2017-05-30ext2fs: Mark superblock as not modified when writtenStefan Fritsch
I have seen spurious "file system not clean; please fsck(8)" warnings during "mount -ur". Set e2fs_fmod = 0 when writing the superblock (as ffs does). "Makes sense" deraadt@

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);

2016-05-22When 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 Then v_specmountpoint is no longer valid.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@
2016-04-27Pad 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
2016-03-27When 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@

2015-02-10First step towards making uiomove() take a size_t size argument:Miod Vallat

2014-07-14better type safety and KNF.Martin Pelikan
Because ext2fs has only 32-bit inode numbers, use ufsino_t as in FFS. Disk blocks are u_int32_t as well, because we don't support the 64BIT flag. When we do, there's going to be a lot more going on than just daddr_t. While there, add some journaling-related bits into the superblock to play with. ok guenther
2014-07-13kill fs2hXX/h2fsXX macros with letohXX/htoleXXMartin Pelikan
The reason being that ext2 structures are little-endian but JBD2 journal is big-endian. Don't confuse readers by talking about "file system endian". Some KNF while there. ok guenther
