2024-05-24sndio: Add a display string to the sioctl_open APIAlexandre Ratchov
For hardware devices, add a server.device control with a single item and the device name as display string. Add the necessary sndioctl(1) bits to print it.

2024-02-04Move ctype.h defines to the _CTYPE_ prefix, avoids clashes with identifiers ↵Jeremie Courreges-Anglas
in ports Even if those _[BCNLPSUX] defines are in the reserved namespace, some ports make use of those identifiers and thus need pointless headscratching and patches. Just use a longer reserved prefix. We can't just #undef those defines as they are used in libc. Change similar to what NetBSD did around 2010. Went through base builds and an amd64 bulk build, the only fallout was lib(e)stdc++ base_ctype.h. "make includes" will install the latest ctype.h and libstdc++ ctype_base.h. "makes sense" deraadt@, ok sthen@ tb@
2023-12-12remove support for syscall(2) -- the "indirection system call" becauseTheo de Raadt
it is a dangerous alternative entry point for all system calls, and thus incompatible with the precision system call entry point scheme we are heading towards. This has been a 3-year mission: First perl needed a code-generated wrapper to fake syscall(2) as a giant switch table, then all the ports were cleaned with relatively minor fixes, except for "go". "go" required two fixes -- 1) a framework issue with old library versions, and 2) like perl, a fake syscall(2) wrapper to handle ioctl(2) and sysctl(2) because "syscall(SYS_ioctl" occurs all over the place in the "go" ecosystem because the "go developers" are plan9-loving unix-hating folk who tried to build an ecosystem without allowing "ioctl". ok kettenis, jsing, afresh1, sthen

2023-09-05According to the C11 standard, char32_t and char16_t are not partIngo Schwarze
of the C language but are part of the C library and have to be declared in <uchar.h> - see paragraph 7.28.2. In stark contrast, according to the C++11 standard, char32_t and char16_t are part of the C++ language, namely, keywords - see paragraph 2.12.1. Consequently, they must not be declared in a header file. To resolve this vile contradiction, use the predefined macro __cplusplus to find out which language is in use for the current compilation unit - see C11 paragraph 6.10.8.3 and C++11 paragraph 16.8.1. Reminded of the problem by naddy@. OK naddy@ who tested in make build / make release. Looks reasonable to millert@.
2023-08-20Provide C11 <uchar.h>.Ingo Schwarze

2022-01-05funopen(): change seekfn argument to use off_t, not fpos_tTodd C. Miller
On BSD, fpos_t is typedef'd to off_t but some systems use a struct. This means fpos_t is not a portable function argument or return value. Both FreeBSD and the Linux libbsd funopen() have switched to off_t for this--we should too. From Joe Nelson. OK deraadt@

2021-11-22Implement rfc6840 (AD flag processing) if using trusted name serversJeremie Courreges-Anglas
libc can't do DNSSEC validation but it can ask a "security-aware" resolver to do so. Let's send queries with the AD flag set when appropriate, and let applications look at the AD flag in responses in a safe way, ie clear the AD flag if the resolvers aren't trusted. By default we only trust resolvers if resolv.conf(5) only lists name servers on localhost - the obvious candidates being unwind(8) and unbound(8). For non-localhost resolvers, an admin who trusts *all the name servers* listed in resolv.conf(5) *and the network path leading to them* can annotate this with "options trust-ad". AD flag processing gives ssh -o VerifyHostkeyDNS=Yes a chance to fetch SSHFP records in a secure manner, and tightens the situation for other applications, eg those using RES_USE_DNSSEC for DANE. It should be noted that postfix currently assumes trusted name servers by default and forces RES_TRUSTAD if available. RES_TRUSTAD and "options trust-ad" were first introduced in glibc by Florian Weimer. Florian Obser (florian@) contributed various improvements, fixed a bug and added automatic trust for name servers on localhost. ok florian@ phessler@

2020-09-06Use __STDC_VERSION__ instead of __ISO_C_VISIBLE to guard _Static_assert.Todd C. Miller
We need to test what the compiler supports, not what the C library provides. This prevents static_assert from being defined when compiling with the in-tree gcc (4.2.1) which does not support _Static_assert.

2020-07-14Fix TIB/TCB on powerpc64. Some bright sould decided that the TCB shouldMark Kettenis
be 8 bytes in the 64-bit ABI just like in the 32-bit ABI. But that means there is no "spare" word in the TCB that we can use to store a pointer to our struct pthread. So we have to treat powerpc64 special. Also recognize that the thread pointer points 0x7000 bytes after the TCB. Since the TCB is 8 bytes this means that TCB_OFFSET should be 0x7008.

2020-02-26Add API to control audio device parameters exposed by sndiod.Alexandre Ratchov
The API exposes controls of modern audio hardware and sndiod software volume knobs in a uniform way. Hardware knobs are exposed through sndiod. Multiple programs may use the controls at the same time without the need to continuously scan the controls. For now sndiod exposes only its own controls and the master output and input volumes of the underlying hardware (if any), i.e. those typically exposed by acpi volume keys. ok deraadt
