2011-06-08MD: no sync IO while suspendedJonathan Brassow1-1/+3
Disallow resync I/O while the RAID array is suspended. Recovery, resync, and metadata I/O should not be allowed while a device is suspended. Signed-off-by: Jonathan Brassow <[email protected]> Signed-off-by: NeilBrown <[email protected]>
2011-06-08MD: no integrity register if no gendiskJonathan Brassow1-2/+2
Don't attempt md_integrity_register if there is no gendisk struct available. When MD arrays are built via device-mapper, the gendisk structure is not available via mddev. Signed-off-by: Jonathan Brassow <[email protected]> Signed-off-by: NeilBrown <[email protected]>
2011-06-07ceph: unwind canceled flock stateSage Weil1-10/+16
If we request a lock and then abort (e.g., ^C), we need to send a matching unlock request to the MDS to unwind our lock attempt to avoid indefinitely blocking other clients. Reported-by: Brian Chrisman <[email protected]> Signed-off-by: Sage Weil <[email protected]>
2011-06-07ceph: fix ENOENT logic in striped_readSage Weil1-2/+2
Getting ENOENT is equivalent to reading 0 bytes. Make that correction before setting up the hit_stripe and was_short flags. Fixes the following case: dd if=/dev/zero of=/mnt/fs_depot/dd3 bs=1 seek=1048576 count=0 dd if=/mnt/fs_depot/dd3 of=/root/ddout1 skip=8 bs=500 count=2 iflag=direct Reported-by: Henry C Chang <[email protected]> Signed-off-by: Sage Weil <[email protected]>
2011-06-07ceph: fix short sync reads from the OSDSage Weil1-13/+15
If we get a short read from the OSD because the object is small, we need to zero the remainder of the buffer. For O_DIRECT reads, the attempted range is not trimmed to i_size by the VFS, so we were actually looping indefinitely. Fix by trimming by i_size, and the unconditionally zeroing the trailing range.

2011-06-07ceph: use ihold when we already have an inode refSage Weil10-28/+37
We should use ihold whenever we already have a stable inode ref, even when we aren't holding i_lock. This avoids adding new and unnecessary locking dependencies. Signed-off-by: Sage Weil <[email protected]>

2011-06-07MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs()David Howells1-2/+2
die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to indicate that it wants to probe a kernel address. Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

2011-06-07Add support for allocating irqs for bootbus devicesoftedal1-12/+22
Some devices that can generate interrupts are connected directly to the CPU through the bootbus on sun4d. This patch allows IRQs to be allocated for such devices. The information used for allocating interrupts for sbus devices are present at the corresponding SBI node. For bootbus devices this information is present in the bootbus node.

2011-06-07Do not skip interrupt sources in sun4d interrupt handler and acknowledge ↵oftedal1-9/+5
interrupts correctly During the introduction of genirq on sparc32 bugs were introduced in the interrupt handler for sun4d. The interrupts handler checks the status of the various sbus interfaces in the system and generates a virtual interrupt, based upon the location of the interrupt source. This lookup was broken by restructuring the code in such a way that index and shift operations were performed prior to comparing this against the values read from the interrupt controllers. This could cause the handler to loop eternally as the interrupt source could be skipped before any check was performed. Additionally sun4d_encode_irq performs shifting internally, so it should not be performed twice. In sun4d_unmask interrupts were not correctly acknowledged, as the corresponding bit it the interrupt mask was not actually cleared.

2011-06-07Restructure sun4d_build_device_irq so that timer interrupts can be allocatedoftedal1-24/+54
sun4d_build_device_irq was called without a valid platform_device when the system timer was initialized on sun4d systems. This caused a NULL pointer crash. Josip Rodin suggested that the current sun4d_build_device_irq should be split into two functions. So that the timer initialization could skip the slot and sbus interface detection code in sun4d_build_device_irq, as this does not make sence due to the timer interrupts not being generated from a device located on sbus.

2011-06-07libata: fix unexpectedly frozen port after ata_eh_reset()Tejun Heo1-4/+8
To work around controllers which can't properly plug events while reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING after reset but before RESET is marked done. As reset is the final recovery action and full verification of devices including onlineness and classfication match is done afterwards, this shouldn't lead to lost devices or missed hotplug events. Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so if the condition happens after resetting an empty port, the port could be left frozen and EH will end without thawing it, making the port unresponsive to further hotplug events. Thaw if the port is frozen after clearing EH_PENDING. This problem is reported by Bruce Stenning in the following thread. http://thread.gmane.org/gmane.linux.kernel/1123265 stable: I think we should weather this patch a bit longer in -rcX before sending it to -stable.

Many Linux distributions would enable vesafb in order to display early stage boot splash. In this case, we will get garbled X Window screen if running X fbdev on psbfb. This is because fb0 is occupied by vesafb while psbfb is on fb1. They tried to drive the same pieces of hardware at the same time. With unmodified X start-up, it would try to use default fb0 framebuffer device and unfortunately it is now broken becaues fb1 supersedes it. We should let psbfb takeover framebuffer control from vesafb to get around this problem.

2011-06-07staging: gma500: Skip bogus LVDS VBT mode and check for LVDS before adding ↵Patrik Jakobsson2-5/+23
backlight On the Fit-PC2 the VBT reports an invalid fixed panel mode for LVDS, this gets in the way for SDVO. This patch makes VBT parsing skip the invalid mode. When there is no LVDS output the backlight support crashes so the patch also checks for this before enabling it.

2011-06-07staging: usbip: bugfix prevent driver unbindArjan Mels2-9/+32
Implemented pre_reset and post_reset methods of the driver to prevent the driver from being unbound upon a device reset. Because of this also the asynchronous reset introduced to prevent a race condition is no longer necessary (and sometimes causes problems, because it comes later then expected).

Revert the commit that removed the disabling of interrupts around the initial modifying of mcount callers to nops, and update the comment. The original comment was outdated and stated that the interrupts were being disabled to prevent kstop machine, which was required with the old ftrace daemon, but was no longer the case. What the comment failed to mention was that interrupts needed to be disabled to keep interrupts from preempting the modifying of the code and then executing the code that was partially modified.

2011-06-07kprobes/trace: Fix kprobe selftest for gcc 4.6Steven Rostedt1-2/+6
With gcc 4.6, the self test kprobe function: kprobe_trace_selftest_target() is optimized such that kallsyms does not list it. The kprobes test uses this function to insert a probe and test it. But it will fail the test if the function is not listed in kallsyms. Adding a __used annotation keeps the symbol in the kallsyms table.

2011-06-07nl80211: fix overflow in ssid_lenLuciano Coelho1-5/+4
When one of the SSID's length passed in a scan or sched_scan request is larger than 255, there will be an overflow in the u8 that is used to store the length before checking. This causes the check to fail and we overrun the buffer when copying the SSID. Fix this by checking the nl80211 attribute length before copying it to the struct. This is a follow up for the previous commit 208c72f4fe44fe09577e7975ba0e7fa0278f3d03, which didn't fix the problem entirely.
