| | | | | | | | | | | | | | | | Add new mlx5ib(4) driver to the kernel source tree which supports Remote DMA over Converged Ethernet, RoCE, for the ConnectX-4 series of PCI express network cards. There is currently no user-space support and this driver only supports kernel side non-routable RoCE V1. The krping kernel module can be used to test this driver. Full user-space support including RoCE V2 will be added as part of the ongoing upgrade to ibcore from Linux 4.9. Otherwise this driver is feature equivalent to mlx4ib(4). The mlx5ib(4) kernel module will only be built when WITH_OFED=YES is specified. Approved by: re (marius) Sponsored by: Mellanox Technologies

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r279992 (by ian): Add a new flag, SBUF_INCLUDENUL, and new get/set/clear functions for flags. The SBUF_INCLUDENUL flag causes the nulterm byte at the end of the string to be counted in the length of the data. If copying the data using the sbuf_data() and sbuf_len() functions, or if writing it automatically with a drain function, the net effect is that the nulterm byte is copied along with the rest of the data. r280149 (by ian): Update an sbuf assertion to allow for the new SBUF_INCLUDENUL flag. If INCLUDENUL is set and sbuf_finish() has been called, the length has been incremented to count the nulterm byte, and in that case current length is allowed to be equal to buffer size, otherwise it must be less than. Add a predicate macro to test for SBUF_INCLUDENUL, and use it in tests, to be consistant with the style in the rest of this file. r280193 (by ian): The minimum sbuf buffer size is 2 bytes (a byte plus a nulterm), assert that. Values smaller than two lead to strange asserts that have nothing to do with the actual problem (in the case of size=0), or to writing beyond the end of the allocated buffer in sbuf_finish() (in the case of size=1). r288223 (by cem): sbuf: Process more than one char at a time Revamp sbuf_put_byte() to sbuf_put_bytes() in the obvious fashion and fixup callers.

The former is the standard header, and allows us to compile libsbuf on macOS/linux. r314397 (by scottl): Implement sbuf_prf(), which takes an sbuf and outputs it to stdout in the non-kernel case and to the console+log in the kernel case. For the kernel case it hooks the putbuf() machinery underneath printf(9) so that the buffer is written completely atomically and without a copy into another temporary buffer. This is useful for fixing compound console/log messages that become broken and interleaved when multiple threads are competing for the console. r314399 (by scottl): Add prototype for sbuf_putbuf() r314419 (by jkim): Include stdio.h to fix libsbuf build. r314420 (by scottl): Provide a comment on why stdio.h needs to be included. r314533 (by scottl): Expose the sbuf_putbuf() symbol to libsbuf. There are a few other symbols that are present but not exposed, like get/set/clear flags, not sure if they need to be exposed at this point. r316553: sbuf(3): expose sbuf_{clear,get,set}_flags(3) via libsbuf These functions were added to sbuf(9) in r279992, but never exposed to userspace. Expose them now so they can be used/tested.

Previously, this was set to the last valid target ID. -Don't exclude target IDs of RAID components or check for a reuse of a target ID for RAID components. -Some endienness was added.

After FreeBSD SVN revision 236814, the pass(4) driver changed from only doing error recovery when the CAM_PASS_ERR_RECOVER flag was set on a CCB to sometimes doing error recovery if the passed in retry count was non-zero. Error recovery would happen if two conditions were met: 1. The error recovery action was simply a retry. (Which is most cases.) 2. The retry_count is non-zero. (Which happened a lot because of cut-and-pasted code.) This explains a bug I noticed in with camcontrol: # camcontrol tur da34 -v Unit is ready # camcontrol reset da34 Reset of 1:172:0 was successful At this point, there should be a Unit Attention: # camcontrol tur da34 -v Unit is ready No Unit Attention. Try it again: # camcontrol reset da34 Reset of 1:172:0 was successful Now set the retry_count to 0 for the TUR: # camcontrol tur da34 -v -C 0 Unit is not ready (pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00 (pass42:mps1:0:172:0): CAM status: SCSI Status Error (pass42:mps1:0:172:0): SCSI status: Check Condition (pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred) (pass42:mps1:0:172:0): Field Replaceable Unit: 2 There is the unit attention. camcontrol(8) has a default retry_count of 1, in case someone sets the -E flag without setting -C. The CAM_PASS_ERR_RECOVER behavior was only broken with the CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has worked as intended (error recovery is only done when the flag is set) in the asynchronous API (CAMIOQUEUE ioctl). sys/cam/scsi/scsi_pass.c: In passsendccb(), when calling cam_periph_runccb(), only specify the error routine when CAM_PASS_ERR_RECOVER is set. share/man/man4/pass.4: Document that CAM_PASS_ERR_RECOVER is needed to enable error recovery.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add basic programmable early warning error injection to the sa(4) driver. This will help application developers simulate end of tape conditions. To inject an error in sa0: sysctl kern.cam.sa.0.inject_eom=1 This will return the next read or write request queued with 0 bytes written. Any subsequent writes or reads will go along as usual. This will also cause the early warning position flag to get set for the next position query. So, 'mt status' will show the BPEW (Beyond Programmable Early Warning) flag on the first query after an error injection. After that, the position flags will be as they are in the underlying tape drive. Also, update the sa(4) man page to describe tape parameters, which can be set via 'mt param'. sys/cam/scsi/scsi_sa.c: In saregister(), create the inject_eom sysctl variable. In sastart(), check to see whether inject_eom is set. If so, return the read or write with 0 bytes written to indicate EOM. Set the set_pews_status flag so that we fake PEWS status in the next position call for reads, and the next 3 calls for writes. This allows the user to see the BPEW flag one time via 'mt status'. In sagetpos(), check the set_pews_status flag and fake PEWS status and decrement the counter if it is set. share/man/man4/sa.4: Document the inject_eom sysctl variable. Document all of the parameters currently supported via 'mt param'. usr.bin/mt/mt.1: Point the user to the sa(4) man page for more details on supported parameters. Sponsored by: Spectra Logic
