* fs: add ctime accessors infrastructureJeff Layton2023-07-101-0/+16
| | | | | | | | | | | | | | | | | struct timespec64 has unused bits in the tv_nsec field that can be used for other purposes. In future patches, we're going to change how the inode->i_ctime is accessed in certain inodes in order to make use of them. In order to do that safely though, we'll need to eradicate raw accesses of the inode->i_ctime field from the kernel. Add new accessor functions for the ctime that we use to replace them.

That means it will always be a false check in __ceph_finish_cap_snap(). When writing to buffer the kclient will take both 'Fb|Fw' caps and then write the contents to the buffer pages by increasing the 'i_wrbuffer_ref' and then just release both 'Fb|Fw'. This is different with the user space libcephfs, which will keep the 'Fb' being took and use 'i_wr_ref' instead of 'i_wrbuffer_ref' to track this until the buffer is flushed to Rados. We need to defer flushing the capsnap until the corresponding buffer pages are all flushed to Rados, and at the same time just trigger to flush the buffer pages immediately.

Also, when there are a lot of known client requests to recover from, the metrics requests will slow down the MDS rank from getting to the active state sooner. With this patch, we will send the metrics requests only when the MDS rank is in active state.

However, in the call stack of this commit, mft_ni in mi_read() is aliased with ni in attr_load_runs_vcn(), and it is also used in mi_read() at two places: mi_read() rw_lock = &mft_ni->file.run_lock -> No check attr_load_runs_vcn(mft_ni, ...) ni (namely mft_ni) is checked in the previous commit attr_load_runs_vcn(..., &mft_ni->file.run) -> No check Thus, to avoid possible null-pointer dereferences, the related checks should be added. These bugs are reported by a static analysis tool implemented by myself, and they are found by extending a known bug fixed in the previous commit. Thus, they could be theoretical bugs.

However, it fails to return a proper error code for the inconsistent attributes, which might lead to unpredicted memory accesses after return.
