| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Bad performance may result because *all* polled sockets contend for this single lock.

* | RDS: Fix congestion issues for loopbackAndy Grover2010-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have two kinds of loopback: software (via loop transport) and hardware (via IB). sw is used for 127.0.0.1, and doesn't support rdma ops. hw is used for sends to local device IPs, and supports rdma. Both are used in different cases. For both of these, when there is a congestion map update, we want to call rds_cong_map_updated() but not actually send anything -- since loopback local and foreign congestion maps point to the same spot, they're already in sync. The old code never called sw loop's xmit_cong_map(),so rds_cong_map_updated() wasn't being called for it. sw loop ports would not work right with the congestion monitor. Fixing that meant that hw loopback now would send congestion maps to itself. This is also undesirable (racy), so we check for this case in the ib-specific xmit code.

| * RDMA/cm: fix loopback address supportSean Hefty2009-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RDMA CM is intended to support the use of a loopback address when establishing a connection; however, the behavior of the CM when loopback addresses are used is confusing and does not always work, depending on whether loopback was specified by the server, the client, or both. The defined behavior of rdma_bind_addr is to associate an RDMA device with an rdma_cm_id, as long as the user specified a non- zero address. (ie they weren't just trying to reserve a port) Currently, if the loopback address is passed to rdam_bind_addr, no device is associated with the rdma_cm_id. Fix this. If a loopback address is specified by the client as the destination address for a connection, it will fail to establish a connection. This is true even if the server is listing across all addresses or on the loopback address itself. The issue is that the server tries to translate the IP address carried in the REQ message to a local net_device address, which fails. The translation is not needed in this case, since the REQ carries the actual HW address that should be used. Finally, cleanup loopback support to be more transport neutral. Replace separate calls to get/set the sgid and dgid from the device address to a single call that behaves correctly depending on the format of the device address. And support both IPv4 and IPv6 address formats.

| * percpu: use DEFINE_PER_CPU_SHARED_ALIGNED()Tejun Heo2009-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few places where ___cacheline_aligned* is used with DEFINE_PER_CPU(). Use DEFINE_PER_CPU_SHARED_ALIGNED() instead. DEFINE_PER_CPU_SHARED_ALIGNED() applies alignment only on SMPs. While all other converted places used _in_smp variant or only get compiled for SMP, net/rds used unconditional ____cacheline_aligned. I don't see any reason these data structures should be aligned on UP and thus converted together.

* | RDS: Add a debug message suggesting to load transport modulesAndy Grover2009-08-23
| | | | | | | | | | | | | | | | | | Now that RDS transports are no longer compiled-in to RDS core, there is now the possibility that they will not be loaded. This adds a helpful suggestion when rds_bind() fails to find a transport. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | RDS: Track transports via an array, not a listAndy Grover2009-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that transports can be loaded in arbitrary order, it is important for rds_trans_get_preferred() to look for them in a particular order, instead of walking the list until it finds a transport that works for a given address. Now, each transport registers for a specific transport slot, and these are ordered so that preferred transports come first, and then if they are not loaded, other transports are queried.

* | RDS: Modularize RDMA and TCP transportsAndy Grover2009-08-23
| | | | | | | | | | | | | | | | | | | | | | Enable the building of transports as modules. Also, improve consistency of Kconfig messages in relation to other protocols, and move build dependency on IB from the RDS core code to the rds_rdma module.

* | RDS: Export symbols from core RDSAndy Grover2009-08-23
| | | | | | | | | | | | | | | | Now that rdma and tcp transports will be modularized, we need to export a number of functions so they can call them. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | RDS: Add TCP transport to RDSAndy Grover2009-08-23
| | | | | | | | | | | | | | | | | | | | | | This code allows RDS to be tunneled over a TCP connection. RDMA operations are disabled when using TCP transport, but this frees RDS from the IB/RDMA stack dependency, and allows it to be used with standard Ethernet adapters, or in a VM.

Also the values of PF_INET and AF_INET are the same. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ struct sockaddr_in sip; @@ ( sip.sin_family == - PF_INET + AF_INET | sip.sin_family != - PF_INET + AF_INET | sip.sin_family = - PF_INET + AF_INET ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
