2014-07-10prepare for upcoming ext4 read supportMartin Pelikan
Parts of the on-disk inode changed their meaning in order to support bigger sizes. More flags & prettification. No functional change. ok guenther

2014-05-27Zap a bunch of trailing whitespace.Kenneth R Westerback
2014-05-09disable IO_NOCACHE B_NOCACHE conversion until it works.Ted Unangst
2014-04-08add IO_NOCACHE flag to vop_write arguments, which in turn sets B_NOCACHEBob Beck
on the written buffers. Use the flag for writes from the page daemon to ensure that we free buffers written out by the page daemon rather than caching them. ok kettenis@
2014-01-25ufs_setattr() was assuming that the flag bits that indicatePhilip Guenther
atime/mtime/ctime need to be updated weren't already set. When they are, the code will end up treating the VNOVAL value from the VFS layer as a time_t. Port the fix from FreeBSD: the critical bit is to process the existing flag values before possibly setting them again in ufs_setattr(). This diff pulls in a larger change from FreeBSD to replace the macro ITIMES() with a function ufs_itimes() and to remove the atime and mtime arguments from ffs_update(): only ufs_setattr() used them so it makes more sense to just do the those bits directly there. tweaks and ok tedu@ matthew@
2013-12-12replace old bcopy/bzero with standard functions. ok kettenisTed Unangst
2013-12-01Change 'mountlist' from CIRCLEQ to TAILQ. Be paranoid andKenneth R Westerback
use TAILQ_*_SAFE more than might be needed. Bulk ports build by sthen@ showed nobody sticking their fingers so deep into the kernel. Feedback and suggestions from millert@. ok jsing@
2013-11-02No need to cast constants or simple variables to (daddr_t). UseKenneth R Westerback
(u_int64_t) instead of (daddr_t) when casting a variable in an expression passed to DL_SETDSIZE(). Change a variable counting open files from daddr_t to int64_t. ok deraadt@ with the tweak to fix that pesky expression.
2013-11-01Sprinkle (long long) casts where %lld is being used to print daddr_tKenneth R Westerback
variables. Some random whitespace/knf repairs encountered on the way. ok miod@ on inspection, feedback & more suggestions from millert@
2013-09-14Correct the handling of I/O of >=2^32 bytes and the ktracing there ofPhilip Guenther
by using size_t/ssize_t instead of int/u_int to handle I/O lengths in uiomove(), vn_fsizechk(), and ktrgenio(). Eliminate the always-zero 'error' argument to ktrgenio() at the same time.
2013-08-13Switch time_t, ino_t, clock_t, and struct kevent's ident and dataPhilip Guenther
members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@
2013-06-11final removal of daddr64_t. daddr_t has been 64 bit for a long enoughTheo de Raadt
test period; i think 3 years ago the last bugs fell out. ok otto beck others
2013-06-02TypoPhilip Guenther
2013-05-30UFS does't do inode numbers >2^32, so use a smaller type internally,Philip Guenther
only using ino_t in the VFS layer APIs: vget, readdir, getattr. otto wrote the original diff for libsa to keep bootblock from overflowing ok deraadt@ kettenis@
2013-04-15Add an f_mntfromspec member to struct statfs, which specifies the name ofJoel Sing
the special provided when the mount was requested. This may be the same as the special that was actually used for the mount (e.g. in the case of a device node) or it may be different (e.g. in the case of a DUID). Whilst here, change f_ctime to a 64 bit type and remove the pointless f_spare members. Compatibility goo courtesy of guenther@ ok krw@ millert@
2013-03-28Add support for _PC_TIMESTAMP_RESOLUTION for ffs/mfs, cd9600, ext2,Philip Guenther
msdos, NFS, fifos and devices, plus support for querying it in getconf(2) and the requisite pathconf(2) manpage blurb ok tedu@
2012-09-10Cleanup VFS mount string handling:Joel Sing
- Avoid using copyinstr() without checking the return value. - sys_mount() has already copied the path in, so pass this to the filesystem mount code so that it does not have to copy it in again. - Avoid copyinstr()/bzero() dance when we can simply bzero() and strlcpy(). ok krw@
2012-07-11If the current offset is strictly less than the process filesizePhilip Guenthe
rlimit, then a write that would take it over the limit should be clamped, making it a partial write. ok beck@
2012-03-23Make rusage totals, itimers, and profile settings per-process insteadPhilip Guenthe
of per-rthread. Handling of per-thread tick and runtime counters inspired by how FreeBSD does it. ok kettenis@

2011-07-04bread does nothing with its ucred argument. remove it. ok matthewTed Unangst
2011-07-04bread() takes daddr64_t block address, not int32_t, so use correct cast. ↵Kenneth R Westerback
bread() always takes DEV_BSIZE address units so don't bother getting the disklabel and trying to convert units to d_secsize. Nukes last references to d_secsize in ufs/. ok tedu@

2011-06-30Add DUID support for ext2fs mounts.Joel Sing
Initial diff from and tested by Luca Corti - thanks!
2011-04-05Every single vop_default is set to eopnotsupp, so retire itThordur I. Bjornsson
and return EOPNOTSUPP directly from the VOP_* functions. Filesystems should, at some point fill in every function in the vop_default struct so we can get rid of the 'if' statements in VOP_*.
2010-12-21Bring back the "End the VOP experiment." diff, naddy's issues whereThordur I. Bjornsson
unrelated, and his alpha is much happier now. OK deraadt@
2010-11-18Make sure readdir cookies are actually allocated with the correct sizeMiod Vallat
(in case eventually we change their type from u_long to something else), and do not truncate them to 32 bits in the ntfs code. ok tedu@
2010-09-23The only sensible argument for VOP_* calls that take a struct proc pointer isOwain Ainsworth
curproc. A bunch of callers were passing in 0 (not even NULL, 0) as this pointer, which was fine until the called vnode function tried to do something with it. Typically, this code was then copy/pasted to various parts of the tree. Accept the facts of life and switch all of these over to passing curproc for now until the argument can be removed. Discovered by stsp trying to create a softraid on top of a vnd, which crashed with a NULL deref in vndioctl. softraid bits tested by mikeb and jsing. raidframe bits tested by pea, matthieu and naddy. The rest tested by at least thib, jsing and myself. ok thib@, jsing@.
2010-09-23Change:Owain Ainsworth
/* something */ if (error) { VOP_UNLOCK(); return; } VOP_UNLOCK(); to the clearer and shorter: VOP_UNLOCK(); if (error) return; ok thib@, jsing@ as part of a larger diff.
2010-09-10Backout the VOP diff until the issues naddy was seeing on alpha (gcc3)Thordur I. Bjornsson
have been resolved.
2010-09-09Rename lookup/relookup to vfs_lookup/vfs_relookup.Thordur I. Bjornsson
OK oga@, beck@, matthew@
2010-09-06End the VOP experiment. Instead of the ridicolusly complicated operationThordur I. Bjornsson
vector setup that has questionable features (that have, as far as I can tell never been used in practice, atleast not in OpenBSD), remove all the gunk and favor a simple struct full of function pointers that get set directly by each of the filesystems. Removes gobs of ugly code and makes things simpler by a magnitude. The only downside of this is that we loose the vnoperate feature so the spec/fifo operations of the filesystems need to be kept in sync with specfs and fifofs, this is no big deal as the API it self is pretty static. Many thanks to armani@ who pulled an earlier version of this diff to current after c2k10 and Gabriel Kihlman on tech@ for testing. Liked by many. "come on, find your balls" deraadt@.

EFAULT when appropriate. ok deraadt@, miod@
2010-05-18dont let sys/ioctl.h imply that you get the ioctls in dkio.h. thisDavid Gwynne
gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include <sys/dkio.h> to the places that actually want and use the disk ioctls. this became an issue when krw@'s X build failed when he was testing a change to dkio.h. tested by krw@ help from and ok miod@

miod@ deraadt@ ok.
2009-09-05- don't try to shove a daddr64_t value into an int32_t.Jasper Lievisse Adriaanse
eventhough this won't really harm as ext2fs doesn't handle files that large, it was not correct. no objections from thib@
