| 2017-01-31 | Read curproc from cpu structure, but be careful because after a schedule event | Frans Kaashoek | 1 | -9/+14 | |
| myproc() points to a different thread. myproc(); sched(); myproc(); // this proc maybe different than the one before sched Thus, in a function that operates on one thread better to retrieve the current process once at the start of the function. | |||||
| 2017-01-31 | Start of an experiment to remove the use of gs for cpu local variables. | Frans Kaashoek | 1 | -10/+11 | |
| 2016-09-26 | fix memory region validation in argptr() | MikeCAT | 1 | -1/+1 | |
| 2016-09-25 | Typo (Thanks to Austin Liew) | Frans Kaashoek | 1 | -1/+1 | |
| 2016-08-25 | Remove trailing white space with: | Frans Kaashoek | 1 | -1/+1 | |
| for f in *.{h,c}; do sed -i .sed 's/[[:blank:]]*$//' $f; done (Thanks to Nicolás Wolovick) | |||||
| 2012-08-22 | Remove left-over from some logging plan making complete syscalls atomic | Frans Kaashoek | 1 | -3/+1 | |
| 0 is not a system call (thanks to Peter Froehlich) | |||||
| 2012-02-17 | Make fetchint and fetchstr use proc instead of taking a struct proc | Austin Clements | 1 | -9/+9 | |
| Previously, these were inconsistent: they used their struct proc argument for bounds checking, but always copied the argument from the current address space (and hence the current process). Drop the struct proc argument and always use the current proc. Suggested by Carmi Merimovich. | |||||
| 2011-08-22 | Remove sys_init syscall | Frans Kaashoek | 1 | -9/+0 | |
| Invoke initlog from forkret on first user process | |||||

| 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]. | |||||
