I don't know if this will turn into anything real - just learning rust.

rust-smf's Issues

double free after my_fmri()

Hitting this problem with my initial commit when running as part of an SMF service:

Before return cstring svc:/network/ssh:default
FMRI: svc:/network/ssh:default

When run with libumem debugging in the method script:

UMEM_DEBUG=default,verbose \
    /home/mgerdts/smf/target/debug/smf

This is found in the service log.

Before return cstring svc:/network/ssh:default
FMRI: ﾭ�ﾭ�ﾭ�ﾭ�ﾭ�ﾭ�
free(63da50): double-free or invalid buffer
stack trace:
libumem.so.1'umem_err_recoverable+0xcd
libumem.so.1'process_free+0xa0
libumem.so.1'umem_malloc_free+0x1d

Return something not derived from buf

If instead of

 32     let cstring = unsafe { CString::from_raw(ptr).into_string().unwrap() };
 33     println!("Before return cstring {}", cstring);
 34     Some(cstring)

I have:

 32     //let cstring = unsafe { CString::from_raw(ptr).into_string().unwrap() };
 33     //println!("Before return cstring {}", cstring);
 34     //Some(cstring)
 35     Some(String::from("svc://bogus:default"))

The service log gets the expected (bogus) value.

FMRI: svc://bogus:default
