAshutosh Naik
Fix the display of a few fields in the iBFT NIC attribute structure in sysfs. Ensure that, if the DHCP IP address and the subnet mask for the interface is present in the iBFT NIC structure, the corresponding entries are created in sysfs tree for the device. This would hence create the additional entries in the tree based on the iBFT table and would not delete any existing entries.

But NR_CPUS proportional isn't good calculation. In general, possibility of lock contention is proportional to the number of online cpus, not theorical maximum cpus (NR_CPUS). The current kernel has generic percpu-counter stuff. using it is right way. it makes code simplify and percpu_counter_read_positive() don't make underflow issue.

2009-05-02alpha: binfmt_aout fixIvan Kokshaysky
This fixes the problem introduced by commit 3bfacef412 (get rid of special-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaults when binfmt_aout built as module. That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

2009-05-02vgacon: return the upper half of 512 character fontsStefan Bader
Uwe Geuder noted that he gets random bitmaps on a text console if he tried to type extended characters (like the e acute). For him everything above unicode 0xa0 was corrupted. After some digging there seems to be a little culprit in vgacon since the beginning of ages (well git). The function vgacon_font_get will store the number of characters correctly in font->charcount but then calls to vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears. This happens on every switch between text consoles.

2009-05-02memcg: fix mem_cgroup_shrink_usage()Daisuke Nishimura
Current mem_cgroup_shrink_usage() has two problems. 1. It doesn't call mem_cgroup_out_of_memory and doesn't update last_oom_jiffies, so pagefault_out_of_memory invokes global OOM. 2. Considering hierarchy, shrinking has to be done from the mem_over_limit, not from the memcg which the page would be charged to. mem_cgroup_try_charge_swapin() does all of these things properly, so we use it and call cancel_charge_swapin when it succeeded. The name of "shrink_usage" is not appropriate for this behavior, so we change it too.

2009-05-02mm: close page_mkwrite racesNick Piggin
Change page_mkwrite to allow implementations to return with the page locked, and also change it's callers (in page fault paths) to hold the lock until the page is marked dirty. This allows the filesystem to have full control of page dirtying events coming from the VM. Rather than simply hold the page locked over the page_mkwrite call, we call page_mkwrite with the page unlocked and allow callers to return with it locked, so filesystems can avoid LOR conditions with page lock. The problem with the current scheme is this: a filesystem that wants to associate some metadata with a page as long as the page is dirty, will perform this manipulation in its ->page_mkwrite. It currently then must return with the page unlocked and may not hold any other locks (according to existing page_mkwrite convention). In this window, the VM could write out the page, clearing page-dirty. The filesystem has no good way to detect that a dirty pte is about to be attached, so it will happily write out the page, at which point, the filesystem may manipulate the metadata to reflect that the page is no longer dirty. It is not always possible to perform the required metadata manipulation in ->set_page_dirty, because that function cannot block or fail. The filesystem may need to allocate some data structure, for example. And the VM cannot mark the pte dirty before page_mkwrite, because page_mkwrite is allowed to fail, so we must not allow any window where the page could be written to if page_mkwrite does fail. This solution of holding the page locked over the 3 critical operations (page_mkwrite, setting the pte dirty, and finally setting the page dirty) closes out races nicely, preventing page cleaning for writeout being initiated in that window. This provides the filesystem with a strong synchronisation against the VM here. - Sage needs this race closed for ceph filesystem. - Trond for NFS (http://bugzilla.kernel.org/show_bug.cgi?id=12913). - I need it for fsblock. - I suspect other filesystems may need it too (eg. btrfs). - I have converted buffer.c to the new locking. Even simple block allocation under dirty pages might be susceptible to i_size changing under partial page at the end of file (we also have a buffer.c-side problem here, but it cannot be fixed properly without this patch). - Other filesystems (eg. NFS, maybe btrfs) will need to change their page_mkwrite functions themselves. [ This also moves page_mkwrite another step closer to fault, which should eventually allow page_mkwrite to be moved into ->fault, and thus avoiding a filesystem calldown and page lock/unlock cycle in __do_fault. ] [akpm@linux-foundation.org: fix derefs of NULL ->mapping] Cc: Sage Weil <sage@newdream.net> Cc: Trond Myklebust <trond.myklebust@fys.uio.no> Signed-off-by: Nick Piggin <npiggin@suse.de> Cc: Valdis Kletnieks <Valdis.Kletnieks@vt.edu> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We should validate each subpackage when extracted from the parent package, and not accept objects of the wrong type, since that will just cause the scanning to fail (likely with a kernel oops). This can only happen with a serious BIOS bug, and is accompanied by a warning something like this: ACPI Warning (nspredef-0949): \_SB_.PCI0.PEG4._PRT: Return Package type mismatch at index 0 - found Integer, expected Package [20090320] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

A regression was introduced in hg changeset 33810c734a0d, which resulted in a kernel panic whenever the device was disconnected from USB. The call to 4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a pointer to the v4l2_device instead of the au0828_dev structure.

2009-04-29V4L/DVB (11561a): move media after i2cGuennadi Liakhovetski
Currently drivers/media drivers are linked very early - directly after base, block, misc, and mfd and before ata, scsi, ide, input, firewire, usb, and i2c. This breaks static build of video4linux drivers, that use generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because during video4linux probing the v4l2-subdev core requires a struct i2c_adapter context, which cannot be satisfied before the i2c subsystem is initialised. Moving drivers/media after drivers/i2c fixes this problem. The best way to trigger action is by submitting a patch:-) So, let's see what comes out of it - on the one hand I don't see any reason why media has to be linked this early, and nobody was able to give me one yesterday as this problem has been discussed on linux-media, OTOH, maybe indeed it would be better to move i2c the whole way up above media, but that'd be much bigger of a change, I think. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-04-28e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo
After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

2009-04-28netfilter: revised locking for x_tablesStephen Hemminger
The x_tables are organized with a table structure and a per-cpu copies of the counters and rules. On older kernels there was a reader/writer lock per table which was a performance bottleneck. In 2.6.30-rc, this was converted to use RCU and the counters/rules which solved the performance problems for do_table but made replacing rules much slower because of the necessary RCU grace period. This version uses a per-cpu set of spinlocks and counters to allow to table processing to proceed without the cache thrashing of a global reader lock and keeps the same performance for table updates.
