2016-01-13Implement VFS read clustering for MSDOSFS.Martin Pieuchot
The logic used in msdosfs_bmap() to loop calling pcbmap() comes from FreeBSD and is not really efficient but it is good enough since it is only called when generating I/O. With this diff I get a 100% improvement when reading big files from a crappy USB stick. With this and bread_cluster(9) modified to not re-fetch B_CACHED buffers, reading large contiguous files with chunk sizes of MAXPHYS is almost as fast as physio(9) on the same device. For a 'real world' example, when copying music files from a USB stick I see a speed jump from 15MB/s on -current to 24Mb/s with this diff. While here rename some 'lbn' variables into 'cn' to better reflect what we're dealing with. Tested by Mathieu, with support from deraadt@
2015-10-23Fix renaming in the root directory by correctly setting directoryKenneth R Westerback
offset. From Serguey Parkhomovsky via bugs@, in response to problem report from matthieu@. Same fix is in NetBSD for one. ok tedu@
2015-10-23Fix printf() types so kernel compiles with or w/o MSDOSFS_DEBUG.Kenneth R Westerback
e.g. print pointers with %p instead of %08x. No changes outside of MSDOSFS_DEBUG.
2015-10-23Nuke a bunch of leading/embedded/trailing whitespace so the code can beKenneth R Westerback
read without generating spurious headaches.
2015-09-23remove lockmgr_printinfo stubs. from Martin NatanoTed Unangst
2015-04-17Tweaks utimensat/futimens handling to always update ctime, even when bothPhilip Guenther
atime and mtime are UTIME_OMIT (at least for ufs, tmpfs, and ext2fs), and to correctly handle a timestamp of -1. ok millert@
2015-03-14Remove some includes include-what-you-use claims don'tJonathan Gray
have any direct symbols used. Tested for indirect use by compiling amd64/i386/sparc64 kernels. ok tedu@ deraadt@
2015-02-13Include sys/stdint.h for SIZE_MAX instead of relying on the misplacedTodd C. Miller
define in sys/limits.h. OK guenther@
2015-02-10First step towards making uiomove() take a size_t size argument:Miod Vallat
- rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

2014-12-16primary change: move uvm_vnode out of vnode, keeping only a pointer.Ted Unangst
objective: vnode.h doesn't include uvm_extern.h anymore. followup changes: include uvm_extern.h or lock.h where necessary. ok and help from deraadt

2014-06-18Fix off by one in pm_inusemap.Tobias Stoeckmann
FreeBSD did this years ago in revision 126086 as pointed out by John-Mark Gurney on tech. Merge it and sync two occurrences. ok krw@
2014-05-27Fix 'mount -ur' for msdosfsStefan Fritsch

2014-05-09stop using B_AGE, it was effectively retired some time ago.Ted Unangst
2014-05-09disable IO_NOCACHE B_NOCACHE conversion until it works.Ted Unangst
2014-04-21msdosfs timestamps can only represent 1/1/1980 throughKenneth R Westerback
12/31/2107. 64-bit time_t now dominates that entire range, so simply set all dates that cannot be represented to 1/1/1980 like Redmond intended. Problem reported by Alessandro De Laurenzis via misc@. ok guenther@
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@
2013-12-24fix error checking oddity in msdosfs code, as noted by kettenis@Alexander Hall

2013-12-14Zero out dirent structures that will be copied out to avoid leaking garbagePhilip Guenther
in the padding or trailing name bytes. ok beck@ millert@ espie@
2013-10-01Format string fixes: %hu/%hd for uint16_t, %u/%d/%x for uint32_tStefan Fritsch
- despite the name, ntohl returns uint32_t, not long - also fix some %d into %u
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
2013-05-23revoke's default imp works.Marc Espie
okay tedu@
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@
2013-03-28Handle the pathconf _PC_PATH_MAX, _PC_PIPE_BUF, _PC_ASYNC_IO,Philip Guenther
_PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're fs-independent for us. Since we don't support latter three on any fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO symbols in <unistd.h> (via sys/unistd.h) with value -1. Also, zap pointless tty-only values from procfs(!). ok beck@, deraadt@
2013-01-15Make the FAT setattr handling more consistent about unsupportedMartynas Venckus
attributes; making it more "user-friendly". Mostly from FreeBSD. OK guenther@, krw@.
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@
2012-09-06Remove the need to occasionally treat dos file names as strings byKenneth R Westerback
using "%.11s" to print them out. Make all dos file names 11 byte arrays and nuke the attempt to put '\0' at the 12th position of such an array. Fixes 'panic: smashed stack in msdosfs_rename.c' reported by MERHIGI Marcus via tech@. Tested by MERHIGI Marcus. Suggestions and ok tedu@.
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@
2012-06-20Cleanup our filesystem pathconf() code a little bit to make it easierMatthew Dempsky
to diff against FreeBSD's. From Brad; no object file change on amd64.
2012-04-05As it was made evident by Olaf 'Rhialto' Seibert in the NetBSD PR 34583,Mike Belopuhov
caching the last cluster in the file before extending it considerably speeds up further lookups. As a consequence this keeps write speed from gradually decreasing and provides a measurable (up to 2x) performance increase. Prompted by the diff from Alexander Polakov, ok miod, krw.

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@
