2003-09-23 | Replace select backends with poll backends. selscan() and pollscan() | Todd C. Miller | |
now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK | |||
2003-09-01 | match syscallargs comments with reality | Henning Brauer | |
from Patrick Latifi <patrick.l@hermes.usherb.ca> ok jason@ tedu@ | |||
2003-07-21 | remove caddr_t casts. it's just silly to cast something when the function | Ted Unangst | |
takes a void *. convert uiomove to take a void * as well. ok deraadt@ | |||
2003-06-23 | fix nfds type; tedu marc ok | Theo de Raadt | |
2003-06-02 | Remove the advertising clause in the UCB license which Berkeley | Todd C. Miller | |
rescinded 22 July 1999. Proofed by myself and Theo. | |||
2002-08-12 | Missing FRELE() call on writev(2) error condition; art@ ok. | Aaron Campbell | |
2002-08-11 | SCARG cleanup; okay millert@ | Niels Provos | |
2002-03-14 | First round of __P removal in sys | Todd C. Miller | |
2002-03-13 | On sparc, PAGE_SIZE and friends might not be a compile-time constant. | Miod Vallat | |
Instead of using a homegrown set of variables in this case, rely on uvmexp fields once uvm has been initialized. This requires a few #include <uvm/uvm_extern.h> here and there in the kernel as well. Idea from art@, changes by me. | |||
2002-02-13 | More FREF/FRELE on relevant places. Now, only sys_mmap and a bunch of ioctl ↵ | Artur Grabowski | |
functions in sys/compat are left. | |||
2002-02-08 | Require a FREFd file in dofilewrite{,v}. | Artur Grabowski | |
2002-02-08 | require a FREFd fp in dofilereadv. Fix some comments. | Artur Grabowski | |
2002-02-08 | - Rename FILE_{,UN}USE to FREF and FRELE. USE is a bad verb and we don't have | Artur Grabowski | |
the same semantics as NetBSD anyway, so it's good to avoid name collissions. - Always fdremove before freeing the file, not the other way around. - falloc FREFs the file. - have FILE_SET_MATURE FRELE the file (It feels like a good ortogonality to falloc FREFing the file). - Use closef as much as possible instead of ffree in error paths of falloc:ing functions. closef is much more careful with the fd and can deal with the fd being forcibly closed by dup2. Also try to avoid manually calling *fo_close when closef can do that for us (this makes some error paths mroe complicated (sys_socketpair and sys_pipe), but others become simpler (sys_open)). | |||
2002-02-05 | Add counting of temporary references to a struct file (as opposed to references | Artur Grabowski | |
from fd tables and other long-lived objects). This is to avoid races between using a file descriptor and having another process (with shared fd table) close it. We use a separate refence count so that error values from close(2) will be correctly returned to the caller of close(2). The macros for those reference counts are FILE_USE(fp) and FILE_UNUSE(fp). Make sure that the cases where closef can be called "incorrectly" (most notably dup2(2)) are handled. Right now only callers of closef (and {,p}read) use FILE_{,UN}USE correctly, more fixes incoming soon. | |||
2002-02-02 | Be more consistent about using fd_getfile where it matters. | Artur Grabowski | |
2001-11-14 | in poll, if fd is < 0, clear revents; bjy@mogua.org | Theo de Raadt | |
2001-10-26 | - every new fd created by falloc() is marked as larval and should not be used | Artur Grabowski | |
any anyone. Every caller of falloc matures the fd when it's usable. - Since every lookup in the fd table must now check this flag and all of them do the same thing, move all the necessary checks into a function - fd_getfile. | |||
2001-05-16 | No need to check M_WAIT/M_WAITOK malloc return values. (art@ ok) | Hakan Olsson | |
2000-11-10 | Change the ktrace interface functions from taking the trace vnode to taking the | Artur Grabowski | |
traced proc. The vnode is in the proc and all functions need the proc. | |||
2000-09-27 | replace MALLOC/FREE w/ malloc/free for non-constant-sized memory ↵ | Michael Shalayeff | |
allocations; art@ ok | |||
2000-07-07 | Isn't code sharing great? | Artur Grabowski | |
poll had the same timeout problem as select. | |||
2000-07-07 | When select is awakened by a select collission, we need to recalculate | Artur Grabowski | |
the timeout. | |||
2000-04-20 | p{read,write}{,v} from csapuntz, partial NetBSD origin I think | Theo de Raadt | |
2000-04-19 | Change struct file interface methods read and write to pass file offset in | Constantine Sapuntzakis | |
and out. Make pread/pwrite in netbsd & linux thread safe - which is the whole point anyway. | |||
1999-11-29 | revents already cleared; d | Theo de Raadt | |
1999-11-29 | handle invalid file descriptors in poll more carefully; d | Theo de Raadt | |
1999-08-04 | optimize poll() for small nfds, by avoiding malloc | Theo de Raadt | |
1999-05-24 | correct return value of poll(); noted by d@ | Theo de Raadt | |
1999-03-22 | in poll(), constrain nfds better, to avoid kvm starvation; alex | Theo de Raadt | |
1999-02-14 | Use IOV_MAX, not the deprecated UIO_MAXIOV | Todd C. Miller | |
1999-02-14 | readv/writev with iov_len == 0 is legal (was already ok in uipc_syscalls.c). | Todd C. Miller | |
Make the check more readable by comparing against SSIZE_MAX instead of checking for wraparound. This is safe because SSIZE_MAX * 2 <= SIZE_T_MAX. Fixes recno problems in the db routines exposed by a perl test. | |||
1998-07-28 | writev takes an int as param #3; theo | Todd C. Miller | |
1998-07-28 | For read, write, send, sendto, recv, recvfrom return EINVAL is size arg > ↵ | Todd C. Miller | |
SSIZE_MAX. For readv, writev, sendmsg, recvmsg return EINVAL if sum of the over iov_len values overflows an ssize_t. Based on what XPG 4.2 says (though XPG is not entirely consistent here). Basically since the return value is ssize_t allowing size > SSIZE_MAX is bad since people who (incorrectly mind you) check the return value for < 0 instead of == -1 will have bad things happen to them. | |||
1998-07-28 | Return EINVAL when msg_iovlen or iovcnt <= 0; Make uio_resid unsigned ↵ | Todd C. Miller | |
(size_t) and don't return EINVAL if it is < 0 in sys_{read,write}. Remove check for uio_resid < 0 uiomove() now that uio_resid is unsigned and brack remaining panics with #ifdef DIAGNOSTIC. vn_rdwr() must now take a size_t * as its 9th argument so change that and clean up uses of vn_rdwr(). Fixes 549 + more | |||
1998-02-09 | More missing type changes; pointed out by deraadt@OpenBSD.org | Thorsten Lockert | |
1997-11-06 | Updates for VFS Lite 2 + soft update. | Constantine Sapuntzakis | |
1997-10-06 | back out vfs lite2 till after 2.2 | Theo de Raadt | |
1997-10-06 | VFS Lite2 Changes | Constantine Sapuntzakis | |
1997-08-31 | for non-tty TIOCSPGRP/F_SETOWN/FIOSETOWN pgid setting calls, store uid | Theo de Raadt | |
and euid as well, then deliver them using new csignal() interface which ensures that pgid setting process is permitted to signal the pgid process(es). Thanks to newsham@aloha.net for extensive help and discussion. | |||
1997-01-27 | select subsystem si_pid becomes si_selpid, to not conflict against ↵ | Theo de Raadt | |
user/kernel siginfo si_pid #define | |||
1996-10-12 | i added a fair bit to this | Theo de Raadt | |
1996-05-18 | poll() as a system call | Theo de Raadt | |
1996-05-07 | if nfds > FD_SETSIZE, allocate room for the bitmasks inside the kernel; also | Theo de Raadt | |
selscan() now understands that it may possible be passed home-grown fd_set's larger than FD_SETSIZE. | |||
1996-04-21 | partial sync with netbsd 960418, more to come | Theo de Raadt | |
1996-03-03 | From NetBSD: 960217 merge | Niklas Hallqvist | |
1995-10-18 | initial import of NetBSD tree | Theo de Raadt | |
