perseant 83adb24145 Allow negative values other than UNASSIGNED to be returned from ufs_bmap; 
fixes a bug introduced in the 64-bit daddr_t conversion, that manifests
itself in LFS with kernels compiled with the FFS_EI option.

pk 338f31f581 Make the buffer cache code MP-safe. 2003-02-05 21:38:38 +00:00
perseant 14c17e57b4 Don't call a dirop within a dirop: if lfs_rename is actually deleting 
a link, call lfs_remove directly before starting dirop rather than
having ufs_rename do it.

tron f1eeaa9020 Only use MALLOC_DECLARE() in kernel namespace. 2003-02-01 18:34:14 +00:00
thorpej b193480908 Add extensible malloc types, adapted from FreeBSD. This turns 
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

yamt 84d61a1dc4 there's no need to treat VOP_WHITEOUT as dirop 
because it modifies only one inode.
 2003-01-30 14:18:32 +00:00
yamt 53d6eb47ee don't use daddr_t for segment summary since it's an on-disk structure. 2003-01-29 13:14:33 +00:00
simonb 0adecbd12b Remove variable that is only assigned to but not referenced. 2003-01-29 03:06:40 +00:00
yamt e41d3a6f1c make these compilable with lfs debug options. 
(follow daddr_t change)

XXX maybe segment number should be 64bit.
 2003-01-27 23:17:56 +00:00
kleink 865868a8b1 Further printf format fixes in the wake of daddr_t. 
Note that PRI?64 and long long int arguments aren't made for each other,
nor are %lld and int64_t arguments.
 2003-01-27 21:45:52 +00:00
tsutsui daf84696c6 More printf format cleanup to reduce casts. 2003-01-26 06:42:31 +00:00
kleink 4e0e5333ae Fix further printf format warnings for DEBUG, in the wake of daddr_t 
having changed.
 2003-01-25 23:00:09 +00:00
tron 5067836b9e Use PRId64 instead of hard coding "%lld" to fix build problems under 
LP64 ports.
 2003-01-25 18:12:31 +00:00
fvdl a138610cac The oldblks and newblks arrays are used to store direct copies of 
on-disk block pointers, so they should be int32_t. Error found
by Izumi Tsutsui.
 2003-01-25 16:40:28 +00:00
tron 63dda858c6 Fix printf() format strings problems caused by "daddr_t" change. 2003-01-25 12:50:38 +00:00
fvdl a3ff3a3038 Bump daddr_t to 64 bits. Replace it with int32_t in all places where 
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.

thorpej b78f59b443 Merge the nathanw_sa branch. 2003-01-18 08:51:40 +00:00
yamt 03e1a46833 - zerofill struct lfs when allocating it. 
- use M_ZERO instead of memset after malloc.
 2003-01-12 13:04:52 +00:00
yamt 5f254d46cc backout wrong assertions that i added. 2003-01-08 17:16:52 +00:00
yamt 99d625b53c for lfs_remove/lfs_rmdir, keep removed vnodes marked VDIROP. 
(backout parts of rev.1.40)
otherwise, directory structures can be corrupted because checkpoints can
occur via eg. lfs_vflush before parent directory is written.
 2003-01-08 17:14:58 +00:00
yamt 69f1c0cb29 in set_dirop/endop, use normal vref/vrele instead of lfs versions 
so that we don't miss lfs_inactivate.
 2003-01-08 15:43:29 +00:00
yamt ee36fccabb add assertions. 2003-01-08 15:40:54 +00:00
yamt 49d2b56b43 use lfs_unmark_vnode instead of duplicated code fragments. 2003-01-08 15:40:04 +00:00
wiz 1035faff1d writable, not writeable. 2003-01-06 20:30:28 +00:00
chs 822a8f2c0f several bugs: 
- move calls to softdep_setup_pagecache() (which can sleep to allocate
   memory) outside the softdep lock.
 - replace the softdep_flush_indir() hack (which tries to find another
   vnode to fsync when we are holding lots of buffer-cache buffers locked
   for long periods of time) with softdep_trackbufs() (which just kicks
   the syncer and sleeps under the same circumstances).  the former method
   had a lock-ordering problem which would occasionally deadlock.
 - relax the assertion in softdep_sync_metadata() which says that we should
   never see D_ALLOCDIRECT deps for VREG vnodes.  it's ok to see those
   attached to indirect blocks.

also, there's no need to splbio() while allocating the buffer headers
to which pagecache dependencies are attached, so remove that.

fixes all the problems in PR 19288.
 2003-01-01 23:08:56 +00:00
yamt a5bf83bbfc don't set vnode type to VNON in error case of ufs_makeinode. 
(backout rev.1.74)

it seems that there's no need to do it (anymore?) and LFS has trouble with it.
(VNON vnodes marked VDIROP will never reclaimed)

ok'ed by Frank van der Linden.

yamt 140a8e56ca write ifile only when it has dirty buffers. 2002-12-31 14:54:32 +00:00
yamt cb9613feef comment and assertions 2002-12-30 05:34:17 +00:00
yamt 6fc496c67a move check of lfs_unlockvp from lfs_reserveavail to lfs_reserve 
because lfs_reservebuf needs same check as well.
 2002-12-30 05:31:53 +00:00
yamt a05fbf74c0 fix vref/vunref mismatch. 2002-12-29 14:08:12 +00:00
yamt 88ae33f9e0 backout assertions in lfs_inactive. 
they can be false when unmounting forcibly.
 2002-12-29 07:05:55 +00:00
christos ae2bf40b7e fix compile problem. 2002-12-28 20:08:36 +00:00
yamt d840722863 avoid warnings without DIAGNOSTIC. 
pointed by Andreas Wrede.
 2002-12-28 17:22:47 +00:00
yamt a428d8a5af dirop inode can't be passed to lfs_inactivate. 2002-12-28 15:12:26 +00:00
yamt 59be5399b7 - in lfs_reserve, vref vnodes that we're locking so that cleaner doesn't 
try to reclaim them.
  (workaround for deadlock noted in the comment in lfs_reserveavail)
- in lfs_rename, mark vnodes which are being moved as well as directry vnodes.
 2002-12-28 14:39:08 +00:00
hannken c122326822 Clear IN_SPACECOUNTED on (re-)used inodes. 
This cures the "unmount pending error:" on softdep umounts.

Approved by: Frank van der Linden <fvdl@netbsd.org>
 2002-12-27 16:07:13 +00:00
yamt 4b9c604ba7 - in lfs_reserve, reserve locked buffer count as well. 
- don't wait for locking buf in lfs_bwrite_ext to avoid deadlocks.
- skip lfs_reserve when we're doing dirop.
  reserve more (for lfs_truncate) in set_dirop instead.

this mostly solves PR 18972. (and hopefully PR 19196)
 2002-12-26 13:37:18 +00:00
yamt e9bd1836a5 don't try to write all blocks passed to lfs_markv at once 
since it likely causes buf starvation.
 2002-12-26 13:04:39 +00:00
yamt 362c57a2d2 add a XXX comment. (description of possible deadlock) 2002-12-22 17:31:52 +00:00
yamt 4370be165c add a XXX comment 2002-12-21 05:35:54 +00:00
yamt 0d95cc5d66 correct/add assertion. 2002-12-18 14:05:50 +00:00
yamt beff0dd387 #if 0 out vnode unlock/lock in lfs_reserve for now and add a comment about it. 
deadlock is better than corruption (or panic), IMO.
 2002-12-17 15:23:37 +00:00
yamt a999523301 no need for cleaner to hold vnode locks. 
cleaner and normal vnode operations are synchronized enough by
seglock/fraglock and buf's B_BUSY-ness.
 2002-12-17 14:37:49 +00:00
yamt b2d5b49e2b use ufs_daddr_t instead of int where appropriate. 2002-12-17 14:28:54 +00:00
yamt a79cb6db43 - in lfs_bwrite_ext, if we're cleaner, 
mark inode IN_CLEANING rather then IN_MODIFIED.
  otherwise cleaned (indirect) blocks belongs to the inode isn't written
  until next sync.
- add assertions.
 2002-12-14 13:41:25 +00:00
yamt e5ea55e4ea in lfs_writefile, check v_type==VNON earlier. 
to avoid null dereference with DEBUG_LFS_VERBOSE.
 2002-12-14 11:54:47 +00:00
yamt 8fe8a4ced8 save a segment write when doing checkpoint. 2002-12-13 14:40:02 +00:00
yamt 275b3a47a2 correct DIAGNOSTIC code for duplicated inodes in a segment and su_nbytes. 2002-12-12 12:28:13 +00:00
yamt 9097ffce96 take care of B_CLRBUF in lfs_balloc. 
otherwise you'll see uninitialized blocks.
 2002-12-11 13:34:14 +00:00
matt 60db16d1ff Add multiple inclusion protection for headers. Fix mismatched 
variable declarations (missing const's) as needed.
