features (except for file types in directory entries, which will be
supported soon).
Centralized the magic number and compatibility checking.
Dropped support for ancient (pre-0.2b) filesystems, as in the Linux
version. Our "support" consisted of printing more details in the error
message before failing at mount time.
Fix potential bug with directory reading.
Explicitly limit file size to 4GB (msdos can't handle larger files).
Slightly reorganize msdosfs_read() to reduce number of 'if's.
main changes are:
- many things are more dynamic; e.g., the inode size is a new parameter
in the superblock instead of a constant.
- extensions are controlled by new flags in the superblock.
- directory entries may have a file type field.
These changes are not used yet, except for a spelling change which affects
ext2_cnv.c
(mainly things that were lost or misformatted in a different way by
moving them to ext2_fs_i.h and back, and ifdefs for user mode that
were excessively edited).
(pci dev_id 0x21).
- Start the SCRIPTS processor without resetting the SCSI BUS
at initialization.
- Remove the "Host adapter CCB chain" (got useless given the
new queuing scheme).
- Display correctly the state of SCSI signals, when SCSI BUS
looks bad.
- Cosmetic changes in messages printed out at initialization.
- Notifications and messages on RESET conditions slightly
reworked.
- TEKRAM 24C16 NVRAM support fixed (also reported ok).
to avoid the namespace problems caused by <ufs/ufs/inode.h> #defining
i_mode, etc.
ext2_fs_i.h had nothing to do with the Linux version. It was a small
part of the Linux version of ext2_fs.h (the part that declares extra
in-core fields for an inode). We don't need it because we use the
ufs in-core inode for the extra fields.
It is being re-imported here, to keep our long source change history with
this source continuous.
src/contrib/grep will be deleted some time in the very near future.
Aaron Campbell <aaron@cs.dal.ca>.
Use SHIFT-PgUp and SHIFT-PgDn to scroll back and forward.
Aarons original code was enhanced to have a separate scrollbuffer
for every virtual terminal and to preserve the screen contents
when switching screen sizes.
The scrollbuffer size is currently fixed at 8 pages but this
will be made configurable through the use of scon(1) in the
near future.
For pcvt_kbd.h, a longstanding compiler warning was fixed by
using excessive backetizing of the key2ascii[] table.
4096 - sizeof struct mbuf, and set MAX_MRU and MAX_MTU
back to 2048.
2048 is big enough as an MTU/MRU, but we need to be able
to allocate larger mbufs after reassembling IP fragments.
