[ Upstream commit 7e140696 ] RGMII interfaces come in multiple flavors: RGMII with transmit or receive internal delay, no delays at all, or delays in both direction. This change extends the initial check for PHY_INTERFACE_MODE_RGMII to cover all of these variants since EEE should be allowed for any of these modes, since it is a property of the RGMII, hence Gigabit PHY capability more than the RGMII electrical interface and its delays.

[ Upstream commit 3f7352bf ] x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns. Fix this corner case by doing final iteration over bpf program. Fixes: 0a14842f ("net: filter: Just In Time compiler for x86-64") Reported-by:

[ Upstream commit d66bf7dd ] The code in __netdev_upper_dev_link() has an over-stringent loop detection logic that actually prevents valid configurations from working correctly. In particular, the logic returns an error if an upper device is already in the list of all upper devices for a given dev. This particular check seems to be a overzealous as it disallows perfectly valid configurations. For example: # ip l a link eth0 name eth0.10 type vlan id 10 # ip l a dev br0 typ bridge # ip l s eth0.10 master br0 # ip l s eth0 master br0 <--- Will fail If you switch the last two commands (add eth0 first), then both will succeed. If after that, you remove eth0 and try to re-add it, it will fail! It appears to be enough to simply check adj_list to keeps things safe. I've tried stacking multiple devices multiple times in all different combinations, and either rx_handler registration prevented the stacking of the device linking cought the error. Signed-off-by:

commit 45002267 upstream. Crush temporary buffers are allocated as per replica size configured by the user. When there are more final osds (to be selected as per rule) than the replicas, buffer overlaps and it causes crash. Now, it ensures that at most num-rep osds are selected even if more number of osds are allowed by the rule.

commit 161f873b upstream. We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again. Signed-off-by:

commit b9a5e5e1 upstream. Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence. Reported-and-tested-by:

commit 3c0213d1 upstream. When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1. This confuses userspace which knows how to deal with extra fingers when all the slots are used, but not when some are missing. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=90101Signed-off-by:

commit a8115776 upstream. The variable "sector" in "raid0_make_request()" was improperly updated by a call to "sector_div()" which modifies its first argument in place. Commit 47d68979 restored this variable after the call for later re-use. Unfortunetly the restore was done after the referenced variable "bio" was advanced. This lead to the original value and the restored value being different. Here we move this line to the proper place. One observed side effect of this bug was discarding a file though unlinking would cause an unrelated file's contents to be discarded. Signed-off-by:

commit 6e9eac2d upstream. If any memory allocation in resize_stripes fails we will return -ENOMEM, but in some cases we update conf->pool_size anyway. This means that if we try again, the allocations will be assumed to be larger than they are, and badness results. So only update pool_size if there is no error. This bug was introduced in 2.6.17 and the patch is suitable for -stable. Fixes: ad01c9e3 ("[PATCH] md: Allow stripes to be expanded in preparation for expanding an array") Signed-off-by:

Commit 178c2490 ("thermal: step_wise: cdev only needs update on a new target state") broke driver acerhdf. That driver abused the step_wise thermal governor until the bang_bang governor was available, and the optimization broke this usage model. Kernels v3.12 to v3.18 are affected. In v3.19 the acerhdf driver was switched to the bang_bang governor and that solved the problem. For kernels v3.12 to v3.17, the bang_bang governor isn't available yet so the easiest fix is to revert the optimization. Signed-off-by:

commit b0dc2b9b upstream. NUMA balancing is meant to be disabled by default on UMA machines but the check is using nr_node_ids (highest node) instead of num_online_nodes (online nodes). The consequences are that a UMA machine with a node ID of 1 or higher will enable NUMA balancing. This will incur useless overhead due to minor faults with the impact depending on the workload. These are the impact on the stats when running a kernel build on a single node machine whose node ID happened to be 1: vanilla patched NUMA base PTE updates 5113158 0 NUMA huge PMD updates 643 0 NUMA page range updates 5442374 0 NUMA hint faults 2109622 0 NUMA hint local faults 2109622 0 NUMA hint local percent 100 100 NUMA pages migrated 0 0 Signed-off-by:

commit 1b979372 upstream. Josh Stone reports: I've discovered a case where both arm and arm64 will miss a ptrace syscall-exit that they should report. If the syscall is entered without TIF_SYSCALL_TRACE set, then it goes on the fast path. It's then possible to have TIF_SYSCALL_TRACE added in the middle of the syscall, but ret_fast_syscall doesn't check this flag again. Fix this by always checking for a syscall trace in the fast exit path. Reported-by:

commit e531d0bc upstream. The journal revoke block recovery code does not check r_count for sanity, which means that an evil value of r_count could result in the kernel reading off the end of the revoke table and into whatever garbage lies beyond. This could crash the kernel, so fix that. However, in testing this fix, I discovered that the code to write out the revoke tables also was not correctly checking to see if the block was full -- the current offset check is fine so long as the revoke table space size is a multiple of the record size, but this is not true when either journal_csum_v[23] are set.

commit 9d506594 upstream. Currently when journal restart fails, we'll have the h_transaction of the handle set to NULL to indicate that the handle has been effectively aborted. We handle this situation quietly in the jbd2_journal_stop() and just free the handle and exit because everything else has been done before we attempted (and failed) to restart the journal. Unfortunately there are a number of problems with that approach introduced with commit 41a5b913 "jbd2: invalidate handle if jbd2_journal_restart() fails" First of all in ext4 jbd2_journal_stop() will be called through __ext4_journal_stop() where we would try to get a hold of the superblock by dereferencing h_transaction which in this case would lead to NULL pointer dereference and crash. In addition we're going to free the handle regardless of the refcount which is bad as well, because others up the call chain will still reference the handle so we might potentially reference already freed memory. Moreover it's expected that we'll get aborted handle as well as detached handle in some of the journalling function as the error propagates up the stack, so it's unnecessary to call WARN_ON every time we get detached handle. And finally we might leak some memory by forgetting to free reserved handle in jbd2_journal_stop() in the case where handle was detached from the transaction (h_transaction is NULL). Fix the NULL pointer dereference in __ext4_journal_stop() by just calling jbd2_journal_stop() quietly as suggested by Jan Kara. Also fix the potential memory leak in jbd2_journal_stop() and use proper handle refcounting before we attempt to free it to avoid use-after-free issues. And finally remove all WARN_ON(!transaction) from the code so that we do not get random traces when something goes wrong because when journal restart fails we will get to some of those functions.

commit 8f9cfeed upstream. when gsmtty_remove put dlci, it will cause memory leak if dlci->port's refcount is zero. So we do the cleanup work in .cleanup callback instead. dlci will be last put in two call chains. 1) gsmld_close -> gsm_cleanup_mux -> gsm_dlci_release -> dlci_put 2) gsmld_remove -> dlci_put so there is a race. the memory leak depends on the race. In call chain 2. we hit the memory leak. below comment tells. release_tty -> tty_driver_remove_tty -> gsmtty_remove -> dlci_put -> tty_port_destructor (WARN_ON(port->itty) and return directly) | tty->port->itty = NULL; | tty_kref_put ---> release_one_tty -> gsmtty_cleanup (added by our patch) So our patch fix the memory leak by doing the cleanup work after tty core did.

When gadget is composed with configfs configuration structure may be reused for different functions set. This bug happens because purge_configs_funcs() sets only next_interface_id to 0. Interface array still contains pointers to already freed interfaces. If in second try we add less interfaces than earlier we may access unallocated memory when trying to get interface descriptors.

commit 82ee3aeb upstream. Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.
