2011-01-11 | make new code like old code | Russ Cox | 1 | -5/+4 | |
Variable declarations at top of function, separate from initialization. Use == 0 instead of ! for checking pointers. Consistent spacing around {, *, casts. Declare 0-parameter functions as (void) not (). Integer valued functions return -1 on failure, 0 on success. | |||||
2010-09-01 | Remove the stack guard page. Processes are now contiguous from 0 to ↵ | Austin Clements | 1 | -4/+1 | |
proc->sz, which means our syscall argument validation is correct. Add a pointer validation test and remove the stack test, which tested for the guard page. | |||||

2007-08-21 | Various cleanup: | rsc | 1 | -1/+0 | |
- 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]. | |||||

2006-08-13 | namei returns locked parent dir inode for create / unlink | rtm | 1 | -3/+3 | |
don't hold fd table lock across idecref() (latter does block i/o) idecref calls iput() in case last ref -> freeing inode dir size is 512 * # blocks, so readi/writei &c work unlink deletes dirent even if ip->nlink > 0 | |||||
