2010-11-17BKL: remove extraneous #include <smp_lock.h>Arnd Bergmann137-137/+0
The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-11-17staging/stradis: mark as "depends on BKL"Arnd Bergmann1-1/+1
The stradis driver is on its way out, but it should still be marked correctly as depending on the big kernel lock. It could easily be changed to not require it if someone decides to revive the driver and port it to v4l2 in the process.

2010-11-16kernel: make /proc/kallsyms mode 400 to reduce ease of attackingMarcus Meissner1-1/+1
Making /proc/kallsyms readable only for root by default makes it slightly harder for attackers to write generic kernel exploits by removing one source of knowledge where things are in the kernel. This is the second submit, discussion happened on this on first submit and mostly concerned that this is just one hole of the sieve ... but one of the bigger ones. Changing the permissions of at least System.map and vmlinux is also required to fix the same set, but a packaging issue. Target of this starter patch and follow ups is removing any kind of kernel space address information leak from the kernel. [ Side note: the default of root-only reading is the "safe" value, and it's easy enough to then override at any time after boot. The /proc filesystem allows root to change the permissions with a regular chmod, so you can "revert" this at run-time by simply doing chmod og+r /proc/kallsyms as root if you really want regular users to see the kernel symbols. It does help some tools like "perf" figure them out without any setup, so it may well make sense in some situations. - Linus ] Signed-off-by: Marcus Meissner <meissner@suse.de> Acked-by: Tejun Heo <tj@kernel.org> Acked-by: Eugene Teo <eugeneteo@kernel.org> Reviewed-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-11-16SCSI host lock push-downJeff Garzik115-199/+347
Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

2010-11-16PCI: fix offset check for sysfs mmapped filesDarrick J. Wong1-1/+1
I just loaded 2.6.37-rc2 on my machines, and I noticed that X no longer starts. Running an strace of the X server shows that it's doing this: open("/sys/bus/pci/devices/0000:07:00.0/resource0", O_RDWR) = 10 mmap(NULL, 16777216, PROT_READ|PROT_WRITE, MAP_SHARED, 10, 0) = -1 EINVAL (Invalid argument) This code seems to be asking for a shared read/write mapping of 16MB worth of BAR0 starting at file offset 0, and letting the kernel assign a starting address. Unfortunately, this -EINVAL causes X not to start. Looking into dmesg, there's a complaint like so: process "Xorg" tried to map 0x01000000 bytes at page 0x00000000 on 0000:07:00.0 BAR 0 (start 0x 96000000, size 0x 1000000) ...with the following code in pci_mmap_fits: pci_start = (mmap_api == PCI_MMAP_SYSFS) ? pci_resource_start(pdev, resno) >> PAGE_SHIFT : 0; if (start >= pci_start && start < pci_start + size && start + nr <= pci_start + size) It looks like the logic here is set up such that when the mmap call comes via sysfs, the check in pci_mmap_fits wants vma->vm_pgoff to be between the resource's start and end address, and the end of the vma to be no farther than the end. However, the sysfs PCI resource files always start at offset zero, which means that this test always fails for programs that mmap the sysfs files. Given the comment in the original commit 3b519e4ea618b6943a82931630872907f9ac2c2b, I _think_ the old procfs files require that the file offset be equal to the resource's base address when mmapping. I think what we want here is for pci_start to be 0 when mmap_api == PCI_MMAP_PROCFS. The following patch makes that change, after which the Matrox and Mach64 X drivers work again.

2010-11-15capabilities/syslog: open code cap_syslog logic to fix build failureEric Paris7-40/+28
The addition of CONFIG_SECURITY_DMESG_RESTRICT resulted in a build failure when CONFIG_PRINTK=n. This is because the capabilities code which used the new option was built even though the variable in question didn't exist. The patch here fixes this by moving the capabilities checks out of the LSM and into the caller. All (known) LSMs should have been calling the capabilities hook already so it actually makes the code organization better to eliminate the hook altogether.

2010-11-15Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)Jim Bos1-4/+4
The fix in commit 6b4e81db2552 ("i8k: Tell gcc that *regs gets clobbered") to work around the gcc miscompiling i8k.c to add "+m (*regs)" caused register pressure problems and a build failure. Changing the 'asm' statement to 'asm volatile' instead should prevent that and works around the gcc bug as well, so we can remove the "+m". [ Background on the gcc bug: a memory clobber fails to mark the function the asm resides in as non-pure (aka "__attribute__((const))"), so if the function does nothing else that triggers the non-pure logic, gcc will think that that function has no side effects at all. As a result, callers will be mis-compiled. Adding the "+m" made gcc see that it's not a pure function, and so does "asm volatile". The problem was never really the need to mark "*regs" as changed, since the memory clobber did that part - the problem was just a bug in the gcc "pure" function analysis - Linus ] Signed-off-by: Jim Bos <jim876@xs4all.nl> Acked-by: Jakub Jelinek <jakub@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Andreas Schwab <schwab@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-11-15GFS2: Fix inode deallocation raceSteven Whitehouse5-216/+98
This area of the code has always been a bit delicate due to the subtleties of lock ordering. The problem is that for "normal" alloc/dealloc, we always grab the inode locks first and the rgrp lock later. In order to ensure no races in looking up the unlinked, but still allocated inodes, we need to hold the rgrp lock when we do the lookup, which means that we can't take the inode glock. The solution is to borrow the technique already used by NFS to solve what is essentially the same problem (given an inode number, look up the inode carefully, checking that it really is in the expected state). We cannot do that directly from the allocation code (lock ordering again) so we give the job to the pre-existing delete workqueue and carry on with the allocation as normal. If we find there is no space, we do a journal flush (required anyway if space from a deallocation is to be released) which should block against the pending deallocations, so we should always get the space back.
