* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [PATCH] knfsd: allow the server to provide a gid list when using AUTH_UNIX ↵NeilBrown2007-02-14
| | | | | | | | | | | | | | | | | authentication AUTH_UNIX authentication (the standard with NFS) has a limit of 16 groups ids. This causes problems for people in more than 16 groups. So allow the server to map a uid into a list of group ids based on local knowledge rather depending on the (possibly truncated) list from the client. If there is no process on the server responding to upcalls, the gidlist in the request will still be used.

* [PATCH] knfsd: add some new fsid typesNeilBrown2007-02-14
| | | | | | | | | | | | | | | | | Add support for using a filesystem UUID to identify and export point in the filehandle. For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up too much room. For NFSv3+, we use the full 16 bytes, and possibly also a 64bit inode number for exports beneath the root of a filesystem. When generating an fsid to return in 'stat' information, use the UUID (hashed down to size) if it is available and a small 'fsid' was not specifically provided.

This allows us to simplify the fsid selection code. Also change "ref_fh_version" and "ref_fh_fsid_type" to "version" and "fsid_type", as the important thing isn't that they are the version/type of the reference filehandle, but they are the chosen type for the new filehandle.

* [PATCH] knfsd: fix return value for writes to some files in 'nfsd' filesystemNeilBrown2007-02-14
| | | | | | | | | | | | | | | Most files in the 'nfsd' filesystem are transactional. When you write, a reply is generated that can be read back only on the same 'file'. If the reply has zero length, the 'write' will incorrectly return a value of '0' instead of the length that was written. This causes 'rpc.nfsd' to give an annoying warning. This patch fixes the test.

* [PATCH] 8250 UART backup timerAlex Williamson2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch below works around a minor bug found in the UART of the remote management card used in many HP ia64 and parisc servers (aka the Diva UARTs). The problem is that the UART does not reassert the THRE interrupt if it has been previously cleared and the IIR THRI bit is re-enabled. This can produce a very annoying failure mode when used as a serial console, allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it into working again (ie. an unattended reboot could stall). To solve this problem, a backup timer is introduced that runs alongside the standard interrupt driven mechanism. This timer wakes up periodically, checks for a hang condition and gets characters moving again. This backup mechanism is only enabled if the UART is detected as having this problem, so systems without these UARTs will have no additional overhead. This version of the patch incorporates previous comments from Pavel and removes races in the bug detection code. The test is now done before the irq linking to prevent races with interrupt handler clearing the THRE interrupt. Short delays and syncs are also added to ensure the device is able to update register state before the result is tested. Aristeu says: this was tested on the following HP machines and solved the problem: rx2600, rx2620, rx1600 and rx1620s. hpa says: I have seen this same bug in soft UART IP from "a major vendor."

* [PATCH] ia64: fix noncoherent DMA API so devres buildsRoland Dreier2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | On ia64, drivers/base/dma-mapping.c doesn't build because it calls dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be terminally broken; the calls end up generating errors like drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release': drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent' because the multiple levels of macro expansion in <asm/dma-mapping.h> and <asm/machvec.h> end up turning a call to dma_free_noncoherent() into ia64_mv.platform_dma_free_coherent (instead of the intended ia64_mv.dma_free_coherent).

This works since the device will never write MTTs on mem-free HCAs, once we get rid of the use of the WRITE_MTT firmware command. This change is needed to make that work, and is an improvement for now, since it gives FMRs a chance at working. For MPTs, both the device and CPU might write there, so we must allocate DMA coherent memory for these. Signed-off-by: Michael S.

The idea is to increase performance by increasing the MTU from the maximum of 2K (theoretically 4K) supported by IPoIB on top of UD. With this code, I'm able to get 800MByte/sec or more with netperf without options on a Mellanox 4x back-to-back DDR system. Some notes on code: 1. SRQ is used for scalability to large cluster sizes 2. Only RC connections are used (UC does not support SRQ now) 3. Retry count is set to 0 since spec draft warns against retries 4. Each connection is used for data transfers in only 1 direction, so each connection is either active(TX) or passive (RX). 2 sides that want to communicate create 2 connections. 5. Each active (TX) connection has a separate CQ for send completions - this keeps the code simple without CQ resize and other tricks 6. To detect stale passive side connections (where the remote side is down), we keep an LRU list of passive connections (updated once per second per connection) and destroy a connection after it has been unused for several seconds. The LRU rule makes it possible to avoid scanning connections that have recently been active. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
