2016-10-10Rename BIOS parameter block field from bsPBP to bsBPB. This typoAlexander Bluhm
has been fixed in FreeBSD in 2002. No binary change. From Alexander von Gernler; OK krw@
2016-10-09Do not check the SecPerTrack field of the BPB when mounting a MSDOSAlexander Bluhm
file system. In modern images the field is not set properly and the value is not used anyway. FreeBSD has removed the check already in 2008. From Alexander von Gernler; OK krw@

2016-08-30Revert "Implement VFS read clustering for MSDOSFS"Stefan Fritsch
This caused garbage to be written instead of blocks of 0-bytes if a file is extended by seeking past the end. This happens for example when extracting files containing lots of 0-bytes with tar. ok mpi@ Details of original commit: msdosfs_vnops.c revision 1.105 denode.h revision 1.28 date: 2016/01/13 10:00:55; author: mpi; commitid: ru9jHQwQX09BC5Bw; Implement VFS read clustering for MSDOSFS. 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@

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 Then v_specmountpoint is no longer valid.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@
2016-05-21Remove the -x flag from mount_msdos and always assume the execute bitMartin Natano
for readable directories, while making it subject to the mask option (-m in mount_msdos), so it is still possible to mount with non-executable directories, but with semantics that are easier to comprehend. This makes directory listings with default mount options work again. ok deraadt@

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@

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@

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@
