* MFC r289055 (by mjg@):dchagin2016-01-093-3/+3
| | | | | | | | | | | | | | | | | | | | | | linux: fix handling of out-of-bounds syscall attempts Due to an off by one the code would read an entry past the table, as opposed to the last entry which contains the nosys handler. This fixes my fault. MFC r289058 (by cem@): Fix missing semi-colon from r289055. MFC r289768 (by jhb@): Merge r289055 to amd64/linux32: linux: fix handling of out-of-bounds syscall attempts Due to an off by one the code would read an entry past the table, as opposed to the last entry which contains the nosys handler.
* MFC r288994 (by bdrewery):dchagin2016-01-091-28/+5
| | | | | | | | | | | | | Remove redundant RFFPWAIT/vfork(2) handling in Linux fork(2) and clone(2) wrappers. r161611 added some of the code from sys_vfork() directly into the Linux module wrappers since they use RFSTOPPED. In r232240, the RFFPWAIT handling was moved to syscallret(), thus this code in the Linux module is no longer needed as it will be called later. This also allows the Linux wrappers to benefit from the fix in r275616 for threads not getting suspended if their vforked child is stopped while they wait on them.

* MFC r283569 (by nyan):dchagin2016-01-091-2/+14
| | | | | | | | | | | | | MFi386: r283407 Implement vdso - virtual dynamic shared object. MFi386: r283474 Rework signal code to allow using it by other modules, like linprocfs. MFi386: r283506 For objcopy, use --input-target and --output-target. This fixes pc98 build.
* MFC r283544:dchagin2016-01-093-31/+5
| | | | | | When I merged the lemul branch I missied kib@'s r282708 commit. This is not the final fix as I need properly cleanup thread resources before other threads suicide.
* MFC r283506 (by rodrigc):dchagin2016-01-094-5/+5
| | | | | | | | | For objcopy, use --input-target and --output-target When building with gcc 4.9 and binutils 2.25, using '--input' and '--output' returns an error message: objcopy: option `--input' is ambiguous
* MFC r283498:dchagin2016-01-091-37/+24
| | | | | | | | | | | | | Linux nanosleep() and clock_nanosleep() system calls always writes the remaining time into the structure pointed to by rmtp unless rmtp is NULL. The value of *rmtp can then be used to call nanosleep() again and complete the specified pause if the previous call was interrupted. Note. clock_nanosleep() with an absolute time value does not write the remaining time. While here fix whitespaces and typo in SDT_PROBE.
* MFC r283497:dchagin2016-01-092-1/+18

| | | | | | | The latest cp tool is trying to use the btrfs clone operation that is implemented via ioctl interface. First of all return ENOTSUP for this operation as a cp fallback to usual method in that case. Secondly, do not print out the message about unimplemented operation.

* MFC r283490:dchagin2016-01-091-69/+25
| | | | | Since FreeBSD supports SOCK_CLOEXEC & SOCK_NONBLOCK options remove its emulation via fcntl call from Linuxulator.

* MFC r283483:dchagin2016-01-091-4/+10
| | | | | | Convert signal number to native for VT_SETMODE ioctl and remove strange and invalid ISSIGVALID macro. The code has not been tested right way but it was originally broken.

* MFC r283480:dchagin2016-01-098-6/+90
| | | | Add utimensat() system call.
* MFC r283479:dchagin2016-01-098-50/+0
| | | | | | | | | The kernel sends signals to the processes via ABI specific sv_sendsig method. Native ABI do not need signal conversion, only emulators may want this. Usually emulators implements its own sv_sendsig method. For now only ibcs2 emulator does not have own sv_sendsig implementation and depends on native sendsig() method. So, remove any extra attempts to convert signal numbers from native sendsig() methods except from i386 where ibsc2 is living.
* MFC r283478:dchagin2016-01-091-20/+3
| | | | | Simplify linprocfs_doprocenviron(). Remove extra proc visibility checks and initialize pn_vis by well known procfs_candebug().
* MFC r283476:dchagin2016-01-091-2/+2
| | | | Convert Linux signal number to the FreeBSD.
* MFC r283475:dchagin2016-01-091-16/+14
| | | | | Convert Linux sigsets before showing. Linux kernel displays sigset always as 16x4 bit mask.
* MFC r283474:dchagin2016-01-0920-417/+364
| | | | | | | | | | | | | | | | | | | Rework signal code to allow using it by other modules, like linprocfs: 1. Linux sigset always 64 bit on all platforms. In order to move Linux sigset code to the linux_common module define it as 64 bit int. Move Linux sigset manipulation routines to the MI path. 2. Move Linux signal number definitions to the MI path. In general, they are the same on all platforms except for a few signals. 3. Map Linux RT signals to the FreeBSD RT signals and hide signal conversion tables to avoid conversion errors. 4. Emulate Linux SIGPWR signal via FreeBSD SIGRTMIN signal which is outside of allowed on Linux signal numbers. PR: 197216
* MFC r283473:dchagin2016-01-091-0/+50
| | | | Add support for /proc/<pid>/auxv.
* MFC r283472:dchagin2016-01-091-4/+12
| | | | Add vdso and stack names to the /proc/self/maps.
* MFC r283471:dchagin2016-01-098-79/+28
| | | | | | | | | | | | According to Linux man sigaltstack(3) shall return EINVAL if the ss argument is not a null pointer, and the ss_flags member pointed to by ss contains flags other than SS_DISABLE. However, in fact, Linux also allows SS_ONSTACK flag which is simply ignored. For buggy apps (at least mono) ignore other than SS_DISABLE flags as a Linux do. While here move MI part of sigaltstack code to the appropriate place.
* MFC r283470:dchagin2016-01-092-2/+6
