Fix MAP_PRIVATE mmap() of files and devices where the data in the backing store might be mapped directly. Use the BDI_CAP_MAP_DIRECT capability flag to govern whether or not we should be trying to map a file directly. This can be used to determine whether or not a region has been filled in at the point where we call do_mmap_shared() or do_mmap_private(). The BDI_CAP_MAP_DIRECT capability flag is cleared by validate_mmap_request() if there's any reason we can't use it. It's also cleared in do_mmap_pgoff() if f_op->get_unmapped_area() fails. Without this fix, attempting to run a program from a RomFS image on a non-mappable MTD partition results in a BUG as the kernel attempts XIP, and this can be caught in gdb: Program received signal SIGABRT, Aborted. 0xc005dce8 in add_nommu_region (region=<value optimized out>) at mm/nommu.c:547 (gdb) bt #0 0xc005dce8 in add_nommu_region (region=<value optimized out>) at mm/nommu.c:547 #1 0xc005f168 in do_mmap_pgoff (file=0xc31a6620, addr=<value optimized out>, len=3808, prot=3, flags=6146, pgoff=0) at mm/nommu.c:1373 #2 0xc00a96b8 in elf_fdpic_map_file (params=0xc33fbbec, file=0xc31a6620, mm=0xc31bef60, what=0xc0213144 "executable") at mm.h:1145 #3 0xc00aa8b4 in load_elf_fdpic_binary (bprm=0xc316cb00, regs=<value optimized out>) at fs/binfmt_elf_fdpic.c:343 #4 0xc006b588 in search_binary_handler (bprm=0x6, regs=0xc33fbce0) at fs/exec.c:1234 #5 0xc006c648 in do_execve (filename=<value optimized out>, argv=0xc3ad14cc, envp=0xc3ad1460, regs=0xc33fbce0) at fs/exec.c:1356 #6 0xc0008cf0 in sys_execve (name=<value optimized out>, argv=0xc3ad14cc, envp=0xc3ad1460) at arch/frv/kernel/process.c:263 #7 0xc00075dc in __syscall_call () at arch/frv/kernel/entry.S:897 Note that this fix does the following commit differently: commit a190887b Author: David Howells <dhowells@redhat.com> Date: Sat Sep 5 11:17:07 2009 -0700 nommu: fix error handling in do_mmap_pgoff() Reported-by:

Note that .data.page_aligned and .data.cacheline_aligned are now after _data; it was probably a bug that they were before it. Also, some explicit ALIGN(8)'s between various initcall sections were removed; this should be harmless as the implicit alignment of initcall_t was already 8. Signed-off-by:

alpha is the only architecture that uses the section name .data.init_thread instead of .data.init_task. So convert alpha to use .data.init_task like everything else. .data.init_task does not need a separate output section; this change also moves it into the .data output section. Signed-off-by:

This patch has the (likely harmless) side effect of moving .data.init_task inside the _edata. It also changes the alignment of .data.init_task from 16384 to THREAD_SIZE, which can in some configurations be larger than 16384. I believe that this change fixes a potential bug on those configurations. Signed-off-by:

Tim Abbott authored
The old RW_DATA_SECTION had INIT_TASK_DATA (which was more-than-PAGE_SIZE-aligned), followed by a bunch of small alignment stuff, followed by more PAGE_SIZE-aligned stuff, so you wasted memory in the middle of .data re-aligning back up to PAGE_SIZE. This patch sorts the sections by alignment requirements, which should pack them essentially optimally. Signed-off-by:

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e68 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq(). Signed-off-by:

It seems recursion field from "struct ip_tunnel" is not anymore needed. recursion prevention is done at the upper level (in dev_queue_xmit()), since we use HARD_TX_LOCK protection for tunnels. This avoids a cache line ping pong on "struct ip_tunnel" : This structure should be now mostly read on xmit and receive paths. Signed-off-by:

Previous update did not resched in inner loop causing watchdogs. Rewrite inner loop to: * account for delays better with less clock calls * more accurate timing of delay: - only delay if packet was successfully sent - if delay is 100ns and it takes 10ns to build packet then account for that * use wait_event_interruptible_timeout rather than open coding it.

Due to man page of setsockopt, if optlen is not valid, kernel should return -EINVAL. But a simple testcase as following, errno is 0, which means setsockopt is successful. addr.s_addr = inet_addr("192.1.2.3"); setsockopt(s, IPPROTO_IP, IP_MULTICAST_IF, &addr, 1); printf("errno is %d\n", errno); Xiaotian Feng(dfeng@redhat.com) caught the bug. We fix it firstly checking the availability of optlen and then dealing with the logic like other options. Reported-by:Xiaotian Feng <dfeng@redhat.com> Signed-off-by:

Multicast joins can succeed even if the IB port is down. This happens when the SM runs on the same port with the requesting port. However, IPoIB calls netif_carrier_on() when the join of the broadcast group succeeds, without caring about the state of the IB port. The result is an IPoIB interface in RUNNING state but without an active IB port to support it. If a bonding interface uses this IPoIB interface as a slave it might not detect that this slave is almost useless and failover functionality will be damaged. The fix checks the state of the IB port in the carrier_task before calling netif_carrier_on(). Adresses: https://bugs.openfabrics.org/show_bug.cgi?id=1726Signed-off-by:
