2008-12-17USB: add 5372:2303 to pl2303Matthew Arnold
This patch adds the "Superial" USB-Serial converter to pl2303 so that it is detected, by the correct driver. Adds the relevant vendor:product (5372:2303) to the device tables in pl2303.c & pl2303.h.

2008-12-17USB: skip Set-Interface(0) if already in altsetting 0Alan Stern
When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0. Unforunately, quite a few devices have buggy firmware that crashes when it receives this request. To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

2008-12-17USB: fix comment about endianness of descriptorsPhil Endecott
This patch fixes a comment and clarifies the documentation about the endianness of descriptors. The current policy is that descriptors will be little-endian at the API even on big-endian systems; however the /proc/bus/usb API predates this policy and presents descriptors with some multibyte fields byte-swapped.

2008-12-16[SCSI] mpt fusion: clear list of outstanding commands on host resetJames Bottomley
A bug in the fusion driver was exposed by the switch to block timeout. Basically, drivers are supposed to terminate commands once error handling begins on them. The fusion apparently wasn't doing this. Under the old timeout regime, completions on terminated commands would by and large get ignored because of the way command timeouts used to work. The new block timers are very intolerant to this, though, becuase the request gets cleaned and freed.

2008-12-16tlan: Fix small (< 64 bytes) datagram transmissionsSakari Ailus
The TLAN chip does not support tranmissions smaller than 64 bytes. Smaller transfers need to be padded up to that size. This was broken by commit id 41873e9aff0632d80c74380d58a89e8d420151bd ("tlan: get rid of padding buffer"). <URL:http://bugzilla.kernel.org/show_bug.cgi?id=11754> Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: David S.

2008-12-16netfilter: ctnetlink: fix missing CTA_NAT_SEQ_UNSPECPablo Neira Ayuso
This patch fixes an inconsistency in nfnetlink_conntrack.h that I introduced myself. The problem is that CTA_NAT_SEQ_UNSPEC is missing from enum ctattr_natseq. This inconsistency may lead to problems in the message parsing in userspace (if the message contains the CTA_NAT_SEQ_* attributes, of course). This patch breaks backward compatibility, however, the only known client of this code is libnetfilter_conntrack which indeed crashes because it assumes the existence of CTA_NAT_SEQ_UNSPEC to do the parsing. The CTA_NAT_SEQ_* attributes were introduced in 2.6.25. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-12-16powerpc/cell/axon-msi: Fix MSI after kexecArnd Bergmann
Commit d015fe995 'powerpc/cell/axon-msi: Retry on missing interrupt' has turned a rare failure to kexec on QS22 into a reproducible error, which we have now analysed. The problem is that after a kexec, the MSIC hardware still points into the middle of the old ring buffer. We set up the ring buffer during reboot, but not the offset into it. On older kernels, this would cause a storm of thousands of spurious interrupts after a kexec, which would most of the time get dropped silently. With the new code, we time out on each interrupt, waiting for it to become valid. If more interrupts come in that we time out on, this goes on indefinitely, which eventually leads to a hard crash. The solution in this commit is to read the current offset from the MSIC when reinitializing it. This now works correctly, as expected.

2008-12-16powerpc: Fix bootmem reservation on uninitialized nodeDave Hansen
careful_allocation() was calling into the bootmem allocator for nodes which had not been fully initialized and caused a previous bug: http://patchwork.ozlabs.org/patch/10528/ So, I merged a few broken out loops in do_init_bootmem() to fix it. That changed the code ordering. I think this bug is triggered by having reserved areas for a node which are spanned by another node's contents. In the mark_reserved_regions_for_nid() code, we attempt to reserve the area for a node before we have allocated the NODE_DATA() for that nid. We do this since I reordered that loop. I suck. This is causing crashes at bootup on some systems, as reported by Jon Tollefson. This may only present on some systems that have 16GB pages reserved. But, it can probably happen on any system that is trying to reserve large swaths of memory that happen to span other nodes' contents. This commit ensures that we do not touch bootmem for any node which has not been initialized, and also removes a compile warning about an unused variable.

2008-12-16powerpc: Check for valid hugepage size in hugetlb_get_unmapped_areaBrian King
It looks like most of the hugetlb code is doing the correct thing if hugepages are not supported, but the mmap code is not. If we get into the mmap code when hugepages are not supported, such as in an LPAR which is running Active Memory Sharing, we can oops the kernel. This fixes the oops being seen in this path. oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=1024 NUMA pSeries Modules linked in: nfs(N) lockd(N) nfs_acl(N) sunrpc(N) ipv6(N) fuse(N) loop(N) dm_mod(N) sg(N) ibmveth(N) sd_mod(N) crc_t10dif(N) ibmvscsic(N) scsi_transport_srp(N) scsi_tgt(N) scsi_mod(N) Supported: No NIP: c000000000038d60 LR: c00000000003945c CTR: c0000000000393f0 REGS: c000000077e7b830 TRAP: 0300 Tainted: G (2.6.27.5-bz50170-2-ppc64) MSR: 8000000000009032 <EE,ME,IR,DR> CR: 44000448 XER: 20000001 DAR: c000002000af90a8, DSISR: 0000000040000000 TASK = c00000007c1b8600[4019] 'hugemmap01' THREAD: c000000077e78000 CPU: 6 GPR00: 0000001fffffffe0 c000000077e7bab0 c0000000009a4e78 0000000000000000 GPR04: 0000000000010000 0000000000000001 00000000ffffffff 0000000000000001 GPR08: 0000000000000000 c000000000af90c8 0000000000000001 0000000000000000 GPR12: 000000000000003f c000000000a73880 0000000000000000 0000000000000000 GPR16: 0000000000000000 0000000000000000 0000000000000000 0000000000010000 GPR20: 0000000000000000 0000000000000003 0000000000010000 0000000000000001 GPR24: 0000000000000003 0000000000000000 0000000000000001 ffffffffffffffb5 GPR28: c000000077ca2e80 0000000000000000 c00000000092af78 0000000000010000 NIP [c000000000038d60] .slice_get_unmapped_area+0x6c/0x4e0 LR [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 Call Trace: [c000000077e7bbc0] [c00000000003945c] .hugetlb_get_unmapped_area+0x6c/0x80 [c000000077e7bc30] [c000000000107e30] .get_unmapped_area+0x64/0xd8 [c000000077e7bcb0] [c00000000010b140] .do_mmap_pgoff+0x140/0x420 [c000000077e7bd80] [c00000000000bf5c] .sys_mmap+0xc4/0x140 [c000000077e7be30] [c0000000000086b4] syscall_exit+0x0/0x40 Instruction dump: fac1ffb0 fae1ffb8 fb01ffc0 fb21ffc8 fb41ffd0 fb61ffd8 fb81ffe0 fbc1fff0 fbe1fff8 f821fef1 f8c10158 f8e10160 <7d49002e> f9010168 e92d01b0 eb4902b0 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
