2016-12-08S3BinaryCacheStore: Ensure it only builds on LinuxEelco Dolstra
2016-12-08Fix S3BinaryCacheStoreEelco Dolstra
It failed with AWS error uploading ‘6gaxphsyhg66mz0a00qghf9nqf7majs2.ls.xz’: Unable to parse ExceptionName: MissingContentLength Message: You must provide the Content-Length HTTP header. possibly because the istringstream_nocopy introduced in 0d2ebb4373e509521f27a6e8f16bfd39d05b2188 doesn't supply the seek method that the AWS library expects. So bring back the old version, but only for S3BinaryCacheStore.

That is, when build-repeat > 0, and the output of two rounds differ, then print a warning rather than fail the build. This is primarily to let Hydra check reproducibility of all packages.

2016-11-16seccomp: Forge return values for *chown32aszlig
These syscalls are only available in 32bit architectures, but libseccomp should handle them correctly even if we're on native architectures that do not have these syscalls. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16seccomp: Forge return codes for POSIX ACL syscallsaszlig
Commands such as "cp -p" also use fsetxattr() in addition to fchown(), so we need to make sure these syscalls always return successful as well in order to avoid nasty "Invalid value" errors. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16release.nix: Add a test for sandboxingaszlig
Right now it only tests whether seccomp correctly forges the return value of chown, but the long-term goal is to test the full sandboxing functionality at some point in the future. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16libstore/build: Forge chown() to return successaszlig
What we basically want is a seccomp mode 2 BPF program like this but for every architecture: BPF_STMT(BPF_LD+BPF_W+BPF_ABS, offsetof(struct seccomp_data, nr)), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_chown, 4, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_fchown, 3, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_fchownat, 2, 0), BPF_JUMP(BPF_JMP+BPF_JEQ+BPF_K, __NR_lchown, 1, 0), BPF_STMT(BPF_RET+BPF_K, SECCOMP_RET_ALLOW), BPF_STMT(BPF_RET+BPF_K, SECCOMP_RET_ERRNO) However, on 32 bit architectures we do have chown32, lchown32 and fchown32, so we'd need to add all the architecture blurb which libseccomp handles for us. So we only need to make sure that we add the 32bit seccomp arch while we're on x86_64 and otherwise we just stay at the native architecture which was set during seccomp_init(), which more or less replicates setting 32bit personality during runChild(). The FORCE_SUCCESS() macro here could be a bit less ugly but I think repeating the seccomp_rule_add() all over the place is way uglier. Another way would have been to create a vector of syscalls to iterate over, but that would make error messages uglier because we can either only print the (libseccomp-internal) syscall number or use seccomp_syscall_resolve_num_arch() to get the name or even make the vector a pair number/name, essentially duplicating everything again. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16Add build dependency for libseccompaszlig
We're going to use libseccomp instead of creating the raw BPF program, because we have different syscall numbers on different architectures. Although our initial seccomp rules will be quite small it really doesn't make sense to generate the raw BPF program because we need to duplicate it and/or make branches on every single architecture we want to suuport. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
2016-11-16Run builds as root in user namespace againaszlig
This reverts commit ff0c0b645cc1448959126185bb2fafe41cf0bddf. We're going to use seccomp to allow "cp -p" and force chown-related syscalls to always return 0. Signed-off-by: aszlig <aszlig@redmoonstudios.org>

2016-11-14daemon: Do not error out when deduplication fails due to ENOSPC.Ludovic Courtès
This solves a problem whereby if /gnu/store/.links had enough entries, ext4's directory index would be full, leading to link(2) returning ENOSPC. * nix/libstore/optimise-store.cc (LocalStore::optimisePath_): Upon ENOSPC from link(2), print a message and return instead of throwing a 'SysError'.
