you can write me in private?

thanks

Hi Andy928

Thanks for the sharing of this and the creation of the wiki.

Could really do with some help if you have a little spare time - I would like to try and combine the NIC drivers in the RS3413xs 3211 kernel with the DS3612xs 3202 kernel. Could you give me a couple of pointers - maybe step by step

Mucho thanko

FYI,

The releases 3202 and 3211 are BINARY COMPATIBLE. Both uses the same Linux kernel for x64: 3.2.30. You can mix modules from both sources, mainly because no modifications from 3202 to 3211 in the kernel.

Good input! Thanks

Hi, have i use only git version or can i use vanilla kernel from synogpl 3202 branch?

Kanedo · August 28, 2013

I built the kernel, but it sends a SIGTERM half way through booting and shuts down.

EDIT: nevermind. had incompatible modules in rd.gz

Does anyone know where the sources for the different (compiled) cgi scripts are located?

I am trying to find out how the disks/volumes are managed and am not getting any further from the cli commands alone; so i was trying to do a top down aproach;

unfortunately i cant find the source for the cgi scripts...

Are those not included in the source code (and where do they come from then)?

Thx

Synology apps managing disks are not open source :sad:

Hello,

I want to build my own xpenology with this tutorial: http://xpenology.com/wiki/en/building_xpenology

But I stop until I have to use the SetMicropId() function.

Can you help me, to use it and in which dir I have to find the output.

Thanks.

zslibra · December 2, 2013

I'm trying to build my own kernel, but I don't know how to patch the original synology kernel from andy's git. please help~~

gnoboot · January 8, 2014

Modifying DSM 4.3 synobios.ko in Linux.

1. View the source code and look for the second 'ba ff ff ff ff' (25e1) in SetMicropId function using objdump.

# objdump -S synobios.ko | less

orig:
   25da:       e8 00 00 00 00          callq  25df 
   25df:       85 c0                   test   %eax,%eax
   25e1:       ba ff ff ff ff          mov    $0xffffffff,%edx
   25e6:       75 c4                   jne    25ac 
   25e8:       0f be 04 24             movsbl (%rsp),%eax
   25ec:       31 d2                   xor    %edx,%edx
   25ee:       89 05 00 00 00 00       mov    %eax,0x0(%rip)        # 25f4

2. Replace the next entry (25e6), change it from '75 c4 0f be 04 24' to '48 31 c0 b0 42 90' using xxd.

# xxd -g 1 synobios.ko > synobios.hex
# sed -i 's/75 c4 0f be 04 24/48 31 c0 b0 42 90/' synobios.hex 
# xxd -r synobios.hex > synobios-edited.ko
# objdump -S synobios-edited.ko | less

   25e1:       ba ff ff ff ff          mov    $0xffffffff,%edx
   25e6:       48 31 c0                xor    %rax,%rax
   25e9:       b0 42                   mov    $0x42,%al
   25eb:       90                      nop
   25ec:       31 d2                   xor    %edx,%edx
   25ee:       89 05 00 00 00 00       mov    %eax,0x0(%rip)        # 25f4

3. To disable the logging message, find '80 7c 24 17 00' (395) and replace the next entry (39a) with 'eb d4' in synobios_poll function.

# objdump -S synobios.ko | less

orig:
    394:       c3                      retq
    395:       80 7c 24 17 00          cmpb   $0x0,0x17(%rsp)
    39a:       74 d4                   je     370 
    39c:       be 24 02 00 00          mov    $0x224,%esi

# sed -i 's/80 7c 24 17 00 74 d4/80 7c 24 17 00 eb d4/' synobios.hex
# xxd -r synobios.hex > synobios-edited.ko
# objdump -S synobios-edited.ko | less

I tried to compile 32 bit version myself by directions on this forum. I used 4.3 image bromolow (32bit) and Andys kernel from git. I just turned off x64, included VIA C7 platform, and VIA Rhine drivers in kernel, and while creating bzImage I got this error :

arch/x86/kernel/sys_i386_32.c: In function 'sys_SYNOmmap':
arch/x86/kernel/sys_i386_32.c:51: error: implicit declaration of function 'sys_mmap2'

Try to use x64 dsgpl source and not bromolow.

m4dm4n · February 23, 2014

Try to use x64 dsgpl source and not bromolow.

I used "gcc421_glibc236_x86-GPL.tgz" , and I still get the same error...

gnoboot · February 23, 2014

Did you get synogpl-3776-x64.tbz? Have you also tried using /source/linux-3.x/synoconfigs/x86 or /source/linux-3.x/synoconfigs/x86_64 config?

m4dm4n · February 23, 2014

Did you get synogpl-3776-x64.tbz? Have you also tried using /source/linux-3.x/synoconfigs/x86 or /source/linux-3.x/synoconfigs/x86_64 config?

I used

gcc420_glibc236_x64-GPL.tgz (extracted to /usr/local)

synogpl-3776-x64.tbz (extracted to /usr/local/x86_64-linux-gnu/)

andys kernel from github

Used menuconfig , turned off x64, used VIA C7 platform and Centaur support, and included VIA Rhine drivers.

Can you explain those synoconfigs with more details ?

After menuconfig, and modules building.

I would like to BUMP this post , since I'm very interested in details of the story, so I could build something for myself and for this forum,too. Obviously, wiki from the first post in thread isnt't informative enough.

gnoboot · February 26, 2014

Well, it's not easy if you haven't tried to compile your own kernel from Linux distribution. Once you know how to do it, then you can try again. Aside from Andy's original patch, you still need to figure out how to detect/enable drives that are not fully supported by DSM. I spent a week or two before having a working kernel, and it was built from scratch including Andy's patch which I ported from 4.1 to 4.3 kernel. I've even have to learn how to use synology toolkit to make my life easier. :wink: Good luck on your endeavor.

gnoboot · March 14, 2014

This patch works well with dsgpl-4.3 source code. It also works with dsgpl-5.0 source code but you have to manually edit the relevant files. Go start build your own kernel and if ever you give back to this community. You can't please everyone, some of them are blood sucking leeches!

At least you could discard those having less then 5 or 10 posts on this forum and just registered, asking directly for releases... :idea:
