| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r290232: Microoptimize. r290231: Addition to prev. commit. In some edge cases fp->_p can be changed in _sseek(), recalculate. r290230: Don't seek to the end if write buffer is empty (in append modes). PR: 204156 r290110: Add _flags2 per jhb@ suggestion since no room left in _flags. Rewrite O_APPEND flag checking using new __S2OAP flag. r289931: According to POSIX, a write operation shall start at the current size of the stream (if mode had 'a' as the first character). r289863: Since no room left in the _flags, reuse __SALC for O_APPEND. It helps to remove _fcntl() call from _ftello() and optimize seek position calculation in _swrite().

* MFC r288430: wordexp: Rewrite to make WRDE_NOCMD reliable.jilles2015-10-252-93/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shell syntax is too complicated to detect command substitution and unquoted operators reliably without implementing much of sh's parser. Therefore, have sh do this detection. While changing sh's support anyway, also read input from a pipe instead of arguments to avoid {ARG_MAX} limits and improve privacy, and output count and length using 16 instead of 8 digits. The basic concept is: execl("/bin/sh", "sh", "-c", "freebsd_wordexp ${1:+\"$1\"} -f "$2", "", flags & WRDE_NOCMD ? "-p" : "", <pipe with words>); The WRDE_BADCHAR error is still implemented in libc. POSIX requires us to fail strings containing unquoted braces with code WRDE_BADCHAR. Since this is normally not a syntax error in sh, there is still a need for checking code in libc, we_check(). The new we_check() is an optimistic check that all the characters <newline> | & ; < > ( ) { } are quoted. To avoid duplicating too much sh logic, such characters are permitted when quoting characters are seen, even if the quoting characters may themselves be quoted. This code reports all WRDE_BADCHAR errors; bad characters that get past it and are a syntax error in sh return WRDE_SYNTAX. Although many implementations of WRDE_NOCMD erroneously allow some command substitutions (and ours even documented this), there appears to be code that relies on its security (codesearch.debian.net shows quite a few uses). Passing untrusted data to wordexp() still exposes a denial of service possibility and a fairly large attack surface. This is also a MFC of r286830 to reduce conflicts. I changed the code somewhat to avoid changes from r286941; in particular, WRDE_BADVAL can still only be returned if WRDE_UNDEF was passed. Relnotes: yes Security: fixes command execution with wordexp(untrusted, WRDE_NOCMD)
* MFC 287386,288949,288993:jhb2015-10-231-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Export current system call code and argument count for system call entry and exit events. To preserve the ABI, the new fields are moved to the end of struct thread in these branches (unlike HEAD) and explicitly copied when new threads are created. In addition, the new tests are only added in 10. r287386: Export current system call code and argument count for system call entry and exit events. procfs stop events for system call tracing report these values (argument count for system call entry and code for system call exit), but ptrace() does not provide this information. (Note that while the system call code can be determined in an ABI-specific manner during system call entry, it is not generally available during system call exit.) The values are exported via new fields at the end of struct ptrace_lwpinfo available via PT_LWPINFO. r288949: Fix various edge cases related to system call tracing. - Always set td_dbg_sc_* when P_TRACED is set on system call entry even if the debugger is not tracing system call entries. This ensures the fields are valid when reporting other stops that occur at system call boundaries such as for PT_FOLLOW_FORKS or when only tracing system call exits. - Set TDB_SCX when reporting the stop for a new child process in fork_return(). This causes the event to be reported as a system call exit. - Report a system call exit event in fork_return() for new threads in a traced process. - Copy td_dbg_sc_* to new threads instead of zeroing. This ensures that td_dbg_sc_code in particular will report the system call that created the new thread or process when it reports a system call exit event in fork_return(). - Add new ptrace tests to verify that new child processes and threads report system call exit events with a valid pl_syscall_code via PT_LWPINFO. r288993: Document the recently added pl_syscall_* fields in struct ptrace_lwpinfo.

| | | | | | | | | | | | | NetBSD commit log: Use a constant array for the MIB. Newer LLVM decided that mib[] warranted stack protections, with the obvious crash after the setup was done. As a positive side effect, code size shrinks a bit. I'm not sure why this hasn't bitten us yes, but it is certainly possible and there are no real drawbacks to this change anyway.
