* fix memory leak in CIFSFindNextJeff Layton2008-05-12
| | | | | | | | | | | | | | | | | | | | | When CIFSFindNext gets back an -EBADF from a call, it sets the return code of the function to 0 and eventually exits. Doing this makes the cleanup at the end of the function skip freeing the SMB buffer, so we need to make sure we free the buffer explicitly when doing this. If we don't you end up with errors like this when unplugging the cifs kernel module: slab error in kmem_cache_destroy(): cache `cifs_request': Can't free all objects [<c046bdbf>] kmem_cache_destroy+0x61/0xf3 [<e0f03045>] cifs_destroy_request_bufs+0x14/0x28 [cifs] [<e0f2016e>] exit_cifs+0x1e/0x80 [cifs] [<c043aeae>] sys_delete_module+0x192/0x1b8 [<c04451fd>] audit_syscall_entry+0x14b/0x17d [<c0405413>] syscall_call+0x7/0xb ======================= Signed-off-by: Jeff Layton <jlayton@redhat.com>
* [CIFS] when not using unix extensions, check for and set ATTR_READONLY on ↵Jeff Layton2008-05-11
| | | | | | | | | | | | | | | | | | | | create and mkdir When creating a directory on a CIFS share without POSIX extensions, and the given mode has no write bits set, set the ATTR_READONLY bit. When creating a file, set ATTR_READONLY if the create mode has no write bits set and we're not using unix extensions. There are some comments about this being problematic due to the VFS splitting creates into 2 parts. I'm not sure what that's actually talking about, but I'm assuming that it has something to do with how mknod is implemented. In the simple case where we have no unix extensions and we're just creating a regular file, there's no reason we can't set ATTR_READONLY.

* [CIFS] Fix buffer overflow if server sends corrupt response to smallSteve French2007-11-13
| | | | | | | | | | | | | | | | | | | request In SendReceive() function in transport.c - it memcpy's message payload into a buffer passed via out_buf param. The function assumes that all buffers are of size (CIFSMaxBufSize + MAX_CIFS_HDR_SIZE) , unfortunately it is also called with smaller (MAX_CIFS_SMALL_BUFFER_SIZE) buffers. There are eight callers (SMB worker functions) which are primarily affected by this change: TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes, Lock and PosixLock CC: Dave Kleikamp <shaggy@austin.ibm.com> CC: Przemyslaw Wegrzyn <czajnik@czajsoft.pl> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Fix cifsd so shuts down when signing fails during mountSteve French2007-10-04
| | | | | | | | | | | | | | | | | | Fixes two problems: 1) we dropped down to negotiating lanman if we did not recognize the mechanism (krb5 e.g.) 2) we did not stop cifsd (thus will fail when doing rmod cifs with slab free errors) when we fail tcon but have a bad session (which is the case in which signing is required but we don't allow signing on the client) It also turns on extended security flag in the header when passing "sec=krb5" on mount command (although kerberos support is not done of course) Acked-by: Jeff Layton <jlayton@redhat.com> CC: Shaggy <shaggy@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Mount should fail if server signing off but client mount option ↵Jeff2007-07-06
| | | | | | | | | | | | | | | | requires it Currently, if mount with a signing-enabled sec= option (e.g. sec=ntlmi), the kernel does a warning printk if the server doesn't support signing, and then proceeds without signatures. This is probably OK for people that think to look at the ring buffer, but seems wrong to me. If someone explicitly requests signing, we should error out if that request can't be satisfied. They can then reattempt the mount without signing if that's ok. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
