* Fix setdumpdev():David Greenman1995-05-292-32/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - the major number wasn't checked, so accesses beyond the end of bdevsw[] were possible. Bogus major numbers are easy to get because `sysctl -w' doesn't handle dev_t's reasonably - it doesn't convert names to dev_t's and it converts the number 1025 to the dev_t 0x35323031. - Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV (the interface is too braindamaged to say which). -1 was interpreted as a size and resulted in the bogus error ENOSPC. - it was possible to set the dumpdev for devices without a d_psize() function. This is equivalent to setting the dumpdev to NODEV except it confuses sysctl. - change a 512 to DEV_BSIZE. There is an official macro dtoc() for converting "pages" to disk blocks but it is never used in /usr/src/sys. There is much confusion between PAGE_SIZE sized pages and NBPG sized pages. Maxmem consists of both. Not fixed: - there is nothing to invalidate the dumpdev if the media goes away. This reduces the benefits of the early calculation of dumplo. Bounds checking in the dump routines is relied on to reduce the risk of damage and little would be lost by relying on the dump routines to calculate dumplo. - no attempt is made to stay away from the start of the device to avoid clobbering labels. Fix wrong && anachronistic comment about the type of bootdev. Reviewed by: davidg Submitted by: Bruce Evans Notes: svn path=/head/; revision=8833

* Changes to fix the following bugs:David Greenman1995-05-2111-106/+325
| | | | | | | | | | | | | | | | | | 1) Files weren't properly synced on filesystems other than UFS. In some cases, this lead to lost data. Most likely would be noticed on NFS. The fix is to make the VM page sync/object_clean general rather than in each filesystem. 2) Mixing regular and mmaped file I/O on NFS was very broken. It caused chunks of files to end up as zeroes rather than the intended contents. The fix was to fix several race conditions and to kludge up the "b_dirtyoff" and "b_dirtyend" that NFS relies upon - paying attention to page modifications that occurred via the mmapping.

These changes fix the behavior to conform to the behavior in SunOS, which is to deny faults to pages beyond the EOF (returning SIGBUS).

* Fixes to the aic7xxx sequencer code and device driver from Justin Gibbs:David Greenman1995-05-173-60/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) If a target initiated a sync negotiation with us and happened to chose a value above 15, the old code inadvertantly truncated it with an "& 0x0f". If the periferal picked something really bad like 0x32, you'd end up with an offset of 2 which would hang the drive since it didn't expect to ever get something so low. We now do a MIN(maxoffset, given_offset). 2) In the case of Wide cards, we were turning on sync transfers after a sucessfull wide negotiation. Now we leave the offset alone in the per target scratch space (which implies asyncronous transfers since we initialize it that way) until a syncronous negotation occurs. 3) We were advertizing a max offset of 15 instead of 8 for wide devices. 4) If the upper level SCSI code sent down a "SCSI_RESET", it would hang the system because we would end up sending a null command to the sequencer. Now we handle SCSI_RESET correctly by having the sequencer interrupt us when it is about to fill the message buffer so that we can fill it in ourselves. The sequencer will also "simulate" a command complete for these "message only" SCBs so that the kernel driver can finish up properly. The cdplay utility will send a "SCSI_REST" to the cdplayer if you use the reset command. 5) The code that handles SCSIINTs was broken in that if more than one type of error was true at once, we'd do outbs without the card being paused. The else clause after the busfree case was also an accident waiting to happen. I've now turned this into an if, else if, else type of thing, since in most cases when we handle one type of error, it should be okay to ignore the rest (ie if we have a SELTO, who cares if there was a parity error on the transaction?), but the section should really be rewritten after 2.0.5. This fix was the least obtrusive way to patch the problem. 6) Only tag either SDTR or WDTR negotiation on an SCB. The real problem is that I don't account for the case when an SCB that is tagged to do a particular type of negotiation completes or SELTOs (selection timeout) without the negotiation taking place, so the accounting of sdtrpending and wdtrpending gets screwed up. In the wide case, if we tag it to do both wdtr and sdtr, it only performs wdtr (since wdtr must occur first and we spread out the negotiation over two commands) so we always have sdtrpending set for that target and we never do a real SDTR. I fill properly fix the accounting after 2.0.5 goes out the door, but this works (as confirmed by Dan) on wide targets. Other stuff that is also included: 1) Don't do a bzero when recycling SCBs. The only thing that must explicitly be set to zero is the scb control byte which is done in ahc_get_scb. We also need to set the SG_list_pointer and SG_list_count to 0 for commands that do not transfer data. 2) Mask the interrupt type printout for the aic7870 case. The bit we were using to determine interrupt type is only valid for the aic7770. Submitted by: Justin Gibbs Notes: svn path=/head/; revision=8567

The driver was actually setting the length to 6+6+2+50 (64 bytes), which when adding in the CRC (which is automatically appended to the frame and not included in the length), the minimum frame is 4 bytes larger than it is supposed to be. All of this is confirmed by tcpdump showing 50 bytes of data for minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This analysis has also revealed that there is garbage in the un-filled in portion at the end of the minimum frames from the 'ed' driver; I don't plan to fix this.

There is a performance/resource win available by getting the NSWAPDEV right (but only if you have just one swap-device ??), but using that as default would be too restrictive.
