* kfifo: fix warn_unused_resultStefani Seibold2009-12-221-2/+3
| | | | | | | | | | | | | | | | | | | Fix the "ignoring return value of '...', declared with attribute warn_unused_result" compiler warning in several users of the new kfifo API. It removes the __must_check attribute from kfifo_in() and kfifo_in_locked() which must not necessary performed. Fix the allocation bug in the nozomi driver file, by moving out the kfifo_alloc from the interrupt handler into the probe function. Fix the kfifo_out() and kfifo_out_locked() users to handle a unexpected end of fifo.

| | | | | | | | | | | | | | | Move the pointer to the spinlock out of struct kfifo.

* kfifo: move struct kfifo in placeStefani Seibold2009-12-222-35/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new generic kernel FIFO implementation. The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.

The problem started on the passive side, which generated an STtag that was 0. The passive side sent a TERMINATE instead of an MPA REJECT msg. The active side, receives TERMINATE and sends connect_err() and set the cm_node state to CLOSED. The passive side sends FIN + ACK after TERMINATE. Active side ends up in handle_ack_pkt() and send_reset(). send_reset() consumes 1 cm_node's ref_count. Because the cm_node is in CLOSED state, which means that cm_node will be destroyed after completion of the connect_err() indication, CM will crash after send_reset().

Here is the sequence of what happened: (1) In MVAPICH2, connect request is received for port #0. FIX: Add a nes_connect() check to make sure local or remote tcp port is not 0. (2) Remote node's (passive) TCP stack sends a reset when it gets a connect request because of port = 0. Active side set the connect error to IW_CM_EVENT_STATUS_REJECTED when it received the RST from remote node. FIX: The corect error code is -ECONNRESET. (3) Wrong error code of IW_CM_EVENT_STATUS_REJECTED causes the core to destroy its listener ports. Here there are connections that may have sent an MPA request up and waiting for accept or reject. But the listener and its cm_nodes have been freed already causing the crash noticed. FIX: The cm_node is freed only if its state is not NES_CM_STATE_MPAREQ_RCVD. If cm_node's state is NES_CM_STATE_MPAREQ_RCVD then its new state is set to NES_CM_STATE_LISTENER_DESTROYED and it is not freed. When nes_accept() or nes_reject() is received, its state is checked for NES_CM_STATE_LISTENER_DESTROYED and in this case the cm_node is freed and error is returned.

To fix this, make sure that no interrupts are running by killing the interrupt tasklet. Also lock the shca_list_lock to protect against the poll_eqs_timer running concurrently.

I tried hard to understand what it might protect, but finally gave up. Roland noted that qlogic seems to have abandoned the ipath driver and came to the following wise conclusion: "So I guess if the BKL stuff is blocking you in any way, we can just drop it from ipath and leave it as yet another race condition in a rotting old driver."
