The basic issue is that\nit means too many things and has too many side-effects.\n\nIt\u0027s possible to allow an unprivileged user to mount a filesystem if the\nuser owns the mountpoint, /bin/mount is setuid root, and the mount is\nset up in /etc/fstab with the \"user\" option.\n\nWhen doing this though, /bin/mount automatically adds the \"uid\u003d\" and\n\"gid\u003d\" options to the share. This is fortunate since the correct uid\u003d\noption is needed in order to tell the upcall what user\u0027s credcache to\nuse when generating the SPNEGO blob.\n\nOn a mount without unix extensions this is fine -- you generally will\nwant the files to be owned by the \"owner\" of the mount. The problem\ncomes in on a mount with unix extensions. With those enabled, the\nuid/gid options cause the ownership of files to be overriden even though\nthe server is sending along the ownership info.\n\nThis means that it\u0027s not possible to have a mount by an unprivileged\nuser that shows the server\u0027s file ownership info. The result is also\ninode permissions that have no reflection at all on the server. You\nsimply cannot separate ownership from the mode in this fashion.\n\nThis behavior also makes MultiuserMount option less usable. Once you\npass in the uid\u003d option for a mount, then you can\u0027t use unix ownership\ninfo and allow someone to share the mount.\n\nWhile I\u0027m not thrilled with it, the only solution I can see is to stop\nmaking uid\u003d/gid\u003d force the overriding of ownership on mounts, and to add\nnew mount options that turn this behavior on.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "50b64e3b77d569c217a48e078cd565dbd6462ad0", "tree": "2001150788641aad1f4824046d336f0b5d4dd32c", "parents": [ "b96d31a62f714566fa6420851b3bb3615c796322" ], "author": { "name": "Jeff Layton", "email": "jlayton@redhat.com", "time": "Tue Jun 02 06:55:20 2009 -0400" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Tue Jun 02 15:45:40 2009 +0000" }, "message": "cifs: fix IPv6 address length check\n\nFor IPv6 the userspace mount helper sends an address in the \"ip\u003d\"\noption.

We need to have the\nthread stay up until kthread_stop is called on it.\n\nOne option would be to not even try to tear things down until after\nkthread_stop is called. However, in the case where there is a problem\nsetting up the session, there\u0027s no real reason to try continuing the\nloop.\n\nThis patch allows the thread to clean up and prepare for exit under all\nthree conditions, but it has the thread go to sleep until kthread_stop\nis called. This allows us to simplify the shutdown code somewhat since\nwe can be reasonably sure that the thread won\u0027t exit after being\nsignaled but before kthread_stop is called.\n\nIt also removes the places where the thread itself set the tsk variable\nsince it appeared that it could have a potential race where the thread\nmight never be shut down.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nAcked-by: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "02eadeffda169a45946c79270ec19f45eeafb8e7", "tree": "b416ae6cd3d48b4188716cfd7fe7b90808bb28ac", "parents": [ "1b20d672188bf80baef60d515a123f556871a5ce" ], "author": { "name": "Jeff Layton", "email": "jlayton@redhat.com", "time": "Fri May 09 21:26:11 2008 +0000" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Sun May 11 17:45:43 2008 +0000" }, "message": "[CIFS] add local struct inode pointer to cifs_setattr\n\nClean up cifs_setattr a bit by adding a local inode pointer, and\nchanging all of the direntry-\u003ed_inode references to it.
