Since the ARM AMBA bus is used on MIPS as well as ARM, we need to make the bus available for other architectures to use. Move the AMBA include files from include/asm-arm/hardware/ to include/linux/amba/ Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Patch from Andre McCurdy Replaces generic swab32 routine with a more ARM friendly version. Reduces kernel text size by approx 1200 bytes when compiled with 3.4.4 and approx 2400 bytes with 4.0.2 Probably some performance benefit as well.

I've spent the past 3 days digging into a glibc testsuite failure in current CVS, specifically libc/rt/tst-cputimer1.c The thr1 and thr2 timers fire too early in the second pass of this test. The second pass is noteworthy because it makes use of intervals, whereas the first pass does not. All throughout the posix-cpu-timers.c code, the calculation of the process sched_time sum is implemented roughly as: unsigned long long sum; sum = tsk->signal->sched_time; t = tsk; do { sum += t->sched_time; t = next_thread(t); } while (t != tsk); In fact this is the exact scheme used by check_process_timers(). In the case of check_process_timers(), current->sched_time has just been updated (via scheduler_tick(), which is invoked by update_process_times(), which subsequently invokes run_posix_cpu_timers()) So there is no special processing necessary wrt. that. In other contexts, we have to allot for the fact that tsk->sched_time might be a bit out of date if we are current. And the posix-cpu-timers.c code uses current_sched_time() to deal with that. Unfortunately it does so in an erroneous and inconsistent manner in one spot which is what results in the early timer firing. In cpu_clock_sample_group_locked(), it does this: cpu->sched = p->signal->sched_time; /* Add in each other live thread. */ while ((t = next_thread(t)) != p) { cpu->sched += t->sched_time; } if (p->tgid == current->tgid) { /* * We're sampling ourselves, so include the * cycles not yet banked. We still omit * other threads running on other CPUs, * so the total can always be behind as * much as max(nthreads-1,ncpus) * (NSEC_PER_SEC/HZ). */ cpu->sched += current_sched_time(current); } else { cpu->sched += p->sched_time; } The problem is the "p->tgid == current->tgid" test. If "p" is not current, and the tgids are the same, we will add the process t->sched_time twice into cpu->sched and omit "p"'s sched_time which is very very very wrong. posix-cpu-timers.c has a helper function, sched_ns(p) which takes care of this, so my fix is to use that here instead of this special tgid test. The fact that current can be one of the sub-threads of "p" points out that we could make things a little bit more accurate, perhaps by using sched_ns() on every thread we process in these loops. It also points out that we don't use the most accurate value for threads in the group actively running other cpus (and this is mentioned in the comment). But that is a future enhancement, and this fix here definitely makes sense. Signed-off-by: NDavid S. Miller <davem@davemloft.net> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This patch contains two corrections to the LSM-IPsec Nethooks patches previously applied. (1) free a security context on a failed insert via xfrm_user interface in xfrm_add_policy. Memory leak. (2) change the authorization of the allocation of a security context in a xfrm_policy or xfrm_state from both relabelfrom and relabelto to setcontext.

It looks like the bridge netfilter code does not correctly update the hardware checksum after popping off the VLAN header. This is by inspection, I have *not* tested this.

When a user-space server application calls bind on a socket, then in kernel space this bound socket is considered 'x25-linked' and the SOCK_ZAPPED flag is unset.(As in x25_bind()/af_x25.c). Now when a user-space client application attempts to connect to the server on the listening socket, if the kernel accepts this in-coming call, then it returns a new socket to userland and attempts to reply to the caller. The reply/x25_sendmsg() will fail, because the new socket created on call-accept has its SOCK_ZAPPED flag set by x25_make_new(). (sock_init_data() called by x25_alloc_socket() called by x25_make_new() sets the flag to SOCK_ZAPPED)). Fix: Using the sock_copy_flag() routine available in sock.h fixes this. Tested on 32 and 64 bit kernels with x25 over tcp. Signed-off-by: NShaun Pereira <pereira.shaun@gmail.com> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NDavid S.

If the server decides to close the RPC socket, we currently don't actually respond until either another RPC call is scheduled, or until xprt_autoclose() gets called by the socket expiry timer (which may be up to 5 minutes later). This patch ensures that xprt_autoclose() is called much sooner if the server closes the socket. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

At some point, transport endpoint addresses will no longer be IPv4. To hide the structure of the rpc_xprt's address field from ULPs and port mappers, add an API for setting the port number during an RPC bind operation. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked. Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.

Add RPC client transport switch support for replacing buffer management on a per-transport basis. In the current IPv4 socket transport implementation, RPC buffers are allocated as needed for each RPC message that is sent. Some transport implementations may choose to use pre-allocated buffers for encoding, sending, receiving, and unmarshalling RPC messages, however. For transports capable of direct data placement, the buffers can be carved out of a pre-registered area of memory rather than from a slab cache. Test-plan: Millions of fsx operations. Performance characterization with "sio" and "iozone". Use oprofile and other tools to look for significant regression in CPU utilization.

Thanks to Ed Keizer for bug and root cause. He says: "... we could only mount the top-level Solaris share. We could not mount deeper into the tree. Investigation showed that Solaris allows UNIX authenticated FSINFO only on the top level of the share. This is a problem because we share/export our home directories one level higher than we mount them. I.e. we share the partition and not the individual home directories. This prevented access to home directories." We still may need to try auth_sys for the case where the client doesn't have appropriate credentials. Signed-off-by: NJ.
