- Add `no' keyword, which can be used in the following ways:
no file-system SOMEFS
no makeoptions FOO
no options OPT1[,OPT2[,...]]
no pseudo-device somepseudo
This turns off a previous file-system/makeoptions/options/pseudo-device
entry for the same item.
Grammar support for 'no device DEV at ATTACH' added, but not
implemented yet.
Code changes:
- Convert many simple lists to TAILQs
- Convert prefix to SLIST
- Remove argument names from prototypes.
- Don't bother with custom alloc code for hashtables; just use emalloc()
like everything else.
- Implement ht_remove(), to remove an entry from a hash table.
Add removed entries to a freelist for later reuse.
- Don't selectbase() devices and pseudo-devices at definition time; instead
do it at one pass after the config file has been parsed in fixdevis().
- Rename nvhead to nvfreelist; a more apt name...
- Minor code cleanups.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
bbinfo.c module; news* boot blocks occupy all of the first 16 sectors,
with a jump instruction to skip the label at bytes 64..511.
Replace news_clearboot() and news_setboot() callbacks with common
news_copydisklable() callback, and set bbinfo_params->offset to
NEWS_BOOT_BLOCK_OFFSET (which is now 0), and ->headeroffset to 0.
(Thanks to Izumi for picking this up; the perils of working on code at 2am)
- bbinfo_params:
- replace "int littleendian" with "bbinfo_endian endian"
- add comments
- shared_bbinfo_clearboot():
- add callback method to shared_bbinfo_clearboot()
- don't clear from 0..headeroffset; use a callback to do that
- add news68k and newsmips support.
From Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>, with a rework by me to
take advantage of the new shared_bbinfo_clearboot() callback.
(XXX: untested yet)
column gets a trailing "," if there's more entries to come.
- if getmachines() or getfstypes() is called with 3 NULL params, just
print the list of supported items.
- in usage(), call getmachines() and getfstypes() with 3 NULL params.
(i got sick of typing "installboot -m asdf" to get a list of
supported machines during testing :)
- unify sparc_bbinfo (1064 bytes, with 256 block entries)
and sun68k_bbinfo (296 byte, with 64 block entries)
into shared_bbinfo (512 bytes, with 118 block entries),
which will be also shared by future bbinfo-using platforms
(including macppc)
- add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs
bootxx version skew.
- add macppc support
*/bootxx.c:
- migrate to new shared_bbinfo structure
installboot:
- add macppc support (still needs applepartmap support and testing)
- improve and add some more warnings & errors to installboot
- implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which
perform the majority of the work for bbinfo-using back-ends
(rather than replicating that across multiple back-ends).

and use instead of replicating the effort in various locations
- if filesystem is not a regular file, use sync(2) instead of fsync(2)
after the bootstrap has been written
- move <sys/stat.h> and <stdint.h> into "installboot.h"
and use instead of replicating the effort in various locations
- if filesystem is not a regular file, use sync(2) instead of fsync(2)
after the bootstrap has been written
- add `-B s2bno', to provide the starting block for the secondary bootstrap.
intended for use on platforms where the blocks of the stage2 bootstrap
are hardcoded into the stage1 bootstrap (currently: sparc, sun2)
- don't support `-b s1bno' for sparc or sun2, since the primary is always
at a fixed location on the disk.
- if `filesystem' is a regular file, use fsync(2) instead of sync(2)
code changes:
- add hardcode_stage2(), which uses -B s2bno and the size of the
provided secondary bootstrap (as an actual file, not as part of the
`filesystem' argument) to provide a sequential list of blocks from s2bno,
each block being the appropriate file system size (from
params->fstype->blocksize)
- add blocksize and needswap run-time parameters to ib_fs
- in *_match(), set params->fstype->blocksize to the underlying block size
(8KB for raw), and params->fstype->needswap as appropriate
- rename IB_STARTBLOCK to IB_STAGE1START, and add IB_STAGE2START
- use hardcode_stage2() to implement raw_findstage2() and IB_STAGE2BLOCK
support for ffs_findstage2()
- improve some comments, add some prototypes, ...
based on some code from Todd C. Miller, which in turn was based on a
patch from Brian Poole <raj@cerias.purdue.edu>.
Look first in any uid ranges specified on the command line, in the order
they were given on the command line, and then in any ranges specified in
the defaults file.
With thanks to Brian for nudging me a number of times to fix this.
UID ranges. Previous behaviour is demonstrated below...
# useradd -D
group users
base_dir /home
skel_dir /etc/skel
shell /bin/csh
class
inactive 0
expire Null (unset)
range 10200..10300
# useradd -D -r 10200..10300 -r 10400..10500
# useradd -D
group users
base_dir /home
skel_dir /etc/skel
shell /bin/csh
class
inactive 0
expire Null (unset)
range 10400..10500
The second command should have put 2 ranges back into the config file,
but it really only put one because the first range on the command line
was marked as a duplicate (but when it got to writing the config file,
it only wrote command line ranges, so the 10200 got skipped). Fix
this by initializing defrc to 0 and then only looking after defrc for
duplicate ranges.
+ if the cd built-in fails, don't try to copy the directory hierarchy
with pax - s/;/&&/ in a shell command
+ clean up after ourselves if a rename fails - remove the newly-created
group file.
file descriptor leak fix.
null encryption algorithm key length fix (should use 0).
couple of null-pointer reference fixes.
set port # to 500 in ID payload (possible interop issue - spec is unclear).
correctly match address pair on informational exchange
execution. CRON_TZ sets the time zone within which a job is
considered for execution (but not in which it runs), and CRON_WITHIN
allows jobs to be skipped whose execution is delayed for any reason
(eg, the system was sleeping or the load average is too high for
timely execution).
make -V FILES
from being useful (and given that every other variable can be
extracted using make -V, the behaviour was unusually inconsistent
given that the original reason for clearing it doesn't seem to be
relevant anymore)
- use <bsd.prog.mk> instead of directly including <bsd.files.mk>
(and possibly <bsd.man.mk> or <bsd.own.mk>)
- remove obsolete NOPROG
fstype checking, and back-end "ffs" support.
- Consistently use at least uint32_t for blocknumbers (vs. int / long / ...)
- Consistently use uintXX_t instead of u_intXX_t.
- Move various duplicated prototypes into "installboot.h"
existing backends, but future ones need it)
- use "bootstrap" instead of "boot block" in various messages where appropriate
- rename some members of ib_params
to use when they don't support a particular method
- don't automatically generate machines.c anymore
- add entries for i386 (temporarily unsupported) and shark
(permanently unsupported)
