* Remove unused "struct proc *" argument from the following functions:mpi2020-02-275-37/+34
| | | | | | | | | | | | | - ufs_chown() & ufs_chmod() - ufs_reclaim() - ext2fs_chown() & ext2fs_chmod() - ntfs_ntget() & ntfs_ntput() - ntfs_vgetex(), ntfs_ntlookup() & ntfs_ntlookupfile() While here use `ap->a_p' directly when it is only required to re-enter the VFS layer in order to help reducing the loop. ok visa@

* Syncronize filesystems to disk when suspending. Each mountpoint's vnodesderaadt2018-02-101-3/+3
| | | | | | | | | | are pushed to disk. Dangling vnodes (unlinked files still in use) and vnodes undergoing change by long-running syscalls are identified -- and such filesystems are marked dirty on-disk while we are suspended (in case power is lost, a fsck will be required). Filesystems without dangling or busy vnodes are marked clean, resulting in faster boots following "battery died" circumstances. Tested by numerous developers, thanks for the feedback.
* In uvm Chuck decided backing store would not be allocated proactivelyderaadt2017-12-111-13/+8
| | | | | | | | | | | | | | | | | | | | | | for blocks re-fetchable from the filesystem. However at reboot time, filesystems are unmounted, and since processes lack backing store they are killed. Since the scheduler is still running, in some cases init is killed... which drops us to ddb [noted by bluhm]. Solution is to convert filesystems to read-only [proposed by kettenis]. The tale follows: sys_reboot() should pass proc * to MD boot() to vfs_shutdown() which completes current IO with vfs_busy VB_WRITE|VB_WAIT, then calls VFS_MOUNT() with MNT_UPDATE | MNT_RDONLY, soon teaching us that *fs_mount() calls a copyin() late... so store the sizes in vfsconflist[] and move the copyin() to sys_mount()... and notice nfs_mount copyin() is size-variant, so kill legacy struct nfs_args3. Next we learn ffs_mount()'s MNT_UPDATE code is sharp and rusty especially wrt softdep, so fix some bugs adn add ~MNT_SOFTDEP to the downgrade. Some vnodes need a little more help, so tie them to &dead_vnops. ffs_mount calling DIOCCACHESYNC is causing a bit of grief still but this issue is seperate and will be dealt with in time. couple hundred reboots by bluhm and myself, advice from guenther and others at the hut

* When pulling an msdos formated umass stick during mount while thebluhm2016-05-221-2/+3
| | | | | | | | | | 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@
* Populate all necessary statfs members in .vfs_statfs. cd9660, udf,natano2016-04-261-10/+4
| | | | | | | | | | 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
* When pulling and unmounting an umass USB stick, the file systembluhm2016-03-271-6/+4
| | | | | | | | | | | | 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@

* Move mnt_maxsymlink from struct mount to struct ufsmount.natano2016-02-271-2/+1
| | | | | | | | | | | | | | 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@

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.

DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead.
