I was running valgrind to check some of my kerberos authentication and
ran into this:
==11600== 28 bytes in 1 blocks are definitely lost in loss record 9 of 12
==11600== at 0x1B90340D: calloc (vg_replace_malloc.c:176)
==11600== by 0x125624: decode_krb5_enc_cred_part (in
/usr/lib/libkrb5.so.3.2)
==11600== by 0x149E5E: (within /usr/lib/libkrb5.so.3.2)
==11600== by 0x149F61: (within /usr/lib/libkrb5.so.3.2)
==11600== by 0x14A23B: krb5_rd_cred (in /usr/lib/libkrb5.so.3.2)
Its only 28 blocks, but if I repeat the authentication over and over it
grows quickly. It seems that when I get a forwarded tgt (krb5_fwd_tgt()
) and call krb5_rd_cred() it allocates some memory in the asn.1 decoder
and I'm not sure why its not cleaned up (or where it should be cleaned up).
All I know is that if I call krb5_rd_cred() 10 times I'll have 28 * 10
bytes of leaked memory.
Not sure what to do at this point. I'm running krb5 1.3.4.
Any ideas?
Thanks,
Derrick
