MFC r258537, r258587:
r258537 (hrs): Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns EILSEQ when there is an invalid character in the output codeset while it is valid in the input. However, POSIX requires iconv() to perform an implementation-defined conversion on the character. So, Citrus iconv converts such a character to a special character which means it is invalid in the output codeset.
This is not a problem in most cases but some software like libxml2 depends on GNU's behavior to determine if a character is output as-is or another form such as a character entity (&#NNN;).
r258587 (peter): Move the iconv wrapper source from libc_nonshared to libc/iconv so that it is all in the one place again. Rename libc/iconv/iconv.c to bsd_iconv.c. Compile the wrappers into libc.a so that WITHOUT_DYNAMICROOT works again.

Change the cap_rights_t type from uint64_t to a structure that we can extend in the future in a backward compatible (API and ABI) way.
The cap_rights_t represents capability rights. We used to use one bit to represent one right, but we are running out of spare bits. Currently the new structure provides place for 114 rights (so 50 more than the previous cap_rights_t), but it is possible to grow the structure to hold at least 285 rights, although we can make it even larger if 285 rights won't be enough.
The structure definition looks like this:
struct cap_rights { uint64_t cr_rights[CAP_RIGHTS_VERSION + 2]; };
The initial CAP_RIGHTS_VERSION is 0.
The top two bits in the first element of the cr_rights[] array contain total number of elements in the array - 2. This means if those two bits are equal to 0, we have 2 array elements.
The top two bits in all remaining array elements should be 0. The next five bits in all array elements contain array index. Only one bit is used and bit position in this five-bits range defines array index. This means there can be at most five array elements in the future.
To define new right the CAPRIGHT() macro must be used. The macro takes two arguments - an array index and a bit to set, eg.
#define CAP_PDKILL CAPRIGHT(1, 0x0000000000000800ULL)
We still support aliases that combine few rights, but the rights have to belong to the same array element, eg:
#define CAP_LOOKUP CAPRIGHT(0, 0x0000000000000400ULL) #define CAP_FCHMOD CAPRIGHT(0, 0x0000000000002000ULL)
#define CAP_FCHMODAT (CAP_FCHMOD | CAP_LOOKUP)
There is new API to manage the new cap_rights_t structure:
cap_rights_t *cap_rights_init(cap_rights_t *rights, ...); void cap_rights_set(cap_rights_t *rights, ...); void cap_rights_clear(cap_rights_t *rights, ...); bool cap_rights_is_set(const cap_rights_t *rights, ...);
bool cap_rights_is_valid(const cap_rights_t *rights); void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src); void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src); bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little);
Capability rights to the cap_rights_init(), cap_rights_set(), cap_rights_clear() and cap_rights_is_set() functions are provided by separating them with commas, eg:
cap_rights_t rights;
cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT);
There is no need to terminate the list of rights, as those functions are actually macros that take care of the termination, eg:
#define cap_rights_set(rights, ...) \ __cap_rights_set((rights), __VA_ARGS__, 0ULL) void __cap_rights_set(cap_rights_t *rights, ...);
Thanks to using one bit as an array index we can assert in those functions that there are no two rights belonging to different array elements provided together. For example this is illegal and will be detected, because CAP_LOOKUP belongs to element 0 and CAP_PDKILL to element 1:
cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL);
Providing several rights that belongs to the same array's element this way is correct, but is not advised. It should only be used for aliases definition.
This commit also breaks compatibility with some existing Capsicum system calls, but I see no other way to do that. This should be fine as Capsicum is still experimental and this change is not going to 9.x.

Turn libc.so into an ld script rather than a symlink pointing to the real shared object and libssp_nonshared.a.
This was the last showstopper that prevented from enabling SSP for ports by default. portmgr@ performed a buildworld which showed no significant breakage with this patch.
Details:
On i386 for PIC objects, gcc uses the __stack_chk_fail_local hidden symbol instead of calling __stack_chk_fail directly [1]. This happen not only with our gcc-4.2.1 but also with the latest gcc-4.8. If you want the very nasty details, see [2].
OTOH the problem doesn't exist on other architectures. It also doesn't exist with Clang as the latter will somehow manage to create the function in the object file at compile time (contrary to only referencing it through a symbol that will be brought in at link time).
In a perfect world, when an object file is compiled with -fstack-protector, it will be linked into a binary or a DSO with this same flag as well, so GCC will add libssp_nonshared.a to the linker command-line. Unfortunately, we don't control softwares in ports and we may have such broken DSO. This is the whole point of this patch.
You can reproduce the problem on i386 by compiling a source file into an object file with "-fstack-protector-all -fPIE" and linking it into a binary without "-fstack-protector".
This ld script automatically proposes libssp_nonshared.a along with the real libc DSO to the linker. It is important to understand that the object file contained in this library will be pulled in the resulting binary _only if_ the linker notices one of its symbols is needed (i.e. one of the SSP symbol is missing).
A theorical performance impact could be when compiling, but my testing showed less than 0.1% of difference.
[1] For 32-bit code gcc saves the PIC register setup by using __stack_chk_fail_local hidden function instead of calling __stack_chk_fail directly. See comment line 19460 in: src/contrib/gcc/config/i386/i386.c
[2] When compiling a source file to an object file, if you use something which is external to the compilation unit, GCC doesn't know yet if this symbol will be inside or outside the DSO. So it expects the worst case and routes the symbol through the GOT, which means additional space and extra relocation for rtld(1).
Declaring a symbol has hidden tells GCC to use the optimal route (no GOT), but on the other hand this means the symbol has to be provided in the same DSO (namely libssp_nonshared.a).
On i386, GCC actually uses an hidden symbol for SSP in PIC objects to save PIC register setup, as said in [1].

Merge index() and strchr() together.
As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead.
Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications.
Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr().
This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

Add the BSD-licensed Citrus iconv to the base system with default off setting. It can be built by setting the WITH_ICONV knob. While this knob is unset, the library part, the binaries, the header file and the metadata files will not be built or installed so it makes no impact on the system if left turned off.
This work is based on the iconv implementation in NetBSD but a great number of improvements and feature additions have been included:
- Some utilities have been added. There is a conversion table generator, which can compare conversion tables to reference data generated by GNU libiconv. This helps ensuring conversion compatibility. - UTF-16 surrogate support and some endianness issues have been fixed. - The rather chaotic Makefiles to build metadata have been refactored and cleaned up, now it is easy to read and it is also easier to add support for new encodings. - A bunch of new encodings and encoding aliases have been added. - Support for 1->2, 1->3 and 1->4 mappings, which is needed for transliterating with flying accents as GNU does, like "u. - Lots of warnings have been fixed, the major part of the code is now WARNS=6 clean. - New section 1 and section 5 manual pages have been added. - Some GNU-specific calls have been implemented: iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into() - Support for GNU's //IGNORE suffix has been added. - The "-" argument for stdin is now recognized in iconv(1) as per POSIX. - The Big5 conversion module has been fixed. - The iconv.h header files is supposed to be compatible with the GNU version, i.e. sources should build with base iconv.h and GNU libiconv. It also includes a macro magic to deal with the char ** and const char ** incompatibility. - GNU compatibility: "" or "char" means the current local encoding in use - Various cleanups and style(9) fixes.

Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces MACHINE_ARCH=mipse[lb] TARGET_ABI=n64.
MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working cases, I've kept it in for now.
Added mips64e[lb] to make universe, so more kernels build.

Enable GCC stack protection (aka Propolice) for userland: - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64.

Update the resolver in libc to BIND9's one.
Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc.
Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them).
Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe.

Stage 3 of dynamic root support. Make all the libraries needed to run binaries in /bin and /sbin installed in /lib. Only the versioned files reside in /lib, the .so symlink continues to live /usr/lib so the toolchain doesn't need to be modified.

Replace our ancient dtoa/strtod implementation with the gdtoa package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now.
As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

Implement fpclassify(): o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to <machine/_types.h>, and provide double_t and float_t typedefs in <math.h>. o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via <machine/float.h>. o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'.
This was developed by David Schultz and myself with input from bde and fenner.

Rip out the old __stdin/out/err stuff. It was completely 100% useless. :-( It was foiled because of dynamic copy relocations that caused compile-time space to be reserved in .bss and at run time a blob of data was copied to that space and everything used the .bss version.. The problem is that the space is reserved at compile time, not runtime... So we *still* could not change the size of FILE. Sigh. :-(
Replace it with something that does actually work and really does let us make 'FILE' extendable. It also happens to be the same as Linux does in glibc, but has the slight cost of a pointer. Note that this is the same cost that 'fp = fopen(), fprintf(fp, ...); fclose(fp);' has. Fortunately, actual references to stdin/out/err are not all that common since we have implicit stdin/out/err-using versions of functions (printf() vs. fprintf()).

Fix the current libc breakage in current: o Back out the __std* stuff. Can't figure out how to do this right now, so we'll save it for late. o use _up as a pointer for extra fields that we need to access. o back out the libc major version bump.
Submitted by: green reviewed by: peter, imp, green, obrien (to varying degrees).
We'll fix the "how do we stop encoding sizeof(FILE) in binaries" part later.

Commit a libc fix going by the current state of the version numbering bikeshed in -arch. It isn't quite over, but it has been well established that this can be adjusted or refined. But we do seem to have consensis on a major bump of some sort. After this, it should reasonably safe to build world again.
This change is to get rid of __sF[] and use seperate __stdin/out/err handles. This means we can pad on extra bits onto the end of FILE at will without going through this all over again. __sF[] was evil because it compiled the sizeof(FILE) into every stdio using program.

Clean up syscall generation in libc by removing HIDDEN_SYSCALLS and treating (almost) all system calls the same way:
__sys_foo - actual syscall foo, _foo - weak definitions to __sys_foo
Change PSEUDO syscalls (currently only _exit and _getlogin) to be __sys_foo (T) and _foo (W).
Add $FreeBSD$ to a few files to satisfy commitprep.

Remove _THREAD_SAFE and make libc thread-safe by default by adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in.
Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo
Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo.
Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible.
Remove uneeded includes of <errno.h> from a few files.
Add $FreeBSD$ to a few files in order to pass commitprep.

sigset_t change (part 5 of 5) -----------------------------
Most of the userland changes are in libc. For both the alpha and the i386 setjmp has been changed to accomodate for the new sigset_t. Internally, libc is mostly rewritten to use the new syscalls. The exception is in compat-43/sigcompat.c
The POSIX thread library has also been rewritten to use the new sigset_t. Except, that it currently only handles NSIG signals instead of the maximum _SIG_MAXSIG. This should not be a problem because current applications don't use any signals higher than NSIG.
There are version bumps for the following libraries: libdialog libreadline libc libc_r libedit libftpio libss
These libraries either a) have one of the modified structures visible in the interface, or b) use sigset_t internally and may cause breakage if new binaries are used against libraries that don't have the sigset_t change. This not an immediate issue, but will be as soon as applications start using the new range to its fullest.
NOTE: libncurses already had an version bump and has not been given one now.
NOTE: doscmd is a real casualty and has been disconnected for the moment. Reconnection will eventually happen after doscmd has been fixed. I'm aware that being the last one to touch it, I'm automaticly promoted to being maintainer. According to good taste this means that I will receive a badge which either will be glued or mechanically stapled, drilled or otherwise violently forced onto me :-)
NOTE: pcvt/vttest cannot be compiled with -traditional. The change cause sys/types to be included along the way which contains the const and volatile modifiers. I don't consider this a solution, but more a workaround.

Add an include path to private linc/libc_r/libpthread header files.
Define the HIDDEN_SYSCALLS macro as empty because libc doesn't have renamed syscalls. This avoids an undefined macro error when libc/sys/Makefile.inc goes to look though it. HIDDEN_SYSCALLS is used by the equivalent makefile to this one in lib/libc_r to list those syscalls that it needs to rename so that libc_r can provide replacement functions.

Bump shlib minor because xdr_* functions have been enabled. Do NOT bump it again if something else is added before 2.2.
The xdr_* functions are enabled only in the 2.2 (-current) branch so far. If that modification is moved to the 2.1 (-stable) branch, this one should, too.
