2018-05-11dh key: get rid of stack allocated arrayTycho Andersen1-19/+10
We're interested in getting rid of all of the stack allocated arrays in the kernel: https://lkml.org/lkml/2018/3/7/621 This particular vla is used as a temporary output buffer in case there is too much hash output for the destination buffer. Instead, let's just allocate a buffer that's big enough initially, but only copy back to userspace the amount that was originally asked for. v2: allocate enough in the original output buffer vs creating a temporary output buffer Signed-off-by: Tycho Andersen <tycho@tycho.ws> Reviewed-by: Kees Cook <keescook@chromium.org> CC: David Howells <dhowells@redhat.com> CC: James Morris <jmorris@namei.org> CC: "Serge E.

2018-05-04security: add hook for socketpair()David Herrmann3-0/+20
Right now the LSM labels for socketpairs are always uninitialized, since there is no security hook for the socketpair() syscall. This patch adds the required hooks so LSMs can properly label socketpairs. This allows SO_PEERSEC to return useful information on those sockets. Note that the behavior of socketpair() can be emulated by creating a listener socket, connecting to it, and then discarding the initial listener socket. With this workaround, SO_PEERSEC would return the caller's security context. However, with socketpair(), the uninitialized context is returned unconditionally. This is unexpected and makes socketpair() less useful in situations where the security context is crucial to the application. With the new socketpair-hook this disparity can be solved by making socketpair() return the expected security context.

2018-04-28<linux/stringhash.h>: fix end_name_hash() for 64bit longAmir Goldstein1-2/+2
The comment claims that this helper will try not to loose bits, but for 64bit long it looses the high bits before hashing 64bit long into 32bit int. Use the helper hash_long() to do the right thing for 64bit long. For 32bit long, there is no change. All the callers of end_name_hash() either assign the result to qstr->hash, which is u32 or return the result as an int value (e.g. full_name_hash()). Change the helper return type to int to conform to its users. [ It took me a while to apply this, because my initial reaction to it was - incorrectly - that it could make for slower code. After having looked more at it, I take back all my complaints about the patch, Amir was right and I was mis-reading things or just being stupid. I also don't worry too much about the possible performance impact of this on 64-bit, since most architectures that actually care about performance end up not using this very much (the dcache code is the most performance-critical, but the word-at-a-time case uses its own hashing anyway). So this ends up being mostly used for filesystems that do their own degraded hashing (usually because they want a case-insensitive comparison function). A _tiny_ worry remains, in that not everybody uses DCACHE_WORD_ACCESS, and then this potentially makes things more expensive on 64-bit architectures with slow or lacking multipliers even for the normal case. That said, realistically the only such architecture I can think of is PA-RISC. Nobody really cares about performance on that, it's more of a "look ma, I've got warts^W an odd machine" platform. So the patch is fine, and all my initial worries were just misplaced from not looking at this properly. - Linus ] Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-04-27kvm: apic: Flush TLB after APIC mode/address change if VPIDs are in useJunaid Shahid1-10/+4
Currently, KVM flushes the TLB after a change to the APIC access page address or the APIC mode when EPT mode is enabled. However, even in shadow paging mode, a TLB flush is needed if VPIDs are being used, as specified in the Intel SDM Section 29.4.5. So replace vmx_flush_tlb_ept_only() with vmx_flush_tlb(), which will flush if either EPT or VPIDs are in use.

2018-04-27x86/entry/64/compat: Preserve r8-r11 in int $0x80Andy Lutomirski2-18/+25
32-bit user code that uses int $80 doesn't care about r8-r11. There is, however, some 64-bit user code that intentionally uses int $0x80 to invoke 32-bit system calls. From what I've seen, basically all such code assumes that r8-r15 are all preserved, but the kernel clobbers r8-r11. Since I doubt that there's any code that depends on int $0x80 zeroing r8-r11, change the kernel to preserve them. I suspect that very little user code is broken by the old clobber, since r8-r11 are only rarely allocated by gcc, and they're clobbered by function calls, so they only way we'd see a problem is if the same function that invokes int $0x80 also spills something important to one of these registers. The current behavior seems to date back to the historical commit "[PATCH] x86-64 merge for 2.6.4". Before that, all regs were preserved. I can't find any explanation of why this change was made. Update the test_syscall_vdso_32 testcase as well to verify the new behavior, and it strengthens the test to make sure that the kernel doesn't accidentally permute r8..r15.

2018-04-27x86/ipc: Fix x32 version of shmid64_ds and msqid64_dsArnd Bergmann2-0/+73
A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout (as seen from user space) a few years ago: Originally, __BITS_PER_LONG was defined as 64 on x32, so we did not have padding after the 64-bit __kernel_time_t fields, After __BITS_PER_LONG got changed to 32, applications would observe extra padding. In other parts of the uapi headers we seem to have a mix of those expecting either 32 or 64 on x32 applications, so we can't easily revert the path that broke these two structures. Instead, this patch decouples x32 from the other architectures and moves it back into arch specific headers, partially reverting the even older commit 73a2d096fdf2 ("x86: remove all now-duplicate header files"). It's not clear whether this ever made any difference, since at least glibc carries its own (correct) copy of both of these header files, so possibly no application has ever observed the definitions here. Based on a suggestion from H.J. Lu, I tried out the tool from https://github.com/hjl-tools/linux-header to find other such bugs, which pointed out the same bug in statfs(), which also has a separate (correct) copy in glibc.

2018-04-27x86/setup: Do not reserve a crash kernel region if booted on Xen PVPetr Tesarik1-0/+6
Xen PV domains cannot shut down and start a crash kernel. Instead, the crashing kernel makes a SCHEDOP_shutdown hypercall with the reason code SHUTDOWN_crash, cf. xen_crash_shutdown() machine op in arch/x86/xen/enlighten_pv.c. A crash kernel reservation is merely a waste of RAM in this case. It may also confuse users of kexec_load(2) and/or kexec_file_load(2). When flags include KEXEC_ON_CRASH or KEXEC_FILE_ON_CRASH, respectively, these syscalls return success, which is technically correct, but the crash kexec image will never be actually used.

2018-04-27arm64: avoid instrumenting atomic_ll_sc.oMark Rutland1-0/+4
Our out-of-line atomics are built with a special calling convention, preventing pointless stack spilling, and allowing us to patch call sites with ARMv8.1 atomic instructions. Instrumentation inserted by the compiler may result in calls to functions not following this special calling convention, resulting in registers being unexpectedly clobbered, and various problems resulting from this. For example, if a kernel is built with KCOV and ARM64_LSE_ATOMICS, the compiler inserts calls to __sanitizer_cov_trace_pc in the prologues of the atomic functions. This has been observed to result in spurious cmpxchg failures, leading to a hang early on in the boot process. This patch avoids such issues by preventing instrumentation of our out-of-line atomics.

2018-04-27powerpc: Fix deadlock with multiple calls to smp_send_stopNicholas Piggin1-16/+39
smp_send_stop can lock up the IPI path for any subsequent calls, because the receiving CPUs spin in their handler function. This started becoming a problem with the addition of an smp_send_stop call in the reboot path, because panics can reboot after doing their own smp_send_stop. The NMI IPI variant was fixed with ac61c11566 ("powerpc: Fix smp_send_stop NMI IPI handling"), which leaves the smp_call_function variant. This is fixed by having smp_send_stop only ever do the smp_call_function once. This is a bit less robust than the NMI IPI fix, because any other call to smp_call_function after smp_send_stop could deadlock, but that has always been the case, and it was not been a problem before.

We can ensure that the timer always runs on one of the policy-cpus. If the timer gets migrated to a cpu outside the policy then re-queue it back on the policy->cpus. This way we can get rid of the smp-call which was being used to set the pstate on the policy->cpus.
