* upstream: AIX reports the CODESET as "ISO8859-1" in the POSIX locale.schwarze@openbsd.org2018-08-221-4/+9
| | | | | | | | | | | | | Treating that as a safe encoding is OK because even when other systems return that string for real ISO8859-1, it is still safe in the sense that it is ASCII-compatible and stateless. Issue reported by Val dot Baranov at duke dot edu. Additional information provided by Michael dot Felt at felt dot demon dot nl. Tested by Michael Felt on AIX 6.1 and by Val Baranov on AIX 7.1. Tweak and OK djm@. OpenBSD-Commit-ID: 36f1210e0b229817d10eb490d6038f507b8256a7

| | | | | | | | | Switch to recallocarray() for a few operations. Both growth and shrinkage are handled safely, and there also is no need for preallocation dances. Future changes in this area will be less error prone. Review and one bug found by markus Upstream-ID: 822d664d6a5a1d10eccb23acdd53578a679d5065

| | | | | | | | | Recognize nl_langinfo(CODESET) return values "646" and "" as aliases for "US-ASCII", useful for different versions of NetBSD and Solaris. Found by dtucker@ and by Tom G. Christensen <tgc at jupiterrise dot com>. OK dtucker@ deraadt@ Upstream-ID: 38c2133817cbcae75c88c63599ac54228f0fa384

| | | | Unbreak obvious syntax error.
* Yet another synonym for ASCII: "646"Damien Miller2017-03-201-1/+1
| | | | | Used by NetBSD; this unbreaks mprintf() and friends there for the C locale (caught by dtucker@ and his menagerie of test systems).
* upstream commitdjm@openbsd.org2017-02-191-2/+3
| | | | | | | | Add a common nl_langinfo(CODESET) alias for US-ASCII "ANSI_X3.4-1968" that is used by Linux. Fixes mprintf output truncation for non-UTF-8 locales on Linux spotted by dtucker@; ok deraadt@ schwarze@ Upstream-ID: c6808956ebffd64066f9075d839f74ff0dd60719

| | | | | | | | | In vasnmprintf() return an error if malloc fails and don't set a function argument to the address of free'd memory. ok djm@ Upstream-ID: 1efffffff2f51d53c9141f245b90ac23d33b9779
* Force Turkish locales back to C/POSIX; bz#2643Damien Miller2016-12-121-0/+42
| | | | | | | | | | Turkish locales are unique in their handling of the letters 'i' and 'I' (yes, they are different letters) and OpenSSH isn't remotely prepared to deal with that. For now, the best we can do is to force OpenSSH to use the C/POSIX locale and try to preserve the UTF-8 encoding if possible. ok dtucker@

| | | | | | | | | | | | | Even when only writing an unescaped character, the dst buffer may need to grow, or it would be overrun; issue found by tb@ with malloc.conf(5) 'C'. While here, reserve an additional byte for the terminating NUL up front such that we don't have to realloc() later just for that. OK tb@ Upstream-ID: 30ebcc0c097c4571b16f0a78b44969f170db0cff

| | | | | | | | | | | | | | | Fix two rare edge cases: 1. If vasprintf() returns < 0, do not access a NULL pointer in snmprintf(), and do not free() the pointer returned from vasprintf() because on some systems other than OpenBSD, it might be a bogus pointer. 2. If vasprintf() returns == 0, return 0 and "" rather than -1 and NULL. Besides, free(dst) is pointless after failure (not a bug). One half OK martijn@, the other half OK deraadt@; committing quickly before people get hurt. Upstream-ID: b7bcd2e82fc168a8eff94e41f5db336ed986fed0

To prevent screwing up terminal settings when printing to the terminal, for ASCII and UTF-8, escape bytes not forming characters and bytes forming non-printable characters with vis(3) VIS_OCTAL. For other character sets, abort printing of the current string in these cases. In particular, * let scp(1) respect the local user's LC_CTYPE locale(1); * sanitize data received from the remote host; * sanitize filenames, usernames, and similar data even locally; * take character display widths into account for the progressmeter. This is believed to be sufficient to keep the local terminal safe on OpenBSD, but bad things can still happen on other systems with state-dependent locales because many places in the code print unencoded ASCII characters into the output stream. Using feedback from djm@ and martijn@, various aspects discussed with many others. deraadt@ says it should go in now, i probably already hesitated too long Upstream-ID: e66afbc94ee396ddcaffd433b9a3b80f387647e0
