2008-01-18atl1: fix frame length bugJay Cliburn
The driver sets up the hardware to accept a frame with max length equal to MTU + Ethernet header + FCS + VLAN tag, but we neglect to add the VLAN tag size to the ingress buffer. When a VLAN-tagged frame arrives, the hardware passes it, but bad things happen because the buffer is too small. This patch fixes that. Thanks to David Harris for reporting the bug and testing the fix.

2008-01-18bonding: Don't hold lock when calling rtnl_unlockJay Vosburgh
Change bond_mii_monitor to not hold any locks when calling rtnl_unlock, as rtnl_unlock can sleep (when acquring another mutex in netdev_run_todo).

2008-01-18bonding: fix lock ordering for rtnl and bonding_rwsemJay Vosburgh
Fix the handling of rtnl and the bonding_rwsem to always be acquired in a consistent order (rtnl, then bonding_rwsem). The existing code sometimes acquired them in this order, and sometimes in the opposite order, which opens a window for deadlock between ifenslave and sysfs.

2008-01-18bonding: Fix up parameter parsingJay Vosburgh
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).

2008-01-18bonding: release slaves when master removed via sysfsJay Vosburgh
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.

2008-01-18bonding: fix locking during alb failover and slave removalJay Vosburgh
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.

2008-01-18bonding: fix ASSERT_RTNL that produces spurious warningsJay Vosburgh
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>
2008-01-18bonding: fix locking in sysfs primary/active selectionJay Vosburgh
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).

2008-01-17#ifdef very expensive debug check in page fault pathCarsten Otte
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.

2008-01-17CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common definesJesper Nilsson
- 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__.

2008-01-17cpufreq: Initialise default governor before useJohannes Weiner
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.

The Tx skb release could not free more than one skb per call. Add it to the fact that the xmit handler does not check for a queue full condition and you have a recipe to leak quickly. Let's release every pending Tx descriptor which has been given back to the host CPU by the network controller. The xmit handler suggests that it is done through the IPG_TFC_TFDDONE bit.

Fix a buffer overflow in mutli-packet handling code.

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.

2008-01-17Input: mousedev - handle mice that use absolute coordinatesMicah Parrish
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>
