2007-03-25[NET]: Fix neighbour destructor handling.Alexey Kuznetsov
->neigh_destructor() is killed (not used), replaced with ->neigh_cleanup(), which is called when neighbor entry goes to dead state. At this point everything is still valid: neigh->dev, neigh->parms etc. The device should guarantee that dead neighbor entries (neigh->dead != 0) do not get private part initialized, otherwise nobody will cleanup it. I think this is enough for ipoib which is the only user of this thing. Initialization private part of neighbor entries happens in ipib start_xmit routine, which is not reached when device is down. But it would be better to add explicit test for neigh->dead in any case. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-03-25[NET]: Fix fib_rules compatibility breakageThomas Graf
Based upon a patch from Patrick McHardy. The fib_rules netlink attribute policy introduced in 2.6.19 broke userspace compatibilty. When specifying a rule with "from all" or "to all", iproute adds a zero byte long netlink attribute, but the policy requires all addresses to have a size equal to sizeof(struct in_addr)/sizeof(struct in6_addr), resulting in a validation error. Check attribute length of FRA_SRC/FRA_DST in the generic framework by letting the family specific rules implementation provide the length of an address. Report an error if address length is non zero but no address attribute is provided. Fix actual bug by checking address length for non-zero instead of relying on availability of attribute.

It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

2007-03-23[PATCH] i386: clear segment register padding in core dumpsRoland McGrath
The segment register slots in struct pt_regs are padded to 32 bits. Some of these are stored with instructions like "pushl %es", which leaves the high 16 bits as they were. So the high bits of these fields in struct pt_regs contain kernel stack garbage. These bits are ignored by everything and never leak to user space, except in core dumps. The user struct pt_regs is always at the base of the thread's kernel stack and so it seems unlikely the information that leaks from here is ever worthwhile so as to be a security concern, but I'm not sure about that. It has been this way for ages; userland consumers of core dumps all mask off these high bits themselves. So it is not urgent. This change masks off the padding bits of the segment register slots in core dumps. ptrace already masks off these high bits, so this makes the values in core dumps consistent with what ptrace would report just before the process died. As I read the processor manuals, the cs and ss values will always be padded with zero bits rather than stack garbage. But unlike "pushl %es", this is not simple to test with a userland program. So I added the two instructions rather than wonder if they are really never necessary. I think that x86_64 does not have this problem (for either 32-bit or 64-bit processes). It only uses "mov" instructions from segment registers, which zero-extend. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception.

2007-03-20[IA64] min_low_pfn and max_low_pfn calculation fixZou Nan hai
We have seen bad_pte_print when testing crashdump on an SN machine in recent 2.6.20 kernel. There are tons of bad pte print (pfn < max_low_pfn) reports when the crash kernel boots up, all those reported bad pages are inside initmem range; That is because if the crash kernel code and data happens to be at the beginning of the 1st node. build_node_maps in discontig.c will bypass reserved regions with filter_rsvd_memory. Since min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn will be greater than kernel code and data. Because pages inside initmem are freed and reused later, we saw pfn_valid check fail on those pages. I think this theoretically happen on a normal kernel. When I check min_low_pfn and max_low_pfn calculation in contig.c and discontig.c. I found more issues than this. 1. min_low_pfn and max_low_pfn calculation is inconsistent between contig.c and discontig.c, min_low_pfn is calculated as the first page number of boot memmap in contig.c (Why? Though this may work at the most of the time, I don't think it is the right logic). It is calculated as the lowest physical memory page number bypass reserved regions in discontig.c. max_low_pfn is calculated include reserved regions in contig.c. It is calculated exclude reserved regions in discontig.c. 2. If kernel code and data region is happen to be at the begin or the end of physical memory, when min_low_pfn and max_low_pfn calculation is bypassed kernel code and data, pages in initmem will report bad. 3. initrd is also in reserved regions, if it is at the begin or at the end of physical memory, kernel will refuse to reuse the memory. Because the virt_addr_valid check in free_initrd_mem. So it is better to fix and clean up those issues. Calculate min_low_pfn and max_low_pfn in a consistent way.

2007-03-20[SCTP]: Reset some transport and association variables on restartVlad Yasevich
If the association has been restarted, we need to reset the transport congestion variables as well as accumulated error counts and CACC variables. If we do not, the association will use the wrong values and may terminate prematurely. This was found with a scenario where the peer restarted the association when lksctp was in the last HB timeout for its association. The restart happened, but the error counts have not been reset and when the timeout occurred, a newly restarted association was terminated due to excessive retransmits.

The current NFS client congestion logic is severly broken, it marks the backing device congested during each nfs_writepages() call but doesn't mirror this in nfs_writepage() which makes for deadlocks. Also it implements its own waitqueue. Replace this by a more regular congestion implementation that puts a cap on the number of active writeback pages and uses the bdi congestion waitqueue. Also always use an interruptible wait since it makes sense to be able to SIGKILL the process even for mounts without 'intr'.

It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

2007-03-16[PATCH] spi: destroy workqueue after spi_unregister_masterChris Lesiak
Fix a bug in the cleanup of an spi_bitbang bus. The workqueue associated with the bus was destroyed before the call to spi_unregister_master. That meant that spi devices on that bus would be unable to do IO in their remove method. The shutdown flag should have been able to prevent a segfault, but was never getting set. By waiting to destroy the workqueue until after the master is unregistered, devices are able to do IO in their remove methods. An added benefit is that neither the shutdown flag nor a wait for the queue of messages to empty is needed.

2007-03-16[PATCH] ufs2: more correct work with timeEvgeniy Dushistov
This patch corrects work with time in UFS2 case. 1) According to UFS2 disk layout modification/access and so on "time" should be hold in two variables one 64bit for seconds and another 32bit for nanoseconds, at now for some unknown reason we suppose that "inode time" holds in three variables 32bit for seconds, 32bit for milliseconds and 32bit for nanoseconds. 2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of getting values from "on disk inode"(this should close http://bugzilla.kernel.org/show_bug.cgi?id=7991).
