Hello,
While using learning mode for the RC module, I encounter an error when
RSBAC tries to write to the disc :
rsbac_write_open(): failed to open file rc_tcfd on device 08:02 for
writing, error -30
rsbac_list_write_lol_buffers(): opening file rc_tcfd on device 08:02
failed with error -30!
free_buffers(): Freeing buffer of size 800
I have managed to reproduce this multiple times with this setup :
- with a non RSBAC kernel, I delete the entire configuration (sudo rm
-rf /rsbac.dat)
- I boot a first time with the RSBAC kernel, in softmode. There, I
execute a script which sets up the desired configuration (about 30
roles, 25 FD types, a few PROCESS types and that's it), and I shut down
the machine.
- I boot a second time with RSBAC, still in softmode, with RC and AUTH
learning modes activated. This is when, at some point, the error appears.
With rsbac_debug_write, I've got a little more detail :
fill_lol_buffer(): Filling buffers for list of lists rc_tcfd
rsbac_write_lists(): 1 lists of lists copied to buffers
rsbac_list_write_lol_buffers(): write list of lists rc_tcfd on device 08:02.
rsbac_write_open(): failed to open file rc_tcfd on device 08:02 for
writing, error -30
rsbac_list_write_lol_buffers(): opening file rc_tcfd on device 08:02
failed with error -30!
free_buffers(): Freeing buffer of size 800
rsbac_write_lists(): 4294967266 lists of lists written to disk
rsbac_write_lists(): 4294967266 lists written.
rsbac_write(): rsbac_write_lists() returned error -30
rsbac_write_reg(): 0 lists written.
It says 4294967266 lists were written, which is also -30 in signed
binary so I guess this is how the error is passed.
Anyway, before this error, there are multiple write operations that
behave normally.
The error repeats multiple times, always on file rc_tcfd, but in between
there are other write operations that produce no error.
