* + add u_long sector_size to struct disk (documented in libdisk.3)jkh2001-05-131-15/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | + make Open_Disk sense the sector size by trying 512, 1024 and 2048 in this order. This makes the kernel note that dscheck(cd1): bio_bcount 512 is not on a sector boundary (ssize 2048) dscheck(cd1): bio_bcount 1024 is not on a sector boundary (ssize 2048) if 2048 is the sector size. If this worries anyone: the message is from /usr/src/sys/kern/subr_diskslice.c and shutups are to be placed there. + Have read_block and write_block use an additional parameter, the sector size. + replace all barfout calls with return NULL, 0, __LINE__, etc. Note that this does NOT emit diagnostics. More often than not, you don't want library functions to scribble on stderr -- it may not even be available. The right thing is to propagate the error condition to upper management. The app should take care of errors. + use d1->sector_size instead of 512 in various places. I've left many places untouched, especially those writing MBRs. I simply added another arg hardcoded as 512. This is because I would not know what I'm doing... I felt this approach would be reasonably backward compatible and not introduce any new bugs in critical software. Famous last words. Messing with MBRs might soon put me in the same screwup meister category as, uh, never mind. :-) + bump the max no of disks from 20 to 32 (due to PR 24503).

* Libraries should _never_ call exit() themselves (or its alternate spellingobrien2001-03-181-0/+8
| | | | | | | | | | | `err()'). libdisk does! and additionally libdisk gets confused on Alpha disks with foreign disklabels, throws up its hands and exits. This is the cause of the "going no where without my init" install bug on the Alpha. So now on the Alpha, rather than call err(), we print the error string and continue processing. Submitted by: jkh

| | | | | | Set_Boot_Blocks() anyway and should thus have never been a part of libdisk, it should have been provided by the client of libdisk since passing the information in is already part of the API.

* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-1/+1
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

* Make libdisk C++ aware:joerg1996-03-241-108/+113
| | | | | | | - add __BEGIN_DECLS and __END_DECLS, - add a bunch of ``const'' qualifiers all over the place, - rename the `private' struct member into `private_data' to avoid the clash with the C++ keyword.

* Make the target for tst01 more sensible.phk1995-05-031-1/+3
| | | | | | | | | | | | | Remove bogus targets. Allocate partition letters as follows: lowest offset "flags & CHUNK_IS_ROOT" gets 'a', lowest offset "subtype==FS_SWAP" gets 'b' the rest is allocated in offset order from this sequence "defghab". This will generally make sense. Added rules to complain if more than one CHUNK_IS_ROOT or more than one FS_SWAP per FreeBSD chunk. Set CHUNK_IS_ROOT on the 'a' partition in Open_Disk. Run Fixup_Names in Open_Disk.

* Next Iteration, getting better.phk1995-04-291-2/+7
| | | | | | | | Made an All_FreeBSD() function. Added a cmd-line interface (lowest rank) to the tst01 program. The tst01 program is harmless (worst it can do is coredump), but it is instructive to run, you can see what the slice-code things of your disk...
