2011-10-03iwlagn: fix dangling scan requestJohannes Berg
commit 6c80c39d9a6986a566c30d797aae37bfb697eea3 upstream. If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.

commit 65d0f19e583e80e42b1c67c166bfc4dfdf6ab693 upstream. iwlegacy version of fix: commit effd4d9aece9184f526e6556786a94d335e38b71 Author: Johannes Berg <johannes.berg@intel.com> Date: Thu Sep 15 11:46:52 2011 -0700 iwlagn: do not use interruptible waits Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

2011-10-03libsas: fix failure to revalidate domain for anything but the first expander ↵Mark Salyzyn
child. commit 24926dadc41cc566e974022b0e66231b82c6375f upstream. In an enclosure model where there are chaining expanders to a large body of storage, it was discovered that libsas, responding to a broadcast event change, would only revalidate the domain of first child expander in the list. The issue is that the pointer value to the discovered source device was used to break out of the loop, rather than the content of the pointer. This still remains non-compliant as the revalidate domain code is supposed to loop through all child expanders, and not stop at the first one it finds that reports a change count. However, the design of this routine does not allow multiple device discoveries and that would be a more complicated set of patches reserved for another day. We are fixing the glaring bug rather than refactoring the code.

commit 96067723e46b0dd24ae7b934085ab4eff4d26a1b upstream. Following reports on the list, it looks like the 3e-9xxx driver will leak dma mappings every time we get a transient queueing error back from the card. This is because it maps the sg list in the routine that sends the command, but doesn't unmap again in the transient failure path (even though the command is sent back to the block layer).

2011-10-03firmware loader: allow builtin firmware load even if usermodehelper is disabledLinus Torvalds
commit caca9510ff4e5d842c0589110243d60927836222 upstream. In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware.

2011-10-03bnx2fc: Fix kernel panic when deleting NPIV portsBhanu Prakash Gollapudi
commit d36b3279e157641c345b12eddb3db78fb42da80f upstream. Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone as the physical port and shares the same LUN. This happens due to the fact that vport destroy and unsolicited ELS are scheduled to run on the same workqueue, and vport destroy destroys the lport and the unsolicited ELS tries to access the invalid lport. This patch fixes this issue by maintaining a list of valid lports and verifying if the lport is valid or not before accessing it.

commit 7851fe2c7f294d0beccf4c3d6af52e8247b89f00 upstream. Adapter Interface fixes and changes - Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi - Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle the new Code the same as the CQE_CODE_RECEIVE code except that there are two new checks for this code that will cause the driver to use the new V1 macros for rq_id and fcf_id. - Fix a bug in lpfc_prep_seq() where the size out of the first CQE was ONLY being used, even though multiple dmabufs make up the sequence, each have their own CQE with potentially different sizes. - Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3] fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly. - Do physical to logical translation before indexing into the active XRI array. - Populate physical vpi in the iocb data structure. - Put the current accumulated total in each IOCB in the chain as we are walking thru then. The last IOCB in the chain should have the total length of the sequence.

commit 6b07d30aca7e52f2881b8c8c20c8a2cd28e8b3d3 upstream. This patch changes the call of tpm_transmit by supplying the size of the userspace buffer instead of TPM_BUFSIZE. This got assigned CVE-2011-1161. [The first hunk didn't make sense given one could expect way less data than TPM_BUFSIZE, so added tpm_transmit boundary check over bufsiz instead The last parameter of tpm_transmit() reflects the amount of data expected from the device, and not the buffer size being supplied to it. It isn't ideal to parse it directly, so we just set it to the maximum the input buffer can handle and let the userspace API to do such job.] Signed-off-by: Rajiv Andrade <srajiv@linux.vnet.ibm.com> Signed-off-by: James Morris <jmorris@namei.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-10-03zorro: Defer device_register() until all devices have been identifiedGeert Uytterhoeven
commit a7f4d00a82feb5b311f765bf9522bc55bee0684f upstream. As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro devices can contain only one BAR, several Amiga Zorro II expansion boards (mainly graphics cards) contain multiple Zorro devices: a small one for the control registers and one (or more) for the graphics memory. The conversion of cirrusfb to the new driver framework introduced a regression: the driver contains a zorro_driver for the first Zorro device, and uses the (old) zorro_find_device() call to find the second Zorro device. However, as the Zorro core calls device_register() as soon as a Zorro device is identified, it may not have identified the second Zorro device belonging to the same physical Zorro expansion card. Hence cirrusfb could no longer find the second part of the Picasso II graphics card, causing a NULL pointer dereference. Defer the registration of Zorro devices with the driver framework until all Zorro devices have been identified to fix this. Note that the alternative solution (modifying cirrusfb to register a zorro_driver for all Zorro devices belonging to a graphics card, instead of only for the first one, and adding a synchronization mechanism to defer initialization until all have been found), is not an option, as on some cards one device may be optional (e.g. the second bank of 2 MiB of graphics memory on the Picasso IV in Zorro II mode).

commit 1ff9918b625457ce20d450d00f9ed0a12ba191b7 upstream. Problem: When initiator sends write command to target, target tries to assign new sequence. It allocates new exchangeID (RX_ID) always from non-offloaded pool (Non-offload EMA) Fix: Enhanced fcoe_oem_match routine to look at F_CTL flags and if it is exchange responder and command type is WRITEDATA, then function returns TRUE instead of FALSE. This function is used to determine which pool to use (offload pool of exchange is used only if this function returns TRUE).

2011-10-03libfc: Enhancement to RPORT state machine applicable only for VN2VN modeKiran Patil
commit 480584818a4bb3655d8d0d875ed60b427fc61cc5 upstream. Problem: Existing RPORT state machine continues witg FLOGI/PLOGI process only after it receices beacon from other end. Once claiming stage is over (either clain notify or clain repose), beacon is sent and state machine enters into operational mode where it initiates the rlogin process (FLOGI/PLOGI) to the peer but before this rlogin is initiated, exitsing implementation checks if it received beacon from other end, it beacon is not received yet, rlogin process is not initiated. Other end initiates FLOGI but peer end keeps on rejecting FLOGI, hence after 3 retries other end deletes associated rport, then sends a beacon. Once the beacon is received, peer end now initiates rlogin to the peer end but since associated rport is deleted FLOGI is neither accepted nor the reject response send out because rport is deleted. Hence unable to proceed withg FLOGI/PLOGI process and fails to establish VN2VN connection. Fix: VN2VN spec is not standard yet but based on exitsing collateral on T11, it appears that, both end shall send beacon and enter into 'operational mode' without explictly waiting for beacon from other end. Fix is to allow the RPORT login process as long as respective RPORT is created (as part of claim notification / claim response) even though state of RPORT is INIT. Means don't wait for beacon from peer end, if peer end initiates FLOGI (means peer end exist and responding). Notes: This patch is preparing the FCoE stack for target wrt offload. This is generic patch and harmless even if applied on storage initiator because 'else if' condition of function 'fcoe_oem_found' shall evaluate to TRUE only for targets.

2011-10-03qdio: clear shared DSCI before scheduling the queue handlerJan Glauber
commit b02f0c2ea25781e0f94b4fc8f6f85582057857b3 upstream. The following race can occur with qdio devices that use the shared device state change indicator: Device (Shared DSCI) CPU0 CPU1 =============================================================================== 1. DSCI 0 => 1, INT pending 2. Thinint handler * si_used = 1 * Inbound tasklet_schedule * DSCI 1 => 0 3. DSCI 0 => 1, INT pending 4. Thinint handler * si_used = 1 * Inbound tasklet_schedu le => NOP 5. Inbound tasklet run 6. DSCI = 1, INT surpressed 7. DSCI 1 => 0 The race would lead to a stall where new data in the input queue is not recognized so the device stops working in case of no further traffic. Fix the race by resetting the DSCI before scheduling the inbound tasklet so the device generates an interrupt if new data arrives in the above scenario in step 6.
