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. I'm using it with PAL TV (using RGB input - SCART connector) and the bug prevented it from working at all (TV requirements are more strict and made the bug visible). Signed-off-by:

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.

Revert commit 656dad31 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. Cc: Christoph Lameter <clameter@sgi.com> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by:

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. Fix the flock adding so that the leases always stay in the head of this list. Found during making the flocks pid-namespaces aware. Signed-off-by:Pavel Emelyanov <xemul@openvz.org> Acked-by:

Taneli Vähäkangas <vahakang@cs.helsinki.fi> reported that commit 786d7e16 aka "Fix rmmod/read/write races in /proc entries" broke SBCL + SLIME combo. The old code in do_select() used DEFAULT_POLLMASK, if couldn't find ->poll handler. The new code makes ->poll always there and returns 0 by default, which is not correct. Return DEFAULT_POLLMASK instead. Steps to reproduce: install emacs, SBCL, SLIME emacs M-x slime in *inferior-lisp* buffer [watch it doing "Connecting to Swank on port X.."] Please, apply before 2.6.23. P.S.: why SBCL can't just read(2) /proc/cpuinfo is a mystery. Signed-off-by:

Michael Ellerman authored
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 0ab4dc92, 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. Signed-off-by:

I ran into a few problems. n_tty_ioctl() for instance: drivers/char/tty_ioctl.c:799: error: $,1rxstruct termios$,1ry has no member named $,1rxc_ispeed$,1ry This is calling the copy interface that is supposed to be using a termios2 when the new interfaces are defined, however: case TIOCGLCKTRMIOS: if (kernel_termios_to_user_termios((struct termios __user *)arg, real_tty->termios_locked)) return -EFAULT; return 0; This is going to write over the end of the userspace structure by a few bytes, and wasn't caught by you yet because the i386 implementation is simply copy_to_user() which does zero type checking.

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.

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.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs to account for this in the udma_filter() method. In order to achieve that, do the following changes: - install the method for all chips, not only HPT36x/370 and improve the code formatting by killing the extra tabs while at it; - add to the end of the 'switch' statement in the method cases for HPT372[AN] and HPT374 chips upon which the known SATA cards are based; - use hwif->ultra_mask as a default mask for the ide_dma_filter() method to behave correctly; - move the HPT370[A] cases below the HPT36x case for consistency. While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants all over the driver... Signed-off-by:

The IDE core never marked the PCI IDE devices as being in use after succesfull driver probe call (the devices were marked in use only while being probed), and so was susceptible to issues caused by unsolicited PCI hotplug device removal. So, add pci_dev_get() call to ide_scan_pcidev() and convert this function to the kernel style, also dropping a bunch of useless curly braces from its caller, ide_scan_pcibus() and somewhat beautifying printk() call there, while at it...
