| * i2c: Convert most new-style drivers to use module aliasingJean Delvare2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

| * i2c: Add support for device alias namesJean Delvare2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported.

| * i2c/tps65010: Add missing intialization of client dataJean Delvare2008-04-29
| | | | | | | | | | | | | | | | | | | | | | tps65010_remove() calls i2c_get_clientdata(client) but the client data is never set during initialization, so it gets a NULL pointer at best. I guess it was never spotted because the tps65010 driver is typically not built modular so this function is discarded.

| * | IB/mthca: Avoid changing userspace ABI to handle DMA write barrier attributeRoland Dreier2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit cb9fbc5c ("IB: expand ib_umem_get() prototype") changed the mthca userspace ABI to provide a way for userspace to indicate which memory regions need the DMA write barrier attribute. However, it is possible to handle this without breaking existing userspace, by having the mthca kernel driver recognize whether it is talking to old or new userspace, depending on the size of the register MR structure passed in. The only potential drawback of this is that is allows old userspace (which has a bug with DMA ordering on large SGI Altix systems) to continue to run on new kernels, but the advantage of allowing old userspace to continue to work on unaffected systems seems to outweigh this, and we can print a warning to push people to upgrade their userspace.

| * | IB/mthca: Avoid recycling old FMR R_Keys too soonOlaf Kirch2008-04-29

This poses a problem for RDS, which uses ib_fmr_unmap as a fence operation. RDS assumes that after issuing an unmap, the old R_Keys will be invalid for a "reasonable" period of time. For instance, Oracle processes uses shared memory buffers allocated from a pool of buffers. When a process dies, we want to reclaim these buffers -- but we must make sure there are no pending RDMA operations to/from those buffers. The only way to achieve that is by using unmap and sync the TPT. However, when the sequence count is reset on unmap, there is a high likelihood that a new mapping will be given the same R_Key that was issued a few milliseconds ago. To prevent this, don't reset the sequence count when unmapping a FMR. Signed-off-by: Olaf Kirch <olaf.kirch@oracle.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | IB/ehca: Allocate event queue size depending on max number of CQs and QPsStefan Roscher2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a lot of QPs fall into Error state at once and the EQ of the respective HCA is too small, it might overrun, causing the eHCA driver to stop processing completion events and calling the application's completion handlers, effectively causing traffic to stop.

| * | RDMA/cxgb3: Support peer-2-peer connection setupSteve Wise2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Open MPI, Intel MPI and other applications don't respect the iWARP requirement that the client (active) side of the connection send the first RDMA message. This class of application connection setup is called peer-to-peer. Typically once the connection is setup, _both_ sides want to send data. This patch enables supporting peer-to-peer over the chelsio RNIC by enforcing this iWARP requirement in the driver itself as part of RDMA connection setup. Connection setup is extended, when the peer2peer module option is 1, such that the MPA initiator will send a 0B Read (the RTR) just after connection setup. The MPA responder will suspend SQ processing until the RTR message is received and reply-to. In the longer term, this will be handled in a standardized way by enhancing the MPA negotiation so peers can indicate whether they want/need the RTR and what type of RTR (0B read, 0B write, or 0B send) should be sent. This will be done by standardizing a few bits of the private data in order to negotiate all this. However this patch enables peer-to-peer applications now and allows most of the required firmware and driver changes to be done and tested now. Design: - Add a module option, peer2peer, to enable this mode. - New firmware support for peer-to-peer mode: - a new bit in the rdma_init WR to tell it to do peer-2-peer and what form of RTR message to send or expect. - process _all_ preposted recvs before moving the connection into rdma mode. - passive side: defer completing the rdma_init WR until all pre-posted recvs are processed. Suspend SQ processing until the RTR is received. - active side: expect and process the 0B read WR on offload TX queue. Defer completing the rdma_init WR until all pre-posted recvs are processed. Suspend SQ processing until the 0B read WR is processed from the offload TX queue. - If peer2peer is set, driver posts 0B read request on offload TX queue just after posting the rdma_init WR to the offload TX queue. - Add CQ poll logic to ignore unsolicitied read responses.

Fix these by: - serializing abort reply and peer abort processing with disconnect processing - warning (and ignoring) if ep timer is stopped when it wasn't running - cleaning up disconnect path to correctly deal with aborting and dead endpoints - in iwch_modify_qp(), taking a ref on the ep before releasing the qp lock if iwch_ep_disconnect() will be called.

With this patch, TTY input auditing is controlled from user-space only. On the other hand, not even for daemons does it make sense to audit "input" from PTY masters; this data was produced by a program writing to the PTY slave, and does not represent data entered by the user.

| | | | | | | | | | | | | | | | | | Key lengths were arbitrarily limited to 32 characters. If userspace is going to start using the single kernel key field as multiple virtual key fields (example key=key1,key2,key3,key4) we should give them enough room to work.

| * Audit: standardize string audit interfacesEric Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch standardized the string auditing interfaces. No userspace changes will be visible and this is all just cleanup and consistancy work. We have the following string audit interfaces to use: void audit_log_n_hex(struct audit_buffer *ab, const unsigned char *buf, size_t len); void audit_log_n_string(struct audit_buffer *ab, const char *buf, size_t n); void audit_log_string(struct audit_buffer *ab, const char *buf); void audit_log_n_untrustedstring(struct audit_buffer *ab, const char *string, size_t n); void audit_log_untrustedstring(struct audit_buffer *ab, const char *string); This may be the first step to possibly fixing some of the issues that people have with the string output from the kernel audit system. But we still don't have an agreed upon solution to that problem. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * Audit: stop deadlock from signals under loadEric Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A deadlock is possible between kauditd and auditd under load if auditd receives a signal. When auditd receives a signal it sends a netlink message to the kernel asking for information about the sender of the signal. In that same context the audit system will attempt to send a netlink message back to the userspace auditd. If kauditd has already filled the socket buffer (see netlink_attachskb()) auditd will now put itself to sleep waiting for room to send the message. Since auditd is responsible for draining that socket we have a deadlock. The fix, since the response from the kernel does not need to be synchronous is to send the signal information back to auditd in a separate thread. And thus auditd can continue to drain the audit queue normally. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * Audit: save audit_backlog_limit audit messages in case auditd comes backEric Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch causes the kernel audit subsystem to store up to audit_backlog_limit messages for use by auditd if it ever appears sometime in the future in userspace. This is useful to collect audit messages during bootup and even when auditd is stopped. This is NOT a reliable mechanism, it does not ever call audit_panic, nor should it. audit_log_lost()/audit_panic() are called during the normal delivery mechanism. The messages are still sent to printk/syslog as usual and if too many messages appear to be queued they will be silently discarded. I liked doing it by default, but this patch only uses the queue in question if it was booted with audit=1 or if the kernel was built enabling audit by default.

| * Audit: collect sessionid in netlink messagesEric Paris2008-04-28
| | | | | | | | | | | | | | | | | | | | Previously I added sessionid output to all audit messages where it was available but we still didn't know the sessionid of the sender of netlink messages. This patch adds that information to netlink messages so we can audit who sent netlink messages. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
