2007-06-08hexdump: more output formattingRandy Dunlap
Add a prefix string parameter. 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.

2007-06-08pi-futex: fix exit races and locking problemsAlexey Kuznetsov
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.

2007-06-08SLUB: return ZERO_SIZE_PTR for kmalloc(0)Christoph Lameter
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>

2007-06-07xfrm: Add security check before flushing SAD/SPDJoy Latten
Currently we check for permission before deleting entries from SAD and SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete()) However we are not checking for authorization when flushing the SPD and the SAD completely. It was perhaps missed in the original security hooks patch. This patch adds a security check when flushing entries from the SAD and SPD. It runs the entire database and checks each entry for a denial. If the process attempting the flush is unable to remove all of the entries a denial is logged the the flush function returns an error without removing anything. This is particularly useful when a process may need to create or delete its own xfrm entries used for things like labeled networking but that same process should not be able to delete other entries or flush the entire database.

2007-06-07[NETFILTER]: ip_tables: fix compat related crashDmitry Mishin
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.

2007-06-07[IPV4]: Restore old behaviour of default config valuesHerbert Xu
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.

2007-06-07[IPV4]: Add default config support after inetdev_initHerbert Xu
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.

2007-06-04libata: always use polling SETXFERTejun Heo
Several people have reported LITE-ON LTR-48246S detection failed because SETXFER fails. It seems the device raises IRQ too early after SETXFER. This is controller independent. The same problem has been reported for different controllers. So, now we have pata_via where the controller raises IRQ before it's ready after SETXFER and a device which does similar thing. This patch makes libata always execute SETXFER via polling. As this only happens during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is also moved from issue hot path to ata_dev_set_xfermode() - the only place where SETXFER can be issued. Note that ATA_TFLAG_POLLING applies only to drivers which implement SFF TF interface and use libata HSM. More advanced controllers ignore the flag. This doesn't matter for this fix as SFF TF controllers are the problematic ones. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

I think we have a subtle race on ppc64 with the tlb batching. The common code expects tlb_flush() to actually flush any pending TLB batch. It does that because it delays all page freeing until after tlb_flush() is called, in order to ensure no stale reference to those pages exist in any TLB, thus causing potential access to the freed pages. However, our tlb_flush only triggers the RCU for freeing page table pages, it does not currently trigger a flush of a pending TLB/hash batch, which is, I think, an error. This fixes it.

2007-06-01ALPHA: support graphics on non-zero PCI domainsJay Estabrook
This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.

2007-06-01fbdev: Move declaration of fb_class to <linux/fb.h>Geert Uytterhoeven
Move the forward declaration of fb_class from drivers/video/console/fbcon.h to <linux/fb.h>, together with the other forward declarations related to drivers/video/fbmem.c. This kills the following sparse warning: | drivers/video/fbmem.c:1363:14: warning: symbol 'fb_class' was not declared. Should it be static?

2007-06-01x86_64: allocate sparsemem memmap above 4GZou Nan hai
On systems with huge amount of physical memory, VFS cache and memory memmap may eat all available system memory under 4G, then the system may fail to allocate swiotlb bounce buffer. There was a fix for this issue in arch/x86_64/mm/numa.c, but that fix dose not cover sparsemem model. This patch add fix to sparsemem model by first try to allocate memmap above 4G.

2007-05-31Xtensa: use asm-generic/fcntl.hStephen Rothwell
Commit fc4fb2adf944d45a7f3d4d38df991c79ffdb6a43 "fixed" the Xtensa asm/fcntl.h and in doing so ignored asm-generic/fcntl.h completely. It turns out that it is now exactly the same as asm-generic/fcntl.h.
