| * [CIFS] fix bad handling of EAGAIN error on kernel_recvmsg in ↵Steve French2007-10-171-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs_demultiplex_thread When kernel_recvmsg returns -EAGAIN or -ERESTARTSYS, then cifs_demultiplex_thread sleeps for a bit and then tries the read again. When it does this, it's not zeroing out the length and that throws off the value of total_read. Fix it to zero out the length. Can cause memory corruption: If kernel_recvmsg returns an error and total_read is a large enough value, then we'll end up going through the loop again. total_read will be a bogus value, as will (pdu_length-total_read). When this happens we end up calling kernel_recvmsg with a bogus value (possibly larger than the current iov_len). At that point, memcpy_toiovec can overrun iov. It will start walking up the stack, casting other things that are there to struct iovecs (since it assumes that it's been passed an array of them). Any pointer on the stack at an address above the kvec is a candidate for corruption here. Many thanks to Ulrich Obergfell for pointing this out.

| * [CIFS] Fix cifsd so shuts down when signing fails during mountSteve French2007-10-041-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | A reasonably common NAS server returns an error on the SetFSInfo of the Unix capabilities. Log a message for this alerting the user that the server may have problems with the Unix extensions, and telling them what they can do to workaround it. Unfortunately the server does not return other clues that we could easily use to turn the Unix Extension support off automatically in this case (since they claim to support it).

| * [CIFS] fix for incorrect session reconnectsSteve French2007-08-301-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs reconnect could end up happening incorrectly due to the small initial tcp recvmsg response. When the socket was within three bytes of being full and the recvmsg returned only 1 to 3 bytes of the initial 4 byte read of the RFC1001 length field. Fortunately this seems to be less common on more current kernels, but this fixes it so cifs tries to retrieve all 4 bytes of the initial tcp read.

* | Use helpers to obtain task pid in printksPavel Emelyanov2007-10-191-1/+1
|/ | | | | | | | | | | | | | | | The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

| * Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* [CIFS] Make sec=none force an anonymous mountJeff Layton2007-05-051-4/+4
| | | | | | | | | | | | | | | | We had a customer report that attempting to make CIFS mount with a null username (i.e. doing an anonymous mount) doesn't work. Looking through the code, it looks like CIFS expects a NULL username from userspace in order to trigger an anonymous mount. The mount.cifs code doesn't seem to ever pass a null username to the kernel, however. It looks also like the kernel can take a sec=none option, but it only seems to look at it if the username is already NULL. This seems redundant and effectively makes sec=none useless. The following patch makes sec=none force an anonymous mount. Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] UID/GID override on CIFS mounts to SambaSteve French2007-04-301-36/+43
| | | | | | | | | | | | | | | | | | When CIFS Unix Extensions are negotiated we get the Unix uid and gid owners of the file from the server (on the Unix Query Path Info levels), but if the server's uids don't match the client uid's users were having to disable the Unix Extensions (which turned off features they still wanted). The changeset patch allows users to override uid and/or gid for file/directory owner with a default uid and/or gid specified at mount (as is often done when mounting from Linux cifs client to Windows server). This changeset also displays the uid and gid used by default in /proc/mounts (if applicable). Also cleans up code by adding some of the missing spaces after "if" keywords per-kernel style guidelines (as suggested by Randy Dunlap when he reviewed the patch).

* [CIFS] Add IPv6 supportSteve French2007-04-251-4/+11
| | | | | | | | | | | | | | IPv6 support was started a few years ago in the cifs client, but lacked a kernel helper function for parsing the ascii form of the ipv6 address. Now that that is added (and now IPv6 is the default that some OS use now) it was fairly easy to finish the cifs ipv6 support. This requires that CIFS_EXPERIMENTAL be enabled and (at least until the mount.cifs module is modified to use a new ipv6 friendly call instead of gethostbyname) and the ipv6 address be passed on the mount as "ip=" mount option.
