* [GFS2] Quotas non-functional - fix bugAbhijith Das2007-07-091-0/+8
| | | | | | | | | | This patch fixes an error in the quota code where a 'struct gfs2_quota_lvb*' was being passed to gfs2_adjust_quota() instead of a 'struct gfs2_quota_data*'. Also moved 'struct gfs2_quota_lvb' from fs/gfs2/incore.h to include/linux/gfs2_ondisk.h as per Steve's suggestion.

* [GFS2] Clean up inode number handlingSteven Whitehouse2007-07-091-9/+2
| | | | | | | | | | | | | | | | | | | | | | | This patch cleans up the inode number handling code. The main difference is that instead of looking up the inodes using a struct gfs2_inum_host we now use just the no_addr member of this structure. The tests relating to no_formal_ino can then be done by the calling code. This has advantages in that we want to do different things in different code paths if the no_formal_ino doesn't match. In the NFS patch we want to return -ESTALE, but in the ->lookup() path, its a bug in the fs if the no_formal_ino doesn't match and thus we can withdraw in this case. In order to later fix bz #201012, we need to be able to look up an inode without knowing no_formal_ino, as the only information that is known to us is the on-disk location of the inode in question. This patch will also help us to fix bz #236099 at a later date by cleaning up a lot of the code in that area. There are no user visible changes as a result of this patch and there are no changes to the on-disk format either. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* sis5513: adding PCI-IDUwe Koziolek2007-07-081-0/+1
| | | | | | | | | | | | | | | The SiS966 has one additional PCI-ID 1180. If the chipset is using this PCI-ID, the primary channel is connected to the first PATA-port. The secondary channel is connected to SATA-ports in IDE emulation mode. The legacy IO-ports are used. The including of the PCI-ID into pata_sis is not sufficient, because the legacy driver in drivers/ide is initialized before pata_sis.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many laptops have rf-kill physical switches that are not keys, but slider or rocker switches. Often (like in all ThinkPads with a radio kill slider switch), they have both a slider/rocker switch and a hot key. Trying to kludge a real switch to act like a key is not a very smart thing to do if you can help it, and it gets specially bad when you are going to have both in the same machine. So, we do the right thing and add an input EV_SW event for radio kill switches. The EV_SW SW_RADIO event is defined with positive logic, i.e. when the switch is active, the radios are to be enabled. When the switch is inactive, the radios are to be disabled. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* | PM: introduce set_target method in pm_opsRafael J. Wysocki2007-07-011-15/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code ordering to execute pm_ops->prepare() after the device model per-device .suspend() calls in order to fix some ACPI-related issues. Unfortunately, it broke the at91 platform which assumed that pm_ops->prepare() would be called before suspending devices. at91 used pm_ops->prepare() to get notified of the target system sleep state, so that it could use this information while suspending devices. However, with the current suspend code ordering pm_ops->prepare() is called too late for this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that will be used for notifying the platform of the target system sleep state. Moreover, in the future such a method will also be needed by ACPI. This patch adds the .set_target() method to 'struct pm_ops' and makes the suspend code call it, if implemented, before executing the device model per-device .suspend() calls. It also modifies the at91 code to use pm_ops->set_target() instead of pm_ops->prepare(). Signed-off-by: Rafael J.

* | Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARMDavid Woodhouse2007-06-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all the world is an i386. Many architectures need 64-bit arguments to be aligned in suitable pairs of registers, and the original sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an argument register for padding after the first integer. Since we don't normally have more than 6 arguments for system calls, that left no room for the final argument on some architectures. Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which all fits nicely. In fact, ARM already had that, but called it sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement the needed compatibility routine. And stop the missing syscall check from bitching about the absence of sys_sync_file_range() if we've implemented sys_sync_file_range2() instead. Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

It not only introduced user space visible changes to the futex syscall, it is also non-functional and there is no way to fix it proper before the 2.6.22 release. The breakage report ( http://lkml.org/lkml/2007/5/12/17 ) went unanswered, and unfortunately it turned out that the concept is not feasible at all. It violates the rtmutex semantics badly by introducing a virtual owner, which hacks around the coupling of the user-space pi_futex and the kernel internal rt_mutex representation. At the moment the only safe option is to remove it fully as it contains user-space visible changes to broken kernel code, which we do not want to expose in the 2.6.22 release. The patch reverts the original patch mostly 1:1, but contains a couple of trivial manual cleanups which were necessary due to patches, which touched the same area of code later. Verified against the glibc tests and my own PI futex tests.

To help these tools and to make it easier for people just browsing /proc/<pid>/maps this patch modifies hugetlb sysv shared memory to use the SYSV<key> dentry naming convention. User space tools will still have to be aware that hugetlb sysv shared memory lives on a different internal kernel mount and so has a different block device minor number from the rest of sysv shared memory.

Thus the size of the small slabs is all the same. No arch sets ARCH_KMALLOC_MINALIGN larger than 8 though except mips which for some reason wants a 128 byte alignment. This patch increases the size of the smallest cache if ARCH_KMALLOC_MINALIGN is greater than 8. In that case more and more of the smallest caches are disabled. If we do that then the count of the active general caches that is displayed on boot is not correct anymore since we may skip elements of the kmalloc array. So count them separately.

Inaccurate timestamps could be fed to them without providing any way for them to identify such cases. Previously RTT sampler was called only if FLAG_RETRANS_DATA_ACKED was not set filtering inaccurate timestamps nicely. In addition, the new behavior could give an invalid timestamp (zero) to RTT sampler if only skbs with TCPCB_RETRANS were ACKed. This solves both problems.

Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

* | | pi-futex: fix exit races and locking problemsAlexey Kuznetsov2007-06-081-0/+1

New entries can be added to tsk->pi_state_list after task completed exit_pi_state_list(). The result is memory leakage and deadlocks. 2. handle_mm_fault() is called under spinlock. The result is obvious. 3. results in self-inflicted deadlock inside glibc. Sometimes futex_lock_pi returns -ESRCH, when it is not expected and glibc enters to for(;;) sleep() to simulate deadlock. This problem is quite obvious and I think the patch is right. Though it looks like each "if" in futex_lock_pi() got some stupid special case "else if". :-) 4. sometimes futex_lock_pi() returns -EDEADLK, when nobody has the lock. The reason is also obvious (see comment in the patch), but correct fix is far beyond my comprehension. I guess someone already saw this, the chunk: if (rt_mutex_trylock(&q.pi_state->pi_mutex)) ret = 0; is obviously from the same opera. But it does not work, because the rtmutex is really taken at this point: wake_futex_pi() of previous owner reassigned it to us. My fix works. But it looks very stupid. I would think about removal of shift of ownership in wake_futex_pi() and making all the work in context of process taking lock. From: Thomas Gleixner <tglx@linutronix.de> Fix 1) Avoid the tasklist lock variant of the exit race fix by adding an additional state transition to the exit code. This fixes also the issue, when a task with recursive segfaults is not able to release the futexes. Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH problem finally. Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup in the lock protected section by using the in_atomic userspace access functions. This removes also the ugly lock drop / unqueue inside of fixup_pi_state() Fix 4) Fix a stale lock in the error path of futex_wake_pi() Added some error checks for verification. The -EDEADLK problem is solved by the rtmutex fixups.

* | | SLUB: return ZERO_SIZE_PTR for kmalloc(0)Christoph Lameter2007-06-081-8/+17
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of returning the smallest available object return ZERO_SIZE_PTR. A ZERO_SIZE_PTR can be legitimately used as an object pointer as long as it is not deferenced. The dereference of ZERO_SIZE_PTR causes a distinctive fault. kfree can handle a ZERO_SIZE_PTR in the same way as NULL. This enables functions to use zero sized object. e.g. n = number of objects. objects = kmalloc(n * sizeof(object)); for (i = 0; i < n; i++) objects[i].x = y; kfree(objects); Signed-off-by: Christoph Lameter <clameter@sgi.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | [NETFILTER]: ip_tables: fix compat related crashDmitry Mishin2007-06-071-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check_compat_entry_size_and_hooks iterates over the matches and calls compat_check_calc_match, which loads the match and calculates the compat offsets, but unlike the non-compat version, doesn't call ->checkentry yet. On error however it calls cleanup_matches, which in turn calls ->destroy, which can result in crashes if the destroy function (validly) expects to only get called after the checkentry function. Add a compat_release_match function that only drops the module reference on error and rename compat_check_calc_match to compat_find_calc_match to reflect the fact that it doesn't call the checkentry function.

* | [IPV4]: Restore old behaviour of default config valuesHerbert Xu2007-06-071-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously inet devices were only constructed when addresses are added (or rarely in ipmr). Therefore the default config values they get are the ones at the time of these operations. Now that we're creating inet devices earlier, this changes the behaviour of default config values in an incompatible way (see bug #8519). This patch creates a compromise by setting the default values at the same point as before but only for those that have not been explicitly set by the user since the inet device's creation.

* | [IPV4]: Add default config support after inetdev_initHerbert Xu2007-06-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously once inetdev_init has been called on a device any changes made to ipv4_devconf_dflt would have no effect on that device's configuration. This creates a problem since we have moved the point where inetdev_init is called from when an address is added to where the device is registered. This patch is the first half of a set that tries to mimic the old behaviour while still calling inetdev_init. It propagates any changes to ipv4_devconf_dflt to those devices that have not had the corresponding attribute set. The next patch will forcibly set all values at the point where inetdev_init was previously called. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
