Update strace to 4.18. Noteworthy changes in release 4.18 (2017-07-05) =============================================== * Improvements * Implemented decoding of SCM_TIMESTAMP* control messages. * Implemented decoding of netlink NLMSG_DONE messages. * Implemented decoding of netlink generic nlmsg_type and nlmsg_flags. * Implemented decoding of NETLINK_AUDIT, NETLINK_NETFILTER, NETLINK_ROUTE, NETLINK_SELINUX, NETLINK_SOCK_DIAG, and NETLINK_XFRM message types. * Implemented decoding of NETLINK_GENERIC protocol families. * Implemented basic protocol specific decoding of AF_INET, AF_INET6, AF_NETLINK, AF_PACKET, AF_SMC, and AF_UNIX messages of NETLINK_SOCK_DIAG. * Implemented basic decoding of netlink attributes. * Implemented basic protocol specific decoding of AF_INET, AF_NETLINK, AF_PACKET, AF_SMC, and AF_UNIX netlink attributes of NETLINK_SOCK_DIAG. * Implemented decoding of inet_diag_msg, netlink_diag_msg, and unix_diag_msg netlink attributes of NETLINK_SOCK_DIAG. * Updated lists of ARPHRD_*, KEYCTL_*, NDIAG_SHOW_*, RTM_*, SCM_*, SCTP_*, SO_*, V4L2_*, and prctl ARCH_* constants. * Updated lists of ioctl commands from Linux 4.12. * Bug fixes * In interactive mode (-I2), those signals that were blocked at startup will remain blocked for the whole period of strace execution. * strace no longer resets SIGCHLD handler in tracees to the default action. * When traced command is terminated by a blocked signal, strace unblocks that signal to ensure its own termination with the same signal. * Fixed corner cases in decoding of old sigaction syscall. * Fixed build with old kernel headers on mips. * Fixed build on aarch64 and tile with glibc >= 2.26. * Fixed build on arc and nios2. Bug: N/A Test: strace date Change-Id: Ib34873ff60824b04f67332380c3460721f66002e

Add copyright headers to some files which lack them Before this change, all files that exist since 20th century had copyright headers, while most files that appeared later didn't. This change fixes the inconsistency by adding missing copyright headers. It doesn't mean that copyright headers became maintained. In my view, git history provides much better information on this subject and is much more accurate than copyright headers.

Rewrite signal mask decoding without sigset_t The sigset_t provided by libc is not quite convenient. In glibc, sigset_t is an array with space for 1024 bits, which is much more than required: all architectures supported by Linux have only 64 signals except MIPS, which has 128. In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than necessary. With this change, signal mask is decoded without use of intermediate sigset_t structure, which saves us some cpu cycles in case of glibc with its inflated sigset_t, and enables build with libcs where sigset_t is broken. Old implementation used to check each signal number in the given signal mask twice using sigismember(). New implementation is based on popcount and next_set_bit() so it's noticeably faster. * configure.ac: Check for __builtin_popcount. * signal.c: Ensure that NSIG >= 32. (sprintsigmask, sprintsigmask_long, printsigmask): Remove. (popcount32, sprintsigmask_n): New functions. (tprintsigmask_addr, sprintsigmask_val, tprintsigmask_val): New macros. (print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask, sys_sigsuspend, sys_sigprocmask, decode_new_sigaction): Update to use new signal mask decoding interface. * tests/sigaction.c (main): Add a test with almost filled signal mask. * tests/sigaction.awk: Update.

tests: add a test for rt_sigaction output Since "struct sigaction" varies between architectures, rt_sigaction decoding sometimes produces incorrect output. This test is expected to catch basic rt_sigaction decoding bugs. Based on a patch proposed by Chris Dearman. * tests/sigaction.c: New file. * tests/sigaction.awk: Likewise. * tests/sigaction.sh: New test. * tests/Makefile.am (check_PROGRAMS): Add sigaction. (TESTS): Add sigaction.sh. (EXTRA_DIST): Add sigaction.awk. * tests/.gitignore: Add sigaction.
