[9fans] v9fs question
The documentation in the linux kernel says you merely mount -t 9p ipaddress /mntpoint this fails on my system since /sbin/mount tries to execute /sbin/mount.9p and fails. Am I supposed to have an /sbin/mount.9p? (Anyone know which ubunutu package should have this? If not, where I might find sources? Ironic since Ubuntu came with the 9p kernel module) Or should I be using a different mount program for the purpose? The linux Documentation/filesystems/9p.txt should probably be updated with more details, either way. Tim Newsham http://www.thenewsh.com/~newsham/

Re: [9fans] v9fs question
Try an ip address instead of the DNS name. For the DNS name you'll need a helper like 9mount.

Re: [9fans] mozilla on linuxemu3 gives ulimit not implemented
no, the syscall just returns -EIMPL because its not implemented... you can run linuxemu with -d option wich will log all syscalls and other debugging to strerr, or when something crashes attach acid to the broken process with the linuxemu.acid file and run utrace(Current()) and look if we hit unimplemented syscalls. but sys_ulimit() should be pretty harmless. you can implement that syscall if you want. i should make a small tutorial about how to add syscalls... 1. find out what the parameters of the syscall is (linuxassembly.org, lxr...) 2. add your syscall function prototype in fns.h like: int sys_mysyscall(int arg1, void *arg2); if structs are passed use void * and declare the struct near your implementation and cast the void* in it. for some complicated syscalls you can access the registers where arguments are passed in linux with current-ureg-reg but it should be avoided. the automatic convertion of syscalls to plan9 function passing allows the later implementation of for example a bsd syscall emulator. (bsd uses the traditional stack based argument passing) 3. add your syscalll to the linuxcalltab file like this: 1232mysyscall sys_mysyscall the first column is the syscall number, the 2nd is the number of arguments for the syscall function. the comes just a name and the last one is the function that will be called. 4. implement your function somewhere -- cinap ---BeginMessage--- i don't have the exact message; the machine is remote and currently powered off. is it my setup? ---End Message---

Re: [9fans] v9fs question
Using sqweek's 9mount is strongly recommended if you are using v9fs, not only it deals with the silly and deficient linux mount command (which somebody should submit a patch for some day I guess if we want to be taken seriously as an nfs replacement), but it also hides the ever changing v9fs mount flags under a more consistent and clear interface. The ability to mount and unmount 9p file servers without being root is just a great extra. http://sqweek.dnsdojo.org/code/9mount/ uriel P.S.: Oh, and I think debian even packages 9mount!

[9fans] C compiler question
Hi, all.
Yesterday I observed different sizeof() of a union in a library function
and in the main program. The reason seems to be a forgotten #include
in a library source.
union U
{
struct
{
fields of defined types// sizeof = 100
struct NeverDefined nf; // Unknown, definition
not #included
} S1
struct
{
fields of defined types// sizeof = 20
} S2
};
8c silently accept the above definition and sizeof(U) is 100. ???
The sources which include the definition of NeverDefined are
regularly compiled too and sizeof(U) = 100 + sizeof(NeverDefined).
This happens only if the undefined field is the last of the structure.
If it is followed by other (defined or not defined) field(s), the compiler
correctly detects the error.
Is this behaviour correct ?
Thanks in advance.
