2007-09-14Fix kernel buuild with (CONFIG_COMPAT && ! CONFIG_BLOCK)aherrman@arcor.de
Commit 02a5e0acb3cb85d80d0fe834e366d38a92bbaa22 ("BLOCK: Hide the contents of linux/bio.h if CONFIG_BLOCK=n") broke the kernel build for the CONFIG_COMPAT && !CONFIG_BLOCK case: CC fs/compat_ioctl.o In file included from include/linux/raid/md_k.h:19, from include/linux/raid/md.h:54, from fs/compat_ioctl.c:25: include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:40: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:48: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h:51: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:64: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_merge_: include/linux/raid/../../../drivers/md/dm-bio-list.h:78: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:90: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h:94: error: dereferencing pointer to incomplete type make[1]: *** [fs/compat_ioctl.o] Error 1 make: *** [fs] Error 2 Signed-off-by: Andreas Herrmann <aherrman@arcor.de> Acked-By: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-09-14shared tag queue barrier commentNick Piggin
Should add some comments for the tag barriers (they won't be so important if we can switch over to the explicit _lock bitops, but for now we should make it clear). Jens' original patch said a barrier after the test_and_clear_bit was also required. I can't see why (and it would prevent the use of the _lock bitop).

2007-09-13Fix race with shared tag queue mapsJens Axboe
There's a race condition in blk_queue_end_tag() for shared tag maps, users include stex (promise supertrak thingy) and qla2xxx. The former at least has reported bugs in this area, not sure why we haven't seen any for the latter. It could be because the window is narrow and that other conditions in the qla2xxx code hide this. It's a real bug, though, as the stex smp users can attest. We need to ensure two things - the tag bit clearing needs to happen AFTER we cleared the tag pointer, as the tag bit clearing/setting is what protects this map. Secondly, we need to ensure that the visibility of the tag pointer and tag bit clear are ordered properly.

With the I/O space rewrite by BenH, the legacy_serial serial_dev_init() initcall is now called before I/O space is setup, but it's dependent on it being available. Since there's no way to make dependencies between initcalls, we'll just have to move it to device_initcall().

2007-09-12Define termios_1 functions for powerpc, s390, avr32 and frvPaul Mackerras
Commit f629307c857c030d5a3dd777fee37c8bb395e171 introduced uses of kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1 on all architectures. However, powerpc, s390, avr32 and frv don't currently define those functions since their termios struct didn't need to be changed when the arbitrary baud rate stuff was added, and thus the kernel won't currently build on those architectures. This adds definitions of kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1 to include/asm-generic/termios.h which are identical to kernel_termios_to_user_termios and user_termios_to_kernel_termios respectively. The definitions are the same because the "old" termios and "new" termios are in fact the same on these architectures (which are the same ones that use asm-generic/termios.h).

Intel framebuffer mis-calculated pixel clocks. The pixel clock (and thus both H and V sync) will be slower than requested, so if you set the minimum allowed the display may not sync. In case of really old CRT display it could theoretically damage it.

2007-09-11SLUB: accurately compare debug flags during slab cache mergeChristoph Lameter
This was posted on Aug 28 and fixes an issue that could cause troubles when slab caches >=128k are created. http://marc.info/?l=linux-mm&m=118798149918424&w=2 Currently we simply add the debug flags unconditional when checking for a matching slab. This creates issues for sysfs processing when slabs exist that are exempt from debugging due to their huge size or because only a subset of slabs was selected for debugging. We need to only add the flags if kmem_cache_open() would also add them. Create a function to calculate the flags that would be set if the cache would be opened and use that function to determine the flags before looking for a compatible slab.

2007-09-11revert "highmem: catch illegal nesting"Andrew Morton
Revert commit 656dad312fb41ed95ef08325e9df9bece3aacbbb Author: Ingo Molnar <mingo@elte.hu> Date: Sat Feb 10 01:46:36 2007 -0800 [PATCH] highmem: catch illegal nesting Catch illegally nested kmap_atomic()s even if the page that is mapped by the 'inner' instance is from lowmem. This avoids spuriously zapped kmap-atomic ptes and turns hard to find crashes into clear asserts at the bug site. Problem is, a get_zeroed_page(GFP_KERNEL) from interrupt context will trigger this check if non-irq code on this CPU holds a KM_USER0 mapping. But that get_zeroed_page() will never be altering the kmap slot anyway due to the GFP_KERNEL.

2007-09-11Leases can be hidden by flocksPavel Emelyanov
The inode->i_flock list contains the leases, flocks and posix locks in the specified order. However, the flocks are added in the head of this list thus hiding the leases from F_GETLEASE command, from time_out_leases() and other code that expects the leases to come first. The following example will demonstrate this: #define _GNU_SOURCE #include <unistd.h> #include <fcntl.h> #include <stdio.h> #include <sys/file.h> static void show_lease(int fd) { int res; res = fcntl(fd, F_GETLEASE); switch (res) { case F_RDLCK: printf("Read lease\n"); break; case F_WRLCK: printf("Write lease\n"); break; case F_UNLCK: printf("No leases\n"); break; default: printf("Some shit\n"); break; } } int main(int argc, char **argv) { int fd, res; fd = open(argv[1], O_RDONLY); if (fd == -1) { perror("Can't open file"); return 1; } res = fcntl(fd, F_SETLEASE, F_WRLCK); if (res == -1) { perror("Can't set lease"); return 1; } show_lease(fd); if (flock(fd, LOCK_SH) == -1) { perror("Can't flock shared"); return 1; } show_lease(fd); return 0; } The first call to show_lease() will show the write lease set, but the second will show no leases.

2007-09-11Restore call_usermodehelper_pipe() behaviourMichael Ellerman
The semantics of call_usermodehelper_pipe() used to be that it would fork the helper, and wait for the kernel thread to be started. This was implemented by setting sub_info.wait to 0 (implicitly), and doing a wait_for_completion(). As part of the cleanup done in 0ab4dc92278a0f3816e486d6350c6652a72e06c8, call_usermodehelper_pipe() was changed to pass 1 as the value for wait to call_usermodehelper_exec(). This is equivalent to setting sub_info.wait to 1, which is a change from the previous behaviour. Using 1 instead of 0 causes __call_usermodehelper() to start the kernel thread running wait_for_helper(), rather than directly calling ____call_usermodehelper(). The end result is that the calling kernel code blocks until the user mode helper finishes. As the helper is expecting input on stdin, and now no one is writing anything, everything locks up (observed in do_coredump). The fix is to change the 1 to UMH_WAIT_EXEC (aka 0), indicating that we want to wait for the kernel thread to be started, but not for the helper to finish.

2007-09-11futex_compat: fix list traversal bugsArnd Bergmann
The futex list traversal on the compat side appears to have a bug. It's loop termination condition compares: while (compat_ptr(uentry) != &head->list) But that can't be right because "uentry" has the special "pi" indicator bit still potentially set at bit 0. This is cleared by fetch_robust_entry() into the "entry" return value. What this seems to mean is that the list won't terminate when list iteration gets back to the the head. And we'll also process the list head like a normal entry, which could cause all kinds of problems. So we should check for equality with "entry". That pointer is of the non-compat type so we have to do a little casting to keep the compiler and sparse happy. The same problem can in theory occur with the 'pending' variable, although that has not been reported from users so far. Based on the original patch from David Miller.

If the quirk enables the SIR part of the SMCf010 device, the 8250 driver may claim it as a legacy ttyS device, which makes the legacy probe in the smsc-ircc2 driver fail.

2007-09-11spi_mpc83xx: hang fixJan Andersson
When the spi_mpc83xx driver receives a tx_buf pointer which is NULL, it only writes one zero filled word to the transmit register. If the driver expects to receive more than one word it will wait forever for a second receive interrupt. With this patch the controller will shift out zeroes until all words have been received.
