idr_get_new*() and friends are about to be deprecated. Convert to the new idr_alloc() interface. There are some peculiarities and possible bugs in the converted functions. This patch preserves those. * drv_insert_node_res_element() returns -ENOMEM on alloc failure, -EFAULT if id space is exhausted. -EFAULT is at best misleading. * drv_proc_insert_strm_res_element() is even weirder. It returns -EFAULT if kzalloc() fails, -ENOMEM if idr preloading fails and -EPERM if id space is exhausted. What's going on here? * drv_proc_insert_strm_res_element() doesn't free *pstrm_res after failure. Only compile tested.

由 Kees Cook 提交于
When the new signal handlers are set up, the location of sa_restorer is not cleared, leaking a parent process's address space location to children. This allows for a potential bypass of the parent's ASLR by examining the sa_restorer value returned when calling sigaction(). Based on what should be considered "secret" about addresses, it only matters across the exec not the fork (since the VMAs haven't changed until the exec). But since exec sets SIG_DFL and keeps sa_restorer, this is where it should be fixed. Given the few uses of sa_restorer, a "set" function was not written since this would be the only use. Instead, we use __ARCH_HAS_SA_RESTORER, as already done in other places. Example of the leak before applying this patch: $ cat /proc/$$/maps ... 7fb9f3083000-7fb9f3238000 r-xp 00000000 fd:01 404469 .../libc-2.15.so ... $ ./leak ... 7f278bc74000-7f278be29000 r-xp 00000000 fd:01 404469 .../libc-2.15.so ... 1 0 (nil) 0x7fb9f30b94a0 2 4000000 (nil) 0x7f278bcaa4a0 3 4000000 (nil) 0x7f278bcaa4a0 4 0 (nil) 0x7fb9f30b94a0 ...

Looking at mm/process_vm_access.c:process_vm_rw() and comparing it to compat_process_vm_rw() shows that the compatibility code requires an explicit "access_ok()" check before calling compat_rw_copy_check_uvector(). The same difference seems to appear when we compare fs/read_write.c:do_readv_writev() to fs/compat.c:compat_do_readv_writev(). This subtle difference between the compat and non-compat requirements should probably be debated, as it seems to be error-prone. In fact, there are two others sites that use this function in the Linux kernel, and they both seem to get it wrong: Now shifting our attention to fs/aio.c, we see that aio_setup_iocb() also ends up calling compat_rw_copy_check_uvector() through aio_setup_vectored_rw(). Unfortunately, the access_ok() check appears to be missing. Same situation for security/keys/compat.c:compat_keyctl_instantiate_key_iov(). I propose that we add the access_ok() check directly into compat_rw_copy_check_uvector(), so callers don't have to worry about it, and it therefore makes the compat call code similar to its non-compat counterpart. Place the access_ok() check in the same location where copy_from_user() can trigger a -EFAULT error in the non-compat code, so the ABI behaviors are alike on both compat and non-compat. While we are here, fix compat_do_readv_writev() so it checks for compat_rw_copy_check_uvector() negative return values. And also, fix a memory leak in compat_keyctl_instantiate_key_iov() error handling.

If you open a pipe for neither read nor write, the pipe code will not add any usage counters to the pipe, causing the 'struct pipe_inode_info" to be potentially released early. That doesn't normally matter, since you cannot actually use the pipe, but the pipe release code - particularly fasync handling - still expects the actual pipe infrastructure to all be there. And rather than adding NULL pointer checks, let's just disallow this case, the same way we already do for the named pipe ("fifo") case. This is ancient going back to pre-2.4 days, and until trinity, nobody naver noticed. Reported-by: NDave Jones <davej@redhat.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This fixes CVE-2013-1792. There is a race in install_user_keyrings() that can cause a NULL pointer dereference when called concurrently for the same user if the uid and uid-session keyrings are not yet created. It might be possible for an unprivileged user to trigger this by calling keyctl() from userspace in parallel immediately after logging in. Assume that we have two threads both executing lookup_user_key(), both looking for KEY_SPEC_USER_SESSION_KEYRING. THREAD A THREAD B =============================== =============================== ==>call install_user_keyrings(); if (!cred->user->session_keyring) ==>call install_user_keyrings() ... user->uid_keyring = uid_keyring; if (user->uid_keyring) return 0; <== key = cred->user->session_keyring [== NULL] user->session_keyring = session_keyring; atomic_inc(&key->usage); [oops] At the point thread A dereferences cred->user->session_keyring, thread B hasn't updated user->session_keyring yet, but thread A assumes it is populated because install_user_keyrings() returned ok. The race window is really small but can be exploited if, for example, thread B is interrupted or preempted after initializing uid_keyring, but before doing setting session_keyring. This couldn't be reproduced on a stock kernel. However, after placing systemtap probe on 'user->session_keyring = session_keyring;' that introduced some delay, the kernel could be crashed reliably. Fix this by checking both pointers before deciding whether to return. Alternatively, the test could be done away with entirely as it is checked inside the mutex - but since the mutex is global, that may not be the best way.

Rob Herring has observed that c81611c4 "xen: event channel arrays are xen_ulong_t and not unsigned long" introduced a compile failure when building without CONFIG_AEABI: /tmp/ccJaIZOW.s: Assembler messages: /tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]' Will Deacon pointed out that this is because OABI does not require even base registers for 64-bit values. We can avoid this by simply using the existing atomic64_xchg operation and the same containerof trick as used by the cmpxchg macros. However since this code is used on memory which is shared with the hypervisor we require proper atomic instructions and cannot use the generic atomic64 callbacks (which are based on spinlocks), therefore add a dependency on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much downside to this. While thinking about this we also observed that OABI has different struct alignment requirements to EABI, which is a problem for hypercall argument structs which are shared with the hypervisor and which must be in EABI layout. Since I don't expect people to want to run OABI kernels on Xen depend on CONFIG_AEABI explicitly too (although it also happens to be enforced by the !GENERIC_ATOMIC64 requirement too).

From Zang MingJie. 16) Fix jiffie check in net_rx_action() so that we really cap the processing at 2HZ.

From Gavin Shan and Sathya Perla. 19) Fix TX locking in SFC driver, from Ben Hutchings. 20) Like the VXLAN fix above, when we encap in a TUN device we have to reset the netfilter state. This should fix several strange crashes reported by Dave Jones and others. From Eric Dumazet. 21) Don't forget to clean up MAC address resources when shutting down a port in mlx4 driver, from Yan Burman. 22) Fix divide by zero in vmxnet3 driver, from Bhavesh Davda. 23) Fix device statistic regression in tg3 when the driver is using phylib, from Nithin Sujir. 24) Fix info leak in several netlink handlers, from Mathias Krause. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (79 commits) 6lowpan: Fix endianness issue in is_addr_link_local(). rrunner.c: fix possible memory leak in rr_init_one() dcbnl: fix various netlink info leaks rtnl: fix info leak on RTM_GETLINK request for VF devices bridge: fix mdb info leaks tg3: Update link_up flag for phylib devices ipv6: stop multicast forwarding to process interface scoped addresses bridging: fix rx_handlers return code netlabel: fix build problems when CONFIG_IPV6=n drivers/isdn: checkng length to be sure not memory overflow net/rds: zero last byte for strncpy bnx2x: Fix SFP+ misconfiguration in iSCSI boot scenario bnx2x: Fix intermittent long KR2 link up time macvlan: Set IFF_UNICAST_FLT flag to prevent unnecessary promisc mode. team: unsyc the devices addresses when port is removed bridge: add missing vid to br_mdb_get() Fix: sparse warning in inet_csk_prepare_forced_close afkey: fix a typo MAINTAINERS: Update qlcnic maintainers list netlabel: correctly list all the static label mappings ...
