Code: void __weak arch_release_thread_stack(unsigned long *stack) { } Commit Message: fork: fix incorrect fput of ->exe_file causing use-after-free Commit 7c051267931a ("mm, fork: make dup_mmap wait for mmap_sem for write killable") made it possible to kill a forking task while it is waiting to acquire its ->mmap_sem for write, in dup_mmap(). However, it was overlooked that this introduced an new error path before a reference is taken on the mm_struct's ->exe_file. Since the ->exe_file of the new mm_struct was already set to the old ->exe_file by the memcpy() in dup_mm(), it was possible for the mmput() in the error path of dup_mm() to drop a reference to ->exe_file which was never taken. This caused the struct file to later be freed prematurely. Fix it by updating mm_init() to NULL out the ->exe_file, in the same place it clears other things like the list of mmaps. This bug was found by syzkaller. It can be reproduced using the following C program: #define _GNU_SOURCE #include <pthread.h> #include <stdlib.h> #include <sys/mman.h> #include <sys/syscall.h> #include <sys/wait.h> #include <unistd.h> static void *mmap_thread(void *_arg) { for (;;) { mmap(NULL, 0x1000000, PROT_READ, MAP_POPULATE|MAP_ANONYMOUS|MAP_PRIVATE, -1, 0); } } static void *fork_thread(void *_arg) { usleep(rand() % 10000); fork(); } int main(void) { fork(); fork(); fork(); for (;;) { if (fork() == 0) { pthread_t t; pthread_create(&t, NULL, mmap_thread, NULL); pthread_create(&t, NULL, fork_thread, NULL); usleep(rand() % 10000); syscall(__NR_exit_group, 0); } wait(NULL); } } No special kernel config options are needed. It usually causes a NULL pointer dereference in __remove_shared_vm_struct() during exit, or in dup_mmap() (which is usually inlined into copy_process()) during fork. Both are due to a vm_area_struct's ->vm_file being used after it's already been freed.

Code: views::View* GetPermissionAnchorView(Browser* browser) { return bubble_anchor_util::GetPageInfoAnchorView(browser); } Commit Message: Elide the permission bubble title from the head of the string. Long URLs can be used to spoof other origins in the permission bubble title. This CL customises the title to be elided from the head, which ensures that the maximal amount of the URL host is displayed in the case where the URL is too long and causes the string to overflow. Implementing the ellision means that the title cannot be multiline (where elision is not well supported). Note that in English, the window title is a string "$ORIGIN wants to", so the non-origin component will not be elided. In other languages, the non-origin component may appear fully or partly before the origin (e.g. in Filipino, "Gusto ng $ORIGIN na"), so it may be elided there if the URL is sufficiently long. This is not optimal, but the URLs that are sufficiently long to trigger the elision are probably malicious, and displaying the most relevant component of the URL is most important for security purposes.

In case if a flow cannot be added (e.g. flow action is go-to group id which does not exist), OVS tries to revert back all previous flows which were successfully applied from the same bundle. This is possible since OVS maintains list of old flows which were replaced by flows from the bundle. While reinserting old flows ovs asserts due to check on rule state != RULE_INITIALIZED. This will work only for new flows, but for old flow the rule state will be RULE_REMOVED. This is causing an assert and OVS crash. The ovs assert check should be modified to != RULE_INSERTED to prevent any existing rule being re-inserted and allow new rules and old rules (in case of revert) to get inserted. Here is an example to trigger the assert: $ ovs-vsctl add-br br-test -- set Bridge br-test datapath_type=netdev $ cat flows.txt flow add table=1,priority=0,in_port=2,actions=NORMAL flow add table=1,priority=0,in_port=3,actions=NORMAL $ ovs-ofctl dump-flows -OOpenflow13 br-test cookie=0x0, duration=2.465s, table=1, n_packets=0, n_bytes=0, priority=0,in_port=2 actions=NORMAL cookie=0x0, duration=2.465s, table=1, n_packets=0, n_bytes=0, priority=0,in_port=3 actions=NORMAL $ cat flow-modify.txt flow modify table=1,priority=0,in_port=2,actions=drop flow modify table=1,priority=0,in_port=3,actions=group:10 $ ovs-ofctl bundle br-test flow-modify.txt -OOpenflow13 First flow rule will be modified since it is a valid rule. However second rule is invalid since no group with id 10 exists. Bundle commit tries to revert (insert) the first rule to old flow which results in ovs_assert at ofproto_rule_insert__() since old rule->state = RULE_REMOVED.

For tun device, this is a problem because a timer etc. are already initialized and it expects ->ndo_uninit() to clean them up. We could move these initializations into a ->ndo_init() so that register_netdevice() knows better, however this is still complicated due to the logic in tun_detach(). Therefore, I choose to just call dev_get_valid_name() before register_netdevice(), which is quicker and much easier to audit. And for this specific case, it is already enough.

Do a (manual) revert of: a9e7f6544b9c ("sched/fair: Fix O(nr_cgroups) in load balance path") It turns out that the list_del_leaf_cfs_rq() introduced by this commit is a surprising property that was not considered in followup commits such as: 9c2791f936ef ("sched/fair: Fix hierarchical order in rq->leaf_cfs_rq_list") As Vincent Guittot explains: "I think that there is a bigger problem with commit a9e7f6544b9c and cfs_rq throttling: Let take the example of the following topology TG2 --> TG1 --> root: 1) The 1st time a task is enqueued, we will add TG2 cfs_rq then TG1 cfs_rq to leaf_cfs_rq_list and we are sure to do the whole branch in one path because it has never been used and can't be throttled so tmp_alone_branch will point to leaf_cfs_rq_list at the end. 2) Then TG1 is throttled 3) and we add TG3 as a new child of TG1. 4) The 1st enqueue of a task on TG3 will add TG3 cfs_rq just before TG1 cfs_rq and tmp_alone_branch will stay on rq->leaf_cfs_rq_list. With commit a9e7f6544b9c, we can del a cfs_rq from rq->leaf_cfs_rq_list. So if the load of TG1 cfs_rq becomes NULL before step 2) above, TG1 cfs_rq is removed from the list. Then at step 4), TG3 cfs_rq is added at the beginning of rq->leaf_cfs_rq_list but tmp_alone_branch still points to TG3 cfs_rq because its throttled parent can't be enqueued when the lock is released. tmp_alone_branch doesn't point to rq->leaf_cfs_rq_list whereas it should. So if TG3 cfs_rq is removed or destroyed before tmp_alone_branch points on another TG cfs_rq, the next TG cfs_rq that will be added, will be linked outside rq->leaf_cfs_rq_list - which is bad. In addition, we can break the ordering of the cfs_rq in rq->leaf_cfs_rq_list but this ordering is used to update and propagate the update from leaf down to root." Instead of trying to work through all these cases and trying to reproduce the very high loads that produced the lockup to begin with, simplify the code temporarily by reverting a9e7f6544b9c - which change was clearly not thought through completely. This (hopefully) gives us a kernel that doesn't lock up so people can continue to enjoy their holidays without worrying about regressions. ;-) [ mingo: Wrote changelog, fixed weird spelling in code comment while at it. ] Analyzed-by: Xie XiuQi <xiexiuqi@huawei.com> Analyzed-by: Vincent Guittot <vincent.guittot@linaro.org> Reported-by: Zhipeng Xie <xiezhipeng1@huawei.com> Reported-by: Sargun Dhillon <sargun@sargun.me> Reported-by: Xie XiuQi <xiexiuqi@huawei.com> Tested-by: Zhipeng Xie <xiezhipeng1@huawei.com> Tested-by: Sargun Dhillon <sargun@sargun.me> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Vincent Guittot <vincent.guittot@linaro.org> Cc: <stable@vger.kernel.org> # v4.13+ Cc: Bin Li <huawei.libin@huawei.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Tejun Heo <tj@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Fixes: a9e7f6544b9c ("sched/fair: Fix O(nr_cgroups) in load balance path") Link: http://lkml.kernel.org/r/1545879866-27809-1-git-send-email-xiexiuqi@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org> CWE ID: CWE-400

Code: static void netif_free_tx_queues(struct net_device *dev) { kvfree(dev->_tx); } Commit Message: tunnels: Don't apply GRO to multiple layers of encapsulation. When drivers express support for TSO of encapsulated packets, they only mean that they can do it for one layer of encapsulation. Supporting additional levels would mean updating, at a minimum, more IP length fields and they are unaware of this. No encapsulation device expresses support for handling offloaded encapsulated packets, so we won't generate these types of frames in the transmit path. However, GRO doesn't have a check for multiple levels of encapsulation and will attempt to build them. UDP tunnel GRO actually does prevent this situation but it only handles multiple UDP tunnels stacked on top of each other. This generalizes that solution to prevent any kind of tunnel stacking that would cause problems.

Code: static const struct arm_pmu *__init xscale1pmu_init(void) { return &xscale1pmu; } Commit Message: perf: Remove the nmi parameter from the swevent and overflow interface The nmi parameter indicated if we could do wakeups from the current context, if not, we would set some state and self-IPI and let the resulting interrupt do the wakeup. For the various event classes: - hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from the PMI-tail (ARM etc.) - tracepoint: nmi=0; since tracepoint could be from NMI context. - software: nmi=[0,1]; some, like the schedule thing cannot perform wakeups, and hence need 0. As one can see, there is very little nmi=1 usage, and the down-side of not using it is that on some platforms some software events can have a jiffy delay in wakeup (when arch_irq_work_raise isn't implemented). The up-side however is that we can remove the nmi parameter and save a bunch of conditionals in fast paths.

Code: static struct sctp_transport *sctp_addr_id2transport(struct sock *sk, struct sockaddr_storage *addr, sctp_assoc_t id) { struct sctp_association *addr_asoc = NULL, *id_asoc = NULL; struct sctp_af *af = sctp_get_af_specific(addr->ss_family); union sctp_addr *laddr = (union sctp_addr *)addr; struct sctp_transport *transport; if (!af || sctp_verify_addr(sk, laddr, af->sockaddr_len)) return NULL; addr_asoc = sctp_endpoint_lookup_assoc(sctp_sk(sk)->ep, laddr, &transport); if (!addr_asoc) return NULL; id_asoc = sctp_id2assoc(sk, id); if (id_asoc && (id_asoc != addr_asoc)) return NULL; sctp_get_pf_specific(sk->sk_family)->addr_to_user(sctp_sk(sk), (union sctp_addr *)addr); return transport; } Commit Message: sctp: do not peel off an assoc from one netns to another one Now when peeling off an association to the sock in another netns, all transports in this assoc are not to be rehashed and keep use the old key in hashtable. As a transport uses sk->net as the hash key to insert into hashtable, it would miss removing these transports from hashtable due to the new netns when closing the sock and all transports are being freeed, then later an use-after-free issue could be caused when looking up an asoc and dereferencing those transports. This is a very old issue since very beginning, ChunYu found it with syzkaller fuzz testing with this series: socket$inet6_sctp() bind$inet6() sendto$inet6() unshare(0x40000000) getsockopt$inet_sctp6_SCTP_GET_ASSOC_ID_LIST() getsockopt$inet_sctp6_SCTP_SOCKOPT_PEELOFF() This patch is to block this call when peeling one assoc off from one netns to another one, so that the netns of all transport would not go out-sync with the key in hashtable. Note that this patch didn't fix it by rehashing transports, as it's difficult to handle the situation when the tuple is already in use in the new netns. Besides, no one would like to peel off one assoc to another netns, considering ipaddrs, ifaces, etc. are usually different.

Callbacks which want the full value then call path_name(), which concatenates the two. But this is an inefficient interface; the path is a strbuf, and we could simply append "c" to it temporarily, then roll back the length, without creating a new copy. So we could improve this by teaching the callsites of path_name() this trick (and there are only 3). But we can also notice that no callback actually cares about the broken-down representation, and simply pass each callback the full path "a/b/c" as a string. The callback code becomes even simpler, then, as we do not have to worry about freeing an allocated buffer, nor rolling back our modification to the strbuf. This is theoretically less efficient, as some callbacks would not bother to format the final path component. But in practice this is not measurable. Since we use the same strbuf over and over, our work to grow it is amortized, and we really only pay to memcpy a few bytes.

We've been bitten by the Simple Default Stylesheet being out of sync with the real html.css twice this week. The Simple Default Stylesheet was invented years ago for Mac: http://trac.webkit.org/changeset/36135 It nicely handles the case where you just want to create a single WebView and parse some simple HTML either without styling said HTML, or only to display a small string, etc. Note that this optimization/complexity *only* helps for the very first document, since the default stylesheets are all static (process-global) variables. Since any real page on the internet uses a tag not covered by the simple default stylesheet, not real load benefits from this optimization. Only uses of WebView which were just rendering small bits of text might have benefited from this. about:blank would also have used this sheet. This was a common application for some uses of WebView back in those days. These days, even with WebView on Android, there are likely much larger overheads than parsing the html.css stylesheet, so making it required seems like the right tradeoff of code-simplicity for this case.

As a transport uses sk->net as the hash key to insert into hashtable, it would miss removing these transports from hashtable due to the new netns when closing the sock and all transports are being freeed, then later an use-after-free issue could be caused when looking up an asoc and dereferencing those transports. This is a very old issue since very beginning, ChunYu found it with syzkaller fuzz testing with this series: socket$inet6_sctp() bind$inet6() sendto$inet6() unshare(0x40000000) getsockopt$inet_sctp6_SCTP_GET_ASSOC_ID_LIST() getsockopt$inet_sctp6_SCTP_SOCKOPT_PEELOFF() This patch is to block this call when peeling one assoc off from one netns to another one, so that the netns of all transport would not go out-sync with the key in hashtable. Note that this patch didn't fix it by rehashing transports, as it's difficult to handle the situation when the tuple is already in use in the new netns. Besides, no one would like to peel off one assoc to another netns, considering ipaddrs, ifaces, etc. are usually different.

Code: static int crypto_ablkcipher_report(struct sk_buff *skb, struct crypto_alg *alg) { return -ENOSYS; } Commit Message: crypto: user - fix info leaks in report API Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

Then we convert to the number of buffer pages needed. nr_page = DIV_ROUND_UP(size, BUF_PAGE_SIZE) but this time size is 18446744073709551360 and 2^64 - (18446744073709551360 + 4080 - 1) = -3823 Thus it overflows and the resulting number is less than 4080, which makes 3823 / 4080 = 0 an nr_pages is set to this. As we already checked against the minimum that nr_pages may be, this causes the logic to fail as well, and we crash the kernel. There's no reason to have the two DIV_ROUND_UP() (that's just result of historical code changes), clean up the code and fix this bug.

Two callers of ext3_msg omit the prefix and pass the format string as the second parameter and the first parameter to the format string as the third parameter. In both cases this string comes from an arbitrary source. Which means the string may contain format string characters, which will lead to undefined and potentially harmful behavior. The issue was introduced in commit 4cf46b67eb("ext3: Unify log messages in ext3") and is fixed by this patch.

Also, the call to inet_sk_copy_descendant() was backuping ->auto_asconf_list through the copy but was not honoring ->do_auto_asconf, which could lead to list corruption if it was different between both sockets. This commit thus fixes the list handling by using ->addr_wq_lock spinlock to protect the list. A special handling is done upon socket creation and destruction for that. Error handlig on sctp_init_sock() will never return an error after having initialized asconf, so sctp_destroy_sock() can be called without addrq_wq_lock. The lock now will be take on sctp_close_sock(), before locking the socket, so we don't do it in inverse order compared to sctp_addr_wq_timeout_handler(). Instead of taking the lock on sctp_sock_migrate() for copying and restoring the list values, it's preferred to avoid rewritting it by implementing sctp_copy_descendant(). Issue was found with a test application that kept flipping sysctl default_auto_asconf on and off, but one could trigger it by issuing simultaneous setsockopt() calls on multiple sockets or by creating/destroying sockets fast enough. This is only triggerable locally. Fixes: 9f7d653b67ae ("sctp: Add Auto-ASCONF support (core).")

Code: TabContents* Browser::GetTabContentsAt(int index) const { TabContentsWrapper* wrapper = tabstrip_model()->GetTabContentsAt(index); if (wrapper) return wrapper->tab_contents(); return NULL; } Commit Message: Implement a bubble that appears at the top of the screen when a tab enters fullscreen mode via webkitRequestFullScreen(), telling the user how to exit fullscreen. This is implemented as an NSView rather than an NSWindow because the floating chrome that appears in presentation mode should overlap the bubble. Content-initiated fullscreen mode makes use of 'presentation mode' on the Mac: the mode in which the UI is hidden, accessible by moving the cursor to the top of the screen. On Snow Leopard, this mode is synonymous with fullscreen mode. On Lion, however, fullscreen mode does not imply presentation mode: in non-presentation fullscreen mode, the chrome is permanently shown. It is possible to switch between presentation mode and fullscreen mode using the presentation mode UI control. When a tab initiates fullscreen mode on Lion, we enter presentation mode if not in presentation mode already. When the user exits fullscreen mode using Chrome UI (i.e. keyboard shortcuts, menu items, buttons, switching tabs, etc.) we return the user to the mode they were in before the tab entered fullscreen. BUG=14471 TEST=Enter fullscreen mode using webkitRequestFullScreen. You should see a bubble pop down from the top of the screen. Need to test the Lion logic somehow, with no Lion trybots.

That assumption is true for almost every op, but not for 32-bit right shifts, because those can propagate information towards the least significant bit. Fix it by always truncating inputs for 32-bit ops to 32 bits. Also get rid of the coerce_reg_to_size() after the ALU op, since that has no effect.

Analyze the following code, commit message, and CWE ID. Determine whether it has a vulnerability. If it does, return '1'; if it doesn't, return '0'.
Code: static int ovl_create_upper(struct dentry *dentry, struct inode *inode, struct kstat *stat, const char *link, struct dentry *hardlink) { struct dentry *upperdir = ovl_dentry_upper(dentry->d_parent); struct inode *udir = upperdir->d_inode; struct dentry *newdentry; int err; inode_lock_nested(udir, I_MUTEX_PARENT); newdentry = lookup_one_len(dentry->d_name.name, upperdir, dentry->d_name.len); err = PTR_ERR(newdentry); if (IS_ERR(newdentry)) goto out_unlock; err = ovl_create_real(udir, newdentry, stat, link, hardlink, false); if (err) goto out_dput; ovl_dentry_version_inc(dentry->d_parent); ovl_dentry_update(dentry, newdentry); ovl_copyattr(newdentry->d_inode, inode); d_instantiate(dentry, inode); newdentry = NULL; out_dput: dput(newdentry); out_unlock: inode_unlock(udir); return err; } Commit Message: ovl: verify upper dentry before unlink and rename Unlink and rename in overlayfs checked the upper dentry for staleness by verifying upper->d_parent against upperdir. However the dentry can go stale also by being unhashed, for example. Expand the verification to actually look up the name again (under parent lock) and check if it matches the upper dentry. This matches what the VFS does before passing the dentry to filesytem's unlink/rename methods, which excludes any inconsistency caused by overlayfs.
