From 6a6798b8e47c71888945ec5cb55c703db19b956c Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Wed, 10 Aug 2005 20:35:54 +0000 Subject: Major rewrite of mount, umount, losetup. Untangled lots of code, shrunk things down a bit, fixed a number of funky corner cases, added support for several new features (things like mount --move, mount --bind, lazy unounts, automatic detection of loop mounts, and so on). Probably broke several other things, but it's fixable. (Bang on it, tell me what doesn't work for you...) Note: you no longer need to say "-o loop". It does that for you when necessary. Still need to add "user mount" support, which involves making mount suid. Not too hard to do under the new infrastructure, just haven't done it yet... The previous code had the following notes, that belong in the version control comments: - * 3/21/1999 Charles P. Wright - * searches through fstab when -a is passed - * will try mounting stuff with all fses when passed -t auto - * - * 1999-04-17 Dave Cinege...Rewrote -t auto. Fixed ro mtab. - * - * 1999-10-07 Erik Andersen . - * Rewrite of a lot of code. Removed mtab usage (I plan on - * putting it back as a compile-time option some time), - * major adjustments to option parsing, and some serious - * dieting all around. - * - * 1999-11-06 mtab support is back - andersee - * - * 2000-01-12 Ben Collins , Borrowed utils-linux's - * mount to add loop support. - * - * 2000-04-30 Dave Cinege - * Rewrote fstab while loop and lower mount section. Can now do - * single mounts from fstab. Can override fstab options for single - * mount. Common mount_one call for single mounts and 'all'. Fixed - * mtab updating and stale entries. Removed 'remount' default. - * --- libbb/mtab.c | 45 ++------------------------------------------- 1 file changed, 2 insertions(+), 43 deletions(-) (limited to 'libbb/mtab.c') diff --git a/libbb/mtab.c b/libbb/mtab.c index b1f74c476..fa4958c26 100644 --- a/libbb/mtab.c +++ b/libbb/mtab.c @@ -28,8 +28,8 @@ #include "libbb.h" #define MTAB_MAX_ENTRIES 40 -static const int MS_RDONLY = 1; /* Mount read-only. */ +#ifdef CONFIG_FEATURE_MTAB_SUPPORT void erase_mtab(const char *name) { struct mntent entries[MTAB_MAX_ENTRIES]; @@ -72,45 +72,4 @@ void erase_mtab(const char *name) } else if (errno != EROFS) bb_perror_msg(bb_path_mtab_file); } - -void write_mtab(char *blockDevice, char *directory, - char *filesystemType, long flags, char *string_flags) -{ - FILE *mountTable = setmntent(bb_path_mtab_file, "a+"); - struct mntent m; - - if (mountTable == 0) { - bb_perror_msg(bb_path_mtab_file); - return; - } - if (mountTable) { - int length = strlen(directory); - - if (length > 1 && directory[length - 1] == '/') - directory[length - 1] = '\0'; - - if (filesystemType == 0) { - struct mntent *p = find_mount_point(blockDevice, "/proc/mounts"); - - if (p && p->mnt_type) - filesystemType = p->mnt_type; - } - m.mnt_fsname = blockDevice; - m.mnt_dir = directory; - m.mnt_type = filesystemType ? filesystemType : "default"; - - if (*string_flags) { - m.mnt_opts = string_flags; - } else { - if ((flags | MS_RDONLY) == flags) - m.mnt_opts = "ro"; - else - m.mnt_opts = "rw"; - } - - m.mnt_freq = 0; - m.mnt_passno = 0; - addmntent(mountTable, &m); - endmntent(mountTable); - } -} +#endif -- cgit v1.2.3
