From 82ab5bbac5d115b7cae4f3ca28f3ba8cce9431ba Mon Sep 17 00:00:00 2001 From: Flávio Cruz Date: Mon, 5 Mar 2018 02:58:41 +0100 Subject: Add file_utimens RPC to use a struct timespec and update the servers to use UTIME_NOW and UTIME_OMIT. * console-client/trans.c (netfs_attempt_utimes): Do not set current time ourself. * console/console.c (netfs_attempt_utimes): Likewise. * ftpfs/netfs.c (netfs_attempt_utimes): Likewise. * hostmux/node.c (netfs_attempt_utimes): Likewise. * usermux/node.c (netfs_attempt_utimes): Likewise. * nfs/ops.c (netfs_attempt_utimes): Likewise. * doc/hurd.texi (file_utimens): Add documentation. * hurd/fs.defs (file_utimens): Add RPC. * libdiskfs/file-utimes.c (diskfs_S_file_utimes): Move implementation and replace with translation layer with... (diskfs_S_file_utimens): ... new function. * libnetfs/file-utimes.c (netfs_S_file_utimes): Likewise with... (netfs_S_file_utimens): ... new function. * libnetfs/init-init.c: Include . (netfs_mtime): New variable. (netfs_init): New function. * libnetfs/netfs.h (netfs_attempt_utimes): Update documentation. * libnetfs/priv.h (netfs_mtime): Declare variable. * libtreefs/s-file.c (treefs_S_file_utimes): Convert time values and call treefs_s_file_utimens instead of treefs_s_file_utimes. * libtreefs/treefs-hooks.h: Replace TREEFS_HOOK_S_FILE_UTIMES with TREEFS_HOOK_S_FILE_UTIMENS. * libtreefs/treefs-s-hooks.h: Replace s_file_utimes with s_file_utimens. * libtrivfs/file-utimes.c (trivfs_S_file_utimens): New function. * libtrivfs/times.c (trivfs_set_atime): Try to use file_utimens before using file_utimes. (trivfs_set_mtime): Likewise. * nfsd/ops.c (complete_setattr): Likewise. * trans/fakeroot.c (netfs_attempt_utimes): Likewise. * nfs/nfs.c (xdr_encode_sattr_times): Do not set atime or mtime when they are NULL. * configure.ac: Look for file_futimens, and define UTIME_NOW/OMIT, for compatibility with old glibcs. --- nfs/nfs.c | 46 ++++++++++++++++++++++++++++++++++++---------- 1 file changed, 36 insertions(+), 10 deletions(-) (limited to 'nfs/nfs.c') diff --git a/nfs/nfs.c b/nfs/nfs.c index 77281566..c4d3e157 100644 --- a/nfs/nfs.c +++ b/nfs/nfs.c @@ -273,10 +273,26 @@ xdr_encode_sattr_times (int *p, struct timespec *atime, struct timespec *mtime) *(p++) = -1; /* uid */ *(p++) = -1; /* gid */ *(p++) = -1; /* size */ - *(p++) = htonl (atime->tv_sec); - *(p++) = htonl (atime->tv_nsec / 1000); - *(p++) = htonl (mtime->tv_sec); - *(p++) = htonl (mtime->tv_nsec / 1000); + if (atime) + { + *(p++) = htonl (atime->tv_sec); + *(p++) = htonl (atime->tv_nsec / 1000); + } + else + { + *(p++) = -1; /* no atime */ + *(p++) = -1; + } + if (mtime) + { + *(p++) = htonl (mtime->tv_sec); + *(p++) = htonl (mtime->tv_nsec / 1000); + } + else + { + *(p++) = -1; /* no mtime */ + *(p++) = -1; + } } else { @@ -284,12 +300,22 @@ xdr_encode_sattr_times (int *p, struct timespec *atime, struct timespec *mtime) *(p++) = 0; /* no uid */ *(p++) = 0; /* no gid */ *(p++) = 0; /* no size */ - *(p++) = htonl (SET_TO_CLIENT_TIME); /* atime */ - *(p++) = htonl (atime->tv_sec); - *(p++) = htonl (atime->tv_nsec); - *(p++) = htonl (SET_TO_CLIENT_TIME); /* mtime */ - *(p++) = htonl (mtime->tv_sec); - *(p++) = htonl (mtime->tv_nsec); + if (atime) + { + *(p++) = htonl (SET_TO_CLIENT_TIME); /* atime */ + *(p++) = htonl (atime->tv_sec); + *(p++) = htonl (atime->tv_nsec); + } + else + *(p++) = DONT_CHANGE; /* no atime */ + if (mtime) + { + *(p++) = htonl (SET_TO_CLIENT_TIME); /* mtime */ + *(p++) = htonl (mtime->tv_sec); + *(p++) = htonl (mtime->tv_nsec); + } + else + *(p++) = DONT_CHANGE; /* no mtime */ } return p; } -- cgit v1.2.3
