2013-06-02ARM: bcm2835: override the HW UART periphidJongsung Kim
Stephen Warren reported the recent commit 78506f2 (add support for extended FIFO-size of PL011-r1p5) breaks the serial port on the BCM2835 ARM SoC. A UART compatible with the ARM PL011-r1p5 should have 32-deep FIFOs. The BCM2835 UART just looks like an ARM PL011-r1p5, but has 16-deep FIFOs just like PL011-r1p4 or earlier revisions. As a workaround for this compatibility issue, this patch overrides the HW UART periphid register values with the actually compatible UART periphid 0x00241011 (r1p3 or r1p4).

2013-06-02sata_rcar: fix interrupt handlingSergei Shtylyov
The driver's interrupt handling code is too picky in deciding whether it should handle an interrupt or not which causes completely unneeded spurious interrupts. Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't get cleared by writing to the SATAINTSTAT register in the interrupt mode we use. Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for enabled interrupts and we should clear only those interrupts that we have read as active first time around, because else we have a race and risk clearing an interrupt that can occur between read and write of the SATAINTSTAT register and never registering it...

2013-06-01parisc: memory overflow, 'name' length is too short for usingChen Gang
'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6 * "%u:" + "%u" + '\0') may be 21. Since 'name' length is 20, it may be memory overflow. And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the max length of 'name' must be less than 28. So simplify thinking, we can use 28 instead of 20 directly, and do not think of whether 'patchc.bc[i]' can '> 100'.

We didn't implement them originally because Linux doesn't use them but they are simple and I'm not comfortable having a half-implemented interface in 3.10 and having to deal with versionning etc... later when something starts needing those calls.

2013-05-31xfrm: force a garbage collection after deleting a policyPaul Moore
In some cases after deleting a policy from the SPD the policy would remain in the dst/flow/route cache for an extended period of time which caused problems for SELinux as its dynamic network access controls key off of the number of XFRM policy and state entries. This patch corrects this problem by forcing a XFRM garbage collection whenever a policy is sucessfully removed.

2013-05-31udp6: Fix udp fragmentation for tunnel traffic.Pravin B Shelar
udp6 over GRE tunnel does not work after to GRE tso changes. GRE tso handler passes inner packet but keeps track of outer header start in SKB_GSO_CB(skb)->mac_offset. udp6 fragment need to take care of outer header, which start at the mac_offset, while adding fragment header. This bug is introduced by commit 68c3316311 (GRE: Add TCP segmentation offload for GRE).

2013-05-31net/core: dev_mc_sync_multiple calls wrong helperJay Vosburgh
The dev_mc_sync_multiple function is currently calling __hw_addr_sync, and not __hw_addr_sync_multiple. This will result in addresses only being synced to the first device from the set. Corrected by calling the _multiple variant.

2013-05-31net/core: __hw_addr_sync_one / _multiple brokenJay Vosburgh
Currently, __hw_addr_sync_one is called in a loop by __hw_addr_sync_multiple to sync each of a "from" device's hw addresses to a "to" device. __hw_addr_sync_one calls __hw_addr_add_ex to attempt to add each address. __hw_addr_add_ex is called with global=false, and sync=true. __hw_addr_add_ex checks to see if the new address matches an address already on the list. If so, it tests global and sync. In this case, sync=true, and it then checks if the address is already synced, and if so, returns 0. This 0 return causes __hw_addr_sync_one to increment the sync_cnt and refcount for the "from" list's address entry, even though the address is already synced and has a reference and sync_cnt. This will cause the sync_cnt and refcount to increment without bound every time an addresses is added to the "from" device and synced to the "to" device. The fix here has two parts: First, when __hw_addr_add_ex finds the address already exists and is synced, return -EEXIST instead of 0. Second, __hw_addr_sync_one checks the error return for -EEXIST, and if so, it (a) does not add a refcount/sync_cnt, and (b) returns 0 itself so that __hw_addr_sync_multiple will not return an error.

2013-05-31net/core: __hw_addr_unsync_one "from" address not marked syncedJay Vosburgh
When an address is added to a subordinate interface (the "to" list), the address entry in the "from" list is not marked "synced" as the entry added to the "to" list is. When performing the unsync operation (e.g., dev_mc_unsync), __hw_addr_unsync_one calls __hw_addr_del_entry with the "synced" parameter set to true for the case when the address reference is being released from the "from" list. This causes a test inside to fail, with the result being that the reference count on the "from" address is not properly decremeted and the address on the "from" list will never be freed. Correct this by having __hw_addr_unsync_one call the __hw_addr_del_entry function with the "sync" flag set to false for the "remove from the from list" case.
