A recent change to add an additional hash policy modified bond_parse_parm, but it now does not correctly match parameters passed in via sysfs. Rewrote bond_parse_parm to handle (a) parameter matches that are substrings of one another and (b) user input with whitespace (e.g., sysfs input often has a trailing newline).

Add a call to bond_release_all in the bonding netdev event handler for the master. This releases the slaves for the case of, e.g., "echo -bond0 > /sys/class/net/bonding_masters", which otherwise will spin forever waiting for references to be released.

alb_fasten_mac_swap (actually rlb_teach_disabled_mac_on_primary) requries RTNL and no other locks. This could cause dev_set_promiscuity and/or dev_set_mac_address to be called with improper locking. Changed callers to hold only RTNL during calls to alb_fasten_mac_swap or functions calling it. Updated header comments in affected functions to reflect proper reality of locking requirements.

Move an ASSERT_RTNL down to where we should hold only RTNL; the existing check produces spurious warnings because we hold additional locks at _bh, tripping a debug warning in spin_lock_mutex(). Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Fix the functions that store the primary and active slave options via sysfs to hold the correct locks in the correct order. The bond_change_active_slave and bond_select_active_slave functions both require rtnl, bond->lock for read and curr_slave_lock for write_bh, and no other locks. This is so that the lower level mode-specific functions (notably for balance-alb mode) can release locks down to just rtnl in order to call, e.g., dev_set_mac_address with the locks it expects (rtnl only).

Fix http://bugzilla.kernel.org/show_bug.cgi?id=9762 Framebuffer is ok only with default parameters only (it is 1280x800-8@60). If parameters are video=radeonfb:1280x800-32@60 then xres, yres and xres_virtual are ok but yres_virtual is 1024. It can be corrected by fbset utility so I think it can be corrected in the driver code also.

This patch puts #ifdef CONFIG_DEBUG_VM around a check in vm_normal_page that verifies that a pfn is valid. This patch increases performance of the page fault microbenchmark in lmbench by 13% and overall dbench performance by 7% on s390x. pfn_valid() is an expensive operation on s390 that needs a high double digit amount of CPU cycles. Nick Piggin suggested that pfn_valid() involves an array lookup on systems with sparsemem, and therefore is an expensive operation there too. The check looks like a clear debug thing to me, it should never trigger on regular kernels. And if a pte is created for an invalid pfn, we'll find out once the memory gets accessed later on anyway. Please consider inclusion of this patch into mm.

- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD. The reservation up to page size of memory after init data was previously not done if BLK_DEV_INITRD was undefined. This caused a kernel oops when init memory pages were freed after startup, data placed in the same page as the last init memory would also be freed and reused, with disastrous results. - Use macros for initcalls and .text sections. - Replace hardcoded page size constant with PAGE_SIZE define. - Change include/asm-cris/page.h to use the _AC macro to instead of testing __ASSEMBLY__.

Johannes Weiner authored
When the cpufreq driver starts up at boot time, it calls into the default governor which might not be initialised yet. This hurts when the governor's worker function relies on memory that is not yet set up by its init function. This migrates all governors from module_init() to fs_initcall() when being the default, as was already done in cpufreq_performance when it was the only possible choice. The performance governor is always initialized early because it might be used as fallback even when not being the default. Fixes at least one actual oops where ondemand is the default governor and cpufreq_governor_dbs() uses the uninitialised kondemand_wq work-queue during boot-time.

Fix a buffer overflow in mutli-packet handling code. The overflow can only happen with eGalax devices and is even there very unlikely (only non-report packet are affected any only when truncated after the first byte). Also changes the mutli-packet handling code not to drop unknown packets, but rather just drop one byte. This allows synchronizing on report packets in the data stream. It's required for some egalax devices to work at all. Also remove the pointless 'flags' member of the device struct and set the version number to 0.6, plus some minor cleanups.

Devices like the HP Integrated Remote Console Virtual Mouse, which are standard equipment on all Proliant and Integrity servers, produce absolute coordinates instead of relative coordinates. This is done to synchronize the position of the mouse cursor on the client desktop with the mouse cursor position on the server. Mousedev is not designed to pass those absolute events directly to X, but it can translate them into relative movements. It currently does this for tablet like devices and touchpads. This patch merely tells it to also include a device with ABS_X, ABS_Y, and mouse buttons in its list of devices to process input for. This patch enables the mouse pointer to move when using the remote console. Signed-off-by: Micah Parrish <micah.parrish@hp.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

This fixes a regression added by changeset 53e52c72 ("[NET]: Make ->poll() breakout consistent in Intel ethernet drivers.") As pointed out by Jesse Brandeburg, for three of the drivers edited above there is breakout logic in the *_clean_tx_irq() code to prevent running TX reclaim forever. If this occurs, we have to elide NAPI poll completion or else those TX events will never be serviced. Signed-off-by: David S.

sysfs tries to keep dcache a strict subset of sysfs_dirent tree by shooting down dentries when a node is removed, that is, no negative dentry for sysfs. However, the lookup function returned NULL and thus created negative dentries when the target node didn't exist. Make sysfs_lookup() return ERR_PTR(-ENOENT) on lookup failure. This fixes the NULL dereference bug in sysfs_get_dentry() discovered by bluetooth rfcomm device moving around.

Dave Young reported warnings from lockdep that the workqueue API can sometimes try to register lockdep classes with the same key but different names. This is not permitted in lockdep. Unfortunately, I was unaware of that restriction when I wrote the code to debug workqueue problems with lockdep and used the workqueue name as the lockdep class name. This can obviously lead to the problem if the workqueue name is dynamic. This patch solves the problem by always using a constant name for the workqueue's lockdep class, namely either the constant name that was passed in or a string consisting of the variable name.

Luck, Tony authored
The compiler team did the hard work for this distilling a problem in large fortran application which showed up when applied to a 290MB input data set down to this instruction: ldfd f34=[r17],-8 Which they noticed incremented r17 by 0x10 rather than decrementing it by 8 when the value in r17 caused an unaligned data fault. I tracked it down to some bad instruction decoding in unaligned.c. The code assumes that the 'x' bit can determine whether the instruction is an "ldf" or "ldfp" ... which it is for opcode=6 (see table 4-29 on page 3:302 of the SDM). But for opcode=7 the 'x' bit is irrelevent, all variants are "ldf" instructions (see table 4-36 on page 3:306). Note also that interpreting the instruction as "ldfp" means that the "paired" floating point register (f35 in the example here) will also be corrupted. Signed-off-by: Tony Luck <tony.luck@intel.com>
