The PIT has no dedicated mode for shut down. The only way to disable PIT is to put it into one shot mode. AMD implementations of PIT on Geode (also observed on Cyrix) are confused by an "empty" transition from CLOCK_EVT_MODE_UNUSED to CLOCK_EVT_MODE_SHUTDOWN, which puts the PIT into one shot mode momentarily. I realized after staring helpless at the bug report http://bugzilla.kernel.org/show_bug.cgi?id=8027 for quite a while, that the only change, which might influence the bogomips calibration, is the above transition during the PIT initialization. Avoiding the unnecessary switch to oneshot and later to periodic mode fixes the weird bogomips value and also the resulting slowness. The fix is confirmed on OLPC and another Geode based box.

The packet length checks in ipoib are broken: we add 4 bytes (IPoIB encapsulation header) when sending a packet, not 20 bytes (hardware address length) to each packet. Therefore, if connected mode is enabled so that the interface MTU is larger than the multicast MTU, IPoIB may end up trying to send too-long multicast packets. For example, multicast is broken if a message of size 2048 bytes is sent on an interface with UD MTU 2048, because 2048 is bigger than the real limit of 2044 but the code tests against the wrong limit of 2060.

There's a race between ipoib_mcast_leave() and ipoib_mcast_join_finish() where we can try to detach from a multicast group before we've attached to it. Fix this by reordering the code in ipoib_mcast_leave to free the multicast group first, which waits for the multicast callback thread (which calls ipoib_mcast_join_finish()) to complete before detaching from the group.

Currently NAT not only reroutes packets in the OUTPUT chain when the routing key changed, but also if only the non-routing part of the IPsec policy key changed. This breaks ping -I since it doesn't use SO_BINDTODEVICE but IP_PKTINFO cmsg to specify the output device, and this information is lost. Only do full rerouting if the routing key changed, and just do a new policy lookup with the old route if only the ports changed.

there is a tiny bug in Documentation/crypto/api-intro.txt. The file has the following example code: struct scatterlist sg[2]; [...] if (crypto_hash_digest(&desc, &sg, 2, result)) which does not match the declaration of crypto_hash_digest() in include/linux/crypto.h. (static inline int crypto_hash_digest(struct hash_desc *desc, struct scatterlist *sg, unsigned int nbytes, u8 *out) The code in the example passes the address of a pointer (an array actually) as the second argument, while the function expects the pointer itself. I have attached a patch to fix this. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

In the loop in scatterwalk_copychunks(), if walk->offset is zero, then scatterwalk_pagedone rounds that up to the nearest page boundary: walk->offset += PAGE_SIZE - 1; walk->offset &= PAGE_MASK; which is a no-op in this case, so we don't advance to the next element of the scatterlist array: if (walk->offset >= walk->sg->offset + walk->sg->length) scatterwalk_start(walk, sg_next(walk->sg)); and we end up copying the same data twice. It appears that other callers of scatterwalk_{page}done first advance walk->offset, so I believe that's the correct thing to do here. This caused a bug in NFS when run with krb5p security, which would cause some writes to fail with permissions errors--for example, writes of less than 8 bytes (the des blocksize) at the start of a file. A git-bisect shows the bug was originally introduced by 5c64097a, first in 2.6.19-rc1. Signed-off-by: N"J.

In sn_io_slot_fixup(), the parent is re-set from the bus to io(port|mem)_resource because the address is changed in a way that it's not child of the bus any more. However, only the root is set but not the parent/child/sibling relationship in the resource tree which causes 'cat /proc/iomem' to stop after this memory area. Depding on the poition in the tree the iomem may be nearly completely empty.

When booting an SN system without specifing a console (i.e., no "console=" on boot line), the system will hang during boot at the point where /sbin/init is run. The problem is that vga_console_iobase is not converted to a virtual address before storing in io_space[0].mmio_base. The conversion was happening in sn_scan_pcdp(), but not in setup_vga_console().

If a system consists of mixed processor types, kmalloc() can be called before the per-cpu data page is initialized. If the slab contains sufficient memory, then kmalloc() works ok. However, if the slabs are empty, slab calls the memory allocator. This requires per-cpu data (NODE_DATA()) & the cpu dies. Also noted by Russ Anderson who had a very similar patch.

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.

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.
