* Turn on serialization of task management commands going down to theken2010-10-071-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | controller, but make it optional. After a problem report from Andrew Boyer, it looks like the LSI chip may have issues (the watchdog timer fired) if too many aborts are sent down to the chip at the same time. We know that task management commands are serialized, and although the manual doesn't say it, it may be a good idea to just send one at a time. But, since I'm not certain that this is necessary, add a tunable and sysctl variable (hw.mps.%d.allow_multiple_tm_cmds) to control the driver's behavior. mps.c: Add support for the sysctl and tunable, and add a comment about the possible return values to mps_map_command(). mps_sas.c: Run all task management commands through two new routines, mpssas_issue_tm_request() and mpssas_complete_tm_request(). This allows us to optionally serialize task management commands. Also, change things so that the response to a task management command always comes back through the callback. (Before it could come via the callback or the return value.) mpsvar.h: Add softc variables for the list of active task management commands, the number of active commands, and whether we should allow multiple active task management commands. Add an active command flag. mps.4: Describe the new sysctl/loader tunable variable. Sponsored by: Spectra Logic Corporation
* Check the device name validity on device registration.jh2010-10-071-7/+16
| | | | | | | | | | | | | | | | A new function prep_devname() sanitizes a device name by removing leading and redundant sequential slashes. The function returns an error for names which already exist or are considered invalid. A new flag MAKEDEV_CHECKNAME for make_dev_p(9) and make_dev_credf(9) indicates that the caller is prepared to handle an error related to the device name. An invalid name triggers a panic if the flag is not specified. Document the MAKEDEV_CHECKNAME flag in the make_dev(9) manual page. Idea from: kib Reviewed by: kib

* Split $ipv6_prefer into $ip6addrctl_policy and $ipv6_activate_all_interfaces.hrs2010-09-131-24/+64
| | | | | | | | | | | | | | | | | | | The $ip6addrctl_policy is a variable to choose a pre-defined address selection policy set by ip6addrctl(8). The keyword "ipv4_prefer" sets IPv4-preferred one described in Section 10.3, the keyword "ipv6_prefer" sets IPv6-preferred one in Section 2.1 in RFC 3484, respectively. When "AUTO" is specified, it attempts to read /etc/ip6addrctl.conf first. If it is found, it reads and installs it as a policy table. If not, either of the two pre-defined policy tables is chosen automatically according to $ipv6_activate_all_interfaces. When $ipv6_activate_all_interfaces=NO, interfaces which have no corresponding $ifconfig_IF_ipv6 is marked as IFDISABLED for security reason. The default values are ip6addrctl_policy=AUTO and ipv6_activate_all_interfaces=NO. Discussed with: ume and bz

| | | | | | | | | | | | | | | | | called when the sbuf internal buffer is filled. For kernel sbufs with a drain, the internal buffer will never be expanded. For userland sbufs with a drain, the internal buffer may still be expanded by sbuf_[v]printf(3). Sbufs now have three basic uses: 1) static string manipulation. Overflow is marked. 2) dynamic string manipulation. Overflow triggers string growth. 3) drained string manipulation. Overflow triggers draining. In all cases the manipulation is 'safe' in that overflow is detected and managed. Reviewed by: phk (the previous version)
