idecref cwd in exit
2006-08-29 19:59:52 +00:00
rtm 03c70cc2e6 consistently ignore more than 14 chars in path component
forbid create or write of existing directory
mkdir("d1/d2/d3"), .. should refer to d2, not cwd
mkdir increase parent link count
2006-08-26 16:31:05 +00:00
rtm 5051da6de3 inode addrs[NDIRECT] -> NADDRS
fix race in mknod / creat
use last component in dirent in mknod, not path

kaashoek bdb6643303 set size for directories correctly in wdir and mkfs
mkdir
ls shows stat info for each dir entry
2006-08-14 14:13:52 +00:00
rtm e4bcd2a3a9 wdir now uses readi/writei 2006-08-13 20:06:42 +00:00
rtm 17e3cf15ba fix iget() bug that allocated in-use inode[] entries 2006-08-13 15:51:58 +00:00
rtm 211ff0c67e namei returns locked parent dir inode for create / unlink
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
2006-08-13 12:22:44 +00:00
kaashoek c372e8dc34 zero freed blocks
multi-block directories
track size of directory (size = number entries in use)
should namei (and other code that scans through directories) scan through all blocks of a directory and not use size?
2006-08-13 05:28:04 +00:00
rtm 9e5970d596 link() 2006-08-13 02:12:44 +00:00

don't increase length of directory

rtm cd93074e5b LRU disk cache replacement 2006-08-12 22:34:13 +00:00
kaashoek 22bac2cb9d free inode only when noone is holding a pointer to it. should fix open-unlink-
read problem, but untested
2006-08-12 22:03:01 +00:00
rtm 7ce01cf9be mknod set nlink = 1
usertests for concurrent create/delete, and read() after unlink()

kaashoek 0633b9715e unlink,mknod,create with multi-component pathnames should work now
remove console init code from userfs
2006-08-12 01:25:45 +00:00
kaashoek 24437cd554 fix deadlock---iput(dp) asap
working unlink, but doesn't free dir blocks that become empty
remove out-of-date comment in ioapic
2006-08-11 18:18:38 +00:00
rtm 17a856577f init creates console, opens 0/1/2, runs sh
sh accepts 0-argument commands (like userfs)
reads from console
2006-08-11 13:55:18 +00:00
rtm 5be0039ce9 interrupts could be recursive since lapic_eoi() called before rti
so fast interrupts overflow the kernel stack
fix: cli() before lapic_eoi()
2006-08-10 22:08:14 +00:00
rtm 8a8be1b8c3 low-level keyboard input (not hooked up to /dev yet)
fix acquire() to cli() *before* incrementing nlock
make T_SYSCALL a trap gate, not an interrupt gate
sadly, various crashes if you hold down a keyboard key...
