Prepare the system for _FORTIFY_SOURCE Notably: - libc needs to #undef some of the macros from ssp/* for underlying implementations - ssp/* wants a __RENAME() macro (snatched more or less from NetBSD) There's some extra hinkiness included for read(), since libc spells it as "_read" while the rest of the world spells it "read."

General further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

If the size passed to {,v}s{w,n}printf is larger than INT_MAX+1 (i.e., the return value would overflow), set errno to EOVERFLOW and return an error. This improves the chances that buggy applications -- for instance, ones that pass in a negative integer as the size due to a bogus calculation -- will fail in safe ways. Returning an error in these situations is specified by POSIX, but POSIX appears to have an off-by-one error that isn't duplicated in this change. Previously, some of these functions would silently cap the size at INT_MAX+1, and others would exit with an error after writing more than INT_MAX characters. PR: 39256 MFC after: 2 weeks

Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into __sFILE. This was supposed to be done in 6.0. Some notes: - Where possible I restored the various lines to their pre-__sFILEX state. - Retire INITEXTRA() and just initialize the wchar bits (orientation and mbstate) explicitly instead. The various places that used INITEXTRA didn't need the locking fields or _up initialized. (Some places needed _up to exist and not be off the end of a NULL or garbage pointer, but they didn't require it to be initialized to a specific value.) - For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to avoid namespace pollution of including all the pthread types in stdio.h. Once we remove all the inlines and make __sFILE private it can go back to using pthread_t, etc. - This does not remove any of the inlines currently and does not change any of the public ABI of 'FILE'.

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. Approved by: -arch

The new declaration of `on' was disordered (integer types go together). 4. Testing an unsigned value for > 0 was fishy. Submitted by: bde

1) Oops! Insert again if (n == 0) return 0. Final word is Bruce's quote: C9x specifies the BSD4.4-Lite behaviour: [#3] ... Thus, the null-terminated output has been completely written if and only if the returned value is less than n. It means that if we not have any null-terminated output as for n == 0 we can't return value less than n, so we forced to return value equal to n i.e. 0 The next good thing is glibc compatibility, of course. 2) Do check for too big n in machine-independent way. 3) Minor optimization assuming EOF is < 0

Back out part related to "return 0 if n == 0" and return EOF as before. The main argument is that it is impossible to determine if %n evaluated or not when snprintf return 0, because it can happens for both n == 0 and n == 1. Although EOF here is good indication of the end of process, if n is decreased in the loop... Since it is already supposed in many places that EOF *is* negative, f.e. from Single Unix specs for snprintf "return ... a negative value if an output error was encountered" this not makes situation worse.

snprintf return value fixes to conform Single Unix specs: 1) if buffer size is smaller than arguments size, return buffer size, not arguments size as before. 2) if buffer size is 0, return 0, not EOF as before. (now it is compatible with Linux and Apache implementations too). NOTE: Single Unix specs says: If the value of n {buffer size} is zero on a call to snprintf(), an unspecified value less than 1 is returned. It means we can't return EOF since EOF can take *any* value in general not especially < 1. Better variant will be return -1 (it is less then 1 and different with n == 1 case) but -1 value is already occuped by EOF in our implementation, so we can't distinguish true IO error in that case. So 0 here is only possible case still conforming to Single Unix specs.

Suggested by: Bruce Evans, Jeffrey Hsu, Gary Palmer Added $Id$'s to files that were lacking them (gpalmer), made some cosmetic changes to conform to style guidelines (bde) and checked against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde) One last code cleanup:- Removed spurious casts in fseek.c and stdio.c. Added missing function argument in fwalk.c. Added missing header include in flags.c and rget.c. Put in casts where int's were being passed as size_t's. Put in missing prototypes for static functions. Changed second args of __sflags() inflags.c and writehook() in vasprintf.c from char * to const char * to conform to prototypes. This directory now compiles with no warnings with -Wall under gcc-2.6.3 and with considerably less warnings than before with the ultra-pedantic script I used for testing. (Most of the remaining ones are due to const poisoning).
