commit 0185604c upstream. Currently if userspace restores the pit counters with a count of 0 on channels 1 or 2 and the guest attempts to read the count on those channels, then KVM will perform a mod of 0 and crash. This will ensure that 0 values are converted to 65536 as per the spec. This is CVE-2015-7513. Signed-off-by:

commit b4a1b4f5 upstream. This fixes CVE-2015-7550. There's a race between keyctl_read() and keyctl_revoke(). If the revoke happens between keyctl_read() checking the validity of a key and the key's semaphore being taken, then the key type read method will see a revoked key. This causes a problem for the user-defined key type because it assumes in its read method that there will always be a payload in a non-revoked key and doesn't check for a NULL pointer. Fix this by making keyctl_read() check the validity of a key after taking semaphore instead of before. I think the bug was introduced with the original keyrings code. This was discovered by a multithreaded test program generated by syzkaller (http://github.com/google/syzkaller). Here's a cleaned up version: #include <sys/types.h> #include <keyutils.h> #include <pthread.h> void *thr0(void *arg) { key_serial_t key = (unsigned long)arg; keyctl_revoke(key); return 0; } void *thr1(void *arg) { key_serial_t key = (unsigned long)arg; char buffer[16]; keyctl_read(key, buffer, 16); return 0; } int main() { key_serial_t key = add_key("user", "%", "foo", 3, KEY_SPEC_USER_KEYRING); pthread_t th[5]; pthread_create(&th[0], 0, thr0, (void *)(unsigned long)key); pthread_create(&th[1], 0, thr1, (void *)(unsigned long)key); pthread_create(&th[2], 0, thr0, (void *)(unsigned long)key); pthread_create(&th[3], 0, thr1, (void *)(unsigned long)key); pthread_join(th[0], 0); pthread_join(th[1], 0); pthread_join(th[2], 0); pthread_join(th[3], 0); return 0; } Build as: cc -o keyctl-race keyctl-race.c -lkeyutils -lpthread Run as: while keyctl-race; do :; done as it may need several iterations to crash the kernel. The crash can be summarised as: BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 IP: [<ffffffff81279b08>] user_read+0x56/0xa3 ...

[ Upstream commit c6ff5268 ] The commit ba7c95ea ("rhashtable: Fix sleeping inside RCU critical section in walk_stop") introduced a new spinlock for the walker list. However, it did not convert all existing users of the list over to the new spin lock. Some continued to use the old mutext for this purpose. This obviously led to corruption of the list. The fix is to use the spin lock everywhere where we touch the list. This also allows us to do rcu_rad_lock before we take the lock in rhashtable_walk_start. With the old mutex this would've deadlocked but it's safe with the new spin lock. Fixes: ba7c95ea ("rhashtable: Fix sleeping inside RCU...") Reported-by:

[ Upstream commit 3822b5c2 ] With b3ca9b02, the AF_UNIX SOCK_STREAM receive code was changed from using mutex_lock(&u->readlock) to mutex_lock_interruptible(&u->readlock) to prevent signals from being delayed for an indefinite time if a thread sleeping on the mutex happened to be selected for handling the signal. But this was never a problem with the stream receive code (as opposed to its datagram counterpart) as that never went to sleep waiting for new messages with the mutex held and thus, wouldn't cause secondary readers to block on the mutex waiting for the sleeping primary reader. As the interruptible locking makes the code more complicated in exchange for no benefit, change it back to using mutex_lock. Signed-off-by:

[ Upstream commit 7bff47da ] After commit 15bf176d ("gianfar: Don't enable the Filer w/o the Parser"), 'TSEC' model controllers (for example as seen on MPC8541E) always have 8 bytes stripped from the front of received frames. Only 'eTSEC' gianfar controllers have the RX Filer capability (amongst other enhancements). Previously this was treated as always enabled for both 'TSEC' and 'eTSEC' controllers. In commit 15bf176d ("gianfar: Don't enable the Filer w/o the Parser") a subtle change was made to the setting of 'uses_rxfcb' to effectively always set it (since 'rx_filer_enable' was always true). This had the side-effect of always stripping 8 bytes from the front of received frames on 'TSEC' type controllers. We now only enable the RX Filer capability on controller types that support it, thereby avoiding the issue for 'TSEC' type controllers. Reviewed-by:

[ Upstream commit a6e18ff1 ] When we have multiple stacked vlan devices all of which have turned off REORDER_HEADER flag, the untag operation does not locate the ethernet addresses correctly for nested vlans. The reason is that in case of REORDER_HEADER flag being off, the outer vlan headers are put back and the mac_len is adjusted to account for the presense of the header. Then, the subsequent untag operation, for the next level vlan, always use VLAN_ETH_HLEN to locate the begining of the ethernet header and that ends up being a multiple of 4 bytes short of the actuall beginning of the mac header (the multiple depending on the how many vlan encapsulations ethere are). As a reslult, if there are multiple levles of vlan devices with REODER_HEADER being off, the recevied packets end up being dropped. To solve this, we use skb->mac_len as the offset. The value is always set on receive path and starts out as a ETH_HLEN. The value is also updated when the vlan header manupations occur so we know it will be correct. Signed-off-by:

[ Upstream commit 5037e9ef ] David Wilder reported crashes caused by dst reuse. <quote David> I am seeing a crash on a distro V4.2.3 kernel caused by a double release of a dst_entry. In ipv4_dst_destroy() the call to list_empty() finds a poisoned next pointer, indicating the dst_entry has already been removed from the list and freed. The crash occurs 18 to 24 hours into a run of a network stress exerciser. </quote> Thanks to his detailed report and analysis, we were able to understand the core issue. IP early demux can associate a dst to skb, after a lookup in TCP/UDP sockets. When socket cache is not properly set, we want to store into sk->sk_dst_cache the dst for future IP early demux lookups, by acquiring a stable refcount on the dst. Problem is this acquisition is simply using an atomic_inc(), which works well, unless the dst was queued for destruction from dst_release() noticing dst refcount went to zero, if DST_NOCACHE was set on dst. We need to make sure current refcount is not zero before incrementing it, or risk double free as David reported. This patch, being a stable candidate, adds two new helpers, and use them only from IP early demux problematic paths. It might be possible to merge in net-next skb_dst_force() and skb_dst_force_safe(), but I prefer having the smallest patch for stable kernels : Maybe some skb_dst_force() callers do not expect skb->dst can suddenly be cleared. Can probably be backported back to linux-3.6 kernels Reported-by:

[ Upstream commit 79462ad0 ] 郭永刚 reported that one could simply crash the kernel as root by using a simple program: int socket_fd; struct sockaddr_in addr; addr.sin_port = 0; addr.sin_addr.s_addr = INADDR_ANY; addr.sin_family = 10; socket_fd = socket(10,3,0x40000000); connect(socket_fd , &addr,16); AF_INET, AF_INET6 sockets actually only support 8-bit protocol identifiers. inet_sock's skc_protocol field thus is sized accordingly, thus larger protocol identifiers simply cut off the higher bits and store a zero in the protocol fields. This could lead to e.g. NULL function pointer because as a result of the cut off inet_num is zero and we call down to inet_autobind, which is NULL for raw sockets. kernel: Call Trace: kernel: [<ffffffff816db90e>] ? inet_autobind+0x2e/0x70 kernel: [<ffffffff816db9a4>] inet_dgram_connect+0x54/0x80 kernel: [<ffffffff81645069>] SYSC_connect+0xd9/0x110 kernel: [<ffffffff810ac51b>] ? ptrace_notify+0x5b/0x80 kernel: [<ffffffff810236d8>] ? syscall_trace_enter_phase2+0x108/0x200 kernel: [<ffffffff81645e0e>] SyS_connect+0xe/0x10 kernel: [<ffffffff81779515>] tracesys_phase2+0x84/0x89 I found no particular commit which introduced this problem.

[ Upstream commit 90186af4 ] When an interface is brought up which was previously suspended (via runtime PM), it would hang. This happens because napi_disable is called before napi_enable. Solve this by avoiding napi_enable in the resume during open function (netif_running is true when open is called, IFF_UP is set after a successful open; netif_running is false when close is called, but IFF_UP is then still set). While at it, remove WORK_ENABLE check from rtl8152_open (introduced with the original change) because it cannot happen: - After this patch, runtime resume will not set it during rtl8152_open. - When link is up, rtl8152_open is not called. - When link is down during system/auto suspend/resume, it is not set.

commit aed335ee upstream. The DELL PERC5 controller firmware does not list tape drives in response to MR_DCMD_PD_LIST_QUERY. This causes tape drives not be exposed to the OS when connected to a PERC5 controller. This patch permits detection of tape drives connected to a PERC5 controller by exposing non-TYPE_DISK devices unconditionally. Signed-off-by:

commit eb8ed1eb upstream. Reference to the 'np' node is dropped before dereferencing the 'sizep' and 'basep' pointers, which could by then point to junk if the node has been freed. Refactor code to call 'of_node_put' later. Fixes: c5df3926 ("drivers/char/tpm: Add securityfs support for event log") Signed-off-by:

commit 4bed5395 upstream. The fixed_phy infrastructure is done in a way that is optional, by providing 'static inline' helper functions doing nothing in include/linux/phy_fixed.h for all its APIs. However, three out of the four users (DSA, BCMGENET, and SYSTEMPORT) always 'select FIXED_PHY', presumably because they need that. MVNETA is the fourth one, and if that is built-in but FIXED_PHY is configured as a loadable module, we get a link error: drivers/built-in.o: In function `mvneta_fixed_link_update': fpga-mgr.c:(.text+0x33ed80): undefined reference to `fixed_phy_update_state' Presumably this driver has the same dependency as the others, so this patch also uses 'select' to ensure that the fixed-phy support is built-in.
