| 2009-05-31 | inode reuse bug. | rsc | 1 | -1/+1 | |
| Suppose an inode has been used and freed. It is left marked I_VALID (the bug). Now ialloc comes along and reuses the inode. It writes the new inode type to disk and returns iget(dev, inum) to get the cache entry. Iget sees that the inode is valid and doesn't bother refreshing from disk. Now when the caller iupdates, it will write out a zero type and the file or directory has disappeared. | |||||

| 2007-08-28 | Change dev read/write functions | rsc | 1 | -2/+2 | |
| to take inode* instead of minor number. Unlock console inode during console_read and console_write. Otherwise background processes cannot write to console while the shell is reading it waiting for input. | |||||

| Various changes made while offline. + bwrite sector argument is redundant; use b->sector. + reformatting of files for nicer PDF page breaks + distinguish between locked, unlocked inodes in type signatures + change FD_FILE to FD_INODE + move userinit (nee proc0init) to proc.c + move ROOTDEV to param.h + always parenthesize sizeof argument | |||||

| 2007-08-21 | Various cleanup: | rsc | 1 | -105/+148 | |
| - Got rid of dummy proc[0]. Now proc[0] is init. - Added initcode.S to exec /init, so that /init is just a regular binary. - Moved exec out of sysfile to exec.c - Moved code dealing with fs guts (like struct inode) from sysfile.c to fs.c. Code dealing with system call arguments stays in sysfile.c - Refactored directory routines in fs.c; should be simpler. - Changed iget to return *unlocked* inode structure. This solves the lookup-then-use race in namei without introducing deadlocks. It also enabled getting rid of the dummy proc[0]. | |||||
