* iscsi: Fetch limits based on a socket rather than assuming global limits.John Baldwin2022-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | cxgbei needs the ability to return different limits based on the connection (e.g. if the connection is over a T5 adapter or a T6 adapter as well as factoring in the MTU). This change plumbs through the changes in the ioctls without changing any of the backends. The limits callback passed to icl_register now accepts a second socket argument which holds the integer file descriptor. To support ABI compatiblity for old binaries, the callback should return "global" values if the socket fd is zero. The CTL_ISCSI_LIMITS argument used with CTL_ISCSI by ctld(8) now accepts the socket fd in a field that was previously part of a reserved spare field. Old binaries zero this request which results in passing a socket fd of 0 to the limits callback. The ISCSIDREQUEST ioctl no longer returns limits. Instead, iscsid(8) invokes a new ISCSIDLIMITS ioctl after establishing the connection via connect(2). For ABI compat, if the old ISCSIDREQUEST is invoked, the global limits are still fetched (with a socket fd of 0) and returned.

* iscsi: Handle unmapped I/O requests.John Baldwin2022-03-101-0/+24
| | | | | | | | | | | | | | | | | | Don't assume that csio->data_ptr is pointer to a data buffer that can be passed to icl_get_pdu_data and icl_append_data. For unmapped I/O requests, csio->data_ptr is instead a pointer to a struct bio as indicated by CAM_DATA_BIO. To support these requests, add icl_pdu_append_bio and icl_pdu_get_bio methods which pass a pointer to the bio and an offset and length relative to the bio's buffer. Note that only backends supporting unmapped requests need to implement these hooks. Implement simple no-op hooks for the iser backend.

* ibcore: Declare ib_post_send() and ib_post_recv() arguments constHans Petter Selasky2021-07-122-6/+10
| | | | | | | | | | | | | | | | | | | Since neither ib_post_send() nor ib_post_recv() modify the data structure their second argument points at, declare that argument const. This change makes it necessary to declare the 'bad_wr' argument const too and also to modify all ULPs that call ib_post_send(), ib_post_recv() or ib_post_srq_recv(). This patch does not change any functionality but makes it possible for the compiler to verify whether the ib_post_(send|recv|srq_recv) really do not modify the posted work request.

* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-1/+2
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE.

* Make the iSCSI parameter negotiation more flexible.Navdeep Parhar2016-08-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | Decouple the send and receive limits on the amount of data in a single iSCSI PDU. MaxRecvDataSegmentLength is declarative, not negotiated, and is direction-specific so there is no reason for both ends to limit themselves to the same min(initiator, target) value in both directions. Allow iSCSI drivers to report their send, receive, first burst, and max burst limits explicitly instead of using hardcoded values or trying to derive all of them from the receive limit (which was the only limit reported by the drivers prior to this change). Display the send and receive limits separately in the userspace iSCSI utilities.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in ICL interface. - the ordering of parameters to icl_conn_task_setup is different, so that the "cookie" is last. - the icl_conn_connected() method is gone, replaced by much simpler mechanism. I'd rather keep the ICL interface as small as possible. - I don't really like the s/offload/driver/g. The "tcp" is not a driver; "iser" is not really a driver either. I'd prefer to leave it as it is. - the check for ic_session_type_discovery() in iser_conn_handoff() is gone, as handoff cannot happen for discovery sessions. - ic_session_login_phase() and ic_session_type_discovery() are gone. If you had your handoff method called - you're no longer in either of those. - the way maxtags is passed is different; now it's simply ic->ic_maxtags. It's cleaner, and the old way would cause weird things to happen if fail_on_disconnection=1 and the user changed the maxtags sysctl before reconnecting (basically the CAM idea of maxtags would be different from iSER one). - icl_hba_misc() is gone; declare support for PIM_UNMAPPED by setting ic->ic_unmapped flag. - the way we find the "iser" ICL module is rewritten - we have a flag for icl_register() that says if the module is iSER-capable or not. - icl_conn_release() is gone; iser_conn_release() is called from iser_conn_free() (no functional change in this case) and at the beginning of icl_conn_connect(), to handle reconnection.

It's not connected to the build just yet; it still needs some tweaks to adapt to my changes to iSCSI infrastructure. Big thanks to Mellanox for their support for FreeBSD!
