In lnet_router_checker(), there are two LASSERTS. Neither protects us from anything and one of them triggered for a customer crashing the system unecessarily. This patch removes them. Signed-off-by:

lctl show_route and lctl route_list will output router aliveness information via lnet_get_route(). lnet_get_route() should use the lnet_is_route_alive() function, introduced in e8a1124 http://review.whamcloud.com/7857, to determine route aliveness. Signed-off-by:

This patch ensures that the correct number of router buffers are allocated. It keeps a count that keeps track of the number of buffers allocated. Another count keeps the number of buffers requested. The number of buffers allocated is set when creating new buffers and reduced when buffers are freed. The number of requested buffer is set when the buffers are allocated and is checked when credits are returned to determine whether the buffer should be freed or kept. In lnet_rtrpool_adjust_bufs() grab lnet_net_lock() before using rbp_nbuffers to ensure that it doesn't change by lnet_return_rx_credits_locked() during the process of allocating new buffers. All other access to rbp_nbuffers is already being protected by lnet_net_lock(). This avoids the case where we allocate less than the desired number of buffers. Signed-off-by:

On some platforms having sock.h in lib-types.h would collide with other included header files being used in the LNet layer. Looking at what was needed from sock.h only acceptor.c is dependent on it. To avoid these issues we just use sock.h only in acceptor.c. Signed-off-by:

When shutting down an NI in a busy system, some messages received on this NI, might be on the lazy portal. They would have grabbed a ref count on the NI. Therefore NI will not be removed until messages are processed. In order to avoid this scenario, when an NI is shutdown go through all messages queued on the lazy portal and drop messages for the NI being shutdown Signed-off-by:

There is a use case where lnet can be unloaded while there are no NIs configured. Removing lnet in this case will cause LNetFini() to be called without a prior call to LNetNIFini(). This will cause the LASSERT(the_lnet.ln_refcount == 0) to be triggered. To deal with this use case when LNet is configured a reference count on the module is taken using try_module_get(). This way LNet must be unconfigured before it could be removed; therefore avoiding the above case. When LNet is unconfigured module_put() is called to return the reference count. Signed-off-by:

This patch starts router checker thread all the time. The router checker only checks routes by ping if live_router_check_interval or dead_router_check_interval are set to something other than 0, and there are routes configured. If these conditions are not met the router checker sleeps until woken up when a route is added. It is also woken up whenever the RC is being stopped to ensure the thread doesn't hang. In the future when DLC starts configuring the live and dead router_check_interval parameters, then by manipulating them the router checker can be turned on and off by the user. Signed-off-by:

After adding a route, lnet_check_routes() is called to ensure that the route added doesn't invalidate the routing configuration. If lnet_check_routes() fails then the route just added, which caused the current configuration to be invalidated is deleted, and an error is returned to the user. Signed-off-by:

Currently if there exists a route that goes over a remote net and then this net is added dynamically as a local net, then traffic stops because the code in lnet_send() determines that the destination nid can be reached from another local_ni, but the src_nid is still stuck on the earlier NI, because the src_nid is stored in the ptlrpc layer and is not updated when a local NI is configured.

With DLC it's possible to start up a system with no NIs that require the acceptor thread, and thus it won't start. Later on the user can add an NI that requires the acceptor thread to start, it is then necessary to start it up. If the user removes a NI and as a result there are no more NIs that require the acceptor thread then it should be stopped. This patch adds logic in the dynamically adding and removing NIs code to ensure the above logic is implemented. Signed-off-by:

It is preferable to use NULL instead of 0 for pointers. This fixes sparse warnings such as: lustre/fld/fld_request.c:126:17: warning: Using plain integer as NULL pointer The second parameter of class_match_param() was changed to a const, to be able to remove a cast in one user, to prevent splitting a long line. No other code change. Signed-off-by:

Some functions and variables are only used in their C file, so reduce their scope. This reduces the code size, and fixes sparse warnings such as: warning: symbol 'proc_lnet_routes' was not declared. Should it be static? warning: symbol 'proc_lnet_routers' was not declared. Should it be static? Some prototypes were removed from C files and added to the proper header.

When adding route it ignored specific scenarios, namely: 1. route already exists 2. route is on a local net 3. route is unreacheable This patch returns the appropriate return codes from the lower level function lnet_add_route(), and then ignores the above case from the calling function, lnet_parse_route(). This is needed so we don't halt processing routes in the module parameters. However, we can now add routes dynamically, and it should be returned to the user whether adding the requested route succeeded or failed. In userspace it is determined whether to continue adding routes or to halt processing. Currently "lnetctl import < config" continues adding the rest of the configuration and reports at the end which operations passed and which ones failed. Signed-off-by:

This patch addresses a set of related issues: LU-5568, LU-5734, LU-5839, LU-5849, LU-5850. Create the local lnet_startup_lndni() API. This function starts up one LND. lnet_startup_lndnis() calls this function in a loop on every ni in the list passed in. lnet_startup_lndni() is responsible for cleaning up after itself in case of failure. It calls lnet_free_ni() if the ni fails to start. It calls lnet_shutdown_lndni() if it successfully called the lnd startup function, but fails later on. lnet_startup_lndnis() also cleans up after itself. If lnet_startup_lndni() fails then lnet_shutdown_lndnis() is called to clean up all nis that might have been started, and then free the rest of the nis on the list which have not been started yet. To facilitate the above changes lnet_dyn_del_ni() now manages the ping info. It calls lnet_shutdown_lndni(), to shutdown the NI. lnet_shutdown_lndni() is no longer an exposed API and doesn't manage the ping info, making it callable from lnet_startup_lndni() as well. There are two scenarios for calling lnet_startup_lndni() 1. from lnet_startup_lndnis() If lnet_startup_lndni() fails it requires to shutdown the ni without doing anything with the ping information as it hasn't been created yet. 2. from lnet_dyn_add_ni() As above it will shutdown the ni, and then lnet_dyn_add_ni() will take care of managing the ping info The second part of this change is to ensure that the LOLND is not added by lnet_parse_networks(), but the caller which needs to do it (IE: LNetNIInit) This change ensures that lnet_dyn_add_ni() need only check if there is only one net that's being added, if not then it frees everything, otherwise it proceeds to startup the requested net.

If there is an invalid networks or ip2nets lnet_parse_networks() gets called with a NULL 'network' string parameter lnet_parse_networks() needs to sanitize its input string now that it's being called from multiple places. Instead, check for a NULL string everytime the function is called, which reduces the probability of errors with other code modifications. Signed-off-by:

This is the fourth patch of a set of patches that enables DLC. This patch changes the IOCTL infrastructure in preparation of adding extra IOCTL communication between user and kernel space. The changes include: - adding a common header to be passed to ioctl infra functions instead of passing an exact structure. This header is meant to be included in all structures to be passed through that interface. The IOCTL handler casts this header to a particular type that it expects - All sanity testing on the past in structure is performed in the generic ioctl infrastructure code. - All ioctl handlers changed to take the header instead of a particular structure type Signed-off-by:
