| | | | | | | | | | | move their definitions and initialization in static links to libc.a Make crt0 always invoke a new func _csu_finish() in libc to process the auxv and to either register the ld.so cleanup function (in dynamic links) or initialize environ and __progname and do MC_DISABLE_KBIND (in static links). In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@

* Remove doaccess variable and access(2) call since this interfers withmestre2016-03-141-11/+2
| | | | | | | | | | | | | | | | applications like zdump(8) because pledge(2) doesn't allow access(2) to /usr/share/zoneinfo. millert@ better described why this call can go away: "This looks like an attempt to do access checks based on the real uid instead of the effective uid. Basically for setuid programs we don't want to allow a user to set TZ to a path they should not be able to otherwise access. However, we already have a check for issetugid() above so I think the doaccess bits can just be removed and we can rely on open()." After discussion with tb@, deraadt@ and millert@, this was also OK'ed by them

* Remove sentences in RETURN VALUES sections saying that functions withmmcc2016-03-124-25/+8
| | | | | | | | | | | | | void return types 'return no value'. This is obvious and therefore unneccessary to mention. We spare rewind(3)'s sentence because espie@ pointed out that it's a warning - the function masks a potential error. This commit also adds a sentence to X509_free clarifying that it's NULL-safe. This bit was discussed with doug@. ok martijn@, sentiment supported by schwarze@

* If an incomplete character is passed to mbtowc(3), set errno to EILSEQ.schwarze2016-02-271-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is unambiguously required both by POSIX and by our own manual page. It also makes a lot of sense because having a function that can fail and that sets errno in some failure modes but does not set errno in other failure modes would be a terrible idea. Such a function would be ridiculously complicated to use. To detect the reason for failure, you would have to: - save errno - reset errno to zero - call the function - inspect the return value to detect failure - inspect errno to decide about the reason for failure - if errno is zero, restore the saved errno That is completely unreasonable, in particular for a seemingly innocous function like mbtowc(3). Next to no programmer would get that right in any real-world program. Note that this bug is very widespread, it also affects NetBSD, FreeBSD, Solaris 11, and glibc. I will also send a note around to the other systems. There may be fallout from programs using the interface incorrectly. If you run into any, please report that to me. OK millert@
