| Subject: [PATCH] nfsd: depend on CRYPTO_MD5 for legacy client tracking |
| |
| commit 38a2204f5298620e8a1c3b1dc7b831425106dbc0 upstream. |
| |
| The legacy client tracking infrastructure of nfsd makes use of MD5 to |
| derive a client's recovery directory name. As the nfsd module doesn't |
| declare any dependency on CRYPTO_MD5, though, it may fail to allocate |
| the hash if the kernel was compiled without it. As a result, generation |
| of client recovery directories will fail with the following error: |
| |
| NFSD: unable to generate recoverydir name |
| |
| The explicit dependency on CRYPTO_MD5 was removed as redundant back in |
| 6aaa67b5f3b9 (NFSD: Remove redundant "select" clauses in fs/Kconfig |
| 2008-02-11) as it was already implicitly selected via RPCSEC_GSS_KRB5. |
| This broke when RPCSEC_GSS_KRB5 was made optional for NFSv4 in commit |
| df486a25900f (NFS: Fix the selection of security flavours in Kconfig) at |
| a later point. |
| |
| Fix the issue by adding back an explicit dependency on CRYPTO_MD5. |
