[KERNEL] CIFS + UTF8 NLS support for the official HTC Desire Froyo kernel

---

with the release of the source code for the bravo kernel this has become redundant

to be able to directly access my stuff on samba shares i made a _patch_ for the cifs code in 2.6.32.15 and built cifs.ko and nls_utf8.ko with arm-eabi-4.4.0

i thought i'd share them here in case it was of use to anyone else


this is how i installed them:

(boot into recovery mode)
$ adb shell mount /system
$ adb push cifs.ko /system/lib/modules
$ adb push nls_utf8.ko /system/lib/modules
$ adb shell chmod 644 /system/lib/modules/*.ko
$ adb shell "cd /system/lib/modules; ln -s . 2.6.32.15-gf9c0527"
$ adb shell umount /system
(reboot)

this is how i tested them:

sh-3.2$ su
sh-3.2# modprobe nls_utf8
sh-3.2# modprobe cifs
sh-3.2# busybox mount -t cifs -o user=<username>,password=<password>,uid=1000,gid=1015,file_mode=0775,dir_mode=0775,iocharset=utf8,nodfs //10.0.1.2/public2 /sdcard/smb/public2

(1015 is the gid of 'sdcard_rw')

as stated above it works with the stock htc kernel, which is 2.6.32.15-gf9c0527

check the output of uname -r

afaik the current nextsense comes with Myshkinbob's cifs module (although not with the latest one) - it's module version id was simply patched to suppress the version mismatch error message you got

here is mine if still interested:
(be sure to type "ln -s . 2.6.32.15-g1fc4045" instead of "ln -s . 2.6.32.15-gf9c0527" when installing)

Thx~! go to try it.

Greetings,

I tried using your patch on the source for the supersonic (evo) and it went in and compiled perfectly, i was able to do an insmod and loaded the driver fine, but when i go to do a mount the phone crashes.

any ideas?

(i have tried both the arm-eabi-4.4.0 and the arm-2010q1 toolchains)

Thanks!!

the patch does not cleanly apply to supersonic-2.6.32.15-g746f4f0, as it is for vanilla 2.6.32.15
please overwrite fs/cifs with the vanilla sources before you apply it

just tried and was able to build the very same .ko published in the first post (except for the buildstamp of course):

• pulled the supersonic kernel source from developer.htc.com
• overwrote fs/cifs/* with vanilla
• pulled & applied the patch from pastebin
• pulled .config from my phone
• in menuconfig
  • set the localversion (general setup)
  • selected cifs + nls_utf8 to be built as module
  • did _not_ touch the debug options already set
• did 'make modules'
• stripped the modules with arm-eabi-strip --strip-debug

insmod worked, mount worked, browsing the share worked


if you get crashes, check /proc/last_kmsg after reboot

What is considered "vanilla sources"?

I used git and pulled the whole android repo but am not finding the vanilla sources there...

do you mean the vanilla linux sources??


[edit]
i tried the cifs files from the vanilla linux source (same version) but the phone still crashes (even after the debug strip)

Should i try to use a different config (rather than the one from the supersonic templates?)

Do you have an evo that you tested this on?

Thanks again!!!
