yamt 12ee5f9c3a nfs_namei: return EACCES for empty filenames as rfc1813 says. 2005-01-28 10:12:23 +00:00
yamt 2520660990 nfs_clearcommit: don't attempt to clear commit info (n_pushlo, etc)
unless the vnode is of VREG.  union members used to keep commit info
are used for other purposes in the case of !VREG.

yamt f1661c75d1 - simplify nfs_bio.c rev.1.126

yamt cf56f2b873 keep directory eof cache when inactivating vnode
because there's no reason to throw it away.
(fix an unintended side effect of nfs_subs.c rev.1.144.)
2005-01-27 11:33:26 +00:00
yamt 407a63dc34 nfs_bioread:
- if a buffer is still empty after successful nfs_doio, it implies EOF.
- don't cache blocks beyond EOF.

yamt f6e331ee7c nfs_readdirrpc, nfs_readdirplusrpc:

yamt de3e729ad9 s/time/mono_time/ for n_attrstamp and n_accstamp. (parts of) PR/25641. 2005-01-21 14:31:29 +00:00
yamt fc08656a20 implement inaccurate mtime/ctime detection.
namely, if mtime or ctime are same between pre_op_attr and post_op_attr
when we expected them to be changed, don't trust the server.

chs 8975a0856f adjust the UBC mapping code to support non-vnode uvm_objects.
this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway.  there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.
2005-01-09 16:42:43 +00:00
yamt e5bd47dc3c invalidate cache if filesize is changed besides our activity
because it means that we're out of sync with the server.
2005-01-09 01:32:32 +00:00
yamt 68c071389c nfs_lookup: check n_nctime for positive entries as well to improve
cache consistency.

yamt ee344f939f redirect some VOPs which shouldn't be used for nfs
to genfs_badop (ie. panic).
2004-12-14 09:15:23 +00:00
yamt e3ed5def47 - centerize code to invalidate stale cache.
- don't ignore errors when invalidating buffers in nfs_open.

bouyer 0f82537ed4 The macro used for static server address is NFS_BOOTSTATIC_SERVADDR, not
NFS_BOOTSTATIC_SADDR. From Xen source distribution.
XXX NFS_BOOTSTATIC* doesn't seem to be documented anywhere ...

yamt 8cd5f554ba nfsrv_commit: make cnt unsigned so that very large commit requests can be
handled properly.
2004-12-09 02:18:45 +00:00
yamt 2bc7120ab8 when calling create-type VOP, make sure that va_mode is set
even when a client doesn't specify it.
(most filesystems get confused if va_mode is VNOVAL.)
2004-12-09 01:48:22 +00:00
yamt f11ea18093 nfsrv_read: fall back to copying when fail to loan pages.
(i forgot to commit this with uvm_loan.c rev.1.51.)
2004-12-04 08:07:52 +00:00
yamt a9fa9f0745 since daddr_t is 64-bit these days, simply use nfs directory cookies
as buffer cache indexes.  regress/sys/fs/getdents is now supposed to work.
fix PR/27112.

yamt 4fd5a025bf nfs_request: a workaround for servers doing "maproot".
for i/o requests which are expected not to fail due to permission
to mimic unix file open semantics (READ, WRITE, COMMIT),
try two credentials.  namely, the file owner's one and open time one.
remember which credential worked in per-file basis and try it first
next time to minimize number of retries.
ideas from Chuck Silvers.  PR/23716 and PR/24987.

yamt bee0b74932 remove a "proc botch" debug printf. ok'ed by Jonathan Stone. 2004-08-18 23:44:47 +00:00
mycroft 45a21b76f0 Fixing age old cruft:
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
  d_type fields(!), add a new internal flag, IMNT_DTYPE.

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

Sync some bug fixes from FFS into ext2fs, particularly:
* ffs_lookup.c 1.21, 1.28, 1.33, 1.48
* ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67
* ffs_vnops.c 1.84, 1.85, 1.86

Clean up some crappy pointer frobnication.

yamt 7653f67dd6 nfs_readdirplusrpc: fix a very long-standing cache corruption bug.
in the case of !bigenough, don't fill d_type or dnlc with bogus data.
2004-07-20 22:02:21 +00:00
yamt 62190652f1 revert nfs_vnops.c rev.1.189.
it's no longer needed because cache_enter() has been changed to handle
duplicated entries by itsself.

yamt e9bca9a46e nfs_doio_read: on short read, zero out the rest of the buffer unconditionally.
we can't rely on n_size here because it can be changed under us.

yamt 1c77f27a7a nfs_commit: use NAC_NOTRUNC when loading an attribute

yamt 72afe94686 nfs_fsinfo: when changing rsize/wsize,
keep mnt_fs_bshift in-sync.  otherwise genfs_getpages behaves badly.

yamt 0f5d997ee9 - include opt_inet.h for INET.
- catchup to in_ifaddr -> in_ifaddrhead rename.

XXX the address on the top of in_ifaddrhead is likely 127.0.0.1.
using it to construct the verifier doesn't make much sense.
maybe it's better to use some uuid or ip_randomid-like method.
2004-07-08 11:21:35 +00:00
yamt fad58613ba nfs_create: after an exclusive create rpc, make sure to update

yamt 21ae434eb2 nfs_lookup: use cache_lookup_raw() so that:
- "intrusive" dirops now have more chances to get benefits from dnlc.
- fixes a deadlock due to vnode locking order inversion.

nfs_create and others: purge stale dnlc entries
as nfs_lookup() no longer does it automatically.
