* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2713-0/+26
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* firewire/sbp: try to improve locking, plus a few style nitsAndriy Gapon2017-03-071-23/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change tries to fix the most obvious locking problems. sbp_cam_scan_lun() is never called with the sbp lock held, so the lock needs to be acquired internally (if it's needed at all). Without this change a kernel with INVARIANTS panics when a firewire disk is connected: panic: mutex sbp not owned at /usr/src/sys/dev/firewire/sbp.c:967 KDB: stack backtrace: db_trace_self_wrapper() at 0xffffffff80420bbb = db_trace_self_wrapper+0x2b/frame 0xfffffe0504df0930 kdb_backtrace() at 0xffffffff80670359 = kdb_backtrace+0x39/frame 0xfffffe0504df09e0 vpanic() at 0xffffffff8063986c = vpanic+0x14c/frame 0xfffffe0504df0a20 panic() at 0xffffffff806395b3 = panic+0x43/frame 0xfffffe0504df0a80 __mtx_assert() at 0xffffffff8061c40d = __mtx_assert+0xed/frame 0xfffffe0504df0ac0 sbp_cam_scan_lun() at 0xffffffff80474667 = sbp_cam_scan_lun+0x37/frame 0xfffffe0504df0af0 xpt_done_process() at 0xffffffff802aacfa = xpt_done_process+0x2da/frame 0xfffffe0504df0b30 xpt_done_td() at 0xffffffff802ac2e5 = xpt_done_td+0xd5/frame 0xfffffe0504df0b80 fork_exit() at 0xffffffff805ff72f = fork_exit+0xdf/frame 0xfffffe0504df0bf0 fork_trampoline() at 0xffffffff8082483e = fork_trampoline+0xe/frame 0xfffffe0504df0bf0 --- trap 0, rip = 0, rsp = 0, rbp = 0 --- Also, I tried to reduce the scope of the sbp lock to avoid holding it while doing bus_dma allocations. The code badly needs some re-engineering. SBP really should implement a CAM transport, so that it avoids control flow inversion when re-scanning the bus. Also, the sbp lock seems to be too coarse. Additionally, the commit includes some changes not related to locking. - sbp_cam_scan_lun: restore CAM_DEV_QFREEZE before re-queueing the ccb because xpt_setup_ccb resets ccb_h.flags - sbp_post_busreset: call xpt_release_simq only if it's actually frozen - don't place private SIMQ_FREEZED flag (sic, "freezed") into sim->flags, use sbp->flags for that - some style fixes and control flow enhancements Reviewed by: sbruno MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D9898 Notes: svn path=/head/; revision=314864

* Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)Alan Somers2017-01-042-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are fixed-length strings. AFAICT the only place they're read is in sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated. However, the kernel doesn't null-terminate them. A bunch of copy-pasted code uses strncpy to write them, and doesn't guarantee null-termination. For at least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually overflows. You can see the result by doing "camcontrol negotiate da0 -v". This change null-terminates those fields everywhere they're set in the kernel. It also shortens a few strings to ensure they'll fit within the 16-character field.

* fwohci: report whether PhysicalUpperBound register is implementedAndriy Gapon2016-11-241-0/+10
| | | | | | | | | | | | | | | | | Please see section 5.15 of 1394 OHCI Specification. If the register is not implemented, then the physical response unit is limited to the first 4GB of the physical memory. In that case the non-cooperative debugging over firewire (using /dev/fwmem) can not be expected to work if a target has more RAM than that. The method is described in gdb.4 and the Developer's Handbook. It seems that most of the consumer hardware does not implement PhysicalUpperBound register.

* Prevent overflow issues in timeout processingSteven Hartland2014-11-211-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | Previously, any timeout value for which (timeout * hz) will overflow the signed integer, will give weird results, since callout(9) routines will convert negative values of ticks to '1'. For unsigned integer overflow we will get sufficiently smaller timeout values than expected. Switch from callout_reset, which requires conversion to int based ticks to callout_reset_sbt to avoid this. Also correct isci to correctly resolve ccb timeout. This was based on the original work done by Eygene Ryabinkin <rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid the overlow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

* Set target->sbp field to valid value when sbp device is created.Alexander Kabaev2014-06-201-1/+1
| | | | | | | | | | | | | | | The sbp_cam_detach_target can be called from sbp_post_explore function on the first target that is not really attached and it was written with the corresponding safety check in place to tolerate that. Unfortunately the recent locking cleanup did add a locking assertion that tries to dereference the target->sbp pointer unconditionally, which causes less than desirable outcome. Since the assertion is useful, just initialize the target sbp pointer once when sbp device is being initialized instead of when the target is being attached. This makes assertion work in all cases and fixes the crash on boot. Notes: svn path=/head/; revision=267660

* Update the CAM API for FreeBSD 10:Scott Long2013-09-241-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | - Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0; MPSAFE drivers should be managing their own timeout storage. The remaining non-MPSAFE drivers have been modified to also manage their own storage, and should be considered for updating to MPSAFE (or removal) during the FreeBSD 10.x lifecycle. - Add fields related to soft timeouts and quality of service, to be used in upcoming work. - Add room for more flags in the CCB header and path_inq structures. - Begin support for extended 64-bit LUNs. - Bump the CAM version number to 0x18, but add compat shims. Tested with camcontrol and smartctl. Reviewed by: nathanw, ken, kib Approved by: re Obtained from: Netflix Notes: svn path=/head/; revision=255853

* Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCIScott Long2013-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

| | | | | | | | | | | Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph". If at some point we need some real XPT periphs (alike to pmpX now), quite likely they will be per-bus, and not a single global instance as xpt_periph now. Notes: svn path=/head/; revision=249468
