USB Keyboard and l4con
by Alexander Valitov 06 Apr '09

06 Apr '09

Hi, I've got the problem. l4con doesn't work with USB keyboard. It occurs with L4linux+l4con and even with simple txtmode con applications. "USB legacy support" is turned on. Here is how l4con complains: C.05:con | atkbd.c: Unknown key pressed (translated set 2, code 0x66 on is a0060/ C.05:con : serio0). C.05:con | atkbd.c: Use 'setkeycodes 66 <keycode>' to make it known. C.05:con | atkbd.c: Unknown key pressed (translated set 2, code 0x66 on is a0060/ How could it be solved? Best Regards, Alexander Valitov -- View this message in context: http://www.nabble.com/USB-Keyboard-and-l4con-tp22821747p22821747.html Sent from the L4 mailing list archive at Nabble.com.

Hi List, I have another question regarding L4Linux and IPC. Whenever I perform IPC-communication, I get the following debug output: l4lx| l4ts_free_task(): Could not return task. This message is repeated twice on every IPC-call. What is the cause of this and how do I get rid of this? ;) Thanks in advance!

Urgent help needed to port some drivers on Fiasco L4 µ-Kernel
by tapas kundu 03 Apr '09

03 Apr '09

Hi ALL, We are students of IIT Delhi. We are working on a project based on Fiasco L4 microkernel. We need to buid servers on L4 for ext2 filesystem support and usb web cam support. Could you please clear following doubts : 1) Does "fiasco l4 microkernel/ l4 env" provide support for ext2 filesystem or usb webcam ? 2) Does "fiasco l4 microkernel/ l4 env" provides Device Driver API library so that we can build driver for it ? 3) Do we need to build both usb driver and webcam driver in "fiasco l4 microkernel/ l4 env" to provide support for usb webcam ? 4) Does "fiasco l4 microkernel/ l4 env" provides l4 io driver for SATA or IDE harddisk ? Can we use that to build our ext2 filesystem support for it? Thansks & Regards Tapas Kumar Kundu

Questions about FLIPS
by Alexander Valitov 30 Mar '09

30 Mar '09

Hi, I've got some questions about FLIPS functionality. 1. Does flips contain internal routing mechanism? Can I get access to routing tables through NET_LINK socket interface? 2. Does flips contain netfilter or something like this? If yes, can I get access to it? 3. What about SNAT/IPmasquerading? Is it supported in some way? 4. Does flips support IPsec? Maybe another L4 package could provide such a support? AFAIK there was "Viaduct" and "nethub" projects. Seems that nethub is discontinued. I believe there should be some results. Does someone keep working in this direction?

L4 Server Dynamic Loading

while we could specify the initial servers on grub.conf so that they would run when the system reboots, I'm wondering how could I dynamically load L4 servers after that?

Hi, It seems that file l4/pkg/l4vfs/lib/libc_backends/socket_io/socket.c misses recvmsg() function. There is send(), sendto(), sendmsg(), recv(), recvfrom(), but no recvmsg(). Maybe it's just oversight?

IPC problem with dice-3.3.0
by Marcel Selhorst 27 Mar '09

27 Mar '09

Hi l4-hackers, I am currently having some issues with dice-3.3: First of all, the dice-generated code differs in header- and client file, meaning that the header defines functions with int DICE_CV somefunction() while the outcoming c-file is int somefunction() This leads to compile errors due to conflicting declarations... But as soon as you remove DICE_CV, everything compiles fine. The second problem I have regards IPC-calls: I am using the latest otc-snapshot (2008-12-10 with l4linux-2.6.27) and have written a small IDL-interface as follows: dummy.idl: == interface dummy { void hello(void); } == The server (running under L4Linux) registers itself at the names-service as "dummy" and starts the server_loop... It implements the dummy_hello_component as follows: == void dummy_hello_component (CORBA_Object _dice_corba_obj, CORBA_Server_Environment *_dice_corba_env) { /* do nothing*/ printf("Hello\n"); } == Additionally, I have written 2 clients, one native L4 application and one based on L4Linux, which implement the client-stub as follows: == static l4_threadid_t threadId; static CORBA_Environment env; names_query_name("dummy", &threadId); LOG_printf("Dummy found with threadId: %x\n",threadId); dummy_hello_call(&threadId, &env); == The native client (started via bmodfs) receives a pagefault, cause it is trying to write?! to address 0: == dummytest| Dummy found with threadId: 11a0001 dummytest| L4RM: [PF] write at 0x00000000, ip 02000272, src 11.02 dummytest| [11.0] l4rm/lib/src/pagefault.c:81:__unknown_pf(): dummytest| unhandled page fault --PANIC, 'g' for exit------------------------------------IP: 02005755 [dummy.rm] (11.00) jdb: == And the L4Linux-client crashes with a segfault: == dummy_t[42]: segfault at 2 ip 08048312 sp bf4092ec error 6 in dummy_test[8048000+76000] == The strange thing is: If I compile the idl-file with dice-3.2.1, the dummy example works, BUT as soon as my interfaces get more complex, e.g., something like this: int write ([in] long start, [in] long offset, [in] long bytes_to_write, [in, size_is(write_len), max_is(MAX_PAGE_SIZE)] char *write_buffer, [out] long *write_len); IPC crashes with pagefaults / segfaults again even with dice-3.2.1... My Fiasco-config is attached. Do you have any ideas where the problem might be? Do I have to pay attention to specific configuration options, if the IPC-server is running in an L4Linux?

[BUGREPORT] DDE timer handling
by Andre Puschmann 27 Mar '09

27 Mar '09

Hi list, I am working on a port of an Ethernet-based fieldbus stack to TUDOS. The stack is a Linux kernel module so I am utilizing DDE as a wrapper for this. Things seem to work like this: the module creates a kernel thread which does the network polling in an endless loop. The loop basically looks like this: while (1) receive_data() process_data() send_data() schedule_func() Here, schedule_func() does the following: set_current_state(TASK_INTERRUPTIBLE); schedule_timeout(1); Which I interpret as something like wait for 10ms (assume HZ==100) or an event to occur and then restart the loop. schedule_timeout() creates a new timer with the specified timeout and calls plain schedule(). Ok, this works quite good up to an arbitrary point where the complete system stops working. Sometimes, the system runs 2min, sometimes 1h and sometimes 3h, so it varies a lot. After the stuck occurs, using jdb, I see the kernel_thread waiting for a message to be woken up. On the other hand, the timer_thread which has to throw this messages is in idle state. I am still a L4 beginner, especially in debugging its subsystems. However, for me that looks like we lost a timer event somewhere. I replaced schedule_timeout() with msleep(10) which omits the timer stuff and that works for me here for hours without any stuck. Before further tracking down this issue I want to make sure that you guys don't have any patch pending that fixes that problem, have u? Best regards, Andre

fnmatch() is absent in ulibc port
by Alexander Valitov 26 Mar '09

26 Mar '09

Hi, I'm porting some Linux application to L4Env using your ulibc port. The application uses fnmatch() function from libc. For some reason this function is absent in BUILD-DIR/lib/x86_586/libuc_c.a file, but at the same time BUILD-DIR/include/uclibc/fnmatch.h is present. So compilation completes without error, but linkage fails. Was it done intentionally? ./l4/pkg/uclibc/lib/uclibc/Makefile does not even try to compile ./l4/pkg/uclibc/lib/contrib/uclibc/libc/misc/fnmatch/fnmatch.c. See DIRS variable definition. If it was done intentionally. Why the header is in the way?

L4linux Installation Problem(Double Page Fault)
by Sid Yu 24 Mar '09

24 Mar '09

Right now I'm working on a project which utilizes Fiasco/L4Env/L4Linux environment, so I'm just trying to set it up on my workstation. Unfortunately, I have encountered some problems which bothered me for days. Could anybody help me out? Any help or suggestions would be appreciated, Thank you. Here is the boot information when I try to boot L4linux: (I have also attached a screen shot) .................................................. loader : vmlinux: starting sigma0-style application loader : vmlinux: loading binary loader : vmlinux,#d: Entry at 00009f3c => 00400000 loader : vmlinux,#d: Started loader : vmlinux,#d: Double PF (r) at 00000000 eip 00000000 (D.00) -- Double PF,"g" for kill------------------------------IP: 013043a5 [loader.pager] (c.03) jdb: http://www.nabble.com/file/p22525172/Double_PF.jpg Here is some of my setup info: VMware version: 6.5 Host OS: Fedora 10 (Linux Kernel Version: 2.6.27) Gcc Version: 4.3.2 Grub Version: 0.97 L4Env config: default build command: make oldconfig O=/path-to-buildu-dir && make O=/path-to-buildu-dir Fiasco config: default + 'Handle and preserve segments' option was enabled CPU type: Intel Pentium / AMD k5 build command: cd kernel/fiasco && make BUILDDIR=/path-to-buildk-dir cd /path-to-buildk-dir && make menuconfig make L4Linux config: x86-native_defconfig + L4 build directory was set to '/path-to-buildu-dir' build command: cd l4linux-2.6 && make x86-native_defconfig && make menuconfig make Grub Config: title L4Linux (Fiasco/L4Env/L4Linux) kernel (hd0,0)/boot/l4linux/bootstrap -modaddr=0x02000000 module (hd0,0)/boot/l4linux/main -nokdb -serial_esc module (hd0,0)/boot/l4linux/sigma0 module (hd0,0)/boot/l4linux/roottask task modname "bmodfs" attached 5 modules module (hd0,0)/boot/l4linux/names module (hd0,0)/boot/l4linux/log module (hd0,0)/boot/l4linux/dm_phys --isa=0x00800000 module (hd0,0)/boot/l4linux/simple_ts -t 300 module (hd0,0)/boot/l4linux/rtc module (hd0,0)/boot/l4linux/l4io module (hd0,0)/boot/l4linux/bmodfs module (hd0,0)/boot/l4linux/cfg/l4linux26.cfg module (hd0,0)/boot/l4linux/libloader.s.so module (hd0,0)/boot/l4linux/libld-l4.s.so module (hd0,0)/boot/l4linux/vmlinux module (hd0,0)/boot/l4linux/drops-rd.rd (I download this file from L4linux website) module (hd0,0)/boot/l4linux/loader --fprov=BMODFS l4linux26.cfg l4linux26.cfg: sleep 1 task "vmlinux" "mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram l4env_rd=drops-rd.rd" all_sects_writable allow_vga BTW: When I tried to compile L4Env, the linker complains it couldn't find libz.a(by -lz option), so I build libz.a under l4/pkg/zlib separately and copied it to the build/lib directory manually, and the whole thing works! I'm not sure whether it's a problem of the Makefile or a problem of my configuration environment. -- View this message in context: http://www.nabble.com/L4linux-Installation-Problem%28Double-Page-Fault%29-t… Sent from the L4 mailing list archive at Nabble.com.

Problem with L4Linux ORe stub driver
by Alexander Valitov 24 Mar '09

24 Mar '09

Hi, I'm trying to run L4Linux with ORe. I can successfully run L4Linux without ORe and can run ORe without L4Linux (arping works). But when I try to run L4Linux with ORe, boot process hangs up after message from stub driver: eth0: Overwriting IRQ type for IRQ 10 with l4ore type! eth0: request_irq(10, ...) l4lx | l4x_ore_irq_startup l4lx | l4lx_thread_create: Created thread 10.0b (L4OreRcv) eth0: interface up. After some time a following message (with some additional info - see it in a boot log given at the end of letter) appears: BUG: soft lockup - CPU#0 stuck for 61s! [pump:92] I guess it caused by the ORe stub driver but it's only guess. What could it be? What could I try to do? Here is my 'L4Linux cfg file' and 'boot log': L4Linux cfg file: task "vmlinuz4" "earlyprintk=yes mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram l4env_rd=drops.rd" all_sects_writable allow_vga allow_cli Boot log: Booting 'L4Linux-2.6 + l4con + ORE' kernel /boot/L4Linux/bootstrap [Multiboot-elf, <0x2d0000:0x700c:0x3e94>, shtab=0x2db118, entry=0x2d0000] modaddr 0x02000000 Setting module load address to 0x2000000 module /boot/L4Linux/main -nokdb -serial_esc -comspeed 115200 -comport 1 [Multiboot-module @ 0x2000000, 0x5d410 bytes] module /boot/L4Linux/sigma0 [Multiboot-module @ 0x205e000, 0x36f4a bytes] module /boot/L4Linux/roottask task modname "loader" allow_cli task modname "bmo dfs" attached 5 modules [Multiboot-module @ 0x2095000, 0x9cc3f bytes] module /boot/L4Linux/names [Multiboot-module @ 0x2132000, 0x415fd bytes] module /boot/L4Linux/log [Multiboot-module @ 0x2174000, 0x3e5c0 bytes] module /boot/L4Linux/l4io [Multiboot-module @ 0x21b3000, 0x26dd06 bytes] module /boot/L4Linux/events [Multiboot-module @ 0x2421000, 0x40c62 bytes] module /boot/L4Linux/dm_phys --isa=0x00800000 -v --events [Multiboot-module @ 0x2462000, 0x9b17d bytes] module /boot/L4Linux/simple_ts -t 300 [Multiboot-module @ 0x24fe000, 0x4d625 bytes] module /boot/L4Linux/rtc [Multiboot-module @ 0x254c000, 0x3023b bytes] module /boot/L4Linux/ore [Multiboot-module @ 0x257d000, 0x3af5c8 bytes] module /boot/L4Linux/l4con [Multiboot-module @ 0x292d000, 0x187b11 bytes] module /boot/L4Linux/bmodfs [Multiboot-module @ 0x2ab5000, 0xa629a bytes] module /boot/L4Linux/l4linux263.cfg [Multiboot-module @ 0x2b5c000, 0x98 bytes] module /boot/L4Linux/libloader.s.so [Multiboot-module @ 0x2b5d000, 0x9ceee bytes] module /boot/L4Linux/libld-l4.s.so [Multiboot-module @ 0x2bfa000, 0x78c39 bytes] module /boot/L4Linux/vmlinuz4 [Multiboot-module @ 0x2c73000, 0x369fcf bytes] module /boot/L4Linux/drops.rd [Multiboot-module @ 0x2fdd000, 0x1000000 bytes] module /boot/L4Linux/loader --fprov=BMODFS l4linux263.cfg [Multiboot-module @ 0x3fdd000, 0xdb766 bytes] vbeset 0x117 [VESA 3.0 info @ 0x40b9000, 0x2ff bytes] boot Welcome to Fiasco(ia32)!

Grub Question + some other information needed
by mcs082803＠cse.iitd.ernet.in 23 Mar '09

23 Mar '09

Hi List I know that a grub different from the standard is used. I downloaded the grub on Adam's site but have no idea how to get that diff file to work. There is a ReadMe called as grub-0.97-os.3.README that gives some info but I don't just get the fact that it is to boot from network. I am just booting from the hard disk using standard grub (with -modaddr option used with bootstrap), but now I need to use the vbeset command (and maybe others in future), so I really need that grub. I have done these $ wget ftp://alpha.gnu.org/gnu/grub/grub-0.97.tar.gz $ wget http://os.inf.tu-dresden.de/~adam/grub/0.97/grub-0.97-os.7.diff.gz $ tar xzf grub-0.97.tar.gz $ cd grub-0.97 $ zcat ../grub-0.97-os.7.diff.gz | patch -p0 so what i do next? just install this grub (using install) or something else? because the next steps in readme seem like specific for diskless booting from some network. and what version of adam's grub should I download (i used the grub-0.97-os.7.diff.gz because it seemed latest). some other things (unrelated to above) -- can i make programs that could write output to some file on hard disk. Is somewhere a reference manual that gives info about what datatypes and functions can i use in a general program i write, e.g. to do something equivalent of scanf,malloc,etc. Regards, Ashish

difficulties with Loader
by Alexander Valitov 23 Mar '09

23 Mar '09

Hi, During my play with 'run' application (./l4/pkg/loader/examples/run) I've discovered two issues. They both applies to the chain 'run'<->'loader'<->'simple_ts'. 1. First issue: I start 'con_demo1' application using 'run' utility 'l' command, then try to kill it. Kill process fails with following output (here F.02 is 'run' thread, 10.00 is 'con_demo1' task): A.00:simplets| task_kill(): Kill 10.00 from E.02 but owner is F.02 E.02:loader | l4ts_kill_task(): failed (dest=10.00 server=A.00, ret=-11, exc 0) E.02:loader | con_demo1,#10: Error -11 (not owner) killing task (ignored) It looks like inconsistency in loader's behavior. 'run' uses l4loader_app_open_call() and l4loader_app_kill_call() l4loader's methods to start and kill application, but l4loader_app_kill_call() invocation always fails as 'loader' explicitly set 'run' as owner: /* set client as owner so that client is able to kill that task */ if ((error = l4ts_owner(app->tid, app->owner))) { app_msg(app, "Error %d (%s) setting ownership", error, l4env_errstr(error)); return error; } But 'l4loader' implicitly passes itself as caller when he makes call to l4ts_kill_task() in app_cleanup_extern() function. So I think inconsistency is quite obvious. A straightforward solution here is just to remove l4ts_owner() invocation from l4loader's code. Do I miss something? 2. Second issue Scenario is the same as before: 'con_demo1' is started by 'run' and then killed by using run's 'kill' command. In this case: - 'run' calls l4loader_app_kill_call() - 'l4loader' calles app_cleanup_extern() - app_cleanup_extern() calles l4ts_kill_task(app->tid, 0) As a result simple_ts will not free allocated TaskNo for 'con_demo1' (use run's 'A' command for TS state after task has been killed). I think last argument for l4ts_kill_task() function is wrong. It should look like that: l4ts_kill_task(app->tid, L4TS_KILL_FREE) here is a path for the last issue: Index: app.c =================================================================== --- app.c (revision 439) +++ app.c (working copy) @@ -1488,7 +1488,7 @@ if (!l4_is_invalid_id(app->tid)) { killing = app->tid; - if ((error = l4ts_kill_task(app->tid, 0))) + if ((error = l4ts_kill_task(app->tid, L4TS_KILL_FREE))) app_msg(app, "Error %d (%s) killing task (ignored)", error, l4env_errstr(error)); else Any objections?

DEFAULT_RELOC and roottask
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, I try to run l4con examples with grub script given in ./l4/pkg/l4con/doc/menu.lst (slightly modified/updated). The menu.lst starts con_demo1, con_demo2 and con_demo3. Boot process gives me this error: #0d: loading "/boot/test/con_demo1" from [026ce000-0277262c] to [00800000-008250b5][00826000-0083d000] entry at 00068370 via trampoline page code symbols at [3a30e000-3a313000] (20kB), lines at [3a2fd000-3a30e000] (68kB) #0e: loading "/boot/test/con_demo2" from [02773000-02804e08] to [00800000-00815d11] Roottask: cannot load binary because address at 00800000 not free loaded module: [02773000-02804e08) /boot/test/con_demo2 overlaps with: [00800000-00826000) #0d con_demo1 I found that Makefile specifies DEFAULT_RELOC_x86 variable as: DEFAULT_RELOC_x86 = 0x00800000 As a result -Ttext=0x800000 option is added to 'ld' invocation options. I thought that is the root of problem and commented variable, but It didn't help. Build system started to use default DEFAULT_RELOC value 0x01000000 from ./l4/mk/binary.inc and roottask gives the same error with new 0x01000000 address. 1. I thought that DEFAULT_RELOC specifies virtual address not a physical one. Am I right? 2. If answer to my first question is 'yes'. Why in this case roottask relocates a code? It is strange as roottask operates with physical memory addresses. 3. When am I supposed to specify DEFAULT_RELOC variable? In which situation? 4. Why do we need the relocation performed by root task at all? Why can't we just use appropriate mapping to addresses where GRUB loaded ELF modules? Each server starts in its own virtual address space, so I think it's possible. Why was it done that way? What is the problem with described approach (without relocation)? 5. I've been playing around with L4Env,L4Linux and stuff for a while but have never faced with mentioned problem. Are there anything special about the way how con_demo1,2,3 are built? I mean Root task relocates another modules to the next free 4K aligned address but con_demo1,2,3 modules to some exact address. Why does it happened? 6. There is ./l4/pkg/l4con/examples/Makeconf file with link addresses specification. But according to "Building Infrastructure for DROPS (BID) Specification" only Makeconf.local file is included into generated Makefile from project directories. Why is it where?

Build DROPS on 64bit Host for 32bit Target
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, Is it possible to build DROPS on 64bit HOST OS for 32bit TARGET (architecture there Fiasco will be executed) if corresponding cross-compiler is already available? I tried but it looks like DICE ignores TARGET architecture and generates IPC code for HOST architecture (64 bit). It seems that there are no problems with Fiasco, L4Env and L4Linux.

Patch for DICE that fix issue with AMD64 host
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, I would like to submit path that fix problem when you use DICE to produce code for i32 on 64bit OS. Please see this thread for details: http://www.nabble.com/Build-DROPS-on-64bit-Host-for-32bit-Target-td22563295… The root of problem was that DICE determines some data type's size as sizeof(type). This is obviously wrong if DICE is a 64bit application and a code is generated for 32bit system. I would like to thank Roman I Khimov for spending his time for locating the issue and kindly providing us with the following patch.

Problem with Fiasco under QEMU
by Alexander Valitov 18 Mar '09

18 Mar '09

Hi, I've encountered problems under QEMU. Problems occur in many different configs but this is the simplest way to reproduce: Build Fiasco with default config, only "Handle and preserve segments" shall be turned on. Configure ORe for RTL-8139 NIC only and build L4Env. Build L4Linux with x86-ux_defconfig, only "ORe stub driver" shall be turned on. Boot with following QEMU command: qemu /dev/sdb -no-kqemu -serial telnet:localhost:5555,server NOTES: 1. I use USB flash stick but image file could be used as well with the same result. 2. You may pass option -net nic,model=rtl8139 but result will be the same Error log (in second case uKernel crashes): If you don't load ORe module you should see: l4lx | setup_l4env_memory: Forcing superpages for main memory DMphys | [9.0] dm_phys/server/src/open.c:98:__create_ds(): DMphys | DMphys: memory allocation size 65536KB pool 0 failed! l4lx | [F.4] dm_mem/lib/clientlib/src/open.c:80:l4dm_mem_open(): l4lx | libdm_mem: open dataspace at 9.00 failed (ret -2, exc 0) l4lx | setup_l4env_memory: Can't get main memory of 64MB: out of memory(-2)! l4lx | Main thread running, waiting...
