2016-09-15all pools have their ipl set via pool_setipl, so fold it into pool_init.David Gwynne
the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);
2016-09-10Add a noperm mount flag for FFS to be used for building release setsMartin Natano
without root privileges. This is only the kernel/mount flag; additional work in the build Makefile's will be necessary such that the files in $DESTDIR are created with correct permissions. tedu couldn't find anything wrong with it in a quick review idea & ok deraadt

2016-05-23Use arc4random_uniform() instead of arc4random() to avoid modulus bias.Theo Buehler
This eliminates the idiom 'arc4random() % X' (where X + 1 is not a power of two) from base. Part of a patch from Matthew Martin from end of last year. ok tedu@ (a long time ago), natano@

2016-05-22When pulling an msdos formated umass stick during mount while theAlexander Bluhm
usb stack was busy, the kernel could trigger an uvm fault. There is a race between vop_generic_revoke() and sys_mount() where vgonel() could reset v_specinfo. Then v_specmountpoint is no longer valid. So after sleeping, msdosfs_mountfs() could crash in the error path. The code in the different *_mountfs() functions was inconsistent, implement the same check everywhere. OK krw@ natano@
2016-05-10FFS2 does lazy inode initialization, so try harder to avoid usingKenneth R Westerback
random data on the disk as an inode. Thus avoiding crashes when translating a bogus filehandle to a vnode. Yes, I'm looking at you, NFS! Adapted from a diff by Christos Zoulas via NetBSD, pointed out by kurt@. ok beck@
2016-04-27Pad struct ext2fs out to 1024 (a.k.a. ext2fs SBSIZE) bytes. SatisfiesKenneth R Westerback
assumptions in fsck_ext2fs and eliminates spurious "VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE" messages. Part of the problem reported to bugs@ by Lampshade. ok beck@
2016-04-26Populate all necessary statfs members in .vfs_statfs. cd9660, udf,Martin Natano
msdosfs and nfsv2 don't set f_namemax. ntfs and ext2fs don't set f_namemeax and f_favail. fusefs doesn't set f_mntfromspec, f_favail and f_iosize. Also, make all filesystems use copy_statfs_info(), so that all statfs information is filled in correctly for the (sb != &mp->mnt-stat) case. ok stefan
2016-04-07Always call bread_cluster() instead of calling it only if the currentMartin Pieuchot
logical block is contiguous to the previous one. This logic is a left-over of the pre-bread_cluster() area. When the read-ahead version of bread(9) was used to prefetch blocks. Nowadays bread_cluster() do the right thing (tm). ok stefan@
2016-04-03Remove sparc special-casing from ufsdirhash_init(). This is not requiredMartin Natano
anymore since the kernel VM space increase work done in sparc about one year ago. from Miod Vallat; thanks! ok tobiasu
2016-03-27When pulling and unmounting an umass USB stick, the file systemAlexander Bluhm
could end up in an inconsistent state. The fstype dependent mp->mnt_data was NULL, but the general mp was still listed as a valid mount point. Next access to the file system would crash with a NULL pointer dereference. If closing the device fails, the mount point must go away anyway. There is nothing we can do about it. Remove the workaround for the EIO error in the general unmount code, but do not generate any error in the file system specific unmount functions. OK natano@ beck@

2016-02-27Move mnt_maxsymlink from struct mount to struct ufsmount.natano
The concept of differentiating between "short" and "long" symlinks is specific to ufs/, so it shouldn't creep into the generic fs layer. Inspired by a similar commit to NetBSD. While there replace all references to mnt_maxsymlinklen in ufs/ext2fs with EXT2_MAXSYMLINKLEN, which is the constant max short symlink len for ext2fs. This allows to get rid of some (mnt_maxsymlinklen == 0) checks there, which is always false for ext2fs. input and ok stefan@ ok millert@
2016-02-26Convert mnt_maxsymlinklen to unsigned.natano
This allows to remove some truncating casts in symlink handling code. Also, validate fs_maxsymlinklen in the superblock at mount time and on fsck to make sure we don't use bogus data. discussion & ok millert@, stefan@

2016-01-12Kill the "doclusterread" and "doclusterwrite" defines.Martin Pieuchot
They are defined to 0 since the import of ext2fs 19 years ago.
2016-01-12Remove the "doclusterread" and "doclusterwrite" buttons.Martin Pieuchot
Cluster read is unconditionnally enabled for FFS since some years and toggling "doclusterread" has no effect. OpenBSD no longer support write clustering since the Dynamic Buffer Cache went in, so there is reason to delay the call to bawrite(9). Tested by Mathieu, ok dlg@

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@
