ceph: stop selecting CRC32, CRYPTO, and CRYPTO_AES

2025-12-10T10:50:54+00:00

None of the CEPH_FS code directly requires CRC32, CRYPTO, or CRYPTO_AES. These options do get selected indirectly anyway via CEPH_LIB, which does need them, but there is no need for CEPH_FS to select them too. Signed-off-by: Eric Biggers Reviewed-by: Ilya Dryomov Signed-off-by: Ilya Dryomov

lib/crc: remove CONFIG_LIBCRC32C

2025-04-04T18:31:42+00:00

Now that LIBCRC32C does nothing besides select CRC32, make every option that selects LIBCRC32C instead select CRC32 directly. Then remove LIBCRC32C.

ceph: select FS_ENCRYPTION_ALGS if FS_ENCRYPTION

2024-01-15T14:40:50+00:00

The kconfig options for filesystems that support FS_ENCRYPTION are supposed to select FS_ENCRYPTION_ALGS. This is needed to ensure that required crypto algorithms get enabled as loadable modules or builtin as is appropriate for the set of enabled filesystems. Do this for CEPH_FS so that there aren't any missing algorithms if someone happens to have CEPH_FS as their only enabled filesystem that supports encryption.

ceph: convert ceph_readpage to netfs_readpage

Have the ceph KConfig select NETFS_SUPPORT. Add a new netfs ops structure and the operations for it. Convert ceph_readpage to use the new netfs_readpage helper. Signed-off-by: Jeff Layton Signed-off-by: Ilya Dryomov

libceph: replace HTTP links with HTTPS ones

2020-08-03T09:05:26+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

ceph: add selinux support

2019-07-08T12:01:42+00:00

When creating new file/directory, use security_dentry_init_security() to prepare selinux context for the new inode, then send openc/mkdir request to MDS, together with selinux xattr. security_dentry_init_security() only supports single security module and only selinux has dentry_init_security hook. So only selinux is supported for now. We can add support for other security modules once kernel has a generic version of dentry_init_security() Signed-off-by: "Yan, Zheng" Reviewed-by: Jeff Layton Signed-off-by: Ilya Dryomov

2018-01-01T19:45:37+00:00

This link is replicated in most filesystems' config stanzas. Referring to an archived version of that site is pointless as it mostly deals with patches; user documentation is available elsewhere.

ceph: use fscache as a local presisent cache

2013-09-06T16:50:11+00:00

Adding support for fscache to the Ceph filesystem. This would bring it to on par with some of the other network filesystems in Linux (like NFS, AFS, etc...) In order to mount the filesystem with fscache the 'fsc' mount option must be passed. Signed-off-by: Milosz Tanski Signed-off-by: Sage Weil
