* uapi glibc compat: fix compile errors when glibc net/if.h included before ↵Mikko Rapeli2016-05-102-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | linux/if.h glibc's net/if.h contains copies of definitions from linux/if.h and these conflict and cause build failures if both files are included by application source code. Changes in uapi headers, which fixed header file dependencies to include linux/if.h when it was needed, e.g. commit 1ffad83d, made the net/if.h and linux/if.h incompatibilities visible as build failures for userspace applications like iproute2 and xtables-addons. This patch fixes compile errors when glibc net/if.h is included before linux/if.h: ./linux/if.h:99:21: error: redeclaration of enumerator ‘IFF_NOARP’ ./linux/if.h:98:23: error: redeclaration of enumerator ‘IFF_RUNNING’ ./linux/if.h:97:26: error: redeclaration of enumerator ‘IFF_NOTRAILERS’ ./linux/if.h:96:27: error: redeclaration of enumerator ‘IFF_POINTOPOINT’ ./linux/if.h:95:24: error: redeclaration of enumerator ‘IFF_LOOPBACK’ ./linux/if.h:94:21: error: redeclaration of enumerator ‘IFF_DEBUG’ ./linux/if.h:93:25: error: redeclaration of enumerator ‘IFF_BROADCAST’ ./linux/if.h:92:19: error: redeclaration of enumerator ‘IFF_UP’ ./linux/if.h:252:8: error: redefinition of ‘struct ifconf’ ./linux/if.h:203:8: error: redefinition of ‘struct ifreq’ ./linux/if.h:169:8: error: redefinition of ‘struct ifmap’ ./linux/if.h:107:23: error: redeclaration of enumerator ‘IFF_DYNAMIC’ ./linux/if.h:106:25: error: redeclaration of enumerator ‘IFF_AUTOMEDIA’ ./linux/if.h:105:23: error: redeclaration of enumerator ‘IFF_PORTSEL’ ./linux/if.h:104:25: error: redeclaration of enumerator ‘IFF_MULTICAST’ ./linux/if.h:103:21: error: redeclaration of enumerator ‘IFF_SLAVE’ ./linux/if.h:102:22: error: redeclaration of enumerator ‘IFF_MASTER’ ./linux/if.h:101:24: error: redeclaration of enumerator ‘IFF_ALLMULTI’ ./linux/if.h:100:23: error: redeclaration of enumerator ‘IFF_PROMISC’ The cases where linux/if.h is included before net/if.h need a similar fix in the glibc side, or the order of include files can be changed userspace code as a workaround.

| * | byteswap: try to avoid __builtin_constant_p gcc bugArnd Bergmann2016-05-061-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is another attempt to avoid a regression in wwn_to_u64() after that started using get_unaligned_be64(), which in turn ran into a bug on gcc-4.9 through 6.1. The regression got introduced due to the combination of two separate workarounds (commits e3bde9568d99: "include/linux/unaligned: force inlining of byteswap operations" and ef3fb2422ffe: "scsi: fc: use get/put_unaligned64 for wwn access") that each try to sidestep distinct problems with gcc behavior (code growth and increased stack usage). Unfortunately after both have been applied, a more serious gcc bug has been uncovered, leading to incorrect object code that discards part of a function and causes undefined behavior. As part of this problem is how __builtin_constant_p gets evaluated on an argument passed by reference into an inline function, this avoids the use of __builtin_constant_p() for all architectures that set CONFIG_ARCH_USE_BUILTIN_BSWAP. Most architectures do not set ARCH_SUPPORTS_OPTIMIZED_INLINING, which means they probably do not suffer from the problem in the qla2xxx driver, but they might still run into it elsewhere. Both of the original workarounds were only merged in the 4.6 kernel, and the bug that is fixed by this patch should only appear if both are there, so we probably don't need to backport the fix. On the other hand, it works by simplifying the code path and should not have any negative effects.

This fixes the table to use the correct compat syscalls, like the other 64-bit architectures do.

This patch defines the device status bit in the uapi header file so that both the kernel and userspace applications can use it. The bit is currently unused by the virtio guest drivers and vhost. According to the spec "a good implementation will try to recover by issuing a reset". This is not attempted here because it requires auditing the virtio drivers to ensure there are no resource leaks or crashes if the device needs to be reset mid-operation.

|/ | | | | | | | | | | | | | | | | | Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl and tunnel_label members explicit. No issue has been observed, and gcc/llvm does padding for the old struct already, where tunnel_label was not yet present, so the current code works, but since it's part of uapi, make sure we don't introduce holes in structs. Therefore, add tunnel_ext that we can use generically in future (f.e. to flag OAM messages for backends, etc). Also add the offset to the compat tests to be sure should some compilers not padd the tail of the old version of bpf_tunnel_key.

Coverage-guided fuzzing is a testing technique that uses coverage feedback to determine new interesting inputs to a system. A notable user-space example is AFL (http://lcamtuf.coredump.cx/afl/). However, this technique is not widely used for kernel testing due to missing compiler and kernel support. kcov does not aim to collect as much coverage as possible. It aims to collect more or less stable coverage that is function of syscall inputs. To achieve this goal it does not collect coverage in soft/hard interrupts and instrumentation of some inherently non-deterministic or non-interesting parts of kernel is disbled (e.g. scheduler, locking). Currently there is a single coverage collection mode (tracing), but the API anticipates additional collection modes. Initially I also implemented a second mode which exposes coverage in a fixed-size hash table of counters (what Quentin used in his original patch). I've dropped the second mode for simplicity. This patch adds the necessary support on kernel side. The complimentary compiler support was added in gcc revision 231296. We've used this support to build syzkaller system call fuzzer, which has found 90 kernel bugs in just 2 months: https://github.com/google/syzkaller/wiki/Found-Bugs We've also found 30+ bugs in our internal systems with syzkaller. Another (yet unexplored) direction where kcov coverage would greatly help is more traditional "blob mutation". For example, mounting a random blob as a filesystem, or receiving a random blob over wire. Why not gcov. Typical fuzzing loop looks as follows: (1) reset coverage, (2) execute a bit of code, (3) collect coverage, repeat. A typical coverage can be just a dozen of basic blocks (e.g. an invalid input). In such context gcov becomes prohibitively expensive as reset/collect coverage steps depend on total number of basic blocks/edges in program (in case of kernel it is about 2M). Cost of kcov depends only on number of executed basic blocks/edges. On top of that, kernel requires per-thread coverage because there are always background threads and unrelated processes that also produce coverage. With inlined gcov instrumentation per-thread coverage is not possible. kcov exposes kernel PCs and control flow to user-space which is insecure. But debugfs should not be mapped as user accessible. Based on a patch by Quentin Casasnovas.

This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to.

Due to difference in operation and information, the tracing functions related to expected receives had to be changed. This patch include these changes. The tracing function changes could not be split into a separate commit without including both tracing variants at the same time. This would have caused other complications and ugliness.

This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

The reason that removed DRM_EXYNOS_GEM_MAP_OFFSET was we could use DRM_IOCTL_MODE_MAP_DUMB. Both did exactly same thing. Now we again will revive it as DRM_EXYNOS_GEM_MAP because of render node.

Note: currently only supported on a4xx.. a3xx doesn't have this always-on counter. I think we could emulate it with the one CP counter that is available, but for now it is of limited usefulness on a3xx (since we can't seem to do time-elapsed queries in any sane way with the existing firmware on a3xx, and if you are trying to do profiling on a tiler you want time-elapsed). We can add that later if it becomes useful. Signed-off-by: Rob Clark <robdclark@gmail.com>
