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().

* Disable SSE in libthrvangyzen2015-10-262-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang emits SSE instructions on amd64 in the common path of pthread_mutex_unlock. If the thread does not otherwise use SSE, this usage incurs a context-switch of the FPU/SSE state, which reduces the performance of multiple real-world applications by a non-trivial amount (3-5% in one application). Instead of this change, I experimented with eagerly switching the FPU state at context-switch time. This did not help. Most of the cost seems to be in the read/write of memory--as kib@ stated--and not in the #NM handling. I tested on machines with and without XSAVEOPT. One counter-argument to this change is that most applications already use SIMD, and the number of applications and amount of SIMD usage are only increasing. This is absolutely true. I agree that--in general and in principle--this change is in the wrong direction. However, there are applications that do not use enough SSE to offset the extra context-switch cost. SSE does not provide a clear benefit in the current libthr code with the current compiler, but it does provide a clear loss in some cases. Therefore, disabling SSE in libthr is a non-loss for most, and a gain for some. I refrained from disabling SSE in libc--as was suggested--because I can't make the above argument for libc. It provides a wide variety of code; each case should be analyzed separately. https://lists.freebsd.org/pipermail/freebsd-current/2015-March/055193.html Suggestions from: dim, jmg, rpaulo Sponsored by: Dell Inc.

* MFC r288309: fnmatch(): Remove exponential behaviour as in sh r229201.jilles2015-10-251-28/+49

* 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)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
