https://github.com/ojeda/linux Pull compiler attribute updates from Miguel Ojeda: "This is an effort to disentangle the include/linux/compiler*.h headers and bring them up to date. The main idea behind the series is to use feature checking macros (i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION), which are compiler-agnostic (so they can be shared, reducing the size of compiler-specific headers) and version-agnostic. Other related improvements have been performed in the headers as well, which on top of the use of __has_attribute it has amounted to a significant simplification of these headers (e.g. GCC_VERSION is now only guarding a few non-attribute macros). This series should also help the efforts to support compiling the kernel with clang and icc. A fair amount of documentation and comments have also been added, clarified or removed; and the headers are now more readable, which should help kernel developers in general. The series was triggered due to the move to gcc >= 4.6. In turn, this series has also triggered Sparse to gain the ability to recognize __has_attribute on its own. Finally, the __nonstring variable attribute series has been also applied on top; plus two related patches from Nick Desaulniers for unreachable() that came a bit afterwards" * tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux: compiler-gcc: remove comment about gcc 4.5 from unreachable() compiler.h: update definition of unreachable() Compiler Attributes: ext4: remove local __nonstring definition Compiler Attributes: auxdisplay: panel: use __nonstring Compiler Attributes: enable -Wstringop-truncation on W=1 (gcc >= 8) Compiler Attributes: add support for __nonstring (gcc >= 8) Compiler Attributes: add MAINTAINERS entry Compiler Attributes: add Doc/process/programming-language.rst Compiler Attributes: remove uses of __attribute__ from compiler.h Compiler Attributes: KENTRY used twice the "used" attribute Compiler Attributes: use feature checks instead of version checks Compiler Attributes: add missing SPDX ID in compiler_types.h Compiler Attributes: remove unneeded sparse (__CHECKER__) tests Compiler Attributes: homogenize __must_be_array Compiler Attributes: remove unneeded tests Compiler Attributes: always use the extra-underscores syntax Compiler Attributes: remove unused attributes

2018-11-02drm/i915: Configure AUX_CH_CTL when enabling the AUX power domainImre Deak2-8/+47
Most of the AUX_CH_CTL flags are concerned with DP AUX transfer parameters. As opposed to this the flag specifying the thunderbolt vs. non-thunderbolt mode of the port is not related to AUX transfers at all (rather it's repurposed to enable either TBT or non-TBT PHY HW blocks). The programming has to be done before enabling the corresponding AUX power well, so make it part of the power well code. v3: - Use existing enable/disable helpers instead of opencoding. (Jose) - Fix type of is_tc_tbt to remain a bitfield. (Lucas) - Add comment describing the is_tc_tbt power well flag.

2018-11-01of: Fix cpu node iterator to not ignore disabled cpu nodesRob Herring1-2/+0
In most cases, nodes with 'status = "disabled";' are treated as if the node is not present though it is a common bug to forget to check that. However, cpu nodes are different in that "disabled" simply means offline and the OS can bring the CPU core online. Commit f1f207e43b8a ("of: Add cpu node iterator for_each_of_cpu_node()") followed the common behavior of ignoring disabled cpu nodes. This breaks some powerpc systems (at least NXP P50XX/e5500). Fix this by dropping the status check.

2018-11-01net: drop skb on failure in ip_check_defrag()Cong Wang1-4/+8
Most callers of pskb_trim_rcsum() simply drop the skb when it fails, however, ip_check_defrag() still continues to pass the skb up to stack. This is suspicious. In ip_check_defrag(), after we learn the skb is an IP fragment, passing the skb to callers makes no sense, because callers expect fragments are defrag'ed on success. So, dropping the skb when we can't defrag it is reasonable. Note, prior to commit 88078d98d1bb, this is not a big problem as checksum will be fixed up anyway. After it, the checksum is not correct on failure. Found this during code review.

2018-11-01ovl: automatically enable redirect_dir on metacopy=onMiklos Szeredi2-7/+35
Current behavior is to automatically disable metacopy if redirect_dir is not enabled and proceed with the mount. If "metacopy=on" mount option was given, then this behavior can confuse the user: no mount failure, yet metacopy is disabled. This patch makes metacopy=on imply redirect_dir=on. The converse is also true: turning off full redirect with redirect_dir= {off|follow|nofollow} will disable metacopy. If both metacopy=on and redirect_dir={off|follow|nofollow} is specified, then mount will fail, since there's no way to correctly resolve the conflict.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull stackleak gcc plugin from Kees Cook: "Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin was ported from grsecurity by Alexander Popov. It provides efficient stack content poisoning at syscall exit. This creates a defense against at least two classes of flaws: - Uninitialized stack usage. (We continue to work on improving the compiler to do this in other ways: e.g. unconditional zero init was proposed to GCC and Clang, and more plugin work has started too). - Stack content exposure. By greatly reducing the lifetime of valid stack contents, exposures via either direct read bugs or unknown cache side-channels become much more difficult to exploit. This complements the existing buddy and heap poisoning options, but provides the coverage for stacks. The x86 hooks are included in this series (which have been reviewed by Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already been merged through the arm64 tree (written by Laura Abbott and reviewed by Mark Rutland and Will Deacon). With VLAs having been removed this release, there is no need for alloca() protection, so it has been removed from the plugin" * tag 'stackleak-v4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: arm64: Drop unneeded stackleak_check_alloca() stackleak: Allow runtime disabling of kernel stack erasing doc: self-protection: Add information about STACKLEAK feature fs/proc: Show STACKLEAK metrics in the /proc file system lkdtm: Add a test for STACKLEAK gcc-plugins: Add STACKLEAK plugin for tracking the kernel stack x86/entry: Add STACKLEAK erasing the kernel stack at the end of syscalls

2018-11-01SUNRPC: Use atomic(64)_t for seq_send(64)Paul Burton4-39/+16
The seq_send & seq_send64 fields in struct krb5_ctx are used as atomically incrementing counters. This is implemented using cmpxchg() & cmpxchg64() to implement what amount to custom versions of atomic_fetch_inc() & atomic64_fetch_inc(). Besides the duplication, using cmpxchg64() has another major drawback in that some 32 bit architectures don't provide it. As such commit 571ed1fd2390 ("SUNRPC: Replace krb5_seq_lock with a lockless scheme") resulted in build failures for some architectures. Change seq_send to be an atomic_t and seq_send64 to be an atomic64_t, then use atomic(64)_* functions to manipulate the values. The atomic64_t type & associated functions are provided even on architectures which lack real 64 bit atomic memory access via CONFIG_GENERIC_ATOMIC64 which uses spinlocks to serialize access. This fixes the build failures for architectures lacking cmpxchg64(). A potential alternative that was raised would be to provide cmpxchg64() on the 32 bit architectures that currently lack it, using spinlocks. However this would provide a version of cmpxchg64() with semantics a little different to the implementations on architectures with real 64 bit atomics - the spinlock-based implementation would only work if all access to the memory used with cmpxchg64() is *always* performed using cmpxchg64(). That is not currently a requirement for users of cmpxchg64(), and making it one seems questionable. As such avoiding cmpxchg64() outside of architecture-specific code seems best, particularly in cases where atomic64_t seems like a better fit anyway. The CONFIG_GENERIC_ATOMIC64 implementation of atomic64_* functions will use spinlocks & so faces the same issue, but with the key difference that the memory backing an atomic64_t ought to always be accessed via the atomic64_* functions anyway making the issue moot.

2018-11-01perf examples bpf: Start augmenting raw_syscalls:sys_{start,exit}Arnaldo Carvalho de Melo1-0/+59
The previous approach of attaching to each syscall showed how it is possible to augment tracepoints and use that augmentation, pointer payloads, in the existing beautifiers in 'perf trace', but for a more general solution we now will try to augment the main raw_syscalls:sys_{enter,exit} syscalls, and then pass instructions in maps so that it knows which syscalls and which pointer contents, and how many bytes for each of the arguments should be copied. Start with just the bare minimum to collect what is provided by those two tracepoints via the __augmented_syscalls__ map + bpf-output perf event, which results in perf trace showing them without connecting enter+exit: # perf trace -e tools/perf/examples/bpf/augmented_raw_syscalls.c sleep 1 0.000 sleep/11563 raw_syscalls:sys_exit:NR 59 = 0 0.019 ( ): sleep/11563 brk() ... 0.021 sleep/11563 raw_syscalls:sys_exit:NR 12 = 94682642325504 0.033 ( ): sleep/11563 access(filename:, mode: R) ... 0.037 sleep/11563 raw_syscalls:sys_exit:NR 21 = -2 0.041 ( ): sleep/11563 openat(dfd: CWD, filename: , flags: CLOEXEC) ... 0.044 sleep/11563 raw_syscalls:sys_exit:NR 257 = 3 0.045 ( ): sleep/11563 fstat(fd: 3, statbuf: 0x7ffdbf7119b0) ... 0.046 sleep/11563 raw_syscalls:sys_exit:NR 5 = 0 0.047 ( ): sleep/11563 mmap(len: 103334, prot: READ, flags: PRIVATE, fd: 3) ... 0.049 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196285493248 0.050 ( ): sleep/11563 close(fd: 3) ... 0.051 sleep/11563 raw_syscalls:sys_exit:NR 3 = 0 0.059 ( ): sleep/11563 openat(dfd: CWD, filename: , flags: CLOEXEC) ... 0.062 sleep/11563 raw_syscalls:sys_exit:NR 257 = 3 0.063 ( ): sleep/11563 read(fd: 3, buf: 0x7ffdbf711b78, count: 832) ... 0.065 sleep/11563 raw_syscalls:sys_exit:NR 0 = 832 0.066 ( ): sleep/11563 fstat(fd: 3, statbuf: 0x7ffdbf711a10) ... 0.067 sleep/11563 raw_syscalls:sys_exit:NR 5 = 0 0.068 ( ): sleep/11563 mmap(len: 8192, prot: READ|WRITE, flags: PRIVATE|ANONYMOUS) ... 0.070 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196285485056 0.073 ( ): sleep/11563 mmap(len: 3889792, prot: EXEC|READ, flags: PRIVATE|DENYWRITE, fd: 3) ... 0.076 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196279463936 0.077 ( ): sleep/11563 mprotect(start: 0x7f81fd8a8000, len: 2093056) ... 0.083 sleep/11563 raw_syscalls:sys_exit:NR 10 = 0 0.084 ( ): sleep/11563 mmap(addr: 0x7f81fdaa7000, len: 24576, prot: READ|WRITE, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 1753088) ... 0.088 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196283314176 0.091 ( ): sleep/11563 mmap(addr: 0x7f81fdaad000, len: 14976, prot: READ|WRITE, flags: PRIVATE|FIXED|ANONYMOUS) ... 0.093 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196283338752 0.097 ( ): sleep/11563 close(fd: 3) ... 0.098 sleep/11563 raw_syscalls:sys_exit:NR 3 = 0 0.107 ( ): sleep/11563 arch_prctl(option: 4098, arg2: 140196285490432) ... 0.108 sleep/11563 raw_syscalls:sys_exit:NR 158 = 0 0.143 ( ): sleep/11563 mprotect(start: 0x7f81fdaa7000, len: 16384, prot: READ) ... 0.146 sleep/11563 raw_syscalls:sys_exit:NR 10 = 0 0.157 ( ): sleep/11563 mprotect(start: 0x561d037e7000, len: 4096, prot: READ) ... 0.160 sleep/11563 raw_syscalls:sys_exit:NR 10 = 0 0.163 ( ): sleep/11563 mprotect(start: 0x7f81fdcd5000, len: 4096, prot: READ) ... 0.165 sleep/11563 raw_syscalls:sys_exit:NR 10 = 0 0.166 ( ): sleep/11563 munmap(addr: 0x7f81fdcbb000, len: 103334) ... 0.174 sleep/11563 raw_syscalls:sys_exit:NR 11 = 0 0.216 ( ): sleep/11563 brk() ... 0.217 sleep/11563 raw_syscalls:sys_exit:NR 12 = 94682642325504 0.217 ( ): sleep/11563 brk(brk: 0x561d05453000) ... 0.219 sleep/11563 raw_syscalls:sys_exit:NR 12 = 94682642460672 0.220 ( ): sleep/11563 brk() ... 0.221 sleep/11563 raw_syscalls:sys_exit:NR 12 = 94682642460672 0.224 ( ): sleep/11563 open(filename: , flags: CLOEXEC) ... 0.228 sleep/11563 raw_syscalls:sys_exit:NR 2 = 3 0.229 ( ): sleep/11563 fstat(fd: 3, statbuf: 0x7f81fdaacaa0) ... 0.230 sleep/11563 raw_syscalls:sys_exit:NR 5 = 0 0.231 ( ): sleep/11563 mmap(len: 113045344, prot: READ, flags: PRIVATE, fd: 3) ... 0.234 sleep/11563 raw_syscalls:sys_exit:NR 9 = 140196166418432 0.237 ( ): sleep/11563 close(fd: 3) ... 0.238 sleep/11563 raw_syscalls:sys_exit:NR 3 = 0 0.262 ( ): sleep/11563 nanosleep(rqtp: 0x7ffdbf7126f0) ... 1000.399 sleep/11563 raw_syscalls:sys_exit:NR 35 = 0 1000.440 ( ): sleep/11563 close(fd: 1) ... 1000.447 sleep/11563 raw_syscalls:sys_exit:NR 3 = 0 1000.454 ( ): sleep/11563 close(fd: 2) ... 1000.468 ( ): sleep/11563 exit_group( ) # In the next csets we'll connect those events to the existing enter/exit raw_syscalls handlers in 'perf trace', just like we did with the syscalls:sys_{enter,exit}_* tracepoints.
