2019-07-14Unlike gas, clang's assembler complains about duplicate symbol assignments.Philip Guenther
Tweak the PSEUDO() macro to avoid that. problem noted and tested by kettenis@

2019-07-12Add affinity between the program and its mixer control.Alexandre Ratchov
Currently, if there are two instances of the same program, sndiod will allocate one volume control to each. If both programs disconnect and reconnect, the information of which control is assigned to which program is lost. This makes difficult to run two instances of a player and crossfade between each other with a MIDI controller. To address this, the program chooses a 32-bit "id" (for now the process pid) and sends it to the server. The server records the id in the client's slot structure. When the server accepts a new connection, it uses the id to identify the slot the client used during the previous connection; if it was not recycled yet, it's assigned to the program.
2019-07-11Using pthread_atfork instead of __register_atfork with uClibc on noMMUKinichiro Inoguchi

2019-07-09Group tls_{handshake,read,write,close}() return values documentation.Joel Sing
Move the documentation for tls_error() down so that both the special return values for tls_{handshake,read,write,close}() directly follow the standard return values for the same functions. Prompted by deraadt@. ok deraadt@ schwarze@

braces. no objection from jmc@ and schwarze@
2019-07-08Clean up pvkfmt.cKinichiro Inoguchi
- Replace EVP_CIPHER_CTX_init with EVP_CIPHER_CTX_new and handle return value - Replace EVP_CIPHER_CTX_cleanup with EVP_CIPHER_CTX_free - Change two 'return -1;' to 'goto err;' for avoiding leak - Remove the case if enclevel == 0 - Change enclevel checking to make more consistent - Change all goto label to 'err' and insert space before goto label ok and advise from tb@
2019-07-07Fix pvk format processing in libcryptoKinichiro Inoguchi

2019-07-05The last consumer of pre-posix realpath behaviour has stoppedTheo de Raadt
requiring it (sftp-server). Remove the /exists///// behaviour from here. The /nonexistant behaviour remains in the kernel and needs to be shot next. There may be ports fallout, but we doubt it. ok beck djm

CVE-2018-20843, a potential denial-of-service in libexpat due to high RAM and CPU usage. OK deraadt@
2019-06-28Specify that {v,}asprintf(3) returns precisely -1 on failure,Ingo Schwarze
and that the ret pointer is either unchanged or set to NULL in this case. Since these two functions are not standardized by POSIX, documenting the actual behaviour is the way to go, and the above matches all non-buggy implementations we are aware of. OK millert@ deraadt@
2019-06-28Actually, the C standard only guarantees that atexit(3) returns non-zeroIngo Schwarze
on error, so tweak previous to test "atexit(...) != 0" for portability. "OK ok ok sorry backwards" deraadt@
2019-06-28Since clang only supports the "secure" PLT ABI for "big" PIC/PIE on powerpc,Mark Kettenis
stop building the csu code with -fpie on that platform. ok guenther@, visa@
2019-06-28When system calls indicate an error they return -1, not some arbitraryTheo de Raadt
value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

2019-06-27The C89 standard only requires that atexit(3) returns a non-zero valueIngo Schwarze
on error, so checking for -1 only is potentially non-portable. Also mention that the C89 standard does not require errno to be set. OK deraadt@ millert@

set subq_h_errno and ar_count. Remove the ar_datalen == -1 check, so we set ar_h_errno and don't have to (wrongly) guess that ar_h_errno = HOST_NOT_FOUND. This makes sure that if no nameserver responds the h_errno value is set to TRY_AGAIN instead of HOST_NOT_FOUND. OK eric@, deraadt@

2019-06-25POSIX.1-2008 TC3 is going to clarify how newlocale(3) uses oldloc.Ingo Schwarze
Explicitly state that our implementation now complies with the stricter requirements of TC3 because the newlocale(3) in old OpenBSD releases only complied with the weaker requirements of the old text of the standard. The complaints from our users resulted in both our implementation and the standard being improved. For details, see: http://austingroupbugs.net/view.php?id=1243#c4347

2019-06-21Fix conversions to long double on sparc64Jeremie Courreges-Anglas
Bug exposed by erratic sqlite3 behavior used in ports/devel/proj, as pointed out by landry@. Richard Hipps (SQLite) pointed at the culprit (_Qp_div), many thanks. Adapted from FreeBSD revision 146673 by Stephen Paskaluk and stefanf@FreeBSD. FreeBSD commit message: """ Fix long (and long long) to long double, unsigned to long double and unsigned long (and unsigned long long) to long double conversions. - Add a parameter that specifies the position of the sign bit to the _QP_TTOQ macro, previously it always looked at bit 31. Pass a negative number to disable sign inspection for unsigned types. This fixes _Qp_xtoq(), _Qp_uitoq() and _Qp_uxtoq(). - In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to decide whether we're doing a conversion from an unsigned type. If so, don't negate the mantissa if the integer exceeds the biggest signed number. """ ok deraadt@

2019-06-20sockatmark(3), recv(2), getsockopt(2), and connect(2) return specificallyTheo de Raadt

2019-06-17Make BN_num_bits_word() constant time.Theo Buehler
Previously, this function would leak the most significant word of its argument due to branching and memory access pattern. This patch is enough to fix the use of BN_num_bits() on RSA prime factors in the library. The diff is a simplified and more readable (but perhaps less efficient) version of https://github.com/openssl/openssl/commit/972c87df by Andy Polyakov and David Benjamin (pre license change). Consult that commit message for details. Subsequent fixes to follow in the near future.
