* [PATCH] Chardev checking of overlapping rangesAmos Waterland2006-09-29
| | | | | | | | | | | | | | | The code in __register_chrdev_region checks that if the driver wishing to register has the same major as an existing driver the new minor range is strictly less than the existing minor range. However, it does not also check that the new minor range is strictly greater than the existing minor range. That is, if driver X has registered with major=x and minor=0-3, __register_chrdev_region will allow driver Y to register with major=x and minor=1-4.

* [PATCH] pidspace: is_init()Sukadev Bhattiprolu2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an updated version of Eric Biederman's is_init() patch. (http://lkml.org/lkml/2006/2/6/280). It applies cleanly to 2.6.18-rc3 and replaces a few more instances of ->pid == 1 with is_init(). Further, is_init() checks pid and thus removes dependency on Eric's other patches for now. Eric's original description: There are a lot of places in the kernel where we test for init because we give it special properties. Most significantly init must not die. This results in code all over the kernel test ->pid == 1. Introduce is_init to capture this case. With multiple pid spaces for all of the cases affected we are looking for only the first process on the system, not some other process that has pid == 1. Signed-off-by: Eric W.

* [PATCH] Fix conflict with the is_init identifier on pariscEric Biederman2006-09-29
| | | | | | | | | | | | | | | | | | This appears to be the only usage of is_init in the kernel besides the usage in sched.h. On ia64 the same function is called in_init. So to remove the conflict and make the kernel more consistent rename is_init is_core is_local and is_local_section to in_init in_core in_local and in_local_section respectively. Thanks to Adrian Bunk who spotted this, and to Matthew Wilcox who suggested this fix.

* [PATCH] tty locking on resizeAlan Cox2006-09-29
| | | | | | | | | | | | | | | | | | | The current kernel serializes console resizes but does not serialize the resize against the tty structure updates. This means that while two parallel resizes cannot mess up the console you can get incorrect results reported. Secondly while doing this I added vc_lock_resize() to lock and resize the console. This leaves all knowledge of the console_sem in the vt/console driver and kicks it out of the tty layer, which is good Thirdly while doing this I decided I couldn't stand "disallocate" any longer so I switched it to "deallocate".

* [PATCH] fs.h: ifdef security fieldsAlexey Dobriyan2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [assuming BSD security levels are deleted] The only user of i_security, f_security, s_security fields is SELinux, however, quite a few security modules are trying to get into kernel. So, wrap them under CONFIG_SECURITY. Adding config option for each security field is likely an overkill. Following Stephen Smalley's suggestion, i_security initialization is moved to security_inode_alloc() to not clutter core code with ifdefs and make alloc_inode() codepath tiny little bit smaller and faster. The user of (highly greppable) struct fown_struct::security field is still to be found. I've checked every "fown_struct" and every "f_owner" occurence. Additionally it's removal doesn't break i386 allmodconfig build. struct inode, struct file, struct super_block, struct fown_struct become smaller. P.S. Combined with two reiserfs inode shrinking patches sent to linux-fsdevel, I can finally suck 12 reiserfs inodes into one page. /proc/slabinfo -ext2_inode_cache 388 10 +ext2_inode_cache 384 10 -inode_cache 280 14 +inode_cache 276 14 -proc_inode_cache 296 13 +proc_inode_cache 292 13 -reiser_inode_cache 336 11 +reiser_inode_cache 332 12 <= -shmem_inode_cache 372 10 +shmem_inode_cache 368 10 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Cc: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Fix reiserfs latencies caused by data=orderedChris Mason2006-09-29
| | | | | | | | | | | | | | | | | ReiserFS does periodic cleanup of old transactions in order to limit the length of time a journal replay may take after a crash. Sometimes, writing metadata from an old (already committed) transaction may require committing a newer transaction, which also requires writing all data=ordered buffers. This can cause very long stalls on journal_begin. This patch makes sure new transactions will not need to be committed before trying a periodic reclaim of an old transaction. It is low risk because if a bad decision is made, it just means a slightly longer journal replay after a crash.

* [PATCH] clean up and remove some extra spinlocks from rtmutexSteven Rostedt2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Oleg brought up some interesting points about grabbing the pi_lock for some protections. In this discussion, I realized that there are some places that the pi_lock is being grabbed when it really wasn't necessary. Also this patch does a little bit of clean up. This patch basically does three things: 1) renames the "boost" variable to "chain_walk". Since it is used in the debugging case when it isn't going to be boosted. It better describes what the test is going to do if it succeeds. 2) moves get_task_struct to just before the unlocking of the wait_lock. This removes duplicate code, and makes it a little easier to read. The owner wont go away while either the pi_lock or the wait_lock are held. 3) removes the pi_locking and owner blocked checking completely from the debugging case. This is because the grabbing the lock and doing the check, then releasing the lock is just so full of races. It's just as good to go ahead and call the pi_chain_walk function, since after releasing the lock the owner can then block anyway, and we would have missed that. For the debug case, we really do want to do the chain walk to test for deadlocks anyway.

* [PATCH] fix Intel RNG detectionJan Beulich2006-09-29
| | | | | | | | | | | | | | | | | | | Previously, since determination whether there was an Intel random number generator was based on a single bit, on systems with a matching bridge device but without a firmware hub, there was a 50% chance that the code would incorrectly decide that the system had an RNG. This patch adds detection of the firmware hub to better qualify the existence of an RNG. There is one issue with the patch: I was unable to determine the LPC equivalent for the PCI bridge 8086:2430 (since the old code didn't care about which of the many devices provided by the ICH/ESB it was chose to use the PCI bridge device, but the FWH settings live in the LPC device, so the device list needed to be changed).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug where a UDF_PART_FLAG_READ_ONLY udf partition gets mounted read-write, then subsequent problems happen; files seem to be able to be removed, but file creation results in EIO or worse, oops.

* [PATCH] ignore partition table on disks with AIX labelOlaf Hering2006-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The on-disk data structures from AIX are not known, also the filesystem layout is not known. There is a msdos partition signature at the end of the first block, and the kernel recognizes 3 small (and overlapping) partitions. But they are not usable. Maybe the firmware uses it to find the bootloader for AIX, but AIX boots also if the first block is cleared. This is the content of the partition table: # dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) | xxd 0000000: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0000010: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8... 0000020: 00ff ffff 41ff ffff 0211 0000 1900 0000 ....A........... 0000030: 80ff ffff 41ff ffff 1b11 0000 381b 0000 ....A.......8... Handle the whole disk as empty disk. This fixes also YaST which compares the output from parted (and formerly fdisk) with /proc/partitions. fdisk recognizes the AIX label since a long time, SuSE has a patch for parted to handle the disk label as unknown. dmesg will look like this: sda: [AIX] unknown partition table Tested on an IBM B50 with AIX V4.3.3.

Add a lock annotation to this function so that sparse can check callers for lock pairing, and so that sparse will not complain about this function since it intentionally uses the lock in this manner.

* [PATCH] vfs: define new lookup flag for chdirMiklos Szeredi2006-09-29
| | | | | | | | | | | | | In the "operation does permission checking" model used by fuse, chdir permission is not checked, since there's no chdir method. For this case set a lookup flag, which will be passed to ->permission(), so fuse can distinguish it from permission checks for other operations.

* [PATCH] fuse: use dentry in statfsMiklos Szeredi2006-09-29
| | | | | | | | | | | | | | | | Some filesystems may want to report different values depending on the path within the filesystem, i.e. one mount is actually several filesystems. This can be the case for a network filesystem exported by an unprivileged server (e.g. sshfs). This is now possible, thanks to David Howells "VFS: Permit filesystem to perform statfs with a known root dentry" patch. This change is backward compatible, so no need to change interface version.

* [PATCH] module_subsys: initialize earlierMark Huang2006-09-29
| | | | | | | | | | | | | | | | | | | Initialize module_subsys earlier (or at least earlier than devices) since it could be used very early in the boot process if kmod loads a module before the device initcalls. Otherwise, kmod will crash in kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not initialized yet. I only noticed this problem because occasionally, kmod loads the modules for my SCSI and Ethernet adapters very early, during the boot process itself. I don't quite understand why it loads them sometimes and doesn't load them other times. Or who is telling kmod to do so. Can someone explain?

* [PATCH] Require mmap handler for a.out executablesEugene Teo2006-09-29
| | | | | | | | | | | | | Files supported by fs/proc/base.c, i.e. /proc/<pid>/*, are not capable of meeting the validity checks in ELF load_elf_*() handling because they have no mmap handler which is required by ELF. In order to stop a.out executables being used as part of an exploit attack against /proc-related vulnerabilities, we make a.out executables depend on ->mmap() existing.
