* [PATCH] CHECK_IRQ_PER_CPU() to avoid dead code in __do_IRQ()Karsten Wiese2005-09-07
| | | | | | | | | | | | | | | | | | | IRQ_PER_CPU is not used by all architectures. This patch introduces the macros ARCH_HAS_IRQ_PER_CPU and CHECK_IRQ_PER_CPU() to avoid the generation of dead code in __do_IRQ(). ARCH_HAS_IRQ_PER_CPU is defined by architectures using IRQ_PER_CPU in their include/asm_ARCH/irq.h file. Through grepping the tree I found the following architectures currently use IRQ_PER_CPU: cris, ia64, ppc, ppc64 and parisc.

* [PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | When registering an RPC cache, cache_register() always sets the owner as the sunrpc module. However, there are RPC caches owned by other modules. With the incorrect owner setting, the real owning module can be removed potentially with an open reference to the cache from userspace. For example, if one were to stop the nfs server and unmount the nfsd filesystem, the nfsd module could be removed eventhough rpc.idmapd had references to the idtoname and nametoid caches (i.e. /proc/net/rpc/nfs4.<cachename>/channel is still open). This resulted in a system panic on one of our machines when attempting to restart the nfs services after reloading the nfsd module. The following patch adds a 'struct module *owner' field in struct cache_detail. The owner is further assigned to the struct proc_dir_entry in cache_register() so that the module cannot be unloaded while user-space daemons have an open reference on the associated file under /proc.

| | | | | | | | | | | | Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to initialize the SPIC device.

* [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mountsMark Bellon2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If /etc/mtab is a regular file all of the mount options (of a file system) are written to /etc/mtab by the mount command. The quota tools look there for the quota strings for their operation. If, however, /etc/mtab is a symlink to /proc/mounts (a "good thing" in some environments) the tools don't write anything - they assume the kernel will take care of things. While the quota options are sent down to the kernel via the mount system call and the file system codes handle them properly unfortunately there is no code to echo the quota strings into /proc/mounts and the quota tools fail in the symlink case. The attached patchs modify the EXT[2|3] and JFS codes to add the necessary hooks. The show_options function of each file system in these patches currently deal with only those things that seemed related to quotas; especially in the EXT3 case more can be done (later?). Jan Kara also noted the difficulty in moving these changes above the FS codes responding similarly to myself to Andrew's comment about possible VFS migration. Issue summary: - FS codes have to process the entire string of options anyway. - Only FS codes that use quotas must have a show_options function (for quotas to work properly) however quotas are only used in a small number of FS. - Since most of the quota using FS support other options these FS codes should have the a show_options function to show those options - and the quota echoing becomes virtually negligible. Based on feedback I have modified my patches from the original: JFS a missing patch has been restored to the posting EXT[2|3] and JFS always use the show_options function - Each FS has at least one FS specific option displayed - QUOTA output is under a CONFIG_QUOTA ifdef - a follow-on patch will add a multitude of options for each FS EXT[2|3] and JFS "quota" is treated as "usrquota" EXT3 journalled data check for journalled quota removed EXT[2|3] mount when quota specified but not compiled in - no changes from my original patch. I tested the patch and the codes warn but - still mount. With all due respection I believe the comments otherwise were a - misread of the patch. Please reread/test and comment. XFS patch removed - the XFS team already made the necessary changes EXT3 mixing old and new quotas are handled differently (not purely exclusive) - if old and new quotas for the same type are used together the old type is silently depricated for compatability (e.g. usrquota and usrjquota) - mixing of old and new quotas is an error (e.g. usrjquota and grpquota) Signed-off-by: Mark Bellon <mbellon@mvista.com> Acked-by: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Jan Kara <jack@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] auxiliary vector cleanupsH. J. Lu2005-09-07
| | | | | | | | | | | | The size of auxiliary vector is fixed at 42 in linux/sched.h. But it isn't very obvious when looking at linux/elf.h. This patch adds AT_VECTOR_SIZE so that we can change it if necessary when a new vector is added.

* [PATCH] compat: be more consistent about [ug]id_tStephen Rothwell2005-09-07
| | | | | | | | | | | | | | | | | | | | When I first wrote the compat layer patches, I was somewhat cavalier about the definition of compat_uid_t and compat_gid_t (or maybe I just misunderstood :-)). This patch makes the compat types much more consistent with the types we are being compatible with and hopefully will fix a few bugs along the way. compat type type in compat arch __compat_[ug]id_t __kernel_[ug]id_t __compat_[ug]id32_t __kernel_[ug]id32_t compat_[ug]id_t [ug]id_t The difference is that compat_uid_t is always 32 bits (for the archs we care about) but __compat_uid_t may be 16 bits on some.

* [PATCH] relayfsTom Zanussi2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's the latest version of relayfs, against linux-2.6.11-mm2. I'm hoping you'll consider putting this version back into your tree - the previous rounds of comment seem to have shaken out all the API issues and the number of comments on the code itself have also steadily dwindled. This patch is essentially the same as the relayfs redux part 5 patch, with some minor changes based on reviewer comments. Thanks again to Pekka Enberg for those. The patch size without documentation is now a little smaller at just over 40k. Here's a detailed list of the changes: - removed the attribute_flags in relay open and changed it to a boolean specifying either overwrite or no-overwrite mode, and removed everything referencing the attribute flags. - added a check for NULL names in relayfs_create_entry() - got rid of the unnecessary multiple labels in relay_create_buf() - some minor simplification of relay_alloc_buf() which got rid of a couple params - updated the Documentation In addition, this version (through code contained in the relay-apps tarball linked to below, not as part of the relayfs patch) tries to make it as easy as possible to create the cooperating kernel/user pieces of a typical and common type of logging application, one where kernel logging is kicked off when a user space data collection app starts and stops when the collection app exits, with the data being automatically logged to disk in between. To create this type of application, you basically just include a header file (relay-app.h, included in the relay-apps tarball) in your kernel module, define a couple of callbacks and call an initialization function, and on the user side call a single function that sets up and continuously monitors the buffers, and writes data to files as it becomes available. Channels are created when the collection app is started and destroyed when it exits, not when the kernel module is inserted, so different channel buffer sizes can be specified for each separate run via command-line options. See the README in the relay-apps tarball for details. Also included in the relay-apps tarball are a couple examples demonstrating how you can use this to create quick and dirty kernel logging/debugging applications. They are: - tprintk, short for 'tee printk', which temporarily puts a kprobe on printk() and writes a duplicate stream of printk output to a relayfs channel. This could be used anywhere there's printk() debugging code in the kernel which you'd like to exercise, but would rather not have your system logs cluttered with debugging junk. You'd probably want to kill klogd while you do this, otherwise there wouldn't be much point (since putting a kprobe on printk() doesn't change the output of printk()). I've used this method to temporarily divert the packet logging output of the iptables LOG target from the system logs to relayfs files instead, for instance. - klog, which just provides a printk-like formatted logging function on top of relayfs. Again, you can use this to keep stuff out of your system logs if used in place of printk.

* [PATCH] detect soft lockupsIngo Molnar2005-09-07
| | | | | | | | | | | | | | | | | | | This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP. When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump (once per lockup incident). The feature is otherwise non-intrusive, it doesnt try to unlock the box in any way, it only gets the debug info out, automatically, and on all CPUs affected by the lockup.

* [PATCH] FUTEX_WAKE_OP: pthread_cond_signal() speedupJakub Jelinek2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ATM pthread_cond_signal is unnecessarily slow, because it wakes one waiter (which at least on UP usually means an immediate context switch to one of the waiter threads). This waiter wakes up and after a few instructions it attempts to acquire the cv internal lock, but that lock is still held by the thread calling pthread_cond_signal. So it goes to sleep and eventually the signalling thread is scheduled in, unlocks the internal lock and wakes the waiter again. Now, before 2003-09-21 NPTL was using FUTEX_REQUEUE in pthread_cond_signal to avoid this performance issue, but it was removed when locks were redesigned to the 3 state scheme (unlocked, locked uncontended, locked contended). Following scenario shows why simply using FUTEX_REQUEUE in pthread_cond_signal together with using lll_mutex_unlock_force in place of lll_mutex_unlock is not enough and probably why it has been disabled at that time: The number is value in cv->__data.__lock. thr1 thr2 thr3 0 pthread_cond_wait 1 lll_mutex_lock (cv->__data.__lock) 0 lll_mutex_unlock (cv->__data.__lock) 0 lll_futex_wait (&cv->__data.__futex, futexval) 0 pthread_cond_signal 1 lll_mutex_lock (cv->__data.__lock) 1 pthread_cond_signal 2 lll_mutex_lock (cv->__data.__lock) 2 lll_futex_wait (&cv->__data.__lock, 2) 2 lll_futex_requeue (&cv->__data.__futex, 0, 1, &cv->__data.__lock) # FUTEX_REQUEUE, not FUTEX_CMP_REQUEUE 2 lll_mutex_unlock_force (cv->__data.__lock) 0 cv->__data.__lock = 0 0 lll_futex_wake (&cv->__data.__lock, 1) 1 lll_mutex_lock (cv->__data.__lock) 0 lll_mutex_unlock (cv->__data.__lock) # Here, lll_mutex_unlock doesn't know there are threads waiting # on the internal cv's lock Now, I believe it is possible to use FUTEX_REQUEUE in pthread_cond_signal, but it will cost us not one, but 2 extra syscalls and, what's worse, one of these extra syscalls will be done for every single waiting loop in pthread_cond_*wait. We would need to use lll_mutex_unlock_force in pthread_cond_signal after requeue and lll_mutex_cond_lock in pthread_cond_*wait after lll_futex_wait. Another alternative is to do the unlocking pthread_cond_signal needs to do (the lock can't be unlocked before lll_futex_wake, as that is racy) in the kernel. I have implemented both variants, futex-requeue-glibc.patch is the first one and futex-wake_op{,-glibc}.patch is the unlocking inside of the kernel. The kernel interface allows userland to specify how exactly an unlocking operation should look like (some atomic arithmetic operation with optional constant argument and comparison of the previous futex value with another constant). It has been implemented just for ppc*, x86_64 and i?86, for other architectures I'm including just a stub header which can be used as a starting point by maintainers to write support for their arches and ATM will just return -ENOSYS for FUTEX_WAKE_OP. The requeue patch has been (lightly) tested just on x86_64, the wake_op patch on ppc64 kernel running 32-bit and 64-bit NPTL and x86_64 kernel running 32-bit and 64-bit NPTL. With the following benchmark on UP x86-64 I get: for i in nptl-orig nptl-requeue nptl-wake_op; do echo time elf/ld.so --library-path .:$i /tmp/bench; \ for j in 1 2; do echo ( time elf/ld.so --library-path .:$i /tmp/bench ) 2>&1; done; done time elf/ld.so --library-path .:nptl-orig /tmp/bench real 0m0.655s user 0m0.253s sys 0m0.403s real 0m0.657s user 0m0.269s sys 0m0.388s time elf/ld.so --library-path .:nptl-requeue /tmp/bench real 0m0.496s user 0m0.225s sys 0m0.271s real 0m0.531s user 0m0.242s sys 0m0.288s time elf/ld.so --library-path .:nptl-wake_op /tmp/bench real 0m0.380s user 0m0.176s sys 0m0.204s real 0m0.382s user 0m0.175s sys 0m0.207s The benchmark is at: http://sourceware.org/ml/libc-alpha/2005-03/txt00001.txt Older futex-requeue-glibc.patch version is at: http://sourceware.org/ml/libc-alpha/2005-03/txt00002.txt Older futex-wake_op-glibc.patch version is at: http://sourceware.org/ml/libc-alpha/2005-03/txt00003.txt Will post a new version (just x86-64 fixes so that the patch applies against pthread_cond_signal.S) to libc-hacker ml soon. Attached is the kernel FUTEX_WAKE_OP patch as well as a simple-minded testcase that will not test the atomicity of the operation, but at least check if the threads that should have been woken up are woken up and whether the arithmetic operation in the kernel gave the expected results.

* [PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinityAshok Raj2005-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling writes to /proc/irq, current code is re-programming rte entries directly. This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well. MSI testing: tbd: I have cards, need to look for a x-over cable, although I did test an earlier version of this patch. Will test in a couple days.

Eg in atomic_dec_and_test we get: stw r10,112(r1) stw r9,116(r1) lwz r9,112(r1) lwz r0,116(r1) x86 is just casting the values so do that instead. Also change __xchg* and __cmpxchg* to take unsigned values, removing a few sign extensions. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hardware Patch from Richard Purdie This patch updates the PCMCIA pxa2xx_sharpsl driver to support multiple scoop devices by adding a scoop to pcmcia slot mapping structure. It adds platform support for poodle, is known to work on spitz (which is dual slot) and should also support collie with a minor amount of further work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several reports on inconsistent kallsyms data has been caused by the aliased symbols __sched_text_start and __down to shift places in the output of nm. The root cause was that on second pass ld aligned __sched_text_start to a 4 byte boundary which is the function alignment on i386. sched.text and spinlock.text is now aligned to an 8 byte boundary to make sure they are aligned to a function alignemnt on most (all?) archs.

The cause of the incompatibility has gone since [2], so I think we can get rid of them, as they tend to make the code harder to read and longer to preprocess/compile for no more benefit. I'd hope nobody seriously attempts to keep media/video driver compatible across Linux trees anymore, BTW.

However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.
