[SPARC64]: Get DEBUG_PAGEALLOC working again. We have to make sure to use base-pagesize TLB entries even during the early transition period where we need TLB miss handling but don't have the kernel page tables setup yet for the linear region. Also, it is necessary therefore to not use the 4MB TSB for these translations, and instead use the normal kernel TSB. This allows us to also get rid of the 4MB tsb for debug builds which shrinks the kernel a little bit. Signed-off-by:

[IPV6]: ipv6_fl_socklist is inadvertently shared. The ipv6_fl_socklist from listening socket is inadvertently shared with new socket created for connection. This leads to a variety of interesting, but fatal, bugs. For example, removing one of the sockets may lead to the other socket's encountering a page fault when the now freed list is referenced. The fix is to not share the flow label list with the new socket. Signed-off-by:

[IPV4]: Do not disable preemption in trie_leaf_remove(). Hello, Just discussed this Patrick... We have two users of trie_leaf_remove, fn_trie_flush and fn_trie_delete both are holding RTNL. So there shouldn't be need for this preempt stuff. This is assumed to a leftover from an older RCU-take. > Mhh .. I think I just remembered something - me incorrectly suggesting > to add it there while we were talking about this at OLS :) IIRC the > idea was to make sure tnode_free (which at that time didn't use > call_rcu) wouldn't free memory while still in use in a rcu read-side > critical section. It should have been synchronize_rcu of course, > but with tnode_free using call_rcu it seems to be completely > unnecessary. So I guess we can simply remove it. Signed-off-by:

[XFRM]: Fix missing protocol comparison of larval SAs. I noticed that in xfrm_state_add we look for the larval SA in a few places without checking for protocol match. So when using both AH and ESP, whichever one gets added first, deletes the larval SA. It seems AH always gets added first and ESP is always the larval SA's protocol since the xfrm->tmpl has it first. Thus causing the additional km_query() Adding the check eliminates accidental double SA creation. Signed-off-by:

When iterating through an array, one must be careful to test one's index variable rather than another similarly-named variable. The loop will read off the end of conf->disks[] in the following (pathological) case: % dd bs=1 seek=840716287 if=/dev/zero of=d1 count=1 % for i in 2 3 4; do dd if=/dev/zero of=d$i bs=1k count=$(($i+150)); done % ./vmlinux ubd0=root ubd1=d1 ubd2=d2 ubd3=d3 ubd4=d4 # mdadm -C /dev/md0 --level=linear --raid-devices=4 /dev/ubd[1234] adding some printks, I saw this: [42949374.960000] hash_spacing = 821120 [42949374.960000] cnt = 4 [42949374.960000] min_spacing = 801 [42949374.960000] j=0 size=820928 sz=820928 [42949374.960000] i=0 sz=820928 hash_spacing=820928 [42949374.960000] j=1 size=64 sz=64 [42949374.960000] j=2 size=64 sz=128 [42949374.960000] j=3 size=64 sz=192 [42949374.960000] j=4 size=1515870810 sz=1515871002 Cc: Gautham R Shenoy <ego@in.ibm.com> Acked-by:

hrtimer_forward() does not check for the possible overflow of timer->expires. This can happen on 64 bit machines with large interval values and results currently in an endless loop in the softirq because the expiry value becomes negative and therefor the timer is expired all the time. Check for this condition and set the expiry value to the max. expiry time in the future. The fix should be applied to stable kernel series as well. Signed-off-by:

Looks like we need a check in nfs_getattr() for a regular file. It makes no sense to call nfs_sync_mapping_range() on anything else. I think that should fix your problem: it will stop the NFS client from interfering with dirty pages on that inode's mapping. Signed-off-by:

adjust legacy IDE resource setting (v2) The change to force legacy mode IDE channels' resources to fixed non-zero values confuses (at least some versions of) X, because the values reported by the kernel and those readable from PCI config space aren't consistent anymore.

The current CIPSO engine has a problem where it does not verify that the given sensitivity level has a valid CIPSO mapping when the "std" CIPSO DOI type is used. The end result is that bad packets are sent on the wire which should have never been sent in the first place. This patch corrects this problem by verifying the sensitivity level mapping similar to what is done with the category mapping. This patch also changes the returned error code in this case to -EPERM to better match what the category mapping verification code returns. Signed-off-by:

Recent alterations to the gdth_fill_raw_cmd() path no longer set the sg_ranz field for zero transfer commands. However, this field is used lower down in the function to initialise ha->cmd_len to the size of the firmware packet. If this uninitialised field contains a bogus value, ha->cmd_len can become much larger than the actual firmware packet and end up oopsing in gdth_copy_cmd() as it tries to copy this huge packet to the device (usually because it runs into an unallocated page). The fix is to initialise the sg_ranz field to zero at the start of gdth_fill_raw_cmd(). Signed-off-by:

[SPARC]: Fix bus handling in build_device_resources(). We mistakedly modify 'bus' in the innermost loop. What should happen is that at each register index iteration, we start with the same 'bus'. So preserve it's value at the top level, and use a loop local variable 'dbus' for iteration. This bug causes registers other than the first to be decoded improperly. Signed-off-by:

At least the Keyspan USA-19HS USB-to-serial converter supports two different configurations, one where the input endpoints have interrupt transfer type and one where they are bulk endpoints. The default UHCI configuration uses the interrupt input endpoints. The keyspan driver, OTOH, assumes that the device has only bulk endpoints (all URBs are initialized by calling usb_fill_bulk_urb in keyspan.c/ keyspan_setup_urb). This causes the interval field of the input URBs to have a value of zero instead of one, which 'accidentally' worked with Linux at least up to 2.6.17.11 but stopped to with 2.6.18, which changed the UHCI support code handling URBs for interrupt endpoints. The patch below modifies to driver to initialize its input URBs either as interrupt or as bulk URBs, depending on the transfertype contained in the associated endpoint descriptor (only tested with the default configuration) enabling the driver to again receive data from the serial converter. Greg K-H reworked the patch. Signed-off-by:

Some versions of the bcm43xx chips only support 30-bit DMA, which means that the descriptors and buffers must be in the first 1 GB of RAM. On the i386 and x86_64 architectures with more than 1 GB RAM, an incorrect assignment may occur. This patch ensures that the various DMA addresses are within the capability of the chip. Testing has been limited to x86_64 as no one has an i386 system with more than 1 GB RAM. Signed-off-by:

[NETFILTER]: nf_conntrack: fix incorrect classification of IPv6 fragments as ESTABLISHED The individual fragments of a packet reassembled by conntrack have the conntrack reference from the reassembled packet attached, but nfctinfo is not copied. This leaves it initialized to 0, which unfortunately is the value of IP_CT_ESTABLISHED. The result is that all IPv6 fragments are tracked as ESTABLISHED, allowing them to bypass a usual ruleset which accepts ESTABLISHED packets early. Signed-off-by:
