2009-02-15kbuild: create the source symlink earlier in the objdirAndi Kleen
It's useful to already have the source symlink in a objdir when one just runs make *config. Then one can do mkdir obj-allyes cd obj-allyes make -C ../sourcedir O=$(pwd) allyesconfig ./source/scripts/config --disable debug_info make CC=icecc -j18 without having to interrupt the make first just to get the source symlink.

An oops dump also contains the register values. This patch parses these for (32 bit) x86, and then annotates the disassembly with these values; this helps in analysis of the oops by the developer, for example, NULL pointer or other pointer bugs show up clearly this way.

2009-02-15kbuild: add sys_* entries for syscalls in tagsRabin Vincent
Currently, it is no longer possible to use the tags file to jump to system call function definitions with sys_foo, because the definitions are obscured by use of the SYSCALL_DEFINE* macros. This patch adds the appropriate option to ctags to make it see through the macro. Also, it adds the ENTRY() work already done for Exuberant to Emacs too.

2009-02-15kbuild: add vmlinux to kernel rpmJosh Hunt
We are building an automated system to test kernels weekly and need to provide an rpm to our QA dept. We would like to use the ability to create kernel rpms already in the kernel's Makefile, but need the vmlinux file included in the rpm for later debugging. This patch adds a compressed vmlinux to the kernel rpm when doing a make rpm-pkg or binrpm-pkg and upon install places the vmlinux file in /boot.

2009-02-13User namespaces: Only put the userns when we unhash the uidSerge E. Hallyn
uids in namespaces other than init don't get a sysfs entry. For those in the init namespace, while we're waiting to remove the sysfs entry for the uid the uid is still hashed, and alloc_uid() may re-grab that uid without getting a new reference to the user_ns, which we've already put in free_user before scheduling remove_user_sysfs_dir().

Change HP dv7 quirk: although reported to work with hp-m4 model (https://bugzilla.novell.com/show_bug.cgi?id=445321), the original report doesn't contain info about testing of internal microphone. Recently I received a report about internal mic not working (https://qa.mandriva.com/show_bug.cgi?id=44855#c193), this must be related with the forced line in on pin 0x0e done with hp-m4 model. Thus change the current quirk from STAC_HP_M4 to STAC_HP_DV5, later reported to be fixed on a provided kernel with this change (https://qa.mandriva.com/show_bug.cgi?id=44855#c196).

2009-02-12net: don't use in_atomic() in gfp_any()Andrew Morton
The problem is that in_atomic() will return false inside spinlocks if CONFIG_PREEMPT=n. This will lead to deadlockable GFP_KERNEL allocations from spinlocked regions. Secondly, if CONFIG_PREEMPT=y, this bug solves itself because networking will instead use GFP_ATOMIC from this callsite. Hence we won't get the might_sleep() debugging warnings which would have informed us of the buggy callsites. Solve both these problems by switching to in_interrupt(). Now, if someone runs a gfp_any() allocation from inside spinlock we will get the warning if CONFIG_PREEMPT=y. I reviewed all callsites and most of them were too complex for my little brain and none of them documented their interface requirements. I have no idea what this patch will do.

2009-02-12Fix page writeback thinko, causing Berkeley DB slowdownNick Piggin
A bug was introduced into write_cache_pages cyclic writeout by commit 31a12666d8f0c22235297e1c1575f82061480029 ("mm: write_cache_pages cyclic fix"). The intention (and comments) is that we should cycle back and look for more dirty pages at the beginning of the file if there is no more work to be done. But the !done condition was dropped from the test. This means that any time the page writeout loop breaks (eg. due to nr_to_write == 0), we will set index to 0, then goto again. This will set done_index to index, then find done is set, so will proceed to the end of the function. When updating mapping->writeback_index for cyclic writeout, we now use done_index == 0, so we're always cycling back to 0. This seemed to be causing random mmap writes (slapadd and iozone) to start writing more pages from the LRU and writeout would slowdown, and caused bugzilla entry http://bugzilla.kernel.org/show_bug.cgi?id=12604 about Berkeley DB slowing down dramatically. With this patch, iozone random write performance is increased nearly 5x on my system (iozone -B -r 4k -s 64k -s 512m -s 1200m on ext2).

2009-02-11nbd: fix I/O hang on disconnected nbdsPaul Clements
Fix a problem that causes I/O to a disconnected (or partially initialized) nbd device to hang indefinitely. To reproduce: # ioctl NBD_SET_SIZE_BLOCKS /dev/nbd23 514048 # dd if=/dev/nbd23 of=/dev/null bs=4096 count=1 ...hangs... This can also occur when an nbd device loses its nbd-client/server connection. Although we clear the queue of any outstanding I/Os after the client/server connection fails, any additional I/Os that get queued later will hang. This bug may also be the problem reported in this bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12277 Testing would need to be performed to determine if the two issues are the same. This problem was introduced by the new request handling thread code ("NBD: allow nbd to be used locally", 3/2008), which entered into mainline around 2.6.25. The fix, which is fairly simple, is to restore the check for lo->sock being NULL in do_nbd_request. This causes I/O to an uninitialized nbd to immediately fail with an I/O error, as it did prior to the introduction of this bug.

2009-02-11mm: rearrange exit_mmap() to unlock before arch_exit_mmapJeremy Fitzhardinge
Christophe Saout reported [in precursor to: http://marc.info/?l=linux-kernel&m=123209902707347&w=4]: > Note that I also some a different issue with CONFIG_UNEVICTABLE_LRU. > Seems like Xen tears down current->mm early on process termination, so > that __get_user_pages in exit_mmap causes nasty messages when the > process had any mlocked pages. (in fact, it somehow manages to get into > the swapping code and produces a null pointer dereference trying to get > a swap token) Jeremy explained: Yes. In the normal case under Xen, an in-use pagetable is "pinned", meaning that it is RO to the kernel, and all updates must go via hypercall (or writes are trapped and emulated, which is much the same thing). An unpinned pagetable is not currently in use by any process, and can be directly accessed as normal RW pages. As an optimisation at process exit time, we unpin the pagetable as early as possible (switching the process to init_mm), so that all the normal pagetable teardown can happen with direct memory accesses. This happens in exit_mmap() -> arch_exit_mmap(). The munlocking happens a few lines below. The obvious thing to do would be to move arch_exit_mmap() to below the munlock code, but I think we'd want to call it even if mm->mmap is NULL, just to be on the safe side. Thus, this patch: exit_mmap() needs to unlock any locked vmas before calling arch_exit_mmap, as the latter may switch the current mm to init_mm, which would cause the former to fail.
